[0002] In copper rod processing, the cutting process has always been a key link in the production process. The traditional method of cutting copper rods mainly uses circular saws. However, as the cross-sectional area of ​​the copper rod increases, the traditional method faces problems such as low efficiency and high cost.

[0003] At present, there are many copper rod cutting equipment on the market, such as automatic copper rod cutting machines, CNC copper rod cutting machines, etc. These equipment improve production efficiency and cutting accuracy through automatic feeding, positioning and cutting.

[0004] However, existing copper rod cutting equipment still has some shortcomings when processing copper rods used in hot rolling production. For copper rods with larger cross-sectional areas, traditional circular saw blades require a diameter several times the rod's width to effectively cut them. This increased diameter increases the overall weight of the equipment, requiring reinforcement of the motor and support devices, and resulting in high overall equipment costs.

[0005] Therefore, there is an urgent need for a new copper rod cutting method that can reduce equipment costs and improve production efficiency while ensuring cutting efficiency and accuracy. Summary of the Invention

[0019] a) obtaining the pre-input radius r, cutting length, Y-direction cutting allowance d1, and Z-direction cutting allowance h1 of the circular saw blade;

[0020] b) clamping the copper rod to be cut by the copper rod positioning and measuring unit, and obtaining the width d2 of the copper rod to be cut along the Y direction and the height h2 of the copper rod to be cut in the Z direction;

[0021] c) Calculate the moving distance in the Y direction d3=d2+2d1+2r, the cutting height in the Z direction h3=0.5h2+h1-r, and the cutting height in the Z direction h4=0.5h2-h1+r, and obtain the rectangular sawing route;

[0025] g) When the conveying unit cannot move the copper rod into place, it will stop running if it gets the actual distance of the copper rod that is not in place.

[0026] The technical solution provided by the present invention can have the following beneficial effects:

[0027] 1. The invention adopts a rectangular reciprocating sawing route, so that a circular saw blade with a smaller diameter can be used to saw copper rods with larger cross-sections. A circular saw blade with a diameter slightly larger than the sawing width of the copper rod can complete the sawing of the copper rod. At the same time, the sawing is more efficient and segmented sawing can be completed without frequent resetting. The circular saw blade can efficiently saw copper rods of similar diameter, solving the problem that circular saw blades with smaller diameters have low cutting efficiency and cannot be efficiently used in the production of copper rods with larger cross-sections.

[0028] 2. Circular saw blades with smaller diameters have better sawing stability and higher sawing accuracy. At the same time, the thickness of the circular saw blade is smaller, the saw kerf is narrower, and the sawing consumption is less. When used to saw copper bars with larger cross-sectional area and shorter rod length used in hot rolling production, the sawing copper consumption is reduced and the production cost is significantly reduced.

[0029] 3. The blade guard rotates back and forth to match the cutting direction of the circular saw blade, guiding sawdust and preventing it from scattering. This facilitates collection and protects the circular saw blade, improving safety. The semicircular straight edge of the blade guard is arranged along the Y direction to maximize the cutting range of the circular saw blade.

[0030] 4. The vacuum pump provides negative pressure to guide the sawdust out through the sawdust collection hole on the saw blade guard, further reducing the flying sawdust and at the same time reducing the sawdust to avoid affecting the sawing accuracy.

[0031] The sawdust collecting hole is set at the rear of the cutting direction to facilitate the guidance of sawdust and prevent the sawdust from being rolled into the circular saw blade again, affecting the cutting accuracy.

[0032] The fan blows in room temperature air to create cooling air that cools the circular saw blade, preventing it from overheating and affecting its service life. When using a smaller diameter circular saw blade to cut copper rods, the blade tends to heat up due to the relatively long cutting stroke. Cooling the circular saw blade can maintain and improve cutting efficiency without affecting the service life of the circular saw blade.

[0033] The cooling air blown out of the air cooling port blows through the circular saw blade from the front side and is then discharged from the saw dust collection port on the rear side, making it convenient to collect saw dust with a vacuum pump. The air outlet direction is set opposite to the rotation direction of the saw blade to form turbulence and increase heat exchange efficiency.

[0034] 5. The copper rod is clamped along the Y direction by the first limit block and the first positioning block, and the first distance sensor measures the distance moved by the first positioning block to obtain the maximum width of the copper rod along the Y direction. The second limit block and the second positioning block clamp the copper rod from the Z direction, and the second distance sensor measures the distance moved by the second positioning block to obtain the maximum height of the copper rod along the Z direction. The main control unit calculates the rectangular sawing route of the circular saw blade based on the maximum width and maximum height, thereby achieving efficient automated cutting.

