Description

Technical Field

[0001] The present application relates to the technical field of copper busbar punching and shearing integrated device, and in particular to a copper busbar punching and shearing integrated device for a distribution box. Background Art

[0002] A distribution box is an electrical device installed in a building or industrial use, used to carry power cables, wires and other electrical components, as well as to protect personnel and equipment from dangers such as electric shock and fire. In the installation and use of distribution boxes, copper busbars are often needed to connect the wires. Copper busbars are long strips of copper, usually used for circuit boards and conductive parts. Copper busbars have good electrical and thermal conductivity, as well as good corrosion resistance and plasticity. Due to its excellent performance, copper busbars are widely used in electrical, electronic, and communication fields, and have become one of the indispensable materials in modern industry. Copper busbars connect various devices tightly together through bolts or other connection methods to form a complete electrical circuit.

[0003] For distribution boxes of different sizes and different uses, the copper busbar needs to be sheared to adapt to distribution boxes of different sizes. At the same time, the copper busbar needs to be punched and tapped for subsequent fixing by bolts. Since both shearing and cutting require a large impact force on the copper busbar, it is easy to cause the processing position of the copper busbar to shift and deform the copper busbar, and the position accuracy of the copper busbar punching is required to be high. Therefore, the copper busbar is usually processed by shearing first and then punching. When the processing is divided into two steps, the copper busbar needs to be precisely clamped on the shearing equipment. After shearing, the copper busbar needs to be removed and precisely clamped again on the punching equipment. The copper busbar after shearing will generate high temperature, which is not convenient for use and needs to be cooled, resulting in low efficiency of shearing and punching of the copper busbar, so it needs to be improved. Summary of the invention

[0004] In order to facilitate the simultaneous shearing and punching of the copper busbar and improve the processing efficiency of the copper busbar, the present application provides an integrated copper busbar punching and shearing device for a distribution box.

[0005] The present application provides a copper busbar punching and shearing integrated device for a distribution box, which adopts the following technical solution:

[0006] A copper busbar punching and shearing integrated device for a distribution box, comprising a frame, a shearing assembly mounted on the frame in a lifting manner, a punching assembly mounted on the frame in a lifting manner, and a collecting assembly mounted on the frame, wherein a workbench is provided on the frame, and a clamping assembly for clamping the copper busbar is provided on the workbench;

[0007] The clamping assembly comprises a fixed block arranged on the workbench, a clamping block slidably arranged on the fixed block, and a sliding member for slidingly adjusting the clamping block, the copper row is placed on the fixed block, and the clamping block is movably fitted with a side close to the fixed block;

[0008] The shearing assembly comprises a fixed rod lifted and arranged on the frame, a shearing knife arranged on the fixed rod, and a lifting member for lifting and lowering the fixed rod. The shearing blades are provided in two groups, and the two groups of shearing blades are both in contact with the two opposite outer side walls of the fixed block and the clamping block. The end sides of the shearing blades are sharp, and the end sides of the shearing blades are in contact and tightly pressed against the top side of the copper bar.

[0009] The punching assembly includes an adjusting rod rotatably and liftably arranged on the frame, a punching head arranged on the adjusting rod, and a rotating member for controlling the punching head to punch holes, the punching head is located at the bottom side of the workbench, the shearing knife is located at the top side of the workbench, and the punching head is directly opposite to the shearing knife, and the frame is also provided with a synchronous moving member for controlling the synchronous movement of the shearing blade and the punching head;

[0010] When the shearing blade descends to shear the copper bar, the synchronous member drives the punching head to rise to perform a punching operation on the copper bar;

[0011] When shearing is completed, the shearing blade rises and the synchronous member drives the punching head to descend.

[0012] By adopting the above technical solution, when the copper busbar needs to be sheared, the technician will place the copper busbar to be processed on the fixed block, and slide the clamping block through the sliding piece until the clamping block and the fixed block can stably clamp the copper busbar, making it less likely to shake, thereby achieving subsequent shearing of the sides of the copper busbar and punching of the middle of the copper busbar.

