Description

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

[0002] The copper blocks on high-voltage switchgear boxes usually refer to copper blocks or copper busbars. During the installation of high-voltage switchgear boxes, copper blocks are often needed to connect wires and are key components for electrical conduction, connection, or contact. Manufacturing these copper blocks requires cutting, punching, and bending.

[0003] When the copper block is cut, it will be squeezed by the cutting blade, and the copper block has good ductility. After the copper block is cut, the cut end plane area of ​​the copper block lacks support and may bulge outward due to tensile stress. In addition, high temperature will be generated during cutting, and high temperature will further increase the ductility of the copper block, thereby promoting the cut end plane of the copper block to bulge outward. The protruding part may be in a relatively sharp state due to the shear force, which can easily injure workers. In addition, the copper block is prone to wear and breakage of the connecting wires during subsequent use, thereby reducing product quality. Summary of the Invention

[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, a moving seat drives the cutting blades to move toward the copper block, while a driving member drives the cutting blades to rotate. The rotating cutting blades cut the copper block. When a small distance of the copper block remains to be cut, the cutting blades are moved in the opposite direction to withdraw from the copper block. Then, another moving seat moves another set of cutting blades toward the copper block to cut the uncut portion of the copper block.

[0026] 2. In the present invention, two groups of cutting blades cut the copper block alternately, so that one group of cutting blades is always idle during cutting.

[0027] 3. In the present invention, when the copper block is cut, outward-extending protrusions or burrs may appear on the top of the copper block. While the cutting blade is cutting, the high-pressure mechanism also moves, and the air jet blows high-pressure cold air toward the slit of the copper block. The high-pressure cold air can blow the protrusions or burrs toward the cutting blade, so that the protrusions or burrs move toward the cutting blade, and the protrusions or burrs are removed by the cutting blade, thereby improving product quality; the blown high-pressure cold air can cool the cutting blade and the copper block, thereby avoiding high temperatures generated by the operation of the cutting blade, and avoiding high temperatures that increase the ductility of the copper block, thereby further effectively preventing the flat end area of ​​the copper block from protruding outwards; the blown high-pressure cold air can blow the debris generated by cutting downward, thereby effectively preventing the debris from flying and injuring workers or damaging surrounding equipment;

[0028] 4. In the present invention, the surface of the cutting blade is always in a state of being soaked in coolant, which can reduce the cutting temperature and prevent the cutting blade from being damaged by heat. Since the thermal conductivity of copper is extremely high, the heat generated by friction during cutting will be quickly transferred to the cutting blade, causing the temperature of the cutting blade to rise sharply. The coolant takes away the heat by evaporation and forced convection, lowering the temperature of the cutting blade, avoiding the phase change or softening of the cutting blade material due to high temperature, avoiding the high temperature to increase the ductility of the copper block, and effectively avoiding the situation where the end plane area of ​​the copper block being cut protrudes outward, thereby ensuring the cutting quality; it can reduce the wear of the cutting blade and extend the service life. Copper has strong ductility and is easy to form built-up edge on the surface of the cutting blade. The wet environment is Cooling and lubrication isolate the contact surface between the cutting disc and the debris, reducing the adhesion of copper chips and the incidence of built-up edge. The coolant forms a fluid dynamic film to reduce 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 rear end face of the copper block after cutting, suppress burrs and tears, reduce cutting force fluctuations in a wet environment, reduce plastic deformation of the edge of the copper block, and reduce the height of the incision burr. The coolant flushes the chips to avoid scratching the processed surface. It can assist in chip removal and dust control. Under wet conditions, copper chips are more likely to break into short spirals or debris, avoiding long chips from wrapping around the cutting disc. The coolant can absorb dust particles to reduce the dust concentration in the working area, thereby providing a better processing environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] like Figure 1-Figure 3 As 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 clamp 17, and the device also includes:

[0042] 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, a cutting blade 7 is installed on the output end of the driving member 5, a cutting slot 21 is opened on the cutting table 2, and the cutting blade 7 passes through the cutting slot 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.

[0043] In actual application of this embodiment, the long copper block to be cut is first fixed by the clamp 17, and then the cutting blade 7 is driven to move toward the copper block by the movable seat 4. At the same time, the driving member 5 drives the cutting blade 7 to rotate, and the rotating cutting blade 7 cuts the copper block. When there is a small distance of the copper block that has not been cut, the cutting blade 7 is moved in the opposite direction to withdraw it from the outside of the copper block. Then, another set of cutting blades 7 is moved toward the copper block by another movable seat 4 to cut the uncut part of the copper block. The stress fields generated by the two sets of cutting blades 7 are superimposed in the copper block, thereby offsetting the unilateral tensile stress, thereby reducing the outward protrusion of the flat area of ​​the cut end of the copper block.

