Description

(Reg. 2

The invention relates to equipment for the processing of composite materials and can be used in various fields of the national xoosncTBj in the manufacture of tubular products.

The purpose of the invention is to simplify the device instructions.

FIG. 1 shows the device, a general view; in fig. 2 — knot 1 for fastening the centering rod and control rails; in fig. 3 is a view of L in FIG. 1.

The device for removing pipes from the mandrels consists of a base 1, on which lodgments 2 for the mandrel Z are rubbed, the headstock 4 and the back headstock 5, with ree: L in it, the drive of the chamfer C, perched on the rail 7, stop r - „/ ring 8 and lodgments for the pipe 3 removed from the mandrel (not shown).

On the carriage 6, there is a device for gripping the mandrel 3, which is a housing 9 with the cams 10 that are mounted on it in the horizontal plane and interacting with the stop shoulder of the mandrel 11 of the mandrel 3 and the gears 12 pressed to its ocvi in the radial direction by the hook 13, which is engaged with the 9 centering rod 14 which is movably mounted in Kopnvr.s 9 and the toothed turn of the control 15.

The device for semete pipes with opragi: j equipped with two stops 16 and 17, a mustache; r one on the stop ring 0,) on the tailstock 5 in the extreme position of the carriage 6 and interacting alternately with the toothed rack S5 control.

The device for removing pipes from mandrels 3 works in the following manner.

The mandrel 3 with the tube formed on it is mounted on the cradle 2. The center of the headstock 4 holds the mandrel, 3 presses against the stop ring 8. At the same time, the tailings 11 of the mandrel 3 protrude through the hole of the stop ring 8, and the pipe removed from the mandrel 3 rests on it. The carriage drive b, located in the tailstock 5, is turned on and the carriage b is moved along the guides 7 to the stop ring 8 up to the stop of the kupachka 10 into the shank 11 of the mandrel 3. As the carriage 6 continues to move, the cams 10 are pressed

and automatically sprinkled over the stop Surgean of the hossuvik 1 oprlvkm 3. At this moment, the gear bar of the 15th control rests against the fixed on the retaining ring 8

the stop 16 begins to move towards the rear section 5. The rail 15 moves the cogwheel wheel 13 and the tangled ipang I, which enters the end hole of the shank 11 of the mandrel 3, to ensure its horizontal position. After that, a command is given to the drive, which begins to move the carriage 6 in the opposite direction. At the same time, the cams 10, abutting against the bead of the tailing 11 of opraoksm 3, pull it out of the pipe abutting against the stop of the pipe.

B hp.T i ieri the right position of the stroke of the carriage 5 tines ryyka 5 control, rising in pore 17, leads out of the tail 1

the mandrel 3 centering rod 14. Mandrel 3 under the action s (GM of its own weight is lowered. Removing the pipe 3 from the mandrel tube 2 is fed into the drive. After that, the cradle 2 returns to

the former place and they place the next mandrel 3 with the pipe. The cycle is repeated. Thus, the proposed device for removing tubes with mandrels is characterized by simplicity, which, in turn, simplifies
