Problems solved by technology

Using welding forming, the temperature of each part of the workpiece to be welded is uneven due to local heating. After cooling, due to the difference in thermal expansion and contraction and plastic deformation, internal stress and deformation will occur in the welded structure, and there may be cracks, pores, slag inclusions, Defects such as incomplete penetrati...

Abstract

The invention provides an inner bore double-face boss combined extrusion molding die and molding method. The die comprises a male die component, a female die component and a guide component; the male die component comprises a top plate and a male die, the top of the male die is connected to the center of the bottom of the top plate, the female die component comprises a base, a female die, a central shaft and a back pushing device, the female die is matched and located with a central groove of the base, the central shaft is vertically arranged in the center of the base, the center of the female die is provided with a first location hole, the center of the male die is provided with a second location hole, the top of the central shaft penetrates through the first location hole to be inserted into the second location hole, the back pushing device comprises a plurality of back pushing rods and a back pushing disc, the plurality of back pushing rods are uniformly arranged on the back pushing disc along the peripheral direction at intervals, the tops of the back pushing rods penetrate through the base and a through hole in the female die in sequence and can slide along the through hole, two ends of the guide component are respectively connected to the bottom of the top plate and the top of the base, and the top plate can move along the guide component. The inner bore double-face boss combined extrusion molding die is concise in technological process, high in production efficiency and high in use rate of raw materials, and the surface quality of molded parts is good.

Example Embodiment

[0024] Embodiment one:
[0025] For an outer diameter D 1 40mm, inner diameter D 3 For a billet with a thickness of 15mm and a thickness t of 6mm, it is necessary to form a double-sided boss in the inner hole, and the outer diameter of the boss is D 2 20mm, the inner diameter of the boss and the inner diameter of the blank D 3 Equal to 15mm, height H is 8mm.
[0026] According to the principle of constant volume, the volume reduced in the direction of the thickness of the blank is equal to the sum of the volumes of the bosses: Extrusion stroke h=2H(D 2 2 -D 3 2 )/(D 1 2 -D 3 2 ), according to the formula, the extrusion stroke h can be calculated as 2mm.
