Description

Technical Field

[0001] The invention relates to the technical field of shearing equipment, in particular to a shearing device for processing circuit breaker capacitor parts. Background Art

[0002] Circuit breaker capacitors usually refer to capacitors used in circuit breakers. This type of capacitor is mainly used to improve the operating performance of circuit breakers or protect circuit breakers from transient voltages. Circuit breaker capacitors have pins. If the pins are too long, the connection will be loose during installation. Therefore, during the processing of circuit breaker capacitors, the pins on the capacitor that are too long need to be cut to ensure that they are installed firmly.

[0003] At present, the pin cutting operation of circuit breaker capacitors is mainly completed by a pin cutting machine. The working principle of the pin cutting machine is to press the capacitor to fix it on the workbench through a downward pressure mechanism, and then cut off the excessively long pins on the capacitor through a cutter. Although the existing pin cutting machines can cut the pins of capacitors, the existing pin cutting machines are designed to either support the cutting operation of a single row of pins or the cutting operation of a double row of pins. It is difficult to flexibly switch between the cutting operation of a single row of pins and the cutting operation of a double row of pins. It lacks flexibility and is difficult to meet the needs of supporting the cutting operation of both single row of pins and double row of pins. This results in the factory needing to purchase multiple types of pin cutting machines to cope with different types of capacitors, which not only increases the equipment investment cost, but also makes the equipment utilization rate low.

[0030] See also Figure 4-Figure 6 The adjustment mechanism includes a guide rail 81 connected to the lower left part of the workbench 2, a sliding block 82 is slidably provided in the guide rail 81, a group of steel balls 83 is slidably provided on the left side of the sliding block 82, two steel balls 83 form a group, the two steel balls 83 are symmetrically arranged up and down, a support spring is connected between the steel balls 83 and the sliding block 82, and two groups of grooves 84 that fit the steel balls 83 are spaced apart on the front inner wall of the guide rail 81, the number of each group of grooves 84 is two, the two grooves 84 in each group are symmetrically arranged up and down, and the shape of the grooves 84 is hemispherical The sliding block 82 is provided with an adjusting member for adjusting the spacing between the two support plates 6, and the adjusting member includes a threaded rod 85 threadedly connected to the sliding block 82, and the rear end of the threaded rod 85 is connected to an outer diamond rod 86, and an inner diamond rod 87 is slidably sleeved on the outer diamond rod 86, and the inner diamond rod 87 extends between the two support plates 6 and is connected to a connecting plate 88, and the connecting plate 88 is hinged to the two support plates 6, and guide grooves are provided on the workbench 2 and the guide rail 81, and the guide grooves are used to guide the movement of the threaded rod 85, the outer diamond rod 86 and the inner diamond rod 87.

[0031] By rotating the bidirectional screw rod 71, the spacing between the two connecting plates 72 can be adjusted to adjust the spacing between the two support plates 4. By rotating the bidirectional screw rod 73, the spacing between the two connecting plates 74 can be adjusted to adjust the spacing between the two guide plates 3. The spacing between the two guide plates 3 and the spacing between the two support plates 4 are adjustable to adapt to capacitors 16 of different sizes, thereby increasing the versatility and flexibility of the device and having a wide range of applications. If the pins of the capacitor 16 with a single row of pins are to be cut, the threaded rod 85 is pushed backward to drive the sliding block 82 to move backward, and the steel ball 83 on the sliding block 82 is squeezed by the semicircular groove 84 on the guide rail 81, and the steel ball 83 moves out of the groove 84 to the right and compresses the support spring, and the threaded rod 85 moves backward through the outer diamond rod 86 to push the inner diamond rod 87 to move the connecting plate 88 backward, and the connecting plate 88 moves backward to drive the two supporting plates 2 6 to move backward synchronously, so that the front supporting plate 2 6 is located at the rear side of the pins of the capacitor 16 with a single row of pins, so that the pins of the capacitor 16 with a single row of pins are supported by the front supporting plate 2 6, so that the front side cutter 93 can cut the pins of the capacitor 16 with a single row of pins in the subsequent operation. When the supporting plate 2 6 moves horizontally, the sliding plate 92 is driven to move horizontally synchronously through the telescopic mounting frame 91, thereby driving the cutter 93 to move horizontally, ensuring that the distance between the cutter 93 and the supporting plate 2 6 on the same side is always consistent, so as to ensure that the cutter 93 can accurately cut off the excessively long pins on the capacitor 16 in the subsequent operation. When the steel ball 83 moves backward to align with the groove 84 on the rear side, under the reset action of the support spring, the steel ball 83 can be pushed to move to the left and snap into the groove 84 on the rear side to lock the sliding block 82, thereby locking the support plate 26 to prevent the movement of the support plate 26 from affecting the pin cutting operation of the capacitor 16. The adjusting screw 914 can be turned to move the adjusting screw 914 up and down, so that the T-shaped slide rail 912 can drive the upper part thereof to move up and down to adjust the height of the cutter 93. The adjustable height of the cutter 93 can meet the requirements of the pin cutting operation of capacitors 16 of different specifications, so as to cut out pins of appropriate length, ensuring that the pins of each capacitor 16 can accurately meet the requirements, further increasing the versatility and flexibility of the device, and having a wider range of applications.

