How to roll the cone with a three - roll plate rolling machine
When we use the rolling machine to roll the cone, we must take the correct and appropriate methods and relevant skills, otherwise it is very easy to appear the phenomenon of rolling failure, or even cause damage to the machine. Three-roll plate rolling machine is a continuous point bending machine for the plate, the metal sheet can be rolled into circular, arc and conical workpiece within a certain range. So how to roll paper conical tube three roll machine? So let's look at that.
First of all, the conic structure is made up of many circles from top to bottom, from smaller to larger circles, and the circumference of the circle gets longer and longer as it goes from smaller to larger ends.

Generally, the plate roll bending machine can roll the cone barrel with small taper (30 degrees). After the cone barrel is unfolded, it is placed and rounded as shown in Figure 1. The key point of the rolling cone is that the linear speed of the large and small end is basically the same, because the linear speed of the roller is the same, so it is necessary to control the rolling speed of the large end.

It can be seen that the operator's technical and operational requirements are very high, and more dangerous. Therefore, in order to be safer and more convenient to use, it is recommended to use conical roller when rolling conical cylinder (Figure 2).

By using conical roller, the upper roller does not need to control the speed of the inner and outer ends, and the work can be easily completed by using this structure.
