Abstract
Description
Technical Field
[0001] This invention relates to the field of cylindrical copper material processing technology, specifically to a cylindrical copper material straightening mechanism and a stepped cutting system. Background Technology
[0002] To facilitate storage and transportation, copper materials are typically formed into coils after being melted and shaped. Before further processing of the coiled copper material, it must be threaded into a forming mold. The copper material is driven through the mold continuously by traction force. After being shaped by the mold, it forms a columnar copper material with a preset diameter and surface finish. Finally, it is cut to a fixed length to meet the specifications of subsequent processing.
[0003] In existing technologies, the straightening, sizing, and cutting of coiled copper materials often employs an intermittent operation method: a traction device clamps one end of the copper material and pulls it through a mold to complete straightening and sizing. After the copper material is pulled to a preset length, a cutting device cuts the formed cylindrical copper material. After cutting, the traction device must return to its initial position before the next traction operation can begin. In this processing flow, the traction device is idle during the cutting operation and during its own return stroke, resulting in low equipment utilization and directly leading to low overall copper material processing efficiency. Summary of the Invention

[0010] Preferably, it also includes a limiting roller, which is adapted to the strip groove on the pressure rail.
[0011] A straightening mechanism for columnar copper material includes a laser cutting section and a physical cutting section. The laser cutting section cuts the copper material into copper columns of length L.

[0014] Preferably, the self-rotating assembly includes a rack, a gear, a drive shaft, a transmission component, and a friction roller. The drive shaft and the friction roller are both rotatably connected within the clamping block. The drive shaft and the friction roller are connected by a transmission component.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Please see Figure 1-9 This invention provides a cylindrical copper material straightening mechanism, comprising an unwinding assembly 1, a straightening assembly 2, a straightening mold 3, and a traction unit. The copper material 8 wound on the unwinding assembly 1 passes through the straightening assembly 2 and the straightening mold 3 in sequence and is then connected to the traction unit. The traction unit comprises a traction assembly 4 and a clamping assembly 5. The traction assembly 4 is used to drive the clamping assembly 5 to move, and clamps and pulls the copper material 8 during the movement of the clamping assembly 5. The mechanism also includes a laser cutting unit 9, which is used to cut the copper material 8.
[0029] The unwinding assembly 1 can stably release the coiled copper material 8. The coiled copper material 8 is pre-wound onto the unwinding assembly 1. During operation, the unwinding assembly 1 releases the coiled copper material 8 at a uniform speed by passively rotating.
[0030] Due to the storage characteristics of coiled copper material 8, it has natural bending and residual stress, and cannot be directly put into the straightening die 3 for precise shaping. It needs to be initially straightened by the straightening assembly 2. The straightening assembly 2 consists of multiple sets of straightening rollers that cooperate with each other. They are arranged alternately up and down and left and right. When the copper material 8 passes through the gap between the straightening rollers, the straightening rollers apply a uniform squeezing force to the copper material 8, forcibly correcting the bending deformation of the copper material 8, and at the same time eliminating some residual stress, so that the copper material 8 initially presents a straight state.
[0031] After being preliminarily straightened by the straightening component 2, the copper material 8 enters the straightening mold 3 for precise straightening and sizing. When the copper material 8 is forced through the inner hole of the straightening mold, the inner hole of the mold will generate a uniform force on the surface of the copper material 8, which can further eliminate the residual slight bending of the copper material 8 and achieve complete straightening. In order to achieve the size limit, the diameter of the copper material 8 is precisely controlled within the preset range, which meets the requirements of subsequent deep processing for the dimensional accuracy and surface quality of the copper material 8.
[0032] The traction component 4 can drive the clamping component 5 to move cyclically along a preset trajectory. When the clamping component 5 moves along the straight edge, it first clamps the copper material 8. As it continues to move, it pulls the copper material 8 out of the mold. After reaching a specific position, it is released. The clamping component 5 moves back to the initial position after one cycle and continues to clamp and pull the newly delivered copper material 8. During this process, the continuous output of traction force is achieved.
[0033] The copper material 8 is cut by the laser cutting part 9. The traction force will not be interrupted after the cut, which greatly reduces the ineffective stroke of the traction component 4. Through the alternating work of multiple sets of clamping components 5, while one part is pulling the copper material 8 in the straight edge area, the other part has been reset in another area, realizing continuous traction and completely solving the efficiency bottleneck of traditional intermittent traction, thus improving the straightening efficiency of the copper material 8.
