Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting machines, and in particular to a multi-wire cutting unit and a multi-wire cutting machine with stable tension. Background Art

[0002] Stone is widely used in construction. To turn a block of stone into slabs, it requires cutting tools. Wire EDM (Wire Cutting Machine) is popular for its advantages, such as small kerfs. With the continuous advancement of technology, wire EDM has been widely used in stone cutting.

[0003] The wire cutting machine is mainly composed of a bracket and a cutting unit, wherein the cutting unit is provided with 4 rollers, and the 4 rollers are wound with cutting wires, and the cutting wires will form a cutting mesh between the 2 rollers below; for example, the Chinese invention patent with application number CN202210406677.X discloses a four-column four-guide wheel jacking type multi-wire cutting machine for large stone slabs. However, existing wire cutting machines have the following defects in actual use: 1. The entire wire cutting machine is equipped with only one set of wire-reeling and rewinding devices (i.e., two wire-reeling and rewinding devices) and one cutting wire. Therefore, on the one hand, the cutting wire can only rely on the mutual pulling force of the two wire-reeling and rewinding devices to achieve the tension of the cutting wire. Moreover, the cutting wire needs to be wound around four rollers multiple times to form the entire cutting mesh. Due to the influence of the cutting wire's own weight and the friction on the rollers, it is difficult to maintain the tension of each cutting wire segment on the cutting mesh, which affects the actual cutting effect. On the other hand, the cutting wire is easily consumed, and the cutting wire needs to be frequently replaced. The cutting wire replacement process is very complicated, which affects actual production. 2. The rollers are relatively inconvenient to disassemble and assemble. 3. During use, the span of the cutting mesh cannot be adjusted according to actual needs. If the span of the cutting mesh is too large or too small, it will have adverse effects. In view of the above-mentioned problems, the inventors of this case conducted in-depth research on this issue, which led to the creation of this case. Summary of the Invention

[0004] In view of the above-mentioned technical problems of the present invention, the purpose of the present invention is to provide a multi-wire cutting unit and a multi-wire cutting machine with stable tensioning force, which is conducive to maintaining the tensioning force of each cutting line segment on the multi-wire cutting unit stable and reducing the frequency of replacing the cutting line; at the same time, it can also facilitate the disassembly and assembly of the roller roller and realize the adjustment of the span of the cutting mesh surface.

[0009] Furthermore, the first bearing body and the second bearing body both include support columns located on both sides and a plurality of support beams connected between the two support columns. The first bearing seat and the support columns are integrally formed, and the notch of the roller bracket is arranged obliquely upward or vertically upward.

[0010] Furthermore, the first carrying body and the second carrying body are both provided with at least one supporting plate on a side facing away from the roller;

[0011] The first pay-off and take-up device and the second pay-off and take-up device each comprise a pay-off and take-up mechanism slidably arranged on a support plate, a first sliding drive mechanism being arranged between the pay-off and take-up mechanism and the support plate, and the pay-off and take-up mechanism being driven by the first sliding drive mechanism to slide and adjust along the axis direction of the roller;

[0012] The first pay-off and the second pay-off and take-up device also include a tensioning mechanism slidably arranged on the supporting beam, a second sliding drive mechanism is arranged between the tensioning mechanism and the supporting beam, and the tensioning mechanism is driven by the second sliding drive mechanism to slide and adjust along the axial direction of the roller; the pay-off and the take-up mechanism and the tensioning mechanism are arranged at different heights.

[0013] Furthermore, it also includes a load-bearing frame adjustment mechanism. The load-bearing frame adjustment mechanism is provided on both sides of the first load-bearing body, and the load-bearing frame adjustment mechanism drives the first load-bearing body to move and adjust in a direction away from or close to the second load-bearing body.

[0014] Furthermore, the carrier frame adjustment mechanism includes a guide post, a guide post support and a telescopic cylinder;

[0019] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0020] 1. On the one hand, compared with the existing method of setting up one set of take-up and pay-out devices and one cutting line, by adopting multiple sets of take-up and pay-out devices and multiple cutting lines, each cutting line can be wound around only a part of the four rollers, which can not only reduce the weight of each cutting line itself, but also reduce the friction between the rollers, making the tension of each cutting line more stable, and thus keeping the tension of each cutting line segment on the cutting mesh formed by the entire multi-line cutting unit stable, which helps to improve the cutting effect; on the other hand, compared with the existing method of using one cutting line, the use of multiple cutting lines can effectively reduce the frequency of cutting line replacement, thereby reducing the impact on actual production.