[0013] After the copper busbar is clamped and fixed, the lifting part controls the fixing rod to descend, thereby driving the shear blade to descend. The shear blade fits tightly against the copper busbar, and the shear blade continues to descend to shear the copper busbar. Since the shear blade fits against the side of the fixing block, the accuracy of the entire shearing is improved.

[0014] At the same time, under the action of the moving part, the fixed rod descends and drives the adjusting rod to rise, driving the punching head to rise. At this time, under the action of the rotating part, the punching head punches holes in the copper bar to be punched, thereby realizing the simultaneous shearing of the copper bar. At the same time, under the action of the fixed block and the clamping block, the copper bar is not easy to bend upward or downward during shearing and punching, thereby realizing the simultaneous shearing and punching, and improving the production efficiency of the copper bar.

[0015] A common operation of performing shearing and punching simultaneously is to set shearing and punching on the same side, that is, both shearing and punching are performed from the top of the copper busbar from top to bottom. Here, if the shearing knife and the punching head are set on the same side of the copper busbar, the debris generated by the high-speed rotation during punching will be splashed in a divergent manner and adhere to the shearing blade to affect the subsequent shearing accuracy of the copper busbar. At the same time, both shearing and punching are in the form of stamping from top to bottom, which easily causes the copper busbar to bend upward.

[0016] In the present application, the shearing knife is arranged on the top side of the copper busbar, and the punching head is arranged on the bottom side of the copper busbar. At this time, the debris generated by the shearing knife during shearing is blocked by the fixed block and the clamping block, and is not easy to affect the normal punching of the punching head; at the same time, the debris generated by the punching head during punching is also blocked by the fixed block, thereby reducing the impact of the debris on the shearing knife and improving the shearing accuracy. When the punching head is arranged on the bottom side, since the debris generated by punching is large, the debris generated at this time automatically falls under the action of gravity, thereby facilitating the collection and recycling of the debris.

[0017] At the same time, the debris generated by the punching is collected by the provided collection component. Since copper is a precious metal, the provided collection component facilitates the recycling of the debris generated by the punching, thereby saving costs and reducing waste of resources.

[0018] Optionally, the collecting assembly includes a collecting box slidably arranged on the adjusting rod and a collecting plate rotatably arranged in the collecting box, and the collecting plates are provided with two groups, and the two groups of collecting plates are movably spliced ​​into a whole, and the collecting box is also provided with an adjusting member for adjusting the collecting plates, and the two groups of collecting plates are movably opened and closed, and the sides of the two collecting plates close to each other are movably fitted, and the end sides of the collecting plates are movably fitted with the punching head, and the punching head is movably located in the collecting box.

[0019] By adopting the above technical solution, when punching, the adjusting member rotates the two collecting plates toward the collecting box, thereby opening the collecting box, so that the debris generated by the punching at this time falls directly into the collecting box for collection. After the punching is completed, the adjusting member drives the two collecting plates to rotate in a direction close to each other until the two collecting plates rotate to horizontally enclose a whole. At this time, the end side of the collecting plate is in contact with the punching head, and the debris adhered to the outer peripheral wall of the punching head is cleaned. The debris adhered to the punching head falls onto the collecting plate. When punching is performed next time, the collecting plate rotates toward the collection box, so that the debris on the collecting plate falls into the collection box for collection.

[0020] Optionally, a limit rod is provided on the adjusting rod, and the limit rod is slidably inserted into the collecting box. An adjusting gear is provided at the rotating shaft of the collecting plate, and one end of the limit rod extending into the collecting box is meshed with the adjusting gear.

