[0002] Beryllium copper is a copper alloy with beryllium as the main alloying element, possessing numerous excellent properties. These properties make beryllium copper strip widely used in many fields such as electronics, electrical appliances, aerospace, automobiles, and mold making.

[0003] A search revealed that Chinese Patent Publication No. CN204564759U discloses a roller straightening machine, characterized in that: a first lower support is horizontally arranged on the left side of the lower part of the frame, and hydraulic cylinders are respectively arranged at the left and right ends of the bottom of the first lower support; several lower straightening rollers cooperating with the hydraulic cylinders are vertically arranged on the first lower support; a second lower support is horizontally arranged on the right side of the lower part of the frame, and hydraulic cylinders are respectively arranged at the left and right ends of the bottom of the second lower support; several lower straightening rollers cooperating with the hydraulic cylinders are vertically arranged on the second lower support; an upper support is arranged at the upper part of the frame, and hydraulic cylinders are respectively arranged at the left and right ends of the bottom of the upper support.

[0004] The above-mentioned device often uses multiple straightening rollers arranged in an alternating pattern to achieve straightening. However, some parts with strong internal stress cannot be completely eliminated by bending. This part of the material will inevitably affect subsequent use and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a straightening machine for beryllium copper strip rolling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straightening machine for beryllium copper strip rolling, comprising a bottom support frame, a second straightening assembly mounted on the top of the bottom support frame, the second straightening assembly being located on one side of the bottom support frame, the second straightening assembly comprising two guide grooves, both guide grooves being fixedly connected to the top outer wall of the bottom support frame, two rollers being slidably inserted into the interior of each of the two guide grooves, a common receiving plate being fixedly connected to the top outer wall of the four rollers, a second support plate being fixedly connected to the top outer wall of the receiving plate, an electric telescopic rod being fixedly installed on the top outer wall of the second support plate, a pressure plate being fixedly connected to the output end of the electric telescopic rod, a plurality of horizontally arranged electric heating tubes being provided inside the pressure plate, a reset assembly being provided between the receiving plate and the bottom support frame, the reset assembly comprising four extension plates and two second springs.

[0007] It can perform secondary processing on the straightened copper strip, thereby correcting the parts of the copper strip with internal stress to a straight state, which helps to ensure the quality of the copper strip. Activating the electric telescopic rod at the top of the second support plate activates the pressure plate heating device to heat the copper strip. The electric telescopic rod drives the pressure plate to squeeze the copper strip. Under the action of friction, the traction force acts on the second spring through the copper strip and the receiving plate. The second spring is stretched, and the receiving plate moves synchronously with the copper strip, thus continuously applying pressure and heating to the copper strip, allowing it to straighten. Furthermore, the residual internal stress is eliminated under the influence of temperature. When the copper strip moves less than the width of the receiving plate, the electric telescopic rod is controlled to drive the pressure plate upward, the receiving plate is no longer tractioned, and the second spring can drive the receiving plate back to its original position, and then the operation is repeated.

[0008] As a further preferred embodiment of this technical solution, the four extension plates are respectively fixedly connected to the outer walls of the receiving plate and the bottom support frame that are close to each other, and one end of each of the two springs is fixedly connected to the two extension plates on one side of the receiving plate, and the other end is fixedly connected to the two extension plates on the corresponding side of the bottom support frame.

[0009] As a further preferred embodiment of this technical solution, a limiting component is installed on the top of the bottom support frame. The limiting component is located on the other side of the bottom support frame. The limiting component includes a horizontally arranged bidirectional lead screw, which is rotatably connected inside the bottom support frame. A movable seat is threaded to each of the two threads on the outside of the bidirectional lead screw. Two horizontally arranged limiting rods are fixedly connected inside the bottom support frame. The two movable seats are slidably sleeved on the outside of the two limiting rods. A motor is fixedly installed on the outer wall of one end of the bottom support frame, and the output end of the motor is coaxially fixed with one end of the bidirectional lead screw.

[0010] As a further preferred embodiment of this technical solution, each of the two movable seats has two mounting rods slidably inserted inside, and the two mounting rods on one side are fixedly connected to the same movable plate. Each of the four mounting rods is fitted with a spring.

[0011] The rolled copper strip is guided to one end of the bottom support frame. If the position of the copper strip shifts, the movable plate can ensure that the position of the copper strip is more stable. If the width of the copper strip changes, the motor on the side of the bottom support frame is started. The motor output drives the bidirectional lead screw to rotate. The bidirectional lead screw can drive the two moving seats to move towards each other along the two limit rods, which helps to improve the adaptability of the device.

[0012] As a further preferred embodiment of this technical solution, a first straightening component is installed on the top of the bottom support frame. The first straightening component is located in the middle of the bottom support frame. The first straightening component includes a support plate fixedly connected to the bottom support frame. A hydraulic cylinder is fixedly installed on the top outer wall of the support plate. An installation frame is fixedly connected to the output end of the hydraulic cylinder. Several straightening rollers are rotatably connected inside the bottom support frame and inside the installation frame.

