Description

Technical Field

[0001] This invention belongs to the field of copper straightening technology, specifically relating to a multi-roller tension straightening device and method for copper processing. Background Technology

[0002] Copper, as a widely used non-ferrous metal material, comes in various forms such as copper rods, copper tubes, copper plates, and copper strips. During the production and processing, it is prone to bending and deformation due to external forces and temperature changes, and straightening devices are needed to restore its straightness and processing accuracy.

[0003] Among the existing copper straightening technologies, the patent technology with authorization announcement number CN218692747U discloses a copper straightening device. It uses a rotating motor to drive the rotating wheel and connecting belt to achieve synchronous operation of the feeding roller and the pressure roller, and completes the integrated operation of copper material conveying and straightening. This solves the problem of time-consuming and labor-intensive manual feeding. However, this device can only be adapted to the straightening of copper materials of a single shape, and the straightening process relies on the squeezing action of the pressure roller, so the tension adjustment effect is limited and the straightening accuracy needs to be improved. The patent technology authorized by announcement number CN218224343U discloses a copper rod straightening device, which uses a motor to drive a rotating wheel to cooperate with an L-shaped fixed cover for straightening, and sets up a cooling water circulation system to achieve cooling and water saving. However, this device is only designed for round workpieces such as copper rods, with a narrow range of applications, and lacks a flexible adaptation mechanism for copper materials of different specifications. At the same time, it does not involve tension straightening technology, making it difficult to meet the requirements for high-precision straightening.

[0004] In summary, the existing technology has the following shortcomings: First, its applicability is limited, mostly designed for single-form copper materials (such as copper rods or general copper materials), and cannot simultaneously meet the straightening needs of copper materials of various shapes such as round tubes, columns, and plates; second, the straightening method is singular, mainly relying on pressure roller extrusion or clamping extrusion, lacking a straightening mechanism of tension stretching and multi-roller synergy, resulting in limited straightening accuracy and stability; third, its adaptability is insufficient, although some devices can adjust the pressure roller spacing, but lack modular adaptation structures for copper materials of different sizes, and the adjustment flexibility and adaptation accuracy need to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-roller tension straightening device and method for copper processing, so as to solve the problems of narrow applicability, limited straightening accuracy and insufficient adaptability in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention is entitled "A Multi-Roller Tension Straightening Device and Method for Copper Material Processing," and the details are as follows: A multi-roller tension straightening device for copper processing includes: The frame serves as the support system for the device; Two straightening mechanisms are symmetrically arranged along the center of the frame. Each mechanism consists of an upper frame, a lower frame, an upper pressure roller, a lower pressure roller, an adjusting component, a positioning component, and an upper pressure block. The upper frame can slide horizontally along the length of the straightening mechanism, and the lower frame can rotate vertically relative to the upper frame. The upper pressure roller is rotatably connected to the upper frame, and the lower pressure roller is rotatably connected to the lower frame. The adjusting component is used to adjust the relative position of the lower and upper pressure rollers. When straightening circular tubular copper materials, the lower and upper pressure rollers are axially aligned. The lower pressure roller and the upper pressure roller are close to each other and can form a through hole for the copper material to pass through laterally, a placement groove for the upper pressure block to be placed vertically, and a positioning hole for the upper pressure block to be positioned by installing positioning components. The first lower half pressure block and the second lower half pressure block are fixed in the through hole by screws. The upper pressure block and the first lower half pressure block and the second lower half pressure block below are combined to form a straightening ring that matches the size of the copper material. When straightening the plate-shaped copper material, the upper pressure roller and the lower pressure roller can be adjusted by adjusting the components to make them staggered so that the copper material can be clamped from top to bottom. The cylinder is fixed to one of the upper frames, and its output end is fixed to the other upper frame. The synchronization mechanism, located at the center of the frame, is used to maintain the synchronicity of the relative movements of the two upper frame bodies.

[0007] Preferably, the frame includes a base, a rail beam is arranged parallel above the base, and support columns are fixed at both ends and the middle of the base. A load-bearing beam for supporting the rail beam is fixed at the top of the support column.

[0008] Preferably, the top of the upper frame is fixed with a slide block that can slide horizontally along the length of the rail beam, and the axial directions of the upper pressure roller and the lower pressure roller are both distributed perpendicular to the movement direction of the upper frame.

[0009] Preferably, the lower frame is hinged to the upper frame at the end away from the lower pressure roller, and the lower frame is provided with a waist-shaped groove, which is distributed along the length of the lower frame.

