[0025] The following is in conjunction with the appendix Figure 1-8 The present invention is further illustrated by the embodiments:

[0026] A metal stamping machine includes a first vertical plate 1 and a second vertical plate 2. A mounting plate 3 is fixedly disposed between the first vertical plate 1 and the second vertical plate 2. The mounting plate 3 has a clearance groove 4. A stamping plate 5 is placed on the mounting plate 3. The stamping plate 5 has a stamping hole 6. A third vertical plate 99 is disposed on one side of the mounting plate 3. A first hydraulic cylinder 7 is fixedly disposed on the third vertical plate 99. A mounting shell 8 is fixedly disposed on the piston rod of the first hydraulic cylinder 7. A mounting cavity 9 is disposed inside the mounting shell 8. The mounting cavity 9 is open on both sides and at the bottom along the width direction l of the mounting plate 3. A clamping plate 10 is disposed inside the mounting cavity 9. A punching head 188 is fixedly installed at the bottom of the clamping plate 10. A first clamping device for clamping the clamping plate 10 is provided in the mounting cavity 9. A second clamping device for clamping the stamping plate 5 is provided on the mounting plate 3. Support plates 11 are respectively provided on the first upright plate 1 and the second upright plate 2. Two second hydraulic cylinders 12 are fixedly installed on each support plate 11, and the two second hydraulic cylinders 12 are distributed along the width direction of the stamping plate 5. A first pressure plate 13 (used to clamp thin plates during stamping) is fixedly installed on the piston rods of the two second hydraulic cylinders 12. A material discharge groove 13 is placed below the punching hole 6. The metal mechanical stamping equipment also includes an auxiliary installation device.

[0027] The auxiliary installation device includes an electric push rod 30 fixedly mounted on the second upright plate 2. An electric track 31 is fixedly mounted on the moving end of the electric push rod 30. A moving plate 32 is fixedly mounted on the moving end of the electric track 31. A fixed rod 33 and two third hydraulic cylinders 34 are fixedly mounted on the moving plate 32. The fixed rod 33 is located between the two third hydraulic cylinders 34. A fixed plate is fixedly mounted on the upper end of the fixed rod 33.

[0028] A circular disc 36 is fixedly mounted on the piston rod of the two third hydraulic cylinders 34, and the circular disc 36 can reciprocate along the length direction of the fixed rod 33. Six first inclined plates 37 are evenly distributed on the top surface of the circular disc 36 along the circumferential direction. A support disc 38 is fixedly mounted on the top of the fixed rod. Six second inclined plates 39 are evenly distributed on the bottom surface of the support disc 38 along the circumferential direction. The first inclined plates 37 cooperate with the second inclined plates 39. A cylindrical rod 40 is fixedly mounted on each second inclined plate 39.

[0029] When installing the punch head, place the clamping plate 10 into the mounting cavity 9, then activate the first hydraulic cylinder 7 to move the punch head 188 downwards. When the bottom surface of the punch head 188 pushes the moving sleeve 52 downwards, stop the movement of the first hydraulic cylinder 7. Then, the operator adjusts the position of the punch head 188 so that the moving sleeve 52, which is pressed against the bottom surface of the punch head 188, moves away from the bottom surface of the punch head 188. Then, under the reset action of the return spring 53, the moving sleeve 52 will move upwards to the side of the punch head 188. When all the moving sleeves 52 have moved upwards to the side of the punch head 188 (i.e., the outer peripheral wall of the moving sleeve 52 is flush with the outer surface of the punch head 188), the moving sleeve 52 will move upwards to the side of the punch head 188. The circumferential walls are in contact, which means that the centering of the punch head is achieved (because the punch head needs to be able to pass through the punching hole during punching, the diameter of the punch head is slightly smaller than the inner diameter of the punching hole, so that the punch head can move back and forth in the punching hole. Therefore, when the side of the cylindrical rod furthest from the support disc 38 abuts against the inner circumferential wall of the punching hole 6, and because the side of the cylindrical rod abutting against the inner circumferential wall of the punching hole 6 is in contact with the outer circumferential wall of the movable sleeve, all the movable sleeves can just be in contact with the outer circumferential wall of the punch head and move upward. This proves that the punch head installed at this position can just be in the punching hole and move back and forth). Thus, the centering and installation of the punch head and the punching hole are completed.

[0030] A connecting plate 50 is fixedly installed on the outer wall of each cylindrical rod 40. A limiting rod 51 is fixedly installed on the connecting plate 50. A movable sleeve 52 is sleeved on the limiting rod 51. A return spring 53 is fixedly installed between the top of the limiting rod 51 and the top wall of the movable sleeve 52. The movable sleeve 52 is located on the side of the outer peripheral wall of the cylindrical rod 40 furthest from the supporting disc 38, and the outer peripheral wall of the movable sleeve 52 can reciprocate along the outer peripheral wall of the cylindrical rod 40.

[0031] A trapezoidal block 80 is fixedly installed on each second inclined plate 39. A trapezoidal groove 81 is provided on the bottom surface of the supporting disc 38. The trapezoidal block 80 can reciprocate within the trapezoidal groove 81. A travel spring 300 is fixedly installed between the trapezoidal block 80 and the side wall of the trapezoidal groove 81.

[0032] The first clamping device includes a fourth hydraulic cylinder 90 disposed on the side wall of the mounting cavity 9, and a second pressure plate 91 is fixedly disposed on the piston rod of the fourth hydraulic cylinder 90.

