Description

Technical Field

[0001] This invention relates to the field of metal rod processing technology, specifically to a copper rod head cutting machine and method based on clamping. Background Technology

[0002] The ends of calibrated copper bars often have burrs, deformation, or uneven surfaces. If these defects are not addressed promptly, they will affect the quality of subsequent processing and the performance of the finished product. Therefore, using a circular saw head-cutting machine to remove the copper bar ends is a crucial step in ensuring a flat end face, accurate dimensions, and good surface quality. The core component of this type of circular saw head-cutting machine is a high-speed rotating circular saw blade. Combined with a feeding device, a cutting table, and a control system, it enables stable clamping and precise cutting of the copper bar. The feeding device ensures the copper bar enters the cutting area at the correct direction and speed, the cutting table provides stable support, and the control system adjusts the cutting parameters and operating procedures, thereby ensuring efficient and precise cutting. Meanwhile, the cooling system effectively reduces the heat generated during cutting by spraying cutting fluid, preventing material deformation and excessive wear of the saw blade. Specifically, when performing the bar head cutting operation, the copper bar is fed and clamped, and then the high-speed rotating saw blade is started. The feed system pushes it to smoothly cut into the end of the copper bar. Each tooth of the circular saw blade squeezes and shears the metal, continuously peeling the metal into chips and carrying them away by the coolant until the defective end is completely cut off. Then the saw blade retracts, completing one cycle. This shows that existing head-cutting machines mainly use equally spaced feeding rollers to deliver the copper rod head to the circular saw blade. After the copper rod reaches the cutting point, it is positioned by a clamp before the subsequent cutting operation can be carried out. At this time, the equipment is a single-station clamping structure and the copper rod is stationary. This means that the steps of feeding, stopping, clamping, cutting, loosening, and saw blade retraction must be strictly executed during the cutting process. A large amount of time is non-cutting auxiliary time, such as clamping / loosening actions and the saw blade's idle travel. The equipment's capacity is directly limited by the cycle time of this single station and cannot improve the overall utilization rate through parallel operation. Summary of the Invention

[0003] The purpose of this invention is to provide a copper rod head cutting machine and method based on clamping. Multiple copper rods to be cut are placed one by one into a multi-axis rotary clamp assembly and clamped. A sprocket drive assembly drives an axial feed assembly, which in turn moves the multi-axis rotary clamp assembly and the copper rods axially until the rod heads pass through the radial electric clamp and are positioned above the multi-blade rotary cutting assembly. Then, the rotary drive assembly and the multi-axis rotary clamp assembly drive each copper rod to rotate, and a lifting mechanism moves the multi-blade rotary cutting assembly upwards until the rod heads are cut off. This simultaneously completes the cutting of multiple copper rods, thus solving the problems mentioned in the background art.

The output end of the control panel is electrically connected to the input end of the sprocket drive assembly, the multi-blade rotary cutting assembly, the lifting mechanism, the rod-head radial electric clamps, and the rotary drive assembly.

[0005] Preferably, the multi-axis turntable co-rotation fixture assembly includes a bearing housing, a hollow spindle, and a hollow chuck.

The double sprocket front axle and the double sprocket rear axle are connected to the axial feed assembly, and the axial feed assembly drives the long table, bearing seat, hollow spindle, pulley drive structure and hollow chuck to move along the axial direction.

[0009] Preferably, the axial feed assembly includes a crossbeam fixed to the top of the main frame and a front wheel axle and a rear wheel seat fixedly installed at the left and right positions of the top of the crossbeam, respectively. The double sprocket front axle and the double sprocket rear axle pass through the front wheel axle and the rear wheel seat and are rotatably connected. A driven pulley and a driving pulley are fixed on the double sprocket front axle and the double sprocket rear axle, respectively. A multi-wedge belt is installed between the driven pulley and the driving pulley in the same length direction. Two slides are slidably installed on the top of the crossbeam through a rail and a sliding sleeve. The bottom end of the slide is fixedly connected to one end of the multi-wedge belt. A long platform is installed on the top of the two slides. A straight groove notch is provided on one side of the interior of the long platform.

