Abstract

The application relates to a copper bar shearing structure and relates to the technical field of power equipment processing, which comprises a base.

Description

Technical Field

[0001] This application relates to the field of power equipment processing technology, and in particular to a copper busbar shearing structure. Background Technology

[0002] In the field of power equipment manufacturing, copper busbars, as important conductive connection components, are widely used in high and low voltage switchgear, busbar trunking, and various power transmission systems. During the processing of copper busbars, it is often necessary to cut long copper busbars into smaller segments of specific lengths to meet practical application requirements. Currently common copper busbar cutting structures, such as those consisting of a base, guide rails, and a cutting structure, while achieving basic cutting functionality, have revealed numerous problems during long-term use.

[0003] In existing technologies, the shearing blade, as a key component directly cutting copper busbars, is prone to wear and dulling after frequent shearing operations, leading to a decline in shearing quality, such as burrs, uneven cuts, or even failure to cut the copper busbar smoothly. Furthermore, existing devices often suffer from unreasonable structural design when the shearing blade needs replacement, resulting in an extremely cumbersome replacement process. Some devices use complex bolt-fastening methods to mount the shearing blade to the shearing structure, requiring multiple tools for disassembly and installation, consuming significant time and manpower. Other devices have the shearing blade tightly integrated with other components, requiring the removal of numerous surrounding parts for replacement, increasing operational difficulty and potentially damaging other components during disassembly, severely impacting production efficiency and increasing production costs. Therefore, this paper proposes a copper busbar shearing structure. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this application is to provide a copper busbar shearing structure that solves the problems of cumbersome, time-consuming and labor-intensive shearing blade replacement in the prior art, saves replacement time and labor costs, and improves production efficiency.

[0006] The copper busbar shearing structure provided in this application adopts the following technical solution: it includes a base, an electric guide rail is fixedly connected to the upper end of the base, two sets of electric guide rails are symmetrically arranged on the upper end of the base, a sliding cap is slidably connected to the surface of each set of electric guide rails, a moving block is fixedly connected between the two sets of sliding caps, a fixed plate is fixedly connected to the front side of the moving block, a shearing blade is provided at the lower end of the fixed plate, a groove is opened on the lower surface of the fixed plate, a protrusion adapted to the groove is fixedly connected to the upper end of the shearing blade, through holes communicating with the groove are opened on both the left and right sides of the fixed plate, a limit rod is movably connected inside the through hole, a limit hole is opened on both the left and right sides of the protrusion, a handle is fixedly connected to one end of the limit rod, the other end of the limit rod passes through the limit hole, a spring passes through the surface of the limit rod, one end of the spring is fixedly connected to the side of the fixed plate, the other end of the spring is fixedly connected to the side of the handle, and a limit mechanism is provided on the upper surface of the base;

[0007] By adopting the above technical solution, and by setting up a groove and a protrusion, a limiting rod, a spring, and a handle, when the shearing blade needs to be replaced, the operator pulls the handle, causing the limiting rod to be pulled out of the limiting hole of the protrusion. At this time, the spring is stretched. Since the protrusion at the upper end of the shearing blade matches the groove on the lower surface of the fixing plate, after pulling out the limiting rod, the old shearing blade, along with the protrusion, can be directly removed from the groove. When replacing the new shearing blade, the protrusion of the new shearing blade is inserted into the groove, the handle is released, and under the elastic force of the spring, the limiting rod automatically passes into the limiting hole of the protrusion, completing the fixation. This structure requires no complicated tools, simplifies the shearing blade replacement process, solves the problems of cumbersome, time-consuming, and labor-intensive shearing blade replacement in the existing technology, saves replacement time and labor costs, and improves production efficiency.

[0008] Preferably, the limiting mechanism includes a support frame, and two sets of the support frames are symmetrically arranged on the upper surface of the base. An electric push rod is inserted inside each set of the support frames, and the output end of each set of the electric push rods is fixedly connected to a limiting plate.

[0009] By adopting the above technical solution, the support frame in the limiting mechanism provides stable support for the electric push rod, which can push the limiting plate to clamp the copper busbar. During the shearing process, the position of the limiting plate can be adjusted by the electric push rod to adapt to copper busbars of different sizes, ensuring that the copper busbar does not shift during shearing, thus improving the accuracy and stability of shearing and guaranteeing the shearing quality.

[0010] Preferably, a buffer layer is provided on the side of the limiting plate away from the electric push rod, and the buffer layer is made of rubber material.

