Description
Technical field
The utility model relates to diel, particularly relates to the one upwards cupping tool in diel.
Background technology
Diel is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.
Drawing (also known as drawing) utilizes Drawing Die under the pressure effect of forcing press, plate blank or hollow process part processing made the processing method of open hollow part.It is one of punching press basic working procedure, be widely used in the production of the various industrial departments such as automobile, electronics, commodity, instrument, aerospace, not only rotating body parts can be processed, also can process box-shaped part and other complex-shaped thin-walled parts, not ironing and ironing can be divided into.Part after the former drawing and forming, the wall thickness of its each several part is substantially constant compared with the blank before drawing; Part after the latter's drawing and forming, its wall thickness has significantly thinning compared with the blank before drawing, this thinning be product requirement, the feature that it is base thickness that part presents, wall is thin.In actual production, applying more is not ironing.This chapter introduces not thinning deep-drawing technique and Design of Dies.
The mould that drawing uses is Drawing Die.Drawing Die structure is relatively simple, and compare with blanking die, working portion has larger fillet, and surface quality requirements is high, and clearance between matrix and punch is slightly larger than sheet thickness.
At present, existing cupping tool is in drawing process, and product there will be wrinkle in U-shaped inversion section, affects the surface quality of product.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of product there will not be wrinkle upwards cupping tool in U-shaped inversion section.
The utility model provides one upwards cupping tool, comprise patrix, counterdie and journey stop gear, described patrix comprises upper bolster and die, described die is arranged on described upper bolster, described counterdie comprises die shoe, punch retainer and punch, described punch retainer is arranged on described die shoe, described punch is arranged on described punch retainer, described journey stop gear comprises stroke limit plate, spring and guide pillar, one end of described guide pillar is connected with described die shoe, described guide pillar and described die shoe are moving sets, the other end of described guide pillar is fixedly connected with described stroke limit plate, described spring housing is located on described guide pillar, described spring clip is located at described stroke limit plate, between die shoe, described stroke limit plate is provided with dodges through hole, through hole is dodged described in described punch passes, the described aperture place dodging through hole is provided with the limited impression controlling deformation of products amount.
As further improvement of the utility model, described limited impression is positioned at the one end near described die.
As further improvement of the utility model, described die is arranged in described limited impression.
As further improvement of the utility model, the internal diameter of described limited impression is greater than the external diameter of described die.
As further improvement of the utility model, described upper bolster is provided with ejector beam, and described ejector beam and described upper bolster are moving sets, and described ejector beam is arranged in the drawing die cavity of described die.
As further improvement of the utility model, described ejector beam is connected with liftout slide block, and described liftout slide block is arranged in the drawing die cavity of described die.
As further improvement of the utility model, described upper bolster is connected with die shank.
As further improvement of the utility model, described limited impression is cylindric.
The beneficial effects of the utility model are: by such scheme, on the one hand, by traditional downward drawing is improved to upwards drawing; On the other hand, limited the drawing stroke of die, punch by stroke limit plate, controlled the deflection of product by limited impression, thus effectively prevent wrinkle appears in product defect in U-shaped inversion section.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of upwards cupping tool of the utility model.
Detailed description of the invention
To illustrate below in conjunction with accompanying drawing and detailed description of the invention further illustrates the utility model.
Drawing reference numeral in Fig. 1 is: die shank 1; Upper bolster 2; Die 3; Ejector beam 4; Ejection slider 5; Die shoe 6; Punch retainer 7; Punch 8; Stroke limit plate 9; Spring 10; Guide pillar 11; Limited impression 12.
As shown in Figure 1, one is cupping tool upwards, comprise patrix, counterdie and journey stop gear, described patrix comprises upper bolster 2 and die 3, described die 3 is arranged on described upper bolster 2, described counterdie comprises die shoe 6, punch retainer 7 and punch 8, described punch retainer 7 is arranged on described die shoe 6, described punch 8 is arranged on described punch retainer 7, described journey stop gear comprises stroke limit plate 9, spring 10 and guide pillar 11, one end of described guide pillar 11 is connected with described die shoe 6, described guide pillar 11 is moving sets with described die shoe 6, the other end of described guide pillar 11 is fixedly connected with described stroke limit plate 9, described spring 10 is set on described guide pillar 11, described spring 10 is folded in described stroke limit plate 9, between die shoe 6, described stroke limit plate 9 is provided with dodges through hole, through hole is dodged described in described punch 8 passes, the described aperture place dodging through hole is provided with the limited impression 12 controlling deformation of products amount.
