Description

Technical Field

[0001] This utility model relates to the technical field of copper bar rolling equipment, and in particular to a copper bar rolling straightening device with an overpressure protection mechanism. Background Technology

[0002] In the copper product processing industry, copper bar rolling is a crucial production step, widely used in electrical equipment, building decoration, and machinery manufacturing. As industries increasingly demand higher quality copper products, the precision and quality of copper bar rolling directly impact the performance and lifespan of subsequent products. High-precision, high-quality rolling straightening equipment not only improves the processing accuracy of copper bars but also reduces scrap rates and increases production efficiency, making it a key technological tool driving the development of the copper product processing industry.

[0003] Traditional copper bar rolling and straightening equipment uses a base as its basic support structure, on which a straightening frame is mounted. The straightening frame is equipped with a drive motor, the motor's output of which is connected to the take-up roller via a transmission belt or gear set to drive the take-up roller's rotation. The straightening frame also features fixed guide rollers, typically located in front of or to the sides of the take-up roller. The number of guide rollers is usually 2-4, their axes parallel to the take-up roller. These guide rollers play a preliminary role in shape correction and guidance during the copper bar rolling process.

[0004] However, during the winding process, as the number of layers of copper strip increases and the thickness increases, the pressure between the guide roller and the copper strip becomes too great and cannot be adjusted in time, which can easily lead to deformation and breakage of the copper strip, or even damage to equipment parts. Utility Model Content

[0005] This invention provides a copper strip winding straightening device with an overpressure protection mechanism, which can solve the problem in the prior art where the pressure between the guide roller and the copper strip is too high and causes damage due to the increase in the number of winding layers and the thickness of the copper strip.

[0006] A copper bar winding straightening device with an overpressure protection mechanism includes a base, a straightening frame, and an overpressure protection mechanism. The straightening frame is fixedly mounted on the base, and a take-up roller is rotatably mounted on the straightening frame. A rotary motor is mounted on the side wall of the straightening frame, and the output end of the rotary motor is connected to the take-up roller. The overpressure protection mechanism is located below the take-up roller. The overpressure protection mechanism includes an abutment roller, a bracket, and a first spring. A protective groove is formed on the side wall of the straightening frame, and the bracket is mounted inside the protective groove. The abutment roller is rotatably mounted on the bracket. The bottom of the bracket is inserted into the straightening frame and connected to the first spring. The bracket passes through the straightening frame and is connected to a control component, which is used to control the distance between the abutment roller and the take-up roller.

[0007] According to one embodiment of the present invention, the control component includes a telescopic motor, a telescopic rod, and a control seat. An ear plate is provided on the outer wall of the correction frame. The telescopic motor is located at the bottom of the ear plate, and its output end is connected to the telescopic rod. The control seat is located at the top of the telescopic rod. A pressure sensor is provided inside the control seat. The bracket extends and retracts through one end of the correction frame and is located inside the control seat.

[0008] According to one embodiment of the present invention, a first sliding groove is provided on the protective groove, and a pressure block is provided on the side wall of the bracket, the pressure block being slidably engaged with the first sliding groove.

[0009] According to one embodiment of the present invention, a connecting block is provided at the bottom of the pressure block, the connecting block is inserted into the control seat, and a second spring is provided inside the control seat. One end of the second spring is connected to the bottom of the connecting block, and the other end is connected to the pressure sensor.

[0010] According to one embodiment of the present invention, the straightening frame is provided with an auxiliary roller, which is used to guide the copper strip rolling process.

[0011] According to one embodiment of the present invention, the side wall of the correction frame is provided with a second sliding groove, an adjustment seat is fixedly provided in the second sliding groove, a third spring is provided inside the adjustment seat, one end of the third spring is connected to the inside of the adjustment seat, and the other end is connected to the semi-circular frame, and the auxiliary roller is rotatably mounted on the semi-circular frame.

[0012] According to one embodiment of the present invention, the axes of the take-up roller and the auxiliary roller are located on the same horizontal plane.

[0013] According to one embodiment of the present invention, the size of the pressure block is adapted to the first sliding groove.

[0014] According to one embodiment of the present invention, the size of the connecting block is adapted to the internal cavity of the control seat.

