The tension controller is a high-precision instrument with digital, automatic control for web tension. It can be widely used in tension control of the printing, packaging, paper, textile and dyeing industries. Web tension controller adopts the CPU of 16-bit or 32-bit, with high speed, high precision, high reliability.
Why Choose The Automatic Tension Controller
A typical tension control system is mainly composed of a tension controller, a tension reader, a tension sensor, a magnetic powder brake, and a clutch. Depending on the loop, it can be divided into types of open loop, closed loop or free ring. According to the monitoring method of different coils, it can be divided into types of ultrasonic, floating roller, tracking arm. The stability of tension control has directly affected the quality of the slitting products. If the tension is insufficient, it will generate drift in the raw materials moving and the finished paper wrinkle will appear after the rewinding. If the tension is large, the raw material is easily broken, so that the finished products will appear more broken ends after the rewinding.
The Performance Of The Automatic Tension Controller
The tension controller refers to the durable control of the tension performance when the feedstock is stored on the device. This control is required to be valid for any operating speed of the machine, including the deceleration, acceleration, and uniform speed of the machine. Even in emergency parking conditions, it should be guaranteed that the parties are not damaged.
The automatic tension controller is a control instrument that can directly set the tension value of the controlled machine, then directly output the signal of the tension sensor as a tension feedback value, after the proposed bias, outputting to the PID controller for disposal. Then input to the core executive agency to control and finally arrives the purpose of a small bias.
Function Of The Automatic Tension Controller For Unwinding And Rewinding
In the control industry, in some strip-shaped and line-shaped products, tension control is required to achieve production requirements. The general tension controller also has a volume extent function, which is generally applied to the down coiler equipment, with unwinding and winding types. The tension controller also has a taper adjustment function that can be sent directly to the winding taper on some processes inside the controller.
Fully automatic tension control is the actual tension value of the material, measured by the tension sensor directly, and then converts the tension value into a tension signal feedback to the tension controller. Through the comparison of this signal and the pre-set tension value, calculates the control signal. The automatic control execution unit makes the tension value is equal to the pre-set tension value, to achieve a stable purpose for tension control. A fully automatic tension controller is an advanced tension control method.
The fully automatic tension controller measures the actual tension of the coil materials and automatically adjusts the tension value of the coil according to pre-set tension value through the PID algorithm. It has extremely high accuracy tension control, suitable for applications where have high requirements for the accuracy of the tension controller.
How To Solve The Malfunction Of The Automatic Tension Controller
1. The automatic tension controller adopts the AC 185-264V power supply. After the current is switched on, if the tension controller does not work, check if the power supply is connected correctly or whether the fuse is abnormal.
2.If the display signal is incorrect, can re-set the correct signal range. Check the route and the tension sensor whether there is a signal fault or replace the tension sensor.
3.If the tension controller has no signal output, usually there is a connection problem, so check whether the signal output connection is correct, then turn off the voltage for ten seconds and then switch on.
4.If the tension controller signal output is unstable, check whether the roller, bearing and magnetic powder clutch, brake, or driver have an abnormality. Replace the tension sensor or re-calibrate the signal range.

Therefore, the material selected will have high power resistance after heat treatment. The mold material should have outstanding hardenability to ensure that the mold can be hardened and uniform.
2.Excellent wear resistance
The mold should have high wear resistance to ensure normal service life and produce large quantities of extruded parts. In general, the hardness of steel is proportional to wear resistance under certain conditions. Therefore, mold materials must have sufficient hardenability. In addition to the hardness, The decisive factors are the thickness, composition, amount of excess for the matrix after heat treatment and the amount, size, type, dispersion, red hardness of carbide. The tungsten carbide has a content of more than 80% of WC, the wear resistance of which is several times higher than steel. So to get a long service life for the drawing mold, and carbide is mostly adopted for the materials.
3.Sufficient thermal stability
For continuous production, the temperature of the mold sometimes will reach 200 ° C, which will reduce the strength and hardness, so that the mold material should have outstanding thermal stability. Carbide drawing dies have sufficient thermal stability for high-temperature resistance.
4.Excellent processability
Cold extrusion mold has a long manufacturing time with high accuracy requirements. Usually, it is necessary to cast, cutting, heat treatment, grinding or other fine finishing. So only the materials that have good processability can meet the production needs. The excellent process of carbide molds will be the best choice.

How To Improve The Performance Of Tungsten Carbide
In order to adapt to the harsh environment under different working conditions, tungsten carbide often needs to be reprocessed to make corresponding changes for the original performance, so what are the methods to change the performance of tungsten carbide?
1. Improve the quality of raw materials
Improve the purity of raw materials
High-strength, high-impact toughness alloys have high requirements for the purity of raw materials, while continuous cutting tool with low impact load but high machining accuracy, have low requirements for raw material purity.
Control the particle size and distribution of raw materials
It should avoid excessively large particles in the carbide or cobalt powder raw materials, and prevent the tungsten carbide from forming coarse carbide grains and cobalt pools during sintering.
At the same time, the size and composition of the particle materials should be controlled to meet the needs of different products. For example, carbide cutting tools should adopt tungsten carbide powder with a fisher particle size of less than 2 microns, wear-resistant tools should use tungsten carbide powder with a particle size of 2-3 microns, and mining tools should adopt tungsten carbide powder with the particle size of larger than 3 microns.
2. Improve the structure of the tungsten carbide
3. Improve or select new hard phase and binder phase
The performance of tungsten carbide is affected by the composition and structure of the hard phase and the binder phase. Generally speaking, when the content of the hard phase is high and the grains are finer, the hardness is high and the wear resistance is good, with poor impact resistance. Improving the hard phase and the binder phase is one method to change the performance.
4. Surface hardening treatment
To solve the contradiction between wear resistance and toughness, hardness & strength of tungsten carbide, surface hardening treatment can be adopted.
The coating is physically or chemically depositing a layer of TiC or TiN on the surface of the cemented carbide to increase the wear resistance. The most rapid development at present is the coated tungsten carbide.
