Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a riveting punch structure for a stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts. The punch is an important component of stamping dies, used to stamp products.

[0003] Existing stamping dies cannot replace the punch holder with a matching one according to different stamping products. Furthermore, when the die block and the punch are riveted together, uneven force is easily applied, which can cause product deformation. Therefore, there is an urgent need for a riveting punch structure for stamping dies. Utility Model Content

[0004] The purpose of this utility model is to provide a riveting punch structure for stamping dies, so as to solve the problems mentioned in the background art, that the punch of the existing stamping die cannot be replaced with a matching punch seat according to different stamping products, and that the die block and the punch are prone to uneven force when riveted, which causes product deformation, and that the punch is prone to high temperature due to impact and friction during long-term operation, which will affect the service life of the punch if not cooled in time.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a riveting punch structure for a stamping die, including a punch seat, a heat sink is provided on the inner side of the punch seat, a bud-pulling groove is provided on the top of the punch seat, a product is provided on the outer side of the punch seat, a punch body is provided at the bottom end of the heat sink, a stop is provided on the outer side of the product, a locking structure is provided on the outer side of the punch body, a heat dissipation structure is provided inside the punch body, and a riveting block is provided below the stop.

[0006] The engaging structure includes a plug rod, with limit blocks on both sides of the plug rod, and a support block on the outer wall of the plug rod. A threaded ring is provided below the support block, and a slot is provided at the bottom of the punch seat.

[0007] The heat dissipation structure includes a temperature-sensitive color-changing sticker, a water delivery tank is provided inside the punch body, a water inlet pipe is connected to one side of the water delivery tank, and a heat dissipation water tank is provided at the top of the water delivery tank. A connecting sleeve is fitted onto the water inlet pipe, and a water outlet pipe is provided on one side of the punch body.

[0008] Preferably, the punch seat and the heat sink are connected by a threaded connection, the inner side of the punch body is provided with a storage groove that matches the insertion rod, and the inner side of the storage groove is provided with a moving groove that matches the limiting block.

[0009] Preferably, the threaded ring is movably connected to the punch body via a thread, the insert rod is movably connected to the punch body via a limiting block and a moving groove, and the insert rod is engaged with the slot.

[0010] Preferably, the punch holder and the punch body are fixedly connected by a plug rod, a limiting block and a threaded ring, and there are two plug rods and slots.

[0011] Preferably, the product is engaged with the punch seat, and there are two water delivery tanks, with the bottom ends of the two water delivery tanks respectively connected to the inlet pipe and the outlet pipe.

[0012] Preferably, the top of the water supply tank extends into the interior of the heat dissipation tank, and connecting sleeves are fitted onto the outer sides of both the inlet pipe and the outlet pipe.

[0013] Preferably, the thermochromic sticker is fixedly connected to the punch body by adhesive.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model, by setting up a punch holder, a threaded ring, a plug rod, and a slot, allows for the replacement of other punch holders when the threaded ring is screwed on. The threaded ring moves downward on the outside of the punch body. As it moves downward, the plug rod, driven by its own weight, moves downward through the limiting blocks on both sides and the moving groove, and then moves downward inside the receiving groove. At the same time as it moves downward, it is pulled out of the slot at the bottom of the punch holder. After the threaded ring moves down to the designated position, the plug rod is completely pulled out of the punch holder. Then, the punch holder can be screwed on to separate it from the heat sink at the top of the punch body through the threads, thus achieving the disassembly of the punch holder, and then other punch holders can be replaced.

[0016] Secondly, by setting up a budding groove, a stop block, and a punch seat, the product is fixed on the stop block, so that when the stop block moves the product downward, it engages with the outside of the punch seat. Under the restriction of the rivet block, it rivets with the budding groove on the outer wall of the punch seat. Through the guidance of the arc-shaped budding groove, the product is first subjected to lateral force, and then subjected to compressive force after flipping. This changes the order of force application, making the product less prone to deformation and resulting in a better flat surface. At the same time, it avoids uneven force application and local cracking of the product, and indirectly enhances the rivet force.

[0017] Third, this utility model, by setting up a temperature-sensitive color-changing sticker, a water inlet pipe, a water delivery pipe, and a heat dissipation tank, allows the temperature of the punch holder and punch body to be detected during operation. Different colors indicate different temperatures, enabling workers to promptly detect temperature changes. At high temperatures, the water inlet and outlet pipes are connected to external water pipes via connecting sleeves. Then, external coolant is controlled to enter the heat dissipation tank through the water inlet and water delivery pipes. The low-temperature coolant exchanges heat with the heat dissipation base, which in turn exchanges heat with the punch holder. After the heat exchange, the punch holder gradually cools down, while the coolant is discharged through the water outlet pipe, achieving coolant circulation and ensuring that the punch holder and punch body remain at a low temperature at all times.

