It is well known that bolts are used to join mechanical parts and are also very important for the action of the machine. If the bolt connection is not good, it will directly affect the normal operation of the machine. However, it is distressing that bolts often break during production operations, and many users do not know what causes the bolt to break.
What are the factors that break the bolt? How does the bolt break? What are the types of bolt breakage? Today we will analyze the reasons.
1. The bolts used in different machines are divided into various grades. It should be noted that they cannot be replaced during maintenance. If the sloppy is not carefully confused and misplaced during the overhaul, it will inevitably result in poor positioning of the joint surface, and the joint surface is not tightly fitted, which may cause looseness in the mechanical operation and cause breakage of the connecting rod bolt.
2. The tightening torque is too large during assembly, and the uneven force is also one of the causes of bolt breakage. If the assembly worker does not have a strict torque wrench in the assembly, the specific tightening torque is not well understood. It is considered that the tighter the better, the longer the force rod will be used to tighten the connecting rod bolt. If the tightening torque is too large and exceeds the yield limit of the bolt material, the connecting rod bolt will yield deformation, which will break due to excessive elongation under the impact load. It should be emphasized that the connecting rod bolts must be tightened according to the standard. Do not think that the tighter the strength, the better.
3. If the machine fails during operation, it should be repaired in time. Due to mechanical failure, bolt breakage caused by failure to replace bolts in time often occurs.
Summary: When we use bolts, we basically cause the bolts to break when we don't know them. This is the case when the bolts are used at high speed. Each bolt or bolt of each type basically has The extent of its own weight or the range of heat, when these uncertain factors cause the bolt to exceed the range of the bolt itself, the bolt breaks or twists or even melts, which is the root cause of bolt breakage.