[0035] 6. Through precise calculation and control, the copper rod is automatically positioned and sawed, greatly improving cutting accuracy and efficiency. At the same time, this processing method also has a cyclic cutting function, which can continuously saw the copper rod until the remaining length of the copper rod cannot meet the cutting requirements. The high degree of automation reduces manual intervention and labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following describes embodiments of the present invention in conjunction with the accompanying drawings.

[0046] like Figure 1 and Figure 2As shown, a reciprocating copper rod cutting machine includes a circular saw blade 1, a cutting table 2, a saw blade moving unit 3, a conveying unit 4, a copper rod positioning and measuring unit 5 and a main control unit; the circular saw blade 1 is arranged on one side of the cutting table 2 in the X direction, the conveying unit 4 is arranged on the other side of the cutting table 2 in the X direction, and the length direction of the conveying unit 4 is arranged along the X direction, the supporting surface of the conveying unit 4 is flush with the working table of the cutting table 2, the conveying unit 4 is used to position the copper rod along the X direction, and the conveying unit 4 is also used to convey the copper rod to be cut to the working table of the cutting table 2 along the X direction; the saw blade moving unit 3 is arranged on the Installed on the upper side of the cutting table 2 in the Z direction, the saw blade moving unit 3 is used to drive the circular saw blade 1 to move back and forth along the Y and Z directions; the copper rod positioning and measuring unit 5 is installed on the working surface of the cutting table 2, and the copper rod positioning and measuring unit 5 is used to limit the copper rod to be cut, and the copper rod positioning and measuring unit 5 is also used to measure the copper rod width d2 and height h2, and to send the measurement results to the main control unit; the main control unit is used to control the working state of the copper rod positioning and measuring unit 5, and to control the movement of the saw blade moving unit 3 according to the measurement results, and to control the rotation of the circular saw blade 1.

[0047] The length direction of the copper rod is placed on the conveying unit 4 along the X direction, and the copper rod positioning and measuring unit 5 clamps the copper rod in the Y and Z directions, and measures the width d2 and height h2 of the copper rod according to the clamping distance. The main control unit drives the circular saw blade 1 to rotate, and controls the saw blade moving unit 3 according to the measurement results, driving the circular saw blade 1 to move along the Z direction first, so that the highest point of the circular saw blade 1 is higher than half the height of the copper rod, and the center of the circular saw blade 1 is lower than the lowest point of the copper rod, and then moves close to the copper rod along the Y direction and performs sawing, so as to achieve sawing of the lower half of the copper rod cross section. When the circular saw blade 1 moves beyond the width range of the copper rod, the saw blade moving unit 3 drives the circular saw blade 1 to move upward along the Z direction, so that the lowest point of the circular saw blade 1 is lower than half the height of the copper rod, and the center of the circular saw blade 1 is higher than the highest point of the copper rod, and then moves close to the copper rod along the Y direction and performs sawing, so as to achieve sawing of the upper half of the copper rod cross section, thereby completing the sawing of the entire cross section.

[0048] In the prior art, in order to ensure sawing efficiency, it is usually necessary to use a circular saw blade 1 with a diameter of more than 3 times the width of the copper rod to be sawed to saw the copper rod. However, for the copper rod used in hot rolling production, the cross-sectional area of ​​the copper rod is large, and the circular saw blade 1 that needs to be used is larger in diameter. In order to ensure rigidity, the thickness of the saw blade is increased, and the overall weight is increased. The supporting motor and other stabilizing devices must be reinforced, and the overall equipment cost is high.

[0049] The present invention adopts a rectangular reciprocating sawing route, so that a circular saw blade 1 with a smaller diameter can be used for sawing copper rods with larger cross-sections. A circular saw blade 1 with a diameter slightly larger than the sawing width of the copper rod can be used to complete the sawing of the copper rod. At the same time, the sawing is more efficient and segmented sawing can be completed without frequent resetting, so that the circular saw blade 1 can efficiently saw copper rods of a size similar to its diameter, solving the problem that the circular saw blade 1 with a smaller diameter has low sawing efficiency and cannot be efficiently used in the sawing production of copper rods with larger cross-sections.

[0050] It is worth noting that the circular saw blade 1 with a smaller diameter has better stability and higher sawing accuracy during sawing. At the same time, the circular saw blade 1 has a smaller thickness, the resulting saw gap is narrower, and the sawing consumption is less. When used to saw copper rods with larger cross-sectional area and shorter rod length used in hot rolling production, the sawing copper consumption is reduced and the production cost is significantly reduced.

