Abstract

The invention relates to the processing of metals by pressure and can be used in the blank production of machine-building enterprises for the separation of rolled metal. The purpose of the invention is to simplify the design of the device for the separation of rolled metal and to improve the quality of the resulting blanks. The device contains knives 1 and 4 installed in the holes of the disks 2 and 5. The disks are installed with the possibility of rotation around the axes located on both sides of the rental axis. A spring-loaded pusher 8 is installed in the hole for positioning the cut-off part, interacting with the first ball 12 of those placed in a curved channel with a non-working end. The last of the balls 12 interacts with the wedge 14, which covers the turning disk. The working surface of the wedge 14 is located from the center at a distance, gradually decreasing in the course of turning the disk by an amount equal to the course of the ejector. 2 hp f-ly, 1 ill.

Description

but

The invention relates to the processing of metals by pressure and can be used in the blank production of machine-building enterprises for the separation of rolled metal.

The purpose of the invention is to simplify the design of the device for the separation of rolled metal and to improve the quality of the resulting blanks.

The drawing shows a general view of a device for separating rolled products.

The device for separating the rental contains a sleeve knife 1 mounted in the disk 2 in its opening located along the chord for placing the rental 3 ". The blade 4 is set to. the disk 5, in its opening b, also located along the chord, for accommodating the cut-off workpiece 7; In the aperture 6 of the disk 5, the pusher 8 is placed with a spring 9 designed to create an axial compression force in the cut workpiece. The pusher 8 with the working end 10 interacts with the cut end of the workpiece 7, and the non-working end 11 with the balls 12 placed in the hole 13. The balls 12 interact with the wedge 14, the working surface 15 of which is located from the center of rotation of the disk 5 at a distance decreasing the direction of rotation of the disc, by an amount equal to the course of the pusher 8 to create

axial compression force. To transfer the force from the knife 4 to the knife 1 and change the direction of rotation of the discs, a lever 16 with a spring 17 is inserted,

A device for separating the rental works as follows.

The rental 3 is placed in the holes of the sleeve knives 1 and 4 up to the stop with the working end 10 of the pusher 8, the disk 5 is rotated with a lever (not shown). When the blade 5 with the knife 4 is rotated by the lever 16, the knife 1 moves in the opposite direction, as a result of which the knives 1 and 4 cut the rolled metal.

When cutting the rolled stock due to the eccentric arrangement of the axes of the sleeve knives 1 and 4 relative to the axes of rotation of the disks 2 and 5, the frontal part of the knives as the rolled 3 is shifted

dit from its surfaces obtained in the separation process.

When the disk 5 is rotated, the outermost hinge interacts with the surface of the wedge, whereby the force is transmitted to the pusher 8, which axially compresses the cut piece. Upon further movement, the cut billet is removed from the knife by the pusher 8. The spring 9 returns the pusher 8 to its original position, and at the same time the lever 16 returns the discs to the initial position by means of the spring 17. After that, the cycle repeats.

Claims (2)

Invention Formula t 1, A device for dividing the rental, containing a base, knives, kinematically connected to each other, mounted on the base and made with holes to accommodate the section being cut, located in the initial position on the axis of the supply of rolled metal, and the axial compression mechanism of the cut billet in the form of in one of the knives, the pusher and the means for moving it in the form. A wedge, characterized in that, in order to simplify the construction and improve the quality of the workpieces produced, the knives are made in the form of rotary disks mounted on axes in one plane, and the holes in them to accommodate the rolled steel are located along a chord in a plane perpendicular to the axis m discs, while the axis of rotation of the disks are offset along the axis of the supply of rolled on different sides of it, 2. The device according to claim 1, characterized in that the means for moving the pusher of the axial compression mechanism of the cut-off workpiece is provided with rolling bodies in the form of balls located in the knife hole between the pusher and the working surface of the wedge, 3, the Device in PP. 1 and 2, T is characterized in that the working surface of the wedge is formed by a curvilinear generatrix, while the distance from the axis of rotation of the disk to the working surface of the wedge is made decreasing in the direction of its rotation.
