Multifunctional ring rolling machine

Abstract

The invention relates to a multifunctional ring rolling machine, which has the structure that: two small rolling wheel parts with the same structure are radially arranged at the two sides of a core roller of a common vertical type ring rolling machine, and dragged to move on a certain track along the radial direction of a workpiece by an oil cylinder, the position of the small rolling wheel partscan be locked by a hydraulic valve, the equipment adjustment is simple, convenient and fast, and the position of a push wheel can be adjusted without stopping the machine, therefore, the ring rollingmachine is applicable to manufacturing ring pieces with different extend-rolling ratios and complex shapes, combines the basic functions of the common ring rolling machine and a multi-point radial rolling machine, expands the application range of the ring rolling machine and improves the efficiency of the ring rolling machine.

Description

1. Technical field: [0001] The multifunctional ring rolling machine of the present invention relates to a rotary forging equipment, which is the development of the ordinary ring rolling machine (also known as the hole reaming machine), and can be used to compare the rolling expansion ratio (the inner diameter of the workpiece after rolling to the inner diameter of the workpiece before rolling). It is large and can be used for the forming of rings with small rolling ratio and complex shapes. It belongs to the field of mechanical design. 2. Background technology: [0002] Ordinary vertical ring rolling machine (hole reaming machine) is a rotary forging equipment with a long history. The pressure wheel and the passively rotating core roll form a pair of rolls, and the ring blank that is set on the core roll is rolled repeatedly. The thrust wheel on the side is against the ring to make the rolling process stable, and the signal wheel on the left side of the core roll controls ...

AI Technical Summary

Problems solved by technology

Although the multi-point radial rolling machine has been successfully used to produce such special rings, it has expanded the functions of ordinary ring rolling machines and can form rings that cannot be completed by ordinary ring rolling machines, but there is a problem: one machine Applicable ring size range is limited, and it is not easy to adjust the equipment when changing ring types
