Self-tapping screw making machine bolt cold forging machinery

    Production flow 

Brief introduction of processes and machines needed:
      (1). Pull the coarse line to the line patch needed. (Wire drawing machine)
      (2). Adjust, produce, and form the head of screw on the heading machine. (Screw heading machine)
      (3).Grind tooth on the coil thread rolling machine, and form the screw completely (Thread rolling machine)
      (4). Treat the semi-finished screw in the heat treatment according to the standard (Heat treatment furnace)
      (5). According to the requirements, process plating etc. (Zinc plating machine)
      (6).  Packing and out of factory 

Functions of heading machine:

(1). The machine belong to the cold heading machine, the function is the first molding and the second punching products, which is mainly used for forming the heads of the screw products, the work principle is line materials calibration, accessing lines, sending materials to the main mold, first punching initial forging, and second punching the formed blank materials and withdraw. The work gets done without any letup, the production capacity can be up to about 150-180pcs per minute, which belongs to the more advanced products in the current technology.

(2).  Upsetter various materials: Common steel, carbon steel, stainless steel, copper, aluminum, and alloy steel etc with widely functions. (For the stainless steel and alloy steel, can heat them to the appropriate temperature with the heater, and can upsetter.)

(3). The machine can make the common products such as the common self-tapping screw, electric screw, micro-screw, socket head cap bolts, self drilling screw, fiber plate screw etc. For an example PKO can upsetter other non standard abnormal hardware and metal products.
