Bending machine and bending method of baking cup mat steel sheet

Abstract

The invention relates to the technical field of steel machining, in particular to a bending machine. The bending machine comprises a machine box, a base, a driving device I arranged in the machine box, a driving roller connected to an output end of the driving device I, and a driving device II and a driven roller device arranged in the base; the driven roller device comprises an adjusting mechanism and two driven rollers parallel to the driving roller, and the driven rollers are rotatably connected with the adjusting mechanism; and the driving device II is used for driving the adjusting mechanism to be close to or away from the driving roller. The adjusting mechanism and the driven rollers are driven by the driving device II to move, the distance between the driven rollers and the driving roller is adjustable, and the bending machine is suitable for various steel sheets with different thicknesses; and the steel sheets are not interfered by special-shaped parts at the two ends of the steel sheets when being placed on the bending machine. The invention further provides a bending method of a baking cup mat steel sheet, the two driven rollers can conveniently machine the parts, close to the two special-shaped parts, of a steel sheet body, and the working efficiency of the bending machine is improved.

Description

technical field [0001] The invention relates to the technical field of steel processing, in particular to a bending machine and a bending method for a steel sheet of a baking coaster. Background technique [0002] Existing bending machines can only perform arc bending or rounding processing of steel with a specific shape, and the relative positions of the driving roller and driven roller of the existing bending machine cannot be adjusted, so that the steel that the bending machine can process The thickness and shape of the steel are fixed, and the radius of the rolled or arc-bent steel is also fixed. However, in actual production and processing, it is often necessary to process steels of various shapes or thicknesses, and the existing bending machines are only suitable for processing the same steel with constant thickness or shape, and cannot be applied to many different shapes. The shape or thickness of steel is required for arc bending or rounding, which leads to low effi...

Problems solved by technology

However, in actual production and processing, it is often necessary to process steels of various shapes or thicknesses, and the existing bending machines are only suitable for processing the same steel with constant thickness or shape, and cannot be applied to many different shapes. The shape or thickness of steel needs to be processed in arc bending or rounding, which leads to low efficiency and high cost of arc bending or rounding of bending machine

Moreover, when the existing bending machine performs arc bending or rolling on the steel sheet with special-shaped parts at both ends, the special-shaped parts at both ends of the steel sheet cannot pass through the gap between the driven roller and the driving roller, so that the steel sheet The middle part cannot be normally placed in the gap between the driven roller and the driving roller, and the special-shaped parts at both ends of the steel sheet interfere with the entry of the middle part of the steel sheet into the gap between the driving roller and the driven roller
