[0026] Such as Figures 1 to 5As shown in the figure, a shearing device includes a bracket 1. A placement mold 4 for placing diodes is inserted into the bracket 1. A limiting mechanism 5 for limiting the placement mold 4 is arranged on the bracket 1. Two fixing bases 6 for fixing are arranged at the bottom of the bracket 1. Distance-adjusting mechanisms 3 for adjusting the shearing distance are arranged on both sides of the bracket 1. A pressing and shearing mechanism 2 for assisting in pressing and fixing the diode leads and shearing them is arranged on the bracket 1. The pressing and shearing mechanism 2 is connected to the distance-adjusting mechanism 3. Specifically, first, the device is fixedly installed through the fixing bases 6. Then, the diode to be processed is placed on the placement mold 4. Subsequently, the placed placement mold 4 is inserted into the bracket 1. The replaceable placement mold 4 enables the same device to be applicable to the production of diodes of different models and sizes, improving the flexibility and versatility of the device. At the same time, the limiting mechanism 5 is used to limit the placement mold 4 to prevent it from slipping off. Then, the distance of the distance-adjusting mechanism 3 is adjusted according to the required shearing lengths on both sides. Subsequently, the pressing and shearing mechanism 2 descends to press the diode on the placement mold 4 to prevent its displacement, and at the same time shear its leads. By adjusting the distance-adjusting mechanism 3 to drive the pressing and shearing mechanism 2 to adjust the position, precise control of the lead length shearing can be achieved, reducing subsequent use problems caused by inconsistent lead lengths, improving the product quality, enabling the device to adapt to the shearing of leads with different length requirements on both sides, increasing the versatility and flexibility of the device. The design of shearing both sides simultaneously reduces the time required for shearing a single lead and improves the overall production efficiency.

[0027] As Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, the distance adjustment mechanism 3 includes a first limit post 301, an adjustment screw post 302 and a second limit post 303. The adjustment screw post 302 is rotatably installed on both side walls of the bracket 1. On both side walls of the bracket 1 above and on one side of the two groups of adjustment screw posts 302, the first limit post 301 and the second limit post 303 are fixedly arranged. L-shaped mounting plates 306 are threadedly connected to the two groups of adjustment screw posts 302. The L-shaped mounting plates 306 are slidably arranged with the first limit post 301 and the second limit post 303. A fixed block 3010 is fixedly installed at the top of one side of the L-shaped mounting plate 306. A sliding groove 305 is formed in the fixed block 3010. A sliding block 304 is slidably arranged in the sliding groove 305. The sliding block 304 is connected to the pressing and shearing mechanism 2. Mounting frames 307 are fixedly installed at the tops of the two groups of fixed blocks 3010. A telescopic rod 309 is rotatably installed on one group of mounting frames 307. The free end of the telescopic rod 309 is rotatably connected to a connecting rod 308. The bottom of the connecting rod 308 is rotatably arranged with the other group of mounting frames 307. Specifically, by adjusting the two groups of adjustment screw posts 302 according to the required shearing lengths of the pins on both sides, the L-shaped mounting plate 306 drives the pressing and shearing mechanism 2 at the bottom to move. At the same time, during the movement, the first limit post 301 and the second limit post 303 play an auxiliary role to improve the stability of the device. Subsequently, the fixed block 3010 on the L-shaped mounting plate 306 synchronously drives the pressing and shearing mechanism 2 to displace. At the same time, the mounting frame 307 at the top pulls the telescopic rod 309 to expand and rotate so that it can adapt to different required lengths. The sliding block 304 sliding in the sliding groove 305 on the fixed block 3010 drives the pressing and shearing mechanism 2 to slide, improving the stability of the pressing and shearing mechanism 2 during shearing. At the same time, when the L-shaped mounting plate 306 drives the fixed block 3010 to move, it synchronously drives the pressing and shearing mechanism 2 to adjust.

