Flexible forming device for processing three-dimensional workpieces using bendable rollers

technical field

A flexible forming device for processing a three-dimensional workpiece by using a bendable roller is a device used for plastic forming of the workpiece and belongs to the field of mechanical processing.

Background technique

At present, the processing of cylindrical or rod-shaped three-dimensional workpieces is mainly through traditional processes such as spinning, roll forging, and cross wedge rolling, which not only cost high, but also take a long time. Therefore, it is necessary to provide a device to solve the processing of the workpiece and greatly improve the production efficiency and the like.

Contents of the invention

The purpose of the utility model is to change the traditional processing method of cylindrical or rod-shaped three-dimensional workpieces, and provide a flexible forming device using bendable work rolls.

The above-mentioned purpose of the utility model is achieved in that, in conjunction with accompanying drawing, description is as follows:

A flexible forming device for processing three-dimensional workpieces using bendable rolls, including work rolls, an adjustment mechanism, a frame, and a work roll drive mechanism. At least one of the work rolls is a bendable and adjustable flexible work roll. There are several adjustment mechanisms that can adjust the degree of curvature of the work rolls.

The bendable roller can be composed of two, one is arranged on the outside of the cylindrical workpiece, and the other is arranged on the inside.

The working rolls arranged inside are passive bending rolls or simple elastic rolls that do not need to be adjusted. The simple work roll can be designed as a rigid core work roll with an elastic sleeve to make the inner work roll and simplify the structure of the inner work roll.

The bending work rolls can also be composed of two or more, and they are all uniformly distributed along the inner side of the workpiece circumference or evenly distributed along the outer side of the workpiece circumference.

The frame is designed as a double support type or a cantilever type.

A part of the double-supported frame is designed to be detachable. After the detachable part is removed, one or more work rolls can be lifted to put in or take out workpieces.

The utility model draws lessons from the multi-point forming technology, and uses bendable rollers instead of the traditional processing method to process cylindrical or rod-shaped workpieces with a certain three-dimensional shape. Compared with the traditional technology, this technology has low manufacturing cost and short cycle of forming parts , save a lot of manpower and material resources, and greatly improve production efficiency.
