Description

Technical Field

[0001] This invention relates to the field of punching equipment technology, and in particular to a punching device for the production of power distribution switch accessories. Background Technology

[0002] In some power distribution switchgear (such as low-voltage switch cabinets, circuit breaker cabinets, distribution boxes, etc.), copper busbars often exist as core internal components. Copper busbar punching is one of the core processing steps in some component suppliers. Busbar processing machines (including punching stations) are key equipment. Common ordinary busbar processing machines are usually equipped with only one set of punching dies at the punching station. In this case, the equipment can only punch one hole per run. If more holes are needed, the copper busbar position needs to be moved manually and the punching operation needs to be performed again.

[0003] When multiple holes need to be punched on a copper busbar and the spacing between the holes is close, the front hole may be easily deformed by the punching and squeezing of the rear hole. When the rear hole is punched, the copper busbar is prone to local stress concentration due to its soft material. The front hole will have problems such as "larger hole diameter", "hole wall concavity" and "hole position displacement" under the extrusion. The punching accuracy of the copper busbar will directly affect the subsequent assembly performance. Therefore, based on the above problems, this invention provides a punching equipment for the production of power distribution switch accessories to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a punching device for the production of power distribution switch accessories. By setting up a support component and a picking component, the support component can not only limit the copper busbar laterally, but also provide rigid support for the front hole after punching, thereby avoiding the problem that the front hole is easily deformed by the pressure of the rear hole. The picking component can not only clamp and limit the placed copper busbar, but also assist in manually moving the position of the copper busbar. The picking component makes the picking process more convenient and efficient, reduces picking resistance, and improves operational safety. Through the above settings, the problem that the front hole is easily deformed by the pressure of the rear hole in the single punching of a conventional busbar processing machine (including punching station) can be solved.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A punching device for producing power distribution switch accessories includes a lower die and a worktable. A support assembly is slidably connected to the top of the worktable to prevent punching deformation. The support assembly is connected to the worktable. A picking assembly is used to assist in picking up copper busbars. The picking assembly is connected to the worktable.

[0007] Optionally, the support assembly includes a horizontal adjustment plate slidably connected to the top of the workbench. The horizontal adjustment plate has evenly distributed punched slots on one side, vertical slots and horizontal slots on the top, and a clearance slot on one side. Oppositely distributed elastic plates are fixedly connected to the inner wall of the vertical slot away from the clearance slot. A connecting rod is snapped into the inside of the elastic plate, and a nut is threaded to the top of the connecting rod. A punch block is slidably connected to one end of the connecting rod.

[0008] Optionally, the punching groove, the vertical groove, the horizontal groove, and the clearance groove are all interconnected, the inner wall dimension of the punching groove is larger than the outer contour dimension of the punch block, and the inner wall dimension of the clearance groove is larger than the outer contour dimension of the connecting rod.

[0009] Optionally, the position of the vertical groove corresponds one-to-one with the position of the punching groove, the vertical groove and the horizontal groove are perpendicular to each other and their inner wall dimensions are the same, and the inner wall dimension of the vertical groove is larger than the top outer contour diameter of the connecting rod.

[0010] Optionally, a slider is fixedly connected to one end of the connecting rod, and a groove is provided on one side of the punch block corresponding to the connecting rod. The inner wall size of the groove is adapted to the outer contour size of the slider.

[0011] Optionally, the top of the lower mold is flush with the top of the worktable, a mold plate is fixedly connected to the center of the lower mold, a hydraulic frame is rotatably connected to the center of the mold plate, and the other end of the hydraulic frame is slidably connected to the worktable. The hydraulic frame has an inverted U-shaped structure.

[0012] Optionally, the picking component includes a longitudinal adjustment plate slidably connected to the top of the workbench. A groove is provided on one side of the longitudinal adjustment plate. A pressure plate is rotatably connected to the inner wall of the groove near the top. A pull rod is slidably connected inside the groove. A pull-out groove is provided on one side of the longitudinal adjustment plate. The inner wall dimension of the pull-out groove is larger than the outer contour dimension of the pull rod.

[0013] Optionally, the longitudinal adjusting plate and the transverse adjusting plate are perpendicular to each other, and a copper busbar is placed between the longitudinal adjusting plate and the transverse adjusting plate. The copper busbar has a through hole, and both sides of the copper busbar contact the transverse adjusting plate and the longitudinal adjusting plate, respectively. The inner wall dimension of the groove is larger than the outer contour dimension of the pull rod.

