Description

Technical Field

[0001] The present invention relates to the technical field of flange processing, and in particular to high-precision flange processing equipment for a heat exchanger piping system. Background Art

[0002] During the production and processing of flanges, metal blanks are often forged and then hot-pressed. Currently, patent No. CN02133268.1 discloses a flange processing and forming process, which is characterized in that a flange blank prototype is centrifugally cast using molten steel refined at 1650-1700°C. The centrifugal casting temperature is 1520-1550°C. The centrifugally cast flange blank prototype is pit-chilled at 500-600°C for 10-48 hours, and then naturally cooled to room temperature. The flange blank prototype is then turned to remove surface defects such as looseness, and then forged at 1180-1200°C. Finally, the flange is rough-turned and fine-turned to form a finished flange. The flange produced using the flange processing and forming process of the present invention is tested by ultrasonic testing and has no internal defects, showing a high quality level. The flange produced using the flange processing and forming process of the present invention is not only simple in process and low in cost, but also high in quality and long in service life. After the flange is pit-cooled, defects will appear on the surface and it needs to be turned. However, the existing flange turning equipment has the following problems:

[0003] 1. When the existing flange processing equipment is turning the inner ring of the flange, the outer ring of the flange needs to be fixed to maintain stability. Similarly, when turning the outer ring of the flange, the inner ring of the flange needs to be fixed. When the flange is large, it is difficult to switch the fixing device, which has low flexibility and is time-consuming and labor-intensive.

[0004] 2. Existing flange processing equipment uses a turning tool to turn a flange alone. Only the turning point of the turning tool is subjected to force, and the reverse direction is extremely unstable, causing the turning tool to vibrate as a whole and resulting in poor balance. This not only affects the turning accuracy of the flange, but also reduces the durability of the turning tool.

[0005] 3. During the flange turning process, chips will fly out, but the existing flange processing equipment does not deal with the flying chips, causing the workshop to be filled with chips, affecting the working environment;

[0006] 4. Existing flange processing equipment cannot realize the non-stop measurement function, and it is necessary to frequently stop the turning work for measurement. Summary of the Invention

[0010] Furthermore, the turning system includes a robotic arm and a turning tool; the workbench is equipped with the robotic arm; and the working part of the robotic arm is detachably connected to the turning tool.

[0011] Furthermore, the mounting plate, the fixing ring, the first electric push rod, the rotating wheel and the auxiliary fixing assembly are provided in two groups and are symmetrical front to back; the turning tool is a double-headed turning tool structure.

[0012] Furthermore, the working part of the robot arm is detachably connected to a baffle, and the baffle is located outside the turning tool; the baffle is in a "U" shape.

[0018] Beneficial effects: The present invention allows the operator to place the flange in a fixed space formed by four rotating wheels, and then control all the telescopic parts of the first electric push rods to push outward, thereby driving the rotating wheels on the corresponding sides to push out, so that the four rotating wheels contact and fix the flange. As the rotating wheels are pushed out more, the rotating wheels fix the flange more stably; at the same time, the telescopic parts of the first electric push rods can be controlled to drive the rotating wheels to be adaptively pushed out as the turning work progresses, so as to ensure that the flange is sufficiently stable during turning.

In this way, the purpose of adjusting and steering the flange is achieved without performing disassembly and assembly operations, avoiding tedious disassembly, adjustment, and proofreading operations, and effectively improving the turning efficiency of the flange.

[0020] When the scraper block rotates, it is in constant contact with the scraper plate. Since the scraper plate is connected to the connecting roller by a torsion spring, the torsion force of the torsion spring presses the scraper plate toward the side of the scraper block facing the scraper plate. When the scraper block rotates past, the scraper plate scrapes off the debris on the side of the scraper block facing the scraper plate, thereby cleaning and collecting the debris attached to the scraper block.

[0021] When the inner annular surface of the flange is turned, as the turning work proceeds, the inner diameter of the flange also increases, so that the telescopic part of the second electric push rod drives the connecting plate and the fixed wheel to gradually shrink to adapt to the inner diameter of the flange. As the distance between the two mounting blocks increases, more of the scale is exposed. In this way, the inner diameter data of the flange can be obtained according to the scale exposed by the scale, realizing non-stop detection and solving the problem of the existing method that the turning work needs to be frequently stopped for measurement during the turning work.

DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention. Example 1

[0038] A high-precision flange processing equipment for heat exchanger piping system, such as Figure 1-8As shown, it includes a workbench 1, a mounting plate 2, a fixing ring 3, a first electric push rod 4, a rotating wheel 5, a driving assembly, an auxiliary fixing assembly and a turning system; the workbench 1 is slidably connected to the mounting plate 2; the mounting plate 2 is connected to the fixing ring 3 through a connecting seat bolt; the fixing ring 3 is installed with four first electric push rods 4 groups distributed in a circular array, and each first electric push rod 4 group is composed of two first electric push rods 4 distributed front and back; the two first electric push rods 4 in each first electric push rod 4 group are connected to the rotating wheel 5 by the telescopic parts that rotate together, and the rotating wheel 5 is provided with a driving motor, and the fixing operation of the flange 001 is realized by the rotating wheels 5 distributed in four circular arrays; the workbench 1 is installed with a driving assembly, and the driving assembly is used to drive the mounting plate 2 and its connecting parts to move forward and backward; the fixing ring 3 is installed with an auxiliary fixing assembly, and the flange 001 is auxiliary fixed on the basis of the rotating wheel 5 by the auxiliary fixing assembly, so that the flange 001 is more stable and the steering operation of the flange 001 is realized; the mounting plate 2 is installed with a turning system, and the flange 001 is turned by the turning system.

[0039] like Figure 5-7 As shown, the auxiliary fixing assembly includes a second electric push rod 111, a hollow connecting box 112, a third electric push rod 113, a connecting plate 114, a fixed wheel 115 and an electric turntable 116; the inner surface of the fixing ring 3 is equipped with two electric turntables 116 that are centrally symmetrically distributed; the output parts of the two electric turntables 116 are each equipped with a second electric push rod 111; the telescopic parts of the two second electric push rods 111 are each fixed with a hollow connecting box 112; the interior of the two hollow connecting boxes 112 are each equipped with two front and rear The third electric push rods 113 are symmetrically distributed; the telescopic parts of the two third electric push rods 113 are each fixedly connected to a connecting plate 114; the two front connecting plates 114 are each fixedly connected to a rotating shaft, and the two rear connecting plates 114 each have a rotating hole, and the two rotating shafts can be inserted into the rotating holes of the corresponding side connecting plates 114; each of the two rotating shafts is rotatably connected to a fixed wheel 115, and a sponge pad is provided on the outside of the fixed wheel 115. The soft sponge pad can reduce the wear on the flange 001 when it comes into contact with the flange 001.

[0040] The fixing operation of the flange 001 of the present invention is specifically as follows:

[0041] like Figure 1-7 As shown, in order to make the flange 001 have enough space to be placed, all the telescopic parts of the first electric push rods 4 are controlled to retract, thereby driving the rotating wheels 5 on the corresponding side to retract, so that the fixed space formed by the four rotating wheels 5 becomes larger; then, the operator places the flange 001 in the fixed space formed by the four rotating wheels 5, and then controls all the telescopic parts of the first electric push rods 4 to push outward, thereby driving the rotating wheels 5 on the corresponding side to contact and fix the flange 001, as shown in FIG. Figure 3As shown, as the rotating wheel 5 is pushed out more, the rotating wheel 5 fixes the flange 001 more stably.

[0042] At this time, the flange 001 can be turned through the turning system. During this process, the driving motor set by the rotating wheel 5 can drive the rotating wheel 5 to rotate, and the rotating rotating wheel 5 drives the flange 001 to rotate, thereby completing the turning work of the flange 001; at the same time, the telescopic part of the first electric push rod 4 can be controlled to drive the rotating wheel 5 to be adaptively pushed out as the turning work progresses, so as to ensure that the flange 001 is sufficiently stable during turning.

