The present invention relates to be used for the molding device that metal sheet is shaped.
Can embed along the downward storke of patrix in the counterdie and the shaping concave shape all uses pattern generally speaking in order to make as the metal sheet of workpiece material.
In general, when the metal sheet as workpiece material is shaped with this concave shape, earlier workpiece material is placed on the counterdie, its active pattern that moves through downward vertically by patrix moves the passive pattern of counterdie then, thereby along a horizontal side workpiece material is implemented processing.After the processing of finishing material, patrix is raised, and initiatively pattern is also followed under spring action to drawback movement.
In the molding device of this conventionally form, passive pattern slides along horizontal a certain side from the outside of workpiece material, its shaped portion makes material forming thus, the shaped portion of this passive pattern is made into material forming and partly has identical shaped single member, yet, after finishing materials processing, the shaped portion that is used for the counterdie of place work piece material must be able to take out from counterdie.For this reason, be necessary after finishing processing finished material is taken out, its way or separately and make it return with the recessed portion of counterdie, or remove and make finished material to move forward at the rear portion of recessed portion.Recessed degree problem hour is fewer.But, if the recessed excessive or finished material of degree is an elongated moulding formula part with channel-section-such as the automobile front column of being made by sheet material, because the channel-shaped portion partial width of moulding material is too little, so, separately or the measure of removing the counterdie recessed portion will not only cause the shaped portion of passive pattern that material accurately is shaped, and cause the counterdie weakening strength, thereby can't guarantee the shaping effect of recessed portion.
In addition, for being spill with materials processing by means of the slip pattern, must make passive pattern on a quite long stroke, do linear slide, in such structure, passive pattern may not necessarily be done the slip of repeatability easily between appointed positions with enough precision, thereby be difficult to stabilized quality grade converted products.
In addition, sometimes must correct the distortion or the crushed element that occur in the product, but because the parts of automobile-such as outer panel body portions such as side vehicle body, front fender, roof, bonnet, trunk lid, door-plate and front column shell-have three-dimension curved surface or three-dimensional curve, almost be impossible so these parts are corrected.When the metal sheet product to automobile assembled, the product of distortion or distortion was difficult to match with other part.So just can't assemble out high-quality automobile body-used sheet metal structure, and the forming accuracy of metal sheet can not guarantee.
Moreover, using this slip pattern that bigger passive pattern need be set, and need pattern footstock (heal) be set being used for a certain side of counterdie of place work piece material, this will increase the area of counterdie, thereby correspondingly gain in weight and manufacturing cost.
