Depending on the particular bending process used, the physical and mechanical properties of the starting material may be altered, but the ultimate goal of building an industrial device for transporting gas and liquid remains the same regardless of the technique employed. Bending is one of the most common of these processes, and it can be performed manually or by computer-controlled machines through either hot or cold forming methods. The disadvantage of this solution is that it can only be used for straight clamps, or on straight parts with shaped clamps using insert.After a tube or pipe has been fabricated, it usually has to undergo post-fabrication treatments in order to be formed into a usable product. The coarseness levels depend on the diameter of the tubes, from 30mm to 140 mm. We have three levels of coarseness: 12, 16 or 20-teeth per inch.

It does leave small marks on the pipe, but it also allows for the clamp length to be significantly reduced. Typically we would have 12, 16, 20 or 25 teeth per inch. It is set by the number of teeth per inch. The coarseness of the serration is chosen for the diameter of the tube. The main advantage of serration is that it allows us to significantly reduce the clamp length. This surface treatment is a machined serrated surface of the groove. This has a positive effect on the gripping surface of the and allows us to shorten the length of the clamp. That's why we recommend producing the diameter of the groove at the nominal diameter of the tube. This allows us to achieve a greater roughness and also reduce the diameter of the clamp by 0.1mm to 0.2 mm. The advantage of grit blasted clamps are that they do not lower the quality of the outer surface of the tubes after gripping.Īnother way we can treat the surface of the groove is with a carbide-based electric arc spray. Although we do not need to extend the clamps, we cannot shorten them either. Compared to the smooth surface, this method does not particularly affect the length of the clamps. This treatment is a gentle roughing of the functional surface of the clamp. This option is utilized in the furniture fabrication industry. The disadvantage of this surface is that it requires the use of long clamps so that there are no markings on the pipe from gripping. This variant is used in applications where it is necessary to take care of the visual quality of the surface of tube. The least useful, but sometimes necessary, is a groove with no surface treatment. The surface of the clamp has a significant impact on the functionality of the tools. The grip length of the bend die is dependent on the parameters of the tube and usually has a special surface treatment. It is often made separately and attached to the bend die. The gripping section grips the tube during the bend. Flange dies can be made with spool, one piece or horseshoe dies on top. This is useful for very small CLRs where the toolpost will not fit through.

A Full Platform has additional support around both sides of the bend die.įlange style dies mount directly to the bend head using bolts instead of having a toolpost and nut. Platform Bend Dies require additional material around the bend die itself to support it on the machine. A Partial Platform only has additional support on one side of the bend die. Similar to the Spool Bend Die mentioned above, One Piece Bend Dies are also incredibly common throughout the industry. One Piece Bend Dies are solid dies with a non-removable grip. These parameters then have a major impact on the size and shape of the bend die. The size of the groove will depend upon the outside diameter (OD) and the center line radius (CLR) the maximum degree of bend (DOB). The die is usually fixed using a key.ĭifferent types of Bend Die include: Spool, One Piece, Partial Platform, Full Platform, Flange. It is also possible to fix it directly to the machine using flanges.

The bend dies are most commonly bolted down. The size of the groove will depend upon the outside diameter (OD), the center line radius (CLR) and the maximum degree of bend (DOB). These parameters have a major impact on the size and shape of the bend die. The choice of Bend Die depends on the parameters of the bent tube (OD, CLR, DBB, DOB) and on the bending machine. The Bend Die is a tool, a mold, which allows tubes to be bent around it and defines the results shape of the bent tubes.
