Embodiment 1

[0024] see Figure 1 to Figure 2 , the figure shows a rapid bending and forming device for multi-angle sheet metal parts provided by Embodiment 1 of the present invention. First, a mold is set up, which includes an upper mold 1 and a lower mold 2. The upper mold 1 includes two hinged parts The first template 11 of the first template 11, the hinged ends 111 of two first templates 11 are connected to the end of the first elevating mechanism 3, and the first elevating mechanism 3 includes the first guide rail 31, the second guide rail 32 and the motor 33, the first guide rail 31 The first slider 311 is slidably installed on the upper side, and the second slider 321 is slidably installed on the second guide rail 32. The ends of the two first templates 11 are respectively connected to the first slider 311 and the second slider through the transmission rod assembly 12. The block 321, the first slide block 311 and the second slide block 321 all slide under the drive of the motor 33, ...

Embodiment 2

[0029] see Figure 1 to Figure 2 , the figure shows a rapid bending and forming device for multi-angle sheet metal parts provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements The upper mold 1 includes two first templates 11 hinged to each other, the hinged ends 111 of the two first templates 11 are connected to the end of the first lifting mechanism 3, and the first lifting mechanism 3 includes a first guide rail 31, a second guide rail 32 and a motor 33, the first slide block 311 is slidably installed on the first guide rail 31, the second slide block 321 is slidably installed on the second guide rail 32, and the ends of the two first templates 11 are respectively connected to the drive plate assembly 12. The first sliding block 311 and the second sliding block 321 have higher strength than the driving rod as compared with the first embodiment, and can...

Embodiment 3

[0031] see Figure 1 to Figure 2 , the figure shows a rapid bending and forming device for multi-angle sheet metal parts provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements The lower mold 2 includes two second templates 21 hinged to each other, the second template 21 is installed on the second lifting mechanism 4, the upper surface of the lower mold 2 is equipped with an ejection mechanism, and the ejection mechanism includes two elastically connected plates, It is tightly attached to the surface of the lower mold 2 under the pressing action of the upper mold 1. After the sheet metal part is formed, the upper mold 1 is released, and the two elastically connected plates return to their original shape under the action of the elastic force, and then the formed sheet metal The top of the piece is separated from the lower mold 2, which is convenient for th...

Abstract

The invention provides a rapid bending forming device for multi-angle sheet metal parts. The rapid bending forming device is provided with an upper mold and a lower mold at first; the upper mold comprises two first mold plates hinged to each other, a first lifting mechanism comprises a first guide track, a second guide track and a motor, a first sliding block is slidably mounted on the first guidetrack, a second sliding block is slidably mounted on the second guide track, the ends of the two first mold plates are respectively connected with the first sliding block and the second sliding blockthrough transmission rod assemblies, and the first sliding block and the second sliding block slide under the driving effect of the motor; and the lower mold comprises two second mold plates hinged to each other, and the second mold plates are driven by a second lifting mechanism to rotate. Compared with the prior art, the rapid bending forming device has the advantages that the bending angle ofthe molds can be adjusted accurately to rapidly form sheet metal parts bent at various angles. Meanwhile, the invention also provides a rapid bending forming method of the multi-angle sheet metal parts, and the rapid bending forming method involves the bending forming principle of the device.

Description

technical field [0001] The invention relates to sheet metal, in particular to a rapid bending forming device and a forming method for multi-angle sheet metal parts. Background technique [0002] Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is the same The thickness of the parts is the same, and the products processed by the sheet metal industry are called sheet metal parts. The sheet metal parts referred to by different industries are generally different, and they are mostly used for assembly. [0003] Sheet metal parts are the product of sheet metal technology. Due to the different needs of the market, the bending angles of sheet metal parts are often different. At present, most of these sheet metal parts in the market adopt a production method of one piece corresponding to o...
