Description

Technical Field

[0001] The utility model relates to the technical field of guardrail processing, in particular to a metal guardrail cold processing corner bending machine. Background Art

[0002] Metal guardrail refers to a general term for guardrails made of metal materials. This type of guardrail is widely used in roads, railways, bridges, airports, stadiums and other places due to its high strength, corrosion resistance, fatigue resistance, and non-deformation properties. In the production process of metal guardrails, it is often necessary to bend and cold-process the metal material to form a specific shape and structure to meet the actual use needs of the guardrail.

[0003] The existing patent with publication number CN218050012U provides a metal guardrail corner bending device, which can realize efficient bending operation of metal guardrails through the setting of bending frame, limit frame, rotating shaft seat, limit seat, bending seat, anti-skid gear ring, first damping shaft, stabilizing frame, second damping shaft and rotating top frame. In actual use, the staff first clamps the two ends of the bending part of the metal guardrail that needs to be bent in the limit seat and performs preliminary limiting by twisting the clamping bolt inside the clamping seat, and then folds the stabilizing frame and the rotating top frame to a vertical state respectively, stably covers the bending seat, and then starts the bending cylinder and the bending seat, and performs stable metal guardrail bending work under the limiting top fixing of the bending push rod and the anti-skid gear ring. During the bending process, the two ends of the bending part of the metal guardrail can be stably and adaptively adjusted inside the limit seat, and at the same time, the overall limiting operation is performed in conjunction with the stabilizing frame and the rotating top frame, so that the bending process is more stable, which reflects the practicality of the equipment design.

[0004] However, in the above technical solution, although the two ends of the metal guardrail can be clamped and fixed by twisting the locking bolt inside the locking seat, the distance between the two locking seats is relatively fixed, and the length of the metal guardrail may be long or short. The locking seats with difficult-to-adjust spacing may not be able to clamp and fix the metal guardrail that is too short, thereby limiting the possibility of the device to bend some metal guardrails that are too short. Therefore, the utility model aims to provide a bending machine that can adjust the distance between the two locking seats. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a metal guardrail cold processing corner bending machine, which can adjust the distance between two clamping seats to solve the problem in the prior art that it is difficult to adjust the distance between the two clamping seats, making it difficult for the device to bend metal guardrails that are too short.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a metal guardrail cold processing corner bending machine, including an operating table, a guardrail body and a bending cylinder arranged on the operating table, and also includes a limiting seat, which is arranged on one end of the operating table located at the output end of the bending cylinder, and two movable seats are relatively spaced apart on the limiting seat; a rotating seat, which is rotatably arranged on the movable seat, and the movable seat is provided with a clamping mechanism for clamping and fixing the guardrail body; and a driving mechanism, which is arranged between the limiting seat and the movable seat, and drives the two movable seats to be relatively close or far away, so as to increase or decrease the distance between the two movable seats.

[0012] Compared with the prior art, the utility model provides a metal guardrail cold processing corner bending machine, which has the following beneficial effects:

[0013] The utility model adjusts the distance between the two moving seats through a driving mechanism until the distance is suitable for the length of the fence body, and then uses the clamping mechanisms on the two rotating seats to clamp and fix the two ends of the fence body, so that users can clamp fence bodies of different lengths.

[0014] The utility model provides a friction increasing groove.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a metal guardrail cold processing corner bending machine, comprising an operating table 1, a guardrail body 2 and a bending cylinder 3 arranged on the operating table 1, and also comprising a limiting seat 4, which is arranged on the operating table 1 at one end of the output end of the bending cylinder 3, and two movable seats 5 are relatively spaced apart on the limiting seat 4; a rotating seat 6, which is rotatably arranged on the movable seat 5, and a clamping mechanism 7 for clamping and fixing the guardrail body 2 is provided on the movable seat 5; and a driving mechanism 8, which is arranged between the limiting seat 4 and the movable seat 5, and drives the two movable seats 5 to be relatively close or far away, so as to increase or decrease the distance between the two movable seats 5.

[0024] When the user needs to bend the fence body 2 using the metal guardrail cold processing corner bending machine, he first adjusts the distance between the two movable seats 5 through the driving mechanism 8 until the distance is suitable for the length of the fence body 2, and then uses the clamping mechanism 7 on the two rotating seats 6 to clamp and fix the two ends of the fence body 2, so that the user can clamp the fence bodies 2 of different lengths.

