Description of the invention (1) The present invention is a method for forming a stainless steel bottle for a fire extinguisher, especially a new designer who can make a stainless steel bottle body quickly and improve the structural strength. According to the current manufacturing method of a steel bottle for a fire extinguisher As shown in Figure 11, 'mostly, an inner hollow pipe body (A) is welded to the bottom pipe end with a bottom cover (B), and a raised top cover (C) is welded to the edge of the top pipe. The convex portion of the top cover (c) is provided with a through hole (C1) in the axial direction, and the hole edge of the through hole (C1) is suitable for welding a thick wall (D) 'and the convex wall ( D) The outer periphery (or inner edge) is formed with a thread, which is suitable for the connection device (E):-Generally speaking, the cylinder of the fire extinguisher is a dry powder or liquid that can indeed bear high pressure, so the production quality requirements of the cylinder are very strict. It is not difficult to find out that there are still some manufacturing defects in this traditional method of making steel bottles without money. The main reasons are summarized as follows: This traditional molding method adopts welding as the primary reason for forming the stainless steel bottle. "Technical details" This structure is mainly welded bumps, top and bottom caps to the pipe ^ "In terms of the overall structure, there are three weld beads, which are not only more complicated and slow to manufacture, but also the longer the total length of the weld beads, the more they can be destroyed by the surname of the weld beads." The unevenness leads to the unevenness of the ability to withstand high pressure, so it is easy to rupture from the weak part of the weld bead structure, causing the contents of the cylinder to seep there. Therefore, this traditional structure is not conducive to the long-term containment of high-pressure content. Thing. In view of the fact that the conventional method for forming a conventional steel bottle still has manufacturing defects, the inventor immediately thought about researching and improving the method ', and after many tests, the invention finally came into being.

Good effect. The main purpose is to make the pipe body penetrate between the fixed seat, and the pipe body is sleeved with a bearing in the fixed seat. The two ends of the f body are suitable for being pushed up by the two force-applying ends, which can not only push axially against the pipe body and shrink inwardly. It can also be linked with the rotation of the pipe body at the same time. The first forming mold is set at the center of the pipe body. It moves radially toward the pipe body by an appropriate distance to force it to resist. The pipe body rotation can cause the pipe body to be formed according to the mold shape. In the tapered section, due to the abutment of the two application ends at Xiao Shi, the tapered section of the pipe body will also form a thicker wall. The cutting knife will be cut off from the center of the tapered section to form two unilateral openings and the other end fixture. The bottle blank of the tapered bottle mouth can be directly threaded at the bottle mouth and the bottom cap can be welded at the open end.

Description of the invention (5) Connected to the bottom cover (52), so it can significantly reduce the fresh road 'and thereby increase the structural strength ° In addition, the present invention can also increase a molding process' as shown in the seventh figure, The bottle body blank (5) is clamped again by the fixing seat (11) on the periphery of the two ends. 'The open end of the bottle body blank (5) is abutted against the end face of a fixed body (7)' and the bottle mouth (51 ) Is against the end face of the force applying end U2) and the two ends of the bottle blank (5) are driven by the force applying end (12) and the fixed body (7) to rotate together, while the bottle blank (5) is rotating, It can be axially biased by the unilateral force applying end (12) relative to the bottle blank (5), so that the open end of the bottle blank (5) can be abutted against the end face of the fixed body (7) due to unilateral force, As a result, the thickness of the tube at the open end is significantly thickened due to squeezing by external force. In addition, the fixed body (7) can be rotated at high speed with the bottle blank (5), so that the forming mold (2) is opposed The bottle blank (5) is extruded. Since the molding die (2) has only one side of the arc surface, the original open end of the bottle blank (5) can form another tapered bottle mouth. (53); Or 'see the eighth figure, the bottle mouth (51) at the top of the bottle blank (5) and the bottle mouth (5 3) at the bottom are formable threads (both internal and external threads can be), and the top The bottle mouth (51) can be connected with the joint device (6), and the bottom bottle mouth (53) can make an externally threaded fixing piece (8) threaded washer (81) fixed to the bottle mouth (53) 'Form a seal, with the same effect as the above-mentioned welded bottom cap (52); In addition, the bottle mouth (53) can also be connected with a pressure relief valve (this is a conventional structure' not shown), the The pressure relief valve can be used to release the internal pressure of the bottle blank (5) when the pressure inside the bottle blank (5) rises due to a change in temperature difference, and ensure the safety of the bottle blank (5). The method of forming the mouth of the bottle can also be used as the ninth and tenth circles. It mainly uses several sets of forming molds (2) along the center of the pipe body (1)
