A new type of online precision secondary bending forming device

Abstract

The invention discloses a novel on-line precise secondary bending formation device which comprises an upper cutting knife, a primary material pressing plate, secondary material pressing plates and a lower bending knife, wherein the lower bending knife can be used for cutting, primary bending and secondary bending simultaneously; the primary material pressing plate is arranged above the lower bending knife; an upper knife hole is formed in the primary material pressing plate; support seats are arranged on the left and right sides of the lower bending knife; the secondary material pressing plates are arranged at the tops of the support seats in such a manner that the angles between the secondary material pressing plates and vertical directions are 45 DEG C; a protrusion is formed at the top of the lower bending knife. The novel on-line precise secondary bending formation device has the advantages that twice horizontal bending can be finished continuously on a production line, so that large quantities of manpower and material resources are saved, the production efficiency is improved, the production cost is reduced, the product quality is improved, the problem of failure in meeting drawing requirements on part sizes in the prior art is solved, material rebound can be eliminated, products meeting requirements can be produced at a time, and the production efficiency is improved by 50% than that of the conventional device.

Description

technical field [0001] The invention relates to the technical field of metal product bending, in particular to a novel online precision secondary 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, and shelf products have forming requirements in both hori...

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 produced products 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, and shelf products have forming requirements in both horizontal and vertical directions, while the existing forming device can complete a horizontal bending process, and use another equipment to complete the horizontal bending process, which cannot Using one device to complete two transverse bendings at the same time, in this way, the processing efficiency is extremely low
