Description

Technical Field

[0001] This utility model relates to the field of bending devices, and in particular to a bending device for the production and processing of guardrail profiles. Background Technology

[0002] As an important safety protection facility, guardrails are widely used in various places such as residences, highways, commercial areas, and public places. They play a key role in protecting personal safety and equipment facilities. Guardrails not only have practical functions, but also beautify the environment and enhance the landscape effect. The processing of guardrail profiles is an important part of guardrail production, among which the bending device plays a crucial role.

[0003] Existing bending devices for guardrail profile production and processing are typically hydraulically driven. They use hydraulic pressure to press down on bending plates or columns to squeeze and turn the guardrail profiles, causing them to bend into various shapes such as U-shape, V-shape, and L-shape.

[0004] On the one hand, existing bending devices for guardrail profile production and processing typically use threaded rods to compress clamping blocks to fix the ends of the guardrail profiles. This requires manual repeated rotation of bolts to loosen the fixing, making it impossible to quickly clamp and loosen the guardrail profiles, resulting in reduced production efficiency. On the other hand, existing bending devices for guardrail profile production and processing require manual loosening and re-clamping of the guardrail profiles, thereby changing the position of continuous bending of the guardrail profiles and making it impossible to drive the guardrail profiles to move autonomously. Therefore, a bending device for guardrail profile production and processing is proposed to solve the above problems. Utility Model Content

A motor 2 is fixedly connected to the bottom of the outer wall of the table body 1. The motor 2 is prior art and will not be described in detail. It is used to drive a gear 3 to rotate a gear 4. The output shaft of the motor 2 is fixedly connected to the gear 3. The inner side of the outer wall of the gear 3 is meshed with the gear 4. The gear 3 and the gear 4 have different gear ratios, which are used to reduce the speed of the bending plate 6 and increase the torque. A rotating shaft 5 is fixedly connected to the center of the inner wall of the gear 4. The rotating shaft 5 is used to connect the gear 4 and the bending plate 6 and provide the origin of rotation for the bending plate 6. The top of the outer wall of the rotating shaft 5 is fixedly connected to the bending plate 6. The bending plate 6 is L-shaped and the bottom is used to place... The guardrail profile is placed on the side wall, which is used to bend the guardrail profile by pressing it. A pulley 7 is rotatably connected to the inner wall of the bending plate 6. The pulley 7 reduces the friction of the guardrail profile and prevents direct contact with the bending plate 6 from causing wear. A fixed base 8 is fixedly connected to the top of the outer wall of the table body 1. The fixed base 8 provides a fixed moving point for the clamping plate 12 and a hinged unfolding point for the connecting rod 9. A connecting rod 9 is hinged to the end of the outer wall of the fixed base 8. There are four sets of connecting rods 9 in total. Two sets are set on one side, one above the other, for unfolding or retracting via a linkage component. Two sets of connecting rods 9 are also provided, and a connecting rod 10 is fixedly connected between the two sets of connecting rods 9. The connecting rod 10 is used to move the upper and lower sets of connecting rods 9 simultaneously via a linkage component. A linkage component is provided on the outer wall of the connecting rod 10.

[0034] Reference Figures 2-4 A slider 11 is hinged to the outer end of the connecting rod 9. The slider 11 is T-shaped and is used to engage with the slide groove 13 to keep the connecting rod 9 always unfolded along the slide groove 13, so that the clamping plate 12 moves with the unfolding distance of the connecting rod 9. The table body 1 is slidably connected to the outer wall of the clamping plate 12. The clamping plate 12 is used to cooperate with the fixing frame 19 to clamp the guardrail profile. A slide groove 13 is opened on the back of the outer wall of the clamping plate 12. The slide groove 13 is concave T-shaped and is used to engage with the slider 11 to keep the slider 11 moving stably along the slide groove 13. An auxiliary block 14 is fixedly connected to the bottom of the outer wall of the clamping plate 12. The auxiliary block 14 is T-shaped and is used to engage with the slide groove 13 to keep the slider 11 moving stably along the slide groove 13. The clamping plate 12 is kept stable and moves back and forth by the locking auxiliary groove 15. The top of the outer wall of the table body 1 is provided with an auxiliary groove 15. The auxiliary groove 15 is set with a concave T-shape to lock the auxiliary block 14 and keep the auxiliary block 14 moving stably along the auxiliary groove 15. The outer wall of the rotating shaft 5 passes through and is slidably connected to the inner wall of the table body 1. The bottom of the outer wall of the bending plate 6 is slidably connected to the top of the outer wall of the table body 1. The bottom of the outer wall of the connecting rod 9 is slidably connected to the top of the outer wall of the table body 1. The end of the outer wall of the slider 11 is slidably connected to the inner wall of the slide groove 13. The outer wall of the auxiliary block 14 is slidably connected to the inner wall of the auxiliary groove 15.

