Description

A positioning and cutting device for processing stainless steel doors and windows

Technical Field

The invention relates to the technical field of door and window processing, and in particular to a positioning and cutting device for processing stainless steel doors and windows.

Background Art

With the continuous development of society, the types of doors and windows have also undergone various changes. Nowadays, most common doors and windows are aluminum alloy or stainless steel doors and windows. This type of door and window is formed by cutting, grinding, spraying and assembling stainless steel to form the final door and window products. Cutting is the most critical step. Low cutting accuracy will directly lead to larger gaps in doors and windows, which cannot meet the needs. The existing cutting technologies include manual cutting and mechanical automatic cutting. Manual cutting is difficult to ensure cutting accuracy, while the existing mechanical cutting uses two cutting blades with different angles to cut a trapezoidal steel, and the distance control between the two blades is not accurate enough, which will also cause waste of raw materials, or one blade is used for cutting, but the steel needs to be flipped, which is more cumbersome.

The present invention is designed to address the defects of the prior art. When in use, the present invention can continuously cut stainless steel materials, and can perform continuous cutting by alternating angles without flipping the stainless steel materials, so that the shape of the stainless steel materials after cutting is a trapezoid that meets the requirements of window installation; the present invention is provided with a hollow area in the middle of the conveying platform, and a long slidable rod is provided in the hollow area, so that the cutting blade can be adjusted at a certain distance in space, so that the length of the stainless steel material cut is different; the positioning plate of the present invention can automatically fit the end face of the cut stainless steel material, so as to limit one end of the stainless steel material, and high-precision materials can be cut by only controlling the cutting position of the other end.

Then, the stainless steel material 17 is manually pushed to continue to move, and the just-cut bevel is clamped by the positioning plate 29, and then the limit rod 34 clamps the stainless steel material 17 again, and then the cutting blade 2 rotates again to cut, and so on and so forth, the trapezoidal stainless steel material 17 can be continuously cut.
