Torque wrench is a torque tool that we are all familiar with. At the same time, it is also a relatively expensive product. Therefore, when we use it, we should pay more attention to it, and more maintenance is necessary. Today, Xiaobian is the torque wrench that we are talking about. When we need to pay attention to where, we all know that the torque wrench has a close relationship with the use of the environment and the frequency of use every day. Under normal circumstances, the torque wrench can be used about how many thousands of times, this is not a fixed number . Different manufacturers are completely different, and the same manufacturer is more different. Shanghai Shiheng Electronic Technology Co., Ltd. has been engaged in the torque wrench industry for four or five years. We must pay special attention here to remind everyone that we must cherish our torque wrenches. So what matters should we pay attention to? Please read on:
When using the torque wrench, note the following four aspects:
1. When pulling the wrench, use a soft and even force. Never use a short, impulsive force to pull because the jerk will produce an impulse. At the moment of stopping the force, the screw or bolt may have twisted past its head.
2. Contaminants can prevent accurate torque values. If the parts and screw holes are contaminated, it will not be possible to have the correct torque value.
3, friction is a common phenomenon, but there are also good and bad effects. The good thing is to keep the parts together; the bad thing is that, when twisted, it can give you erroneous results. A mechanic's hand-tightening connection has only 10% to 20% of the tension applied, and in many cases, 40% to 50% of the torque is used to overcome the friction between the bolt head and the part, along the bolt. The threaded surface of the mating screw hole also generates additional friction. Therefore, when tightening the bolt, all these friction factors and other factors should be taken into consideration.
4. When tightening nuts or bolts with damaged or obstructed threads, pay attention to how much additional torque is required through the damaged area and add this additional torque to the recommended torque value.
