Description

technical field [0001] The invention relates to concrete pipeline processing equipment, in particular to an improvement to an air supply device of a radial extrusion pipe making machine, a radial extruder comprising the improved air supply device and a working method. Background technique [0002] In the 1970s and 1980s, the vertical pipe manufacturing technology of the American McCracken Company, Haijue Rotaire and other companies came out. This technology can greatly improve the processing and manufacturing efficiency of concrete pipes. In the mid-1980s, relevant domestic enterprises introduced this technology to manufacture concrete pipes, but they have not been able to grasp the core technology. As a result, the technology has been stagnant until 2010. Most similar pipes are processed and produced by mandrel vibration technology. Mandrel vibration technology can process pipes that meet market requirements, but the production cycle is long and the processing efficiency i...

Problems solved by technology

In actual application, due to the harsh production environment, a lot of dust, and large vibrations, the positioning of the fixed stopper requires high precision. Once a small amount of radial deviation occurs, it is easy to cause misalignment of the butt joint, and the seal of the butt joint valve is easy to fail, resulting in When the whole machine is working, the fixed cage cylinder on the mold is insensitive and inaccurate

The most perplexing technical problem in this field is that due to the axial butt joint air supply, the cylinder (33) needs to maintain an air pressure greater than the air pressure of the work advance / work retreat no matter it is in the work-in state or the work-retreat state, otherwise the work at the butt joint will The reaction force caused by the forward / backward air pressure will lead to air leakage at the butt joint, which will result in extremely high energy consumption of the cylinder (33), and it is necessary to maintain a high-pressure clamping state throughout the process

[0005] In addition, although the air supply device is only a basic part of the whole machine during the processing, once its action sensitivity (accuracy of action time, speed of driving the plate movement, etc.) is reduced, it will cause the concrete pipe 77 (like Figure 18 ) on the outer wall of the insert plate "scar", light is the product quality problem, serious will cause the overall pipe strength to drop; second, it will lead to inaccurate positioning of the reinforcement cage 76 inside the concrete pipe 77 (not in the design of the pipe thickness direction location), resulting in reduced strength of the concrete pipe 77
