Abstract

The invention relates to press-forging equipment and can be used to produce bulges at the ends of the blanks, as well as calibration on the outer or inner surface of the blanks or other / f metal forming processes. The aim of the invention is to increase reliability. The goal is achieved by coaxial installation of the power work head, which makes the landing, and the cylinder 6 of the work clamp. When this piston 7 cylinder clamp is made in the form of a glass with an inner conical surface. The clamping jaws IO are made with an outer conical surface and are installed with the possibility of interaction with the piston of the cylinder 6 of the clamp. During operation, the piston 7 of the cylinder 6 of the clamp, sliding its conical surface onto the clamping jaws 10, ensures the clamping of the workpiece 2, the Rod 4 is not connected to the piston 7, therefore, with further movement to the workpiece, it makes a landing. 4 il. 17 7 / n next so 00 00 so so

Description

The invention relates to forging equipment and can be used to produce nodules at the ends of the blanks, as well as for calibration on the outer or inner surface of the blanks or for other metal forming processes.

The purpose of the invention is to increase reliability.

FIG. 1 shows the proposed installation, cut. Original position; figure 2 - the same, the moment of clamping the workpiece; fig.Z - the same, the landing of the clamped workpiece; figure 4 - section

A-A in FIG. I

The device contains a power working cylinder 2 with a piston 3, a rod 4 and a punch 5 mounted in the housing 1. A cylinder 6 for clamping with a piston 7 is mounted coaxially to the power cylinder. The power working cylinder 2 and the cylinder 6 for clamping are rigidly connected to each other. The rod 4 is located in the cavity of the cylinders, ditch; Piston 3 is rigidly fixed at one of its ends, and punch 5 is fixed at the other end. Punch 5 is fastened with nut 8, Piston 7 is filled in the form of a glass with an inner conical surface. A clamping nut 9 is mounted on the clamping cylinder 6. Between the clamping nut 9 and the piston 7 there are placed clamping jaws 10 with an outer conical surface, between which there are elastic elements 11, which serve to separate the jaws 10.

The installation works as follows.

The workpiece 12 is fed into the opening 13. Thereafter, the working fluid under pressure from the pump unit (sounds (not shown) is fed into the cavity 14 through the opening 15. The cavities 16 and 17 are connected to the main drains of the working fluid. The piston 3 under the pressure of the fluid moves into extreme left position, retraction of the piston 7 of the clamping cylinder to the initial position. Under the action of the elastic elements 11, the clamping jaws 10 are pressed against the inner conical surface of the piston 7, providing the necessary clearance for the free flow of the workpiece 12 to the punch 5. In the cavity 17 black Without a hole 18, the working fluid is supplied, while the cavity 14 is connected with the master; at the drain head. Under the pressure of the fluid, the piston 7 of the clamping cylinder moves

with respect to the workpiece 12. Iod, by the action of the conical surface of the piston 7, the clamping jaws 10 clamp the workpiece 2. In this case, the clamping force is transmitted through the power nut 9 to the case of the clamping ciladre 6. (Together with the piston 7, the piston 3 moves as well, and with this, the punch 5 is supplied to the workpiece 12. After the workpiece is clamped 2 by clamping jaws 10, the working fluid is supplied to the cavity 16 through the opening 9. Under pressure of the liquid, the piston 3 together with the rod 4 and the punch fixed on it 5 moves towards the workpiece 12, as a result, a thickening occurs at the end of the workpiece 12. In this case, the force of the landing through the clamping jaws 10 and the nut 9 is transferred to the cylinder bodies 6 and 2. After the operation of the landing, the working fluid is fed into the cavity 14 through o Version 15, with this cavity, the cavities 16 and 17 are connected to the drain line. The stem 4 with the punch 5 is moved away from the product to the stop against the piston 7, after which the piston 7 and the stem 4 move together until they return to their original position. the jaws 10 unclench and release the product.