[0021] By adopting the above technical solution, when the synchronous part drives the adjusting rod and the punching head to rise, the other end of the limit rod slides in the collection box, and the limit rod engages with the adjusting gear, thereby realizing the rotation of the collection plate, and then realizing the collection of debris during punching. When punching is not performed, the two collection plates rotate to a horizontal position, and the punching head is located in the collection box, thereby reducing the problems of oil contamination, dust contamination, etc. caused by the long-term exposure of the punching head to the air, and reducing the rust of the punching head.

[0022] Optionally, the co-moving member includes a co-moving gear rotatably set on the frame, a first co-moving rod is provided on the fixed rod, and a second co-moving rod is provided on the adjusting rod, the first co-moving rod and the second co-moving rod are both engaged with the co-moving gear, and the first co-moving rod and the second co-moving rod are respectively located on opposite sides of the co-moving gear.

[0023] By adopting the above technical scheme, when the copper bar needs to be processed, the first synchronous rod on the fixed rod descends while the shear blade descends to shear the copper bar. Since the first synchronous rod is meshed with the synchronous gear, the synchronous gear is driven to rotate, and the synchronous gear drives the second synchronous rod located on the other side to slide, and the second synchronous rod drives the adjusting rod to rise, so that the punching head and the shearing knife are close to each other, and the shearing and punching of the copper bar are carried out synchronously; and after the shearing is completed, the shear blade is raised, driving the first synchronous rod to rise, and the first synchronous rod drives the synchronous gear to rotate in the opposite direction, so that the second synchronous rod descends, thereby realizing the synchronous movement of the punching head and the shear blade, which is convenient for taking out the processed copper bar and carrying out the processing operation of the next copper bar.

[0024] Optionally, a lubrication cavity is provided in the fixed block, a coating cavity is provided in the clamping block, and a coating hole connected to the coating cavity is opened on the clamping block, cooling oil is stored in the lubrication cavity, a connecting rod is provided on the clamping block, the connecting rod is hollow, one end of the connecting rod is connected to the coating cavity, the other end of the connecting rod is movably connected to the lubrication cavity, an adjustment plate is slidably arranged in the lubrication cavity, and the fixed block is also provided with a coating member for slidingly adjusting the adjustment plate.

[0025] By adopting the above technical solution, since a large amount of heat will be generated when the shearing knife shears the copper busbar, and since the shearing knife is sharp, if it is not cooled, the cutting edge of the shearing blade is prone to curling or chipping, so the shearing blade needs to be cooled.

[0026] After the shearing is completed, during the process of the shear blade rising, through the provided lubricating cavity and the lubricating oil stored in the lubricating cavity, when the shear blade shears the copper bar, the coating member drives the adjustment plate to slide upward in the lubricating cavity, so that the cooling oil in the lubricating cavity is squeezed into the coating cavity through the connecting rod. When the adjustment plate slides in the lubricating cavity, the cooling oil is squeezed through the coating hole onto the side wall of the shear blade to cool the shear blade;

[0027] When shearing is required, if a large amount of cooling oil adheres to the shear blade, it is easy to form an uneven coating on the surface of the shear blade, resulting in deviations during the shearing process. At this time, during the descent of the shear blade, the coating part controls the adjustment plate to slide downward, and negative pressure is generated in the lubrication cavity. At this time, when the clamping block fits the shear blade, negative pressure is generated in the coating hole to absorb and collect the cooling oil on the surface of the shear blade, and store it in the lubrication cavity, which not only reduces the waste of cooling oil and improves the reuse rate of cooling oil, but also facilitates the improvement of the shearing accuracy of the copper busbar.

[0028] Optionally, a connecting hole is provided on the fixed block, and the connecting hole is connected with the lubrication cavity. The connecting holes are provided with two groups, and the connecting rods are also provided with two groups. The two groups of connecting rods correspond to the two groups of connecting holes one by one, and the connecting rods are movably inserted into the connecting holes. A sealing plate is slidably provided at the connecting hole, and the sealing plate movably blocks the connecting hole, and the side of the sealing plate close to the connecting rod is inclined, and the inclined side of the sealing plate is movably pressed against the end side of the connecting rod.

