DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0025] Embodiment 1:

[0026] See also Figure 1-5 The continuous stamping die assembly in this embodiment includes a workbench 1 and a die base 4. A transmission channel 5 is provided on the workbench 1 along its central axis. The die base 4 is fixed at a position located on the central axis in the transmission channel 5. A mounting hole is provided at a position located on the central axis in the transmission channel 5, and the width of the mounting hole is equal to the width of the transmission channel 5. A loading box 2 is detachably fixed in the mounting hole. The loading box 2 is a rectangular parallelepiped with a hollow interior and a missing top surface. A loading port 12 is provided on the side of the loading box 2. A loading plate 13 is slidably inserted into the inner side wall of the loading box 2. A cylinder 14 is fixed between the bottom surface of the loading plate 13 and the inner bottom wall of the loading box 2. The upper end surface of the loading box 2 and the top surface of the die base 4 are located on the same axis.

[0027] A through opening 6 is symmetrically provided on the workbench 1 along the central axis of the transmission channel 5, and a reciprocating screw 23 is rotatably connected to the through opening 6 along its length direction through a bearing. A motor 10 is fixed to the back of the workbench 1, and the output shaft of the motor 10 is connected to the end of the screw, and a clamping assembly is provided on the screw.

[0028] When in use, the workpiece is placed on the loading plate 13 of the loading box 2 from the loading port 12. At this time, the cylinder 14 is in operation, and the workpiece is driven to move upward through the loading plate 13. After the workpiece is removed from the loading box 2, the motor 10 is in operation to drive the screw to rotate. After the screw rotates, it drives the slide rail 11 to move in the through port 6. After the slide rail 11 moves toward the die base 4, the clamping assembly on the slide rail 11 can clamp the workpiece removed from the loading box 2. At the same time, the workpiece is held in the clamping assembly. With the cooperation, it will also move synchronously to allow the workpiece to be continuously stamped. After the slide rail 11 moves to the vicinity of the module, the clamping assembly can release the workpiece, and the workpiece completes the continuous stamping. At this time, the slide rail 11 is reset under the action of the screw rod, and the workpiece in the loading box 2 is moved out again by the loading plate 13. The reset slide rail 11 moves again, and the workpiece moved out again is driven to the mold for stamping. Repeating the above steps can realize automatic loading of the workpiece to be stamped, thereby improving the stamping work efficiency.

[0029] Embodiment 2:

[0030] The basic content is the same as that of Example 1, except that:

[0031] See also Figure 3 In this embodiment, a support block 7 is fixed on the position on the central axis of the transmission channel 5, and the support block 7 is located between the mold base 4 and the loading box 2. The upper end surface of the loading box 2, the top surface of the support block 7 and the top surface of the mold base 4 are located on the same axis.

[0032] When in use, after the clamping assembly moves the workpiece out of the loading box 2, the workpiece will first move on the support block 7, supported by the support block 7, and then move from the support block 7 to the mold. Supporting the workpiece by the support block 7 can make the workpiece more stable during transmission.

[0033] Embodiment 3:

[0034] The basic content is the same as that of Example 1, except that:

[0035] See also Figure 3-5 , the clamping assembly in this embodiment includes a slide rail 11, a slider 17, a spring 15, a connecting column 3, a limit plate 8 and an abutment block 19;

[0036] The slide rail 11 is threadedly connected to the screw rod, and the side of the slide rail 11 abuts against the side wall of the through opening 6. The slider 17 is slidably connected in the slide rail 11. A spring 15 is fixed between the side wall of the slide rail 11 close to the loading and the side of the slider 17 close to the loading box 2. The connecting column 3 is fixed to the top surface of the slider 17. A groove 22 is provided on the outer side of the connecting column 3 along the sliding direction of the slider 17. The abutment block 19 is detachably fixed in the groove 22. The limit plate 8 is fixed on the workbench 1 at a position close to its side corresponding to the connecting column 3. The two corners of the limit plate 8 close to the loading box 2 are set as arc corners 9, and the two arc corners 9 are respectively located at the loading box 2 and the mold.

[0037] When in use, after the slide rail 11 moves, the connecting column 3 on the slider 17 will contact the arc corner 9 on the limit plate 8. With the continuous movement of the slider 17, the connecting column 3 can be squeezed through the arc corner 9, and the slider 17 will also move toward the upper material box 2 under the action of the connecting block, and when the slider 17 moves, it will also squeeze the spring 15. When the connecting column 3 moves from the arc corner 9 to the side of the limit plate 8 and moves on the side of the limit plate 8, the abutment block 19 can clamp the workpiece moved out of the loading box 2. When the slide rail 11 moves to make the connecting column 3 move to another arc corner 9, the connecting column 3 loses its extrusion, and the squeezed spring 15 and the moved abutment block 19 also rebound and reset, and release the workpiece. After the slider 17 is reset, the workpiece can be clamped again.

[0038] Embodiment 4:

A plurality of insertion holes 18 are provided on the abutment block 19 at equal intervals corresponding to the pin 16, and the pin 16 is slidably inserted in the insertion holes 18.

[0041] During application, when clamping workpieces of different sizes, the position of the abutment block 19 can be adjusted by plugging the latch 16 into different insertion holes 18, so that the abutment block 19 can abut against the workpiece.

[0042] In another specific embodiment:

[0043] The latch pin 16 is fixed vertically on the side wall of the groove 22 along the transverse direction.

[0044] Embodiment 5:

[0045] The basic content is the same as that of Example 3, except that:

[0046] See also Figure 4-5In this embodiment, the positioning portion 20 of the abutment block 19 is slidably connected in the groove 22, the socket 18 is opened on the positioning portion 20 of the abutment block 19, the abutment portion 21 of the abutment block 19 faces the direction of the loading box 2, the vertical projection of the abutment block 19 is L-shaped, and the abutment portion 21 is located below the side of the positioning portion 20 close to the loading box 2.

[0047] During use, during the process of adjusting the abutting block 19 , the abutting block 19 is connected to the connecting column 3 via the positioning portion 20 . Meanwhile, after the connecting column 3 moves, the abutting block 19 can abut against the workpiece via the abutting portion 21 .