[0010] Preferably, the radial electric clamp for the rod head includes a T-shaped housing fixed on the right outer wall of the main frame, two C-shaped sliding sleeves symmetrically slidably mounted on one side outer wall of the T-shaped housing, and a geared motor installed at the rear position inside the T-shaped housing. The geared motor drives the two C-shaped sliding sleeves to slide towards each other through a linkage structure. The top of each C-shaped sliding sleeve is fixed with an upwardly extending clamping arm. V-shaped notches are provided on the opposite outer walls of the two clamping arms. The input end of the geared motor is electrically connected to the output end of the control panel.

[0011] Preferably, the C-port sliding sleeve has an internal cavity, and the connecting rod structure includes a double round-headed rod hinged inside the cavity and a rotating handle fixed on the output shaft of the geared motor.

[0012] Preferably, the multi-blade rotary cutting assembly includes a U-shaped frame mounted on the drive end of the lifting mechanism, a blade holder welded to the top of the U-shaped frame, and rotating shafts rotatably mounted at equal intervals along the length direction inside the blade holder. One end of the rotating shaft extends through to the outside of the blade holder and is fixed with a circular blade. A protective shell is installed on the outer wall of the blade holder on one side of the circular blade. A second motor is installed on one side of the outer wall of the blade holder. A sprocket constant speed transmission structure for driving the rotating shafts to rotate synchronously is installed on the output shaft of the second motor.

