Description

The taper flanging Drawing Die of Pneumatic demould
Technical field
The utility model relates to Drawing Die field, is specifically related to the taper flanging Drawing Die of a kind of Pneumatic demould.
Background technology
Press tool is applied very extensive in modern industry is produced, and is one of the important means of five metals processing. Press tool is in actual use, it is necessary to put material, discharging, puts that material is general adopts craft or automatic mechanism realizes, though and discharging has automatic discharger at present, but actual conventional be still that craft discharging is in the majority, expend time in length, and discharging demoulding efficiency is low. Simultaneously, it mostly is to arrange scalable cylinder in die cavity bottom surface because of existing automatization discharging mechanism, contacts material by cylinder, boosted, cylinder and storeroom are hard contact, easily leave mark at material outside surface or draw in the process of jack-up and hinder material surface. And carrying out workpiece, when punching press is drawn dark, the limit of blank is carried out horizontal flanging, such flanging, to the stable deficiency of blank, makes blank easy unstability in drawing process, and the workpiece surface after drawing and forming is seriously wrinkling, and surface quality is low. So, the present deep draw mould that draws is not well positioned to meet the needs of actual production, particularly draw dark operation to needing and material surface flatness or clean and tidy degree are required higher product, have print, surface wrinkling or draw wound appearance time, often need material surface compensates formula processing again, waste time and energy, reduce working (machining) efficiency low.
Practical novel content
The utility model is intended to provide the taper flanging Drawing Die of Pneumatic demould, to alleviate the wrinkling of drawing and forming workpiece, it is to increase the demoulding efficiency of drawing and forming.
For achieving the above object, basic technology scheme of the present utility model is as follows: the taper flanging Drawing Die of Pneumatic demould, comprises top plate, lower template, punch, die, flanging circle. Described die is fixed on the lower end of top plate, and described punch is fixed on the upper end of lower template, and described punch and die are oppositely arranged. The outside of described punch is provided with the flanging circle that upper end is taper, and the lower end of described die mates mutually with the upper end of flanging circle. Being provided with horizontal air flue in described top plate, one end of described air flue is positioned at top plate, and the other end of air flue is positioned at the outer of top plate and is provided with internal thread; The bottom of described die be provided with some erect to pore, described pore is connected with air flue.
The principle of this scheme: during operation, it would be desirable to draw dark workpiece to buckle and be placed on punch, orders about top plate by drive units such as hydropress and die moves downward, and die coordinates with flanging circle to be pushed down workpiece edge, and die coordinates with punch and drawn deeply by workpiece. Draw after deeply completing, the tracheae of the inflation mechanisms such as air pump is connected with top plate by the internal thread on air flue, punch is filled with pressurized air by inflation mechanism after being separated with die in air flue, and pressurized air enters die by pore makes workpiece be separated the demoulding with die. Taper is arranged in the upper end of flanging circle, when drawing dark workpiece, workpiece is stretched by punch and die like this, workpiece residue part is attached on flanging circle under stress and evenly enters die under the extruding of punch, distortion position has bigger anti-unstability ability, reduce wrinkling trend, change the condition of deep-drawing deformation, after drawing and forming, wrinkle can not be formed at workpiece surface. Air flue is set in top plate, the pore being connected with air flue is set in die, by being filled with pressurized air in air flue, workpiece can be come off in die after shaping, realize pneumatic automatic demoulding, do not need manually to beat mould and carry out the demoulding, decrease the damage to mould, decrease artificial stripping operation, it is to increase the efficiency of the demoulding.
Preferred version one, based on a kind of improvement of scheme, four corners of the lower end of described top plate are provided with four guide pin bushings, the upper end of described lower template is provided with four relative with guide pin bushing guide pillar, and the top of guide pillar extend in guide pin bushing. Guide pin bushing and guide pillar cooperation are set like this, it is possible to for top plate and die provide stable guiding, prevent from producing between punch, die skew, affect processing quality.
Preferred version two, preferably a kind of improvement of, is provided with, between described guide pin bushing and lower template, the return spring being socketed on guide pillar. Arrange return spring can punch and die automatically be resetted after punching press completes, shock absorption can also be provided during punching press, prevent that die lowering speed is too fast to be damaged punch.
Preferred version two, preferably a kind of improvement of, the upper end of described lower template is provided with groove, and described punch is fixed by screws in groove. Arrange like this and it is possible to prevent punch and produces to offset and affect the shaping of rectangular cover in lower template, make the fixing more stable, firm of punch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: top plate 1, air flue 2, pore 3, die 4, guide pin bushing 5, guide pillar 6, return spring 7, lower template 8, screw 9, flanging circle 10, punch 11, internal thread 12.
Embodiment is substantially as shown in Figure 1: the taper flanging Drawing Die of Pneumatic demould, comprises top plate 1, lower template 8, punch 11, die 4, flanging circle 10. Described die 4 is fixed on the lower end of top plate 1, and the upper end of described lower template 8 is provided with groove, and described punch 11 is fixed in groove by screw 9, and described punch 11 and die 4 are oppositely arranged. The outside of described punch 11 is provided with the flanging circle 10 that upper end is taper, and the lower end of described die 4 mates mutually with the upper end of flanging circle 10. Being provided with horizontal air flue 2 in described top plate 1, one end of described air flue 2 is positioned at top plate 1, and the other end of air flue 2 is positioned at the outer of top plate 1 and is provided with internal thread 12; The bottom of described die 4 be provided with some erect to pore 3, described pore 3 is connected with air flue 2.
