Thread-rolling machine capable of preventing sweeps from leaving on thread-rolling plates

Abstract

The invention discloses a thread-rolling machine capable of preventing sweeps from leaving on thread-rolling plates. The thread-rolling machine comprises a rack, the rack is provided with the fixed thread-rolling plate and the movable thread-rolling plate, the two ends of the fixed thread-rolling plate are an inlet and an outlet for screws correspondingly, a first sweep removing spraying pipe is arranged at the position, corresponding to the inlet, of the rack, a second sweep removing spraying pipe is arranged at the end, corresponding to the outlet, of the movable thread-rolling plate, the axes of the first sweep removing spraying pipe and the second sweep removing spraying pipe are the same as the axes of the screws, the first sweep removing spraying pipe and the second sweep removing spraying pipe are provided with spraying openings, the spraying opening of the first sweep removing spraying pipe faces the movable thread-rolling plate, and the spraying opening of the second sweep removing spraying pipe faces the fixed thread-rolling plate. The thread-rolling machine can remove the sweeps on the thread-rolling plates, cannot affect the screws, ensures the thread rolling quality ofthe screws, and has the cooling effect.

Description

technical field [0001] The invention belongs to the field of thread rolling machines, and more specifically relates to a thread rolling machine for preventing waste left by a thread rolling plate. Background technique [0002] Thread rolling machine is an equipment specialized in the production of screws. The patent No. CN201520589255.6 is an automatic cycle thread rolling machine that can complete automatic feeding. During the feeding process, it avoids the problems of complicated operation and safety for workers, and the effect of thread rolling is good. However, currently in the process of bolt processing, Excess waste will be produced on the thread rolling board, which will affect the processing effect of the bolts to a certain extent and reduce the quality of the bolts; at the same time, in the thread rolling process, in order to reduce the local high temperature and prolong the life of the thread rolling board, it is necessary to spray The coolant cools down the workp...

The patent No. CN201520589255.6 is an automatic cycle thread rolling machine that can complete automatic feeding. During the feeding process, it avoids the problems of complicated operation and safety for workers, and the effect of thread rolling is good. However, currently in the process of bolt processing, Excess waste will be produced on the thread rolling board, which will affect the processing effect of the bolts to a certain extent and reduce the quality of the bolts; at the same time, in the thread rolling process, in order to reduce the local high temperature and prolong the life of the thread rolling board, it is necessary to spray The coolant cools down the workpiece and thread rolling board

[0003] However, although the spraying coolant cools down the thread rolling board, the cooling liquid is sprayed downward from the upper part, that is, it is perpendicular to the extending direction of the tooth lines on the thread rolling board, so it cannot wash away the waste chips, and some waste chips still remain on the thread rolling board. On the thread board, it will affect the screw that is re-rolled, so that the thread on the surface of the screw is not smooth enough or even misplaced
