Description

Technical Field

[0001] The utility model relates to the field of enameled wires, in particular to a stretching and fixing mechanism for enameled wire production. Background Art

[0002] The motor is an indispensable component in today's society. The core of the motor is mostly a rotor wound by enameled wire, because the enameled wire has insulation properties, high temperature resistance, wear resistance, etc. In addition, the enameled wire is not easy to age and has a long service life, so its maintenance cost is relatively low, so the advantages and disadvantages of the manufacturer's enameled wire production are related to the performance of the motor. The production of enameled wire includes wire unwinding, annealing, painting, baking, cooling and wire winding. Among them, in the enameled wire unwinding module, stretching is the most important link. Therefore, during the stretching process of the enameled wire in the stretching device, a stretching fixing mechanism must be used to fix the enameled wire.

[0003] The currently commonly used enameled wire production stretching and fixing mechanism straightens the raw wire of the raw coil through the wire rack and the lead wheel, and then guides the raw wire into the stretching device. After passing through the stretching device, the finished wire is guided into the annealing process through the lead-in wheel.

[0004] This enameled wire production stretching and fixing mechanism has a simple structure, which is convenient for operators to guide the raw wire into the stretching device. However, in the production process, because the raw wire cannot be locked during the guiding process, the raw wire will appear uneven in tension during the stretching process of the stretching device, thereby affecting the elongation, flexibility and thermal shock resistance of the finished wire.

[0008] As an improvement, the moving stick fixing device includes a positioning block located between the inner walls of the U-shaped fixing frame, a sealing cover located at the open end of the U-shaped fixing frame, and a positioning screw passing through the positioning block and the sealing cover, and the positioning screw is connected to the positioning block via a threaded through-hole column.

[0009] As an improvement, the longitudinal fixing device includes an F-type positioning frame and two fixing rollers located between the F-type positioning frames.

[0010] As an improvement, a T-shaped slide groove is provided inside the F-shaped positioning frame, and the fixed roller is located between the T-shaped slide grooves. The fixed roller is connected to the F-shaped positioning frame via a locking nut.

[0011] As an improvement, the T-shaped slide groove and fixed roller, the static roller and U-shaped fixing frame, and the movable roller and positioning block are all connected through bearings, the upper wire rack, the wire guide wheel, the stretching device, the taking-up wheel, the fixing mechanism and the wire guide device are all connected to the workbench through screws, and the U-shaped fixing frame and the sealing cover are connected through a bolt structure.
