Description

Technical Field

[0001] The present invention belongs to the technical field of copper block processing, and particularly relates to a copper block punching device and a punching method for a high-voltage switch box that are convenient to use. Background Art

[0002] The copper block on the high-voltage switch box usually refers to a copper bar or a copper busbar. During the installation process of the high-voltage switch box, copper blocks are often required to connect wires and are key components for conducting electricity, connecting, or contacting. When manufacturing copper blocks, processes such as shearing, punching, and bending are required. Currently, when punching holes in copper blocks, in order to facilitate the discharge of waste materials after punching, the diameter of the punching hole is generally set to be larger than the diameter of the hole on the copper block. When punching, the punching head acts on the copper block to form a hole with the required shape. However, when the punching head penetrates the copper block, since the diameter of the punching hole is larger than the diameter of the hole, the bottom edge area of the hole will bulge downward, resulting in the bottom edge area of the hole being relatively sharp, which is likely to scratch the staff during the production process and easily damage the connecting components during actual installation.

[0003] In response to the above technical problems, the applicant has retrieved some prior arts to avoid the downward bulge of the bottom of the hole after punching, resulting in this area being relatively sharp. For example, a deformation-preventing punching device and punching process for thin-walled metal plates with the patent publication number CN118543739B. Its main technical means is that when punching, the output end of the hydraulic cylinder drives the punching component to move downward, and at the same time drives the auxiliary extrusion component to limit and fix the plate. While the auxiliary extrusion component extrudes and fixes the plate, the punching component punches the plate. At this time, the punched hole is the first hole (the size of the first hole is slightly smaller than the punching hole). When the punching component finishes punching, the second auxiliary component works, making the edge of the hole to be polished exposed. At this time, the first auxiliary component will cooperate with the polishing component to polish the metal plate in the opposite direction until a second hole with the same size as the punching hole is formed. After analysis by the applicant, the disadvantages of this technical solution are as follows: The above solution first punches a first hole with a diameter smaller than the preset hole on the plate, and then polishes the inner wall of the first hole to form a second hole, and the size of the second hole is consistent with the size of the preset hole. Such an operation will increase the punching process, thereby reducing the punching efficiency, and it is very difficult to control the size of the polished second hole to be consistent with the size of the preset hole, thus reducing the punching quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a copper block punching device and a punching method for a high-voltage switch box that are convenient to use in view of the deficiencies of the prior art, so as to solve the technical problem that the prior art increases the punching process and reduces the punching efficiency by using the method of punching first and then polishing to avoid the downward bulge of the bottom of the hole after punching.

[0005] The object of the present invention can be achieved by the following technical solutions: A copper block punching device on a high-voltage switch box that is convenient to use, comprising a punching machine, a punching head, an operating table, a punching hole and a fixture. The device further comprises: Support blocks. An annular sliding groove is formed on the inner wall of the punching hole. Two groups of support blocks are symmetrically and slidably installed in the sliding groove. The top of the support blocks is flush with the top of the operating table. The inner side of the support blocks is arc-shaped, and the arc surface on the inner side of the support blocks is located outside the holes to be punched on the copper block. Toothed ring. A toothed ring is rotatably installed in the operating table. The inner wall of the toothed ring is located inside the punching hole. Connecting plates are symmetrically arranged inside the toothed ring. The connecting plates are fixed to the bottom of the support blocks. A driving member is installed in the operating table. The output end of the driving member is installed with a gear, and the gear meshes with the toothed ring.

[0006] As a preference of the above technical solution, the support block comprises a slider and a movable block. The slider is slidably installed in the sliding groove. The slider is telescopically connected to the movable block. A fixing plate is arranged at the bottom of the slider. The fixing plate is fixedly connected to the connecting plate. A support plate is arranged at the bottom of the movable block. An arc-shaped plate inclined obliquely upward is fixed to the bottom of the fixing plate. The arc-shaped plate is located at the front end of the rotating direction of the support block. A plurality of telescopic impact rods are annularly and arrayedly installed on the inner wall of the punching hole. The highest point of the arc-shaped plate is higher than the highest point of the impact rods.

