Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe bending, in particular to a steel pipe bending device which is convenient for loading and unloading. Background Art

[0002] Bending is a common processing technology in the process of steel pipe processing. At present, a bending machine is generally used in the bending process of steel pipes. For example, patent CN211386426U discloses a bending machine for steel pipe processing. When bending the steel pipe, one end of the steel pipe is passed through the limiting hole on the limiting block, and then placed in the bending groove on the fixed wheel and the guide wheel, and the scale line at the movable groove measures the length of the steel pipe to be bent. After measuring the appropriate length, the first screw is rotated to limit the positioning plate on one end of the steel pipe, and finally the second screw is rotated to fix the steel pipe by the second clamping plate. After the power is turned on, the driving motor drives the active gear to rotate, thereby driving the driven gear to rotate, and finally the bending turntable rotates to bend the steel pipe.

[0003] However, the above patented technology still has some problems in actual use. For example, when loading, one end of the steel pipe needs to be passed through the limit hole on the limit block. This process requires manual holding of the steel pipe to align with the limit hole without deviation. The operation requirements are high, and the steel pipe needs to be manually removed from the machine after bending. The processing efficiency is also low, so it needs to be improved.

DETAILED DESCRIPTION

[0018] 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.

[0019] like Figure 1-2 As shown, the steel pipe bending device for convenient loading and unloading of materials in this embodiment includes a workbench 1, a loading roller 2, a guiding mechanism 3, a driving mechanism 4, a bending mechanism 5 and a receiving mechanism 6; the loading rollers 2 are arranged at intervals in the horizontal direction of the workbench 1, so that the steel pipe can be rolled and transported along the loading rollers 2 when loading; the guiding mechanism 3 is supported and arranged above the loading rollers 2, and is used for clamping, positioning and transporting the steel pipe; the driving mechanism 4 is arranged on one side of the loading roller 2, and is used for driving the steel pipe to move, so as to transport it to the bending mechanism 5; the bending mechanism 5 is arranged on one side of the driving mechanism 4, and is used for bending the steel pipe; the receiving mechanism 6 is arranged at the unloading end of the workbench 1, and is used for collecting the bent steel pipe.

[0020] The guide mechanism 3 includes a group of guide rods 31 symmetrically arranged along the central axis of the workbench 1. One end of the guide rod 31 is arranged above the workbench 1 through a rotating support 32, and the guide rod 31 is connected to the rotating support 32 through a torsion spring 33. The other end of the guide rod 31 is provided with a guide wheel 34. When the steel pipe is loaded, under the action of the torsion spring 33, the steel pipe is clamped and transported by two guide wheels 34 to prevent the steel pipe from running off. There is no need to deliberately align the drive mechanism 4. The guide mechanism 3 will naturally guide the steel pipe, thereby improving the loading efficiency.

[0021] The driving mechanism 4 includes a group of driving wheels 41 symmetrically arranged along the central axis of the workbench 1. A driving motor 42 is provided at the bottom of the workbench 1, and the driving motor 42 is connected to one of the driving wheels 41. The driving motor 42 drives one of the driving wheels 41 to rotate, and the spacing between the two driving wheels 41 matches the outer diameter of the steel pipe, so the steel pipe can be clamped and transported forward by the two driving wheels 41; under the joint action of the guiding mechanism 3 and the driving mechanism 4, it can be ensured that the steel pipe is always transported forward along the central axis of the workbench 1.

[0022] The bending mechanism 5 includes a positioning block 51 and a pushing unit 52. The positioning block 51 is arranged on one side of one of the driving wheels 51, and the pushing unit 52 is arranged on one side of the other driving wheel 41. The positioning block 51 and the pushing unit 52 are staggered, and a bending block 53 is arranged at the front end of the pushing unit 52. Among them, the pushing unit 52 can adopt an air cylinder or an oil cylinder, and the bending block 53 can adopt a roller or a block structure with a relatively smooth surface to facilitate the bending of the steel pipe and avoid damaging the steel pipe. The different shapes and angles of the positioning block 51 can bend steel pipes with different angles.

[0023] The material receiving mechanism 6 includes a material receiving box 61, a material receiving plate 62 is arranged in the material receiving box 61, and a buffer assembly is arranged at the bottom of the material receiving plate 62; the buffer assembly includes a connecting rod 63, a sliding rod 64, a slider 65 and a buffer spring 66, the sliding rod 64 is arranged at the bottom of the material receiving box 61, and a slider 65 is slidably arranged on both sides of the sliding rod 64, and the sliders 65 on both sides are rotatably connected to the material receiving plate 62 through the connecting rod 63 respectively, and a buffer spring 66 is sleeved on the outer side of the sliding rod 64 at the position between the slider 65 and the inner wall of the material receiving box 61, and a buffer pad 67 is also provided on the top of the material receiving plate 62, and the buffer pad 67 can be made of flexible materials such as rubber, silicone, sponge, etc. to prevent damage to the steel pipe.

[0024] The steel pipe after bending in the front falls into the receiving box 61 under the push of the subsequent steel pipe. As more and more steel pipes are in the receiving box 61, the receiving plate 62 is gradually pressed down, so that the internal space of the receiving box 61 gradually becomes larger to accommodate more steel pipes.

[0025] After the steel pipes are taken out one after another, under the reset action of the buffer spring 66, the receiving plate 62 is gradually pushed up to lift the steel pipes, making it easier for the staff to take them out, saving physical effort and time.

[0026] To sum up, the steel pipe bending device of the utility model guides the loading of steel pipes through the loading roller 2 and the guiding mechanism 3, and transports the steel pipes to the bending mechanism 5 through the driving mechanism 4, and then bends the steel pipes through the bending mechanism 5, and finally collects the bent steel pipes through the receiving mechanism 6, thereby conveniently realizing the loading, bending and unloading of steel pipes, and effectively improving the bending processing efficiency of steel pipes.
