Description

TECHNICAL FIELD

[0002] Superconducting materials are widely used in medical treatment, transportation, aerospace, power electronics, high-energy physics and national defense and other fields. At present, NbTi and Nb3Sn superconducting wires are relatively mature superconducting products in terms of processing technology and application level.

[0003] High-copper-ratio NbTi / Cu superconducting wire (wire in channel, superconducting wire inlay) has the advantages of low cost, high stability of the prepared magnet and the like, and is one of the main products of high-copper-ratio superconducting wire, and is widely used in superconducting magnets of 3T or less magnetic resonance imaging (MRI) systems.

[0004] Oxygen-free copper channel, as one of the important raw materials in the preparation process of WIC superconducting wire, the stability of its quality is crucial to the inlaying process. The whole preparation process of WIC superconducting wire includes ultrasonic cleaning of copper channel / round wire, soldering, drying, inlaying, online detection and braiding insulation. The purpose of soldering is to remove the oxide layer on the surface of the copper channel by chemical method to ensure the quality of the inlaid copper channel and superconducting wire. However, the soldering agent used in the current WIC process is acidic and has strong acidity. Long-term use of acid gas volatilization is serious, which causes serious corrosion of WIC process equipment, especially the stability of precision instruments, instrument circuit boards and electrical cabinet components. The back of the copper channel is more seriously oxidized, showing black marks and black spots. The copper channel with black marks and black spots cannot reduce the acidity of the soldering agent during use, so as to ensure the corrosion of precision instruments caused by acid gas volatilization.

[0054] Embodiment 1,

[0055] Firstly, the polishing wheel 32 is installed, and the position of the polishing wheel 32 is determined.

[0056] When installing the polishing wheel 32, the polishing wheel 32 is connected to the driving end of the high-speed polishing motor 31 through the clamping head, and then the distance between the side of the polishing wheel 32 close to the high-speed polishing motor 31 and the end face of the clamping head is determined to be 6±1 mm by a steel ruler; at the same time, the use of the polishing wheel 32 is also checked to ensure that the one-side wear of the polishing wheel 32 is less than 15 mm, and if the one-side wear of the polishing wheel 32 is equal to or greater than 15 mm, a new polishing wheel 32 needs to be replaced. The polishing execution mechanism 3 includes three groups of high-speed polishing motors 31, and the highest speed can reach 24000 r / min, which can be adjusted by a frequency converter during operation; the polishing wheel 32 is made of scouring pad material, has a diameter of φ50 mm and a length of 50 mm, is fixed on the driving end of the high-speed polishing motor 31 through the clamping head, and can be disassembled and assembled through an open wrench. When replacing a new polishing wheel 32 each time, the position of the polishing wheel 32 needs to be determined after the polishing wheel 32 is installed.

[0057] Then, the height of the installation support 1 and the guide roller pressing mechanism 5 is adjusted.

[0058] When adjusting the height of the mounting bracket 1, the height of the foot cup 12 at the four corners of the bottom of the mounting bracket 1 is adjusted until the upper surface of the polishing wheel 32 is tangent to the bottom of the copper slot line; when adjusting the height of the guide wheel pressing mechanism 5, the guide wheel pressing mechanism 5 is adjusted to the appropriate height by adjusting the hand wheel 514 cooperating with the lead screw 508 until the copper slot line is in the U-shaped groove of the guide wheel 505, the foot cup 12 is locked, the mounting bracket 1 is fixed, and the device is ensured not to shake during operation. The guide wheel pressing mechanism 5 is provided with four groups of guide wheels 505, and the guide wheels 505 are made of U-shaped groove ceramic material to increase wear resistance. In addition, the bearing fixing seat 511 is designed with two groups of deep groove ball bearings, which cooperate with the lead screw 508 and are fixed by a snap spring. The adjusting hand wheel 514 is connected with the lead screw 508 through a top wire and is used to adjust the height of the guide wheel pressing mechanism 5. The height of the mounting bracket 1 and the guide wheel pressing mechanism 5 is only adjusted and fixed when the entire device is installed for the first time in the inlaying process.

[0059] Then start the reciprocating mechanism 4, and confirm whether the copper slot line will slide out of the length range of the polishing wheel 32 during the reciprocating process.

[0060] Start the speed reducer motor 41 by the start / stop button 623 of the control system, so as to drive the reciprocating mechanism 4 to move. The minimum speed of the speed reducer motor 41 can reach 6 r / min, and the speed of the reciprocating movement can be adjusted by the speed regulator during operation. The eccentric piece 43 is designed with a slot, which cooperates with the drive shaft 44 to adjust the reciprocating stroke through the slot, and the stroke range is 42-65 mm. In the specific implementation of the present application, the reciprocating stroke is adjusted to 42 mm. In addition, the one end of the drive shaft 44 is provided with a needle bearing 45 to avoid wear of the drive shaft 44 caused by long-time use. At the same time, when observing and confirming whether the copper slot line will slide out of the length range of the polishing wheel 32 during the reciprocating process, if there is a risk of sliding out, the position of the polishing wheel 32 is re-confirmed until the stroke of the reciprocating mechanism 4 is adjusted to be within the length range of the polishing wheel 32, and the single-side allowance is ensured to be not less than 3 mm.

[0061] Finally, start the polishing execution mechanism 3 to polish the copper slot line.

[0062] When starting the polishing execution mechanism 3 to polish the copper slot line, the speed of the high-speed polishing motor 31 needs to reach 10,000 r / min, and then the polishing of the copper slot line is started. Every 3,000 m of polishing of the copper slot line, the operator adjusts the guide wheel pressing mechanism 5 downward by 1-2 mm through the adjusting hand wheel 514 and locks the high-head hand screw 513, so as to strictly ensure that the upper surface of the polishing wheel 32 is tangent to the bottom of the copper slot line, and the diameter of the polishing wheel 32 after wear is not less than φ20 mm.

[0063] After the polishing is stopped, the operator presses the stop button of the whole device in time to avoid the malfunction of the motors caused by long time operation.

[0064] After the whole device is used for a period of time, the operator needs to clean the copper powder deposited in the drawer 16 of the mounting bracket 1 in time, and after the cleaning, the drawer 16 is put back to the original position, and the dust cleaner is used to clean the copper powder remaining on the surface of the device.

[0065] During the execution, the reciprocating mechanism 4 must be started first, and then the polishing execution mechanism 3 is started to polish the copper slot line after confirming whether the copper slot line will slide out of the length range of the polishing wheel 32 during the reciprocating process.