[0029] By adopting the above technical scheme, a sealing plate is slidably arranged at the connecting hole, and when the clamping block and the fixed block do not clamp the copper busbar, the connecting rod is separated from the connecting hole, and the sealing plate seals the connecting hole, thereby sealing the cooling oil and reducing the pollution of the cooling oil by external dust, which affects the cooling quality of the cooling oil; when the clamping block and the fixed block are in contact with each other, the connecting rod is inserted into the connecting hole and pressed against the inclined side of the sealing plate, and the connecting rod continues to descend to drive the sealing plate to slide in the connecting hole, so that the sealing plate opens the connecting hole, thereby realizing the opening of the connecting hole and realizing stable connection between the connecting rod and the lubrication cavity in the fixed block, thereby facilitating the subsequent stable cooling and coating of the shear blade.

[0030] Optionally, a baffle is rotatably arranged in the coating cavity, and two groups of baffles are provided, and the two groups of baffles correspond one-to-one to the two groups of connecting rods, and the two groups of baffles rotate in opposite directions, and the baffles are movably fitted to the inner circumferential wall of the coating cavity.

[0031] By adopting the above technical solution, two groups of baffles with opposite rotation directions are arranged in the coating cavity. When the copper bar is sheared, the shear blade descends, driving the adjustment plate to slide in the lubrication cavity. At this time, one group of baffles fits the inner circumferential wall of the coating cavity, and the other group of baffles opens the coating cavity. At this time, negative pressure is generated at the coating hole, and the cooling oil on the surface of the shear blade is recovered and enters the lubrication cavity through the opened connecting rod for storage;

[0032] After the copper busbar is sheared and punched, there will be a high temperature on the shear blade. When the adjustment plate is driven to slide upward, the baffle corresponding to the other connecting rod opens the coating cavity, so that the cooling oil without metal debris is coated on the surface of the shear blade through the coating hole to cool the shear blade.

[0033] The coating cavity is blocked and opened by setting two sets of baffles, and the cooling oil with metal debris is adsorbed and precipitated in the lubrication cavity, thereby reducing the uneven cooling caused by the cooling oil with metal debris directly coating the shear blade surface, and facilitating the recovery of metal debris, thereby improving resource utilization.

[0034] Optionally, the adjusting member includes a limiting rod connected to the adjusting plate, the limiting rod protruding from the fixed block, a clamping rod being provided on the fixed rod, the clamping rod being movably fitted and clamped against a protruding end side of the limiting rod, and the clamping rod being elastically arranged on the side wall of the collection box.

[0035] By adopting the above technical solution, when the shear blade descends, the fixed rod drives the clamping rod to descend, and the clamping rod and the limit rod are pressed against each other, thereby driving the adjustment plate to slide in the lubrication cavity, realizing pressure regulation in the lubrication cavity, and realizing cooling of the shear blade and recycling of cooling oil.

[0036] Optionally, a filter is fixedly connected to the side wall of the lubrication cavity, and the filter blocks one of the connecting holes.

[0037] By adopting the above technical solution, after the cooling oil on the surface of the shear blade is adsorbed or recycled, the cooling oil is filtered through the set filter, so that the content of metal debris in the cooling oil flowing out from the coating hole is reduced, thereby improving the cooling effect of the cooling oil.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. Through the provided clamping assembly, shear blade, lifting part, punching head and synchronous moving part, the copper bar can be punched while being sheared, thereby improving the processing efficiency of the copper bar and facilitating the collection and recycling of the debris generated during punching and shearing;

[0040] 2. Through the sliding collection box, the rotating collection plate, the adjusting gear and the limit rod, when punching the copper bar, the collection plate rotates to open the top of the collection box, so as to collect the debris generated during the punching, and when the collection plate rotates to the horizontal position, the outer peripheral wall of the punching head is scraped to further reduce the influence of metal debris on subsequent punching;

[0041] 3. By setting the first synchronous rod, the second synchronous rod and the synchronous gear that is rotatably set, when the shear blade is driven to descend, the first synchronous rod descends, driving the synchronous gear to rotate, and then driving the second synchronous rod to rise, thereby realizing the synchronous driving of the shear blade and the punching head, saving power source.

