Abstract

The invention relates to the processing of metals by pressure, specifically to technological equipment for the manufacture of articles from pipes by rolling, in particular to machines for the running in of pipe ends with a rotary friction tool. The purpose of the invention is to expand technological capabilities and increase productivity. On the same axis of the machine, coinciding with the axis of processing, are installed the headstock 13 with the power head 14 and the back headstock 15 with the power head 16. The power head 14 includes a rail and a gear wheel on which a crimping tool is fixed. The power head 16 is made in the form of a sleeve with a flange and has a sealing tool. The kinematics of the machine provides the following operations: crimping one end of a tubular billet to obtain a bvz spherical surface at the end face and rolling the other end to obtain a toroidal rim. Operations are performed without chip removal due to plastic deformation of the material. 6 Il. SL C

The invention relates to the processing of metals by pressure, in particular to machines for running in pipe ends with a rotary friction tool.

The purpose of the invention is to expand technological capabilities and increase productivity.

Fig, 1 shows the automatic, general view; FIG. 2 shows a section (A-A on Q. FIG. 1; FIG. 3; FIG. 2) FIG. 4, section BB, FIG. 1; FIG. 5, node I in FIG. , 1j in FIG. 6 of the rail 25, which, moving progressively from the camshaft 9 by means of the cam 26 and the lever 28, rotates the gear 29 with the crimping tool 30 attached to it 90, the gluing tool fixed in the head 16, performing the operation roll-in of the rim, has two movements: rotation from the drive 2 through the gear pair 33 and 34 with the aid of a belt drive 32, as well as a quick approach and a working feed from the camshaft 9 through cam 22 and lever

processed on the machine pipe.

The machine contains a bed 1, an electric 524. The rotation of the seaming tool a romechanical drive 2, a hopper 3, with a head 16 is carried out in counters 4 and 5 (FIG. 3) with fixed clamping heads 14 on the opposite side of the silo, Camshaft 9-6 and 7, cam 8, installed, rotates from drive 2, cam shaft 9, lever 10, roller 11.20 Preparations 37 are loaded into the hopper. On one axis coinciding with the axis of position-3, they fall one by one through the window 36 into the machining process 12, the front movable prisms 6 and 7 are fed Leu 4 and 5 are fed by feeders to the machining position, where they are clamped between movable prisms 6 and 7 and fixed prisms 1 38 and 39. After clamping, the force head 14 and the head 16 move. After machining, the feeders 4 and 5 move to the loading position. In this movement of the treatment, the workpiece is dropped from the sub-prism by springs 40 and 41 and falls onto the container (not shown). Then the cycle repeats,

head 13 with power head 14 and (rear head 15 with power head 16 for fastening the seaming tool. 1 has a feed mechanism 21, consisting of a cam 22, a roller 23 and a lever 24. , The back grandma has a belt drive 32, a gear pair of gears 33 and 34. The hopper 3 has a sloping bottom 3.5 and a window for the delivery of blanks 36,

The machine kinematics provides the following operations: crimping one end of tubular billet 37 to obtain a spherical surface without an aperture at the end and rolling the other end to obtain a toroidal edge. For fixation of the blanks, sub-38 and 39 prisms are used, and for their goggling - springs.40 and 41,

Operations are performed without chip removal due to plastic deformation of the material.

The power head 14, which performs the crimping operation, has several movements: rotation from drive 2 by means of a belt drive 31, feed of the head from the camshaft 9 by the cam 18 and the lever 20, the working feed

slats 25, which, moving progressively from the camshaft 9 by means of the cam 26 and the lever 28, rotates the gear 29 by 90 with the crimping tool 30 fixed on it, the gluing tool fixed in the head 16 that performs the operation of rolling the rim, has two movements : rotation from the drive 2 through the gear pair 33 and 34 using the belt drive 32, as well as fast approach and working feed from the camshaft 9 through the cam 22 and the lever

24, the rotation of the seaming tool with the head 16 is performed in the opposite direction relative to the power head 14, the camshaft 9 is rotated by the drive 2, the blanks 37 are loaded into the hopper 3, fall one by one through the window 36

The movable prisms 6 and 7 of the feeders 4 and 5 are fed by the feeders to the machining position where they are clamped between the movable prisms 6 and 7 and the fixed prisms 38 and 39. After clamping, the force head 14 and the head 16, After machining, the feeders 4 and 5 is moved to the loading position, in which case the machining movement of the billet is dropped from the sub-prism by springs 40 and 41 and falls onto the container (not shown). Then the cycle repeats,

For rm ula from gain

A machine for processing the ends of tubular blanks containing an electromechanical drive mounted on the machine, a mechanism for securing the workpiece with movable and clamped prisms, and a headstock with feed mechanism and power head with a crimping tool, different in that capabilities and increased productivity, it is equipped with a rack and pinion gear placed in the power head, a hopper with an inclined bottom and a window of workpieces located above the feeders, and a tailstock with s supply, and a second reverse power head with the seaming tool and zakreplen.- GOVERNMENTAL fixed on the frame prisms, wherein the crimping tool is mounted on the pinion of said rack gear and the movable clamping prisms - at x feeder.
