Embodiment 1

[0044] Embodiment 1, the present embodiment is a kind of such as figure 1 , figure 2 The deep-drawing and thinning hole-drawing process of the product shown, the structural characteristics of this product are: the material thickness is 2mm SPCC cold-rolled steel plate 1, the outer diameter of the deep-drawing hole 2 is φ9+0 / -0.3mm, and the height of the hole wall 3 is 9±0.5mm, the outer diameter of the product is φ46±0.1mm, and 3 drawing and thinning holes are processed on the circumferential position of φ33, and the evacuation positions are evenly distributed, smooth and without obvious steps4. Due to the limited size of the product, it is impossible to use the material storage shrinkage cavity deep drawing process, and the material can only be deeply deformed and extruded within a limited size range. The deformation far exceeds the deformable range of the material itself. It belongs to the cold stamping extrusion deformation process.

Abstract

The invention discloses a thinning extrusion drawing process adopted in the moulding of a force output plate product and a force output plate progressive die thereof. The thinning extrusion drawing process comprises processes of drawing, extrusion, end surface moulding, blanking, and the like. The force output plate progressive die comprises a drawing device for drawing a material belt and also comprises a punching device, a multi-thinning extrusion device, a cylindrical end surface moulding device and a blanking delivery plate. By combining the processes of drawing, extrusion, end surface moulding, blanking, and the like in a die, compared with the traditional processing way realized by adopting a single procedure and a plurality of dies, the technical scheme of the invention greatly improves the productivity and is suitable for mass production. In addition, the invention also prevents a precision error brought by shifting workpiece blanks among different stations, therefore, the processing precision is higher, and the quality stability is better.

Description

technical field [0001] The invention relates to a stamping process, in particular to a cold stamping extrusion deformation process and a mold. The process completes the punching of metal sheet materials. Background technique [0002] Usually, the deformation of materials has certain conditions, and the deformation under different conditions plays a crucial role in whether the product structure we need can be achieved in the end. Therefore, the arrangement of the process and the precision of the mold parts become the key. [0003] Stamping is a processing method that uses a press and external equipment to apply pressure to a plate through a mold to obtain parts of a certain shape and size. Stamping is a kind of processing method widely used in production, mainly used for the processing of metal thin sheet parts. [0004] At present, the punching of sheet metal parts is realized by the storage shrinkage cavity deep drawing process. However, the storage shrinkage cavity deep d...
