Hammer For Rock Drilling

 

 

When drilling into rocks or hard materials, you typically need specialized rock drilling tools, and a hammer drill is one of the primary choices for such tasks. Rock drilling hammer, is designed to provide the necessary impact force to penetrate hard surfaces effectively.In this way, rock drill bits for hammer drill bring great convenience to the user.

We use the hammer drill for drilling rock because it breaks up hard rock quickly, and drilling is fast and good. It is particularly powerful, can handle soft soil or hard rock drilling, and allows the drill bit to wear less and last longer. Using it saves time and effort, and drilling is safer. In short, the best hammer drill for rock is a drilling "artifact" that can make the work twice the result with half the effort.

 

 

The following will introduce the points that need to be paid attention to when disassembly the impactor, so that we can use the rock drilling impactor well.

1. Once the impactor is disassembled, it will be difficult to distinguish which end is the front joint end and which end is the rear joint end, so do some work on the outer sleeve. Make marks to identify the location of the front and rear connectors.

2. Remove the front joint, bit and retaining ring from the outer sleeve.

3. Remove the retaining stop ring and "O" ring from the drill bit shank.​

4. Remove the front joint from the drill bit.

5. Remove the rear connector from the other end of the outer tube.

6. Remove the check valve and reverse valve spring.

7. Remove the gasket.

8. Grasp the head of the valve rod and pull the cylinder of the valve rod out of the outer sleeve. Sometimes it is necessary to install the outer casing before use a copper rod at one end of the joint to gently tap the end of the valve rod to disassemble the valve rod assembly and the outer cylinder.

9. Remove the cylinder from the valve seat. The preferred method is to align the valve rod and cylinder assembly with the small diameter of the piston. Match the ends together, lift the assembly high and hit the piston downwards. At this time, the cylinder will be removed. It should be noted that put your fingers into the holes in the cylinder to prevent them from being pinched when the assembly moves up and down.

10. Turn to the end of the front connector and remove the guide sleeve from the outer sleeve of the impactor. due to corrosion of the part or if the guide sleeve is relatively dry, a special pull rod is required to remove the guide sleeve. When using this tool, do not hook the tool into the snap ring. Sometimes the guide sleeve can be loosened by banging the outer sleeve against a piece of hardwood.

11. Take out the piston from the outer sleeve. Because the piston is heavy, be careful when taking it out.

12. During daily maintenance of the impactor, it is not necessary to remove the valve rod from the valve seat. If the valve rod is worn due to when the valve rod is damaged and must be removed, you can use a hydraulic press or a hydraulic press to remove the valve rod from the lower end of the valve rod. Press it out. The disassembly of the impactor ends here.

Understanding the above points, I believe you have been able to initially grasp the use of rock drilling hammer.
