Description

Technical Field

[0001] This invention relates to the field of forging manufacturing technology, specifically to a corrosion-resistant forging manufacturing equipment and its preparation process. Background Technology

[0002] Forging is a processing technique where metal is subjected to pressure and plastically deformed into a desired shape or subjected to appropriate compressive force, typically achieved by hammering. Corrosion-resistant forgings are workpieces made from corrosion-resistant alloy materials, possessing excellent corrosion resistance and stability under high temperature and pressure, and are widely used in various fields such as chemical, energy, aerospace, and water conservancy.

[0003] A bellows compensator is a type of compensating element that primarily utilizes the effective expansion and contraction of the bellows to absorb dimensional changes in pipelines or containers caused by thermal expansion and contraction. It can also be used for noise reduction and vibration damping. During manufacturing, bellows compensators are typically forged or pressed from steel plates heated to a certain temperature in a mold. After manufacturing, their surfaces need to be polished to eliminate roughness and scratches.

[0004] Since its outer surface is exposed, it can be polished manually or by machine. However, in actual production, when polishing its inner surface, it was found that due to the presence of corrugations, polishing debris tends to accumulate at the corrugations. When the polishing head polishes this area, these accumulated polishing debris not only adhere to the surface of the polishing head and are difficult to clean, reducing the subsequent polishing accuracy, but also scratch the inner wall of the corrugated compensator, reducing its quality. At the same time, due to the centrifugal force, the polishing debris attached to the surface of the polishing head will also splash onto the already polished area, requiring further cleaning work. This not only increases economic costs but also directly extends the manufacturing cycle of the corrugated compensator. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a corrosion-resistant forging manufacturing equipment and its preparation process. By performing two polishing processes—coarse grinding and fine grinding—on the clamped and fixed corrugated compensator, combined with air blowing, the invention solves the problem of polishing shavings adhering to the grinding head during the polishing process, which is difficult to clean and leads to a decline in polishing quality. It also solves the problem of polishing shavings easily splashing and adhering to the inner wall of the polished corrugated compensator, which leads to extended processes and increased costs.

[0015] The present invention also provides a preparation process using the above-mentioned corrosion-resistant forging manufacturing equipment, comprising the following steps:

[0016] S1. Loading and clamping: The corrugated compensator is placed vertically on the arc support plate by hand. By turning the handle, the rectangular blocks on the left and right sides will drive the arc clamping blocks to move towards each other under the action of the first threaded rod, thereby clamping and fixing the corrugated compensator.

[0019] S4. Material unloading: After S3 is completed, the rotating mechanism stops running. Manually rotate the handle in the opposite direction to release the corrugated compensator from its clamping state. The material can then be unloaded manually.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention uses a two-stage polishing process, first coarse grinding and then fine grinding, to polish the inner wall of the corrugated compensator. It also cleans the surface. Compared with traditional polishing processes, this is more efficient and achieves better polishing results, thus ensuring the production quality of the corrugated compensator.

[0022] 2. The air blowing mechanism of this invention can continuously blow air into the gap between the inner wall of the corrugated compensator and the polishing device during the polishing process. At the same time, the air jet angle of the air nozzle can be changed by adjusting the air outlet pipe, so that the airflow can remove chips better. This will blow off the polishing chips generated during the polishing process in time and take away the polishing debris adhering to the first and second arc polishing sections, thereby improving the polishing accuracy. In addition, it can also prevent polishing chips from adhering to the inner wall of the corrugated compensator after polishing. Attached Figure Description

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] Example 1:

[0043] See Figures 1 to 3 as well as Figure 6 A corrosion-resistant forging manufacturing equipment includes a workbench 1. A clamping device 2 is rotatably mounted on the middle of the upper surface of the workbench 1. A rotating mechanism 21 is mounted on the middle of the lower surface of the workbench 1. The upper end of the rotating mechanism 21 extends above the workbench 1 and is fixedly mounted on a rotating disk 22. An annular slide is provided on the workbench 1 below the rotating disk 22. Balance sliders 23 are evenly arranged along the circumference of the annular slide. The upper end of the balance sliders 23 is fixedly connected to the lower surface of the rotating disk 22. A clamping mechanism 24 is provided on the upper surface of the rotating disk 22.

[0044] An L-shaped frame 211 is fixedly installed on the right side of the lower end face of the workbench 1. A rotary motor 212 is fixedly installed on the L-shaped frame 211 via a motor base. An output gear 213 is installed on the output shaft of the rotary motor 212 via a key connection. A reduction gear 214 meshes with the left side of the output gear 213. The reduction gear 214 is fixedly installed at the lower end of the gear shaft 215. The gear shaft 215 is rotatably installed in the middle of the workbench 1, and the upper end of the gear shaft 215 extends to the top of the workbench 1 and is fixedly connected to a rotating disk 22.

