Description

Technical Field

[0001] The utility model relates to the technical field of dust cover production, in particular to a double-station synchronous processing device for a shock absorber dust cover. Background Art

[0002] The dust cover can prevent dust, moisture and other impurities from entering the interior of the equipment, thereby protecting the performance and life of the equipment. The shock absorber dust cover is a protective part that prevents road dust, splashing mud, etc. from entering the shock absorber and causing damage to related parts. It has an important impact on the reliability of the shock absorber. With the increase in automobile production, the demand for shock absorber dust covers is also increasing year by year.

[0003] Most of the existing shock absorber dust covers are stamped. During the production process, one process is equipped with a dedicated stamping equipment. This process uses multiple equipment for processing, which requires a large number of equipment, occupies a large amount of space and consumes a lot of energy, and has low production efficiency. If a single device is used to process by replacing the mold, although the equipment investment and floor space can be reduced, the disassembly and assembly of the mold will consume a lot of time, which will further reduce the production efficiency and cannot meet the production needs.
