[0002] The engine rocker arm is an important part of the engine intake and exhaust system. During the operation of the engine, in order to maintain the normal operation of the engine, the rocker arm has to bear high-speed alternating loads and impact loads for a long time. The reliability and durability of the rocker arm have always been a concern of automotive workers, requiring the valve rocker arm to have high strength, wear resistance and heat resistance. Among them, the wear resistance of the rocker arm is not only related to the service life of the valve rocker arm, but also closely related to the power performance, economy and noise of the engine.

[0003] The existing engine rocker arm is generally made of a whole piece of steel through multiple separate processes, and each process requires the engine rocker arm to be repositioned. It not only has cumbersome processing procedures and high production costs, but also has low processing efficiency and poor processing accuracy. Utility Model Content

[0007] Furthermore, the rear end of the material belt is connected to an external driving mechanism which can drive the material belt to move horizontally and intermittently.

[0008] Furthermore, the distance between two adjacent processing stations is an integer multiple of the single moving distance of the material strip, and when the material strip stops moving, the processing tools on the upper die base and the lower die base perform mold closing processing on the material strip.

[0009] Furthermore, the several processing stations are respectively the trimming and positioning hole processing station, the shape processing station, the bending processing station, the bow height and ball socket processing station, the square hole processing station, the side punching round hole processing station, the chamfering processing station, the injection hole processing station and the material strip cutting processing station.

[0011] Furthermore, a nitrogen spring is provided on the lower die seat to facilitate the resetting of the upper die seat and the lower die seat.

[0012] The beneficial effects of the utility model are:

[0013] This solution arranges several processing stations in sequence between the upper mold base and the lower mold base, so that each time the upper mold base and the lower mold base are closed, several processing stations can respectively perform a closing process on the workpieces at different positions on the material strip, thereby realizing multi-process synchronous staggered processing of several workpieces on the material strip, thereby improving the processing efficiency of the engine rocker arm.