[0014] Optionally, both ends of the pull rod are bent downwards, with one end bent at an obtuse angle and the other end bent at an acute angle, and the width of one end of the pull rod is greater than the width of the other end of the pull rod.

[0015] Optionally, a retrieval groove is provided on the top of the workbench near the lower mold, and the inner wall of the retrieval groove has a semi-circular cross-section.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a support component and a pick-up component, the support component can not only limit the copper busbar laterally, but also provide rigid support for the front hole after punching, thereby avoiding the problem of the front hole being easily deformed by the punching and squeezing of the rear hole; the pick-up component can not only clamp and limit the placed copper busbar, but also assist in manually moving the position of the copper busbar. The pick-up component makes the pick-up process more convenient and efficient, reduces pick-up resistance, and improves operational safety.

[0018] By setting punching slots, vertical slots, horizontal slots, clearance slots, and nuts and connecting rods, it is not only convenient for the nuts to drive the connecting rods and punch blocks to slide between the vertical slots, horizontal slots, and clearance slots, but also convenient to fix the position of the connecting rod after reaching the required position, ensuring that the punch blocks will not shift. In addition, the nuts protrude from the surface of the horizontal adjustment plate, and the protrusion of the nuts facilitates sliding. The punch blocks that correspond one-to-one with the die punches form rigid support for the holes, avoiding the problem of the front holes being squeezed when the rear holes are punched.

[0019] By using grooves, pull rods, pressure plates, and pull-out slots, the pressure plates can be used to clamp and fix the grooves, thereby further limiting the copper busbars. In addition, the pull-out and retrieval slots make it easy to retrieve the copper busbars, reducing retrieval resistance, saving time and effort, and improving work efficiency and operational safety.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0038] Generally, terms can be understood at least partly from their use in context.

[0039] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0040] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0041] like Figures 1 to 12As shown, an embodiment of the present invention provides a punching device for the production of power distribution switch accessories, including a lower die 2 and a worktable 3. A support component is slidably connected to the top of the worktable 3 to prevent punching deformation. The support component is connected to the worktable 3. The top of the lower die 2 is flush with the top of the worktable 3. A die plate 1 is fixedly connected to the center of the lower die 2. A hydraulic frame 4 is rotatably connected to the center of the die plate 1. The other end of the hydraulic frame 4 is slidably connected to the worktable 3. The hydraulic frame 4 has an inverted U-shaped structure. A picking component is used to assist in picking up the copper busbar 8. The picking component is connected to the worktable 3. The punching device for the production of power distribution switch accessories provided in this application is suitable for common ordinary busbar processing machines (including punching stations) in the case of single-hole operation. In this case, usually only one punching die is equipped at the punching station. The equipment can only punch one hole per operation. If more holes are needed, the position of the copper busbar 8 needs to be manually moved and the punching operation performed again. The working principle of the machine (including the punching station) is disclosed as prior art and will not be elaborated further. In actual products, the single-hole punching of the punching station of a general busbar processing machine is mainly completed by hydraulic drive and mold cooperation. The process is as follows: First, the copper busbar 8 is placed on the worktable 3. The positioning device is used to align the punching position with the punch and the lower mold 2. After the equipment is started, the hydraulic system works. The oil pump generates high-pressure oil to drive the punching cylinder. The piston rod drives the punch downward. Under the pressure, the punch punches the copper busbar 8. Based on the mold mounting position where the shape of the punch and the lower mold 2 correspond, a single hole is punched at the corresponding position of the copper busbar 8. The waste material falls into the collection area under the lower mold 2. After the punching is completed, the punch touches the limit switch and automatically returns, or the return is controlled by the operator. The single-hole punching process ends. The working principle and installation method of the hydraulic drive, positioning device, limit switch and other prior art mentioned in the process are disclosed as prior art. And these structures are not related to the core technical solution of this application, so they will not be elaborated further.

[0042] By setting up support components and pick-up components, the support components can not only limit the lateral movement of the copper busbar 8, but also provide rigid support for the front hole after punching, thereby avoiding the problem of the front hole being easily deformed by the punching and squeezing of the rear hole; the pick-up components can not only clamp and limit the placed copper busbar 8, but also assist in manually moving the position of the copper busbar 8. Compared with directly picking up the copper busbar 8 by hand, this setting makes the pick-up process more convenient and efficient, reduces picking resistance, and improves operational safety.

