Description

Technical Field

[0001] The invention belongs to the technical field of long-neck flange processing, in particular to a shaping device and a shaping method for long-neck flange processing. Background Art

[0002] The long-neck flange is a special structural design in flange connection. Its characteristic is that the length of the flange neck (that is, the part connected to the pipe or equipment) is significantly longer than that of the standard flange. It is usually used in scenarios that require larger connection spacing or special installation conditions. Its design improves the overall rigidity and load-bearing capacity by lengthening the neck structure. It is suitable for complex working conditions such as high pressure, high temperature or low temperature.

[0003] In the prior art, the sealing surface in the long-neck flange is the surface that fits against the gasket during installation to ensure sealing. The flange end face of the long-neck flange is the opposite surface when the bolt is installed, which can effectively ensure fixed fit and secondary sealing. However, in the prior art, the sealing surface and the flange end face are both polished using a friction wheel or the like. However, the existing polishing method will result in a high surface roughness. At the same time, the residual tensile stress that may be generated by polishing will affect the sealing of the long-neck flange in the later stage. Moreover, the polishing operation requires manual participation. However, the weight of the long-neck flange is too high, and operations such as its falling will cause personal injury. Manual operation is dangerous.

[0004] To this end, the present invention provides a shaping device and a shaping method for processing a long-neck flange. Summary of the Invention

In addition, the grinding operation requires manual participation, but the weight of the long-neck flange 17 is too high, and operations such as its falling will cause personal injury, and manual operation is dangerous. For this reason, when the present invention is working, the long-neck flange 17 is supported by a U-shaped manipulator 16 (the prior art is not described in detail, and only the parts at the clamping position are shown in the drawings of the specification), and then the long-neck flange 17 is placed in the first open groove 14 through the T-shaped through groove 12, and then the long-diameter tube of the long-neck flange 17 is clamped and positioned by rotating the clamping piece, and then the U-shaped manipulator 16 is restored to its original position. The flange 17 is in a fixed state. The first hydraulic cylinder 15 drives the rolling assembly through the hydraulic rod to cover the sealing surface 18 and the flange end face 19, and then drives the long-neck flange 17 to rotate by rotating the clamping part, thereby completing the rolling and shaping of the sealing surface 18 and the flange end face 19 of the long-neck flange 17. The rolling treatment of the rolling assembly allows the rolling to refine the surface grains of the material and form a dense fiber structure, thereby improving the wear resistance. At the same time, the fatigue strength is improved through the residual compressive stress. At the same time, the rolling process can form cold-work hardened water lines on the flange surface, which not only improves the surface hardness, but also enhances the sealing fit through the microstructure. The entire process is a mechanical intelligent operation, which effectively avoids human participation and greatly reduces the risk of work.

[0038] The rolling assembly includes a first fixed block 2; the first hydraulic cylinder 15 is fixedly connected to the first fixed block 2 through a hydraulic rod; the first fixed block 2 is connected to sliding blocks 21 on both sides through connecting pieces; a cross groove 22 is provided at the bottom end of the first fixed block 2, and the cross groove 22 is slidably connected to the first rolling block 23; an I-shaped slide groove 24 is provided at the bottom end of the sliding block 21; a second rolling block 25 is slidably connected in the I-shaped slide groove 24; the bottom ends of the first rolling block 23 and the second rolling block 25 are both provided with multiple groups of rolling grooves 38, and the multiple groups of rolling grooves 38 are all circular grooves; a rolling ball 37 rolls in the rolling groove 38, and the opening diameter of the rolling groove 38 is smaller than the diameter of the rolling ball 37; multiple The center point of the rolling ball 37 is in a dislocated state; the first rolling block 23 and the second rolling block 25 slide through the sliding member; during operation, after the long-necked flange 17 is clamped and fixed by the rotating clamping member, the first hydraulic cylinder 15 drives the first fixed block 2 and the sliding block 21 to move downward, so that the rolling balls 37 on the first rolling block 23 and the second rolling block 25 are pressed and fitted on the sealing surface 18 and the flange end face 19 of the long-necked flange 17 (long-necked flange 17 of a single size), and then the long-necked flange 17 is rotated by rotating the rotating clamping member, thereby completing the rolling operation of the sealing surface 18 and the flange end face 19, wherein the setting of the rolling groove 38 and the rolling ball 37 can refer to the setting of the ballpoint pen tip.

