Problems solved by technology

[0003] The wire electric discharge machine mainly includes a wire feeding mechanism, a wire frame and a workbench (X, Y axis) for moving the workpiece. The wire feeding mechanism and the wire frame of the prior art electric discharge cutting machine are separately arranged. Each occupies a certain space, so firstly the overall volume is relatively large; secondly, because the operator needs to operate on the operation box at the position of the wire frame for normal operation, and when the electrode wire needs to be replaced, it needs to be operated at the wire transport mechanism. Therefore, the operator needs to move between two areas, and the operation is not very convenient

Embodiment 1

[0040] A wire electric discharge machine, comprising a controller, a wire frame 1, an upper wire arm 4, a lower wire arm 5, a wire transport mechanism, a reciprocating operation mechanism and an automatic tensioning mechanism 32, wherein:

[0041] The controller is a commonly used controller in the prior art WEDM, which is used to control the work of each mechanism, so it is not detailed here;

[0042] The upper wire arm 4 and the lower wire arm 5 are arranged on one side of the wire frame 1, an upper guide wheel 66 is arranged on the upper wire arm 4, and a lower guide wheel 67 is arranged on the lower wire arm 5;

[0043] The wire frame 1 is divided into three parts in the vertical direction, which are divided into a lower part, a middle part and an upper part. The lower part is equipped with a motor 3 and a second fixed guide wheel 65; The cover, the upper part is equipped with an automatic tensioning mechanism 32 and a first fixed guide wheel 64, and the motor 3 and the wi...

Embodiment 2

[0050] The difference from the first embodiment is that the reciprocating operation mechanism in the second embodiment also includes a tensioning assembly for tensioning the belt 9, and the tensioning assembly includes a tensioning bracket 12, a tensioning wheel 14 and a tensioning spring 13, and the tensioning The bracket 12 is provided with a chute, the tensioning bracket 12 is slidably connected to the middle side of the wire frame 1 through the locking piece, the tensioning wheel 14 is rotatably connected to the tensioning bracket 12, and the tensioning wheel 14 is in contact with the belt 9, A tensioning spring 13 is also arranged between the bottom of the tensioning bracket 12 and the wire rack 1 , so that the belt 9 can be kept in a tensioned state by the tensioning force provided by the tensioning spring 13 .

Embodiment 3

[0052] The difference from the first embodiment is that in the third embodiment, the automatic tensioning mechanism 32 further includes a roller bracket 43 , a first roller 44 and a second roller 45 , and the first roller 44 and the second roller 45 are both rotatably connected to the roller bracket 43 . and the roller bracket 43 passes through the wire frame 1, the first roller 44 is located on one side of the wire frame 1, the second roller 45 is located on the other side of the wire frame 1, one end of the wire rope 38 is fixed on the linear bearing seat 37, and the other end of the wire rope 38 After passing around the first roller 44 and the second roller 45 in sequence, it is fixed on the wire disc 39 . In this way, the wire disc 39 and the rotating shaft 41 can be installed on the back of the wire frame 1, which greatly reduces the overall installation area.

Description

technical field [0001] The invention relates to the technical field of electric spark wire cutting, in particular to a wire electric spark cutting machine. Background technique [0002] During wire EDM, the wire electrode and the workpiece are connected to the positive and negative electrodes of the pulse power supply respectively, and the workpiece material is eroded by the instantaneous high temperature generated by the pulsed EDM discharge between the workpiece and the wire electrode. [0003] The wire EDM mainly includes a wire transport mechanism, a wire rack and a worktable (X, Y axis) for moving the workpiece. The wire transport mechanism and the wire rack of the prior art EDM cutting machine are set separately. Each occupies a certain space, so first of all, the overall occupied volume is large; secondly, because the operator needs to operate on the operation box at the wire frame position for normal operation, and when the electrode wire needs to be replaced, it nee...
