Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel pipe shearing, in particular to a shearing machine for processing stainless steel cooling water pipes. BACKGROUND

[0002] The stainless steel cooling water pipe is widely used in fluid conveying systems in various fields due to its excellent corrosion resistance, strength and sanitary performance. Before installation, it needs to be cut to size, and the cutting quality directly affects the sealing reliability of subsequent welding and expansion joint and the system operation efficiency. In the prior art, the traditional hydraulic or mechanical shearing machine is mainly relied on to implement the punching of the pipe by the vertically downward pressing arc-shaped die. However, when dealing with high-strength and high-toughness materials such as stainless steel, the inherent shortcomings are more obvious. First, the huge concentrated load generated by vertical shearing is easy to cause the pipe opening to be concave or to collapse and plastically deform, and the inner wall is easy to produce large flanging burrs. Second, for large-diameter and thick-walled stainless steel pipes, the required shearing tonnage increases dramatically, resulting in large equipment and high energy consumption. Finally, the shearing, burr removal and pipe quality detection processes need to be frequently transferred and fed, which reduces the production efficiency and increases the production management and site costs.

[0027] The inner wall of the stainless steel tube 001 is supported by a support unit. The height of the support unit is adjusted by a lifting unit to accommodate stainless steel tubes 001 of different diameters. The support unit is flipped by a flipping unit to facilitate unloading after shearing.

[0028] The support unit includes: The second translation component 13 is connected to the mounting plate 12, and the second translation component 13 consists of an electric slide rail and two electric sliders. A first fixing plate 17 is connected to the second translation component 13, and an installation cylinder 20 is rotatably connected inside the first fixing plate 17.

Several support components are provided, all of which are connected to the conveying pipe 19; Each of the first fixing plate 17 and the second fixing plate 18 is connected to a driving assembly, which is used to drive the conveying pipe 19 and the mounting cylinder 20 to rotate, respectively.

[0029] By controlling the electric slider to slide on the electric slide rail, the first fixed plate 17 and the second fixed plate 18 are moved.

[0030] The drive assembly on the first fixed plate 17 includes: The drive motor 46 is fixedly connected to the first fixing plate 17; The first spur gear 47 is fixedly connected to the output shaft of the drive motor 46; and The second spur gear 48 is fixedly connected to the mounting cylinder 20 and meshes with the first spur gear 47.

[0031] The support assembly includes a pneumatic cylinder 30 connected to the delivery pipe 19, a piston rod 31 slidably connected to the pneumatic cylinder 30, and a support rod 32 fixedly connected to the piston rod 31. The pneumatic cylinder 30 has an exhaust port at the end away from the delivery pipe 19. Among them, the outer ring surface of the support rod 32 is provided with an anti-slip plate on the side away from the center of the conveying pipe 19; a number of ring-shaped support components are arranged as a group, and the conveying pipe 19 is provided with two groups of support components, and there is a gap between the two groups of support components.

[0032] The piston rod 31 is controlled to move within the pneumatic cylinder 30 by an external pneumatic control system, thereby controlling the support rod 32 to support the inner wall of the stainless steel tube 001. Anti-slip plates are provided to enhance the friction between the support rod 32 and the inner wall of the stainless steel tube 001.

[0033] The support assembly also includes a third electric push rod 43 fixedly connected to the mounting cylinder 20, a limiting plate 44 fixedly connected to the telescopic end of the third electric push rod 43, and a distance measuring sensor 45 connected to the limiting plate 44.

[0034] The distance between the distance sensor 45 and the first fixed plate 17, i.e. the moving distance of the limiting plate 44, is monitored by the distance sensor 45, so that the distance compensation can be performed when the second translation component 13 drives the first fixed plate 17 and the second fixed plate 18 to move.

[0035] The support assembly also includes a storage cylinder 34 fixedly connected to the delivery pipe 19, a control valve 37 communicating with the delivery pipe 19, a push plug 36 slidably connected to the storage cylinder 34, an infusion pipe 35 communicating with the storage cylinder 34, and a flaw detection mechanism connected to the storage cylinder 34, wherein the infusion pipe 35 is provided with a multi-stage telescopic part 3501.

[0036] By activating the external pneumatic control system, the push plug 36 is moved, extruding the coupling agent stored in the storage cylinder 34 into the inner wall of the stainless steel tube 001. Then, the flaw detection mechanism is activated, and the delivery pipe 19 and its connected parts are rotated by the drive assembly, thereby performing flaw detection on the inner wall of the stainless steel tube 001.

[0037] The flaw detection mechanism also includes a second electric push rod 38 fixedly connected to the storage cylinder 34, an elastic telescopic rod 42 fixedly connected to the telescopic end of the second electric push rod 38, a third fixing plate 39 fixedly connected to the telescopic end of the elastic telescopic rod 42, an ultrasonic probe 41 connected to the third fixing plate 39, and a liquid outlet head 40 connected to the multi-stage telescopic part 3501.

