Fig. 1 is a perspective view and fig. 2 is a partial cross-sectional view of an embodiment of the present utility model, and referring to fig. 1 and 2, an embodiment of the present utility model provides a wire continuous processing die, which comprises a base 100, wherein a fixing main plate 200, an upper punch 300 and a lower die core 400 are disposed on the base 100. The upper punch 300 is located at the front side of the stationary main plate 200. The upper punch 300 is movable up and down in the vertical direction. The fixing main plate 200 has a through hole so that the lower mold core 400 can move through the fixing main plate 200, and the lower mold core 400 can move in translation along the front and rear side direction.

Further, side dies 500 are provided at both left and right sides of the housing 100, wherein the side die 500 of one side has a wire guide tube 510, and the upper punch 300 has a cutting edge to cut the wire 900. For example, referring to fig. 4, defining the right side of fig. 4 as the input side, the wire 900 passes through the right side die 500, the left side die 500 is used to limit the wire 900, and the cutting edge of the upper punch 300 is correspondingly opposite to the right side of the upper punch 300.

Still further, an upper mold bending cavity 310 and a lower mold bending cavity 410 are provided between the upper punch 300 and the lower mold core 400. The upper and

310 and 410 cooperate to complete the forming operation of bending the cut wire 900 into a workpiece.

In the standby state, the upper punch 300 is in a raised state and the lower die core 400 is in a retracted state.

In actual operation (right side is input side), the wire 900 passes from the right side die 500 until it abuts the left side die 500. Then the upper punch 300 is pressed downward, and the lower die core 400 is correspondingly extended forward to the fixing main plate 200, the cutting edge of the upper punch 300 cuts off the portion of the wire 900 extending out of the right side die 500, and simultaneously the upper die bending cavity 310 of the upper punch 300 and the lower die bending cavity 410 of the lower die core 400 cooperate to press the cut wire 900 into a workpiece. Finally, the upper punch 300 is re-lifted, the lower die core 400 is retracted again, and the workpiece is blocked by the fixed main plate 200 (corresponding to the completion of the demoulding operation) and falls down to be collected, thus completing the cutting and forming operation.

It is conceivable that if the left side is the input side, the wire 900 passes through the left side die 500, and the right side die 500 restrains the wire 900.

In some embodiments, the upper punch is controlled to move up and down by a lifting device 600, the lifting device 600 includes a lifting plate 610, and the upper punch 300 is connected to the lifting plate 610.

So that when the lifter plate 610 descends, the upper punch 300 follows the descent simultaneously with the guide drive insert 700. The insert guide inclined surface 710 of the guide driving insert 700 is matched with the lower die guide inclined surface 420 of the lower die core 400, so that the lower die core 400 can be driven to advance, and the lower die core 400 does not need to be additionally provided with a control device for controlling the forward and backward movement.

It is contemplated that the dimensions of the guide drive insert 700 and lower mold core 400 will depend on the actual needs.

In this embodiment, the insert guide inclined surface 710 and the lower die guide inclined surface 420 may be inclined to the upper side of the front side.

In some embodiments, referring to fig. 5, a board guide seat 800 is provided on the fixed main board 200, and a guide groove is provided on the board guide seat 800 for guiding and driving the board 700 to move.

In this embodiment, optionally, the demolding spring 810 is mounted on the insert plate guide seat 800, so that the whole structure is more compact.

In some embodiments, referring to fig. 3, bending limiting grooves 311 are formed on the left and right sides of the upper bending cavity 310, and are used to clamp the left and right ends of the cut portion of the wire 900, so as to ensure the effect of the bending process.

In some embodiments, the lower mold core 400 is provided with a guide 430 for guiding the demolded workpiece slide to a designated position.

In this embodiment, the material guiding member 430 is optionally a diagonal bar on the left and right sides.

In some embodiments, the side mold 500 has a guide slot for guiding the movement of the upper punch 300, so as to ensure that the lifting movement of the upper punch 300 does not deviate.
