Magnetic drill

The development of magnetic drills is an urgent need for people to practice magnetic drills in the field. First of all, people want to punch and tap precisely like indoor machine tools when working in the field and at high altitude, but the general hand tools can't be precise. Secondly, when tapping the vertical steel structure and tapping the hole, it is necessary to consume a lot of physical force to fix the drill, or it is impossible to fix the punch at all. Work practice urgently requires a tool: it is very light weight, very suitable for field and aerial work, and the second is that it can be attached to the steel structure when it starts drilling and tapping, and no one needs to fix it. It is a magnetic drill--a metalworking tool that is precisely drilled, tapped, and reamed on steel structures.

definition

A simple and popular definition of a magnetic drill is a drilling rig that is affixed to a steel structure.

Scientific definition: The magnetic drill is mainly divided into two parts. The first part is the drilling part, which mainly drills or taps the steel structure by the high-speed running drill bit; the second part is the adsorption steel structure part, and the magnetic drill base part generates the magnetic field through the changing current after being energized, firmly Adsorbed on the steel structure to ensure that the magnetic drill does not move.

Magnetic drill other name

Magnetic drill is also called magnetic drill, iron drill, magnetic drill, punch, steel drill, iron drill, magnetic drill, portable magnet drill, magnetic drill, electric drill, drill and attack machine.

use

Suitable for steel structure, shipbuilding, equipment manufacturing, equipment installation, bridge engineering, wind power generation, oil rig, power construction, railway manufacturing and other fields.

species

Magnetic drills have different uses, which are different functions by linking different drill bits. The types of magnetic drill link drills are:

1, twist drill

2, core drill

3, countersunk bit

4, tapping machine

5, tapping machine

6, the reaming machine

The magnetic drill is divided into:

1, horizontal magnetic drill

2, vertical magnetic drill

Because the magnetic drill needs to be easy to carry in order to adapt to the field and aerial work, the most important features are light, so the horizontal magnetic drill customers do not use much. The most popular customers are vertical magnetic drills, vertical magnetic drills. Ten kilograms, with handles, the user can only go to the wild or work at heights by grasping the handle, which is very convenient, which is why it is called a portable magnetic drill. Because horizontal magnetic drills are used very little, it is generally said that magnetic drills are vertical magnetic drills, that is, vertical magnetic drills are referred to as magnetic drills.

Vertical magnetic drill classification and model

The vertical magnetic drill is mainly divided by the drill bit it uses, which is the model we often say. The maximum drilling of the core drill bit that it carries is the model of the magnetic drill.

The magnetic drill can be tapped, infinitely variable, torque protected and can utilize the adsorption force of the magnetic seat to drill from different angles. When used in conjunction with the core drill, the effect is better; at the same time, the problem of clearing the waste residue in the pipeline is solved, and the overlapping drilling of the steel plate can also achieve satisfactory results, and the problem of drilling stainless steel pipes and stainless steel of a certain thickness can also be solved.

Magnetic drill working principle

The magnetic drill is a movable high-efficiency tool that uses the electromagnetic principle to pass the magnetic base, adsorbs the rig frame and the rotary drilling mechanism on the surface of the steel workpiece, and performs the drilling process. The magnetic drill is the two main parts.

The first part: the magnetic seat, as shown in the bottom of the black rectangular parallelepiped part, its function is that after the energization, the magnetic drill generates electromagnetic force perpendicular to the bottom of the magnetic seat by electromagnetic effect, so that it is firmly adsorbed on the steel plate or structural parts. On the surface, it acts as a fixed machine. The stronger the magnetic attraction, the more stable the body of the magnetic drill while working, and the higher the precision of the drilling.

Part II: Drilling, which is divided into two parts:

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

2. It is the moving part. The motor start switch is turned on. The rotor in the machine motor rotates at a high speed. The drive shaft rotates through the transmission gear set to drive the drill bit to rotate. The drill hole is drilled through the drill bit at the part where drilling is required. Compared with the flame cutting hole, etc., the hole drilled by the magnetic seat has high precision, belongs to physical cutting, does not produce chemical reaction, and does not deform the material.

