Abstract

PURPOSE:To shorten the idle time to wait the extruder by providing an attached table of the same length as an initial table at an extruder side of a cooling table continuously to this cooling table. CONSTITUTION:An attached table 30 is set at the extruder 1 side of the 1st cooling table 4 continuously to this cooling table 4. When a head side of the shape material is mounted on an initial table 20, the shape material is transferred or passed to the cooling table 4, and the shape material is brought forward on the table 20 by the length equal to that of this initial table. Therefore, the waiting time of the extruder can be shortened because a puller can be returned to the extruder side by the time spent for bringing out in the previous method.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an aluminum extruded shape (hereinafter referred to as a shape).
The present invention relates to back surface processing equipment and a processing method, and more specifically, it relates to back surface processing equipment and a back surface processing method in which a section is extruded, then pulled on a runout table, cooled on a cooling table, etc.

More specifically, the present invention includes an initial table attached to an extruder, a cooling table arranged in parallel with a runout table, an initial shear, a puller, and a cooling stock provided on the cooling table. The present invention relates to an improvement in a rear surface treatment equipment for a profile including a retcher, and an improvement in a rear surface treatment method using the equipment.

[Prior Art] FIG. 7 is a perspective view showing an example of the above-described type of profile rear surface processing equipment having two cooling tables, and FIG. 8 is a plan view. In the figure, 1 is an extruder, 2 is a puller, 3 is a runout table, 4 is a first cooling table, 5 is a second cooling table, 6 is a stretcher headstock that performs stretching, and 7 is a Tail stock that moves and holds the end of the section,
8 is the second cooling table 5 and storage table 9
9 is a storage table for storing stretched shapes; 10 is a second transfer table for transferring shapes from storage table 9 to saw table 11; 12 is a storage table for storing stretched shapes; 12 is a storage table for storing stretched shapes; 13 is a sizing machine, 14 is a saw gauge table, 15 is a third transfer table, 16 is an inspection table, and 18 is an initial shear (also called a platen shear or platen saw).

When a section is cooled using the equipment shown in Figure 7.8, depending on the shape of the section, both ends of the section may be in the second position when cooling is completed.
It is floating above the surface of the cooling table 5,
In addition, both ends of the section were twisted, making it difficult to catch the section with the chuck of the stretcher headstock 6 or tail stock 7. In order to improve this, a cooling stretcher is installed on the first cooling table 4, which grips both ends of the shape to prevent it from twisting or falling during the cooling process, and can cool the shape while straightening it with a constant tension. Preparations were made for the
(Refer to Publication No.-18568).

In addition, in the conventional back processing method, the drive device of the runout table 3 was used to transport the profile to a position where it could be transferred to the first cooling table 4 as soon as extrusion was completed, but in the recent back processing method, The section cut off with the initial shear 18 is made into the initial table 20 with the puller 2.
Compared to the conventional method, the stopping positions at both ends of the shape can be stopped with extremely high precision, allowing unattended use of the stretcher (6, 7) or cooling stretcher (not shown). The chuck now grips the shape reliably.

The above two improvements have made it possible to make the rear processing equipment unmanned.

[Problems to be Solved by the Invention] However, as the idle time of recent extruders, that is, the billet supply time to the extruder has been shortened, when carrying out the shape material removal using the puller described above, it is difficult to finish supplying billets. The extruder has to wait several seconds for extrusion during puller retraction time, which hinders productivity. As a countermeasure to this problem, a double puller is attracting attention, in which two pullers are prepared, and one puller is used for each extrusion, and one puller is used alternately for pulling the shape. However, in this method, the equipment cost increases significantly due to the use of two pullers.

On the other hand, the conventional system in which a drive device is provided on the runout table results in a pick-and-run system with poor stopping position accuracy of the profile.

In addition, the initial table in the rear equipment of the extruder is required as a work area where humans intervene, such as inspecting shaped materials, so the initial table is necessary as the equipment at the rear of extrusion.