[0013] This invention also provides a method for cutting the head of a copper rod, using the aforementioned clamping-based copper rod head cutting machine, comprising the following steps: S101: The straightened copper rods that need to be processed are loaded one by one onto the various stations of the multi-axis rotary table clamping assembly. After clamping, the operator starts the sprocket drive assembly through the control panel. The sprocket drive assembly serves as the power source, driving the various axial feed assemblies to operate synchronously. The entire multi-axis rotary table clamping assembly and all the copper rods that have been fixed on it move forward smoothly as a whole along the axis of the copper rods until the head of each copper rod to be cut accurately passes through and reaches the predetermined position above the multi-blade rotary cutting assembly. The radial electric clamp of the rod head further clamps and positions the end of the copper rod from the radial direction. S102: After the cutting position of the copper rod head is located, the staff starts the rotary drive assembly, so that each copper rod held by the multi-axis turntable co-rotation fixture assembly rotates at a constant speed around its own axis. S103: The lifting mechanism is activated via the control panel. The lifting mechanism drives the multi-blade rotary cutting assembly to move upward. The multi-blade rotary cutting assembly is equipped with corresponding cutting blades for each copper rod at each station. The continuously rotating copper rod head moves relative to the upward-feeding multi-blade rotary cutting assembly. The sharp blades begin efficient rotary cutting the moment they contact the rod head until the heads of all copper rods are removed simultaneously. S104: After cutting is completed, the lifting mechanism drives the multi-blade rotary cutting assembly to descend and reset, the radial electric clamp of the bar head is released, and the sprocket drive assembly works in the opposite direction, driving the axial feed assembly to drive the entire multi-axis turntable to rotate the clamp assembly and the copper bar that has been cut back to the initial loading position.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The copper rod head cutting machine and method based on clamping is provided with a main frame, a rotary drive assembly, a multi-axis turntable co-rotating clamp assembly, a sprocket drive assembly, an axial feed assembly, a rod head radial electric clamp, a lifting mechanism, and a multi-blade disc rotary cutting assembly, etc., which cooperate with each other. Multiple copper rods for cutting are located in the multi-axis turntable co-rotating clamp assembly and clamped and fixed. The sprocket drive assembly drives the axial feed assembly to work, so that the axial feed assembly drives the multi-axis turntable co-rotating clamp assembly and the copper rods to move axially until the copper rod head passes through. The radial electric clamp for the copper rod head is positioned above the multi-blade rotary cutting assembly. Then, the rotary drive assembly and the multi-axis turntable co-rotating clamp assembly drive each copper rod to rotate. At the same time, the lifting mechanism drives the multi-blade rotary cutting assembly to complete the cutting operation, thus completing the cutting operation of multiple copper rods simultaneously. In one work cycle, through its parallel processing capability, it can simultaneously complete the cutting operation of all copper rods clamped on the multi-axis turntable co-rotating clamp assembly. Theoretically, its output per unit time increases proportionally with the number of workstations, greatly shortening the production cycle and effectively solving the efficiency bottleneck problem in traditional single-station processing. Traditional single-station cutting machines can only process one copper rod at a time. The feeding, positioning, and cutting processes are independent and sequential, resulting in waiting time during feeding or cutting and low overall utilization. In contrast, the multi-axis rotary table clamping assembly can hold multiple copper rods simultaneously. Combined with the sprocket drive assembly and axial feed assembly, multiple copper rods can continuously and synchronously enter the cutting area of ​​the multi-blade rotary cutting assembly. This greatly reduces the waiting and processing time of a single copper rod, enabling batch parallel production. Furthermore, the lifting mechanism and multi-blade rotary cutting assembly can simultaneously rotate and cut multiple copper rods. Combined with the rotation of the copper rods, this ensures the uniformity and stability of the cutting process. The rotation of the copper rods during the cutting process not only contributes to the flatness and smoothness of the cut surface but also reduces the load on individual cutting tools. Secondly, the axial feed assembly drives the multi-axis rotary table co-rotation fixture assembly and the copper rod to move axially, allowing the copper rod to smoothly pass through the radial electric clamp at the rod head and be positioned at the cutting position. During the cutting process, the workpiece is allowed to rotate continuously at a uniform speed. Combined with the upward motion of the multi-blade rotary cutting assembly, this ensures that the saw blade can cut into the material evenly and continuously from all directions around the circumference of the copper rod. This effectively avoids the burrs, micro-tears, or workpiece deformation that may occur due to unidirectional force in traditional fixed cutting, thereby obtaining an extremely smooth, flat, and high-quality end face that is completely perpendicular to the axis of the rod.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1 to 5 The present invention includes a main frame 1, a multi-axis turntable co-rotation fixture assembly 5 for clamping multiple copper rods disposed above the top of the main frame 1, and an axial feed assembly 2 mounted on the top of the main frame 1 and driving the multi-axis turntable co-rotation fixture assembly 5 and the multiple copper rods to move along the axial direction. A long platform 3 is mounted on the drive end of the axial feed assembly 2. The multi-axis turntable co-rotation fixture assembly 5 is fixedly mounted on the top of the long platform 3. A rotary drive assembly 6 for driving the multi-axis turntable co-rotation fixture assembly 5 is mounted on one side of the top of the long platform 3. The main frame 1 is internally equipped with... The main frame 1 is equipped with a sprocket drive assembly 11 that drives the axial feed assembly 2 to operate. Multiple rod head radial electric clamps 7 are installed on the right outer wall of the main frame 1. A lifting mechanism 8 is installed at the right side of the top of the main frame 1, and a multi-blade disc rotary cutting assembly 9 is installed on the drive end of the lifting mechanism 8. A control panel 10 is installed on one side of the top of the main frame 1. The output end of the control panel 10 is electrically connected to the input end of the sprocket drive assembly 11, the multi-blade disc rotary cutting assembly 9, the lifting mechanism 8, the rod head radial electric clamps 7, and the rotary drive assembly 6, respectively. This embodiment provides a method for cutting the head of a copper rod, using the aforementioned clamping-based copper rod head cutting machine, and includes the following steps: S101: The straightened copper rods that need to be processed are loaded one by one onto the various stations of the multi-axis rotary table clamping assembly 5. After clamping, the operator starts the sprocket drive assembly 11 through the control panel 10. The sprocket drive assembly 11 serves as a power source to drive the various axial feed assemblies 2 to operate synchronously. The entire multi-axis rotary table clamping assembly 5 and all the copper rods that have been fixed on it move forward smoothly along the axis of the copper rods as a whole until the part of each copper rod to be cut accurately passes through and reaches the predetermined position above the multi-blade rotary cutting assembly 9. The end of the copper rod is further clamped and positioned from the radial direction by the rod head radial electric clamp 7. S102: After the cutting position of the copper rod head is located, the staff starts the rotary drive assembly 6, so that each copper rod held by the multi-axis turntable co-rotation fixture assembly 5 rotates at a constant speed around its own axis. S103: The lifting mechanism 8 is activated via the control panel 10. The lifting mechanism 8 drives the multi-blade rotary cutting assembly 9 to move upward. The multi-blade rotary cutting assembly 9 is equipped with corresponding cutting blades for each copper rod at each station. The continuously rotating copper rod head moves relative to the upward-feeding multi-blade rotary cutting assembly 9. The sharp blades begin to perform efficient rotary cutting the moment they contact the rod head, until the heads of all copper rods are cut off simultaneously. S104: After the cutting is completed, the lifting mechanism 8 drives the multi-blade rotary cutting assembly 9 to descend and reset, the rod head radial electric clamp 7 is released, and the sprocket drive assembly 11 works in the opposite direction, driving the axial feed assembly 2 to drive the entire multi-axis turntable to rotate the clamp assembly 5 and the copper rod that has been cut back to the initial loading position.