[0010] Preferably, the adjusting component includes an adjusting rod, the lower end of which is vertically fixed with a limiting rod, the limiting rod being confined within a waist-shaped groove, and the upper outer side of the adjusting rod being slidably connected with a guide sleeve, the guide sleeve being fixed to the bottom of the upper frame, and the top surface of the upper frame being rotatably connected with a rotating sleeve coaxially arranged with the guide sleeve, the rotating sleeve being threadedly connected to the adjusting rod.

[0011] Preferably, the upper pressure roller has a first semicircular hole and a first semi-threaded hole arranged in a cross pattern at one end near the lower pressure roller, and a first semi-mounting groove is formed inside the first semi-threaded hole. The lower pressure roller has a second semicircular hole and a second semi-threaded hole arranged in a cross pattern at one end near the upper pressure roller, and a second semi-mounting groove is formed inside the second semi-threaded hole. The first semicircular hole and the second semicircular hole are aligned to form the through hole. The first semi-threaded hole and the second semi-threaded hole are aligned to form the positioning hole, and an internal thread is formed inside the positioning hole. The first semi-mounting groove and the second semi-mounting groove are aligned to form the placement groove.

[0012] Preferably, the positioning element includes a plug, the bottom of which is fixed with a push rod for pressing against the upper pressure block, the top of which has an internal hexagonal hole, and the outer side of which has an external thread adapted to the internal thread of the positioning hole.

[0013] Preferably, the synchronization mechanism includes a turntable, which is rotatably connected to a load-bearing beam located in the middle position via a rotating shaft. Two symmetrically arranged rotating arms are provided on the outer side of the turntable, and each of the two rotating arms is hinged with a push rod. The two push rods are respectively hinged to two upper frames.

[0014] Based on the above-mentioned apparatus, the present invention also proposes a multi-roller tension straightening method for copper material processing, comprising a method for straightening circular tubular copper materials: Step 1: Select the first lower half pressure block, the second lower half pressure block, and the upper pressure block with inner diameters that match the copper material according to its size; Step 2: Fix the first lower half of the pressure block and the second lower half of the pressure block into the first semicircular hole and the second semicircular hole respectively using screws; Step 3: Adjust the height of the upper pressure roller by adjusting the components to make the upper pressure roller and the lower pressure roller axially coincide. Step 4: Pass the circular tubular copper material through the through hole formed by the alignment of the upper and lower pressure rollers; Step 5: Place the upper pressure block into the placement slot and install the positioning piece on top to tighten the upper pressure block, so that the first lower half pressure block, the second lower half pressure block and the upper pressure block are assembled to form a straightening ring that matches the size of the copper material. In the same way, complete the assembly of the upper pressure roller and the straightening ring on the other side to clamp the copper material. Step six: The cylinder operates, driving the two upper frames to move away from each other. At the same time, the synchronizing mechanism maintains the synchronicity of the relative movement of the two upper frames, and then the circular tubular copper material is straightened by the two straightening mechanisms stretching from the middle to both ends.

[0015] The method also includes methods for straightening plate-shaped copper materials: Step 1: Remove the positioning component and the upper pressure block, and disassemble the first lower half pressure block and the second lower half pressure block; Step 2: Adjust the height of the upper pressure roller by adjusting the components to make the upper pressure roller and the lower pressure roller axially offset; Step 3: Pass the plate-shaped copper material through the gap formed by the upper and lower pressure rollers being staggered vertically; Step four: Adjust the lower pressure roller by adjusting the adjustment components so that the lower pressure roller clamps the plate between the upper pressure rollers. In the same way, complete the clamping assembly of the copper material between the upper and lower pressure rollers on the other side. Step 5: The cylinder operates, driving the two upper frames to move away from each other. At the same time, the synchronizing mechanism maintains the synchronicity of the relative movement of the two upper frames, and then the plate-shaped copper material is straightened by stretching from the middle to both ends through the two straightening mechanisms.

[0016] Compared with related technologies, the multi-roller tension straightening device and method for copper processing provided by the present invention have the following beneficial effects: 1. This invention, through a switchable straightening structure, can achieve precise clamping and straightening of circular tubular copper materials through straightening rings, and can also achieve vertical clamping and straightening of plate-shaped copper materials through the staggered arrangement of upper and lower pressure rollers. It can meet the processing needs of various copper materials without changing equipment, greatly improving the versatility of the device.

[0017] 2. This invention adopts a composite straightening method of multi-roller clamping and tension stretching. Two symmetrically arranged straightening mechanisms are driven by a cylinder to move in opposite directions, applying uniform tension to the copper material. At the same time, the multi-roller clamping effectively eliminates the internal stress of the copper material and improves the straightness accuracy. The synchronization mechanism ensures that the two upper frames move synchronously through the linkage of the turntable, rotating arm and push rod, avoiding uneven force on the copper material and further ensuring the straightening stability.

