Description

Technical Field

[0001] The utility model belongs to the technical field of foil strip winding in transformer manufacturing industry, and specifically relates to a double-wire electric shearing device. Background Art

[0002] At present, foil coil winding machines (referred to as foil winding machines) are widely used in the dry-type transformer manufacturing industry. The main structural and functional material elements of the foil coil winding machine are foil unwinding, interlayer insulation tape unwinding, end insulation tape tension unwinding, comprehensive winding, foil (or insulation tape) cutting, transformer inlet and outlet busbar argon arc welding (or cold pressure welding, ultrasonic welding), and foil correction. The core mission of this equipment is to "tightly" and "neatly" wind the foil coils for the transformer. Welding and cutting should be regarded as "auxiliary" functions, so the mechanism for "welding" and "cutting" to achieve the two auxiliary functions should be simpler and smaller; "welding" and "cutting" should be near "winding", but the conventional foil winding machine shearing devices on the market are mostly set in the frame behind the winding device (if it is a double-layer foil winding machine, the two sets of shearing devices almost occupy the front half of the frame). When cutting the material, the foil tape should be cut back 2~3 meters, which makes the transformer winding process "regress" and affects the work efficiency and quality. Utility Model Content

[0003] The purpose of the utility model is to provide a double-wire electric shearing device to overcome the above-mentioned technical problems existing in the prior art.

[0004] To this end, the technical solutions provided by this application are as follows:

[0005] A double-wire electric shearing device comprises a control system, a shearing moving mechanism, electric scissors, a slide moving mechanism, a first detection switch and a second detection switch, wherein the slide moving mechanism is symmetrically arranged on both sides of a coil winding machine frame, the shearing moving mechanism is arranged on the slide moving mechanism, the electric scissors are arranged on the shearing moving mechanism, the second detection switch and the first detection switch are arranged on a bracket and are arranged front and back along the feeding direction, the bracket is arranged on the inner side of the shearing moving mechanism on one side, and the shearing moving mechanism, the slide moving mechanism, the first detection switch and the second detection switch are all connected to the control system electrical signal.

[0006] The shearing movement mechanism includes a base, a reduction motor, a wire rope pulley block, a linear guide pair and a scissors fixing seat. The reduction motor, the wire rope pulley block and the guide rails of the linear guide pair are all fixed on the base. The scissors fixing seat is fixed on the slider of the linear guide pair. The electric scissors are arranged on the scissors fixing seat. The guide rails of the guide pair and the slider are slidably connected.

[0007] The slide moving mechanism includes an adapter plate and a slide cylinder. The adapter plate is installed on the coil winding machine frame. The slide cylinder is fixed on the adapter plate. The movable end of the slide cylinder is connected to a cylinder slider. The shear moving mechanism is arranged on the cylinder slider.

[0008] It also includes a slag receiving trough, which is fixed on the base of the shearing movement mechanism.

[0009] The distance between the first detection switch and the second detection switch is 35-45 mm.

[0010] The beneficial effects of the utility model are:

[0011] The double-passing electric shearing device provided by the utility model is based on the method of "cutting according to the drawn line" that has been used in foil coil winding. The electric scissors are installed on the shearing moving mechanism, and the material return is controlled by the control system. When the first detection switch scans the "line", the material return stops, and the slide moving mechanism drives the shearing device to move. When the second detection switch scans the "line", the slide moving mechanism stops, and the shearing moving mechanism drives the electric scissors to move in a straight line to cut the foil strip material according to the line.

[0012] The double-pass electric shearing device has a simple structure, low cost, low maintenance cost, and realizes the automatic shearing of foil strips. The arrangement of the double-pass electric shearing device with "stop" is not limited to the main machine frame, but is preferably closer to the winding main machine, which can greatly shorten the material withdrawal distance and reduce the impact of material withdrawal on the winding quality.

[0019] Example 1

[0020] This embodiment provides a double-wire electric shearing device, such as Figure 1 As shown, it includes a control system, a shearing moving mechanism 1, an electric scissors 2, a slide moving mechanism 3, a first detection switch 4 and a second detection switch 5. The slide moving mechanism 3 is symmetrically arranged on both sides of the coil winding machine frame, the shearing moving mechanism 1 is arranged on the slide moving mechanism 3, the electric scissors 2 is arranged on the shearing moving mechanism 1, the second detection switch 5 and the first detection switch 4 are arranged on a bracket 7, and are arranged front and back along the feeding direction, the bracket 7 is arranged on the inner side of the shearing moving mechanism 1 on one side, and the shearing moving mechanism 1, the slide moving mechanism 3, the first detection switch 4 and the second detection switch 5 are all connected with the control system electrical signal.

[0021] Steps:

[0022] The method of "cutting according to the drawn line" has been used in foil coil winding. Therefore, first, the foil strip needs to be cut to the drawn line, and then the shear button of the coil winding machine is activated to automatically return the material. When the first detection switch 4 scans the "line", the material return stops, and the control system sends a start signal to the slide moving mechanism 3, thereby driving the shear moving mechanism 1, the first detection switch 4, and the second detection switch 5 to move. When the second detection switch 5 scans the "line", the control system sends a stop signal to the slide moving mechanism 3, and the shear moving mechanism 1 drives the electric scissors 2 to perform the shearing action. After the shearing is completed, the shear moving mechanism 1 and the slide moving mechanism 3 return to the initial position to complete the shearing. Among them, the control system can use a PLC controller.

[0025] Working process:

[0026] The control system sends a signal to the reducer, and the reducer rotates to drive the wire rope pulley group to drive, so that the slider of the linear guide pair moves along the guide rail of the linear guide pair, thereby guiding the scissor fixing seat, realizing the movement of the electric scissors 2, and cutting the foil strip.
