1. Construction and industry.
It is widely used in the reinforcement of building beams, panels, columns, walls, etc., and the installation of decoration, wall installation, brackets, railings, billboards, air-conditioning outdoor units, guide rails, satellite receiver elevators, and steel structure workshops.
2. Medical application.
(1) Dentistry:
In the early 20th century, a wall-mounted three-arm dental drill appeared with a speed of 4000r/min, and some even reached a speed of 10000r/min. The three-arm dental drill that we are still widely using is a derivative of it. thing.
(2) Otology:
Modern electric drills and air drills have greatly increased the speed and enhanced the cutting capacity. The use of fast cutting drills, diamond drills and irrigation-suction systems enables otologists to quickly complete accurate surgical anatomy and greatly shorten the operation time.
3. Marine flexible rod electric drill.
A new type of marine drilling equipment, mainly used for coring and sampling of seabed bottom layer, and exploring marine geology and minerals.
First, it was successfully developed by the French Institute of Petroleum (IFP). It was initially used to drill 300 meters and 500 meters of drilling on land, and later cooperated with the Soviet Union to drill oil wells as deep as 3,000 meters.
It was successfully tested at sea for the first time in 1965, and the drilling water depth reached 2,500 meters. ECSM marine flexible rod coring drill is to install flexible rod, electric drill, coring tube, drill bit and submersible pump on the same frame, lower it to the seabed with a wire rope, and use the cable to supply power from the ship surface and realize remote drilling. Drilling to a depth of 100 meters in 500 meters of water depth can take out 3.5 inches of core. The machine weighs about 10 tons.
Extended information
Electric drill products used in households (called DIY abroad) have low requirements for service life, work efficiency, and processing accuracy, and the number of products is large, accounting for about 70-80% of the total electric drill products; another 30-20% Electric drill products belong to professional tools, that is, products that are usually called "industrial power tools" in China.
The technical requirements are higher, including processing accuracy, reliability (such as a failure time, number of damages), service life, performance level (such as torque, coaxiality), etc. are higher than household products.
Double insulation technology provides a safe, reliable and advanced insulation structure to prevent electric shock accidents for the use of hand-held electric tools, which is the development trend of electric tool safety technology. Since the 1960s, my country's electric tool manufacturing industry has begun to study the application of double insulation in electric tools, and has trial-produced prototypes of electric drills and other products. In 1998, double-insulated electric tools accounted for more than 90% of the industry's annual output.
High-end drill chucks are mainly used in high-demand professional power tools, bench drills, etc. The demand for high-performance self-locking drill chucks and heavy-duty wrench drill chucks continues to increase. The high-performance self-locking drill chuck has the characteristics of high precision, high technology content, high added value and high benefit. It is mainly matched with impact drills above 850W and 24V DC impact drills in professional electric tools.
As the quality and performance of electric tools are improving, it is required to be able to reliably perform drilling operations under vibration and impact conditions, so the matching drill chuck is required to have a locking function, which can ensure that the tools such as drill bits held by the electric drill are not loose during use. take off. The global demand for self-locking drill chucks is expected to be about 19 million by 2010.
