Utility Model Content

[0003] The purpose of this utility model is to provide a wire feeding and changing device for a wire EDM machine and a wire EDM machine. By installing the first wire feeding mechanism and the second wire feeding mechanism on the wire changing moving mechanism, the first wire feeding mechanism can directly feed the first electrode wire into the third wire feeding mechanism, which solves the problem of the complicated coordination when replacing the second electrode wire with the first electrode wire in the prior art.

[0004] The technical solution of this utility model is as follows: the wire changing and feeding device includes: a vertical moving mechanism, a wire changing moving mechanism, a first wire feeding mechanism, a second wire feeding mechanism and a third wire feeding mechanism.

[0005] The vertical moving mechanism is mounted on the frame of the wire cutting machine, the wire changing moving mechanism and the third wire feeding mechanism are mounted on the vertical moving mechanism, and the first wire feeding mechanism and the second wire feeding mechanism are mounted on the wire changing moving mechanism.

[0015] In another embodiment, the first wire feeding mechanism and the second wire feeding mechanism are respectively mounted on two wire changing moving mechanisms.

[0016] In a further embodiment, the wire-changing moving mechanism is a linear motion mechanism, which is used to move the first wire feeding mechanism and the second wire feeding mechanism in a straight line.

[0017] In a further embodiment, the linear motion mechanism includes one of a linear motor, a lead screw mechanism, and a rack and pinion mechanism.

[0018] In a further embodiment, the wire-changing moving mechanism is a rotary motion mechanism, which is used to rotate the first wire feeding mechanism and the second wire feeding mechanism about a rotation axis.

[0019] In a further embodiment, the rotary motion mechanism includes one of a rotary motor, a gear mechanism, an eccentric rotary mechanism, and a worm gear mechanism.

[0020] A wire cutting machine includes: a frame, a first wire source device, a second wire source device, a tensioning device, a wire threading device, a wire clamping device, a first wire conveying device, and a wire changing and feeding device.

[0021] The first filament source device, the second filament source device, the tensioning device, the filament changing and feeding device, and the filament threading device are mounted on the frame;

[0022] The wire clamping device is installed on the second wire source device, the wire threading device is located between the wire changing and feeding device and the second wire source device, and the first wire conveying device is located on the side of the second wire source device away from the wire threading device.

[0023] The first wire source device is used to carry the first electrode wire, so that the first electrode wire extends from the first wire source device to the wire changing and feeding device.

[0024] The second wire source device is used to carry the second electrode wire, so that the second electrode wire extends from the second wire source device through the tensioning device to the wire changing and feeding device.

[0025] The wire changing and feeding device is used to transport the first electrode wire or the second electrode wire into the wire threading device.

[0026] The beneficial effects of this utility model are as follows: By installing both the first wire feeding mechanism and the second wire feeding mechanism on the wire changing moving mechanism, the wire changing moving mechanism can drive the first wire feeding mechanism and the second wire feeding mechanism to move, so that the first wire feeding mechanism can directly feed the first electrode wire into the third wire feeding mechanism without passing through the wire changing guide, thus solving the problem of the relatively complicated coordination when replacing the second electrode wire with the first electrode wire in the prior art.

[0049] The wire changing and feeding device 1 is used to transport the first electrode wire or the second electrode wire into the wire threading device 6.

[0053] Linear motion mechanisms include one of the following: linear motors, lead screw mechanisms, and rack and pinion mechanisms, such as... Figure 1 and 2 The linear motion mechanism shown includes a lead screw mechanism.

[0054] The linear motion mechanism can be extended along the longitudinal direction, or as follows: Figure 1 and 2 The device can be set to extend horizontally as shown, or it can be set to extend diagonally; it is not limited to this.

The position control points of the first electrode wire and the second electrode wire can be increased by adding guide wheels, and the longitudinal spacing of the first electrode wire and the second electrode wire can be adjusted by adjusting the longitudinal spacing of the guide wheels to avoid the first electrode wire and the second electrode wire crossing during the movement of the first wire feeding mechanism 13 and the second wire feeding mechanism 14. It is not limited to this.