[0039] The sliding member includes an annular opening block 3; an annular opening block 3 is rotatably connected to the supporting circular plate 13; the cross section of the annular opening block 3 is an inverted L-shaped; an annular opening corrugated groove 31 is provided on the upper and lower surfaces of the inner wall of the annular opening block 3; a second opening groove 32 is provided on the side walls on both sides of the opening of the annular opening block 3, and the second opening groove 32 and the annular opening corrugated groove 31 are connected to each other; a first guide column 33 is fixed to the annular inner wall of the supporting circular plate 13, and a first sliding column 34 is slidably sleeved on the outer wall of the first guide column 33, the top end of the first sliding column 34 passes through the sliding first rolling block 23, and the bottom end of the first sliding column 34 slides on The annular opening corrugated groove 31 on the upper side of the annular opening block 3; a pair of symmetrically distributed second guide columns 331 are fixedly connected to the annular inner wall of the support circular plate 13; a U-shaped sliding column 35 is slidably sleeved on the outer wall of the second guide column 331; the long rod of the U-shaped sliding column 35 passes through the sliding second rolling block 25, and the short rod end of the U-shaped sliding column 35 slides in the annular opening corrugated groove 31 on the lower side of the annular opening block 3; the annular opening block 3 is rotated by the power unit; a sliding groove 36 is formed on the second rolling block 25, and the sliding groove 36 and the I-shaped slide groove 24 are connected to each other, and the long rod of the U-shaped sliding column 35 slides in the sliding groove 36;

[0040] The power unit includes a second ring gear 42; a group of teeth 45 are fixedly connected to the outer wall of the annular opening block 3; a second gear 44 is rotatably connected to the support circular plate 13, and a pair of symmetrically distributed first gears 43 are rotatably connected to the support circular plate 13, and the pair of first gears 43 are meshed with the teeth 45 of the annular opening block 3; the pair of first gears 43 are symmetrically arranged about the second gear 44, and the second gear 44 and the pair of first gears 43 are meshed with each other; the distance between the center points of the pair of first gears 43 is greater than the opening distance of the annular opening block 3; a first servo motor 4 is fixedly connected to the inner wall of the bottom end of the box body 1; a first rotating column 41 is fixedly connected to the output end of the first servo motor 4; a second ring gear 42 is fixedly connected to the outer wall of the first rotating column 41; the second ring gear 42 and the second gear 44 are meshed with each other;

[0041] During operation, the first servo motor 4 works, thereby driving the first rotating column 41 to rotate. Since the second ring gear 42 and the second gear 44 are meshed with each other, the second gear 44 and a pair of first gears 43 are meshed with each other, and a pair of first gears 43 are meshed with the teeth 45 of the annular opening block 3, thereby driving the annular opening block 3 to rotate. The rotation of the annular opening block 3 will drive the first sliding column 34 and the U-shaped sliding column 35 to slide on the annular opening corrugated groove 31. At the same time, the setting of the annular opening corrugated groove 31 allows the first rolling block 23 and the second rolling block 25 to swing back and forth for rolling operation. Because the centers of the multiple groups of rolling balls 37 are in a staggered state, it is ensured that the sealing surface 18 and the flange end face 19 can be fully covered and rolled by the rolling balls 37. (Because the contact between the rolling ball 37 and the sealing surface 18 and the flange end face 19 is point contact, if the first rolling block 23 and the second rolling block 25 do not swing back and forth, the rolling comprehensiveness will be insufficient), and because the distance between the center points of a pair of first gears 43 is greater than the opening distance of the annular opening block 3, it can ensure that the annular opening block 3 can always be in a complete rotation state and will not be unable to rotate 360° due to the opening situation; at the same time, after the rolling of the long-neck flange 17 is completed, the positions of the annular opening block 3 and the first opening groove 14 are made to correspond to each other again, and the distance between the pair of second rolling blocks 25 is at the maximum (the short rod end of the U-shaped sliding column 35 is located at the center position of the protruding groove of the annular opening corrugated groove 31).

