CNC flame cutting machine lead in line problem 5

Nima: Go upstairs, since you say that the No. 2 mouth can be cut When you are cutting the board, you can cut it It doesn't matter if you cut into the line 70 board, you must cut from the edge of the board It is impossible to make a hole so 5mm is OK It's a waste After all, such a thick board The fire must be adjusted well I often cut the 70 board The gun must be adjusted vertically When cutting in, bake it with fire in the place where it is cut In the red, open high-pressure oxygen on the outside of the board Cut in at a slow speed Adjust to the right number of degrees when completely worn The board surface must be clean Otherwise, it is easy to break the fire It will be troublesome Where there is rust, it is best to use a grinder to grind it Cut thick plates comfortably A plate is cut for a day Just sit on the machine One shift is over Hehe I use a 70 plate for No. 4 cutting nozzle No pressure Oh Hehe If you don't know, it's better to use No. 5 or No. 6.

No. 3 cutting nozzle is enough for 70mm steel plate, and the blind hole introduction line should be at least 25cm or more, the oxygen pressure should be above, and the cutting speed should be about 350. It's no problem to do what I say, I've been doing this for 10 years.

With the No. 5 cutting nozzle The introduction line depends on the space at the introduction line of the part, and the introduction line is a little longer! Because the fire during the piercing is different from the fire for cutting, so when the hole is pierced, the strong and hot oxygen should be turned off. The lead line is as short as possible!

No. 2 nozzle is OK, the lead-in line is 10mm, pay attention to lifting when piercing, don't make too much iron slag, affect the life of the nozzle.

Let's punch the hole first, so it will save a little trouble.

There are usually two ways to compile the processing program of a CNC cutting machine, manual programming and automatic programming.

1. The general process of manual programming is: analysis of parts pattern - CNC process processing - mathematical processing - writing NC** - calibration and debugging NC program - first piece trial cutting - error analysis, boring, cumbersome, error-prone, and difficult to memorize the instruction syntax.

2. When automatic programming, AutoCAD2000 can directly generate CNC machining from the graphic entity that describes the outline of the part from the two-dimensional graphics, so as to avoid the complex memory of manual programming. Significantly improve the efficiency of programming and the quality of programming.

CNC flame cutting machine, cutting has a large thickness of carbon steel cutting capacity, cutting cost is low, but there is a large cutting deformation, cutting accuracy is not high, and the cutting speed is low, cutting preheating time, perforation time is long, it is difficult to adapt to the needs of fully automatic operation. Its application is mainly limited to carbon steel and large-thickness plate cutting, and will gradually be replaced by plasma cutting in medium and thin carbon steel plate cutting.

1. Check whether there is any leakage in each gas circuit and valve, and whether the gas safety device is effective.

2. Adjust the cut steel plate and keep it parallel to the track as much as possible; According to the thickness and material of the plate, select the appropriate cutting nozzle. Make the nozzle perpendicular to the plate.

3. Check the heating flame and the cutting oxygen jet, if the cutting nozzle is damaged, it should be replaced and cleaned in time. Clean the nozzle with a special tool.

4. The operator should pay attention to the fact that after cutting a workpiece, the torch should be lifted back to the original position, and then cut when it runs to the next station.

5. After work, the equipment should be returned to the support position and the air valve should be closed. The residual gas in the pipe should be exhausted and the power supply should be turned off.

Dear, hello, I am glad to answer for you, the programming introduction and operation method of the flame CNC cutting machine 1, the power of the preheating flame should increase with the increase of the thickness of the plate, the thicker the cutting piece, the greater the power of the preheating flame; 2. When cutting thicker steel plates, a slight carbonization flame should be used to avoid the collapse of the upper edge of the incision, and at the same time, the outer flame can be longer. 3. When using the diffusion type nozzle and the oxygen curtain nozzle to cut the steel plate with a thickness of less than 200mm, the flame power should be selected to be larger to accelerate the heating of the leading edge of the incut to the ignition point, so as to obtain a higher cutting speed. 4. When cutting steel with higher carbon content or more alloying elements, because they have a higher ignition point, the power of the preheating flame is greater.

