Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a tap production mold. Background Technology

[0002] A tap is a tool, usually referring to a tool used to process internal threads, also known as a threaded tap. It is a cylindrical tool with threads used to cut internal threads in a hole. Currently, some sheet metal parts are manufactured by bending and stamping with continuous sheet metal stamping dies. Several sets of stamping dies are connected to form a processing production line. The sheet metal parts pass through each set of dies in sequence, and each die processes one step. For example, if the sheet metal part entering the die is a thin plate, it is first bent on the left and right sides, then bent on the front and back sides, then holes are drilled and tapped in the holes to produce a tap, and finally the whole piece is chamfered to form the finished product.

[0003] When tapping holes in sheet metal parts, the resulting debris will remain in the slots, making it difficult to remove them promptly after each tapping operation. To remove the debris, the turntable must be removed and inverted so that the debris in each slot can be dislodged by gravity. This method is not only time-consuming and labor-intensive, but also inconvenient and affects the efficiency of subsequent tapping operations on sheet metal parts. Utility Model Content

[0004] To address the technical problems mentioned in the background section, this utility model provides a tap production mold.

[0005] This utility model is achieved using the following technical solution: a tap production mold, including a workbench, a turntable on the top of the workbench, a tapping machine on the top of the workbench located on one side of the turntable, and a material guide groove on the top of the workbench located on the other side of the turntable.

[0006] The top of the turntable has at least one slot along its circumference for inserting sheet metal parts, and the bottom of the turntable has a discharge groove that connects to the bottom of the slot. A protrusion is provided on the top of the worktable located on the side of the guide groove near the rotation center of the turntable. A transmission rod that contacts and engages with the protrusion is axially and elastically inserted into the bottom of the turntable.

[0007] The discharge chute is equipped with a baffle, and the turntable has an internal actuating mechanism.

[0008] When the discharge chute moves directly above the guide chute, the protrusion presses against the bottom of the transmission rod, causing the transmission rod to move axially upward. The actuating mechanism is driven by the axial upward movement of the transmission rod, which can guide the baffle to disengage from the discharge chute.

[0009] As a further improvement to the above solution, a support shaft is fixed to the top of the worktable, and the top of the support shaft is rotatably inserted into the center of the bottom of the turntable.

[0010] As a further improvement to the above solution, the actuating mechanism includes a first cylinder axially disposed inside the turntable, the first cylinder being sleeved on the outside of the transmission rod, the inner wall of the first cylinder having an axially formed spiral track groove, the outer wall of the transmission rod having a track block that slidably engages with the track groove, a first conical tooth being sleeved and fixed on the outer side of the first cylinder, and a second cylinder being radially disposed inside the turntable; one end of the second cylinder having a second conical tooth that engages with the first conical tooth, and the other end having a connecting rod threadedly inserted therein, one end of the connecting rod being connected to the baffle, and a limiting groove having a connecting discharge groove and slidably engaging with the baffle inside the turntable.

[0011] As a further improvement to the above solution, the bottom of the transmission rod is provided with a slider that slides and presses against the protrusion, and the protrusion has inclined surfaces at both ends in the direction of movement of the transmission rod.

[0012] As a further improvement to the above solution, a first spring is sleeved on the outer side of the transmission rod, and the two ends of the first spring are respectively connected to the top wall of the slider and the bottom wall of the turntable.

[0013] As a further improvement to the above solution, a first vertical plate and a second vertical plate are fixed to the top of the turntable. A movable arm that can move radially on the turntable is elastically inserted into the first vertical plate. An oblique hole is opened at the centripetal end of the movable arm. The top of the transmission rod extends to the top of the turntable and is concentrically fixed with a top rod that presses against the oblique hole. A first clamping plate is provided at the centrifugal end of the movable arm. A second vertical plate is provided on the top of the turntable. A second clamping plate is provided on one side of the second vertical plate. A clamping space for clamping and fixing sheet metal parts is formed between the first clamping plate and the second clamping plate.

[0014] When the transmission rod moves upward axially, the top of the push rod presses against the inclined hole, forcing the moving arm to drive the second clamping plate to move away from the first clamping plate.

[0015] As a further improvement to the above solution, a ring body is fixedly sleeved on the outside of the movable arm, and a second spring is sleeved on the outside of the movable arm. The two ends of the second spring are respectively connected to the ring wall of the ring body and the wall of the first upright plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The tap production mold of this utility model, by setting up a turntable, tapping machine, guide groove, discharge groove, protrusion, baffle, etc., can automatically release the sealing effect of the baffle on the discharge groove by simply rotating the turntable to move the discharge groove directly above the guide groove after tapping the sheet metal parts. This allows the debris generated after tapping to fall into the guide groove 27 for easy cleaning and collection, which is convenient and efficient, and ensures the efficiency of subsequent tapping operations on sheet metal parts.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1 to 6 The tap production mold includes a workbench 1, a turntable 2 on top of the workbench 1, a tapping machine 4 on top of the workbench 1 located on one side of the turntable 2, and a material guide groove 27 on top of the workbench 1 located on the other side of the turntable 2.

