The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] A cold heading die, comprising a support frame 1, a fixing assembly 2 is arranged inside the support frame 1, a limit plate 3 is symmetrically arranged on the left and right sides of the inner side of the support frame 1, and a limit hole 4 is symmetrically arranged on the front and back sides of the base surface of the limit plate 3, and a die 5 is arranged at the bottom of the support frame 1;

[0026] In this embodiment, please refer to Figure 2The fixing assembly 2 includes a fixing plate 201, an electric telescopic rod 202 is arranged at the bottom of the fixing plate 201, a rotating seat 203 is arranged at the driving end of the electric telescopic rod 202 through the fixing plate 201, a first rotating rod 204 is arranged for rotation on the left side of the rotating seat 203, and a second rotating rod 205 is arranged for rotation on the right side of the rotating seat 203, a fixing block 206 is arranged on the outer side of the bottom of the first rotating rod 204 and the second rotating rod 205, a first limiting column 207 is symmetrically arranged on the left side of the base surface of the fixing plate 201, and the fixing plate A second limiting column 208 is symmetrically arranged on the front and back right side of the base surface 201, a first rotating block 209 is arranged on the base surface of the fixed plate 201 and on the right side of the first limiting column 207, a second rotating block 210 is arranged on the base surface of the fixed plate 201 and on the left side of the second limiting column 208, a first connecting rod 211 is rotatably arranged between the front and back sides of the front and back sides of the first rotating block 209 and the first rotating rod 204, and a second connecting rod 212 is rotatably arranged between the front and back sides of the front and back sides of the second rotating block 210 and the second rotating rod 205.

[0027] Among them, the limiting hole 4 is respectively adapted to the first limiting column 207 and the second limiting column 208, so that the first limiting column 207 and the second limiting column 208 can enter the interior of the limiting hole 4 respectively. The support frame 1 is arranged in a "U"-shaped structure, and the fixed plate 201 is arranged inside the support frame 1. The base surface of the fixed plate 201 is provided with a through groove corresponding to the electric telescopic rod 202. The limiting plate 3 is rotatably connected to the support frame 1 through a hinge. By arranging a fixing component 2 on the cold heading mold, the electric telescopic rod 202 can drive the rotating seat 203 to move downward. When the rotating seat 203 moves downward, the first rotating rod 204 and the second rotating rod 205 rotate upward, so that the fixed block 206 can move upward, and the support frame 1 is moved upward.

[0028] The working process of the utility model is as follows: when using the cold heading die, first install the fixed plate 201 at a suitable position. When the die 5 is worn and needs to be replaced, operate the electric telescopic rod 202. The electric telescopic rod 202 drives the rotating seat 203 to move downward during operation. With the cooperation of the first connecting rod 211 and the second connecting rod 212, when the rotating seat 203 moves downward, the first rotating rod 204 and the second rotating rod 205 rotate upward. At this time, the fixed block 206 is away from the upper side of the limiting plate 3, and the support frame 1 is moved upward. When the limiting hole 4 moves to the outside of the first limiting column 207 and the second limiting column 208, the limiting plate 3 is rotated to both sides respectively. When moving downward, the support frame 1 can remove the die 5 from the fixed plate 201, thereby facilitating the replacement of the die 5. It is more convenient to replace it, so that it can be better processed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