[0044] The two groups of cutting blades 7 cut the copper block alternately, so that one group of cutting blades 7 is always idle during cutting, so that this group of cutting blades 7 has an interval period, during which the cutting blades 7 can be cooled, thereby avoiding the high temperature generated by the continuous operation of the cutting blades 7, and avoiding the high temperature increasing 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.

[0045] Furthermore, 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 the diameter of the cutting discs 7 , and the highest point of the grinding discs 8 is higher than the top of the copper block on the cutting table 2 .

[0046] In actual application of this embodiment, after the cutting blade 7 equipped with the grinding blade 8 completes cutting of the copper block, the cutting blade 7 can continue to be moved so that the grinding blade 8 can grind the end face of the copper block cut into two sections to remove the burrs on the end face of the copper block. In this way, the burrs on the end face of the copper block can be removed while the copper block is being cut, thereby improving product quality without the need for an additional burr removal process, thereby improving the processing efficiency of the copper block.

[0047] like Figures 1-6 As shown, each set of cutting blades 7 corresponds to a set of high-voltage mechanisms 9, and the high-voltage mechanisms 9 include:

[0048] A U-shaped frame 91, one end of which is fixed to the structure that drives the cutting blade 7 to move, and the other end of the U-shaped frame 91 is provided with a connecting plate 92;

[0049] Air guide tubes 93: Two air guide tubes 93 are symmetrically fixed on the connecting plate 92, and the two air guide tubes 93 are located on both sides of the cutting blade 7;

[0050] The air injection pipe 94 is connected to the air guide pipe 93. The air injection pipe 94 is directed toward the slit between the cutting blade 7 and the copper block.

[0051] In one aspect of this embodiment, the air guide pipe 93 is connected to an external air supply unit, and the supplied air is high-pressure cold air.

[0052] In actual application of this embodiment, when the copper block is cut, outward-extending protrusions or burrs may appear on the top of the copper block. While the cutting blade 7 is cutting, the high-pressure mechanism 9 also moves, and the air jet 94 blows high-pressure cold air toward the slit of the copper block. The high-pressure cold air can blow the protrusions or burrs toward the cutting blade 7, causing the protrusions or burrs to move toward the cutting blade 7, and the protrusions or burrs are removed by the cutting blade 7, thereby improving product quality.

[0053] The high-pressure cold air blown out can cool the cutting blade 7 and the copper block, thereby preventing the cutting blade 7 from generating high temperature during operation, preventing high temperature from increasing the ductility of the copper block, and further effectively preventing the flat end area of ​​the copper block from protruding outwards.

[0054] The high-pressure cold air blown out can blow the debris generated by cutting downwards, which effectively prevents the debris from flying and injuring workers or damaging surrounding equipment.

[0055] Furthermore, a collar 95 is installed on the air jet pipe 94 , and a plurality 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 .

[0056] In one case of this embodiment, the water supply pipe 952 is connected to an external water supply unit to provide cooling liquid for the water supply pipe 952 . The cooling liquid may be a water-based or oil-based lubricant, etc.

[0057] In actual application of this embodiment, the coolant enters the air 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 air 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 cutting blade 7 during operation, and avoiding high temperature increasing 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.

[0058] like Figure 7-Figure 9 As shown, a protective cover 6 is installed outside the cutting blade 7, and a partition 10 is provided 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. Coolant is stored in the water storage chamber 61, and part of the cutting blade 7 is located in the coolant.

[0059] In one aspect of this embodiment, the coolant may be a water-based or oil-based lubricant, or the like.

[0060] In actual application of this embodiment, the surface of the cutting blade 7 is always in a state of being soaked in coolant, which can reduce the cutting temperature and prevent the cutting blade 7 from being thermally damaged. Since copper has an extremely high thermal conductivity, 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 removes the heat through evaporation and forced convection, thereby reducing the temperature of the cutting blade 7, 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 flat end area of ​​the copper block from protruding outwards, thereby ensuring cutting quality.

[0061] 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, reducing the adhesion of copper chips and 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 on the cutting edge of the cutting blade 7.

[0062] It can improve the quality of the rear end face of the copper block after cutting, suppress burrs and tears, 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 incision burr, and flush the chips with coolant to avoid scratching the processed surface;

[0063] It can assist in chip removal and dust control. Under wet conditions, copper chips are more likely to break into short spirals or debris, preventing long chips from wrapping around the cutting blade 7. The coolant can absorb dust particles, reducing the dust concentration in the working area, thereby providing a better processing environment.

