FLANGE FORMING MACHINE

  

There are mainly two kinds of flange systems of duct connection. American standard and European standard, which is TDF flange recommended by SMACNA association and TTF/LT mate flange as well as improved GDF flange recommended by British Refrigeration Association. Comifo, as one of the professional flange machine manufacturers in China, providing machine ducting, knows flange structure very well, and quite familiar with the standards of duct pressure test and leakage test, including SMACNA, DW144/142, GB50243-97 standards. Comifo flange forming machine can satisfy different requirements in different markets.

 

Comifo flange machine adopts heavy duty underpan, arc welding frame, high grade motor, high precision bearing, thermal refined and grinded roll shafts. Its reliable transmission system is free of maintenance. The surface panels have been spray painted.

 

The air duct flange machine has independent hydraulic system and electrical control system, which has the advantages of small size, low energy consumption, high efficiency, no noise, etc. In addition, it is easy to install and unload, simple to operate, strong carrying capacity, long life, etc. The air duct flange machine must be put in a dry place, can't let the rain or other impurities into the machine, used for a period of time to add the lubricating oil, make the machine more convenient operation, want to be in a specific time to check the nut in the fuselage, because in the use process is too long will cause the nut loose, so be sure to check regularly, to ensure safety in production, in a certain time for cleaning, make the machine to enhance vitality. Because the duct flange machine needs to work all the time, if you pay attention to maintenance, the efficiency will be reduced and the life will be reduced. The followings are the precautions for the daily maintenance of the duct flange machine.

 

1. If it is found that there are irregular noises during operation, stop the machine immediately.

2. Test the motion after turning on the power to see if there is any jam.

3. Operate the machine according to the rules strictly.

4. Working cooperatively is required to each operator. Operation cannot start if the commands are not received.

HOW TO IMPROVE THE PRODUCTION EFFICIENCY OF FLANGE MACHINE





source: gzcomifo; Time: 06/09/2020 Clicks: 148

In today's competitive society, not only people need to improve their own competitiveness, but also machinery. If there is no better competitiveness, the same will be screened by the society.



The reason why flange machine is widely used is that it has very high production line power, so what is the reason why flange machine improves production power? There are the following points:

1. The automatic flange machine has high precision and rigidity. It can choose favorable processing quantity and high output power.

2. High machining precision and stable machining quality.

3. Flange machine is highly automatic and can reduce labor intensity.

4. When the machining parts are changed, only the NC program of the flange machine needs to be changed, which can save the production preparation time.

5. High quality requirements for operators and higher technical requirements for repairmen

WHAT ARE THE CHARACTERISTICS OF THE STRUCTURE OF THE SQUARE TUBE MACHINE?

The scope of application of mechanical equipment is very wide, according to different needs, square tube machine also has different characteristics. So what's the difference between welded square tube and seamless square tube? Let's follow gzcomifo to understand it.

1. Square tube is a hollow square section steel square tube, also known as steel cold-formed section. It is a section steel with square section shape and size, which is made of hot or cold rolled strip or coil as the blank by cold bending and then by high frequency welding. In addition to wall thickness thickening, the corner size and edge straightness of square tube can reach or even exceed the level of resistance welding cold formed square tube.

2. Seamless square tube is a kind of long steel with hollow section and no joints around. The square tube machine has hollow section and is widely used as the pipeline for conveying fluid. Mainly used in liquid transportation, hydraulic support, mechanical structure, medium and low pressure, high pressure boiler pipe, heat exchange pipe, gas, oil and other industries.

HOW TO JUDGE THE QUALITY OF THE SQUARE TUBE MACHINE



source: gzcomifo; Time: 06/23/2020 Clicks: 142

As we all know, the quality of square tube machine is very important in the process of using. Let's talk about the good and bad quality of the square tube machine.



1. The fake square tube machine is easy to fold. Folding is a variety of fold lines formed on the surface of square tube, and this kind of defect often runs through the longitudinal direction of the whole product. The reason for folding is that the fake and inferior manufacturers pursue high efficiency, the reduction is too large, the ears are produced, the folding occurs in the next rolling, the folded products will crack after bending, and the strength of the steel will be greatly reduced.



2. The appearance of the fake square tube machine is often pockmarked. Pockmarked surface is a kind of irregular uneven defect on the surface of steel due to the serious wear of rolling groove. Because the fake square tube manufacturers want to pursue profits, and often the rolling groove exceeds the standard, it is necessary to select the equipment with better quality than the pipe welding machine.



3. There are two reasons for scab on the surface of fake square tube:

(1) The material of the fake square tube is uneven, and there are many impurities.

(2) It is easy to stick steel because of the poor guide equipment of the fake factory.

WHAT FACTORS ARE RELATED TO THE MANUFACTURING ACCURACY OF THE SQUARE TUBE MACHINE?

Stainless steel pipe is a kind of hollow long round steel, which is mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical appearance and other industrial transportation pipes and mechanical structural components. In addition, in bending. With the same torsional strength and light weight, it is also widely used to make mechanical parts and engineering structures of the square tube machine. It is also used to produce all kinds of weapons, barrels, shells, etc.



1. Concentricity

The manufacturing process of seamless tube makes a hole punched in stainless steel billet at 2200 ° F. at this high temperature, tool steel becomes soft and spiral from the air after stamping and drawing. In this way, the wall thickness of the pipe is uneven and the degree of bias is high. Therefore, ASTM allows the wall thickness difference of seamless welded pipe to be larger than that of welded pipe. Seamed tubes are made of accurate cold-rolled sheets (4-5 feet in width per roll), the maximum wall thickness difference of these cold-rolled sheets is generally 0.002 inch, and the steel plate is cut into a width of π D, in which D is the outer diameter of the tube. The wall thickness of seamed pipe is very small, and the wall thickness of the whole circumference is very uniform.



2. Welding function

Generally, there are certain differences in the chemical composition of the square tube machine between the sewn tube and the seamless tube. The steel composition of seamless pipe is only the basic requirement of ASTM. The steel produced with welded pipe contains a kind of welding melt which is easy to transfer heat during the welding process, so that the whole weld is fully penetrated. The square tube machine without the above chemical composition, such as seamless tube, will have various unstable factors in the welding process, which is not easy to be welded firmly and not fully penetrated.
