Abstract
The invention discloses a bending and shaping stamping die, which comprises an upper die holder, a lower die holder, a backing plate, fixed plates, an upper bending pressure plate, bending punches, a lower ejector plate, a lower bending insert and lower bending baffles, wherein the backing plate is arranged below the upper die holder; the fixed plates are arranged on the two sides of the backing plate; the upper bending pressure plate is arranged at the middle part of the backing plate; the bending punches are arranged between the upper bending pressure plate and the two fixed plates in a way of swinging a certain angle; the lower ejector plate is arranged on the lower die holder; the lower bending insert is arranged on the lower ejector plate and in a position corresponding to the upper bending pressure plate; the lower bending baffles with a certain inclination angles are arranged on the two sides of the lower ejector plate on the lower die holder; the inclination angles of the lower bending baffles are matched with swinging angles of the bending punches. According to the bending and shaping stamping die, the aim of shaping can be fulfilled during bending, so that the reject ratio of a product is lowered, and the machining cost of the product is lowered.
Description
Technical field
The present invention relates to a kind of mould structure, particularly relate to a kind of bent reshaping 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.
At present, the bending part that traditional bend punching die processing resilience is larger, often causes client to complain because bending edges spring back angle is bad, and all needs to carry out shaping again by shaping mould again to these defective products, there is the shortcoming that processing cost is high.
Summary of the invention
The object of the present invention is to provide a kind of bent reshaping diel, it has the advantages that fraction defective is low and processing cost is low, to solve in prior art for processing the problems referred to above of the diel existence of the larger bending part of resilience.
For reaching this object, the present invention by the following technical solutions:
A kind of bent reshaping diel, it comprises upper bolster, die shoe, backing plate, fixed head, upper bending pressing plate, Bending punch, lower liftout plate, lower bending insert and lower bending block, wherein, the below of described upper bolster arranges backing plate, the both sides of described backing plate are provided with fixed head, and the middle part of described backing plate is provided with bending pressing plate, can wave between described upper bending pressing plate and two fixed heads and angularly be provided with Bending punch, described die shoe is provided with lower liftout plate, on described lower liftout plate, corresponding upper bending pressing plate is provided with lower bending insert, described die shoe is arranged the lower bending block with certain angle of inclination in the both sides of described lower liftout plate, the angle of inclination of described lower bending block coordinates the swing angle of described Bending punch to arrange, and the position of corresponding lower bending insert is provided with cylinder push pedal on described die shoe, described cylinder push pedal connects cylinder.
Especially, two side roof part correspondences of described upper bending pressing plate offer draw-in groove, one side roof part of described Bending punch coordinates draw-in groove to be extended with the dop of protrusion, and the top of described Bending punch be extended with protrusion wave limited block, describedly wave the bottom that limited block is resisted against described backing plate, and its end face is circular arc.
Especially, described die shoe is fixed with the first block in the both sides correspondence of described lower liftout plate, the fixing lower bending block in inner side of described first block.
Especially, the swing angle of described Bending punch is 2 °, and the angle of inclination of corresponding described lower bending block is 2 °.
Beneficial effect of the present invention is, compared with prior art described bent reshaping diel can wave the Bending punch of certain angle and lower bending block by arranging, make Bending punch can wave certain angle in the process of bending, thus the object of shaping can be reached when bending simultaneously.Bending angle excessive or too small time, the adjustment of bending angle size can be realized by adjustment punching machine stroke height.Not only reduce the fraction defective of product, and reduce the processing cost of product.
