Abstract
The present invention provides a kind of two roller rolling machines, including rack, the band retarder motor, bearing block, upper roller, lower roll and the hydraulic system that are connected with rack, the upper roller is driven voller, and the lower roll is drive roll；The upper roller is that rigidity is rolled, and lower roll is flexible roller；The rigid roller is made of the steel alloy of high hardness high toughness；The steel alloy is prepared using following steps：1）Using 14CrODS alloyed powders as raw material, mechanical alloying mixed processing is carried out together with Y203；Make protective atmosphere with high-purity Yun gas, ball milling obtains alloy steel powder；2）The mechanical alloying powder of acquisition is sintered；3）Sintered body is forged, is then made annealing treatment.Two roller rolling machines of the present invention carry 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 two roller rolling machines, 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 two roller rolling machines.
Two roller rolling machines of the present invention, including rack, the band retarder motor, bearing block, upper roller, the lower roll that are connected with rack
And hydraulic system, the upper roller are driven voller, the lower roll is drive roll；The upper roller is that rigidity is rolled, and lower roll is soft
Property roller；
The rigid roller is made of the steel alloy of high hardness high toughness；
The steel alloy is prepared using following steps：
1）Using 14CrODS alloyed powders as raw material, mechanical alloying mixed processing is carried out together with Y203；It is protected with high-purity Yun gas
Atmosphere, ball milling obtain alloy steel powder；
2）The mechanical alloying powder of acquisition is sintered；
3）Sintered body is forged, is then made annealing treatment.
Preferably,
The step 3）In, sintering pressure is 50 Mpa, and sintering temperature is 1100 DEG C.
Two roller rolling machines of the present invention carry 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.
Specific implementation mode
Embodiment 1