[0038] The support unit also includes two grinding mechanisms connected to the third fixing plate 39 and the mounting cylinder 20 respectively, and a lifting mechanism connected to the mounting cylinder 20; The lifting mechanism includes two lifting components 22 connected to the mounting cylinder 20 and a sliding plate 23 connected to the two lifting components 22. The sliding plate 23 is slidably connected to the mounting cylinder 20. The lifting component 22 is composed of an electric slide rail and an electric slider. The grinding mechanism includes two connecting plates 24 fixedly connected to the sliding plate 23 and two grinding components connected to the two connecting plates 24; The grinding component includes two torsion spring shafts 25 connected to the two connecting plates 24 respectively, a fixed block 26 connected to the two torsion spring shafts 25, a drive motor 27 connected to the fixed block 26, a rotating seat 28 rotatably connected to the fixed block 26, and a grinding roller 29 screwed to the rotating seat 28. The output shaft of the drive motor 27 is fixedly connected to the rotating seat 28.

[0039] During installation, the external pneumatic control system is installed in the mounting section 1201. Each connecting pipe 21 is connected via a conduit. The external pneumatic control system controls the piston rod 31 to slide within the pneumatic cylinder 30, thereby controlling the contact between the support rod 32 and the inner wall of the stainless steel pipe 001. This provides support to the inner wall of the stainless steel pipe 001 through several support rods 32, preventing indentation and collapse of the pipe opening during shearing. It can also accommodate stainless steel pipes 001 of different diameters. Before operation, the arc-shaped blade on the shearing blade 4 can be replaced to accommodate different diameter stainless steel pipes 001. During operation, the external unloading device pushes multiple stainless steel pipes 001 between the receiving rollers 6, which in turn support the stainless steel pipes 001. The support is adjusted according to the diameter of the stainless steel pipe 001. By controlling the extension and retraction of the first electric push rod 11, the connecting frame 15 and its connected parts are raised and lowered, thereby adjusting the height of the support assembly so that the center of the conveying pipe 19 is aligned with the center of the stainless steel pipe 001. Based on the required cutting length, the second translation component 13 corresponding to each stainless steel pipe 001 is activated. The second translation component 13 drives the first fixing plate 17 and the second fixing plate 18 to move towards the port of the stainless steel pipe 001, allowing the installation cylinder 20 to be inserted into the stainless steel pipe 001. The limiting plate 44 then limits the movement of the stainless steel pipe 001. Thus, depending on the cutting length, the second translation component 13 drives the first fixing plate 17 and the second fixing plate 18 to move towards the port of the stainless steel pipe 001, allowing the installation cylinder 20 to be inserted into the stainless steel pipe 001. The limiting plate 44 then limits the movement of the stainless steel pipe 001. The cutting length can be controlled by the moving distance. Then, the second translation component 13 is controlled to move the second fixed plate 18, so that the conveying pipe 19 slides within the mounting block 14 and mounting cylinder 20, making the gap between the two sets of support components on the conveying pipe 19 aligned with the two shearing blades 4. Next, the external pneumatic control system is activated, so that multiple support rods 32 of the two sets of support components contact the inner wall of the stainless steel pipe 001 with a preset pressure for support. At the same time, the first translation component 7 is controlled to move the corresponding support plate 8 and support roller 9, so that each stainless steel pipe 001 has two support rollers 9 on its right end for support, ensuring the stability of the stainless steel pipe 001 during shearing. Then, the hydraulic push rod 3 is controlled to extend and push the two shearing blades 4 closer together to cut multiple stainless steel pipes 001. During shearing, the shearing blade 4 feeds the material while simultaneously controlling the drive assembly on the second fixed plate 18 to drive the conveying pipe 19 and its connected parts to rotate. This, in turn, drives the stainless steel pipe 001 to rotate via multiple support rods 32. The rotation of the stainless steel pipe 001, in turn, drives the receiving roller 6 and the support roller 9 to rotate via friction. This rotational contact prevents the receiving roller 6 and the support roller 9 from causing wear on the surface of the stainless steel pipe 001, enabling the simultaneous shearing of multiple stainless steel pipes 001. Compared to traditional vertical shearing, this method disperses the concentrated load into a progressive local load. Combined with the support rods 32 on the inner wall of the stainless steel pipe 001, this avoids pipe end deformation and excessive tonnage required for shearing, improving cut quality, significantly reducing waste, and extending the life of the shearing blade 4.