[0019] Example 2, based on Example 1, is... Figure 6 , Figure 7 and Figure 8 The multi-axis turntable co-rotation fixture assembly 5 includes a bearing housing 501, a hollow spindle 502, and a hollow chuck 504. The bearing housing 501 is fixed to one side of the top of the long platform 3. The hollow spindle 502 is rotatably mounted in the bearing housing 501 through a roller bearing. The hollow chuck 504 is fixed to the outer circumferential surface of the hollow spindle 502. A pulley transmission structure 503 for driving the rotation of the other hollow spindles 502 is installed at the end of the hollow spindle 502 away from the hollow chuck 504. When clamping multiple copper rod workpieces using the multi-axis turntable co-rotation fixture assembly 5, the copper rod is inserted into the hollow spindle 502 along the central axis of the hollow chuck 504 until the end of the copper rod to be cut passes through to the rod head radial electric clamp 7. Then, the operator operates the hollow chuck 504 to firmly fix the copper rod, preventing the copper rod from sliding or vibrating during the cutting process and ensuring the stability of the cutting. At least one elastic tube support structure 4 is installed at the top of the long platform 3. The elastic tube support structure 4 includes a T-shaped rod, a helical spring, and a V-shaped seat. There are four T-shaped rods, which are fixed at the top of the long platform 3 in a rectangular distribution. The helical spring is fitted on the T-shaped rod. The V-shaped seat is slidably installed on the four T-shaped rods, and the lower surface of the V-shaped seat is in contact with the upper end of the helical spring. Ball bearings are embedded on the left and right slopes at the top of the V-shaped seat. The elastic tube support structure 4 is used to support the copper rod body upward and assist the copper rod in its subsequent rotation. The rotary drive assembly 6 includes a housing 601 fixed to one side of the top of the long platform 3, a first motor 602 mounted on the inclined outer wall of the housing 601 away from the hollow chuck 504, and a gear reduction transmission structure 603 mounted on the output shaft end of the first motor 602. The first motor 602 drives one of the hollow spindles 502 to rotate through the gear reduction transmission structure 603. The input end of the first motor 602 is electrically connected to the output end of the control panel 10. After multiple copper rods are installed into the multi-axis turntable co-rotation fixture assembly 5, the operator turns on the first motor 602 through the control panel 10. In operation, the output shaft of the first motor 602 drives one of the hollow spindles 502, the hollow chuck 504, and the clamped copper rod in the multi-axis rotary table co-rotation fixture assembly 5 to rotate via the gear reduction transmission structure 603. The other hollow spindles 502 and the clamped copper rods will rotate together under the drive of the pulley transmission structure 503. By making the clamped copper rods rotate around their own axes, the unevenness and burrs caused by unilateral cutting are avoided, the cutting quality and surface finish are improved, and the rotation can also distribute the cutting load of the multi-blade rotary cutting assembly 9, extend the tool life and reduce equipment wear. The sprocket drive assembly 11 includes a double sprocket front axle 1102 and a double sprocket rear axle 1103 rotatably mounted inside the main frame 1 at left and right positions. A servo motor 1101 is mounted on the inner wall of one side of the main frame 1. The output shaft of the servo motor 1101 extends to the outside of the main frame 1 and is equipped with a chain unit 1104 for driving the double sprocket front axle 1102 and the double sprocket rear axle 1103 to rotate. The input end of the servo motor 1101 is electrically connected to the output end of the control panel 10. The double sprocket front axle 1102 and the double sprocket rear axle 1103 are connected to the axial feed assembly 2. The servo motor 1101 moves along the axial direction via the axial feed assembly 2, driving the long table 3, bearing housing 501, hollow spindle 502, pulley drive structure 503, and hollow chuck 504. When the sprocket drive assembly 11 and axial feed assembly 2 drive the multi-axis turntable co-rotation fixture assembly 5 and the clamped copper rods to move along the axial direction, the servo motor 1101 works according to the direction, speed, angle, and response time set by the control panel 10. The servo motor 1101 drives the double sprocket rear axle 1103 and double sprocket front axle 1102 to rotate via the chain unit 1104. The axial feed assembly 2 includes a crossbeam 201 fixed to the top of the main frame 1, and a front wheel axle 202 and a rear wheel seat 203 fixedly installed at the left and right positions of the top of the crossbeam 201, respectively. The double sprocket front axle 1102 and the double sprocket rear axle 1103 pass through the front wheel axle 202 and the rear wheel seat 203 and are rotatably connected. The double sprocket front axle 1102 and the double sprocket rear axle 1103 are respectively fixed with a driven pulley 205 and a driving pulley 206. A multi-wedge belt 207 is installed between the driven pulley 205 and the driving pulley 206 in the same length direction. Two slides 204 are slidably installed at the top of the crossbeam 201 through a rail and a sliding sleeve. The bottom end of the slide 204 is fixedly connected to one end of the multi-wedge belt 207. The long platform 3 is installed at the top of the two slides 204. A straight groove notch 301 is provided on one side of the interior of the long platform 3. Due to the straight groove notch 301, the long platform 3 will not collide with the rear axle 1103 of the double sprocket when it moves linearly in the axial direction. Driven pulley 205 and drive pulley 206 rotate together with the double sprocket front axle 1102 and double sprocket rear axle 1103. They also use multi-wedge belt 207 to drive slide table 204, long table 3, and multi-axis turntable to rotate. The clamp assembly 5 moves along the length of crossbeam 201 until the copper rod head passes through the rod head radial electric clamp 7 and is located above the cutter of multi-blade disc rotary cutting assembly 9. This ensures that the copper rod smoothly transitions from the feeding position to the cutting position.

