Description

Technical Field

[0001] The utility model relates to the technical field of reactor coil bending, in particular to a reactor coil bending tool. Background Art

[0002] Reactors are mainly used in power systems to limit short-circuit current, reactive power compensation and phase shifting. They are inductive high-voltage electrical appliances. The production process of reactors includes winding, soldering, assembly, varnishing, drying and other processes. When winding, a winding machine is usually used to wind the conductor into a reactor coil, and then the coil is assembled into a reactor. The enameled wire needs to be bent when it is input and output. Bending tooling is required for bending during the production of the reactor coil.

[0003] After searching, the patent with announcement number CN221018419U discloses a reactor wire package bending tool. It includes: a hollow tube, a positioning rod and a fastener. The interior of the hollow tube is used to accommodate the free end of the wire in the wire package; the positioning rod is matched and arranged in the hollow tube, and the end of the positioning rod abuts against the free end of the wire to limit the depth of the wire extending into the hollow tube; the fastener is connected to the hollow tube, and the end of the fastener passes through the hollow tube and abuts against the positioning rod. The utility model is used to solve the problem of laborious and inefficient bending of the inlet and outlet wires in the wire package. The wire inserted into the hollow tube abuts against the positioning rod to determine the insertion length of the wire. At this time, the fastener keeps the positioning rod relatively fixed to the hollow tube. At this time, the wire of the wire package is bent by bending the hollow tube and the positioning rod as a whole. The lever principle is used to be more labor-saving to bend the inlet and outlet wires of the wire package, thereby improving production efficiency.

[0004] The technical solution has the following problems:

[0005] Although the wire can be bent by bending the hollow tube and the positioning rod during use, the wire cannot be fixed during the bending process. When the hollow tube and the positioning rod are bent to bend the wire, the wire is easy to slide in the hollow tube, causing errors. Utility Model Content

[0015] In a possible design, a rubber pad for improving the fixing effect is fixedly provided on the bottom of the clamping plate.

[0016] In a possible design, the fixing plate is made of transparent acrylic material.

[0017] In the present application, when in use, first pull the positioning rod to make the positioning rod slide in the hollow tube, adjust the position of the positioning rod in the hollow tube according to the length of the wire, and observe it according to the scale line, then rotate the first horn bolt to make the bottom end of the first horn bolt close to the bottom inner wall of the groove of the positioning rod, so as to fix the positioning rod, and then the hollow tube is sleeved on the wire of the wire package, and the wire inserted into the hollow tube abuts against the positioning rod to determine the insertion length of the wire, and then rotate the second horn bolt to make the second horn bolt threadedly connected to the other end of the hollow tube, and drive the arc-shaped clamp through the rotating action. The plate is brought close to the conductor, and the clamp is rotated to make it fit tightly with the conductor. The conductor is fixed between the hollow tube and the clamp by further tightening the second horn bolt, so that the conductor can be fixed. The guide rod slides in the round hole of the hollow tube to ensure that the clamp can move stably and limit the position when fixing the conductor without rotation. Then the personnel can hold the first handle on the hollow tube and the positioning rod, and bend the wire package conductor by prying the hollow tube and the positioning rod as a whole. The inlet and outlet conductors of the wire package can be bent more labor-savingly through the lever principle, which can effectively improve production efficiency and can be released after bending.
