Description

Chip scrap conveyor

The present invention relates to a chip scrap conveyor for transferring a chip scrap generated during a progressive press mold, and more particularly, the first time that the scrap is generated various chip scrap generated in the progressive mold. It relates to a chip scrap conveyor that can be processed inline from the final process to the chip box.

In general, a press is a general term for an apparatus for forming a product of a certain shape by forcing a material into a mold by using a lever, a screw, a hydraulic pressure, and the like. Such press molds perform extrusion processing, drawing processing, molding, cutting processing, etc., and are classified into manual and power type. The manual type includes a hand press and an eccentric press, and the hydraulic type includes a hydraulic press, a hydraulic press and a mechanical press.

The press is basically a frame type, ram or V type, this frame type has the advantage of having a greater rigidity as a reinforcing casting press, the ram and V type has the advantage of having a greatly reinforced slide surface have.

Conventionally, in addition to products molded in the press as described above, various devices for transferring scrap generated in this product to a separate place have been developed and used, and thus, a great response has not been obtained.

In addition, in a progressive mold in which press processing is carried out while continuously transferring a workpiece from next to next, a large amount of scrap is generated in every processing process, and the scrap generated at this time is very sharp at the end. There was a problem that could not be handled by hand.

In addition, even if a separate transport device is used, a large number of workers were required, and safety accidents occurred frequently, such that workers avoided each other.

Although belt conveyors or chip conveyors are used for the reasons described above, when using belt conveyors, belts are torn by sharp chips or scraps, which easily breaks down, resulting in high installation costs and excessive consumption costs. There was this.

The present invention has been made to solve the above problems, to provide a chip scrap conveyor for improving the durability of the device by easily processing the sharp chip or scrap inline in progressive mold processing. For that purpose.
