Description

Technical Field

[0001] The utility model relates to the technical field of leaf spring trimming, in particular to a novel leaf spring stamping and trimming mechanism. Background Art

[0002] Automobile leaf springs are elastic elements in vehicle suspension systems. They are typically composed of several sheets of alloy spring steel of unequal lengths, forming a spring beam of approximately equal strength. During processing, the ends of the leaf springs must be punched and trimmed to obtain the desired steel strip dimensions. Chinese Patent Publication No. CN213997431U discloses a leaf spring end stamping and trimming device, comprising a stamping and trimming machine body and a C-shaped trimming head positioned below the stamping section of the machine body. The trimming head houses a cylindrical punching head. A support ring is fixed to the bottom of the stamping section of the machine body, and the stamping section of the machine body is covered by a transparent, sliding cover.

Then the steel bars are pulled out and the operation is repeated. Since it is necessary to wait for the previous set of steel bars to be pulled out and the stamping end to be reset, the loading and unloading time is long, resulting in low processing efficiency.
