Abstract
The utility model relates to a metal pipe bending technique, in particular to a crease-shedding die set for cold bending, which comprises a wheel die, a wheel die abaculus, and a crease-shedding die; wherein, arc ring grooves are installed around the sides of the wheel die, the front end of the crease-shedding die is provided with arc bulges matching with the ring groove. The utility model employs the project in order to effectively fill the gaps between the pipe wall and the wheel die in bending. In this way, the pipe wall becomes light, the inner wall with small radius bending is prevented from creasing, and the circumflexion turns to be more precise.
Description
Technical field
The utility model relates to metal tube pipe bending technique field, the crease-resistant module of using when relating in particular to a kind of pipe fitting cold bend(ing).
Background technology
Because it is energy-conservation, attractive in appearance, compact conformation etc. that industrial expansion requires.Tube components to industrial equipment, equipment etc. just requires to adopt thin-walled, minor radius bending as far as possible like this.Metal tube is a hollow object, and when pipe fitting was bent, wrinkle or section deformation appearred in sweep suffered stress complexity easily.
Common bending machine is in the bending pipes process, and the tube wall of elbow inside part is easy to form fold, and serious also can crack or break.This be because tubing in BENDING PROCESS, the wall compression of bend pipe inboard contracts, if between tube wall and wheel mould, have the gap, in the production plastic deformation, can produce the fold phenomenon so, this phenomenon mainly appears at the elbow rear portion, because in the bending pipes process, the constraint of mould is not taken turns at the elbow rear portion.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of in the bending pipes process, can effectively fill up the crease-resistant module in space between tube wall and the wheel mould.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of crease-resistant module that is used on the bending machine, comprise the wheel mould, the wheel mould is inserted and crease-resistant die body, the described mould side of taking turns is circumferentially with the circular arc annular groove, described take turns mould insert be embedded in the wheel mould on, the wheel mould is inserted and is provided with circular arc straight trough A, circular arc straight trough A is tangent with the circular arc annular groove on the wheel mould, the inboard of described crease-resistant die body is provided with circular arc straight trough B, circular arc straight trough A on circular arc straight trough B inserts with the wheel mould is complementary, described crease-resistant die body front end is provided with and takes turns the circular arc convex piece that the circular arc annular groove on the mould is complementary, and the radius of circular arc convex piece equates with the radius of circular arc annular groove.
As preferably, described circular arc annular groove is semicircle annular groove, and described circular arc straight trough A, circular arc straight trough B are semicircle straight trough, and described circular arc convex piece is semicircle convex piece.
As preferably, described the insert edge in the outside of mould of taking turns is tangent with the outer of wheel mould.
As preferably, the arc edge of described crease-resistant die body is complementary with the outer of wheel mould.
The utility model is owing to adopted above technical scheme, by on crease-resistant die body, adopting modern Computerized Numerical Control processing technology processing circular arc convex piece, its circular arc annular groove with the wheel mould is closely cooperated, satisfied of the circular arc annular groove tight requirement of pipe fitting curved interior fully with the wheel mould, make pipe fitting thin-walled, minor radius bending reach inboard wrinkle resistant, make crooked precision more accurate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of described crease-resistant die body.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
As Fig. 1, a kind of crease-resistant module that is used on the bending machine as shown in Figure 2, comprise wheel mould 1, the wheel mould inserts 2 and crease-resistant die body 3, be circumferentially with semicircle annular groove 4 in wheel mould 1 side, the diameter of semicircle annular groove 4 equates with the external diameter of required bending pipe fitting, the wheel mould insert 2 inlay be the wheel mould 1 on, the wheel mould is inserted and 2 is provided with semicircle straight trough A6, semicircle straight trough A6 is tangent with the semicircle annular groove 4 on the wheel mould 1, the insert edge 7 in 2 outsides of wheel mould is tangent with the outer 8 of wheel mould 1, the semicircle annular groove 4 of curved interior and wheel mould 1 and take turns the mould tight between 2 the semicircle straight trough A6 of inserting when making pipe fitting crooked.
Be provided with semicircle straight trough B9 in the inboard of crease-resistant die body 3, semicircle straight trough B9 and the semicircle straight trough A6 that the wheel mould is inserted on 2 are complementary, and its diameter equates with the external diameter of required bending pipe fitting.
Be provided with the semicircle convex piece 5 that is complementary with semicircle annular groove 4 at crease-resistant die body 3 front ends, the diameter of semicircle convex piece 5 and the equal diameters of semicircle annular groove 4, tight between the semicircle straight trough B9 of the semicircle annular groove 4 of curved interior and wheel mould 1 and crease-resistant die body 3 when making pipe fitting crooked.
Simultaneously, the arc edge 10 of crease-resistant die body 3 is complementary with the outer 8 of wheel mould 1.
