Method and device for reducing abrasions of grooved wheels and guide wheel in multi-line cutting machine

Abstract

The invention relates to a method for reducing abrasions of grooved wheels and a guide wheel in a multi-line cutting machine. In a cutting process of the multi-line cutting machine, a cutting wire in a wire feeding wheel is delivered into a first groove of a grooved wheel, then uniformly distributed in various grooves of the grooved wheel, and then delivered into a take-up wheel after coming out from a last groove of another groove wheel; and during cutting, grinding slurry is adhered on the surface of the cutting wire at an arrangement part of a product support. The method is characterized in that air curtains are formed at two sides of the product support by high-pressure air flows to close the grinding slurry on a section of cutting wire at the arrangement part of the product support. According to the invention, the grinding slurry is closed in a part needed to be used, thus the grinding slurry in a position for delivering the cutting wire of the guide wheel and the grooved wheels is less, the abrasions to the guide wheel and the grooved wheels of the cutting wire are reduced, and the using cost is reduced.

Description

technical field [0001] The invention relates to a multi-wire cutting machine, in particular to a method and a device for reducing wear of grooved wheels and guide wheels in the multi-wire cutting machine. Background technique [0002] During the cutting process of the multi-wire cutting machine, the cutting wire in the wire feeding wheel is transported into the first groove of the sheave through a series of guide wheels, and then evenly distributed in each groove of the sheave, and then from another groove It comes out of the last groove of the wheel, and then is conveyed into the take-up wheel through a series of guide wheels. When cutting, the abrasive slurry will adhere to the surface of the cutting wire (process requirements), so the guide wheel and groove will be worn when the cutting wire is running. Wheels, these two spare parts consume a lot; at the same time, due to the wear and tear of these two parts, the frequency of cutting line breakage increases greatly, which...

Wheels, these two spare parts consume a lot; at the same time, due to the wear of these two parts, the frequency of cutting line breakage increases greatly, which seriously affects normal production and brings more product scrap
