Abstract
The invention discloses an exhaust pipe bending machine and an application method thereof. When a rotating handle is pressed down, a connecting rod can slide by a certain distance in a trapezoidal groove, so that it is guaranteed that a roller base can be evenly stressed. A plurality of rollers increase the contact area of a guide groove and the bending position of an exhaust pipe, it is guaranteed that the bending position can be evenly stressed, hence, the phenomena that the exhaust pipe is broken up directly or cracks happen to the bending position can be reduced, and thus the rejection rate of the exhaust pipe can be lowered.
Description
Technical field
The present invention relates to a kind of pipe bender, specifically refer to a kind of blast pipe bender and using method thereof.
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 generally be parallel to ground backward, 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 the angle made new advances is discharged to method for designing according to existing tail gas exhaust pipe of motor vehicle road angle direction design and Principle of Mechanical Designing.
In the process of the discharge duct of high-power transport vehicle, the pipe bender on the market usually adopted is exhausted the bending of pipe, but pipe bender great majority are on the market angle of bend is 90 °, when using this type of pipe bender, and cannot one-shot forming.For meeting the process requirements of blast pipe, staff also needs to proofread the pipe fitting of bending, in check and correction process, because manual operation precision is lower, pipe fitting is easily caused directly to fracture, again or the bending part of pipe fitting there will be significantly depression or crack, and then cause blast pipe to be scrapped, and in operation, the time expended is long, waste of material is serious, also greatly increases the labour intensity of workman.
Summary of the invention
The object of the present invention is to provide a kind of blast pipe bender and using method thereof, the processing of easy to exhaust pipe, reduce artificial labour intensity, ensure blast pipe stability in use.
