Description

Technical Field

[0001] This invention relates to the field of circuit breaker component processing technology, specifically to a punching device for processing circuit breaker components. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal or abnormal circuit conditions. Circuit breakers are important electrical devices for the protection and operation of power systems. They can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. Circuit breakers come in many structures and types, but they are basically composed of a conductive main circuit, insulating support components, an arc-extinguishing chamber, and an operating mechanism. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. When processing circuit breaker base accessories, punching equipment is often used to punch them. As an important component of the circuit breaker, the outer edge area of ​​the base needs to be punched to ensure that the dimensions of the circuit breaker base meet the actual assembly requirements.

[0003] When existing punching equipment processes the outer edge area of ​​the circuit breaker base, the contact surface deforms during punching, resulting in burrs at the punching position, which affects the subsequent processing accuracy. In addition, during the punching process, additional fixing measures are often required to fix the circuit breaker base, which increases the overall punching process and affects the overall processing efficiency.

[0019] This invention provides a punching device for processing circuit breaker components. It has the following advantages:

[0020] I. This punching device for processing circuit breaker components conveys circuit breaker base components through a feeding mechanism and supports the circuit breaker base using an unloading and cutting mechanism. During punching, the front contact of the auxiliary fixing mechanism provides auxiliary fixation for the circuit breaker base. Then, the upper punching and cutting blade assembly and the lower punching and cutting blade work together to remove excess edge material from the circuit breaker base. Simultaneously, the contact between the upper punching and cutting blade assembly and the punching position of the circuit breaker base during the descent and ascent of the upper punching and cutting blade assembly scrapes and grinds the punching position, thereby removing burrs and improving the punching quality of circuit breaker components.

[0021] 2. This punching device for processing circuit breaker accessories uses a hydraulic power module and a punching lifting rod to drive the connecting plate and the knife holder to descend. An auxiliary fixing mechanism is used to fix the circuit breaker base placed on the punching seat. Then, the cutting blade head and the lower punching blade work together to punch the edge of the circuit breaker base. At the same time, the fixing plate and the scraping plate scrape the punched edge of the circuit breaker base to remove burrs, thereby ensuring the utilization efficiency of the equipment.

[0022] Third, the punching device for processing circuit breaker accessories uses the lowering of the connecting plate to drive the limit protection component and the adjustment component to descend, so that the bonding and fixing component contacts the surface of the circuit breaker base. The downward driving pressure makes the soft bonding pad make tight contact with the surface of the circuit breaker base. In addition, the soft material properties of the soft bonding pad and the fixing of the hard base increase the friction of the contact surface, further ensuring the fixing effect.

[0023] IV. This punching device for processing circuit breaker accessories uses a soft bonding pad to contact the circuit breaker base, which in turn pushes the pressure plate and the rigid seat top support plate, causing the slider to slide in the adjustment groove and compress the spring plate to deform. The deformation space of the spring plate is combined with the buffer adjustment space required for the soft bonding pad to contact, avoiding excessive pressure from direct contact that could damage the circuit breaker base, thereby improving the efficiency of the equipment and further reducing the defect rate.

[0024] 5. This punching device for processing circuit breaker accessories, through the elastic force of the compression spring and the sliding of the top pressure rod in the outer sleeve, reserves a buffer space. It works in conjunction with the adjustment component and the fitting and fixing component to provide multi-level protection. While ensuring the fixing effect, it leaves a safe buffer space. In addition, the setting of the limit sleeve and the connecting plate is used to provide limit support and ensure the safe use of the overall component.

[0025] VI. This punching device for processing circuit breaker components, driven by a cylinder and pushed down by a push plate, can push the punched circuit breaker base off the punching seat, reducing the frequency of contact between the operator and the punching tool, avoiding safety accidents. The mechanized unloading operation is more efficient. In addition, the setting of the limit baffle, in conjunction with the push plate, can achieve a limiting effect, ensuring the locking and positioning effect of the circuit breaker base on the punching seat. At the same time, the setting of rollers makes the movement of the limit baffle more labor-saving, ensuring the unloading efficiency of the processed circuit breaker base.

