Abstract
The utility model discloses a flying shearing machine, wherein a flying shearing machine is arranged behind a roughing mill, the flying shearing machine comprises a speed reduction mechanism, a shearing mechanism and a transmission motor, wherein the speed reduction mechanism and the shearing mechanism are combined into a whole. The flying shearing machine has the beneficial effects that since the speed reduction mechanism and the shearing mechanism are combined into a whole, the structure is simple and compact, and the amount and weight of mechanism components participating in the shearing movement are reduced, thereby lowering the inertia value of movement of the shearing mechanism, reducing the speed changing amount, improving the sensitivity stability and the positioning precision of the shearing mechanism of the flying shearing machine, and improving the shearing quality of the flying shearing machine. Furthermore, the shearing mechanism is a crank connecting rod type mechanism, the shearing torque of the flying shearing machine is great, and the shearing cross section is excellent.
Description
Technical field
The utility model relates to a kind of bar steel rolling production line flying shear, particularly relates to a kind of flying shearing machine of rolled piece on the continuous rolling production line being implemented the timely processing of crop, back-end crop and accident.
Background technology
Flying shearing machine are a kind of equipment of rolled piece being implemented to shear technology in workpiece motion s, are indispensable on the continous way steel rolling production-line, very crucial equipment.Particularly, along with the output and the kind of modernized steel production constantly increases, require steel rolling production to today that high speed, the serialization mode of production develop, the demand of flying shearing machine constantly increases, and naturally and understandably the design and the workmanship of flying shearing machine is had higher requirement.Owing to be at the volley rolled piece implement to be sheared, 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, all must have very high requirement, existing flying shearing machine are difficult to satisfy above-mentioned requirements.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and be quick on the draw, move accurately, the stable and reliable operation flying shearing machine.
The technical scheme that the utility model adopted is: a kind of flying shearing machine, and described flying shearing machine are arranged on after the roughing mill, before the middle milling train; Described flying shearing machine comprise reducing gear, cutting mechanism and driving motor, and described reducing gear and cutting mechanism are combined as a whole.
Described reducing gear is three gear reductions, comprising: high speed shaft, following output shaft and last output shaft; Gears engaged on described high speed shaft and the following output shaft, the gears engaged on described output shaft down and the last output shaft; Described cutting mechanism comprises, connecting rod, knife rest and haircut; Described output shaft and the following output shaft gone up is connected with pin joint on the knife rest respectively, and an end of described connecting rod and the casing of reducing gear are connected, and the other end of described connecting rod is connected with another pin joint on the knife rest.
Described high speed shaft is a gear shaft, and described output shaft down and last output shaft are bent axle.
The beneficial effects of the utility model are: because reducing gear and cutting mechanism are an integral body, simple and compact for structure, the mechanism's number of components and parts and the weight that participate in shearing motion have been reduced, to reduce the inertia value of cutting mechanism motion, the variable quantity of minimizing speed, improve the sensitive stability and the positioning accuracy of flying shearing machine cutting mechanism, thereby improve the shearing quality of flying shearing machine.Cutting mechanism is a crank-linkage type mechanism in addition, and the flying shear shearing moment is big, and the shearing section is good.

The specific embodiment
Below in conjunction with the drawings and specific embodiments flying shearing machine are described in further detail:
As depicted in figs. 1 and 2, the utility model flying shearing machine are arranged on after the roughing mill, and before the middle milling train, this setting can make rolled piece carry out cutting head cutting tail before the milling train in entering, once middle milling train can be cataclasm with rolled piece when accident occurring, prevent to fly the generation of steel accident; Described flying shearing machine comprise reducing gear, cutting mechanism 5 and driving motor 1, described reducing gear and cutting mechanism are combined as a whole, compact conformation can reduce mechanism's number of components and parts and the weight that participates in shearing motion, to reduce the inertia value of cutting mechanism motion, the variable quantity of minimizing speed, improve the sensitive stability and the positioning accuracy of flying shearing machine cutting mechanism, thereby improve the shearing quality of flying shearing machine.Described reducing gear is three gear reductions, comprising: high speed shaft 2, following output shaft 3 and last output shaft 4, and described high speed shaft 2 is a gear shaft, described upper and lower output shaft is bent axle; Described cutting mechanism comprises connecting rod 51, knife rest 52 and haircut; Described upper and lower output shaft is connected with pin joint on the knife rest 52 respectively, and the two ends of described connecting rod 51 are connected with another pin joint on the knife rest 52 with the casing of reducing gear respectively; The output shaft of driving motor 1 and high speed shaft 2 are connected transferring power by crown gear coupling, and the gears engaged on described high speed shaft 2 and the following output shaft 3 can realize slowing down, and drives the linkage running by upper and lower output shaft rotation and realizes the shearing workpiece.
It is 60 * 60～100 * 100 or the rolled piece of φ 70～φ 110 that these flying shearing machine are particularly suitable for the shearing section, and its cutting mechanism eccentric shaft eccentric throw is: 140～180mm.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode, and according to basic fundamental design of the present utility model, those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection domain of the present utility model.
