TECHNICAL FIELD
[0001] The utility model relates to wire cutting machine technical field more particularly to a wire cutting machine pay-off system. BACKGROUND
[0002] The diamond wire cutting equipment uses diamond wire saw as cutting consumables to cut marble, jade, monocrystalline silicon, semiconductor materials and the like. In actual use, the diamond wire is tightly wound on the pay-off spool, which is driven by a servo motor to rotate at high speed and reciprocate, together with the wire arranging system, tension system and traction system to form a cutting wire net to achieve the effect of reciprocating cutting of the cut material.
[0003] The existing technology adopts the moving mode of the wire arranging guide wheel, and the steel wire often moves left and right on the guide wheel. Especially for the stone cutting equipment, a coarse specification diamond wire is usually used, which leads to the fact that the wire arranging spacing on the spool cannot be kept stable, thereby causing instability in the diamond wire pay-off process. Moreover, the existing technology causes the steel wire to bend twice by 90 degrees from the pay-off to the tension system when the wire arranging guide wheel and the spool are in a parallel state, thereby significantly reducing the service life of the steel wire during operation, aggravating the friction of the guide wheel, reducing the service life, and increasing the cost of consumables in the cutting process. In addition, the twisting of the steel wire also changes the straight-line sawing of the steel wire into cutting with a certain twist during the cutting process, which also deteriorates the surface quality of the cut material. Since the uniformity of the wire arrangement is poor in the pay-off process of the existing technology, and there is twisting in the cutting process, the cutting speed of the diamond wire cannot be improved all the time, and the cutting speed of the diamond wire is usually in a square proportion to the cutting efficiency. This greatly reduces the cutting efficiency. The pay-off of the existing technology is usually symmetrically arranged in two planes, which makes the operator have to operate separately in two planes during equipment operation. If a problem occurs in one operating position, it cannot be observed in the other plane, which increases the difficulty of equipment operation and the probability of failure. The pay-off system of the existing technology usually adopts a double-top type, and the left and right tips are arranged separately, which inevitably causes the coaxial problem. The coaxiality of the left and right tips is usually affected by a series of size chains, and the coaxiality of the left and right tips can only be controlled at about 0.1. On the one hand, this makes the diamond wire spool unable to operate coaxially, which reduces the wire arranging accuracy of the diamond wire. On the other hand, it also limits the operating speed of the diamond wire pay-off shaft, thereby affecting the overall wire speed and operating efficiency of the diamond wire equipment. At the same time, it also makes the equipment operate with a large noise and the pay-off shaft has a short service life. SUMMARY
