The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] The utility model is described in detail below with reference to the accompanying drawings.

[0037] If Figure 1 As shown, a corrugated pipe wire cutting die of the utility model is characterized in that it includes: a columnar member 5, the side of the columnar member 5 has two fixed planes 53, and the two fixed planes 53 are arranged in parallel; the two ends of the columnar member 5 are respectively provided with a front through hole 51 and a rear through hole 52, the diameter of the front through hole 51 is larger than the diameter of the corrugated pipe 6, and the diameter of the rear through hole 52 is smaller than the diameter of the corrugated pipe 6; the fixed planes 53 are each provided with a strip slit 50, one end of the strip slit 50 is connected to the front through hole 51, and the other end is located within the fixed plane 53.

[0038] The utility model specifically cuts the bellows 6 into two halves along the axis by wire cutting, and the two halves are used for waveform detection and half of the bellows 6 is retained as a sample, which is used for comparison and identification of the quality of subsequent reprocessed products and long-term quality management and tracing as a basis.

[0039] Furthermore, by classifying high-reliability bellows 6 products and establishing a parameter table, bellows 6 with the same outer diameter can be combined, and the same size of bellows wire cutting mold can be used; it can reduce the reinvestment of mold costs and ensure the production and processing cycle, thereby reducing manufacturing costs.

[0040] Example 1

[0041] This embodiment provides a corrugated pipe wire cutting die, comprising: a columnar member 5, the side of the columnar member 5 has two fixed planes 53, and the two fixed planes 53 are arranged in parallel. The two ends of the columnar member 5 are respectively provided with a front through hole 51 and a rear through hole 52, the diameter of the front through hole 51 is larger than the diameter of the corrugated pipe 6, and the diameter of the rear through hole 52 is smaller than the diameter of the corrugated pipe 6. The corrugated pipe 6 is placed through the front through hole 51 and prevented from slipping out of the columnar member 5 through the rear through hole 52.

[0042] A strip-shaped slit 50 is provided on each of the fixing planes 53 , one end of each of the strip-shaped slits 50 is connected to the front through hole 51 , and the other end is located inside the fixing plane 53 .

[0043] Specifically, the columnar member 5 is a cylinder. The front through hole 51 and the rear through hole 52 are both circular through holes. The strip slits 50 on the two fixing planes 53 are located in the same plane, which are used to provide space for wire cutting.

[0044] Example 2

[0045] This embodiment provides a corrugated pipe wire cutting device, including a corrugated pipe wire cutting mold and a work surface 7, and the columnar member 5 is arranged on the work surface 7.

[0046] The top of the work surface 7 has a first step 71 and a second step 72. A screw assembly is arranged on the second step 72, a pressing block 2 is arranged on the screw assembly, and the columnar member 5 is arranged on the first step 71.

[0047] Optionally, the screw assembly includes a screw 4 and a gasket 3 sleeved on the screw 4.

[0048] Specifically, the pressing block 2 has a strip-shaped through hole, and the pressing block 2 is mounted on the screw rod 4. The screw rod 4 is fixed on the second step 72.

[0049] Specifically, the width of the first step 71 is smaller than the vertical distance between the end of the strip slit 50 away from the front through hole 51 and the rear through hole 52, so as to avoid damage to the work surface 7 during cutting.

[0050] The bellows 6 is an elastic part. When cutting and sectioning by wire, the bellows 6 needs to be fixed. When the bellows 6 is directly pressed by the pressing block 2, the pressing force will damage the appearance of the bellows 6. First, the pressing force affects the original state of the half sample of the bellows 6. Second, the half sample that is damaged cannot be retained as a sample. Third, during the sectioning process, the local deformation of the cut bellows 6 seriously affects the wire speed of the wire cutting. Fourth, the deformed part of the bellows 6 will cause wire clamping, which often breaks the wire, not only affecting the work efficiency, but also posing a safety hazard.

[0051] When the corrugated pipe wire cutting device of the utility model is used, the following steps are included:

[0052] Put the bellows 6 into the columnar member 5 through the front through hole 51, place the columnar member 5 on the first step 71, fix the screw 4 on the second step 72, install the pressing block 2 on the screw 4 through the strip through hole, and fix the columnar member 5 through the pressing block 2 on the screw 4. Turn on the wire cutting device 1 to cut the bellows 6 along the strip seam 50 with the wire 8.

[0053] By placing the corrugated pipe 6 into the cylindrical part 5, since the cutting of the corrugated pipe 6 is along the axis, the cutting advancing direction can relatively fix the corrugated pipe 6 in the axial direction. The radially deformed part of the corrugated pipe 6 that has been cut during the wire electrical discharge machining relatively fixes the corrugated pipe 6 in the cylindrical part 5. The corrugated pipe 6 is placed horizontally during cutting, and the upper and lower waveforms are processed simultaneously. According to the principle of three points determining a plane, rotation will not occur. On the other hand, due to the limitation of the aperture size, the relative deformation amount of the cut part of the corrugated pipe 6 is limited by the clearance between the aperture size of the cylindrical part 5 and the outer diameter size of the corrugated pipe 6, which can reduce the influence on the cutting wire 8, avoid the phenomenon of wire clamping, and the cutting efficiency of the sample will not be affected, and it is relatively safe to avoid the unsafe hidden danger caused by wire breakage.

[0054] In the above embodiments, the equipment components involved are all conventional equipment components without special instructions. The structural setting methods, working methods or control methods involved are all conventional setting methods, working methods or control methods in this field without special instructions.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
