Description

Technical Field

[0001] The invention relates to the technical field of connecting rod cutting equipment, in particular to a connecting rod cutting device for an automobile seat cushion buffer. Background Art

[0002] The car spring buffer is used to be installed on the coil spring of the car suspension system. It mainly plays a role in buffering and shock absorption and protecting the shock absorber. The car buffer uses the hydraulic spring shock absorption function. When the cars collide instantly, the buffer plays a buffering role to reduce the degree of damage after the collision between the two cars and improve the safety of the car and people. The connecting rod in the car seat cushion buffer needs to be cut according to the required size before use.

[0003] The existing cutting equipment for connecting rods of automobile seat cushion buffers requires workers to first take the materials from a distance during the loading process, and then manually insert the connecting rods into the cutting and fixing them, which is extremely inconvenient. In addition, manual loading is not only dangerous, but also consumes manual labor and has low work efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a car seat cushion buffer connecting rod cutting device which has high integration and can effectively improve work efficiency and safety.
