Fragmentation at the end of zone A

During the operation of the breaker, the concave core of the piston core is not repaired in time or the piston head is broken, Drop the block and hit the steel tail.

No warranty as shown

shiyou

Partial fragmentation of zone A

The wearer's guide sleeve is seriously worn and not replaced in time, and the gap between the guide sleeve and the steel is too large to cause partial tail damage.

No warranty as shown

shiyou

Flat pin position in area B

When the breaker is produced, the steel brazing is not pressed against the broken object, or the steel brazing is slipping on the broken object, so that a strong impact force cannot be transmitted to the crushed object, and the steel brazing is broken or broken due to a serious collision between the brazing pin and the flat pin.

No warranty as shown

shiyou

Flat pin fracture in area B

Improper operation and fatigue fracture, the gap between the flat pin and the guide sleeve is too large, the steel brazing is torsion and the force is not uniform, causing the steel to break.

No warranty as shown

C-area pry off

The steel brazing material obtains higher strength and hardness after heat treatment, and should maintain a vertical working angle during operation.
Any side force and local fatigue generated by the operation method of the steel brazing rod as the lever, the oblique angle, and the pulling operation are used for the brazing. Cause breakage.

No warranty as shown

C-area tip breakage

The hardness of the steel tip is higher than that of the corner or the cone. The new steel brazing is not suitable for the impact force. The rock is too hard or improperly operated, causing the tip to be tipped and dropped.

No warranty as shown

shiyou

C-area curling edge

The steel brazing encounters the crushed material with higher hardness, and the point is continuously hit for more than 30 seconds without breaking. The impact force causes the high frequency friction between the steel brazing material and the crushed object to generate heat energy, and the heat of the steel tip can not be released in time, resulting in The high temperature annealing of the steel tip has a curling edge.
