[0001] The present invention belongs to the technical field of copper block processing, and particularly relates to a copper block cutting and forming device and a forming method for a high-voltage switch cabinet. Background Art

[0002] The copper blocks on the high-voltage switch cabinet usually refer to copper blocks or copper busbars. During the installation process of the high-voltage switch cabinet, copper blocks are often required to connect wires and are key components for conducting electricity, connecting, or contacting. When manufacturing copper blocks, processes such as cutting, punching, and bending are required.

[0003] When the copper block is being cut, the copper block will be extruded by the cutting blade, and the copper block has good ductility. After the copper block is cut, due to the lack of support in the end plane area of the copper block being cut, it may bulge out under the action of tensile stress. Moreover, high temperature will be generated during cutting, and the high temperature will further improve the ductility of the copper block, thereby promoting the situation of bulging out at the end plane of the copper block being cut. The bulging part may be in a relatively sharp state due to the action of shear force, which is likely to hurt workers, and the copper block is likely to cause the connecting wire to wear and break during subsequent use, thereby reducing the product quality.

[0013] A forming method for a copper block cutting and forming device on a high-voltage switch cabinet, the method is applied to the copper block cutting and forming device on the high-voltage switch cabinet as described above, and the method includes the following steps: Step S1: Preparation work, first place the copper block on the cutting table and fix it with a fixture; Step S2: Cutting, move the cutting blade without the grinding sheet through the moving seat to make the cutting blade move towards the copper block, and at the same time drive the cutting blade to rotate through the driving member, and the moving and rotating cutting blade cuts the copper block; Step S3: Reverse cutting. When there is still a short distance left on the copper block that has not been cut, move the cutting blade in the reverse direction. At the same time, move the cutting blade equipped with the grinding blade through the moving seat, so that the cutting blade equipped with the grinding blade moves towards the copper block and rotates, and cut the uncut part of the copper block. Step S4: Grinding. The cutting blade equipped with the grinding blade continues to move towards the copper block, so that the grinding blade grinds the end faces of the copper block cut into two sections to remove burrs. Step S5: Return both groups of cutting blades to their original positions, adjust the position of the long copper block, and repeat the above steps to continuously cut the long copper block.

[0014] The beneficial effects of the present invention are as follows: 1. In the present invention, the cutting blade is driven by the moving seat to move towards the copper block, and at the same time, the driving member drives the cutting blade to rotate. The rotating cutting blade cuts the copper block. When there is still a short distance left on the copper block that has not been cut, move the cutting blade in the reverse direction to withdraw it outside the copper block, and then move another group of cutting blades through another moving seat towards the copper block and cut the uncompletely cut part of the copper block. The stress fields generated by the two groups of cutting blades are superimposed in the copper block, so as to offset the unilateral tensile stress, and further reduce the situation that the end plane area of the copper block being cut protrudes outwards. 2. In the present invention, the two groups of cutting blades alternately cut the copper block, so that one group of cutting blades is always in an idle state during cutting. In this way, this group of cutting blades can have an intermittent period, and heat dissipation can be carried out on the cutting blades during this intermittent period, so as to avoid the cutting blades continuously operating to generate high temperature, avoid the high temperature increasing the ductility of the copper block, and further effectively avoid the situation that the end plane area of the copper block being cut protrudes outwards. 3. In the present invention, when the copper block is being cut, a convex part or burr that expands outwards may appear at its top. While the cutting blade is cutting, the high-pressure mechanism also moves accordingly, and the air jet pipe blows out high-pressure cold air towards the cut seam of the copper block. The high-pressure cold air can blow the convex part or burr towards the direction of the cutting blade, so that the convex part or burr moves towards the direction of the cutting blade, and the convex part or burr is removed by the cutting blade, thereby improving the product quality; the blown high-pressure cold air can cool the cutting blade and the copper block, so as to avoid the cutting blade operating to generate high temperature, avoid the high temperature increasing the ductility of the copper block, and further effectively avoid the situation that the end plane area of the copper block being cut protrudes outwards; the blown high-pressure cold air can blow the chips generated by cutting downwards, so as to effectively avoid the chips flying and hurting workers or damaging the surrounding equipment. 4. In the present invention, the surface of the cutting disc is always in a state of being wetted by the coolant, which can reduce the cutting temperature and prevent thermal damage to the cutting disc. Since copper has extremely high thermal conductivity, the heat generated by friction during cutting will be quickly transferred to the cutting disc, resulting in a sharp increase in the temperature of the cutting disc. The coolant removes heat through evaporation and forced convection, reducing the temperature of the cutting disc, avoiding phase change or softening of the material of the cutting disc due to high temperature, and preventing the ductility of the copper block from increasing at high temperature. It effectively avoids the situation where the end plane area of the copper block being cut protrudes outward, thus ensuring the cutting quality; it can reduce the wear of the cutting disc and extend its service life. Copper has strong ductility and is prone to form built-up edges on the surface of the cutting disc. The wet environment isolates the contact surface between the cutting disc and the debris through cooling and lubrication, reducing the adhesion of copper chips and lowering the incidence of built-up edges. The coolant forms a hydrodynamic film, reducing the friction coefficient between the cutting disc and the copper block, thereby reducing the wear of the cutting edge of the cutting disc; it can improve the quality of the end face of the copper block after cutting, suppress burrs and tearing. The wet environment reduces the fluctuation of the cutting force, reduces the plastic deformation at the edge of the copper block, and lowers the height of the burrs at the cut. The coolant flushes the chips to avoid scratching the machined surface; it can assist in chip evacuation and dust control. Under wet conditions, copper chips are more likely to break into short helical shapes or debris, avoiding long chips from winding around the cutting disc. The coolant can adsorb dust particles, reducing the dust concentration in the working area, thereby providing a better machining environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] As Figures 1-3 shown, a copper block cutting and forming device for a high-voltage switch box includes a base plate 1, a cutting table 2, a guide rail 3 and a fixture 17. The device further includes: Cutting blade 7. Two groups of moving seats 4 are slidably installed on the guide rail 3. A driving member 5 is installed on the moving seat 4, and the output end of the driving member 5 is installed with a cutting blade 7. A cutting seam 21 is opened on the cutting table 2, and the cutting blade 7 passes through the cutting seam 21 from bottom to top. The two groups of cutting blades 7 are respectively located on both sides of the copper block to be cut.

