THE PROCESS OF MANUFACTURE OF BIMETALLIC TUBE
ELEMENTS FROM DIFFERENT METALS BY DRAWING
WITH THINNING
Introduction. Modern trends in the development of the engineering industry are
characterized by increased requirements for the quality and performance of products
while reducing the cost of their production. To ensure the effectiveness of engineering
products in their designs are widely used various metals and alloys with high relative
strength, as well as specific functional properties.
Bimetallic tubular elements (BTE) are used in the construction of high-tech
engineering products for connecting pipelines of various metals such as aluminum,
steel, titanium and others.
Methods of production of BTE are introduced in metallurgical and machine-
building production and based on methods of molding and plastic deformation. They
are focused on mass and large-scale production. They are economically advantageous
to use in small-scale and single production. Methods based on high-energy processes
of plastic deformation and diffusion welding, which can be implemented in small-scale
production, require specific conditions of implementation and increased safety
requirements.
The sharp competition of mechanical engineering products in the world market
requires the mobility of production, and discrete unstable programs of production of
products-production of their single copies. The mobility of production can be provided
by using the universal equipment of machine-building enterprises, as well as by
creating technologies for the manufacture of bimetallic tubular elements from
traditional semi-finished products, such as sheet semi-finished metals and alloys, using
non-complex die tooling methods of drawing.
The aim of the work is to develop a method of control of the main parameters of
working out the technological process of pulling with the refinement of dissimilar sheet
