Description

Technical Field

[0001] The present invention relates to the technical field of copper strip processing, in particular to a copper strip processing device and a processing method. Background Art

[0002] During transformer installation, installing copper rings (also known as grounding rings or grounding grids) on the floor is a crucial safety measure, one of the most important measures to ensure stable operation and improve safety of power systems. It not only helps protect expensive electrical equipment from damage, but also provides a safer working environment for personnel.

[0003] In production practice, flat copper strips are used as raw materials. In the existing technology, a purely manual processing method is adopted. In order to avoid damaging the shape of the copper strip after bending, the workers first overlap the head and tail ends of the copper strip and then weld them. Then, the welded parts are polished and bent. In order to ensure good quality of the finished product, it is also necessary to strictly clean it before packaging. The existing processing method adopts multi-process decentralized operations. Frequent manual handling is not conducive to improving production efficiency, and it requires repeated positioning, which is time-consuming and labor-intensive. In addition, the multi-process decentralized operation method also has the problem of large space occupation and poor economy, and each process must be operated by a dedicated person. The processing quality is uneven and is not conducive to reducing labor costs. In the existing technology, the debris particles generated during welding and grinding cannot be cleaned in time, which is not only not conducive to creating a good processing environment, but also makes the cleaning process in the final link difficult and the cleaning effect is difficult to guarantee. Summary of the Invention

[0004] The present invention discloses a copper strip processing device and method, which solves the technical problems of copper strip processing in the prior art, such as time-consuming and labor-intensive processing, low efficiency, and uneven processing quality.

The technical solution adopted is as follows: A copper strip processing device comprises a frame, wherein the frame is provided with: The bending unit includes several bending rollers and a bending drive, wherein the several bending rollers form a channel for bending the copper strip, and the bending drive can transmit the rotational motion to at least one bending roller; preferably, the roller shaft of the bending roller is fixed, and the roller surface of the bending roller is detachably connected to the roller shaft through a key, so that it is convenient to disassemble and replace the roller surface to adapt to copper strips of different thicknesses; further preferably, an annular groove is formed on the roller surface, and the annular groove forms a channel for the bent copper strip, which can prevent the copper strip from jumping up and down and causing erroneous deformation during the process of passing through the bending unit, which is beneficial to ensuring the quality of the copper strip after bending.

[0005] The welding unit is arranged near the bending unit and includes a welding gun and a welding drive. The welding gun can be displaced under the action of the welding drive to perform welding processing on the leading end and the tail end of the copper strip; The dust suction unit comprises a dust suction fan and a filter element. A pipe connected to the dust suction fan forms a dust suction port at the welding unit. The air entering through the dust suction port is filtered by the filter element and then discharged outward.

[0006] On the basis of the above technical solution, several bending rollers are arranged on both sides of the copper strip, and the bending roller on at least one side is adjustable on the frame to process and form copper strips with different curvatures.

[0007] On the basis of the above technical solution, the bending roller is made of wear-resistant plastic material. Preferably, the roller surface of the bending roller is made of polytetrafluoroethylene or nylon material, which has good insulation and wear resistance.

The third bending roller is mounted on the other side of the copper strip and can be displaced forward and backward. The third bending roller is positioned near the center of the line connecting the first and second bending rollers. In this way, when the third bending roller approaches the copper strip to deform it, the copper strip on both sides of the third bending roller changes shape symmetrically, which is conducive to improving the bending quality.

[0009] On the basis of the above technical solution, a positioning roller group is provided on the frame on the entrance and / or exit side of the channel for bending the copper strip to guide the copper strip to run along the set path. Preferably, the positioning roller group includes two first positioning rollers arranged one above the other, the axes of the two first positioning rollers are arranged horizontally, the two first positioning rollers clamp the copper strip and move the copper strip forward to ensure that the copper strip has good position accuracy, and facilitate the first or tail end of the copper strip after bending to smoothly enter the bending unit again. Furthermore, the first positioning roller is rotatable in the horizontal plane, so that the copper strip can be adaptively guided; or the positioning roller includes two second positioning rollers arranged front and back, the two second positioning rollers have the same structure as the bending rollers, and the two second positioning rollers are both displaceable in the horizontal plane to adapt to the processing of copper strips with different curvatures.

