[0001] The application belongs to the technical field of wire cut electrical discharge machining equipment, and particularly relates to a semi-automatic middle wire feeding guiding and conducting device. BACKGROUND

[0002] The reciprocating wire cut electrical discharge machine (commonly known as middle wire feeding) is a unique type of electrical discharge machining machine in China, which can process various precision molds, can process conductive metal workpieces with large thickness, taper and upper and lower special shapes, and is one of the most widely used machines in China at present, and has an irreplaceable advantage in the mold manufacturing field. Although the current reciprocating wire cut electrical discharge machine in China has the multiple cutting mode like the foreign slow wire feeding machine, there are still defects in the conducting and wire feeding under the first knife high-speed wire feeding (8-12 meters per second) cutting state, and the application will improve such problems and greatly improve the cutting efficiency and stability.

[0003] In the process of implementing the application, the inventor found that there are at least the following problems in the technology: Because the conventional reciprocating wire cut electrical discharge machine is prone to slight shaking which is difficult to distinguish with naked eye during high-speed wire feeding cutting, the final machining precision mold causes uneven cutting surface, the roughness and precision are affected, thereby causing the problem that the conventional wire cut electrical discharge machine has uneven cutting surface of the target.

[0004] Therefore, we propose a semi-automatic middle wire feeding guiding and conducting device to solve the above problems. SUMMARY

[0005] The purpose of the application is to solve the problem of uneven cutting surface of the target of the conventional wire cut electrical discharge machine in the prior art, and a semi-automatic middle wire feeding guiding and conducting device is proposed.

[0006] In order to achieve the above purpose, the application adopts the following technical scheme: a semi-automatic middle wire feeding guiding and conducting device, comprising a connecting seat, a conducting seat fixedly connected to the side end of the connecting seat, an anti-shaking main body fixedly installed at the lower end of the conducting seat, the anti-shaking main body comprising a first consumption sleeve, a second consumption sleeve, a guide sleeve and a threading sleeve, the first consumption sleeve slidingly penetrating the second consumption sleeve, the lower end of the second consumption sleeve being in sliding contact with the guide sleeve, the upper part of the second consumption sleeve slidingly penetrating the conducting seat, the upper part of the guide sleeve being fixedly connected with the conducting seat, and the threading sleeve being slidingly installed on the inner wall of the guide sleeve.

[0007] Preferably, the anti-shaking main body further comprises a retaining ring, the lower end of the retaining ring being fixedly connected to the upper end of the first consumption sleeve, and the retaining ring and the first consumption sleeve being an integral structure.

[0008] Preferably, the upper end of the second consumption sleeve is provided with a plurality of drainage holes, and the side space of the second consumption sleeve is connected with the internal space of the conductive seat in a through manner.

[0009] Preferably, the upper end of the guide sleeve is fixedly connected with a flange, and the flange is an integral structure with the guide sleeve, and the flange is fixedly installed at the lower end of the conductive seat by screws.

[0010] Preferably, the conductive seat comprises a water guide seat, the upper end of the guide sleeve is fixedly installed at the lower end of the water guide seat by screws, the second consumption sleeve is in sliding contact with the water guide seat, and the second consumption sleeve is located at the inner side of the water guide seat, and one side end of the water guide seat is fixedly connected with the side end of the connecting seat.

[0013] In summary, the technical effects and advantages of the present application are as follows: 1. The threading sleeve fixes the lower end of the molybdenum wire, and the molybdenum wire is fixed through the first consumption sleeve and another molybdenum wire device of the electric spark wire cutting machine. During work, the shaking of the molybdenum wire acts on the first consumption sleeve, so that the first consumption sleeve acts on the second consumption sleeve, and the second consumption sleeve acts on the guide sleeve at the same time. Meanwhile, the shaking energy is lost by using the molybdenum wire to drive the threading sleeve to vibrate up and down.