[0019] In actual application of this embodiment, first fix the long copper block to be cut through the fixture 17, then drive the cutting blade 7 to move towards the copper block through the moving seat 4, and at the same time, the driving member 5 drives the cutting blade 7 to rotate. The rotating cutting blade 7 cuts the copper block. When there is still a short distance left for the copper block to be cut, move the cutting blade 7 in the reverse direction to withdraw it outside the copper block, and then move another group of cutting blades 7 towards the copper block through the other moving seat 4 to cut the uncut part of the copper block. The stress fields generated by the two groups of cutting blades 7 are superimposed in the copper block, so as to offset the unilateral tensile stress, and further reduce the situation that the end plane area of the copper block being cut protrudes outwards; The two groups of cutting blades 7 alternately cut the copper block, so that there is always a group of cutting blades 7 in an idle state during cutting. In this way, this group of cutting blades 7 can have an intermittent period, and heat dissipation can be carried out on the cutting blades 7 during this intermittent period, so as to avoid the cutting blades 7 generating high temperature during continuous operation, avoid the high temperature increasing the ductility of the copper block, and further effectively avoid the situation that the end plane area of the copper block being cut protrudes outwards.

[0020] Further, grinding discs 8 are installed on both sides of one set of cutting discs 7. The diameter of the grinding discs 8 is smaller than that of the cutting discs 7, and the highest point of the grinding discs 8 is higher than the top of the copper block located on the cutting table 2.

[0021] In actual application of this embodiment, after the cutting disc 7 equipped with the grinding disc 8 finishes cutting the copper block, the cutting disc 7 can be continuously moved to make the grinding disc 8 grind the end faces of the copper block cut into two sections, removing the burrs on the end faces of the copper block. In this way, the burrs on the end faces of the copper block can be removed while cutting the copper block, thereby improving the product quality and eliminating the need to additionally set up a process for removing burrs, thus improving the processing efficiency of the copper block.

[0022] As Figures 1-6 shown, each set of cutting discs 7 corresponds to a set of high-pressure mechanisms 9. The high-pressure mechanism 9 includes: A U-shaped frame 91, one end of the U-shaped frame 91 is fixed on the structure that drives the cutting disc 7 to move, and a connecting plate 92 is provided at the other end of the U-shaped frame 91; Air guide pipes 93, two air guide pipes 93 are symmetrically fixed on the connecting plate 92, and the two air guide pipes 93 are located on both sides of the cutting disc 7; Air jet pipes 94, a number of air jet pipes 94 are connected to the air guide pipes 93, and the air jet pipes 94 face the cutting seam between the cutting disc 7 and the copper block.

[0023] In one case of this embodiment, the air guide pipes 93 are connected to an external air supply unit, and the supplied gas is high-pressure cold air.

