Why does the high-frequency breaker break if it is not used for a long time

We all know that many high-frequency breaker manuals will repeatedly emphasize that when the breaker is not in use for a long time, the nitrogen must be released and the piston pushed into the cylinder, but why do you do this, and why do you do this? Too clear, in this section we will talk about the necessity of doing so. First of all, let's popularize the material and heat treatment process of the piston of the breaker. Because the piston of the breaker needs to hit the drill rod for a long time, it is required to have both high hardness and good toughness. The commonly used models are currently at home and abroad. Most of them use low-carbon alloy steel carburizing to produce pistons. The surface hardness of the pistons in this way can reach HRC59-62 degrees, and the hardness of the core modulation treatment is about HRC30-35. The hardness of the drill rod exceeds the hardness of the piston, and the piston will be damaged in a short time. Some customers blindly require high-frequency treatment on the surface of the drill rod with high hardness, so that the surface hardness of the drill rod reaches above HRC58, which is very easy to use. Piston damaged. High Frequency Breaking Hammer Manufacturers

Because carbon is a necessary auxiliary element in metal elements, such as No. 45 steel, which contains 0.45% carbon, because metal elements with high carbon content are easily oxidized and rusted, and the piston is made by carburizing process, so the surface of the piston Once damp, it is easy to rust, especially in summer and autumn, if it is not used for more than 10 days and the surrounding environment is very humid, it is easy to rust the piston. It will roughen the oil cylinder, or even scrap it. So the correct way is, if you don’t use the breaker for more than 10-30 days, you should release the nitrogen, then remove the chisel rod, remove the plug on the hammer oil pipe, and use a steel pipe or iron rod to extend through the jacket Hold the piston, and use a sledgehammer to push the piston back to the upper limit. After the operation, install the chisel rod. When you use it next time, it can be used as soon as it is filled with nitrogen, so that even if the periphery of the piston is rusted, it will not damage the oil seal and oil cylinder. . If it is troublesome, you can also wrap the hammer with waterproof canvas or oilcloth to prevent moisture intrusion when not in use, which can also prevent it.

When carrying out high-frequency breaker operations, many operators think that the problem of breaker air strike is not serious. Such a wrong understanding also leads to wrong operation actions. The chisel is not always kept perpendicular to the broken object, and is not tight The operation is not stopped immediately after the object is pressed and broken, and the situation of empty punching occurs from time to time. The air strike problem does not seem to be serious, and it does not cause much damage to the breaker itself. In fact, this wrong operation will cause the main body bolts to loosen, the precursor to be damaged, or even damage the machine! It must be taken as a warning.
