[0031] Example 2

[0032] This embodiment provides a method for using a metal hose manufacturing device, including the following steps: Step S1: using the steel strip extrusion molding assembly 3 to extrude the cut steel strip into a steel pipe rough material with a tubular structure; Step S2: using the shaping cleaning detection component 5 and the shaping welding mechanism 4 to perform extrusion shaping from the inner and outer rings of the steel pipe rough material, and after extrusion shaping, using the shaping welding mechanism 4 to perform welding; Step S3: using the shaping cleaning detection component 5 to clean the inner ring of the welded steel pipe rough material, and injecting a high-pressure medium for detecting the welding effect; Step S4: Use the cleaning mechanism 6 to first clean the weld on the outside of the steel pipe rough material, and then detect the welding effect of the weld after cleaning.

[0033] More specific steps are as follows: When processing the metal bellows in the metal hose, first, the cut steel strip is passed along multiple groups of steel strip extrusion molding components 3 arranged on the top of the substrate 2, and the steel strip with a long strip structure is successively extruded into a tubular structure. At the same time, the shaping, cleaning and detection component 5 is inserted into the steel pipe blank with an arc structure formed by the bending of the steel strip at the position where the steel strip has not completely formed a tubular structure. The shaping, cleaning and detection component 5 is first used to contact and shape the inner ring of the steel pipe with the shaping welding mechanism 4, and then the steel pipe is cooled after the shaping welding mechanism 4 completes the welding of the steel pipe. While cooling, the weld of the inner ring of the steel pipe is polished and cleaned. At the same time, the cleaning mechanism 6 cleans the welding weld from the outside of the steel pipe. Finally, a high-pressure medium for detecting the welding seal of the steel pipe is injected between the two groups of isolation disks 24, and an image acquisition device such as a camera installed on the cleaning mechanism 6 is used to collect whether the high-pressure medium on the outside of the steel pipe overflows to judge the welding effect of the steel pipe. When cooling the steel pipe and cleaning the inner ring, the motor 2 of the driving mechanism is started, so that the chain drives the sprocket 2 to rotate, and then the rotating tube 86 rotates. At this time, the rotating tube 86 drives the gear ring 1 227 to rotate, and then the gear 226 and the gear ring 228 rotate, so that the driven plate 223 rotates, and the grinding block 224 on the driven plate 223 grinds the raised burrs at the welding part of the inner ring of the steel pipe. At this time, the cooling medium input by the liquid inlet pipe 1 enters the position of the liquid inlet chamber 1 83, and then along the connecting hole The first 87 and the connecting groove 810 enter the transfer groove 1 of the spray plate 211, and then the inner wall of the welded steel pipe is sprayed upward from the spray hole 212 to cool down the inner wall. The cooling liquid can also wash the waste chips polished by the grinding block 224. The flushed liquid enters the connecting groove 2 811 along the liquid extraction hole 232, and then is transported to the liquid extraction pipe along the connecting hole 2 88 and the liquid extraction cavity 84 for discharge. At the same time, the scraper on the cleaning mechanism 6 scrapes off the welding convex points and burrs on the outer wall of the steel pipe; When testing the welding quality, the high-pressure medium is delivered between the two sets of isolation plates 24 in the above manner. When the high-pressure medium overflows from the steel pipe, it indicates that the welding is unqualified. At the same time, in order to ensure the escape of the cooling medium and the high-pressure medium, sealing rings for sealing are provided on the outer rings of the isolation plate 24, the spray plate 211 and the liquid extraction plate 231; Before welding, the spray plate 211 contacts the steel pipe from the inner ring, and the shaping plate 42 on the shaping welding mechanism 4 shapes the steel pipe from the outer ring to ensure that the steel pipe is accurately shaped before welding. When the inner and outer rings of the steel pipe are cleaned, the stabilizing plate and isolation plate 24 are used to shape and contact the inner ring of the steel pipe in the above-mentioned manner.

[0034] When processing the metal hose, this design performs resistance shaping on the steel pipe from the inner and outer circles, effectively preventing deformation during welding and improving the consistency of the metal hose. After welding, rapid cooling and cleaning operations are performed to remove the protrusions and burrs generated by welding. No additional processing is required later, which improves the processing efficiency of the metal hose. After welding is completed, welding inspection is carried out in time to quickly detect the welding effect.
