Problems solved by technology
Its obvious shortcomings include: low production efficiency, poor product quality, high scrap rate, high energy consumption, high auxiliary costs, high labor intensity, and environmental pollution.
There is an existing method of quenching the molds together after molding. Although it can handle the heat treatment deformation of the sheet material, it is produced in a separate process, cannot work continuously, and has low production efficiency.
Existing sheet material continuous heat treatment control deformation equipment is generally suitable for the production of small and medium-sized sheet materials. If the above-mentioned equipment is used for saw blades of φ1000mm to φ4000mm, the equipment investment will be large and the site will be occupied.

The apparatus includes a pedestal, a bearing guide post on the pedestal, a movable lower bearing plate on the bearing guide post, a first holder on the lower bearing plate for downward spraying cooling liquid, a jack connected to the lower bearing plate, a movable upper bearing plate on the bearing guide post, a second holder on the lower bearing plate for upward spraying cooling liquid, and pressing unit connected to the upper bearing plate. The present invention can lower the deformation of large saw blade plate material in continuous heat treatment, and has continuous operation, high yield, low power consumption, high quality, low cost and other advantages.
Description
technical field [0001] The invention belongs to heat treatment equipment and methods, in particular to a device for continuously controlling and preventing deformation of sheet materials during continuous heat treatment of sheet materials, in particular to a deformation control method and device for continuous heat treatment of extra-large saw blades. Background technique [0002] The original chip heat treatment production process—heating in a salt bath furnace—manually taken out and placed in quenching to cool—then taken out and put into a hydraulic press for pressurization and shaping (passive shaping)—after taking out, washing with water to remove salt—manual initial forging. That is, deformation correction is performed after heat treatment. Its obvious disadvantages are: low production efficiency, poor product quality, high scrap rate, high energy consumption, high auxiliary costs, high labor intensity of workers, and environmental pollution. Existing one uses the mold...
