Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

When working, the cylinder 2 is started, the cylinder 2 drives the connecting plate 3 to move downward, and the connecting plate 3 drives the upper mold 4 to impact the material on the lower mold 5, thereby completing the stamping of the material.

[0024] In the process of stamping the material, the material is first placed on the lower die 5 manually. The accuracy of the material position cannot be guaranteed during placement. In order to position the material, a positioning mechanism 7 is provided on the lower die 5.

During operation, after the material is manually placed on the lower mold 5, the positioning mechanism 7 is started, and the first motor 72 is started. The first motor 72 drives the bidirectional screw rod 71 to rotate, and the bidirectional screw rod 71 drives the two first screw sleeves 73 to move toward each other. The two first screw sleeves 73 drive the two positioning plates 74 to move toward each other, so as to clamp and position the material to be processed. The first sliding rod 75 and the sliding sleeve 76 guide the positioning plate 74, so that the movement of the positioning plate 74 is more stable.

[0025] When stamping the material, due to the large impact force and fast impact speed, the material will bounce up when stamping the material, and then be pressed again after bouncing, resulting in deformation of the stamped parts. In order to reduce the occurrence of this situation, a fixing mechanism 8 is provided on the positioning plate 74, such as Figure 4 As shown, a first mounting groove 741 is provided on one side opposite to the two positioning plates 74, and the fixing mechanism 8 includes an electric telescopic rod 81 and a pressing plate 82. The electric telescopic rod 81 is fixedly connected to the bottom wall of the first mounting groove 741, and the output end of the electric telescopic rod 81 is fixedly connected to the pressing plate 82, and the pressing plate 82 is slidably connected to the first mounting groove 741. After the positioning mechanism 7 positions the material, the fixing mechanism 8 is started to fix the material, and the electric telescopic rod 81 is started, and the electric telescopic rod 81 drives the pressing plate 82 to move downward and press on the material to be processed, thereby fixing the material.

[0026] like Figure 2 , Figure 5 and Figure 6As shown, in order to facilitate demoulding, an ejection mechanism 9 is provided in the lower mold 5, a third groove 53 is provided in the lower mold 5, a limiting groove 54 is provided above the third groove 53, the limiting groove 54 is connected with the third groove 53 and the outside, and the ejection mechanism 9 includes a screw rod 91, a second motor 92, a moving block 93, a protrusion 94, a second slide bar 95, an ejection block 96, and a protective pad 97. One end of the screw rod 91 is rotatably connected to the third groove 53, and the other end is fixedly connected to the output end of the second motor 92. The second motor 92 is fixedly connected in the third groove 53, and the second slide bar 95 is fixedly connected to the third groove 53. A threaded through hole is provided on one side of the moving block 93, and a smooth through hole is provided on the other side. The threaded through hole of the moving block 93 is sleeved on the screw rod 91, and the smooth through hole is sleeved on the second slide rod 95. The moving block 93 is threadedly connected to the screw rod 91 and is slidably connected to the second slide rod 95. The moving block 93 is fixedly connected with a protrusion 94 near the upper part of the screw rod 91. The protrusion 94 is semicircular, and the limiting groove 54 is provided above the screw rod 91. An ejection block 96 is provided in the limiting groove 54. The ejection block 96 is slidably connected to the limiting groove 54. The top of the ejection block 96 is wedge-shaped, and the top of the ejection block 96 is fixedly connected with a protective pad 97. When the material is stamped and needs to be demoulded, the ejection mechanism 9 is started, the second motor 92 is started, the second motor 92 drives the screw rod 91 to rotate, the screw rod 91 drives the moving block 93 to move, the moving block 93 drives the upper protrusion 94 to move, the protrusion 94 moves to the ejection block 96, and pushes the ejection block 96 to move upward along the trajectory of the protrusion 94 to eject the stamping material from the mold. Since the top of the ejection block 96 is wedge-shaped, it is convenient for the stamping material to tilt and fall. Then, as the protrusion 94 continues to move, the ejection block 96 falls back into the limit groove 54 along the trajectory of the protrusion 94. When the ejection mechanism 9 is started next time, the second motor 92 is started to reverse, so that the protrusion 94 moves in the opposite direction for demoulding.

