Description

Large curved surface stamping die of metal curtain wall plate

Technical Field

The utility model relates to a processing equipment of metal curtain wall panel especially relates to a stamping die for stamping forming metal curtain wall panel.

Background

The building curtain wall is usually composed of glass panels, metal panels, stone slabs and the like and a rear supporting structure, and the metal panel curtain wall can completely adapt to various complex modeling designs due to the excellent processing performance, the diversity of colors and the good safety of metal plates, can be added with convex-concave lines at will, can also be used for processing various types of curve lines, and is favored by architects to be developed rapidly.

The metal curtain wall panel is changed from an aluminum plastic plate and an aluminum plate to a stainless steel plate, and in recent years, architects favor the design of stainless steel curtain walls, so that the stainless steel curtain walls are more and more widely applied. The aluminum plate is selected as the curtain wall material, the price is low, the requirement on processing equipment is relatively low, and although the stainless steel panel has the advantages of durability and environmental protection, the stainless steel panel also has the characteristic of relatively high requirement on the processing equipment.

With the complexity of the design of metal curtain wall, metal panels such as aluminum panels and stainless steel panels are becoming more complex in shape and larger in size. The metal panel is formed by punching equipment in a punching mode, the forming accuracy and forming efficiency of the panel depend on a punching die, an upper punching die head and a lower punching die head of the existing punching die are of integral die structures, the end portions of the upper punching die head and the lower punching die head are provided with curved surface outlines of the panel, and due to the fact that plastic deformation force applied to the panel is uniformly distributed on the curved surface of the whole outline, the load of the punching equipment is increased, when the curved surface modeling is complex or the area of the curved surface is increased, the rated load of the punching equipment can be exceeded frequently, and accurate punching or punching forming can not be achieved. And when the curved surface area of curtain board panel is great, when the molding is complicated, the preparation of stamping die becomes very complicated, and the material use increases, and the mould cost increases, makes its stamping cost become very big to the limited curtain board panel of batch especially, influences the manufacturing and designing of panel.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a metal curtain wall large curved surface stamping die is provided, not only can realize the stamping forming of complicated, large tracts of land panel, and the preparation of being convenient for moreover can effectively reduce stamping cost.

In order to solve the problem, the utility model discloses a big curved surface stamping die of metal curtain board, mould on the punching press lower mould and the punching press of relative setting, the punching press face of mould on punching press lower mould and the punching press is identical, the punching press lower mould comprises the horizontal floor of die and the vertical floor of die that a plurality of intercrossing set up on punching press lower mould and the punching press, the profile face that the punching press face of mould corresponds the end and constitutes for horizontal floor of die and the vertical floor of die on punching press lower mould and the punching press.

In the structure, the lower stamping die and the upper stamping die do not adopt an integral punch head structure, but are composed of a plurality of transverse rib plates and longitudinal rib plates which are arranged in a crossed manner, the contour end of each rib plate acts on a stamped panel during stamping forming, and the contour end of each rib plate is in contact with the panel for stamping, so that the stamping contact area can be effectively reduced, the stamping force and the pressure of the contour end of each stamping rib plate are improved, the acting force on the unit stamping area is obviously improved, the stamping acting force of stamping equipment is effectively reduced, the forming accuracy and the forming efficiency of the stamping equipment are improved, and the rib plate type stamping die structure can accurately stamp more complex shapes and curtain wall panels with larger areas, and is particularly suitable for forming and processing plates with large-area and complex curved surface shapes. Also because the cross rib plate structure is adopted on punching press lower mould and the punching press mould, material and weight of the punching die are greatly reduced compared with the whole punching die, the manufacturing is more convenient, the manufacturing cost of the die is effectively reduced, and the structure of the cross rib plate breaks through the traditional punching die structural form, has more reasonable structure and lower cost, and is particularly suitable for manufacturing and processing curtain wall panels.

The utility model discloses a preferred embodiment, the horizontal floor of die and the vertical floor of die are inserted fixedly through the mutual card of floor inserting groove on it and are formed. The die structure is more convenient to manufacture and produce.

The utility model discloses a preferred embodiment, it is adjacent the horizontal floor of die is each other spaced and parallel arrangement, and is adjacent the vertical floor of die is each other spaced and parallel arrangement. The die transverse rib and the die longitudinal rib are arranged perpendicular to each other. The vertical parallel ribbed plates have high structural stability, and the weight and materials of the die are effectively reduced by arranging the ribbed plates at intervals.
