Abstract
The present invention relates to a split die for processing a rapid connecting structure, which solves the problems of low production efficiency and high cost of the prior art; furthermore, the prior art needs to be completed by a special device and professionals. The die is formed into a die whole body by a left and a right halves which are split, wherein the middle part of the die whole body is provided with a hollow mould cavity of which the upper part is smaller and the lower part is larger. The die can also be divided into an upper split forming plate and a lower die seat by using the bottom of the hollow mould cavity as a boundary, wherein an elastic body, a die core of which the section forms an inverted T shape, and a split block on the upper part of the die core are orderly arranged in a middle cavity of the die seat from bottom to top. The present invention causes the sheet metal to form a specific blister structure under the action of pressing force by utilizing the malleable mechanical properties of metal material in the offset limit of the metal material and is without the need of any connecting components; thereby, the connecting relationship is realized. The present invention has the advantages of simple structure, easy fabrication, broad application, low energy consumption, low cost and high efficiency; furthermore, the die is automatically separated, so the shape of a blister obtained after the processing can be emerged flashily and fluently from the die.
Description
[technical field]: the present invention relates to a kind of mould that is used for the fast joint structure between processing metal sheet material, particularly a kind of releasable mould.
[background technology]: the method for attachment between sheet metal is divided into two big classes usually, and promptly removable connection is connected with non-disconnectable.
Widely used in the releasable connection is to be threaded, and it need be realized by threaded connector.Be threaded and generally on connected piece, hole (tapping) earlier, connect together by screw bolt and nut.Make the junction that projection be arranged if be used for thin plate coupling nut and nut, influence is used.
Non-disconnectable connection generally is meant welding, riveted joint, method of attachment such as bonding.Wherein, welding needs special equipment, and process consumes energy big and produces and pollutes; Riveted joint needs rivet; Use and easily to make the bonding agent chemical property unstable and be restricted and be bonded in special occasions.The common defects of above-mentioned method of attachment is that production efficiency is low, and the cost height needs special equipment and professional to finish, the also easy connection failure phenomenon that occurs that has.
[summary of the invention]: it is low to the present invention seeks to solve prior art production efficiency, the cost height, and the problem that needs special equipment and professional to finish provides the releasable mould of fast joint structure between a kind of processing metal sheet material.
Mechanism of the present invention is to utilize metal material to have the mechanical performance of ductility in its yield limit, makes sheet metal form a kind of specific prominent bubble shape structure under the stamping press effect, thereby realizes annexation.Particularly the present invention does not use traditional method of attachment, and need not punch on connected piece does not need to install connector and just can form syndeton in moment yet.
Releasable mould provided by the invention constitutes a mold integral by separable left and right sides two halves, and the centre of mold integral is up-small and down-big hollow die cavity.Hollow die cavity cross section is circular, square, the rectangle of band chamfering.
This mould can be the boundary from the bottom of hollow die cavity also, releasable profiled sheeting and bottom die holder two parts of being divided into top, be the up big and down small cavity that is back taper in the die holder, be placed with core rod, the both sides, core rod top that elastomer, cross section be inverted T-shaped in the cavity from bottom to top successively and respectively be placed with a up big and down small explant that coincide with the cavity inner wall inclined-plane, the upper surface of explant contacts with releasable profiled sheeting bottom surface respectively.
Wherein elastomer is elastic caoutchouc, rubber and plastic, nylon or spring.
Advantage of the present invention and good effect:
1. the present invention utilizes the mechanical performance that metal material is ductile in its yield limit, makes sheet metal form a kind of specific protruding bubble structure under the stamping press effect, thereby realizes annexation.
2. the present invention is different with traditional method of attachment, does not punch on connected piece, and without any need for connector, the present invention can make moment formation syndeton between the sheet metal, and it is simple in structure, and is easily manufactured, and the scope of application is wide, and it is low to consume energy, and cost is low, the efficient height.
3. mould of the present invention adopts automatic isolating construction, and the protruding bubble shape that makes processing obtain later on can take off from mould smoothly in moment.
4. the fast joint structure that processes of the present invention bears the transverse load ability and is connected quite with bolt through puller system experiment contrast.
5. the present invention does not produce any pollution in manufacturing, use.
6. the present invention can use in indoor or on-the-spot processing.
7. mould of the present invention can be used for being connected between processing sheet and thin plate, thin plate and angle steel, thin plate and I-steel, thin plate and channel-section steel etc.; Can be widely used in the household electrical appliances manufacturing, numerous areas such as automobile, aircraft, steamer, building, national defence.
[description of drawings]:
Fig. 1 is embodiment 1 a releasable mould concrete structure schematic diagram;
Fig. 2 is embodiment 2 releasable mould concrete structure schematic diagrames.
[specific embodiment]:
Embodiment 1:
As shown in Figure 1, releasable mould provided by the invention constitutes a mold integral by left and right sides two halves releasable mould 3, and the centre of mold integral is up-small and down-big hollow die cavity.Hollow die cavity cross section can be circular, oval, also can be the square or rectangle (this example is first-selected circular) of band chamfering.
During use, connected piece 2 (sheet metal) is placed on the releasable mould 3, because metal material has the mechanical performance of ductility in its yield limit, connected piece 2 is under drift 1 effect, form 9 (as shown in the figure) of a kind of specific prominent bubble shape structure, thereby realize annexation.
When drift is up when finishing punching press, releasable mould 3 is separated to both sides, can take off connected piece 2.
Embodiment 2:
As shown in Figure 2, on the basis of embodiment 1, this mould can be the boundary from the bottom of hollow die cavity also, releasable profiled sheeting 4 and bottom die holder 8 two parts of being divided into top, be the up big and down small cavity that is back taper in the die holder, be placed with core rod 6, the both sides, core rod top that elastomer 7, cross section be inverted T-shaped in the cavity from bottom to top successively and respectively be placed with a up big and down small explant 5 that coincide with the cavity inner wall inclined-plane, the upper surface of explant contacts with releasable profiled sheeting bottom surface respectively.Wherein elastomer can be elastic caoutchouc, rubber and plastic, nylon or spring (this example is selected elastic caoutchouc).
Because forming a kind of protruding bubble structure later on through this Mould Machining, workpiece to be machined could realize annexation, so this example has been invented automatic isolating construction mould.Promptly, mould is blocking when drift 1 descending punching press, when drift is up when finishing punching press, core rod 6 moves up under the elastic force effect of elastomer 7, drive simultaneously explant 5 along die holder 8 inwall inclined-planes laterally oblique upper move, and make releasable profiled sheeting 4 separate abduction, can from mould, take off smoothly in moment with the protruding bubble shape that guarantees workpiece to be machined 2 (connected piece).