[0034] In an embodiment of the present invention, the traction component 4 includes an annular track 41, displacement seats 42, and a driving member 43. The main body of the annular track 41 is rectangular, with semicircular ends, and the diameter of the semicircles is equal to the length of the shorter side of the rectangle. Several displacement seats 42 are evenly distributed on the annular track 41. The driving member 43 is used to drive each displacement seat 42 to perform cyclic movement along the annular track 41. Clamping components 5 are fixedly installed on each of the displacement seats 42. When the clamping components 5 move along the straight edge of the annular track 41, they can clamp and traction the copper material 8. Specifically, the drive component 43 typically employs a standardized transmission structure such as chain drive, synchronous belt drive, or rack and pinion drive (the specific type is common knowledge to those skilled in the art, and the document does not specify the exact type). This enables synchronous linkage of multiple displacement seats, ensuring that all displacement seats 42 move at the same speed along the circular track 41, thus avoiding uneven tension on the copper material 8 due to speed differences in individual displacement seats 42. The drive component 43 consists of a motor and a chain. The motor output transmits power to all displacement seats 42 through the chain structure, driving each displacement seat 42 to begin cyclical movement along the circular track 41. When the displacement seat 42 drives the clamping assembly 5 into the rectangular straight-side section of the circular track, the displacement direction is perpendicular to the copper material... The conveying directions of 8 are completely consistent. At this time, the clamping component 5 clamps the copper material 8. The uniform movement of the displacement seat 42 is converted into a continuous traction force on the copper material 8 through the clamping component 5. When the displacement seat 42 drives the clamping component 5 to move to the rear section of the circular track, the clamping component 5 automatically releases the cut copper column and it falls. The displacement seat 42 smoothly turns along the semi-circular track, switching from the traction direction to the reset direction, and moves towards the traction starting end of the rectangular straight side. Since multiple displacement seats 42 are evenly distributed, when a group of displacement seats 42 completes the turning and reset and returns to the traction starting end, the previous group of displacement seats 42 has completed the traction of a section of copper material 8 and entered. Through the connection of traction and reset formed by multiple displacement seats 42, continuous cyclic traction is realized.
[0035] Compared to traditional technologies where a single traction device needs to complete three steps—traction, cutting and waiting, and resetting—with the resetting and waiting phases being completely idle, this invention allows traction and resetting to be performed simultaneously through a specific cyclic path, ensuring that multiple displacement seats 42 are always in a traction operation state with rectangular straight edges, thus significantly improving overall processing efficiency.
[0036] In an embodiment of the present invention, the clamping assembly 5 includes a fixing block 51, clamping blocks 52, a pressure rail 53, and rollers 56. The fixing block 51 is fixedly mounted on the displacement seat 42. A pair of clamping blocks 52 are slidably disposed on the fixing block 51. One end of each roller 56 is rotatably connected to a clamping block 52. An inner extrusion groove 55 is formed in the pressure rail 53, which extrudes the roller 56, causing the pair of clamping blocks 52 to close and clamp the copper material 8. A tension member 511 is included, and a pair of tension members 511 are respectively connected to the clamping blocks 52, so that the pair of clamping blocks 52 tend to move away from each other, ensuring that the clamping blocks 52 can unfold smoothly.
[0037] Specifically, when the clamping assembly 5 moves with the displacement seat 42 in the non-traction area of the annular track 41, it disengages from the range of action of the pressure track 53. At this time, the elastic tension of the tension member 511 takes effect, pulling the pair of clamping blocks 52 away from each other along the slide rail of the fixed block 51, maintaining the unfolded state (as shown in the attached figure). Figure 3 As shown in the state, when the displacement seat 42 drives the clamping assembly 5 into the traction area of the straight edge of the annular track, the roller 56 gradually embeds into the inner extrusion groove 55 of the pressure track 53. As the displacement 42 continues to move at a constant speed, the extrusion force of the inner extrusion groove 55 on the roller 56 gradually increases. This extrusion force overcomes the elastic tension of the tension member 511 and pushes the two clamping blocks 52 to move closer to each other along the slide rail until the clamping surface is tightly attached to the surface of the copper material 8, thus completing the stable clamping of the copper material 8.
[0038] When the clamping assembly 5 completes the traction of a section of copper material 8, the laser cutting part 9 cuts the copper material 8. Due to the continuous clamping of the clamping assembly 5, the copper material 8 is still continuously conveyed until it moves with the displacement seat 42 to the semi-circular section at the other end of the circular track. At this point, the roller 56 disengages from the inner extrusion groove 55, the extrusion force disappears, and the elastic tension of the tension member 511 pulls the two clamping blocks 52 away from each other, restoring the unfolded state. The copper column falls off, and the displacement seat 42 at the unfolded opening moves cyclically to the next traction starting position, ready for the next clamping. The clamping and unfolding depend entirely on the movement of the displacement seat, without the need for additional driving components such as motors and cylinders. The structure is simple and adaptable to the cyclic continuous operation requirements of the traction assembly.
[0039] In another embodiment of the present invention, a limiting roller 57 is further included, which is adapted to the strip groove on the pressure rail 53. Specifically, when the clamping assembly 5 moves cyclically along the annular rail 41 with the displacement seat 42, it must always maintain parallelism with the copper material 8 conveying direction; otherwise, the clamping block 52 will not be able to clamp the copper material 8 in the center, or even scratch the surface of the copper material 8. After the limiting roller 57 is embedded in the strip groove of the pressure rail 53, a bidirectional rigid constraint is formed between the roller and the groove wall. As the strip groove extends along the conveying direction of the copper material 8, its inner wall restricts the lateral displacement of the limiting roller 57, thereby forcing the clamping assembly 5 to move only along the length direction of the strip groove, completely eliminating lateral offset or torsion caused by factors such as the resistance of the copper material 8 and uneven extrusion pressure, and ensuring that the pair of clamping blocks 52 are always aligned with the center of the copper material 8.
