Description

Technical Field

[0001] This utility model relates to the technical field of flange processing equipment, specifically to a stainless steel flange upsetting device. Background Technology

[0002] In the production and processing of stainless steel flanges, upsetting is a crucial step in shaping the flange blank, relying heavily on the precise pressure and shaping of the raw material by the stainless steel flange upsetting device. Currently available stainless steel flange upsetting devices suffer from numerous problems in structural design and practical application, severely impacting production efficiency and product quality stability. The connection structure between the upsetting head and the drive shaft of traditional upsetting devices is complex, often employing welding or multiple sets of bolts for interlocking. While welding ensures connection strength, disassembly becomes extremely difficult when the upsetting head wears out or needs to be replaced with a different specification, requiring complete disassembly of the entire device. This is not only time-consuming and labor-intensive but may also cause irreversible damage to the drive shaft. On the other hand, multiple bolt connections suffer from low installation and positioning accuracy, and uneven stress can easily occur during bolt tightening, causing the upsetting head to shift during operation and thus affecting the dimensional accuracy of flange upsetting. Utility Model Content

[0003] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stainless steel flange upsetting device, which can effectively solve the problems in the existing technology.

[0004] Technical solution

[0005] This utility model provides a stainless steel flange upsetting device, including a frame structure. The frame structure includes two sets of side frames and a truss fixed to the top of the two sets of side frames. A pressing power assembly is fixed to the top of the truss. The bottom end of the pressing power assembly is fixedly connected to a power shaft. A pressing head is sleeved and fixed on the outside of the power shaft. A mold assembly is fixed between the two sets of side frames. The mold assembly includes a side plate fixed to the outside of the two sets of side frames, a placement plate fixed to the top of the two sets of side plates, a connecting block fixed in the middle of the placement plate, and a pressing mold fixed in the middle of the connecting block. The pressing mold is placed at the bottom of the pressing head.

[0006] Furthermore, a connecting ring is fixed to the top of the pier head, and a circular hole is opened through the middle of both the connecting ring and the power shaft. The two sets of circular holes are fixedly connected by connecting bolts.

[0007] Furthermore, both sets of side frames have a through-hole in the middle, and the two sides of the two sets of side plates are fixed to the outside of the positioning hole by positioning rods. The middle of the placement plate has a docking hole, and the bottom of the connecting block is integrally fixed with a threaded column structure. The threaded column is inserted into the docking hole and fixed to the bottom of the placement plate by a locking nut.

[0008] Furthermore, a slot is provided in the middle of the connecting block, and a docking post is fixed at the bottom of the pressing mold, the docking post being inserted into the slot.

[0009] Furthermore, the positioning holes are arranged in multiple sets in a linear array on the two sets of side frames.

[0010] Furthermore, the top of the placement plate and the bottom of the connecting block are both corrugated structures that can be mated together.

[0011] Beneficial effects

[0012] In this invention, a connecting ring is installed at the top of the upsetting head, and a connecting bolt is used to fix the head in place by engaging the connecting ring with the round hole in the middle of the power shaft. Compared with traditional welding or multiple bolt connections, this not only simplifies the installation structure but also ensures the coaxiality of the upsetting head and the power shaft through the positioning and guiding effect of the round hole, effectively preventing the upsetting head from shifting during operation and improving the dimensional accuracy of flange upsetting. Furthermore, the detachable design of the connecting bolts makes the upsetting head replacement more convenient; it can be replaced simply by unscrewing the connecting bolts without disassembling the entire device, significantly shortening maintenance and replacement time and reducing operational difficulty.

[0013] In this device, multiple sets of positioning holes linearly arrayed in the middle of the two sets of side frames, combined with the positioning rod insertion and fixing structure on both sides of the side plates, allow the mold assembly to be flexibly adjusted in overall height by selecting positioning holes of different heights according to the upsetting requirements of flanges of different specifications. This adjustment method does not require replacing the entire mold support set; it only requires pulling out the positioning rods, adjusting the position of the side plates, and then re-inserting and fixing them. The operation is simple and quick, which not only reduces equipment replacement costs but also significantly shortens the production changeover cycle, improves the adaptability of the device to the production of flanges of multiple specifications, and increases production efficiency.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A stainless steel flange upsetting device, see attached figure. Figure 1 -Appendix Figure 5 The system includes a support frame structure 1, which includes two sets of side frames 11 and a truss 13 fixed to the top of the two sets of side frames 11. A pressing power assembly 2 is fixed to the top of the truss 13. The bottom of the pressing power assembly 2 is fixedly connected to the power shaft 21. A pressing head 23 is fixedly fitted on the outside of the power shaft 21. A mold assembly 3 is fixed between the two sets of side frames 11. The mold assembly 3 includes a side plate 31 fixed to the outside of the two sets of side frames 11, a placement plate 32 fixed to the top of the two sets of side plates 31, a connecting block 34 fixed to the middle of the placement plate 32, and a pressing mold 33 fixed to the middle of the connecting block 34. The pressing mold 33 is placed at the bottom of the pressing head 23.

