[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: A guide rail type high-speed precision punch press, including a punch bedplate 1, a U-shaped plate 3, a fixed plate 4 and a top plate 5. Both ends of the top of the punch bedplate 1 are provided with fixed plates 4, and the top of the fixed plate 4 is provided with a top plate 5. Electric cylinders 2 are installed at both ends of the top of the punch bedplate 1. Here, the model of the electric cylinder 2 can be J64RT2UNIVER. One end of the bottom of the top plate 5 is provided with a first slide rail 8, and a sliding plate 11 is slidably installed at the bottom of the first slide rail 8. One end of the bottom of the top plate 5 away from the first slide rail 8 is provided with an adjusting screw tube 6, and an adjusting screw 7 is threadedly installed inside the adjusting screw tube 6. One end of the adjusting screw 7 away from the first slide rail 8 is provided with a handle, and a sponge sleeve is installed on the outside of the handle to facilitate the staff to rotate the adjusting screw 7. The bottom of the sliding plate 11 is provided with a U-shaped plate 3, and a motor 19 is installed at one end of the bottom of the U-shaped plate 3 away from the adjusting screw tube 6. Here, the model of the motor 19 can be Y90S-2. Second slide rails 16 are installed at both ends inside the U-shaped plate 3, and a stamping plate 22 is slidably installed on the inner side of the second slide rail 16. A stamping punch 12 is installed at the middle position of the bottom of the stamping plate 22. One end of the punch bedplate 1 away from the adjusting screw tube 6 is provided with a control panel 14. The output end of the control panel 14 is electrically connected to the input ends of the electric cylinder 2 and the motor 19 through wires.

[0023] As Figures 1-4As shown in the figure, a rotating shaft 18 is installed at the output end of the motor 19, and an extrusion bump 17 is installed at one end of the rotating shaft 18 away from the motor 19. A protruding part 23 is arranged on the outer side of the extrusion bump 17. A ball groove 24 is arranged at the middle position of the top of the stamping plate 22, and balls 21 are installed inside the ball groove 24. Both ends of the bottom of the U-shaped plate 3 are installed with bottom plates 15, and return springs 20 are installed on the tops of the bottom plates 15. The ends of the return springs 20 away from the bottom plates 15 are all connected to the stamping plate 22. During use, the motor 19 drives the extrusion bump 17 to rotate uniformly through the rotating shaft 18, so that the protruding part 23 on the extrusion bump 17 can reciprocally extrude the balls 21, driving the stamping plate 22 to reciprocally move, and then the stamping punch 12 can reciprocally punch on the female die. When the protruding part 23 on the extrusion bump 17 rotates to a position away from the balls 21, the extrusion bump 17 no longer extrudes the balls 21. At this time, the elastic action of the return spring 20 makes it push the stamping plate 22 to move upward for reset, so that the balls 21 are closely attached to the outer side of the extrusion bump 17, and the stamping plate 22 drives the stamping punch 12 to move upward together, enabling the stamping punch 12 to move away from the female die, thus completing the automatic processing process.

[0024] As Figure 1 shown, clamping plates 13 are installed at the output ends of the electric cylinders 2. Place the female die to be stamped on the punching machine bedplate 1, and start the two groups of electric cylinders 2 through the control panel 14, so that the electric cylinders 2 push the clamping plates 13 to move, and then the female die can be clamped and fixed by the two groups of clamping plates 13.

[0025] As Figure 1 shown, a bearing 10 is installed at one end of the sliding plate 11 close to the adjusting screw tube 6, and a connecting rotating rod 9 is installed inside the bearing 10. One end of the connecting rotating rod 9 away from the bearing 10 is connected to the adjusting screw 7. During use, by rotating the adjusting screw 7, the adjusting screw 7 moves through the thread, and the adjusting screw 7 drives the sliding plate 11 to move together through the connecting rotating rod 9 and the bearing 10, so as to adjust the position of the stamping punch 12. The adjustment process is relatively convenient, and the device is relatively convenient to use.

[0026] Working principle:

[0027] During use, connect the device to the power supply, then place the female die to be stamped on the punching machine bedplate 1, and start the two groups of electric cylinders 2 through the control panel 14, so that the electric cylinders 2 push the clamping plates 13 to move, and then the female die can be clamped and fixed by the two groups of clamping plates 13;

[0028] The staff can first rotate the adjusting screw 7 clockwise or counterclockwise. The adjusting screw 7 drives the connecting rotating rod 9 to rotate. The connecting rotating rod 9 rotates inside the bearing 10, and the connecting rotating rod 9 will not drive the sliding plate 11 to rotate through the bearing 10;

[0029] Moreover, the adjusting screw rod 7 moves inside the adjusting screw tube 6 through threads. The adjusting screw rod 7 drives the sliding plate 11 to move together through the connecting rotating rod 9 and the bearing 10, so that the position of the stamping punch 12 can be adjusted.

[0030] After the adjustment is completed, stop rotating the adjusting screw rod 7. At this time, the adjusting screw rod 7 is self-locked inside the adjusting screw tube 6 through threads, which can prevent the sliding plate 11 and the stamping punch 12 from continuing to move under the influence of external forces.

[0031] During stamping, the staff can start the motor 19 through the control panel 14, so that the motor 19 drives the extrusion convex block 17 to rotate uniformly through the rotating shaft 18. When the protrusion 23 on the extrusion convex block 17 rotates to contact the ball 21, the extrusion convex block 17 extrudes the ball 21, so that the ball 21 is stressed and pushes the stamping plate 22 downward. The stamping plate 22 extrudes the return spring 20, and the stamping plate 22 drives the stamping punch 12 to move downward together, so that the stamping punch 12 can be stamped onto the female die.

[0032] When the protrusion 23 on the extrusion convex block 17 rotates to a position away from the ball 21, the extrusion convex block 17 no longer extrudes the ball 21. At this time, the elastic action of the return spring 20 makes it push the stamping plate 22 to move upward and reset, so that the ball 21 is closely attached to the outside of the extrusion convex block 17, and the stamping plate 22 drives the stamping punch 12 to move upward together, so that the stamping punch 12 can be separated from the female die.

[0033] Since the motor 19 drives the extrusion convex block 17 to rotate uniformly through the rotating shaft 18, the protrusion 23 on the extrusion convex block 17 can reciprocally extrude the ball 21, so that the stamping punch 12 can reciprocally stamp onto the female die, completing the stamping process of the female die.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
