A double sheet metal synchronous bending mechanism with correcting function

Abstract

The invention provides a double-sheet-metal synchronous bending mechanism with a correcting function, and belongs to the technical field of machining. The double-sheet-metal synchronous bending mechanism comprises a first cam, a second cam and a third end face cam. The first cam, the second cam and the third end face cam are coaxially mounted on a cam shaft. The middle end of a first swing arm ishinged to a first swing arm support seat. A first bending lower bearing block and a second bending lower bearing block are mounted on a bending lower bearing seat. The middle end of a second swing armis hinged to a second swing arm support seat. A first upper pressing block and a second upper pressing block are both mounted on a bending upper bearing block. A first bending block and a second bending block are also mounted on the bending upper bearing block. A sixth cam bearing follower is attached to the third end face cam. A first bending correcting block and a second bending correcting block are mounted on a correcting block bearing seat. According to the double-sheet-metal synchronous bending mechanism, bending machining can be achieved, the correcting function is achieved, the formingquality of two sheet metal parts is effectively improved, the structure is reasonable and compact, and reliability is good.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a double-sheet metal synchronous bending mechanism with a correction function. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. Cutting processing refers to the processing method of using cutting tools (including cutting tools, grinding tools and abrasives) to cut off the excess material layer on the blank or workpiece into chips, so that the workpiece can obtain the specified geometric shape, size and surface quality. The technological characteristics of cutting processing are determined by the structure of the cutting tool and the relative motion between the cutting tool and the workpiece. According to process characteristics, cutting processing can gener...

Problems solved by technology

However, the current bending machine can generally only process one kind of workpiece at a time, but many sheet metal parts are used in pairs, and processing twice will cause a large difference in the processing of the two sheet metal parts used together, especially In precision equipment, it seriously affects the use of

Moreover, the current common sheet metal forming equipment has no correction function, which is not conducive to the precision processing of sheet metal parts
