Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a multi-angle bending and forming device for stainless steel sheets. Background Technology

[0002] Stainless steel sheets have a smooth surface and high plasticity, toughness, and mechanical strength. They are resistant to corrosion from acidic and alkaline gases, solutions, and other media. To meet the requirements of use, stainless steel sheets need to be bent using multi-angle bending devices.

[0003] However, in the bending process of stainless steel plates, due to process requirements, sometimes the steel plate is not bent as a whole, but only a part of the steel plate is bent, and there are requirements for the bending angle and width. The current solution can only bend the steel plate as a whole and cannot bend the steel plate locally, so it cannot be used for such process requirements. Therefore, in order to solve the above problems, a multi-angle bending device for stainless steel plate processing is proposed.

[0004] For example, Chinese patent CN222036399U discloses a multi-angle bending device for processing stainless steel plates, including a base with a feeding port on the base and a hydraulic cylinder installed on the upper end of the base. A bending component is provided on one side of the output end of the hydraulic cylinder. A positioning block is fixedly connected to the upper end of the base, and an electromagnet is installed on the end of the positioning block near the feeding port. A spring is fixedly connected to the inner wall of the positioning block. This solution makes the bending head for bending the steel plate detachable, and the user can replace the corresponding bending head according to the bending angle requirements of the steel plate to achieve bending of the steel plate at different angles. This solution is provided with a pair of support blocks with adjustable spacing. By adjusting the spacing of the support blocks, the width of the bending part of the steel plate can be controlled, thereby meeting specific process requirements. Thus, this device can realize the control of the bending position, bending angle and bending width of the steel plate, improving the practicality and functionality of the device.

[0005] However, the equipment requires frequent mold changes, making operation cumbersome and resulting in low production efficiency. Utility Model Content