[0007] As a preference of the above technical solution, an installation groove is formed on the side surface of the movable block, and a horizontal scraping blade is elastically installed in the installation groove.

[0008] As a preference of the above technical solution, a vertical scraping blade is arranged at the top of the horizontal scraping blade, and the vertical scraping blade is close to the arc surface of the support block.

[0009] As a preference of the above technical solution, a telescopic groove is formed on the surface of the connecting plate. A movable rod is vertically movably installed in the telescopic groove. An elastic member is connected between the bottom of the movable rod and the bottom of the telescopic groove. A guiding groove is formed in the movable block. An inclined surface is arranged at the top of the movable rod. An inclined portion is arranged on one side of the guiding groove close to the inclined surface. A rotating seat is arranged on the side of the movable rod away from the connecting plate. A turntable is installed between the two rotating seats. The turntable is located at the center of the punching hole.

[0010] As a preference of the above technical solution, the turntable is elastically and rotatably installed between the two rotating seats.

[0011] As an optimization of the above technical solution, an extrusion plate is elastically and rotatably installed on one side of the connecting plate. The extrusion plate always has a tendency to rotate towards the inner wall of the punching hole. The extrusion plate is located at the rear end of the rotating direction of the support block. An extrusion block is arranged on the side of the extrusion plate facing the center of the punching hole.

[0012] A punching method for a copper block punching device on an easy-to-use high-voltage switch cabinet. The method is applied to the above-mentioned copper block punching device on an easy-to-use high-voltage switch cabinet. The method includes the following steps: Step S1: First, fix the copper block with a fixture, then start the punching machine to lower the punching head, and at the same time start the driving part to make the gear drive the toothed ring to rotate, and the toothed ring drives the two support blocks to rotate around the center of the punching hole; Step S2: When the punching head punches the copper block downward, the two support blocks support the bottom edge area of the hole during rotation, avoiding the bottom edge area of the hole from protruding downward; Step S3: While the two support blocks are rotating, the arc-shaped plate first compresses the impact rod at the front end of the support block. When the support block moves below the impact rod, the impact rod elastically elongates and impacts the support block, and the support block transmits the impact force to the bottom edge area of the hole, further avoiding the bottom edge area of the bottom hole from protruding downward; Step S4: After the punching head punches downward, a hole is formed in the copper block and waste is generated. The waste falls onto the turntable. At the same time, the punching head moves upward away from the punching hole. Due to the downward impact of the waste, the turntable moves downward. The inclined surface is squeezed by the movable rod to move the movable block away from the slider until the vertical scraping blade moves to the inside of the hole and abuts against the inner wall of the hole. At the same time, the horizontal scraping blade abuts against the bottom edge area of the hole. The support block rotates to drive the horizontal scraping blade and the vertical scraping blade to remove the burrs on the bottom edge area of the hole.

[0013] Step S5: The waste is discharged downward through the rotation of the turntable to complete the punching operation. Repeat the above steps for punching.

