Embodiment

[0023] The invention discloses a stamping auxiliary tool for processing high-precision convex parts, such as Figure 1 to Figure 4 As shown, it includes a first stamping die 1, a second stamping die 2 and an auxiliary tool 3. The auxiliary tool 3 is provided with a concave part adapted to the shape of the workpiece convex part 4, and the end of the first stamping die 1 is in contact with the workpiece convex part. The shape of the end of the second stamping die 2 is adapted to the shape of the end, and the end of the second stamping die 2 is provided with a retractable briquetting block 21. After the briquetting block 21 is shortened, the overall shape of the second stamping die 2 is adapted to the shape of the convex part 4 of the workpiece; The first stamping die 1 , the second stamping die 2 and the auxiliary tool 3 are all provided with a heating device 5 .

[0024] In this embodiment, the recessed portion includes a bottom surface 31, a slope 32 and a surface 33; a rounde...

Abstract

The invention discloses a stamping auxiliary device capable of machining a high-precision protrusion part. The stamping auxiliary device comprises a first stamping die, a second stamping die and an auxiliary device body; a sinking part matched with the workpiece protrusion part in shape is formed in the auxiliary device body, the end of the fist stamping die and the end of the workpiece protrusion part are matched in shape, a telescopic pressing block is arranged at the end of the second stamping die, after the pressing block is shortened, the whole shape of the second stamping die is matched with the shape of the workpiece protrusion part, and the first stamping die, the second stamping die and the auxiliary device body are each provided with a heating device. The dies and the workpiece can be heated, after the workpiece is heated, the workpiece is more easily stretched evenly, stamping precision is ensured, deformation is not prone to generation, after the workpiece is stamped, the workpiece is attached to the auxiliary device body, and the high-precision requirement of the workpiece protrusion part an be ensured.

Description

technical field [0001] The invention relates to the technical field of sheet metal parts processing, in particular to a stamping auxiliary tool for processing high-precision convex parts. Background technique [0002] Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in electronic appliances, communications, automobile industry, medical equipment and other fields. [0003] At present, in the processing of sheet metal, plane stamping has been able to meet extremely high precision requirements, but for direct stamping of convex parts, its high precision cannot be guaranteed. Contents of the invention [0004] The purpose of the invention: the invention discloses a stamping auxiliary tool for processing high-precision convex parts, which can heat the mold and the workpiece, and the workpiece is easier to be stretched ev...
