[0036] In this embodiment, a transmission device (not shown) for transmitting the metal plate is also provided beside the progressive die stamping equipment. When the equipment is in use, the transmission device and the hydraulic cylinder are started. The transmission device will continuously and slowly move the metal plate onto the lower die 3. The two rows of limit blocks on the lower die 3 can limit the metal plate. After the hydraulic cylinder is started, it will drive the upper fixing seat 1 and the upper die 2 to press down onto the lower die 3 on which the metal plate is placed. Combining Figures 2-4 , the specific steps of continuous stamping of the metal plate are as follows:

[0037] Step 1: The first stamping head 16 first punches holes in the metal plate. When punching holes, the transmission device stops transmitting the metal plate. At the same time, after the first stamping head 16 enters the first punching groove 5, the first hole position on the first 239 fixing block in the metal plate is punched;

[0038] Step 2: The hydraulic cylinder drives the upper die 2 to move upward. The transmission device will continue to move the metal plate forward. Then the hydraulic cylinder drives the upper die 2 to move downward. At the same time, the transmission device stops transmitting the metal plate, skips the first 239 fixing block, and punches the first hole position on the second 239 fixing block in the metal plate;

[0039] Step 3: The hydraulic cylinder drives the upper die 2 to move upward. The transmission device will continue to move the metal plate forward. Then the hydraulic cylinder drives the upper die 2 to move downward. At the same time, the transmission device stops transmitting the metal plate. Subsequently, the draw bead 6 will squeeze the first 239 fixing block and enter the first groove 17 to perform a drawing and wrapping process on the first 239 fixing block. Similarly, skip the second 239 fixing block and punch the third 239 fixing block;

[0040] Step 4: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves to the first convex block 7, and the equipment skips this 239 fixing block, performs a drawing and wrapping process on the second 239 fixing block, skips the third 239 fixing block, and punches the fourth 239 fixing block;

[0041] Step 5: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves to the second convex block 7. A row of second stamping heads 19 press down on the first 239 fixing block and enter the corresponding row of second punching grooves 8 to complete the second punching of the first 239 fixing block. The remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0042] Step 6: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves to the third convex block 7. The first trimming tool 20 at the bottom of the upper die 2 trims the upper edge of the first 239 fixing block. After the first trimming tool 20 enters the first tool groove 9, the first trimming operation of the first 239 fixing block is completed. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0043] Step 7: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves onto the fourth bump 7. The second trimming tool 21 at the bottom of the upper die 2 trims the right side edge of the first 239 fixing block. After the second trimming tool 21 enters the second tool slot 10, the second trimming operation of the first 239 fixing block is completed. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0044] Step 8: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves onto the fifth bump 7. The equipment skips this step for this 239 fixing block. Meanwhile, the second trimming tool 21 trims its left side edge. After the second trimming tool 21 enters the second tool slot 10, the third trimming operation of the first 239 fixing block is completed. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0045] Step 9: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves onto the sixth bump 7. Both of the two third punching heads 22 punch holes in the first 239 fixing block. Subsequently, the two third punching heads 22 will respectively enter the two third punching slots 11 to complete the third punching. At the same time, the first bending part 23 cooperates with the first bending slot 12 to bend the right side edge of this 239 fixing block by 45 degrees. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0046] Step 10: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves onto the seventh bump 7. The second bending part 26 cooperates with the second bending slot 13 to bend the right side edge of the first 239 fixing block by 90 degrees. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0047] Step 11: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves onto the eighth bump 7. The third trimming tool 24 trims the lower edge of this 239 fixing block. After the third trimming tool 24 enters the third tool slot 14, the fourth trimming is completed. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here;

[0048] The twelfth step: Under the action of the hydraulic cylinder and the transmission device, the first 239 fixing block moves to the ninth bump 7. The third bending piece 29 cooperates with the third bending groove 30 to bend the lower edge of the first 239 fixing block. At the same time, the fourth trimming cutter 25 trims the lower edge of the bent first 239 fixing block. Under the action of the transmission device, the second 239 fixing block pushes the first 239 fixing block out of the material. Similarly, the remaining 239 fixing blocks on the metal plate are processed synchronously and continuously according to the above operations, which will not be elaborated here.

[0049] After the above twelve steps, and with the continuous operation of the equipment, the metal plate can be continuously processed into several 239 fixing blocks; in the original single-process stamping production, 3 punching presses and 1 shearing machine were required, and 5 employees were needed, with a production capacity of 400 pieces / h; now it is changed to continuous die processing, only 1 large-tonnage punching press is required and 1 person operates it, and the production capacity can be increased to 1000 pieces / h; the transmission device uses a small feeder, and the material is fed through a strip. The die steps are concentrated in a set of continuous dies. Although the investment cost is large, it can reduce costs and increase efficiency. When the product is mass-produced, the cost can be recovered in a short period; continuous processing can ensure product accuracy and consistency.