[0047] The following is combined with Figure 1-4 This application is described in further detail.

[0048] The embodiment of the present application discloses a copper bar punching and shearing integrated device for a distribution box. Figure 1A copper busbar punching and shearing integrated device for a distribution box comprises a vertically fixed frame 1, a mounting frame 11 is fixedly connected to the top and bottom of the frame 1, a workbench 331 for placing the copper busbar is fixedly connected to the middle of the frame 1, a clamping component 3 is provided on the workbench 331, a shearing component 2 is lifted and arranged on the top mounting frame 11, a punching component 4 is lifted and arranged on the bottom mounting frame 11, and a collecting component 5 for collecting debris generated by the punching is also provided on the frame 1.

[0049] Reference Figure 1 and Figure 2 The clamping assembly 3 includes a fixed block 32 fixed on the workbench 331. The fixed block 32 is rectangular, and the length of the fixed block 32 is wider than the width of the copper busbar. A clamping block 31 is also slidably arranged on the workbench 331. The clamping block 31 corresponds to the fixed block 32. The clamping block 31 and the fixed block 32 are each provided with two groups. The two groups of clamping blocks 31 are arranged relatively to each other, and the two groups of fixed blocks 32 are also arranged relatively to each other, and the spacing between the outer side walls of the two groups of clamping blocks 31 is consistent with the width of the finished copper busbar. A sliding member 33 for slidingly adjusting the clamping block 31 is also provided on the workbench 331. The sliding member 33 includes an adjusting screw 332 which is rotatably connected to the clamping block 31 and threadedly penetrates the fixed block 32. There are four groups of adjusting screws 332, and the four groups of adjusting screws 332 are respectively arranged at the four corners of the fixed block 32; a space for placing the copper busbar is reserved between the fixed block 32 and the clamping block 31. When the copper busbar needs to be processed, the technician rotates the adjusting screw 332 to make the clamping block 31 move upward relative to the fixed block 32, so that a space for the copper busbar to be placed is left between the fixed block 32 and the clamping block 31. At this time, the technician inserts the copper busbar between the fixed block 32 and the clamping block 31, and then rotates the adjusting screw 332 to make the clamping block 31 and the fixed block 32 clamp the copper busbar.

[0050] Reference Figure 1 and Figure 2 The shearing assembly 2 includes a fixed rod 22 arranged on the top mounting frame 11 and a shearing blade 21 arranged on the bottom side of the fixed rod 22. The bottom end of the shearing blade 21 is sharp and the shearing blade 21 is in an "n" shape. The inner circumferential wall of the shearing blade 21 fits with the two opposite outer circumferential walls of the fixed block 32, and the bottom side of the shearing blade 21 fits tightly with the top side of the copper busbar. A lifting member 23 for lifting and lowering the fixed rod 22 is also provided on the top mounting frame 11. In the present application, the lifting member 23 is a screw motor.