[0051] Preferably, the saw blade moving unit 3 includes a lifting component, a horizontal moving component and a saw blade connecting frame 37. The lifting component is installed on the cutting table 2, the output end of the lifting component is installed with the horizontal moving component, one end of the saw blade connecting frame 37 is connected to the output end of the horizontal moving component, and the other end of the saw blade connecting frame 37 is rotatably installed with the circular saw blade 1.

[0052] Preferably, the lifting assembly includes a lifting block 31, a column 32, a first screw rod 33 and a first motor (the structure is omitted in the accompanying drawings), the column 32 is installed on the cutting table 2, the first screw rod 33 is rotatably installed on the cutting table 2, the length direction of the column 32 and the first screw rod 33 is set along the Z direction, the lifting block 31 is sleeved on the column 32, the horizontal moving assembly is installed on the lifting block 31, the first motor is used to drive the first screw rod 33 to rotate, and the rotation of the first screw rod 33 is used to drive the lifting block 31 to drive the horizontal moving assembly to move back and forth along the Z direction.

[0053] Preferably, the horizontal moving assembly includes a moving block 34, a crossbeam 35, a second screw rod 36 and a second motor (the structure is omitted in the accompanying drawings), the crossbeam 35 is installed on the lifting block 31, the second screw rod 36 is rotatably installed on the lifting block 31, the length direction of the crossbeam 35 and the second screw rod 36 is set along the Y direction, the moving block 34 is sleeved on the crossbeam 35, one end of the saw blade connecting frame 37 is connected to the moving block 34, the second motor is used to drive the second screw rod 36 to rotate, and the rotation of the second screw rod 36 is used to drive the moving block 34 to drive the saw blade connecting frame 37 and the circular saw blade 1 thereon to reciprocate along the Y direction.

[0054] The saw blade moving unit 3 significantly improves the flexibility and accuracy of the cutting operation. By integrating the lifting component and the horizontal moving component, the circular saw blade 1 can move freely in the Z direction and the Y direction, so that the circular saw blade 1 can be quickly and accurately positioned to accurately cut the copper rod. The lifting component uses the cooperation of the first screw rod 33 and the first motor to ensure that the lifting block 31 and the horizontal moving component it carries can adjust the height smoothly, quickly and accurately along the Z direction, so as to adapt to the cutting requirements of copper rods of different heights and quickly reach the specified cutting height. The horizontal moving component is driven by the second screw rod 36 and the second motor, so that the saw blade connecting frame 37 and the circular saw blade 1 thereon can be flexibly moved along the Y direction to achieve precise positioning and cutting of the copper rod. In addition, the design has a compact structure and is easy to operate, which effectively improves cutting efficiency and operation safety, reduces the complexity and labor intensity of manual operation, and provides strong support for automated cutting operations.

[0057] Preferably, two crossbeams 35 are provided, and the two crossbeams 35 are arranged opposite to each other along the X direction, and the second screw rod 36 is arranged between the two crossbeams 35 .

[0059] Preferably, it also includes a saw blade guard 6 and a guard motor 61. The saw blade guard can be reciprocatingly mounted on the saw blade moving unit 3 and is sleeved on the outside of the circular saw blade 1. The saw blade guard 6 is a semicircular cover body, and the straight edge of the semicircular cover body is arranged along the Y direction. A part of the circular saw blade 1 is arranged in the saw blade guard 6, and the center of the circular saw blade 1 is located in the saw blade guard. The guard motor 61 is used to drive the saw blade guard to rotate around the circular saw blade.

[0060] The blade guard 6 can be rotated back and forth to match the cutting direction of the circular saw blade 1, guiding the direction of sawdust splashing, preventing sawdust from flying everywhere, facilitating sawdust collection, and protecting the circular saw blade 1 to improve safety. The semicircular straight edge of the blade guard 6 is arranged along the Y direction, maximizing the cutting range of the circular saw blade 1.

[0061] In one embodiment, the rectangular cutting route circulates in a clockwise direction. When the circular saw blade 1 saws the lower side of the copper rod cross section along the Y direction, the arc-shaped side of the saw blade guard is located below the circular saw blade 1. When the circular saw blade 1 moves upward along the Z direction, the saw blade guard rotates in a clockwise direction, so that the arc-shaped side of the saw blade guard rotates to the top of the circular saw blade 1. Thereafter, the circular saw blade 1 saws the upper side of the copper rod cross section along the Y direction. When the sawing is completed, when the circular saw blade 1 moves downward along the Z direction, the saw blade guard rotates counterclockwise to reset, so that the arc-shaped side of the saw blade guard is again located below the circular saw blade 1. This reciprocating rotation cooperates with the circular saw blade 1 to complete the cutting of the copper rod.

