Description

Technical Field

[0001] This utility model relates to the field of pipe splicing tooling technology, and in particular to a complex hard pipe splicing welding tooling for hydraulic pipeline systems. Background Technology

[0002] In the rigid pipe welding technology of pipeline systems, rigid pipes need to be bent to varying degrees during the design due to spatial layout to meet the connection requirements of spatial dimensions. In many pipeline systems, rigid pipe bending is limited by space and other components, and there is a lack of understanding of the relevant performance of bending equipment. This can lead to complex pipeline spatial dimensions during the design, resulting in some spatial dimensions that cannot be measured during production and the inability to guarantee joint angles.

[0003] How to design a tooling to solve the technical problem of difficult welding of complex hard pipes in hydraulic pipeline systems is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The technical problem solved by this utility model is that traditional welding technology is prone to problems such as the inability to measure some spatial dimensions and the inability to guarantee the joint angle during production.

[0005] To solve the above-mentioned technical problems, the present invention provides a welding fixture for complex hard pipes in a hydraulic pipeline system, comprising:

[0006] The base plate module has multiple pre-drilled holes;

[0007] A fixing frame module, detachably connected to the surface of the base plate module, is used to connect the steel pipe welded joint of the rigid pipe;

[0008] A pipe support module, detachably connected to the surface of the base plate module, is used to support rigid pipes; and

[0009] A pipe connection plate positioning seat is detachably connected to the surface of the base plate module and is used to position the steel pipe connection plate of the rigid pipe.

[0010] The fixing frame module, the pipeline support module, and the pipeline connection plate positioning seat can be connected to the reserved holes at different positions of the base plate module to accommodate the installation of rigid pipes of different lengths and steel pipe welding joints of different angles.

[0011] Optionally, there are two fixing bracket modules, which are respectively connected to the two ends of the base plate module near the edge. Each fixing bracket module has a fixing bracket mounting hole and a steel pipe welding joint connection hole.

[0012] Optionally, the upper part of any of the fixing modules is bent toward the other fixing module.

[0013] Optionally, the upper portions of the two fixing modules are bent toward the other fixing module.

[0014] Optionally, there are two pipe support modules, which are respectively connected to the base plate module and located between the two fixing frame modules. Each pipe support module has a pipe support mounting hole and a bearing groove.

[0015] Optionally, the support groove is formed on top of the pipeline support module.

[0016] Optionally, the depth of the bearing groove in both of the pipeline support modules is the same.

[0017] Optionally, there are two pipe connection plate positioning seats, which are respectively connected to the base plate module and located between the two pipe support modules. Each pipe connection plate positioning seat has a positioning seat mounting hole and a positioning hole, and the positioning hole is equipped with a positioning pin.

[0018] Optionally, the two pipe connection plate positioning seats are at the same height.

[0019] The beneficial effects of this utility model's technical solution are:

[0020] This utility model provides a complex rigid pipe welding fixture for hydraulic pipeline systems. It can keep the pipes to be welded at the same height and different angles as required. Using this fixture for rigid pipe welding effectively eliminates the defects caused by complex pipeline dimensions in the design, which leads to unmeasurable spatial dimensions and inconsistent welding joint angles during production. This results in a solution capable of welding complex rigid pipes with bent spatial dimensions, fully meeting the diverse requirements of rigid pipe layout in hydraulic systems. Furthermore, the fixture has a simplified design, controlling the complex dimensions of the rigid pipes using the welding fixture, requiring only ordinary workers to operate, saving labor costs, improving production efficiency, and ensuring product dimensions.

[0040] In this embodiment, a pair of fixing bracket modules 2, a pair of pipe support modules 3, and a pair of pipe connection plate positioning seats 4 are installed on the base plate module 1.

[0041] More specifically, this embodiment adopts the following technical solution:

[0042] A complex rigid pipe welding fixture for a hydraulic pipeline system includes a base plate module 1, a fixing frame module 2, a pipeline support module 3, and a pipeline connection plate positioning seat 4. The base plate module 1 serves as the supporting base plate for the entire welding fixture.

