HZ-15 concrete electric core drilling machine is a new construction machine for mechanical drilling of concrete. It is easy to operate, light and flexible, accurate drilling and sampling, smooth surface after drilling, and no accidents on the drilled material. Damaged, it is an ideal construction machinery drilling rig is powered by a series motor, with artificial diamond stone wall drill bit
HZ-15 concrete electric drill corer technical parameters:
★ Large hole core diameter 150mm
★ Large hole core depth 400mm
★Electronic power meter 2.2kw
★ voltage 220V
★ Weight: 100kg
Preparation for HZ-15 concrete electric drilling core coring machine:
★ In order to ensure safe and normal work, read the instruction manual before use, familiar with the structure and use of the drilling machine.
★ Wipe all parts of the rig clean, and the rack part of the column is lubricated with No. 20 mechanical oil (GB443-64).
★In the hole to be drilled, first use a drill to make a ∮19×50 hole. Move the rig to the working position, adjust the support screw, and observe the level with the level. At this time, the two rollers should be off the ground, then press the expansion bolts on the ∮ The 19×50 hole is tightened.
★ After the rig is fixed, connect the faucet to the water source, unscrew the water source switch, check if there is water flowing out, if any, it is normal.
★ Install the drill bit according to the size required for punching.
★ Turn on the circuit, turn on the electrical switch, run for a few minutes, and turn the feed handle to check whether it is flexible and reliable. If the parts are flexible, operate in the direction.
HZ-15 concrete electric drilling core machine Note:
★When the hole is used, the resistance should be small, the cutting is stable, and the feed speed during drilling is about 4-5m/min. When the drilling is nearing completion, the drilling will be slightly vibrated due to the change of cutting force. Speed, when cutting is completed, the drill should be lifted quickly until the cutting edge is out of service, and the drill is turned off and the water source is shut off.
★ The entire drilling process must be kept fully water cooled. Observing from the drilling object slot means that the water supply is insufficient and it is necessary to stop the drill for inspection. However, when the drilling is completed, the water flows into the lower layer without overflowing, which is normal.
★ When drilling the drill bit and drilling the drill bit quickly, do not stop, but wait for the drill bit to just leave the work, stop the spindle rotation, and then raise the drill bit.
★When drilling, if the drill bit is found to be stuck, the drill should be lifted quickly for a while, then slowly drilled in. Avoid hard drilling and then break the drill bit.
★ If the motor temperature exceeds 70 °C during the drilling process, it should be temporarily stopped and used after cooling.
★Toggle the switch button, and rotate the operation handle in the forward direction to make the drill bit slowly contact the surface of the concrete. After the cutter blade is inserted into the groove, the drill can be pressurized.
★If during the drilling process, the drill bit cannot be drilled, the diamond part of the drill bit surface is not completely exposed. It is necessary to use a strong wear material (such as refractory brick, grinding wheel, etc.) to open the surface of the drill bit surface. Touch the surface layer and have a rough feel before you can drill.
HZ-15 concrete electric drilling core machine maintenance and maintenance:
★ If there is some vibration during the drilling process, after the drilling is finished, the joints must be carefully checked and the fastenings adjusted in time.
★ The rig should be kept clean. When the drilling is completed, the parts of the rig should be wiped clean, and the moving parts should be lubricated with oil to be placed in a dust-proof and dry place, covered with a plastic film cover.
★Before inserting the drill into the spindle, add calcium-based grease to the two joint threads and tighten them for easy disassembly.
★ When the rig is stopped for a long time, the insulation resistance between the winding and the casing must be tested. The value should be no less than 5 M.
★ If the drill bit is worn and cracked seriously, the drill should be replaced to avoid damage to the motor during drilling and it is not possible to continue working.
★The power cord, plug, switch, carbon brush and commutator must be checked regularly to avoid accidents during use.
★ The lubricating oil in the gearbox must be checked regularly and supplemented at any time. The bearing is filled with calcium-sodium grease (ZGN-1 or ZGN-2), and the gear is added with No. 3 calcium-based grease (ZG-3).
HZ-15 concrete electric core drilling machine is vertical downward direction, consisting of electric motor, gearbox, drill bit, column, base, lifting mechanism and so on.
The structure of the drilling rig, the single-phase series excitation motor is mounted on the reduction gear box, and the reduction gear box is fixed on the lifting mechanism, so that the reduction gear box can drive the drill bit under the main shaft to move up and down to achieve the purpose of drilling or coring.
The column has a rack that moves the gearbox up and down along the column, and its movement is achieved by manually rotating the feed handle.
