Description

Technical Field

[0001] The present invention relates to the technical field of bevel cutting of stainless steel pipes, and particularly to an automatic production device for stainless steel pipes. Background Art

[0002] Due to its corrosion resistance, high strength, and aesthetic appearance, stainless steel pipes are widely used in fields such as construction, chemical industry, petroleum, machinery manufacturing, automobile manufacturing, aerospace, etc. In these applications, the cutting and processing of stainless steel pipes are common technological requirements. Bevel cutting is an important processing method among them, used to manufacture pipe ends with specific angles to meet different installation and connection needs. During the automatic production of stainless steel pipes, especially in cold rolling and hot rolling processes, a large amount of lubricating oil is usually used to reduce friction, protect equipment, and improve production efficiency. These lubricating oils may remain on the surface of the steel pipes during processing, forming oil stains. However, during subsequent bevel cutting, the oil stains may burn or carbonize during cutting, forming an uneven heat distribution, resulting in an uneven cutting surface, burrs, or pits. Therefore, the cutting area needs to be cleaned.

[0003] The Chinese Patent Network disclosed a bevel cutting device for heat exchanger stainless steel pipes with the publication number: CN219324814U. This device is equipped with a lower clamping seat, an upper clamping seat, a guide rod, a U-shaped groove body, a screw rod, and a movable plate, which facilitates the fixation of one end of the stainless steel pipe. After the stainless steel pipe is cut once, the remaining stainless steel pipe is continuously moved to the cutting knife through a translation component for cutting until the stainless steel pipe is cut according to requirements, thus completing efficient pipe bevel cutting.

[0004] When the above bevel cutting device performs bevel cutting, its driving motor is fixedly connected and cannot be adjusted in angle, so that the cutting angle of the driving motor driving the cutting knife does not change, making it impossible for the stainless steel pipe to adjust the bevel cutting angle according to requirements, reducing the applicability of the bevel cutting device. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the problem that the above bevel cutting device cannot adjust the bevel cutting angle, the present invention is proposed.

After the angle of the cutting component is adjusted, when the cutting component is cutting, the adaptive touch plate can still be attached to the bottom side area of the cutting component. And a spring is provided between the top of the stabilizing block and the support rod. When the adaptive touch plate is not pressed, the stabilizing block can be restored.

[0012] As a preferred solution of the automatic stainless steel pipe production device of the present invention, wherein: A three-jaw chuck is installed on the top of the inclined cutting tabletop.

[0015] As a preferred embodiment of the automatic stainless steel pipe production device of the present invention, the following is provided: A cleaning ring is installed on the outer wall of the conveying frame. A reciprocating movement mechanism is connected between the stabilizing block and the cleaning ring. When the stabilizing block is pressed and moved downward by the bevel cutting mechanism, the reciprocating movement mechanism can drive the cleaning ring to move and clean along the direction of the end point of the bevel cutting of the stainless steel pipe.

[0016] As a preferred embodiment of the automatic stainless steel pipe production device of the present invention, the following is provided: The reciprocating movement mechanism includes: A guide plate is installed on the outer wall of a group of conveying frames near the bevel cutting surface of the stainless steel pipe at the top of the bevel cutting table.

After the angle adjustment, it can still automatically clamp the clamping parts of the stainless steel pipe, improving the stability during the cutting of the stainless steel pipe and making the clamping structure more suitable for the automatic bevel cutting process of stainless steel pipes. Second, before bevel cutting, the cleaning ring moves along with the downward movement of the stabilizing block, enabling the cleaning ring to automatically scrape off the oil stains on the bevel cutting area of the stainless steel pipe before bevel cutting. When the bevel cutting is completed and restored, it can also effectively remove the debris on the outer surface, thus avoiding scratches caused by the friction between the outer surface debris and the subsequent three-jaw chuck of the mobile end and one of the conveying frames.

[0029] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein.

The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0031] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure are locally enlarged out of the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein.

[0032] Embodiment 1 Referring to Figures 1-3 , which is the first embodiment of the present invention. This embodiment provides an automatic production device for stainless steel pipes, including an inclined cutting table 1, and also including an inclined support 11. Both sides of the top of the inclined support 11 are jointly supported by a lifting mechanism 111 and a rotating support frame 112 with a cutting support frame 12. The cutting support frame 12 is a set of rotating movable supports; The cutting support frame 12 is movably connected to the rotating support frame 112 through a pin shaft, and the axis of this pin shaft is the axis of rotation when the angle of the cutting support frame 12 is adjusted. One side of the cutting support frame 12 and the lifting mechanism 111 are jointly and movably connected to both ends of a connecting rod through a pin shaft respectively. At this time, when the lifting mechanism 111 moves upward, one side of the cutting support frame 12 is lifted upward by the lifting mechanism 111, and the other side of the cutting support frame 12 rotates on the rotating support frame 112, thereby causing the entire cutting support frame 12 to tilt, and further causing the angle of the cutting assembly 13 connected to the top side to change; The rotating end of the cutting support frame 12 is connected to a cutting assembly 13. The cutting end of the cutting assembly 13 is installed with a conveying frame 14 connected to the inclined cutting table 1. A stainless steel pipe is placed on the top side of the conveying frame 14, and multiple groups of conveying frames 14 are arranged on the inclined cutting table 1, and one group of conveying frames 14 is relatively close to the initial cutting end of the inclined cut.