[0014] The beneficial effects of the present invention are as follows: 1. In the present invention, when the punching head moves downward to punch the copper block, the two support blocks support the bottom edge area of the hole, and the two support blocks rotate, so that the two support blocks can support the bottom edge area of the hole in all directions. Since the copper block material is relatively soft, when the copper block is stressed, it effectively avoids the bottom edge area of the hole from protruding downward. In this way, when punching, it can avoid the bottom edge area of the hole from protruding downward. Compared with the prior art, this saves the grinding step, enables the hole to be formed quickly, thereby improving the punching efficiency, and the size of the punched hole is consistent with the preset hole, thus ensuring the punching quality and making the copper block meet the preset punching requirements after punching; 2. In the present invention, since the support block contacts the bottom of the copper block, during the rotation of the two groups of support blocks, friction is generated between the support block and the copper block, causing the bottom edge area of the hole in the copper block to be deformed by heat. On the one hand, under the support and extrusion of the support block, it can further effectively prevent the bottom edge area of the hole from protruding downward. On the other hand, when the copper block is deformed by heat, the texture of the copper block becomes softer, so that the punching head can quickly complete the punching of the copper block, and the waste can be quickly discharged, thereby further improving the punching efficiency; 3. In the present invention, during the movement of the slider along the chute, the fixed plate at the bottom of the slider drives the arc plate to rotate around the inner wall of the punching hole. The arc plate is located at the front end of the support block when rotating, so that the arc plate can first slowly squeeze the impact rod to compress the impact rod. When the impact rod moves to the end of the arc plate, since the arc plate no longer restricts the impact rod and cooperates with the elastic rebound of the impact rod, the impact rod elastically elongates to impact the support plate and the movable block. After being impacted, the movable block transmits part of the impact force to the copper block, so that the bottom edge area of the hole in the copper block is impacted. With the rotational support and extrusion of the movable block, it can further effectively prevent the bottom edge area of the hole from protruding downward. Compared with the prior art, this saves the grinding step, enables the hole to be quickly formed, and thus improves the punching efficiency; 4. In the present invention, when the punching is completed, the generated waste will fall downward and fall onto the turntable. At this time, the punching head moves upward away from the punching hole. Due to the downward impact of the waste, the turntable moves downward. The downward movement of the turntable drives the rotating seat and the movable rod to move downward. The downward movement of the movable rod causes the inclined surface to squeeze the inclined part, so that the movable block moves away from the slider until the vertical scraper moves to the inside of the hole and abuts against the inner wall of the hole. At the same time, the horizontal scraper abuts against the bottom edge area of the hole. The rotation of the support block drives the horizontal scraper and the vertical scraper to remove the burrs in the bottom edge area of the hole, thereby effectively preventing these burrs from hurting the workers during the subsequent processing of the copper block, and also improving the quality of the hole in the copper block.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0018] As Figures 1-5 shown, a copper block punching device on a high-voltage switch box that is convenient to use includes a punching machine 1, a punching head 2, an operating table 3, a punching hole 4, and a fixture 15. The device further includes: Support blocks 5. An annular slide groove 41 is opened on the inner wall of the punching hole 4. Two groups of support blocks 5 are symmetrically and slidably installed in the slide groove 41. The top of the support blocks 5 is flush with the top of the operating table 3. The inner side of the support blocks 5 is arc-shaped, and the arc surface on the inner side of the support blocks 5 is located outside the hole to be punched in the copper block. Tooth ring 6. A tooth ring 6 is rotatably installed in the operating table 3. The inner wall of the tooth ring 6 is located in the punching hole 4. Two connecting plates 8 are symmetrically arranged inside the tooth ring 6. The connecting plates 8 are fixed to the bottom of the support blocks 5. A driving part 71 is installed in the operating table 3, and a gear 7 is installed at the output end of the driving part 71. The gear 7 meshes with the tooth ring 6.

[0019] In actual application of this embodiment, when the punching head 2 moves downward to punch the copper block, the two support blocks 5 support the bottom edge area of the hole, and the two support blocks 5 rotate, so that the two support blocks 5 can support the bottom edge area of the hole in all directions. Since the copper block material is relatively soft, when the copper block is stressed, it effectively avoids the bottom edge area of the hole from protruding downward. In this way, when punching the hole, it can be avoided that the bottom edge area of the hole protrudes downward. Compared with the prior art, this saves the grinding step, enables the hole to be formed quickly, thereby improving the punching efficiency, and the size of the punched hole is consistent with the preset hole, thus ensuring the punching quality and making the copper block meet the preset punching requirements after punching. The size of the circle formed between the two groups of support blocks 5 is the same as the size of the hole to be punched in the copper block, which can ensure that the size of the punched hole is consistent with the preset hole size, thus ensuring the punching quality; Since only two groups of support blocks 5 are provided, it is not easy to affect the downward movement of the punching head 2 to punch the copper block. Moreover, since there is a large space between the two groups of support blocks 5, the generated waste is not easy to get stuck in the punching hole 4; Since the support block 5 contacts the bottom of the copper block, during the rotation of the two groups of support blocks 5, friction is generated between the support block 5 and the copper block, resulting in the heat deformation of the bottom edge area of the hole in the copper block. On the one hand, under the support and extrusion of the support block 5, it can further effectively prevent the bottom edge area of the hole from protruding downward. On the other hand, when the copper block is heated and deformed, the texture of the copper block becomes softer, so that the punching head 2 can quickly complete punching when punching the copper block, and the waste can be quickly discharged, thereby further improving the punching efficiency.