[0043] As one implementation method in this embodiment, such as Figures 1 to 12As shown, the support assembly includes a horizontal adjustment plate 5 slidably connected to the top of the workbench 3. One side of the horizontal adjustment plate 5 has evenly distributed punched slots 9. The top of the horizontal adjustment plate 5 has vertical slots 10 and horizontal slots 11. One side of the horizontal adjustment plate 5 has a clearance slot 12. Oppositely distributed elastic plates 13 are fixedly connected to the inner wall of the vertical slot 10 away from the clearance slot 12. A connecting rod 16 is snapped into the inside of the elastic plate 13. A nut 15 is threaded onto the top of the connecting rod 16. A punch block 18 is slidably connected to one end of the connecting rod 16. The punched slots 9, vertical slots 10, horizontal slots 11, and clearance slots 12 are also present. All grooves 12 are interconnected. The inner wall dimension of the punching groove 9 is larger than the outer contour dimension of the punch block 18. The inner wall dimension of the clearance groove 12 is larger than the outer contour dimension of the connecting rod 16. The position of the vertical groove 10 corresponds one-to-one with the position of the punching groove 9. The vertical groove 10 and the horizontal groove 11 are perpendicular to each other and their inner wall dimensions are the same. The inner wall dimension of the vertical groove 10 is larger than the top outer contour diameter of the connecting rod 16. A slider 17 is fixedly connected to one end of the connecting rod 16. A sliding groove 19 is opened on one side of the punch block 18 corresponding to the connecting rod 16. The inner wall dimension of the sliding groove 19 is adapted to the outer contour dimension of the slider 17.

[0044] Specifically, the center of mold plate 1 corresponds to that of lower mold 2. Lower mold 2 is adapted to the outer contour structure of worktable 3, making the top of lower mold 2 flush with the top of worktable 3. Mold plate 1 is a turntable structure with six mold mounting positions. Lower mold 2 is fixed to the corresponding positions on mold plate 1 by bolts. Lower mold 2 is a circular structure with mounting positions corresponding to the six mold hole diameters on mold plate 1. Rotating mold plate 1 can drive lower mold 2 to rotate synchronously, so that the mold hole diameters on mold plate 1 and lower mold 2 always maintain a corresponding state (e.g., ...). Figures 1 to 4 As shown), the punching slot 9 on the horizontal adjusting plate 5 has an inner wall dimension larger than the outer contour dimension of the largest punch among the six dies. The number of punching slots 9 and vertical slots 10 is also six (as shown). Figures 5 to 7 As shown), each elastic piece 13 has a nut 15 and a connecting rod 16 inside. One end of each of the six connecting rods 16 is slidably connected to a punch block 18 that corresponds one-to-one with the outer contour dimensions of the punches of the six molds on the mold plate 1. The height of each punch block 18 is smaller than the inner wall height of the punching groove 9, so that each punch block 18 can slide smoothly in the punching groove 9 (as shown). Figure 8As shown), the punch block 18 is designed to slide up and down, which facilitates its placement in the hole 14. Since the copper busbar 8 has a certain thickness, when placing the punch block 18 in the hole 14, hold the punch block 18 and lift it upwards until it is higher than the thickness of the copper busbar 8, then slide it to a position convenient for placing the punch block 18. This allows the punch block 18 to support the hole 14, preventing pressure on the front hole during subsequent punching. The connecting rod 16 has an L-shaped structure. The diameter of the upper part of the connecting rod 16 is smaller than the diameter of the lower part. The top of the upper part of the connecting rod 16 is threaded to the nut 15 (e.g., ...). Figure 8 As shown), the upper part of the connecting rod 16 has a diameter smaller than the inner wall dimensions of the vertical groove 10 and the horizontal groove 11, while the outer diameter of the nut 15 is larger than the inner wall dimensions of the vertical groove 10 and the horizontal groove 11. When the nut 15 is loosely connected to the horizontal adjusting plate 5, it facilitates the sliding of the connecting rod 16 and the punch block 18 between the vertical groove 10, the horizontal groove 11, and the clearance groove 12. When the nut 15 is tightly connected to the horizontal adjusting plate 5, it facilitates the fixing of the position of the connecting rod 16, ensuring that the punch block 18 does not shift. Furthermore, the nut 15 protrudes from the surface of the horizontal adjusting plate 5, allowing for easy sliding when the connection between the nut 15 and the horizontal adjusting plate 5 is loose. The horizontal adjusting plate 5 can slide on the worktable 3 and be easily fixed (e.g., Figures 5 to 6 As shown in the figure, the horizontal adjustment plate 5 slides and is fixed on the worktable 3 to adapt to the size of the copper busbar 8 and the position of the punching. The specific structure and working principle of the horizontal adjustment plate 5 sliding on the worktable 3 are disclosed as prior art, so they will not be described in detail.

