Many people may not be familiar with the threading machine. Friends who often work on the construction site know the threading machine. When many steel bars on the construction site are connected to other components, a threading machine is often used. The threading machine is a kind of machine that specializes in making pipe threads. After cutting the die on the die plate of the threading machine, the pipe threads are made. Therefore, the specifications of the die of the threading machine determine the specifications of the pipe thread. The threading machine die is the most common wearing part of the threading machine. Different threads have different threading machine die types and specifications.

Die set of threading machine
Â
According to the pitch, there are British dies (BSPT), American dies (NPT), and metric dies (METRIC); according to the size (inches): 1/4 "-3/8" (2 points-3 points die), 1 / 2 "-3/4" (4 points-6 points die), 1 "-2" (1 inch-2 inch die), 1/2 "-3" (2 inch half-3 inch die), 1/2 "-4" (2 inch half-4 inch die), 5 "-6" (5 inch-6 inch die).
According to the die material, there are tool steel plate teeth (for galvanized pipe , seamless steel pipe, round steel, copper, aluminum, etc. ), high-speed steel die (for stainless steel pipe , stainless steel round help wire ); There are 50A type die, 100A type die, MCC threading machine die, Q74 die, 114R die, Qingyang die according to the special threading model.

Working procedure of threading machine
Â
When the threading machine is working, first put the pipe to be processed into the pipe chuck, hit the clamp tightly, press the start switch, the pipe will rotate with the chuck, adjust the size of the die opening on the die head, and set the wire Mouth length. Then turn the feed handwheel clockwise to make the die cutter on the die head close to the end of the rotating tube with a constant force, the die cutter will automatically cut the thread, and the cooling system automatically sprays the die cutter to cool the wire, etc. When the mouth is processed to a preset length, the die cutter will automatically open, and the wire mouth processing is completed. Turn off the power, knock open the chuck and remove the tube.
The threading machine also has a pipe cutting function : put the pipe into the pipe chuck , hit the clamp, start the switch, lower the cutter holder on the knife feed device, and pull the knife hand wheel to move the blade on the knife holder To cut the length point, gradually rotate the handle on the cutter to make the blade squeeze the rotating pipe. The pipe is turned 4 times and 5 times and then cut by the blade.
The above is the related content about the threading machine die type and the working procedure of the threading machine introduced to friends. Hope that through the above content sharing, you can have a certain understanding of the threading machine and its die. Finally, we must pay attention not to exceed the rated range in the process of using the tool, once the machine exceeds the capacity of the machine, the machine damage will become very fast.
