Description

Technical Field

[0001] The present invention relates to the technical field of multi-wire cutting machines, in particular to a wire mesh structure of a multi-wire cutting machine. Background Art

[0002] Chinese patent CN217395341U discloses a four-guide wheel jacking type multi-wire cutting machine for large stone slabs, including four main guide wheels, which are positioned to form a rectangular structure. The diamond wire is wound in the wire groove of the main guide wheel, thus forming a multi-wire cutting structure. The diamond wire between the two lower main guide wheels is used for cutting, so the distance between the upper and lower main guide wheels directly affects the height of the cut material; if the height of the cut material is greater than the distance between the upper and lower main guide wheels, the upper cutting wire will perform a secondary cut on the material, and the upper cutting wire will have difficulty falling into the cutting groove accurately, which will cause cut marks on the top of the material, resulting in the material being scrapped. In addition, when the lower diamond wire is finished cutting, it will carry dust. When it moves between the upper main guide wheels, the dust will fall onto the lower diamond wire, which will increase the resistance of the lower diamond wire during cutting, causing the diamond wire to break easily and having a short service life.

[0003] Therefore, how to eliminate the impact of the multi-wire saw on the material height and extend the service life of the diamond wire has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In order to solve the technical problems in the background technology, the present invention discloses a wire mesh structure of a multi-wire cutting machine.

[0005] The present invention provides a wire mesh structure of a multi-wire cutting machine, comprising:

[0006] The first guide wheel and the second guide wheel are arranged horizontally and spaced apart;

[0007] The third guide wheel and the fourth guide wheel are arranged horizontally and spaced apart and are lower than the first guide wheel;

[0008] The distance between the third guide wheel and the fourth guide wheel is less than or equal to the distance between the first guide wheel and the second guide wheel, so that the first guide wheel, the second guide wheel, the third guide wheel and the fourth guide wheel form a rectangle or a trapezoid;

[0009] When routing the cutting wire, it is always clamped to the lower ends of the third and fourth guide wheels;

[0010] The cutting line between the third guide wheel and the fourth guide wheel is used for cutting the material.

[0011] The beneficial effects of the present invention are: 1. When the cutting wire is laid out, only a flat wire network is formed in the vertical direction, so the height of the material will not affect the wiring of the cutting wire, and the top of the material will not form a cut due to secondary cutting; 2. The dust carried by the cutting wire after cutting will not fall on the cutting wire being cut, thereby not causing resistance to the cutting wire during cutting, and extending the service life of the cutting wire; 3. The first guide wheel and the second guide wheel are located on both sides of the material and will not hinder the cutting of the material.

[0012] The specific wiring structure of the cutting line is: the cutting line passes around the upper end of the first guide wheel, the lower end of the third guide wheel, the lower end of the fourth guide wheel, the upper end of the second guide wheel, the lower end of the fourth guide wheel, the lower end of the third guide wheel, and the lower end of the first guide wheel in sequence, and then reaches the upper end of the first guide wheel again, and is clamped in different slots along the axial direction of the guide wheel in sequence.

[0013] The number of wire grooves on the guide pulleys is typically equal, which increases processing costs. Therefore, further improvements are: the first and second guide pulleys have the same number of wire grooves and the same spacing; the third and fourth guide pulleys have the same number of wire grooves and the same spacing; and the third guide pulley has twice as many wire grooves as the first guide pulley. Specifically, every two adjacent wire grooves on the third or fourth guide pulley correspond to one wire groove on the first or second guide pulley. The spacing between the wire grooves on the first guide pulley is twice the spacing on the third guide pulley.

[0014] Since the number of wire grooves on the upper guide wheel and the lower guide wheel is different, the cutting line between the first guide wheel and the third guide wheel and the cutting line between the second guide wheel and the fourth guide wheel will be arranged at an angle. If the wire grooves between the first guide wheel and the third guide wheel are offset too much and the wire grooves between the second guide wheel and the fourth guide wheel are offset too much, the cutting line will easily deviate from the wire grooves. Based on this, further improvements are made: one of the wire grooves on the first guide wheel is set as an outer wire groove; the wire groove on the third guide wheel corresponding to the outer wire groove is set as a first inner wire groove and a second inner wire groove; the first inner wire groove and the second inner wire groove are arranged symmetrically relative to the outer wire groove.

