[0064] A first fixing member is disposed in the upper mold 203 and connected to the mold portion;

[0065] A second fixing member is disposed on the upper mold 203 and abuts against the first adjusting member;

[0066] Figures 1 to 6 As shown, the first fixing member includes:

[0067] A round shell 5 is fixed on the mold part, one end of a second spring 501 is arranged in the round shell 5, a movable block 502 is arranged at the other end of the second spring 501, a convex block 503 is arranged on the movable block 502, a concave plate 504 is arranged in the upper mold 203, and a group of grooves are opened on the concave plate 504, and the grooves are embedded with the convex blocks 503;

[0068] Figures 1 to 6 As shown, the second fixing member includes:

[0069] A threaded block 505 is fixed on the upper mold 203;

[0070] The extrusion bolt 506 is threadedly connected to the thread block 505;

[0071] Specifically, a round shell 5 is installed on the top of the pressing block 302, and one end of the second spring 501 is fixedly connected to the inner side of the bottom wall of the round shell 5, and the other end of the second spring 501 is connected to the movable block 502, and a part of the movable block 502 is located on the inner side of the round shell 5, and a protrusion 503 is installed on the top of the movable block 502, and a concave plate 504 is installed on the inner side of the top wall of the upper mold 203, and a group of grooves are opened at the bottom of the concave plate 504, and one of the grooves is engaged with the protrusion 503, and two threaded blocks 505 are installed on one side of the upper mold 203, and the inner part of the threaded block 505 is threadedly installed with an extrusion bolt 506, and the two extrusion bolts 506 are abutted against the support frame 4.

[0072] In the embodiment of the utility model, the round shell 5 can provide support for the second spring 501 under the fixed support of the pressing block 302, and the round shell 5 can provide a movable space for the second spring 501 and the movable block 502. The second spring 501 can support the movable block 502 by its own elastic force, so that the movable block 502 can provide fixed support for the protrusion 503;

[0073] When the staff needs to adjust the position of the pressing block 302 and the lower module 304, the staff twists the extrusion bolt 506 to make the extrusion bolt 506 move upward under the thread support of the threaded block 505, so that the extrusion bolt 506 no longer abuts against the support frame 4, and the staff moves the pressing block 302 by pulling the adjustment part, so that the pressing block 302 drives the protrusion 503 to move under the action of external force through the round shell 5, the second spring 501 and the movable block 502, so that the protrusion 503 moves downward under the pressure of the groove on the concave plate 504, so that the protrusion 503 is outside. Under the action of force, the movable block 502 is squeezed downward, so that the movable block 502 moves downward along the inner side of the circular shell 5. When the protrusion 503 moves to another groove position, the second spring 501 can use its own elastic force to drive the protrusion 503 to move into the inner side of another groove through the movable block 502, thereby fixing the pressing block 302. The staff then turns the squeezing bolt 506 in the opposite direction to make the squeezing bolt 506 move downward and abut against the support frame 4, thereby fixing the support frame 4, so that the adjusted pressing block 302 and the lower module 304 can be fixed.

[0074] Figures 1 to 6 As shown, the measuring unit includes:

[0075] A measuring member connected to the first adjusting member;

[0076] The ruler 601 is disposed on the upper mold 203, and the interval between two rulers 601 is 2 millimeters;

[0077] Specifically, the measuring component is a pointer 6 , and the pointer 6 is installed on one side of the support frame 4 , and the pointer 6 points to one of the scale marks 601 .

[0078] When moving the support frame 4 , the staff can adjust the moving position length of the pressing block 302 and the lower module 304 by the position of the ruler 601 pointed by the pointer 6 , thereby further facilitating the staff to make adjustments and improving the accuracy of the adjustments.

[0079] Working principle: The staff adjusts the positions of the pressing block 302 and the lower module 304 according to the metal stamping parts to be stamped. The staff twists the two extrusion bolts 506 to move the two extrusion bolts 506 away from the support frame 4. The staff pulls the support frame 4 so that the support frame 4 can drive the two moving blocks 301 to move along the outside of the upper long rod 3. The two moving blocks 301 drive the pressing block 302 to move together. At the same time, the support frame 4 drives the lower module 304 to move along the outside of the lower long rod 303 through the short plate 401 and the bracket 402, so that the lower module 304 moves synchronously with the pressing block 302. The pressing block 302 moves synchronously with the pressing block 302 through the round shell 5, the second spring 501 and the movable block 5 02 drives the protrusion 503 to move together. The protrusion 503 moves out of the groove on the current concave plate 504 under the drive of external force. At this time, the protrusion 503 drives the movable block 502 to move downward along the inner side of the circular shell 5 under the squeeze of the concave plate 504. When the protrusion 503 moves to the groove position of another concave plate 504, the second spring 501 uses its own elastic force to drive the protrusion 503 to move into the inner side of the groove through the movable block 502, so that the protrusion 503 and the groove are fitted together. The staff moves the pressing block 302 and the lower module 304 to the specified position through the position of the ruler 601 pointed by the pointer 6, and then twists the two squeezing bolts 506 in the opposite direction to make the squeezing bolts 506 abut against the support frame 4, through the protrusion 503 is engaged with the groove to fix the position of the pressure block 302, and the support frame 4 is fixed in position by pressing the bolt 506 against the support frame 4. The staff controls the conveying device through the control device to convey the metal sheet to the bottom of a circular cutter 205 and an arc cutter 206, and controls the telescopic end of the telescopic cylinder 102 to shrink, so that the telescopic cylinder 102 drives the top seat 2 to move downward, and the top seat 2 drives the circular cutter 205 and the arc cutter 206 to move downward through the cushion block 201, the first spring 202 and the upper mold 203, and cooperates with the circular cut hole and the arc cut hole of the lower mold 101 to punch and cut the metal sheet. The telescopic end of the telescopic cylinder 102 extends to make the top seat 2 rise, and the first spring 202 uses its own The elastic force supports the upper mold 203 to separate from the cushion block 201, and the upper mold 203 drives the circular cutter 205 and the arc cutter 206 to separate from the lower mold 101, and then controls the conveying device to convey the metal sheet to between the pressing block 302 and the lower module 304, and then controls the telescopic end of the telescopic cylinder 102 to shrink, so that the pressing block 302 punches the metal sheet into the lower module 304 to form the metal sheet. At the same time, another set of circular cutters 205 and arc cutters 206 punch and cut the metal sheet, thereby completing the production of metal stamping parts. The staff controls the unloading device through the control device to unload the metal stamping parts. At the same time, the waste material on the lower mold 101 is cleaned up to continue the subsequent production of metal stamping parts.

[0080] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
