(54) SEDOV DEVICE FOR MANUFACTURING PRODUCTS FROM POLYMERIC MATERIAL

I

The invention is refractory to the machining of polymeric materials and can be used in the manufacture of rubber balls.

A device for treating spherical surfaces is known, which contains a support for setting the workpiece and holders with cutters located on both sides of it.

The known device is intended for the processing of metal products with cutters, which are made in it in the form of tubes l.

The disadvantage of the device is that it cannot process elastic porous material.

Closest to the present invention is a device for the manufacture of products made of polymeric material, including two drive coaxially arranged spindles mounted on the frame that can be moved with fixed cutters on the ends facing each other and mounted between the spindles of the workpiece 2.

Odaako the device does not provide the possibility of obtaining spherical products.

The purpose of the invention is to provide the possibility of obtaining articles of spherical shape from an elastic porous material.

This is achieved by the fact that in the device for the manufacture of polymeric products

10 of the material, including ssimatirovanny on, the frame with the possibility of moving two drive coaxially arranged spindles with cutters attached to the ends of the other to the other ends and installed

IS between the spindles holder, for the workpiece, each cutter is made in the form of a plate with a semicircle concave in an arc. cutting edge and located on both its lateral sides of the limit of displacement of the installed product.

Claims (2)

 Each displacement limiter of the cut product is made in the form of arcuate plates. On fvg. 1 shows the proposed arrangement, a general view; in fig. 2 - cutter; in fig. 3 is a view A of FIG. 2; FIG. 4 view 6 in FIG. 2. The machine consists of a bed 1, two platforms 2 that are sliding along the page 1 of 1 with 3 spindles 4 driven from electric motors 1 on them, at the ends of which there are fixed incisors 5, made in the form of plates with sharp incisors cutting along the semicircle by edges. Each rezed 5 has two arcuatepieces of flap 6, which are limiting the mixing from the axis of rotation of the cutters of the cut ball. To prevent the accumulation of sawdust, flaps 6 and cutters 5 do not touch each other. Between the movable platforms 2 on the bed 1 there is fixed a holder for the workpiece, made in the form of a plate 7, so that the sheet blank 8, not less than the diameter of the manufactured balls, attached to the left side of it is equal to the distance from the cutters 5. Movable platforms 2 is driven by two snarls. gami 9, taut yu, pedal 11 and return spring 12 by means of a bar 13 with a slot fixed to the frame 1. The stroke for approaching the platform 2 is adjusted by setting the stop. The device works as follows. The electric motors 3 are turned on for regular operation, and the cutting edges of the cutters 5 describe hemispheres. The blank 8 of a pofisty elastic material (for example, from polyurethane foam) is placed on the right side of the opsf plate 7, the pedal 11 is pressed downwards, the moving platforms and the rotating cutters 5 coaxially approach each other, cutting the material at a cutting angle 9O until the ball is completely cut from the blank. After this, the pedal 11 is released, the spring 12 returns to its original position all moving parts and the cutters 5 are consumed. The workpiece 8 is moved to a new place for a new ball. Thus, the proposed device allows to produce balls of elastic porous material, such as polyurethane foam. The formula of the invention and 1. The device (for the manufacture of products from polymeric material, including two drive coaxially arranged spindles with fixed on the frame with the possibility of movement with fixed on the ends of the cutters fastened to each other and the holder for the workpiece between each spindle And often, with a chain of enabling spherical-shaped products to be made of an elastic porous material, each cutter is made in the form of a plate with a semicircle of the cutting edge bent in an arc and 2. The device of claim 1, which is the fact that each cut-out of each cutout (the product is made in the form of arc-phase shields.