[0033] Specifically, an output end 131 is installed at the end of the non-cutting end of the cutting assembly 13. During cutting, the output mechanism connected to the output end 131 inclines the cutting end of the cutting assembly 13 towards the stainless steel pipe for cutting.

[0034] Operation process: When obliquely cutting a stainless steel pipe, the height of one side of the cutting assembly 13 can be adjusted through the lifting mechanism 111 according to actual needs. At this time, the cutting assembly 13 rotates and moves on the rotating support frame 112, so that the inclination angle of the cutting assembly 13 can be changed. Subsequently, when cutting the stainless steel pipe, the output end 131 at one end of the cutting assembly 13 touches the cutting assembly 13 through the output mechanism, so that the cutting assembly 13 rotates and moves on the cutting support frame 12, and the cutting end of the cutting assembly 13 faces the stainless steel pipe side for oblique cutting.

[0035] Embodiment 2 Refer to Figures 1-7 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a support rod 2 is installed on the top side of the oblique cutting table 1. The support rod 2 is movably sleeved with a spring telescopic rod 21. The bottom end of the spring telescopic rod 21 is installed with a stabilizing block 22. The top end of the spring telescopic rod 21 is movably connected with an adaptive touch plate 23. A cleaning ring 32 is installed on the outer wall of the conveying frame 14. A reciprocating moving mechanism is connected between the stabilizing block 22 and the cleaning ring 32. The reciprocating moving mechanism can drive the cleaning ring 32 to move and clean along the direction of the end point of the oblique cutting of the stainless steel pipe when the stabilizing block 22 is pressed down by the oblique cutting mechanism. A three-jaw chuck 4 is installed on the top of the oblique cutting table 1. A rotating rod 42 is installed at the tightening end of the three-jaw chuck 4. The rotating rod 42 and the stainless steel pipe oblique cutting mechanism are connected through a connecting mechanism that is not affected by angle adjustment.

[0036] Specifically, the adaptive touch plate 23 and the top end of the spring telescopic rod 21 are connected through a universal joint 231. After the angle of the cutting assembly 13 is adjusted, when the cutting assembly 13 is cutting, its adaptive touch plate 23 can still fit with the bottom side area of the cutting assembly 13. And a spring is provided between the top of the stabilizing block 22 and the support rod 2. When the adaptive touch plate 23 is not pressed, the stabilizing block 22 can be restored.

[0037] Furthermore, a guide plate 3 is installed on the outer wall of a group of conveying frames 14 on the oblique cutting table 1 close to the oblique cutting surface. A sliding rod 31 is installed through the inner wall of the guide plate 3. One end of the sliding rod 31 is connected to the cleaning ring 32, and the other end of the sliding rod 31 is connected to a return block 33. A rotating disk 34 is installed on the outer wall of the guide plate 3. A transmission rod 35 is installed on the outer wall of the rotating disk 34. The transmission rod 35 is embedded in the return block 33. One side of the axis of the rotating disk 34 is connected with a gear 36. A toothed plate 37 is installed on the outer wall of the stabilizing block 22. And the toothed plate 37 meshes with the gear 36. And when the stabilizing block 22 is pressed down, the toothed plate 37 drives the gear 36 to rotate. The rotation of the gear 36 drives the transmission rod 35 of the rotating disk 34 to move, so that the transmission rod 35 drives the return block 33 to shift. When the stabilizing block 22 contacts the surface of the stainless steel pipe, the cleaning ring 32 connected to one side of the return block 33 also moves to the limit distance, that is, the terminal side of the oblique cutting surface.

[0038] Further, a rubber bladder 321 is installed on the inner wall of the cleaning ring 32. A sponge ring may be adhered to the joint surface between the rubber bladder 321 and the stainless steel pipe, which can slightly adsorb some oil cleaning liquid, thereby more effectively removing the oil stain on the surface of the stainless steel pipe. A flange 322 is installed on the inner wall of the cleaning ring 32, and the flange 322 is located on the side of the rubber bladder 321 close to the inclined area. The flange 322 can be fitted with the fitting pad 383, so that one side of the cleaning ring 32 and the storage ring 38 is sealed.

[0039] Further, a storage ring 38 is installed on the outer wall of one side of the conveying frame 14. A nozzle 381 is installed on the outer wall of the storage ring 38. A fitting ring 382 is installed at one end of one side of the storage ring 38. The diameter of the fitting ring 382 is slightly larger than the diameter of the cleaning ring 32. A fitting pad 383 is installed on the outer wall of the storage ring 38.