[0018] 3. On the one hand, the present invention uses modular first lower half pressure block, second lower half pressure block and upper pressure block, which can replace the matching components according to the specific size of the circular tubular copper material to form a precise fitting straightening ring with higher fitting accuracy; on the other hand, by adjusting the threaded transmission structure of the components, the relative position of the upper pressure roller and the lower pressure roller can be precisely adjusted. Whether axially coincident or staggered, highly precise adjustment can be achieved to meet the straightening requirements of copper materials of different thicknesses and diameters.

[0021] The present invention will be further described in detail below with reference to specific embodiments, so that those skilled in the art can understand it.

[0022] Please see Figures 1-9 A multi-roll tension straightening device for copper processing includes a frame 1, two straightening mechanisms 2, a cylinder 3, and a synchronization mechanism 4.

[0023] The frame 1 serves as the support system of the device. The frame 1 includes a base 11, a rail beam 14 is arranged parallel above the base 11, and support columns 12 are fixed at both ends and the middle of the base 11. A load-bearing beam 13 for supporting the rail beam 14 is fixed at the top of the support column 12. Two straightening mechanisms 2 are symmetrically arranged around the center of the frame 1, each consisting of an upper frame 21, a lower frame 22, an upper pressure roller 23, a lower pressure roller 24, an adjusting component 25, a positioning component 26, and an upper pressure block 27. The upper frame 21 can slide horizontally along the length of the straightening mechanism 2, and the lower frame 22 can rotate vertically relative to the upper frame 21. The upper pressure roller 23 is rotatably connected to the upper frame 21, and the lower pressure roller 24 is rotatably connected to the lower frame 22. The adjusting component 25 is used to adjust the relative position of the lower pressure roller 24 and the upper pressure roller 23. When straightening a circular tubular copper material, the lower pressure roller 24 and the upper pressure roller 24 are aligned vertically. 3. The lower pressure roller 24 and the upper pressure roller 23 are close to each other and can form a through hole for the copper material to pass through laterally, a placement groove for the upper pressure block 27 to be placed vertically, and a positioning hole for the positioning component 26 to position the upper pressure block 27. The first lower half pressure block 234 and the second lower half pressure block 244 are fixed in the through hole by screws. The upper pressure block 27 and the first lower half pressure block 234 and the second lower half pressure block 244 below are assembled to form a straightening ring that matches the size of the copper material. When straightening the plate-shaped copper material, the upper pressure roller 23 and the lower pressure roller 24 can be adjusted by adjusting the lower pressure component 25 to make the upper pressure roller 23 and the lower pressure roller 24 staggered to clamp the copper material from top to bottom. The cylinder 3 is fixed to one of the upper frame bodies 21, and its output end is fixed to the other upper frame body 21; The synchronization mechanism 4 is located at the center of the frame 1 and is used to maintain the synchronicity of the relative movement of the two upper frame bodies 21. The synchronization mechanism 4 includes a turntable 41, which is rotatably connected to the load-bearing beam 13 located in the middle position via a rotating shaft 42. Two symmetrically arranged rotating arms 43 are provided on the outer side of the turntable 41, and each of the two rotating arms 43 is hinged with a push rod 44. The two push rods 44 are respectively hinged to the two upper frame bodies 21.

[0024] Furthermore, the top of the upper frame 21 is fixed with a slide block 211 that can slide horizontally along the length of the rail beam 14, and the axial directions of the upper pressure roller 23 and the lower pressure roller 24 are both distributed perpendicular to the movement direction of the upper frame 21.

[0025] Furthermore, the lower frame 22 is hinged to the upper frame 21 at the end away from the lower pressure roller 24, and the lower frame 22 is provided with a waist-shaped sliding groove 221, which is distributed along the length of the lower frame 22.

[0026] Furthermore, the adjusting component 25 includes an adjusting rod 251, with a limiting rod 252 vertically fixed at the lower end of the adjusting rod 251. The limiting rod 252 is confined within the waist-shaped sliding groove 221. A guide sleeve 253 is slidably connected to the outer side of the upper end of the adjusting rod 251. The guide sleeve 253 is fixed to the bottom of the upper frame 21. A rotating sleeve 254, coaxially arranged with the guide sleeve 253, is rotatably connected to the top surface of the upper frame 21. The rotating sleeve 254 is threadedly connected to the adjusting rod 251.