Preferably, the movable ends of the vertical displacement assembly and the front-to-back displacement assembly are horizontally rotatably connected, and / or the movable ends of the front-to-back displacement assembly and the left-to-right displacement assembly are swingably connected, providing greater flexibility.

[0013] On the basis of the above technical solution, the dust suction port is arranged under the workbench, and the pipe connected to the dust suction port includes a vertical section and a horizontal section connected in sequence. Under the action of the dust suction fan, particulate matter falls into the horizontal section of the pipe or is filtered out with the air through the filter element.

On the one hand, it is beneficial to gather the particulate dust generated by welding or grinding to prevent it from overflowing, and on the other hand, it prevents the air containing particles from diffusing upward. The design is reasonable. The perforated plate on the shell near the hanging rack is convenient to use.

[0015] A copper strip processing method, using the copper strip processing device as described above, comprises the following steps: S1.

[0018] The bending unit of the present invention includes a plurality of bending rollers, which are arranged on both sides of the copper strip, and the position of the bending roller on at least one side is adjustable. This makes it easy to clamp the head end of the copper strip, and can also be used to form copper strips with different curvatures, which has good applicability.

The three bending rollers 21, 22, 23 are used to form a channel for bending the copper strip. In this embodiment, the three bending rollers 21, 22, 23 are respectively the first bending roller 21, the second bending roller 22 and the third bending roller 23. The first bending roller 21 and the second bending roller 22 are fixed on one side of the copper strip and can rotate under the action of the bending drive. The bending drive includes a motor fixed on the frame, and the motor transmits the rotational motion to the first bending roller 21 and the second bending roller 22 through a gear transmission assembly, so that the two bending rollers 21 and 22 rotate in the same direction and at the same speed; The third bending roller 23 is arranged on the other side of the copper strip so as to be displaceable forward and backward in the horizontal plane via a third screw transmission assembly. The third bending roller 23 is arranged near the center of the line connecting the first bending roller 21 and the second bending roller 22. In this way, the first bending roller 21 and the second bending roller 22 are symmetrically arranged on both sides of the central axis of the third bending roller 23. In this way, when the third bending roller 23 approaches the copper strip and deforms the copper strip, the shape of the copper strip on both sides of the third bending roller 23 changes symmetrically, which is conducive to improving the bending quality. Among them, the third screw transmission assembly includes a third screw and a third screw nut that cooperates with the third screw. The two ends of the third screw are rotatably connected to the frame. The third screw nut is slidably connected to the frame 1. The third bending roller 23 is fixedly connected to the third screw nut downward. A scale is provided on the frame table at the third screw nut to accurately control the forward and backward displacement of the third bending roller 23 to process and form copper strips with different curvatures.

[0028] In other embodiments of the present invention, multiple groups of bending units 2 may be provided circumferentially to better bend the shaped copper strip.

[0029] In this embodiment, the first bending roller 21 and the second bending roller 22 have the same structure. The roller shaft 212 of the first bending roller 21 is fixed in position, and the roller surface 211 of the first bending roller 21 is detachably connected to the roller shaft 212 through a key.

[0030] In this embodiment, annular grooves are formed on the roller surfaces of the first bending roller 21, the second bending roller 22 and the third bending roller 23. The annular grooves form a channel for the bent copper strip, which can prevent the copper strip from jumping up and down and causing incorrect deformation during the process of passing through the bending unit, which is beneficial to ensuring the quality of the copper strip after bending.

