Abstract
The utility model relates to a rotary cutter for T type tube hole flanging, comprising a forming cutter head and a positioning rod; the forming cutter head is a hemipyramid type structure, the joint between the forming cutter head and the positioning rod is a circular arc transition. The cutter head of the utility model is a hemipyramid type structure, and the joint between the forming cutter head and the positioning rod is a circular arc transition; in the process of the rotary flanging, each point of the hole wall can be guaranteed to have even and consistent force, thus the evenness of the flanging hole wall is guaranteed; the positioning rod in the middle part of the cutter can make the boring machine to center and position renewedly for the bottom hole. The utility model has the advantages of simple structure, low invested cost, small labor intensity and high production efficiency; and can fully satisfy the production requirements. The components and the tube blank that are formed by the utility model do not deform, and the flanging hole wall is smooth and even without crimple; which can meet the technical requirements of the product. The utility model is applicable to various kinds of metal pipes that need outer flanging; has good economic and social value; and is easy to be popularized and applied.
Description
Technical field
The utility model relates to a kind of small-bore T type pipe hole flanging utensil, relates in particular to a kind of T type pipe hole flanging rotary cutter.
Technical background
The idle call copper pipe, its external diameter 12mm, wall thickness 0.5mm, hole flanging outside processing on copper pipe according to the application target needs, require hole flanging after pipe do not have distortion, the hole flanging wall is smooth, no wrinkling, because the diameter of copper pipe is less, be subjected to the restriction of interior space dimension usually, can not design the used forming part of hole flanging, therefore adopting conventional cold punching die to carry out hole flanging is impossible realize.Also utilize Hubbing method that pre-punched hole is forced drawing in addition, force the pre-punched hole wall outwards to carry out flange and moulding, the part pipe that this kind method molds is yielding, and the flange hole wall is wrinkling, and inhomogeneous; Production efficiency is lower simultaneously, can not satisfy the requirement of production.
The utility model content
The purpose of this utility model is to provide a kind of T type pipe hole flanging rotary cutter, with guaranteeing the indeformable while of pipe, enhances productivity greatly.
To achieve these goals, the technical solution of the utility model is to have adopted a kind of T type pipe hole flanging rotary cutter, comprises moulding cutter head and backstay, and the moulding cutter head is the half-cone structure, and the junction of moulding cutter head and backstay is a round-corner transition.
The cone angle of described moulding cutter head is 45 °-50 °.
The cone angle of described moulding cutter head is preferably 45 °.
Rotary cutter of the present utility model comprises moulding cutter head and backstay, the shaping cutter head is the half-cone structure, and with the junction of backstay be round-corner transition, in the rotating flanging process, guaranteed that the hole wall each point can have the stressed of uniformity, thereby guarantee the uniformity of flange hole wall, the backstay that the cutter middle part is provided with makes boring machine carry out the centering location to bottom outlet again.The utility model is simple in structure, and is easy to use, and input cost is low, and labour intensity is little, and the production efficiency height can meet the needs of production fully.The part pipe that adopts cutter of the present utility model to mold is indeformable, and the flange hole wall is smooth no wrinkling, evenly, meet the product technology requirement, go for the metal pipe type element of the outer hole flanging of various needs, have good economic worth and social value, be easy to apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, T type pipe hole flanging rotary cutter of the present utility model comprises moulding cutter head 1 and backstay 2, and moulding cutter head 1 is the half-cone structure, and moulding cutter head 1 is a round-corner transition with the junction of backstay 2, and the cone angle of moulding cutter head is 45 °.
During use, hole flanging can adopt rotary forming method to finish, it does the straight-line feed motion by rotary cutter with certain velocity radial, and bottom outlet is reorientated correction by the backstay at rotary cutter middle part, guarantee that the boring machine center that aligns tangentially moves in a circle to finish this hole flanging moulding when rotating flanging.
It should be noted last that: above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
