Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail production technology, specifically a forming machine for guardrail production. Background Technology
[0002] The semi-rigid guardrail is a major form of guardrail, a continuous structure made of corrugated steel guardrail panels spliced together and supported by main posts. It absorbs energy during vehicle collisions, making it 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] During the production of guardrails, the sides of the guardrails need to be ground to prevent scratches. However, most existing guardrail forming machines do not have a grinding function and instead perform grinding after processing, or they can only grind the edges of guardrails of the same width, which is inefficient.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1
[0024] like Figure 1-3 As shown, this utility model provides a forming machine for guardrail production, including a worktable 1, a support frame 2 fixedly connected to the lower end of the worktable 1, a cold pressing forming mechanism 3 provided at the upper end of the worktable 1, an edge grinding device 4 and a cutting device 5 provided at the upper end of the worktable 1; the edge grinding device 4 includes a mounting groove 401, which is formed on the surface of the worktable 1, a motor 402 fixedly connected to the outer wall of the worktable 1, a bidirectional lead screw 403 fixedly connected to the output end of the motor 402, the other end of the bidirectional lead screw 403 being rotatably connected to the inner wall of the mounting groove 401 through a bearing, a moving block 404 being threadedly connected to the outer wall of the bidirectional lead screw 403, a fixed shaft 405 fixedly connected to the top of the moving block 404, and an edge grinding disc 406 rotatably connected to the outside of the fixed shaft 405.
[0025] The side wall of the movable block 404 fits tightly against the inner wall of the mounting groove 401, thereby preventing the movable block 404 from rotating with the bidirectional lead screw 403.
[0026] In this embodiment, by setting the edge grinding device 4, the distance between the two edge grinding discs 406 can be adjusted, thereby meeting the edge grinding needs of guardrails of different widths.
[0027] In use, when it is necessary to adjust the distance of the grinding disc 406 according to the width of the guardrail, the motor 402 is started, which drives the bidirectional lead screw 403 to rotate, thereby causing the moving block 404 to move simultaneously to the center and both sides inside the mounting groove 401. This, in turn, drives the grinding disc 406 to move simultaneously to the center and both sides through the fixed shaft 405, thereby adjusting the distance between the two grinding discs 406 to meet the grinding needs of guardrails of different widths.
[0028] Example 2
[0029] like Figure 1As shown, based on embodiment 1, a cutting device 5 is added, including a fixed frame 501. The fixed frame 501 is fixedly connected to the upper end of the workbench 1. A hydraulic cylinder 502 is fixedly connected to the upper end of the fixed frame 501. A mounting plate 503 is fixedly connected to the output end of the hydraulic cylinder 502. A cutting blade 504 is fixedly connected to the bottom of the mounting plate 503.
[0030] A controller 505 is provided on the side of the fixing frame 501. By setting the controller 505, the cutting speed and frequency of the cutting device 5 can be controlled to control the cutting length of the guardrail.
[0031] The inner side of the fixing frame 501 is provided with a sliding groove 506, and the two ends of the mounting plate 503 are slidably connected inside the sliding groove 506, thereby ensuring the stability of the mounting plate 503 when it moves up and down.
[0032] The surface of the worktable 1 is provided with a cutting groove 507, which can ensure the cutting range of the cutting blade 504 and avoid damage to the worktable 1.
[0033] In this embodiment, by setting the cutting device 5, the cold-pressed guardrail panel can be cut instantly, which improves the processing efficiency. At the same time, the cutting speed can be controlled by the controller 505, thereby ensuring the cutting length of the guardrail panel.
[0034] When in use, the hydraulic cylinder 502 is activated to move the mounting plate 503 downward. During the movement, both ends of the mounting plate 503 will slide inside the slide groove 506, thereby ensuring its stability during movement. The cutting blade 504 at the bottom of the mounting plate 503 will also move downward with the mounting plate 503, thereby cutting the guardrail plate that has been cold-pressed and formed on the upper end of the workbench 1.