Therefore, the present invention provides a back-processing equipment and a back-processing method that shorten the idle time during which the extruder waits when the profile is carried away by a length equivalent to the initial table in the back-processing equipment that uses one puller. The purpose is to

[Means for Solving the Problems] The rear processing equipment according to the present invention includes an initial table attached to an extruder, a runout table, an initial shear, a hanging puller, and a cooling unit installed in parallel with the runout table. In a rear processing equipment for aluminum extruded shapes that includes a table and a cooling stretcher installed on the cooling table, an attached table with approximately the same length as the initial table is installed on the extruder side of the cooling table. The tail side chuck of the cooling stretcher is provided continuously with the table, and the head side grips the tail side of the aluminum profile transferred to the attached table,
The cooling stretcher is characterized in that the head side is movable until it reaches a position on the head side of the cooling stretcher.

The attached table, which is a feature of the present invention, may have any structure as long as it supports the profile and allows the profile to be moved in the longitudinal direction. For example, the attached table may include a free conveyor or free rollers arranged in the extrusion direction. The attached table must be provided with approximately the same length as the initial table; if the attached table is too short, the profile will bend, and if it is not long, the installation area will increase and there is no particular advantage.

To transfer the shapes from the initial table to the attached table, a transfer mechanism for the first cooling table may be provided on the initial table, and if the existing rear equipment is to be renovated, the shapes held by the cooling table can be transferred. It is preferable to extend the mounting mechanism to the attached table. That is, the tilting type belt conveyor for transferring shaped materials, which was provided in the conventional cooling table, can be provided in an overlapping manner up to the area of the attached table.

The attached table needs to be provided continuously with the cooling table so that the shaped material being carried away can be moved smoothly from the attached table to the cooling table without bending or deflecting.

Another feature of the present invention is the mechanism on the tail side of the cooling stretcher. In other words, the tail chuck grips the profile when the profile is not stretched and holds the cooling table for a length corresponding to the length of the stretch (for example, several meters). ) There is also a mechanism that moves freely. For this movement, the tail chuck must be of a hanging type, located above the cooling table. In other words, if the tail chuck runs under the cooling table and sticks its head out above the table when gripping the profile, the tail chuck will interfere with the rollers of the cooling table and the profile will be damaged. It becomes difficult to escape. Therefore, in the present invention, the cooling stretcher must be of a so-called hanging type, that is, the cooling stretcher must move with its movable parts (jumps, claws, etc.) positioned above the cooling table.

The tail side chuck of the cooling stretcher of the present invention is provided with a carry-out function. i.e. the tail end of the aluminum profile (located on the cooling table) with the head side transferred to the attached table and the profile tail at the start of the cooling stretch (when the head side of the profile reaches the position on the headstock side). It has the function of gripping and moving the shape between the ends.

A preferable system for making the post-processing equipment of the present invention unmanned includes a means for instructing the transfer or transfer of the profile to the cooling table after cutting the profile by the initial shear, and a means for instructing the transfer or transfer of the profile to the cooling table after confirming the completion of the transfer. It is provided with means for instructing the tail side to carry and release the profile, and means for instructing the puller to return to the extruder after confirming transfer of the profile to the cooling table.

Further, the method for processing the back surface of a profile according to the present invention includes cutting the profile on the initial table and the runout table with an initial shear, and then transferring the profile from the initial table and the runout table to the cooling table.
Grasp the profile by the tail side of the cooling stretcher, carry out the profile by the length of the initial table on the cooling table, and immediately after transferring the profile to the outside of the initial table and runout table, move the puller near the extruder. It is characterized by returning to.

[For Initial Use] In conventional back processing equipment, the profile is placed on the initial table 2.
0 (see FIG. 8) was carried away by the puller 2 and then transferred to the first cooling table 4, so there was an open space on the extruder 1 side of the first cooling table 4. In the present invention, an attached table is provided here continuously with the cooling table. Furthermore, the conventional cooling stretcher was a device exclusively for (sub)stretching the shaped material obtained through the initial table 20 and the runout table 3 while it was being cooled, but in the present invention, it is equipped with a carry-out function. As a result, the carry-and-run function was removed from the puller.

Carrying away with a cooling stretcher can be carried out with the same precision as lifting with a puller, and since both ends of the profile can be accurately stopped, the profile can be delivered to the cooling stretcher with high precision.

