Description
Technical field
The present invention relates to a kind of exhaust manifold bending tool, specifically refer to a kind of exhaust manifold processing device.
Background technology
The exhaust angle of automotive emission pipeline is the insoluble problem of specialized factory always.By inquiry, the angle direction of car and light weight domestic automobile exhaust pipeline is to be generally parallel to backward ground, and the angle of high-power transport vehicle and agri-vehicle discharge duct is folded to ground.From the angle of environmental protection, also do not specify that according to existing the angle direction design of tail gas exhaust pipe of motor vehicle road and Principle of Mechanical Designing the angle making new advances is discharged to method for designing.
In the process of the discharge duct of high-power transport vehicle, the pipe bender on the market conventionally adopting carries out the bending of blast pipe, and still, pipe bender great majority are on the market that angle of bend is 90 °, in the time using this type of pipe bender, and cannot one-shot forming.From industrial analysis, common bend pipe defect mainly contains following several form thus: circular arc place becomes that tube wall thickness is excessive outside flat serious (ellipse), circular arc, the outer lateral bending of circular arc splits, wrinkling and bending springback etc. inside circular arc.Along with the difference of elbow radius, mode and position that front four kinds of defects produce are different, and not necessarily occur simultaneously, and the elastic recoil of curved workpieces is inevitable.The existence of bend pipe defect can produce very large negative effect to the quality that bends pipe fitting.Pipe thickness attenuation, must reduce pipe fitting and bear the ability of interior pressure, affects its serviceability; The distortion of bending tubing section configuration, may cause that area of section reduces on the one hand, thereby increases the mobile resistance of fluid, also affects on the other hand the functional effect of pipe fitting in structure; Pipe material inner wall is wrinkling not only can weaken pipe intensity, and easily causes flow media speed inequality, produces eddy current and crooked position and gathers dirt, and impact bends the normal use of pipe fitting; Rebound phenomenon must make the angle of bend of tubing be greater than predetermined angular, thereby reduces bending process precision.For meeting the process requirements of blast pipe, staff also needs the pipe fitting of bending to proofread, in check and correction process, because manual operation precision is lower, easily cause pipe fitting directly to fracture, again or the bending part of pipe fitting there will be obvious depression or crack, and then cause blast pipe to be scrapped, and in operating process, the time of expending is long, waste of material is serious, has also greatly increased workman's labour intensity.
