(57) Abstract:The invention relates to the processing of metals by pressure and can be used to produce containers round shape by rolling. Rolls contain console installed in the rack welded frame rolls. Rolls made in the form of a drive, the clamping and deflecting. The drive roller associated with an electric drive, installed on a welded frame. The presser roll is made with the capability of raising and lowering for the installation of steel sheet. Reduced labor intensity of production capacity round shape of a steel sheet with a diameter of 200 mm and a length of 400 mm Rolls console belong to the field of mechanics and mechanical engineering companies and are intended for the manufacture of containers made of sheet steel with a diameter of 200 mm and a length of 400 mmFamous rolls console containing a console installed in the rack rolls. The device is intended for the production of cold-formed profiles of rental (patent RU 2096112 C1, B 21 D 7/02, 20.11.1997).The technical challenge is to reduce the complexity in the manufacture of containers of circular shape with a diameter of 200 mm and a length of 400 mm sheet steel.The inventive cantilever rollers is driven, clamping and deflecting rolls, cantilever rack frame, is rolling the sheet to obtain the capacity of a round shape. The drive roller rotates from the drive that is installed on the frame. The presser roll is made with flats. Using the flats on console rolls conveniently to remove the tank.Rolls console structurally consist of a welded frame made of steel sheet. Rolls drive, clamping and deflecting cantilever mounted in the rack frame. The presser roll is made with flats. The actuator is mounted on the frame and connected with a drive roller. The presser roller is connected with a drive roller through the open gear.Rolls console are as follows. Steel sheet is inserted between the drive and pressure rollers through the flats on prijemnom felling and at an angle to the horizontal. Include motor, drive rolls and the retainer are rotated and steel sheet starts to move. Using the deflection of the roll sheet is rolled to obtain capacity round shape. After rolling, if the flats of the pressure roll is in the down position, turn off the motor and remove the rolled container with the pressure roll. News round shape with a diameter of 200 mm and a length of 400 mm sheet steel they are equipped with a welded frame under the rack, and the rolls are made in the form of a drive associated with the actuator mounted on the frame, the clamping performed with the capability of raising and lowering to install and pressing the steel sheet, and deflecting for rolling the steel sheet to obtain the capacity of a round shape.
FIELD: mining industry, particularly for oil and gas extraction from underground formation, namely to join drill pipe sections with the use of strut included in threaded pipe connection.
SUBSTANCE: metal item forming method involves mechanical deforming metal strip, for instance slotted strut formed of alloy selected from group containing Cu/Be, Cu/Sn, Cu/Ni, Cu/Ni/Sn, Cu/Zn, Cu/Si, Ni/Cr, Cu/Al, Al/Ti, Al/Mg, Al/Zn to obtain formed blank including hollow section made as truncated cone without helical slot; mechanical deforming conical section to form helical slit in it.
EFFECT: prevention of plastic threaded connection deformation, increased reliability of drill pipe connection, simplified strut production technology.