The pipeline support module 3 supports the main body of the steel pipe. The pipeline connection plate positioning seat 4 supports and positions the welding position of the pipeline connection plate.

[0043] Preferably, the base plate module 1 is cut from a single piece of sheet material.

[0044] Preferably, the fixing frame module 2 is a V-shaped and T-shaped plate cut and welded from sheet metal, with a cross-section in the shape of a T and a V.

[0045] Preferably, the slot of the pipeline support module 3 is rectangular, and the edge has a chamfer R.

[0046] Preferably, the pipe connection plate positioning seat 4 is convex in shape and the left and right limiting holes are oblong in shape.

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] like Figures 1 to 4 As shown, a complex rigid pipe welding fixture in a hydraulic pipeline system includes a base plate module 1, a fixing frame module 2, a pipeline support module 3, and a pipeline connection plate positioning seat 4. The base plate module 1 serves as the supporting base plate for the entire welding fixture. The fixing frame module 2 positions the welding angle and dimensions of the steel pipe welding joint. The pipeline support module 3 clamps the steel pipe and positions the height difference between the steel pipe and the pipe. The pipeline connection plate positioning seat 4 clamps the steel pipe fixing plate and positions the welding position of the pipeline connection plate.

[0049] Pin holes are pre-drilled between each module. Each module is assembled according to the pre-drilled holes of the "base plate module 1" and the pre-drilled holes of other modules: pins are used to lock the "base plate module 1"; after the entire tooling is assembled, as shown in the "Assembly Drawing of Rigid Pipe Welding Tooling" in the attached summary, the rigid pipes are then welded: the steel pipe connecting plate is placed on the "pipe connecting plate positioning seat 4", and the waist-shaped hole on the connecting plate is aligned with the hole of the "pipe connecting plate positioning seat 4" and locked with waist-shaped pins. Then the steel pipe is placed on the connecting plate and in the slot of the "pipe support module 3"; the steel pipe welding joints are locked with pins on the front and rear "fixed frame modules 2" respectively. At this point, the entire steel pipe assembly is completed and welding begins.

[0050] In practice, a three-dimensional model is drawn based on the design drawings of the hydraulic rigid pipe, and corresponding welding fixture base plates and fixing frames of different heights are designed and drawn according to its spatial dimensions. The tooling and mold making personnel then produce the welding fixtures according to the drawings. Users simply place the corresponding rigid pipes and welding joint connectors in the appropriate positions to complete the welding; thereby significantly improving product quality, reducing production costs, increasing production efficiency, achieving significant economic benefits, and facilitating production line operation.

[0051] This utility model utilizes a rigid pipe welding fixture for rigid pipe welding, effectively eliminating the defects caused by complex pipeline space dimensions in the design, which leads to some space dimensions being unmeasurable and welding joint angles being unreliable during production. This results in an application capable of completing rigid pipe bending and complex space dimension welding, fully meeting the more diverse requirements of rigid pipe layout in hydraulic systems. Furthermore, the fixture is simple in design, controlling the complex dimensions of the rigid pipe using the welding fixture, requiring only ordinary workers to operate, saving labor costs; improving production efficiency and ensuring product dimensions.

[0052] In summary, this utility model provides a complex rigid pipe welding fixture for hydraulic pipeline systems. It can keep the pipes to be welded at the same height and different angles as required. Using this fixture for rigid pipe welding effectively eliminates the defects caused by complex pipeline dimensions in the design, which leads to unmeasurable spatial dimensions and inconsistent welding joint angles during production. This results in the ability to complete complex rigid pipe bending and welding, fully meeting the diverse requirements of rigid pipe layout in hydraulic systems. Furthermore, the fixture has a simplified design, controlling the complex dimensions of the rigid pipes, requiring only ordinary workers to operate, saving labor costs, improving production efficiency, and ensuring product dimensions.
