Technical Field

[0001] The utility model relates to the technical field of pressure pipelines, in particular to a pressure pipeline bending mechanism. Background Art

[0002] Pressure piping refers to tubular equipment that uses a certain pressure to transport gas or liquid. The pressure pipeline is a part of the pipeline. The pipeline is used to transport, distribute, mix, separate, discharge, measure, control and stop the flow of fluids. It is an assembly consisting of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports.

[0003] The pressure pipe needs to be bent during the processing so that the pressure pipe can be used in different environments. At present, when the pressure pipe is bent, the pressure pipe is placed on a positioning table and positioned through matching connecting ears and bolts, and then the resistance end is driven by the output end of the hydraulic cylinder to resist the pipe, so that the pipe can complete the bending work after being stressed. However, this processing method has the following shortcomings when used: the pressure pipe is positioned through connecting ears and bolts during positioning, and the pressure pipe will slightly warp during bending, so that the bolts on the connecting ears will become loose, and the stability of the pressure pipe during bending cannot be guaranteed; and because no protective plate is set on the bending equipment, when the pressure pipe breaks during bending, this causes splashing at the broken part of the pressure pipe, and the bending equipment cannot protect the operator, which not only affects the efficiency of the pressure pipe bending processing, but also makes the operator's safety during operation cannot be guaranteed. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the stability of the pressure pipe cannot be guaranteed when it is bent, and proposes a pressure pipe bending mechanism.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A pressure pipe bending mechanism includes a bending device body, the bending device body includes a base 1, a hydraulic cylinder 2, a contact end 3, and a fixed rod 4. The output end of the hydraulic cylinder 2 drives the contact end 3 to contact the pipe, so that the pipe can cooperate with the fixed rod 4 to achieve bending. This technical solution is an existing technology and will not be elaborated on here.

[0022] A support plate and a vertical plate 6 are fixedly installed on the base 1, and a limit plate 5 extending to the support plate is fixedly installed on the fixed rod 4. The vertical plate 6 is vertically arranged at the positions on both sides of the abutment end 3. The limit plate 5 is threadedly connected with locking bolts corresponding to the support plate. A guide plate 7 for guiding the pipeline is installed on the vertical plate 6. Before the pipeline is bent, the specifications of the fixed rod 4 are first selected, and the fixed rod 4 is a rectangular parallelepiped or a cylinder, so that the bending part of the pipeline can be adjusted according to the specifications of the fixed rod 4, and the two vertical plates 6 can protect the bent pipeline, thereby protecting the operator next to the base 1, and the deflected pipeline can be guided by the two guide plates 7;

[0023] The base 1 is provided with an integrally connected ring frame 8 and a bracket 9, a symmetrically arranged sleeve 10 is fixedly mounted on the ring frame 8, and a clamp assembly for preliminary clamping of the pipeline is installed in the sleeve 10;

[0024] The clamp assembly includes a pressure rod 11 slidably sleeved in a sleeve 10, and a spring 12 is welded between the pressure rod 11 and the sleeve 10. A clamping plate 13 corresponding to the pipe is fixedly mounted on the pressure rod 11. The sleeve 10 guides the pressure rod 11 so that the pressure rod 11 can smoothly pull the clamping plate 13 when moving. The spring 12 resets the clamping plate 13. When the clamping plate 13 is in an unloaded state, the spring 12 can drive the clamping plate 13 back to its initial position.

[0025] The clamping plate 13 and the pressure rod 11 extend to the lower end position in the ring frame 8, and the spring 12 is vertically arranged. The clamping plate 13 is an arc-shaped structure adapted to the pipeline, and one end of the pipeline is extended into the ring frame 8 through the bracket 9. When one end of the pipeline extends into the ring frame 8, the two clamping plates 13 can initially limit the pipeline;

[0026] A symmetrically arranged fixing frame is fixedly mounted on the bracket 9, and a limiting component for limiting the position of the pipeline is installed on the fixing frame;

[0027] The limit assembly includes a motor 14 fixedly mounted on a fixed frame, and a screw rod 15 is fixedly connected to the output end of the motor 14, a screw rod 16 is rotatably mounted on the fixed frame and is transmission-connected to the screw rod 15, and matching nuts 18 are slidably sleeved on the screw rods 15 and 16, and a moving plate 19 is fixedly mounted on the nut 18, and a clamping plate 20 that is movable against the pipeline is fixedly mounted on the moving plate 19;

[0028] The screw rod 15 and the screw rod 2 16 are arranged horizontally, and a transmission belt 17 is connected between the screw rod 15 and the screw rod 2 16. A long hole for guiding the movable plate 19 is provided in the bracket 9, and the clamping plate 20 is an arc-shaped structure corresponding to the pipeline. The transmission belt 17 adopts a synchronous belt, which has the advantages of compact structure and non-slip, so that the screw rod 15 and the screw rod 2 16 can be driven at the same speed, and the long hole guides the movable plate 19, thereby limiting the moving direction of the nut 18;

[0029] By setting the clamping plate 13 and the clamping plate 20 to an arc-shaped structure that is compatible with the pipeline, the contact area between the clamping plate 13, the clamping plate 20 and the pipeline is increased, and the screw rod 15 is driven to rotate by the output end of the motor 14, so that the two groups of clamping plates 20 limit the pipeline from both sides, so that the stability of the pipeline during processing is guaranteed, and the efficiency of pipeline processing is effectively improved.

[0030] The functional principle of the utility model can be explained through the following operation modes:

[0031] Extend one end of the pipeline through the bracket 9 into the ring frame 8;

[0032] After the pipe enters the ring frame 8, it will resist the two clamping plates 13, and the clamping plates 13 drive the pressure rod 11 to slide in the sleeve 10, and the spring 12 is stressed, so that the two clamping plates 13 can initially limit the pipe;

[0033] The output end of the motor 14 drives the screw rod 15 to rotate, and the screw rod 15 drives the screw rod 2 16 to rotate through the transmission belt 17. When the screw rods 15 and 16 rotate, they drive the nut 18 to move, so that the nut 18 drives the moving plate 19 to slide in the long hole, and the moving plate 19 drives the clamping plate 20 to clamp the pipe from both sides.

[0034] The fixing rod 4 is selected according to the pipe bending position, the limiting plate 5 equipped with the fixing rod 4 is extended to the support plate, and the limiting plate 5 and the support plate are connected with the locking bolt;

[0035] The output end of the hydraulic cylinder 2 drives the abutment end 3 to extend and retract, so that the abutment end 3 applies pressure to the other end of the pipe, and the pipe can be guided by two guide plates 7 when deflected;

[0036] After the pipe is processed, the clamping plate 20 returns to the initial position and the bent pipe is removed.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
