(It is especially suitable for the forming of sheet thickness of 0.5~1.5mm. The width of the workpiece is adjustable. The adjustment range is 600-1500mm, which is suitable for professional production. Besides, we can add clips at two sides of the machine according to customers' requirements. The rollers are bearing steel. Lifetime is much longer than single TDF flange machine.)

Duplex TDF Flange Forming Machine Features

Duplex TDF flange forming machine completes TDF flange forming at both ends of the air pipe at one time, and the moving end guide rail adopts high precision.

Linear guides with high reliability and high load capacity make it easy to move and save labor. When the duct flange is formed, It can be used not only alone but also with the use of large air duct production lines. Compared with single TDF flange forming machines, it has high processing efficiency. The forming is stable and perfect, and can form a powerful processing capability.

ISUTAMI KBA-L long linear bearing , also known as KBA-L extended linear bearing unit, KBA-L extended linear slide unit or KBA-L extended linear case housing (unit), is a suitable series for European market. L is an abbreviation for Long. This model consists of a long type aluminum housing with 4 fixing holes as well as two KB standard linear bearings. There is an oil hole on the unit side and one circlip on each end in the proper position. There are also two rubber seals (UU) at both ends of the linear bearing to keep back debris or ball bearing contamination. The aluminum casing is applied because it is small and lightweight, this kind of material has strong corrosion resistance.

KBA-L Linear Bearing Pillow Block Features

The KBA-L long linear bearing pillow block housing is a closed, double-length European metric version. The two KB standard linear bearings are mounted in the housing and arranged in a straight line in the aluminum casing. Advantages of the bearing bushing include less tilt or friction, less wear over time, and better machining results.

If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this long aluminum bearing housing with KB standard linear bearings. Aluminum housing size range: length (L) ranges 58-230mm (matching KB standard linear bearing length (L) ranges 25-100mm); width (W) ranges 34-122mm; height (F) ranges 22-102mm. The minimum combined size of the specification KBA8L is 58*34*22mm, and the largest combined specification KBA50L is 230*122*102mm. These data are basically the same as the SMA-L extended type linear bearing pillow block, except that the KBA-L series has no diameter of 12mm and 35mm. The aluminum housing has four CNC drilled holes, threaded holes and countersunk holes of the same size M4-M10, which can be easily and safely mounted to almost any linear motion system.

A typical CNC system consists of a linear shaft of matching diameter, ranging from 8 to 60 mm in diameter, mounted on both ends of the shaft by two end supports, and the housing of the extended linear bearing runs straight along the shaft. Most CNC machines and 3D printers have two such components mounted side-by-side, using a housing as a stand to support the mobile platform. This is a long unit able to be mounted from above or below, making it easy to incorporate into the intended system. Positioning and precision enhancements are facilitated with one of the side aspects serving as datum face. The extruded aluminum case has undergone sufficient post-extrusion heat treatment to create a compact, lightweight and precision item.

As one of the most professional agricultural bearings suppliers, ISUTAMI is committed to providing customers with the best possible quality bearing products at the most reasonable price. If you want to know more details or want a quotation, just feel free to contact us!

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 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. We are one of the most professional flange machine manufacturers in China. Comifo tdf 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.

COMIFO Group specializes in air duct machine manufacturing, contracting and selling HVAC air conditioning equipments, HVAC machinery, valve and actuators,air duct machine,ductwork machine. RFQ today!

WELDING NECK RISE FACE FLANGE（WNRF）

Stainless steel weld neck flange is popularly used in excessive stress applications, with their capability to provide assisting power along with stress distribution. Weld neck flanges are circumferentially welded at the neck where the integrity of the butt welded location can be without problems examined by means of radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inner the pipeline. The weld neck is consequently durable in fundamental applications.

WHAT'S THE DIFFERENCE AMONG WELD NECK FLANGES, SOCKET WELD FLANGES, SLIP ON FLANGES?

Weld neck flanges, slip on flanges, socket weld flanges have different production standards, different applicable occasions. In addition, weld neck flange is the interface end pipe diameter and wall thickness is the same as the pipe to be welded.

Slip on flange is the joint being processed to a concave table a little larger than the pipe outside diameter, pipe inserted in the inside for welding. Weld neck flange has better welding performance and less corrosion.

Slip on flanges are generally used for low and medium pressure pipelines, weld neck flanges are used for connection of middle and high pressure pipelines, generally at least pn2.5mpa. Weld neck flanges are used to reduce stress concentration.

Features of various forged flanges:

Socket welding flange is suitable for connecting pipe with small diameter, high pressure and high temperature.

Slip on flange is the same with weld neck flange, has a groove cut in the lug and the pipe inserted into it for welding.

Socket weld flange has no boss, directly cut a groove in the flange body, just like a hole in the blind flange, and then cut a groove.

Slip on flange is slightly better than socket weld flange in performance.

Mainly for injection molding, the cavity pressure should be considered as small as possible when designing the runner and the parting surface. Since the BMC material cannot be decomposed, we are the first to use the materialless handle structure in China. Vacuuming structure, the mold temperature balance is consistent. The appearance and strength of the product are guaranteed.

High insulation, high temperature resistance and high strength. The flange molding has a high degree of standardization, reasonable flow channel design, small cavity pressure, balanced temperature, no handle, and low power consumption.