[0033] The second clamping device includes clamping assemblies that are respectively fixedly mounted on the first upright plate 1 and the second upright plate 2; the clamping assembly includes a fifth hydraulic cylinder 101 fixedly mounted on the first upright plate 1, and a third pressure plate 95 is fixedly mounted on the piston rod of the fifth hydraulic cylinder 101; the clamping assembly on the second upright plate 2 and the clamping assembly on the first upright plate 1 have the same structure and are symmetrically arranged.

[0034] The outer peripheral walls of the cylindrical rod 40 and the movable sleeve 52 are coated with lubricating oil.

[0035] The working principle of this invention includes the following process:

[0036] When aligning and installing the punching hole and punch head, the operator first places the punch plate 5 on the mounting plate 3, ensuring the punching hole 6 is approximately in the center of the clearance groove 4. Then, the electric push rod 30 is activated to move the cylindrical rod 40 to the center of the clearance groove 4. Next, the electric track 31 is activated, allowing the cylindrical rod 40 to pass through the punching hole 6 and the clearance groove 4. To ensure the cylindrical rod 40 can pass smoothly through the punching hole 6, initially, the outer peripheral wall of the cylindrical rod 40 is close to the outer peripheral wall of the supporting disc 38, thus allowing for a larger gap between the outer peripheral wall of the cylindrical rod 40 and the inner peripheral wall of the clearance groove 4 (e.g., ...). Figure 9 As shown), this facilitates the passage of the cylindrical rod 40, along with the movable sleeve 52, through the punching hole 6. After the cylindrical rod 40 passes through the punching hole 6, the two third hydraulic cylinders 34 are activated to push the annular disk 36 upward. The annular disk 36 then moves the first inclined plate 37 upward, which in turn pushes the second inclined plate 39 away from the center of the supporting disk 38. The second inclined plate 39, along with the cylindrical rod 40, moves together and abuts against the inner circumferential wall of the punching hole 6. When the six cylindrical rods 40 distributed along the circumference simultaneously abut against the inner circumferential wall of the punching hole 6, the punching hole 6 is pushed to the center position. This allows the six cylindrical rods 40 to adjust the center of the punching hole 6 when the operator cannot accurately center it, thus reducing the difficulty for the operator to accurately center the punching hole and improving installation efficiency.

[0037] When installing the punch head, place the clamping plate 10 into the mounting cavity 9, then activate the first hydraulic cylinder 7 to move the punch head 188 downwards. When the bottom surface of the punch head 188 pushes the moving sleeve 52 downwards, stop the movement of the first hydraulic cylinder 7. Then, the operator adjusts the position of the punch head 188 so that the moving sleeve 52, which is pressed against the bottom surface of the punch head 188, moves away from the bottom surface of the punch head 188. Then, under the reset action of the return spring 53, the moving sleeve 52 will move upwards to the side of the punch head 188. When all the moving sleeves 52 have moved upwards to the side of the punch head 188 (i.e., the outer peripheral wall of the moving sleeve 52 is flush with the outer surface of the punch head 188), the moving sleeve 52 will move upwards to the side of the punch head 188. The circumferential walls are in contact, which means that the centering of the punch head is achieved (because the punch head needs to be able to pass through the punching hole during punching, the diameter of the punch head is slightly smaller than the inner diameter of the punching hole, so that the punch head can move back and forth in the punching hole. Therefore, when the side of the cylindrical rod furthest from the support disc 38 abuts against the inner circumferential wall of the punching hole 6, and because the side of the cylindrical rod abutting against the inner circumferential wall of the punching hole 6 is in contact with the outer circumferential wall of the movable sleeve, all the movable sleeves can just be in contact with the outer circumferential wall of the punch head and move upward. This proves that the punch head installed at this position can just be in the punching hole and move back and forth). Thus, the centering and installation of the punch head and the punching hole are completed.

[0038] After adjusting the centering position using the auxiliary installation device, the operator slightly rotates the stamping plate 5, keeping the centering position unchanged, so that the side of the stamping plate 5 facing the third pressure plate 95 is parallel to the third pressure plate 95. This facilitates the activation of the fifth hydraulic cylinder 101, which pushes the two third pressure plates 95 to clamp the stamping plate 5. When the stamping plate 5 is slightly rotated, the cylindrical rod 40 remains within the stamping hole 6, limiting the stamping hole 6 and preventing the centering position from shifting when the stamping plate 5 is rotated. The lubricating oil on the stamping hole 6 reduces the friction between the inner circumferential wall of the stamping hole 6 and the cylindrical rod 40, thus facilitating the adjustment of the position by rotating the stamping plate 5.

[0039] Similarly, by slightly rotating the clamping plate 10, the side of the clamping plate 10 facing the second pressure plate 91 is kept parallel to the second pressure plate 91, thereby activating the fourth hydraulic cylinder 90 and causing the two fourth hydraulic cylinders 90 to clamp the clamping plate 10. At this time, the moving sleeve 52 will still limit the punch head. The lubricating oil on the moving sleeve 52 can reduce the friction with the outer peripheral wall of the punch head, making it easier to rotate the clamping plate 10 to adjust its position.

[0040] After installation, the third hydraulic cylinder 34 is activated first to reset the cylindrical rod 40 and bring it close to the support disc 38 again. Then, the moving plate 32 is activated to move the auxiliary installation device downward. Then, the electric push rod 30 is activated to move the auxiliary installation device away from below the punching hole 6, thereby avoiding interference from the device during the punching operation.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