[0043] After completing the turning work on the side opposite to the turning system of the flange 001, when it is necessary to turn the other side of the flange 001, the existing methods are generally as follows: 1. removing the flange 001 from the fixing device, adjusting the direction of the flange 001, and then placing it on the fixing device; 2. adjusting the position of the turning device; in this way, no matter which method is used, the turning position needs to be recalibrated after the adjustment, and the disassembly, adjustment and calibration operations are quite cumbersome, and the turning efficiency of the flange 001 still cannot be effectively improved.

[0044] In order to facilitate the adjustment of the flange 001, avoid tedious disassembly, adjustment and calibration operations, and enhance the stability of the flange 001; before the flange 001 is fixed, the two third electric push rods 113 on the same hollow connection box 112 are controlled to move the connecting plates 114 on the corresponding sides in opposite directions, so that the connecting plates 114 and the fixing wheels 115 are connected by the third electric push rods 113 on the same hollow connection box 112. Figure 6 The merged state shown changes to Figure 7 As shown in the open state, the flange 001 can be placed between two adjacent connecting plates 114, and then the connecting plates 114 and the fixed wheel 115 are connected by Figure 7 The open state shown changes to Figure 6 The combined state shown makes the rotating shafts on the two front connecting plates 114 inserted into the rotating holes of the corresponding side connecting plates 114 at the rear. Subsequently, the hollow connecting box 112 and its connecting parts are driven to move in opposite directions by the telescopic parts of the two second electric push rods 111, and a pulling force is applied to the flange 001 by the two fixed wheels 115 to realize the fixing operation of the fixed wheel 115 on the flange 001. In this way, the telescopic part of the above-mentioned first electric push rod 4 drives the rotating wheel 5 to be adaptively pushed out as the turning work progresses, which will be more stable.

[0045] Subsequently, the above-mentioned fixing operation of the rotating wheel 5 is performed, so that the inner and outer annular surfaces of the flange 001 are fixed, ensuring that the flange 001 has higher stability during the turning operation.

[0046] After completing the turning work on the opposite side of the flange 001 and the turning system, when it is necessary to turn the other side of the flange 001, first control the rotating wheel 5 to retract and stop the fixing operation on the outer ring surface of the flange 001, and then control the output part of the electric turntable 116 to drive the second electric push rod 111 and its connecting parts to rotate 180 degrees, so that the connecting plate 114 and the fixed wheel 115 drive the flange 001 to rotate 180 degrees. In this way, the adjustment and steering purpose of the flange 001 is achieved without performing disassembly and assembly operations, and the other side of the flange 001 can be turned, avoiding tedious disassembly, adjustment, and proofreading operations, and effectively improving the turning efficiency of the flange 001. Example 2

[0047] Based on the above embodiments, Figure 1-3 、 Figure 9 As shown, the turning system includes a robot arm 101 and a turning tool 102; the robot arm 101 is installed in front of the workbench 1; the turning tool 102 is bolted to the working part of the robot arm 101, and the flange 001 is turned by the turning tool 102.

[0048] like Figure 1-2 As shown, the mounting plate 2, the fixing ring 3, the first electric push rod 4, the rotating wheel 5 and the auxiliary fixing assembly are provided in two groups, and are symmetrical front to back; the turning tool 102 is a double-headed turning tool 102 structure; the turning tool 102 is used to simultaneously perform turning work on two flanges 001, which improves work efficiency while solving the problem of the existing turning method in which the turning tool 102 is used to perform turning work on only one flange 001, and only the turning point of the turning tool 102 is subjected to force, and the reverse direction is extremely unstable, which makes the turning tool 102 unbalanced as a whole, affects the turning accuracy of the flange 001, and reduces the durability of the turning tool 102.

[0049] The drive assembly includes a guide rail 6; the workbench 1 is installed with the guide rail 6; the guide rail 6 is slidably connected to two sliders that slide in the front and rear directions; the guide rail 6 is connected to the mounting plate 2 through the sliders; the mounting plate 2 and its connecting parts are driven to move back and forth on the guide rail 6 through the sliders.

