(54) WORKING ROTOR OF THE ROTARY MACHINE

one

The invention relates to the field of metal forming, namely, i working rotors of a rotary machine, designed to perform pressing operations, such as stretching, 5 stamping, etc.

A working rotor of a rotary machine is known, which contains a shaft with a drum coaxially disposed on it, a set of tools, each of which is 10 more complete in the form of dies and punches, a power drive of tools made in the form of a disk inclined to the shaft axis, connected by a guide element detachable connecting rods, made of 15 two parts, each of which is provided with a spherical head, with the head of one part of the connecting rod pivotally mounted in the disk 1.

A disadvantage of the known construction 20 of the working rotor is the high intensity and large dimensions. In fact, this rotor contains a tool holder, two drums, a slide, etc. As a result, its gage 2. rites are quite significant.

The aim of the invention is to reduce the size of the rotor.

This goal is achieved by the fact that the spherical head of another 30

Ty of each rod is pivotally mounted in the drum, with the dies placed in one part of each connecting rod, and the punches in the other.

With such a design, the rotor of the connecting rod, which previously only served to transfer the rotational motion of the swash plate to the translational motion of the sliders, is now –– in one part of the connecting rod, the punch is reinforced, and in the other, the die, and the movement of the part of the connecting rod connected to the disk is directly transmitted to the tool without the aid of sliders. As a result, the proposed rotor makes it possible to exclude the tool holder, tool blocks, one drum, slide blocks from its design, and significantly reduce the dimensions of the height of the second drum. In FIG. 1 shows a working rotor of a rotor machine, a longitudinal section in FIG. 2 and 3 shows enlarged fragments of the section of the rotor connecting rod when performing a technological operation.

The working rotor of a rotary machine contains a shaft 1 with a drum 2 located on it, a tool kit with dies 3 and punches 4 each, a power drive of instrumentation. made in the form of a disk 5 inclined to the axis of the shaft 1, split rods connected by a guide element, each part of each of which is equipped with a spherical head, the head 6 of the connecting rod part 7 mounted on the disk 5, and the spherical head 8 of the other connecting rod part 9 are hinged in the drum 2, while in part 9 of the rod mounted matrix 3, and in part 7 - the punch 4. Part 9 is made in the form of a hollow sleeve, which houses part 7 of the connecting rod so that part 9 serves as a guide for part 7. In part 9 A groove is provided for feeding the workpiece. Shaft 1 is connected with the help of gear 10c driven machines (not shown on Liguri). The rotation on the inclined disk 5 is transmitted by means of gears 11 and 12. The rotor operates as follows When starting the machines, the shaft 1 and the drum 2 come into continuous spin. In this case, with the aid of the Helical Gear, 11 and 12, an inclined disk 5 comes in continuous synchronous rotation. As a result, the connecting rod part 7 is reciprocating in the guide parts. Since both parts 7 and 9 of each connecting rod are hinged and are inside one another, they will always be coaxial. At that moment, when parts 7 and 9 are in a vertical position, and part 7 with a punch 4 is in the lower position, through the groove of part 9 is a transport rotor (in the figures it does not show the blank 13, which is aligned with the punch 4 and the dies 3 Then, as the rotor rotates, the part 7 moves upward under the action of the inclined disk 5 and the punch 4 pushes the workpiece 13 through the dies 3, producing a technological operation of drawing and making the product 14. In the course of part 7 downwards, the 14 is removed from the punch 4 puller (not shown in the figures). 14 are pushed upwards by a column until one of them goes beyond the ball head 8. In this position, when the parts 7 and 9 are vertically arranged, the gripping body of the next transport rotor of the rotary machine (not shown in the figures) is taken away. The production cycle is carried out continuously. The working rotor of the rotor machine according to the invention will make it possible to reduce the dimensions of the rotor while maintaining its efficiency. Thus, comparing with the prototype, the dimensions of the rotor for drawing the glass Kia with the size F8, t l6, t 0.2 decrease 4.5 times. The height of the (total) rotor was 2.0 m, it would be - 0.45 m. The weight was 900 kg, it would be 140 kg. By reducing the weight of the rotor, the power of the drive motor will decrease. By reducing the metal capacity of the rotor and simplifying its design, the cost of its manufacture is reduced. The invention The working rotor of a rotor machine, containing a shaft with a drum located on it, a set of tools consisting of dies and punches, power drive of tools in the form of a disk inclined to the shaft axis of a disk, connected by a guide element connecting rods consisting of two parts, each which are made with a spherical head, with the head of one part of the connecting rod pivotally mounted in the disk, which is different from the fact that, in order to reduce the dimensions of the rotor, the spherical head of the other part of each connecting rod is articulated drum, wherein the matrix -razmescheny in one part of each connecting rod, as punches - to another.
