Portable and adjustable straight flange turning-up machine and operation method thereof

Abstract

The invention provides a portable adjustable straight-edge flanging device, which includes a fixed block, a fixed plate, an adjustment block, a positioning rod, a pressure wheel and an auxiliary wheel, and is characterized in that: the fixed block and the fixed block are arranged with The connecting plate, the fixed plate is provided with a positioning plate, the adjustment block is arranged on the fixed plate, one end of the positioning rod is arranged on the fixed block through a fastening bolt, and the other end passes through the adjustment block and the fixed plate Afterwards, a flanging bearing is arranged, and the pressure roller is arranged on a fixed plate through a fixed rod. In the present invention, a flanging bearing is arranged on the positioning rod, a pressing wheel is arranged on the fixing plate, and the adjusting block is set as a structure capable of adjusting the position on the positioning rod, so that the distance between the pressing wheel and the flanging bearing can be adjusted , improve the quality of flanging of the outer metal skin of the bus, expand the scope of application of the straight edge flanging device, and can also perform flanging of the outer metal skin of the bus at 0‑90° and different heights, reducing the need for manufacturing multiple straight edges The cost of the flanger.

Description

technical field [0001] The invention relates to a flanging device, in particular to a portable adjustable straight edge flanging device and an operation method thereof. Background technique [0002] In the production of passenger cars, the outer skin that wraps the body frame needs to be hemmed. At present, the working length of the plate bending machine is generally 4 to 6 meters. Block docking or bending on a 6-meter bending machine in multiple knives. The multi-block docking method has many joints, difficult surface treatment in the later stage, high cost, time-consuming, and manpower; the multi-knife bending method is in production. In the process of multi-knife bending, the consistency is poor, large workpieces require multiple people to operate, and safety accidents are prone to occur. In addition, if special equipment is purchased for flanging, the initial investment in equipment is large, the product output is single, the quantity is small, the cost is high, and the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems of low work efficiency, low quality of flanging, high labor intensity of operators and low safety performance existing in the flanging process of the existing outer metal skin of passenger cars, and to provide a Portable and adjustable straight edge flanging device with convenience, wide application range, good flanging quality, low labor intensity of operators, high safety performance, small size and low operating cost