[0015] Since pay-out and take-up wheels need to be installed at both ends of the cutting line, and both the pay-out and take-up wheels are driven to rotate by motors; therefore, the position setting of the pay-out and take-up wheels directly affects the complexity of the wire wiring structure. Based on this, further improvements are made in that the input and output ends of the cutting line are located on the same side. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] Example 1:

[0024] like Figure 1 and Figure 2 As shown, the present invention discloses a wire mesh structure for a multi-wire sawing machine, including four guide wheels forming the cutting wire mesh, specifically: a first guide wheel 1 and a second guide wheel 2, arranged horizontally and spaced apart; and a third guide wheel 3 and a fourth guide wheel 4, arranged horizontally and spaced apart and lower than the first guide wheel 1. The first guide wheel 1 and the third guide wheel 3 are adjacent to each other, while the second guide wheel 2 and the fourth guide wheel 4 are adjacent to each other. The spacing between the third guide wheel 3 and the fourth guide wheel 4 is smaller than the spacing between the first guide wheel 1 and the second guide wheel 2, so that the first guide wheel 1, the second guide wheel 2, the third guide wheel 3, and the fourth guide wheel 4 form an isosceles trapezoid.

[0025] The cutting line 5 passes through the upper end of the first guide wheel 1, the lower end of the third guide wheel 3, the lower end of the fourth guide wheel 4, the upper end of the second guide wheel 2, the lower end of the fourth guide wheel 4, the lower end of the third guide wheel 3, and the lower end of the first guide wheel 1, before returning to the upper end of the first guide wheel 1, completing a loop. This loop is repeated, and the cutting line 5 is sequentially engaged in different slots along the axial direction of the guide wheels, forming a cutting network. With this arrangement, the cutting line 5 is always engaged with the lower ends of the third and fourth guide wheels 3 and 4 during routing. The cutting line 5 between the third and fourth guide wheels 3 and 4 is used to cut the material.

[0026] The inlet and outlet ends of the cutting wire 5 forming the cutting wire net are located on the same side. In this way, the motors driving the pay-off and take-up wheels can be installed on the same side of the multi-wire cutting machine, which simplifies the wiring structure of the wires connected to the motors and reduces costs.

[0027] The beneficial effects of the present invention are: 1. When the cutting line 5 is laid out, only a flat wire network is formed in the vertical direction. Therefore, the height of the material will not affect the laying out of the cutting line 5, and the top of the material will not form a cut due to secondary cutting; 2. The dust carried by the cutting line 5 after cutting will not fall on the cutting line 5 being cut, thereby not causing resistance to the cutting line 5 during cutting, and extending the service life of the cutting line 5; 3. The first guide wheel 1 and the second guide wheel 2 are located on both sides of the material and will not hinder the cutting of the material.

[0028] Example 2:

[0029] Compared with the first embodiment, the difference is that the first guide wheel 1 and the second guide wheel 2 have the same number of wire grooves, the corresponding wire grooves are in the same radial position, and the spacing is the same, and the number of wire grooves is set to n (n is a positive integer). The third guide wheel 3 and the fourth guide wheel 4 have the same number of wire grooves, the corresponding wire grooves are in the same radial position, and the spacing is the same. The number of wire grooves of the third guide wheel 3 is twice the number of wire grooves of the first guide wheel 1, and the number of wire grooves is set to 2n. The specific configuration is: every two adjacent wire grooves of the third guide wheel 3 or the fourth guide wheel 4 correspond to one wire groove of the first guide wheel 1 or the second guide wheel 2. The wire groove spacing on the third guide wheel 3 (fourth guide wheel 4) is twice the wire groove spacing on the first guide wheel 1 (second guide wheel 2).

[0030] With this arrangement, the number of wire grooves on the first guide wheel 1 and the second guide wheel 2 is reduced by half, which can reduce the processing cost.

[0031] When winding, one winding cycle of the cutting wire 5 is: the nth wire groove of the first guide wheel 1, the 2n-1th wire groove of the third guide wheel 3, the 2n-1th wire groove of the fourth guide wheel 4, the nth wire groove of the second guide wheel 2, the 2nth wire groove of the fourth guide wheel 4, the 2nth wire groove of the third guide wheel 3, and the n+1th wire groove of the first guide wheel 1.

[0032] like Figure 3 and Figure 4 As shown, one of the wire grooves on the first guide wheel 1 (second guide wheel 2) is set as the outer wire groove 11; the wire grooves on the third guide wheel 3 (fourth guide wheel 4) corresponding to the outer wire groove 11 are set as the first inner wire groove 31 and the second inner wire groove 32. The first inner wire groove 31 and the second inner wire groove 32 are arranged symmetrically with respect to the outer wire groove 11. This can reduce the offset between the outer wire groove 11 and the first inner wire groove 31 and the second inner wire groove 32, preventing the cutting wire 5 from falling out of the wire groove.

[0033] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