[0011] By adopting the above technical solution, the buffer layer on the limiting plate is made of rubber material. When the limiting plate clamps the copper busbar, the buffer layer can make flexible contact with the surface of the copper busbar. This not only enhances the clamping effect of the copper busbar and prevents it from slipping, but also avoids damage to the surface of the copper busbar caused by hard contact between the limiting plate and the copper busbar, thus protecting the appearance and performance of the copper busbar.

[0012] Preferably, the shearing blade is made of high-speed steel, and the cutting edge of the shearing blade is provided with a wear-resistant coating.

[0013] By adopting the above technical solution, the shearing blade is made of high-speed steel, which has high hardness and wear resistance, and can withstand the wear of frequent copper busbar shearing. The wear-resistant coating at the cutting edge further improves the wear resistance of the cutting edge and slows down the rate at which the cutting edge becomes dull. This extends the service life of the shearing blade, reduces the frequency of replacement, and ensures the smoothness of the copper busbar cut during long-term shearing operations, reducing the probability of quality problems such as burrs on the cut.

[0014] Preferably, the inner wall of the groove is provided with anti-slip texture, and the outer wall of the protrusion is in close contact with the inner wall of the groove.

[0015] By adopting the above technical solution, the anti-slip texture on the inner sidewall of the groove fits tightly against the outer sidewall of the protrusion, increasing the friction between them. During the shearing operation, this effectively prevents the shearing blade from sliding or wobbling relative to the fixed plate, ensuring the stability of the shearing blade during operation and further improving the shearing accuracy and quality of the copper busbar.

[0016] Preferably, the surface of the handle is covered with an anti-slip sleeve made of silicone material.

[0017] By adopting the above technical solution, the anti-slip sleeve on the handle surface is made of silicone material, which has good anti-slip properties and flexibility. When the operator pulls the handle to change the shear blade, the anti-slip sleeve increases the friction between the hand and the handle, preventing the hand from slipping, making the operation more effortless and convenient, and improving the safety and efficiency of changing the shear blade.

[0018] Preferably, the movable block has weight-reducing holes inside, and the weight-reducing holes are distributed in a rectangular array.

[0019] By adopting the above technical solution, the weight-reducing holes inside the moving block are distributed in a rectangular array, which reduces the overall weight of the moving block. When the moving block is driven by the electric guide rail, the reduced weight reduces the load on the electric guide rail, making the movement of the moving block more flexible and smooth, reducing energy consumption, and also reducing wear on the connection between the moving block and the sliding cap, thus extending the service life of the components.

[0020] Preferably, the support frame is made of alloy steel.

[0021] By adopting the above technical solution, the support frame is made of alloy steel, which has high strength and rigidity. When the electric push rod pushes the limiting plate to clamp the copper busbar, the support frame can withstand the force transmitted by the electric push rod, avoiding deformation or damage to itself, thus ensuring the structural stability and operational reliability of the limiting mechanism and providing a solid guarantee for the stable limiting of the copper busbar.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This copper busbar shearing structure features a groove and protrusion, a limiting rod, a spring, and a handle. When the shearing blade needs replacement, the operator pulls the handle, causing the limiting rod to be pulled out of the limiting hole of the protrusion, thus stretching the spring. Since the protrusion at the upper end of the shearing blade matches the groove on the lower surface of the fixing plate, the old shearing blade, along with its protrusion, can be directly removed from the groove after the limiting rod is pulled out. To replace the new shearing blade, the protrusion of the new shearing blade is inserted into the groove, the handle is released, and the limiting rod automatically inserts into the limiting hole of the protrusion under the spring force, completing the fixation. This structure eliminates the need for complex tools, simplifying the shearing blade replacement process and solving the problems of cumbersome, time-consuming, and labor-intensive shearing blade replacement in existing technologies. It saves replacement time and labor costs, and improves production efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5This application will be described in further detail below.

