[0023] Please refer to Figures 1 to 7 As shown, the action swing block 5 is squeezed by the upper mold block 1 to drive the action float block 6 to move downward, and then push the action slider 7 to move in the lateral direction to squeeze the actuator 8 upward to stamp the pre-set material strip 200.

[0024] The control pendulum block 4 has a first surface 401 and a second surface 402 disposed on both sides of the first direction, a third surface 403 disposed on both sides of the second direction, and a butt-joint top portion 41. The first direction is perpendicular to the second direction, the first surface 401 and the second surface 402 are arranged in parallel, and the third surface 403 is perpendicular to the first surface 401. The butt-joint top portion 41 is protruding outward and adjacent to the second surface 402, and the butt-joint top portion 41 and the first surface 401 are connected to each other by an arc-shaped connecting surface 404 that arches outward. In addition, the control pendulum block 4 also has a receiving hole 42 that penetrates it in the front-to-back direction.

[0025] The lower mold assembly also has a pressure float block 9 sandwiched between the actuator 8 and the action float block 6, the actuator 8 abuts against one side of the pressure float block 9 in the lateral direction, the action float block 6 abuts against the other side of the pressure float block 9 in the lateral direction, and the control pendulum block 4 can be rotatably accommodated in the pressure float block 9.

[0026] The material pressing float block 9 has a receiving cavity 91 which is open and arranged toward the action float block 6 , and the control pendulum block 4 is rotatably received in the receiving cavity 91 .

[0027] For further information, see Figures 3 to 7 As shown, the pressing float 9 also has an upwardly open insertion hole 92 for the detection module 2 to extend into, and the insertion hole 92 is connected to the receiving cavity 91 so that the detection module 2 entering the insertion hole 92 can press the control pendulum block 4 in the receiving cavity 91.

[0028] In addition, the material pressing float 9 also has a mounting hole 93 that penetrates the material pressing float along the front-rear direction, the mounting hole 93 is connected to the receiving cavity 91, and its extending direction is perpendicular to the transverse direction. The mounting hole 93 is aligned with the receiving hole 42 of the control pendulum block 4, so that an axle pin 103 is inserted and the control pendulum block 4 is rotatably mounted in the material pressing float 9.

[0029] Please refer to Figure 1 and Figures 5 to 7 As shown, the upper mold assembly also has a limiter 3 that moves synchronously with the upper mold block 1, and the limiter 3 and the upper mold block 1 are disposed on both sides of the detection module 2 in the lateral direction to crimp and position the pre-set material strip.

[0030] Please refer to Figures 1 to 7 As shown, the actuating member 8 is provided with an actuating portion 81 located at the top thereof and protruding upward. The actuating portion 81 is located at one end of the actuating member 8 close to the material pressing float 9 and is arranged opposite to the yielding recess arranged at the bottom of the limiting member 3.

[0031] The actuating member 8 also has a coupling protrusion 82 at its bottom for cooperating with the actuating slider 7 . The coupling protrusion 82 is provided with a first inclined surface 821 on a side thereof close to the material pressing float 9 . The actuating slider 7 has a recessed portion 71 for intermittently accommodating the coupling protrusion 82 .

[0032] The action slider 7 has a second inclined surface 712 that forms the recessed portion 71. In the initial state, that is, when the preset hole on the preset material belt 200 is not in the corresponding position with the detection module 2, the combining protrusion 82 is completely accommodated in the recessed portion 71, and the first inclined surface 821 is in contact with the second inclined surface 712.

[0033] The action float 6 has a first guide surface 61 which is located at the bottom and extends obliquely, and the action slider 7 has a second guide surface 72 which abuts against the first guide surface 61 .

[0034] The action float block 6 also has a containing space 62 for accommodating the action pendulum block 5 , and the containing space 62 is open upward so that the action pendulum block 5 is open toward the material pressing float block 9 for the control pendulum block 4 to extend into after rotation.

[0035] Specifically, the accommodating space 62 is L-shaped as a whole, and includes a first accommodating channel 621 and a second accommodating channel 622 that are connected. The first accommodating channel 621 is open upward and connected to the second accommodating channel 622 downward. The second accommodating channel 622 penetrates the action float 6 in the lateral direction.

[0036] In addition, the action float 6 also has a through hole 63 penetrating the action float 6 in the front-rear direction, and the through hole 63 is connected to the accommodating space 62 .

[0037] In the present invention, the control pendulum block 4 and the material pressing float block 9 move synchronously in the up and down directions, and the control pendulum block 4 rotates in the receiving cavity 91 of the material pressing float block 9 to press against the abutting surface 521 of the action pendulum block 5 and drive the action pendulum block 5 to rotate.

