Description

Technical Field

[0001] The present invention relates to the technical field of wire electrical discharge machining, and particularly to a wire electrical discharge cutting device capable of precisely adjusting and positioning. Background Art

[0002] A wire electrical discharge cutting machine is a numerically controlled machining device that uses the principle of electrical discharge machining to cut metal materials. It uses a moving thin metal wire (usually molybdenum wire or copper wire) as an electrode, and applies a pulsed voltage between the electrode wire and the workpiece. When the gap between the two reaches a certain degree, the pulsed voltage will cause the working fluid medium to be ionized and broken down, forming an instantaneous spark discharge. Under the action of high temperature and high pressure, the metal material on the surface of the workpiece is melted and vaporized, and thus eroded, realizing the cutting of the workpiece.

[0003] The invention with the publication number CN111347111A discloses a wire electrical discharge cutting machine. The key points of its technical solution are: a wire electrical discharge cutting machine, including a workpiece mounting seat for mounting the workpiece, a base, a sliding seat horizontally slidably connected to the base, and a cutting wire provided on the sliding seat for cutting the workpiece. The sliding seat is provided with a driving mechanism for driving the cutting wire to move and realizing the cutting of the workpiece, and an inclined cutting mechanism for making the cutting wire in an inclined state and realizing inclined cutting. It realizes the inclination of the cutting wire in the space range and inclined cutting of the workpiece, and effectively avoids the problem of equipment wear caused by the hard pulling of the cutting wire.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to the attached Figure 1-12 , and the following technical solutions are provided in this application.

[0038] When the processing wire 13 passes through the horizontal movable arm 2, it is located at the center inside the horizontal movable arm 2. Before reaching the inclined rotating head 3 and lapping with the second carding wheel 6, it is guided by the first carding wheel 5. When the inclined rotating head 3 rotates, the processing wire 13 is at the central level at the rotational joint of the horizontal movable arm 2 and the inclined rotating head 3, without affecting the rotational adjustment of the inclined rotating head 3. The rotational adjustment of the inclined rotating head 3 can be accurately adjusted by a stepping motor cooperating with a reducer;

A relief hole 32 is vertically penetrated through on the side of the wire guiding mounting slide 9 away from the sliding control screw tube 20. When the wire guiding mounting slide 9 abuts against one side of the sliding support 8 close to the sliding control screw tube 20, the relief hole 32 is correspondingly arranged with the laser positioning module 14. The control screw sleeve 22 can be electrically controlled by a servo motor. Through the relative control of the sliding control screw tube 20 and the control screw sleeve 22, the wire guiding mounting slide 9 stably slides horizontally inside the sliding support 8.

[0042] The positioning and calibration component is set so that when it is necessary to calibrate and position the processing metal wire 13 in the working area, it can be quickly adjusted.

The laser positioning module 14 is horizontally placed in the multi-plane high-transmittance protective cover 15. The multi-plane high-transmittance protective cover 15 can be rotatably arranged in the inner cavity 4. The laser positioning module 14 remains stationary in the multi-plane high-transmittance protective cover 15. When the multi-plane high-transmittance protective cover 15 rotates, the laser positioning module 14 remains stationary. The inclined rotating heads 3 of the two horizontally movable arms 2 are both provided with laser positioning modules 14 with multi-plane high-transmittance protective covers 15. Whether it is needed When the processing metal wire 13 is in a vertical posture or an inclined posture, the guide wire mounting slide 9 is moved and controlled by the sliding control screw tube 20 so that the clearance hole 32 corresponds to the laser positioning module 14. At this time, when the two laser positioning modules 14 correspond to each other, it is precisely positioned. After positioning, the guide wire mounting slide 9 can be pushed to its original position. When the position of the guide wire nozzle 12 needs to be calibrated, before the processing metal wire 13 passes through the guide wire nozzle 12, the light beam of the laser positioning module 14 passes through the guide wire nozzle 12 for precise positioning as a reference. The operation is simple and convenient. During the processing, when it is necessary to adjust the taper cutting of the processing metal wire 13, it can be adjusted directly and quickly.
