Description

Technical Field

[0001] This utility model relates to the technical field of corrugated guardrail processing, and in particular to a punching device for the surface of corrugated guardrails. Background Technology

[0002] Corrugated beam guardrails are a major form of semi-rigid guardrails. They are continuous structures made of corrugated steel guardrail panels spliced ​​together and supported by posts. They utilize the deformation of the soil base, posts, and beams to absorb collision energy and force out-of-control vehicles to change direction and return to their normal driving direction, preventing vehicles from running off the road and protecting vehicles and passengers, thus reducing losses from accidents. During the workshop production process, corrugated beam guardrails typically have through holes machined at both ends for connection and fixation with the posts. Therefore, drilling is required to accommodate the actual installation needs of the guardrails. The prior art announcement CN219052614U discloses a field installation punching device for guardrail panels, including a trolley frame, a gantry frame, a limiting sliding mechanism, and a positioning mechanism. A fixed support plate spans across the trolley frame, and a gantry frame is fixed above the support plate. A hydraulic punching machine is fixedly installed in the middle of the gantry frame, with the punch of the hydraulic punching machine punching vertically downwards. A cavity that mates with the punch is fixed in the middle of the support plate, and the cavity is aligned with the center of the punch. The wave groove of the guardrail panel to be punched is engaged in the cavity. The limiting sliding mechanism is used to assist the horizontal sliding feed of the guardrail panel. The positioning mechanism is used for the horizontal feed positioning of the guardrail panel, but it can only process one hole at a time. The lack of support for the guardrail panel during punching makes it easy for the guardrail panel to deform, affecting subsequent installation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a punching device for the surface of a corrugated guardrail that can press the punched part according to the shape of the corrugated guardrail, process multiple through holes at one time, and improve processing efficiency.

[0004] This utility model discloses a punching device for the surface of a corrugated guardrail, comprising a worktable, a base box, a holding assembly, a punching component, and a supporting component. The worktable is installed on the top of the base box, and the holding assembly is installed on the top of the worktable. The punching component is installed inside the holding assembly, and the supporting components are installed at both ends of the worktable. When the corrugated guardrail is placed on the top of the worktable, the supporting components can lift the bottom of the corrugated guardrail to prevent it from shaking and affecting the processing quality. The holding assembly can press the punching part according to the shape of the corrugated guardrail, and the punching component performs the punching operation on the corrugated guardrail, processing multiple through holes at one time, which helps to improve processing efficiency and processing quality.

[0005] Preferably, the pressing assembly includes a support base, multiple columns, a top plate, two telescopic cylinders, and an upper pressing seat. The support base is installed on the top of the workbench, and the multiple columns are respectively installed at the four corners of the top of the workbench.

The upper pressing seat is installed at the telescopic end of the bottom of the telescopic cylinders. The opposite side of the support base and the upper pressing seat is set to a shape that matches the corrugated guardrail panel. After the corrugated guardrail panel is placed on the workbench, it is moved to the top of the support base, and the telescopic cylinders are activated to push the upper pressing seat downward. This can press the punching part according to the shape of the corrugated guardrail panel, ensuring the stability during punching and improving the punching quality.

The telescopic end of the second cylinder extends into the second processing chamber and a second push block is installed. A punching hole is opened at the bottom of the upper pressure seat corresponding to the positions of the first punch head and the second punch head. After the corrugated guardrail is fixed, the first cylinder is started to push the trapezoidal push block to move upward. The trapezoidal push block pushes the push block to make the first punch head cooperate with the punching hole to punch holes at both ends of the corrugated guardrail. The second cylinder is started to push the second push block to move upward and contact the push plate to push the second punch head to move upward, punching holes in the middle position of the corrugated guardrail.
