Bent pipe welding device

Abstract

The invention discloses a bent pipe welding device and belongs to the technical field of welding equipment. The bent pipe welding device comprises a material storage assembly, a welding assembly, clamping assemblies and a support assembly. The material storage assembly is fixedly installed above the support assembly and used for storing straight pipes, and the multiple clamping assemblies are evenly distributed on the circumference of the support assembly. The multiple clamping assemblies are driven by the support assembly to rotate, the clamping assemblies are used for clamping bent pipes, and the welding assembly used for welding the straight pipes and the bent pipes is arranged below the storage assembly. Through the special arrangement form of the storage assembly and the clamping assemblies, it is guaranteed that the straight pipes and the bent pipes are accurately aligned and automatically replaced, and the welding precision and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an elbow welding device. Background technique [0002] Metal pipe is a pipe formed of metal. Due to the characteristics of the pipe, a large number of bends are needed in the pipe. At present, there are many forming methods for metal bends, such as groove wheel rolling method and induction heating bending method. , Die bending method, step-by-step forming method, numerical control pipe bending method and welding forming method, among which welding forming method is also a relatively common forming method at present.

Problems solved by technology

[0003] In the processing of metal pipes, such as the processing of some auto parts, due to the small diameter of the pipe, spot welding is often used, and then the straight pipe end is clamped by a clamp with a rotating function, and then welded, but for The welding of metal pipes with large diameters is inconvenient due to their large volume and rotation. For this reason, manual welding is often used for welding, but the efficiency of manual welding is low, and good welding accuracy cannot be guaranteed at the same time. The publication number is CN113560805A The Chinese invention patent application discloses an elbow welding device for metal product processing, including a welding platform and an elbow clamping platform arranged on both sides of the welding platform. The welding platform includes a base and an annular support arranged on the top of the base. One side of the annular support is provided with an annular track, the annular track is provided with a slider, the slider is provided with a drive motor, the power end of the drive motor is connected with a drive gear, and the annular support is provided with There is a toothed ring meshing with the drive gear, the slider is also provided with a welding gun, and the elbow clamping platform is set in the shape of a five-degree-of-freedom mechanical arm. This prior art uses a ring-shaped welding platform to fix the pipe fittings , realize the automatic welding of metal pipe fittings, and realize the multi-angle clamping of metal pipe fittings by using the five-degree-of-freedom elbow clamping platform, because the prior art uses five-degree-of-freedom manipulators to clamp two pipe fittings to be welded And docking, the adjustment process needs to waste a lot of time. At the same time, it is necessary to carry out alignment and clamping operations on the two pipe sections before each welding, which is not efficient. Therefore, the invention provides an elbow welding device that can realize straight pipe welding. The automatic alignment and feeding of pipes and bends greatly improves the welding efficiency,
