Description

Technical Field

[0001] The present invention relates to the technical field of multi-wire cutting, and further to a multi-wire cutting method for a regular hexagonal prism and a multi-wire cutting auxiliary device. Background Art

[0002] In production and experiments, there is a great demand for hexagonal prism components in the fields of crystal materials, ceramic materials, glass materials, plastics, aluminum materials, copper materials and magnetic materials. How to achieve efficient batch processing has always been a major problem in this field.

[0003] The common processing steps of hexagonal prisms are to first cut and grind the material to be cut into the required size and thickness, and then use the inner circle cutting equipment to cut it into diamond prisms in two times with the help of tooling; then clamp the diamond prisms in small batches and cut a 60° edge; then use the grinder to accurately grind the cut edge surface; after turning, cut and grind the other 60° edge of the diamond prism to obtain a small batch of hexagonal prisms.

[0004] Due to the equipment reasons for inner circle cutting, the efficiency of inner circle cutting is low, the dimensional accuracy is poor, the surface roughness value is large, and only prismatic prisms can be cut. At the same time, in order to process the prismatic prism into a hexagonal prism, the two 60° corners of the rhombus prism are cut and ground in small batches with the help of tooling to obtain a hexagonal prism. Therefore, the entire process of the existing hexagonal prism is complicated, requiring at least five clampings, four cuttings, and two grindings. At the same time, due to the limitations of equipment and technology, only small batches can be processed, with low efficiency and large dimensional tolerance after processing.

[0005] Compared with inner circle and single-wire cutting, multi-wire cutting has the advantages of high efficiency, precise processing size, and saving raw materials. How to use high-efficiency multi-wire cutting to achieve batch processing of regular hexagonal prisms is a pain point and difficulty in this field. Summary of the invention

[0043] refer to Figure 1 and Figure 3 The present invention provides a multi-wire cutting method for a regular hexagonal prism, comprising: installing a positioning substrate 2 on a cutting base plate 1; processing three card slots 31 with the same center on the cutting substrate 3, the angle between adjacent card slots 31 is 60°, and the card slots 31 match the positioning substrate 2; installing a cutting pad 4 on the front of the cutting substrate 3, and then installing a material 5 to be cut on the side of the cutting pad 4 away from the cutting substrate 3; respectively assembling the positioning substrate 2 in the three card slots 31 of the cutting substrate 3, and performing three multi-wire cuttings on the material 5 to be cut by a multi-wire cutting device.

[0044] In this embodiment, the positioning substrate 2 is matched with the three slots 31 of the cutting substrate 3 respectively, and a large number of regular hexagonal prisms can be obtained after multi-wire cutting is performed on the material 5 to be cut three times, thereby solving the technical difficulties of multi-wire cutting of regular hexagonal prisms, improving the efficiency and precision of batch processing of regular hexagonal prisms, and reducing processing costs.

[0045] Specifically, a positioning substrate 2 is installed in the middle of the cutting substrate 3, and the width direction of the positioning substrate 2 is parallel to the multi-wire cutting wire net. The width and height of the positioning substrate 2 are not less than 5mm. The positioning substrate 2 can be aluminum, copper or other materials with a certain width and length, and is used as a positioning reference. The cutting substrate 3 can be round, square or other shapes, and is an auxiliary material for cutting, such as glass, graphite, ceramic, plastic and other materials. The width direction of the positioning substrate 2 is parallel to the cutting surface of the multi-wire cutting equipment. The multi-wire cutting equipment is used to perform multi-wire cutting on the positioning substrate 22 to remove the end skin of the positioning substrate 2. Then, three card slots 31 with a mutual angle of 60° are processed at the center of the back of the cutting substrate 3. The three card slots 31 have the same center, the width of the card slots 31 is the same as the width of the positioning substrate 2, the length is not less than the length of the positioning substrate 2, and the depth is greater than 3mm. The angle between adjacent card slots 31 is 60°, which means that the length direction of the three card slots 31 is taken as a line, and the three lines intersect at the same point, and the vicinity of this point is evenly divided into 6 parts, each of which is 60°. Use adhesive wax or other removable adhesive to glue the cutting pad 4 to the front of the cutting substrate 3. Install the cutting substrate 3 to the positioning substrate 2 so that the clamping groove 31 on the cutting substrate 3 clamps the positioning substrate 2. Place the material 5 to be cut on the cutting pad 4, and use the upper plate glue to glue the material 5 to be cut to the cutting pad 4. The glue used ensures that the cutting strength is met and the material can be easily removed after cutting. At this time, the positioning substrate 2 is assembled in any one of the slots 31 on the cutting substrate 3, and the multi-wire cutting equipment is used to perform the first multi-wire cutting on the material 5 to be cut; the cutting pad 4 is lifted up and rotated 60 degrees in one direction, so that the positioning substrate 2 is suitable for being assembled in another slot 31 on the cutting substrate 3, and the multi-wire cutting equipment is used to perform the second multi-wire cutting on the material 5 to be cut; the cutting pad 4 is lifted up again and rotated 60 degrees in the same direction, so that the positioning substrate 2 is suitable for being assembled in the last slot 31 on the cutting substrate 3, and the multi-wire cutting equipment is used to perform the third multi-wire cutting on the material 5 to be cut, and the regular hexagonal prisms that need to be processed in batches can be moved.