[0062] Preferably, Figure 3 As shown, it also includes a sawdust collection pipe 71, a filter and a vacuum pump. A sawdust collection hole 601 is provided on the saw blade guard 6. One end of the sawdust collection pipe 71 is connected to the saw blade guard 6 through the sawdust collection hole 601, and the other end of the sawdust collection pipe 71 is connected to the filter, and the filter is connected to the vacuum pump.

[0063] The vacuum pump provides negative pressure to guide the saw dust out through the saw dust collecting hole 601 on the saw blade guard 6, thereby further reducing the flying saw dust and at the same time reducing the saw dust to avoid affecting the sawing accuracy.

[0064] Preferably, the sawdust collecting hole 601 is arranged on the rear side of the saw blade guard 6 along the sawing direction, and the angle a between the center of the sawdust collecting hole 601 and the center of the circular saw blade 1 and the sawing direction is 10~30°.

[0065] The sawdust collecting hole 601 is arranged at the rear of the cutting direction to facilitate guiding the sawdust and prevent the sawdust from being drawn into the circular saw blade 1 again, thereby affecting the cutting accuracy.

[0066] Preferably, it also includes a fan and an air cooling pipe 72. The saw blade guard 6 is provided with an air cooling port 602. One end of the air cooling pipe 72 is connected to the saw blade guard 6 through the air cooling port 602, and the other end of the air cooling pipe 72 is connected to the fan.

[0067] The fan blows in room temperature air to form cooling air to cool the circular saw blade 1, thereby preventing the circular saw blade 1 from overheating and affecting its service life. When using a circular saw blade 1 with a smaller diameter to cut copper rods, the circular saw blade 1 tends to heat up due to the relatively long cutting stroke. Cooling the circular saw blade 1 can maintain and improve cutting efficiency without affecting the service life of the circular saw blade 1.

[0068] Preferably, the air cooling port 602 is provided at the front side of the saw blade guard 6 along the sawing direction, and the air outlet direction of the air cooling port 602 is parallel to the sawing direction.

[0069] The cooling air blown out of the air cooling port 602 blows through the circular saw blade 1 from the front side and is then discharged from the saw dust collection port on the rear side, which is convenient for collecting saw dust in conjunction with the vacuum pump. The air outlet direction is set opposite to the rotation direction of the saw blade to form turbulence and increase the heat exchange efficiency.

[0070] Preferably, the copper rod positioning and measuring unit 5 includes a first limit block 51, a first positioning block 52, a first distance sensor 53, a first oil pump 54, a second limit block 55, a second positioning block 56, a second distance sensor 57 and a second oil pump, the first limit block 51 and the first positioning block 52 are arranged opposite to each other along the Y direction, the first oil pump 54 is used to push the first positioning block 52 to move away from or close to the first limit block 51, the first distance sensor 53 is used to measure the movement distance of the first positioning block 52, the second limit block 55 and the second positioning block 56 are arranged opposite to each other along the Z direction, the second oil pump is used to push the second positioning block 56 to move away from or close to the second limit block 55, and the second distance sensor 57 is used to measure the movement distance of the second positioning block 56;

[0071] The first distance sensor 53 , the first oil pump 54 , the second distance sensor 57 , and the second oil pump are electrically connected to the main control unit.

[0072] In one embodiment, the first limit block 51 is fixed to one side of the working surface of the cutting table 2 along the Y direction, and the second positioning block is movably arranged on the other side of the working surface of the cutting table 2 along the Y direction. The second limit block is embedded and fixed in the cutting table 2 and is flush with the working surface of the cutting table 2. The second positioning block is movably arranged above the second limit block along the Z direction.

[0073] The copper rod is clamped along the Y direction by the first limit block 51 and the first positioning block 52, and the first distance sensor 53 measures the distance moved by the first positioning block 52 to obtain the maximum width of the copper rod along the Y direction. The second limit block 55 and the second positioning block 56 clamp the copper rod from the Z direction, and the second distance sensor 57 measures the distance moved by the second positioning block 56 to obtain the maximum height of the copper rod along the Z direction. The main control unit calculates the rectangular sawing route of the circular saw blade 1 based on the maximum width and maximum height, thereby realizing efficient automatic cutting.