[0028] The top of the turntable 2 has at least one slot 3 for inserting terminals along the circumferential direction. The bottom of the turntable 2 has a discharge groove 17 that connects to the bottom of the slot 3. The top of the workbench 1 located on the side of the guide groove 27 near the rotation center of the turntable 2 is provided with a protrusion 8. The bottom of the turntable 2 is axially elastically fitted with a transmission rod 6 that contacts and engages with the protrusion 8.

[0029] The discharge chute 17 is equipped with a baffle 16, and the turntable 2 has an actuating mechanism inside.

[0030] When the discharge trough 17 moves directly above the guide trough 27, the protrusion 8 presses against the bottom of the transmission rod 6, causing the transmission rod 6 to move upward axially. The action mechanism is driven by the upward axial movement of the transmission rod 6, which can guide the baffle 16 to disengage from the discharge trough 17, so that the debris generated after tapping can enter the guide trough 27 from the discharge trough 17 and be collected.

[0031] A support shaft 5 is fixed to the top of the workbench 1, and the top of the support shaft 5 is rotatably inserted into the center of the bottom of the turntable 2.

[0032] The actuating mechanism includes a first cylinder 9 axially disposed inside the turntable 2, which is sleeved on the outside of the transmission rod 6. A spiral-shaped track groove 10 is axially formed on the inner wall of the first cylinder 9. A track block 11, which slidably engages with the track groove 10, is provided on the outer wall of the transmission rod 6. A first conical tooth 12 is sleeved and fixed on the outer side of the first cylinder 9. A second cylinder 13 is radially disposed inside the turntable 2. One end of the second cylinder 13 has a second conical tooth 14 that engages with the first conical tooth 12, and the other end is threaded with a connecting rod 15. One end of the connecting rod 15 is connected to a baffle 16. A limiting groove, which connects to the discharge groove 17 and slidably engages with the baffle 16, is formed inside the turntable 2.

[0033] The bottom of the transmission rod 6 is provided with a slider 7 that slides and presses against the protrusion 8. The protrusion 8 has inclined surfaces at both ends in the direction of movement of the transmission rod 6.

[0034] A first spring is sleeved on the outer side of the transmission rod 6, with its two ends connected to the top wall of the slider 7 and the bottom wall of the turntable 2, respectively. When the slider 7 is not pressing the protrusion 8, the first spring is in a non-deformed state; when the slider 7 presses against the protrusion 8, the first spring is compressed and deformed.

[0035] The top of the turntable 2 is fixed with a first vertical plate 18 and a second vertical plate 24 respectively. The first vertical plate 18 is elastically inserted with a movable arm 19 that can move radially on the turntable 2. The movable arm 19 has an oblique hole 20 at its centripetal end. The top of the transmission rod 6 extends to the top of the turntable 2 and is concentrically fixed with a top rod 25 that contacts and engages with the oblique hole 20. The centrifugal end of the movable arm 19 is provided with a first clamping plate 22. The top of the turntable 2 is provided with a second vertical plate 24. A second clamping plate 23 is provided on one side of the second vertical plate 24. A clamping space for terminal clamping and fixing is formed between the first clamping plate 22 and the second clamping plate 23.

[0036] When the transmission rod 6 moves upward axially, the top of the push rod 25 presses against the inclined hole 20, forcing the moving arm 19 to drive the second clamping plate 23 to move away from the first clamping plate 22.

[0037] A ring 21 is fixedly fitted to the outer side of the movable arm 19, and a second spring is fitted on the outer side of the movable arm 19. The two ends of the second spring are respectively connected to the ring wall of the ring 21 and the plate wall of the first vertical plate 18. When the top rod 25 touches the inclined hole 20, the second spring undergoes tensile deformation.

[0038] A pull rod 26 is provided at the top of the movable arm 19.

[0039] The working principle of this embodiment:

[0040] During tapping, the moving arm 19 is pulled centripetally by the pull rod 26 (the second spring is stretched and deformed) to move the first clamping plate 22 away from the second clamping plate 23. Then, the terminal is inserted into the slot 3, and the pull rod 26 is released. The second spring force is released, pushing the first clamping plate 22 towards the second clamping plate 23 to clamp and fix the terminal. The rotating turntable 2 moves the terminal below the tap of the tapping machine 4 for tapping, thus machining the tap in the hole of the terminal.

[0041] The turntable 2 continues to rotate, moving the discharge groove 17 above the guide groove 27. This causes the slider 7 to be pressed by the protrusion 8, which drives the transmission rod 6 to move axially upward. This causes the track block 11 to rub and squeeze the spiral-shaped track groove 10 wall, forcing the first cylinder 9 to rotate unidirectionally. The first cylinder 9 drives the first bevel tooth 12, the second bevel tooth 14, and the second cylinder 13 to rotate, causing the second cylinder 13 and the connecting rod 15 to interact with each other through a threaded action. Under the limiting action of the limiting groove, the baffle 16 is disengaged from the discharge groove 17, allowing the debris generated after tapping to enter the guide groove 27 for collection. In addition, the axial upward movement of the transmission rod 6 can also press the inclined hole 20 through the top rod 25, forcing the moving arm 19 to move centripetally (the second spring is stretched and deformed), so that the first clamping plate 22 moves away from the second clamping plate 23, releasing the clamping state of the terminal, so that the tapped end can be removed.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
