Abstract
The invention relates to an end partial subsidence forming mold for an aluminum alloy L-shaped angle section part and applications thereof. An upper mold body and a lower mold body which are of a split structure are adopted, and the lower end face of the upper mold body and the upper end face of the lower mold body are fold line end faces of a complementary structure. A baffle is arranged on the side end face of the lower mold body and corresponds to the side end face of the lower mold body in shape, and locating pins are arranged on the baffle. A clamping and locating process is used for inspecting processing of the mold, the geometric shape and the size precision of the part can be guaranteed, the processing cost is low, the efficiency is high, and the end partial subsidence forming mold is suitable for small batch production of airplane parts.
Description
Technical field
The present invention relates to the sagging shaping dies in local, a kind of aluminium alloy L shape angle section part termination and application, belong to mechanical aviation manufacture field.
Background technology
Aircraft machine aluminium alloy L shape angle section part is aircraft common part, and shape mostly is arc, and part termination, with sinking, needs to form the final accessory size of guarantee part by partial operation.
Summary of the invention
The technical problem to be solved in the present invention is to provide the sagging shaping dies in local, a kind of aluminium alloy L shape angle section part termination and application, realizes local, L shape angle section part termination and sink shaping accurately, meet Element Design and instructions for use.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: sink local, a kind of aluminium alloy L shape angle section part termination shaping dies, the upper die and lower die of split-type structural, patrix lower surface and counterdie upper surface are the broken line end face in complementary structure, the side end face of counterdie is provided with baffle plate, baffle shapes is corresponding with counterdie side end face shape, and baffle plate is provided with alignment pin.
Utilize an application for the sagging shaping dies in local, aluminium alloy L shape angle section part termination, comprise the steps:
1) sagging finishing die is carried out on punch press installation to fix, counterdie and baffle plate flat-nose pliers are fixed on punch press, adjustment punch press and flat-nose pliers position, upper die and lower die and baffle plate die-closed position correct;
2) open punch press patrix is risen, flat-nose pliers is unclamped counterdie and flapper gap are strengthened;
3) press alignment pin and location, counterdie side at the hand-held part in punch press side, part is installed on mould, flat-nose pliers clamping is ensured that parts fixation is firm simultaneously;
6) opening punch press makes patrix decline, and carries out stamping processing, and patrix arrives after minimum point completes punching press and rises;
7) unclamp flat-nose pliers, side shield and counterdie are separated, take out part;
8) part after shaping is tested, after confirming that part is qualified, repeat stamping step, realize processing new part.
The beneficial effect that the present invention brings is: to be sunk to aluminium alloy L shape part termination by the mould of split-type structural and process for stamping and process, geometry and the dimensional accuracy of part can be ensured, processing cost is low, and efficiency is high, is applicable to airplane parts small lot batch manufacture.

Detailed description of the invention
As depicted in figs. 1 and 2, sink local, a kind of aluminium alloy L shape angle section part termination shaping dies, the patrix 1 of split-type structural and counterdie 2, patrix 1 lower surface and counterdie 2 upper surface are the broken line end face in complementary structure, the side end face of counterdie 2 is provided with baffle plate 3, baffle plate 3 shape is corresponding with counterdie 2 side end face shape, and baffle plate is provided with alignment pin.
Utilize an application for the sagging shaping dies in local, aluminium alloy L shape angle section part termination, comprise the steps:
1) sagging finishing die is carried out on punch press installation to fix, counterdie 2 and baffle plate 3 are fixed on punch press with flat-nose pliers, adjustment punch press and flat-nose pliers position, and patrix 1, counterdie 2 and baffle plate 3 die-closed position are correct;
2) open punch press patrix 1 is risen, flat-nose pliers is unclamped counterdie 2 and baffle plate 3 gap are strengthened;
3) press alignment pin and location, counterdie 2 side at the hand-held part in punch press side, part is installed on mould, flat-nose pliers clamping is ensured that parts fixation is firm simultaneously;
6) opening punch press makes patrix 1 decline, and carry out stamping processing, patrix 1 arrives after minimum point completes punching press and rises;
7) unclamp flat-nose pliers, side shield 3 and counterdie 2 are separated, take out part;
8) part after shaping is tested, after confirming that part is qualified, repeat stamping step, realize processing new part.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, some modification and improvement can also be made, also should be considered as belonging to protection scope of the present invention.
