Description

Pipe cutting machine

Technical field

The present invention relates to pipe cutting machine, particularly the incisory cutting machine of tubing intersection.

Background technology

In shipbuilding, construction and installation, chemical industry, oil, machinery, metallurgical tube frame structure and other tubular structure spares cutting processing, have a large amount of intersections hole, intersection termination, elbow to need processing, this type of processing adopts the numerous and diverse methods of backwardness such as artificial setting-out, manufacturing model, blanking line, artificial cutting, artificial polishing to carry out mostly.At present, the domestic pipe cutting equipment that passes through mutually mostly is numerical control and passes through tube cutting machine mutually, it is higher that the tube cutting machine sharpnes of cuts is passed through in numerical control mutually, production efficiency is also high, but tube cutting machine is passed through in numerical control mutually weak point is arranged also, the cutting mode that adopts when mainly being cutting is the workpiece rotation, and cutting torch takes the air line, like this, can only carry out the straight tube cutting.Will add the pipe bracket track in addition, can not arbitrarily move, can't finish the cutting processing as bend pipe and semifinished part, the scope of application is restricted.And during its single-piece cutting processing owing to will carry out numerical control programming, make process more numerous and diverse.Its equipment cost is very high in addition, and domestic general medium-sized and small enterprises do not have ability to buy.

Summary of the invention

The technical issues that need to address of the present invention provide and a kind ofly do not need to carry out numerical control programming, and can process bend pipe, semifinished tube, and cutting is stable, accurately, production efficiency height, the cutting machine that equipment cost is low.

Technical scheme of the present invention adopts guiding lathe bed, main spindle box, cutting torch, the liftable rotation bench vice that spur rack is housed, main spindle box is arranged on the lathe bed upside, main spindle box is equipped with and the lathe bed spur rack that leads assembles worm gear, worm screw, handwheel, dress driving motor in the main spindle box, bench vice is contained in the front end of guiding lathe bed; The lathe bed the right and left that it is characterized in that leading is provided with straight guide, and the slide block that cooperates with the lathe bed left and right sides straight guide that leads is equipped with in the main spindle box bottom; The driving motor of main spindle box is by being with interlock rolling spline main shaft synchronously, and the rolling spline main shaft passes main spindle box; The front end of rolling spline main shaft is minor leading screw fixedly, minor leading screw other end dress cutting torch support, and the cutting torch bracket end is cutting torch fixedly; The rolling spline rear-end of spindle connects an adjustable eccentric plate, and scale is arranged on the eccentric disk, and eccentric disk connects cruciform joint; Be provided with shape cutting governor motion at guiding lathe bed afterbody, shape cutting governor motion is by rocking bar, guide rail, scale, screw mandrel, counterweight is formed, the mobile screw mandrel parallel with main shaft is equipped with in the main spindle box bottom, mobile screw mandrel end is equipped with the rotating disk holder, the rotating disk holder is connected with dial rotation, rotating disk is provided with fixed axis, the fixed axis two ends are provided with linking arm, the rocking bar of shape cutting governor motion is fixed on the linking arm, the rocking bar two ends are parallel body, and be provided with scale, can add counterweight on the rocking bar, the rocking bar disk center that can rotate shakes, and screw mandrel is connected with guide rail and is fixed on the rocking bar, rocking bar is vertical with screw mandrel, and shape cutting governor motion connects the cruciform joint that is connected with eccentric disk by the guide rail sliding sleeve.

Because the rolling spline pair that the present invention adopts is a kind of linear motion system, when spline housing utilization steel ball wherein through on the splined shaft of accurate grinding during rectilinear motion, can transmit moment of torsion, can transmit the load and the power that exceed the quata, can be with the clearance control of direction of rotation to the zero clearance or interference, compact conformation, and the long life-span is arranged; Adopt the lever principle machine driving, the cutting that is shaped is by the control of shape cutting governor motion, and the operator need not programme, and can directly adjust fitness, gradient and non-concentricity; Processed pipe workpiece does not rotate, and by the bench vice rotation, just can carry out the intersection at pipe two ends, the processing in hole, and the cutting curve fairing is correct, and otch is neat, and fineness meets the cutting standard, can guarantee the quality requirement of erection welding.And intersection, hole and pipe end, the processing of " dried shrimp joint " elbow that can also cut bend pipe and semi-finished product pipe fitting.Equipment cost is only passed through 1/5th of tube cutting machine mutually for numerical control.
