Abstract

The invention discloses a radial forging device, which relates to four-side forging forming of various metals, and realizes radial forging forming of four hammers by using a radial forging device through applying a unidirectional forming force by using a general unidirectional downward pressing type or upward pressing type press.

Description

Technical Field

The invention relates to the technical field of forging equipment, in particular to a radial forging device.

Technical Field

In the prior art, the common free forging only comprises the opposite movement of an upper anvil and a lower anvil to forge and form various metals in the middle, because the periphery is not restrained, the metals flow to the periphery, under the condition of large reduction, the flowing easily forms cracks and strain defects at the central part of the deformed metals, if four hammers are used for forming, the metal flowing in two directions can be reduced, the restrained forging is formed, and the quality of metal deformation is improved. The existing four-side forging forming device has the following defects: (a) the forming forces in two horizontal directions are transmitted through the inclined plane, the mechanical efficiency is low, and the heated adhesion blocking (b) has large maintenance amount and unstable use. Additionally, GFM corporation has a proprietary product: a radial forging machine (also called a precision forging machine) applies pressure through four hammer heads which are respectively driven to forge and form a workpiece on four sides, and the four hammer heads are in a mechanical synchronous type and a hydraulic synchronous type. However, such a radial forging machine (also called a precision forging machine) is expensive in cost and requires a high level of use.

Therefore, the invention of the radial forging device using the common hydraulic press or the quick forging machine has great significance for improving the forging efficiency, helping the hard-to-deform metal to reduce the internal defects and increasing the primary rolling reduction so as to improve the productivity.

An external manipulator or a loading and unloading machine is matched with a hydraulic press to realize forging forming, when the hydraulic press enables the movable cross beam 6 to descend, the movable cross beam 6 drives an upper anvil head 8 to apply deformation force to the middle metal through an upper anvil 7, and meanwhile, the deformation force of the deformation metal is transmitted to the workbench 1 through a lower anvil 10 and a lower anvil 2.

The lower chopping block 2 and the upper chopping block 5 are connected with the synchronizing rod 3 through the rotating shaft 11, the synchronizing rod 3 is provided with the left anvil 4 and the right anvil 9, the left anvil 4 and the right anvil 9 are respectively provided with an anvil head, when the movable cross beam 6 descends, the upper chopping block 5 drives the synchronizing rod 3, the left anvil 4 and the right anvil 9 to move simultaneously, so that the upper anvil 7, the left anvil 4 and the right anvil 9 are fed simultaneously and are constrained and forged together with the lower anvil 10, and four-side forging is realized.
