Introduction Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

The rig is the overall structure, can be adjusted in three dimensions, achieve 360 Â°
construction, and is equipped with steel crawler walking chassis, the machine moving quickly and convenience of construction in different environment, gripper adopts double clamping, can be achievedÂ remove the drill pipe and casingÂ automatically.The device usesÂ high pressure circulating water, and using dynamic impact on double tube rotary drilling constructionÂ in sandy pebble formation orÂ unstable fracture formation construction, ,Â The efficiencyÂ is higher than in the pastÂ conventional methods of construction.
Full hydraulic pressure control, solid fuselage structure.Advanced design concepts, monitoring instrument, convenientÂ toÂ operation, ensure the practical performance.The equipment adopts motor as the main source of power,Â And equipped with a 18 kw of small diesel engine as power when walkingÂ ,Â getting onÂ andÂ off.Â Total power of 90 kw motor, powerÂ ofÂ head rotation is 65 kw, so the drilling rigÂ rotary torque isÂ twice as large asÂ the same type , impact and the lifting force is very strong, high working efficiency, and can be multi-usage, give priority to with slope anchoring engineering construction, can also be widely used in construction of deep foundation pit, subway, tunnel, railwayÂ and the anchor construction of highway, geological disaster management and a small pile of construction.

The innovation points Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
Â
1. Use chassis of floating structure, can be change Angle of departure of drilling rig and approach angleÂ in a ccertain range;
2. Using large torque and hydraulic impact rotary power head, can adapt to more than 95% of the formation of construction;
3. The structure of multidimensional connecting rod Angle changed, can make the rig 360 Â° in three-dimensional space arbitrarily change the Angle of the borehole;
4. Using electric motor and diesel engineÂ can cope with different construction environment and construction conditions;
5. With double gripper can complete automatic shackle function;
6. Use chain times speed, large hydraulic feed, feed stable and reliable, which can realize double pipe drilling, andÂ followingÂ pipeÂ drilling.

Cold Drawn Steel Bar
Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.

For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.

To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).

For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.

We have more advantages on producing cold drawn steel bars:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm

3) Different cold drawing medias powder or oil to get different surface

4) Straightening machines to get better straightness up to 0.5mm/m

5) Grinding and polishing machines to get better roughness upto 0.4um

6) Heat treating furnaces to adjust the mechanical properties

7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

8) Multiple packages to avoid broken packages and anti-rusty
