Problems solved by technology

[0002] Existing gas crackers (crackers) are hereinafter referred to as expanders, such as: CN201611099345.2, CN201520283079.3, CN201510489513.8, CN201510556527.7 The connection part usually adopts the thread method (the thread needs to be machined) or welding method or butt welding No matter which method is used for manufacturing, there will be weak points in the connection between the inflation head, the energy dissipation head and the expansion tube, which will cause the connection part to crack first when the expander expands, and the flying head will appear.
[0003] The existing expander (cracker) still has many components, and the technical problems of complex processing and assembly processes for each component
[0004] For example, the patent document with the notification number CN205858345U discloses "plug, expansion tube, activator, liquid filling hole and lock valve, the plug is provided with an activator installation port, and the plug or expansion tube is provided with a liquid filling hole." ", although it saves a lot of parts and assembly steps compared with other expanders, there are still two processings at both ends of the expansion tube, that is, one end needs to be welded during assembly, and the other end needs to be threaded and sealed, or both ends are connected by welding. The welding master's technical level is extremely high. Less than 20% of the joints are welded with a constant thickness and no gaps. Thread processing, the two ends of

Abstract

The invention discloses a supercritical oxygen fracturing device which comprises an expansion pipe and a gas-inflated ignition head. A necking port in one end of the expansion pipe is sealed, and a necking port in the other end of the expansion pipe is provided with the gas-inflated ignition head. A necking port machining method comprises the steps that the expansion pipe is fixed through a clamp, the clamp is used for rotating the expansion pipe and heating one end of the expansion pipe, the end of the expansion pipe is heated till being approximate to or reaching plastic deformation, the front portion of a necking mold makes contact with the end of the expansion pipe, the end of the expansion pipe moves from the front portion to the tail of the necking mold, the necking mold carries out extrusion thickening molding on the end of the expansion pipe, a through hole knife is used for forming a through hole in the end of the expansion pipe and fixing the hole diameter, the steps are repeated to carry out extrusion thickening molding on the other end of the expansion pipe, a through hole is formed, and the hole diameter is fixed, or sealing thickening molding is carried out. A pressure container is prepared from the expansion pipe through the necking port machining method. The supercritical oxygen fracturing device has the advantages that the structure is simple, the structural components are easy to machine, the manufacturing cost is low, head flying and gas leakage are avoided, conveying is safe, no dud hidden danger exists, and expansion force is large.
