Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and in particular to a laser cutting device and process for processing copper cold plates. Background Technology

[0002] Laser cutting equipment for copper cold-rolled plates is mainly used for high-precision forming and processing of copper cold-rolled plates. It uses a laser beam to quickly cut copper materials, ensuring a narrow kerf and a small heat-affected zone to avoid material deformation. Its core function is to absorb horizontal and vertical vibrations during equipment operation through a built-in shock absorption mechanism, keeping the laser head in a stable position and thus ensuring cutting accuracy.

[0003] Traditional cutting devices are widely used in the processing of copper cold plates, but due to limitations in their structure and working principle, they often suffer from some significant problems. Existing devices mostly use general-purpose dampers, which cannot distinguish vibration characteristics in different directions. Vertical vibrations are difficult to absorb effectively through buffering, leading to fluctuations in the distance between the laser focus and the workpiece surface, and unstable laser energy density. Horizontal wobbling causes the laser head to deviate from the preset trajectory, resulting in serrated edges, slag residue, and in severe cases, even arc interruption or burn-through. This lack of directional vibration damping design allows vibrations to be directly transmitted to the laser head, not only reducing cutting accuracy and affecting the dimensional consistency of the processed copper cold plates, but also accelerating the wear of equipment components, hindering improvements in processing quality and production efficiency, and making it difficult to meet the demands of high-precision copper cold plate processing. Summary of the Invention

[0004] Given the problem that existing cutting devices cannot specifically reduce vibrations in different directions, a laser cutting device for processing copper cold plates is proposed.

[0005] Its purpose is to enable the cutting device to mitigate vibrations in different directions and to preset the sensitivity of the response.

[0006] The technical solution of the present invention is a laser cutting device for processing copper cold plates, including a cutting machine body and a shock absorption mechanism disposed on the top of the cutting machine body; The shock absorption mechanism includes a housing on the top of the cutting machine body, a connecting block on the side of the housing away from the cutting machine body, a laser head on the side of the connecting block away from the housing, a circular cavity inside the housing, several telescopic holes arranged in a ring array on the inner wall of the center of the circular cavity, a telescopic rod inside the telescopic holes, a spring on the telescopic rod near the axis of the circular hole, a mass block on the side of several springs away from the telescopic rod, a sealing ring on the side of the telescopic hole away from the mass block, a drive unit on the housing near the telescopic rod, and an adjustment unit on the inner wall of the circular cavity. The cavity is filled with damping fluid, and several springs simultaneously apply force to the mass block, keeping it coaxial with the cavity when no other external force is applied.

[0007] Furthermore, a circular groove is formed on the inner wall of the telescopic hole at the end away from the mass block, and the inner wall of the circular groove is fixedly connected to the sealing ring.

[0008] Furthermore, a circular plate is provided at one end of the telescopic rod near the spring, and the side of the circular plate near the mass block is fixedly connected to the spring.

[0009] Furthermore, the drive unit includes an annular groove formed in the outer casing near the telescopic rod, a plurality of blocks arranged in an annular array on the inner wall of the annular groove, a drive ring disposed inside the annular groove, a worm gear disposed outside the drive ring, and a worm disposed outside the worm gear.

[0010] Furthermore, the inner wall of the drive ring is arranged in a ring array with several drive blocks. The number of drive blocks and stop blocks is the same as that of the telescopic rod. The inclined wall of the drive block near the mass block is slidably connected to the telescopic rod.

[0011] Furthermore, the adjustment unit includes symmetrically opened limiting holes at the top and bottom of the circular cavity, a knob disposed inside the limiting holes, a screw disposed inside the knob, a magnetic sheet disposed at the bottom of the screw, a rubber ring disposed outside the magnetic sheet, the outer side of the rubber ring being slidably connected to the inner wall of the circular cavity, and magnetic rings symmetrically disposed at the top and bottom of the mass block.

[0012] Furthermore, a screw hole is provided at the bottom of the knob, the inner wall of the screw hole is threadedly connected to the screw rod, and a limit block is provided in the middle of the knob, the inner wall of the limit hole is rotatably connected to the limit block.

[0013] Furthermore, shallow grooves are symmetrically provided at the top and bottom of the mass block, the inner wall of the shallow grooves is fixedly connected to the magnetic ring, and a through hole extending to the bottom is provided at the center of the mass block.

[0014] Another objective of this invention is to provide a laser cutting process for processing copper cold plates, the purpose of which is to improve the stability of laser cutting by cooperating with a laser cutting device.