[0020] Further, the support block 5 includes a slider 51 and a movable block 52. The slider 51 is slidably installed in the chute 41. The slider 51 is telescopically connected to the movable block 52. A fixing plate 511 is provided at the bottom of the slider 51. The fixing plate 511 is fixedly connected to the connecting plate 8. A support plate 521 is provided at the bottom of the movable block 52. An arc plate 10 inclined obliquely upward is fixed at the bottom of the fixing plate 511. The arc plate 10 is located at the front end of the rotation direction of the support block 5. A plurality of telescopic impact rods 11 are annularly arranged on the inner wall of the punching hole 4. The highest point of the arc plate 10 is higher than the highest point of the impact rod 11.

[0021] In one case of this embodiment, the impact rod 11 can be an elastic telescopic rod or other components that can elastically expand and contract and generate an impact force.

[0022] In the actual application of this embodiment, during the movement of the slider 51 along the chute 41, the fixing plate 511 at the bottom of the slider 51 drives the arc plate 10 to rotate around the inner wall of the punching hole 4. The arc plate 10 is located at the front end of the support block 5 during rotation, so that the arc plate 10 can first slowly squeeze the impact rod 11 to compress the impact rod 11. When the impact rod 11 moves to the end of the arc plate 10, since the arc plate 10 no longer restricts the impact rod 11 and in cooperation with the rebound of the impact rod 11, the impact rod 11 elastically elongates to impact the support plate 521 and the movable block 52. After being impacted, the movable block 52 transmits part of the impact force to the copper block, so that the bottom edge area of the hole in the copper block is impacted. With the rotational support and extrusion of the movable block 52, it can further effectively prevent the bottom edge area of the hole from protruding downward. Compared with the prior art, this saves the grinding step and enables the hole to be quickly formed, thus improving the punching efficiency; After the movable block 52 transfers part of the impact force to the copper block, the copper block will generate a short vibration. In this way, when the stamping head 2 punches the copper block, the waste material can be quickly formed and fall off, thereby further improving the punching efficiency.

[0023] As Figures 5-7 shown, an installation groove 522 is formed on the side surface of the movable block 52, and a horizontal scraping blade 9 is elastically installed in the installation groove 522.

[0024] Furthermore, a vertical scraping blade 91 is arranged at the top of the horizontal scraping blade 9, and the vertical scraping blade 91 is close to the arc surface of the support block 5.

[0025] Furthermore, a telescopic groove 81 is formed on the surface of the connecting plate 8, a movable rod 12 is installed up and down in the telescopic groove 81, an elastic member 82 is connected between the bottom of the movable rod 12 and the bottom of the telescopic groove 81, a guiding groove 523 is formed in the movable block 52, an inclined surface 122 is arranged at the top of the movable rod 12, an inclined portion 524 is arranged on one side of the guiding groove 523 close to the inclined surface 122, a rotating seat 121 is arranged on the side of the movable rod 12 away from the connecting plate 8, and a turntable 13 is installed between the two rotating seats 121. The turntable 13 is located at the center of the punching hole 4.

[0026] It should be noted that when punching the copper block, burr areas often form below the fracture zone of the hole at the bottom of the copper block, and the burrs often protrude from the bottom of the edge of the hole in the copper block. These burrs are likely to hurt workers during the subsequent processing of the copper block; in response to the above problems, a corresponding structure is proposed to solve this problem.

[0027] In one case of this embodiment, a spring is arranged at the telescopic connection between the slider 51 and the movable block 52, so that the movable block 52 always has a tendency to move towards the slider 51.

