Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and specifically to a stamping die forming positioning and material support mechanism. Background Technology

[0002] In stamping processes involving high flanging heights, accurate workpiece positioning and stable support are crucial for ensuring flanging quality. Traditional positioning methods often employ simple locating pins or blocks, which are ill-suited for the positioning requirements of complex-shaped workpieces, easily leading to positioning deviations, insufficient flanging dimensional accuracy, and subsequent assembly problems.

[0003] Meanwhile, the material support process also has significant shortcomings. Existing material support devices often have fixed structures and cannot be flexibly adjusted according to the shape and size of the workpiece. During the flanging process, the workpiece is prone to deformation or shaking due to uneven force, affecting the perpendicularity and surface quality of the flanging. For some thin-walled workpieces, inappropriate material support force may also cause indentations on the workpiece surface, reducing the product qualification rate. In addition, some production processes still rely on manual assistance for positioning and material support, which is not only inefficient and increases labor costs, but also poses significant safety hazards in the high-speed stamping environment.

[0004] Therefore, developing a flanging positioning and material support mechanism that can achieve auxiliary positioning, stable material support, and strong adaptability is of great significance for improving the quality of stamped flanging products, increasing production efficiency, and ensuring production safety. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a stamping die forming positioning and material support mechanism to solve the problems of inaccurate workpiece positioning, unstable material support, poor adaptability, and low efficiency and poor safety caused by reliance on manual assistance in the existing technology during the flanging process. It can achieve accurate positioning and stable support of workpieces of different shapes and sizes, ensure flanging quality, and improve production efficiency.

[0006] The technical solution to achieve the above objective is: a stamping die forming positioning and material support mechanism, comprising a positioning component and a material support component, wherein:

[0007] The positioning assembly includes a positioning base, a lateral positioning block, a cotter pin, and a fixing pin. The bottom end of the lateral positioning block is fixed to one end of the positioning base. The lateral positioning block and the positioning base form an L-shape. A through-groove groove is formed in the middle of the lateral positioning block. A through-groove cotter pin mounting hole is formed in the upper part of the through-groove, and the cotter pin is inserted into the cotter pin mounting hole. The fixing pin is fixed to the lower part of the through-groove.

[0008] The material support assembly includes a contoured material support block and an elastic support member. The contoured material support block is composed of an upper contoured portion, a middle horizontal portion, and a lower vertical portion connected together. The upper contoured portion of the contoured material support block has a pin hole. The upper contoured portion of the contoured material support block is disposed in the receiving groove, and the cotter pin is inserted into the pin hole. The upper end of the upper contoured portion of the contoured material support block extends to the outside of the lateral positioning block to form a supporting boss. The lower vertical portion of the contoured material support block is connected to one end of the elastic support member, and the other end of the elastic support member is connected to the fixing pin.

[0009] In the above-mentioned stamping die forming positioning and material support mechanism, the positioning seat is fixed to the lower die seat of the stamping die by locking bolts.

[0010] In the above-mentioned stamping die forming positioning and material support mechanism, the positioning seat is provided with a locking bolt mounting hole, and the locking bolt is disposed in the locking bolt mounting hole.

[0011] In the above-mentioned stamping die forming and positioning material support mechanism, the elastic support member can be a spring.

[0012] In the above-mentioned stamping die forming and positioning material support mechanism, the shape of the supporting boss of the upper contouring part of the contouring material support block is adapted to the edge shape of the workpiece to be processed.

[0013] The stamping die forming and positioning material support mechanism of this utility model can accurately position and stably support workpieces of different shapes and sizes, ensure the quality of flanging, and improve production efficiency, and has the following beneficial effects:

[0014] (1) To achieve auxiliary positioning of the workpiece to be processed, the lateral positioning block fits against the side of the workpiece to be processed to achieve lateral positioning of the workpiece.