[0032] Example 1: A copper busbar shearing structure, referring to Figure 1 , Figure 3 and Figure 4 The system includes a base 1, with an electric guide rail 2 fixedly connected to the upper end of the base 1. Two sets of electric guide rails 2 are symmetrically arranged on the upper end of the base 1. Sliding caps 3 are slidably connected to the surfaces of both sets of electric guide rails 2. A moving block 4 is fixedly connected between the two sets of sliding caps 3. A fixed plate 5 is fixedly connected to the front side of the moving block 4. A shearing blade 6 is located at the lower end of the fixed plate 5. A groove 7 is formed on the lower surface of the fixed plate 5. A protrusion 8, matching the groove 7, is fixedly connected to the upper end of the shearing blade 6. Through holes 9, communicating with the groove 7, are formed on both the left and right sides of the fixed plate 5. Limiting rods 10 are movably connected inside the through holes 9. The protrusion 8 is located on the left... Limiting holes 13 are provided on both the right and left sides. One end of the limiting rod 10 is fixedly connected to a handle 11, and the other end of the limiting rod 10 passes through the limiting hole 13. A spring 12 passes through the surface of the limiting rod 10. One end of the spring 12 is fixedly connected to the side of the fixing plate 5, and the other end of the spring 12 is fixedly connected to the side of the handle 11. A limiting mechanism 14 is provided on the upper surface of the base 1. The mechanism consists of a groove 7, a protrusion 8, a limiting rod 10, a spring 12, and a handle 11. When the shearing blade 6 needs to be replaced, the operator pulls the handle 11, which pulls the limiting rod 10 out of the limiting hole 13 of the protrusion 8. At this time, the spring 12 is stretched. Since the protrusion 8 at the upper end of the shearing blade 6 matches the groove 7 on the lower surface of the fixing plate 5, after the limiting rod 10 is pulled out, the old shearing blade 6 along with the protrusion 8 can be directly removed from the groove 7. When replacing the new shear blade 6, insert the protrusion 8 of the new shear blade 6 into the groove 7, release the handle 11, and under the elastic force of the spring 12, the limiting rod 10 automatically passes into the limiting hole 13 of the protrusion 8, completing the fixation. This structure requires no complicated tools, simplifies the replacement process of the shear blade 6, solves the problem of cumbersome, time-consuming and labor-intensive replacement of the shear blade 6 in the prior art, saves replacement time and labor costs, and improves production efficiency.

[0033] Reference Figure 1 and Figure 5The limiting mechanism 14 includes a support frame 1401, of which two sets are symmetrically arranged on the upper surface of the base 1. Each set of support frames 1401 has an electric push rod 1402 inserted inside. The output ends of both sets of electric push rods 1402 are fixedly connected to a limiting plate 1403. A buffer layer made of rubber is provided on the side of the limiting plate 1403 away from the electric push rod 1402. The support frame 1401 in the limiting mechanism 14 provides stable support for the electric push rod 1402, which can push the limiting plate 1403 to clamp the copper busbar. During the shearing process, the position of the limiting plate 1403 can be adjusted by the electric push rod 1402 to accommodate copper busbars of different sizes, ensuring that the copper busbar does not shift during shearing, improving the accuracy and stability of the shearing, and guaranteeing the shearing quality. The buffer layer on the limiting plate 1403, made of rubber, can flexibly contact the surface of the copper busbar when the limiting plate 1403 clamps it. It can enhance the clamping effect on the copper busbar, prevent the copper busbar from sliding, and avoid the limit plate 1403 from making hard contact with the copper busbar, thus preventing damage to the surface of the copper busbar and protecting the appearance and performance of the copper busbar.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The shearing blade 6 is made of high-speed steel. A wear-resistant coating is applied to the cutting edge of the shearing blade 6, and anti-slip textures are provided on the inner wall of the groove 7. The outer wall of the protrusion 8 fits tightly against the inner wall of the groove 7. High-speed steel has high hardness and wear resistance, capable of withstanding the wear of frequent copper busbar shearing. The wear-resistant coating at the cutting edge further enhances its wear resistance and slows down the dulling process. This extends the service life of the shearing blade 6, reduces replacement frequency, and ensures the smoothness of the copper busbar cut during long-term shearing operations, reducing the probability of burrs and other quality problems. The anti-slip textures on the inner wall of the groove 7 fit tightly against the outer wall of the protrusion 8, increasing the friction between them. During shearing operations, this effectively prevents the shearing blade 6 from sliding or shaking relative to the fixed plate 5, ensuring the stability of the shearing blade 6 during operation and further improving the shearing accuracy and quality of the copper busbar.

