Description

Technical Field

[0001] The utility model belongs to the technical field of tungsten wire preparation, and in particular relates to a tungsten wire rope stress release device. Background Art

[0002] The fine tungsten wire processed by large deformation has good toughness, strength and high temperature resistance. Therefore, the tungsten wire rope made of fine tungsten wire is widely used in the pulling rope of single crystal silicon. With the development of single crystal silicon growth technology, the size and weight of single crystal silicon ingots are getting bigger and bigger. The largest single ingot weighs more than one ton, which puts extremely high requirements on the quality of the tungsten wire rope used for pulling and lifting.

[0003] During the winding process of conventional tungsten wire rope, large stress will be generated under the action of traction tension. If the stress is not eliminated in time, the creep resistance of the tungsten wire rope will be seriously reduced during later use, resulting in a reduction in the service life of the tungsten wire rope. Utility Model Content

[0004] In view of this, the utility model aims to provide a tungsten wire rope stress release device, which has a simple structure. The stress of the wound tungsten wire rope is effectively released after passing through the device, thereby solving the problem that the stress after winding affects the creep resistance of the tungsten wire rope.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tungsten wire rope stress release device comprises a plurality of roller discs arranged along the length direction, wherein the roller discs comprise a base, a roller set arranged on the base and an adjustment device; at least two roller discs are arranged, and the planes of the two roller discs to be used in coordination are arranged perpendicular to each other.

[0007] Furthermore, the two roller sets used in combination include a vertical roller set and a horizontal roller set, the base of the vertical roller set is placed vertically, and the base of the horizontal roller set is placed horizontally.

[0008] Furthermore, the roller group includes an upper roller group and a lower roller group, and the upper roller group and the lower roller group are arranged face to face and spaced apart to form a channel for the tungsten wire rope to pass through.

[0009] Furthermore, the rollers of the upper roller group and the lower roller group are arranged in a staggered manner to form a curved channel for the tungsten wire rope to pass through.

[0010] Furthermore, the number of rollers in the upper roller group is one more than the number of rollers in the lower roller group.

[0011] Furthermore, the adjusting device includes a distance adjusting slider and a distance adjusting nut for controlling the distance adjusting slider, and is used to adjust the distance between the rollers of the lower roller group and the rollers of the upper roller group.

[0012] Specifically, a slideway is provided on the base, the distance adjusting slider is movably arranged on the slideway and sleeved with the central axis of the roller, one end of the distance adjusting nut is connected to the bottom end of the distance adjusting slider, and the other end extends out of the base to connect to external power.

[0013] The beneficial effects of the utility model are:

[0014] 1. The stress release device proposed by the utility model has a simple and effective structure. The stress of the wound tungsten wire rope is released by the cooperation of the vertical roller set and the horizontal roller set. The stress release effect is better through the pressure of the roller sets in different directions on both sides.

[0015] 2. The twisted rope body is subjected to bending stress during the bending correction process, and the stress generated by the winding of the tungsten wire rope can be released through a mechanical process, which can significantly improve the high-temperature creep resistance of the tungsten wire rope and extend the service life of the tungsten wire rope;

[0016] 3. The distance between the upper and lower rollers can be changed by adjusting the device to adapt to different tungsten wire rope diameters or meet different resistance requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following specific embodiments are given to further clearly, completely and in detail illustrate the technical solution of the utility model. This embodiment is the best embodiment based on the technical solution of the utility model, but the protection scope of the utility model is not limited to the following embodiments.

[0022] Example 1

[0023] A tungsten wire rope stress release device includes a roller assembly disk, the roller assembly disk includes a base 3 and a roller assembly arranged on the base 3; at least two roller assembly disks are provided, and the two roller assembly disks that need to be used in conjunction are arranged in sequence along the length direction and arranged perpendicular to each other in plane.