[0021] 2. By designing that the first bearing body and the second bearing body face each other, both sides are provided with first bearing seats at the upper and lower ends, and each first bearing seat is detachably connected to a first tightening member; so that in the actual use process, when the roller roller is to be disassembled, it is only necessary to disassemble and separate the first tightening member from the first bearing seat; and when the roller roller is to be installed, it is only necessary to place the roller roller in the roller roller bracket and tighten it with the first tightening member. Therefore, it is very convenient to disassemble and replace the roller roller.

[0022] 3. By arranging support plates on the sides of the first load-bearing body and the second load-bearing body facing away from the roller roller, and designing the first pay-off and take-up device and the second pay-off and take-up device to include a pay-off and take-up mechanism slidably arranged on the support plates and a tensioning mechanism slidably arranged on the supporting beam; during specific use, not only can the positions of the pay-off and take-up mechanism and the tensioning mechanism be flexibly adjusted according to actual use requirements, but also it can be ensured that the pay-off and take-up mechanism and the tensioning mechanism do not affect each other during operation, which can bring great convenience to the actual installation and use of multiple pay-off and take-up devices.

[0023] 4. By arranging the bearing frame adjustment mechanism on both sides of the first bearing body, the bearing frame adjustment mechanism can be used to drive the first bearing body to move away from or close to the second bearing body during actual use, thereby realizing flexible adjustment of the span of the cutting mesh surface to meet the cutting requirements of various specifications of stones and ensure the cutting effect.

Therefore, features defined as "first," "second," and the like may explicitly or implicitly include one or more of such features. Example 1

[0047] See also Figures 1 to 8 As shown, the present invention provides a multi-wire cutting unit 100 with stable tensioning force, and the multi-wire cutting unit 100 includes a carrier frame 1, a first wire-reeling device 2, a second wire-reeling device 3, a cutting wire 4 and four rollers 5 installed on the carrier frame 1; wherein, the carrier frame 1 is used to carry various components such as the first wire-reeling device 2, the second wire-reeling device 3, and the rollers 5; the first wire-reeling device 2 and the second wire-reeling device 3 are both used to realize the wire-reeling and wire-reeling functions; the cutting wire 4 can specifically adopt a diamond cutting wire to realize the cutting function; the rollers 5 are used to wind the cutting wire 4 and drive the cutting wire 4 to transmit and realize cutting.

[0048] At least two first pay-off and take-up devices 2 are provided at one end of the carrier frame 1, and at least two second pay-off and take-up devices 3 are provided at the other end of the carrier frame 1; the four rollers 5 are divided into at least two independent winding partitions in sequence along the length direction, and a cutting line 4 is wound around each independent winding partition of the four rollers 5, one end of each cutting line 4 is connected to a first pay-off and take-up device 2, and the other end of each cutting line 4 is connected to a second pay-off and take-up device 3.

[0049] The present invention divides the four rollers 5 into at least two independent winding partitions along the length direction, and winds a cutting line 4 in each independent winding partition, and connects one end of each cutting line 4 to a first take-up and pay-out device 2, and connects the other end of each cutting line 4 to a second take-up and pay-out device 3; so that in the specific use process, on the one hand, compared with the existing method of setting a set of take-up and pay-out devices and one cutting line, by adopting multiple sets of take-up and pay-out devices and multiple cutting lines 4, each cutting line 4 can be wound around only a part of the four rollers 5, which can reduce the self-gravity of each cutting line 4 and the friction between the rollers 5, so that the tension of each cutting line 4 is more stable, and thus the tension of each cutting line segment on the cutting mesh formed by the entire multi-line cutting unit 100 can be kept stable, which helps to improve the cutting effect; on the other hand, compared with the existing method of using one cutting line, the use of multiple cutting lines can effectively reduce the replacement frequency of the cutting line 4, thereby reducing the impact on actual production.

[0050] In some embodiments of the present invention, the four rollers 5 are sequentially divided into at least two independent winding sections of equal size along the length direction. By making the sizes of the independent winding sections equal, the tension of each cutting line 4 can be made more balanced. In order to better maintain the stability of the tension of each cutting line segment on the cutting surface and effectively reduce the replacement frequency of the cutting line 4; as a specific embodiment of the present invention, please refer to Figure 8As shown, the four rollers 5 are divided into four independent winding partitions of the same size along the length direction. Four first pay-off and take-up devices 2 are provided at one end of the carrier frame 1, and four second pay-off and take-up devices 3 are provided at the other end of the carrier frame 1. In this way, during specific use, four cutting lines 4 can be wound around the four rollers 5, and each cutting line 4 is correspondingly connected to a first pay-off and take-up device 2 and a second pay-off and take-up device 3. Of course, the above is only a specific embodiment of the present invention, but the present invention is not limited thereto. During specific implementation, the number of independent winding partitions, first pay-off and take-up devices 2 and second pay-off and take-up devices 3 can be adjusted according to actual needs, and the size of each independent winding partition can also be made different.

