Abstract
Description
Technical Field
[0001] This application relates to the field of welded pipe welding technology, and in particular to a positioning device for welded pipe production and processing. Background Technology
[0002] Welded pipes are steel pipes made by rolling steel strips or plates into a tubular shape and then welding the seams together. They are widely used in oil and gas transportation, building structures, and machinery manufacturing. Compared to seamless steel pipes, welded pipes are lighter in weight while maintaining the same strength, and can be produced in large diameters with thin walls. Currently, welded pipe production is developing towards automation and intelligence, and precise positioning is a key step in ensuring welding quality and production efficiency during the production process.
[0003] The existing technology still has the following problems:
[0004] 1. Existing positioning devices cannot accurately detect whether the positioning is accurate during the welding process. Under long-term use, the equipment is subjected to the pressure of welding pipes, which can easily cause wear and deformation, causing the originally calibrated positioning benchmark to shift. This leads to the gradual accumulation of errors in the center positioning and weld alignment of the welded pipe. In addition, the positioning device lacks an early warning mechanism and cannot be corrected and maintained in real time. As a result, the longer the equipment is used, the higher the welding defect rate of the welded pipe, increasing the pressure of subsequent maintenance.
[0005] 2. Existing positioning devices cannot collect welding debris. If the metal debris generated during the welding process is not dealt with in time, it will easily adhere to the outer surface of the positioning equipment. After cooling, it will form hard weld slag deposits, which will damage the flatness of the positioning reference and affect the welding accuracy. In addition, debris that is not cleaned in time will easily accumulate inside the equipment, reducing the service life of the equipment. Summary of the Invention
[0006] To overcome the shortcomings of existing positioning devices, which cannot accurately detect positioning during the welding process, and which, under prolonged use, are prone to wear and deformation due to the pressure exerted during pipe welding, causing the originally calibrated positioning benchmark to shift, resulting in the gradual accumulation of errors in the center positioning and weld alignment of subsequent welded pipes. Furthermore, the lack of an early warning mechanism prevents real-time correction and maintenance, leading to a higher defect rate in pipe welding over longer service life and increased maintenance pressure. Existing positioning devices also cannot collect welding debris; if not promptly handled, the metal debris easily adheres to the outer surface of the positioning device, forming hard weld slag deposits upon cooling, damaging the flatness of the positioning benchmark and affecting welding accuracy.

[0017] The technical solution provided in this application has at least the following technical effects or advantages:
[0018] 1. By employing a positioning component, this invention effectively solves the problem that existing positioning devices cannot accurately detect positioning during the welding process. Furthermore, prolonged use exposes the equipment to the pressure exerted during pipe welding, leading to wear and deformation that causes the originally calibrated positioning reference to shift. This results in a gradual accumulation of errors in the subsequent positioning of the pipe's center and weld alignment. In addition, the positioning device lacks an early warning mechanism, making real-time correction and maintenance impossible. Consequently, the longer the equipment is used, the higher the defect rate in pipe welding, increasing subsequent maintenance pressure. This invention, through its positioning component, can perform positioning detection on the positioning device during the welding process, ensuring accurate positioning of the pipe even after prolonged use. Moreover, it can promptly issue an alarm when the positioning device shifts or deforms, enabling rapid maintenance by staff, reducing the defect rate in pipe welding, and decreasing subsequent maintenance pressure.
[0019] 2. By employing a dust collection component, the problem of existing positioning devices being unable to collect welding debris is effectively solved. If metal debris generated during pipe welding is not treated promptly, it easily adheres to the outer surface of the positioning equipment, forming hard weld slag deposits after cooling. This damages the flatness of the positioning reference and affects welding accuracy. Furthermore, debris that is not cleaned in time tends to accumulate inside the equipment, reducing its lifespan. This invention, through its dust collection component, can collect debris generated during pipe welding, preventing welding debris from splashing and adhering to the outer surface of the equipment, preventing damage to the flatness of the positioning reference, improving the welding accuracy of the pipe, and enabling real-time debris processing to avoid debris accumulation and damage to the equipment, thereby extending its lifespan.

Detailed Implementation
[0034] Since the positioning device cannot accurately detect whether the positioning is accurate during the welding process, the present invention can detect the positioning of the positioning device during the welding process through the positioning component, so that the welded pipe can still maintain accurate positioning after long-term use; since the positioning device cannot collect the welding debris, the present invention can collect the welding debris during the welding of the welded pipe through the dust collection component, preventing the welding debris from splashing and adhering to the outer surface of the equipment.
