Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 5 As shown, this embodiment proposes a punching machine for manufacturing bolts, including a punching machine body 1, a slide rail 2 is fixedly connected to the bottom end of the inner side of the punching machine body 1, a movable seat 3 is slidably connected to the slide rail 2, a mold seat 4 for placing a workpiece is fixedly connected to the top of the movable seat 3, a punching mechanism 5 for punching the workpiece is arranged at the top end of the inner side of the punching machine body 1, a demoulding mechanism 8 is arranged at the bottom of the movable seat 3, the demoulding mechanism 8 includes a push rod 81 penetrating the movable seat 3, the push rod 81 is slidably connected to the movable seat 3, a guide groove corresponding to the push rod 81 is opened on the inner side of the movable seat 3, and the push rod 81 slides with the guide groove The top of the ejector rod 81 is fixedly connected to a ejector plate 82, which is located on the inner side of the die seat 4 and the top wall of the ejector plate 82 contacts the bottom wall of the workpiece. The bottom of the ejector rod 81 is fixedly connected to a mounting seat 83, and the inner side of the mounting seat 83 is rotatably connected to a roller 84. One end of the punch body 1 is fixedly connected to a ejector block 7, and the roller 84 can contact the ejector block 7 by translation. A spring 85 is sleeved on the ejector rod 81, and the top end of the spring 85 contacts the bottom wall of the movable seat 3, and the bottom end of the spring 85 contacts the mounting seat 83. A translation mechanism 6 for driving the movable seat 3 to translate is provided at one end of the inner side of the punch body 1.

[0024] By placing the workpiece in the mold base 4, and then punching the workpiece into shape through the stamping mechanism 5, and then driving the movable seat 3 to slide along the slide rail 2 through the translation mechanism 6, the mold base 4 and the stamping mechanism 5 are misaligned, which makes the roller 84 roll. When the roller 84 contacts the top block 7, the roller 84 is squeezed by the top block 7 and moves upward, which makes the top plate 82 slide upward, so that the top plate 82 in the mold base 4 pushes out the formed workpiece, so that the workpiece can be taken out directly without overcoming the friction between the workpiece and the inner wall of the mold cavity of the mold base 4, which greatly reduces the difficulty of mold removal and improves work efficiency.

[0025] Furthermore, the punching mechanism 5 includes a cylinder 51, which is fixedly connected to the top of the inner side of the punching machine body 1, and the output end of the cylinder 51 is fixedly connected to a mounting plate 52, and the bottom of the mounting plate 52 is fixedly connected to a punching head 53. By controlling the cylinder 51 to make the mounting plate 52 translate downward, the punching head 53 is in contact with the workpiece in the die seat 4 and the workpiece is punched and formed.

[0026] Furthermore, the translation mechanism 6 includes a rotating shaft 61, one end of which is rotatably connected to the movable seat 3, the other end of which is fixedly connected to a traveling gear 62, a toothed plate 63 meshing with the traveling gear 62 is fixedly connected to the inner side of the punch body 1, and a driving member 64 for driving the traveling gear 62 to rotate is provided at one end of the punch body 1. The traveling gear 62 is driven to rotate by the driving member 64, so that the traveling gear 62 rolls along the toothed plate 63, and the rotating shaft 61 drives the movable seat 3 to slide along the slide rail 2, thereby realizing the overall translation of the movable seat 3.

[0027] Furthermore, the driving member 64 includes a motor 641, which is fixedly installed at one end of the punch body 1. The output shaft of the motor 641 is fixedly connected to a worm 642. A worm wheel 643 is coaxially fixedly connected to one side of the traveling gear 62. The worm wheel 643 is meshed with the worm 642. The length of the worm 642 is the same as the length of the tooth plate 63, and the worm 642 is arranged parallel to the tooth plate 63.

[0028] Working principle: by placing the workpiece in the mold base 4, and then punching the workpiece into shape through the stamping mechanism 5, and then starting the motor 641 to rotate, the worm 642 rotates, which makes the worm wheel 643 drive the travel gear 62 to rotate, so that the travel gear 62 rolls along the tooth plate 63, and the rotating shaft 61 drives the movable seat 3 to slide along the slide rail 2, which makes the mold base 4 and the stamping mechanism 5 misaligned, and the roller 84 rolls. When the roller 84 conflicts with the top block 7, the roller 84 is squeezed by the top block 7 and moves upward, which makes the top plate 82 slide upward, so that the top plate 82 in the mold base 4 pushes out the formed workpiece, so that the workpiece can be taken out directly, and there is no need to overcome the friction between the workpiece and the inner wall of the cavity of the mold base 4 to take it out, which greatly reduces the difficulty of mold removal and improves work efficiency.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