[0024] In actual application of this embodiment, when the copper block is being cut, there may be protruding parts or burrs that expand outwards at its top. While the cutting disc 7 is cutting, the high-pressure mechanism 9 also moves accordingly, and the air jet pipes 94 blow high-pressure cold air towards the cutting seam of the copper block. The high-pressure cold air can blow the protruding parts or burrs towards the cutting disc 7, causing the protruding parts or burrs to move towards the cutting disc 7 and being removed by the cutting disc 7, thereby improving the product quality; The blown high-pressure cold air can cool the cutting disc 7 and the copper block, thereby preventing the cutting disc 7 from generating high temperature during operation and preventing the high temperature from increasing the ductility of the copper block, and further effectively preventing the end plane area of the copper block being cut from protruding outwards; The blown high-pressure cold air can blow the cutting debris downwards, effectively preventing the debris from splashing and injuring workers or damaging the surrounding equipment.

[0025] Further, a collar 95 is installed on the air jet pipe 94. A number of water outlet holes 951 are opened in the collar 95. The water outlet holes 951 are communicated with the air jet pipe 94, and a water supply pipe 952 is connected to the outside of the collar 95.

[0026] In one case of this embodiment, the water supply pipe 952 is connected to an external water supply unit to provide cooling liquid to the water supply pipe 952. The cooling liquid may be a water-based or oil-based lubricant, etc.

[0027] In actual application of this embodiment, the coolant enters the jet pipe 94 through the water outlet 951. Due to the interaction between the high-speed airflow and the coolant, the liquid coolant is broken into tiny droplets, so that the coolant sprayed from the jet pipe 94 is in an atomized state. The coolant in the atomized state can suppress the floating of dust generated during cutting, thereby providing a better processing environment, and the atomized coolant will be sprayed onto the surface of the cutting blade 7 and the copper block, which can further cool the cutting blade 7 and the copper block, thereby avoiding high temperature generated by the operation of the cutting blade 7 and avoiding high temperature to increase the ductility of the copper block, thereby further effectively avoiding the situation where the end plane area of ​​the copper block being cut protrudes outward. In addition, the atomized coolant can reduce the friction between the cutting blade 7 and the copper block, on the one hand, improving the cutting efficiency, and on the other hand, reducing the wear on the cutting blade 7.

[0028] like Figures 7-9 As shown, a protective cover 6 is installed outside the cutting blade 7, a partition 10 is arranged inside the protective cover 6, the cutting blade 7 passes through the partition 10, the partition 10 is located below the rotating axis of the cutting blade 7, a water storage chamber 61 is formed between the partition 10 and the inner cavity of the protective cover 6, and a coolant is stored in the water storage chamber 61, and a part of the cutting blade 7 is located in the coolant.

[0029] In one aspect of this embodiment, the coolant may be a water-based or oil-based lubricant or the like.

[0030] In actual application of this embodiment, the surface of the cutting blade 7 is always in a state of being soaked by the coolant, which can reduce the cutting temperature and prevent the cutting blade 7 from being thermally damaged. Since the thermal conductivity of copper is extremely high, the heat generated by friction during cutting will be quickly transferred to the cutting blade 7, causing the temperature of the cutting blade 7 to rise sharply. The coolant takes away the heat by evaporation and forced convection, and reduces the temperature of the cutting blade 7, thereby preventing the material of the cutting blade 7 from undergoing phase change or softening due to high temperature, preventing high temperature from increasing the ductility of the copper block, and effectively preventing the end plane area of ​​the copper block from protruding outwards, thereby ensuring the cutting quality. It can reduce the wear of the cutting blade 7 and extend its service life. Copper has strong ductility and is easy to form built-up edge on the surface of the cutting blade 7. The wet environment isolates the contact surface between the cutting blade 7 and the debris through cooling and lubrication, reduces the adhesion of copper chips, and reduces the incidence of built-up edge. The coolant forms a fluid dynamic film, which reduces the friction coefficient between the cutting blade 7 and the copper block, thereby reducing the wear of the cutting edge of the cutting blade 7. It can improve the quality of the rear end face of the copper block after cutting, suppress burrs and tearing, reduce the fluctuation of cutting force in a humid environment, reduce the plastic deformation of the edge of the copper block, reduce the height of the burr on the cut, and flush the chips with coolant to avoid scratching the processed surface; It can assist in chip evacuation and dust control. Under wet conditions, copper chips are more likely to break into short helical shapes or debris, avoiding long chips from winding around the cutting disc 7. The coolant can adsorb dust particles, reducing the dust concentration in the working area, thereby providing a better machining environment.