[0075] After the copper rod is placed on the motorized roller 41 of the conveying unit 4 by an external crane, the motorized roller 41 is manually controlled to move the copper rod to the cutting position of the circular saw blade 1. The copper rod distance sensor 8 measures the distance of the copper rod extending from the cutting position along the X direction. The sawing length is manually input. After each section of the copper rod is sawed, the main control unit controls the motorized roller 41 to convey it forward along the X direction according to the sawing length, thereby realizing fully automatic sawing control and improving overall sawing efficiency.

[0076] Preferably, a temperature sensor is further included, which is electrically connected to the main control unit and is used to measure the real-time temperature of the circular saw blade 1. The circular saw blade 1 and the saw blade moving unit 3 are both driven by a servo motor.

[0077] By manually presetting the rotation speed, sawing moving speed and protection temperature of the circular saw blade 1 and measuring the temperature of the circular saw blade 1 in real time, when the temperature of the circular saw blade 1 is higher than the protection temperature, the rotation speed and sawing moving speed of the circular saw blade 1 are synchronously reduced, thereby reducing the frictional heat of the saw blade and the feed amount of each cutting, and extending the service life of the saw blade. When the temperature of the saw blade is lowered, the set rotation speed and sawing moving speed are gradually increased again to improve the sawing efficiency.

[0078] A copper rod sawing method, using the above-mentioned reciprocating copper rod cutting machine, comprises the following steps:

[0079] a) obtaining the pre-input radius r, cutting length, Y-direction cutting allowance d1, and Z-direction cutting allowance h1 of the circular saw blade 1;

[0080] b) clamping the copper rod 9 to be cut by the copper rod positioning and measuring unit 5, and obtaining the width d2 of the copper rod 9 to be cut along the Y direction and the height h2 of the copper rod 9 along the Z direction;

[0081] c) Calculate the moving distance in the Y direction d3=d2+2d1+2r, the cutting height in the Z direction h3=0.5h2+h1-r, and the cutting height in the Z direction h4=0.5h2-h1+r, and get the rectangular sawing route (such as Figure 4 The rectangular dotted box shown is a rectangular sawing route);

[0082] d) Keep the circular saw blade 1 rotating and move it along a rectangular sawing route. Drive the circular saw blade 1 to move first in the Z direction so that the highest point of the circular saw blade 1 is higher than half the height of the copper rod and the center of the circular saw blade 1 is lower than the lowest point of the copper rod. Then, move the circular saw blade 1 closer to the copper rod in the Y direction and perform sawing to achieve sawing of the lower half of the cross section of the copper rod. When the circular saw blade 1 moves beyond the width of the copper rod, the saw blade moving unit 3 drives the circular saw blade 1 to move upward in the Z direction so that the lowest point of the circular saw blade 1 is lower than half the height of the copper rod and the center of the circular saw blade 1 is higher than the highest point of the copper rod. Then, move the circular saw blade 1 closer to the copper rod in the Y direction and perform sawing. Finally, drive the circular saw blade 1 to move in the Z direction to return to the height of the first sawing.

[0083] e) moving the copper rod to be cut forward along the X direction by a cutting length, obtaining the actual distance of the copper rod to be cut along the X direction through the conveying unit 4, and verifying whether the copper rod has been moved in place;

[0084] f) Return to step b) and repeat the cycle;

[0085] g) When the conveying unit 4 cannot move the copper rod into position, it is determined that the actual distance of the copper rod is not in position, and the operation is stopped.

[0086] In a specific embodiment, after the copper rod is manually placed on the conveying unit 4, the conveying unit 4 is manually operated to adjust the position of the copper rod, and the rod head part of the copper rod that needs to be removed is extended out of the cutting table 2 according to the actual situation. After the specified cutting length is input, the reciprocating copper rod cutting machine is started to start fully automatic sawing. The first sawing is to saw off the rod head part of the copper rod, and then automatically adjust and circulate the sawing according to the cutting length. When the copper rod cutting is completed, the remaining copper rod is too short and the conveying unit 4 cannot continue to adjust the distance of the copper rod, the reciprocating copper rod cutting machine automatically stops.

[0087] Through precise calculation and control, the copper rod is automatically positioned and sawed, greatly improving cutting accuracy and efficiency. This processing method also features a cyclical cutting function, continuously sawing the copper rod until the remaining length of the copper rod cannot meet the cutting requirements. This high degree of automation reduces manual intervention and labor intensity.