[0051] At the same time, the punching assembly 4 includes an adjusting rod 41 which is lifted and arranged on the bottom mounting frame 11, and a punching head 42 is arranged on the top of the adjusting rod 41, and the punching head 42 is rotatably arranged on the adjusting rod 41. In the present application, the punching head 42 is a composite drill bit for drilling and tapping, and a rotating member 43 for rotating and adjusting the punching head 42 is also provided on the adjusting rod 41. In the present application, the rotating member 43 is a rotating motor 431, and at the same time, the frame 1 is also provided with a synchronous moving member 44 for synchronously adjusting the shear blade 21 and the punching head 42, referring to Figure 2 The synchronous member 44 includes a first synchronous rod 441 fixed on the fixed rod 22, and a second synchronous rod 442 fixed on the adjusting rod 41. A synchronous gear 443 is rotatably connected to the frame 1, and the rotation axis of the synchronous gear 443 is horizontal. The first synchronous rod 441 and the second synchronous rod 442 are both engaged with the synchronous gear 443, and the first synchronous rod 441 and the second synchronous rod 442 are respectively located on opposite sides of the synchronous gear 443.

[0052] When the copper bar needs to be processed, the first synchronous rod 441 on the fixed rod 22 descends while the shear blade 21 descends to shear the copper bar. Since the first synchronous rod 441 is meshed with the synchronous gear 443, the synchronous gear 443 is driven to rotate. The synchronous gear 443 drives the second synchronous rod 442 located on the other side to slide. The second synchronous rod 442 drives the adjusting rod 41 to rise, so that the punching head 42 and the shearing knife are close to each other, and the shearing and punching of the copper bar are carried out synchronously. After the shearing is completed, the shear blade 21 is raised, driving the first synchronous rod 441 to rise, and the first synchronous rod 441 drives the synchronous gear 443 to rotate in the opposite direction, so that the second synchronous rod 442 descends, thereby realizing the synchronous movement of the punching head 42 and the shear blade 21, so that the processed copper bar can be taken out and the next copper bar can be processed.

[0053] At the same time, since the common operation of performing shearing and punching simultaneously is to set shearing and punching to the same side, that is, both shearing and punching are performed from the top of the copper busbar from top to bottom, if the shearing knife and the punching head 42 are set on the same side of the copper busbar, the debris generated by the high-speed rotation during punching will be splashed in a divergent manner and adhere to the shearing blade 21, affecting the subsequent shearing accuracy of the copper busbar. At the same time, both shearing and punching are in the form of stamping from top to bottom, which easily causes the copper busbar to bend upward.

[0054] In the present application, the shearing knife is arranged on the top side of the copper busbar, and the punching head 42 is arranged on the bottom side of the copper busbar. At this time, the debris generated by the shearing knife during shearing is blocked by the fixed block 32 and the clamping block 31, and is not likely to affect the normal punching of the punching head 42; at the same time, the debris generated by the punching head 42 during punching is also blocked by the fixed block 32, thereby reducing the impact of the debris on the shearing knife and improving the shearing accuracy. When the punching head 42 is arranged on the bottom side, since there is more debris generated by punching, the debris generated at this time automatically falls under the action of gravity, thereby facilitating the collection and recycling of the debris.

[0055] Furthermore, since copper is a precious metal, in order to save resources and reduce the impact of debris generated during processing on shearing, a collection component 5 for collecting metal debris is also provided on the frame 1. Figure 2 , Figure 3 and Figure 4 The collecting assembly 5 includes a collecting box 51 slidably arranged on the adjusting rod 41, the punching head 42 is movably located in the collecting box 51, the top side of the collecting box 51 is open, and the top side of the collecting box 51 is rotatably connected with a collecting plate 52, and two groups of collecting plates 52 are provided, and the two groups of collecting boxes 51 correspond to the two opposite inner side walls of the collecting box 51 one by one and are rotatably connected, the two groups of collecting plates 52 are movably opened and closed on the top side of the collecting box 51, and the collecting plates 52 are provided with holes for the punching head 42 to movably pass through, and when the two groups of collecting plates 52 are rotated to horizontal, the two groups of collecting plates 52 are spliced ​​into a whole, and an adjusting member for rotating and adjusting the collecting plates 52 is also provided in the collecting box 51.

