Small steel wheel balance blocks, manufacturing method thereof and stamping die

Abstract

The invention disclose small steel wheel balance blocks and a strip-shaped wheel balance block, a method for producing the small steel wheel balance blocks and a stamping die. Each small steel balance block is provided with a lower bottom surface which can be adhered to a double-faced adhesive tape; each small steel wheel balance block has a wholly press-formed integrated structure and uniform blanking sections without collapsed corners. A plurality of small steel wheel balance blocks are adhered to one side the double-faced adhesive tape to form the strip-shaped wheel balance block. The stamping die for producing the small wheel balance blocks comprises a feed section, a stamping section and a positioning section; the stamping section and the positioning section have the same length in the feed directions, so that after steel plate blank is blanked, the small steel wheel balance blocks with the same quality can be obtained on the stamping section and the positioning section of the stamping die simultaneously. According to the technical scheme, the energy consumption of production can be reduced obviously, the produced product is good in appearance, and high production efficiency is guaranteed.

Description

technical field [0001] The invention relates to a small steel wheel balance block and a strip-shaped wheel balance block, as well as a stamping die for producing the steel wheel balance block and a production method for the steel wheel balance block. Background technique [0002] At present, there are two types of balance weights for automobile wheels at home and abroad: the external hanging type and the built-in pasting type. The external wheel balance weight has the advantages of easy assembly and disassembly, but it requires that the wheel hub must have a flange to facilitate the external balance weight, which has a certain impact on the appearance of the car wheel. On the other hand, there is also a risk of falling off, which is prone to safe question. In recent years, with the large-scale use of automobile aluminum alloy wheels and the strict requirements on the appearance of automobiles, high-end automobiles and even ordinary family automobiles have also adopted built...

AI Technical Summary

Problems solved by technology

Since the scissors formed by the upper blade and the lower blade are all stressed on one side, the punching section and the upper and lower bottom surfaces of the workpiece will be inclined at a certain angle when the workpiece is cut, that is, the punching section and the upper and lower bottom surfaces of the workpiece will be inclined at a certain angle. It is no longer perpendicular to each other, which causes a large collapse angle on the shear section of the workpiece to be cut, and with the wear of the cutting blade edge, the collapse angle will become larger and larger, seriously affecting the section quality of the part
