Description
Technical Field
The invention relates to the field of multi-wire cutting machines, in particular to a main guide wheel capable of reducing deformation.
Background
The diamond wire is a cutting tool manufactured by electroplating diamond on the outer layer of a metal steel wire, the diamond wire is widely applied to the industries of cutting photovoltaic silicon wafers, sapphires, graphite, magnetic materials and the like at present, all processing objects in the field of diamond wire cutting which is popularized are artificial materials, the materials are uniform, the specifications are uniform, the sizes are small, the length and the width of a cutting object are generally smaller than 500mm, 500mm and 300mm, the sectional area of a cut finished product is smaller than 300mm and 300mm, the diameters of the diamond wires which are generally used are 0.03-0.2mm and different, the working tensions of the diamond wires with different wire diameters are 3-30N and different, and the cutting stroke is generally smaller than 400mm. The diameter of the main roller of the existing multi-wire cutting machine of different types is smaller (the diameter is different from 100mm to 200 mm), the length is shorter (the diameter is different from 400mm to 900 mm), the outer diameter of the wire winding wheel is smaller than 250mm, and the diameter of the small wire passing wheel is smaller than 150mm.
The traditional stone cutting is generally carried out by adopting materials with alloy tool bits such as saw blades, rope saws, band saws and the like, the hard alloy has certain thickness, so that unequal saw gaps of 3-10mm can be formed in the process of cutting the stone by the traditional tool, and the hard alloy tool is in rigid contact with the stone in the processing process and vibrates greatly, so that the stone is easy to break in the processing process, and the plate with the thickness of more than 10mm can be generally processed. And diamond wire and stone material flexible contact do not have instantaneous impact load, and the vibrations noise is little low, and the small cutting kerf of line footpath is not more than 1mm moreover, not only can improve the yield greatly, can directly process out the sheet metal that thickness is less than 5mm moreover on the raw materials and can not make the stone material take place the breakage in the cutting process. However, the natural stone has many special features, firstly, the dimension of the stone raw material is not uniform, the general dimension is large and the weight is also large, generally, one raw material exceeds 20 tons, the length, the width and the height can exceed 3000 × 2000mm, and the cross section area of the processed stone large plate can reach 3000mm × 2000mm. And the Mohs hardness of the stone is different from 2 to 9 grades, the hardness difference of different varieties is very large, even if the materials of different positions of the same block of rough material are different, and in addition, the natural stone is provided with cracks and holes, the materials are very complicated, so that the phenomenon of wire breakage is very easy to occur when diamond wire cutting is adopted for cutting the stone. Once the broken wire appears, the diamond wire cutting saw seam is very little, can be because internal stress produces the deformation after the stone material cutting or because of the tension of cooling water leads to the stone material absorption together, thereby can lead to the stone material to carry out the wiring cutting again and make the stone material of cutting half scrap and cause the loss. When the diamond wire is used for cutting stone and a good effect is achieved, the wire breakage rate of the diamond wire in the cutting process needs to be reduced by adopting a larger wire diameter, and the tensioning of the diamond wire needs to be guaranteed by matching with a larger tension force at the same time. Meanwhile, one piece of stone raw material weighs twenty-three tons, a plate with the square of more than 500 is produced by one-time processing, stone has strong abrasiveness, and the consumption of wire per unit area for cutting a knife by adopting diamond wires is far larger than that for cutting other small-sized artificial materials, so that a reel with large wire storage capacity is required to finish processing one large piece of raw material at one time. Meanwhile, the span between the large-size raw material main roller wheels exceeds 2000mm, the heat accumulated by friction and heating in the cutting process is difficult to dissipate, and meanwhile, stone powder is difficult to drain, so that a larger cooling water quantity is needed to cool a diamond wire and wash out cut objects, and the cooling water and the stone powder with pressure formed in high-speed cutting also can meet higher requirements on the waterproof performance of the bearing box.
In the field of processing stone, the length, width and height of the stone crude material are much more than 3000 x 2000 x 2000mm, the cutting sectional area is more than 3000 x 2000mm, and only a cutting net surface can contact with an object to be cut during diamond wire cutting, so that the optimal structure is that a parallel four-roller structure is adopted to form the cutting net surface. Meanwhile, the diameter of the diamond wire suitable for stone machining is more than 0.3mm, the working tension of the diamond wire is more than 60N, and the main roller bears huge radial force, so that the size of the main roller suitable for stone machining industry is far larger than that of rollers in other fields, the length needs to be more than 1000mm, and the diameter is more than 220mm. The large-size main roller has the problems that the driving mechanism for driving the large-size main roller to rotate consumes large power due to large weight and is easy to deform due to large span.

As shown in fig. 4, the guide wheel body 1 has a plurality of wire grooves 15 axially spaced around its outer circumference for winding a diamond wire f.
The main guide wheel that reduces deformation sets up pretension portion in this internal setting of guide pulley, sets up two pretension heads at the both ends of pretension portion, and first part and second part are to locking the back, and axial pretightning force is applyed to pretension portion to two centre gripping heads, when the main guide wheel is receiving radial force to produce bending deformation, just must overcome the axial force of applying earlier, just so can play the effect that reduces main guide wheel bending deformation, and can alleviate guide wheel weight, reduce the manufacturing cost of guide wheel and reduce the power consumption of guide wheel when using.
Further, the axial pretension of the two clamping heads 211,221 is adjustable.
Preferably, as shown in fig. 6 to 7, the locking portion 212 of the first member 21 is formed by an outer rod 212 inserted into a hollow pre-tightening hole, the clamping head 211 of the first member 21 is fixed to an axially outer end of the outer rod 212, an inner threaded hole extending along an axial direction of the outer rod 212 is formed inside the outer rod 212, the locking portion 222 of the second member 22 is formed by an inner rod 222, the clamping head 221 of the second member 22 is fixed to an axially outer end of the inner rod 222, an outer thread is formed on an outer peripheral wall of the inner rod 222 and is connected and fixed to the inner threaded hole of the outer rod 212, and through holes 213,223 inserted into the tie rods a and extending along the axial direction are formed inside the outer rod 212 and the inner rod 222.

As a further improvement, the inner peripheral wall of the accommodating cavity 13,14 is a second circular truncated cone surface 131,141 with the inner diameter gradually decreasing from outside to inside. Because the inner wall of the accommodating cavity 13,14 is in a conical structure, the main shaft of the bearing box, the pull rod a in the middle and the guide wheel body 1 outside the bearing box rotate at a high speed, and cooling water can be thrown out along the inner wall of the accommodating cavity, so that a waterproof effect is achieved.
While the invention has been illustrated and described with respect to specific embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention. It is understood, therefore, that the invention is not to be in any way limited except by the appended claims and their equivalents.
