Description

The proposal relates to the field of laser processing of materials and can be used in the manufacture of bulk products from dissimilar materials, in which different sections had different properties.

These products include heat exchangers designed to operate in aggressive environments in which the outer part should be made of stainless steel and the inner part should be made of a material with high thermal conductivity, for example, copper.

They also include a tool that works in boreholes, the outer surface of which must be abrasion resistant, and so on.

A device for manufacturing a volumetric product in the form of an outer shell with a bottom, containing a container open on top, in which the supporting device for the manufactured volumetric product, a support device drive, metering devices and drive devices, respectively, layer-by-layer laser sintering and removal of excess powder, are placed vertically; [one]

This device requires a lot of time for the manufacture of products and therefore are not effective enough.

The result, to achieve which this technical solution is directed, is to reduce the time and reduce the cost of creating products.

This result is achieved due to the fact that the device for manufacturing a three-dimensional product in the form of an outer shell with a bottom, containing a container open on top, in which the supporting device for the manufactured three-dimensional product, a support of the supporting device, metering devices and drive devices, respectively laser 2

sintering and removal of excess powder, equipped with a set number of layers in the group of layers for manufacturing the outer shell, devices for filling the inner cavity of the obtained shell with powder material, removing excess powder from the inner cavity of the shell and laser sintering of the powder material in the inner cavity of the shell and a switching unit for layer-by-layer laser sintering , and is configured to control the drives of the support device, the layer-by-layer laser sintering device and the removal device excess powder by means of a programmer connected to a setter of the number of layers in the group of layers for the manufacture of the outer shell

An example of the implementation of the inventive device is illustrated by drawings, where in FIG. 1 shows the inventive device, FIG. 2 - place A, in FIG. 3 is a diagram of a device drive.

A device for the manufacture of bulk products with an outer shell is made in the form of a container 1 open on top, in which a supporting device 2 for manufacturing bulk products 3 with a drive 4 is placed with the possibility of vertical movement relative to the latter and placed above the working plane 5 defined by the upper edges of the container 1 devices 6, 7 respectively planarization of the powder layer and layer-by-layer laser sintering with drives 8, 9.

The device has a metering device 10 and 11 for planarization (alignment) of the powder layer and filling the inner cavity 12 with a working material, as well as devices for removing excess powder 13, 14 from the surface of the layers and from the inner cavity of the shell 12 with the corresponding drives 15-18.

To control the drives when creating the shell, the drive control programmer 19 and the setter 20 of the number of layers of the group L of the outer shell are used. In addition, the device is equipped with an additional device 21 with a block switching energy modes for laser sintering of the material of the inner cavity of the shell with the drive 22.

3

First create on the supporting device 2 the bottom part 23 of the product.

Then create the outer shell 24 by layer-by-layer filling, planarization and programmable selective sintering of a given area in the plane of each sintering layer, followed by removal of excess powder.

The shell is created by groups of layers, and after creating each of the groups of layers, the internal cavity 23 of the shell 22 is filled to the height of the group L with material, followed by thermal exposure to the laser beam to its entire depth.

For the manufacture of the outer shell and the inner cavity of the shell, materials of varying composition may be used.

The outer shell and the inner cavity of the shell are formed in various energy modes.

Thus, this technical solution will allow:

- reduce the time of creation of products;

- reduce the cost of creating products.
