Description

Technical Field

[0001] The invention belongs to the technical field of metal wire material straightening, and in particular is a thermocouple wire straightening device and an operation method and application thereof. Background Art

[0002] Thermocouple sensors are the most widely used thermoelectric sensors in temperature measurement and the most commonly used temperature detection elements in industry. They have the advantages of simple structure, convenient manufacturing, wide measurement range, small thermal inertia, high accuracy, and convenient remote transmission of output signals. They are widely used in steel, chemical, electric power, metallurgy and other industries, and the market demand is also growing.

[0003] In the related art, the thermocouple wire of the thermocouple sensor will bend to a certain extent during the manufacturing or use process, resulting in a change in the resistance of the thermocouple sensor, which reduces the measurement accuracy and the risk of breakage of the thermocouple wire. The thermocouple wire needs to be straightened and repaired. At present, a roller straightening machine is commonly used to straighten the thermocouple wire. Several groups of rollers are arranged up and down. The rollers are provided with slots to fix the left and right directions without displacement. When the thermocouple wire passes through the upper and lower rollers, the rollers exert a force on the bent thermocouple wire to straighten the wire. However, when the bending degree of the thermocouple wire is large, it is often impossible to completely straighten it at one time. It is necessary to manually clamp the thermocouple wire repeatedly. The straightening efficiency is low and the labor intensity is high. If the wire is not completely straightened, the thermocouple wire will easily bend and deform again. In addition, in order to facilitate storage after production, the thermocouple wire will be coiled and wound on a wire reel. It also needs to be straightened before use.

[0004] Therefore, there is an urgent need for a thermocouple wire straightening device and an operating method thereof to achieve the purpose of improving the straightening efficiency, reducing manual intervention, and eliminating the need for repeated clamping and straightening. Summary of the invention

[0005] The object of the present invention is to provide a thermocouple wire straightening device and an operating method and application thereof, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] Specifically, the first aspect of the present invention discloses a thermocouple wire straightening device, comprising:

[0007] A frame, wherein a straightening fixture is arranged on the top of the frame, and bearing seats are arranged at both ends of the straightening fixture;

[0008] A motor is arranged at the lower part of the frame, and a belt is arranged on the output shaft of the motor;

[0009] A wheel axle is arranged at one end of the straightening fixture, the output shaft of the motor is connected to the wheel axle through the belt, the other end of the straightening fixture is connected to the output shaft of the bearing seat, and an eccentric shaft is arranged in the middle of the straightening fixture;

[0010] The wheel axle hole and the bearing seat output shaft hole are concentric holes;

[0011] The eccentric shaft hole is offset relative to the wheel shaft hole and the bearing seat output shaft hole.

[0012] The thermocouple wire straightening device according to the present invention has at least the following beneficial effects:

[0013] The thermocouple wire straightening device drives the wheel shaft to rotate at high speed through the belt of the motor, and drives the straightening tool to rotate at high speed at the same time, and the eccentric shaft is offset relative to the wheel shaft hole and the bearing seat output shaft hole, so that centrifugal force is generated when the straightening tool rotates at high speed, and the thermocouple wire inserted into the wheel shaft hole, the eccentric shaft hole and the bearing seat output shaft hole is continuously subjected to high-speed centrifugal swing. The centrifugal force eliminates or reduces the internal stress of the thermocouple wire, thereby realizing the straightening of the thermocouple wire, effectively improving the elasticity and ductility of the thermocouple wire, so that it can maintain better performance in subsequent processing or use;

[0014] The thermocouple wire passes through multiple axial holes, so that the force is evenly applied, and the force applied during the rotation process is more dispersed, which can eliminate or reduce the internal stress of the bending part of the thermocouple wire to the maximum extent, so as to achieve a high-precision straightening effect. Compared with the traditional straightening method, it greatly reduces the straightening time and improves the straightening efficiency of the thermocouple wire. At the same time, it reduces manual intervention, reduces labor intensity, and improves the safety and reliability of operation;

[0015] In addition, the thermocouple wire straightening device has a compact structure and occupies a small space. Thermocouple wires with a relatively high degree of curvature can be straightened once through the device without multiple clamping, which effectively enhances the straightening efficiency of the thermocouple wires and reduces processing costs.

[0016] As a further solution of the present invention: the eccentric shaft hole is arbitrarily offset in the circumferential direction relative to the wheel shaft hole and the bearing seat output shaft hole, and the offset range is 1mm-20mm.