[0045] A rectangular groove is laterally formed in the middle of the upper surface of the rotating disk 22. Liners 241 are symmetrically installed at both ends of the rectangular groove. A first threaded rod 243 is rotatably installed between the liners 241. The threaded sections on the first threaded rod 243 are symmetrically formed. The right end of the first threaded rod 243 extends through to the right side of the liner 241 and is fixedly installed with a baffle 244. A handle 245 is fixedly connected to the middle of the right side wall of the baffle 244 near the upper end. A strip-shaped slider 242 is slidably disposed within the rectangular groove. A rectangular block 246 is fixedly connected to the upper end of the slider 242. The rectangular block 246 is symmetrically spirally connected to the first threaded rod 243. An L-shaped plate 247 is fixedly connected to the upper end of the rectangular block 246. An arc-shaped clamping block 248 is fixedly connected to the near end of the L-shaped plate 247. Rubber protrusions are evenly arranged on the arc-shaped concave surface of the arc-shaped clamping block 248. A fixing rod 249 is fixedly installed near the lower end of the L-shaped plate 247. An arc-shaped support plate 2410 is fixedly connected to the end of the fixing rod 249 away from the L-shaped plate 247.

[0046] In practice, the corrugated compensator is manually placed on the arc-shaped support plate 2410. By turning the handle 245, the rectangular blocks 246 on the left and right sides will drive the L-shaped plate 247 and the arc-shaped clamping block 248 to move towards each other under the action of the first threaded rod 243. Thus, the corrugated compensator is clamped and fixed by the arc-shaped clamping block 248. Then, the rotary motor 212 is started, which drives the output gear 213 to rotate. Under the action of the reduction gear 214, the gear shaft 215 and the rotating disk 22 will also rotate, thereby achieving the purpose of driving the corrugated compensator to rotate after it is clamped and fixed.

[0047] Example 2:

[0048] The technical solution is basically the same as that in Embodiment 1, see below. Figures 1 to 6 The difference lies in that a polishing device 3 is provided above the clamping device 2, and the lower end of the polishing device 3 is fixedly connected to the worktable 1. A drive motor 31 is fixedly installed in the middle of the upper surface of the polishing device 3 via a motor base. An air blowing mechanism 32 is fixedly installed at the lower end of the drive motor 31. A polishing shaft 33 is fixedly installed at the lower end of the air blowing mechanism 32. The polishing frame 34 is fixedly installed in the middle of the polishing shaft 33 and has a hollow structure. An arc-shaped polishing section 35 is uniformly fixedly arranged on the outer wall of the polishing frame 34 along its circumference.

[0049] The polishing device 3 further includes a support mechanism 36, an adjustment mechanism 37, and a cleaning mechanism 38. The support mechanism 36 is fixedly installed on the upper surface of the worktable 1, and the adjustment mechanism 37 is slidably arranged on the polishing frame 34. The upper and lower ends of the adjustment mechanism 37 are fixedly installed on the polishing shaft 33, and the lower end of the polishing shaft 33 is fixedly connected to the cleaning mechanism 38.

[0050] The lower end of the drive motor 31 is connected to a second threaded rod 321 via a coupling. A lifting plate 322 is screwed onto the second threaded rod 321. Limiting plates 323 are symmetrically installed on the left and right sides of the lifting plate 322. Limiting grooves are symmetrically opened on the left and right inner side walls of the U-shaped plate 362. The end of the limiting plate 323 away from the lifting plate 322 is set in the limiting groove. A horizontal plate 324 is fixedly installed at the lower end of the limiting groove. An air cylinder 325 is installed on the upper surface of the horizontal plate 324. A piston 326 is slidably installed inside the air cylinder 325. A pressure rod 327 is fixedly connected to the upper end of the piston 326. The upper end of the pressure rod 327 is fixedly installed on the lower surface of the limiting plate 323. An air outlet is provided at the lower end of the opposite side wall of the air cylinder 325. An air outlet pipe 328 is connected to the air outlet. The lower end of the air outlet pipe 328 extends to the lower part of the horizontal plate 324 and is equipped with an air nozzle 329.

[0051] A lifting cylinder 361 is fixedly installed on the upper surface of the workbench 1 near the left and right sides via a cylinder base. A U-shaped plate 362 is fixedly connected to the upper end of the lifting cylinder 361. The opening of the U-shaped plate 362 faces downward. A connecting plate 364 is fixedly installed on the front and rear side walls of the U-shaped plate 362 near the middle. A guide rod 363 is provided through the connecting plate 364. The lower end of the guide rod 363 is fixedly connected to the workbench 1.

