Description
Technical Field
[0001] The utility model relates to the technical field of steel cord production, in particular to a deformation wheel set for descaling the surface of steel cord. Background Art
[0002] In the production process of steel cord, the first process is the descaling process, and several groups of deformation wheels are required to repeatedly bend the steel cord rod. The purpose is to remove the scale on the surface of the rod completely for subsequent production. During this process, the rod is subjected to strong tensile and compressive stresses. If the deformation wheels rotate inflexibly and the steel wire has sliding friction with the deformation wheels, it is very easy to cause the formation of deformation martensite on the surface of the steel wire. The formation of deformation martensite will lead to an increase in subsequent wire breakage, which is not conducive to the smooth progress of production.
[0003] Currently, the commonly adopted methods in the industry are as follows: conduct a comprehensive inspection of the surface of the steel wire, and if there are any abnormalities, check the situation of the deformation wheels in reverse; regularly check and replace the deformation wheels. The above methods are all subsequent remedial measures, which are not conducive to timely discovering and solving problems. After wire breakage, only the broken wire can be reconnected by welding in the later stage, but the breaking force of the welding point can only reach 40% of the original, and there are special requirements for the using parts of the products with welding, and the product price will also be reduced. Summary of the Invention
[0004] In view of the technical problems existing in the descaling deformation wheel set of steel cord in the prior art, the first aspect of the utility model provides a deformation wheel set for descaling the surface of steel cord, including:
[0005] A wire guiding wheel set, including a first wire guiding wheel set and a second wire guiding wheel set, and the first wire guiding wheel set and the second wire guiding wheel set are linearly distributed;
[0006] A first deformation wheel and a second deformation wheel, which are arranged on one side of the wire guiding wheel set, and the steel wire sequentially bypasses the first wire guiding wheel set, the first deformation wheel, the second deformation wheel and the second wire guiding wheel set, and is deformed at the first deformation wheel and the second deformation wheel;
[0007] A temperature detection component, which is used to monitor the surface temperatures of the first deformation wheel and the second deformation wheel;
[0008] An alarm, which is connected to the temperature detection component;
[0009] Wherein, the temperature detection component includes a first temperature detector and a second temperature detector. The first temperature detector faces the wire passing groove on the surface of the first deformation wheel and is used to monitor the temperature of the steel wire on the surface of the first deformation wheel. The second temperature detector faces the wire passing groove on the surface of the second deformation wheel and is used to monitor the temperature of the steel wire on the surface of the second deformation wheel;
[0010] When the first temperature detector or the second temperature detector monitors that the temperature exceeds 85 degrees Celsius, the alarm will sound.

When the first driver is in the shortened position and the second driver is in the extended position, the steel wire bypasses the second deformation wheel from the second wire guiding wheel and does not contact the first deformation wheel. When the first driver is in the extended position and the second driver is in the shortened position, the steel wire bypasses the third wire guiding wheel from the first deformation wheel and does not contact the second deformation wheel.
[0015] Preferably, when the first temperature detector monitors that the temperature exceeds 85 degrees Celsius, the first driver moves from the extended position to the shortened position. When the second temperature detector monitors that the temperature exceeds 85 degrees Celsius, the second driver moves from the extended position to the shortened position.
[0016] Compared with the prior art, the advantages of the present utility model are as follows:

Description of the Drawings
[0018] The accompanying drawings are not intended to be drawn to scale. In the accompanying drawings, each identical or nearly identical component shown in each figure may be denoted by the same reference numeral. For the sake of clarity, not every component is labeled in each figure. Now, embodiments of various aspects of the present utility model will be described by way of example and with reference to the accompanying drawings, wherein:
[0019] Figure 1 is a schematic structural view of a deformed wheel set for descaling the surface of steel cord shown in the present utility model. Detailed implementation manners
[0020] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.
[0021] As a result of the inventor's long-term analysis of the replacement and inspection of the deformed wheels, the main reason for the scratched surface of the steel wire caused by the deformed wheels is the poor rotation of the deformed wheels and the bearings. All of the above reasons will cause sliding friction between the deformed wheels and the steel wire, thereby increasing the surface temperature. Therefore, monitoring the surface temperature of the deformed wheels can indirectly determine the running condition between the deformed wheels and the steel wire.
[0022] Therefore, this solution aims to install an infrared temperature detector on the existing deformed wheels, and monitor the running condition by setting different temperature control requirement ranges for different deformed wheels.
[0023] As Figure 1 shown, a first aspect of the present utility model provides a deformed wheel set for descaling the surface of steel cord, which includes a wire guiding wheel set 10, a first deformed wheel 21, a second deformed wheel 22, a temperature detection component, and an alarm.
[0024] As Figure 1 shown, the wire guiding wheel set 10 includes a first wire guiding wheel set and a second wire guiding wheel set, and the first wire guiding wheel set and the second wire guiding wheel set are linearly distributed. Among them, the first wire guiding wheel set is located on the left side of the deformed wheel, and the second wire guiding wheel set is located on the right side of the deformed wheel.
[0025] The deformed wheels include a first deformed wheel 21 and a second deformed wheel 22, which are arranged on one side of the wire guiding wheel set 10. The steel wire sequentially bypasses the first wire guiding wheel set, the first deformed wheel 21, the second deformed wheel 22, and the second wire guiding wheel set, and is deformed at the first deformed wheel 21 and the second deformed wheel 22.
[0026] Furthermore, the temperature detection component is used to monitor the surface temperatures of the first deformed wheel 21 and the second deformed wheel 22, and the alarm is connected to the temperature detection component.