The outer wall of the punch is provided with a support block 403, and a threaded ring 404 is provided below the support block 403. The bottom of the punch seat 1 is provided with a slot 405. The punch seat 1 and the heat sink 3 are connected by threads. The inner side of the punch body 2 is provided with a storage groove that matches the insertion rod 401, and the inner side of the storage groove is provided with a moving groove that matches the limiting block 402. The threaded ring 404 is connected to the punch body 2 by threads. The insertion rod 401 is connected to the punch body 2 by the limiting block 402 and the moving groove, and the insertion rod 401 is engaged with the slot 405. The base 1 and the punch body 2 are fixedly connected by a rod 401, a limiting block 402, and a threaded ring 404. There are two rods 401 and two slots 405. When replacing the punch base 1, the threaded ring 404 is screwed down, causing it to move downwards on the outside of the punch body 2. During this downward movement, the rod 401, driven by its own weight, moves downwards through the limiting blocks 402 on both sides and the moving groove, and then moves downwards inside the receiving groove. Simultaneously, it is pulled out of the slot 405 at the bottom of the punch base 1. After the threaded ring 404 moves to the designated position, the rod 401 is then pulled out of the punch body 2. The punch holder 1 is completely pulled out, and then the punch holder 1 can be screwed on to separate it from the heat sink 3 at the top of the punch body 2 via threads, thus disassembling the punch holder 1. Then, the punch holder 1 to be replaced is first fixed to the heat sink 3 via threads, and then the threaded ring 404 is screwed on. The threaded ring 404 moves upward on the outside of the punch body 2. When it moves upward, it pushes the insertion rod 401 upward in the storage groove through the support block 403, so that after it moves up completely, it is inserted into the slot 405 at the bottom of the punch holder 1, thus fixing the punch holder 1 to the punch body 2. The punch replacement is then completed.

[0029] Please see Figures 6-8A riveting punch structure for a stamping die, wherein the heat dissipation structure 8 includes a thermochromic sticker 801, a water supply groove 804 is provided inside the punch body 2, a water inlet pipe 802 is connected to one side of the water supply groove 804, and a heat dissipation groove 805 is provided at the top of the water supply groove 804, a connecting sleeve 803 is sleeved on the water inlet pipe 802, a water outlet pipe 806 is provided on one side of the punch body 2, a product 6 is engaged with the punch seat 1, there are two water supply grooves 804, the bottom ends of the two water supply grooves 804 are respectively connected to the water inlet pipe 802 and the water outlet pipe 806, the top of the water supply groove 804 extends into the interior of the heat dissipation groove 805, and a connecting sleeve 803 is sleeved on the outer side of both the water inlet pipe 802 and the water outlet pipe 806, the thermochromic sticker 801 is connected to the punch body 2 via The punch holder 1 and punch body 2 are fixed together with glue. During operation, the temperature-sensitive color-changing sticker 801 detects the temperature changes and uses different colors to indicate different temperatures so that the staff can detect temperature changes in time. When the temperature is high, the water inlet pipe 802 and water outlet pipe 806 are connected to the external water pipe through the connecting sleeve 803. Then, the external coolant is controlled to enter the heat dissipation tank 805 through the water inlet pipe 802 and the water delivery tank 804. The low temperature coolant exchanges heat with the heat dissipation base 3, so that the low temperature heat dissipation base 3 exchanges heat with the punch holder 1. After the heat exchange, the punch holder 1 gradually cools down. At the same time, the coolant is discharged through the water outlet pipe 806 to realize the circulation of coolant, so as to ensure that the punch holder 1 and punch body 2 are always kept at a low temperature.

[0030] When replacing the punch holder 1, screw on the threaded ring 404. The threaded ring 404 moves downward on the outside of the punch body 2. As it moves downward, the insertion rod 401, driven by its own weight, moves downward through the limiting blocks 402 on both sides and the moving groove, and then moves downward inside the receiving groove. At the same time, it is pulled out of the slot 405 at the bottom of the punch holder 1. After the threaded ring 404 moves to the designated position, the insertion rod 401 is completely pulled out of the punch holder 1. Then, the punch holder 1 can be screwed on to separate it from the heat sink 3 at the top of the punch body 2 through the threads, thus achieving... The punch holder 1 is disassembled, and the punch holder 1 to be replaced is first fixed to the heat sink 3 by threads. Then, the threaded ring 404 is screwed on, and the threaded ring 404 moves upward on the outside of the punch body 2. When it moves upward, it pushes the insertion rod 401 upward in the storage groove through the support block 403. After it has moved up completely, it is inserted into the slot 405 at the bottom of the punch holder 1, so that the punch holder 1 and the punch body 2 are fixedly installed. The punch replacement is then completed. The product 6 is fixed on the stop block 7, so that when the stop block 7 moves the product 6 downward, it engages with the outside of the punch holder 1 and is riveted. Under the constraint of block 9, the product 6 is riveted to the budding groove 5 on the outer wall of the punch seat 1. Guided by the arc-shaped budding groove 5, the product 6 is first subjected to lateral force, and then to compressive force after flipping. This changes the order of force application, making the product 6 less prone to deformation and resulting in a better flat surface. It also avoids uneven force application and local cracking of the product 6, indirectly enhancing the riveting force. During the operation of the punch seat 1 and the punch body 2, the thermochromic sticker 801 detects temperature changes and uses different colors to indicate different temperatures, so that staff can detect them in a timely manner. When the temperature changes, at high temperatures, the inlet pipe 802 and outlet pipe 806 are connected to the external water pipe through the connecting sleeve 803. Then, the external coolant is controlled to enter the heat dissipation tank 805 through the inlet pipe 802 and the water delivery tank 804. The low-temperature coolant exchanges heat with the heat sink 3, so that the low-temperature heat sink 3 exchanges heat with the punch seat 1. After the heat exchange, the punch seat 1 gradually cools down. At the same time, the coolant is discharged through the outlet pipe 806 to realize the circulation of coolant, so as to ensure that the punch seat 1 and the punch body 2 are always kept at a low temperature.
