Description

Technical Field

[0001] The utility model belongs to the technical field of automobile chassis parts processing equipment, and in particular relates to a semi-automatic trimming machine for an automobile chassis bushing bracket. Background Art

[0002] Automobile chassis bushing bracket parts are common parts in automobile suspension systems. They are usually composed of a lower U-shaped support and an upper circular connector, and are produced by welding or integral casting. In order to reduce the friction loss at the top of the upper circular connector and increase the buffering effect of the bracket, it is necessary to glue the top of the upper circular connector, and the glue is usually applied by hot rubber gluing. Add hot rubber to the circular connector, and after the rubber cools and solidifies, cut off the excess waste edges. The advantage of the hot rubber gluing process is that the rubber and metal parts are tightly connected, and the bonding strength is greatly increased compared to the rubber gluing process.

[0003] The hot rubber gluing process is adopted, and the excess rubber waste edges are cut off after the rubber cools and solidifies. At present, when cutting off the excess rubber waste edges, operators often use scissors and rubber erasers and other auxiliary tools to do the work manually, which not only has low production efficiency, but also causes uneven processing at the outer edge of the bracket, making it difficult to achieve standardized production.