[0035] Reference Figure 1 , Figure 2 and Figure 5The handle 11 is covered with an anti-slip sleeve made of silicone. The moving block 4 has internal weight-reducing holes arranged in a rectangular array. The support frame 1401 is made of alloy steel. The anti-slip sleeve on the handle 11 is made of silicone, which has good anti-slip properties and is soft. When the operator pulls the handle 11 to change the shearing blade 6, the anti-slip sleeve increases the friction between the hand and the handle 11, preventing slippage and making operation more effortless and convenient. This improves the safety and efficiency of changing the shearing blade 6. The weight-reducing holes inside the moving block 4 are arranged in a rectangular array, reducing the overall weight of the moving block 4. When the electric guide rail 2 drives the moving block 4, the reduced weight lowers the load on the electric guide rail 2, making the movement of the moving block 4 more flexible and smooth, reducing energy consumption, and also reducing wear at the connection between the moving block 4 and the sliding cap 3, extending the service life of the components. The support frame 1401 is made of alloy steel, which has high strength and rigidity. When the electric push rod 1402 pushes the limiting plate 1403 to clamp the copper busbar, the support frame 1401 can withstand the force transmitted by the electric push rod 1402, avoiding deformation or damage to itself, ensuring the structural stability and operational reliability of the limiting mechanism 14, and providing a solid guarantee for the stable limiting of the copper busbar.

[0036] In this embodiment, a groove 7, a protrusion 8, a limiting rod 10, a spring 12, and a handle 11 are provided. When the shearing blade 6 needs to be replaced, the operator pulls the handle 11, causing the limiting rod 10 to be pulled out of the limiting hole 13 of the protrusion 8. At this time, the spring 12 is stretched. Since the protrusion 8 at the upper end of the shearing blade 6 is compatible with the groove 7 on the lower surface of the fixing plate 5, after the limiting rod 10 is pulled out, the old shearing blade 6 along with the protrusion 8 can be directly removed from the groove 7. When replacing the new shearing blade 6, the protrusion 8 of the new shearing blade 6 is inserted into the groove 7, the handle 11 is released, and under the elastic force of the spring 12, the limiting rod 10 automatically passes into the limiting hole 13 of the protrusion 8, completing the fixation. This structure does not require complex tools, simplifies the replacement process of the shearing blade 6, solves the problem of cumbersome, time-consuming, and labor-intensive replacement of the shearing blade 6 in the prior art, saves replacement time and labor costs, and improves production efficiency.

[0037] The implementation principle of this application embodiment is as follows: When performing copper busbar shearing, the copper busbar to be sheared is first placed on the upper surface of the base 1, directly below the shearing blade 6. Then, the electric push rod 1402 in the limiting mechanism 14 is activated. Under the support of the support frame 1401, the electric push rod 1402 begins to extend, pushing the limiting plate 1403 to move towards the copper busbar until the limiting plates 1403 on both sides clamp the copper busbar. At this time, the buffer layer on the side of the limiting plate 1403 away from the electric push rod 1402 contacts the surface of the copper busbar, completing the limiting and fixing of the copper busbar. Next, the electric guide rail 2 is activated. The sliding cap 3 slides down along the electric guide rail 2 under the drive of the electric guide rail 2. The sliding cap 3 drives the moving block 4 to move down synchronously. The moving block 4 then drives the fixed plate 5 fixedly connected to the front and the shearing blade 6 at the lower end of the fixed plate 5 to move down together. During this process, the weight-reducing holes inside the moving block 4 reduce the weight of the moving block 4, making the overall movement smoother. When the shearing blade 6 contacts the copper busbar, it continues to move downwards and cuts the copper busbar under pressure. Since the shearing blade 6 is made of high-speed steel and has a wear-resistant coating on the cutting edge, it can cut the copper busbar smoothly. At the same time, the anti-slip texture on the inner wall of the groove 7 fits tightly with the outer wall of the protrusion 8, ensuring the stability of the shearing blade 6 during the cutting process and preventing it from shaking. After the cutting is completed, the electric guide rail 2 drives the sliding cap 3 to slide upwards, causing the moving block 4, the fixing plate 5 and the shearing blade 6 to return to their original positions. The electric push rod 1402 retracts, causing the limiting plate 1403 to move away from the copper busbar, and the cut copper busbar can be removed. When the shearing blade 6 needs to be replaced, the operator holds the anti-slip sleeve on the surface of the handle 11 and pulls the handle 11 outwards. The handle 11 drives the limiting rod 10 to be pulled out of the limiting hole 13 of the protrusion 8. At this time, the spring 12 is stretched. Remove the old shear blade 6 along with the protrusion 8 from the groove 7 of the fixing plate 5, then insert the protrusion 8 of the new shear blade 6 into the groove 7, release the handle 11, the spring 12 returns to its original state, and drives the limiting rod 10 through the through hole 9 and into the limiting hole 13 of the protrusion 8, thus completing the replacement of the shear blade 6.
