Description

Technical Field

[0001] The present invention relates to the technical field of metal hoses, and particularly to a manufacturing device and a usage method of a metal hose. Background Art

[0002] A metal hose is an important component in the connecting pipelines of modern industrial equipment. Generally, a metal hose consists of three major parts: a corrugated pipe, a wire mesh sleeve, and a joint. The corrugated pipe is the main body of the metal hose and plays a flexible role. The wire mesh sleeve plays a role in strengthening and shielding. The joint plays a connecting role. Metal hose products include oil suction and discharge hoses, steam hoses, sandblasting hoses, acid and alkali suction and discharge hoses, food hoses, oxygen blowing hoses, and various special-shaped hoses, etc. They are widely used in industries such as machinery, chemical industry, petroleum, metallurgy, and food.

[0003] In the process of manufacturing the corrugated pipe of a metal hose, it is generally made by bending a steel strip into shape, welding steel pipes, heat treatment, and corrugating. During the process of welding the steel strip into shape, it is necessary to cool the steel pipe and perform grinding and cleaning operations on the welding sites. Finally, it is also necessary to perform a sealing test on the welded steel pipe. The existing steel pipe forming and welding equipment has a single function and is not convenient for grinding, cleaning, and testing operations during the forming and welding process. Therefore, a manufacturing device and a usage method of a metal hose are proposed. Summary of the Invention

[0004] To solve the technical problem that the existing steel pipe forming and welding equipment has a single function and is not convenient for grinding, cleaning, and testing operations during the forming and welding process, the present invention provides a manufacturing device and a usage method of a metal hose.

[0005] The present invention is implemented by the following technical solutions: A manufacturing device of a metal hose includes a steel pipe forming device for making a steel strip into a steel pipe.

[0006] The steel pipe forming device includes a base plate, a steel strip extrusion forming assembly, a shaping and welding mechanism, and a cleaning mechanism that are fixedly connected to the top of the base plate and are distributed in sequence. A shaping, cleaning, and testing assembly is fixedly connected to the shaping and welding mechanism.

[0007] The shaping, cleaning and detecting assembly includes a bracket with an L-shaped structure fixedly connected to the shaping and welding mechanism. A rotating mechanism is connected to the bottom of the bracket, and a holding rod fixedly connected to the bracket is arranged on one side of the rotating mechanism. A front-end spraying mechanism, an inner-ring cleaning mechanism, a rear-end withdrawing mechanism and two groups of isolation discs are sequentially arranged on the outer ring of the rotating mechanism. The rotating mechanism includes a support tube fixedly connected to the bracket, a partition plate with a Y-shaped structure fixedly connected inside the support tube, and a rotating tube rotatably sleeved on the outer ring of the support tube. The partition plate divides the inner ring of the support tube into a liquid inlet chamber 1, a liquid pumping chamber and a liquid inlet chamber 2 which are sequentially distributed. The support tube is penetrated with a communication hole 1, a communication hole 2 and a communication hole 3, and the rotating tube is penetrated with an arc-shaped communication groove 1, a communication groove 2 and a communication groove 3. The communication hole 1 is communicated with the front-end spraying mechanism, the liquid inlet chamber 1 and the communication groove 1, the communication hole 2 is communicated with the rear-end withdrawing mechanism, the liquid pumping chamber and the communication groove 2, and the communication hole 3 is located between the two groups of isolation discs and is communicated with the liquid inlet chamber 2 and the communication groove 3. The bracket is connected with a driving mechanism for driving the rotating tube to rotate.

[0008] Through the above technical solution, the cut steel strip is passed through a plurality of steel strip extrusion forming assemblies arranged on the top of the substrate, and the strip-shaped steel strip is successively extruded into a tubular structure. At the same time, the shaping, cleaning and detecting assembly extends into the inner part of the steel pipe blank with an arc-shaped structure formed by the bending of the steel strip at the position where the steel strip has not been completely formed into a tubular structure. The shaping, cleaning and detecting assembly first abuts and shapes against the shaping and welding mechanism on the inner circle of the steel pipe, and then cools the steel pipe after the shaping and welding mechanism completes the welding of the steel pipe. While cooling, the weld on the inner circle of the steel pipe is polished and removed, and at the same time, the cleaning mechanism cleans the welding seam 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 discs, and the welding effect of the steel pipe is judged by the state of whether the high-pressure medium overflows.

The cooling liquid can also wash the waste chips ground by the grinding blocks. The washed liquid enters the second communication groove along the liquid extraction hole, and then is transported to the liquid extraction pipe through the second communication hole and the liquid extraction cavity and discharged.

[0012] As a further improvement of the above solution, the inner ring cleaning mechanism includes two outer side plates fixedly sleeved on the outer ring of the rotating pipe.

Between adjacent grinding blocks, there are fan blades fixedly connected to the outer ring of the driven plate.

The mounting plate is rotatably sleeved with a ring-shaped shaping plate. A welding machine is installed at the top of one side of the mounting plate.

[0016] As a further improvement of the above solution, the cleaning mechanism includes a vertical plate fixedly connected to the substrate. The vertical plate is rotatably sleeved with a ring-shaped stabilizing plate. A scraper mounting plate is installed at the top of one side of the vertical plate, and a scraper is installed at the bottom of the scraper mounting plate.

[0062] Embodiment 2

[0063] In this embodiment, a usage method of a manufacturing device for a metal hose is proposed, including the following steps:

[0064] Step S1: The cut steel strip is extruded into a steel pipe blank in a tubular structure by the steel strip extrusion forming assembly 3;

[0065] Step S2: The steel pipe blank is extruded and shaped from the inner and outer circles by the shaping, cleaning and detecting assembly 5 and the shaping and welding mechanism 4. After extrusion and shaping, welding is performed by the shaping and welding mechanism 4;

[0066] Step S3: The inner circle of the welded steel pipe blank is cleaned by the shaping, cleaning and detecting assembly 5, and a high-pressure medium for detecting the welding effect is injected;

[0067] Step S4: The weld seam on the outer side of the steel pipe blank is first cleaned by the cleaning mechanism 6, and the welding effect of the weld seam is detected after cleaning.

[0068] The more specific operation steps are as follows:

[0069] 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.

[0070] 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;

[0071] 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;

[0072] 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.

[0073] 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.