[0027] Furthermore, the upper pressure roller 23 has a first semicircular hole 231 and a first semi-threaded hole 232 arranged in a cross pattern at one end near the lower pressure roller 24. A first semi-mounting groove 233 is formed inside the first semi-threaded hole 232. The lower pressure roller 24 has a second semicircular hole 241 and a second semi-threaded hole 242 arranged in a cross pattern at one end near the upper pressure roller 23. A second semi-mounting groove 243 is formed inside the second semi-threaded hole 242. The first semicircular hole 231 and the second semicircular hole 241 are aligned to form the through hole. The first semi-threaded hole 232 and the second semi-threaded hole 242 are aligned to form the positioning hole, and an internal thread is formed inside the positioning hole. The first semi-mounting groove 233 and the second semi-mounting groove 243 are aligned to form the placement groove.

[0028] Furthermore, the positioning component 26 includes a plug 261, the bottom of which is fixed with a push rod 262 for pressing against the upper pressure block 27, the top of which is provided with an internal hexagonal hole 263, and the outer side of which is provided with an external thread 264 that is adapted to the internal thread of the positioning hole.

[0029] Based on the above-mentioned device, the present invention also proposes a multi-roller tension straightening method for copper processing, which has the following two embodiments: Example 1: Straightening a circular tubular copper material: Step 1: Based on the outer diameter of the circular tubular copper material to be straightened, select the first lower half pressure block 234, the second lower half pressure block 244, and the upper pressure block 27 whose inner diameters are compatible with them; Step 2: Fix the first lower half pressure block 234 into the first semicircular hole 231 of the upper pressure roller 23 with screws, and fix the second lower half pressure block 244 into the second semicircular hole 241 of the lower pressure roller 24. Step 3: Rotate the rotating sleeve 254. Since the rotating sleeve 254 is threadedly connected to the adjusting rod 251 and the adjusting rod 251 is limited by the guide sleeve 253, when the rotating sleeve 254 rotates, it drives the adjusting rod 251 to move up and down. The limiting rod 252 slides in the waist-shaped slide groove 221 and pushes the lower frame 22 to rotate around the hinge point, thereby adjusting the relative position of the upper pressure roller 23 and the lower pressure roller 24 so that the two are axially aligned. Step 4: Pass the circular tubular copper material through the through hole formed by the upper pressure roller 23 and the lower pressure roller 24, ensuring that both ends of the copper material extend to the outside of the two straightening mechanisms 2 respectively; Step 5: Place the upper pressure block 27 into the placement groove formed by the first half placement groove 233 and the second half placement groove 243, so that the upper pressure block 27 fits against the first lower half pressure block 234 and the second lower half pressure block 244. Then screw the positioning member 26 into the positioning hole and press the upper pressure block 27 with the push rod 262 to form a straightening ring that matches the size of the copper material. Complete the assembly of the other side straightening mechanism 2 in the same way to achieve clamping of both ends of the copper material. Step 6: Start cylinder 3. The output end of cylinder 3 pushes the corresponding upper frame 21 to slide along the rail beam 14. At the same time, the turntable 41 of the synchronization mechanism 4 drives the other upper frame 21 to slide in the opposite direction through the rotating arm 43 and the push rod 44, ensuring that the two upper frames 21 move away from the center to both sides synchronously. The two straightening mechanisms 2 apply uniform tension to the copper material, stretching it from the middle to both ends to achieve straightening. After straightening is completed, turn off cylinder 3, remove the positioning part 26 and the upper pressure block 27, and take out the copper material.

[0030] Example 2: Straightening of plate-shaped copper material: Step 1: Remove the positioning part 26 and the upper pressure block 27, and use a screwdriver to remove the screws that fix the first lower half pressure block 234 and the second lower half pressure block 244, and remove them from the corresponding semi-circular holes; Step 2: Rotate the rotating sleeve 254 to drive the adjusting rod 251 to move up and down. Through the limiting rod 252, push the lower frame 22 to rotate, adjust the relative position of the upper pressure roller 23 and the lower pressure roller 24 so that the two are axially offset to form a clamping gap that is suitable for the thickness of the plate-shaped copper material. Step 3: Pass the plate-shaped copper material through the gap between the upper pressure roller 23 and the lower pressure roller 24, ensuring that both ends of the copper material extend to the outside of the two straightening mechanisms 2 respectively; Step 4: Rotate the rotating sleeve 254 again and adjust the height of the lower pressure roller 24 so that the lower pressure roller 24 cooperates with the upper pressure roller 23 to clamp the plate-shaped copper material. Complete the clamping assembly of the copper material of the straightening mechanism 2 on the other side in the same way. Step 5: Start cylinder 3. Cylinder 3 drives the two upper frame bodies 21 to move away synchronously along the rail beam 14. The two straightening mechanisms 2 apply uniform tension to the plate-shaped copper material, stretching it from the middle to both ends to achieve straightening. After straightening is completed, turn off cylinder 3, adjust the adjusting component 25 to loosen the copper material, and then remove it.