[0031] In this embodiment, the three-way bending rollers 21, 22, and 23 have the same structure, and the roller surfaces are all made of wear-resistant plastic material. Specifically, the roller surfaces of the three-way bending rollers 21, 22, and 23 are made of polytetrafluoroethylene or nylon material, which has good insulation and wear resistance and a long service life.

[0032] like Figure 4 and 5 As shown, in other embodiments of the present invention, a positioning roller set 24 is provided on the frame 1 at the entrance and / or exit side of the channel for bending the copper strip to guide the copper strip to run along the set path. Figure 4As shown, the positioning roller group 24 includes two first positioning rollers arranged up and down, and the axes of the two first positioning rollers are arranged horizontally. The two first positioning rollers clamp the copper strip and move the copper strip forward to ensure that the copper strip has good position accuracy, which facilitates the head end or tail end of the bent copper strip to smoothly enter the bending unit again. Furthermore, the first positioning rollers are rotatable in the horizontal plane. In this way, for copper strips with different curvatures, the two first positioning rollers can adapt to the horizontal swing angle to better guide the copper strip; in another embodiment of the present invention, as Figure 5 As shown, the positioning roller group 24 can also include two second positioning rollers arranged in front and behind. The two second positioning rollers have the same structure as the bending rollers 21, 22, and 23, and the two second positioning rollers are both arranged to be displaceable in the horizontal plane to adapt to the processing of copper strips with different curvatures.

[0033] In addition, it also includes a first shield 7, one side of which is connected to the frame 1 and can be covered outside the bending unit 2 to relatively isolate the bending unit 2 from the external environment, and the first shield 7 is provided with a through hole for the copper strip to enter and exit; The welding unit 3 is arranged close to the bending unit 2. In this embodiment, the welding unit 3 is arranged on one side of the bending unit 2 and close to the copper strip extension section after the bending. Figure 6 As shown, it includes a welding gun 31 and a welding drive 34. The welding gun 31 can be displaced under the action of the welding drive to flexibly weld the leading and trailing ends of the copper strip; specifically, the welding drive 34 includes an up-down displacement component 341, a front-to-back displacement component 342, and a left-to-right displacement component 342. The welding gun 31 is connected to the moving end of the up-down displacement component 341, the up-down displacement component 341 is connected to the moving end of the front-to-back displacement component 342, and the front-to-back displacement component 342 is connected to the moving end of the left-to-right displacement component 343. The left-to-right displacement component 343 is arranged on the frame 1. In this way, the position of the welding gun can be flexibly adjusted by up-down, front-to-back, and left-to-right displacement, which is convenient to use. Among them, the up-down displacement component 341, the front-to-back displacement component 342, and the left-to-right displacement component 343 are all existing technologies, and those skilled in the art can select them according to their needs. In other embodiments of the present invention, the moving ends of the up-down displacement component 341 and the front-to-back displacement component 342 are horizontally rotatable, and / or the moving ends of the front-to-back displacement component 342 and the left-to-right displacement component 343 are swingably connected. In this way, the angle of the welding gun 31 can be flexibly adjusted, which is more convenient to use.

[0034] In this embodiment, a clamping member 6 is further included, and the welding unit further includes a workbench 32. Figure 6 As shown, the workbench 32 is fixed on the moving end of the front-rear displacement assembly 342, and the clamping member 6 is designed to fix the copper strip on the workbench 32 to complete the welding and manual polishing operations. The clamping member is a prior art and will not be described here. In this embodiment, the clamping member is an insulating and high-temperature resistant clip.

[0035] like Figure 6 As shown, the workbench 32 is embedded with a backing plate 33 for convenient welding and polishing. In this embodiment, the head end and the tail end of the copper strip are welded by tin soldering.

[0036] In this embodiment, the switch for controlling the opening and closing of the welding gun 31 is a foot-operated switch, which can free both hands during operation and assist in positioning the copper strip. The foot-operated switch is a prior art and will not be described in detail here.

