Abstract
The utility model relates to a simple flanging device. A spherical surface is arranged at the left end part of a round bar and is connected with a cylindrical surface tangent to the spherical surface, and one side of the cylindrical surface is connected with a step on the round bar via a smooth curve. The utility model has simple structure, reasonable design, easy processing, low cost, and convenient operation.
Description
Technical field
The utility model relates to a kind of flange device.
Background technology
At present, in field of machining, the aperture of metal sheet turned over all over general adopt more on punch press, use special drawing die to carry out, or adopt manual drift to process, thereby low precision.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, easy to operate simple and easy flange device.
In order to achieve the above object, the technical solution adopted in the utility model is: be provided with sphere at round bar left end position and link to each other with its tangent face of cylinder, the face of cylinder one side is connected by the step that is provided with on smoothed curve and the round bar.
The utility model has the advantages that:
Simple in structure, reasonable in design, easily processing, with low cost, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is provided with sphere 1 at round bar 3 left end positions and links to each other with its tangent face of cylinder, and the face of cylinder one side is connected by the step 2 that is provided with on smoothed curve and the round bar 3.
The utility model is applicable to mouth of pipe flange behind the heat exchanger replace tubes, purpose is to make the mouth of pipe and tube sheet rounding off, guarantees that the pipe end face is clean and tidy, and pipe inner fluid resistance small flow is unimpeded, the left front end sphere face of cylinder external diameter tangent with it plays guiding function less than ips.Circular arc is a working face, and face of cylinder external diameter and the ips tangent with its left side are identical, play the radial location effect, guarantee flange circumference symmetry.Middle part cylindrical outer surface hatching knurling is conveniently held, and prevents to skid.The flange device is inserted in the caliber, knock the right side, can finish flange with hand hammer.
Claims (1)
1. a simple and easy flange device comprises round bar, it is characterized in that: be provided with sphere (1) at round bar (3) left end position and link to each other with its tangent face of cylinder, the face of cylinder one side goes up the step (2) that is provided with by smoothed curve and round bar (3) and is connected.
