The working principle and classification of imported magnetic drill

Imported magnetic drills are also called magnetic drills and magnet drills. After the power is turned on, the current at the bottom of the magnetic drill will generate a magnetic field, which is adsorbed on the steel structure, and then the motor of the magnetic drill runs at high speed to drive the drill bit to achieve drilling of the steel structure. . The magnetic drill is mainly divided into two parts. The first part is the drilling part, which is drilling or tapping the steel structure through the high-speed drill bit; the second part is the adsorbing steel structure part, after the magnetic drill base part is energized, the changing current is A magnetic field is generated, which can be firmly adsorbed on the steel structure to ensure that the imported magnetic drill does not move.

 

　　 Working principle of imported magnetic drill

 

Magnetic drill is a movable high-efficiency tool that uses the electromagnetic principle to attract the drilling machine frame and the rotary drilling mechanism to the surface of the steel workpiece through the magnetic seat. The magnetic drilling is the main two parts.

The first part: the magnetic base, its function is that after energization, the magnetic drill generates a magnetic attraction force of thousands of kilograms perpendicular to the bottom of the magnetic base through the electromagnetic effect, so that it is firmly adsorbed on the processing surface of the steel plate or structural parts, and plays a role in fixing the machine Function, the stronger the magnetic attraction, the more stable the body of the magnetic drill when working, and the higher the accuracy of drilling.

Part 2: Drilling. Drilling is divided into two parts:

1. It is a fixed part, which is fixed when drilling, the main function is to control the motor, such as the switch speed control gear and so on.

2. The moving part is the leftmost part as shown in the figure below, including the upper left black motor, the middle gray bracket on the left, and the lower left drill head. The entire moving part is manually rotated by the black Samsung frame to achieve up and down movement, so that the drill head is connected to the steel structure. Turn on the motor start switch, the rotor in the machine motor rotates at a high speed, and the drive shaft rotates through the transmission gear set, which drives the drill bit to rotate, and the drill bit is used to cut and drill the hole where it needs to be drilled. Compared with flame cutting, etc., the holes drilled by the magnetic base drill are of high precision and belong to physical cutting, which will not produce chemical reactions and will not deform the material.

 

　　 Classification of magnetic drill

 

1. Horizontal magnetic drill

In order to adapt to the field and high-altitude operations, the magnetic drill needs to be easy to carry, and the most important feature is lightness, so horizontal magnetic drill customers do not use much.

2. Vertical magnetic drill

The most commonly used are vertical magnetic drills, or magnetic seat drills, iron suction drills, steel plate drills, etc. Vertical magnetic drills are generally about ten kilograms, and some magnetic drills have developed to twenty kilograms, with handles. It is very convenient for users to work in the field or at height only by holding the handle and lifting it. This is why it is called a portable magnetic drill --- this is also the inevitable direction of the development of magnetic drills. Because horizontal magnetic drills are rarely used, the general situation when it comes to magnetic drills refers to vertical magnetic drills, which means that vertical magnetic drills are simply referred to as magnetic drills.

The above content is to introduce to friends the relevant knowledge about the working principle and classification of imported magnetic drills. With the rapid development of magnetic drill technology, the level of intelligence will become higher and higher, and the operator must understand its installation, maintenance and repair. The maintenance of the magnetic drill is a part that every user must master. If you do not pay attention to its maintenance, it will seriously affect the service life of the magnetic drill and the accuracy of drilling.

Bushing Cover For Electrical Connections is an insulation protection material for wire connection, in particular to an Insulation Protection Cover for wire connection that can provide insulation protection to wire connection parts. After the wires are connected, they need to be insulated and protected at the connection part. The usually used insulation protection material is power Insulation Tape, but in the actual use of power, sometimes due to the excessive voltage load of the wire, improper construction of the insulation protection material, and environmental issues. For this reason, the phenomenon of voltage breakdown of the insulating protective layer formed by the power insulating tape is often generated at the connection, which brings various safety hazards to people in daily life.

The purpose of the utility model is to provide an improved insulation protection cover for the wire connection, which can effectively prevent the phenomenon of voltage breakdown on the insulation protection layer of the wire connection during the use of electric power.