[0045] By setting punching slot 9, vertical slot 10, horizontal slot 11, clearance slot 12, nut 15, and connecting rod 16, it is not only convenient for nut 15 to drive connecting rod 16 and punch block 18 to slide between vertical slot 10, horizontal slot 11, and clearance slot 12, but also convenient to fix the position of connecting rod 16 after reaching the required position, ensuring that punch block 18 will not shift. In addition, nut 15 protrudes from the surface of horizontal adjustment plate 5, and the protrusion of nut 15 facilitates sliding. Punch blocks 18, which correspond one-to-one with the die punch, form rigid support for hole 14, avoiding the problem of squeezing front hole when punching rear hole.

[0046] As one implementation method in this embodiment, such as Figures 1 to 12As shown, the picking component includes a longitudinal adjustment plate 6 slidably connected to the top of the workbench 3. A groove 20 is formed on one side of the longitudinal adjustment plate 6. A pressure plate 22 is rotatably connected to the inner wall of the groove 20 near the top. A pull rod 21 is slidably connected inside the groove 20. Evenly distributed pull-out grooves 23 are formed on one side of the longitudinal adjustment plate 6. The inner wall dimension of the pull-out groove 23 is larger than the outer contour dimension of the pull rod 21. The longitudinal adjustment plate 6 and the transverse adjustment plate 5 are perpendicular to each other. A copper busbar 8 is placed between the worktable 3 and a hole 14 is opened through the copper busbar 8. The two sides of the copper busbar 8 contact the horizontal adjustment plate 5 and the vertical adjustment plate 6 respectively. The inner wall dimension of the groove 20 is larger than the outer contour dimension of the pull rod 21. Both ends of the pull rod 21 are bent downward, one end is bent at an obtuse angle and the other end is bent at an acute angle. The width dimension of one end of the pull rod 21 is larger than the width dimension of the other end of the pull rod 21. A pick-up groove 7 is opened at the top of the worktable 3 near the lower mold 2. The inner wall cross-section of the pick-up groove 7 is a semi-circular structure.

[0047] Furthermore, a horizontal adjustment plate 5 and a vertical adjustment plate 6 are slidably mounted on the top of the workbench 3 (e.g., Figures 1 to 4 As shown), this allows for lateral and longitudinal positional limiting of the copper busbar 8. The lateral adjustment plate 5 and longitudinal adjustment plate 6 are adjusted by manual sliding and bolt fastening. The lateral adjustment plate 5 slides laterally along the worktable 3, and the longitudinal adjustment plate 6 slides longitudinally. The adjustment and fixing methods are disclosed in the prior art and will not be elaborated further. A groove 20 is formed on the side of the longitudinal adjustment plate 6 closest to the copper busbar 8. The opening size of the groove 20 is larger than the outer contour size of the pull rod 21. The inner wall contour of the bottom of the groove 20 is adapted to the outer contour of one end of the pull rod 21 (e.g., ...). Figures 9 to 10 As shown), this allows the pull rod 21 to be inserted into the groove 20. A pressure plate 22 is rotatably connected to the groove 20 near its top. The length of the pressure plate 22 matches the inner wall dimensions of the groove 20. The free end of the pressure plate 22 rotates along the center of the pivot at the fixed end of the pressure plate 22. Under the weight of the pressure plate 22, the free end of the pressure plate 22 presses against one end of the pull rod 21 (as shown). Figure 9 As shown), the pull rod 21 is also limited by the pressure of the pressure plate 22. When the external force on the pull rod 21 is greater than the weight of the pressure plate 22 or the static friction between the pressure plate 22 and the groove 20, the free end of the pressure plate 22 can rotate upward (as shown). Figure 10(As shown) or the pull rod 21 moves along the long axis of the groove 20. Since the width of one end of the pull rod 21 is greater than the width of the other end, manually moving the pull rod 21 will bring one side of the other end of the pull rod 21 into contact with the copper busbar 8, thus clamping and fixing the copper busbar 8. In addition, when the copper busbar 8 needs to be removed after one punching, the finger can hook the acute angle of the other end of the pull rod 21 to easily pull the pull rod 21 out of the groove 20 to the top of the pullout groove 23. One end of the pull rod 21 moves down along the pullout groove 23 until it contacts the side of the copper busbar 8 (e.g. Figure 3 As shown), this facilitates the removal of the copper busbar 8, which is tightly attached between the horizontal adjustment plate 5 and the vertical adjustment plate 6, and pulls the copper busbar 8 above the retrieval slot 7 (as shown). Figure 4 and Figure 12 As shown in the figure, the picking groove 7 is used to reduce the picking resistance. The surface of the copper busbar 8 is tightly attached and has high friction. After the groove is opened, the fingers can be inserted to exert force. There is no need to pry or pull. It can be picked up easily.

