Description

[Detailed Description of the Invention] It relates to a traveling circular saw machine, and more specifically, it is equipped with a table having a slit for running a blade so as to be rotatable with respect to the frame, and is mounted and held on the table in brackets so as to be placed on the underside. The most scarlet feature of the ejecting device for a rotary cutter is that it is equipped with a material holding member that also serves as a safety cover and a feeding device on the top side, and with the above-mentioned configuration, it is easy to handle and has high workability. The purpose of this project is to provide a traveling circular saw machine that has excellent performance and high safety.

An embodiment of the present invention will be specifically described below based on the drawings.

1 and 2 show a partially vertical side view and a plan view, respectively, of a traveling circular saw machine, which has a box-shaped frame with a reference numeral 1, and a busy circular concave hole 2 in the center of the upper surface of the frame 1. A receiving rotor 3.3 is provided at intervals at the bottom of this recessed hole 2.
cast.

Reference numeral 4 denotes a circular table fitted in the recessed hole 2, the peripheral edge 5 of which is shown in FIG. 2 as the receiver 3.3.
．． It is supported by both of 6 and guided in the vertical direction and rotational direction.

Incidentally, one of the above-mentioned transfer children is a motor M.

It is assumed that the table 4 is driven and the table 4 is rotated automatically. The motor M1 is driven forward and reverse by a manual operation switch (not shown).

Further, a cutting edge plate 7 is attached to the center of the tape/L/4, and the cutting edge plate 7 is provided with a single slit 8 for running the knife. Reference numeral 9.9 denotes a material feeding guide plate disposed on the H side of the tape/L/4, which is divided into two approximately at the center and each end of which is fixed to the side of the frame 1.
It is arranged in the left-right direction - line - H in FIG.

Next, each member disposed on the lower surface of the table 4 will be explained.

Reference numerals 10B and tab refer to the knife running slit 8.
A pair of left and right horizontal rails are arranged on the lower surface of the tape//4 in parallel with the tape/L/4, and both ends of each are fixed to the tape/L/4 using the metal fittings 11 and 11K. The movable base 12 is slidably engaged with the horizontal rail 11.11, and the movable base 12 is reciprocated by a fluid cylinder type traveling mechanism A. That is, the piston rod 14 in the fluid cylinder is mounted on the movable table side KF8I, and the cylinder tube 15 is fixed to the support plate 111. By operating the piston rod 14 in the shortening direction shown in FIG. move in the cutting direction. Further, a vertical guide 16 extending downward is disposed on the lower mounting surface of the movable platform, and a tool post 17 is engaged with this vertical guide 16 via a vertical structure B. Nut on the side of the tool post 17 constituting the raising/lowering mechanism B described by No. 18 Company F. This feed screw 19 is connected to the motor M via the gear
Related to 2, motor drive I! I11 is used to adjust the nut slide, that is, the tool rest 17, to F-down, and this movement controls the protrusion and retraction of the rotary cutter, which will be described later, from the table surface. Then F
The combination of the traveling mechanism A and the elevating mechanism B constitutes a rotating blade ejecting device.

The symbol η is a strong blade shaft rotatably supported by a bearing tube mounted on the upper end of the turret 17. K3 is a rotating blade.
is a moving motor for a rotating blade example.

The above example of a rotary cutter is one whose elevation is controlled by a limit switch (not shown) associated with motor M21C, and is first drawn at the start of the process (right position in Fig. 1) to protrude a specified dimension onto tape Iv4. In this protruding state, the piston rod 14 is extended to reach the end of the process (the first
The knife is moved toward the cutter position shown in the figure, and is immersed in the tape/l/4 when reaching the end of the process, and then returned to the start of the process by shortening the piston rod 14 in this immersed state. During the cutting process, this operation cycle is sequentially repeated at H8 and back.

Next, the top side of table 4 1ttIV! Each member that played a role will be explained.

In other words, the code 5.25 is a vertical guide established on the inside of the tape /l/4, and the elevating body part has an elevating body part of ``engage the elevating body I with the nuclear vertical guide j1''.・Is it okay to store 91? +Falling structure C Kepak t guide '6,? 5 (to the river) (g) with the feed screw η and the nuts attached to the elevating body part. Roll night feed 't 'II p!゛・K is prepared by the operation.

Also, the front side of the i-edited money sending device (female 4erF in Figure 1)
q) is provided with a material holding member (material) which also serves as a safety cover and is connected to approximately half of the slit 8 for running the cutter.
i) It is attached and held on the f-elevating body%. Then, it is operated by a fluid cylinder η associated with one link 31 to move up and down, and pushes the workpiece #1 to the table surface.

At the same time, the order of protrusion of the rotary knife U is reversed.

Note that this material holding part t is operated in conjunction with the operation cycle rvVC of the rotary blades described above, and presses and fixes the material to be processed before cutting by the rotary blade 24; When the machining is completed and the rotary blade is immersed within the table surface, it retreats upward. Next (the one indicated by C code ρ... is an auxiliary table of idle roller type arranged in the left and right direction of table 4. It is attached to the tip of the piston rod of the fluid cylinder with the rotation stop mechanism of E tape/I/4. The rotating position of the table 4 is regulated by applying pressure to the circumferential part 5.

In one embodiment of the present invention, it is possible to cut the end face of the workpiece at a right angle, since the cutting direction is as shown in the figure 21. After setting the cutting tool running slit 8 perpendicular to the (left and right direction) and setting the material along the material feeding guide plate 9, ) in this state a@, the rotary cutting tool U is moved according to a predetermined cycle of operation. Let them drive. In this way, the front surface of the work can be guarded by the material holding member I for the safety force t<-tll, and the safety VC work can be completed.

Next, when cutting the workpiece material diagonally, motor M1
By driving, the blade/I/4 is rotated 17 and the cutter running slit 8 is set to the required angle. This iQ, the rotating blade U placed on the lower surface side as the tape lv4 moves.
The ejection device, and the material holding member (supply) placed on the H side of 1 are -? )? Itc is summoned,
There is no need to determine the injection angle at each angle, and the work can be carried out quickly.

Furthermore, when cutting the workpiece material along its longitudinal direction, the slit 8 for running the blade is set parallel to the material feeding guide plate 9.9 by driving the qt* motor M as described above. In this case as well, the material feeding device @D can be set in the direction of the material feeding guide plate 9.9, that is, the direction of tape μ feeding, at the same time as the rotation operation, and the height of the material feeding device can be adjusted by adjusting the height of the material feeding device. C to adapt the thickness of the material, and then table 4
By sizing from a single call, it is possible to process the material in the longitudinal direction while automatically feeding the material. For Naoto's Tanekacho rod, the material holding member I is placed above the feeding # interval at vQ +ii
Let me do it.

As described in detail below, the present invention is such that a table having a slit for running the blade S is rotatably mounted on the frame, so that it can be attached to the tape /L/. Hold it and have a protrusion of the rotating blade on the bottom side #! Place the material holding member on the A side, and then move the material #! Equipped with a device, it has the advantage of not having to adjust the movement of each of these devices independently. For this reason■
Corner cutting processing, ladle cutting processing Saranyo exhibits the effect that various processing such as longitudinal cutting processing can be performed extremely easily and quickly.
