Description
Technical field
The present invention relates to a kind of flat roll finishing mill for processing steel cylinder pipe, belong to the manufacturing technology field of high-pressure bottle.
Background technology
At present, known processes process with steel billet making steel cylinder pipe is that steel billet is heated, put into punching hydraulic press die, with jumper bar obstructed round counterbore of steel billet centre punch is formed the punching base, the punching blank outer surface is also circular, at once the punching base is put into pulling machine material feeding platform again, the push rod of pulling machine inserts in the punching base, at punching base front-axle beam pulling mould bases and device for discharging are installed, can lay multiple tracks ring mould bases and roller die frame above it, the push rod of band punching base is under the promotion of main water vat, make the punching base fast by ring mould bases and roller die frame, it is rolling that the punching base of high temperature is carried out the axial pulling of multi-pass, thereby process the steel cylinder pipe of end cap, and the internal diameter of body is determined by the push rod external diameter, external diameter and wall thickness are determined by ring mould and roller die, be installed in the device for discharging closure of ring mould bases and roller die frame back, push rod rollback under the pulling of main water vat is deviate from the steel cylinder pipe of moulding from push rod, finishes steel cylinder pipe processing.But, steel cylinder pipe wall unevenness, the surfaces externally and internally roughness of this technology mode processing are poor, and when push rod is thrown off from steel cylinder pipe, push rod and steel cylinder inner surface additional are puted forth effort greatly, and it is big to instrument push rod outer surface damage to take off rod, pull out the steel cylinder inner surface quality that the push rod of lateral road surface damage processes and reduce, in addition because push rod is non-rotary when each pulling, push rod pulling work repeatedly, easily to a certain direction bending, the whole form and position tolerance of the steel cylinder pipe that crooked push rod processes reduces.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, can improve steel cylinder inner and outer round surface quality and wall thickness accuracy, reduce push rod and make power, the flat roll finishing mill for processing steel cylinder pipe that when reducing to take off rod instrument push rod outer surface is damaged with the steel cylinder inner surface additional.
The present invention is a flat roll finishing mill for processing steel cylinder pipe, it is characterized in that comprising sole plate, places the last flat roll assembling on sole plate top, places the flat roll assembling of duplex of sole plate bottom; Describedly flat roll assembling and connected and composed by bearing by the hold concurrently flat roll two ends of the roller base of going up guider and band Hooks coupling universal coupling of band top roll hoist cylinder and hole shape adjustment, the flat roll assembling of described duplex is connected and composed by bearing by the hold concurrently flat roll of duplex roller base and band Hooks coupling universal coupling of guider down of band duplex roll hoist cylinder and hole shape adjustment; The push rod of band push rod aft mount places between the flat up and down roll on the pulling machine.
Double upward guider of described hole shape adjustment and hole shape adjustment are held concurrently, and guider can be by the lead that places band round nut in the sole plate down, the limiting plate and the limited block that place between round nut and the sole plate and be sheathed on the lead constitute, fixedlying connected with the roller base of last flat roll assembling in the double lead bottom of going up on the guider of hole shape adjustment, fixedlys connected with the duplex roller base of the flat roll assembling of duplex in the lead top under the hole shape adjustment is held concurrently on the guider.
One side of described sole plate also can be provided with the push pedal of band steel cylinder thruster oil cylinder, and what opposite side was provided with that the band steel cylinder extracts oil cylinder pulls out the material arm.
Described Hooks coupling universal coupling can link to each other with the roll driving motor by reductor.
Described flat roll can be 3～8 distributions at the periphery of push rod.
Also can be arranged with the guiding copper sheathing between described lead and the sole plate.
Also can be provided with the aligning antifriction bearing of band push rod afterbody gland between described push rod and the push rod aft mount.
The present invention is directed to existing pulling machine and make steel cylinder pipe finished product wall unevenness with steel billet, the defective of surfaces externally and internally roughness difference, after tradition is made the pulling machine device for discharging of steel cylinder pipe with steel billet, before push rod is deviate from from steel cylinder pipe, plain-barreled roll finish rolling equipment is set, by 3～8 flat roll rotations that are distributed in the push rod periphery and can cover steel cylinder pipe length, and close up to rolling centerline together, form and the pairing pass of steel cylinder nominal outer diameter, this pass is that the adjusting device accurate adjustment by separately forms, the pass that flat roll forms can be to be made of 3～8 flat rolls that are distributed in the push rod periphery, and guarantee that the pass center is concentric with pulling machine center line, rotatable structure is adopted in the supporting of the machine of pulling simultaneously push rod afterbody, push rod can rotate with steel cylinder pipe in the operation of rolling, and participate in rolling to the equal wall of steel cylinder pipe, 3～8 pulling machine push rods that are distributed in push rod rotatable flat roll of periphery and the steel cylinder pipe form the equal wall of steel cylinder pipe wall thickness rolling, can improve steel cylinder inner and outer round surface quality and wall thickness accuracy, reduce push rod and steel cylinder inner surface additional and make power, when reducing to take off rod instrument push rod outer surface is damaged; Because push rod rotates, and push rod is unfixing in circumferential locations during at every turn to the pulling of punching base, push rod just is not easy can improve the push rod life-span to a certain direction bending in addition.
