|General Knowledge on “Metal Tube Bending”|
Tube bending is a processby using bending mold and deforming equipments, is the umbrella term for metal forming processes used to permanently form pipes or tubing. One has to differentiate between form-bound and free form-bending procedures, as well as between heat supported and cold forming procedures.It is divided into cold simmer and hot push . No matter what kind of equipment or pipelines, bends are very important elements.They are widely used primarily for the oil, gas and transfusion.
Stretch tube bending is a process in which a tube is formed by a stretching force parallel to the tubes axis, and a simultaneous bending force acting to pull the tube over a form block. The block is fixed and the forces are applied to the ends of the tube.
Draw tube bending involves clamping the tube near its end to a rotating form block. A pressure pad is also used to hold the tube stock. As the form block rotates the tube is bent.
Compressiontube bending is a tube bending process that has some similarities to edge bending of sheet metal with a wiping die. The tube stock is held by force to a fixed form block. A wiper like die applies force bending the tube over the form block.
Noticed Method when metal tube bending:
1, pure bending, tube outer torque M effect under which the outer layer arm & a wall tensile stress the role of thinning the inner compressive stress. Thickening effect, force N1 and N2 so that the tube cross-section changes. Based on this factor, causing the main reason for the decline in the quality elbow RX and SX Therefore, GBJ235-82 in the RX value and volume thinning various pressure levels outside of the case made it clear that the purpose is to control the RX the value SX, thereby ensuring the quality.
2, the preceding article have mentioned, when you bend the outer material which is pulled, the position of the neutral axis lies medial compression and bending method is different, curved at the top (compression bending) working from the outer wall of the neutral axis is about 1 / 3, when the rotary bending (curved back) work from the outer wall of the neutral axis is 2/3. So thin-walled pipe bending, bending method using a spin beneficial.
3, precision curved tire is one of the factors affecting the quality of the elbow. We manufacture bent tire, except when the size requirements to control certain tolerance range, it also requires the user to select the appropriate bend when used in accordance with the bending diameter tires.
4, the pipe itself bendable performance and surface corrosion, may also affect the quality of the elbow. When the construction site, the operator should also understood to be materials processing pipelines, processing performance and productivity of surface corrosion to make judgments. 5, now available in R. (Bending radius / tube diameter) graph showing the relationship (as shown), in time for the user to select the relationship between the tube diameter and the wall thickness of the reference. This figure reflects the relative bending radius focused on the impact of the relative thickness of the elbow quality, according to the pipeline processing of acceptance: steel pipes for cold-formed, medium and low voltage for 4D, high pressure for 5D. So we bend tire designed for R = 4D (special case separately), so I plant the bender to select a relative wall thickness of the main purposes of SX-based, top of the figure for non-mandrel district, central figure as an ordinary area of the mandrel, the lower drawing is a special mandrel section. Due to the special design and manufacture of the mandrel are very difficult, the operation is not easy, it is generally not our plant supplier. Special circumstances can be agreed.
5, the molding process affect the lubricating quality of the bent tube:
Enterprises in the traditional production process elbow, elbow for better surface quality, it will take a lot of ways, including: the use of more advanced high-end bender, with a higher intensity of the mold, or the use of lubricating products approach. High-grade bender and strength of the mold, companies often require a very large capital investment to complete, only the use of the elbow lubrication products are relatively inexpensive and quick to achieve enterprise product quality requirements. But in the traditional production process: oil-based lubricant products to meet enterprise elbow elbow elbow production quality requirements, but difficult to clean and pollution of the environment is very outstanding performance of oil-based lubricants elbow out so companies must use more means to eliminate because the use of oil-based lubricants elbow impact on the quality of the final product, put in more effort and money. The arrival of IRMCO elbow grease that is water-based business-to-elbow to meet product quality requirements, and also avoid and minimize enterprise because the use of oil-based lubricant products increased elbow investment, fully optimize the production processes.