[0038] First embodiment, such as Figures 1 to 10 As shown, the present invention provides a technical solution: a punching device for processing circuit breaker components, comprising:

[0039] Frame 1, which has a worktable for support;

[0040] The feeding mechanism 2 and the conveying mechanism 3 are used to convey circuit breaker base accessories. The feeding mechanism 2 and the conveying mechanism 3 are fixedly installed on the outside of the workbench. It should be noted that the feeding mechanism 2 and the conveying mechanism 3 include the outer frame, rotating rollers, conveyor belt, drive motor, etc., but are not limited to these.

[0041] A punching mechanism 4 is used to punch the circuit breaker base. The punching mechanism 4 is fixedly installed on the top of the worktable. It includes a drive assembly, an upper punching blade assembly 44, and a lower punching blade 45. The upper punching blade assembly 44 and the lower punching blade 45 are used to remove excess edge material from the circuit breaker base. The drive assembly is fixedly installed on the top of the worktable, the upper punching blade assembly 44 is fixedly installed at the output end of the drive assembly, and the lower punching blade 45 is located below the upper punching blade assembly 44. A material unloading and cutting seat mechanism 6 is fixedly installed on the top of the worktable below the drive assembly, and the lower punching blade 45 is detachably installed outside the material unloading and cutting seat mechanism 6. The drive assembly includes a hydraulic power module 41 fixedly installed on the top of the worktable. It should be noted that the hydraulic power module 41 includes a hydraulic pump. The circuit breaker base is composed of hydraulic control valves, hydraulic actuators, hydraulic auxiliary components, etc., but is not limited to these.

The output end of the hydraulic power module 41 is fixedly connected to a punching lifting rod 42, and the bottom of the punching lifting rod 42 is fixedly connected to a connecting plate 43. The unloading cutting seat mechanism 6 supports the circuit breaker base, and the hydraulic power module 41 provides driving force to make the punching lifting rod 42 and the connecting plate 43 descend. The descent of the upper punching cutter assembly 44 cooperates with the lower punching cutter 45 to punch the excess edge material of the circuit breaker base. The upper punching cutter assembly 44 contacts the punching position of the circuit breaker base during the descent and ascent to scrape the punching position and remove the burrs.

[0042] The punching device for processing circuit breaker components also includes:

[0043] The auxiliary fixing mechanism 5 is fixedly installed at the bottom of the drive assembly and is used to assist in fixing the circuit breaker base. The auxiliary fixing mechanism 5 includes a limiting protection component 51 fixedly installed at the bottom of the drive assembly. An adjusting component 52 is fixedly connected to the bottom of the limiting protection component 51. An engaging fixing component 53 for engaging and fixing the circuit breaker base is movably connected to the outside of the adjusting component 52. During stamping, the front contact of the engaging fixing component 53 is used to assist in fixing the circuit breaker base, and a buffer space is provided by the limiting protection component 51 and the adjusting component 52.

[0044] During operation, the circuit breaker base assembly to be punched is transported to the workbench by the feeding mechanism 2. Then, the operator places the circuit breaker base on the unloading and cutting mechanism 6, which supports the circuit breaker base. The equipment is then started, and the hydraulic power module 41 drives the punching lifting rod 42 and the connecting plate 43 to descend, causing the auxiliary fixing mechanism 5 to descend. The fitting fixing component 53 contacts the circuit breaker base and fixes it. At the same time, the limit protection component 51 and the adjustment component 52 provide protection during fixing. Then, the upper punching and cutting blade assembly 44 descends and cooperates with the lower punching and cutting blade 45 to punch off the edge material of the circuit breaker base. The upper punching and cutting blade assembly 44 scrapes the punched area to remove the burrs. After the circuit breaker base punching and processing is completed, the finished product is transported off by the conveying mechanism 3.

[0045] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 2 to 6 As shown, the upper punching and cutting blade assembly 44 includes a blade holder 441 fixedly connected to the bottom surface of the connecting plate 43. A cutting blade head 442 is detachably installed at the bottom of the blade holder 441. A fixing plate 443 is fixedly connected to the inner wall of one side of the cutting blade head 442. Several equally spaced scraping plates 444 are fixedly connected to the inner wall of the fixing plate 443. It should be noted that the surfaces of the fixing plate 443, the scraping plates 444 and the cutting blade head 442 are on the same plane and flush. The scraping plates 444 are used to scrape and grind the punching edge of the circuit breaker base to remove burrs. The cutting blade head 442 cooperates with the lower punching and cutting blade 45 to punch and cut the edge of the circuit breaker base. The fixing plate 443 and the scraping plates 444 are used to scrape and grind the punching edge of the circuit breaker base to remove burrs.

