Description

Technical Field

[0001] This utility model relates to the field of copper busbar forming technology, and in particular to a copper busbar forming structure. Background Technology

[0002] Copper busbars, also known as copper busbars or copper bars, are conductive materials used for power transmission and distribution. They are typically made of pure copper or copper alloys and possess good electrical conductivity, corrosion resistance, and mechanical strength.

[0003] Before some copper busbars are put into use, holes are drilled in their surface to facilitate installation, to fix the copper busbars with screws, and to facilitate electrical connection when the line is connected or passes through. According to the authorization announcement number "CN210995998U", a stamping structure for irregularly shaped copper busbars is disclosed, including a lower die base. A partition plate is fixedly installed at the center of the upper end face of the lower die base. Two symmetrically distributed dies are fixedly installed on the upper end face of the lower die base, and the partition plate is located between the two dies. A fixing mechanism is provided on the side of the die away from the partition plate. A support plate slides on the upper end face of the die. An electric telescopic rod is fixedly installed on the rear side wall of the lower die base. By setting two dies at the top of the lower die base, a copper plate to be processed can be placed on one die, fixed, and stamped. Then, another copper plate to be processed can be placed on the other die. This allows the punch to continue processing another copper plate after stamping one copper plate without stopping the machine. By repeating this operation, the number of downtimes in the stamping operation can be reduced, thereby improving work efficiency.

[0004] Currently, when drilling holes on the surface of copper busbars, multiple holes are drilled side by side to ensure uniform hole distribution, which facilitates subsequent installation and electrical connection. However, since there are a relatively large number of holes, drilling them one by one with a single drill bit would greatly delay production efficiency. If multiple punches are used to punch holes simultaneously, the dense punching force can easily cause deformation of the copper busbar, affecting the forming quality of the copper busbar. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a copper busbar forming structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a copper busbar forming structure, including an operating table, on which columns are symmetrically distributed and fixed along both sides of the upper end of the operating table, and the same top plate is fixedly installed on the upper ends of the two columns, and cylinders are fixedly installed through both sides of the top plate, and piston rods for extension and retraction are provided inside the cylinders, and connecting seats are fixedly installed at the ends of the piston rods, and lifting plates are fixedly installed between the two connecting seats;

[0007] The surface of the lifting plate is covered with several bearings arranged in two rows. The inner ring wall of each bearing is press-fitted and fixed with a linkage shaft. The lower end of the linkage shaft is fitted with a drill bit holder, and a drill rod is fixedly inserted into the drill bit holder.

[0008] Preferably, a bearing seat is fixedly installed on one side of the upper end of the lifting plate, and a drive shaft is rotatably installed inside the bearing seat. A motor is fixed to one side of the lifting plate by a bracket. The motor has a rotating shaft for driving inside, and the end of the rotating shaft is fixed to the drive shaft by a coupling.

[0009] Preferably, a drive pulley is fixedly sleeved on the surface of the drive shaft, a linkage pulley is fixedly installed on the upper end of the linkage shaft, a belt passes over the surface of the drive pulley, and several linkage pulleys arranged in the same row are connected to the drive pulley by the belt for transmission.

[0010] Preferably, a mold base is fixedly installed above the operating table, and a copper busbar placement groove is opened at the upper end of the mold base, with material picking notches on both sides of the copper busbar placement groove.

[0011] Preferably, the lower end of the mold base is provided with a waste channel, and the interior of the copper busbar placement groove is provided with a number of through holes. The position of any one of the through holes matches the position of the corresponding drill rod and is provided through the hole. The through hole is connected to the waste channel.

[0012] Preferably, a dust collection hood is fixedly installed on one side of the operating table, and a dust collection pipe is installed on the back interface flange of the dust collection hood.

[0013] Preferably, an air pump is fixedly installed on one side of the lower end of the operating table via a bracket. The air inlet of the air pump is connected to the flange at the end of the suction pipe away from the suction hood, and an air filter is connected to the flange at the air outlet of the air pump.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1.

[0016] 2. As described in 1, the mold base is equipped with a waste channel and a through hole. The waste generated during the drilling process can fall directly into the waste channel through the through hole, avoiding the accumulation of waste and affecting the processing. At the same time, the dust collection hood works in conjunction with the air pump to suck in the dust generated during drilling and filter it through the air filter element, effectively reducing environmental pollution and improving the working environment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-4 A copper busbar forming structure includes an operating table 1. Columns 11 are symmetrically distributed and fixed on both sides of the upper end of the operating table 1. The upper ends of the two columns 11 are fixedly installed with the same top plate 12. Cylinders 13 are fixedly installed through both sides of the top plate 12. A piston rod for extension and retraction is provided inside the cylinder 13, and a connecting seat 14 is fixedly installed at the end of the piston rod. A lifting plate 15 is fixedly installed between the two connecting seats 14. The extension and retraction of the piston rod of the cylinder 13 allows the drill rod 19 to move stably up and down with the lifting plate 15 when rotating to open a hole.

[0025] A number of bearings 16 are distributed throughout the surface of the lifting plate 15. The bearings 16 are arranged in two rows. A linkage shaft 17 is interference-fitted and fixed through the inner ring wall of the bearing 16. A drill bit holder 18 is assembled at the lower end of the linkage shaft 17. A drill rod 19 is fixedly inserted into the drill bit holder 18. The linkage shaft 17 can rotate stably based on the bearings 16. The drill bit holder 18 can ensure the stable installation of the drill rod 19.

