Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a punching machine with a positioning tool for fender processing. Background Art

[0002] Punching machines with positioning tools for fender processing are usually used to achieve efficient mass production while ensuring the quality and precision of parts. Such punching machines are usually equipped with some specific positioning tools, such as fixtures, dies, and gauges, to ensure that the fender can be accurately positioned and clamped during the stamping process.

[0003] The existing patent number CN217528993U discloses a punch press with positioning tooling for fender processing, including a base; a first inverted L-shaped plate is fixed on the base; a hydraulic cylinder is fixedly connected to the top of the first inverted L-shaped plate, and a hydraulic rod is provided at the output end of the hydraulic cylinder, and a stamping die plate is fixedly connected to the bottom end of the hydraulic rod; a concave groove is provided on the top of the base; a concave plate is slidably connected to the bottom of the concave groove; a first cavity is provided in the concave plate; a second inverted L-shaped plate is fixedly connected to the bottom end of the first cavity through a spring, and the top end of the second inverted L-shaped plate extends out of the concave plate; this is to solve the problem that when the stamping die is pressed down due to the lack of a fixing mechanism in the stamping, the plate is easily affected by the external environment and the position is offset, resulting in poor stamping quality of the fender, and the placement position is not accurate enough, affecting the stamping size of the fender.

[0004] In the prior art, each time stamping is performed, the T-shaped column needs to be pulled to fix the plate in the box, which is suitable for single stamping. However, during continuous stamping, repeated manual operations affect the processing speed and the stamping efficiency. Utility Model Content
