Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher processing, in particular to a ring weld scar flattening machine for a fire extinguisher bottle body. Background Technique

[0002] A fire extinguisher is a portable fire-fighting tool. Chemical substances are placed inside the fire extinguisher to extinguish fires. Fire extinguishers are one of the common fire-fighting equipment and are stored in public places or places where fires may occur. The components filled in different types of fire extinguishers are different and are designed specifically for different fire causes. Care must be taken during use to avoid adverse effects and dangers.

[0003] The bottle body of a fire extinguisher belongs to a pressure vessel. In general production processes, iron sheets are rolled and welded into pipes, and then the top and bottom of the bottle body are welded. Since there will be weld scars after welding, the weld scars will affect the aesthetics and use comfort of the bottle body. Therefore, a ring weld scar flattening machine for a fire extinguisher bottle body is needed.

[0004] The existing patent (publication number: CN207479237U) discloses an adjustable ring weld scar flattening machine for a fire extinguisher bottle body. One end of the bed body is provided with a main spindle box. A tightening rod extends out of the end face of the main spindle box facing the other end of the bed body. A tightening block is provided on the side wall of the end of the tightening rod. The tightening rod is fixedly connected to the main spindle inside the main spindle box. The main spindle is driven by a motor and is rotatably connected to the main spindle box; the other end of the bed body relative to the main spindle box is provided with a flattening device.
