Description

Technical Field

[0001] This utility model relates to the field of guardrail production technology, specifically to a pressing tool for guardrail production. Background Technology

[0002] Highway 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 absorb energy during vehicle collisions, making them less prone to damage and providing excellent protection for vehicles and occupants. The bending of highway guardrails increases both aesthetics and strength; they are automatically extruded on a production line, resulting in a clean, undamaged surface and excellent corrosion resistance; surface treatment methods are mature; they are corrosion-resistant, anti-aging, sun-resistant, and resistant to high and low temperatures, with a service life of 10-25 years in outdoor environments; the product has a simple, beautiful, and practical structure, is easy to transport and install, has good anti-theft performance, is less restricted by actual terrain, and is particularly adaptable to mountainous, sloping, and winding areas; its moderate cost makes it suitable for large-scale application.

[0003] For example, Chinese Patent Publication No. CN219899800U, entitled "A Pressing Fixture for Guardrail Production," discloses the following technical solution: This utility model relates to a pressing fixture for guardrail production, including a workbench and two support frames located at the bottom of the workbench. Two block strips are fixed on both sides of the top of the workbench, and a pressing protrusion is provided between the two block strips. Limiting holes are opened on the opposite sides of the two block strips. A pressing mold adapted to the pressing protrusion is provided on the top surface of the workbench between the two block strips. A drive structure for driving the pressing protrusion to move up and down is provided on the side of the two block strips away from the pressing mold. This pressing fixture for guardrail production, by turning on the servo motor to drive the threaded shaft to rotate, the threaded shaft drives the lifting block to move up or down simultaneously, thereby driving the pressing protrusion between the two connecting shafts to press against the pressing mold. Then, the moving block drives the cutting blade to cut the formed aluminum plate, completing the cutting and pressing integrated forming operation, improving production efficiency.

[0004] However, in actual use, it is not convenient for feeding. When it is necessary to put the aluminum plate into the mold, the aluminum plate needs to be manually moved to the aluminum plate rack of this utility model. Then, the aluminum plate needs to be manually pushed in once with each processing, which is time-consuming and labor-intensive and does not save labor. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a pressing fixture for guardrail production, including a workbench 1, with four support legs 2 fixedly connected below the workbench 1. A feeding mechanism 3 is provided above the workbench 1, including a sliding plate 301 fixedly connected to the top of the workbench 1. A limiting mechanism 4 is provided above the sliding plate 301, including a back plate 401 fixedly connected to the top of the workbench 1. A rolling assembly 5 is provided above the back plate 401, including a support plate 501. A connecting plate 502 is rotatably connected to the front of the support plate 501, and a power roller 503 is rotatably connected to the front of the connecting plate 502. The outer surface of the power roller 503... The material is rubber. A motor is installed on the back of the power roller 503. The motor drives the power roller 503 to rotate. The rotation of the power roller 503 will cause the raw material plate on the sliding plate 301 to slide to the left. A handle 504 is fixedly connected to the front of the connecting plate 502. The limiting mechanism 4 also includes an adjusting plate 402. The adjusting plate 402 is fixedly connected to the top of the worktable 1. A threaded rod 403 is threaded through the front of the adjusting plate 402. A limiting plate 404 is rotatably connected to the back of the threaded rod 403. The lower part of the limiting plate 404 is movably attached to the upper part of the sliding plate 301. A limiting post 405 is fixedly connected to the front of the limiting plate 404. The limiting post 405 is movably connected to the front of the adjusting plate 402. A processing mechanism 6 is provided on the right side of the worktable 1.

[0027] In this embodiment, the handle 504 is first pulled to lift the connecting plate 502, and the raw material metal sheet to be processed is placed above the sliding plate 301 on the workbench 1. Then, the position of the sheet is adjusted so that it presses against the back plate 401. At this time, the threaded rod 403 on the adjusting plate 402 is rotated to push the limiting plate 404 toward the sheet until the limiting plate 404 and the back plate 401 form a channel for the sheet, so that the sheet can slide stably and neatly on the sliding plate 301. Then, the handle 504 is lowered so that the power roller 503 presses the sheet. The motor on the back of the power roller 503 drives the power roller 503 to rotate. The rotation of the power roller 503 will cause the raw material sheet on the sliding plate 301 to slide to the left, so as to feed the processing mechanism 6.

[0028] Example 2

[0029] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the processing mechanism 6 includes a pressing groove 601, the upper part of which is flush with the height of the sliding plate 301. The pressing groove 601 is fixedly connected to the left side of the worktable 1. A cutting groove 602 is provided above the pressing groove 601, the specifications of which are adapted to the cutting blade 702. A support frame 603 is provided above the pressing groove 601, the inner surface of which is fixedly connected to the front and back of the pressing groove 601. A pressing block 604 is slidably connected to the inner surface of the pressing groove 601, the pressing block 604 is adapted to the pressing groove 601. A first hydraulic push rod 605 is fixedly connected above the pressing block 604, the upper part of which is fixedly connected to the top of the inner surface of the support frame 603. A cutting component is provided above the pressing block 604. 7. The cutting assembly 7 includes a pressure plate 701 with an opening 704 in the middle. Cutters 702 are fixedly connected to the left and right sides of the pressure plate 701. The cutters 702 are movably fitted to the left and right sides of the pressure block 604. A second hydraulic push rod 703 is fixedly connected to the top of the pressure plate 701. The top of the second hydraulic push rod 703 is fixedly connected to the top of the inner surface of the support frame 603. A limiting assembly 8 is provided below the pressure plate 701. The limiting assembly 8 includes a limiting rod 801, which is fixedly connected to the top of the pressure block 604 and movably passes through the pressure plate 701. A limiting piece 802 is fixedly connected to the top of the limiting rod 801 and movably fits to the top of the pressure plate 701. A first hydraulic push rod 605 is disposed in the opening 704 in the pressure plate 701.

[0030] In this embodiment, when the sheet slides to the left above the pressure groove 601, the first hydraulic push rod 605 pushes the pressure block 604, causing the pressure block 604 to press downward. The pressure block 604 will cooperate with the pressure groove 601 to stamp and shape the sheet. After the sheet is pressed into the required shape, the second hydraulic push rod 703 pushes the pressure plate 701 downward. The pressure plate 701 will cause the cutter 702 to press downward until it is inserted into the cutting groove 602 on the pressure groove 601, thereby cutting off the excess part of the stamped and shaped sheet to complete the processing.
