Abstract

The utility model discloses an automobile aluminum part forming mould which comprises an upper mould frame (1), a lower mould frame (2), an upper cavity partial material press device (3), a lower cavity partial material press device (4), an upper mould trimming forming tool block (5) and a lower mould trimming forming tool block (6). The upper cavity partial material press device (3) and the upper mould frame (1) are connected through a spring and a nitrogen cylinder, the lower cavity partial material press device (4) and the lower mould frame (2) are connected through a spring or a nitrogen cylinder, the upper mould trimming forming tool block (5) is installed on the upper mould frame (1), and the lower mould trimming forming tool block (6) is installed on the lower mould frame (2). By means of the structure, trimming and flanging processes can be finished on the same mould so as to reduce moulds and press machines, reduce cost and facilitate maintenance. Furthermore, allowance accumulation between multiple processes of multiple original forming moulds is reduced, and product stability is good.

Description

The mould that is used for automobile aluminum work pieces
Technical field
The utility model relates to a kind of forming die structure, especially relates to a kind of mould for automobile aluminum work pieces.
Background technology
For the making of automotive metal piece processing, particularly alumiaum article thermal insulation board for example, present moulding process mainly adopts four procedures: be respectively the moulding of first operation, mold the plate moulding; The second operation work edge-cutting and hole-punching, cut unnecessary plate and go out the institute porose; The three process flange is first translated into perpendicular edge to needs bound edge part; The 4th procedure bound edge is carved characters.Adopt this technique to need four pairs of moulds and press, the manufacturing cost in early stage of mould is large, the construction cycle is long, and the production efficiency of four procedure moulding is also dissatisfied; The most important product quality problem that still stamps out, the tolerance accumulative total due to multiple working procedure makes the stability of product not good, and this has brought series of problems also for client's follow-up punching press.In addition, owing to adopting four pairs of moulds and press, maintenance is also inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of mould that is used for automobile aluminum work pieces that trimming and overturning process are completed on a secondary mould.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises top mold frame and lower mold holder, the local eccentric swage of epicoele and the local eccentric swage of cavity of resorption, patrix deburring forming-tool piece and counterdie deburring forming-tool piece, adopt spring or nitrogen cylinder to connect between the local eccentric swage of epicoele and top mold frame, adopt spring or nitrogen cylinder to connect between the local eccentric swage of cavity of resorption and lower mold holder, patrix deburring forming-tool piece is arranged on top mold frame, and counterdie deburring forming-tool piece is arranged on lower mold holder.
The incision partial depth of patrix deburring forming cutter piece deburring sword described in the utility model is 8mm, with 45 ° of hypotenuse transition of knife back junction employing, high 2 ~ the 4mm of edge of a knife aspect ratio flange edge of a knife height of lower mold forming edge iron piece deburring side, knife back place is the backrest of high 30mm.
The said structure that the utility model adopts solves trimming and overturning process on a secondary mould, can save mould and press reducing costs, and be convenient to maintenance; Also reduced the tolerance accumulative total between originaling forming multi-mould multiple operation, made the stability of product better.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
1, top mold frame 2, lower mold holder 3, the local eccentric swage 4 of epicoele, the local eccentric swage 5 of cavity of resorption, patrix deburring forming-tool piece 6, counterdie deburring forming-tool piece 7, the trimming edge of a knife 8, the flange edge of a knife 9, plate
The specific embodiment
By accompanying drawing as can be known, the mould that should be used for automobile aluminum work pieces comprises top mold frame 1 and lower mold holder 2, the local eccentric swage 3 of epicoele and the local eccentric swage 4 of cavity of resorption, patrix deburring forming-tool piece 5 and counterdie deburring forming-tool piece 6, between the local eccentric swage 3 of epicoele and top mold frame 1, employing spring or nitrogen cylinder connect, between the local eccentric swage 4 of cavity of resorption and lower mold holder 2, employing spring or nitrogen cylinder connect, patrix deburring forming-tool piece 5 is arranged on top mold frame 1, and counterdie deburring forming-tool piece 6 is arranged on lower mold holder 2.The incision partial depth of described patrix deburring forming cutter piece 5 deburring swords is 8mm, adopts 45 ° of hypotenuse transition with knife back junction, the high 2 ~ 4mm of edge of a knife aspect ratio flange edge of a knife height of lower mold forming edge iron piece 6 deburring sides, and knife back place is the backrest of high 30mm.During work, plate 9 is placed on the local eccentric swage 4 of cavity of resorption, top mold frame 1 is descending, the local eccentric swage 3 of epicoele is descending, utilize the up and down binder first with plate 9 moulding, utilized the trimming edge of a knife 7 to cut the peripheral waste material of plate 9 on earth at top mold frame 1 stroke, and then utilize the flange edge of a knife 8 to carry out flange, it is downward that the flange edge of a knife 8 needs all the position of bound edge first to translate into straight flange, and top mold frame 1 stroke can be completed moulding, trimming and overturning process on earth the time; The flange edge of a knife and the trimming edge of a knife of patrix deburring forming-tool piece 5 are to make on same bloom, are convenient to like this die debugging and the maintenance in later stage.
The utility model is by the compacting of punch press, and upper and lower mold forming edge iron piece reduces with plate separation, moulding the phenomenon that the difficult salient point of the Material Flow that comes because of many strips is pulled open.Part shape relative complex due to the making of annular knurl aluminium sheet, so rise in order to solve part, the spy arranges local eccentric swage in upper and lower die cavity, regulates local pressure-plate-force by adjusting spring specification, spring length or spring travel, guarantee that part does not namely rise, salient point is not broken again.
