Metal plate hemming mechanism

Abstract

The invention provides a metal plate hemming mechanism which comprises a bottom plate. A supporting piece and a U-shaped frame with a downward opening are fixed at the upper end of a side plate, a movable rod which is vertically arranged penetrates through the upper end of the U-shaped frame, the lower end of the movable rod is provided with a pressing plate through a first spring, guide columns are fixed at the front end and the rear end of the movable rod, driving blocks are arranged at the front end and the rear end of the movable rod, an inclined groove with the higher left portion and thelower right portion and a horizontally-arranged horizontal groove are formed in each driving block, each inclined groove communicates with the corresponding horizontal groove, the two guide columns are inserted into the inclined grooves in the two driving blocks, spur racks are fixed to the right portions of the lower ends of the horizontal grooves, the front wall and the rear wall inside the U-shaped frame are rotationally provided with local annular racks, a bent plate is arranged between the two local annular racks, the bent plate is installed on the left side of the supporting piece, theleft ends of the two driving blocks are jointly fixed to a connecting plate, and a driving piece is installed at the left end of the connecting plate. The metal plate hemming mechanism is reasonable in structure, convenient and fast to operate and good in using effect.

Description

technical field [0001] The invention relates to a metal plate curling mechanism, which belongs to the technical field of metal plate processing. Background technique [0002] When making the metal tank body, a method of fastening the two edges to each other and connecting them at the same time when the cylinder body is formed can save the welding process and make the forming cylinder body fast and simple. This method needs to curl the metal sheet before the cylinder is formed. At present, the sheet metal curling mechanism is often used for the curling work. [0003] Chinese Patent Publication No. CN102814375B discloses a fixing part for pressing the metal sheet and a hemming part for curling in the metal sheet curling mechanism. Compression, and then drive the crimping parts to carry out crimping work through the swing mechanism, the operation needs to be divided into two steps, and the driving parts also need to be set into two, which is not easy to use. Contents of the ...