[0015] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting process for processing copper cold plates, comprising the following steps: First, based on the cutting path planning and processing speed requirements of the copper cold plate, adjust the initial state of the damping mechanism. By rotating the knob of the adjustment unit, the screw is moved, thereby adjusting the distance between the magnetic sheet and the magnetic ring, and setting the magnetic constraint strength of the mass block in the vertical direction. Then, the laser cutting device is turned on. When the main body of the cutting machine drives the laser head to move horizontally with acceleration and deceleration or to cut at high speed, the worm gear is rotated to drive the worm wheel to rotate, which in turn drives the drive ring and drive block to rotate. The inclined wall of the drive block is used to press the telescopic rod to precisely adjust the preload of the spring, so as to match the horizontal movement response sensitivity and suppress the horizontal vibration transmitted from the shell to the laser head. Next, during the cutting process, the damping fluid filled in the cavity, together with the spring and magnetic constraint, absorbs the mechanical vibration generated by the main body of the cutting machine in different directions, so that the mass block remains relatively stable, and then the laser head position is ensured through the connecting block.

[0016] Furthermore, when machining complex curved surfaces, the distance between the magnetic sheet and the magnetic ring is increased to reduce the vertical constraint force; when machining thin flat plates, the distance is reduced to increase the vertical constraint force; and during high-speed linear cutting, the spring preload is increased through the worm gear to maintain cutting stability.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a vibration damping mechanism, vibrations from different directions can be reduced, ensuring the cutting quality of the laser head. The device will generate interference from multiple directions during operation, and the vibration damping mechanism can suppress these vibrations. By reducing the shaking generated by the external and internal components, the laser head is kept in a stable state, avoiding processing deviations caused by displacement. The stable operating state ensures that the laser beam accurately acts on the material surface, maintains the consistency of the cutting path, thereby improving the overall processing quality and meeting the needs of high-precision production.

[0018] 2. By setting up a drive unit, the preload applied to the mass block can be adjusted, thereby changing the mass block's response sensitivity to horizontal vibration. The drive unit adjusts the connection state between the mass block and the device by changing the magnitude of the preload. This adjustment mechanism allows the mass block to adapt to horizontal vibration interference of different intensities according to actual working conditions. The optimized connection state changes the response characteristics of the mass block, enabling it to play a damping role in the horizontal direction and maintain the stable operation of the device.

[0019] 3. By setting an adjustment unit, the constraint force of the magnetic sheet on the mass block in the vertical direction can be adjusted, changing the mass block's response sensitivity to vertical vibration. The adjustment unit controls the magnitude of the constraint force generated by the magnetic sheet, thereby restricting the vertical movement of the mass block. By adjusting the constraint force, the inertial characteristics of the mass block in the vertical direction are changed, making it adaptable to vertical vibrations of different frequencies. This adjustment method optimizes the vibration damping performance in the vertical direction, ensuring the stability of the device during vertical movement and guaranteeing processing quality.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-11According to the first embodiment of the present invention, a laser cutting device for processing copper cold plates is provided, including a cutting machine body 1 and a shock-absorbing mechanism 2 installed on the top of the cutting machine body 1. The shock-absorbing mechanism 2 includes a housing 21 fixedly connected to the top of the cutting machine body 1, a connecting block 22 fixedly connected to the side of the housing 21 away from the cutting machine body 1, a laser head 23 fixedly connected to the connecting block 22 away from the housing 21, a circular cavity 24 opened inside the housing 21, and a plurality of telescopic holes 25 in a ring array opened on the inner wall of the middle part of the circular cavity 24, which are slidably connected to the telescopic holes. The telescopic rod 26 inside the 25 is fixedly connected to a spring 27 at one end of the telescopic rod 26 near the axis of the circular hole, a mass block 28 is fixedly connected to the ends of several springs 27 away from the telescopic rod 26, a sealing ring 29 is fixedly connected to the end of the telescopic hole 25 away from the mass block 28, a drive unit is assembled on the outer shell 21 near the telescopic rod 26, and an adjustment unit is assembled on the inner wall of the circular cavity 24; the circular cavity 24 is filled with damping fluid, and several springs 27 simultaneously apply force to the mass block 28, so that it remains coaxial with the circular cavity 24 when it is not subjected to other external forces.

