Abstract

The utility model discloses a flying shear, flying shear sets up after the finishing mill for the finished product rod carries out the multiple length and divides disconnected optimized shear, include: reduction gears, shearing mechanism and drive machine, the input shaft of drive machine's output shaft drive reduction gears passes through crown gear coupling and connects transmission power, reduction gears and shearing mechanism combine as an organic wholely, reduce the quantity and the weight of mechanism's spare part of participation shearing movement. The beneficial effects are that: since the reduction gears with shear the mechanism and be one whole, simple structure is compact, has reduced the quantity and the weight of mechanism's spare part of participation shearing movement to reduce the inertia value of shearing mechanism motion, reduce the change volume of speed, improve sensitive stability and positioning accuracy that flying shear sheared the mechanism, thereby improve flying shear's shearing quality. It is crank connecting rod formula mechanism to shear the mechanism in addition, and it is big that moment is sheared to the flying shear, can shear great specification rolled piece, and the shearing section is good.

Description

A kind of flying shearing machine

Technical field

This utility model relates to a kind of bar steel rolling production line flying shear, particularly relates to a kind of flying shearing machine that rolled piece on continuous rolling production line is implemented crop, back-end crop multiple length segmentation.

Background technology

Flying shearing machine are a kind of equipment that rolled piece is implemented to shear technique in workpiece motion s, are equipment indispensable, very crucial on continuous way steel rolling production-line.Particularly, the yield and the kind that produce along with modernization steel are continuously increased, requiring today that Rolling production develops to high speed, continuous prodution mode, the demand of flying shearing machine is continuously increased, and naturally design and workmanship to flying shearing machine are had higher requirement.Owing to being implement to shear to rolled piece at the volley, therefore, to the kinetic characteristic of flying shearing machine, being quick on the draw property, action accuracy, and each side such as work stability and reliability, it is necessary to having significantly high requirement, existing flying shearing machine are difficult to meet above-mentioned requirements.

Summary of the invention

Technical problem to be solved in the utility model be to provide one be quick on the draw, action accurate, flying shearing machine stable and reliable in work.

This utility model be the technical scheme is that a kind of flying shearing machine, after flying shearing machine are arranged on finishing mill, carries out multiple length disjunction optimizing shear for finished product bar；Including: reducing gear, cutting mechanism and driving motor；The output shaft of described driving motor drives the power shaft of reducing gear to connect transmission power by crown gear coupling；Described reducing gear and cutting mechanism are combined as a whole, and reduce the quantity and weight of the mechanism's parts participating in shearing motion.

Described reducing gear is four gear reductions, including: power shaft, axle of carrier pulley, upper output shaft and lower output shaft；Described power shaft engages with the lower gear of output shaft and the gear of axle of carrier pulley simultaneously, and described axle of carrier pulley engages with the gear of the gear of power shaft and upper output shaft simultaneously.

Described cutting mechanism includes, connecting rod, knife rest and haircut；Described upper output shaft and lower output shaft are connected with the pin joint on knife rest respectively, and one end of described connecting rod is connected with the casing of reducing gear, and the other end of described connecting rod is connected with another pin joint on knife rest.

Described lower output shaft and upper output shaft are bent axle.

The beneficial effects of the utility model are: owing to reducing gear and cutting mechanism are an entirety, simple and compact for structure, decrease the quantity and weight of the mechanism's parts participating in shearing motion, to reduce the inertia value of cutting mechanism motion, reduce the variable quantity of speed, improve sensitive stability and the positioning precision of flying shearing machine cutting mechanism, thus improving the shearing quality of flying shearing machine.Additionally cutting mechanism is crank-linkage type mechanism, and flying shear shearing moment is big, can shear bigger specification rolled piece, and shearing section is good.