[0050] The present invention performs the following operations for simultaneously turning two flanges 001:

[0051] like Figure 1-3 As shown, the working part of the robot arm 101 is controlled to drive the turning tool 102 to move between the two flanges 001, so that the two turning parts of the turning tool 102 are aligned with the parts to be turned of the flanges 001 on their corresponding sides. Subsequently, the two flanges 001 are turned simultaneously by the turning tool 102, completing the turning work of the facing surfaces of the two flanges 001;

[0052] Since the two flanges 001 need to be turned at the same time, in order to ensure that the turning tool 102 has high stability during the turning operation, the turning portion of the turning tool 102 needs to be as short as possible. Therefore, the two flanges 001 are relatively close to each other. When the two flanges 001 are adjusted and turned, the two turned flanges 001 will collide with each other. At this time, the slider on the control guide rail 6 drives the mounting plate 2 and its connecting parts to move back and forth on the guide rail 6, such as Figure 14 As shown, the distance between the two flanges 001 is enlarged, and then the flanges 001 are controlled to adjust and turn, which ensures that the turning part of the turning tool 102 is short and the device is small in size, and also avoids the problem of collision when the two flanges 001 are adjusted and turned. Example 3

[0053] Based on the above embodiments, Figure 9 As shown, the working part of the robot arm 101 is bolted to a baffle 103, and the baffle 103 is located outside the turning tool 102, and can cover the turning range of the turning tool 102; the baffle 103 is "U"-shaped, and the "U"-shaped baffle 103 can better cover the turning range of the turning tool 102.

[0054] like Figure 10-14 As shown, a chip cleaning system is also included; the chip cleaning system includes a fixed frame 201, a chip storage ring 202, a scraper ring 203, a scraper block 204 and a rotating assembly; the workbench 1 is equipped with a fixed frame 201, and the fixed frame 201 is located between the two fixed rings 3; the fixed frame 201 is fixedly connected to the chip storage ring 202, and the chip storage ring 202 is fixedly connected to the front fixed ring 3; the chip storage ring 202 is provided with a chip storage portion 202a, and the chip storage portion 202a collects the chips generated by the turning work; the rear fixed ring 3 is rotatably connected to the scraper Ring 203; a plurality of scraper blocks 204 distributed in a circular array are provided on the front side of the scraper ring 203, and the scraper blocks 204 are in contact with the chip storage portion 202a, and the scraper blocks 204 are used to scrape off the debris accumulated on the chip storage portion 202a; the workbench 1 and the scraper ring 203 are commonly connected with a rotating component, and the rotating component is used to drive the scraper ring 203 and the scraper blocks 204 to rotate; the scraper ring 203 and the scraper blocks 204 are driven to rotate by the rotating component, and the rotating scraper blocks 204 scrape off the debris accumulated on the chip storage portion 202a.

[0055] The rotating assembly includes a power motor 211 , a gear 212 and a gear ring 213 ; the workbench 1 is equipped with the power motor 211 ; the output shaft of the power motor 211 is fixedly connected to the gear 212 ; the outside of the scraper ring 203 is fixedly connected to the gear ring 213 , and the gear ring 213 is meshed with the gear 212 .

[0056] It also includes a mounting frame 205, a connecting roller 206 and a scraper plate 207; the mounting frame 205 is installed on the right side of the fixed frame 201; the mounting frame 205 is slidably connected to the connecting roller 206 which slides up and down, and the connecting roller 206 is connected to the mounting frame 205 by a spring; the connecting roller 206 is rotatably connected to the scraper plate 207, and the scraper plate 207 is connected to the connecting roller 206 by a torsion spring, and the scraper plate 207 is scraped off by the scraper plate 207 to scrape off the debris attached to the side of the scraper block 204 facing the scraper plate 207.

[0057] The two fixing rings 3 are bolted together with the scraper strip 208, which scrapes away the debris attached to the surface of the scraper block 204 facing the center of the scraper ring 203.