5. When cutting the groove with a single cutting nozzle, the slag is blown to the outside of the incision, and the flame power should be increased in order to replenish energy. Feature analysis: CNC flame cutting machine will be the traditional flame cutting method and CNC automation technology combined, can be used for 6mm thickness of more than carbon plate and carbon plate cutting processing, considering the use of steel in the domestic market, CNC flame cutting still occupies a large market.

The cutting method of CNC flame cutting machine is different from the cutting method of CNC plasma cutting machine, flame cutting is a cutting method that uses a high temperature flame to heat a certain point on the surface of the steel plate to the ignition point, and fills it with high-pressure oxygen to make it burn to form a cut. Usually gas and oxygen are required for flame cutting, and there are three types of available gas for flames: coal gas, propane, and acetylene.

Among them, the calorific value of coal gas is the smallest, followed by propane, and acetylene is the largest. The higher the calorific value, the faster the cutting, and the faster the burning, the better the cutting effect. Flame cutting can only cut metals that are easy to oxidize, and flames with relatively high carbon content are difficult to cut.

The thickness of flame cutting is generally carbon steel above 6mm, although it can also be cut for plates below 6mm, but because the plate is thinner, because the flame cutting method is to use a high-temperature flame to heat a certain point on the surface of the steel plate to the ignition point, and fill it with high-pressure oxygen, so that it burns to form a cutting method. Therefore, when cutting the plate, it is easy to produce thermal deformation of the plate, and the cut plate cannot achieve good results. Generally, the flame CNC cutting machine can cut to 200mm, and then after special transformation, it can cut 350mm.

In terms of cutting speed, CNC flame cutting is many times faster than manual cutting. But it's a little slower than plasma cutting. Compare with a 20mm thick sheet.

The flame cutting speed is about 450mm min and the plasma cutting speed is about 1500mm min per minute. In terms of cutting effect, the verticality of flame cutting is better than that of plasma, the flame cutting surface is vertical, and the plasma cutting surface has a certain inclination. Operating Procedures:

1. Before work (1) check whether there is any leakage in each gas circuit and valve, and whether the gas safety device is effective. (2) Check whether the gas inlet pressure provided meets the specified requirements. (3) Check whether the power supply voltage provided meets the specified requirements.

2. Work 1. Adjust the steel plate to be cut and keep it parallel to the track as much as possible.

Hello, flame CNC cutting resistance without machine gun does not move: one: the connection line of the motor is not in good contact or virtual welding; Workaround:

Check and connect the wire with a multimeter: the connecting wire of the button is not in good contact or falls off; Solution: Check and connect the wires with a multimeter.

Three: the relay that adjusts the lifting is damaged; Solution: Replace the parts of the same specification and model for the failure of the CNC cutting machine is often unavoidable, so it is quite necessary to master a certain knowledge of the CNC cutting machine, in addition to the purchase of CNC and other sections of the Yuzi cutting machine should be recognized as a regular manufacturer, after-sales is a more important element.

Summary. Hello dear and happy to answer for you. The flame cutter has been in a cutting state after piercing There are several reasons why it does not walk:

1. Problems with the motor itself; 2. Communication problems between the system and the motor (this has to be repaired by professionals); 3. The installation accuracy of the equipment, the horizontality and verticality of the track.

The flame cutting machine keeps the cutting state all the time after piercing and does not walk.

Hello dear, I am happy to answer for you to unrent the rent. The flame cutting machine has been kept in a cutting state after perforation There are several reasons for not walking: 1. The problem of the motor itself; 2. Communication problems between the system and the motor (this has to be repaired by professional filial piety personnel); 3. The accuracy of equipment installation, the levelness and verticality of the track.

In this case, it may be that the rotor or the stove is broken, or there may be no carbon brush, and there is a possibility that the power cord is broken, and the solution is that if the rotor or stator is broken, change the rotor and stator, if the carbon brush is gone, argue and change the carbon brush, if the power cord is broken, change the power cord.