[0026] The upper side of the lifting plate 15 is fixedly mounted with a bearing seat 2, and a drive shaft 21 is rotatably mounted inside the bearing seat 2. A motor 22 is fixed to one side of the lifting plate 15 by a bracket. The motor 22 has a rotating shaft for driving inside, and the end of the rotating shaft is fixed to the drive shaft 21 by a coupling. After the motor 22 is powered on, it can drive the rotating shaft and make the rotating shaft drive the drive shaft 21 to rotate, thereby enabling it to drive the drive pulley 23 to rotate stably.

[0027] The drive shaft 21 is fixedly fitted with a drive pulley 23, and the upper end of the linkage shaft 17 is fixedly mounted with a linkage pulley 24. The surface of the drive pulley 23 is covered by a belt 25. Several linkage pulleys 24 arranged in the same row are connected to the drive pulley 23 through the belt 25. The belt 25 can play a stable transmission role, so that the drive pulley 23 can drive multiple linkage pulleys 24 to rotate synchronously when transmitting power. Thus, the linkage shaft 17 can be rotated stably, and finally, multiple drill rods 19 can be rotated synchronously to perform hole opening operations.

[0028] The mold base 3 is fixedly installed above the operating table 1. The upper end of the mold base 3 is provided with a copper busbar placement groove 31. Both sides of the copper busbar placement groove 31 are provided with material removal notches 34. The copper busbar to be drilled can be placed inside the copper busbar placement groove 31. After the processing is completed, the copper busbar can be removed from the inside of the copper busbar placement groove 31 through the material removal notches 34.

[0029] The mold base 3 has a waste channel 32 at its lower end. The copper busbar placement groove 31 has several through holes 33 inside. The position of any one of the through holes 33 matches the position of the corresponding drill rod 19 and is set through it. The through hole 33 is connected to the waste channel 32. When the drill rod 19 is drilling, the through hole 33 can set the through copper busbar and allow the drill rod 19 to move through the through hole 33. The waste channel 32 can ensure that the waste material of the drilled hole is exposed.

[0030] The operating table 1 is fixedly installed with a dust hood 4 on one side. The dust hood 4 has a dust suction pipe 41 installed on the back interface flange. When dust is generated during drilling, the dust hood 4 can suck in the dust and filter out large lint and dust under the action of the air pump 42. The dust suction pipe 41 can ensure the stable delivery of airflow.

[0031] An air pump 42 is fixedly installed on one side of the lower end of the operating table 1 via a bracket. The air inlet of the air pump 42 is connected to the flange at the end of the suction pipe 41 away from the dust hood 4. The air outlet flange of the air pump 42 is connected to an air filter 43. When the power supply of the air pump 42 is turned on, the air pump 42 produces a suction effect, thereby sucking the fine drilling dust into the air filter 43 for collection and ensuring normal air circulation. The air filter 43 is a non-woven fabric filter.

[0032] In practice

[0033] This solution uses a motor 22 to drive a drive shaft 21 to rotate. A drive pulley 23, which is fixedly sleeved on the surface of the drive shaft 21, is connected to multiple linkage pulleys 24 arranged in the same row via a belt 25. The linkage pulleys 24 are fixed to the upper end of the linkage shaft 17. The linkage shaft 17 passes through the lifting plate 15 via a bearing 16 and achieves stable rotation. When the motor 22 starts, the drive pulley 23 drives the belt 25 to move, thereby synchronously driving all linkage pulleys 24 and the linkage shaft 17 to rotate. The drill bit seat 18 mounted at the lower end of the linkage shaft 17 fixes the drill rod 19, so that multiple drill rods 19 can rotate synchronously. At the same time, the cylinders 13 on both sides of the top plate 12 drive the connecting seat 14 and the lifting plate 15 to move up and down through the extension and retraction of the piston rod, thereby controlling the drill rod 19 to feed vertically while rotating, achieving precise drilling of the copper busbar in the copper busbar placement slot 31. After the drill rod 19 passes through the copper busbar, it enters the through hole 33. The waste is discharged through the waste channel 32, completing the efficient synchronous drilling operation.

[0034] The mold base 3 is fixed above the operating table 1. Its copper busbar placement groove 31 is used to place the copper busbar to be processed. The material removal notches 34 on both sides facilitate the removal of the copper busbar after processing. The through holes 33 opened inside the copper busbar placement groove 31 correspond one-to-one with the position of the drill rod 19, ensuring that the drill rod 19 can accurately penetrate the copper busbar and enter the through hole 33 when it is pressed down. The waste generated by drilling falls into the waste channel 32 through the through hole 33 and is discharged in a concentrated manner to avoid the accumulation of waste and affect the processing accuracy. The dust suction hood 4 on one side of the operating table 1, under the suction action of the air pump 42, sucks in the dust generated during the drilling process through the dust suction pipe 41 and delivers it to the air filter element 43 for filtration and collection. The air filter element 43 is made of non-woven fabric, which can effectively intercept fine dust and ensure a clean working environment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