[0048] By setting the groove 20, pull rod 21, pressure plate 22 and pull-out groove 23 together, the pressure plate 22 can be used to clamp and fix the groove 20 by its own weight, thereby further limiting the copper busbar 8. In addition, the pull-out groove 23 and the pick-up groove 7 are opened to make it easy to pick up the copper busbar 8, reduce the picking resistance, save time and effort, and improve work efficiency and operation safety.

[0049] The working principle of the technical solution provided by this invention is as follows:

[0050] In use, first rotate the mold mounting position to be punched to below the hydraulic frame 4, so that the hydraulic frame 4 can move downward under hydraulic drive, thereby realizing the punching of the copper busbar 8. Then, adjust the positional relationship of the horizontal adjustment plate 5 and the vertical adjustment plate 6 according to the size of the copper busbar 8, so that the position of the copper busbar 8 to be punched is precisely aligned with the center of the mold mounting position to be punched on the mold plate 1 and the lower mold 2, ensuring that the punch and the lower mold 2 are aligned. Through the dual positioning of horizontal and vertical, and under the action of the weight of the pressure plate 22, the free end of the pressure plate 22 presses against one end of the pull rod 21. At the same time, the pull rod 21 is limited by the squeezing of the pressure plate 22, and the other end of the pull rod 21 contacts the copper busbar 8, which can clamp and fix the copper busbar 8. Multiple limiting realizes the punching of the copper busbar 8. Precise control of the hole position avoids errors from manual scribing, improving processing efficiency and accuracy. The lower die 2 and the punch on the mold plate 1 work together to complete the shearing and punching. Scrap material falls into the collection area through the center hole of the mounting position of the lower die 2. If more holes are needed, the position of the copper busbar 8 needs to be manually moved for another punching operation. During the second punching, to avoid the problem of the front hole being easily deformed by the punching and squeezing of the rear hole, when the copper busbar 8 needs to be removed after one punching, the finger hooks the acute angle of the other end of the pull rod 21 to easily pull the pull rod 21 out of the groove 20 to the top of the pullout groove 23. One end of the pull rod 21 goes down along the pullout groove 23 until it contacts the side of the copper busbar 8. This state of the pull rod 21 going down along the pullout groove 23 until it contacts the side of the copper busbar 8 is the second state of the equipment described above. The copper busbar 8, which is tightly attached between the horizontal adjustment plate 5 and the vertical adjustment plate 6, is then removed and pulled up to the top of the picking slot 7. This pulling up of the copper busbar 8 to the top of the picking slot 7 using the pull rod 21 represents the third state of the equipment described above. The picking slot 7 is used to reduce picking resistance. The surface of the copper busbar 8 is tightly fitted with high friction, allowing fingers to be inserted and applied force after slotting. It can be easily picked up without straining. After placing and positioning the copper busbar 8 according to the required punching position, and given the thickness of the copper busbar 8, the punch block 18 is raised upwards above the thickness of the copper busbar 8. Then, the connecting rod 16 and the punch block 18 slide between the vertical slot 10, the horizontal slot 11, and the clearance slot 12 until the first hole 14 is reached. The punch block 18 is then placed in the first hole. Inside the hole 14, which has been drilled once, the nut 15 is tightened with a tool to ensure that the punch block 18 does not shift. This allows the punch block 18 to provide stable support for the hole 14, preventing the front hole from being squeezed during subsequent punching. The state where the punch block 18 is placed inside the hole 14 after the first drilling and one side of the other end of the pull rod 21 is in contact with the side of the copper busbar 8 is the first state of this equipment described above. Then, the punching process is carried out again. After punching, the operation of easily removing the copper busbar 8 is repeated. This equipment can not only limit the copper busbar 8 laterally, but also provide rigid support for the front hole after punching, thereby preventing the front hole from being deformed by the pressure of subsequent punching. It can also clamp and limit the placed copper busbar 8.Furthermore, it can assist in manually moving the position of copper busbar 8. Compared to directly handling copper busbar 8 by hand, this design makes the component handling process more convenient and efficient, reduces handling resistance, and improves operational safety.
