How do steel processing plants make rivets and tools from round iron wires? There are mainly three steps.

First, the machine tears and straightens the raw iron, cuts them into fixed lengths, and then punches the mold twice to form the blank of the rivet rod. The machine runs in a blur and can produce 200 rivet rod blanks every minute. This is a processing factory that specializes in making rivet machine tools. Then the anchor blank passes through a zigzag rolling die, and grooves and fixing threads are pressed out on its surface. The next machine cuts the raw iron wire again and passes it through five punches in sequence so that the raw iron wire is punched into a hollow rivet body. These machines can produce 300 rivet bodies in one minute.

Second, next, the galvanized rivet bladders pass through a gradually widening gap. Smaller rivet rods will fall off from the start, while larger ones will fall off at the end. A magnetic loader sorts out the rivet rods of the correct size and discards the rejects. Next, the rivet bladders are inserted into the rivet body one by one by the machine. With the rapid rotation of the machines, the factory can produce millions of sets of rivets a day. The construction of the rivet tool begins with a prefabricated aluminum handle. The master inserts the steel sleeve which he will use as a gun for hydraulic fluid.

Third, the next part is the spring for the trigger, and then he screws an aluminum plate onto the base to secure the part. This is the pulling head of the rivet tool. There are tiny jaws on the inside that grip the rivet plate pulling head. After the installation is completed, the master pours hydraulic oil into the steel sleeve and inserts the air piston into the gun chamber. Next, the master places the base of the tool into the air chamber, then hangs an air hose and secures it with a steel frame. He connected the base of the tool to an air compressor and then pulled the trigger to compress the air, which would apply pressure to the hydraulic fluid inside to activate the rivet structure. As a result, a rivet gun that can drive rivets into steel plates was completed.
