Abstract
The invention discloses an inserted elbow pressing die, which comprises an upper die and a lower die, wherein an upper die cavity is formed in the upper die, and comprises an upper cavity surface and a vertical upper parting surface; a lower die cavity is formed in the lower die, and comprises a lower cavity surface and a lower parting surface; the lower cavity surface is connected to a part below the lower parting surface in a transition manner; the upper die is inserted into the lower die; the upper parting surface is attached to the lower parting surface; and a hollow cavity formed by folding the upper cavity surface and the lower cavity surface has an elbow shape. According to the inserted elbow pressing die, an inserted attachment mode is adopted; the parting surfaces are vertical; and when an elbow is thermally pressed, a compacted blank cannot be squeezed out of the range of the cavity, so that the trimming amount of the molded elbow product can be controlled effectively, and the molding quality of the elbow product is improved.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of plug-in type elbow pressing mold.
Background technology
In chemical industry and boiler industry,, generally adopt pattern tube reducing press-bending manufactured for angle of bend≤90 ° heavy caliber sharp turn head.This method is to adopt the pipe of external diameter than the big certain size of elbow external diameter, bends in a series of cradle-type patterns and the tube reducing bending forming in the heating back.Because old-fashioned elbow pattern adopts the cradle-type structure of two halves up and down.Die joint launches along the both sides back of elbow, and the elbow blank can form overlap at the mould die joint in the process of tube reducing compression, influenced the type quality of elbow.
Summary of the invention
The invention provides a kind of plug-in type elbow pressing mold; This elbow pressing mold adopts plug-in type to fit; It is vertical that die joint is; Elbow can guarantee can not squeeze out the die cavity scope when blank by compression when hot compacting, can effectively control the overlap amount of moulding palintrope head product, has improved the forming quality of elbow product.
In order to achieve the above object, the present invention realizes through following technical scheme:
A kind of plug-in type elbow pressing mold, this pressing mold comprises upper die and lower die, is characterized in, and described patrix is provided with model cavity, and the described model cavity of going up comprises upper impression face, vertical last die joint;
Described counterdie is provided with the counterdie die cavity, and described counterdie die cavity comprises lower impressions face, following die joint, and the transition of described lower mode cavity face is connected down the top of die joint;
Described patrix is inserted in the counterdie, and the said die joint of going up is fitted with following die joint each other; Said upper impression face and lower impressions are the elbow shape in the face of the cavity that closes formation.
Described upper impression face is connected with last die joint transition through first fillet, and described upper impression face is cambered surface.
Described lower impressions face is connected with following die joint transition through second fillet, and described lower impressions face is cambered surface.
The size at the said open-ended place of die joint down is than the big 10 ~ 15mm of size of following die joint and lower impressions face transition junction.
A kind of plug-in type elbow of the present invention pressing mold compared with prior art has the following advantages:
1, upper and lower mould adopts plug-in type to fit, and it is vertical that die joint is.Elbow can guarantee can not squeeze out the die cavity scope when blank by compression when hot compacting, can effectively control the overlap amount of moulding palintrope head product, effectively raises the forming quality of elbow product.
2, because die joint is that vertically upper and lower mould can adopt intrinsic die joint bonding structure to position, and need not other Design Orientation device.
3, the size at the open-ended place of die joint is than the big 10 ~ 15mm of size of following die joint and lower impressions face transition junction down, and the reaction force that produces in the time of can not suppressing owing to elbow causes upper and lower mould stuck, can conveniently carry out the demoulding.

The specific embodiment
Below in conjunction with accompanying drawing,, the present invention is done further elaboration through specifying a preferable specific embodiment.
Like Fig. 1, shown in Figure 2, a kind of plug-in type elbow pressing mold, this pressing mold comprises patrix 1, counterdie 2, and described patrix 1 is inserted in the counterdie 2.
Like Fig. 3, shown in Figure 4, described patrix 1 is provided with model cavity, and the described model cavity of going up comprises upper impression face 11, vertical last die joint 12; This upper impression face 11 is through the first fillet R
1Be connected with last die joint 12 transition, said upper impression face 11 is cambered surface.
Like Fig. 5, shown in Figure 6, described counterdie 2 is provided with the counterdie die cavity, and described counterdie die cavity comprises lower impressions face 21, following die joint 22, and described lower mode cavity face 21 is through the second fillet R
2Transition is connected down the below of die joint 22, and said lower impressions face 21 is cambered surface.The said die joint 12 of going up is fitted with following die joint 22 each other, and said upper impression face 11 is elbow shape (as shown in Figure 2) with the cavity that lower impressions face 21 is combined to form.The size M at said die joint 22 open-ended places down is than the size L big 10 ~ 15mm of following die joint 22 with lower impressions face 21 transition junctions.
Please cooperate referring to Fig. 2, Fig. 7, during The field of the present invention, elbow patrix 1, counterdie 2 are fixed on the last lower platform of forcing press behind the aligned position in advance.Elbow blank pipe after will heating before the compacting beginning is placed in the elbow counterdie 2 of Fig. 6 after flattening, and the long axis direction after the flattening is vertically placed.Patrix 1 is fixed on the upper mounting plate of forcing press, and under the effect of oil hydraulic cylinder, patrix 1 slowly is pressed into elbow blank pipe in the counterdie die cavity.Because the restriction of die joint 22 is limited in down in die joint 22 position ranges through the pipe blank after the extruding all the time down.After treating that patrix 1, counterdie 2 are fitted, be filled in the elbow pressing mold tool die cavity through the pipe blank after the extruding.With carrying on the press upper mounting plate, elbow patrix 1 is detached counterdie 2 at last, the elbow after will being shaped at last takes out, and pressing process is accomplished.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
