Abstract
Description
Technical Field
[0001] The utility model relates to the field of stress removal of strip materials, in particular to a strip stress removal device. Background Art
[0002] In daily life and work, the copper strips used in electronic products need to be presented to us after being stamped and going through cumbersome processes. The copper strips we produce come in various specifications of width and thickness. The materials from the copper strip factory have different widths and are cut into different widths according to customer requirements. For the production of conventional materials, we use: a feeding rack - a leveling machine - a punching press. The flatness of the products produced can meet the requirements. However, if the internal stress is large and the deformation is large, the products produced will have an S shape. During the slitting process, the copper strip factory will have a simple internal stress removal process. Due to the different thicknesses and widths of the materials, the simple internal stress removal by the copper strip factory cannot completely remove the stress.
[0003] How to effectively remove the stress of the strip material is the problem to be solved. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a strip stress removal device, which solves the problem of ineffective stress removal of strip materials.
[0005] To achieve the above object, the technical solution adopted by the utility model is:
[0006] The utility model provides a strip stress removal device, which includes a bracket and a rotating assembly. The rotating assembly is arranged on the bracket, and is characterized in that,
[0007] The rotating assembly includes a motor, a driving wheel, a first driven wheel and a second driven wheel. The motor is arranged on the bracket, and the driving wheel is connected to the driving end of the motor;
[0008] The first driven wheel and the second driven wheel are rotatably arranged on the bracket at intervals. The feeding wheel, the driving wheel, the first driven wheel, the second driven wheel and the discharging wheel are all in the flowing direction of the strip material. The feeding wheel, the driving wheel, the first driven wheel, the second driven wheel and the discharging wheel support the strip material alternately, and the feeding wheel, the driving wheel, the first driven wheel, the second driven wheel and the discharging wheel make the strip material bend and flow;
[0009] A feeding wheel and a discharging wheel are also rotatably arranged on the bracket, and the feeding wheel and the discharging wheel are respectively located on both sides of the rotating assembly;
[0010] The diameter of the feeding wheel is smaller than that of the discharging wheel.
[0011] Optionally, the driving wheel, the first driven wheel, and the second driven wheel have the same diameter, and the diameters of the driving wheel, the first driven wheel, and the second driven wheel are greater than the diameter of the feeding wheel and less than the diameter of the discharging wheel.
[0012] Further, the positions of the driving wheel, the feeding wheel, and the discharging wheel are higher than the positions of the first driven wheel and the second driven wheel.
[0013] Optionally, first protective walls and second protective walls are respectively arranged on two sides of the driving wheel, the first driven wheel, the second driven wheel, the feeding wheel, and the discharging wheel. The first protective walls and the second protective walls extend in a circle, and are located on the moving path of the material belt between the first protective walls and the second protective walls.
[0014] Optionally, a first support rod and a second support rod are arranged on the bracket.

[0018] Due to the application of the above technical solutions, the present utility model has the following advantages compared with the prior art:
[0019] A stress-relieving device for a strip of material according to the present utility model. Since the strip of material first passes through a feed wheel with a small diameter, the strip of material has more bends on the feed wheel. Then the strip of material passes through a first driven wheel and is bent again, then passes through a driving wheel and is bent, then passes through a second driven wheel and is bent, and finally passes through a discharge wheel and exits. The diameter of the discharge wheel is larger than that of the feed wheel. Therefore, when the strip of material passes through the discharge wheel, the degree of bending is small, and the strip of material tends to be smooth at the discharge wheel. After undergoing forward and reverse bending in different directions, the stress of the strip of material is removed, thus solving the problem that the stress of the strip of material cannot be effectively removed.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0028] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] As Figure 1 and Figure 2 and Figure 3 shown, it includes a bracket 1 and a rotating assembly 2. The rotating assembly 2 is arranged on the bracket 1, and the tape 8 is driven to move by the rotating assembly 2. At the same time, the tape 8 is also bent by the rotating assembly 2 to relieve stress.
[0030] The rotating assembly 2 includes a motor 21, a driving wheel 22, a first driven wheel 23 and a second driven wheel 24. The motor 21 is arranged on the bracket 1, and the driving wheel 22 is connected to the driving end of the motor 21. The motor 21 drives the driving wheel 22 to rotate.
[0031] An inlet wheel 3 and an outlet wheel 4 are also rotatably arranged on the bracket 1. The inlet wheel 3 and the outlet wheel 4 are respectively located on both sides of the rotating assembly 2. The tape 8 first overlaps on the inlet wheel 3, then comes out and overlaps on the first driven wheel 23, then comes out and overlaps on the driving wheel 22, then comes out and overlaps on the second driven wheel 24, and finally overlaps on the outlet wheel 4 to reach the next station. The next station also has a traction effect on the tape 8.
[0032] The first driven wheel 23 and the second driven wheel 24 are rotatably arranged on the bracket 1 at an interval. The driving wheel 22, the first driven wheel 23 and the second driven wheel 24 are overlapped with the tape. When the driving wheel 22 rotates, the first driven wheel 23 and the second driven wheel 24 are driven to rotate through the tape 8. At the same time, the tape 8 is moving. The inlet wheel 3, the driving wheel 22, the first driven wheel 23, the second driven wheel 24 and the outlet wheel 4 are all in the flow direction of the tape 8. The inlet wheel 3, the driving wheel 22, the first driven wheel 23, the second driven wheel 24 and the outlet wheel 4 support the tape 8 alternately. The inlet wheel 3, the driving wheel 22, the first driven wheel 23, the second driven wheel 24 and the outlet wheel 4 cause the tape 8 to bend and flow, so that both the front and back sides of the tape 8 are bent, thereby releasing stress.
