[0002] Forging is a processing method that uses hammering or pressurizing of high temperature or room temperature metal to give metal objects a certain shape and size and change their physical properties. During the forging process, the blank is generally clamped and fixed manually with pliers, as shown in the attached figure of the manual. Figure 4 The existing pliers shown include left and right pliers handles hinged together. The user holds the pliers to clamp the blank on the workbench, and forges the blank by moving the forging machine press or hammer head up and down. During the use of the pliers, the user needs to hold the pliers to clamp the blank all the time, which has a high labor intensity. The long-term clamping work makes the user's hands sore and weak, resulting in unstable clamping of the blank or falling off, which poses a certain danger to the user.

[0026] The present invention will be further explained below in conjunction with specific implementation methods.

[0027] like Figure 1-3As shown, the forging fixture for a forging machine provided in this embodiment includes a main frame 1 fixed on a support leg 13, and an adjusting rod 2 is horizontally passed through the center position of the main frame 1; the main frame 1 includes two transverse supporting plates 12 arranged between two longitudinal supporting plates 11, and the two transverse supporting plates 12 are symmetrically arranged about the adjusting rod 2. The middle surface of the adjusting rod 2 body is unthreaded, and threads are respectively arranged on both sides of the middle, and the threads on both sides of the middle of the adjusting rod 2 are respectively screwed to the two longitudinal supporting plates 11. The bottom surfaces of the two longitudinal supporting plates 11 are respectively fixed to the support legs 13, and the support legs 13 are fixed to the ground. The main frame 1 is fixed to the support legs 13, and the support legs 13 are fixed to the ground; the user does not need to hold it, freeing the user's hands, saving effort, and having low labor intensity. The adjusting rod 2 is screwed to the main frame 1 and can move forward and backward relative to the main frame 1.

[0028] In this embodiment, one end of the adjusting rod 2 is axially connected to the first transmission plate 3, and the first transmission plate 3 is axially connected to the middle and rear part of the inner side of the clamp 4. The front part of the clamp 4 clamps the blank, and the opposite surfaces of the front parts of the two clamps 4 are provided with saw teeth 41, which are used to increase the friction force of the opposite surfaces of the clamps, so that the clamps 4 clamp the blank tighter; the clamp 4 is located in the middle part just above the forging table 7, which is convenient for positioning and clamping the blank. The clamp 4 is axially connected to the second transmission plate 5 near the end of the main frame 1, and the second transmission plate 5 is axially connected to the main frame 1. Two clamps 4, the first transmission plate 3, and the second transmission plate 5 are symmetrically arranged about the center line of the adjusting rod 2. A bearing 22 is mounted on one end of the adjusting rod 2, and the bearing 22 is clamped to the connecting plate 23. The connecting plate 23 is axially connected to the two first transmission plates 3; a handwheel 21 is provided at the other end of the adjusting rod 2. The connecting plate 23 is axially connected to the two first transmission plates 3 at the same time.

[0029] The two first transmission pieces 3 are respectively axially connected to the second transmission pieces 5, and the two second transmission pieces 5 are respectively axially connected to the ends of the main frame 1. By rotating the hand wheel 21, the adjusting rod 2 rotates in the bearing 22 and moves forward, pushing the connecting plate 23 to move forward, and the angle between the connecting plate 23 and the two first transmission pieces 3 increases, so that the clamping plates 4 open and move away from each other. The two second transmission pieces 5 rotate outward to assist the first transmission piece 3 to open the clamping plates 4. By rotating the adjusting rod 2 in the opposite direction, the clamping plates 4 close and clamp the blank.

[0030] In this embodiment, the two transverse support plates 12 are both threaded with the clamping members 6, and the two clamping members 6 are symmetrically arranged. An arc plate 61 is arranged at one end of the clamping member 6 located on the inner side of the transverse support plate 12, and a rotating handle 62 is arranged at one end of the clamping member 6 located on the outer side of the transverse support plate 12. The curvature of the inner side of the arc plate 61 is adapted to the middle part of the body of the adjustment rod 2; the inner side surface of the arc plate 61 is evenly provided with trapezoidal protrusions 63. Rotate the rotating handle 62 to make the two arc plates 61 wrap and press against the middle part of the body of the adjustment rod 2. After the position of the adjustment rod 2 is fixed, the clamping member 6 strengthens and fixes the adjustment rod 2 firmly. The inner side surface of the arc plate 61 is evenly provided with trapezoidal protrusions 63, which increases the friction between the clamping member 6 and the adjustment rod 2 and strengthens the fixing effect.

[0031] The working principle of the forging fixture is as follows: first, rotate the adjusting rod 2, the adjusting rod 2 rotates in the bearing 22 and moves forward, pushing the connecting plate 23 connected to the bearing 22 to move forward, the angle between the connecting plate 23 and the two first transmission plates 3 becomes larger, and at the same time, the two second transmission plates 5 follow and rotate outward, assisting the first transmission plate 3 to open the two clamping plates 4 away from each other, that is, the open state. Then place the blank on the forging table between the two clamping plates 4, rotate the adjusting rod 2 in the opposite direction, the clamping plates 4 approach each other, and clamp the blank; finally, rotate the clamping piece 6, so that the two arc plates 61 wrap around and press against the middle of the adjusting rod 2 body, and strengthen the position of the adjusting rod 2, and then use the forging machine press or hammer head to move up and down to forge the blank. The forging clamp is firmly fixed, simple to operate, and has low labor intensity, and solves the problem that the existing pliers need to hold the pliers to clamp the blank all the time during use, which has high labor intensity for users. Long-term clamping work makes the user's hands sore and weak, causing the blank to be clamped unstable or fall off, posing certain dangers to the user.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