[0031] Furthermore, a floating plate 11 floats above the water stored in the water storage chamber 61. The cutting disc 7 passes through the floating plate 11. A plurality of push plates 111 are provided on the top of the floating plate 11. A plurality of moving chambers 101 are formed in the partition plate 10. The moving chambers 101 are located at the edge positions on the surfaces of the cutting disc 7. The two sides of the cutting disc 7 are respectively corresponding to the moving chambers 101. A plurality of through holes 102 are formed at the bottom of the partition plate 10. The through holes 102 communicate with the moving chambers 101. The push plates 111 extend into the moving chambers 101 through the through holes 102. A grinding disc 12 is slidably installed in the moving chambers 101. The grinding disc 12 is close to the cutting disc 7. An elastic member 121 is connected between the grinding disc 12 and the moving chambers 101. One side of the grinding disc 12 is an inclined surface, while the top of the push plate 111 is an inclined surface. The inclined surface of the grinding disc 12 abuts against the inclined surface of the push plate 111.

[0032] Furthermore, a vibration sensor 13 is installed in the grinding disc 12.

[0033] In one case of this embodiment, the vibration sensor 13 is a prior art and will not be elaborated here. The vibration sensor 13 is connected to an external receiver.

[0034] When this embodiment is actually applied, a part of the coolant ejected from the air jet pipe 94 flows into the protective cover 6 along the cutting seam 21 and finally enters the water storage chamber 61. In this way, the liquid level of the coolant in the water storage chamber 61 will slowly rise, causing the floating plate 11 to move upward. In this way, the push plate 111 will squeeze the grinding disc 12, causing the grinding disc 12 to move towards the cutting disc 7, so as to contact the cutting disc 7 and grind the edge of the cutting disc 7, keeping the edge of the cutting disc 7 sharp. This can effectively prevent the situation that the edge of the cutting disc 7 is too blunt and causes the end plane of the cut copper block to bulge outwards; A drain pipe 62 is installed on the protective cover 6. Together with the continuous consumption of the coolant by the cutting disc 7, the liquid level of the coolant will slowly drop after rising, so that the grinding disc 12 intermittently approaches the cutting disc 7 and intermittently grinds the cutting disc 7; When the grinding disc 12 contacts the cutting disc 7, the grinding disc 12 will generate vibration. At this time, the vibration sensor 13 will transmit a signal to the receiver, indicating that the thickness of the cutting disc 7 is qualified. If the vibration sensor 13 does not transmit a signal to the receiver for a long time, it means that the thickness of the cutting disc 7 is slowly decreasing, which will affect the cutting effect, thus prompting the worker to replace the cutting disc 7.

[0035] Such as Figure 3 and Figure 4As shown in the figure, a straight tube 14 is provided outside the protective cover 6. The straight tube 14 is communicated with the inside of the protective cover 6. A partition plate 10 is located below the straight tube 14. The output end of the driving member 5 is further provided with a turbine fan 15, and the turbine fan 15 is located inside the straight tube 14.

[0036] In actual application of this embodiment, while the cutting blade 7 rotates, the turbine fan 15 also rotates. In this way, the turbine fan 15 will dissipate heat from the cutting blade 7, avoiding high temperature from increasing the ductility of the copper block, thereby further effectively avoiding the situation that the end plane area of the cut copper block protrudes outwards. At the same time, the turbine fan 15 will also cool down the coolant, thereby ensuring the use effect of the coolant.

[0037] A forming method for a copper block cutting and forming device on a high-voltage switch cabinet. The method is applied to the copper block cutting and forming device on the above-mentioned high-voltage switch cabinet. The method includes the following steps: Step S1: Preparation work. First, place the copper block on the cutting table 2 and fix it with the fixture 17. Step S2: Cutting. Move the cutting blade 7 without the grinding blade 8 through the moving seat 4 to make the cutting blade 7 move towards the copper block. At the same time, drive the cutting blade 7 to rotate through the driving member 5. The moving and rotating cutting blade 7 cuts the copper block. Step S3: Reverse cutting. When there is still a small distance left for the copper block to be cut, move the cutting blade 7 in the reverse direction. At the same time, move the cutting blade 7 with the grinding blade 8 through the moving seat 4 to make the cutting blade 7 with the grinding blade 8 move towards the copper block and rotate, and cut the uncut part of the copper block. Step S4: Grinding. The cutting blade 7 with the grinding blade 8 continues to move towards the copper block, so that the grinding blade 8 grinds the end faces of the copper block cut into two sections to remove burrs. Step S5: Make both groups of cutting blades 7 return to their original positions, adjust the position of the long copper block, and repeat the above steps to continuously cut the long copper block.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
