Abstract

The invention discloses an opposite roller spinning device for forming tube-shaped pieces of different diameters and wall thicknesses, and relates to opposite roller spinning devices. The opposite roller spinning device aims to solve the problems that existing mold spinning equipment is high in mold cost, poor in universality and long in manufacturing cycle. According to the opposite roller spinning device for forming the tube-shaped pieces of different diameters and wall thicknesses, a rack is installed on a base, and a gear case is installed on the base; a spindle motor is connected with the input end of the gear case, and an eight-claw chuck is installed at the output end of the gear case; two lifting assemblies are installed at the two sides of the rack correspondingly; two screw nut connecting bases are installed on screw rods of one lifting assembly separately; one side of each screw nut connecting base is connected with a main sliding frame, and the other side of each screw nut connecting base is installed at one side of the rack in a sliding mode; the two main sliding frames are connected through an upper cross beam; and an inner rotation assembly penetrates through the upper cross beam to extend downwards to the position between the two main sliding frames, and an outer rotation assembly is installed between the two main sliding frames. The opposite roller spinning device is used for spinning thin-walled tube-shaped pieces.

Description

technical field [0001] The invention relates to a counter-wheel spinning device, in particular to a counter-wheel spinning device for forming cylindrical parts with different diameters and wall thicknesses. Background technique [0002] Wheel spinning is a kind of powerful spinning technology, which is developed on the basis of traditional spinning with mandrel. It uses a pair or several pairs of inner and outer rotary wheels to perform plastic processing on the inner and outer surfaces of the workpiece at the same time. Since there is no mandrel and the number and shape of the wheel pairs can be adjusted according to the actual situation, the wheel spinning has the following advantages: by adjusting the radial distance of the wheel pairs, pipe fittings with any diameter and different thickness within a certain range can be processed, thus reducing The production cost of the mandrel is reduced; in the case of the same initial wall thickness and deformation degree, compared ...