[0020] Example 3, based on Example 2, by Figure 9 , Figure 10 , Figure 11 and Figure 12 The radial electric clamp 7 for the rod head includes a T-shaped housing 701 fixed on the outer wall of the right side of the main frame 1, two C-shaped sliding sleeves 702 symmetrically slidably mounted on one side of the outer wall of the T-shaped housing 701, and a geared motor 704 installed at the rear position inside the T-shaped housing 701. The geared motor 704 drives the two C-shaped sliding sleeves 702 to slide towards each other through a linkage structure. The input end of the geared motor 704 is electrically connected to the output end of the control panel 10. The top of the C-shaped sliding sleeve 702 is fixed with an upwardly extending clamping arm 703. V-shaped notches 7031 are provided on the opposite side outer walls of the two clamping arms 703 to improve the pipe diameter adaptability of the clamping arms 703. The C-sleeve 702 has an internal cavity 7021. The connecting rod structure includes a double round-headed rod 7022 hinged inside the cavity 7021 and a handle 705 fixed to the output shaft of the geared motor 704. One end of the handle 705 is hinged to one end of the double round-headed rod 7022. A decorative cover 7023 is installed on the outer wall of the C-sleeve 702 away from the T-shaped housing 701. After the copper rod smoothly transitions from the feeding position to the cutting position, the operator turns on the geared motor 702 in the radial electric clamp 7 of the rod head through the control panel 10. When operation begins, the output shaft of the geared motor 704 drives the rotating handle 705 to rotate. During rotation, the rotating handle 705 drives the two C-shaped sliding sleeves 702 to move towards each other via the double round-headed rod 7022. That is, the two C-shaped sliding sleeves 702 and the two clamping arms 703 move closer to each other until the copper rod is clamped and fixed by the clamping arms 703. At this time, radial clamping can effectively prevent the copper rod from radially shifting or swaying during the cutting process, further enhancing the stability and safety during cutting. Moreover, the electric drive can respond quickly, realize automatic clamping and loosening, and improve operating efficiency.