[0033] The driving wheel 22, the first driven wheel 23 and the second driven wheel 24 have the same diameter, that is, the driving wheel 22, the first driven wheel 23 and the second driven wheel 24 are of the same size. The diameters of the driving wheel 22, the first driven wheel 23 and the second driven wheel 24 are larger than the diameter of the feeding wheel 3, and the diameters of the driving wheel 22, the first driven wheel 23 and the second driven wheel 24 are smaller than the diameter of the discharging wheel 4. In this way, the curvature of the material tape 8 is small when it is bent by the feeding wheel 3. When the material tape 8 passes through the driving wheel 22, the first driven wheel 23 and the second driven wheel 24, the curvature becomes larger. Finally, when it passes through the discharging wheel 4, the curvature becomes larger again.
[0034] The positions of the driving wheel 22, the feeding wheel 3 and the discharging wheel 4 are higher than the positions of the first driven wheel 23 and the second driven wheel 24. In this application, the driving wheel 22, the feeding wheel 3 and the discharging wheel 4 are at the same height, the first driven wheel 23 and the second driven wheel 24 are at the same height, and the driving wheel 22 is located above the middle of the first driven wheel 23 and the second driven wheel 24.
[0035] First guard walls 25 and second guard walls 26 are respectively arranged on both sides of the driving wheel 22, the first driven wheel 23, the second driven wheel 24, the feeding wheel 3 and the discharging wheel 4. The first guard walls 25 and the second guard walls 26 extend around for one week. The material tape 8 is between the first guard walls 25 and the second guard walls 26 and passes through between the first guard walls 25 and the second guard walls 26, which can prevent the material tape 8 from falling off the driving wheel 22, the first driven wheel 23, the second driven wheel 24, the feeding wheel 3 and the discharging wheel 4. The first guard walls 25 and the second guard walls 26 protrude from the outer peripheral surfaces of the driving wheel 22, the first driven wheel 23, the second driven wheel 24, the feeding wheel 3 and the discharging wheel 4.
[0036] A first support rod 11 and a second support rod 12 are arranged on the bracket 1. A first slider 110 is slidably arranged on the first support rod 11, and a second slider 120 is slidably arranged on the second support rod 12. The first driven wheel 23 is rotatably arranged between the first slider 110 and the second slider 120. When the material tape 8 is pulled by the next working station, it is not always pulled continuously. Therefore, when the material tape 8 is pulled by the next working station, both the first slider 110 and the second slider 120 slide upward. When the material tape 8 is not pulled by the next working station, both the first slider 110 and the second slider 120 slide downward. During this process, since the motor 21 continues to drive the driving wheel 22 and the material tape 8 continues to flow, temporary storage of the material tape 8 can be realized, and the material tape 8 can be stored between the first driven wheel 23, the feeding wheel 3 and the driving wheel 22.
[0037] The first support rod 11 is also sleeved with a first spring 111 and a second spring 112, and two ends of the first slider 110 respectively abut against the first spring 111 and the second spring 112, and the second support rod 12 is also sleeved with a third spring 121 and a fourth spring 122, and two ends of the second slider 120 respectively abut against the third spring 121 and the fourth spring 122, so that the second slider 120 rises and falls slowly, and the first passive wheel 23 rises and falls slowly as well. Therefore, in this process, the first passive wheel 23 and the material belt 8 have a long rolling and squeezing time, and the material belt 8 is bent in contact with the first passive wheel 23 for a long time, which is conducive to removing the stress of the material belt 8 on the first passive wheel 23.
[0038] The bracket 1 is also provided with a third support rod 13 and a fourth support rod 14, and the third support rod 13 is slidably provided with a third slider 130, and the fourth support rod 14 is slidably provided with a fourth slider 140, and the second passive wheel 24 is rotatably provided on the third slider 130 and the fourth slider 140. When the material belt 8 is pulled at the next workstation, the second passive wheel 24 is forced to be lifted upward, so the third slider 130 and the fourth slider 140 rise together, and when the pulling of the material belt 8 is suspended at the next workstation, the third slider 130 and the fourth slider 140 descend together, and the second passive wheel 24 falls back and resets. When falling back, since the motor 21 continues to drive the driving wheel 22, the material belt 8 continues to flow, so the material belt 8 is stored between the second passive wheel 24 and the driving wheel 22 and the discharge wheel 4.
[0039] The third support rod 13 is also sleeved with a fifth spring 131 and a sixth spring 132, and two ends of the third slider 130 respectively abut against the fifth spring 131 and the sixth spring 132, and the fourth support rod 14 is sleeved with a seventh spring 141 and an eighth spring 142, and two ends of the fourth slider 140 respectively abut against the seventh spring 141 and the eighth spring 142, so that the rising or falling speed of the third slider 130 and the fourth slider 140 slows down, so the time for the material belt 8 to be attached to the second passive wheel 24 is long, and the time for the second passive wheel 24 to roll and squeeze the material belt 8 is longer, that is, the bending time of the material belt 8 on the second passive wheel 24 is longer, which is conducive to the removal of the stress of the material belt 8 on the second passive wheel 24.
[0040] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