[0056] Reference Figure 3 The adjusting member includes a limiting rod 53 arranged on the mounting frame 11 on the bottom side, one end of the limiting rod 53 passes through and is inserted into the collecting box 51, and the collecting box 51 is elastically arranged on the mounting frame 11, and the top side of the collecting box 51 is movably fitted and tightly pressed against the bottom side of the fixing block 32, and an adjusting gear 54 is rotatably connected inside the collecting box 51, and the limiting rod 53 is meshed with the limiting gear, so that when the shearing blade 21 drives the punching head 42 to rise, the collecting box 51 is fitted with the bottom side of the fixing block 32, and the collecting box 51 slides relative to the adjusting rod 41, and the limiting rod 53 slides relative to the collecting box 51, and the limiting rod 53 drives the adjusting gear 54 to rotate, thereby driving the collecting plate 52 to rotate toward the direction inside the collecting box 51, thereby realizing the collection of debris during punching. When punching is not performed, the two collecting plates 52 are rotated to a horizontal position, and the punching head 42 is located in the collecting box 51 , so as to reduce the oil and dust contamination caused by the punching head 42 being exposed to the air for a long time, and reduce the rust of the punching head 42 .

[0057] Since the shearing process involves metal deformation, which will generate a lot of heat. Since the shear knife is sharp, if it is not cooled, the cutting edge of the shear blade 21 is prone to curling or defects. At this time, in order to facilitate the cooling of the shear blade 21, the fixed block 32 is hollow, and a lubrication cavity 6 is provided in the fixed block 32. Cooling oil is stored in the lubrication cavity 6. A coating cavity is provided in the clamping block 31. A coating hole 61 connected to the coating cavity is provided on the outer peripheral wall of the clamping block 31. A connecting rod 63 is fixedly connected to the fixed block 32. The connecting rod 63 is hollow, and a connecting hole 62 connected to the lubrication cavity 6 is provided on the clamping block 31. The connecting rod 63 is movably inserted into the connecting hole 62 and is connected to the lubrication cavity 6. The connecting hole 62 is slidable. A blocking plate 64 is movably provided, and the blocking plate 64 movably blocks the connecting hole 62. The top side of the blocking plate 64 is inclined, and the end side of the connecting rod 63 close to the fixed block 32 is pressed against the inclined side of the blocking plate 64, and an adjustment plate 34 is slidably provided in the lubrication cavity 6, and the sliding direction of the adjustment plate 34 is consistent with the height direction of the frame 1. At this time, a coating member for slidingly adjusting the adjustment plate 34 is also provided on the fixed block 32, and the coating member includes a locking rod 66 fixedly connected to the adjustment plate 34, and the locking rod 66 protrudes from the outer peripheral wall of the fixed block 32, and a tightening spring 68 is fixedly connected between the locking rod 66 and the workbench 331, and a tightening rod 67 is fixedly connected to the fixed rod 22, and the tightening rod 67 corresponds to the locking rod 66 and is movably pressed.

[0058] In the present application, two connecting rods 63 are provided, and the two connecting rods 63 are arranged at intervals along the length direction of the clamping block 31. Two groups of connecting holes 62 are provided, and the two connecting rods 63 correspond to the two connecting holes 62 one by one and are movably connected.

[0059] When the clamping block 31 and the fixed block 32 do not clamp the copper busbar, the connecting rod 63 is separated from the connecting hole 62, and the sealing plate 64 seals the connecting hole 62, thereby sealing the cooling oil and reducing the pollution of the cooling oil by external dust, which affects the cooling quality of the cooling oil; when the clamping block 31 and the fixed block 32 are in contact with each other, the connecting rod 63 is inserted into the connecting hole 62 and abuts against the inclined side of the sealing plate 64, and the connecting rod 63 continues to descend to drive the sealing plate 64 to slide in the connecting hole 62, so that the sealing plate 64 opens the connecting hole 62, thereby opening the connecting hole 62 and achieving stable connection between the connecting rod 63 and the lubrication cavity 6 in the fixed block 32, thereby facilitating the subsequent stable cooling and coating of the shear blade 21.

