Feeding device for rotary swaging forming

Abstract

The invention provides a feeding device for rotary swaging forming. The feeding device is mainly composed of a base, a motor, an adjusting mechanism, a clamping mechanism, a transmission mechanism and a tensioning mechanism. The relative position of the clamping mechanism is symmetrically adjusted through the adjusting mechanism, so that the clamping center of the clamping mechanism is not changed; when the adjusting mechanism adjusts the position of the clamping mechanism through the tensioning mechanism, a chain or a belt in the transmission mechanism can still be in a tensioning state; and rotation of the clamping mechanism is achieved through the transmission mechanism, and continuous feeding is achieved through the clamping force of the clamping mechanism. The feeding device for rotary swaging forming provided by the invention is simple in structure and convenient to control, the problem that the reverse flow of materials is larger than the forward flow in the rotary swaging process can be solved, and the axis height of bars or pipes with different diameters can be the same as the center of a rotary swaging die when the bars or the pipes are fed. The feeding device is arranged at the outlet position of a rotary swaging machine, and the material guiding function of the bars or pipes with different diameters can be achieved.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to a swaging forming feeding device. Background technique [0002] Rotary forging is a progressive forming method that uses high-speed rotation of the forging die and applies high-frequency forging force to blanks such as bars or pipes to reduce the cross-sectional size or change the shape of the blank. It is a metal forming process with discontinuous step-by-step forming and uniform deformation. [0003] Rotary forging can process a large number of different shapes and inner cavities, and has near-net shape, high material utilization rate, continuous fiber streamline, and can increase the strength of parts through work hardening. At present, rotary forging generally uses a mechanical system and a hydraulic system to clamp and feed materials at a constant speed. During the downward process of the forging die, the blank is continuously fed in the axial direction. W...