[0046] A fixed base 46 is fixedly connected to the bottom of the end of the hydraulic power module 41 away from the punching lifting rod 42. The bottom of the fixed base 46 is fixedly connected to the top of the worktable. A guide seat is slidably connected to the top of the outer surface of the fixed base 46, and one end of the guide seat is fixedly connected to the outer surface of the punching lifting rod 42. The guide seat limits the punching lifting rod 42 to ensure the stability of the punching lifting rod 42 when it is raised and lowered.

[0047] The unloading and cutting mechanism 6 includes a punching seat 61 fixedly installed on the top of the workbench. The punching seat 61 is used to support the circuit breaker base and is located below the fitting and fixing assembly 53. The outside of the punching seat 61 is slidably connected to the unloading assembly 62 for assisting unloading. The lower punching blade 45 is movably inserted into the outer surface of the punching seat 61.

[0048] The unloading assembly 62 includes a cylinder 621 fixedly connected to the outer surface of the fixed base 46. A push plate 622 is fixedly connected to the output shaft of the cylinder 621 and slidably connected to the top of the punching base 61. Limiting baffles 623 are fixedly connected to both sides of the push plate 622, and the inner side of the limiting baffles 623 is slidably connected to the outer surface of the punching base 61. Driven by the cylinder 621, the circuit breaker base punched on the punching base 61 is pushed down by the push plate 622. The limiting baffles 623 cooperate with the push plate 622 to achieve a limiting effect, ensuring that the circuit breaker base is locked and positioned on the punching base 61.

[0049] A groove 63 is provided on the outer surface of the punching seat 61. The inner bottom end of the limiting baffle 623 is slidably connected to the inner wall of the groove 63. A roller 624 is rotatably connected to the inner bottom end of the limiting baffle 623. The outer surface of the roller 624 is slidably connected to the inner wall of the groove 63. By utilizing the sliding of the limiting baffle 623 in the groove 63 and the sliding of the roller 624 in the groove 63, the limiting baffle 623 can move with less effort.

[0050] During operation, the circuit breaker base is supported by the punching seat 61. The edge of the circuit breaker base is punched off by the cooperation of the knife holder 441 and the lower punching knife 45. At the same time, the scraping plate 444 is used to scrape and grind the punched edge of the circuit breaker base to remove burrs. After the circuit breaker base punching is completed, the cylinder 621 is started. The cylinder 621 drives the push plate 622 to move on the punching seat 61 and push the punched circuit breaker base down. Then, the material conveying mechanism 3 is used to transport and store the finished circuit breaker base.

[0051] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 10 As shown, the limiting protection component 51 includes an outer sleeve 511 fixedly connected to the bottom of the connecting plate 43. A top pressure rod 512 is slidably connected to the inner surface of the outer sleeve 511, and a compression spring 515 is fixedly connected to the top of the top pressure rod 512. The top of the compression spring 515 is fixedly connected to the bottom surface of the connecting plate 43. A connecting plate 514 is fixedly connected to the bottom of the top pressure rod 512. A limiting sleeve rod 513 fixedly connected to the top of the connecting plate 43 is fixedly connected to the top of the connecting plate 43. Through the elastic force of the compression spring 515 and the sliding of the top pressure rod 512 in the outer sleeve 511, a buffer space is reserved. In conjunction with the adjusting component 52 and the fitting and fixing component 53, multi-level protection is provided to ensure the fixing effect and leave a safe buffer space. It should be noted that the limiting sleeve rod 513 is composed of a sleeve rod and a sliding rod that slides inside the sleeve rod.

