Problems solved by technology

During forming, because the relative sliding between the workpiece and the folding knife 2 is extremely large, the surface of the formed product is easily damaged due to high friction, and it is easy to sink in the vicinity of the bending point, resulting in forming defects.
In addition, when the existing bending forming device 1 is applied to a product with a large bending height, it is very easy to cause deformation on both sides of the product due to height vibration during the forming process.
Moreover, the folding knife 2 of the existing bending forming device 1 is close to the surface of the workpiece, so it cannot be tilted inward, otherwise the product will be stuck and the product cannot be stripped out. Therefore, the existing bending forming device 1 cannot form Products with bending angle less than 90 degrees

Embodiment Construction

[0016] Please refer to FIG. 2 , the bending forming device 10 of the present invention is mainly composed of a folding knife 20 , a punching plate 30 , a supporting plate 40 and a turning plate 50 .

[0017] The beating plate 30 is approximately in the shape of a cuboid and is located inside the jackknife 20. There is a certain distance between the beating plate 30 and the jackknife 20, which is roughly equal to the thickness of the turning plate 50 and can be adjusted and controlled by the supporting plate 40 to be suitable for different applications. thickness of the flap 50.

[0018] Please refer to image 3 A supporting section 42 , an abutting section 44 and a slope section 46 are sequentially formed on the top of the supporting plate 40 from inside to outside. A countersunk screw hole 48 is formed on the supporting section 42 , and a screw (not marked on the figure) can pass through the screw hole 48 to fix the supporting plate 40 and the punching plate 30 together. Th...

Abstract

The present invention relates to a bending-forming equipment and its method. Said equipment mainly consists of bending blade, striking plate, support plate and turning plate, and its bending-forming process includes the following steps: 1. opening die; horizontally placing the turning plate on the top surface of benidng blade, then horizontally placing the workpiece on the striking plate and turning plate; 2. closing die; using punching head to strike the workpiece and drive striking plate to make it move downward, at the same time drive turning plate to make it turn over, and after the turning plate is slid into a certain distance between the striking plate and bending blade, the workpiece is bent and formed; and 3. opening die; under the action of elastic force the striking plate is moved upward, the turning plate also is moved upward, under the action of g-force of turning plate said turning plate can be turned over and horizontally placed on the top surface of bending blade.

Description

technical field [0001] The invention relates to a bending and bending device and method, in particular to a bending and forming that can ensure the structural quality and dimensional accuracy of the formed product, and the bending height of the formed product is large and the bending angle can be less than 90 degrees Devices and methods. Background technique [0002] Existing bending forming device 1 can refer to figure 1 , which mainly includes a jackknife 2 and a punching plate 3 that slide relative to each other in translation. During forming, because the relative sliding between the workpiece and the folding knife 2 is extremely large, the surface of the formed product is easily damaged due to high friction, and it is easy to sink in the vicinity of the bending point to generate forming defects. In addition, when the existing bending and forming device 1 is applied to a product with a large bending height, it is very easy to deform the sides of the product due to heigh...
