Description
Technical field
The utility model relates to technical field of mold, particularly a kind of blanking and drawing composite die.
Background technology
Mould is one of technological equipment important during modern industry is produced, and in the production industries such as casting, forging, punching press, plastics, rubber, glass, powder metallurgy, pottery, is used widely.In recent years, the mould industry of China has also had larger development, and mold production process and the intelligent degree of production equipment are more and more higher, has greatly improved the accuracy of manufacture, quality and the productivity ratio of mould.
Blanking and drawing substep in traditional moulds application carries out, and generally, first blank material is carried out to blanking by blanking die, then lower materials and parts is placed in cupping tool and carries out drawing processing, obtains the blank of drawing.In drawing process, blank is subject to the effect of punch drawing pressure, in the radially generation tensile stress of flange blank, tangentially produces compression stress.Under their acting in conjunction, flange deformation region material generation plastic deformation, and be constantly drawn into formation tube drawing in die.Because blanking and drawing separate machined have error, the accumulated error producing is large, is more prone to occur the phenomenon of product cracking in the time of drawing, and workpiece after drawing is easily stuck in drawing die, be difficult for taking out, reduced operating efficiency, even cause that mould damages.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of colony material and drawing good in one, workpiece surface quality, do not crease easily, operating efficiency is high and workpiece easily takes out blanking and drawing composite die.
The purpose of this utility model is achieved through the following technical solutions: a kind of blanking and drawing composite die, it comprises upper bolster, die shoe and guide pillar, upper bolster and die shoe arrange in opposite directions, guide pillar is vertically fixed on four jiaos of die shoe, top and the upper bolster of guide pillar are connected, it also comprises blanking die, drawing punch, ejection block and the compound punch of blanking drawing, the below of upper bolster is fixed with fixed head, the compound punch of blanking drawing is arranged on the center of fixed head, the compound punch of blanking drawing inside is provided with unloading block, the center of upper bolster is penetrated with knock-pin, the lower end of knock-pin is pressed on the upper surface of unloading block, blanking die is fixed on die shoe top, blanking die top is also provided with stripper, drawing punch is fixed on the center of blanking die, ejection block is sleeved on drawing punch outside, drawing punch, ejection block and the compound punch of blanking drawing enclose and form Workpiece shaping chamber, and the below of ejection block is also provided with high pressure spring.
Between described upper bolster and fixed head, be also provided with convex mould pad.
Between described die shoe and blanking die, be also provided with die backing plate.
Between described upper bolster and guide pillar, be also provided with guide pin bushing, guide pin bushing is fixed on upper bolster, and guide pillar and guide pin bushing are slidably matched.
Described high pressure spring is helium spring.
The utlity model has following advantage:
1, blanking and drawing sequence are integrated on a mould, have significantly reduced the manufacturing cost of mould, while having shortened worker, improved production efficiency.
2, blanking and drawing one-shot forming, accumulated error is little, provides pressure by helium spring, and pressure-plate-force is large, and surface of the work does not crease easily, and product quality is high.
3, in the compound punch of blanking drawing, unloading block is set, after moulding, promotes unloading block by external force, workpiece is ejected to the compound punch of blanking drawing, be difficult for getting stuck.