Key part

First, the core unit of the magnetic drill - motor

Second, the core unit of the magnetic drill - magnetic seat

The technology of the magnetic seat is particularly important. The magnetic drill with good quality is small, the sealing is good, the electric leakage is not easy, and the suction is large.

Third, the core unit of the magnetic drill - guide

In the field work, the construction environment, the material of the drilled hole, the brand of the drill used are different, the proficiency of the workers is different, the guide rail has a slight problem, and the precision of the drilled hole is not guaranteed, especially In the high precision requirement with high precision and small error, another index of the core of the magnetic drill is selected. This is the guide rail. When selecting the magnetic drill, you can hold the rack with one hand and shake the motor with one hand to see the shaking. The amplitude of the guide rail is not large, the guide rail with a small amplitude has better rigor, and the precision of the drilled hole is naturally high.

Fourth, the weight and overall design of the magnetic drill:

The overall design of the magnetic drill should be safe and convenient to operate, and it must conform to the ergonomic design. The domestic magnetic drill body cast iron is relatively heavy.

Installation-maintenance-repair

Magnetic drill installation maintenance and repair is mainly divided into two parts

The magnetic drill has developed rapidly, and the level of intelligence will be higher and higher. The controller must understand its installation, maintenance and repair.

A magnetic drill is installed and maintained.

The maintenance of the magnetic drill is a part that every customer must master. The magnetic drill does not pay attention to the maintenance, which will seriously affect the life of the magnetic drill and the accuracy of the drilling. Firstly, the installation of the magnetic drill bit is reduced.

1. Install the drill bit: When installing the drill bit and the drill head with the keyless converter, be sure to ensure that the drill bit is properly installed. Use the left hand to screw the quick change drill head counterclockwise to the end, and the right hand will vertically align the drill bit. The hole of the drill head is lifted up to the end, then the right hand gently rotates the drill bit until it hears a "click" to prove that the drill bit has been properly installed; if the drill bit needs to be removed, the quick change drill head is turned with the left hand. Screw it counterclockwise to the end and pull the drill bit vertically downwards with your right hand.

2. Inlet tightening adjustment: After using for a period of time, if it is found that the infeed stroke of the drill is not directly controlled by the handle, please open the iron cover and use the Allen key to tighten the hexagonal nut of the handle.

3. Overload: If the overload of the machine lasts for more than 10-16 seconds, the machine will automatically shut down. At this time, the motor switch can be turned off first, and the motor switch can be re-opened to resume normal operation. Similarly, if the power is interrupted during the use of the machine, turn off the motor switch after the call and re-open the motor switch to resume normal operation.

4. Infeed: Please slow down the speed when drilling the hole. After the drill is completely eaten, the feed speed will be increased. It is best not to turn off the motor during the drilling process. If the drill bit is blocked in the hole, turn off the motor and slowly unscrew the drill with a wrench.

5. Use of coolant: When drilling in a plane, use coolant to cool the drill bit. Do not use any coolant when absorbing the top or side holes to prevent the coolant from flowing into the hollow drill to cause a short circuit.

Maintenance of two magnetic drills.

The development of magnetic drill can be seen that the magnetic drill is required to be precise. Our ordinary operators should understand his basic principle, but the magnetic drill repair is best for professional disassembly and assembly maintenance. On the one hand, the magnetic drill generates high internal power. Voltage and high magnetic drill, non-professionals may be life-threatening; the second aspect of magnetic drills with high-precision drilling, non-professional disassembly and assembly may affect its accuracy.

Note: Be sure to turn off the switch and unplug the power cord before checking and maintenance.

1. The magnetic drill should be stored in an environment that is dry, clean, free from corrosive gases and inaccessible to children.

2. When disassembling the magnetic drill, each component should be stored. When assembling, the components should be placed according to the original position, and should not be missed or misplaced.

3. Magnetic drill transmission parts should be injected into the lubricating oil frequently and kept clean.

4, the magnetic drill should be regularly checked and maintained, must check whether the power line, plug, switch is good, whether the consumables (carbon brush) is sufficient, whether the insulation resistance is normal, and whether the transmission parts are damaged.
