Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2, 3, 4 and 5, a rear triangular jaw hemming die comprises: lower module 200, fixing base 400, hem punching press piece 500, jack catch punching press piece 600, first piece 700 and the second of promoting promote piece 800, this mould can promote piece 800 through first piece 500 and the second of promoting and drive hem punching press piece 500 and jack catch punching press piece 600 respectively, and the jack catch position outward appearance is out of shape when avoiding the back triangle to take shape.
It is worth explaining here that, in current mould, the ejector pad promotes the hem piece for the hem piece punching press work piece rolls over the jack catch in the hem, but in actual forming process, jack catch shaping terrace die can contact the product at first, causes the jack catch root to produce great wavy sunken, and the jack catch of rolling over earlier can cause the product section unstable, so actual effect is relatively poor.
In order to overcome the defects caused by simultaneous edge folding and claw folding or claw folding in advance, the edge folding stamping block 500 and the claw stamping block 600 are arranged into a split structure, edge folding is performed firstly, then the claw is folded, and the method is not realized by two working procedures, but the rear triangular stamping is formed at one time by a method of arranging the sequence in one working procedure.
Preferably, the fixing seat 400 is a slope structure or a plane structure, and the fixing seat 400 is located beside the lower module 200, and the hemming punch 500 is disposed on the fixing seat 400 and can slide towards the lower module 200.
Particularly, hem punching press piece 500 can incline decurrent punching press down module 200, when hem punching press piece 500 contradicts on treating the shaping product, can not only form earlier out the hem, can also fix and treat the shaping product, the product warp when can preventing to roll over the jack catch like this.
The jaw press block 600 is arranged on the flanging press block 500 and can slide towards the lower module 200, the distance between the front end face of the jaw press block and the lower module is larger than the distance between the front end face of the flanging press block and the lower module, particularly, the jaw press block 600 is arranged at the front end of the flanging press block 500 in a slidable manner, so that the front end of the flanging press block 500 is closer to the lower module, when the flanging press block 500 abuts against a product, a product to be formed is abutted by the flanging press block 500, so that the effect of clamping the product is achieved, and on the condition that the flanging press block 500 abuts against the product, the jaw press block 600 continues to press the product, so that a jaw is pressed out.
The lower module 200 is provided with a product 100 to be formed, the product 100 to be formed (hereinafter referred to as a product) is placed on the lower module 200 to wait for flanging and clamping jaws, the fixing seat is positioned on the side of the lower module and is close to the lower module, and the first pushing block 700 pushes the flanging stamping block 500 to abut on the product 100 to be formed so as to form a flanging, so that deformation and various defects in appearance can not be caused due to the fact that the flanging is performed firstly, and a clamping and fixing effect can be achieved.
Then the second pushing block 800 pushes the jaw press block 600 to be abutted to the product 100 to be formed so as to form a jaw, so that the jaw is formed without dividing into two processes, the jaw press block 600 can be prevented from contacting the product during edge folding, the product is pressed by the jaw press block 600 after edge folding, the edge folding can be performed in one process, then the jaw is pressed, the product appearance deformation is avoided, and the product quality is greatly improved
As shown in fig. 1, in addition to the above embodiment, the rear triangular jaw hemming die further includes an upper die block 300, the upper die block 300 is movable up and down, and the upper die block 300 is located above the lower die block 200 and the fixing base 400 and is movable toward the lower die block 200 and the fixing base 400.
