Abstract
The invention relates to the technical field of heat treatment equipment, in particular to a PLC-controlled large-scale circular saw blade multi-oil-cylinder hot-pressing tempering furnace. According to the PLC-controlled large-scale circular saw blade multi-oil-cylinder hot-pressing tempering furnace, a tempering upper pressure plate, a tempering lower pressure plate, a portal frame walking mechanism, a PLC electronic control system and a touch screen are arranged; the flow of each oil cylinder is controlled by the PLC electronic control system, so that the stroke of the oil cylinders can be synchronous; the pressure of the oil cylinders can be changed with the furnace temperature. Through the adoption of the tempering furnace, the problems of poor flatness of tempered saw blades, unchanged pressure of the oil cylinder in the tempering process, and low automatic degree of the tempering manner which are caused by poor heat treatment tempering quality are solved, so that the heat treatment tempering quality is improved, tiny cracks of the saw blades are avoided, the energy consumption in a heat treatment tempering process is reduced, the automatic degree of the heat treatment tempering process is improved, and the work environment is improved.
Description
technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a PLC-controlled large-scale circular saw blade multi-cylinder hot-press tempering furnace. Background technique [0002] The large-diameter circular saw blade here specifically refers to a diamond circular saw blade substrate with a diameter of 2600 mm to 5200 mm. The diamond cutter head is welded on the outer ring of the base body of the diamond circular saw blade to become a diamond circular saw blade. Large-scale diamond circular saw blades are important tools for stone mining and large-scale stone plate cutting, and are increasingly used. The substrate of diamond circular saw blades is the basis for manufacturing diamond circular saw blades. The quality of the substrate directly affects the performance of diamond circular saw blades. Heat treatment is one of the key processes in manufacturing the diamond circular saw blade base. The quality of heat treatmen...
