Description

Technical Field

[0001] The utility model relates to the technical field of chamfering of ductile iron pipe fittings, in particular to a chamfering mechanism for ductile iron pipe fittings. Background Art

[0002] Ductile iron pipes are made by adding magnesium or rare earth magnesium combined with gold spheroidizers into molten iron before pouring to spheroidize graphite and reduce stress concentration, making the pipes have the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing.

[0003] Pipe chamfering is to process the end of the pipe to make it an oblique angle or a rounded corner to improve the connection performance and service life of the pipe. Generally speaking, there are two ways to chamfer pipe fittings, namely external chamfering and internal chamfering. Pipe chamfering can improve the connection performance of the pipe. At the same time, pipe chamfering can form a better seal between the end of the pipe and the connecting pipe, thereby preventing loose connections and air leakage.

[0004] However, in the prior art, in the chamfering process of pipe fittings, such as external round chamfering, pipe fittings have different thicknesses. When chamfering thicker pipe fittings, it is necessary to enlarge the chamfered slope to improve the subsequent use effect of the pipe fittings. However, the prior art does not solve this problem.

[0005] To this end, the present application proposes a ductile iron pipe chamfering mechanism. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a chamfering mechanism for ductile iron pipe fittings, which overcomes the deficiencies in the prior art and aims to solve the problems in the background technology; the main bevel gear is driven by a rotating rod, and the main bevel gear drives the slave bevel gear to rotate, and the slave bevel gear causes the threaded rod to rotate. At this time, the slider moves outside the threaded rod in a direction away from the slave bevel gear, causing the stop block to move to an appropriate position in the chamfering groove. As a result, the space of the chamfering groove can be changed by adjusting the position of the stop block according to the thickness of the pipe fitting in actual use. Therefore, when the pipe fitting is chamfered, an ideal chamfering bevel can be achieved, thereby improving the subsequent use effect of the pipe fitting, thereby expanding the use limit of the chamferer, being suitable for pipe fittings of various thicknesses, achieving different chamfering bevels, and greatly improving the practicality of the chamferer.
