Abstract

The utility model relates to a steel billet blanking machine, which is a metallurgical machinery arranged between a steel billet charging platform and a roller table. The utility model is characterized in that a multistage driving crank shaft arranged on a concrete foundation plane consists of two motors, two reducers, a plurality of couplers, a plurality of driving shafts, a plurality of bearings and a plurality of cranks, the driving shaft is provided with two stopping blocks contacted with a proximity switch on a support to act so as to control the taking and placing processes of steel billet output, furthermore, a journal of each crank is provided with a forkhead-shaped poke rod in sliding manner, the forkhead shape of the poke rod can be used to support a steel billet, a long and thin column-shaped lower section of the poke rod is mounted in sliding manner inside a swing shaft on a support fixed the side of the concrete foundation, thereby, with the rotation of the crank, the poke rod can be driven to repetitively swing left and right and to move up and down, the repetitive motion can make the forkhead shape of the poke rod to support the steel billet to conduct a curve motion, so that the steel billet can be easily place on the roller table from the steel billet charging platform, the collision by the steel billet is avoided to the roller table, and the lifecycle of the equipment is prolonged, and the noise is reduced, and the operation condition is tremendously improved.

Description

The steel billet blanker

Technical field

The utility model is a kind of metallurgical machinery.

Background technology

Now before the rolling mill furnace, steel billet is delivered on the roller-way by the step-by-step movement feeding skid, normally the moving beam by feeding skid moves forward, steel billet is moved near the termination of deciding beam of feeding skid, utilize the oblique downslide of weight of steel billet itself then, drop down onto on the roller-way, but because there are bigger vertical range in feeding skid and roller-way face, and every steel billet substance is heavier, steel billet is pounded on roller-way like this, and roller-way and roller-way side plate are caused very big impact, has a strong impact on service life of equipment, produce very big noise simultaneously, worsened production environment.

Summary of the invention

The purpose of this utility model is a kind of steel billet blanker of design, and steel billet is handled with care to roller-way from the step-by-step movement feeding skid, avoids the bump of steel billet to roller-way face and roller-way side plate, prolongs the service life of roller-way equipment, reduces noise, improves production environment.

The purpose of this utility model is achieved like this: a kind of steel billet blanker, its principal character is by two motors and decelerator and several shaft couplings, power transmission shaft, bearing and crank are formed the more piece driving crank, Motor Drive decelerator outputting power, driving the crank that is positioned on the same horizontal axis by shaft coupling and power transmission shaft again rotates, the jaw shape driving lever that can make rotary oscillation and the compound motion that moves up and down all is installed on each crank, and the common support steel billet of the fork-shaped head of several driving levers is also beaten easily steel billet by certain movement locus and to be put down gently to roller-way from feeding skid.

It is rational in infrastructure that the utility model is carried the steel billet blanker, safe and reliable, operates steadily, and avoided the bump of steel billet and roller-way, prolonged service life of equipment, and noise is little, greatly improved working environment.

Specific implementation method

A kind of steel billet blanker, its principal character is by two motors 1 and decelerator 2 and several shaft couplings 3, power transmission shaft 4, bearing 5 and crank 6 are assembled into the more piece driving crank of same horizontal axis, this more piece driving crank is installed on the plane of the concrete stylobate between steel billet feeding skid and the roller-way as required, between power transmission shaft 4 and the shaft coupling 3 and left side of power transmission shaft 4 and crank 6, right cranked slab 14, all adopt key to link between 15, the left side of crank 6, right cranked slab 14,15 front end rigion boring edge cover is installed the axle journal 16 by fixed head 17 lockings, motor 1 drives decelerator 2 outputting powers like this, again further by shaft coupling 3, power transmission shaft 4 drives crank 6 and rotates, in addition, two link stoppers 8 that keep at a certain distance away are set on the circumference of the power transmission shaft 4 of decelerator 2 outputs, on decelerator 2 bases, draw support 10 to install near switch 9, rotation along with power transmission shaft 4, link stopper 8 with near switch 9 contact actions and produce the intermittently stall of predetermined power transmission shaft, with getting of control steel billet blanking, put action, on the axle journal 16 of each crank 6, all slide in addition and adorn a jaw shape driving lever 7, the head of this driving lever 7 is that fork-shaped is used for the support steel billet, then holing in the middle part of driving lever 7 shafts, the edge cover is sliding to be contained on the axle journal 16, the elongated cylindrical hypomere 13 of driving lever 7 adopts threaded connection to be packed on the shaft and can regulate length as required, this cylindrical hypomere 13 is sliding again to be contained in the vertical through holes 19 of the balance staff 12 on the carrier base 11, carrier base 11 is packed on the built-in fitting of concrete stylobate side, the left side of carrier base 11,

right support plate

18,20 stage casing connecting rod, bolt (not drawing among the figure) joins together, a left side, right support plate 18, the left and right sides axle journal of 20 head perforate edge cover back sliding dress balance staff 12, offer the vertical through holes 19 perpendicular on the balance staff 12 with the center line of left and right sides axle journal, like this along with the continuous rotation of crank 6, driving lever 7 is correspondingly swung, also can move up and down freely simultaneously, the fork-shaped head that this compound motion just can satisfy driving lever 7 is finished the action of steel billet blanking, behind operating personnel's actuating motor 1, several cranks 6 together rotate continuously, drive several driving levers 7 and repeat the compound motion doing positive and negative swing and move up and down, the fork-shaped head of driving lever 7 by predetermined curvilinear motion and continuously the support steel billet steel billet is transferred on the roller-way from feeding skid, accomplish to beat easily and put down gently, avoid the bump of steel billet to roller-way and roller-way side plate, reduce noise widely, improve production environment, and prolonged the service life of equipment.