[0024] Specifically, during the cutting operation, the main body 1 of the cutting machine moves the outer casing 21, which in turn moves the connecting block 22 and the laser head 23. As the laser head 23 moves, it emits a laser beam to cut the workpiece. During this movement, the main body 1 vibrates, and this vibration is transmitted to the laser head 23 through the outer casing 21 and the connecting block 22. In this process, the vibration is also transmitted through the outer casing 21 to the telescopic rod 26 inside the telescopic hole 25, which then compresses the spring 27 fixed between the telescopic rod 26 and the mass block 28. At this time, the mass block 28 deviates due to inertia. The mass block 28 moves away from the coaxial state maintained by the spring 27 and moves in the damping fluid in the cavity 24. When the mass block 28 overcomes the viscous resistance of the damping fluid, it converts mechanical kinetic energy into heat energy and dissipates it through the damping fluid. At the same time, the spring 27 deforms under force and generates a restoring force. The inertial force generated by the mass block 28 acts in the opposite direction on the inner wall of the outer shell 21 through the spring 27 and the telescopic rod 26, thereby offsetting part of the external vibration. Finally, the energy dissipation of the damping fluid and the inertial reaction force of the mass block 28 together reduce the vibration amplitude of the outer shell 21, thereby reducing the vibration transmitted to the outer shell 21.

[0025] Reference Figures 4-6 A circular groove is provided on the inner wall of the telescopic hole 25 at the end away from the mass block 28, and the inner wall of the circular groove is fixedly connected to the sealing ring 29.

[0026] Specifically, the sealing ring 29 is fixed in place by the circular groove, and the inner wall of the sealing ring 29 wraps around the telescopic rod 26 and slides with it, so that the damping fluid in the circular cavity 24 cannot enter the annular groove 210 through the telescopic hole 25.

[0027] Reference Figures 3-9A circular plate is provided at one end of the telescopic rod 26 near the spring 27, and the side of the circular plate near the mass block 28 is fixedly connected to the spring 27.

[0028] Specifically, the circular plate provides the connection point between the telescopic rod 26 and the spring 27, which can transmit the force from the telescopic rod 26 and the mass block 28.

[0029] Reference Figures 1-11 The drive unit includes an annular groove 210 opened in the outer shell 21 near the telescopic rod 26, a plurality of annular array of stops 211 fixedly connected to the inner wall of the annular groove 210, a drive ring 212 rotatably connected inside the annular groove 210, a worm gear 213 fixedly connected to the outer side of the drive ring 212, and a worm 214 meshing with the outer side of the worm gear 213.

[0030] Specifically, rotating the worm gear 214 drives the worm wheel 213 to rotate, which in turn drives the drive ring 212 to rotate synchronously. As the drive ring 212 rotates, it compresses the corresponding telescopic rod 26 through several drive blocks, causing the telescopic rod 26 to move closer to the mass block 28. When the telescopic rod 26 moves towards the mass block 28, the energy stored in the spring 27 increases. At this point, stronger vibration is required to make the mass block 28 move relative to the outer shell 21, thereby reducing the sensitivity to vibration response. After rotating a certain angle, the drive ring 212 is blocked by the stop block 211 and cannot continue to rotate. The stop block 211 limits the rotation limit of the drive ring 212. By rotating the drive ring 212 in the opposite direction, the telescopic rod 26 can be moved away from the mass block 28, thereby improving the sensitivity to vibration response.

[0031] Reference Figures 3-8 The inner wall of the drive ring 212 is arranged with a number of drive blocks in a ring array. The number of drive blocks and stop blocks 211 is the same as that of the telescopic rod 26. The inclined wall of the drive block near the mass block 28 is slidably connected to the telescopic rod 26.

[0032] Specifically, the drive block rotates with the drive ring 212. As the drive ring 212 rotates, it presses the telescopic rod 26 with its own inclined surface, thereby adjusting the response sensitivity of the mass block 28 to vibration in the horizontal direction.

[0033] Example 2, refer to Figures 1-11This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adjustment unit includes limiting holes 215 symmetrically opened at the top and bottom of the circular cavity 24, a knob 216 rotatably connected inside the limiting holes 215, a screw 217 threadedly connected inside the knob 216, a magnetic sheet 218 fixedly connected to the bottom of the screw 217, a rubber ring 219 fixedly connected to the outside of the magnetic sheet 218, the outside of the rubber ring 219 being slidably connected to the inner wall of the circular cavity 24, and a magnetic ring 220 symmetrically fixedly connected to the top and bottom of the mass block 28.

[0034] Specifically, when the knob 216 is rotated, it can drive the screw 217 to move up and down through meshing with the screw 217. As the screw 217 moves, it drives the magnetic plate 218 to move, and the magnetic plate 218 drives the rubber ring 219 to move. The outer edge of the rubber ring 219 is tightly fitted with the inner wall of the cavity 24 to prevent the damping fluid from leaking, while ensuring that the magnetic plate 218 and the screw 217 can only move up and down. When the distance between the magnetic plate 218 and the magnetic ring 220 at the top of the mass block 28 increases, the magnetic constraint force on the mass block 28 decreases. At this time, the mass block 28 is more sensitive to vibrations in the vertical direction. Conversely, when the distance between the magnetic plate 218 and the magnetic ring 220 decreases, the magnetic constraint force on the mass block 28 increases. At this time, the mass block 28 is less sensitive to vibrations in the vertical direction.