[0052] The adjusting assembly 52 includes a connecting seat 521 fixedly connected to the bottom of the top pressure rod 512. An adjusting groove 522 is provided on the outer surface of the connecting seat 521. A spring-loaded bending plate 523 is fixedly connected to the top of the inner cavity of the adjusting groove 522. A slider 524 is fixedly connected to the bottom of the spring-loaded bending plate 523. The outer surface of the slider 524 is slidably connected to the inner wall of the adjusting groove 522. A supporting bending plate 525 is hinged to the outer surface of the slider 524. One end of the supporting bending plate 525 is fixedly connected to the top of the fitting and fixing assembly 53. Through the contact between the fitting and fixing assembly 53 and the circuit breaker base, the supporting bending plate 525 is pushed in the opposite direction, so that the slider 524 slides in the adjusting groove 522, which compresses the spring-loaded bending plate 523 to deform. With the deformation space of the spring-loaded bending plate 523, the soft fitting pad 533 is provided with the buffer adjustment space required for contact, so as to avoid excessive pressure from direct contact and damage to the circuit breaker base.

[0053] The bonding and fixing assembly 53 includes a pressure plate 531 disposed outside the connecting seat 521. The end of the supporting bent plate 525 away from the slider 524 is fixedly connected to the top of the pressure plate 531. Several equally spaced rigid seats 532 are fixedly connected to the outer surface of the pressure plate 531. A soft bonding pad 533 is fixedly connected to the bottom surface of the rigid seat 532. The lowering of the connecting plate 43 drives the limiting protection assembly 51 and the adjusting assembly 52 to descend, so that the soft bonding pad 533 contacts the surface of the circuit breaker base. The downward driving pressure makes the soft bonding pad 533 make tight contact with the surface of the circuit breaker base. The soft material properties of the soft bonding pad 533 and the fixing of the rigid seat 532 increase the friction of the contact surface.

[0054] During operation, the connecting plate 43 descends, causing the outer sleeve 511 and connecting seat 521 to descend as well. This allows the soft bonding pad 533 to contact the surface of the circuit breaker base. The downward driving pressure ensures that the soft bonding pad 533 is in close contact with the surface of the circuit breaker base, increasing the friction of the contact surface and fixing the circuit breaker base. Simultaneously, the pressure plate 531 pushes the support bending plate 525 in the opposite direction, causing the slider 524 to slide in the adjustment groove 522. This causes the spring bending plate 523 to deform, and the deformation space of the spring bending plate 523 provides the necessary buffer adjustment space for the soft bonding pad 533 to contact the base. Furthermore, the elastic force of the compression spring 515 and the sliding of the top pressure rod 512 in the outer sleeve 511 provide buffer space. This multi-level protection ensures a safe buffer space and guarantees the effective fixing of the circuit breaker base.

[0055] The working principle of this punching device for processing circuit breaker components will be explained in detail below.

[0056] In operation, the circuit breaker base assembly to be punched is conveyed to the worktable by the feeding mechanism 2. Then, the operator places the circuit breaker base on the unloading and cutting mechanism 6. The punching seat 61 supports the circuit breaker base. The equipment is started, and the hydraulic power module 41 drives the punching lifting rod 42 and the connecting plate 43 to descend, causing the auxiliary fixing mechanism 5 to descend. The descent of the connecting plate 43 also drives the outer sleeve 511 and the connecting seat 521 to descend, so that the soft bonding pad 533 contacts the surface of the circuit breaker base. The downward driving pressure makes the soft bonding pad 533 make tight contact with the surface of the circuit breaker base, increasing the friction of the contact surface and fixing the circuit breaker base. At the same time, the pressure plate 531 pushes the support bending plate 525 in the opposite direction, so that the slider 524 slides in the adjusting groove 522, pressing the springback bending plate 52. 3. Deformation, in conjunction with the deformation space of the spring bending plate 523, leaves the buffer adjustment space required for the soft bonding pad 533 to contact, and in conjunction with the elastic force of the compression spring 515 and the sliding of the top pressure rod 512 in the outer sleeve 511, a buffer space is reserved for multi-level protection. Then, the lowering of the knife holder 441 and the lower punching knife 45 are used to punch the edge of the circuit breaker base. Then, the scraping plate 444 is used to scrape the punched edge of the circuit breaker base to remove the burrs. The scraping plate 444 is also used to scrape the punched position to remove the burrs. After the circuit breaker base punching is completed, the cylinder 621 is started. The cylinder 621 drives the push plate 622 to move on the punching seat 61 and push the punched circuit breaker base down. Then, the material conveying mechanism 3 is used to transport and store the finished circuit breaker base.
