Description

Workpiece clamping fixture for sawing machine

Technical Field

The utility model relates to the field of sawing machine fixture brackets, in particular to a workpiece clamping fixture for sawing machines.

Background Art

As a cutting machine for parts processing, sawing machines are widely used in steel, steel, plate and other processing industries. They are mainly used for sawing round materials, square materials, profiles and pipes of ferrous and non-ferrous metal materials. When sawing these workpieces, the workpieces need to be clamped and fixed first.

In the prior art, the clamping jig for fixing the workpiece is generally a straight structure, and the two sides of the pipe are clamped by two vertical plate structures. However, when the clamping jig with a straight structure is used to fix the curved workpiece, there are fewer contact points with the curved workpiece, and the curved workpiece is easy to move during the sawing process, which greatly reduces the fixing effect and cannot guarantee the cutting quality. In addition, the debris generated during sawing falls directly on the ground, affecting the cleanliness of the working environment.
