Pipe cutter

Technical field:

The utility model relates to a kind of machine that is used to cut pipe, belongs to pipe cutter and makes the field.

Background technology:

Existing pipe pipe cutter, on structural design, the pitch cutting of motor drives emery wheel.During cutting, pipe is inserted on the pipe cutter knife rest, open motor, motor drives emery wheel and depress downwards and cut.Not enough point: the one, the mouth of pipe that is cut produces distortion, and fineness is poor; The 2nd, can't be used for pipe (Plastic Steel Pipe) production line.

Summary of the invention:

Purpose of design: avoid the weak point in the background technology, design and a kind ofly can either guarantee that the pipe otch is indeformable, fineness good, again can with the supporting pipe cutter of pipe train.

Design: 1, main shaft is designed to have the hollow shaft of screw thread and is provided with blade feed mouth on hollow spindle, and the two ends of hollow spindle are bearing on the frame by bearing.The purpose of hollow spindle is: guarantee that the pipe cut can pass in it.The purpose that is provided with screw thread (screw thread) on main shaft is: can guarantee the driver plate move left and right by the screw thread rotation thereon.Main shaft by sprocket wheel fixed thereon, chain by motor drives.2, be provided with relative clamping device and be complementary at the two ends of hollow spindle with hollow spindle, clamping in the clamping device or unclamp by cylinder and control, cylinder is controlled by electric control box, and the sample of signal of electric control box derives from two travel switches, and the trip switch machine of being fixed on adds to be wanted and triggered by driver plate.3, the knife rest assembly rotates synchronously with main shaft, and the rotation mouse cage that drive to slide rotates synchronously with main shaft, but move left and right not.The knife rest assembly is adjusted guide rod by blade, roller, the depth of cut and is constituted, and blade is positioned at the depth of cut to be adjusted the guide rod end and be controlled by the depth of cut and adjust guide rod, and the depth of cut is adjusted guide rod and is positioned at knife rest roller assembly, and its tail end matches with arc guide barrel in the guide rail.What or the deep-slotted chip breaker radian that withdraws from by squirrel-cage swiveling wheel middle guide of the depth of cut are determined.4, slide the rotation mouse cage by the drive of the slide bar in knife rest assembly rotation synchronously, and constitute in the effect lower edge of driver plate slide bar move left and right and by cutterhead, guide rail, the two ends of guide rail connect two cutterheads (18).

Technical scheme 1: pipe cutter, the two ends that have the main shaft (3) of screw thread are positioned on the frame by bearing (2), two clamping devices (1) lay respectively on the frame at main shaft two ends and drive clamping device by cylinder (12) and clamp or unclamp, knife rest roller assembly (6) is enclosed within on the main shaft and with main shaft and is solidified as a whole, it is affixed and drive slide rotation mouse cage and main shaft and rotate synchronously with the godet that is enclosed within the slip rotation mouse cage (4) on the main shaft respectively that slide bar (17) passes its two ends of knife rest roller assembly (6), along the slide bar move left and right, be rotary with driver plate (9) on the main shaft of position slip rotation mouse cage one end, one is equipped with sprocket wheel (15) in addition, sprocket wheel (15) drive to be rotated by motor (13) by chain, and driver plate (9) matches with two travel switches (11) on being positioned at frame and controls advancing of driver plate or move back by electric control box.

Technical scheme 2: the cutting method that cuts off machine, as described in claim 1～4, pipe is through in the main shaft and clamped device clamps, motor drives the sprocket wheel rotation by chain, sprocket wheel drive main axis rotation and the knife rest roller assembly that is fixed on the main shaft rotate synchronously, be through that slide bar in the knife rest roller assembly drive to slide that the rotation mouse cage rotates synchronously with main shaft and under the effect of driver plate, when main axis rotation, screw thread in the driver plate and the screw thread on the main shaft form the motion that spins forces the rotation mouse cage that slides to move to right along slide bar, deep-slotted chip breaker in the guide rail on the slip rotation mouse cage forces the depth of cut that is positioned at it to adjust guide rod and promotes the blade feed, cut off pipe, after pipe cuts off, driver plate touches mutually with travel switch, feed stops, motor reverses and passes through chain, sprocket wheel drive main shaft and the knife rest roller assembly that is fixed on the main shaft reverse synchronously, driver plate forces the rotation mouse cage that slides to move to left, deep-slotted chip breaker in the guide rail forces the depth of cut that is positioned at it to adjust guide rod and promotes the blade withdrawing, this moment, cylinder unclamped clamping device, can take out the pipe after the cut-out.

The utility model is compared with background technology, and the one, the design of hollow spindle, the enterprising edge of a knife of hollow spindle and clamping device has guaranteed that pipe can enter automatically to be cut the place, and is clamped automatically, be cut; The 2nd, the design of the rotation mouse cage that slides, it is motionless not only to have realized being cut pipe, cutter is moving, and realized automatic cutting, the automatic withdrawal after having cut; The 3rd, the design of knife rest assembly has not only realized by the Pipe Cutting rim of the mouth indeformable, smooth smoothly, and can be complementary with pipe train; The 4th, structural design novelty, uniqueness, simple, practical; The 5th, can be supporting with pipe train, can be used as a separate equipment again and carry out work; The 6th, the knife rest assembly with slide bar in main shaft rotation synchronously and the knife rest assembly drive slide the rotation mouse cage with main shaft rotate synchronously, the structural design of move left and right, solved the stuck technical barrier of blade in the rotation cutting, made structure of the present utility model simple more, practical, effective.
