Description
Technical field
The present invention relates to a kind of once-forming bending die of frame section.
Background technology
At present, an existing simple frame section time bending is formable, but due to no material pressing device, blank during press-bending
Easily slide, be only applicable to less demanding part.
The content of the invention
Purpose：In order to overcome the deficiencies in the prior art, the present invention provides a kind of once-forming bending die of frame section.
Technical scheme：In order to solve the above technical problems, the technical solution adopted by the present invention 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, briquetting, horizontal stroke
To 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, die shoe
On from punch-pin, cavity plate, the first punch-pin is arranged in order inside outside, horizontal punch-pin is arranged on the top of punch-pin and cavity plate, horizontal punch-pin
One end be 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, the first punch-pin
Side is provided with centering block, when briquetting is moved down, and 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, the working face with the first punch-pin is corresponding.
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, 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 that the present invention is provided, there is the frame section of top plate and alignment pin
Once-forming bending die, can effectively prevent the skew of blank.The effect of top plate is the offsetting for overcoming horizontal direction between upper and lower mould
Power, while push rod is also oriented to for top plate, prevents its play.Blank is positioned on cavity plate and positioned, when upper mould is descending, and the first punch-pin will
Blank bends to U-shaped.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 direction
Motion, bends c, b circular arc.Then briquetting pressure centering block, bends a circular arcs, stroke is ended has corrective action to bool.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
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