[0017] By setting the eccentric shaft hole to be arbitrarily offset relative to the wheel shaft hole and the bearing seat output shaft hole in the circumferential direction, with an offset range of 1mm-20mm, the thermocouple wire generates centrifugal force when the eccentric shaft is offset relative to the wheel shaft hole and the bearing seat output shaft hole in any circumferential direction and when the straightening tooling is driven by a motor to rotate at a high speed. Through continuous high-speed centrifugal swing, the thermocouple wire can eliminate or reduce internal stress, thereby achieving straightening of the thermocouple wire. At the same time, the offset range of the eccentric shaft can be adjusted for thermocouple wires of different diameters, thereby improving the adaptability and versatility of the device.

[0018] As a further solution of the present invention: the straightening tool includes a box body, the wheel axle is arranged at one end of the box body, and the output shaft of the bearing seat is arranged at the other end of the box body.

[0019] As a further solution of the present invention: support rods are respectively provided on both sides of the box body, and the eccentric shaft is respectively connected to the support rods on both sides.

[0020] Since the straightening tooling includes a box body, the wheel axle is arranged at one end of the box body, and the output shaft of the bearing seat is arranged at the other end of the box body; support rods are respectively arranged on both sides of the box body, and the eccentric shaft is respectively connected to the support rods on both sides. The wheel axle and the output shaft of the bearing seat are respectively connected by the two ends of the box body, which can effectively protect them and prevent dust and other pollutants from entering the inside of the bearing and affecting the device. The eccentric shaft is positioned and fixed by the support rods on both sides of the box body, and the power of the motor can be transmitted to the box body through the wheel axle, and then transmitted to the eccentric shaft through the box body, thereby ensuring the stability of the eccentric shaft during high-speed rotation, which is conducive to the efficient straightening of the thermocouple wire.

[0021] As a further solution of the present invention: a through slot is provided on the top of the frame, and the through slot is provided corresponding to the box body;

[0022] As a further solution of the present invention: the area of ​​the through slot is larger than the area of ​​the box body.

[0023] Since a through slot is provided on the top of the frame, the through slot is provided corresponding to the box body, and the area of ​​the through slot is larger than the area of ​​the box body, the box body is not disturbed by the platform on the top of the frame during high-speed rotation, which can effectively reduce the height of the straightening device, simplify the overall structure, reduce the space occupied by the device, and can meet different site layouts and production requirements.

[0024] As a further solution of the present invention: the rotation speed of the motor is 2800RPM-3200RPM.

[0025] Since the motor speed is 2800RPM-3200RPM, it can drive the straightening device to rotate at high speed and generate centrifugal force, which can effectively eliminate or reduce the internal stress of the thermocouple wire, so that the thermocouple wire is continuously swung at high speed centrifugally, thereby achieving the purpose of efficient straightening.

[0026] The second aspect of the present invention discloses an operating method of a thermocouple wire straightening device, comprising the following steps:

[0027] S1, inserting the thermocouple wire through the shaft hole of the wheel shaft, and passing through the shaft hole of the eccentric shaft, and finally passing the thermocouple wire out from the output shaft hole of the bearing seat;

[0028] S2. Start the motor, which rotates at high speed, drives the wheel shaft to rotate at high speed through the belt, and drives the eccentric shaft, the box body and the output shaft of the bearing seat to rotate at high speed, thereby generating centrifugal force.

[0029] S3. The thermocouple wire is continuously subjected to high-speed centrifugal swing under the high-speed rotation of the eccentric shaft, thereby eliminating or reducing the internal stress of the thermocouple wire.

[0030] The operation method of the thermocouple wire straightening device can efficiently perform centrifugal force straightening on the thermocouple wire, effectively improving the uniform straightening effect and flexible adaptability of the thermocouple wire, shortening the straightening time, reducing human intervention, and improving production efficiency and product quality; at the same time, the device can perform centrifugal force straightening on different small-diameter metal wire materials, enhancing the versatility and practicality of the device.

[0031] The third aspect of the present invention discloses the application of a thermocouple wire straightening device in the field of straightening small-diameter metal wire materials.

[0032] The thermocouple wire straightening device can efficiently straighten small-diameter metal wires, thereby improving the applicability and versatility of the device, ensuring that different types of small-diameter metal wires meet their performance requirements after straightening, and improving the quality and stability of the products after straightening. In addition, the device can meet the needs of one-time straightening of small-diameter metal wire materials without the need for multiple straightening operations, thereby avoiding the possibility of residual bending of the metal wire in traditional straightening methods, which may lead to re-bending and deformation, and effectively improving the straightening efficiency of small-diameter metal wire materials.