[0027] In order to make the stamping equipment safer and prevent waste from splashing during high-pressure impact, the stamping process is designed as a sealed structure. The front and rear sides of the fixed frame 1 opposite to the lower die 5 are fixedly connected with a front fixed plate 10 and a rear fixed plate 11, and the front moving plate 12 and the rear moving plate 13 are fixedly connected to the position opposite to the front fixed plate 10 and the rear fixed plate 11 on the connecting plate 3. Figure 7As shown, a second mounting groove 15 is provided at the top of the front fixed plate 10 and the rear fixed plate 11. The size of the second mounting groove 15 is larger than the front movable plate 12 and the rear movable plate 13, so that the front movable plate 12 and the rear movable plate 13 can be inserted into the second mounting groove 15. A shock absorbing mechanism 14 is provided in the second mounting groove 15. The shock absorbing mechanism 14 includes a plurality of dampers 141 fixedly connected to the bottom wall of the second mounting groove 15. The other ends of the plurality of dampers 141 are fixedly connected to the bearing plate 143. A spring 142 is provided on the outer sleeve of the damper 141. When the material is stamped, the cylinder 2 drives the upper die 4 to impact downward. At this time, the cylinder 2 drives the connecting plate 3 to move downward, and the connecting plate 3 drives the front movable plate 12 and the rear movable plate 13 to move downward and insert into the second groove 15 in the front fixed plate 10 and the rear fixed plate 11, and abut against the shock absorbing mechanism 14. Then the upper die 4 continues to impact the material on the lower die 5 downward to complete the stamping and forming of the material. The stamping and forming process of the material is completed in a closed environment, which can prevent waste from splashing during high-pressure impact, which is safer, and the waste falls to the bottom of the mounting frame 1, which is convenient for collection and cleaning; at the same time, because the front movable plate 12 and the rear movable plate 13 first contact the shock absorbing mechanism 14 during the stamping process, the impact force is buffered, preventing the impact from being too fast and too large to cause damage to the stamping material and the mold, thereby extending the service life of the mold.

[0028] Two avoidance portions 16 are provided on the connection plate 3 at positions opposite to the two positioning plates 74 and the pressure plate 82 , and a collecting door 17 is provided on the front fixing plate 10 , and the waste inside can be collected and cleaned by opening the collecting door 17 .

[0029] The working principle of the utility model is as follows: when the device is stamping the material, the material is manually placed on the lower die 5, the positioning mechanism 7 is started, the two positioning plates 74 are moved toward each other, so as to clamp and position the material to be processed, and then the electric telescopic rod 81 of the fixing mechanism 8 is started, the electric telescopic rod 81 drives the pressing plate 82 to move downward and press on the material to be processed, so as to fix the material, and then the cylinder 2 is started, the cylinder 2 drives the connecting plate 3 to move downward, the connecting plate 3 drives the front moving plate 12 and the rear moving plate 13 to move downward and insert into the second groove 15 in the front fixing plate 10 and the rear fixing plate 11 and abut against the shock absorbing mechanism 14, at this time a closed environment is formed, and then the upper die 4 continues to impact the material on the lower die 5 downward to complete the stamping and forming of the material, and the material is completed. After completion, the cylinder 2 drives the upper die 4 to rise. Due to the setting of the fixing mechanism 8, the upper die 4 can be easily separated from the stamping material. Then, the electric telescopic rod 81 of the fixing mechanism 8 is started to drive the pressing plate 82 to rise and leave the stamping material, and then the first motor 72 of the positioning mechanism 7 is started to reverse, so that the positioning plate 74 is away from the stamping material. Then, the second motor 92 of the ejection mechanism 9 is started to drive the protrusion 94 to move, and the protrusion 94 moves to the ejection block 96, pushing the ejection block 96 to move upward along the trajectory of the protrusion 94, and the stamping material is ejected and demolded. Since the top of the ejection block 96 is wedge-shaped, it is convenient for the stamping material to tilt and fall. Then, as the protrusion 94 continues to move, the ejection block 96 falls back into the limit groove 54 along the trajectory of the protrusion 94, and then the stamping material can be taken out.