[0052] The polishing frame 34 has symmetrically mounted mounting discs 371 on the polishing shafts 33 on both the upper and lower sides. Electric push rods 372 are evenly mounted on the opposite sidewalls of the mounting discs 371 along their circumference. The extended end of the electric push rod 372 is hinged to a connecting rod 373. The end of the connecting rod 373 away from the electric push rod 372 is hinged to a push seat 374. A second arc-shaped polishing section 377 is fixedly mounted on the outer sidewall of the push seat 374. The polishing frame 34 has rectangular through slots with outward openings evenly opened along its circumference. Wheel slots are opened on the sidewalls of the rectangular through slots. The push seat 374 is slidably mounted in the wheel slots through pulleys 376. The push seat 374 and the pulleys 376 are fixedly connected. A compression spring 375 is installed between the push seat 374 and the rectangular through slot.

[0053] The lower end of the polishing shaft 33 is fixedly connected to a rotating column 381. Reinforcing rods 382 are evenly installed on the outer wall of the rotating column 381 along its circumference. A cleaning ring frame 383 is provided at the end of the reinforcing rod 382 away from the rotating column 381. A cleaning airbag 384 is sleeved on the outer side of the cleaning ring frame 383. Electromagnetic control nozzles 386 are evenly arranged on the upper surface of the cleaning ring frame 383 along its circumference. The lower end of the electromagnetic control nozzle 386 is connected to the inside of the cleaning airbag 384. A solenoid valve 385 is installed in the middle of the electromagnetic control nozzle 386.

[0054] In this embodiment, a one-way air inlet is provided at the bottom of the air cylinder 325 to facilitate timely replenishment of gas inside the air cylinder 325. The cleaning airbag 384 is initially filled and has a wear-resistant layer on its outer wall. An air inlet valve is installed on the lower end face of the cleaning airbag 384 near the left side. Before the cleaning airbag 384 is put into operation, it can be manually inflated.

[0055] In addition, it should be noted that the air outlet pipe 328 is a rubber hose, the purpose of which is to allow the orientation of the air nozzle 329 to be adjusted as needed during actual use, thereby improving its chip removal effect.

[0056] In actual operation, after the corrugated compensator is clamped and fixed, the drive motor 31 is started. The drive motor 31 drives the second threaded rod 321, polishing shaft 33, polishing frame 34, first arc-shaped polishing section 35 and cleaning mechanism 38 to rotate. At the same time, the lifting cylinder 361 is started, which drives the C-shaped plate 362 to move downward. During this process, the guide rod 363 and the connecting plate 364 can cooperate with each other to ensure the stability of the downward movement of the C-shaped plate 362, thereby driving the aforementioned drive motor 31, second threaded rod 321, polishing shaft 33, polishing frame 34, first arc-shaped polishing section 35 and cleaning mechanism 38 to move downward.

[0057] When the outer wall of the cleaning airbag 384 contacts the inner wall of the corrugated compensator, the cleaning airbag 384 can clean the inner wall of the corrugated compensator, thereby removing the surface dirt adhering to the inner wall. When the first arc-shaped polishing section 35 contacts the inner wall of the corrugated compensator, the first arc-shaped polishing section 35 can perform coarse grinding on the inner wall, which can not only further remove the dirt on the inner wall of the corrugated compensator, but also remove the oxide layer on the inner wall, ensuring the subsequent polishing effect. After the coarse grinding process is completed, the cleaning airbag 384 and the first arc-shaped polishing section 35 will reset, and the drive motor 31 will continue to run.

[0058] The electric push rod 372 is activated, which pushes the connecting rod 373, thereby causing the push seat 374 to spread outwards. At this time, the lifting cylinder 361 is activated again, which drives the shaped plate 362 to move downwards again. During this process, the second arc-shaped polishing section 377 can perform secondary polishing on the inner wall of the corrugated compensator. At the same time, the solenoid valve 385 can control the electromagnetic control nozzle 386 to open. At this time, the air inside the cleaning airbag 384 can be blown down the second arc-shaped polishing section 377 through the electromagnetic control nozzle 386, thereby blowing off the polishing debris generated during the secondary polishing process.