[0044] During operation, in the initial state without the long-neck flange 17 being inserted, the first fixed block 2 is at the bottom position of the hydraulic rod of the first hydraulic cylinder 15, and at the same time, due to the arrangement of the sliding block 21, the lower pressure plate 61, the insertion column 62 and the insertion groove 63, the lower pressure plate 61 will fit the bottom end of the first through groove 6 (the weight of the sliding block 21 itself), and the sliding block 21, under the action of the spring force on the insertion column 62, makes the side wall of the I-shaped through groove at the bottom end of the sliding block 21 and the side wall of the second rolling block 25 fit each other (when the long-neck flange 17 is not inserted, the short rod end of the U-shaped sliding column 35 is located at the center position of the protruding groove of the annular open corrugated groove 31, and the distance between the pair of second rolling blocks 25 is the maximum). At this time, the distance between the pair of sliding blocks 21 is the maximum, and the first inclined surface 65 of the inverted L-shaped plate 65 is 6 has not left the inclined surface of the inverted right-angled trapezoidal groove 64. In order to ensure the position accuracy of the pair of sliding blocks 21, when the long-neck flange 17 is fixed by rotating the clamping piece, the first hydraulic cylinder 15 drives the first fixed block 2 and the sliding block 21 to move downward through the hydraulic rod, and the rolling ball 37 of the second rolling block 25 will first contact the flange end surface 19. Then the first hydraulic cylinder 15 continues to drive the hydraulic rod to move downward, allowing the first inclined surface 66 of the inverted L-shaped plate 65 to slide down the inclined surface of the inverted right-angled trapezoidal groove 64, allowing the pair of sliding blocks 21 to move toward each other, and then allowing the side wall of the grinding column 68 on the sliding block 21 to fit the protruding side wall of the sealing surface 18.

Then, because the first ring gear 52 and the annular long spur gear 53 are engaged with each other, the first rotating column 41 can drive the three-jaw chuck 51 to rotate, wherein the three-jaw chuck 51 is a prior art and its internal structure is not explained.

When the long neck flange 17 is placed in the first opening groove 14 by the U-shaped manipulator 16, the long neck flange 17 is placed in the first opening groove 14. The flange of the neck flange 17 is located above the roller 86 as a whole, and then the U-shaped manipulator 16 moves downward, so that the flange of the long neck flange 17 (the long neck flange 17 is composed of a flange and a long diameter tube) is in a state of pressing the roller 86, and then clamped by the three-jaw chuck 51. When the long neck flange 17 is rotated by the three-jaw chuck 51 in the later stage, the roller 86 is pressed down, so the distance sensor 87 is used for distance measurement. If the horizontal placement state of the long neck flange 17 is broken and tilted, the distance of the distance sensor 87 will change, and then the shutdown operation will be performed. Then, the door body 11 is opened for debugging, and the distance sensor 87 is used for early warning, so that the shutdown operation can be performed in the first time to avoid deterioration of the working condition.

[0048] A shaping method for processing a long-neck flange, which uses the above-mentioned shaping device for processing a long-neck flange, and the steps of the method are as follows:

[0049] S1: The long neck flange 17 in the external environment is supported by the U-shaped manipulator 16, and then the long neck flange 17 is placed into the first opening groove 14 through the T-shaped through groove 12;

[0050] S2: The long diameter tube of the long neck flange 17 is clamped and positioned by rotating the clamping member, and then the U-shaped manipulator 16 is restored to its original position. The first hydraulic cylinder 15 drives the rolling assembly through the hydraulic rod to cover the sealing surface 18 and the flange end surface 19;

[0051] S3: The long-neck flange 17 is then rotated by rotating the clamping part to complete the rolling and shaping of the sealing surface 18 and the flange end face 19 of the long-neck flange 17. After the rolling is completed, the rolling assembly rises, and the long-neck flange 17 that has been rolled and shaped is taken out by the U-shaped manipulator 16.

