Manufacture of multiple pipes resource technology PP167
PURPOSE AND SCOPE
The development is intended for metallurgical industry for obtaining sleeves molds used in continuous casting billets machines. They are in the form of a square tube with a cylindrical ending. Products for other industries can be obtained using this method.
Marketing research has shown that the liner molds were manufactured by this technology. They meet all requirements and are competitive in the markets of Ukraine, and industrialized West and CIS countries. Practical recommendations based on the received technologies are used in PJSC "Kryukivsky carriage works plant ", PJSC HK" AvtoKrAZ ", in the joint - stock company SPE "Transmash", scientific - production enterprise "Tangsten".
INTELLECTUAL PROPERTY STATUS
4 patents of Ukraine were obtained for the utility model.
THE IDEA OF THE DEVELOPMENT
The development is a technological process manufacturing of cartridges and multifaceted cartridges pipes of copper and its alloys. The essence of the development lies in the method of receiving by pulse influence of energy of explosives on form change of initial workpiece. This made it possible to get uniform deformation and eliminated availability of different walls thicknesses in the part after punching. The technological scheme and technological equipment were tested during stamping cartridges crystallizers with a continuously expanded copper tube with a wall thickness of 16 mm in production conditions.
The important indicators of the process are the possibility stamping blanks without additional costs and special conditions, as well as no need in stamping equipment.
THE DEVELOPMENT READINESS STATUS
Industrial designs, technological equipment, computer math process model were made. The optimal setup parameters for receiving crystallizer casings were installed.
