Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, and more specifically, to a high-precision positioning fixture for forging processing with a simple structure. Background Art

[0002] Forging is a processing process. A forging is an object in which metal is subjected to pressure and shaped by plastic deformation to the required shape or a suitable compressive force. This force is typically achieved by using a hammer or pressure. The forging process creates a refined grain structure and improves the physical properties of the metal. A positioning fixture is required during forging processing.

[0003] Based on the above, the inventor found that: the existing positioning fixture clamps and fixes the forging through a fixture, which is convenient for subsequent processing. However, one type of fixture can only clamp and fix one shape of forging. Facing forgings of different shapes, the fixture needs to be replaced, and the operation is relatively cumbersome. Therefore, in view of this, the existing structure is studied and improved, and a high-precision positioning fixture for forging processing with a simple structure is provided, in order to achieve a more practical value.
