Description

Technical Field

[0001] The present application relates to the technical field of nickel strip recycling equipment, and in particular to a nickel strip turner. Background Art

[0002] The wire drawing machine is a device for continuously drawing wires. Among the processing steps of the wire drawing machine, there is an annealing step, which mainly involves the wire drawing machine heat treating the drawn wire to eliminate internal stress, stabilize the size, and improve the strength and ductility of the wire.

[0003] Nickel strips are needed in the annealing step of the wire drawing machine. The main purpose of using nickel strips is to enhance the stability of the annealing process and the quality of the wire, while extending the service life of the equipment.

[0004] At present, the nickel strip used inside the wire drawing machine is a nickel strip ring bent into an arc, and there is a gap between the two ends of the nickel strip ring. Generally, the working surface of the nickel strip ring is the inner ring surface of the nickel strip ring. This means that after the working surface of the nickel strip ring is used, the nickel strip ring will be scrapped, which leads to a high frequency of replacement of the nickel strip ring and causes more waste of nickel strip. Utility Model Content

[0005] The present application provides a nickel band turner, the purpose of which is to turn over a used nickel band ring, thereby converting the inner ring surface of the nickel band ring into an outer ring surface, and at the same time converting the outer ring surface of the nickel band ring into an inner ring surface, so that the inner ring surface of the turned nickel band ring can continue to be used, thereby reducing the replacement frequency of the nickel band and reducing the waste of the nickel band.

[0006] The nickel strip turner provided in the present application adopts the following technical solution:

[0007] A nickel strip turner, comprising: an installation box, a first roller, a second roller and a rounding roller are arranged on one side of the installation box, the first roller, the second roller and the rounding roller are arranged in parallel in their axial directions, and the rounding roller is located between the first roller and the second roller;

[0008] The first roller, the second roller and the rounding roller are all rotatably connected to the installation box, and the rounding roller is coaxially connected to a conveying drive member for driving the rounding roller to rotate;

[0009] The rounding roller is slidably connected to the installation box, and the sliding direction is perpendicular to the spacing direction of the first roller and the second roller. The rounding roller is provided with an adjusting driving member for driving the rounding roller to slide in the installation box.

[0010] By adopting the above technical solution, firstly, the first roller, the second roller and the rounding roller are arranged in coordination. After the nickel strip is fed into the flipper, the nickel strip passes through the first roller, the rounding roller and the second roller in sequence. When the conveying driving member drives the rounding roller to rotate, the nickel strip is conveyed out of the flipper as the rounding roller rotates. By selecting the clockwise rotation or counterclockwise rotation of the rounding roller, the nickel strip can be reciprocated in the flipper.

[0011] Secondly, since the rounding roller is slidably connected to the mounting box and the sliding direction is perpendicular to the spacing direction between the first roller and the second roller, the position of the rounding roller can be adjusted by adjusting the driving member. Therefore, after the nickel strip passes through the first roller, the rounding roller and the second roller, adjusting the position of the rounding roller can change the deformation of the nickel strip.

[0012] By coordinating the conveying drive and the adjusting drive, when the nickel band ring reciprocates in the flipper, the deformation of the nickel band can be gradually adjusted, so that the curvature of the nickel band ring can be gradually eliminated and transformed into a long straight nickel band. After the nickel band is flipped and reloaded into the flipper, the curvature of the nickel band will gradually recover. However, at this time, the inner ring surface of the new nickel band ring is the outer ring surface of the previous nickel band ring, so the nickel band can be reused. This can reduce the replacement frequency of the nickel band and reduce the waste of the nickel band.

[0013] Optionally, a mounting plate is provided on the mounting box, and corresponding side walls of the mounting box are extended from both sides of the mounting plate in the length direction, and mounting holes are penetrated through both ends of the mounting plate in the length direction.

[0017] Optionally, the conveying drive member includes a driving handle, and one end of the driving handle is coaxially connected to the rounding roller.

[0018] By adopting the above technical solution, the driving handle is coaxially arranged with the rounding roller, and the rounding roller can be manually driven to rotate.

[0019] Optionally, the driving handle includes a connecting rod, an extension rod and a handle rod, the two ends of the extension rod are respectively connected to the connecting rod and the handle rod, and the handle rod and the connecting rod are located on opposite sides of the extension rod, the handle rod is arranged parallel to the connecting rod, and the connecting rod is coaxially connected to the rolling roller.

[0020] By adopting the above technical solution, the connecting rod in the driving handle can be connected to the rounding roller, thereby realizing the driving of the rounding roller, and the extension rod can extend the distance between the connecting rod and the handle rod, so that the staff can save more effort when driving the rounding roller to rotate through the driving handle.

[0021] Optionally, the adjusting drive member includes a driving screw, the axial direction of the driving screw is perpendicular to the spacing direction of the first roller and the second roller, and the driving screw is connected to the mounting box by a thread, one end of the driving screw extends to the outside of the mounting box, and the other end is provided with a connecting member, the connecting member is rotatably connected to the driving screw, and the connecting member is rotatably connected to the rounding roller along the circumference of the rounding roller.