[0020] The connection structure between all components of this device has been optimized. From the precise connection between the upsetting head 23 and the power shaft 21, to the flexible adjustment and stable fixation of the mold assembly 3, and the precise assembly of the upsetting mold 33, each link works together to form a stable and reliable overall working system. In long-term, high-frequency upsetting operations, each component is subjected to uniform stress, effectively reducing component wear or damage caused by structural instability and extending the overall service life of the device. At the same time, the stable working state further ensures the continuity and stability of the flange upsetting process, providing a strong guarantee for the efficient production of high-quality flange products.

[0021] A connecting ring 24 is fixed to the top of the upsetting head 23. Both the connecting ring 24 and the power shaft 21 have through holes 241 in their middle sections. The two sets of holes 241 are connected by connecting bolts 22. This device, by setting a connecting ring 24 at the top of the upsetting head 23 and using the connecting ring 24 and the through holes 241 in the middle of the power shaft 21 with connecting bolts 22 for fixation, simplifies the installation structure compared to traditional welding or multiple bolt connections. Furthermore, the positioning and guiding effect of the holes 241 ensures the coaxiality of the upsetting head 23 and the power shaft 21, effectively preventing the upsetting head 23 from shifting during operation and improving the dimensional accuracy of flange upsetting. Simultaneously, the detachable design of the connecting bolts 22 makes the replacement of the upsetting head 23 more convenient. It eliminates the need to disassemble the entire device; replacement can be completed simply by unscrewing the connecting bolts 22, significantly shortening maintenance and replacement time and reducing operational difficulty.

[0022] Both sets of side frames 11 have positioning holes 12 through their middle sections. The two sides of the two sets of side plates 31 are fixed to the outside of the positioning holes 12 by positioning rods 311. The middle of the placement plate 32 has a mating hole 321. A threaded post 331 is integrally fixed to the bottom of the connecting block 34. This threaded post 331 is inserted into the mating hole 321 and fixed to the bottom of the placement plate 32 by a locking nut 342. The middle of the connecting block 34 has a slot 341, and the bottom of the pressing mold 33 is fixed... A connecting post 332 is inserted into a slot 341. The slot 341 in the middle of the connecting block 34 and the connecting post 332 at the bottom of the upsetting die 33 are designed to cooperate to form a precise positioning and guiding structure. During assembly, the connecting post 332 can be directly inserted into the slot 341 to quickly align the center line of the die with that of the connecting block 34, effectively ensuring the coaxiality of the center line of the die and the center line of the power shaft 21, avoiding uneven stress on the flange during upsetting, and reducing the occurrence of quality problems. At the same time, the insertion structure of the connecting post 332 and the slot 341 makes the disassembly and replacement of the die more convenient. No special tools are required; disassembly can be completed simply by pulling the die upwards, reducing the difficulty of operation, further shortening the production auxiliary time, and improving the overall production efficiency.

[0023] Multiple sets of positioning holes 12 are linearly arrayed on the two sets of side frames 11. These multiple sets of positioning holes 12, linearly arrayed in the middle of the two sets of side frames 11, work in conjunction with the positioning rods 311 inserted and fixed on both sides of the side plate 31. This allows the mold assembly 3 to be assembled according to the upsetting requirements of different flange specifications by selecting positioning holes 12 of different heights, flexibly adjusting the overall height position of the mold assembly 3. This adjustment method does not require replacing the entire mold support set; it only requires pulling out the positioning rods 311, adjusting the position of the side plate 31, and then re-inserting and fixing them. The operation is simple and quick, not only reducing equipment replacement costs but also significantly shortening the production changeover cycle, improving the adaptability of the device to the production of multiple flange specifications, and increasing production efficiency.

[0024] Both the top of the placement plate 32 and the bottom of the connecting block 34 have a corrugated structure that can be mated. This corrugated design significantly increases the contact area and engagement compared to traditional flat-fit connections, effectively preventing slippage or displacement of the connection surface under high-frequency upsetting pressure. Simultaneously, the threaded post 331 at the bottom of the connecting block 34 is inserted into the mating hole 321 of the placement plate 32 and secured by a locking nut 342, forming a double-fixing structure that further enhances the connection stability between the connecting block 34 and the placement plate 32. This design ensures that the upsetting die 33 maintains a stable position during long-term operation, avoiding flange dimensional deviations caused by die offset and guaranteeing consistent flange product quality.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
