Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe bending, in particular to pipe bending equipment used in construction engineering. Background Art
[0002] Metal pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. Pipes are also necessary materials for construction projects. Commonly used ones are water pipes, drainage pipes, gas pipes, heating pipes, wire ducts, rainwater pipes, etc. In addition, there are pipes used in guardrails, that is, guardrail pipes. In the production and processing of guardrail pipes, the pipes are often bent into different shapes according to aesthetic needs, which requires the use of a bending machine.
[0003] Traditional pipe bending equipment requires the iron pipe to be bent to pass through a hand rod, and the front end is put on the iron column of the fixed sleeve, and the hand rod is rotated. The limit block on the hand rod and the groove of the disc squeeze the iron pipe. During the rotation, the iron rod is gradually bent. It can be seen that the bending method of traditional equipment leads to the inability to well define the position of the pipe during the bending process. When the pipe is bent, the operator will press one end of the workpiece with his hand to prevent the workpiece from moving. When the operator holds the workpiece at a close distance, the iron filings generated are easy to splash, which brings danger to the operator and reduces the practicality of the pipe bending equipment. In addition, some bending machines use hard bending when in use. When bending, the bending part contacts the metal pipe with hard contact. When the metal pipe is bent, the bending part contacts the bending block, which will cause slight wear and tear, resulting in scratches on the bending part. Utility Model Content

The fixing component includes a pad 6, the upper surface of the pad 6 is fixedly connected to the lower surface of the workbench 1, and a fixing screw 7 is fixedly connected inside the pad 6, and a threaded fixing block 10 is fixedly connected to the lower surface of the pad 6, the outer wall of the bidirectional threaded rod 8 is threadedly connected to the inner wall of the threaded fixing block 10, and a splint 5 is fixedly connected to one side of the outer wall of the U-shaped fixing plate 4.
[0023] Specifically, the first motor 13 is started to drive the belt 12, and the rotation of the belt 12 drives the bidirectional threaded rod 8 to rotate. The internal spiral rotating tube 9 of the U-shaped fixed plate 4 is threadedly connected to the bidirectional threaded rod 8 and one side of its outer wall is fixedly connected to the slider 3. Under the rotation of the bidirectional threaded rod 8 and the spiral rotating tube 9, and the sliding action of the slider 3 and the slide rail 2, the U-shaped fixed plate 4 moves left and right, thereby driving the clamping plate 5 on the U-shaped fixed plate 4 to move left and right, thereby achieving the clamping and positioning of the pipe, preventing the tail of the pipe from shaking in position when the pipe is bent, which causes the pipe to be bent and collapsed, and improves the safety during bending.
[0024] Reference Figure 1-3 A fixed circular plate 15 is fixedly connected to the upper surface of the workbench 1, a second motor 16 is fixedly connected to the upper surface of the fixed circular plate 15, a processing plate 17 is rotatably connected to the output end of the second motor 16, a bending wheel 18 is fixedly connected to the upper surface of the processing plate 17, a cylinder 19 is fixedly connected to the upper surface of the processing plate 17, and a bending head 20 is fixedly connected to the output end of the cylinder 19.
[0025] Specifically, the cylinder 19 is started, and the bending head 20 is stuck on the outside of the steel structure pipe under the pushing action of the cylinder 19, and then the second motor 16 is started to drive the processing plate 17 to rotate, and then the bending wheel 18 and the bending head 20 on the processing plate 17 are driven to rotate. At the same time, under the interaction of the bending wheel 18 and the bending head 20, the pipe is bent along the outside of the bending wheel 18, so that the bending of the steel structure pipe is quickly completed, and the bending quality is improved.

Then start the second motor 16 to drive the processing plate 17 to rotate, and then drive the bending wheel 18 and the bending head 20 on the processing plate 17 to rotate. At the same time, under the interaction of the bending wheel 18 and the bending head 20, the construction pipe is finally bent along the outside of the bending wheel 18.
