Description

Technical Field

[0001] This utility model relates to the field of alloy resistor production and processing technology, specifically to a high-efficiency alloy resistor stamping die. Background Technology

[0002] In the field of electronic equipment manufacturing, alloy resistors are a crucial type of electronic component. Typically made of alloy materials, their working principle is based on Ohm's law. When current flows through a resistive element, the resistance to the current creates a voltage drop, thus enabling precise control of the current and voltage in the circuit. Due to their excellent electrical properties, alloy resistors are widely used in various electronic products, such as mobile phones, computers, and automotive electronics.

[0003] In the production process of alloy resistors, the stamping die is a crucial link, as its performance directly affects the production efficiency and quality. However, existing stamping dies generally lack a real-time detection mechanism for the position of the alloy resistor within the die. During the stamping process, if the position of the alloy resistor shifts, it will cause various defects in the stamped product. For example, poor electrode connection will prevent the resistor from conducting current properly in the circuit; deformation of the resistor body will change the resistance value, severely affecting product performance. Furthermore, positional shift can also cause accelerated localized wear of the die, shortening its lifespan and thus increasing production costs.

[0004] In order to detect the position of the alloy resistor in the die in real time during the stamping process, prevent the alloy resistor from shifting, ensure product performance, and extend the service life of the die, we propose a high-efficiency alloy resistor stamping die.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Beneficial effects

[0015] This invention provides a high-efficiency alloy resistance stamping die. Compared with the prior art, it has the following advantages:

[0016] This high-efficiency alloy resistor stamping die allows for adjustment of the distance between two sets of limiting rings by rotating the rotating cover. The two sets of limiting rings clamp the alloy resistor on both sides, preventing displacement. If the alloy resistor displaces during stamping, the pressure block, under the action of a spring, presses down on the pressure sensor. Upon receiving the pressure signal, the pressure sensor immediately stops the machine and issues an alarm signal, reminding the operator to reset the alloy resistor. This allows for real-time monitoring of the alloy resistor's position within the die during the stamping process, preventing displacement, ensuring product performance, and extending the die's lifespan.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency alloy resistance stamping die, including an upper die base 1, an upper pad 2 fixedly connected to the bottom of the upper die base 1, a punch 3 installed at the bottom of the upper pad 2, a lower die base 5 provided below the upper die base 1, a lower pad 7 fixedly connected to the top of the lower die base 5, a die cavity 8 fixedly connected to the top of the lower pad 7, a forming cavity 11 opened on the die cavity 8, a forming block 12 fixedly connected to the bottom of the punch 3, two sets of material passage holes 13 connected to the forming cavity 11 opened on the die cavity 8, a detection component for detecting whether the alloy resistance is offset is installed on the lower die base 5, and a conveying component for conveying the alloy resistance is installed on the lower die base 5;

[0024] The testing assembly includes two sets of testing frames 9. The testing frames 9 are fixedly connected to the top of the lower mold base 5. The bottom of the inner cavity of the testing frame 9 is fixedly connected to the mounting base 17. The bottom of the inner cavity of the mounting base 17 is fixedly installed with a pressure sensor 18. The top of the inner cavity of the testing frame 9 is fixedly connected to the mounting cover 14. The inner wall of the mounting cover 14 is slidably installed with a pressure block 15. The top of the pressure block 15 is fixedly connected to a spring 16. The top of the spring 16 is fixedly connected to the top of the inner cavity of the testing frame 9.

[0025] In use, the alloy resistor is conveyed by the conveying component and passed through the material passage hole 13 on the die 8, so that the alloy resistor is located in the forming cavity 11. Then, the upper die base 1 is driven by the cylinder to descend, so that the punch 3 descends and the alloy resistor is stamped by the forming block 12. During normal stamping, the alloy resistor is always located between the pressure block 15 and the mounting base 17. The pressure block 15 is retracted in the mounting cover 14 under the restriction of the alloy resistor. If the alloy resistor is displaced during the stamping process, the pressure block 15 is not restricted and moves downward under the action of the spring 16, squeezing the pressure sensor 18. After receiving the pressure signal, the pressure sensor 18 immediately controls the machine to stop and issues an alarm signal to remind the operator to reset the alloy resistor. This realizes real-time detection of the position of the alloy resistor in the mold during the stamping process, prevents the position of the alloy resistor from being displaced, ensures product performance, and extends the service life of the mold.