[0027] Among them, the temperature detection component includes a first temperature detector 31 and a second temperature detector 32. The first temperature detector 31 faces the wire groove on the surface of the first deformation wheel 21 and is used to monitor the temperature of the steel wire on the surface of the first deformation wheel 21. The second temperature detector 32 faces the wire groove on the surface of the second deformation wheel 22 and is used to monitor the temperature of the steel wire on the surface of the second deformation wheel 22.
[0028] In this way, by monitoring the temperature of the steel wire on the surfaces of the first deformation wheel 21 and the second deformation wheel 22, it can be determined whether there is sliding friction between the steel wire and the surfaces of the deformation wheels. When the temperature exceeds a predetermined value, there is a risk of wire breakage for the steel wire. When the first temperature detector 31 or the second temperature detector 32 detects that the temperature exceeds 85 degrees Celsius, the alarm will sound, and the worker can promptly check the rotation conditions of the first deformation wheel 21 or the second deformation wheel 22 to eliminate abnormalities.
[0029] In an alternative embodiment, as Figure 1 shown, the first wire guiding wheel group includes a first wire guiding wheel 11 and a second wire guiding wheel 12. The first wire guiding wheel 11 and the second wire guiding wheel 12 are respectively located on the first side and the second side of the steel wire. The second wire guiding wheel group includes a third wire guiding wheel 13 and a fourth wire guiding wheel 14. The third wire guiding wheel 13 and the fourth wire guiding wheel 14 are respectively located on the first side and the second side of the steel wire.
[0030] Furthermore, the first deformation wheel 21 is located on the second side of the second wire guiding wheel 12, and the second deformation wheel 22 is located on the second side of the third wire guiding wheel 13. The steel wire sequentially bypasses the first wire guiding wheel 11, the second wire guiding wheel 12, the first deformation wheel 21, the second deformation wheel 22, the third wire guiding wheel 13, and the fourth wire guiding wheel 14.
[0031] In this way, when the steel wire winds around the wire guiding wheels and the deformation wheels, its winding trajectory is in a shape like a "Ji" character. It can be seen that the steel wire includes four deformation regions. The first deformation region is at the second wire guiding wheel 12, the second deformation region is at the first deformation wheel 21, the third deformation region is at the second deformation wheel 22, and the fourth deformation region is at the third wire guiding wheel 13. By applying repeated bending to the steel wire, the scale on the surface of the steel wire can be removed completely.
[0032] In a preferred embodiment, the maximum distance between the first deformation wheel 21 and the second deformation wheel 22 is L1, the minimum distance between the second wire guiding wheel 12 and the third wire guiding wheel 13 is L2, and the distance between the axes of the second wire guiding wheel 12 and the third wire guiding wheel 13 is L3, where L2 < L1 < L3.
[0033] Combined with Figure 1As shown, the axis connection line of the second wire guiding wheel 12 and the third wire guiding wheel 13 is parallel to the axis connection line of the first deformation wheel 21 and the second deformation wheel 22, and the distance between the second wire guiding wheel 12 and the third wire guiding wheel 13 is slightly greater than the distance between the first deformation wheel 21 and the second deformation wheel 22. Therefore, the steel cord can generate large-angle deformation.
[0034] Furthermore, in order to continue descaling after detecting abnormal heat of the first deformation wheel 21 or the second deformation wheel 22, a linear driver is also provided. The linear driver includes a first driver 41 connected to the first deformation wheel 21 and a second driver 42 connected to the second deformation wheel 22. The first driver 41 and the second driver 42 include an extended position and a shortened position. When the first driver 41 is in the shortened position and the second driver 42 is in the extended position, the steel wire bypasses the second deformation wheel 22 from the second wire guiding wheel 12 and does not contact the first deformation wheel 21. When the first driver 41 is in the extended position and the second driver 42 is in the shortened position, the steel wire bypasses the third wire guiding wheel 13 from the first deformation wheel 21 and does not contact the second deformation wheel 22.
[0035] In this way, when the first temperature detector 31 monitors that the temperature exceeds 85 degrees Celsius, the first driver 41 moves from the extended position to the shortened position. At this time, the steel wire bypasses the second deformation wheel 22 from the second wire guiding wheel 12 and does not contact the first deformation wheel 21, and large-angle deformation can be formed through the second deformation wheel 22 and the third wire guiding wheel 13; when the second temperature detector 32 monitors that the temperature exceeds 85 degrees Celsius, the second driver 42 moves from the extended position to the shortened position. At this time, the steel wire bypasses the third wire guiding wheel 13 from the first deformation wheel 21 and does not contact the second deformation wheel 22, and large-angle deformation is provided by the second wire guiding wheel 12 and the first deformation wheel 21. During this process, the deformation wheel in the compressed state can be inspected or the bearing can be replaced.
[0036] Combined with the above embodiments, the utility model sets a temperature monitoring device outside the two deformation wheels. By monitoring the temperature of the deformation wheels, the operating conditions of the deformation wheels can be intuitively obtained. Once the temperature is abnormal, it can be judged that the current deformation wheel is abnormal, and maintenance and replacement can be carried out in time, which can reduce the cost of regularly replacing the deformation wheels. In addition, by timely solving the deformation wheels with abnormal operation, the defective products generated by the current method of inspecting the products to reverse-check the deformation wheels are reduced.
[0037] Although the utility model has been disclosed above with preferred embodiments, it is not intended to limit the utility model. Those with ordinary knowledge in the technical field to which the utility model belongs can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to what is defined by the claims.
