Description

Technical Field

[0001] This utility model relates to the field of resistance processing technology, and specifically to an alloy resistance processing and forming device. Background Technology

[0002] Existing alloy resistors have the following characteristics: they are made of copper and resistive alloy, and are formed into a whole by welding. Generally, through holes or blind holes of different sizes need to be machined on the copper end.

[0003] During the welding process of alloy resistors into strips, the weld joint between the copper and the resistor body is rough and uneven, affecting subsequent electroplating processes. Therefore, workers need to manually mill off the raised weld edges. However, the strip is relatively long, making it prone to misalignment during manual milling, requiring constant adjustments and affecting milling accuracy. Furthermore, flying debris can be inhaled by workers, impacting their health. Additionally, the strip is then sent for stamping into individual alloy resistors and hole machining; these two processes are performed at different stations, requiring secondary positioning, which not only reduces production efficiency but also affects the processing quality of the strip.

The driving component is used to synchronously drive the two pressing plates 21 to press the resistance strip 11 onto the positioning channel 41.

[0033] This invention uses a positioning channel 41 formed by two clamping plates 42 and a positioning fixture 4 to position the resistance strip 11. The driving component synchronously drives two pressure plates 21 to press the resistance strip 11 onto the positioning channel 41. While positioning the resistance strip 11, the flatness of the resistance strip 11 is ensured, thus ensuring milling accuracy and improving production efficiency. The two pressing components press and position the two ends of the resistance strip 11, providing support for both ends of the resistance strip 11 and preventing shaking during processing, further improving processing accuracy.

[0034] In one embodiment of this utility model, the driving assembly includes a driving cylinder 22, which is drivenly connected to a driving frame 292. A guide rod 26 is provided on the driving frame 292, and a guide sleeve 28 is provided on the machine base 1. The guide rod 26 passes through the guide sleeve 28 and is connected to the pressure plate 21. The driving cylinder 22 drives the driving rod to move up and down to realize the pressure plate 21 pressing and positioning the resistance strip 11.

[0035] Specifically, the drive cylinder 22 drives the drive rod to move downward, so that the anti-slip rubber layer 27 on the pressure plate 21 contacts and presses the resistance strip 11, thereby driving the pressure plate 21 to press and position the resistance strip 11 on the positioning fixture 4. While positioning the resistance strip 11, the flatness of the resistance strip 11 is ensured, the milling accuracy is ensured, and the production efficiency is improved.

[0036] In one embodiment of the present invention, the pressure plate 21 is provided with a waist-shaped groove 23, and a driving bolt is provided on the waist-shaped groove 23. The driving bolt passes through the waist-shaped groove 23 and is connected to the guide rod 26.

[0037] Specifically, the relative positions of the pressure plate 21 and the guide rod 26 are adjusted according to different resistance strips 11, so that the V-shaped opening 25 is changed to a suitable processing width. The drive bolt passes through the waist-shaped groove 23 and connects with the guide rod 26, thereby fixing the position of the pressure plate 21. It can be adapted to the processing of various specifications of resistance strips 11 and has a wide range of applications.

[0038] In one embodiment of the present invention, the clamping mechanism further includes a clamping cylinder 43, which is drivenly connected to two clamping plates 42, and there is a clamping gap between the two clamping plates 42. The clamping cylinder 43 drives the two clamping plates 42 to clamp and position both sides of the resistive strip 11.

[0039] Specifically, the resistance strip 11 is located in the positioning channel 41. The clamping cylinder 43 drives the two clamping plates 42 to clamp and position the two sides of the resistance strip 11, so that the resistance strip 11 is positioned in the positioning channel 41.

The guide rod 26 and the guide groove 44 work together to form a sliding guide structure, which can guide the movement of the clamping plate 42, ensure the movement accuracy of the clamping plate 42, and ensure that the clamping plate 42 clamps the two sides of the resistance strip 11 synchronously, thereby improving the clamping and positioning effect of the resistance strip 11.

[0042] In one embodiment of the present invention, the depth of the positioning channel 41 is less than or equal to the thickness of the resistive strip 11, and an anti-slip rubber layer 27 is provided on the pressing edge of the pressing plate 21.

[0043] Specifically, the depth of the positioning channel 41 is less than or equal to the thickness of the resistance strip 11, allowing the top of the resistance strip 11 to protrude through the positioning channel 41. Under the drive of the pneumatic actuator, the anti-slip rubber layer 27 on the pressure plate 21 contacts and presses against the resistance strip 11, thereby driving the pressure plate 21 to press and position the resistance strip 11 on the positioning fixture 4. This allows for accurate pressing operations on both sides of the resistance strip 11, ensuring the flatness of the resistance strip 11 and improving the positioning effect of the resistance strip 11.

