[0078] As an optional embodiment, the linkage component 6 includes:

[0079] A support frame 31 is fixed on the workbench 1;

[0080] A limiting frame 32 is fixed on the top of the supporting frame 31;

[0081] A threaded rod 33 is disposed inside the limiting frame 32, one end of the threaded rod 33 is rotatably connected to the top of the limiting frame 32, and the other end of the threaded rod 33 is passed through the inside of the supporting frame 31 and is rotatably connected to the supporting frame 31;

[0082] A slider 34 is slidably connected and arranged inside the limit frame 32. The slider 34 is sleeved on the threaded rod 33. The slider 34 is threadedly connected to the threaded rod 33.

[0083] A first connecting rod 35, one end of which is fixedly connected to the slider 34, and the other end of which is fixedly connected to the first pressing plate 9;

[0084] A belt-type synchronous wheel set 36, one of which is arranged inside the support frame 31, the pulley is sleeved on the threaded rod 33 and fixedly connected, and the other pulley is fixedly provided with a gear 37, and the gear 37 is rotatably connected and arranged on the top of the workbench 1;

[0087] For example, the first connecting rod 35 is driven to move by the first pressure plate 9, and the first connecting rod 35 drives the slider 34 to move on the threaded rod 33, so that the slider 34 drives the threaded rod 33 to rotate during the downward movement, and the threaded rod 33 drives the belt synchronous wheel set 36 to work, so that the gear 37 rotates, the gear 37 drives the rack 38 to move, and the rack 38 drives the loading assembly 5 to work to complete the loading work of the clamp straight plate raw material, and the second connecting arm 40 is driven to move by the slider 34, and the second connecting arm 40 drives the slide plate 39 to move, and the slide plate 39 drives the unloading assembly 7 to work to complete the unloading work.

[0088] As an optional embodiment, the feeding assembly 5 includes:

[0089] A limiting slide 41 is fixedly mounted on the top of the workbench 1, and one end of the limiting slide 41 is disposed close to one side of the clamp groove 2;

[0092] For example, a plurality of straight plate raw materials of clamps are placed in the loading frame 42. In the initial stage, the straight plate raw materials of clamps located at the bottom of the loading frame 42 are set inside the limiting slide 41, and the second connecting rod 44 is driven to move by the rack 38. The second connecting rod 44 drives the pushing plate 43 to move, and the pushing plate 43 pushes the straight plate raw materials of clamps in the limiting slide 41 to move into the straight clamp groove 2. At this time, other straight plate raw materials of clamps in the loading frame 42 are blocked by the pushing plate 43 and cannot fall into the limiting slide 41 until the previous straight plate raw material of clamps is processed and formed, and then the pushing plate 43 is reset.

[0098] For example, by making the top surface of the unloading block 46 flush with the bottom of the groove on both sides of the clamp groove 2, the U-shaped part of the clamp groove 2 is filled after the clamp is unloaded, so as to prevent one end of the clamp straight plate raw material from falling into the U-shaped part of the clamp groove 2 during the loading process, resulting in the failure of the clamp workpiece to be stamped and scrapped. During the stamping process of the clamp workpiece, the slide plate 39 drives the limit stop block 47 to move, and the limit stop block 47 drives the unloading block 46 to move into the unloading channel 45 through the linkage rod 48 to release the U-shaped part of the clamp groove 2. After the clamp workpiece is stamped and formed, the slide plate 39 drives the limit stop block 47 to reset, so that the unloading block 46 extends out of the unloading channel 45, pushes out the clamp workpiece, and at the same time, refills the U-shaped part of the clamp groove 2.
