Abstract

The utility model relates to an adjustable arc-shaped die. The adjustable arc-shaped die comprises an upper die assembly and a lower die assembly, wherein the upper die assembly is formed by a plurality of upper die plates in a overlap mode, and the lower die assembly is formed by a plurality of lower die plates in a overlap mode. An upper die plate is connected with another upper die plate through an upper die screw, and a lower die plate is connected with another lower die plate through a lower die screw. The lower portion of the upper die assembly is an arc-shaped protrusion, the upper portion of the upper die assembly is provided with an upper die connecting piece which is connected with a numerical control bending machine. The upper portion of the lower die assembly is provided with an arc-shaped groove, the arc-shaped groove is matched with the arc-shaped protrusion of the upper die assembly, and the lower portion of the lower die assembly is provided with a lower die connecting piece which is connected with the numerical control bending machine. The adjustable arc-shaped die has the advantages that by adoption of cambered surface pressed forming, not only is continuity of the cambered surface good, but also curve is smooth and beautiful; widths of the upper die assembly and the lower die assembly can be adjusted according to the width of an element needing processing and the adjustable arc-shaped die can be used for processing of different elements.

Description

Adjustable arcuate die

Technical field

The utility model relates to processing mold, particularly the adjustable arcuate die of a kind of Machining of Curved Surface for the sheet metal structural field.

Background technology

Existing panel beating curved-surface structure processing, all by numerical control bender together non-90 ° of bending aftershapings, there are a lot of bending vestiges the moulding rear surface, both rough, not attractive in appearance yet, simultaneously since many uncertain factors of each processing cause before and after the cambered surface of part inconsistent, have a strong impact on the use of part and attractive in appearance, working (machining) efficiency is low.

The utility model content

Technical problem to be solved in the utility model provide a kind of can adjustable arcuate die, this arcuate die is not only simple in structure, easy to use, and can make the part by one-step moulding, has guaranteed part curved surface smooth and beautiful appearance.

The technical scheme that the utility model adopts is:

A kind of adjustable arcuate die, include upper die component and lower membrane module, described upper die component is formed by stacking by a plurality of upper matrixs, described lower membrane module is formed by stacking by a plurality of lower matrixs, be connected by the patrix screw rod between described upper matrix and the upper matrix, be connected by the counterdie screw rod between lower matrix and the lower matrix; The bottom of described upper die component is arc convex, and the top of upper die component is provided with the patrix connector that is connected with numerical control bender; The top of described lower membrane module is provided with arc groove, and the arc convex of this arc groove and upper die component is suitable, and the bottom of lower membrane module is provided with the counterdie connector that is connected with numerical control bender.

Press such scheme, be provided with the groove of avoiding the processing parts projection at arc convex.

Press such scheme, be respectively equipped with the hole on described upper die component and the lower membrane module, the patrix cushion block that load-bearing is used passes the hole on the upper die component; The counterdie cushion block that load-bearing is used passes the hole on the lower membrane module.

The beneficial effects of the utility model are: it is compressing that 1, the utility model adopts cambered surface, and not only the cambered surface continuity is good, and the curved surface smooth and beautiful appearance.2, the width of processing parts is as required adjusted the width of upper die component and lower membrane module, can be suitable for the processing of different parts, and is not only easy to use, and the scope of application is wide.3, have groove on the lower surface of upper die component, can dodge out the projection of processing parts, prevent when compressing destruction to processing parts.4, owing to be one-shot forming, not only the consistent performance of part accesses guarantee, guaranteed the in batches curved surface layman unification of part, and working (machining) efficiency is high.

Description of drawings

Fig. 1 is decomposing schematic representation of the present utility model.

Fig. 2 is stereogram of the present utility model.

Among the figure: 1, upper die component, 2, the patrix connector, 3, groove, 4, lower membrane module, 5, the counterdie connector, 6, patrix cushion block, 7, the patrix screw rod, 8, the patrix pad, 9, the patrix nut, 10, counterdie cushion block, 11, the counterdie screw rod, 12, the counterdie pad, 13, the counterdie nut.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 1 and Fig. 2, a kind of adjustable arcuate die, it includes upper die component 1 and lower membrane module 4, described upper die component 1 is comprised of the upper matrix that the steel plate Laser Processing forms several, described lower membrane module 4 is by several lower matrixs that is formed by the steel plate Laser Processing, be connected by patrix screw rod 7, patrix pad 8, patrix nut 9 between upper matrix and the upper matrix, be connected by counterdie screw rod 11, counterdie pad 12, counterdie nut 13 between lower matrix and the lower matrix; The bottom of described upper die component 1 is arc convex, and the top of upper die component 1 is provided with the patrix connector 2 that is connected with numerical control bender; The top of described lower membrane module 4 is provided with arc groove, and the arc convex of this arc groove and upper die component 1 is suitable, and the bottom of lower membrane module 4 is provided with the lower membrane module 5 that is connected with numerical control bender; Be respectively equipped with square hole on described upper die component 1 and the lower membrane module 4, the patrix cushion block 6 that load-bearing is used passes the square hole on the upper die component 1; The counterdie cushion block 10 that load-bearing is used passes the square hole on the lower membrane module 4.

In the present embodiment, in order to avoid the projection on the processing parts, can establish groove 3 at arc convex.

The width of described upper die component and described lower membrane module is decided by the width of processing parts, determines particular location and the quantity of groove 3 according to the projection on institute's processing parts curved surface, to reach the purpose of dodging projection.According to the part adjustment and assemble described upper die component and described lower membrane module, just can the processing parts curved surface.

The utility model adopts stacked system to regulate the curved surface width, and dodges the projection on the curved surface, and is disposable compressing to curved surface part, can guarantee the smooth continuity of curved surface, in batches the uniformity of part.

The above; only being preferred embodiment of the present utility model, is not that the utility model is done any pro forma restriction, and those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification; equivalent variations or modification all drop in the protection domain of the present utility model.
