Description
Technical field
The invention belongs to steel pipe end face process equipment, particularly be applicable to the feed arrangement of a kind of steel tube flat head chamfering machine of pipe end tack and inside and outside chamfered edge.
Background technology
At present; In the steel pipe industry to the tack of steel pipe end face and the steel tube flat head chamfering machine of inside and outside chamfered edge; Its structure comprises cutterhead, spindle motor, main spindle box, feed mechanism and base, and in the flat head chamfering process, its processed steel pipe is fixed; Rotate through spindle motor driving main shaft case inner main axis upper tool pan; The blade that drive is loaded on the cutterhead carries out the flat head chamfering to processed steel, and its feed mechanism comprises that feeding motor, reduction box drive and ball-screw, and driving initiatively through feeding motor, reduction box, the detent ends of leading screw drive main spindle box realizes its feeding; F.F., worker in its tack, the chamfered edge operation advances and rewind down moves by the feeding motor-driven; Because the fast distance of the speed of F.F. and rewind down, the slow distance of the speed that its worker advances is short, and therefore above-mentioned single feeding motor-driven feeding mode has disadvantage and weak point:
1, for satisfying fast feed, just require powerful feeding motor, cause cost high.
2, when transferring the worker to by the F.F. state and advance state, require the feeding motor that sensitive speed responsive will be arranged.
3, accurate to the positioning requirements of F.F. position, otherwise can hit the event of running affairs.Electrical control is required height, bring hidden danger to safety in production simultaneously.
Motor was in extremely low rotating speed state when 4, the worker advanced, and cutting stability is bad, influences product quality.
Summary of the invention
The present invention is intended to the shortcoming and defect part that in said method, exists, and provides not only reasonable in design, and is simple in structure; Both be applicable to fast feed, and be suitable for worker's precession again and do, and it is little to have a power of motor, motor performance is less demanding, stable work in work, and cost is low, handling safety and the feed arrangement that uses a kind of very easily steel tube flat head chamfering machine.
The objective of the invention is to adopt following technical scheme to realize: the feed arrangement of described steel tube flat head chamfering machine; Comprise base, main motor, main spindle box, cutterhead, feed mechanism; It is characterized in that: at electronic, the hydraulic combined feed mechanism of base tail end installing; Described electronic, hydraulic combined feed mechanism by base plate, feeding motor, reductor, supporting base, shaft coupling, bearing block, F.F. hydraulic jack, combination bearing, hollow cylinder bar, guiding feeding chute, tighten up nut, end cap, piston, screw mandrel, nut and screw and form; Connecting axle bearing on the base plate of base tail end end face; In this bearing block, pack into by the screw mandrel of combination bearing supporting; The two ends of described screw mandrel all stretch outside bearing block, screw mandrel is fixed on the bearing block through nut in stretching on the outer screw mandrel of combination bearing lid, continue behind the nut screw mandrel on through the shaft coupling connection by the motor-driven reductor of feeding; The thread segment of the described screw mandrel screw interior with being loaded on hollow cylinder bar is meshed; This hollow cylinder bar passes end cap and is fixed in the piston through tightening up nut; The extension bar bottom face installing guiding feeding chute of described hollow cylinder bar, the cecum of its F.F. hydraulic jack touches with the detent ends of main spindle box mutually; Realize piece precession work through driving the F.F. hydraulic cylinder.
Principle of the present invention, operation and characteristics branch are set forth in down:
Because each processed steel pipe end face is all in identical position; Therefore piece advances apart from being fixed value; The F.F. action realizes that through the F.F. hydraulic cylinder of guiding feeding chute during the main spindle box F.F., the F.F. hydraulic cylinder promotes main spindle box forward and accomplishes F.F. under hydraulic action; And keep the oil liquid pressure in the F.F. hydraulic cylinder, make the position of F.F. hydraulic cylinder keep stablizing motionless.The stroke distances of F.F. hydraulic cylinder is the F.F. distance, avoids hitting the former generation of running affairs.The feeding motor direct connection of the feed system of its guiding feeding chute is on the reductor of supporting base; When the worker advanced, the feeding motor rotated, after power slows down through reductor; Driving screw mandrel through shaft coupling rotates; Screw mandrel is fixed on the bearing block through combination bearing and nut, and screw becomes the rotation of screw mandrel along the horizontal movement of guiding feeding chute, and its horizontal movement passes to main spindle box through the F.F. hydraulic jack and accomplishes worker's precession work.Do because the feeding motor only is used for worker's precession, the range of speeds is little, is in stable duty all the time, and is less demanding to motor performance, and its power of motor reduces greatly.
The comprehensive above technical scheme of being taked realizes the object of the invention.
Therefore, the present invention is not only reasonable in design, and is simple in structure; Both be applicable to fast feed, and be suitable for worker's precession again and do, and it is little to have a power of motor, motor performance is less demanding, stable work in work, cost is low, handling safety with use advantages such as very convenient.