[0026] An upper contact roller 20 is rotatably mounted on the pressure block 15, and a lower contact roller 19 is rotatably mounted on the mounting base 17. This prevents the pressure block 15 and the mounting base 17 from directly contacting the surface of the alloy resistor, thus preventing excessive friction from affecting the conveying of the alloy resistor.

[0027] The conveying assembly includes two sets of limit frames 10. The limit frames 10 are fixedly connected to the side of the lower mold base 5. A drive roller 21 and a driven roller 23 are rotatably mounted on the limit frames 10. A motor 22 is fixedly mounted on the limit frames 10. The output end of the motor 22 is fixedly connected to the drive roller 21. A limiting mechanism that can limit the position of the alloy resistor is mounted on the driven roller 23.

[0028] The alloy resistor is clamped between the drive roller 21 and the driven roller 23. The motor 22 is started to drive the drive roller 21 to rotate. Under the action of friction, the driven roller 23 rotates and conveys the alloy resistor.

[0029] The limiting mechanism includes two sets of limiting rings 29, which are movably sleeved on the driven roller 23. Each set of limiting rings 29 is rotatably connected to a connecting ring 28 on the side away from each other. The connecting ring 28 is movably sleeved on the driven roller 23. Several sets of connecting rods 27 are fixedly connected to the side of the connecting ring 28 away from the limiting ring 29. A connecting plate 26 is fixedly connected to the end of the connecting rod 27 away from the connecting ring 28. The connecting plate 26 is movably sleeved on the driven roller 23. Several sets of telescopic rods 30 are fixedly connected to the side of the connecting plate 26 away from the connecting rods 27. The end of the telescopic rod 30 away from the connecting plate 26 is fixedly connected to the limiting frame 10. An adjustment mechanism for adjusting the distance between the two sets of limiting rings 29 is installed on the driven roller 23.

[0030] The adjustment mechanism includes two sets of sleeves 25. The sleeves 25 are movably sleeved on the driven roller 23. The end of the sleeve 25 near the connecting plate 26 is fixedly connected to the connecting plate 26. The sleeve 25 is threaded with a rotating cover 24. The end of the rotating cover 24 near the limit frame 10 is rotatably connected to the limit frame 10.

[0031] Rotating the rotating cover 24 causes the sleeve 25 to move, which in turn drives the connecting rod 27 to move via the connecting plate 26. This causes the connecting ring 28 and the limiting ring 29 to move, thereby adjusting the distance between the two sets of limiting rings 29. This allows the two sets of limiting rings 29 to clamp the alloy resistor on both sides, thus preventing the alloy resistor from shifting.

[0032] Several sets of guide sleeves 4 are fixedly connected to the bottom of the upper mold base 1, and several sets of guide posts 6 that match the guide sleeves 4 are fixedly connected to the top of the lower mold base 5. This facilitates the alignment of the upper mold base 1 and the lower mold base 5.

[0033] Working principle: In use, the alloy resistor is clamped between the drive roller 21 and the driven roller 23. Rotating the rotating cover 24 causes the sleeve 25 to move, which in turn moves the connecting rod 27 via the connecting plate 26, causing the connecting ring 28 and the limiting ring 29 to move. This allows adjustment of the distance between the two sets of limiting rings 29, ensuring that the two sets of limiting rings 29 clamp the alloy resistor on both sides, thus preventing displacement. Starting the motor 22 drives the drive roller 21 to rotate, and under the action of friction, the driven roller 23 rotates and conveys the alloy resistor, allowing it to pass through the material hole 13 on the die 8 and be located in the forming cavity 11. Then, the cylinder drives the upper die base 1 to descend, causing the punch 3 to descend and pass through the forming cavity 11. The mold block 12 stamps the alloy resistor. During normal stamping, the alloy resistor is always located between the pressure block 15 and the mounting base 17. The pressure block 15 is retracted in the mounting cover 14 under the constraint of the alloy resistor. If the alloy resistor is displaced from the limit mechanism during the stamping process, the pressure block 15 is not restricted. Under the action of the spring 16, the pressure block 15 moves downward and squeezes the pressure sensor 18. After receiving the pressure signal, the pressure sensor 18 immediately controls the machine to stop and issues an alarm signal to remind the operator to reset the alloy resistor. This enables real-time detection of the position of the alloy resistor in the mold during the stamping process, preventing the alloy resistor from shifting, ensuring product performance, and extending the service life of the mold.
