Steel plate purchased back to the factory will be cuted into the required size by hydraulic shearing mechine,and then place the steel on the bending machine and bend into the desired shape.
The processed steel plate is placed on the die in the punch press for stamping.
Stamping process has punching, blanking, punching three processesPlace the preliminary processed steel on the roll mill, roll into a standard shape, and cut off according to the required lengthThe parts and components after stamping, bending and rolling are welded with protective welder to form each required part.
In order to improve welding quality and reduce spatter, 70% argon +30% carbon dioxide mixed gas protection welding is adopted in all welding sectionsThe workpiece is degreased by spray , treated 10-15 min, and then the workpiece is sprayed with water for decontaminatedIn order to enhance the corrosion resistance of the workpiece, some parts of the workpiece should be treated by powder spraying before assembly.
The epoxy resin material is non-toxic, odourless and pollution-free. Which is adsorbed on the surface of the workpiece by electrostatic spraying.
After the surface coating of the workpiece by the automatic assembly line into the curing room, the resin powder then 180℃/20min under the temperature of curing, forming a protective film.
The size, appearance, shape and other parameters of the finished product were inspected and measured, and trial assembly and bearing test were carried outThe finished products are packed with PET plastic-steel belt, bubble film , wrapping film etc. and stored for delivery.