[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1:
[0036] Please see Figure 1 and Figure 2As shown, a positioning device for welded pipe production and processing includes a base 1, a first motor 2, and a cylinder 4. The first motor 2 is mounted on the outer surface of the base 1, and its output end is connected to a second threaded rod. A piston rod is slidably connected to the inner cavity of the cylinder 4. A movable frame 3 is slidably connected to the outer surface of the base 1, and the cylinder 4 is fixedly mounted on the outer surface of the movable frame 3. A positioning component 5 is mounted on the outer surface of the base 1, and a fixed platform 6 is fixedly mounted on the outer surface of the base 1. Both the positioning component 5 and the fixed platform 6 have clamping mechanisms 7 on their outer surfaces. The inner cavity of the clamping mechanism 7 clamps a pipe fitting 8. A dust collection component 9 is mounted on the outer surface of the fixed platform 6, and an insertion rod 10 is mounted on the outer surface of the dust collection component 9. When welding the pipe fitting 8, the two pipe fittings 8 to be welded are clamped and fixed by the clamping mechanism 7. The operation of the first motor 2 drives the second threaded rod to rotate, causing the positioning component 5 to slide on the outer surface of the base 1, thereby making the ends of the two pipe fittings 8 come into close contact and weld. The cylinder 4 is used to detect whether the positioning component 5 has moved into place, thereby ensuring the accurate positioning of the positioning component 5. The fixed table 6 is used to support one of the clamping mechanisms 7. The positioning component 5 can adjust the height and angle of the other clamping mechanism 7 to ensure that the two pipe fittings 8 can be accurately connected. At the same time, the insertion rod 10 and the positioning component 5 can detect whether the positioning component 5 and the fixed table 6 are accurately positioned, thereby avoiding unevenness during the welding of the pipe fittings 8. The dust collection component 9 is used to collect the debris generated during welding and can prevent the debris from accumulating and avoiding secondary stirring and contamination of the equipment.
[0037] Please see Figure 2 and Figure 3As shown, the positioning component 5 includes a movable plate 51, a first slider 52 fixedly mounted at the bottom end of the movable plate 51, a positioning mechanism 53 provided in the middle part of the movable plate 51, and adjustment mechanisms 54 provided on both sides of the movable plate 51. A support plate 55 is provided on the outer surface of the adjustment mechanism 54, and a connecting block 56 is fixedly mounted on one end of the support plate 55. A horizontal detection mechanism 57 and an anti-deviation mechanism 58 are provided in the inner cavity of the connecting block 56. A positioning wheel 59 is rotatably connected to one end of the piston rod. A scale line is provided on the outer surface of the base 1, and a second pointer is provided on the outer surface of the movable frame 3, pointing to the scale line. The first slider 52 and the base 1 are slidably connected, and the first slider 52 and the second threaded rod are connected by threads. The movable plate 51 and the base 1 are slidably connected. The adjustment mechanisms 54 are symmetrically distributed about the middle part of the movable plate 51. During the welding process, the movable frame 3 is moved to the middle position that the positioning component 5 needs to move, and the movement distance of the movable frame 3 is observed by the second pointer on the first motor 2. The cylinder 4 performs positioning detection on the positioning component 5, that is, the two pipe fittings 8 to be welded are clamped on the two clamping mechanisms 7. At this time, the operation of the first motor 2 drives the second threaded rod to rotate. The first motor 2 can be a stepper motor to ensure the accuracy of the movement of the moving plate 51, so that the first slider 52 slides in the inner cavity of the base 1 and drives the moving plate 51 to slide on the base 1, so that the two ends of the pipe fittings 8 are in close contact. At the same time, the working piston rod of the cylinder 4 moves, and the movement of the piston rod drives the positioning wheel 59 to squeeze the positioning mechanism 53, which is used to check whether the moving plate 51 has moved into place. The adjustment mechanism 54 is used to adjust the height and angle of the support plate 55, so that the upper surface of the support plate 55 and the fixed platform 6 are kept flush. The horizontal detection mechanism 57 on the connecting block 56 is used to determine whether the support plate 55 and the fixed platform 6 are kept parallel, that is, to determine whether the pipe fittings 8 are tilted. The anti-offset mechanism 58 is used to detect whether the support plate 55 and the fixed platform 6 are offset, and to issue an alarm when offset occurs.
