Abstract

The utility model relates to a rotary cutting disc for cutting pipes and threading, which is characterized in that a sleeve ring drives a worm, a worm gear, an eccentric shaft and a movable cutting disc limited by the eccentric shaft to rotate correspondingly to a fixed cutting disc for changing the diameter of the common tangent circle between the edge tips of four combined threading cutters and pipe cutters. The utility model can implement the cutting pipes and threading processing to the pipes with different diameters, can break the traditional design scheme that the pipe rotates while a cutting holder is fixed, can process long pipes, bent pipes and threads, can automatically cut pipes, and can automatically implement threading, having the advantages of high production efficiency and high processing quality.

Description

Circular cutting disc for cutting tube and threading

The utility model relates to a kind of industry and building pipe arrangement tube-cut wire-sleeving machine circular cutting disk.

Present domestic a kind of electric pipe-cutting threading machine that generally uses, it comprises pipe chuck, roll extrusion cutting knife, mantle fiber screw die, the countersinking cutter of rotation.The pipe and the mantle fiber that can match along the mantle fiber screw die that the tube axis direction moves accordingly of rotation, the cut-out pipe that matches with the roll extrusion cutting knife, reaming is carried out in the reducing that is produced when using the countersinking cutter that pipe is cut off.The shortcoming of this electric pipe-cutting threading machine is, adopts the processing of pipe rotation mantle fiber, and it is not suitable for long tube, bend pipe and the right processing of silk, again because of using the Pipe Cutting of roll extrusion cutting knife also will increase the reaming operation.

The purpose of this utility model is to overcome weak point of the prior art, and a kind of tube-cut wire-sleeving machine circular cutting disk is provided.

This tube-cut wire-sleeving machine circular cutting disk, it comprises the collar, stationary knife dish, movable knife disc, combination tool block, it is characterized in that:

The collar can rotate around the stationary knife dish that is installed on the machine tool chief axis, and determine the angle position of the collar with respect to the stationary knife dish with alignment pin, the worm and worm gear that drives eccentric shaft is installed in the edge of the collar, be installed between the collar and the stationary knife dish by eccentric shaft-driven movable knife disc, combination tool block is rotating shaft with the pivot pin on the stationary knife dish, is connected by slide block mechanism by movable knife disc.Combination tool block is made of tangent die and pipe cutting knife, and the blade tip of 4 combination tool blocks is distributed on public affairs and cuts on the garden.Tangent die fine setting is a leading screw and nut mechanism to cutter mechanism, and pipe cutting knife delivering gear is the shifting block on the headstock of being installed in that is installed in the feed ratchet in the worm and wormwheel eccentric shaft mechanism and stirs that ratchet rotates.

This tube-cut wire-sleeving machine circular cutting disk has been broken through pipe rotation, the fixing traditional design scheme of knife rest, circular cutting disk compact conformation, easy to adjust, easy and simple to handle, automatically Pipe Cutting, automatically mantle fiber again, production efficiency height, crudy are good, can also be fit to the screw thread processing of various reinforcing bars to long tube, bend pipe, silk to processing.Tangent die and pipe cutting knife all can use the incidental emery wheel sharpening of lathe.

Fig. 1 is the tube-cut wire-sleeving machine structural representation.

Fig. 2 a is the circular cutting disk front view.

Fig. 2 b is the circular cutting disk left view.

Fig. 3 is a mantle fiber cutter tool setting position view.

Fig. 4 is pipe cutting knife autofeed schematic diagram.

Now in conjunction with the accompanying drawings, the utility model is further described.

With reference to Fig. 1, circular cutting disk 4 is installed on the main shaft of headstock 1, and pipe 7 to be processed is clamped by chuck 5,6, and the pipe cutting knife feed ratchet 3 that is installed on the circular cutting disk 4 matches with shifting block 2 on being installed in headstock 1, on the headstock 1 with sharpening emery wheel 8.

With reference to Fig. 2 a, Fig. 2 b, the collar 19 drives worm screws 17 worm gears 21 eccentric shafts 18, and the movable knife disc 16 of eccentric shaft 18 constraints rotates around stationary knife dish 15, turns over a certain angle, with elastic positioning pin 20 location.Rotary worm 17 drives eccentric shaft 18 by worm gear 21, and the rotation of eccentric shaft 18 can drive movable knife disc 16 again and rotate with respect to stationary knife dish 15.

With reference to Fig. 2 a, Fig. 2 b, Fig. 3, when rotational lantern ring 19 drives movable knife disc 16 with respect to 15 rotations of stationary knife dish, movable knife disc 16 rotates combination tool block 9 respectively by slide block mechanism 10 drives 4 around the pivot pin on the stationary knife dish 15 14, when if movable knife disc 16 is rotated counterclockwise with respect to stationary knife dish 15, the blade tip of the mantle fiber cutter 12 of combination tool block 9 and pipe cutting knife 13 shrinks to the cutterhead center, otherwise, the blade tip of mantle fiber cutter 12 and pipe cutting knife 13 opens away from the cutterhead center, so change the position of movable knife disc 16 with respect to stationary knife dish 15 corners, can change the mantle fiber cutter 12 of 4 combination tool blocks 9 and the blade tip park diameter of pipe cutting knife 13, therefore can process the pipe of different tube diameters.

With reference to Fig. 2 a, Fig. 2 b, Fig. 4, when Pipe Cutting, the blade tip of the mantle fiber cutter 12 of combination tool block 9 is withdrawed from, the blade tip of pipe cutting knife 13 advances.In circular cutting disk 4 rotary courses, the ratchet 3 that is installed in the circular cutting disk edge is collided with the shifting block 2 that is installed on the headstock 1, stirring ratchet 3 rotates, driving worm screw 17 worm gears 21 rotates, by eccentric shaft 18 movable knife disc 16 is rotated counterclockwise with respect to stationary knife dish 15, pipe cutting knife 13 autofeeds cut off pipe.
