Description

Technical Field

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

[0002] Highway guardrail panels consist of two corrugated steel guardrail panels and two posts fixedly clamped between them. During normal highway operation, the guardrail uses plug-in posts that can be easily inserted into pre-set insertion holes at the opening, providing isolation and protection. It also complements the guardrail strip along the outer edge of the highway, creating a neat, uniform, and aesthetically pleasing appearance. Because highway guardrail panels are initially quite long, they are then cut to the required dimensions.

[0003] The existing guardrail cutting devices are inconvenient to use because corrugated guardrails are divided into double-wave and triple-wave guardrails, which affects the accuracy of guardrail cutting. Therefore, a cutting 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 cutting device for processing highway guardrail panels, 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 cutting device for processing highway guardrail panels, including a processing table, a limit mechanism provided on the processing table, a device frame fixedly connected to the processing table, a motor fixedly connected to the device frame, a threaded rod fixedly connected to the output end of the motor, an adjusting seat threadedly connected to the threaded rod, a second hydraulic cylinder fixedly connected to the bottom of the adjusting seat, a cutting motor fixedly connected to the telescopic end of the second hydraulic cylinder, and a cutting blade fixedly connected to the output end of the cutting motor;

[0006] The limiting mechanism includes a fixed frame and a bidirectional screw. The bidirectional screw is rotatably connected to the inside of the fixed frame via a bearing. A fixed plate is threaded onto the bidirectional screw. A wheel frame is fixedly connected to the bottom of the fixed plate. A guide wheel is rotatably connected to the wheel frame via a bearing. A first hydraulic cylinder is fixedly connected to the fixed frame. A roller frame is fixedly connected to the telescopic end of the first hydraulic cylinder. A pressure roller is rotatably connected to the roller frame via a bearing.

[0007] Preferably, the fixing frame is fixedly connected to the processing table, the bidirectional screw is fixedly connected to a throttle, and the roller frame is fixedly connected to a limit rod, which can limit the roller frame.

[0008] Preferably, the processing table has a guide opening, and a limit block is slidably connected inside the guide opening. The limit block is fixedly connected to the bottom of the wheel frame. The limit block and the guide opening can limit the wheel frame.

[0009] Preferably, the adjusting seat is slidably connected inside the device frame, and the adjusting seat has an internal threaded hole. The threaded rod is threadedly connected inside the internal threaded hole, and the adjusting seat can be moved by rotating the threaded rod.

[0010] Preferably, the processing table is provided with a collection mechanism, which includes a support plate and a discharge port. The support plate is fixedly connected to the support legs of the processing table, and the discharge port is opened on the processing table. The collection mechanism can collect the metal chips that fall during cutting.

[0011] Preferably, a collection box is placed on the support plate, and a handle is fixedly connected to the collection box. The support plate can support the collection box.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This cutting device for highway guardrail processing works by placing the guardrail on the processing table. The operator turns the throttle to drive the double-ended screw to rotate, bringing the two wheel frames closer together. This allows the guide wheels on both sides to limit the guardrail on both sides. Then, the first hydraulic cylinder is activated to lower the roller frame, causing the pressure roller to press down on the surface of the guardrail, thus limiting the guardrail. This facilitates quick adjustment for guardrails of different sizes, preventing the guardrail from shifting during the pushing process and warping during cutting, thereby improving the accuracy of guardrail cutting.

[0014] 2. This cutting device for highway guardrail processing can collect metal shavings falling from the material outlet by setting a collection box below the cutting blade, which facilitates the centralized processing of metal waste by workers in the later stage, and further improves the practicality of the cutting device.

[0025] Please see Figure 1-5One embodiment of this utility model is: a cutting device for processing highway guardrail panels, including a processing table 1, a limiting mechanism 2 provided on the processing table 1, a device frame 4 fixedly connected to the processing table 1, a motor 5 fixedly connected to the device frame 4, a threaded rod 6 fixedly connected to the output end of the motor 5, an adjusting seat 7 threadedly connected to the threaded rod 6, a second hydraulic cylinder 8 fixedly connected to the bottom of the adjusting seat 7, a cutting motor 9 fixedly connected to the telescopic end of the second hydraulic cylinder 8, and a cutting blade 10 fixedly connected to the output end of the cutting motor 9;

[0026] The limiting mechanism 2 includes a fixed frame 201 and a bidirectional screw 202. The bidirectional screw 202 is rotatably connected to the inside of the fixed frame 201 via bearings. A fixed plate 203 is threaded onto the bidirectional screw 202. A wheel frame 204 is fixedly connected to the bottom of the fixed plate 203. A guide wheel 205 is rotatably connected to the wheel frame 204 via bearings. A first hydraulic cylinder 208 is fixedly connected to the fixed frame 201. A roller frame 209 is fixedly connected to the telescopic end of the first hydraulic cylinder 208. A pressure roller 210 is rotatably connected to the roller frame 209 via bearings. By moving the guardrail plate... After being placed on the processing table 1, the operator turns the handle 207 to drive the bidirectional screw 202 to rotate, causing the two wheel frames 204 to move closer together. This allows the guide wheels 205 on both sides to limit the two sides of the guardrail. Then, the first hydraulic cylinder 208 is activated to lower the roller frame 209, causing the pressure roller 210 to press down onto the surface of the guardrail, thus limiting the guardrail. This facilitates quick adjustment according to different sizes of guardrails, preventing the guardrail from shifting during the pushing process and warping during cutting, thereby improving the accuracy of the guardrail during cutting.

[0027] The fixed frame 201 is fixedly connected to the processing table 1. The handle 207 is fixedly connected to the bidirectional screw 202. The limit rod 211 is fixedly connected to the roller frame 209. The limit rod 211 can limit the roller frame 209.

[0029] The adjusting seat 7 is slidably connected inside the device frame 4. The adjusting seat 7 has an internal threaded hole, and the threaded rod 6 is threadedly connected inside the internal threaded hole. The adjusting seat 7 can be moved by rotating the threaded rod 6.

[0030] Working principle: After the guardrail panel is placed on the processing table 1, the operator turns the handle 207 to drive the bidirectional screw 202 to rotate, so that the two wheel frames 204 move closer to each other, and the guide wheels 205 on both sides limit the two sides of the guardrail panel. Then, the first hydraulic cylinder 208 is activated to lower the roller frame 209, so that the pressure roller 210 presses down on the surface of the guardrail panel, which plays a limiting role in the guardrail panel. This allows for quick adjustment according to different sizes of guardrail panels, avoids the guardrail panel from shifting during the pushing process and warping during cutting, and improves the accuracy of the guardrail panel during cutting.

The collection mechanism 3 includes a support plate 301 and a discharge port 304. The support plate 301 is fixedly connected to the support leg of the processing table 1, and the discharge port 304 is opened on the processing table 1. The metal chips falling from the cutting table can be collected by the collection mechanism 3.
