SU1234028A1 - High-speed hammer - Google Patents

Description

the working position, the upper half of the punch forms with the lower half of the punch a closed cavity for making stamping.

On command from the hammer drive, fluid is supplied simultaneously to the piston cavity of the cylinders 21. The rods 22, moving in the direction of the crosshead 8, mix the stops 20, which additionally press the crosshead 8 with the upper half of the 14 punch

The invention relates to mechanical engineering, namely, to forging equipment.

The purpose of the invention is to improve the quality of products manufactured on a high-speed hammer by preventing the traverse from rebounding.

The drawing shows the proposed high-speed hammer.

The high-speed hammer contains a frame 1, in which on an elastic base 2 (O to the punch half of 15.) After that, frame 3 is closed with a power unit, the blank cavity is loaded into the workpiece 23. By

at the top of the last. The power unit is made in the form of a receiver 4 and a power cylinder 5, the piston of which is connected to a crosshead 8 by a hollow rod 7 mounted in the die space 9 of the hammer in vertical directions 10 of the frame 4. In the cavity of the rod 7 a woman 11 is placed with a punch 12 at its end. A mechanism 13 is provided for holding the female 11 in the upper position. On the traverse 8 JQ, the inertial forces are transmitted to the half 15 on the side of the rod 7, the bevels are made, and the stamp, the upper half of the 14 stamp is fixed to the bottom. The lower half of the stamp 15 is mounted on the shtampa plate 16 of the table 17, in which the ejector 18 is mounted with a drive from the hydraulic cylinder. 25 each is retracted. After the sides of the frame 4 in horizontal directions, this fluid from the cavity of the piston 6 under

19 mounted stops 20 with tilt-action gas pressure are displaced into

working surface and horizontal hydraulic tank. In this case, the piston 6 with the rod 7

No support surface. The stops 20 in the upper half of the punch 14 are lifted by the executive elements of the fur-up, and the punch 12 presses the stamping of the crosshead, which is driven by 30 billet to the half of the 15 stamp, which are the hydraulic cylinders 21 connected After the clearance S has been selected, the crosshead 8 with its stocks 22 with stops 20. grabs the shoulder of the woman 11 and tears off

Position 23 denotes the initial punch punch 12 from the stamped billet, goods. When the piston b reaches the initial high-speed hammer, the following command is applied to the mechanism 13. The command W.I. on the clutch with the female 11. After that, the hydraulic pusher is pushed into the cavity above the piston by the command to the ejector 18 to remove it from the lower cavity under the pressure of the working liquid stamped billet. Overcoming gas resistance of 15 punch. The cycle repeats, in receiver 4, the piston 6 with the rod 7. The economic effect of introducing isobravers 8 and the upper half of the 14th Q-retente is ensured by increasing the quality of the stroke in the working position. In va products.

a command from the hydraulic drive to the mechanism 13 for gripping and holding the female 11 is supplied with liquid, under the action of which the female 11 is disengaged.

Under the pressure of the gas of the receiver 4 Baba 11 with a punch, 12 makes a working stroke and with its mass hits the initial billet 23, the metal of which fills the closed cavity. Arising

After completion of the process of deformation of the original billet 23, the liquid from the hydraulic actuator of the hammer is supplied to the rod end of the cylinders 21 and the stops 20.

 to half of the 15th stamp. After that, the blank 23 is loaded into the closed cavity.

The inertial forces are transmitted to half of the 15 punch, retracted to their original position. After that, the fluid from the cavity of the piston 6 under
