Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the present invention.
As shown in the figure, a kind of rectangular mould forging apparatus, comprises mould and mould bases, and described mould comprises mold 9 and bed die 3, and described mould bases comprises upper bolster 8 and die shoe 1,
For the ease of guiding during matched moulds, die shoe 1 is provided with three leads, upper bolster 8 is provided with three pilot holes matched with described lead.
Described upper bolster 8 and the opposite face of die shoe 1 are respectively equipped with a groove, upper padding plate 10 and lower bolster 2 is respectively equipped with in described two grooves, mold 9 and bed die 3 are separately positioned on upper padding plate 10 and lower bolster 2, and be fixed on upper bolster 8 and die shoe 1 by the respective compressing member be arranged between upper groove and mold and between low groove and bed die, the inwall of upper groove and low groove is respectively equipped with for the positioning reference plane 14 of locating that contacts with the side of corresponding mould, because described mould outline is rectangle, described locating surface generally arranges two, two described positioning reference planes are vertically arranged mutually, in order to ensure the mold alignment of upper/lower die, the best relative set of positioning reference plane in upper and lower die holder groove.A datum level is illustrate only in the present embodiment.As required another datum level can be set on another perpendicular groove inner wall in practical application.
As shown in Figure 2, die shoe compressing member used comprises the briquetting I 11 with raised line,
With the briquetting II 7 of the arc conical surface and side be cylindrical cambered surface, opposite side be plane briquetting III 15 and for each briquetting being fixed on the connector on die shoe.
Raised line and the side fit depressions be located on bed die 3 one sides of briquetting I 11, another side relative with face, raised line place in briquetting I 11 is provided with detent, detent matches with the positioning convex be located on low groove inwall, another face relative with the arc conical surface in briquetting II 7 is plane, this plane matches with the opposite face in face, groove place, side in bed die 3, form the structure that briquetting II 7 and briquetting I 11 are oppositely arranged, on the inwall of low groove be provided with the mating surface consistent with the arc conical surface of briquetting II 7.
Briquetting III 15 is oppositely arranged with the datum level of low groove, and the arcwall face of described briquetting III 15 matches with the arc mating surface consistent with it be arranged on low groove inwall.
During installation, the side groove of bed die 3 is matched with the raised line of briquetting I 11, detent on briquetting I 11 is matched with the positioning convex on low groove inwall, another side perpendicular with side groove surface of bed die is close on positioning reference plane 14, adjustment briquetting III 15, screw all connectors, bed die 3 is fixed on die shoe 1.
For the ease of installation and removal, connector for fixing briquetting I 11 uses studs 12, during installation, by studs 12 one end to close with the corresponding threaded holes be located on die shoe 1 and be connected, the other end of stud is through attaching nut after the through hole be located on briquetting I, between described briquetting I 11 and die shoe 1, there is gap, work as tightening nut like this, because be fixing between stud and die shoe, so briquetting I 11 downwards by bed die 3 to being pressed on lower bolster, thus bed die 3 and die shoe 1 are fixed together.
In order to make dismounting lighter, through hole on described briquetting I 11 is designed to counter bore structure in the one end near corresponding die holder, the one section outer cover of described studs 12 in counterbore has Compress Spring 13, when compressing bed die 3, Compress Spring 13 is compressed, when needing dismounting, by bed die 3 upwards jack-up when unclamping 13 reinstatement of nut Compress Spring.
Connector for fixing briquetting II 7 is bolt II 5, preferably, bolt II 5 and briquetting II 7 can link together mutually rotationally, particularly, as shown in Figure 1, can by but fixing back-up ring 6 is welded on bolt through the other end after briquetting II 7 near the position of briquetting, such structure when disassembled, unclamp bolt II 5, briquetting II 7 also can upwards rise together, and dismantlement work is more prone to.
Further, place corresponding to bolt II 5 on die shoe 1 arranges unthreaded hole, and the lining being provided with internal thread in unthreaded hole matches with described bolt II 5.Such structure is not only convenient to process the maintenance after being also convenient to threaded portion wearing and tearing.
Upper bolster and all roughly the same with die shoe with the structure of relevant each parts, mounting means too, repeats no more herein.
Use the present invention, because compacted of mould is fixed in the groove of corresponding die holder, be applied with certain prestressing force to mould, can ensure that mould in use can not burst apart; Adopt this kind of structure forging press, for different forging products, the appearance and size of mould can use unified specification, backing plate can be avoided so in use not yielding, also extend the mold use life-span further conversely.