[0015] According to one embodiment of the present invention, the axes of the take-up roller and the abutment roller are located on the same vertical plane.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In the winding process of this invention, the abutment roller maintains a certain distance from the take-up roller under the support of the first spring. As the number of layers of copper strip increases, the pressure of the take-up roller on the copper strip increases, causing the copper strip to squeeze the abutment roller, thus causing the bracket to move downward against the elastic force of the first spring. The connecting block on the side wall of the bracket moves within the control seat, squeezing the second spring and acting on the pressure sensor. When the pressure reaches a set threshold, the pressure sensor transmits a signal to the telescopic motor, which drives the telescopic rod to retract, causing the control seat to descend. The control seat, through the connecting block, pushes the bracket downward, moving the abutment roller away from the take-up roller, thereby reducing the pressure on the copper strip and achieving overpressure protection.

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0023] like Figures 1 to 3As shown, a copper strip winding straightening device with an overpressure protection mechanism includes a base 1, a straightening frame 2, and an overpressure protection mechanism. The straightening frame 2 is fixedly mounted on the base 1, and a take-up roller 3 is rotatably mounted on the straightening frame 2. A rotary motor 31 is mounted on the side wall of the straightening frame 2, and the output end of the rotary motor 31 is connected to the take-up roller 3. The overpressure protection mechanism is located below the take-up roller 3. The overpressure protection mechanism includes an abutment roller 4, a bracket 22, and a first spring 221. A protective groove 21 is formed on the side wall of the straightening frame 2, and the bracket 22 is disposed in the protective groove 21. The abutment roller 4 is rotatably mounted on the bracket 22. The bottom of the bracket 22 is inserted into the straightening frame 2 and connected to the first spring 221. The bracket 22 passes through the straightening frame 2 and is connected to a control component. The control component is used to control the distance between the abutment roller 4 and the take-up roller 3.

[0024] The control assembly includes a telescopic motor 51, a telescopic rod 52, and a control seat 53. An ear plate 5 is provided on the outer wall of the correction frame 2. The telescopic motor 51 is located at the bottom of the ear plate 5, and its output end is connected to the telescopic rod 52. The control seat 53 is provided at the top of the telescopic rod 52. A pressure sensor 54 is provided inside the control seat 53. The bracket 22 extends and retracts through one end of the correction frame 2 and is located inside the control seat 53.

[0025] Pressure sensor 54 monitors the pressure signal transmitted by connecting block 223 in real time. When the copper strip is compressed, causing bracket 22 to drive connecting block 223 to squeeze the second spring 224 and act on pressure sensor 54, if the pressure exceeds the threshold, pressure sensor 54 feeds back the signal to telescopic motor 51. Telescopic motor 51 drives telescopic rod 52 to extend, driving control seat 53 to rise. Control seat 53 pushes bracket 22 to rise through connecting block 223, causing abutment roller 4 to move away from winding roller 3. When the pressure decreases, telescopic motor 51 runs in reverse, causing abutment roller 4 to reset. This achieves automated and precise control of overpressure protection, allowing for quick and accurate adjustment of the position of abutment roller 4 according to actual pressure conditions, effectively protecting the copper strip from overpressure damage, while reducing manual intervention and improving production efficiency and stability.

[0026] The protective groove 21 is provided with a first sliding groove 23, and the side wall of the bracket 22 is provided with a pressure block 222, which slides in conjunction with the first sliding groove 23. When the bracket 22 moves within the protective groove 21, the pressure block 222 on the side wall slides within the first sliding groove 23. The first sliding groove 23 guides and limits the pressure block 222, ensuring that the bracket 22 can only move vertically up and down, thus ensuring the accuracy of the position adjustment of the abutment roller 4.

[0027] The bottom of the pressure block 222 is provided with a connecting block 223, which is inserted into the control seat 53. The control seat 53 is provided with a second spring 224, one end of which is connected to the bottom of the connecting block 223, and the other end is connected to the pressure sensor 54.

[0028] When the connecting block moves within the control seat 53, it compresses the second spring 224. The second spring 224 transmits the pressure to the pressure sensor 54 and also acts as a buffer to prevent the pressure sensor 54 from being damaged by the instantaneous pressure impact. When the pressure decreases, the second spring 224 pushes the connecting block 223 to reset, so that the abutment roller 4 returns to its initial position.

[0029] The straightening frame 2 is provided with an auxiliary roller 6, which is used to guide the copper strip to be rolled into a circle. The side wall of the straightening frame 2 is provided with a second sliding groove 61, and an adjusting seat 62 is fixedly provided in the second sliding groove 61. A third spring 64 is provided inside the adjusting seat 62. One end of the third spring 64 is connected to the inside of the adjusting seat 62, and the other end is connected to the semi-circular frame 63. The auxiliary roller 6 is rotatably mounted on the semi-circular frame 63.