[0059] During the rotation of the second threaded rod 321, due to the action of the limiting plate 323, the lifting plate 322 and the limiting plate 323 will move downward synchronously. At this time, the limiting plate 323 can drive the pressure rod 327 to move downward. Under the action of the piston 326, the air inside the air cylinder 325 will be squeezed into the air nozzle 329 through the air outlet pipe 328, and then sprayed towards the inside of the corrugated compensator through the air nozzle 329. In this way, a downward airflow can be formed between the first arc-shaped polishing section 35 and the inner wall of the corrugated compensator, and between the second arc-shaped polishing section 377 and the inner wall of the corrugated compensator. This can not only blow off the polishing debris generated during the polishing process in time, but also take away the polishing debris adhering to the first arc-shaped polishing section 35 and the second arc-shaped polishing section 377, improve the polishing accuracy, and at the same time prevent the polishing debris from adhering to the inner wall of the corrugated compensator that has been polished.

[0060] Furthermore, the present invention also provides a preparation process utilizing the above-mentioned equipment for manufacturing corrosion-resistant forgings, comprising the following steps:

[0061] S1. Loading and clamping: The corrugated compensator is placed on the arc-shaped support plate 2410 by hand. The handle 245 is turned. Under the action of the first threaded rod 243, the rectangular blocks 246 on the left and right sides will drive the L-shaped plate 247 and the arc-shaped clamping block 248 to move towards each other. The corrugated compensator is clamped and fixed by the arc-shaped clamping block 248. Then, the rotary motor 212 is started. The rotary motor 212 drives the output gear 213 to rotate. Under the action of the reduction gear 214, the gear shaft 215 and the rotating disk 22 will also rotate, thereby achieving the purpose of driving the corrugated compensator to rotate after clamping and fixing.

[0062] S2, First Polishing: After S1 is completed, the drive motor 31 is started, which drives the second threaded rod 321, polishing shaft 33, polishing frame 34, first arc-shaped polishing section 35, and cleaning mechanism 38 to rotate. At the same time, the lifting cylinder 361 is activated, which drives the C-shaped plate 362 to move downward. During this process, the guide rod 363 and the connecting plate 364 cooperate with each other to ensure the stability of the downward movement of the C-shaped plate 362, thereby driving the aforementioned drive motor 31, second threaded rod 321, polishing shaft 33, polishing frame 34, first arc-shaped polishing section 35, and cleaning mechanism. 38 moves downwards. When the outer wall of the cleaning airbag 384 contacts the inner wall of the corrugated compensator, the cleaning airbag 384 can clean the inner wall of the corrugated compensator, thereby removing the surface dirt adhering to the inner wall. When the first arc-shaped polishing section 35 contacts the inner wall of the corrugated compensator, the first arc-shaped polishing section 35 can perform coarse grinding on the inner wall, which can not only further remove the dirt on the inner wall of the corrugated compensator, but also remove the oxide layer on the inner wall, ensuring the subsequent polishing effect. After the coarse grinding process is completed, the cleaning airbag 384 and the first arc-shaped polishing section 35 will reset, and the drive motor 31 will continue to run.

[0063] S3. Secondary polishing: Start the electric push rod 372, which pushes the connecting rod 373, thereby causing the push seat 374 to spread outwards. At this time, start the lifting cylinder 361 again, which drives the shaped plate 362 to move downwards again. During this process, the second arc-shaped polishing section 377 can perform secondary polishing on the inner wall of the corrugated compensator. At the same time, the solenoid valve 385 can control the solenoid control nozzle 386 to open. At this time, the air inside the cleaning airbag 384 can be blown down the second arc-shaped polishing section 377 through the solenoid control nozzle 386, thereby blowing off the polishing debris generated during the secondary polishing process.

[0064] S4. Material Discharge Processing: During the rotation of the second threaded rod 321, due to the action of the limiting plate 323, the lifting plate 322 and the limiting plate 323 will move downward synchronously. At this time, the limiting plate 323 can drive the pressure rod 327 to move downward. Under the action of the piston 326, the air inside the air cylinder 325 will be squeezed into the air nozzle 329 through the air outlet pipe 328, and then sprayed towards the inside of the bellows compensator through the air nozzle 329. In this way, the material can be discharged between the first arc-shaped polishing section 35 and the inner wall of the bellows compensator, as well as the second arc-shaped polishing section. A downward airflow is formed between 377 and the inner wall of the corrugated compensator, which can not only blow off the polishing debris generated during the polishing process in time, but also remove the polishing debris adhering to the first arc polishing section 35 and the second arc polishing section 377, thereby improving the polishing accuracy. At the same time, it can also prevent polishing debris from adhering to the inner wall of the already polished corrugated compensator. After the above S3 is completed, the rotating mechanism 21 stops running. By manually rotating the handle 245 in the opposite direction, the corrugated compensator is released from the clamping and fixed state, and the material can be unloaded manually.

[0065] One point to note is that in the above manufacturing process, the rotation direction of the corrugated compensator is opposite to the rotation direction of the polishing shaft 33, in order to improve the polishing efficiency.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
