Description

Technical Field

[0001] This utility model relates to the field of highway guardrail processing technology, specifically a punching device for highway guardrail processing. Background Technology

[0002] Highway guardrails, as crucial facilities for modern road traffic safety, are widely used on highways, urban roads, bridges, and other locations. Their primary function is to prevent vehicles from running off the road in case of loss of control, protecting the safety of vehicles and passengers, while also serving as barriers and warnings. With the rapid development of highway construction, the demand for highway guardrails is constantly increasing, placing higher requirements on their processing quality and production efficiency. Punching is one of the key processes in highway guardrail manufacturing, mainly used to process holes in the guardrail panels for installing posts or other connecting components. Traditional highway guardrail punching devices mainly consist of punching dies, drive mechanisms, and worktables, enabling basic punching functions.

[0003] Traditional punching devices may produce waste materials (such as metal shavings after punching) that can fly up during the punching process, causing injury to the operator's eyes and body, and creating a safety hazard in the operating environment. Therefore, a punching device for highway guardrail processing is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a punching device for processing highway guardrails, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a punching device for processing highway guardrails, including a workbench, on which a punching mechanism and a protective mechanism are respectively arranged;

[0006] The punching mechanism includes: a mounting frame connected to the top of the workbench, the mounting frame being in an inverted "L" shape, an electric hydraulic cylinder connected to the inner top of the mounting frame, the electric hydraulic cylinder being self-locking, a support plate connected to the piston end of the electric hydraulic cylinder, a slider slidably connected to the bottom of the support plate, a mounting plate connected to the bottom of the slider, and a plurality of punching heads connected at equal intervals to the bottom of the mounting plate;

[0007] The protective mechanism includes: a slide bar slidably connected to the top of the workbench; a transparent protective plate connected to the top of the slide bar; a connecting plate connected to the top of the slide bar; a hinge arm hinged to the top of the connecting plate; and the other end of the hinge arm hinged to the right side of a support plate. By activating an electric hydraulic cylinder, the support plate and the punch head are driven to press vertically downwards to complete the punching. Simultaneously, the support plate moves the connecting plate via the hinge arm, and the connecting plate drives the slide bar and the transparent protective plate to slide synchronously along the workbench groove, forming a protective barrier to prevent metal chips from flying during punching and ensuring the safety of the operator.

[0008] Preferably, the top of the workbench is provided with a sliding groove, and the slide bar is slidably connected in the sliding groove. The sliding groove provides precise guidance for the slide bar, ensuring that the transparent protective plate moves smoothly without shaking when it moves with the support plate, effectively blocking splashes.

[0009] Preferably, there are two of each of the sliding strip, transparent protective plate, and hinge arm, which are arranged opposite each other on the front and rear sides of the support plate to form a front and rear enclosed protective structure that covers the entire circumference of the punched area, further improving safety compared to single-sided protection.

[0010] Preferably, a fixed plate is connected to the bottom of the support plate, and a lead screw is rotatably connected to the front of the fixed plate via a bearing. The slider is threadedly connected to the outer wall of the lead screw. A motor is connected to the bottom of the support plate via a bracket, and the front end of the lead screw is connected to the output end of the motor. By starting the motor, the lead screw is driven to rotate, which in turn drives the slider to move back and forth along the limiting groove, thereby adjusting the front and rear positions of the mounting plate and the punching head to adapt to the processing requirements of different hole positions of the guardrail and significantly improve the punching efficiency.

[0011] Preferably, a limiting groove is provided at the bottom of the support plate, and the top of the slider is slidably connected in the limiting groove. The limiting groove limits the slider, so that the rotational motion of the slider is converted into forward and backward movement.

[0012] Preferably, the top of the worktable has two cylinders connected to each other, and the piston ends of the two cylinders are respectively connected to clamping plates. By activating the cylinders, the clamping plates are driven to clamp the guardrail, providing a stable clamping force, preventing the workpiece from shaking during punching and affecting the processing quality, and improving processing stability and safety.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. The punching device for highway guardrail processing drives the support plate and punching head to press down vertically by starting the electric hydraulic cylinder to complete the punching. At the same time, the support plate drives the connecting plate to move through the hinge arm. The connecting plate drives the slide bar and transparent protective plate to slide synchronously along the slide groove of the worktable to form a protective barrier to prevent metal chips from flying during punching and to ensure the safety of the operator.

[0015] 2. This punching device for highway guardrail processing drives the lead screw to rotate by starting the motor, which in turn moves the slider back and forth along the limiting groove, thereby adjusting the front and rear positions of the mounting plate and the punching head to adapt to the processing requirements of different hole positions on the guardrail plate, significantly improving punching efficiency. By starting the cylinder, the clamping plate is driven to clamp the guardrail plate, providing stable clamping force to prevent the workpiece from shaking during punching and affecting the processing quality, thus improving processing stability and safety.
