Description

Vehicle rolling parts processing equipment{PROCESSING APPARATUS OF ROLLING COMPONENT FOR VEHICLE}

The present invention relates to an apparatus for processing rolling parts for vehicles, and more specifically, rolling parts for vehicles with improved precision while simply manufacturing rolling parts that are installed so as to buffer interference between parts joined among parts of a vehicle, sound absorption of the seal, and act on friction. It relates to a parts processing device.

In general, rolling parts are manufactured by wood processing or press die processing, and when using a wooden die, the height of the blade of the wooden die must be high, and there is difficulty in taking it out from the die after processing.Non-woven fabric, wool, rubber, etc. are tough due to the characteristics of the material of the rolling component. Since it is higher than this sponge, it is difficult to process due to lower extrusion rate.

In addition, because of the characteristics of the material, not only the cutting operation is not possible with the pressing force of the wood mold that is processed in general, and the wood mold structurally cannot produce a blade with a single line. Therefore, processing a tough material shortens the life of the wood mold and reduces the product of the rolling parts. Since a lot of bridges of scrap remain, post-processing is necessary.

In addition, if punching is performed using a mechanical, hydraulic, or press mold in mold processing, the outer peripheral surface of the rolling part becomes concave to the inner center, resulting in poor quality and impossible to use.In addition, the gap between products due to the characteristics of the press mold during the production of rolling products There is a problem in that the yield of raw materials is lowered as it is required to be large.
