Plate bending forming process

Abstract

The invention relates to the technical field of plate bending forming, in particular to a plate bending forming process. The plate bending forming process includes the following steps that S1, cuttingand blanking are carried out, and a plate is cut for blanking according to the process required dimensions; S2, plate bending is carried out, a plate bending machine with a quick positioning mechanism is used for bending the plate cut in the first step, and the quick positioning mechanism of the plate bending machine makes the connecting gap positions of the two ends of the bent plate be arrangedvertically upwards; S3, gap shrinkage is carried out, and the two ends of the bent plate are in precise contact by means of a gap shrinkage mechanism arranged on the plate bending machine; S4, welding is carried out, a laser welding mechanism is installed over the plate bending machine, and the laser welding mechanism is utilized to carry out laser welding at the joints of the two ends of the bent plate; and S5, discharging is carried out after the formed barrel is obtained. The plate bending forming process is ingenious in concept and high in practicability, through the cooperation effect ofthe gap shrinkage mechanism, the quick positioning mechanism and the welding mechanism, the formed barrel can be subjected to quick positioning, gap shrinkage and then rapid welding, and the plate bending forming process is wide in application range and suitable for use and popularization.

Description

technical field [0001] The invention relates to the technical field of coil forming, in particular to a coil forming process. Background technique [0002] The plate rolling machine is a kind of equipment that uses work rolls to bend and form the sheet material. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate rolling machine is through hydraulic pressure. Force, mechanical force and other external forces make the work rolls move, so that the plate is bent or rolled into shape. According to the rotation and position changes of the work rolls of different shapes, oval parts, arc parts, and cylindrical parts can be processed. parts etc. [0003] For the coil forming of the thin plate, because the thin plate has a certain degree of elasticity, when the thin plate is rolled and formed, the two ends of the thin plate are not easy to align, and it is easy to shake, an...

Problems solved by technology

[0003] For the coil forming of the thin plate, because the thin plate has a certain degree of elasticity, when the thin plate is rolled and formed, the two ends of the thin plate are not easy to align, and it is easy to shake, and the gap between the two ends after forming is large, which is inconvenient for welding. Thereby affecting the welding quality and the efficiency of coil forming; and when coiling, it is difficult to realize that the joints at both ends of the forming cylinder are just facing upwards. , at this time, the automatic welding operation cannot be realized, because welding is a precise operation process, once the welding position is wrong, it will directly cause the failure of welding;
