Why is the molybdenum wire easy to loosen during wire cutting?
Wire cutting of molybdenum wire is a common metal processing method. It can be used to cut various metal materials, such as steel, aluminum alloy, etc. However, wire cutting of molybdenum wire is prone to loosening during use, which brings certain troubles to the processing process. This article will discuss the causes, effects and solutions of loosening.
1. Reasons
1. Mechanical stress
During the use of wire-cut molybdenum wire, it will be subjected to a large tensile force, which will cause deformation and relaxation of the molybdenum wire. On the other hand, the material and manufacturing process of the wire-cut molybdenum wire will also affect the degree of relaxation. If the material of the molybdenum wire is uneven or the manufacturing process is unreasonable, its tensile strength and wear resistance will decrease, which will easily cause relaxation problems.
2. Insufficient tension of wire cutting molybdenum wire
During the wire cutting process, the molybdenum wire needs to be cut under a certain tension. If the tension of the molybdenum wire is insufficient, it is easy to become loose.
3. Unstable current
Unstable cutting current may cause uneven heating of the arc on the molybdenum wire, causing local relaxation. Stable cutting conditions are essential to maintain the stability of the molybdenum wire.
4. Cutting speed problem
Too high or too low cutting speed may have an adverse effect on the molybdenum wire. Too high may cause thermal stress, while too low may cause mechanical stress, both of which may cause the molybdenum wire to relax.
2. Impact
Loose molybdenum wire in wire cutting will have a series of effects on the processing process. First, loose molybdenum wire will lead to reduced cutting accuracy, thus affecting the processing quality. Secondly, loose molybdenum wire is prone to breakage, which will not only cause damage to the equipment but also increase production costs. In addition, loose molybdenum wire will increase friction during the cutting process, thereby aggravating the wear of the equipment and reducing the service life of the equipment.
3. Solution
1. Choose good quality molybdenum wire material
Choosing good quality molybdenum wire material is the key. High-quality molybdenum wire material has high tensile strength and wear resistance, and can effectively resist the effects of tension and friction, thereby reducing the possibility of loosening.
2. Reasonable manufacturing process
Secondly, a reasonable manufacturing process is also very important. During the manufacturing process, the material of the molybdenum wire must be uniform to avoid internal stress concentration, thereby improving the tensile strength and wear resistance of the molybdenum wire. In addition, some auxiliary measures can be taken, such as increasing the diameter of the molybdenum wire and increasing the cutting speed, to reduce the force and friction of the molybdenum wire, thereby reducing the possibility of relaxation.
In short, it is a common problem that molybdenum wire is easy to loosen during wire cutting, but we can solve this problem by selecting high-quality molybdenum wire materials, reasonable manufacturing processes and taking some auxiliary measures. Only by ensuring the stability and reliability of molybdenum wire can the efficiency and processing quality of wire cutting be improved, thus meeting the needs of metal processing in different industries.
