Description

Arc suppression frock

Technical Field

The utility model relates to the technical field of machining, especially, relate to an arc suppression frock.

Background

The arc-shaped plate is a common workpiece in the mechanical field, and is pressed on a press machine by matching a male die and a female die. Before pressing, a workpiece to be pressed is fixed on a female die by using a screw, and the workpiece is detached from the die by using a tool after the punching is finished. If the pressing force of the screw is insufficient, the workpiece may be wrinkled during pressing, and during dismantling, the pressed workpiece is tightly attached to the die, so that the workpiece is easily deformed or damaged during dismantling by using a tool. The existing pressing mode is poor in pressing effect and low in yield, manual fixing is needed before pressing, and a workpiece needs to be manually taken after pressing, so that the processing efficiency is low, and the production period is long. The existing processing mode is urgently needed to be improved, and a pressing tool which is beneficial to simplifying pressing operation, improving pressing effect and improving pressing efficiency is designed.
