Abstract
The utility model discloses a device for machining a pipe-shaped rivet flanging. The device comprises a cutter body, wherein one end of the cutter body is provided with a cutter head; the cuter head comprises a first blade body and a second blade body which are arranged in parallel, the first blade body is not longer than the second blade body and is connected with the second blade body in an arc manner, and a flanging groove is formed in the connecting part of the first and second blade bodies. The device for machining the pipe-shaped rivet flanging solves the problems that an existing machining mold is long in manufacture period and high in cost, and that a flanging is likely to crack and deform due to cold extrusion machining, and is simple in structure; the cutter head is easy to manufacture, and pipe-shaped rivets with different sizes can be machined by only changing the corresponding sizes of the cutter head, so that a mold with long manufacture period and high cost is not required, manpower and materials are saved, the machining efficiency is high, the operation and the use are convenient, the stability is good, the machining yield is high, and the machining quality of the pipe-shaped rivet flanging is greatly improved.
Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, is specifically related to a kind of be used to processing the device of pipe type rivet flange.
Background technology
Pipe type rivet is all generally that the end at straight tube is provided with the semicircle flange, and it is mainly used in the connection of non-bearing structure with securing member.The purposes of pipe type rivet is more, and its hollow cavity is generally used for crossline, is widely used in small-scale structure spare and the soft materials connections such as plastics or fiber such as electronic circuit board, electrical equipment, household electrical appliance, office appliance.
At present, pipe type rivet generally adopts the cold extrusion mode to process, and namely installation mold is processed on punch press.And in actual production due to the problem that die manufacturing cycle is long, expense is high, this processing mode is inapplicable for the pipe type rivet of the many specifications of small lot; During simultaneously due to punch forming, can't overcome the problem that stress is concentrated, in processing, easily cause rivet flange craze and transfiguration, be difficult to guarantee specification requirement.
The utility model content
It is a kind of be used to processing the device of pipe type rivet flange that the purpose of this utility model is to provide, and solved the problem that the existing processing mold manufacturing cycle is long, expense is high and the flange craze and transfiguration caused is processed in cold extrusion.
The technical scheme that the utility model adopts is: be used to processing the device of pipe type rivet flange, comprise cutter hub, one end of cutter hub is provided with cutter head, cutter head by the first sword body be arranged in parallel and the second sword body, formed, the length of the first sword body is not more than the second sword body, between the first sword body and the second sword body, be the circular arc connection, and junction forms the flange groove.
Characteristics of the present utility model also are,
The end of the first sword body and the second sword body is circular arc.
The degree of depth of flange groove is not less than the flange length of the pipe type rivet of processing, and the width of flange groove is not less than the flange width of the pipe type rivet of processing.
The beneficial effects of the utility model are: the utility model is for processing the device of pipe type rivet flange, simple in structure, the making of cutter head is easy, pipe type rivet for different size, only need to change the corresponding size of cutter head, processing be can complete, without re-using the mould that the manufacturing cycle is long, expense is high, manpower and material saved.And good stability, processed finished products rate are high, make crudy greatly improve.
The accompanying drawing explanation
Fig. 1 is the utility model be used to the structural representation of the device of processing the pipe type rivet flange;
Fig. 2 is that the utility model is be used to processing the method processing pipe type rivet turn-up process schematic diagram of pipe type rivet flange;
Fig. 3 is the structural representation of the pipe type rivet that processes.
In figure, 1. cutter hub, 2. cutter head, 3. flange groove, 4. pipe type rivet blank, 5. the first sword body, 6. the second sword body, 7. pipe type rivet, 701. flange.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Of the present utility model be used to processing the device of pipe type rivet flange, as shown in Figure 1, comprise cutter hub 1, one end of cutter hub 1 is provided with cutter head 2, cutter head 2 by the first sword body 5 be arranged in parallel and the second sword body 6, formed, the length of the first sword body 5 is not more than between the second sword body 6, the first sword bodies 5 and the second sword body 6 and is the circular arc connection, and junction forms flange groove 3.
The end of the first sword body 5 and the second sword body 6 is circular arc.
The degree of depth of flange groove 3 is not less than flange 701 length of the pipe type rivet 7 of processing, and the width of flange groove 3 is not less than flange 701 width of the pipe type rivet 7 of processing.
Add man-hour, pipe type rivet blank 4 is installed on the chuck of lathe, then cutter hub 1 is installed in the capstan head taper hole of lathe, and make cutter head 2 aim at the processed limit of tubulose rivet blank 1, as shown in Figure 2; Now start lathe, after cutter head 2 moves to pre-set position towards the direction of pipe type rivet blank 4, restart the capstan head taper hole, make the cutter head rotation, the effect that contacts spinning by cutter head 2 with pipe type rivet blank 4 makes pipe type rivet blank 4 complete the flange moulding.
The pipe type rivet 7 be processed into as shown in Figure 3.
By with upper type, of the present utility model be used to processing the device of pipe type rivet flange, solved the problem that the existing processing mold manufacturing cycle is long, expense is high and the flange craze and transfiguration caused is processed in cold extrusion.The utility model is for processing the device of pipe type rivet flange, and simple in structure, the making of cutter head is easy, for the pipe type rivet of different size, only need to change the corresponding size of cutter head, can complete processing, without re-using the mould that the manufacturing cycle is long, expense is high, manpower and material have been saved.Of the present utility model working (machining) efficiency is high, easy for operation be used to processing the method for pipe type rivet flange, and good stability, processed finished products rate are high, make crudy greatly improve.
