Description

A kind of once-forming bending die of frame section
Technical field
It the utility model is related to a kind of once-forming bending die of frame section.
Background technology
At present, the existing bending of simple frame section time one is i.e. formable, but due to no material pressing device, blank during press-bending Easily slide, be only applicable to less demanding part.
Utility model content
Purpose:In order to overcome the deficiencies in the prior art, it is once-forming curved that the utility model provides a kind of frame section Qu Mo.
Technical scheme:In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of once-forming bending die of frame section, it is characterised in that:Including upper bolster, spring, the first punch-pin, centering block, pressure Block, horizontal punch-pin, punch-pin, cavity plate, die shoe;
The top of first punch-pin is flexibly connected with upper bolster, and the bottom of the first punch-pin is located at the centre position of die shoe, under From punch-pin, cavity plate, the first punch-pin is arranged in order inside outside on die holder, horizontal punch-pin is arranged on the top of punch-pin and cavity plate, laterally One end of punch-pin is in contact with the top working face of punch-pin, other end to the side of the first punch-pin,
Spring is set between the top middle portion and upper bolster of the first punch-pin, and the both sides of upper bolster are provided with briquetting, and first is convex The side of mould is provided with centering block, when briquetting moves down, promotes centering block to push.
Preferably, the once-forming bending die of described frame section, it is characterised in that:Opened in the middle part of the die shoe Provided with the through hole passed through for push rod.
Preferably, the once-forming bending die of described frame section, it is characterised in that:Also include top plate, roof water The flat position being arranged between two punch-pin, it is corresponding with the working face of the first punch-pin.
Preferably, the once-forming bending die of described frame section, it is characterised in that:The working face of the punch-pin is The arc surface of a quarter, it is forced to do transverse movement for promoting working face of the horizontal punch-pin along punch-pin to move.
Preferably, the once-forming bending die of described frame section, it is characterised in that:The upper bolster and first convex Lead is additionally provided between mould.
Preferably, the once-forming bending die of described frame section, it is characterised in that:The bottom of the briquetting is also set Adjustment block is equipped with, has corrective action to bool.
Preferably, the once-forming bending die of described frame section, it is characterised in that:The working face of the centering block is Planar structure.
Beneficial effect:The once-forming bending die of a kind of frame section provided by the utility model, there is the frame of top plate and alignment pin The once-forming bending die of shape part, it can effectively prevent the skew of blank.The effect of top plate overcomes horizontal direction between upper and lower mould Offsetting power, while push rod is also oriented to for top plate, prevents its play.Blank is positioned on cavity plate and positioned, and when upper mould is descending, first is convex Blank is bent to U-shaped by mould.Upper mould is continued traveling downwardly, and spring is compressed, and working face of the horizontal punch-pin along punch-pin moves and be forced to do Transverse movement, bend c, b circular arc.Then briquetting pressure centering block, a circular arcs are bent, stroke is ended has corrective action to bool.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:Upper bolster 1, spring 2, the first punch-pin 3, centering block 4, briquetting 5, adjustment block 6, horizontal punch-pin 7, punch-pin 8, cavity plate 9th, die shoe 10.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of once-forming bending die of frame section, including upper bolster 1, spring 2, the first punch-pin 3, centering block 4, Briquetting 5, adjustment block 6, horizontal punch-pin 7, punch-pin 8, cavity plate 9, die shoe 10.
It is arranged in order punch-pin 8, cavity plate 9, the first punch-pin 3 on die shoe 10, horizontal punch-pin 7 is arranged on punch-pin 8 and cavity plate 9 Top, one end of horizontal punch-pin 7 are in contact with the top working face of punch-pin 8, other end to the side of the first punch-pin 3,
The bottom of first punch-pin 3 is located at the centre position of die shoe 10, and top and the activity of upper bolster 1 of the first punch-pin 3 connect Connect, spring 2 is set between the top middle portion and upper bolster 1 of first punch-pin 3, the both sides of upper bolster 1 are provided with briquetting 5, and first is convex The side of mould 3 is provided with centering block 4, when briquetting 5 moves down, promotes centering block 4 to push.
The through hole passed through for push rod is offered in the middle part of the die shoe.
The once-forming bending die of described frame section, it is characterised in that:Also include top plate, top plate be horizontally set on two it is convex Position between mould, it is corresponding with the working face of the first punch-pin.