[0052] Working principle: The U-shaped manipulator 16 (existing technology, no detailed description is given, only the parts at the clamping position are shown in the drawings of the specification) supports the long neck flange 17, and then puts the long neck flange 17 into the first open groove 14 through the T-shaped through groove 12, and then clamps and positions the long diameter tube of the long neck flange 17 by rotating the clamping piece, and then restores the U-shaped manipulator 16 to its original position, the long neck flange 17 is in a fixed state, the first hydraulic cylinder 15 drives the rolling assembly through the hydraulic rod to cover the sealing surface 18 and the flange end face 19, and then drives the long neck flange 17 to rotate by rotating the clamping piece, thereby completing the rolling shaping process of the sealing surface 18 and the flange end face 19 of the long neck flange 17, and the rolling process of the rolling assembly allows the rolling to make the surface grains of the material The fiber structure is refined and dense, and the wear resistance is improved. At the same time, the fatigue strength is improved through residual compressive stress. At the same time, the rolling process can form cold-work hardened water lines on the flange surface, which not only improves the surface hardness, but also enhances the sealing fit through the microstructure. The whole process is mechanically intelligent operation, which effectively avoids manual participation and greatly reduces the risk of work. After the long-neck flange 17 is clamped and fixed by the rotating clamp, the first hydraulic cylinder 15 drives the first fixed block 2 and the sliding block 21 to move downward, so that the rolling balls 37 on the first fixed block 2 and the sliding block 21 are pressed and fitted on the sealing surface 18 and the flange end face 19 of the long-neck flange 17 (single-size long-neck flange 17), and then the long-neck flange 17 is rotated by rotating the rotating clamp, and then Complete the rolling operation of the sealing surface 18 and the flange end face 19; the first servo motor 4 works, thereby driving the first rotating column 41 to rotate, because the second ring gear 42 and the second gear 44 are engaged with each other, the second gear 44 and a pair of first gears 43 are engaged with each other, and a pair of first gears 43 are engaged with the teeth 45 of the annular opening block 3, thereby driving the annular opening block 3 to rotate, and the rotation of the annular opening block 3 will drive the first sliding column 34 and the U-shaped sliding column 35 to slide on the annular opening corrugated groove 31. At the same time, the setting of the annular opening corrugated groove 31 allows the first rolling block 23 and the second rolling block 25 to swing back and forth for rolling operation, and because the centers of the multiple groups of rolling balls 37 are in a staggered state, it is ensured that the sealing surface 18 and the flange end face 19 can be rolled. The ball 37 is fully covered by the rolling (because the contact between the rolling ball 37 and the sealing surface 18 and the flange end face 19 is point contact, if the first rolling block 23 and the second rolling block 25 do not swing back and forth, the rolling comprehensiveness will be insufficient). At the same time, because the distance between the center points of the pair of first gears 43 is greater than the opening distance of the annular opening block 3, it can ensure that the annular opening block 3 can always be in a complete rotation state and will not be unable to rotate 360° due to the opening situation; at the same time, after the rolling of the long-neck flange 17 is completed, the positions of the annular opening block 3 and the first opening groove 14 are again made to correspond to each other, and the distance between the pair of second rolling blocks 25 is at the maximum (the short rod end of the U-shaped sliding column 35 is located at the center of the protruding groove of the annular opening corrugated groove 31);To ensure the accurate positioning of the pair of sliding blocks 21, when the long-neck flange 17 is fixed by rotating the clamping member, the first hydraulic cylinder 15 drives the first fixed block 2 and sliding block 21 downward via the hydraulic rod. The rolling ball 37 of the second rolling block 25 first contacts the flange end surface 19. The first hydraulic cylinder 15 then continues to drive the hydraulic rod downward, allowing the first inclined surface 66 of the inverted L-shaped plate 65 to slide down the inclined surface of the inverted right-angled trapezoidal groove 64, allowing the pair of sliding blocks 21 to move toward each other. This allows the side walls of the grinding column 68 on the sliding block 21 to fit against the protruding side walls of the sealing surface 18. At the same time, the grinding surface at the bottom of the grinding column 68 fits against the flange end surface 19, ensuring comprehensive grinding.