[0022] By adopting the above technical solution, the driving screw rod is rotatably connected to the mounting box, so when the driving screw rod is twisted, the driving screw rod will move along its own axial direction.

[0023] One end of the driving screw is provided with a connecting piece, and the connecting piece is rotatably connected to the driving screw, which enables the driving screw to be twisted to realize the movement of the driving screw along its own axial direction. At the same time, since the connecting piece rotates with the rolling roller along the circumference of the rolling roller, the rotation of the rolling roller itself will not be affected.

[0024] Therefore, the coordinated arrangement of the driving screw and the connecting member can achieve the adjustment of the position of the rounding roller by the adjusting driving member, while not affecting the driving of the rounding roller by the conveying driving member.

[0025] Optionally, one end of the driving screw away from the rounding roller is coaxially connected to a driving handwheel.

The first roller 21 and the second roller 22 are arranged parallel to each other, and the axial directions of the first roller 21 and the second roller 22 are arranged along the thickness direction of the installation box 11. The ends of the first roller 21 and the second roller 22 close to the installation box 11 are rotatably connected to the installation box 11.

[0056] Specifically, the first roller 21 and the second roller 22 have the same structure, and the first roller 21 includes a fixed column 211 and a support bearing 212. The fixed column 211 is axially arranged along the thickness direction of the installation box 11, one end of the fixed column 211 is fixedly connected to the side wall of the installation box 11, and the support bearing 212 is sleeved on the outside of the fixed column 211. Therefore, the first roller 21 and the second roller 22 have a guiding function and a supporting function.

[0057] Reference Figure 1 A rounding roller 23 is arranged between the first roller 21 and the second roller 22, and the rounding roller 23 is arranged axially along the thickness direction of the installation box 11. One end of the rounding roller 23 is rotatably connected to the installation box 11, and the rounding roller 23 is slidably connected to the installation box 11 along the length direction of the installation box 11.

[0058] Reference Figure 1 and Figure 2 , both sides of the installation box 11 in the thickness direction are penetrated with adjustment long holes 111, and the length direction of the adjustment long holes 111 is set along the length direction of the installation box 11. A driving column 5 is set in the installation box 11, and the driving column 5 is axially set along the thickness direction of the installation box 11, and the two ends of the driving column 5 are respectively plugged and matched with the corresponding adjustment long holes 111, and the end of the driving column 5 facing the rounding roller 23 is coaxially connected to the rounding roller 23, and the driving column 5 is slidably connected to the inner wall of the adjustment long hole 111 along the length direction of the adjustment long hole 111. Therefore, the setting of the driving column 5 realizes the connection relationship between the rounding roller 23 and the installation box 11.

[0059] Reference Figure 1 and Figure 2 One end of the driving column 5 away from the rounding roller 23 is coaxially connected to the conveying driving member 3.

[0060] Reference Figure 1 and Figure 2The conveying driving member 3 includes a driving handle 31, which is located at one side of the installation box 11 in the width direction, and is coaxially connected to one end corresponding to the driving column 5. Therefore, the driving handle 31 can allow the staff to drive the rounding roller 23 to rotate, thereby realizing the conveyance of the nickel strip in the installation box 11.

[0061] Reference Figure 2 The driving handle 31 includes a connecting rod 311, an extension rod 312 and a handle rod 313. The two ends of the extension rod 312 are connected to the connecting rod 311 and the handle rod 313 respectively, and the connecting rod 311 and the handle rod 313 are respectively located at opposite sides of the extension rod 312. The connecting rod 311 and the handle rod 313 are arranged parallel to each other, and one end of the connecting rod 311 away from the extension rod 312 is coaxially connected to the driving column 5. Therefore, the cooperation between the extension rod 312 and the handle rod 313 can drive the rounding roller 23 to rotate.

[0062] In addition, the conveying drive member 3 can also be a motor or other devices that can drive the rounding roller 23 to rotate.

[0063] Therefore, the conveying drive 3 can realize the rotation of the rounding roller 23. When the nickel strip passes through the first roller 21, the rounding roller 23 and the second roller 22 in sequence, the inner bag can be conveyed in the flipper through the rotation of the rounding roller 23.

[0064] Reference Figure 1 and Figure 2 An adjusting driving member 4 is also provided on the driving column 5 .

[0065] Reference Figure 1 and Figure 2 The adjustment drive member 4 includes a drive screw 41, which is axially arranged along the length direction of the installation box 11. A drive hole 112 is formed on one side of the installation box 11 away from the installation plate 12 along its length direction. A drive nut 42 is inserted into the drive hole 112. The outer wall of the drive nut 42 is fixedly connected to the inner wall of the drive hole 112. The drive nut 42 is sleeved on the outer side of the drive screw 41, and the inner wall of the drive nut 42 is connected to the drive screw 41 through a thread. When the drive screw 41 is screwed, the drive screw 41 moves along its own axial direction.