[0025] In this embodiment, the clamping mechanism 7 includes two clamping plates 9 and a bolt 10. A T-shaped clamping groove 11 is provided on the rotating seat 6. A T-shaped sliding block 12 is protruded from the bottom of the clamping plate 9. The sliding block 12 is movably arranged in the clamping groove 11. The bolt 10 is threadedly connected to the two clamping plates 9. When the user needs to clamp and fix the fence body 2, the user first places the fence body 2 between the two clamping plates 9, then uses the bolt 10 to bring the two clamping plates 9 relatively close, and finally fixes the two clamping plates 9 so that the clamping plates 9 can clamp and fix the fence body 2.

[0026] In this embodiment, the two clamping plates 9 are movably penetrated by a guide rod 13, and a limit portion 14 is provided at both ends of the guide rod 13. A spring 15 is sleeved at both ends of the guide rod 13, and the spring 15 elastically abuts the clamping plates 9; when the user needs to clamp and fix the fence body 2, the two clamping plates 9 are first opened to the opposite sides, and then the fence body 2 is placed between the two clamping plates 9. At this time, the two clamping plates 9 are released, and the two clamping plates 9 will automatically be elastically abutted by the spring 15 located on the guide rod 13 to clamp the fence body 2, eliminating the need for the user to manually move the two clamping plates 9 closer to each other, thereby improving the user's clamping efficiency of the fence body 2.

[0027] In this embodiment, a plurality of friction-increasing grooves 16 are provided on the clamping plate 9 at intervals along its height direction; when the two clamping plates 9 clamp the fence body 2, the friction-increasing grooves 16 on the clamping plates 9 will increase the friction force of the clamping plates 9 on the fence body 2, thereby increasing the stability of the clamping plates 9 when clamping the fence body 2.

[0028] In this embodiment, the driving mechanism 8 includes a double-headed screw 17, a movable groove 18 is provided on the limiting seat 4 along its length direction, and a movable block 19 is formed on the bottom of the movable seat 5. The movable block 19 is arranged in the movable groove 18, and the double-headed screw 17 is rotatably arranged in the movable groove 18. The movable block 19 is sleeved on the double-headed screw 17 and is threadedly connected with the double-headed screw 17; when the user needs to adjust the spacing between the two movable seats 5, by rotating the double-headed screw 17, the forward or reverse rotation of the double-headed screw 17 will drive the two movable blocks 19 to move in similar or opposite directions, so that the user can adjust the spacing between the two movable seats 5.

[0029] In this embodiment, the double-headed screw 17 is driven to rotate by a motor 20, and the motor 20 is electrically connected to an external power source through a controller; when the user needs to rotate the double-headed screw 17, the controller controls the forward or reverse rotation of the motor 20 to drive the screw to rotate forward or reverse, thereby improving the efficiency of the user when rotating the double-headed screw 17.

[0030] Working principle: When the user needs to bend the fence body 2, first turn the double-headed screw 17. The forward or reverse rotation of the double-headed screw 17 will drive the two moving blocks 19 to move in similar or opposite directions, so that the user can adjust the distance between the two moving seats 5 until the distance is suitable for the length of the fence body 2, and then place the fence body 2 between the two clamping plates 9, and then use the bolts 10 to bring the two clamping plates 9 relatively close, and finally fix the two clamping plates 9 so that the clamping plates 9 can clamp and fix the fence body 2, which is convenient for the user to clamp fence bodies 2 of different lengths; when the user needs to clamp and fix the fence body 2, first break the two clamping plates 9 toward the opposite sides, and then place the fence body 2 Between the two clamping plates 9, the two clamping plates 9 are released at this time, and the two clamping plates 9 will automatically be elastically abutted by the spring 15 located on the guide rod 13 to clamp the fence body 2, eliminating the need for the user to manually move the two clamping plates 9 closer together, thereby improving the user's clamping efficiency of the fence body 2; when the two clamping plates 9 clamp the fence body 2, the friction-increasing grooves 16 located on the clamping plates 9 will increase the friction force of the clamping plates 9 on the fence body 2, thereby increasing the stability of the clamping plates 9 when clamping the fence body 2; when the user needs to rotate the double-headed screw 17, the controller controls the forward or reverse rotation of the motor 20 to drive the screw to rotate forward or reverse, thereby improving the efficiency of the user when rotating the double-headed screw 17.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