[0040] In existing technologies, traditional saw blades cut copper pillars in one pass, requiring a large feed rate, which can easily cause localized compression damage to the circumference of the copper pillar. Furthermore, the saw blade edge makes high-intensity contact with the copper material over a large area, leading to tool adhesion and severe wear.
[0041] A stepped cutting system for cylindrical copper material includes a physical cutting section 6 and a laser cutting section 9. The physical cutting section 6 is equipped with four saw blades 65, which cut a single copper column of length L into four segments. The cutting area of one of the saw blades 65 overlaps with the cutting area of the laser cutting section 9. The laser cutting section 9 includes a telescopic component 92 and a laser head 91. The telescopic component 92 drives the laser head 91 to move radially along the copper material 8, thereby cutting the copper material 8 into L-shaped copper columns.
[0042] The laser cutting unit 9 is equipped with a laser head 91 and a telescopic component 92. The telescopic component 92 can drive the laser head 91 to move radially along the copper material 8, thereby realizing the automated action of cutting the copper material 8. By combining the continuous traction rhythm of the ring track 41 and preset the traction speed and laser triggering time, the laser head 91 can quickly cut the continuously passing straightened copper material 8 into copper columns of uniform length L, thus completing the rough cutting and fixed length process.
[0043] In an embodiment of the invention, the physical cutting section 6 includes a frame 61, a linear drive slide rail 62, a horizontal base 63, a rotating shaft 64, a servo motor 66, and a rotation component 59. The linear drive slide rail 62 is mounted on the frame 61, and the horizontal base 63 is mounted on the movable block of the linear drive slide rail 62. Four saw blades 65 are mounted on the rotating shaft 64, which is mounted on the horizontal base 63. The servo motor 66 drives the rotating shaft 64 to rotate. When the copper column moves along the annular track 41 to the area where the physical cutting section 6 is located, the rotation component 59 drives the copper column to rotate.
[0044] Specifically, the linear drive slide rail 62 is mounted on the frame 61, and its movable block is fixedly connected to the horizontal base 63. It can drive the horizontal base 63 to move precisely along the direction perpendicular to the copper column conveying, and adjust the relative position of the saw blade 65 and the copper column. The four saw blades 65 are evenly spaced and fixed on the rotating shaft 64. The servo motor 66 provides stable rotational power to the rotating shaft 64, driving the four saw blades 65 to rotate synchronously at high speed. When the L-shaped copper column after laser cutting moves continuously to the area of the physical cutting section 6 along the annular track 41, the linear drive slide rail 62 pushes the horizontal base 63 to feed, and the four saw blades 65 cut into the copper column simultaneously, cutting a single L-shaped copper column at four positions at one time. The cutting area of one of the saw blades 65 coincides with the cutting area of the laser cutting section 9. While cutting, the saw blade 65 can simultaneously remove the heat-affected zone remaining from the laser cutting, achieving a trimming effect and reducing additional grinding processes.
[0045] In another embodiment of the present invention, the self-rotating component 59 includes a rack 591, a gear 592, a drive shaft 593, a transmission component 594, and a friction roller 595. The drive shaft 593 and the friction roller 595 are both rotatably connected within the clamping block 52. The drive shaft 593 and the friction roller 595 are connected by transmission component 594. The gear 592 is fixedly mounted on the drive shaft 593, and the rack 591 is disposed on the displacement path of the gear 592.
[0046] Specifically, the self-rotating component 59 adopts mechanical linkage automatic triggering to convert the traction motion into the self-rotation power of the copper column, which, together with the four-stage step-by-step cutting, improves the cutting quality.
[0047] The rotating component 59 is integrated into the clamping block 52. The rack 591 is fixedly set in the working area of the physical cutting section 6 and is located on the displacement path of the gear 592. When the clamping component 5 moves the copper column to the cutting area, the gear 592 and the rack 591 mesh precisely. The continuous moving force of the displacement seat 42 is converted into the rotational force of the gear 592, which is transmitted to the friction roller 595 through the transmission shaft 593 and the transmission component 594. The friction roller 595 is in close contact with the surface of the copper column. The rotating friction roller drives the copper column to rotate synchronously through friction. Combined with the four-stage advance of the physical cutting section... The design involves the saw blade feeding 1 / 4 radius each time before resetting. The copper column then moves L / 4 length and rotates 90° before the next cut. This multiple small feeds achieve the cutting of the copper column. The segmented feeds reduce the contact area between the saw blade and the copper material 8, thus reducing the cutting load, preventing tool sticking, and ensuring uniform force on the cutting edge. This significantly reduces local wear and extends the saw blade's lifespan. Due to the rotary cutting, the copper column is subjected to uniform force throughout its circumference. The feed amount of the saw blade 65 per cut is only 1 / 4 of that of a traditional full cut, avoiding damage to the circumference of the copper column from compression. The cut is burr-free and chipped, improving the quality of the circumference of the copper column.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
