Wire guide mechanism and medium-speed wire cutting machine comprising same

Abstract

The invention provides a wire guide mechanism which comprises a wire guide nozzle body. A first open groove and a second open groove which communicate with each other are formed in the wire guide nozzle body, a second bearing is embedded in the top wall of a first U-shaped sliding plate, a first mounting rod is fixedly sleeved with a first guide cylinder, and a first cleaning brush is fixedly arranged on the first mounting plate. An operation frame is embedded in the side wall, opposite to the first U-shaped sliding plate, of the wire guide nozzle body, a spring is arranged in a cavity of the operation frame, the second guide cylinder is arranged between the top wall and the bottom wall of a second U-shaped sliding plate, and a second cleaning brush is fixedly arranged on a second mounting plate. According to the wire guide mechanism and the medium-speed wire cutting machine comprising the same, wire electrodes of different thickness specifications can be stably guided, gaps generated after the guide cylinders are abraded by the wire electrodes can be made up in real time, use is more convenient, and the first guide cylinder and the second guide cylinder can be used repeatedly and are more durable.

Description

technical field [0001] The invention relates to the technical field of wire cutting machine tools, in particular to a wire guide mechanism and an intermediate wire cutting machine including the mechanism. Background technique [0002] In the prior art, a diamond guide wire with the application number "201720042896.9" includes a guide wire body; the guide wire body is mainly composed of a jacket, a diamond guide wire area and a ceramic wire threading guide section; the guide wire body There is a mold core on the right side; a sintered body is set on the outside of the mold core, and the mold core is provided with a compression area, a diamond guide wire area, a ceramic wire threading guide section and an exit area in sequence from left to right; the diamond guide wire area is provided with a sizing The right side of the guide wire body is fixedly connected to the limit area; the upper and lower inner walls of the limit area are fixedly connected to the limit piece, and the li...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device can only adapt to one kind of wire electrode thickness. Under complex processing conditions, if it is necessary to use multiple electrode wires for processing It is necessary to prepare multiple guide wire devices for replacement, and the operation is cumbersome; 2. For the same electrode wire, after a long time of use, the guide device of the electrode wire will be worn out, which will cause the electrode wire to shift and cause channeling. Vibration or vibration may even cause the electrode wire to break, and th
