Description

Coaxial superconducting wire winding machine

technical field

The utility model relates to a wire winding machine, in particular to a coaxial superconducting wire winding machine for heavy ion accelerators.

Background technique

Due to the special requirements of the working environment for superconducting wires used in heavy ion accelerators, the manufacturing process of the cables is different from that of ordinary power cables. The distance is controllable and stable and precise, the winding is tight and not easy to break, and the production efficiency is high. Due to the particularity of processed products, there must be special requirements for its processing equipment. However, the winding machines currently available in the market are all made of winding strips or light materials. Generally, there are no special requirements for the length of the material and can be continuously Joints and pay-off reels are generally arranged in a tangential arrangement. When rotating, the moment of inertia is large, and it is easy to break the wire. It is impossible to realize long-length continuous pay-off. Since the superconducting wire used in the heavy ion accelerator is not allowed to be broken during the production process, so Tangential layout cannot meet the process requirements. As shown in Figure 3, the prior art superconducting wire winding machine for heavy ion accelerators, the pay-off reel 5 is arranged tangentially with the axis of the winding machine mechanism, and the pay-off reel 5 rotates around the cable together with the winding arm 6 during work. The moment of inertia is large, it is easy to break the wire, it cannot run at high speed, and the production efficiency is not high; and because the size of the pay-off reel cannot be too large, the length of the superconducting wire is limited, and it cannot adapt to the production of large-length superconducting cables without joints. requirements.

Detailed ways

Below, the coaxial superconducting wire winding machine of the present invention will be further described in detail in conjunction with the accompanying drawings.

The coaxial superconducting wire winding machine for heavy ion accelerators shown in Figure 1 and Figure 2 includes a support 2 and a hollow main shaft 3 on it. The hollow main shaft 3 is driven by a motor 1 through a pulley, and on the hollow main shaft 3 A balance arm 4 is provided through a bearing, and one end of the balance arm 4 is provided with a winding arm 6 parallel to the hollow main shaft 3. The winding arm 6 is provided with a guide wheel, and the position corresponding to the winding arm 6 on the hollow main shaft 3 is set by a bearing. There is a pay-off reel 5; the end of the hollow main shaft 3 is provided with a wire passing die 7, and the end of the wire passing die 7 is provided with a tightening nut 8, and the pay-off reel 5 is fixed on the main shaft 3 by a clamping device, clamped The device is a thimble head 9 installed on the bearing of the corresponding pay-off reel, and a damping disc 10 is arranged between the balance arm 4 and the clamping device.

Special coaxial superconducting wire winding machine The superconducting wire pay-off reel and the winding machine mechanism are coaxially arranged. The winding machine mechanism consists of a synchronous pulley, winding arm 6, guide wheel, and the clamping device is installed on the hollow main shaft through bearings. 3, the synchronous pulley and the winding arm 6 are connected by a key and then sleeved on the hollow main shaft bearing. When working, the traction device pulls the core of the superconducting cable through the central shaft hole of the winding machine at a constant speed, and at the same time, the winding frequency conversion speed regulating motor drives the winding mechanism to rotate at a certain speed _n1 through the synchronous pulley, and at the same time, the winding arm 6 drives the superconducting cable through the damping disc. The wire pay-off reel 5 rotates, and because the winding motion also additionally forms the superconducting wire pay-off reel 5 pay-off motion n, so the superconducting wire pay-off reel 5 rotating speed n ₂ is by the revolution speed n ₁ synchronous with the winding mechanism (by winding independent control of frequency converter) and the self-speed n of winding and pay-off forms the relationship of n ₂ =n ₁ +n. While the winding mechanism is running, it drives the superconducting wire pay-off reel 5 and the winding arm 6 to rotate around the superconducting cable core in the same direction, and the superconducting wire is tightly wound on the superconducting cable core through the winding arm 6 guide wheel. At the same time, the traction frequency conversion speed regulation system drives the wound cores to advance evenly at a certain speed, forming the winding pitch and production speed required by the process. Since the superconducting wire pay-off reel 5 is set on the winding arm 6 shaft, it can not only effectively eliminate the inertia and friction of the superconducting wire pay-off reel, but also meet the speed difference between the winding arm 6 and the winding arm 6 due to the pay-off movement. Require. So as to meet the production process requirements very well.
