Abstract
The utility model belongs to the field of machining, and particularly relates to an inverted-U-shaped sectional material variable angle forming die. The inverted-U-shaped sectional material variable angle forming die comprises a die base, a movable press block, a first press block, a second press block and a third press block, wherein the first press block, the second press block and the third press block are arranged from top to bottom. The die base comprises a bottom board and a fixing board, wherein the fixing board is of a symmetrical structure and a plurality of U-shaped grooves are formed in the two sides of the fixing board. When inverted-U-shaped parts are machined, only one set of general die needs to be manufactured, and inverted-U-shaped sectional materials serve as blanks. Through changes of the pressure and the suppressing time every time suppressing is carried out, different needed angles 'alpha' can be suppressed. Forming requirements of the inverted-U-shaped parts of various and different standards are met, working amount for machining the inverted-U-shaped parts is reduced greatly, the manufacturing cycle of products is shortened, production efficiency is improved, and production cost is reduced greatly.
Description
Technical field
The utility model belongs to field of machining, particularly relates to a kind of " Π " shape section bar variable-angle shaping mould.
Background technology
In airplane parts, there is a kind of part section shape to be " Π " shape, band angle " α " (as Fig. 2), the section shape of this part is consistent with " Π " shape section bar.This kind part is designed different angle " α " according to different use positions.For this reason, for this type of part of different angles size, method commonly used is " Π " shape part that the method for employing digital control processing becomes the plate milling special angle " α ".This method manufacturing process complexity, the cycle is long, cost is high, production efficiency is low.Be difficult to satisfy the research and production needs.
Summary of the invention
Goal of the invention: a kind of " Π " shape section bar variable-angle shaping mould, the part processing difficulty that solves the various angles of " Π " shape is big, and the cycle is long, the problem that production efficiency is low, cost is high.
Technical scheme: a kind of " Π " shape section bar variable-angle shaping mould, comprise die holder 1, briquetting 2 alive and top-down first briquetting 3, second briquetting 4 and the 3rd briquetting 5, described die holder 1 comprises that base plate 101 and both sides are provided with the fixed head 102 of the symmetrical structure of several U-shaped grooves, described briquetting alive 2 is made up of two block plates 201 and two axles 202, form " mouth " font frame, described three briquettings are formed by fixed head 301, eyelet bolt 302, straight pin 303 and band shoulder nut 304.
The U-shaped groove quantity that arranges on the described fixed head 102 be about each three.
Angle is worn in the upper end of the fixed head 301 on described second briquetting 4 and the 3rd briquetting 5.
Beneficial effect: when " Π " shape part processing, only need to make a cover universal mold, use " Π " shape section bar to be blank.Change the pressure size of each compacting and the length of press time during by compacting, just can suppress needed different angle " α ".Satisfy the demand of various different sizes " Π " shape forming parts, significantly reduce workload, the shortening product manufacturing cycle of " Π " shape part processing, enhance productivity, reduced production cost greatly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe in further detail, seen also Fig. 1 to Fig. 7.
As shown in Figure 1, be the reset condition schematic diagram of section bar, this section bar need be processed into band angle " α " (as shown in Figure 2).
In order to process above-mentioned section bar, a kind of " Π " shape section bar variable-angle shaping mould is provided, comprise die holder 1, briquetting 2 alive and top-down first briquetting 3, second briquetting 4 and the 3rd briquetting 5, described die holder 1 comprises that base plate 101 and both sides are provided with the fixed head 102 of the symmetrical structure of several U-shaped grooves, described briquetting alive 2 is made up of two block plates 201 and two axles 202, form " mouth " font frame, described three briquettings are formed by fixed head 301, eyelet bolt 302, straight pin 303 and band shoulder nut 304.
The U-shaped groove quantity that arranges on the described fixed head 102 be about each three.
Angle is worn in the upper end of the fixed head 301 on described second briquetting 4 and the 3rd briquetting 5.
During use, by straight pin 303 fixed head 301 and eyelet bolt 302 are assembled together, fixed head two ends symmetry is shaped on U-lag and circular hole.This circular hole is used for installing straight pin 303 and guarantees that H7/m6 cooperate, the circle hole sleeve of eyelet bolt 302 terminations can 360 degree rotations on straight pin 303, formed one can 360 degree rotations revoliving arm (as shown in Figure 6).This structure is convenient to the quick-clamping of part.
Mould is fixed on the lower table of forcing press by No. 101 parts in the die holder 1 earlier, again briquetting 3, briquetting 4 and briquetting 5 are inserted respectively in the U-lag at No. 102 part two ends in the die holder 1 (as shown in Figure 4) and will No. 02 part of original section bar stuck-at-as Fig. 1 on.By No. 303 part pretensions, can carry out quick-clamping to part again.The structure (as shown in Figure 6) of briquetting 3, briquetting 4 and briquetting 5 is given on two web faces of section bar from top to bottom by the briquetting 2 of living at last and is exerted pressure.Thereby be pressed into needed angle (as shown in Figure 2).No. 303 parts next part that can change the outfit is unclamped in compacting after finishing, and carries out new work.
Use the utility model, when " Π " shape part processing, only need to make a cover universal mold, use " Π " shape section bar to be blank.Change the pressure size of each compacting and the length of press time during by compacting, just can suppress needed different angle " α ".Satisfy the demand of various different sizes " Π " shape forming parts, significantly reduce workload, the shortening product manufacturing cycle of " Π " shape part processing, enhance productivity, reduced production cost greatly.
