Description

TECHNICAL FIELD

[0001] The utility model relates to die steel deformation correction technical field, and specifically is a die steel deformation correction device with good stability. BACKGROUND

[0002] Die steel deformation correction refers to the deformation of die steel caused by material processing or heat treatment during die manufacturing, which needs to be restored to the design size and shape of die steel through a series of correction processes and methods to ensure the precision and performance of the die. Common correction methods include post-heat treatment cutting, electric spark machining, cold bending correction, etc. The specific selection depends on the type and degree of deformation and the specific requirements of the die.

[0003] For example, the die steel deformation correction device disclosed in the announcement No. CN212042088U includes a workbench, a fixed clamping plate fixed on the workbench, and an electric push rod fixed on the workbench. The front end of the electric push rod is slidably provided with a movable clamping plate. A screw rod seat is fixed on the electric push rod. The utility model is provided with a turntable, which facilitates the rotation of the driving gear. When the driving gear rotates, it can drive the driven gear to rotate. The rotation of the driven gear drives the screw rod to slide, thereby extruding the deformed die steel and correcting it. The rear end of the screw rod is fixed with a driven gear. The electric push rod is rotatably installed with a driving gear. The driving gear and the driven gear are meshed and connected. The diameter of the driving gear is smaller than that of the driven gear, making it more convenient to control the sliding distance of the movable clamping plate relative to the front end of the screw rod, and the accuracy is higher. When the width of the die steel changes, the position of the movable clamping plate on the screw rod can be adjusted more accurately and conveniently.

[0004] However, this patent only limits the movement trajectory of the movable clamping plate when extruding and correcting the die steel, and does not have a limiting and adjusting mechanism for the die steel. Without proper limiting and adjusting mechanisms during the correction process, the die steel may move or deform during the correction process, resulting in unsatisfactory correction results or even new deformation, greatly reducing the stability and reliability of the operation.