[0044] In one embodiment of the present invention, the pressing edge of the pressing plate 21 is provided with an inclined surface 24, and the inclined surfaces 24 on the two pressing plates 21 form a V-shaped opening 25. The machine base 1 is provided with baffle plates 14 on both sides, and the baffle plates 14 are provided between the pressing assembly and the machine base 1. The baffle plates 14 are provided with guide grooves 15, and the guide grooves 15 are arranged opposite to the V-shaped openings 25.

[0045] Specifically, the V-shaped opening 25 formed by the inclined surface 24 on the two pressure plates 21 can expose the processing position of the resistance strip 11, which can facilitate the processing of the resistance strip 11. At the same time, the baffle plate 14 is set between the clamping assembly and the machine base 1. The baffle plate 14 is provided with a guide groove 15.

The pressing cylinder 32 drives the pressing plate 33 to press and position the resistance material strip 11 on the positioning groove 36.

[0047] Specifically, the two ends of the resistance strip 11 are respectively set on the two clamping mechanisms 3. The end of the resistance strip 11 is placed in the positioning groove 36 of the jig block 34. The clamping cylinder 32 drives the pressure plate 33 to clamp and position the resistance strip 11 on the positioning groove 36, thereby clamping and positioning the end of the resistance strip 11. This can provide support for both ends of the resistance strip 11, and at the same time prevent the resistance strip 11 from shaking during processing, thus improving the processing accuracy.

[0048] In one embodiment of the present invention, the pressure plate 33 is provided with a positioning pin 35, the positioning pin 35 is disposed opposite to the hole on the resistance strip 11, and the positioning groove 36 is provided with a clearance hole that matches the positioning pin 35.

[0049] Specifically, the completed resistor strip 11 (formed strip 12) has a hole that matches the positioning pin 35 for positioning. The positioning pin 35 passes through the hole to accurately position the resistor strip 11 and prevent the resistor strip 11 from shaking during processing. Depending on the actual situation, the unprocessed resistor strip 11 (unprocessed strip 13) does not need to be equipped with positioning pin 35 because it does not have a corresponding hole.

[0050] In one embodiment of this utility model, the machine base 1 is provided with a guide hole 291, a guide sleeve is provided on the guide hole 291, the free end of the guide rod 26 passes through the guide sleeve, and the drive frame 292 is connected to the guide rod 26 by a clamp 29.

[0051] Specifically, the drive frame 292 and the guide rod 26 are detachably connected by a clamp 29. The clamping position of the drive frame 292 and the guide rod 26 can be adjusted according to the different thicknesses of the resistance strip 11, thereby adjusting the up and down movement of the clamping plate 42. This has a wide range of applications. At the same time, the free end of the guide rod 26 passes through the guide sleeve, which can cooperate with the guide sleeve 28 to guide and position the guide rod 26 on both sides, ensuring the movement accuracy of the pressure plate 21, ensuring the precise positioning of the resistance strip 11, and ensuring its processing accuracy.

[0052] Usage process

[0053] The resistance strip 11 is placed on the positioning fixture 4, which supports the resistance strip 11, and the resistance strip 11 is located in the positioning channel 41. The clamping cylinder 43 drives the two clamping plates 42 to clamp and position the two sides of the resistance strip 11, so that the resistance strip 11 is positioned in the positioning channel 41. The drive cylinder 22 drives the drive rod to move downward, so that the anti-slip rubber layer 27 on the pressure plate 21 contacts and presses the resistance strip 11, thereby driving the pressure plate 21 to press and position the resistance strip 11 on the positioning fixture 4. At the same time, the V-shaped opening 25 formed by the inclined surface 24 on the two pressure plates 21 can expose the processing position of the resistance strip 11. The two ends of the resistance strip 11 are respectively set on the two pressing mechanisms 3. The resistor strip 11 is placed in the positioning groove 36 of the fixture block 34. The clamping cylinder 32 drives the pressure plate 33 to clamp and position the resistor strip 11 on the positioning groove 36, thereby clamping and positioning the resistor strip 11 at the end. The device is placed on the machining bed, and the resistor machining program is started. After the resistor strip 11 is milled and drilled, the clamping drive cylinders are closed in sequence, the upper and lower pressure plates 21 are released, the left and right parallel A plan is released, and the front and rear lower pressure plates 33 are also opened. The completed resistor strip 11 continues to be transferred to the next process. At the same time, the unprocessed part of the resistor strip 11 begins to be transported to the milling and drilling station, and the lower wheel can be opened to mill and drill again. This process is repeated to complete the rapid processing of the resistor strip 11, which has high processing efficiency.