[0058] The chip processing work of flange turning of the present invention is specifically as follows:

[0059] During the process of the turning tool 102 turning the two flanges 001, the "U"-shaped baffle 103 can wrap the range of the turning tool 102, so that the debris of the flange 001 turned by the turning tool 102 is gathered in the baffle 103. When there is excessive debris in the baffle 103, the debris will naturally fall down onto the chip storage part 202a. Then, the output shaft of the power motor 211 is controlled to drive the gear 212 to rotate, so that the gear 212 drives the gear ring 213, the scraper ring 203 and the scraper block 204 to rotate counterclockwise from the front to the back; the rotating scraper block 204 scrapes the debris on the chip storage part 202a to the right along the arc surface of the chip storage part 202a, so that it is scraped out at the mounting frame 205 and collected by an external debris collection device to ensure the working environment of the operation workshop.

[0060] It should be noted that when the scraper block 204 contacts the debris on the scraper storage portion 202a, the side thereof facing the scraper plate 207 is bound to be stained with the debris; for this reason, when the scraper block 204 rotates, it is constantly in contact with the scraper plate 207. Since the scraper plate 207 is connected to the connecting roller 206 by a torsion spring, the torsion force of the torsion spring presses the scraper plate 207 toward the scraper block 204. When the scraper block 204 rotates past, the debris on the side of the scraper block 204 facing the scraper plate 207 is scraped off by the scraper plate 207; since the connecting roller 206 can slide up and down in the mounting frame 205, and the connecting roller 206 is rotatably connected to the scraper plate 207, when the scraper block 204 rotates past, the scraper plate 207 and the connecting roller 206 can adaptively move down and rotate without getting stuck, so that the debris attached to the scraper block 204 can be cleaned and collected.

[0061] After a scraper block 204 passes by, the scraper plate 207 and the connecting roller 206 are naturally restored to their initial state by the spring connected thereto, so that when the next scraper block 204 passes by, the debris on it can be scraped off.

[0062] At the same time, when the scraper block 204 rotates and passes the scraper bar 208, the scraper block 204 facing the center of the scraper ring 203 continuously scrapes the scraper bar 208, so that the scraper bar 208 scrapes off the debris attached to the scraper block 204 facing the center of the scraper ring 203, thereby facilitating the cleaning and collection of the debris on the scraper block 204. Example 4

[0063] Based on the above embodiments, Figure 6-8 As shown, a real-time measurement system is also included; the real-time measurement system includes an expansion block 301 and an inner diameter measurement component; an expansion block 301 is provided on the facing surfaces of each two adjacent connecting plates 114, and the expansion block 301 is provided with a detection chip; the expansion block 301 is externally connected to an air pump, and the turning thickness of the flange 001 is detected in real time through the expansion block 301; the two frontmost connecting plates 114 and the two rearmost connecting plates 114 are commonly connected to the inner diameter measurement component.

[0064] The inner diameter measuring assembly includes a mounting block 302 and a scale 303; the two frontmost connecting plates 114 and the two rearmost connecting plates 114 are each bolted to a mounting block 302; the two front mounting blocks 302 are slidably connected to a scale 303, and the two rear mounting blocks 302 are slidably connected to another scale 303.

[0065] The real-time measurement work of the present invention is specifically as follows:

[0066] like Figure 5-6 、 Figure 8 As shown, after the turning tool 102 turns the front and rear sides of the flange 001, its overall thickness is bound to decrease. For this reason, the external air pump is controlled to inject gas into the two expansion blocks 301, so that the two expansion blocks 301 expand toward each other and fit tightly against the flange 001. The detection chips provided in the two expansion blocks 301 can detect the thickness of the flange 001 in real time as the turning work progresses, realizing non-stop measurement and solving the problem of the existing method that the turning work needs to be frequently stopped for measurement during the turning work.

[0067] When the inner annular surface of the flange 001 is turned, as the turning work proceeds, the inner diameter of the flange 001 also increases, so that the telescopic part of the second electric push rod 111 drives the connecting plate 114 and the fixed wheel 115 to gradually shrink to adapt to the inner diameter of the flange 001. As the distance between the two mounting blocks 302 increases, more of the scale 303 is exposed. In this way, the inner diameter data of the flange 001 can be obtained according to the scale exposed by the scale 303, realizing non-stop detection, and solving the problem of the existing method that the turning work needs to be frequently stopped for measurement during the turning work.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
