Common Phenomena of breaking hammer chisel damage

The use of breaking hammers is faced with a more complex working environment and relatively high working pressure, and its loss is inevitable. However, once the quality of the machine itself is unqualified or the maintenance is not paid attention to during use, it will inevitably increase the loss of accessories and affect the overall work efficiency. Let’s take a look at several common breaking hammer chisel damage phenomena.

1. Breaking hammer chiselfracture phenomenon:

When the strength of the raw material is insufficient, cracks will occur after heat treatment, and the damage of this crack will appear immediately when the breaking hammer chisel is used.

There are defects inside the drill pipe material, and the vacuum degassing effect during the steelmaking process is not ideal, resulting in bubbles in the material. This kind of material will crack along the gas point after heat treatment, and it is easy to break when using drill pipe, and the fracture is also cut. The breakage of the drill pipe from the flat sheath is due to impurities contained in the raw material, which may produce tiny cracks on the surface of the breaking hammer chisel that are difficult to detect with the naked eye.

2. Cracks in the breaking hammer chisel

When there are particles of impurities in the drill pipe of the breaker, the small particles of impurities in the hammer will appear between the piston and the top of the drill pipe, resulting in small fracture cracks on the top of the drill pipe.

This phenomenon does not happen all at once, nor does it happen in a short period of time. The user should always pay attention to the operation situation to prevent the situation from deteriorating and not to cause unnecessary damage to the breaker. If problems are detected beforehand, they can be prevented. For drill pipe quality problems, breaker manufacturers recommend that users report to the equipment manufacturer in time and replace faulty parts in time.

3. The collapse phenomenon of the drill pipe pin of the breaker:

When the hammer hits the hole, the piston transmits the impact force to the drill pipe, and the hammer drill pipe transmits the impact force to the drill pipe pin. Drill pipe pins are easily broken under strong impact force.

When the breaker drill pipe pin is impacted, the impact force will be distributed to the cross pin of the drill pipe pin. At this time, the cross pin of the drill pipe of the breaker will push the inner hole of the cross pin of the drill pipe, causing the spring block on the edge of the inner hole to crack.