[0035] Reference Figures 3-5A fixed frame 19 is fixedly connected to the top of the outer wall of the table body 1. The fixed frame 19 is used as a fixed clamping block to provide a fixed clamping surface for the guardrail profile. A motor 20 is fixedly connected to the top left side of the outer wall of the fixed frame 19. The motor 20 is existing technology and will not be described in detail. It is used to drive the roller 22 to move the guardrail profile. A sprocket 21 is fixedly connected to the output shaft of the motor 20. The sprocket 21 is used to drive multiple sets of rollers 22 to rotate through the chain 23. Rollers 22 are fixedly connected to the bottom of the outer wall of the sprocket 21. The rollers 22 can be made of soft rubber material and are used to drive the guardrail profile to move through the motor 20. There are several sets of sprockets 21. The sets of sprockets 21 are connected to each other through the chain 23. The outer wall of the roller 22 is rotatably connected to the inner wall of the fixed frame 19.

[0036] Reference Figures 4-6 The linkage component includes a retaining ring 16, the inner diameter of which is smaller than the outer diameter of the connecting rod 10, so that the retaining ring 16 maintains a fixed height. The inner wall of the retaining ring 16 is engaged and slidably connected to the outer wall of the connecting rod 10. The end of the retaining ring 16 is connected to a threaded sleeve 18 through a threaded rod 17. The threaded sleeve 18 is used to rotate the two sets of threaded rods 17 in both directions to rotate and unfold or retract simultaneously. There are two sets of threaded rods 17, which are connected to each other through the threaded sleeve 18. The two sets of threaded rods 17 are provided with opposing threads to shorten the thread distance of a single threaded rod 17 and accelerate the clamping and loosening operation. The bottom end of the outer wall of the threaded rod 17 is rotatably connected to the inner wall of the end of the retaining ring 16, and the two ends of the inner wall of the threaded sleeve 18 are threadedly connected to the inner side of the outer wall of the two sets of threaded rods 17.

[0037] Working principle: When clamping the guardrail profile, the guardrail profile is placed on the top of the table body 1 and attached to the roller 22. By manually rotating the threaded sleeve 18, the two sets of threaded rods 17 are driven to retract inward. Then, the threaded rods 17 drive the slider 11 to move along the middle of the slide groove 13. After that, the slider 11 drives the clamping plate 12 to move forward along the direction of the auxiliary groove 15, so that the clamping plate 12 contacts and adheres to the guardrail profile, and the guardrail profile adheres to the outer wall surface of the roller 22. This shortens the thread distance of a single threaded rod 17, achieves the effect of quick clamping and loosening, and improves production and processing efficiency.

[0038] During continuous bending of the guardrail profile, the motor 20 is manually controlled to briefly drive the sprocket 21 to rotate. The sprocket 21 drives the roller 22 to rotate, and the chain 23 drives multiple sets of rollers 22 to rotate simultaneously. The rollers 22 then move the guardrail profile forward a short distance to the continuous bending point. The motor 2 then drives the gear 3 to rotate, which in turn drives the gear 4 to rotate. The gear 4 then drives the shaft 5 to rotate, which in turn drives the bending plate 6 to rotate. The bending plate 6 drives the pulley 7 to squeeze the guardrail profile, bending it at the required angle. This allows the guardrail profile to be moved in a non-loose state, improving the efficiency of continuous bending of the guardrail profile.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
