Description

Technical Field

[0001] The invention relates to the technical field of gas pipe processing, and in particular to a gas pipe connector buckling and bundling pipe sealing process. Background Art

[0002] The traditional manufacturing process in the industry is: bending pipe forming - inserting pipe joints (lathe processing parts) - putting them into fixtures - manual brazing (oxygen heating copper welding wire and then blowing welding evenly) - pickling (pretreatment) - electrophoresis treatment. This method of preparing gas pipes is costly and inefficient, so improvements are made. Summary of the invention

[0003] The present invention aims at the defects of the prior art such as slow preparation speed of gas pipes, and provides a new gas pipe connector crimping and bundling sealing process.

[0004] In order to solve the above technical problems, the present invention is implemented by the following technical solutions:

[0005] A gas pipe connector buckling and bundling pipe sealing process comprises the following steps:

[0006] S1. Take the bent pipe and put it into the main clamping seat assembly;

[0007] S2. The processing module moves close to both ends of the elbow, and the auxiliary clamping device on the processing module clamps both ends of the elbow, and reserves the pipe sections to be processed at both ends;

[0008] S3. A tapered reaming assembly is provided in the processing module, and the reaming member provided in the tapered reaming assembly is inserted into the pipe section to be processed so that the pipe section to be processed forms a 55°-65° reaming inclined guide pipe section;

[0009] S4. The taper reaming assembly is withdrawn, the auxiliary clamping device releases the bent pipe, and the processing module moves away from the bent pipe;

[0010] S5. Place the connector on the assembly module assembly;

[0011] S6. The assembly module is close to both ends of the elbow, and the auxiliary clamping device 2 is provided on the assembly module to clamp both ends of the elbow;

[0012] S7. Install the assembly to press the connector into both ends of the elbow to form a semi-finished gas pipe;

[0013] S8. The placement assembly is withdrawn, the auxiliary clamping device 2 releases the elbow, and the assembly module is away from the semi-finished gas pipe;

[0014] S9. The buckle tube assembly is close to both ends of the semi-finished gas pipe, and the buckle tube assembly presses the inclined guide pipe section so that the inner walls of both ends of the bent pipe are close to the connector to form a finished gas pipe;

[0015] S10. The pipe clamping assembly loosens both ends of the finished gas pipe and moves away from it. The main clamping seat assembly loosens the finished product and then removes the finished gas pipe.

[0016] The use of an auxiliary clamping device to clamp the two ends of the bent pipe not only ensures the accurate reservation of the pipe section to be processed, but also forms an inclined guide pipe section through the tapered reaming component, providing a good positioning basis for the subsequent installation of the connector and enhancing the sealing and reliability of the connection.

[0017] The insertion of the expansion piece allows the pipe section to form a bevel at a specific angle, which not only improves the matching accuracy between the pipe section and the connector, but also helps to achieve a tighter sealing effect, thereby improving the overall performance of the gas pipe.

[0018] Pre-installing the connector on the installation component can ensure the accurate position of the connector, provide convenience for subsequent press-in operations, and reduce errors during the installation process.

[0019] The two ends of the elbow are clamped by the auxiliary clamping device 2 on the assembly module, which ensures the tight connection between the connector and the elbow, and improves the sealing and structural stability of the gas pipe.

[0020] The clamping operation of the tube clamping assembly makes the inner walls of both ends of the bent pipe fit tightly with the connector. By precisely controlling the pressure and the movement of the clamping block, the sealing and connection strength of the gas pipe are achieved.

[0021] Preferably, in the above-mentioned gas pipe connector crimping and bundling sealing process, the connector is provided with a guiding bevel.

[0022] The design of the guide bevel improves the matching accuracy between the connector and the elbow, ensures stability and tightness during the press-in process, and thus enhances the sealing and durability of the connection.

[0023] Preferably, in the above-mentioned gas pipe connector buckling and bundling tube sealing process, the buckling tube assembly includes an oil cylinder assembly, a clamping block assembly, and a main clamping cylinder. The oil cylinder assembly includes an inclined surface limiter, a movable inner cylinder, an outer cylinder, and a sealing plug. The clamping block assembly consists of 8 clamping blocks, which are movably connected to the movable inner cylinder, and the movable inner cylinder is placed in the outer cylinder. An oil cavity is formed between the movable inner cylinder and the outer cylinder. The number of the sealing plugs is two and they are arranged in the oil cavity. The oil chamber is sealed at the front and rear ends, and the outer cylinder is provided with an oil filling hole, which is connected to the oil chamber. The clamping block is provided with a clamping inclined surface, which cooperates with the inclined surface limiting portion. In step S9, the main clamping cylinder injects pressurized oil into the oil chamber through the oil filling hole, and the mobile inner cylinder receives the thrust of the oil and moves outward and pushes the clamping block toward the inclined surface limiting portion. Under the limiting action of the inclined surface limiting portion, the clamping block shrinks inward and clamps the inclined guide pipe sections at both ends of the semi-finished gas pipe so that the inner walls of the two ends of the bent pipe are close to the connecting head.

[0024] The design of the cylinder assembly, clamping block assembly and main clamping cylinder of the pipe crimping assembly achieves uniform and effective clamping of the bent pipe. The power provided by the hydraulic system improves the efficiency and reliability of the crimping process.

[0025] The design of the inclined limiter, movable inner cylinder, outer cylinder and sealing plug in the cylinder assembly ensures the sealing and stability of the hydraulic system. At the same time, the design of the oil filling hole facilitates the injection of hydraulic oil and the connection of the oil chamber, improving the convenience of operation.

[0026] The clamping block assembly consists of 8 clamping blocks, and the design of its movably connected to the moving inner cylinder enables the clamping blocks to flexibly adapt to elbows of different diameters, thereby improving the versatility and adaptability of the process.

[0027] Preferably, in the above-mentioned gas pipe connector crimping bundle sealing process, the movable inner cylinder is provided with an oil push step, and in step S9, the oil push step cooperates with the pressure oil to provide a thrust for the lateral movement of the movable inner cylinder.

[0028] The design of the oil push step provides the necessary lateral thrust for moving the inner tube during the crimping process, ensuring that the clamping block can evenly shrink inward and tightly clamp the elbow, thereby improving the sealing performance of the gas pipe.

[0029] Preferably, in the above-mentioned gas pipe connector crimping and bundling sealing process, the length of the pipe section to be processed is in the range of 25-27 mm.

[0030] By limiting the length range of the pipe section to be processed to 25-27 mm, the consistency and repeatability of the hole expansion process are ensured, which helps to improve the standardization and mass production level of gas pipe production.

[0031] Preferably, in the above-mentioned gas pipe connector crimping and bundling sealing process, the pipe section to be processed in step S3 forms a 60° expanded inclined guide pipe section.

[0032] Preferably, in the above-mentioned gas pipe connector crimping and bundling sealing process, the length of the inclined guide pipe section is in the range of 3-4 mm.

[0033] The 60° expansion angle and 3-4mm length of the sloped guide pipe section provide the best matching angle and contact area for the connector and the elbow, enhancing the sealing and structural stability of the connection.

[0034] Preferably, in the above-mentioned gas pipe connector crimping and bundling sealing process, the main clamping seat assembly is provided with a main limiting groove, and the bent pipe sections at both ends of the bent pipe are placed in the main limiting groove.

[0035] The main limit groove design in the main clamping seat assembly ensures that the bent pipe sections at both ends of the bent pipe can be accurately placed, improving the accuracy and repeatability of the entire crimping tube sealing process. BRIEF DESCRIPTION OF THE DRAWINGS
