Abstract

The invention relates to the processing of metals by pressure and can be used for the bulk forming of articles by the method of rolling. The purpose of the invention is the expansion of technological capabilities by providing precipitation of rods with 12 ratios, a decrease in metal intensity and an increase in productivity. The device contains a punch (П) 17, connected with a spherical moving mechanism, and an axially movable matrix (M) 1. A holder 12 is rigidly fixed around P 17, into which several pushers 15 are movably mounted in contact with M 1, which are movably connected to a sub-stamping plate 11 with several guide columns 3 and bushings 4. The blank 8 is installed in M 1. The swinging R 17 moves in the axial direction and deforms the workpiece 8. The finished product is pushed out by the pusher 9. Thanks to the holder 12 with its pushers 1 5 presses M 1, the latter moves ahead with respect to P 17, which makes possible the free advance of M 1 until the end of the cycle. 1 il.

Description

The invention relates to the processing of metals by pressure, in particular to devices for sphere-moving punching.

The purpose of the invention is the expansion of technological capabilities by providing precipitation of rods with a ratio, reducing the metal intensity of the device and increasing productivity in the manufacture of parts.

The drawing shows the structure of the device.

The matrix 1 is movably connected to the bottom plate 2 through the direction of the column 3 and bushings 4. In the matrix space there is a spring 5. The lugs 6 of the closed height of the matrix 1 are located on the bottom plate 2. Restrictive levers 7 are fixed on the plate 2 and are movably connected with the matrix 1. The workpiece 8 is installed in the working area of the matrix 1 on the pusher 9, rigidly connected to the ejector 10. The pusher 9 rests with its base on the plate 11. The holder 12 is rigidly fixed to the movable tool holder 13 and consists of the upper and lower clips. The balls 14 are mounted in the channel a of the holder 12 and interact with the pushers 15 in contact with the matrix 1. The springs 16 are mounted under the pushers 15. The punch 17 is fixed on the tool holder 13 by the holder 12.

Device for sphodynamic stamping works as follows.

The blank 8, in the initial position representing the rod c, is placed in the matrix 1, which is in the upper position. The holder 12 together with the oscillating punch 17 moves in the axial

the direction along with the press slider (not shown) to the workpiece 8. The pushers 15 with some advance in relation to the punch 17 press on the matrix 1 and

continuously pushing her. The punch 17 deforms the preform until it is completely formed. The stops 6 are interchangeable and are set upon adjustment. Ejection of the finished product is performed by the pusher 9

Q and ejector 10. Restrictive levers 7 hold the matrix 1 at the time of ejection of the workpiece 8.

Claims (1)

Invention Formula 5 A device for a sphere-moving punching comprising a punch fixed with a tool holder on a tool holder and associated with a spherical moving mechanism, a matrix mounted coaxially with the punch on a press base plate, capable of being moved in the axial direction, characterized in that in order to expand technological possibilities ensure the precipitation of rods with a ratio, decrease the metal consumption of the device, increase productivity in the manufacture of parts, the holder is made in the form of connected and located coaxially with the punch of the upper and lower holders, at the ends of which, facing one another, are annular grooves and channels connected to the lower groove of the channels located symmetrically to the axis of the ferrule, and the device is equipped with balls located in the grooves and channels and spring-loaded pushers mi installed in the channels. 0 0