[0038] The action swing block 5 and the action float block 6 move synchronously in the up-down direction. The action swing block 5 has a pivoting portion 51 and a swing arm 52 extending from the pivoting portion 51. The abutting surface 521 is formed on the side of the swing arm 52 close to the material pressing float block 9. The pivoting portion 51 is rotatably received in the second accommodating channel 622, and the swing arm 52 is received in the first accommodating channel 621. The pivoting portion 51 is provided with a pivot hole 512 penetrating the pivoting portion 51 in the front-to-back direction. The pivot hole 512 is aligned with the through hole 63 provided on the action float block 6, so that another shaft pin 103 can be inserted into the pivot hole 512 and the through hole 63.

[0039] When the detection module 2 does not detect the preset holes on the preset material belt, the abutment surface 521 is in a vertical state perpendicular to the horizontal plane; when the detection module 2 detects the preset holes on the preset material belt, the action pendulum block 5 rotates to make the abutment surface 521 in an inclined state with an angle that is not a right angle to the horizontal plane, and at this time, the top surface 523 of the action pendulum block 5 is parallel to the horizontal plane.

[0040] The detection module 2 has a detection pin 21 and an elastic member 22 connected to the detection pin 21 . The detection pin 21 passes through a preset hole of the preset material strip and then presses against the control pendulum block 4 .

[0041] The die device with intermittent action mechanism also has a push rod 101 supported at the bottom of the material pressing float 9 and a spring 102 elastically connected to the push rod 101. In the present invention, the swing arm 52 is also connected to a spring 102 on the side opposite to the abutment surface 521. The action slider 7 also protrudes a spring 102 on the side opposite to the second guide surface 702. The spring 102 is partially accommodated in the action slider 7, and the other part protrudes out of the action slider 7.

[0042] The action slider 7 has a sliding channel 73 formed through it in the height direction, and the sliding channel 73 extends a certain length in the transverse direction so that the action slider 7 can still accommodate the push rod 101 when moving in the transverse direction. Further, both ends of the sliding channel 73 in the transverse direction are arc-shaped to adapt to the outer surface of the push rod 101.

[0043] In the present invention, because different types of material strips to be punched (i.e., the pre-set material strips 200) all have regularly arranged preset holes, the present invention uses the detection pins 21 to detect the positions of the preset holes, thereby realizing the punching action of the corresponding parts. When the preset holes on the pre-set material strip 200 are not in the corresponding positions with the detection pins 21, the upper mold assembly moves downward, and the detection pins 21 are interfered by the pre-set material strip 200. Under the action of the pressing float 9, the detection pins 21 are lifted up and move upward, and the entire device does not perform a punching action. At this time, the first surface 401 of the control pendulum block 4 is set at an angle to the horizontal plane, and its arc-shaped connecting surface 404 is against the abutment surface 521 of the action pendulum block 5.

[0044] When the preset hole on the preset material strip 200 and the detection pin 21 are in the same position, the upper mold assembly moves downward, and the detection pin 21 passes through the preset hole on the preset material strip 200, touches the control pendulum block 4 of the lower mold assembly and causes it to rotate, so that the first surface 401 and the second surface 402 of the control pendulum block 4 are parallel to the horizontal plane; the rotation of the control pendulum block 4 causes the action pendulum block 5 to rotate accordingly, and the upper mold assembly continues to move downward so that the upper mold pressure block 1 supports the action pendulum block 5, thereby driving the action float block 6 downward, and further causing the action slider 7 in contact with the action float block 6 to slide laterally, and the lateral sliding of the action slider 7 drives the actuating member 8 to move, and the first inclined surface 821 of the combined protrusion 82 moves upward along the second inclined surface 712 until the combined protrusion 82 completely slides out of the recessed portion 71 and is carried on the upper surface of the action slider 7, and the actuating member 8 moves upward to act on the preset material strip 200 to achieve the required stamping action. After the punching action is completed, the upper and lower die assemblies are separated, and each component is reset under the restoring force of the corresponding spring 102 to return to the initial position.

[0045] Since the preset holes on the preset material strip 200 are regularly spaced, the die device of the present invention can adaptively and intermittently perform stamping actions on the preset material strip 200 without the need for external force control or external control mechanism. The device structure is simple and stable, and the components are easy to arrange. There is no need to replace parts when producing different material numbers, which greatly reduces human errors.

[0046] By means of the punching die device with an intermittent action mechanism of the present invention, it is possible to produce products of the same type but with spacing structures of different spacings in a set of stamping dies; at the same time, multiple sets of such intermittent action mechanisms can be arranged in the punching die device, and multiple actions can be performed at the same position on the product, thereby realizing the stamping of complex spacing structures, which is impossible for ordinary externally controlled intermittent action mechanisms.

[0047] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