[0028] As Figure 2 , Figure 3 , Figure 5As shown in the figure, the pressing and shearing mechanism 2 includes an electric push rod 201, a sliding sleeve 204 and a lower blade 2011. The electric push rod 201 is fixedly installed at the center of the top of the bracket 1. The sliding sleeve 204 is fixedly installed on the sliding block 304. The lower blade 2011 is installed on the top of the L-shaped mounting plate 306. The telescopic end of the electric push rod 201 penetrates through one side wall of the bracket 1 and is fixedly connected with a mounting block 202. Fixed rods 203 are fixedly arranged on both side walls of the mounting block 202. The fixed rods 203 are slidably arranged with the sliding sleeve 204. An upper blade 2010 is installed at the bottom of the sliding sleeve 204. A perforated plate 205 is fixedly installed at the bottom of the mounting block 202. Two groups of sliding rods 208 are slidably arranged on the perforated plate 205. The bottoms of the two groups of sliding rods 208 are fixedly connected with a fixing plate 206. A rubber pad 207 is arranged at the bottom of the fixing plate 206. Springs 209 are arranged on the sliding rods 208 between the opposite surfaces of the perforated plate 205 and the fixing plate 206. Specifically, the translation of the fixed block 3010 drives the sliding block 304, so that the sliding sleeve 204 drives the upper blade 2010 to slide along the fixed rod 203, which is convenient for adjusting the position of the upper blade 2010. And the lower blade 2011 on the bottom L-shaped mounting plate 306 is displaced synchronously with the upper blade 2010, which simplifies the operation and is convenient for shearing operations. After the adjustment is completed, the electric push rod 201 descends to drive the mounting block 202, so that the fixing plate 206 and the rubber pad 207 press and fix the diode on the placement mold 4, improving the stability during diode shearing. At the same time, the rubber pad 207 avoids damaging the diode. And after the fixing plate 206 and the rubber pad 207 contact the diode, the sliding rods 208 on the fixing plate 206 slide along the perforated plate 205. And due to the elastic force of the spring 209, it avoids damage to the diode caused by hard extrusion contact. The fixed rod 203 on the mounting block 202 drives the upper blade 2010 on the sliding sleeve 204 to continue to press down to shear the lead. By adjusting the distance adjustment mechanism 3 to drive the pressing and shearing mechanism 2 to adjust the position, precise control of the lead length shearing can be achieved, reducing subsequent use problems caused by inconsistent lead lengths, improving product quality, enabling the device to adapt to lead shearing requirements of different lengths on both sides, increasing the versatility and flexibility of the equipment. And the design of shearing both sides simultaneously reduces the time required for shearing a single lead, improving the overall production efficiency.

[0029] As Figure 2 , Figure 3As shown, the height of the fixing plate 206 is greater than the height of the upper blade 2010, and the height of the lower blade 2011 is lower than the height of the placement mold 4. Specifically, the fixing plate 206 and the rubber pad 207 are higher than the upper blade 2010, which facilitates the auxiliary pressing of the diode by the fixing plate 206 and the rubber pad 207, avoids the displacement of the diode during shearing, prevents the shearing length from not meeting the standard, improves the product quality, and the lower blade 2011 being lower than the placement mold 4 facilitates the parallel placement of the pins and subsequent shearing operations.

[0030] As Figure 4 shown, the limiting mechanism 5 includes a fixing stud 501 and an L-shaped limiting block 504. The fixing stud 501 is fixedly installed on one side wall of the bracket 1, and the L-shaped limiting block 504 is fixedly installed on the lower side of the fixing stud 501. A butterfly-shaped limiting block 503 is sleeved on the fixing stud 501, and a fastening nut 502 is threadedly connected to the fixing stud 501 outside the butterfly-shaped limiting block 503. Specifically, when the placement mold 4 needs to be placed, the fastening nut 502 on the fixing stud 501 is loosened, and then the butterfly-shaped limiting block 503 is rotated to be in a fitting state with the bottom side of the L-shaped limiting block 504. At this time, the placement mold 4 is inserted into the bracket 1, and then the butterfly-shaped limiting block 503 is rotated to be in a fitting state with the top of the L-shaped limiting block 504, and the fastening nut 502 is tightened at the same time to fix the butterfly-shaped limiting block 503, so that the butterfly-shaped limiting block 503 quickly limits the placement mold 4 and avoids sliding during shearing, improving the shearing quality.

[0031] As Figure 2 、 Figure 3 shown, a fixing slide bar 7 is fixedly arranged on the bracket 1, and the fixing slide bar 7 is slidably arranged with the placement mold 4. Specifically, the placement mold 4 is limited by the fixing slide bar 7 on the bracket 1, making the placement mold 4 more stable after being inserted, and further improving the quality during shearing.

[0032] In summary: First, the device is fixedly installed through the fixed base 6. Subsequently, the diode to be processed is placed on the placement mold 4. Then, the placed placement mold 4 is inserted into the bracket 1. The replaceable placement mold 4 enables the same device to be applicable to the production of diodes of different models and sizes, improving the flexibility and versatility of the device. At the same time, the limiting mechanism 5 is used to limit the placement mold 4 to prevent it from slipping. Then, the distance of the distance adjustment mechanism 3 is adjusted according to the required shearing lengths on both sides. Subsequently, the shearing mechanism 2 is pressed to descend to press the diode on the placement mold 4 to prevent its displacement, and at the same time, its pins are sheared. By adjusting the distance adjustment mechanism 3 to drive the pressing and shearing mechanism 2 to adjust the position, precise control of the pin length shearing can be achieved, reducing subsequent use problems caused by inconsistent pin lengths, improving the product quality, enabling the device to adapt to the shearing of pins with different length requirements on both sides, increasing the versatility and flexibility of the device, and the design of simultaneous shearing on both sides reduces the time required for single-pin shearing, improving the overall production efficiency.
