What is metal spinning technology

1. What is spinning technology, also known as metal spinning forming or hot plate technology:
By rotating the workpiece so that the force point from one point to a line by line to a plane at the same time in one direction with the hob pressure to give a certain degree of metal deformation and flow in this direction while forming the shape of a technology. Here, the metal material must have a plastic deformation or flow properties, spinning does not mean that the plastic deformation, which is a deformation of the plastic deformation and flow of complex processes, in particular, should be noted that we are talking about spinning technology is not a single strong spin and ordinary spin, which is a combination of both; powerful spin for a variety of cylinder, cone shaped body of the spinning shell processing technology, is a relatively old mature methods and processes, but also called the hot-plate test.

2. Spinning forming the main features:

1. Spinning part of the continuity of local processing, instantaneous deformation zone is small, the total deformation force small.

2. A number of difficult and complex shape parts or difficult to deformation of materials, the traditional process is difficult if not impossible process, using the approach to spinning can be processed out, such as the pulley, lighting accessories.

3. Spinning process can achieve very little tolerance of IT8 or so, the surface roughness of less than 3.2, the strength and hardness are improved significantly.

4. Spinning high utilization rate of processing materials, mold can cost more than a fifth less than the stamping dies. Spinning the economy and production batch \ workpiece structure \ equipment and labor costs are. The majority of processing spin processing and pressing processing, Shears processing, ultrasonic cleaning, plating and processing technology supporting applications to get the best value for money.

Five. May be the shape of the spinning process can only be rotating body, mainly barrel, round vertebral line, bus-like and combination-type song.

6. Machinable materials include: iron, aluminum, stainless steel, copper and so on.