[0037] In other embodiments of the present invention, an automatic polishing unit is further provided on the workbench 32 on the side of the welding unit 3 away from the bending unit 2. The automatic polishing unit is arranged above the dust suction port 41. The copper strip after welding can continue to move forward to the automatic polishing unit for polishing under the action of the bending drive. As one of the implementation methods, the automatic polishing unit includes one or more polishing heads, and multiple polishing heads contact the welding points on the copper strip downward and slide back and forth to complete the polishing operation.

[0038] The dust collection unit 4 includes a dust collection fan and a filter element. A dust collection port 41 is formed at the inlet of the pipe connected to the dust collection fan. The air entering through the dust collection port 41 is filtered by the filter element and then discharged outward. In this embodiment, the dust collection port 41 is arranged below the workbench 32. The pipe connected to the dust collection port 41 includes a vertical section 42 and a horizontal section 43 connected in sequence. The vertical section 42 and the horizontal section 43 are connected at the junction through an inclined plate, which is conducive to gathering the falling particles. The inclined plate basically covers the dust collection port 41. On the one hand, the particles with larger particle sizes fall into the horizontal section 43 of the pipe, which is convenient for timely cleaning and avoids wear of the filter element. On the other hand, the air flow is guided downward to complete the filtering process, which is conducive to creating a good working environment, preventing the particles mixed in the air from diffusing upward and being inhaled by workers, and improving the safety of use.

[0039] The switch for controlling the dust collection unit is designed to be turned on when the foot switch is turned on, and to be turned off when the automatic grinding unit is turned off, or when the manual grinding operation is completed.

[0040] In this embodiment, the dust removal unit 4 is covered with a shell, and the shell is fixedly connected to the frame, such as Figure 8 As shown, the front panel of the shell forms the back panel of the space where the welding unit 3 is located, and the dust removal unit 4 also includes an electromagnetic pulse component (not shown), which is used to instantly spray compressed air onto the filter element to remove particulate dust on the filter element. In addition, a collection tray (not shown) is provided under the filter element to collect particulate dust falling from the filter element. A door panel is provided on the back panel of the shell to facilitate the removal and placement of the collection tray.

[0041] The system also includes a second shield 8, which is fixed to the housing above the welding unit 3 and corresponds to the position of the dust suction port 41. The L-shaped structure formed by the second shield 8 and the housing helps to collect dust particles generated by welding or grinding, preventing them from escaping, and also prevents the upward diffusion of air containing particles, which is a reasonable design. The perforated plate on the housing near the hanging rack is convenient to use.

[0042] In addition, a support plate (not shown) is included, which is embedded with a number of universal balls for supporting the copper strip upward. Multiple support plates can be arranged circumferentially to provide good support for the copper strip extending outside the processing device and facilitate smooth movement of the copper strip when it is bent.

[0043] A copper strip processing method, using the copper strip processing device as described above, comprises the following steps: S1. The first end of the copper strip is first passed through the bending unit 2, and then the tail end of the copper strip is passed through the bending unit 2, so that the copper strip has a set curvature; in order to ensure a good forming effect of the copper strip after bending, the copper strip can be passed through the bending unit 2 repeatedly 2 to 3 times.

[0044] S2. After the copper strip is bent, when the tail end of the copper strip moves to the welding unit, at least one clamping member 6 is used to press the tail end of the copper strip against the workbench 32. Then, the bending drive continues to move, so that the head end of the copper strip continues to move forward under the action of the bending unit and overlaps with the head end of the copper strip. Then, the clamping member 3 is used to press the overlapping head and tail ends of the copper strip against the workbench 32 again, and then the bending drive is turned off. S3, after that, the welding driver 34 drives the welding gun 31 to move forward and backward, left and right, and up and down to get close to the copper strip; S4, the dust collection unit 4 works, and then the welding gun 31 starts welding the leading and trailing ends of the copper strip to complete the welding; S5. After cooling, manually polish the welding points at the head and tail ends of the copper strip. After polishing is completed, turn off the dust collection unit 4.