[0033] As a further solution of the present invention: the diameter range of the small-diameter metal wire material is 0.5mm-3mm.

[0034] Since the diameter range of small-diameter wire materials is 0.5mm-3mm, the wire materials in this diameter range can be straightened quickly and efficiently, shortening the straightening time, improving the straightening efficiency, and meeting the straightening needs of large quantities of wire materials.

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the technical solution of the present invention is further specifically described below by way of examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as a limitation of the present invention.

[0040] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0041] like Figure 1 The embodiments of the present invention shown in the figure disclose a thermocouple wire straightening device in the first aspect, comprising: a frame 1, a straightening fixture 2 is arranged on the top of the frame 1, and bearing seats 3 are arranged at both ends of the straightening fixture 2; a motor 4 is arranged at the lower part of the frame 1, and a belt 401 is arranged on the output shaft of the motor 4; an axle 201 is arranged at one end of the straightening fixture 2, and the output shaft of the motor 4 is connected to the axle 201 through the belt 401, and the other end of the straightening fixture 2 is connected to the output shaft of the bearing seat 3, and an eccentric shaft 202 is arranged in the middle of the straightening fixture 2; the axial hole of the axle 201 and the axial hole of the output shaft of the bearing seat 3 are concentric axial holes; the axial hole of the eccentric shaft 202 is offset relative to the axial hole of the axle 201 and the axial hole of the output shaft of the bearing seat 3.

[0042] Specifically, the thermocouple wire straightening device drives the wheel shaft 201 to rotate at high speed through the belt 401 of the motor 4, and drives the straightening tool 2 to rotate at high speed at the same time, and the eccentric shaft 202 is offset relative to the shaft hole of the wheel shaft 201 and the shaft hole of the output shaft of the bearing seat 3, so that centrifugal force is generated when the straightening tool 2 rotates at high speed, and the thermocouple wire inserted into the shaft hole of the wheel shaft 201, the hole of the eccentric shaft 202 and the output shaft hole of the bearing seat 3 is continuously subjected to high-speed centrifugal swing. The centrifugal force eliminates or reduces the internal stress of the thermocouple wire, thereby realizing the straightening of the thermocouple wire, effectively improving the elasticity and ductility of the thermocouple wire, so that it can maintain better performance in subsequent processing or use;

[0043] The thermocouple wire passes through multiple axial holes, so that the force is evenly applied, and the force applied during the rotation process is more dispersed, which can eliminate or reduce the internal stress of the bending part of the thermocouple wire to the maximum extent, so as to achieve a high-precision straightening effect. Compared with the traditional straightening method, it greatly reduces the straightening time and improves the straightening efficiency of the thermocouple wire. At the same time, it reduces manual intervention, reduces labor intensity, and improves the safety and reliability of operation;

[0044] In addition, the thermocouple wire straightening device has a compact structure and occupies a small space. Thermocouple wires with a relatively high degree of curvature can be straightened once through the device without multiple clamping, which effectively enhances the straightening efficiency of the thermocouple wires and reduces processing costs.

[0045] Furthermore, the axial hole of the eccentric shaft 202 is arbitrarily offset in the circumferential direction relative to the axial hole of the wheel axle 201 and the axial hole of the output shaft of the bearing seat 3, and the offset range is 1mm-20mm.

[0046] Specifically, the axial hole of the eccentric shaft 202 is arbitrarily offset relative to the axial hole of the wheel axle 201 and the axial hole of the output shaft of the bearing seat 3 in the circumferential direction, and the offset range is 1mm-20mm. When the eccentric shaft 202 is offset relative to the axial hole of the wheel axle 201 and the axial hole of the output shaft of the bearing seat 3 in any circumferential direction and the straightening tool 2 is driven by the motor 4 to rotate at a high speed, centrifugal force is generated on the thermocouple wire. Through continuous high-speed centrifugal swing, the internal stress of the thermocouple wire can be eliminated or reduced, thereby realizing the straightening of the thermocouple wire. At the same time, the offset range of the eccentric shaft 202 can be adjusted for thermocouple wires of different diameters, thereby improving the adaptability and versatility of the device.

[0047] like Figure 1 As shown, the straightening tool 2 includes a box body 203, the wheel axle 201 is arranged at one end of the box body 203, and the output shaft of the bearing seat 3 is arranged at the other end of the box body 203; support rods 204 are respectively arranged on both sides of the box body 203, and the eccentric shaft 202 is respectively connected to the support rods 204 on both sides.