[0028] In practical application of this embodiment, when the stamping and punching are completed, the generated waste will fall downward and land on the turntable 13. At this time, the stamping head 2 moves upward away from the stamping hole 4. Due to the downward impact of the waste, the turntable 13 moves downward. The downward movement of the turntable 13 drives the rotating seat 121 and the movable rod 12 to move downward. The downward movement of the movable rod 12 causes the inclined surface 122 to move along the inclined portion 524 on the guide groove 523. Since the inclined surface 122 and the inclined portion 524 are inclined and fit with each other, the downward movement of the movable rod 12 causes the inclined surface 122 to press against the inclined portion 524, causing the movable block 52 to move in the direction away from the slider 51. When the vertical scraper 91 moves past the hole in the copper block, since the horizontal scraper 9 is elastically installed in the installation groove 522, the horizontal scraper 9 drives the vertical scraper 91 to move upward, causing the horizontal scraper 9 to abut against the bottom edge area of the hole. Since the movable block 52 always has a tendency to move in the direction of the slider 51, although the movable block 52 moves in the direction away from the slider 51, the movable block 52 will slowly move in the direction of the slider 51 after being affected by the movable rod 12, and the vertical scraper 91 will slowly abut against the inner wall of the hole. In this way, after the support block 5 rotates, it drives the horizontal scraper 9 and the vertical scraper 91 to remove the burrs at the bottom edge area of the hole, effectively preventing these burrs from hurting the workers during the subsequent processing of the copper block, and at the same time improving the quality of the hole in the copper block.

[0029] As Figures 2-4 shown, the turntable 13 is elastically and rotatably installed between the two sets of rotating seats 121.

[0030] In one case of this embodiment, a torsion spring is provided at the elastic rotation part between the turntable 13 and the rotating seat 121, so that the turntable 13 is in a horizontal state under normal circumstances and will slowly return to the horizontal state after rotation.

[0031] In practical application of this embodiment, when the waste falls and impacts the turntable 13, the turntable 13 drives structures such as the movable rod 12 to move downward, causing the horizontal scraper 9 and the vertical scraper 91 to remove the burrs at the bottom edge area of the hole. After that, due to the uneven gravity distribution of the waste on the turntable 13, the turntable 13 will flip to one side, facilitating the discharge of the waste.

[0032] As Figure 4 and Figure 5 shown, one side of the connecting plate 8 is elastically and rotatably installed with a pressing plate 14. The pressing plate 14 always has a tendency to rotate towards the inner wall of the stamping hole 4. The pressing plate 14 is located at the rear end of the rotating direction of the support block 5. A pressing block 141 is provided on the side of the pressing plate 14 facing the center of the stamping hole 4.

[0033] It should be noted that since the copper block is relatively soft in texture and has a certain adhesiveness, when the punching head 2 punches the copper block, the generated waste is easily adhered to the bottom of the punching head 2, which will cause the waste to not be discharged normally and the waste cannot fall onto the turntable 13, resulting in the horizontal scraping blade 9 and the vertical scraping blade 91 being unable to remove burrs; in response to the above problems, a corresponding structure is proposed to solve this problem.

[0034] In a case of this embodiment, a torsion spring is provided at the elastic rotating part of the pressing plate 14 and the connecting plate 8, so that the pressing plate 14 always has a tendency to rotate towards the inner wall of the punching hole 4.

[0035] In the actual application of this embodiment, during the process of the connecting plate 8 driving the support block 5 to rotate, the connecting plate 8 also drives the pressing plate 14 to move along the inner wall of the punching hole 4. When the pressing plate 14 moves to the impact rod 11, since the impact rod 11 protrudes from the inner wall of the punching hole 4, the pressing plate 14 will slowly tilt up and move towards the center position of the punching hole 4. Cooperating with the pressing block 141, after the punching head 2 brings the waste into the punching hole 4, the pressing block 141 will slowly approach the waste and squeeze the waste, so that the waste can fall off the punching head 2, effectively avoiding the waste from adhering to the bottom of the punching head 2, avoiding the waste from not being discharged normally, and avoiding the waste from not being able to fall onto the turntable 13; The pressing plate 14 can elastically move up and down on the connecting plate 8. In this way, when the waste moves down and the pressing block 141 has moved towards the center position of the punching hole 4, at this time, the pressing block 141 is located below the waste, and the pressing block 141 cannot squeeze the waste down. When the pressing block 141 moves between two adjacent impact rods 11, at this time, the pressing plate 14 rebounds, so that the pressing block 141 moves away from the center of the punching hole 4. In this way, the pressing block 141 is located outside the waste. At this time, the pressing plate 14 will drive the pressing block 141 to move up, so that the pressing block 141 and the waste are on the same horizontal plane. When the pressing plate 14 tilts up again and moves towards the center position of the punching hole 4, the pressing block 141 will squeeze the waste down.

