HH-3/16h Automatic High Speed 1-Die-2-Blow Cold Heading Screw Making Machine
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.