[0040] Further, a spring catch 41 is provided on one side of the three-jaw chuck 4. A pressure contact ring 47 is installed at the end of the rotating rod 42. A spiral groove 48 is provided on the inner wall of the pressure contact ring 47, and the rotating rod 42 is engaged with the spiral groove 48 through a convex ball, so that when the pressure contact ring 47 is pressed, a rotating force can be applied to the rotating rod 42, and the three-jaw chuck 4 is clamped to the stainless steel pipe by the rotation of the rotating rod 42.

[0041] Further, an inclined support plate 43 is installed on the outer wall of the cutting assembly 13. An arc groove 44 is provided on the outer wall of the inclined support plate 43. The arc groove 44 is concentric with the axis of the rotating support frame 112. A sliding disk 45 is slidably connected to the arc groove 44. A connecting block 46 is connected between the sliding disk 45 and the pressure contact ring 47 through a pin shaft.

[0042] All other structures are the same as those in Embodiment 1.

[0043] Working principle: When the angle of the cutting component 13 changes, since the arc-shaped groove 44 of the inclined support plate 43 is aligned with the axis of the angle adjustment of the cutting component 13, even when the angle of the cutting component 13 changes, the inclined support plate 43 thereof still remains connected to the sliding disk 45. When the cutting component 13 moves for cutting, the cutting component 13 drives the inclined support plate 43 to press the pressure contact ring 47 on the connecting block 46, and the pressure contact ring 47 then presses the rotating rod 42, causing the rotating rod 42 to rotate and move along the spiral groove 48 of the pressure contact ring 47. Furthermore, the rotating rod 42 rotates the tightening end of the three-jaw chuck 4, causing the spring catch 41 of the three-jaw chuck 4 to gradually clamp on the stainless steel pipe. At the same time, when the cutting component 13 approaches the stainless steel pipe, the bottom side of the cutting component 13 synchronously touches the adaptive touch plate 23, causing the spring telescopic rod 21 at the bottom side of the adaptive touch plate 23 to drive the stabilizing block 22 to move downward. The stabilizing block 22 and the spring catch 41 respectively clamp on one side of the initial section and the terminal section of the inclined cut of the stainless steel pipe. The spring telescopic rod 21 and the spring catch 41 have a certain moving gap, so that the cutting component 13 can continue the cutting action without being affected after the stainless steel pipe is clamped, thereby automatically clamping the two ends of the inclined cut of the stainless steel pipe, improving the stability of the inclined cut. When the stabilizing block 22 moves downward, the stabilizing block 22 drives the toothed plate 37 to move downward. The movement of the toothed plate 37 drives the gear 36 to rotate, and the rotation of the gear 36 drives the transmission rod 35 to start rotating around the axis, causing the transmission rod 35 to deflect and move the loop-shaped block 33. The deflection of the loop-shaped block 33 drives the sliding rod 31 to move, causing the cleaning ring 32 at one end of the sliding rod 31 to disengage from the receiving ring 38. The cleaning ring 32 gradually moves towards the terminal of the inclined cut. During the movement of the cleaning ring 32, the gas in the piston member 323 is pressurized and injected into the rubber bladder 321. At this time, the rubber bladder 321 tightly adheres to the outer surface of the stainless steel pipe. The continuous movement of the cleaning ring 32 enables the rubber bladder 321 to clean the inclined cut surface of the stainless steel pipe, scraping off the attached oil stains. And during the cutting process, the cleaning ring 32 is always located on the terminal side of the cut. A baffle can be provided on the outside of the cleaning ring 32 to block debris from flying to the other side of the cleaning ring 32. A baffle can also be provided on one side of the receiving ring 38 to block debris from entering the other area. At this time, the cutting debris will only fall in the area between the receiving ring 38 and the cleaning ring 32 (the shapes of the above two groups of baffles are designed according to actual needs to block debris). After the cutting is completed and the cutting component 13 moves upward, the toothed plate 37 returns and moves upward to drive the cleaning ring 32 to reset. The cleaning ring 32 performs a secondary scraping on the cleaning area, scraping off the chips attached to the outer surface of the stainless steel pipe. Then, when the stainless steel pipe continues to be conveyed forward, the outer surface of the stainless steel pipe will not be scratched due to the strong friction between the chips attached and the conveying device. When the cleaning ring 32 retracts into the receiving ring 38, one end of the cleaning ring 32 contacts the fitting ring 382.Moreover, the convex edge 322 on the cleaning ring 32 is in contact with the fitting pad 383 on the storage ring 38, so that the space between the cleaning ring 32 and the storage ring 38 is sealed. At this time, the nozzle 381 is supplied with water to spray the cleaning liquid, and its dirt is discharged through the sewage outlet provided on the storage ring 38, thus completing the work of a cleaning cycle.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
