The scope of application of the coiling machine

Abstract

The invention relates to a pipe coiling machine, which belongs to an equipment accessory. It is a machine for producing roll paper tubes, used in various industries. So, what advantages does it have? 1. Computer programmable controller control with remote control port; 2. Multi-point operation panel or digital remote control function, the operation is very convenient;

a kindtube coiling machine, belongs to the equipment accessories. It is a machine for producing roll paper tubes, used in various industries. So, what advantages does it have?

1. Computer programmable controller control with remote control port;

2. Multi-point operation panel or digital remote control function, the operation is very convenient;

3. The paper tube cutting machine adopts round knife to actively cut, which is more stable in cutting and more stable in performance;

4. The coiling machine has more than 80 function settings, and the machine can be set to run arbitrarily;

5. Stainless steel rubber basin, polyester rubber knife, high carbon steel rubber knife durable.

tube coiling machineAccording to the characteristics of rolling circle deformation, rolling circle process can be divided into elastic deformation, elastic plastic deformation, pure plastic deformation stage. In the initial stage of the barrel body blank twists and turns, the external tortuous moment is not large, the value of the internal stress is less than the yield limit of the data, only in the blank internal cause elastic deformation, called the elastic deformation stage.

When the value of the external tortuous moment continues to increase, the internal stress exceeds the yield limit, and the deformation in the deformation zone of the blank transitions from elastic deformation to elastic-plastic deformation and pure plastic deformation. The upper stress of the blank section transitions from the outer tensile stress to the inner lamination stress, and there must be a layer of metal in the center, whose tangential stress is zero, which is called the stress neutral layer, and its radius of curvature is indicated by P. The same, the strain spread by the outer layer of the tensile strain transition to the inner layer of the compressive strain, during which there must be a layer of metal strain is zero, that is, the coiling machine rolling deformation, the thickness of the same, known as the strain neutral layer, the radius of curvature with P.

tube coiling machineThe solenoid valve spool is always working, whether there is a blockage or installation problem in the solenoid valve spool part. When the valve core of the solenoid valve is blocked, it cannot move. At this time, the dust bag should be cleaned and reinstalled.
