Technical Field

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

[0002] Chamfering refers to the process of cutting the edges of a workpiece into a certain bevel. Chamfering is used to remove burrs produced by machining on parts and to facilitate assembly. Generally, chamfers are made at the ends of parts. When processing guardrails, the guardrail round tubes need to be welded. Due to technical reasons during the pipe production process, many burrs will be generated at both ends of the pipe. In order to ensure the welding strength, it is necessary to chamfer both ends of the round tubes.

[0003] The patent document, published under CN220921135U, is titled "A Chamfering Machine for Guardrail Processing." It clamps the pipe and then adjusts the position of the chamfering stop connected to the output end of the drive motor through a lifting cylinder, so that both ends of pipes of different diameters can be chamfered.

[0004] Using this existing technology, the chamfered guardrail tubes still need to be removed manually, which is laborious and time-consuming, and cannot be carried out continuously, resulting in low chamfering efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chamfering device for guardrail processing, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a chamfering device for guardrail processing, comprising a chamfering mechanism, a conveying mechanism, and a pressing mechanism;

[0007] The chamfering mechanism is used to chamfer both ends of the guardrail tube;

[0008] The clamping mechanism is used to clamp the guardrail tube when the chamfer is applied;

[0009] The conveying mechanism includes a fixed frame with two mounting plates. Both ends of the mounting plates are semi-circular, and both mounting plates are connected to a drive assembly. The drive assembly is connected to a conveyor belt rotatably connected between the two mounting plates. Mounting components are evenly distributed on the conveyor belt, and support blocks are provided at both ends of the mounting components. Rollers that contact the mounting plates are provided on the support blocks.

[0010] Preferably, the chamfering mechanism includes two support frames, each of which is equipped with a cylinder 1. The piston rod of the cylinder 1 is provided with a slide rail, and a cylinder 2 is provided on the slide rail. The piston rod of the cylinder 2 is provided with a slide block that is slidably connected to the slide rail. The slide block is provided with a drive assembly 2, and a chamfering stop is connected to the drive assembly 2.

[0011] Preferably, the support frame has a guide rod that is connected to the slide rail.

[0012] Preferably, the clamping mechanism includes a mounting frame mounted on two support frames, a cylinder three mounted on the mounting frame, a connecting frame mounted on the piston rod of the cylinder three, the connecting frame being slidably connected to the mounting frame, and both ends of the bottom of the connecting frame being provided with pressure blocks with anti-slip pads.

[0013] Preferably, the mounting assembly includes two fixing rods connected by bolts, both fixing rods being connected to the conveyor belt, and each fixing rod being connected to two support blocks.

[0014] Preferably, the mounting plate has a guide groove, and the fixing rod has a round rod that fits and connects with the guide groove.

[0015] This utility model provides a chamfering device for guardrail processing. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] 1. This chamfering device for guardrail processing places the guardrail tube on two support blocks and conveys it via a conveyor belt. The fixed rod drives the support blocks to move, which in turn drives the rollers to roll along the mounting plate. When it reaches the chamfering mechanism, the chamfering stops on both sides contact the two ends of the guardrail tube, and then the pressing mechanism presses down on the guardrail tube. The bottom of the support block is supported by the rollers contacting the mounting plate, which facilitates the pressing mechanism to press the guardrail tube. After chamfering is completed, the guardrail tube continues to be conveyed. When the support block is conveyed in the reverse direction, the guardrail tube on it will automatically fall down. Therefore, it is not necessary to manually remove the chamfered guardrail tube. The conveyor belt conveying method enables continuous production, thereby improving the chamfering efficiency of the guardrail tube during guardrail processing.

[0018] 2. The chamfering device for the guardrail processing, by setting guide grooves and round rods, allows the fixed rods and support blocks to be guided during transportation, improving the stability during transportation. The fixed rods on both sides are connected by bolts, so that the fixed rods on both sides are connected separately, so that the round rods can be installed in the guide grooves.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-4 This utility model provides the following two technical solutions:

[0026] First embodiment: A chamfering device for guardrail processing, comprising a chamfering mechanism, a conveying mechanism and a clamping mechanism;

[0027] The chamfering mechanism is used to chamfer both ends of the round tubes of the guardrail;

[0028] The clamping mechanism is used to clamp the guardrail tubes during chamfering;

[0029] The conveying mechanism includes a fixed frame 1, on which two mounting plates 2 are provided. The front and rear ends of the mounting plates 2 are semi-circular, allowing the subsequent rollers 6 to roll along the mounting plates 2. Both sides of the mounting plates 2 are connected to the drive assembly 3. The drive assembly 3 is connected to the conveyor belt 4 rotatably connected between the two mounting plates 2. The drive assembly 3 is used to drive the conveyor belt 4 to rotate. Mounting components are evenly arranged on the conveyor belt 4, and support blocks 5 are provided at both the left and right ends of the mounting components. Rollers 6 that contact the mounting plates 2 are provided on the support blocks 5.

