Abstract

The utility model relates to a curved mould used for a special shaped curved surface rapid shaping machine, which belongs to the sheet metal processing field. The curved mould is formed by the integral casting of an upper mould connecting seat, a steel ball, and an upper mould body through rubber; a lower mould pad is rigidly connected with an elastic block; the elastic block is tightly arranged on a lower mould seat and then axially fixed by a gland bush; the gland bush is fixed on the lower mould seat; ironwood is arranged in the lower mould pad; and the elastic block is formed by the casting of an outer sleeve and an inner sleeve through the rubber. The utility model has simple, compact and reasonable structure, the moulded workpiece has smooth surface and very little damage, the curvature of the workpiece to be bent can be adjusted arbitrarily, no other mould is additionally required during the manufacturing process and the moulding of the workpiece is very easy.

Description

The curve mold of using on the abnormal curved surface fast forming machine

Technical field

The utility model relates to the curve mold of using on a kind of abnormal curved surface fast forming machine, specifically is specifically designed to the shaping of sheet material under various degree of crook of unlike material, belongs to metallic plate metalworking industry.

Background technology

In prior art, be used for multiple industries such as Aeronautics and Astronautics, locomotive, automobile, shipbuilding, use same pair of curve mold, making the curve surface work pieces of various differently curved degree can't accomplish of it, need suppress respectively just and can accomplish by the mould that uses different curvature, therefore mould kind, the specification that needs is a lot, useless power when work is useless, and efficient is low-cost high.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby the curve mold of using on a kind of abnormal curved surface fast forming machine is provided, makes workpiece deformation by the way that workpiece is progressively suppressed downwards, the degree of workpiece deformation is by the downward drafts decision of curve mold, press down more, bending curvature is big more, and degree of crook is just dark more, and the process in the middle of this can be controlled arbitrarily by the operator, the course of work is very free and relaxed, save time and laborsaving, the efficient height, and cost is low.

Main solution of the present utility model is achieved in that

The utility model mainly is made up of mold and bed die two parts; Described mold is formed by the specific rubber integral cast by patrix joint chair, upper die body, steel ball.Adopt the elastomer block flexibility to be connected between described die shoe and the following die-cushion, following die-cushion and elastomer block connect with little cross recessed countersunk head sscrew is rigidly connected.Elastomer block is glanded and is fixed on the die shoe, and gland is fixed on the die shoe with grand cross groove sunk screw.Hardwood is placed on down in the die-cushion.Make protector with sheath again between described die-cushion down and the die shoe.

Place hardwood in the die-cushion under described.Described elastomer block is formed by the specific rubber integral cast by interior cover and overcoat.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Used the progressively shaping principle of sheet metal dexterously in design, the work that needed multiple kinds of molds just can finish in the former workpiece processing has been converted on a kind of universal mold finishes, the Forming Workpiece smooth surface is damaged minimum; The curvature of required curved workpieces can be controlled arbitrarily, and is changeable, and do not need to add any attached assistant engineer's tool in manufacturing process again, and component shaping is very free and relaxed.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1, the utility model is made up of patrix 1 and counterdie.Wherein patrix 1 is formed by specific rubber c integral cast by patrix joint chair a, steel ball b, upper die body d again; Counterdie is made up of hardwood 2, grand cross groove sunk screw 3, following die-cushion 4, gland 5, elastomer block 6, little cross recessed countersunk head sscrew 7, die shoe 8, sheath 9.Elastomer block 6 is formed by specific rubber f casting by overcoat e and interior cover g.

The utility model patrix 1 is connected with the abnormal curved surface fast forming machine respectively with die shoe 8.Mold is connected in by patrix joint chair a does oscillating movement up and down on the drift of abnormal curved surface fast forming machine, bed die is fixed on transfixion on the support.Patrix 1 is formed by specific rubber c integral cast by patrix joint chair a, steel ball b, upper die body d.In bed die, following die-cushion 4 and elastomer block 6 are rigidly connected by little cross recessed countersunk head sscrew 7, and elastomer block 6 close-fittings are used gland 5 axial restraints again on die shoe 8.Wherein elastomer block 6 is formed by specific rubber f casting by overcoat e and interior cover g.Gland 5 usefulness grand cross groove sunk screws 3 are fixed on the die shoe 8.Having refilled sheath 9 in addition between die-cushion 4 and the die shoe 8 down, play the attractive, decorative effect.In the die-cushion 4 hardwood 2 is housed under described.

The operation principle of the utility model mould and the course of work

Sheet metal workpiece 10 is placed on the bed die, and patrix 1 is done oscillating movement up and down with abnormal curved surface fast forming machine drift, when patrix 1 is descending touch workpiece after, workpiece just begins distortion.Owing to the hardwood 2 in bed die exceeds die-cushion 4 down, therefore be actually to be supported on the hardwood 2 at the workpiece on the bed die, in workpiece and following die-cushion 4, there is certain clearance.Constantly descending when pressing down workpiece when patrix 1, this gap just constantly diminishes, and the distortion of workpiece just constantly increases, till the distortion of workpiece meets people's requirement.Because workpiece size is generally all bigger, therefore the operator needs ceaselessly travelling workpiece in the course of the work, so that whole work-piece all obtains the distortion that requires.Because steel ball b and specific rubber c also have certain flexibility effect when transmitting hitting power in patrix 1, so patrix 1 has the anti-bias load ability.Die-cushion 4 is to be connected by elastomer block 6 with die shoe 8 down in bed die, so bed die has the flexibility and the anti-bias load ability of trace equally.Owing to all adopt specific rubber to connect in the design process of whole mould up and down, so mould is extremely steady in the course of the work, less to the impulsive force of workpiece, what component shaping used is flexible force, makes the Forming Workpiece surface damage minimum therefrom.