[0051] In some embodiments of the present invention, the supporting frame 1 includes a first supporting body 11 and a second supporting body 12 arranged at a distance from each other, and first supporting seats 13 are provided at the upper and lower ends on both sides of the facing sides of the first supporting body 11 and the second supporting body 12, and each first supporting seat 13 is formed with a roller bracket 131, and the roller bracket 131 is used to support the roller roller 5. Each first supporting seat 13 is detachably connected to a first tightening member 14, and the two ends of the roller roller 5 are supported on the roller bracket 131, and the two ends of the roller roller 5 are tightened to the first supporting seat 13 by the first tightening member 14. Specifically, the first tightening member 14 and the first supporting seat 13 can be locked together by bolts or screws, so that the first tightening member 14 can tighten the roller roller 5 to the first supporting seat 13.

[0052] The present invention is designed to provide first bearing seats 13 at the upper and lower ends on both sides of the facing sides of the first bearing body 11 and the second bearing body 12, and each first bearing seat 13 is detachably connected to a first tightening member 14; so that in the actual use process, when the roller roller 5 is to be removed, it is only necessary to loosen or remove the first tightening member 14 from the first bearing seat 13; and when the roller roller 5 is to be installed, it is only necessary to place the roller roller 5 in the roller roller bracket 131 and tighten it with the first tightening member 14, so that the roller roller 5 can be removed and replaced very conveniently.

[0053] In a specific implementation of the present invention, both ends of the roller roller 5 are equipped with a clamping body 51, and the roller roller 5 is rotatably connected to the clamping body 51. In addition, a first drive motor 52 is connected to the end of either end of the roller roller 5, so as to use the first drive motor 52 to drive the roller roller 5 to rotate. When installing the roller roller 5, it is necessary to place the clamping bodies 51 at both ends of the roller roller 5 into the roller roller bracket 131, and use the first clamping member 14 to clamp the clamping bodies 51 to the first bearing seat 13. In this way, the first bearing seat 13 can be used to meet the support requirements for the roller roller 5, and the lower roller roller 5 can be driven to rotate by the first drive motor 52.

[0054] In some embodiments of the present invention, the first bearing body 11 and the second bearing body 12 both include support columns 151 located on both sides and a plurality of support beams 152 connected between the two support columns 151. The first bearing seat 13 and the support columns 151 are integrally formed to ensure the support strength of the first bearing seat 13, and the notch of the roller roller bracket 131 is set obliquely upward or vertically upward, so that before the roller roller 5 is tightened by the first tightening member 14, the roller roller bracket 131 of the first bearing seat 13 can be used to support it, thereby making installation more convenient.

[0055] In some embodiments of the present invention, the first carrying body 11 and the second carrying body 12 are both provided with at least one supporting plate 16 on a side facing away from the roller 5;

[0056] The first pay-off and take-up device 2 and the second pay-off and take-up device 3 each include a pay-off and take-up mechanism 61 slidably disposed on the support plate 16. A first sliding drive mechanism 63 is disposed between the pay-off and take-up mechanism 61 and the support plate 16. The pay-off and take-up mechanism 61 is driven by the first sliding drive mechanism 63 to slide and adjust along the axis of the roller 5.

[0057] The first pay-off and take-up device 2 and the second pay-off and take-up device 3 also include a tensioning mechanism 62 slidably arranged on the support beam 152, and a second sliding drive mechanism 64 is arranged between the tensioning mechanism 62 and the support beam 152, and the tensioning mechanism 62 is driven by the second sliding drive mechanism 64 to slide and adjust along the axial direction of the roller roller 5; the pay-off and take-up mechanism 61 and the tensioning mechanism 62 are arranged at different heights, so that the pay-off and take-up mechanism 61 and the tensioning mechanism 62 will not affect each other during operation. It should be noted that, in the present invention, the wire-retracting and -paying mechanism 61 and the tensioning mechanism 62 are both components that must be used in existing wire cutting machines, and their specific structures and working principles are well known to those skilled in the art, so the wire-retracting and -paying mechanism 61 and the tensioning mechanism 62 will not be introduced in detail here; at the same time, at least two sets of sliders 651 and slide rails 652 are used to slide and assemble together between the wire-retracting and -paying mechanism 61 and the support plate 16, and between the tensioning mechanism 62 and the support beam 152, to ensure the stability of the wire-retracting and -paying mechanism 61 and the tensioning mechanism 62 during the sliding process.

