embodiment 1
The present embodiment composition graphs 1,2,3 is described further, and what the present embodiment related to is applicable to the continuously shaped mould of thin-walled composite element, comprises right baffle-plate 1, front apron 2, backboard 7, formpiston 3, soft mode 4, right baffle plate 5, former 6 successively.
Described soft mode material comprises silicon rubber, and thickness is 10mm ~ 30mm, and profile is the tangent ruled surface of many circular arcs; Described soft mode profile arc radius is 40 ~ 80mm.The mode that described soft mode 4 position on formpiston 3 is fixing: be first glued in metal positive by soft mode, by the relative position being screwed onto the right baffle-plate 1 of formpiston 3, front apron 2, backboard 7 and right baffle plate 5 respectively and fixing soft mode 4; Make its not slippage in forming process.
Described right baffle-plate 1, right baffle plate 5 material are steel or aluminium alloy, and adopting is spirally connected is fixed on formpiston 3 arranged on left and right sides, are specially on the end face of the elongated end being arranged on the both sides extension to the left and right of formpiston 3 convex surface, its highly all little than soft mode 4 thickness 3 ~ 6mm.Described ladle is containing hot-rolled steel, forged steel; Described aluminium alloy comprises 2A12,2A14.
The material of described front apron 2, backboard 7 is steel or aluminium alloy (hot-rolled steel, forged steel, 2A12,2A14), employing is spirally connected and is fixed on the forward and backward end of formpiston 3, upper end curved surface is lower than soft mode 4 thickness 3 ~ 6mm, and curved surface arc radius is consistent with soft mode 4 is: 40 ~ 80mm.
The arc radius of the curved surface of described mold cavity block 6 and formpiston 3 is 40mm ~ 80mm, and length direction is not limit.
Prepare the continuously shaped mould for ultrathin component of the present embodiment, specifically comprise the steps:
Step one: it is highly 120mm that employing steel (hot-rolled steel) is produced, width is 250 ~ 400mm formpiston and former, the subsequent corrosion of its profile is 55mm.
Step 2: adopt silicon rubber casting thickness to be the soft mode of 10 ~ 30mm, subsequent corrosion is 55mm, width 240mm.
Step 3: adopt 2# sand paper male mold surfaces to be polished, soft mode is glued to relevant position by gluing.
Step 4: adopt aluminium alloy (2A12) to process right baffle-plate, right baffle plate, front apron, backboard.Be screwed onto the relevant position of formpiston respectively.
Step 5: each profile of post processing, guarantees to meet designing requirement.
In the utility model, each baffle plate be spirally connected around formpiston 3 is position-limiting action, is not moved when ensureing that soft mode 4 is subject to frictional force in composite continuous forming process.
In hot pressing, former 6 and the closed heating of formpiston 3 are simultaneously because soft mode 4 has certain thermal coefficient of expansion and modulus, and thermal expansion can occur when it is heated, apply thermal expansion force further to product, the porosity reducing goods is better than 0.3%.