[0024] Furthermore, the plurality of roller discs include a vertical roller disc 1 and / or a horizontal roller disc 2, the base 3 of the vertical roller disc 1 is placed vertically, and the base 3 of the horizontal roller disc 2 is placed horizontally. The tungsten wire rope is corrected at different angles by the vertical roller disc 1 and the horizontal roller disc 2 to eliminate stress.

[0025] Furthermore, the roller group includes an upper roller group 201 and a lower roller group 202, which are arranged face to face and spaced apart to form a space for the tungsten wire rope to pass through, serving as a track for the tungsten wire rope to pass through. The rollers on both sides of the track squeeze the tungsten wire rope, and the internal stress of the tungsten wire rope is released by converting it into the rotation of the roller group, thereby releasing the stress generated by the winding of the tungsten wire rope.

[0026] Furthermore, the horizontal heights of the tracks of the vertical roller assembly disc 1 and the horizontal roller assembly disc 2 are consistent, so that the tungsten wire rope can pass through the tracks in sequence without adjusting the height.

[0027] Specifically, the upper roller group and the lower roller group are both provided with a plurality of radially arranged rollers.

[0028] Furthermore, the rollers of the upper roller group 201 and the lower roller group 202 are arranged in a staggered manner.

[0029] Furthermore, the number of rollers in the upper roller set 201 is one more than the number of rollers in the lower roller set 202 .

[0030] Furthermore, the lower roller group 202 is provided with an adjusting device for adjusting the distance between the rollers of the lower roller group 202 and the rollers of the upper roller group 201, and the adjusting device includes a distance adjusting slider 204 and a distance adjusting nut 203 for controlling the distance adjusting slider 204. By adjusting the distance between the rollers of the upper and lower roller groups, tungsten wire ropes of different radii can be adapted.

[0031] Specifically, the base 3 is provided with a slideway for the distance adjustment slider 204 to slide. The distance adjustment slider 204 is movably arranged on the slideway and sleeved with the central axis of the roller. One end of the distance adjustment nut 203 is connected to the bottom end of the distance adjustment slider 204, and the other end extends out of the base 3 to connect to an external power. By pulling the adjustment nut arranged outside the base 3, the distance adjustment slider 204 is driven to move, thereby adjusting the position of the roller.

[0032] As an option, each roller of the lower roller assembly 202 is provided with an adjusting device, and each adjusting device can also control the movement separately.

[0033] As an option, the upper roller set 201 can also be fixedly arranged on the base 3.

[0034] The stress release device can be used in conjunction with a support frame or a fixing seat to fix the two roller assembly discs to ensure the stability of the device when the tungsten wire rope passes through.

[0035] Example 2

[0036] Compared with the aforementioned first embodiment, the difference is that, in this embodiment, there are two roller assemblies, namely a vertical roller assembly 1 and a horizontal roller assembly 2 placed in sequence, and the tungsten wire rope passes through the tracks of the vertical roller assembly 1 and the horizontal roller assembly 2 in sequence.

[0037] Example 3

[0038] Compared with the aforementioned first embodiment, the difference is that, in this embodiment, there are two roller assemblies, namely a horizontal roller assembly 2 and a vertical roller assembly 1 placed in sequence, and the tungsten wire rope passes through the tracks of the horizontal roller assembly 2 and the vertical roller assembly 1 in sequence.

[0039] As an option, the number of rollers in the upper roller group 201 is 10-20. Too few rollers will result in the stress relief effect not meeting the requirements, and too many rollers will cause too much resistance and affect the effect. Therefore, a group preferably has 10-20 rollers.

[0040] In summary, in the tungsten wire rope stress release device of the utility model, the vertically placed roller assembly disk and the horizontally placed roller assembly disk cooperate, so that the wound tungsten wire rope is subjected to pressure when passing through the roller assembly, and the internal stress of the tungsten wire rope is released by being converted into the rotation of the roller assembly, thereby improving the service life of the tungsten wire rope.