[0030] When the copper strip is wound into a circle under the traction of the take-up roller 3, the auxiliary roller 6 contacts the copper strip, applies a certain pressure and provides guiding force to help the copper strip maintain the correct winding trajectory. When the shape of the copper strip deviates slightly, the auxiliary roller 6 adaptively adjusts its position under the action of the third spring 64 to correct the copper strip. When the pressure of the copper strip on the auxiliary roller 6 changes, the semi-circular frame 63 moves up and down within the adjusting seat 62 under the elastic force of the third spring 64, driving the auxiliary roller 6 to adjust its position so that the auxiliary roller 6 always maintains good contact and appropriate pressure with the copper strip.

[0031] The axes of the take-up roller 3 and the auxiliary roller 6 are located on the same horizontal plane. This ensures that the copper strip is subjected to uniform force during the winding process and avoids twisting caused by uneven force due to height differences. The axes of the take-up roller 3 and the abutment roller 4 are located on the same vertical plane, so that the abutment roller 4 can act perpendicularly on the copper strip on the take-up roller 3, ensuring the accuracy of pressure monitoring and overpressure protection.

[0032] The size of the pressure block 222 is adapted to the first slide groove 23. This ensures that the pressure block 222 slides tightly within the first slide groove 23, guaranteeing smooth movement and preventing wobbling. The size of the connecting block 223 is adapted to the internal cavity of the control seat 53, ensuring that the connecting block 223 is accurately positioned when moving within the control seat 53, thus ensuring stable pressure transmission.

[0033] The copper strip winding straightening device is based on a base 1, with a straightening frame 2 fixed on the base 1. A take-up roller 3 is rotatably mounted on the straightening frame 2, driven by a rotary motor 31 on the side wall. An overpressure protection mechanism is located below the take-up roller 3 and includes an abutment roller 4, a bracket 22, a first spring 221, and a control assembly. The bracket 22 is placed in a protective groove 21 on the side wall of the straightening frame 2. The abutment roller 4 is rotatably mounted on the bracket 22. The bottom of the bracket 22 is connected to the first spring 221, and the top of the bracket passes through the straightening frame 2 and connects to the control assembly. The control assembly consists of a telescopic motor 51, a telescopic rod 52, and a control seat 53. The telescopic motor 51 is mounted on the bottom of the ear plate 5, the top of the telescopic rod 52 is connected to the control seat 53, and a pressure sensor 54 is installed inside the control seat 53. The top of the bracket 22 is telescopically positioned within the control seat 53. In addition, the straightening frame 2 is equipped with an auxiliary roller 6 to guide the copper strip to be rolled into a circle. The auxiliary roller 6 is installed on an adjustment structure consisting of an adjustment seat 62, a third spring 64, and a semi-circular frame 63. The adjustment seat 62 is fixed in the second slide groove 61. The winding roller 3 is horizontally aligned with the axis of the auxiliary roller 6, and the winding roller 3 is vertically aligned with the axis of the abutment roller 4. The pressure block 222 is adapted to the first slide groove 23, and the connecting block 223 is adapted to the inside of the control seat 53.

[0034] The working principle of this utility model is as follows: The rotary motor 31 is started, driving the take-up roller 3 to rotate. One end of the copper strip is fixed to the take-up roller 3, and the copper strip begins to be rolled into a circle under the traction of the take-up roller 3. The auxiliary roller 6, under the action of the third spring 64, always maintains contact with the copper strip, guiding and assisting in the correction of the copper strip, ensuring the shape and accuracy of the rolled copper strip. During the rolling process, the abutment roller 4 maintains a certain distance from the take-up roller 3 under the support of the first spring 221. As the number of layers of the copper strip increases, the pressure of the take-up roller 3 on the copper strip increases, causing the copper strip to squeeze the abutment roller 4, causing the bracket 22 to move downwards against the elastic force of the first spring 221. The connecting block 223 on the side wall of the bracket 22 moves within the control seat 53, squeezing the second spring 224 and acting on the pressure sensor 54. When the pressure reaches the set threshold, the pressure sensor 54 transmits a signal to the telescopic motor 51. The telescopic motor 51 drives the telescopic rod 52 to retract, which in turn drives the control seat 53 to descend. The control seat 53 pushes the bracket 22 to descend through the connecting block 223, so that the abutting roller 4 moves away from the winding roller 3, thereby reducing the pressure on the copper strip and achieving overpressure protection. When the pressure decreases, the telescopic motor 51 reverses its drive, and the abutting roller 4 moves closer to the winding roller 3 again.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