[0058] The present invention provides a support plate 16 on the side of the first carrying body 11 and the second carrying body 12 facing away from the roller roller 5, and designs the first take-up and pay-out device 2 and the second take-up and pay-out device 3 to include a take-up and pay-out mechanism 61 slidably set on the support plate 16 and a tensioning mechanism 62 slidably set on the supporting beam; during specific use, not only can the positions of the take-up and pay-out mechanism 61 and the tensioning mechanism 62 be flexibly adjusted according to actual use requirements, but also it can be ensured that the take-up and pay-out mechanism 61 and the tensioning mechanism 62 do not affect each other during operation, which can bring great convenience to the actual installation and use of multiple sets of take-up and pay-out devices.

[0059] In the present invention, the first sliding drive mechanism 63 and the second sliding drive mechanism 64 each include a second drive motor 661, a drive gear 662, and a rack 663. The rack 663 is fixedly mounted on the support plate 16 and the support beam 152. The second drive motor 661 is also mounted on the wire-reeling mechanism 61 and the tensioning mechanism 62. The output end of the second drive motor 661 engages with the rack 663 via the drive gear 662. During operation, the second drive motor 661 drives the drive gear 662 to rotate. Since the rack 663 is fixed to the support plate 16 or the support beam 152, the drive gear 662 and the rack 663 can drive the wire-reeling mechanism 61 or the tensioning mechanism 62 to move and adjust.

[0060] In some embodiments of the present invention, the multi-wire cutting unit 100 also includes a carrier adjustment mechanism 7, and a carrier adjustment mechanism 7 is provided on both sides of the first carrier body 11, and the carrier adjustment mechanism 7 drives the first carrier body 11 to move and adjust in a direction away from or close to the second carrier body 12.

[0061] The present invention provides a load-bearing frame adjustment mechanism 7 on both sides of the first load-bearing body 11, so that during actual use, the load-bearing frame adjustment mechanism 7 can be used to drive the first load-bearing body 11 to move and adjust in the direction away from or close to the second load-bearing body 12, thereby realizing flexible adjustment of the span of the cutting mesh surface to meet the cutting requirements of various specifications of stones and ensure the cutting effect.

[0062] In some embodiments of the present invention, the carrier adjustment mechanism 7 includes a guide column 71, a guide column support 72, and a telescopic cylinder 73, wherein the telescopic cylinder 73 can be specifically an oil cylinder or the like;

[0063] The first bearing body 11 is integrally formed with a second bearing seat 17 in the middle of both sides to ensure the supporting strength of the second bearing seat 17. A guide column mounting groove 171 is formed on the second bearing seat 17. The second bearing seat 17 is detachably connected to a second tightening member 18. Specifically, the second tightening member 18 and the second bearing seat 17 can be locked together by bolts or screws, and the guide column 71 is tightened to the second bearing seat 17 by the second tightening member 18; both ends of the guide column 71 are fixedly supported by the guide column support 72; the telescopic cylinder 73 is installed on the second bearing seat 17, and the movable end of the telescopic cylinder 73 is connected to one of the guide column supports 72.

[0064] The present invention provides a second bearing seat 17 in the middle of both sides of the first bearing body 11, and each second bearing seat 17 can be detachably connected to a second tightening member 18, so that during specific use, when the first bearing body 11 needs to be moved and adjusted, the second tightening member 18 can be loosened to allow the first bearing body 11 to be slidably adjusted relative to the guide column 71; and after the position of the first bearing body 11 is adjusted, the second tightening member 18 needs to be used to tighten the guide column 71 to the second bearing seat 17, so that the first bearing body 11 cannot move during use, thereby improving the stability of use.

[0065] In the specific implementation of the present invention, the guide column support 72 includes a support body 721 and a third fastening member 722 detachably connected to the support body 721. Specifically, the third fastening member 722 can be locked and connected to the support body 721 by bolts or screws, and the end of the guide column 71 is fastened to the support body 721 through the third fastening member 722.

[0066] In some embodiments of the present invention, the support frame 1 further includes a reinforcement beam 19. The reinforcement beam 19 connects both sides of the upper ends of the first and second support bodies 11, 12, thereby integrating the first and second support bodies 11, 12 into a single unit, thereby enhancing the strength of the entire support frame 1. Furthermore, the first support body 11 and the reinforcement beam 19 are connected by a sliding assembly, allowing the first support body 11 to slide and adjust relative to the reinforcement beam 19. In a specific implementation of the present invention, the reinforcement beam 19 is provided with an adjustment slot 191 along its length. A pressure plate 192 is provided on the outer side of the reinforcement beam 19. A locking member (not shown) that passes through the adjustment slot 191 secures the pressure plate 192 to the first support body 11. The locking member can be a nut and bolt. To adjust the sliding position of the first support body 11, the locking member only needs to be loosened. After adjusting the position of the first support body 11, the locking member needs to be re-tightened to prevent the first support body 11 from moving during use.
