Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a component for an automotive parts stamping machine. Background Technology

[0002] As the foundation of the automotive industry, auto parts are a necessary factor supporting its continued healthy development. This is especially true given the current vigorous and dynamic independent development and innovation within the automotive sector, which requires a robust parts system. Independent vehicle brands and technological innovation depend on parts as a foundation, while independent innovation in parts, in turn, strongly drives the development of the entire vehicle industry. They are mutually influential and interactive. Without independent vehicle brands, the R&D and innovation capabilities of a strong parts system are difficult to unleash; without the support of a robust parts system, the growth and strengthening of independent brands will be unsustainable. When sheet metal automotive parts are stamped into a "U" shape, the stamped parts are easily stuck in the die cavity and difficult to remove, increasing the difficulty of operation for workers and reducing work efficiency.

[0003] Therefore, it is particularly important to know how to remove the workpiece intact without damaging or scratching its surface. Utility Model Content

[0004] The purpose of this invention is to provide a component for an automotive parts stamping machine to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A component for an automotive parts stamping machine includes a lower die. The top of the lower die has a U-shaped groove that rolls through from front to back. A through-hole is located at the center of the bottom of the U-shaped groove. A slider is disposed inside the through-hole, with its surface transitionally fitting to the interior of the through-hole. The bottom of the slider has a blunted acute-angle structure. The top of the slider is an arc-shaped surface with an arc consistent with the arc of the inner wall of the U-shaped groove. The top of the slider is adapted to the U-shaped groove. A push rod is fixedly mounted on the bottom of the slider. The lower die has a clearance hole for the push rod. The bottom of the lower die has a through-hole rectangular hole, and the bottom end of the push rod is located inside the rectangular hole.

[0006] By adopting the above technical solution, since the slider and the U-shaped groove are essentially one piece with compatible structure and size, when the push rod is pushed upward, the slider will also push the workpiece upward. Because they are one piece, the workpiece will not be scratched. Furthermore, the transition fit between the outer wall of the slider and the receiving groove has a positioning effect, thus avoiding the problem of the slider wobbling.

[0007] In a further embodiment, a force-applying rod is provided inside the rectangular hole, and a left-right rotating shaft passes through the front section of the force-applying rod. Both ends of the rotating shaft are rotatably installed inside the rectangular hole, and a protective sleeve is fitted over the front end of the force-applying rod.

[0008] By adopting the above technical solution, the rear end of the force-applying rod is in contact with the bottom of the top rod, so when the front end of the force-applying rod is pressed down, the top rod can be lifted up.

[0009] In a further embodiment, the rear end of the force-applying rod is provided with a support plate portion.

[0010] By adopting the above technical solution, the support area is expanded, allowing the force-applying rod to better lift the top rod.

[0011] In a further embodiment, the length of the first half of the force-applying rod before the pivot is greater than the length of the second half.

[0012] By adopting the above technical solution, the force-applying rod can be made to work more efficiently.

[0013] In a further embodiment, a cover plate for sealing the rectangular hole is provided at the rear end of the rectangular hole.

[0014] By adopting the above technical solution, foreign objects are prevented from entering the interior of the rectangular hole.

[0015] In summary, this utility model has the following beneficial effects: 1. Because the slider and the U-shaped groove are essentially one piece, with compatible structure and size, when the push rod is pushed upward, the slider will also push the workpiece upward. Since they are one piece, they will not scratch the workpiece. Furthermore, the transition fit between the outer wall of the slider and the receiving groove has a positioning effect, preventing the slider from wobbling. Attached Figure Description
