Thread abrasion prevention pressing block for brake shoe automatic riveting equipment

Abstract

The invention relates to a thread abrasion prevention pressing block for brake shoe automatic riveting equipment. The thread abrasion prevention pressing block is prepared from, by weight, 15-18 parts of polyethylene resin, 10-28 parts of organic silicon resin, 16-25 parts of furan resin, 3-5 parts of alkylphenol polyoxyethylene, 1-2 parts of polyoxyethylene lauryl ether, 6-8 parts of ammonium bicarbonate, 12-18 parts of aluminum oxide, 16-28 parts of graphite, 7-14 parts of molybdenum dioxide and 12-14 parts of calcium carbonate. The thread abrasion prevention pressing block produced according to the matching ratio is quite small in abrasion coefficient and not prone to abrasion in the long-time using process, so that looseness and displacement phenomena are avoided in the riveting process, and the probability that waste and degraded products are produced in the machining process is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile processing parts, in particular to an anti-slip wire briquetting block of automatic riveting equipment for brake shoes. Background technique [0002] In the prior art, the anti-slip wire press block of the automatic riveting equipment for automobile brake shoes is under stress for a long time during use, and is easily subject to wear and tear, resulting in loosening and displacement during the riveting process, thereby preventing slipping The silk effect becomes worse, the processing degree is not complete, and the probability of waste and defective products increases. Contents of the invention [0003] According to the deficiencies of the prior art, the present invention provides an anti-slip wire pressing block of an automatic riveting equipment for brake shoes that is not easy to wear. [0004] The present invention is achieved in this way. The anti-skid wire briquetting block of automati...
