Small and medium-sized ring horse frame reaming rotation control device and its application method

Abstract

The invention relates to a small and medium-sized ring part mandrel supporter hole-expanding rotary control device and a using method thereof. The small and medium-sized ring part mandrel supporter hole-expanding rotary control device comprises a mandrel supporter, a mandrel which is rotatably and detachably arranged on the mandrel supporter and is used for allowing a ring part to pass through, amandrel drive part for driving the mandrel to rotate, and two groups of wrapping roller assemblies which are symmetrically arranged at the two sides of the mandrel; each wrapping roller assembly comprises a lever which swings towards the mandrel, a wrapping roller which can be rotatably arranged at one end of the lever for pressing the ring part, a wrapping roller drive part for driving the wrapping roller to rotate, and a lever drive part which is connected with the other end of the lever for driving the wrapping roller to swing; the mandrel and the wrapping rollers are horizontal and are parallel to each other; and the mandrel drive part adopts a manual mode or an electric mode; and the wrapping roller drive parts drive the mandrel drive parts to drive or independently drive. The small and medium-sized ring part mandrel supporter hole-expanding rotary control device is stable in working condition, is controllable in rotation angle of the ring part, and is stable in forming process; and the formed ring part is high in dimension precision.

Description

technical field [0001] The invention belongs to the technical field of forging, and in particular relates to a small and medium-sized ring saddle reaming rotation control device and a use method thereof. Background technique [0002] In the field of forging technology, the forging process of reducing the wall thickness of the hollow blank and increasing its inner and outer diameters is called hole reaming. There are two methods of hole reaming: ring rolling and horse frame reaming. Horse frame reaming is to insert the mandrel into the circular blank with holes, place the two ends of the mandrel on the horse frame, and realize the hole reaming by applying pressure to the outer diameter of the disc with holes and the continuous operation of the mandrel. It is widely used for ring reaming in small batches and to provide blanks for large ring rolling. [0003] Most of the existing horse frame hole reaming process is carried out by workers who control the rotation of the mandrel...

AI Technical Summary

Problems solved by technology

This manual control method cannot guarantee the consistency of the rotation angle of the ring, and the degree of automation is low. It is prone to problems such as out-of-round and uneven wall thickness of the forged ring, which greatly affects the consistency of the quality and performance of the ring product.