[0013] As a further preferred embodiment of this technical solution, four stabilizing rods are fixedly connected to the outside of the bottom support frame, and the mounting frame is slidably sleeved on the outside of the four stabilizing rods.

[0014] As a further preferred embodiment of this technical solution, rubber gaskets are provided on the inner walls of both guide grooves, and the rubber gaskets are in contact with the outer surface of the rollers.

[0015] This utility model provides a straightening machine for beryllium copper strip rolling, which has the following beneficial effects:

[0016] (1) By setting a second straightening component, this utility model can perform secondary processing on the copper strip that has been straightened, so that the part of the copper strip with internal stress can be straightened into a straight state, which is beneficial to ensuring the quality of the copper strip. The electric telescopic rod at the top of the support plate 2 is activated, and the pressure plate heating device is activated to heat the copper strip. The electric telescopic rod drives the pressure plate to squeeze the copper strip. Under the action of friction, the traction force is applied to the spring 2 through the copper strip and the receiving plate. The spring 2 is stretched by the force, and the receiving plate can move synchronously with the copper strip, thereby realizing continuous pressure and heating on the copper strip, so that the copper strip can be transformed into a straight state. Under the influence of temperature, the residual internal stress will also be eliminated. When the copper strip moves less than the width of the receiving plate, the electric telescopic rod is controlled to drive the pressure plate to move up, and the receiving plate is no longer tractioned. The spring 2 can then drive the receiving plate back to its original position, and then the operation is repeated.

[0017] (2) By setting a limiting component, the rolled copper strip is guided to one end of the bottom support frame. If the position of the copper strip is offset, the position of the copper strip can be more stable under the restriction of the movable plate. If the width of the copper strip changes, the motor on the side of the bottom support frame is started. The output end of the motor drives the bidirectional lead screw to rotate.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown, in this embodiment, the straightening machine for beryllium copper strip rolling includes a bottom support frame 1. A second straightening component 4 is installed on the top of the bottom support frame 1. The second straightening component 4 is located on one side of the bottom support frame 1. The second straightening component 4 includes two guide grooves 402. Both guide grooves 402 are fixedly connected to the top outer wall of the bottom support frame 1. Two rollers 403 are slidably inserted into the two guide grooves 402. The top outer wall of the four rollers 403 is fixedly connected to the same receiving plate 401. The top outer wall of the receiving plate 401 is fixedly connected to a second support plate 404. An electric telescopic rod 405 is fixedly installed on the top outer wall of the second support plate 404. A pressure plate 406 is fixedly connected to the output end of the electric telescopic rod 405. Several horizontally arranged electric heating tubes are provided inside the pressure plate 406. A reset component is provided between the receiving plate 401 and the bottom support frame 1. The reset component includes four extension plates 407 and two springs 408.

[0025] Four extension plates 407 are fixedly connected to the outer walls of the receiving plate 401 and the bottom support frame 1, which are close to each other. One end of each of the two springs 408 is fixedly connected to the two extension plates 407 on one side of the receiving plate 401, and the other end is fixedly connected to the two extension plates 407 on the corresponding side of the bottom support frame 1.

[0026] The electric telescopic rod 405 at the top of the support plate 404 is activated, and the heating device of the pressure plate 406 is activated to heat the copper strip. The electric telescopic rod 405 drives the pressure plate 406 to squeeze the copper strip. Under the action of friction, the traction force is applied to the spring 408 through the copper strip and the receiving plate 401. The spring 408 is stretched by the force, and the receiving plate 401 can move synchronously with the copper strip, thereby continuously applying pressure and heating to the copper strip, so that the copper strip can be transformed into a straight state. Under the influence of temperature, the residual internal stress will also be eliminated. When the copper strip moves less than the width of the receiving plate 401, the electric telescopic rod 405 is controlled to drive the pressure plate 406 to move upward, and the receiving plate 401 is no longer tractioned. The spring 408 can then drive the receiving plate 401 back to its original position, and then the operation is repeated.

[0027] like Figure 2 and Figure 4 As shown, a limiting component 3 is installed on the top of the bottom support frame 1. The limiting component 3 is located on the other side of the bottom support frame 1. The limiting component 3 includes a horizontally arranged bidirectional lead screw 301. The bidirectional lead screw 301 is rotatably connected inside the bottom support frame 1. A movable seat 304 is threaded to each of the two threads on the outside of the bidirectional lead screw 301. Two horizontally arranged limiting rods 302 are fixedly connected inside the bottom support frame 1. The two movable seats 304 are slidably sleeved on the outside of the two limiting rods 302. A motor 303 is fixedly installed on the outer wall of one end of the bottom support frame 1. The output end of the motor 303 is coaxially fixed with one end of the bidirectional lead screw 301.

[0028] Two mounting rods 305 are slidably inserted into each of the two movable seats 304. The two mounting rods 305 on one side are fixedly connected to the same movable plate 306. A spring 307 is sleeved on the outside of each of the four mounting rods 305.

