1 Die 2 Blow Self Drilling Tapping Screw Heading Machine

Automatic 1 Die 2 Blow Tapping Self Drilling Screw Making Cold Header Machine For M4

1. The metal material used to make screws generally uses wire that has been made into a spiral award in advance. Because the wire will be deformed and thickened after forging, we need to choose a slightly thinner wire for the screw shaft according to demand when making screws. .
2. The wire diode screw wire that has been transported to the appropriate length position is straightened by the machine and then sent to the cold heading machine equipment
3. The first punch movement prepares the wire, and then the second punch movement forges the wire again and forms its finished product. The number of dies in cold heading, a fixed die (pressing die) and a stamping (flattening) die (punch) is not the same. Some complex screws may require multiple punches to form, which requires multi-station equipment to form the screws.

Processing

1. After the movement of the punch, the head of the screw has been completed, but the part of the screw shaft is not yet threaded. The forming method of the screw thread is to twist the thread.
2. The thread rolling is the use of two rotating thread-engraving die (screw wrenches) with relatively rotating threads to squeeze the cylindrical blank formed by multi-station or heading machine in the middle.
3. After the heading and rubbing the teeth, the entire screw has been produced. Of course, in order to make the screw look brighter and have better performance, surface treatment procedures are generally done.
4. Such as the cleaning and passivation of stainless steel screws, and the surface plating of carbon steel screws. Made into various colors of screw fasteners.

Attention

When producing screw fasteners, it should be noted that the molds required for each screw are different, so non-standard screws will need to be produced separately.

Packing

Wrapped by stretching plastic films

Port: CHONGQING/NINGBO/ SHANGHAI

Main functions of cold heading machinery
