Abstract

The invention relates to the processing of metals by pressure, in particular to mechanisms that ensure the piece-by-piece feeding of blanks into the working zone of the press. The purpose of the invention is to expand the technological capabilities of the device and increase its reliability in operation. The rod 1 moves the body with movable jaws above the die plate along which the workpiece slides. Having reached the stamped product, the sponge pushes it from the stamp mirror. When the billet cylinder is aligned with the center of the stamp, the housing reaches the fixed stops 12 and stops. The stock continues to move forward. The ball 5 is squeezed out of the locking groove. The rod moves to the distance L and stops with the support 13. The ball 6 falls into another groove and fixes the jaws in the open position, since rake opens them up to a given value. When the body moves backwards, the billet remains in the center of the stamp, the sponges open and close when the guides of the body 15 reach the rear stops 14. The device automates the technological process in the forging and stamping industry. 1 il.

The invention relates to the processing of metals by pressure, in particular, to mechanisms that ensure the single-piece supply of blanks to the working area of a press, i. The aim of the invention is to expand the technological capabilities of the device and increase its reliability.

The drawing shows the device, (BS, I view.

The rod 1 mixes the housing with movable jaws above the die plate along which the workpiece slides. The device contains movable jaws 2, which are connected to sectors 3, mounted on axles 4. The end of the stem is made in the form of a toothed double-sided plane (I. There are grooves under the fixing balls 5 and 6 on the rod. Pistons 7, which hold the balls, are supported by the spring-and-8, the force of which is regulated by the plug 9. On the case 10 there are two) adjustable stops 11, which limit the stroke. The stationary front stops 12 are mounted on the die-plate mirror. The stop 13 on the stock limits QiTOKa forward travel. The fixed rear stops 14 are mounted on a feed drive. The rods 15 are fixed on the body on two sides.

I The device works as follows. I In the initial position of the mechanism, a blank is laid in the closed jaws. The rod 1 moves the body with movable jaws over the die plate along which the workpiece slides. Having reached from the stamped product, the sponge pushes it from the stamp mirror. When the cylinder of the workpiece is aligned with the center of the stamp, the body; reaches movable stops 12 and left; is poured. The rod continues forward movement; the ball 5 is squeezed out of the fixing groove;

pushes the distance e and stops by abutment 13 into the feed housing. The ball 6 falls into another groove and fixes the jaws in the open position, as the rail opens them to a predetermined value. When the body moves backwards, the billet remains in the center of the punch, the jaws continue to remain open and close when the guides reach the rear stops 14. In the initial position, the mechanism with the closed jaws is loaded with a new billet.

Claims (1)

Invention Formula A device for feeding piece blanks containing sponge-mounted sponges for gripping the billet, toothed sectors fixed on the axes and rigidly connected with the jaws, jaw movement actuator made in the form of a rod connected to the feed drive installed in the center of the case and at the end which made gear elements with the possibility of interaction with gear segments, characterized in that, in order to expand the technological capabilities of the device and increase the reliability of its operation, it is equipped with guides mounted in the housing, the axes of which are parallel to the stem, and stops mounted on both sides of the housing with the ability to interact with the end surfaces of the guides and means for fixing the position of the jaws, made in the form of grooves mounted in the housing, spring-loaded media, whose axes are perpendicular the axis of the rod, balls mounted on the ends of the pistons, with the possibility of interaction with the grooves, and nuts to adjust the magnitude of the force that the balls exert on the grooves.
