[0029] Embodiment 1:

[0030] See Figure 1 - Figure 2, A wire cutting transfer device for narrow spaces, comprising: a first transfer rack, a second transfer rack, and a wire cutting wire 7. There are 5 groups of first guide wheels 5 provided on the first transfer rack; the first transfer rack is used for sliding connection in the first chute 11 of the workpiece 10 to be processed; the first transfer rack includes a first vertical support 1 and a first horizontal support 2, and the first vertical support 1 and the first horizontal support 2 are perpendicularly connected. The 5 groups of first guide wheels 5 include two first guide wheels 5. One first guide wheel 5 is installed on the outer side of the bottom of the first vertical support 1, and the other first guide wheel 5 is installed at the front end of the first horizontal support 2. The first guide wheel 5 is a V-shaped guide wheel. The V-shaped guide wheel can play a better guiding role for the wire cutting wire 7 and prevent it from slipping out.

[0031] There are 6 groups of second guide wheels 6 provided on the second transfer rack; the second transfer rack is used for sliding connection in the second chute 12 of the workpiece 10 to be processed; the second transfer rack includes a second vertical support 3 and a second horizontal support 4, and the second vertical support 3 and the second horizontal support 4 are perpendicularly connected. The 6 groups of second guide wheels 6 include two second guide wheels 6. One second guide wheel 6 is installed on the outer side of the bottom of the second vertical support 3, and the other second guide wheel 6 is installed at the front end of the second horizontal support 4. The second guide wheel 6 is a V-shaped guide wheel.

[0032] The wire cutting wire 7 passes through the 5 groups of first guide wheels 5 of the first transfer rack, the interval between the first chute 11 and the second chute 12 of the workpiece 10 to be processed, and then passes through the 6 groups of second guide wheels 6 and exits from the second transfer rack; the wire cutting wire 7 realizes the processing of the interval under the synchronous drive of the first transfer rack and the second transfer rack. The wire cutting wire 7 is a molybdenum wire.

[0033] By manufacturing two groups of L-shaped first transfer racks and second transfer racks with dimensions of 300*350*10 and installing them on the wire cutting wire 7 rack of the DK7780 numerical control, the situation where wire cutting can only move the wire vertically up and down is changed, enabling the molybdenum wire for wire cutting to continuously turn 2 90°, and processing the enclosed space.

[0034] Specifically, in some embodiments, a first vertical step groove is provided on the first vertical support 1, a first horizontal step groove is provided on the first horizontal support 2, the first guide wheel 5 is arranged in the first vertical step groove, and the wire cutting wire 7 passes through the first horizontal step groove. The setting of the first vertical step groove makes the position where the first guide wheel 5 is set not appear very prominent. And the first horizontal step groove enables the wire cutting wire 7 to pass through it.

[0035] In some embodiments, a second vertical step groove is provided on the second vertical support 3, a second horizontal step groove is provided on the second horizontal support 4, the second guide wheel 6 is arranged in the second vertical step groove, and the wire cutting wire 7 passes through the second horizontal step groove.

[0036] The provision of the second vertical step groove ensures that the position where the second guide wheel 6 is set does not appear obtrusive. The second horizontal step groove enables the wire cutting wire 7 to pass through it.

[0037] The device of the present utility model solves the processing problem of wire cutting in a narrow space. By designing and manufacturing 2 L-shaped transfer molybdenum wire frames, namely the first transfer frame and the second transfer frame, two V-shaped guide wheels with an outer diameter of 10 mm are respectively installed at the corners and the ends of each transfer frame. One end of the first transfer frame is installed on the wire cutting wire 7 frame, and the upper wire frame movement handwheel is adjusted to move the two L-shaped transfer molybdenum wire frames into the two closed grooves of the workpiece 10, namely the first chute 11 and the second chute 12. The wire is passed through the pre-drilled Ф3 process hole 9. After finding the correct position, electrical discharge machining is carried out. The tolerance of the processed finished product is controlled within 0.02 mm. It should be noted here that the processing wire path program of wire cutting is a continuous Z-shape, and the part to be cut is cut into a shape with a diameter smaller than the Ф3 process hole 9, so that it is convenient to timely take out the cut waste from the Ф3 process hole 9 and make the square hole 8 to be processed.

[0038] The specific usage method is as follows:

[0039] 1). Install the two L-shaped first transfer frames and the second transfer frame on the DK7780 wire frame, and use a dial indicator to align the straightness of the transfer frame in the horizontal and vertical directions.

[0040] 2). Install the workpiece on the DK7780 workbench.

[0041] 3). Shake the wire frame lifting handwheel to adjust the L-shaped transfer frame into the narrow groove of the workpiece without short-circuit contact with the workpiece.

[0042] 4). Use a molybdenum wire hook to pass the molybdenum wire through the wire frame guide wheel, the conductive block, the tensioning wheel, the two groups of V-groove guide wheels on the L-shaped molybdenum wire transfer frame, and the wire-passing hole of the workpiece in sequence from the wire drum.

[0043] 5). Start the molybdenum wire, find the zero position of the workpiece by high-frequency spark collision and then zero the dial.

[0044] 6). Start the program for processing.

[0045] The above is only the preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