[0060] At the same time, the coating cavity in the present application is of "n" type, and the two ends of the coating cavity correspond one-to-one with the two connecting holes 62 and are movably connected, and the inner walls in the coating cavity that are respectively connected to the two connecting holes 62 are rotatably connected with baffles 65, and the end side of the baffle 65 away from its rotation axis is tightly fitted against the inner wall of the coating cavity, and the rotation directions of the two baffles 65 are opposite. At the same time, a filter screen 69 is fixedly connected to the position corresponding to one of the connecting holes 62 in the fixed block 32.

[0061] Two groups of baffles 65 with opposite rotation directions are arranged in rotation in the coating cavity. When the copper bar is sheared, the shear blade 21 descends, driving the adjustment plate 34 to slide in the lubricating cavity 6. At this time, one group of baffles 65 fits the inner wall of the coating cavity, and the other group of baffles 65 opens the coating cavity. At this time, negative pressure is generated at the coating hole 61, and the cooling oil on the surface of the shear blade 21 is recovered and enters the lubricating cavity 6 through the opened connecting rod 63 for storage;

[0062] After the copper busbar is sheared and punched, there will be a high temperature on the shear blade 21. At this time, when the adjustment plate 34 is driven to slide upward, the baffle 65 corresponding to the other connecting rod 63 opens the coating cavity, so that the cooling oil without metal debris is coated on the surface of the shear blade 21 through the coating hole 61, so as to cool the shear blade 21.

[0063] After the cooling oil on the surface of the shear blade 21 is adsorbed or recycled, the cooling oil is filtered through the filter screen 69, thereby reducing the content of metal debris in the cooling oil flowing out of the coating hole 61, thereby improving the cooling effect of the cooling oil.

[0064] The implementation principle of the integrated punching and shearing device for copper bars used in distribution boxes in the embodiment of the present application is as follows: when the copper bars need to be processed, the technician first rotates the adjusting screw 332 to leave a gap between the clamping block 31 and the fixing block 32 for placing and processing the copper bars. At this time, the technician places the copper bars to be processed between the clamping block 31 and the fixing block 32, and then rotates the adjusting screw 332 to clamp and fix the copper bars with the clamping block 31 and the fixing block 32. At this time, the shearing blade 21 is driven down by the screw motor to shear the copper bars. At this time, the punching head 42 is driven upward to shear the copper bars under the action of the first synchronous rod 441 and the second synchronous rod 442. Punching is performed to achieve simultaneous shearing and punching of the copper busbar. At the same time, when shearing is required, if a large amount of cooling oil adheres to the shear blade 21, it is easy to form an uneven coating on the surface of the shear knife, resulting in deviations during the shearing process. At this time, during the descent of the shear knife, the coating member controls the adjustment plate 34 to slide downward, and a negative pressure is generated in the lubrication cavity 6. At this time, when the clamping block 31 is in contact with the shear blade 21, a negative pressure is generated in the coating hole 61 to absorb and collect the cooling oil on the surface of the shear blade 21, and enter the lubrication cavity 6 for storage, which not only reduces the waste of cooling oil and improves the reuse rate of cooling oil, but also facilitates the improvement of the shearing accuracy of the copper busbar.

[0065] After the shearing is completed, during the rising process of the shear blade 21, through the provided lubricating cavity 6 and the lubricating oil stored in the lubricating cavity 6, when the shear blade 21 shears the copper bar, the coating member drives the adjusting plate 34 to slide upward in the lubricating cavity 6, thereby squeezing the cooling oil in the lubricating cavity 6 into the coating cavity through the connecting rod 63. When the adjusting plate 34 slides in the lubricating cavity 6, the cooling oil is squeezed through the coating hole 61 onto the side wall of the shear blade 21, thereby cooling the shear blade 21.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
