Abstract
The present invention relates to a method for repairing and grinding knives of chemical fiber cutting machines. The method is characterized in that a bloomed type repairing and grinding method for knives of chemical fiber cutting machines is provided; a sorted set repairing and grinding method overcomes the defects of the traditional repairing and grinding method that cutting knives need commensurate cutting feeds and double-face repair and grind no matter how different the use situations are. The present invention has the advantages that a minimum repairing and grinding amount is used for keeping the optimum state of knife edges, a knife can be arranged on a machine for use when a single edge is repaired and ground, the service life of a cutting knife is greatly prolonged, and simultaneously, cut fibers are always kept first-class. Therefore, the present invention benefits the sufficient utilization of resources and saves the production cost.
Description
Technical field
The present invention relates to the Chemical Fibre Project in the caused by spinning industrial production, particularly staple fibre machine cutting off tool.
Background technology
In chemical fibre industry, cutoff tool on the chemical fibre Lummus cutting machine that uses on the short fiber production line, for the length (38 ± 2.3mm) that guarantees staple fibre, the carving the angle and must in using width range (0.05mm), carry out double-side grinding of cutoff tool blade, because of stock removal big, make its life-span have only 5～7 reconditionings will force to scrap, but its price is very expensive, has influenced the cost of short fiber.
Summary of the invention
Technical program of the present invention lies in providing a kind of grinding method in service life of cutoff tool on the chemical fibre Lummus cutting machine that prolongs, on the basis that does not increase equipment, pass through technical combinations, can just can use on the machine after the single face reconditioning, reach the service life that prolongs cutoff tool, reduced the cost of producing short fiber.
The invention provides the grinding method of a kind of chemical fibre silk cutting machine, it is characterized in that comprising the following steps: with cutter
1) cutter is pressed wearing and tearing degree sort merge;
2) clamping method is adorned similar cutter holder routinely;
3) detect the gap of determining abrasive grinding wheel and blade face;
4) start bistrique, determine stock removal, manually feed;
5) unload cutter, it is stand-by to press stock removal classification dress box.
Chemical fibre silk cutting machine described in the above-mentioned steps is with the grinding method of cutter, and the working width, blade situation, the classification of angle, front and back that it is characterized by described sort merge and be by cutter are placed.
Chemical fibre silk cutting machine described in the above-mentioned steps grinding method of cutter, the stock removal that it is characterized by described feed is 0.003mm～0.01mm.
Chemical fibre silk cutting machine provided by the invention is an ambiguity type reconditioning method with the grinding method of cutter, no matter how different overcome the cutoff tool operating position, must be with traditional reconditioning method of amount feed, two-sided reconditioning, advantage is the optimum Working that keeps blade with minimum reconditioning quality, and after the single face reconditioning, just can use on the machine, the reconditioning number of times is expanded to 100 times from 5～7 times, prolonged the life-span of cutoff tool greatly, the grade of cut staple remains on Grade A always simultaneously.This helps resource and makes full use of, and has saved production cost.
Specific embodiment
Chemical fibre disc type cutoff tool grinding method provided by the invention, implementation step is as follows:
1. before the grinding cutter is marked front-back, place respectively;
2. detect with 50 times of projecting apparatus again, active length, cutter that the blade situation is identical are combined into similar cutter group;
3. clamping method clamps similar cutter group routinely;
4. detect the gap of abrasive grinding wheel and blade face behind the dress cutter with the 0.5mm clearance gauge, reach basic gap;
5. with the moving bistrique of setting stick, detect the gap of each abrasive grinding wheel and blade face again with the 0.5mm clearance gauge, adjust the gap of each abrasive grinding wheel and blade face, satisfy mean gap;
6. startup bistrique, the stock removal of determining feed is 0.005mm, manually feed, grinding is finished in the secondary feed;
7. detect with 50 times of projecting apparatus after unloading cutter, the dress box is stand-by.
Ambiguity type reconditioning method provided by the invention, having overcome cutting machine uses cutter because of the operating position difference, must be with traditional reconditioning method of the two-sided reconditioning of amount feed, advantage is the optimum Working that keeps blade with minimum reconditioning quality, and after the single face reconditioning, just can use on the machine, the reconditioning number of times is expanded to 100 times from 5～7 times, prolonged the life-span of cutoff tool greatly, the grade of cut staple remains on Grade A always simultaneously.This helps resource and makes full use of, and has saved production cost.
Claims (3)
1. the grinding method of a chemical fibre silk cutting machine usefulness cutter is characterized in that comprising the following steps:
