Problems solved by technology

Due to the springback phenomenon of all steel materials, the traditional bending forming device cannot eliminate the springback of the bending angle, so that the products produced cannot meet the requirements of the drawings, and secondary processing is required to meet our requirements. This process costs a lot of money human and material resources, the efficiency is extremely low

Abstract

The invention discloses a novel online precise bending forming device. The novel online precise bending forming device comprises a cut-off upper cutter and a bending lower cutter. A fixed top plate is arranged on the top of the cut-off upper cutter. Material pressing plates are arranged on the left side and the right side of the cut-off upper cutter in parallel. Positioning plates are arranged on the outer sides of the material pressing plates. A pressing springback cutter is arranged between the material pressing plates. A cutter groove is formed in the middle of the pressing springback cutter. The cut-off upper cutter penetrates the cutter groove. An upper cutter hole is formed in the middle of the bending lower cutter. The novel online precise bending forming device has the beneficial effects that the pressing springback cutter is arranged between the left material pressing plate and the right material pressing plate, and an inclined face is machined at the lower end of the pressing springback cutter; the pressing springback cutter is pressed downwards by a certain distance after the bending lower cutter finishes bending and returns; and a metal workpiece is pressed till the bending angle is smaller than 90 degrees, and therefore springback of materials is eliminated. The press-down amount of the pressing springback cutter can be regulated according to the springback condition of the materials, and therefore the bending angle can be accurately controlled, the angle can meet the requirement of drawings after bending springback is conducted, and the production efficiency is improved by 30% compared with the efficiency of an original production method.

Description

technical field [0001] The invention relates to the technical field of metal product bending, in particular to a novel online precision bending forming device. Background technique [0002] A bending machine is a machine that can bend thin plates. When processing parts, some parts need to be bent into a certain angle. Bending parts is usually done by a bending machine. During the use of the bending machine, the thin plate to be bent is placed on the workbench, and the bending upper die is downward, and the thin plate is bent together with the bending lower die. Due to the springback phenomenon of all steel materials, the traditional bending forming device cannot eliminate the springback of the bending angle, so that the products produced cannot meet the requirements of the drawings, and secondary processing is required to meet our requirements. This process costs a lot of money human and material resources, the efficiency is extremely low. Contents of the invention [00...