[0066] Reference Figure 1 and Figure 2 The driving screw 41 is located on the side of the driving column 5 away from the mounting plate 12, and one end of the driving screw 41 extends to the outside of the mounting box 11, and the end of the driving screw 41 extending out of the mounting box 11 is coaxially connected to a driving hand wheel 43. The setting of the driving hand wheel 43 facilitates the screwing of the driving screw 41.

[0067] Reference Figure 1 and Figure 2A connecting piece 44 is provided between the driving screw rod 41 and the driving column 5 , and the connecting piece 44 includes a fixed sleeve 441 , which is sleeved on the outside of the driving column 5 , and the fixed sleeve 441 is located in the installation box 11 , and the inner wall of the fixed sleeve 441 is fixedly connected to the driving column 5 .

[0068] Reference Figure 2 and Figure 3 The connecting member 44 further includes a connecting block 442, which is located at one end of the driving screw 41 facing the driving column 5, and the driving screw 41 is rotatably connected to the connecting block 442 along its own circumference, and the connecting block 442 is rotatably connected to the fixed sleeve 441 along the circumference of the fixed sleeve 441. Therefore, when the driving screw 41 rotates, the driving screw 41 can drive the rounding roller 23 to move along the length direction of the installation box 11, and at the same time, the driving handle 31 can drive the rounding roller 23 to rotate normally.

[0069] Reference Figure 2 and Figure 3 The outer wall of the fixed sleeve 441 is provided with a connecting annular groove 443, the connecting block 442 is plugged into the connecting annular groove 443, and the connecting block 442 is slidably connected to the inner wall of the connecting annular groove 443 along the circumference of the fixed sleeve 441. Therefore, the connecting block 442 cooperates with the connecting annular groove 443 to realize the rotational connection between the connecting block 442 and the fixed sleeve 441.

[0070] Reference Figure 2 and Figure 3 A connecting hole 444 is provided on one side of the connecting block 442 facing the driving screw rod 41, and a connecting bearing 445 is inserted into the connecting hole 444. The connecting bearing 445 is sleeved on the outer side of the driving screw rod 41. Therefore, the connecting bearing 445 realizes the rotation connection between the connecting block 442 and the driving screw rod 41.

[0071] Reference Figure 2 and Figure 3 , the connecting annular groove 443 is provided with a limiting annular groove 446 on both sides of the opposite walls, and the limiting annular groove 446 is connected with the connecting annular groove 443. The connecting block 442 is provided with a limiting block 447 on both sides of the opposite walls, and the limiting block 447 is arranged in a one-to-one correspondence with the limiting annular groove 446. The limiting block 447 is plugged and matched with the corresponding limiting annular groove 446, and the limiting block 447 is slidably connected with the inner wall of the corresponding limiting annular groove 446 along the circumference of the rounding roller 23. Therefore, the limiting block 447 and the limiting annular groove 446 realize the axial limitation of the connecting block 442 and the fixed sleeve 441 in the driving screw rod 41.

[0072] In addition, the adjusting driving member 4 can also be a device such as a linear push rod, a hydraulic cylinder or a pneumatic cylinder that can drive the rounding roller 23 to move in a linear direction.

[0073] Therefore, the driving member 4 is adjusted to realize the movement of the rounding roller 23 in a linear direction. When the nickel strip passes through the first roller 21, the rounding roller 23 and the second roller 22 in sequence, the position of the rounding roller 23 is adjusted by adjusting the driving member 4, so that the deformation of the nickel strip can be changed, the bending of the nickel strip can be gradually eliminated, and then the nickel strip can be bent in a certain direction to realize the flipping of the nickel strip.

[0074] The implementation principle of the embodiment of the present application is as follows: In the first step, the nickel strip is inserted into the turner, and then the rounding roller 23 is adjusted so that the rounding roller 23 can press on the nickel strip and deform the nickel strip, thereby conveying the nickel strip in the turner through the conveying drive 3. In order to ensure that the nickel strip can be fed into the turner, the rounding roller 23 is first adjusted to be located on the side of the first roller 21 away from the mounting plate 12, and at this time, the nickel strip loop can pass through the first roller 21, the rounding roller 23 and the second roller 22.

[0075] In the second step, the rounding roller 23 needs to be adjusted to increase the deformation of the nickel strip, and then the nickel strip is transported in the turner through the transport drive 3.

[0076] Repeat the above steps so that the output nickel strip is no longer bent.

[0077] Then, the nickel strip is turned over and sent back into the turning device, and the above steps are repeated to bend the nickel strip into a nickel strip ring again.

[0078] At this time, the inner ring surface of the scrapped nickel band ring is transformed into the outer ring surface of the new nickel band ring, and the outer ring surface of the scrapped nickel band ring is transformed into the inner ring surface of the new nickel band ring, so the new nickel band ring just can be reused.

[0079] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
