SU914321A1 - Apparatus for producing bars having voids from moulded composition - Google Patents

Description

The invention relates to a device for the production of materials and products from wood press mass by pressing.

There are known devices for the manufacture of bars with voids from wooden press masses, including a loading mechanism, heating elements, a channel with an expanded part on the loading side, and a working body with hollow-forming elements in the form of rotating shaft bearings with screw thread C] I [23.

These devices make it possible to obtain linear products of the type of bars with voids only along the closed contour of the channel section, i.e. products of a limited range. Products of such a section as channels, angles cannot be obtained directly at the exit of the product from the channel.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that dividing ribs are made on the channel surface along its vertical axis.

FIG. 1 shows the device, a general view in section; in fig. 2 is a channel section with two separation ribs, section A-A in FIG. one; in fig. 3 ~ channel cross-section with four separation ribs, section A-A in FIG. one.

The device includes a housing with a tapering faceted channel 1 having a loading zone, a molding zone and a heating zone, a working body in the form of a screw-core-2, a receiving funnel 3, removable separating ribs 4, heating elements 5.

The device works as follows.

During the rotation of the screw-puncher 2 wood press mass supplied from the receiving funnel to the loading zone, moves along the channel

1 in the direction of the heating zone, this results in its compaction and the polymerization of the innermost one. Separating removable ribs 4, the height of the cross section which provides a gap with screw clamping machine 2, are part of the forming surface of the housing.

Due to the presence of ribs and the minimum gap (1 + 0.5 mm) between the ribs and screw bushing 2, the output of the channel can be easily divided into two or more (depending on the number of ribs) parts along the longitudinal axis. At the same time receive constructional material of a various profile - a channel, a corner and t. d.

Claims (1)

Claim Device for the manufacture of bars with voids from the press masses, mainly wood, including the loading mechanism, heating elements, the channel with the expanded part on the loading side and the working body 5 with holders in the form of a rotating shaft in bearings with a screw thread, which is excellent, because, in order to increase productivity, on the surface The canal along the vertical axis contains separation edges.
