Description

Double-ended double-station end-flatting machine

Technical field

The present invention relates to a kind of tube end face cutting machines, be specially adapted to that the end face to tubing carries out tack and inside and outside chamfering simultaneously on the tubing continuous processing line.

Background technology

Chamfering machine is the special purpose machine tool that utilizes cutter that the steel pipe end face is processed, all be configured in the Strain During Finishing Stage of steel pipe's production production line, requirement has quite high machining accuracy and rational structure, thereby could satisfy the requirement of whole production line, but the chamfering machine on the present domestic pipe production line mainly contains following three kinds: the one, the manual chamfering machine of original backwardness, its shortcoming is that labor strength is big, productivity ratio is low, can not produce continuously, can only tack, fall the exterior angle, can not fall interior angle; The 2nd, the linked transmission chamfering machine of introduction and imitated Japanese the seventies, this type poor reliability, fault rate height, cost height; The 3rd, some producer was from the chamfering machine of states such as Germany, Italy introduction in recent years, this machine adopts reliable step-by-step movement transmission mechanism, power source adopts hydraulic system, but this type is with high content of technology, once can only process a steel pipe, and process left and right sides both ends of the surface simultaneously, be single head list station, adapt to homemade welded tube unit ability, often be difficult to work owing to the sizing accuracy of steel pipe is not high.

Summary of the invention

The present invention is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide a kind of tack, inside and outside chamfering to process simultaneously to the steel pipe both ends of the surface, can adapt to serialization production, efficient height, low, the easy to operate facing-machine of labour intensity again.This tack function changes with the steel pipe rolling velocity variations, and is not subjected to the influence of steel pipe sizing accuracy, adopts the chamfering machine main frame to be staggeredly placed (double), and each main frame is provided with two unit heads, once processes two steel pipes (double end) simultaneously.

Technical scheme of the present invention is: double-ended double-station end-flatting machine is characterised in that: its structure mainly contains positioning and clamping mechanism, spindle drive case, power set, feed arrangement, stepping transmitting device, step by step structure, main drive, base, lathe bed parts, power transmission shaft, first positioning baffle composition.Step by step structure is housed on the base, each base is equipped with two step by step structure, and every step by step structure links to each other with turning cylinder by shaft coupling, is connected with main drive again, whole equipment has 2 bases, 4 step by step structure and 1 main drive, is used for the automatic carrying of steel pipe and pushes away neat.Positioning and clamping mechanism, spindle drive case, power set, feed arrangement and first positioning baffle etc. are housed on the lathe bed parts, about branch two, be interspersed on the both sides of stepping mechanism, be used for processing respectively the left and right sides both ends of the surface of steel pipe, so be double.The feed arrangement that is contained on the lathe bed has two covers respectively, once can process two steel pipes simultaneously, thus be double end, thus improved production efficiency greatly.

Described positioning and clamping mechanism, by clamping seats (12), guide pillar (13), casing sheet (14), clamp the bar (15) of posting a letter, clamping switch seat (16), upper clamp formwork seat (17), little axle (18), joint (19), location-plate (20), clamping (21), lower clamp formwork seat (22), location post a letter seat (23), location post a letter bar (24), location cylinder (25), clamp cylinder (26), fixture stand (27) is formed, wherein locate cylinder and be contained on the clamping seats, form secondary positioner with little axle, joint, location-plate, location seat, the location bar of posting a letter of posting a letter.Clamp cylinder and guide pillar, casing sheet, clamping post a letter bar, clamping switch seat, upper clamp formwork seat, clamping, lower clamp formwork seat composition clamping device.

Described stepping mechanism, form by little axle (31), mobile tooth plate (32), balancing weight (33), gear-box (34), block (35), belt pulley (36), motor (37), carrying roller (38), shaft coupling (39), its medium and small axle, mobile tooth plate, balancing weight, gear-box, baffle plate, shaft coupling constitute step-by-step system, link to each other with power transmission shaft, main drive by shaft coupling, thereby obtain power, be used to carry steel pipe.Motor, belt pulley, carrying roller are loaded on the gear-box surface, are symmetrically arranged, and have two motors, 4 big small belt pulleys, 8 carrying rollers.Left and right sides direction of motor rotation is opposite, thereby it is also opposite to drive left and right sides carrying roller direction of rotation, is used for the first location of steel pipe.

The present invention compared with prior art has following characteristics: adopt and once process two steel pipes (double end) simultaneously, every alternately processing (double) of steel pipe both ends of the surface, improve productivity ratio greatly, be specially adapted to relatively poor steel pipe tack of sizing accuracy and inside and outside chamfering.Employing secondary location makes that the tack of steel pipe and inside and outside chamfer quality are stable more, efficient.Carry out, adapt to automation, large batch of production line if the upper and lower material stand of cooperation, whole equipment make tack, the chamfering of steel pipe automatically to circulate.