[0046] It is worth noting that the length of the three slots 31 on the back of the cutting substrate 3 is not less than the length of the positioning substrate 2. The depth of the three slots 31 can be greater than 3 mm. The rotation direction and rotation angle of each positioning substrate 2 are the same.

[0047] Furthermore, a positioning pin hole 21 is processed in the middle of the end of the positioning substrate 2, and the center of the positioning pin hole 21 is the same as the center of the card slot 31; a positioning column 32 is processed in the middle of the card slot 31, and when the positioning substrate 2 is assembled in the card slot 31, the positioning column 32 is assembled in the positioning pin hole 21.

[0048] In this embodiment, the positioning columns 32 of the cutting substrate 3 and the positioning pin holes 21 of the positioning substrate 2 match and correspond to each other, so that the positioning substrate 2 can better match the cutting substrate 3 and improve the assembly effect.

[0049] Specifically, a positioning pin hole 21 is processed near the middle part of the positioning substrate 2. A positioning column 32 is processed in the middle of the card slot 31. The outer dimensions of the positioning column 32 are the same as those of the positioning pin hole 21 on the positioning substrate 2. The height of the positioning column 32 is not greater than the depth of the positioning pin hole 21 on the positioning substrate 2. The positioning pin hole 21 of the positioning substrate 2 and the positioning column 32 at the center of the back of the cutting substrate 3 can be in the shape of a cylinder, a regular triangular prism or a regular hexagonal prism, and the two should match each other. Since this application is for cutting a regular hexagonal prism, the positioning column 32 is preferably a regular triangular prism, and the three cylindrical surfaces of the positioning column 32 are parallel to the width directions of the three card slots 31.

[0050] Preferably, the center of the positioning pin hole 21 is located at the center of the positioning substrate 2 in the width direction, and the length between the positioning pin hole 21 and the end of the positioning substrate 2 is L, L = (n+0.5)d, (d is the roller groove distance of the multi-wire cutting equipment, n is a natural number).

[0051] In this embodiment, the center of the positioning pin hole 21 on the cutting positioning substrate 2 is related to the position of the roller groove of the multi-wire cutting device, and the positioning pin hole 21 must be reprocessed after the roller is replaced.

[0052] Specifically, the equipment for cutting the positioning substrate 22 and the subsequent three-time cutting of the material 57 to be cut is the same multi-wire cutting equipment, and uses the same pair of rollers. The end cutting surface of the positioning substrate 2 is used as the base surface, and a positioning pin hole 21 is processed at a specific position in the middle. The center of the positioning pin hole 21 is located at the center of the width direction of the positioning substrate 2 in the X direction, and the length L in the Y direction from the above-mentioned base surface is L=(n+0.5)d (d is the groove pitch of the roller in multi-wire cutting, and n is a natural number). When the value of n is taken, the center point of the positioning groove is as close as possible to the center of the length direction of the positioning substrate 2.

