Description
Technical field
The invention belongs to the Steel pipe end surface process equipment, particularly be applicable to the feed arrangement of a kind of End-facing/chamfering Machine For Steel Tubes of pipe end tack and inside and outside chamfered edge.
Background technology
at present, at Steel Tube Industry to the tack of Steel pipe end surface and the End-facing/chamfering Machine For Steel Tubes of inside and outside chamfered edge, its structure comprises cutterhead, spindle motor, main spindle box, feed mechanism and base, in the flat head chamfering process, its processed steel pipe maintains static, rotate by spindle motor drive shaft case inner main axis upper tool pan, drive is loaded on blade on cutterhead and carries out flat head chamfering to processed steel, its feed mechanism comprises the feeding motor, reduction box drives and ball-screw, by the feeding motor, reduction box drives initiatively, and the detent ends of leading screw drive main spindle box realizes its feeding, its tack, F.F. in the chamfered edge operation, work is advanced, move by the feeding motor-driven with rewind down, because the fast distance of the speed of F.F. and rewind down, the slow distance of the speed that its work is advanced is short, therefore above-mentioned single feeding motor-driven feeding mode has following shortcoming and defect part:
1, for satisfying fast feed, just require powerful feeding motor, cause cost high.
2, when transferring work 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 the pipe accident can occur.High to the electrical control requirement, bring hidden danger to safety in production simultaneously.
When 4, work is advanced, motor is in extremely low rotating speed state, and cutting stability is bad, affects product quality.
Summary of the invention
The present invention is intended to the shortcoming and defect part that exists in said method, and provides not only reasonable in design, and is simple in structure; Both be applicable to fast feed, and be suitable for again the work precession 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 use a kind of feed arrangement of End-facing/chamfering Machine For Steel Tubes very easily.
the objective of the invention is to adopt following technical scheme to realize: the feed arrangement of described End-facing/chamfering Machine For Steel Tubes, comprise base, main motor, main spindle box, cutterhead, feed mechanism, it is characterized in that: electronic in the installing of base tail end, hydraulic combined feed mechanism, described electronic, hydraulic combined feed mechanism is by base plate, the feeding motor, reductor, supporting base, shaft coupling, bearing block, the F.F. hydraulic jack, combination bearing, hollow cylinder bar, guiding feeding chute, tighten up nut, end cap, piston, screw mandrel, nut and screw form, connecting axle bearing on the base plate of base tail end end face, pack in this bearing block by the screw mandrel of combination bearing supporting, the two ends of described screw mandrel all stretch outside bearing block, by nut, screw mandrel is fixed on bearing block on the screw mandrel that stretches outside the combination bearing lid, continue after nut screw mandrel on connect by the motor-driven reductor of feeding by shaft coupling, 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 piston by 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 mutually with the detent ends of main spindle box, realize piece precession work by driving fast inlet hydraulic cylinder.
Principle of the present invention, operation and characteristics are described below:
Due to each processed Steel pipe end surface all in identical position, therefore piece advances apart from being fixed value, fast forward action realizes by the fast inlet hydraulic cylinder of guiding feeding chute, during the main spindle box F.F., fast inlet hydraulic cylinder promotes forward main spindle box and completes F.F. under hydraulic action, and keep the interior oil liquid pressure of fast inlet hydraulic cylinder, make the position of fast inlet hydraulic cylinder keep stablizing motionless.The stroke distances of fast inlet hydraulic cylinder is the F.F. distance, avoids the generation of pipe accident.The feeding motor straight of the feed system of its guiding feeding chute is associated on the reductor of supporting base, when work is advanced, the feeding electric machine rotation, after power slows down through reductor, driving screw mandrel by shaft coupling rotates, screw mandrel is fixed on bearing block by 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 by the F.F. hydraulic jack and completes work precession work.Do because the feeding motor only is used for the work precession, the range of speeds is little, is in all the time stable duty, and is less demanding to motor performance, and its power of motor reduces greatly.
The comprehensive above technical scheme of taking realizes purpose of the present 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 again the work precession 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 use the advantages such as very convenient.
