Description

one

The invention relates to the field of metal forming and can be used for the manufacture of articles from tubular blanks, for example for the manufacture of bottoms with bottoms and necklining.

The known machine for rolling the tubular blanks containing a frame, mounted on it a shaft with a drive, two axially mounted on the drive shaft of the drum, one of which houses loading mechanisms made in the form of a copy sleeve and interacting with it rollers, and on the other their corresponding spindles, as well as the forming tool.

However, this machine has large drum dimensions with loading mechanisms.

The purpose of the invention is to reduce the size and the ability to load blanks in a convenient area of the technological space, i.e. in a convenient area around the circumference of the loading drum.

This is achieved by the fact that the copier bushing is loosely mounted on the drive shaft. In this case, the taper groove is made on the outer surface of the copier bushing, which can be equipped with an end disc with holes, which include a cap that is rigidly connected to the frame.

FIG. 1 shows the proposed car, front view; in fig. 2 - the same, top view; in fig. 3 is a section along A-A in FIG. 2; in fig. 4-section along BB in FIG. 3

An axially rotating drum 2, on which loading mechanisms 3 are mounted, and a drum 4, on which shnindles 5 are similarly mounted, are mounted on the machine base 1. The rotational drive of the drums consists of engines 6, gearbox 7 and gear pair 8, which transmits torque to drum common shaft 9.

The loading device consists of a copy sleeve 10, mounted ovo-baud on the drive shaft 9. In order to prevent the copy sleeve 10 from turning on the frame, a UiR is rigidly fixed, which is connected to the copy sleeve 10 by means of a pin 12, which is inserted in the hole on the disk 13. Loading

the drum 14 is rigidly fixed to the drive shaft 9. On the loading drum 14 grooves are made, along which the pushers 15 move. The pusher 15 is connected to a copy roller 16, interacting

with the groove of the copier bushing 10, and the pushers 15 are mounted coaxially with the spindles 5.

The molding tool 17 is reinforced in a tool holder located between

reels 2 and 4.

In addition, the pusher 15 has a safety device 18 mounted on the bearing unit 19.

The loading of the machine with billets with heated ends is carried out alternately with each loading mechanism 3 at the moment when the drums 2 and 4 are loaded.

In the steady-state operating mode, the loading drum 14, together with the pushers 15, performs a uniform rotation around the axis of the drive shaft 9, while the copier sleeve 10 remains stationary. .

The preheated end blank is loaded into the groove of the feed drum 14 at the time when the pusher 15 is in the leftmost position. Copy roller 16, moving along the groove of the caper drum, will lead to the right the pusher 15, which sets the workpiece in the spindle 5.

To reduce the friction of the workpiece on the spindle, the pusher, 15 is equipped with a safety gear 18 mounted on the bearing assembly 19.

After completion of the workpiece task in the spindle 5, the pusher 15 is in the extreme right position until the workpiece is clamped in the spindle, after which the pusher 15 moves to its original position.

Clamped in the cartridge, the workpiece continues to move along with the drum 4 around the circumference, simultaneously rotating around its axis. On its way, the billet encounters a fixedly mounted forming tool 17. As it passes along the working surface of the latter, the heated end of the billet during the friction friction process deforms from the initial to the final shape.

If necessary, load the workpiece in

different zones of the process space, the copier sleeve 10 rotates around the drive shaft 9 at a certain angle, with the stop II using pin 12

is disengaged from the roller drum 10, and then inserted into a new groove on the disk 13 to fix the new position.

The proposed machine allows to reduce the dimensions of the drum containing the loading mechanisms by 1.5 times, since the execution of the copier allows communication of the loading mechanisms with the copier inside the drum containing the loading mechanisms and makes it possible to turn the drum if

It is necessary to load the workpiece in any zone of the technological space without disassembling the machine.

Claims (2)

1. A machine for rolling in tubular blanks containing a frame, a shaft with a drive mounted on it, two axially mounted on a drum drive shaft, one of which has loading mechanisms made in the form of a copy sleeve with a groove and rollers interacting with it, and on the other - corresponding spindles, as well as a forming tool, characterized in that, in order to reduce dimensions and ensuring the possibility of loading the blanks in a convenient area of the technological space, the copier bushing is freely mounted on the drive shaft, while the copier groove of the bushing is made on its outer surface. 2. The machine according to claim 1, differing from the fact that the copier sleeve is provided with an end disk with holes, which include a pin rigidly connected to the frame. / v v "t-x K & xg ...
