Description
Technical field
The utility model belongs to the descaling of steel stock device, particularly a kind of steel billet upper surface descaling mill lowering or hoisting gear.
Background technology
Well-known, round steel billet is mainly used in the blank before the forging and pressing formed product such as hub for vehicle wheel, power transmission shaft, spindle.Along with the fast development of auto industry, the quality and the required precision of forging product are more and more higher, and people also notice the importance that blank is handled in earlier stage when improving constantly the forging forming technology, just will carry out de-scaling to its upper surface.At present, to the de-scaling on round steel billet surface, be in De-scaling box, adopt electric jet mechanism to carry out de-scaling, it is an end that connects high-pressure hose on electric lift, and the playpipe of the other end connecting band nozzle of high-pressure hose is sprayed on the steel billet upper surface with water under high pressure through nozzle and carries out de-scaling.Because the altitude range of steel billet changes greatly, need often to adjust the height of upper nozzle, and top injection equipment water inlet is in the past supplied with by high-pressure hose all, so high-pressure hose will often upper and lowerly move.Bring following shortcoming and defect part thus:
1, the pressure of descaling mill grey water system is that 31.5MPa belongs to high pressure water system, and injection equipment requirement pipeline flow is very big, therefore will select big latus rectum high-pressure hose.All there is lower problem in service life in big latus rectum high-pressure hose both domestic and external at present, needs frequent replacing after moving use repeatedly, has not only caused huge waste but also delayed the production cycle.
2, owing to be subjected to the top injection apparatus often to need mobile the limit, the rigidity of the junction of high-pressure hose and injection equipment is not strong, very easily damages after often moving.
3, because the bending radius of high-pressure hose is bigger, the also very big entire arrangement for the descaling mill structure of its occupation space is also very unfavorable.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, can make the de-scaling of round steel billet upper surface complete, guarantee scale removal effect, can improve service life greatly again, reduced maintenance frequency, economize on the use of funds, and have a kind of very easily steel billet upper surface descaling mill lowering or hoisting gear of handling safety use.
The purpose of this utility model is to adopt following technical scheme to realize: described steel billet upper surface descaling mill lowering or hoisting gear, comprise electric lift, playpipe, De-scaling box, be characterised in that: its structure is by cylinder body, support, hollow piston rod, cylindrical stent, stopping means, cover plate is formed, connect cover plate at the De-scaling box end face, the cover plate end face connects upright cylindrical stent, connect cylinder body on the cylindrical stent inner bottom surface, cylinder base is provided with the water inlet that is communicated with the cylinder inner chamber, cylindrical stent end face installing support, prop up top of the trellis and connect electric lift, the lift bottom connects an end of hollow piston rod, the other end of hollow piston rod passes cylinder body and cover plate stretches out in De-scaling box, hollow piston rod stretch out pipe end and playpipe joins, the stopping means of installing control hollow piston rod adjustable height on the lateral wall of cylindrical stent is distributed with apopore on the cross section of the hollow piston rod section at cylinder body top.
Described hollow piston rod, the cross section of bar upper semisection are solid.
Described stopping means, form by upper limit plate, lower limiting board, travel switch, corresponding with the ascending, descending height and position of hollow piston rod, load onto limiting plate, travel switch in the cylindrical stent outer upper, middle side part loads limiting plate, travel switch outside cylindrical stent.
Described playpipe is elbow-shaped, and Yu Qiguan bottom distributes and connects nozzle more than two, and the angle of its each nozzle and playpipe axis is in α＜15 °.
Principle of the present utility model and operation are described below:
The water under high pressure pipeline that pump works is attracted is connected on the cylinder body, and piston rod inside is hollow, sets out the water hole on it, and is connected with cylinder interior, and the cylinder interior water under high pressure arrives header by hollow piston rod upper water-out aperture hollow water channel and sprays.
Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, compact conformation, can make the de-scaling of round steel billet upper surface complete, guarantee scale removal effect, can improve service life greatly again, reduced maintenance frequency, economized on the use of funds, and had handling safety and use advantages such as very convenient.
