Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a clamping and turning device for sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates. The products processed by sheet metal processing are called sheet metal parts. The positioning and clamping mechanism of existing sheet metal parts has a simple structure and often only plays the role of positioning and clamping. When the sheet metal parts need to be flipped, it is necessary to manually disassemble the sheet metal parts, flip them manually and then install them. This operation method is time-consuming and labor-intensive, with high labor intensity and low production efficiency.

[0003] The publication (announcement) number is CN212193051U, which discloses a positioning and clamping mechanism for sheet metal parts, specifically relates to the technical field of sheet metal parts processing equipment, including a bottom plate, a slide groove is provided on the top of the bottom plate, and clamping and flipping mechanisms are provided on both sides above the bottom plate. The clamping and flipping mechanisms include a vertical plate, the bottom end of the vertical plate is slidably connected to the inner side of the slide groove, the inner side wall of the vertical plate is provided with an annular groove, and the inner side of the vertical plate is provided with a movable circular plate. The utility model is provided with a bottom plate, a slide groove, a clamping and flipping mechanism, a first concave plate, a second concave plate, a first drive motor, a screw rod, and a second drive motor, so that the sheet metal parts can be clamped and flipped conveniently, and the sheet metal parts can be clamped by the first cylinder driving the clamping plate, which is convenient to operate. The sheet metal parts can be automatically flipped by the first drive motor driving the movable circular plate to rotate, avoiding the trouble of manual disassembly and installation, thereby saving time, improving work efficiency, and reducing the labor intensity of the staff.

[0004] Although the above scheme realizes the positioning, clamping and automatic flipping of sheet metal parts, the overall height consistency of the annular plate that provides auxiliary support for the bottom of the sheet metal parts is difficult to adapt to the specific shape of the sheet metal parts. In addition, the height position adjustment of the annular plate requires the cooperation of a cylinder, and the operating cost of the equipment for lifting and mobilizing the auxiliary support component is high. For this reason, we propose a clamping and flipping device for sheet metal processing. Utility Model Content
