Abstract
The present invention provides a kind of hydraulic rolling machines, including bearing platform, suction device, feeding equipment, drawing mechanism, hydraulic station, electronic crossbeam, polyurethane rubber roller and steel rider, spindle box and overturning frame；Rigid roller in the roller is made of the steel alloy of high hardness high toughness；The steel alloy is prepared using following steps：1）Powdered alloy steel is prepared using aeroponics, added with alloying element C, Cr, V, Mo and W in powdered alloy steel, ball milling mixing is carried out under protective atmosphere, is then dried；2）Mixed-powder is suppressed into steel billet using graphite jig, is sintered.The hydraulic rolling machine of the present invention carries working roll made of the steel alloy of high hardness high toughness, it is not easy to which damage fracture need not be replaced often.
Description
Technical field
The present invention relates to a kind of hydraulic plate shears, belong to machine tool technology field.
Background technology
Veneer reeling machine is a kind of equipment making sheet metal bending forming using working roll, can shape cylindrical member, Tapered Cup etc. no
The part of similar shape is very important a kind of process equipment.The operation principle of veneer reeling machine is outer by hydraulic coupling, mechanical force etc.
The effect of power, makes working roll move, to make plank bend or roll to shape.According to the rotary motion of working roll of different shapes
And change in location, the parts such as oval-shaped piece, arc-shaped workpiece, cylindrical member can be processed.
Veneer reeling machine due to the use of field it is different, type is also different.It is divided into three rolls plate bending machine and four-roller roll bending from roller number
Machine.Three rollers are divided into symmetrical three rolls plate bending machine, three rod veneer reeling machine of horizontal down-regulation type, Curve down veneer reeling machine, upper roller universal
Three rolls plate bending machine, hydraulic numerical control veneer reeling machine.Point mechanical and fluid pressure type from transmission.It is said from the development of veneer reeling machine, upper roller ten thousand
Energy formula is most backward, and horizontal down-regulation type is slightly advanced, and Curve down is highest.
Since the working roll of veneer reeling machine is using frequently, it is easily damaged fracture, affects the use of veneer reeling machine.
Invention content
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of hydraulic rolling machine.
The hydraulic rolling machine of the present invention, including it is bearing platform, suction device, feeding equipment, drawing mechanism, hydraulic station, electronic
Crossbeam, polyurethane rubber roller and steel rider, spindle box and overturning frame；
Rigid roller in the roller is made of the steel alloy of high hardness high toughness；
The steel alloy is prepared using following steps：
1）Powdered alloy steel is prepared using aeroponics, added with alloying element C, Cr, V, Mo and W in powdered alloy steel, under protective atmosphere
Ball milling mixing is carried out, is then dried；
2）Mixed-powder is suppressed into steel billet using graphite jig, is sintered.
The step 2）In, sintering temperature is 1000 DEG C, and soaking time is 5 minutes, and sintering pressure is
55MPa。
The hydraulic rolling machine of the present invention carries working roll made of the steel alloy of high hardness high toughness, it is not easy to which damage is disconnected
It splits, need not often replace.