[0040] When the liquid outlet head 40 and the ultrasonic probe 41 are inserted into the inner wall of the stainless steel tube 001 along with the delivery pipe 19, the second electric push rod 38 is extended, causing the multi-stage telescopic part 3501 to extend, so that the liquid outlet head 40 and the ultrasonic probe 41 come into contact with and are squeezed against the inner wall of the stainless steel tube 001, thus compressing the elastic telescopic rod 42. Then, the control valve 37 is opened, and the external pneumatic control system is activated to push the push plug 36 to move, squeezing the coupling agent stored in the storage cylinder 34 into the inner wall of the stainless steel tube 001. Then, the ultrasonic probe 41 is activated, and the delivery pipe 19 and its connected parts are driven to rotate through the drive assembly. Then, the ultrasonic probe 41 is used to detect flaws in the inner wall of the stainless steel tube 001, thereby realizing the quality detection of the inner wall of the stainless steel tube 001 in the shearing preparation process, eliminating the additional transfer and loading / unloading processes required for the stainless steel tube 001 inspection, and improving work efficiency.

[0041] After shearing, the hydraulic push rod 3 retracts, causing the shearing blade 4 to reset. The second translation component 13 then moves the first fixed plate 17 and the second fixed plate 18 to the right, separating the sheared stainless steel tube 001 segment from the raw stainless steel tube 001. Next, the external pneumatic system controls the piston rod 31 to move the support rod 32 away from the inner wall of the stainless steel tube 001. Finally, the second translation component 13 moves the first fixed plate 17 and the second fixed plate 18 to the left, exposing the grinding mechanism on the third fixed plate 39 to the sheared stainless steel tube. Outside of section 001, the second electric push rod 38 is extended, causing the two grinding rollers 29 of the grinding mechanism to align with the inner and outer walls of the opening of the stainless steel tube 001. Then, the second translation component 13 is controlled to move the first fixed plate 17 and the second fixed plate 18 to the right, causing the two grinding rollers 29 to contact and be compressed with the inner and outer edges of the opening of the stainless steel tube 001, resulting in the torsion spring shaft 25 twisting. The design of the torsion spring shaft 25 allows the grinding mechanism to adapt to stainless steel tubes 001 with different wall thicknesses, enhancing its adaptability. Then... The stainless steel tube 001 is fixed to the inner wall by multiple support rods 32. Simultaneously, the drive assembly drives the conveying pipe 19 to rotate, which in turn drives the stainless steel tube 001 to rotate via the support rods 32. At the same time, the drive motor 27 controls the rotating seat 28 and the grinding roller 29 to rotate. The rotation direction of the grinding roller 29 is opposite to the rotation direction of the rotating seat 28, preventing the grinding roller 29 from detaching from the rotating seat 28. After the shearing process, the two grinding rollers 29, in conjunction with the rotation of the stainless steel tube 001, grind away the burrs at the sheared area, thus eliminating the need for... The subsequent transfer and loading / unloading processes required for grinding the stainless steel pipe 001 further improve work efficiency. After the shearing is completed, the stainless steel pipe 001 is fixed in place by multiple support rods 32. Then, the electric rotating shaft 16 is started. With the reference from front to back, the electric rotating shaft 16 rotates 180 degrees clockwise, which causes the sheared stainless steel pipe 001 segment to rotate 180 degrees along with the conveying pipe 19 and the mounting cylinder 20. Then, the multiple support rods 32 release the stainless steel pipe 001, and the stainless steel pipe 001 segment can be removed by the external material handling equipment.

[0042] When shearing the next section of stainless steel pipe 001, the lifting assembly 22 drives the sliding plate 23 to rise and fall, aligning the two grinding rollers 29 of the grinding mechanism on the sliding plate 23 with the inner and outer edges of the stainless steel pipe 001. Then, before shearing the next section, the grinding mechanism removes burrs from the inner and outer edges of the pipe opening, similar to the principle described above. This ensures that burrs are completely removed from both ends of each sheared section of stainless steel pipe 001, eliminating the need for subsequent transfer and loading / unloading steps. Finally, the coupling agent and grinding debris inside the stainless steel pipe 001 are cleaned uniformly. Therefore, for stainless steel pipes 001 with different wall thicknesses, in order to avoid the obstruction of the limiting plate 44, the two grinding rollers 29 of the grinding mechanism on the sliding plate 23 cannot contact the inner and outer edges of the pipe opening. Adjustment can be made by controlling the retraction of the third electric push rod 43 to drive the limiting plate 44 and the distance sensor 45 to move. At the same time, the distance between the distance sensor 45 and the first fixed plate 17, that is, the moving distance of the limiting plate 44, is monitored by the distance sensor 45. This facilitates distance compensation when the second translation component 13 drives the first fixed plate 17 and the second fixed plate 18 to move, ensuring the accuracy of the cutting length of the stainless steel pipe 001.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
