Description

Ieobretenpe belongs to the field of manufacture of thermal insulation products, of course, shells, segments.

A device for the manufacture of products is known, comprising a pressing chamber,

connected to the mouthpiece, the bunker and then., Shen with dornok and drive C.

The closest technical solution to the invention is a device for preparing heat (soldering products, including a pressing chamber with a mouthpiece and a loading opening, a hopper, a piston with a soiiii mandrel, and a drive I. However, in known devices, the molding mass coming from the hopper into the pressing the chamber is unevenly distributed over its cross section, in connection with which a heterogeneous structure is obtained in the molded article.

The aim of the invention is to ensure the homogeneity of the structure of the molded article.

For this purpose, in a device for the manufacture of heat-emitting products, including a pressing chamber with a mouthpiece and a discharge opening, a bunker, a hollow with a hollow road and an actuator, the working surface of the piston is bevelled at an angle of repose of the molding material, and the lower surface, and the hollow mandrel is equipped with slitting knives and a heater.

In addition, the device can be equipped with a cylinder made with a diameter greater than the diameter of the mouthpiece.

The drawing shows the proposed device.

The device includes a press chamber 1, filled out in the form of a hollow cylinder, with unit 2, mounted on frame 3, a bunker 4, a frontal surface embedded in the side surface of the pressing chamber 1, a hollow piston 5 having an obliquely angled mass of an insulating mass through which eoosno passes a built-in heater 6 at the site for molding the product an end mandrel 7 attached at one end to the frame 3, and at the other end attached and simultaneously centered in the mouthpiece 2 with the help of knives 8 longitudinal th

cutting, cutting the edge of which is iodine angle 15-45 to the axis; Amy cylinder 9, air diameter, which is 10-30 mm larger than the internal mouthpiece eTpa t2. The iliac knife 1O is located in the plane of the gap between the mouth: ear 2 and njfflf / iHbiM cylinder 9 and is driven by two pneumatic cylinders

The piston 5 is connected to the drive, obvgp & belive its return -e-yogupalitelny dvvzhenie.

The device works in a dim way. Through the hopper 4, the mold 17U mass is fed into the pressing chamber 1, where, due to the beveled frontal surface of the piston 5, it is evenly distributed over the cross section, a drive is inserted, causing the pores 5 to move, which pushes the molding material along the pressing chamber, where it is pressed and thanks to mandrel 7, a cylindrical shape is acquired. Heating the mandrel 7 by not molding the product with the use of the built-in heater 6 provides a smooth inner surface of the product.

With the long-term advancement of the molding material due to pushing its new porous fibers, it enters mouthpiece 2, where cutting in the longitudinal direction with the slider of longitudinal cutting knives 8, the location of the edges of the knife edges under the ANGLE to the axis of the mandrel provides: Another incision into the mass eliminates the violation and integrity of the product. Then the mass enters the secondary shshindr 9, which prevents the curvature of the mass when it leaves the Mouthpiece 2, where it accumulates until the required length of the shell is reached.

After that, the pneumatic cylinders 11 and, accordingly, the guillotine knife 10, which performs cross-cutting of the mass in one and in the opposite direction, are actuated due to shortening (- time for cross-cutting. The finished shells or segments are pushed out afterwards). porcg mi molding mass.