[0053] Further, refer to Figures 1 to 4 The present invention provides a multi-wire cutting auxiliary device, including a cutting base plate 1, a positioning substrate 2 and a cutting substrate 3. The positioning substrate 2 is suitable for being installed on the cutting base plate 1. One end of the cutting pad 4 is suitable for assembling a material 5 to be cut. The other end of the cutting substrate 3 is also provided with a plurality of card slots 31. The plurality of card slots 31 have the same center and are arranged at a preset angle. The positioning substrate 2 is suitable for being assembled in any card slot 31 and performing multi-wire cutting.

[0054] In this embodiment, the positioning substrate 2 is suitable for matching with a card slot 31 on the cutting substrate 3 having the same center and set at a preset angle. The positioning substrate 2 is rotated around the same direction by a preset angle multiple times, so that the positioning substrate 2 and the card slot 31 are matched in sequence and multi-wire cutting is used multiple times to cut the material 5 to be cut, so that the material 5 to be cut can be prepared into the required prism more quickly.

[0055] Specifically, the present application takes a regular hexagonal prism as an example. There are three slots 31 on the cutting substrate 3, and the preset angle between adjacent slots 31 is 60°. The material 5 to be cut needs to be cut three times by multi-wire cutting. When in use, a positioning substrate 2 of a certain width and length is installed in the middle part of the cutting base plate 1 of the multi-wire cutting equipment, the cutting substrate 3 is installed on the positioning substrate 2 and clamped, and the cutting pad 4 is bonded to the front of the cutting substrate 3; the material 5 to be cut is bonded to the cutting pad 4, and the first multi-wire cutting is performed; after the cutting is completed, the cutting substrate 3 is lifted and rotated 60° clockwise and then installed on the positioning substrate 2, the positioning substrate 2 and the cutting substrate 3 are clamped, and the second multi-wire cutting is performed; after the cutting is completed, the cutting substrate 3 is lifted and rotated 60° clockwise and then installed on the positioning substrate 22, the positioning substrate 2 and the cutting substrate 3 are clamped again, and the third multi-wire cutting is performed. After the cutting is completed, the required regular hexagonal prism element can be obtained by cleaning and unloading.

[0056] It is worth noting that the cutting pad 4 is used to assemble the material 5 to be cut on the end of the cutting substrate 3, and the material 5 to be cut can also be directly installed on the cutting substrate 3. At the same time, the number of the slots 31 is determined according to the cylindrical surface of the prism to be prepared, which is generally half of the number of cylindrical surfaces of the prism. For example, if you want to prepare a regular octagonal prism, the number of slots 31 is half of the prism side, then 4 slots 31 are required. The preset angles between adjacent slots 31 are equal, so when preparing a regular octagonal prism, the preset angle between the slots 31 is 360°÷(number of slots 31×2)=45 degrees.

[0057] Furthermore, the width direction of the positioning substrate 2 is parallel to the cutting surface of the multi-wire cutting device. The positioning substrate 2 is further provided with a positioning pin hole 21 , and the cutting pad 4 is further provided with a positioning column 32 , which is suitable for being assembled in the positioning pin hole 21 .

[0058] In this embodiment, the positioning columns 32 of the cutting substrate 3 and the positioning pin holes 21 of the positioning substrate 2 match and correspond to each other, so that the positioning substrate 2 can better match the cutting substrate 3 and improve the assembly effect.

[0059] Specifically, the positioning pin hole 21 is located at the center of the positioning substrate 2, and the positioning column 32 is located at the center of the slot 31. The positioning column 32 is any one of a triangular prism, a cylinder, and a rectangular column. Preferably, the positioning column 32 is also a prism, and the number of cylindrical surfaces of the positioning column 32 is equal to the number of the slots 31, and the cylindrical surfaces of the positioning column 32 are parallel to the width direction of the slots 31. Preferably, the cylindrical surfaces of the positioning column 32 are parallel to the width direction of the slots 31, so that the positioning substrate 2 and the cutting substrate 3 are more closely fitted and less prone to shaking. That is, if a regular octagonal prism is cut, the positioning column 32 is preferably a regular quadrangular prism, and the four cylindrical surfaces of the positioning column 32 are respectively parallel to the width directions of the four slots 31. If a regular hexagonal prism is cut, the positioning column 32 is preferably a regular triangular prism, and the three cylindrical surfaces of the positioning column 32 are respectively parallel to the width directions of the three slots 31. Other shapes of the positioning column 32 are not described one by one in this application.

[0060] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