[0032] When performing the pin cutting operation of the single-row pin capacitor 16, the single-row pin capacitor 16 is conveyed to the left between the front and rear guide plates 3 by the feeder, and the front capacitor 16 is pushed to the left by the rear capacitor 16 to realize the conveyance of the capacitor 16. The capacitor 16 is guided by the guide plate 3 to prevent the capacitor 16 from shifting forward and backward. The main body of the capacitor 16 can be supported by the support plate 2 6 to prevent the capacitor 16 from falling downward. The cylinder 52 can drive the pressing plate 53 to move reciprocatingly downward and upward. After the pressing plate 53 moves downward, it presses the capacitor 16 and fixes it on the supporting plate 6 to avoid displacement of the capacitor 16 when the subsequent cutter 93 cuts the pins, ensuring accurate cutting of the pins of the capacitor 16. The front motor 95 is controlled to drive the driving wheel 96 thereon to rotate, so that the front frame 94 can be pushed to drive the front cutter 93 to move reciprocatingly back and forth through the front slide 92. The front cutter 93 reciprocates back and forth to cut a single row of pins of the capacitor 16. The cut pins are discharged downward through the discharge port 23. A collection frame is placed below the discharge port 23 to collect the waste pins.

[0033] When the pins of a double-row capacitor 16 are to be cut, the threaded rod 85 is pushed forward to drive the sliding block 82 forward, so that the two support plates 6 move forward to between the double-row pins of the capacitor 16, and the steel ball 83 is then inserted into the groove 84 on the front side. The threaded rod 85 is rotated to drive the outer diamond rod 86 to drive the inner diamond rod 87 to rotate, and the connecting plate 88 rotates accordingly to push the two support plates 6 away from each other, so that the two support plates 6 respectively support the double-row pins on the capacitor 16, so that the subsequent cutter 93 can cut the pins of the double-row pin capacitor 16. The spacing between the two support plates 6 is adjustable to adapt to double-row pin capacitors 16 of different specifications. By controlling the motors 95 on both sides to work simultaneously, the two cutters 93 can be driven to move back and forth synchronously in the direction of approaching and moving away from the support plate 6, thereby realizing the shearing of the double-row pins of the capacitor 16. In this way, the device can flexibly switch between the single-row pin shearing operation and the double-row pin shearing operation, showing high flexibility and wide applicability, thereby being able to meet the cutting operation requirements of supporting both single-row pins and double-row pins. Therefore, the factory does not need to purchase multiple types of pin shearing machines to cope with different types of capacitors 16, which not only reduces the investment cost of the equipment, but also improves the utilization rate of the equipment.

[0034] See also Figure 9-10The tops of the two guide plates 3 are slidably connected to a push plate 11 that can reciprocate left and right through a slide groove. A telescopic sleeve 12 is connected to the right side of the push plate 11. The right end of the telescopic sleeve 12 is fixedly connected to the right end surface of the slide groove on the guide plate 3. A return spring 13 located in the telescopic sleeve 12 is connected between the push plate 11 and the guide plate 3. A push rod 10 is connected to the right side of the pressure plate 53. The push plate 11 is L-shaped, and a slope is provided on the left side of the push plate 11. When the push rod 10 moves down and contacts the slope on the push plate 11, it can squeeze the slope on the push plate 11, thereby pushing the push plate 11 to move to the right.

[0035] When the pressing plate 53 moves downward to press and fix the capacitor 16 in the area directly below it, the push rod 10 is driven downward, and the two front and rear push plates 11 are pushed to the right by the downward movement of the push rod 10. The reset spring 13 is compressed accordingly, and the two push plates 11 move to the right to push the capacitor 16 located in the right area of ​​the pressing plate 53 to the right, so that a certain space is reserved on the right side of the pressing plate 53 to avoid collision or accumulation of the newly added capacitor 16 with the fixed capacitor 16 and the pressing plate 53, thereby preventing the material from being stuck, so as to improve the reliability and stability of the equipment, ensure the continuity of the shearing operation, and thus improve the overall production efficiency. After the push rod 10 follows the pressing plate 53 to move upward and separates from the push plate 11, under the reset action of the reset spring 13, the push plate 11 is pushed to move to the left to reset, thereby pushing the capacitor 16 located between the two push plates 11 to the left.

[0036] See also Fig. 9 A guide plate 14 is connected to the left side of the workbench 2, and an elastic material guide plate 15 made of silicone material is connected to the left side of the guide plate 14. The elastic material guide plate 15 made of silicone material has excellent flexibility and elasticity, can be deformed when subjected to force, and maintain a stable shape when not subjected to force.

[0037] The cut capacitors 16 can be guided downward by the guide plate 14 and the elastic guide plate 15. A collection frame is placed under the elastic guide plate 15 to collect the cut capacitors 16. According to actual conditions, the elastic guide plate 15 can be bent up and down to adjust the downward tilt of the elastic guide plate 15. In this way, the cut capacitors 16 can fall smoothly into the collection frame, thereby reducing the risk of damage to the capacitors 16.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
