Tailored welded blank thermoforming die

Abstract

The invention provides a hot forming die and relates to the technical field of material forming. The hot forming die comprises a press machine template, a die holder, suspension modules and elastic parts. The suspension modules include the first suspension module and the second suspension module. A die cavity used for containing a plate material is formed between the press machine template and thefirst and second suspension modules. The elastic parts are used for acting on the end, far away from the press machine template, of the suspension modules to enable the first suspension module and the second suspension module to be capable of floating up and down relative to the die holder so as to make up the material thickness deviation of the plate material and enable the die to be attached tothe plate material. Plate parts produced through multiple cavities can be cooled under the uniform conditions to achieve the optimum production efficiency and protect die inserts. The technical problems that in the prior art, the production efficiency is limited, the yield is low, part of die inserts are damaged, the service life is shortened and the cost is increased are alleviated. The production efficiency is improved. The defective rate is lowered. The service life of the die inserts is prolonged.

Description

technical field [0001] The invention relates to the technical field of material forming, in particular to a tailor welded blank thermoforming die. Background technique [0002] Laser tailor-welded blanks use laser energy to automatically assemble and weld steel, stainless steel, and aluminum alloys of different materials, thicknesses, and coatings to form a whole sheet, profile, sandwich panel, etc., to meet Parts have different requirements for material properties, and realize lightweight equipment with the lightest weight, optimal structure and best performance. [0003] The production mold of laser tailor welded blank in the prior art, such as figure 1 As shown, the material thickness of area A of tailor welded blank takes the lower limit of negative tolerance, and the upper limit of positive tolerance of area B of tailor welded blank. The gap between area A of the blank and the mold cavity in the mold cavity is 0.1mm. Theoretically, area A and area B share the force o...
