Description

Technical Field

[0001] The utility model relates to the field of guardrail plate processing, and more specifically, to a novel bending device for producing three-wave guardrail plates. Background Art

[0002] Guardrails use the deformation of soil foundations, columns, beams, and polycarbonate panels to absorb collision energy and force out-of-control vehicles to change direction and return to their normal driving direction, preventing them from running off the road, thereby protecting vehicles and passengers and reducing losses caused by accidents.

[0003] For example, a metal guardrail corner bending device disclosed in announcement No. CN219881005U includes a base plate, the top of the base plate is fixedly connected to a frame sleeve, one side of the frame sleeve is fixedly connected to an internal threaded sleeve, and a fixing component is sleeved inside the internal threaded sleeve. The fixing component includes a fixing screw, one end of the fixing screw is rotatably connected to a side plate, and the top of the base plate away from the frame sleeve is fixedly connected to a pushing component, the guardrail is inserted into the frame sleeve and fixed, the first electric hydraulic cylinder works to push the L-shaped pushing plate into the frame sleeve, pushes the bottom end of the guardrail to make it bend, and bends the end of the guardrail. As the L-shaped pushing plate moves, the end of the guardrail can be bent into a right angle, and the second electric hydraulic cylinder works to push the pushing block upward, so that the end of the guardrail bent at a right angle can be bent again, and the end of the guardrail can be bent into a U shape. The electric hydraulic cylinder is used to push the bottom end of the guardrail to bend, so that a relatively hard metal guardrail can be bent.

[0004] It can be seen from the above-mentioned public scheme that the current limiting device of the guardrail plate is not easy to limit the front and rear blocking of guardrail plates of different sizes, and the guardrail plate is prone to splashing when bending, which not only affects the processing work, but also the guardrail plate is easy to splash and accidentally injure the staff. At the same time, some stamping devices are not easy to perform three waves of bending deformation at one time, which reduces work efficiency and workload. Utility Model Content

The stopper is connected by the second telescopic rod, so that the position of the stopper can be conveniently moved and adjusted, and the guardrail plates can be conveniently blocked and limited to prevent the guardrail plates from moving left and right and affecting the bending work of the guardrail plates. When bending, the pressure plate presses the guardrail plates downward to limit the position to prevent the guardrail plates from splashing when bending. At the same time, through the setting of the cylinder, it is convenient to drive the pressure plate to move up and down and lift through the automatic movement of the cylinder rod, so that the pressure plate can be automatically pressed down on the upper end of the guardrail plate, so that it can slide and engage with the lower end of the pressure plate through multiple hidden grooves, so that the guardrail plate can complete three-wave bending deformation at one time.