[0021] Example 4, based on Example 3, by Figure 13 and Figure 14 It is provided that the lifting mechanism 8 can use a hydraulic cylinder as the driving component. The hydraulic cylinder has strong pushing and pulling force and load-bearing capacity, which can stably drive the multi-blade rotary cutting assembly to complete the vertical lifting action, ensuring that the blade can smoothly and accurately contact the copper rod head during the cutting process, and achieve a high-quality cutting effect. The multi-blade rotary cutting assembly 9 includes a U-shaped frame 901 mounted on the drive end of the lifting mechanism 8, a blade holder 902 welded to the top of the U-shaped frame 901, and rotating shafts 903 rotatably mounted at equal intervals along the length direction inside the blade holder 902. One end of the rotating shaft 903 extends through to the outside of the blade holder 902 and is fixed with a circular blade 904. A protective shell 906 is installed on the outer wall of the blade holder 902 on one side of the circular blade 904. A second motor 905 is installed on one side of the outer wall of the blade holder 902. A drive shaft for driving... The sprocket constant speed transmission structure 907 drives the synchronous rotation of each rotating shaft 903. The driving end of the lifting mechanism 8 drives the U-shaped frame 901, the cutter head frame 902 and each circular blade 904 to move upward. During the upward movement, the second motor 905, under the control of the control panel 10, drives each rotating shaft 903 and the circular blade 904 to rotate synchronously through the sprocket constant speed transmission structure 907. Each circular blade 904 corresponds to a clamped and continuously rotating copper rod. At this time, the circular blade 904 cuts the head of the copper rod in a high-speed rotation mode, and the cutting surface is smooth and the cutting force is evenly distributed.

[0022] In this embodiment, the straightened copper rods that need to be processed are first loaded one by one onto the various stations of the multi-axis rotary table jig assembly 5. The multi-axis rotary table jig assembly 5 is operated to firmly clamp each copper rod to ensure that they will not loosen or shift during subsequent vigorous movement and processing. After clamping, the operator starts the sprocket drive assembly 11 through the control panel 10. The sprocket drive assembly 11 serves as a power source to drive the various axial feed assemblies 2 to operate synchronously. The entire multi-axis rotary table jig assembly 5 and all the copper rods that have been fixed on it move forward smoothly along the axis of the copper rods as a whole. The feeding process continues until the part of each copper rod to be cut has accurately passed through and reached the predetermined position above the multi-blade rotary cutting assembly 9. Then, the control panel 10 controls the radial electric clamp 7 of the rod head to move to further clamp and position the end of the copper rod from the radial direction to eliminate any possible slight sway at the rod head. After the copper rod head is positioned for cutting, the operator starts the rotary drive assembly 6, causing each copper rod held by the multi-axis turntable co-rotation fixture assembly 5 to rotate uniformly around its own axis. Simultaneously, the lifting mechanism 8 is activated via the control panel 10, which drives the multi-blade rotary cutting assembly 9 to move upwards. The multi-blade rotary cutting assembly 9 is equipped with corresponding cutting blades for each copper rod at each station. The continuously rotating copper rod head moves relative to the upward-feeding multi-blade rotary cutting assembly 9. The sharp blades begin efficient rotary cutting the instant they contact the rod head. Because the copper rod is continuously rotating, the cutting force is evenly distributed across the entire circumference of the rod head. This makes the cutting process smoother and effectively avoids burrs and deformation that are easily generated by unidirectional cutting. As the multi-blade rotary cutting assembly 9 continues to rise, the heads of all copper bars are cleanly and simultaneously removed, thus completing the head-cutting operation of the entire batch of copper bars in one go and at the same time. After the cutting is completed, the lifting mechanism 8 drives the multi-blade rotary cutting assembly 9 to descend and reset, the radial electric clamp 7 of the bar head is released, and the sprocket drive assembly 11 works in the opposite direction, driving the axial feed assembly 2 to drive the entire multi-axis turntable to rotate the clamp assembly 5 and the copper bars that have been head-cut back to the initial loading position. Finally, the workers remove the entire batch of processed copper bars and prepare for the loading of the next batch of copper bars.