[0036] A punching method for a copper block punching device on an easy-to-use high-voltage switch cabinet, the method is applied to the above-mentioned easy-to-use copper block punching device on a high-voltage switch cabinet, and the method includes the following steps: Step S1: First, fix the copper block through the fixture 15, then start the punching machine 1 to move the punching head 2 downward, and at the same time start the driving part 71 to make the gear 7 drive the toothed ring 6 to rotate, and the toothed ring 6 drives the two groups of support blocks 5 to rotate around the center of the punching hole 4; Step S2: When the punching head 2 punches the copper block downward, the two groups of support blocks 5 support the bottom edge area of the hole during rotation, avoiding the bottom edge area of the hole from protruding downward; Step S3: While the two sets of support blocks 5 are rotating, the arc-shaped plate 10 first compresses the impact rod 11 at the front end of the support block 5. When the support block 5 moves below the impact rod 11, the impact rod 11 elastically elongates and impacts the support block 5, and the support block 5 then transmits the impact force to the bottom edge area of the hole, further preventing the bottom edge area of the bottom hole from protruding downward; Step S4: After the punch head 2 punches downward, a hole is formed in the copper block and waste is generated. The waste falls onto the turntable 13. At the same time, the punch head 2 moves upward away from the punching hole 4. Due to the downward impact of the waste, the turntable 13 moves downward. The inclined surface 122 is pressed against the inclined portion 524 by moving the movable rod 12 downward, causing the movable block 52 to move away from the slider 51 until the vertical scraping blade 91 moves to the inside of the hole and abuts against the inner wall of the hole. At the same time, the horizontal scraping blade 9 abuts against the bottom edge area of the hole. The support block 5 rotates to drive the horizontal scraping blade 9 and the vertical scraping blade 91 to remove the burrs from the bottom edge area of the hole.

[0037] Step S5: The waste is discharged downward through the rotation of the turntable 13 to complete the punching operation, and the above steps are repeated for punching.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.

8. A punching method for a copper block punching device on an easy-to-use high-voltage switch cabinet, the method being applied to the easy-to-use copper block punching device on a high-voltage switch cabinet as described in any one of the above claims 1-7. The method includes the following steps: Step S1: First, fix the copper block through the fixture (15), then start the punching machine (1) to lower the punching head (2), and at the same time start the driving member (71) to make the gear (7) drive the toothed ring (6) to rotate, and the toothed ring (6) drives the two support blocks (5) to rotate around the center of the punching hole (4); Step S2: When the punching head (2) punches the copper block downward, the two support blocks (5) support the bottom edge area of the hole during rotation, avoiding the bottom edge area of the hole from protruding downward; Step S3: While the two support blocks (5) are rotating, the arc-shaped plate (10) first compresses the impact rod (11) at the front end of the support block (5). When the support block (5) moves below the impact rod (11), the impact rod (11) elastically elongates and impacts the support block (5), and the support block (5) transmits the impact force to the bottom edge area of the hole, further avoiding the bottom edge area of the bottom hole from protruding downward; Step S4: After the punching head (2) punches downward, a hole is formed in the copper block and waste is generated. The waste falls onto the turntable (13). At the same time, the punching head (2) moves upward away from the punching hole (4). Due to the downward impact of the waste, the turntable (13) moves downward. The inclined surface (122) squeezes the inclined part (524) through the downward movement of the movable rod (12), so that the movable block (52) moves away from the slider (51) until the vertical scraping blade (91) moves to the inside of the hole and abuts against the inner wall of the hole. At the same time, the horizontal scraping blade (9) abuts against the bottom edge area of the hole. The rotation of the support block (5) drives the horizontal scraping blade (9) and the vertical scraping blade (91) to remove the burrs at the bottom edge area of the hole; Step S5: The waste is discharged downward through the rotation of the turntable (13) to complete the punching operation. Repeat the above steps for punching.