[0030] Place the guardrail tube on the two side support blocks 5. Move the installation components via the conveyor belt 4 to transport the support blocks 5 and the guardrail tube on them. When the tube reaches the chamfering mechanism, the clamping mechanism presses down on the guardrail tube. The bottom of the support block 5 is supported by the rollers 6 contacting the mounting plate 2, which facilitates the clamping mechanism to press the guardrail tube. After clamping, the chamfering can begin. After the chamfering is completed, continue conveying. When the support blocks 5 are conveyed backward, the chamfered guardrail tube will fall automatically. Place a collection box under the front of the conveyor belt 4 to collect the fallen guardrail tube.

[0031] The chamfering mechanism includes two support frames 7, each equipped with a cylinder 8. The piston rod of cylinder 8 is mounted on a slide rail 9, and a second cylinder 10 is mounted on the slide rail 9. The piston rod of cylinder 10 is mounted on a slide block 11 that is slidably connected to the slide rail 9. A second drive assembly 12 is mounted on the slide block 11, and a chamfering stop 13 is connected to the drive assembly 12. Cylinder 8 is used to drive the slide rail 9 to rise and fall, so that the height of the chamfering stop 13 can be changed according to the diameter of the guardrail tube. Cylinder 10 drives the chamfering stop 13 to change its lateral position, which can be changed according to the length of the guardrail tube. The drive assembly 12 is used to drive the chamfering stop 13 to rotate to complete the chamfering of the end of the guardrail tube.

[0032] To improve the stability of cylinder 8 during operation, a guide rod 14 connected to slide rail 9 is inserted through the support frame 7.

[0033] The clamping mechanism includes a mounting frame 15 mounted on two support frames 7. The guardrail tube is not obstructed by the mounting frame 15 during transport. A cylinder 16 is mounted on the mounting frame 15. A connecting frame 17 is mounted on the piston rod of the cylinder 16. In order to improve the stability of the connecting frame 17 during lifting, the connecting frame 17 is slidably connected to the mounting frame 15. Both ends of the bottom of the connecting frame 17 are provided with pressure blocks 18 with anti-slip pads 19. The cylinder 16 drives the pressure blocks 18 to move down, and the guardrail tube can be clamped by the anti-slip pads 19.

[0034] The mounting assembly includes two fixing rods 20, which are connected by bolts 21. Both fixing rods 20 are connected to the conveyor belt 4 using existing technology. The two fixing rods 20 are respectively connected to two support blocks 5, so that when the conveyor belt 4 is conveying, the fixing rods 20 can drive the support blocks 5 to follow the conveyor belt.

[0035] The second implementation method differs from the first implementation method in that: a guide groove 22 is provided on the mounting plate 2, and a round rod 23 is provided on the fixing rod 20 to fit and connect with the guide groove 22, which can guide the movement of the fixing rod 20 and the support block 5 and ensure the stability during transportation. During installation, one fixing rod 20 and round rod 23 are installed first, then the other one is installed, and finally the two fixing rods 20 are fixed together with bolts 21.

[0036] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0037] In use, the worker stands at the rear end of the conveyor belt 4 and places the guardrail tube onto the support block 5. Under the conveyor belt 4, the roller 6 rolls along the mounting plate 2, and the support block 5 moves with the conveyor belt 4. When it moves to the chamfering mechanism, the chamfering stops 13 on both sides are respectively fitted onto the two ends of the guardrail tube. Then, the pressure block 18 presses down and fixes the guardrail tube through the anti-slip pad 19, which allows the chamfering stops 13 to rotate and perform chamfering. After the chamfering is completed, the conveyor continues to convey the guardrail tubes on the rear side one by one. When the support block 5 conveys the guardrail tubes in the reverse direction, the chamfered guardrail tubes will fall off automatically.
