Abstract

The invention is used to eject articles from double-impact cold stamping dies. The aim of the invention is to simplify the construction of the ejection mechanism. The mechanism contains two double-arm levers 9 and 10 placed in slider 6 on axles 7 and 8 and a spring (in springs 11). Push the product out of the punches with the workpiece 12, which enters the punch 3 or 4, at the landing position. Preparation 12 acts through the ejector to the inner end of the double-shouldered levers. Having pivoted on the axis of the lever, the outer ends through the ejector 1 or 2 eject the product. 1 Il. & (L X CO 00 00 ff

Description

1n

The invention relates to the processing of metals by pressure and can be used in double-impact cold forming machines for ejection of articles from the mat.

The purpose of the invention is to simplify the design of the ejection mechanism.

The drawing shows the pushing mechanism, a general view,

The mechanism consists of ejector 1 and 2, placed in the matrices 3 and 4 of the punch head 5. In the slider 6 on the axes 7 and 8 there are two levers 9 and 10, spring-loaded with springs 11.

The mechanism works as follows.

In the position indicated in the drawing, the matrix 3 is in the landing position. The workpiece 12, stamped by the upsetting tool along the machine cycle, moves (to the right) with a punch head 5. Matrix 4 is installed on the discharge line. Double shoulders lever 9, turning on axis 8 under the action of spring 11, rests with its internal end on ejector 2 of matrix 4 Coming on the landing line to the matrix 4 a new billet is acting through the ejector 2 on the double-arm lever 9 Lever 9, turning on axis 8 towards Compiler N.Timofeeva Editor N.Shvyschka Tehred A.Kravchuk Proofreader G.Reshetnik

with a shoulder, ejects the stamped product from the matrix 3 with the ejector 1. The new billet is planted in the matrix 5, moves (to the left) to the line by ejecting, the cycle is repeated using the double-arm 9.

The proposed ejection mechanism is simple to manufacture and operate.