[0048] Specifically, since the straightening tool 2 includes a box body 203, the wheel axle 201 is arranged at one end of the box body 203, and the output shaft of the bearing seat 3 is arranged at the other end of the box body 203; support rods 204 are respectively arranged on both sides of the box body 203, and the eccentric shaft 202 is respectively connected to the support rods 204 on both sides. The wheel axle 201 and the output shaft of the bearing seat 3 are respectively connected at both ends of the box body 203, which can effectively protect them and prevent dust and other pollutants from entering the bearing and affecting the device. The eccentric shaft 202 is positioned and fixed by the support rods 204 on both sides of the box body 203, and the power of the motor 4 can be transmitted to the box body 203 through the wheel axle 201, and then transmitted to the eccentric shaft 202 through the box body 203, thereby ensuring the stability of the eccentric shaft 202 during high-speed rotation, which is conducive to efficient straightening of the thermocouple wire.

[0049] Furthermore, if Figure 1 As shown, a through slot 101 is provided on the top of the frame 1 , and the through slot 101 is provided corresponding to the box body 203 ; the area of ​​the through slot 101 is larger than the area of ​​the box body 203 .

[0050] Specifically, since a through slot 101 is provided on the top of the frame 1, the through slot 101 is provided corresponding to the box body 203, and the area of ​​the through slot 101 is larger than the area of ​​the box body 203, the box body 203 is not disturbed by the top platform of the frame 1 during high-speed rotation, which can effectively reduce the height of the straightening device 2, simplify the overall structure, reduce the space occupied by the device, and can meet different site layouts and production requirements.

[0051] According to an embodiment of the present invention, the rotation speed of the motor 4 is 2800RPM-3200RPM.

[0052] Specifically, since the rotation speed of the motor 4 is 2800RPM-3200RPM, it can drive the straightening device 2 to rotate at high speed and generate centrifugal force, which can effectively eliminate or reduce the internal stress of the thermocouple wire, so that the thermocouple wire is continuously swung by high-speed centrifugation, thereby achieving the purpose of efficient straightening.

[0053] The second aspect of the present invention discloses an operating method of a thermocouple wire straightening device, comprising the following steps:

[0054] S1, insert the thermocouple wire through the shaft hole of the wheel shaft 201, and pass through the shaft hole of the eccentric shaft 202, and finally pass the thermocouple wire out from the output shaft hole of the bearing seat 3;

[0055] S2, start the motor 4, the motor 4 rotates at high speed, drives the wheel shaft 201 to rotate at high speed through the belt 401, and drives the eccentric shaft 202, the box body 203 and the output shaft of the bearing seat 3 to rotate at high speed, thereby generating centrifugal force.

[0056] S3. The thermocouple wire is continuously subjected to high-speed centrifugal swing under the high-speed rotation of the eccentric shaft 202, thereby eliminating or reducing the internal stress of the thermocouple wire.

[0057] Specifically, the operation method of the thermocouple wire straightening device can efficiently perform centrifugal force straightening on the thermocouple wire, effectively improving the uniform straightening effect and flexible adaptability of the thermocouple wire, shortening the straightening time, reducing human intervention, and improving production efficiency and product quality; at the same time, the device can perform centrifugal force straightening on different small-diameter metal wire materials, enhancing the versatility and practicality of the device.

[0058] The third aspect of the present invention discloses the application of a thermocouple wire straightening device in the field of straightening small-diameter metal wire materials.

[0059] The thermocouple wire straightening device can efficiently straighten small-diameter metal wires, thereby improving the applicability and versatility of the device, ensuring that different types of small-diameter metal wires meet their performance requirements after straightening, and improving the quality and stability of the products after straightening. In addition, the device can meet the needs of one-time straightening of small-diameter metal wire materials without the need for multiple straightening operations, thereby avoiding the possibility of residual bending of the metal wire in traditional straightening methods, which may lead to re-bending and deformation, and effectively improving the straightening efficiency of small-diameter metal wire materials.

[0060] Furthermore, the diameter of the small-diameter metal wire material ranges from 0.5 mm to 3 mm.

[0061] Specifically, since the diameter range of the small-diameter metal wire material is 0.5mm-3mm, the metal wire material in this diameter range can be straightened quickly and efficiently, shortening the straightening time, improving the straightening efficiency, and meeting the straightening needs of large quantities of metal wire materials.
