Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a multi-angle hydraulic electric pipe bending machine. Background Art

[0002] Multi-angle hydraulic electric pipe bender is a special equipment for bending metal pipes. It can bend metal pipes to achieve different angles and different radiuses. The pipe bender can accurately control the angle and radius of the pipe to ensure the processing accuracy and quality. The pipe bender adopts a hydraulic electric system, which makes the pipe bender have the characteristics of automated production. It can realize automatic pipe bending by setting the program, improve production efficiency, reduce manual operation, and reduce labor intensity.

[0003] The multi-angle hydraulic electric pipe bender transmits the metal pipe through the hydraulic electric system, so that the metal pipe is transmitted to one side of the pipe bending die. At this time, the metal pipe is extruded and bent under the action of the pipe bending die and the extrusion assembly, so that the metal pipe can complete the processing of different angles and different radii. As the number of times the pipe bending die is used increases, the pipe bending die will wear or deform, affecting the forming quality of the bent pipe. The staff needs to check the wear of the pipe bending die and replace it in time. Since the pipe bending die is generally installed with multiple fastening bolts and fasteners, it takes a certain amount of time for the staff to replace the pipe bending die, which makes it inconvenient for the pipe bending machine to quickly replace the pipe bending die. Therefore, we propose a multi-angle hydraulic electric pipe bender. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-angle hydraulic electric pipe bending machine, comprising a pipe bending machine body and a hydraulic electric component, the hydraulic electric component is installed on the upper side of the pipe bending machine body, and a workbench is fixed on one side of the pipe bending machine body, an extrusion component is installed on the outer side of the workbench, a pipe bending mold is arranged on the upper side of the workbench, and a docking block is fixed on the lower side of the pipe bending mold, a docking groove is provided on the side of the workbench close to the docking block, and the docking block is connected to the docking groove, slots are respectively provided on both sides of the docking block, and the slots are connected to the limit rod, and the workbench is provided with a storage groove on the outer side of the limit rod.

[0006] Preferably, the receiving groove is slidably docked with the limiting rod, the inner side of the limiting rod is docked with the limiting screw, and the limiting screw is movably connected with the receiving groove via a bearing.

[0007] Preferably, a sliding block is fixed to the outer side of the limiting rod, and the receiving groove is provided with a sliding groove on the outer side of the sliding block, and the sliding groove is slidably docked with the sliding block.

[0008] Preferably, a first bevel gear is fixed to one end of the limiting screw, and the first bevel gear is connected to the first bevel gear assembly frame.

[0009] Preferably, one end of the first bevel gear frame away from the first bevel gear is connected to the second bevel gear frame, and a second bevel gear is connected between the two second bevel gear frames.

[0012] Preferably, a bracket is fixed on the upper side of the limit block, and a baffle is fixed on the upper end of the bracket.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the multi-angle hydraulic electric pipe bender, by rotating the knob, the two limit rods are retracted into the storage groove along the limit screw, and the knob is rotated in the opposite direction to make the limit rods extend out of the storage groove again to dock with the slot, so that the staff can quickly install the pipe bending mold, and the multi-angle hydraulic electric pipe bender is easy to quickly replace the pipe bending mold. The baffle shields the upper part of the joint between the extrusion assembly and the pipe bending mold and the metal pipe, so that the staff and the metal pipe can maintain a safe distance from the multi-angle hydraulic electric pipe bender to prevent pinching or collision accidents.

[0014] 1. The multi-angle hydraulic electric pipe bender transmits the metal pipe through the hydraulic electric system, so that the metal pipe is transmitted to one side of the pipe bending die. At this time, the metal pipe of the extrusion assembly is bent under the action of the pipe bending die and the extrusion assembly, so that the metal pipe is processed at different angles and different radii. When the staff needs to replace the pipe bending die, the knob is rotated so that the two limit rods are retracted into the storage groove along the limit screw.
