A large-diameter thin-wall back-sealing structure counter-wheel spinning device based on edge constraints

Abstract

The invention discloses a large-diameter thin-wall sealing structure opposite roller spinning device based on edge constraint. The problems that existing die spinning equipment is high die cost, poorin universality and long in manufacturing period are solved. The large-diameter thin-wall opposite roller spinning device adopts a horizontal structure, transverse slide seats of an inner spinning roller mechanism and an outer spinning roller mechanism are installed on guide rails, and the displacement of the transverse slide seats is adjusted by two independently-controlled hydraulic cylinders; longitudinal guide rails of the inner spinning roller mechanism and the outer spinning roller mechanism are installed on the transverse slide seats correspondingly, longitudinal slide seats are connected with the longitudinal guide rails and controlled by the independent hydraulic cylinders, and accordingly, it is achieved that spinning rollers do compound motion in a plane; and the angle of the inner spinning roller and the angle of the outer spinning roller are controlled by a gear and a rack. A spinning machine seat is provided with a fixing groove, and the fixing groove is used for installing a rotary disc fixing seat; the rotary disc fixing seat is provided with a round opening which is used for installing a blank fixing rotary disc, and a blank is fixed to the blank fixing rotary discthrough a bolt; and a gear box and a motor are installed in the position, on one side of the rotary disc fixing set, of the spinning machine seat. The large-diameter thin-wall sealing structure opposite roller spinning device based on edge constraint is used for spinning forming of large-size sealing components.

Description

technical field [0001] The invention relates to the technical field of wheel spinning devices, in particular to a wheel spinning device with a large-diameter thin-walled back cover structure based on edge constraints. Background technique [0002] The spinning forming process has unique advantages in the forming of thin-walled bottom cover structures compared with welding and deep drawing due to its advantages of simple mold, flexible process, and wide adaptability. It is currently widely used in conical covers, spherical heads, curved busbar components, etc. Manufacture of products. Most of the traditional spinning forming processes require spinning mandrels, but when the structure size of the back cover is large, the mandrelless spinning process is widely used due to its low cost and short manufacturing cycle, such as the large head parts in the petrochemical industry A large number of coreless one-step and two-step spinning methods are used. However, the current head sp...