[0035] Reference Figure 10 and Figure 11 The knob 216 has a screw hole at the bottom, and the inner wall of the screw hole is threaded to the screw rod 217. A limit block is provided in the middle of the knob 216, and the inner wall of the limit hole 215 is rotatably connected to the limit block.

[0036] Specifically, as the knob 216 rotates, it drives the screw 217 to move through the screw hole. By rotating the knob 216 in different directions, it controls the direction of movement of the screw 217, thereby controlling the direction of movement of the corresponding magnetic sheet 218 and rubber ring 219.

[0037] Reference Figure 3 and Figure 8 Shallow grooves are symmetrically provided on the top and bottom of the mass block 28. The inner wall of the shallow groove is fixedly connected to the magnetic ring 220. A through hole extending to the bottom is provided in the center of the mass block 28.

[0038] Specifically, the mass block 28 fixes the magnetic ring 220 through a shallow groove, so that the force between the magnetic ring 220 and the corresponding magnetic sheet 218 can be transmitted to the mass block 28. The rest of the structure is the same as that in Embodiment 1.

[0039] Based on embodiments 1-2, the working principle of this invention is as follows: According to processing requirements, the distance between the magnetic sheet 218 and the magnetic ring 220 is adjusted by rotating the knob 216. Utilizing the characteristic that the magnetic field strength varies at different distances between magnets, the magnitude of the magnetic constraint force on the mass block 28 is changed. In conjunction with the worm gear 213 and worm 214, the drive ring 212 is driven to rotate. The inclined surface of the drive block on the drive ring 212 presses against the telescopic rod 26, adjusting the preload of the spring 27 to adapt to the vibration damping sensitivity in the horizontal and vertical directions. During cutting, external vibration is transmitted through the outer shell 21, causing the mass block 28 to vibrate under forced vibration. The mass block 28 uses its own inertia to generate a reverse force to offset part of the excitation force. At the same time, when moving in the damping fluid, it overcomes the fluid viscous resistance and magnetic constraint, converting mechanical kinetic energy into heat energy to achieve energy dissipation. Through the adjustment of the stiffness of the spring 27 by the drive unit and the synergistic effect of the magnetic support of the adjustment unit, the device can adapt to different working conditions, absorb multi-dimensional composite vibrations, and ensure the dynamic positioning accuracy of the laser head 23.

[0040] Example 3, referring to Figures 1-11 The third embodiment of the present invention provides a laser cutting process for processing copper cold plates, comprising the following steps: S1. First, according to the cutting path planning and processing speed requirements of the copper cold plate, adjust the initial state of the damping mechanism 2. By rotating the knob 216 of the adjustment unit, drive the screw 217 to move, thereby adjusting the distance between the magnetic sheet 218 and the magnetic ring 220, and setting the magnetic constraint strength of the mass block 28 in the vertical direction to adapt to the vertical movement speed of the laser head 23 under different working conditions.

[0041] S2. Then, turn on the laser cutting device. When the main body of the cutting machine 1 drives the laser head 23 to move horizontally with acceleration or deceleration or to cut at high speed, the worm gear 214 drives the worm wheel 213 to rotate, which in turn drives the drive ring 212 and the drive block to rotate. The inclined wall of the drive block presses the telescopic rod 26 to precisely adjust the preload of the spring 27 to match the horizontal movement response sensitivity and suppress the horizontal vibration transmitted from the outer shell 21 to the laser head 23, making the laser cutting more stable.

[0042] S3. Next, during the cutting process, the damping fluid filled in the cavity 24, together with the spring 27 and magnetic constraint, absorbs the mechanical vibration generated in different directions by the main body 1 of the cutting machine, so that the mass block 28 remains relatively stable. Then, the connecting block 22 ensures the accuracy of the position of the laser head 23 and improves the cutting quality.

[0043] S4. When machining complex curved surfaces, the distance between the magnetic sheet 218 and the magnetic ring 220 is increased to reduce the vertical constraint force. When machining thin flat plates, the distance is reduced to increase the vertical constraint force. When cutting at high speed, the preload of the spring 27 is increased through the worm gear 213 and worm 214 to maintain cutting stability and thus increase the yield.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
