Description

Technical Field

[0001] The utility model belongs to the technical field of stone cutting, in particular to a novel four-column four-roller downward pressure multi-wire cutting equipment. Background Art

[0002] At present, with the development of diamond wire cutting machine tools, diamond wire multi-wire cutting machine tools have gradually been used in the stone processing industry. In stone processing, oversized stone processing has always been a difficult point in the cutting industry. Diamond wire stone cutting machines use diamond wires to process natural stone or other large-size materials. The size and weight of stone blocks are much larger. A block generally exceeds 20 tons, and the length, width and height generally exceed 3000×2000×2000mm. In recent years, stone multi-wire cutting systems and devices have been proposed one after another, including a hollow multi-wire cutting machine frame and a downward pressure multi-wire cutting device (application number CN202320134594.X), a large multi-wire cutting machine frame and a downward pressure multi-wire cutting device (application number CN202310067687.X) and other patents. The structure adopts a two-column support frame. Although both have corresponding stability, they cannot meet the stability requirements of large multi-wire cutting equipment. Moreover, when the overall structure needs to be proportionally larger, the casting processing difficulty will be higher, the overall cost will be higher, and the structure will be more bulky. Summary of the invention

[0003] The utility model aims to propose a novel four-column four-roller downward pressure multi-wire cutting equipment, the key components of which are all high-strength casting structures with good shock absorption and stable structure.

[0004] The technical solution adopted by the utility model is: a novel four-column four-roller downward pressure multi-wire cutting equipment, including a four-column multi-wire mechanism and an upper and lower feeding frame body;

[0005] The four-column multi-line mechanism comprises a left column assembly, a right column assembly, a connecting crossbeam and a connecting longitudinal beam, wherein the connecting crossbeam is fixed to the outside of the left column assembly and the right column assembly by bolts, and the connecting longitudinal beam is fixed between two supporting columns of the left and right column assemblies by bolts;

[0006] The left column assembly and the right column assembly each include two supporting columns and a base; the two supporting columns are installed above the base;

[0007] The support column includes a column, a linear guide rail module and a screw rod module; the screw rod module is installed on the inner side of the column, and the linear guide rail module is installed on both sides of the column;

[0008] The upper and lower feeding frame bodies include a left main frame, a right main frame, a feeding beam, a cutting main roller, a main shaft box, a slave shaft box, a wire-retracting and releasing mechanism, a wire-arranging mechanism, a tensioning mechanism and a wire-guide wheel mechanism;

[0009] The upper and lower feed frame bodies are fixedly connected together by the left main frame and the right main frame through the feed crossbeam; the left main frame and the right main frame are respectively connected to the corresponding support columns for sliding up and down, and the left main frame and the right main frame structure are designed with support seats for installing the main shaft box and supporting the two axial ends of the slave shaft box, and both ends of the four cutting main rollers are assembled with the main shaft box and the two axial ends of the slave shaft box; the retractable wire mechanism, the wire arrangement mechanism, the tensioning mechanism and the guide wheel mechanism constitute the retractable wire system in sequence, which are symmetrically installed on the back of the left main frame and the right main frame respectively; the diamond wire starts from the retractable wire system on one side, and after winding around the four cutting main rollers according to the set route, it is connected to the retractable wire system at the other end to complete the overall wiring; the diamond wire arranged between the two cutting main rollers under the frame is formed for cutting the mesh surface.

[0010] Furthermore, the column and the base are an integrally cast structure, and reinforcing ribs are provided in the structure to connect them to each other.

[0011] Furthermore, the left main frame and the right main frame are both grid structures.