In the conventional back processing method, the profile is placed on the initial table 2.
0 (see FIG. 8) by the puller 2, and after the entire profile was placed on the runout table 3, the profile was transferred to the first cooling table 4. In contrast, in the present invention, when the head side of the profile is on the initial table, the profile is transferred or transferred to the cooling table, and the profile is carried away on the cooling table by an amount equivalent to the length of the initial table. Therefore, the puller can return to the extruder side in the time that would have been spent carrying it away in the conventional method, reducing the waiting time of the extruder.

Hereinafter, embodiments of the present invention will first be described in detail with respect to a facility with two cooling tables, and then will be explained in detail with respect to a facility with one ring table, as disclosed in Japanese Patent Publication No. 2-42564 of the present applicant. An example will be explained.

(Example) Fig. 1 is a plan view showing the overall layout of the rear processing equipment of the present invention, and a table attached to the rear processing equipment in Figs. 30 is provided, and a cooling stretcher and -22 are also provided. 23 and 24 are the tail stock and head stock of the cooling stretcher 22, respectively.

Figure 2 is a drawing of the rear processing equipment seen from the extruder side.
In particular, it shows a hanging type cooling stretcher and its peripheral equipment.

First, regarding the puller 6 and its accessory devices, 25 is a puller arm, 26 is a puller rail on which the puller arm 25 runs via a bearing, 27 is a storage section fixed to the puller rail 26, and 28 is a storage section 27. A desired number of blades (also called claws) are housed in 27 so as to be movable back and forth depending on the shape of the profile, and 31 is a support frame structure for holding all of these blades. Further, 32 is a fan that forcibly cools the shape on the lunch-out table 3.

The runout table 3 is constructed by arranging a large number of free rollers 35 and does not have a drive mechanism. That is, the free roller 35 merely guides the profile being pulled by the puller 2, and does not advance the profile by roll drive. A belt conveyor 36 of the first cooling table 5 is provided at the position of the free roller 35 of the runout table 3. belt conveyor 3
The wheel 37 around which the 6 is wrapped at one end is in a sunken position as shown in the figure when the runout table 3 is in operation, and when the profile is transferred to the first cooling table 4, the belt conveyor 36 pulls it up to a horizontal position. (see thin line), the profile is removed from the free roller 35, and the profile is transferred to the outside of the runout table 3 by rotation of the wheels 37 and 39. A fixed flat table made of heat-resistant felt is provided in the middle of the belt conveyor 36, and its horizontal level is lower than when the first cooling table 4 is ascending and higher than when it is descending. 40 is an air cylinder, 41 is a piston rod connected via a joint, 42 is a lifting rod,
These allow the belt conveyor 36 to be used before and after the section is transferred.
The position of rises and falls.

Next, the cooling stretcher will be explained. 4
5 is a beam that hangs the entire cooling stretcher, 4
Reference numeral 6 indicates an upper cooling fan for cooling the profile, 47 indicates a blade (also called a claw), 48 indicates a storage area for the blade 47, 49 indicates a support part for suspending 47 and 48 from the beam 45, and 50 indicates a support for the profile. This is a lower cooling fan. Once the profile has been cut by the initial shear 18 (see FIG. 1), the blades 28 of the puller 2 release the profile and the belt conveyor 36 subsequently rotates around wheels 39 upwards to a horizontal position. The profile is transported by a belt conveyor 36 to below the cooling stretch or -. Subsequently, the tail stock 23 grips the tail side of the profile with the blade 23 as shown in the figure and moves toward the tail, for example, about 3 m, and drags the profile on the heat-resistant felt table. During this time, the entire blade on the head side (not shown) of the cooling stretcher is stored in the storage section, so the profile moves without interfering with the headstock. After the lift-off is completed, the shape can be stretched to put tension on it. The method of applying tension is not particularly limited, and a method of applying constant tension (see Japanese Patent Publication No. 2-42564), a method of keeping strain constant, a method of keeping the length of the shape constant, etc. can be adopted. can. Next, the rear surface processing method of the present invention will be explained in detail with reference to the flowchart of FIG. 3 and the time chart of FIG. 4.
