Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.

1, the adjustment of the machine, in the installation, first of all to adjust the machine performance, this process must be patient and serious, check the machine is not a dust and used iron scrap, etc., to carry out the necessary clean-up to reduce Late troubles.
2, the slider stroke adjustment, pay attention to check the thickness of the mold and pay attention to check the ratio of the upper and lower modules is not normal, the module is normally controlled in the trip line switch point, this must pay attention.
3, the adjustment of the travel module, which is to adjust the upper point of the module, when the module reaches the highest point, set the switch, and set aside the slider's stop position, and also to slow down Modules to better protect the machine and mold.
4. The adjustment of the gap is mainly to measure the distance between the upper module and the lower module. The specific gap setting is determined according to the folded plate.
5, the angle adjustment, the adjustment of this angle has a certain relationship with the product, in general, folded 90 ° mold, then the middle angle must be greater than the two sides of the angle, then its elasticity can be adjusted according to the screws, in the bend When the pressure gauge is used, the pressure can be adjusted to prevent the mold from chipping.
What are the precautions for the installation and debugging of the CNC bending machine mould? The CNC bending machine mould is made up of many parts and components. Therefore, it is necessary to check the condition of the equipment during the installation, and strictly follow the steps to perform the installation and debugging. When paying attention to safety, CNC bending machine mold installation process.