[0012] The beneficial effects of the utility model are as follows: the four supporting columns in the utility model are supported by the base in pairs, so that the structural layout is more reasonable and the overall mechanical structure is more stable; the upper and lower feeding mechanisms are directly controlled by the servo system, and the feeding control is more precise; the upper and lower feeding mechanisms are gate-type mechanisms, which can realize that after the entire stone cutting is completed, the subsequent rough material vehicle continues to feed and cut the next stone, and the combination of the retractable wire mechanism and the upper and lower feeding mechanisms reduces the number of wire wheels, shortens the diamond wire routing distance, and reduces the wire breakage rate; the cutting main roller assembly is a four-roller matrix arrangement, which is synchronously controlled by the servo system, and can realize multi-wire stable cutting; the overall structure of the utility model is more reasonable, which improves the stability of the machine tool system, reduces the production process flow, improves the processing efficiency, reduces the wire breakage rate, and fully meets the market demand for one-time stable processing of oversized stone.

[0024] like Figure 1 As shown, the utility model is a novel four-column four-roller downward pressure multi-wire cutting equipment, comprising a four-column multi-wire mechanism 1 and an upper and lower feeding frame body 2.

[0025] like Figure 2 As shown, the four-column multi-line mechanism 1 includes a left column assembly 101, a right column assembly 102, a connecting crossbeam 103 and a connecting longitudinal beam 104. The connecting crossbeam 103 is fixed to the outside of the left column assembly 101 and the right column assembly 102 by bolts, and the connecting longitudinal beam 104 is fixed between the two supporting columns of the left and right column assemblies by bolts, forming a structure for the up and down feeding frame body movement.

[0026] like Figure 3 and Figure 4As shown, the left column assembly 101 and the right column assembly 102 each include two supporting columns 101a and a base 101b; both supporting columns 101a are installed above the base 101b; the supporting column 101a includes a column 101aa, a linear guide module 101ab and a screw module 101ac; the screw module 101ac is installed on the inner side of the column 101aa, and the linear guide module 101ab is installed on both sides of the column 101aa. The column 101aa and the base 101b are an integral casting structure, and there are reinforcing ribs connected to each other in the structure, so that the force on the column is not concentrated in one place, which can greatly increase the stability of the overall structure. The two connecting surfaces of the column and the base are scraped and ground, and connected together by bolts; the designed casting base allows the entire four-column multi-line mechanism to be accurately adjusted through the machine tool special pad during installation and debugging, ensuring the installation accuracy of the machine tool equipment.

[0027] like Figure 5 and Figure 6 As shown, the upper and lower feeding frame body 2 includes a left main frame 201, a right main frame 202, a feeding crossbeam 203, a cutting main roller 204, a main shaft box 205, a slave shaft box 206, a wire-retracting mechanism 207, a wire-arranging mechanism 208, a tensioning mechanism 209 and a wire pulley mechanism 210; the upper and lower feeding frame body 2 is fixedly connected by the left main frame 201 and the right main frame 202 through the feeding crossbeam 203, wherein the left main frame 201 and the right main frame 202 are both grid structures. The left main frame 201 and the right main frame 202 are respectively connected to the corresponding supporting columns 101a in an up-and-down sliding manner, and the left main frame 201 and the right main frame 202 are designed with support seats for mounting the main shaft box 205 and the slave shaft box 206 at both ends of the axial direction, and both ends of the four cutting main rollers 204 are assembled with the main shaft box 205 and the slave shaft box 206 at both ends of the axial direction.

[0028] like Figure 7 As shown, the wire-retracting and -releasing mechanism 207, the wire-arranging mechanism 208, the tensioning mechanism 209 and the wire-reel mechanism 210 sequentially constitute a wire-retracting and -releasing system, which are symmetrically mounted on the back of the left main frame 201 and the right main frame 202, respectively.

[0029] like Figure 8 As shown, the diamond wire starts from the pay-off and take-up wire system on one side, passes through four cutting main rollers according to the set route, and is connected to the pay-off and take-up wire system at the other end to complete the overall wiring; the diamond wire arranged between the two cutting main rollers under the frame is used to cut the mesh surface.

[0030] like Fig. 9As shown, when the rough material truck carrying the stone arrives at the designated position of the cutting equipment, the whole system starts to operate, the up and down feeding cutting body is guided by the linear module, the screw module drives the lifting, and the cutting main roller drives the diamond wire to rotate synchronously to achieve the purpose of stone cutting.
