Bidirectional edge folding mechanism for sheet material

Abstract

The invention belongs to the field of sheet metal part producing and machining equipment and mainly relates to a bidirectional edge folding mechanism for a sheet material. The bidirectional edge folding mechanism comprises an upper folding knife structure for downwards bending the sheet material and a lower folding knife for upwards bending the sheet material, wherein an upper folding knife (29) and a lower folding knife (30) in the upper folding knife structure and the lower folding knife structure are located above and below the machined sheet material respectively and are arranged symmetrically up and down; a lever mechanism connected with a driving part is connected with a folding knife beam; the folding knife beam drives the folding knives to do circular-arc movement by taking the fulcrum of the lever mechanism as a circle center, so as to downwards or upwards bend the sheet material. According to the bidirectional edge folding mechanism, an upper bidirectional edge folding mechanism and a lower bidirectional edge folding mechanism are used for rotatably bending the sheet material needing to be machined so as so realize that the sheet material can be bent at different angles in the two directions under the state of one-time feeding; the auxiliary time is shortened effectively and the working efficiency is improved; meanwhile, the bending and the edge folding at the different angles can be carried out at the same time, the operation is flexible and the size precision can be guaranteed.

Description

technical field [0001] The invention belongs to the field of production and processing equipment for sheet metal parts, and mainly relates to a two-way folding mechanism for sheet metal. Background technique [0002] At present, hydraulic bending machines, pneumatic flap bending machines and manual flap bending machines are used in sheet metal parts production and processing. [0003] Figure 18 Provide the schematic of existing hydraulic bending machine, universal hydraulic bending machine is made up of main parts such as frame 61, frame platform 62, folding knife beam 66, folding knife 65, lower die 63, driving oil cylinder 67. The jackknife beam 66 is in the form of a simply supported beam. The two points are on both sides of the simply supported beam, that is, the piston rods of the two drive cylinders are the fulcrums, and the cylinder body is firmly connected with the frame. Folding knife beam 66 is installed in the slide seat that frame both sides is provided with....

Problems solved by technology

In mass production, the consistency of size is difficult to control

Moreover, the labor intensity of workers is high, which is not conducive to physical and mental health.

[0010] 2. Due to the excessive auxiliary time in the production process, the production efficiency is low and the production cost increases

[0011] 3. In mass production, there are many equipments, many operators and large floor area
