The utility model is provided with the heating device through the first plate body, which makes the heating device evenly heat the upper and the lower dies, thereby realizing the superplastic shaping of aluminum plates and increasing the efficiency, simultaneously, the second plate body is provided with the cooling device, which effectively insulates heat from the upper slide block and the work bench, and prevents the affection to the precision of machine tools because of heating.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of accurate box body superplastic forming die.
Background technology
At present, the extrusion molding dies that uses on the aluminium sheet extrusion line generally adopts the cold-stamped mode, plasticity, the impact flexibility variation of extruding back aluminium sheet, and also the residual stress of aluminium sheet is big, and the aluminium sheet plastic forming is difficult.
The utility model content
The purpose of this utility model is to provide a kind of accurate box body superplastic forming die, and wherein, heater can carry out appropriateness, uniform heating to mould, realizes the superplastic formation to aluminium sheet.
For achieving the above object, a kind of accurate box body superplastic forming die that the utility model provides, upper bolster upwards is provided with first plate body, first plate body is positioned on the side of top shoe second plate body is set, die shoe is provided with first plate body downwards, and first plate body is positioned on the side of workbench second plate body is set, and evenly arranges heater in first plate body, evenly arrange cooling device in second plate body, the upper and lower mould that cooperatively interacts links to each other with upper and lower die holder respectively.
The utility model is by being provided with heater in first plate body, heater is evenly heated upper and lower mould, the superplastic formation that helps aluminium sheet, improved efficient, simultaneously, in second plate body, arrange cooling device, on the one hand top shoe and workbench are carried out effectively heat insulationly, can prevent on the other hand owing to heat and influence machine tool accuracy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of accurate box body superplastic forming die, upper bolster 31 upwards is provided with first plate body 10, first plate body 10 is positioned on the side of top shoe second plate body 20 is set, die shoe 41 is provided with first plate body 10 downwards, first plate body 10 is positioned on the side of workbench second plate body 20 is set, evenly arrange heater in first plate body 10, evenly arrange cooling device in second plate body 20, the upper and lower mould 32,42 that cooperatively interacts links to each other with upper and lower die holder 31,41 respectively, and product to be processed is between upper and lower mould 32,42.In the utility model, product to be processed is an aluminium sheet 80, as shown in Figure 1.
In conjunction with Fig. 1, between the described upper bolster 31 and first plate body 10, be connected by screw 12 between the die shoe 41 and first plate body 10, be connected between first plate body 10 and second plate body 20.Described heater is a heating rod, evenly offers through hole 11 on first plate body 10, and the number of through hole 11 is decided as required, and heating rod penetrates the inside that through hole 11 is arranged in first plate body 10 equably one by one, realizes the even distribution heating to first plate body 10.First plate body 10 that is built-in with heating rod is passed to upper and lower die holder 31,41 equably with heat, by upper and lower die holder 31,41 heat is passed to upper and lower mould 32,42 again, upper and lower mould 32,42 press down, in the extrusion aluminum board 80, aluminium sheet 80 is carried out preheating, the temperature of heating rod can be controlled by the temperature switch board, guarantees to realize the superplastic formation to aluminium sheet 80.In the utility model, patrix is a punch, and counterdie is a die.
In conjunction with Fig. 1, to offer on described second plate body 20 and be the hole 21 that circuitous shape is arranged, cold water flows through in the hole 21 and promptly forms cooling device.Between first plate body 10 and the top shoe, between first plate body 10 and the workbench second plate body 20 is set, on the one hand top shoe and workbench are carried out effectively heat insulationly, can prevent on the other hand owing to heat and influence machine tool accuracy.
In conjunction with Fig. 1, the two ends of described upper and lower die holder 31,41 are sheathed heating collar 50 respectively, upper and lower die holder 31,41 is directly heated, coat insulation asbestos 60 with heating collar 50, first plate body, 10 contacted positions on the upper and lower die holder 31,41, insulation asbestos 60 are used for heat insulation to external world, slow down heat and distribute.The periphery of heating collar 50, insulation asbestos 60 is provided with shell 70, and shell 70 is fixed on the upper and lower die holder 31,41 by screw.
In sum, core of the present utility model is to heat by 10 pairs of moulds of first plate body of built-in heating rod, indirectly aluminium sheet 80 is heated by mould again, and the aluminium alloy plate 80 that is heated is realized superplastic formation through the mould extruding.
