Description

[Detailed explanation of the idea] The present invention relates to a recombination device for shearing machine blades.

The shear frame of a shearing machine for shearing wire rods, steel bars, steel strips, etc. forms a C-shape when viewed from the material conveyance direction, and in order to change the blades in such a shear machine, the blades must be removed from the side of the shear frame. Must be pulled out and installed.

Conventionally, the blades of a shearing machine with the above structure are changed by
This is done by pulling out the turret from the side of the frame using a porter bar and assembling it. Therefore, it is troublesome to position the turret during assembly, and it is also necessary to correct the position after assembly, making it difficult to reassemble. The work required a lot of time.

The recombining device for shearing machine blades of the present invention was developed in view of the above, and includes the upper and lower tool rest mounting parts of the shearing machine.
Provided with guide portions for respectively guiding the upper and lower tool rests in a direction intersecting the feeding direction of the material to be sheared, and communicating with the upper and lower tool rest guide portions for guiding the upper and lower tool rests, respectively; It is equipped with a transportable changing table incorporating a lower tool post guide, a device for transporting the changing table, and a pedestal supporting the changing table at the tool post changing position on the side of the shearing machine. It is characterized by:

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, in a shearing machine for wire rods, steel bars, steel strips, etc., which has a C-shaped shearing machine frame 1 when viewed from the material conveyance direction, the tool rest 3 supporting the upper blade 2 is shown in FIG. As shown, the upper tool post tightening cylinder device 5 is tightened in the tip groove 4a formed in the upper tool post mounting portion of the tool post up/down mechanism 4 (the clamping force is applied by the spring 5a). By applying hydraulic pressure to part A of 5, the clamp is released and the tool post 3 can be pulled out to the side of the shear frame 1 along the tip groove 4a of the tool post up/down mechanism 4. Further, the tool rest 7 supporting the lower blade 6 is provided with a lower tool rest tightening cylinder device 8 similar to the upper tool rest tightening cylinder device 5 on the shearing machine frame 1.
By applying hydraulic pressure to part B of the cylinder device 8, the clamp by the spring 8a is released, and the shearing machine frame 1 is tightened along the groove 1a formed in the lower tool rest attachment part of the shearing machine frame 1.
It can be pulled out to the side.

As shown in FIGS. 1 to 3, the device of the present invention used for changing the blades of a shearing machine having such a configuration has an upper tool rest 3 that communicates with the tip groove 4a of the shearing machine.
The upper blade guide 9 and the groove 1 of the shearing machine
a, and a lifting jig such as a crane for transporting the changing table 11 (in the figure, a crane) (only the wire rope 12 is shown) and a mount 13 that supports the changing table 11 at a predetermined turret changing position on the side of the shear frame 1. The recombination table 11 is placed on the pedestal 13 while fitting into the positioning jig 15 provided on the pedestal 13, and in this state, the operator grasps the handle 16 and pulls out the upper tool rest 3 from the shearing machine frame. Then, the upper tool rest 3 engages with the upper tool rest guide 9 while being guided by the tip groove 4a of the tool rest vertical mechanism 4, and the lower tool rest 7 is pulled out from the shear frame 1 by grasping the handle 17. The lower tool rest 7 can be transferred from the groove 1a of the shear frame 1 to the lower tool rest guide 10.

The upper and lower tool rests 3 and 7 that have been moved from inside the shear frame 1 into the reassembly table 11 are assembled using a lifting jig such as a crane used to transport the reassembly table, as shown in Fig. 2. Either it is extracted from the changing table 11 and transported to a predetermined location, or it is assembled in the changing table 11 and transported to a predetermined location by a crane or the like. In addition, when the upper and lower tool rests 3 and 7 that have been newly installed on the reassembly table 11 are to be assembled into the shearing machine frame 1, simply place the recombination table 11 at a predetermined position on the mount 13, and then simply insert the upper and lower tool rests 3 and 7 into the shearing machine frame 1. The upper and lower tool rests can be set in the proper position simply by pushing 7, and old and new tools can be easily, safely, and reliably replaced.

In the above-mentioned embodiment, an example was shown in which the tool rest was manually pulled out from the shear frame and assembled, but the power may be a cylinder device or a motor, and other embodiments described above may be used without departing from the gist of the present invention. Of course, various changes can be made to.

According to the shearing machine cutter rearrangement device of the present invention having the above-described structure, (i) the positioning work of the tool rest when assembling the tool rest can be easily performed;

(ii) Position correction work after installing the turret can be eliminated.

(iii) Since the upper and lower turrets are stored in the rearrangement table and transported together, it is possible to increase work efficiency and improve safety.

(iv) It is also possible to prepare a plurality of reassembly tables and keep the reassembly table in which the turret with a new cutter attached is stored on standby, thereby shortening the waiting time.

(v) With (i) to (iv), blades can be replaced easily, quickly, safely, and reliably.

(vi) Since the upper and lower turrets can be stored separately on the reassembly table, it is possible to carry out the upper and lower turrets individually.
It is possible and convenient to carry it in.

(vii) Since the structure is simple and the number of parts is small, it can be manufactured easily and inexpensively, and maintenance is easy with few breakdowns.

It can produce excellent effects such as
