Technical points

     1, the final size of the cutting and processing of metalworking departments should be correct, all aspects of the steel pipe should meet the technical requirements of

         the product to ensure that the process does not appear in other departments is due to problems arising from the metalworking sector.

     2, the steel pipe in the phosphating process should pay attention to the order of the phosphating pool and soak time in each phosphating pool.

     3, the welding size should be correct, the welding is required to be plastic and polished, no bubbles, welding slag, gaps and so on.

     4, pre-heat spray powder treatment, gunmen one side and the distance to be controlled, products in the oven time should be deployed well, remove the product

        should be gently, to keep the surface of the product does not scratch, no dust, etc. ,

        In the process of transport products are not free to fall, do not bump and so on.

     5, sewing cloth size should be correct, and to ensure that the fabric clean and tidy.

     6, the assembly sequence should be correct, the steel pipe assembly process should be taken lightly, not arbitrarily lit, to avoid being sprayed steel tube surface bumps,

         after the completion of the assembly product balance is reasonable, not rollover.

        (Folding products should be guaranteed to be easily folded, each part will not interfere with each other.For some tables should ensure that the table legs and the box 

        can be naturally placed in the table frame, as required.)

Process flow

       Handrails: Cutting → Strapping → Double Bending → Correction → Strapping

        Front rail: cutting → binding

        After the crossbar: cutting → binding

       Back rail: cutting → binding

        Wear cloth: cutting → bundling → drilling → deburring → double bend → single bend → roll → correction → strapping

        Rear leg: cutting → strapping → double bend → straight cut → calibration → drilling → deburring → punching → binding

        Metalworking workshop → Phosphating workshop (degreasing → pickling → neutralization → surface conditioning → phosphating) → welding 

        (1, front rail and iron stamping welding 2, rear foot welding pin welding nut 3, after the foot tube and the rear File welding 

        4, the front rail and the armrest welding 5, the rear legs and handrails welding) → → → spray grinding → handrail, before and after the cross-section, 

        after the tube wrapped around the non-woven fabric → assembly
