Description

Technical Field

[0001] The utility model relates to the technical field related to the production of stepped shaft parts, in particular to an integrally formed extrusion die for stepped shaft parts. Background Art

[0002] The forming processes commonly used for shaft parts include die forging, free forging, extrusion, etc., so a mold is required for extrusion forming. However, the existing one-piece extrusion mold for stepped shaft parts still has certain defects when used, such as;

[0003] For example, a hot extrusion die for a stepped shaft with publication number CN216502150U supports and fixes the device through a base, and a bracket supports and fixes the hydraulic cylinder. The two semicircular dies are relatively fitted and installed on a mounting seat, and the upper die is fixed to the top of the two semicircular dies by bolts, and then the two clamping mechanisms are tightened to clamp the two semicircular dies relatively, and then the workpiece is placed inside the upper die, and then the hydraulic cylinder is started to drive the push plate to move downward along the inside of the bracket, driving the forging block to continuously forge the workpiece, and making the bottom of the workpiece gradually enter the mold cavity of the two semicircular dies for forming, and in the process of the push plate movement, it will drive the water flow inside the water cooling component to circulate according to its frequency, so that the device has the advantages of meeting the cooling requirements of the mold while avoiding excessive cooling of the workpiece, ensuring the forging effect, and having a better and more stable fixing effect on the left and right molds.

[0004] However, the hot extrusion die for stepped shafts still has the following disadvantages in actual use:

[0005] The upper mold is fixed by bolts, and the two clamping mechanisms are tightened to clamp the two semicircular molds relatively. In actual use, not only may the bolts become loose, which easily leads to a decrease in the stability of the mold, but also manual operation is required, which reduces the overall production efficiency. In addition, when the clamping mechanism is fixed and clamped, the operator is required to perform precise adjustments and tightening, which increases the complexity of the operation and easily affects the accuracy and service life of the mold.

[0006] In view of the above problems, it is urgently necessary to carry out innovative design based on the original one-piece extrusion die of the stepped shaft. Therefore, we proposed that the one-piece extrusion die of the stepped shaft can well solve the above problems. Utility Model Content