[0029] If the copper strip shifts position, the movable plate 306 ensures a more stable position. If the width of the copper strip changes, the motor 303 on the side of the bottom support frame 1 is activated. The output of the motor 303 drives the bidirectional lead screw 301 to rotate, which in turn drives the two movable seats 304 to move towards each other along the two limit rods 302, improving the adaptability of the device. Since the movable plate 306 is connected to the movable seats 304 via the mounting rod 305, this connection method gives the movable plate 306 a certain degree of freedom of movement. When a protrusion appears on the side of the copper strip during the conveying process, the movable plate 306 can adaptably move in the horizontal direction according to the shape and position of the protrusion, ensuring that the copper strip can pass smoothly through the two movable seats 304 even if there is a protrusion on the side, thus ensuring the stability of the device operation.

[0030] like Figure 1As shown in Figure 2, a first straightening component 2 is installed on the top of the bottom support frame 1. The first straightening component 2 is located in the middle of the bottom support frame 1. The first straightening component 2 includes a support plate 201 fixedly connected to the bottom support frame 1. A hydraulic cylinder 202 is fixedly installed on the top outer wall of the support plate 201. An installation frame 203 is fixedly connected to the output end of the hydraulic cylinder 202. Several straightening rollers 204 are rotatably connected inside the bottom support frame 1 and inside the installation frame 203.

[0031] The bottom support frame 1 is externally fixedly connected with four stabilizing rods 205, and the mounting frame 203 is slidably sleeved on the outside of the four stabilizing rods 205, making the movement of the mounting frame 203 more stable.

[0032] The copper strip first passes through the support plate 404 and connects to the external traction structure. After entering the first set of straightening rollers 204, the copper strip is subjected to the pressure of the straightening rollers 204 and begins to undergo elastic and plastic deformation. The amount of pressure from the straightening rollers 204 causes the copper strip to bend to a certain extent, thereby eliminating some of the residual stress in the copper strip. As the copper strip continues to move forward, it passes through subsequent sets of straightening rollers 204 in sequence. Each set of straightening rollers 204 will further bend and straighten the copper strip, gradually improving the straightness of the copper strip. This technology is an existing mature technology and has not been improved, so it will not be described in detail here.

[0033] like Figure 3 As shown, rubber pads are provided on the inner walls of both guide grooves 402, and the rubber pads are in contact with the outer surface of the roller 403, so that the two have a certain damping effect and avoid excessive rebound when the spring 408 retracts.

[0034] This utility model provides a straightening machine for beryllium copper strip rolling, and its specific working principle is as follows:

[0035] During operation, the rolled copper strip is guided to one end of the bottom support frame 1. If the copper strip's position shifts, the movable plate 306 ensures its stability. If the width of the copper strip changes, the motor 303 on the side of the bottom support frame 1 is activated. The output of the motor 303 drives the bidirectional lead screw 301 to rotate, which in turn drives the two movable seats 304 to move towards each other along the two limit rods 302, improving the adaptability of the device. Since the movable plate 306 is connected to the movable seats 304 via the mounting rod 305, this connection method gives the movable plate 306 a certain degree of freedom of movement. When a protrusion appears on the side of the copper strip during transport, the movable plate 306 can adaptably move horizontally according to the shape and position of the protrusion, ensuring that the copper strip can pass smoothly through the two movable seats 304 even with a protrusion, thus ensuring the stability of the device's operation. The copper strip first passes through the support plate 404 and connects to the external traction structure. After entering the first set of straightening rollers 204, the copper strip is subjected to the pressure of the straightening rollers 204 and begins to undergo elastic and plastic deformation. The amount of pressure from the straightening rollers 204 causes the copper strip to bend to a certain extent, thereby eliminating some of the residual stress in the copper strip. As the copper strip continues to move forward, it passes through subsequent sets of straightening rollers 204 in sequence. Each set of straightening rollers 204 will further bend and straighten the copper strip, gradually improving the straightness of the copper strip. Simultaneously, the electric telescopic rod 405 on the top of the support plate 404 is activated, and the heating device of the pressure plate 406 is activated to heat the copper strip. The electric telescopic rod 405 drives the pressure plate 406 to squeeze the copper strip. Under the action of friction, the traction force acts on the spring 408 through the copper strip and the receiving plate 401. The spring 408 is stretched by the force, and the receiving plate 401 can move synchronously with the copper strip, thereby continuously applying pressure and heating to the copper strip, so that the copper strip can be transformed into a straight state. Under the influence of temperature, the residual internal stress will also be eliminated. When the copper strip moves less than the width of the receiving plate 401, the electric telescopic rod 405 is controlled to drive the pressure plate 406 to move upward, and the receiving plate 401 is no longer tractioned. The spring 408 can then drive the receiving plate 401 back to its original position, and then repeat the operation. Since the precision of the receiving plate 401 does not need to be too high, even if the spring 408 swings slightly when it retracts, it will not affect the next operation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
