Description

Technical Field

[0001] The utility model relates to the technical field of automobile lower swing arms, in particular to a punching device for automobile lower swing arms. Background Art

[0002] The lower arm of a car is an important component in the car suspension system. It is also called the lower control arm or lower suspension arm. It connects the frame or body to the lower part of the wheel assembly and plays the role of supporting the wheel, fixing the wheel position and controlling the wheel movement. The lower arm is usually made of metal materials such as steel or aluminum alloy to provide sufficient strength and rigidity. Their shape and structure vary depending on the model and suspension system design. When punching the lower arm of a car, punching equipment is required.

[0003] After searching, it was found that there are automobile lower arm punching equipment in the prior art, such as an automobile lower arm punching equipment disclosed in publication number CN218744288U. By arranging a clamping component on the base, the shaking of the lower arm can be greatly reduced. When the lower arm is in a stable state, a better hole position can be formed when punching, which can improve the punching quality. When the lower arm is clamped, the spring will be energized and can quickly clamp the lower arm, effectively improving the stability of the lower arm during stamping.

[0004] The existing automobile lower arm punching equipment mainly clamps it through a clamping component when punching. The clamping force of the clamping component is relatively small. Due to the large extrusion force of the stamping equipment, the clamping component is easy to loosen during use, causing the automobile lower arm to move, affecting the punching quality of the automobile lower arm. For this reason, we propose a automobile lower arm punching equipment. Utility Model Content
