Hexagon nuts are one of our common nuts. They are used in conjunction with bolts and screws to connect and tighten the parts. They are mechanical parts that have internal threads and are used in conjunction with screws to transmit motion or power. Among them, type 1 hexagon nuts are the most widely used. Grade C nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; Grade A and B nuts are used for machines with relatively smooth surfaces and high precision requirements. , Equipment or structure. The thickness m of the type 2 hexagon nut is relatively thick, and it is mostly used in occasions that often need to be assembled and disassembled. The thickness m of the hexagonal thin nut is relatively thin, and it is mostly used in occasions where the surface space of the connected parts is restricted. China Hex Bolt Manufacturers introduces the processing steps of hexagon nuts.
1. Draw a line to find the center of the hexagon, make a proof, draw a check circle or check the frame line.
2. Calculate the diameter of the bottom hole according to the formula D=d-P, select a suitable drill bit to drill the bottom hole (use a small drill to drill the center hole before drilling the bottom hole) and chamfer both sides of the bottom hole.
3. Tap the M12 thread in the correct way, and lubricate it when tapping the thread.
4. According to the formula rod d rod = d-0.13P, check whether the diameter of the blank rod is qualified.
5. Process the hexagon head of the bolt first, the method is the same as that of the nut.
6. Set the M12 thread according to the correct method, and lubricate the thread when threading, and set the thread to the end.
7. Nuts and bolts are chamfered and trimmed.
8. Deburring, comprehensive re-inspection and smoothing of the workpiece.
