A snapping and aligning device for large-format steel plates

Abstract

A device used for neatly beating and aligning a large-width steel plate comprises at least three positioning devices. At least one positioning device is arranged on the lateral side in the width direction of the steel plate. At least two positioning devices are arranged on the lateral side in the length direction of the steel plate. Each positioning device comprises a positioning base, a positioning installation frame and at least three neatly beating devices, wherein a slide groove is formed in a side face of the base, one end of the positioning installation frame is positioned in the slide groove of the positioning base and is movably connected to the positioning base through an adjustment bolt, a positioning block is arranged at the other end of the positioning installation frame, at least one neatly beating device is arranged on the lateral side in the width direction of the steel plate, and at least two neatly beating devices are arranged on the lateral side in the length direction of the steel plate. Each neatly beating device comprises an installation machine frame, a piston cylinder, a dual-action cylinder and a neatly beating plate, wherein cylinder bodies are arranged on the installation machine frame through fixing shafts and cylinder installation blocks, the upper portion of the neatly beating plate is movably connected to a piston rod of the piston cylinder through a pin shaft, the middle of the neatly beating plate is connected to one end of the installation machine frame through a pivoting shaft, an angle lager than 90 degrees is formed by the upper portion and the lower portion of the neatly beating plate, and the neatly beating plate is driven by the piston cylinder through the piston rod to rotate around the fixing shaft in a reciprocating mode.

Description

technical field [0001] The invention relates to steel plate processing equipment, in particular to a snapping and aligning device for large-format steel plates, and is especially suitable for occasions such as laser or plasma cutting that require high cutting precision of steel plates. Background technique [0002] In the cutting process of the steel plate, since the initial position of the steel plate has a great influence on the size and shape error of the steel plate, the initial positioning of the steel plate is required. The deformation of the thin steel plate is large, and the ordinary positioning block cannot meet the high requirements of reducing the small deformation of the steel plate by laser or plasma cutting. The commonly used steel plate positioning has no adjustment function. For the positioning device installed on the non-fixed frame, it is necessary to compensate the parallelism error between the cutting machine and the base from the cutting system control l...

Problems solved by technology

The deformation of the thin steel plate is large, and the ordinary positioning block cannot meet the high requirements of reducing the small deformation of the steel plate by laser or plasma cutting

The commonly used steel plate positioning has no adjustment function. For the positioning device installed on the non-fixed frame, it is necessary to compensate the parallelism error between the cutting machine and the base from the control level of the cutting system. If the non-fixed frame is replaced, the error value will be reduced. It needs to be reset from the system level, which affects the stability of the system, and has higher requirements for mechanical performance

[0003] Chinese Patent No. CN102601641A discloses a steel plate positioning mechanism. The technical solution is to adjust the positioning position of the steel plate by using sleeves with different diameters in the outer ring of the positioning block. This method has technical difficulties for cutting operations that require precise adjustment of positioning. Guarantee the positioning accuracy requirements for large-format steel plates, and have a great impact on the shape error of cut steel plates that need to be kept

[0005] Chinese patent CN201713138U discloses a sheet material alignment device. This technical solution uses sheet material limit, and the sheet material alignment position is determined by the installation position of the sheet material alignment device. It cannot adapt to the situation of sheet material changes, and the positioning accuracy satisfies Without the requirement of high-precision cutting, the steel plate is easily scratched
