Abstract
The utility model provides a stamping die suitable for bending of thin plates. According to the technical scheme, the stamping die comprises a core die and a cavity die which are matched with each other. A U-shaped pressing plate is fixed on the cavity die. The stamping die is characterized in that the edges of the cavity die are provided with positioning pins which are used for fixing the thin plates; the U-shaped pressing plate and the core die are provided with pin holes which are corresponding to the positioning pins; a protruding angle which protrudes outward is fixed on the working surface of the core die; the protruding angle forms the outer protrusion portion of the core die; the cavity die is provided with a protruding angle groove which is corresponding to the protruding angle. According to the stamping die suitable for the bending of the thin plates, the structural design is simple, the operation is convenient, the production efficiency is high, the bending forming can be performed on the thin plate parts which need to be bent rapidly and flexibly, the angle of the protruding angle can be designed according to the production need and accordingly the different bending angles of thin plate parts can be obtained, and the commonality is strong.
Description
Technical field
The utility model relates to disposable diel, especially a kind of diel that is applicable to light sheet bending.
Background technology
At present, how growing along with economy, used relatively reasonable cost effectively, raises the efficiency and become the subject matter that industry-by-industry is faced; In machinery production process, because often can running into, structure, the shape difference of produced product slim sheet material need to be folded to the situation of certain angle.In prior art, the bender generally using is when the part bending to more complicated, on bender, bending difficulty even can not operate, and this main equipment operating procedure is complicated, cost is high, when equipment occur to damage, later maintenance program is complicated, thereby is not suitable for the little and complex parts bending of thin plate; And at folding, during thin plate, conventionally use hammer to beat sheet material and make its shape that reaches expection at present, but this method inconvenient operation, angle is inaccurate, and the place of beaing has the good looking appearance that indenture affects thin plate conventionally.This is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme that is applicable to the diel of light sheet bending, this scheme structural design is simple, easy to operate, production efficiency is high, can fast and flexible will need the sheet part of bending to carry out bending and molding, the angle that designs salient angle according to the needs of producing is to obtain the sheet part of different bending angles, highly versatile.
This programme is achieved by the following technical measures: a kind of diel that is applicable to light sheet bending, comprise the punch and the die that cooperatively interact, on described die, be fixed with U-shaped pressing plate, the feature of this programme is: the edge of described die is provided with the alignment pin for splint fixation, and described U-shaped pressing plate is provided with the pin-and-hole corresponding with alignment pin with punch; On the working face of described punch, be fixed with outwardly salient angle, this salient angle forms the evagination part of punch, and described die is provided with the salient angle groove corresponding with salient angle.
The concrete feature of this programme is: the angle of described salient angle is 70 °-90 °.
Two inclined-planes of described salient angle groove and the angle between horizontal plane are respectively 120 ° and 140 °.
With bolts between described U-shaped pressing plate and described die.
The base of described die is welded with base.
Described pin-and-hole be shaped as circle or polygon, and described alignment pin adopts is cylindrical positioning pins or diamond positioning pin.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this programme comprises punch and the die cooperatively interacting, and is fixed with U-shaped pressing plate on described die, U-shaped pressing plate can be in mold work process better retaining element, prevent part position change, to improve precision; The edge of described die is provided with the alignment pin for splint fixation, and described U-shaped pressing plate is provided with the pin-and-hole corresponding with alignment pin with punch; On the working face of described punch, be fixed with outwardly salient angle, this salient angle forms the evagination part of punch, and described die is provided with the salient angle groove corresponding with salient angle.This programme is simple in structure, flexible and convenient operation, and energy is disposable, and to sheet part bending and molding, production efficiency is high, designs the angle of salient angle to obtain the sheet part of different bending angles according to the needs of actual production, thereby highly versatile; Compare with adopting large-scale bending equipment, greatly reduced to produce and dropped into, there is very strong practical significance, be applicable to promoting the use of.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model die.
Fig. 2 is the structural representation of the utility model punch.
In figure, 1 is die, and 2 is salient angle groove, and 3 is alignment pin, and 4 is bolt, and 5 is punch, and 6 is pin-and-hole, and 7 is salient angle, and 8 is die holder, and 9 is U-shaped pressing plate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, a kind of diel that is applicable to thin plate described in this programme, comprise the punch 5 and the die 1 that cooperatively interact, on described die 1, be fixed with U-shaped pressing plate 9, the edge of described die 1 is provided with the alignment pin 3 for splint fixation, and described U-shaped pressing plate 9 and punch 5 are provided with the pin-and-hole corresponding with alignment pin 36; On the working face of described punch 5, be fixed with outwardly salient angle 7, this salient angle 7 forms the evagination part of punch 5, described die 1 is provided with the salient angle corresponding with salient angle 77 grooves, described pin-and-hole 6 be shaped as circle or rhombus, and described alignment pin 3 adopts is cylindrical positioning pins or diamond positioning pin.
In practical work process, edge sheet part with holes is placed on U-shaped pressing plate 9 and is fixed, punch 5 is placed on die 1, make the pin-and-hole 6 of punch 5 aim at the alignment pin 3 of die 1, then use mini-plant (stamping machine) to carry out punching press to punch 5, complete bending action; The base of die 1 is welded with die holder 8, and the work area of the Area Ratio die 1 of die holder 8 is large, guarantees that mould fixation is reliable in punching course, prevents from occurring having improved the quality of production by substandard products because of rocking of mould.