[0064] Furthermore, a float 11 floats above the water stored in the water storage chamber 61, and the cutting blade 7 passes through the float 11. A number of push plates 111 are arranged on the top of the float 11. A number of movable chambers 101 are opened in the partition 10. The movable chamber 101 is located at the edge of the surface of the cutting blade 7. There are movable chambers 101 on both sides of the cutting blade 7. A number of through holes 102 are opened at the bottom of the partition 10, and the through holes 102 are connected with the movable chamber 101. The push plate 111 extends into the movable chamber 101 through the through holes 102. A grinding disc 12 is slidably installed in the movable chamber 101. The grinding disc 12 is close to the cutting blade 7. An elastic member 121 is connected between the grinding disc 12 and the movable chamber 101. One side of the grinding disc 12 is an inclined surface, and the top of the push plate 111 is also an inclined surface. The inclined surface of the grinding disc 12 is offset from the inclined surface of the push plate 111.

[0065] Furthermore, a vibration sensor 13 is installed in the grinding disc 12 .

[0066] In one case of this embodiment, the vibration sensor 13 is a prior art and will not be described in detail here. The vibration sensor 13 is connected to an external receiver.

[0067] In actual use of this embodiment, a portion of the coolant ejected from the air jet pipe 94 flows into the protective cover 6 along the cutting slit 21 and finally enters the water storage chamber 61. As a result, the coolant level in the water storage chamber 61 gradually rises, causing the floating plate 11 to move upward. In this way, the push plate 111 squeezes the grinding disc 12, causing the grinding disc 12 to move toward the cutting blade 7, thereby contacting the cutting blade 7 and grinding the edge of the cutting blade 7, so that the edge of the cutting blade 7 remains sharp. This can effectively prevent the edge of the cutting blade 7 from being blunt, which may cause the flat end of the copper block to bulge outward.

[0068] A drain pipe 62 is installed on the protective cover 6, which cooperates with the cutting blade 7 to continuously consume the coolant, so that the coolant level rises and then slowly drops, so that the grinding disc 12 intermittently approaches the cutting blade 7 and realizes intermittent grinding of the cutting blade 7;

[0069] When the grinding disc 12 contacts the cutting blade 7, the grinding disc 12 will vibrate, and the vibration sensor 13 will transmit a signal to the receiver at this time, which means that the thickness of the cutting blade 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 blade 7 is gradually decreasing, which will affect the cutting effect, thereby prompting the worker to replace the cutting blade 7.

[0070] like Figure 3 and Figure 4 As shown, a straight cylinder 14 is provided on the outside of the protective cover 6 , the straight cylinder 14 is communicated with the inside of the protective cover 6 , the partition 10 is located below the straight cylinder 14 , and a turbofan 15 is also installed at the output end of the driving member 5 , and the turbofan 15 is located inside the straight cylinder 14 .

[0071] In actual application of this embodiment, the turbine fan 15 rotates as the cutting blade 7 rotates. In this way, the turbine fan 15 will dissipate heat for the cutting blade 7, thereby preventing high temperature from increasing the ductility of the copper block, thereby further effectively preventing the end plane area of ​​the copper block from protruding outward after being cut. At the same time, the turbine fan 15 will also cool the coolant, thereby ensuring the use effect of the coolant.

[0072] A forming method for a copper block cutting and forming device for a high-voltage switch box, the method being applied to the above-mentioned copper block cutting and forming device for a high-voltage switch box, the method comprising the following steps:

[0073] Step S1: Preparation: First, place the copper block on the cutting table 2 and fix it with the clamp 17;

[0074] Step S2: Cutting, the cutting disc 7 without the grinding disc 8 is moved by the moving seat 4, so that the cutting disc 7 moves toward the copper block, and the cutting disc 7 is driven to rotate by the driving member 5, so that the moving and rotating cutting disc 7 cuts the copper block;

[0075] Step S3: Reverse cutting. When there is a small distance left in the copper block that has not been cut, the cutting blade 7 is moved in the reverse direction. At the same time, the cutting blade 7 equipped with the grinding blade 8 is moved by the moving base 4, so that the cutting blade 7 equipped with the grinding blade 8 moves toward the copper block and rotates to cut the uncut part of the copper block.

[0076] Step S4: grinding, the cutting disc 7 equipped with the grinding disc 8 continues to move toward the copper block, so that the grinding disc 8 grinds the end surface of the copper block cut into two sections to remove burrs;

[0077] Step S5: Return both sets of cutting blades 7 to their original positions, adjust the position of the long copper block, and repeat the above steps to continue cutting the long copper block.

[0078] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