[0038] Please see Figure 4 and Figure 5As shown, the positioning mechanism 53 includes a positioning block 531. A positioning groove 532 is formed on the outer surface of the positioning block 531. The positioning block 531 and the moving plate 51 are slidably connected. A floating block 533 is fixedly installed on the outer surface of the positioning block 531. The floating block 533 and the moving plate 51 are slidably connected. Slide rods 534 are fixedly installed on both sides of the floating block 533. The slide rods 534 and the moving plate 51 are slidably connected. A first spring 535 is sleeved on the outer surface of the slide rods 534. The first spring 535 is located between the floating block 533 and the inner wall of the moving plate 51. A first fixing block 536 is fixedly installed on the outer surface of the moving plate 51. A first button 537 is provided in the inner cavity of the floating block 533. There are two first buttons 537, which are positioned relative to the first fixing block 536. The floating blocks 533 are symmetrically distributed. A first alarm 538 is fixedly installed on the outer surface of the floating blocks 533. A first button 537 is electrically connected to the first alarm 538, and pressing the first button 537 controls the first alarm 538 to sound an alarm. There is a gap between the first fixed block 536 and the first button 537. The adjusting mechanism 54 includes a connecting seat 541, which is fixedly connected to a moving plate 51. A first connecting strip 542 is rotatably connected to the inner cavity of the connecting seat 541. A second connecting strip 543 is rotatably connected to the end of the first connecting strip 542 away from the connecting seat 541. An adjusting seat 544 is fixedly installed on the outer surface of the moving plate 51. A second slider 545 is slidably connected to the inner cavity of the adjusting seat 544. The two ends of the second slider 545 are connected to the second connecting strip 543. The second connecting strip 543 is rotatably connected to the inner cavity of the adjusting seat 544, and the second slider 545 is rotatably connected to the first threaded rod 546. An adjusting block 547 is provided at the end of the second connecting strip 543 away from the second slider 545. A rotating rod is provided in the inner cavity of the adjusting block 547, and the rotating rod is rotatably connected to the second connecting strip 543. The adjusting blocks 547 are located on the lower surfaces of both ends of the support plate 55, and one of the adjusting blocks 547 has a groove in its inner cavity. The rotating rod and the groove are slidably connected, allowing the rotating rod to slide or rotate within the groove. This facilitates adjustment of the angle of the support plate 55, ensuring that the outer surfaces of the support plate 55 and the fixed platform 6 remain flush during long-term use. The moving plate 5... 1. After moving to the designated position, the piston rod moves due to the operation of cylinder 4. The movement of the piston rod causes the positioning wheel 59 to approach the positioning groove 532. When the overall movement distance of the moving plate 51 does not meet the requirements, the positioning wheel 59 presses against the side of the positioning groove 532. At this time, the pressing of the positioning wheel 59 causes the positioning block 531 to slide on the outer surface of the moving plate 51. The sliding of the positioning block 531 causes the floating block 533 to slide in the inner cavity of the moving plate 51. At the same time, the sliding rod 534 slides in the inner cavity of the moving plate 51 and presses against the first spring 535. At this time, the first fixed block 536 presses against the first button 537, causing the first alarm 538 to sound an alarm, reminding the staff that the positioning of the positioning component 5 is not accurate enough and needs to be adjusted.When the positioning component 5 moves to the specified position, the positioning wheel 59 and the positioning groove 532 engage at the middle. When the displacement of the moving plate 51 is adjusted, the position of the moving frame 3 on the base 1 can be adjusted, making it easier for the positioning wheel 59 to position and detect the moving plate 51. The adjustment mechanism 54 is used to adjust the height and angle of the support plate 55. By rotating the first threaded rod 546, the second slider 545 slides in the inner cavity of the adjustment seat 544. At this time, the movement of the second slider 545 drives the second connecting bar 543 to rotate. The rotation of the second connecting bar 543 drives the first connecting bar 542 to rotate in the inner cavity of the connecting seat 541, thereby changing the height of the adjustment block 547. When both first threaded rods 546 are rotated simultaneously, the height of the support plate 55 can be changed. When one first threaded rod 546 is rotated, the angle of the support plate 55 can be adjusted, so that the outer surface of the support plate 55 and the fixed platform 6 always remain flush, improving the welding accuracy of the pipe fitting 8.
[0039] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the horizontal detection mechanism 57 includes a detection block 571. A buffer rod 572 is fixedly connected to the outer surface of the detection block 571. A second spring 573 is sleeved on the outer surface of the buffer rod 572. An elastic block 574 is slidably connected to the inner cavity of the detection block 571. A third spring 575 is sleeved on one end of the elastic block 574. The third spring 575 is located between the inner walls of the elastic block 574 and the buffer rod 572. A first compression wheel 576 is rotatably connected to the end of the elastic block 574 away from the third spring 575. A balance block 577 is rotatably connected to the inner cavity of the detection block 571. A first pointer 578 is fixedly installed on the outer surface of the balance block 577. A scale line is opened on the outer surface of the detection block 571. The first pointer 578 points to the scale line. A balance adjustment 579 is fixedly installed on the outer surface. Connecting rods 5710 are rotatably connected to both ends of the balance adjustment 579. Balance blocks 577 are symmetrically distributed about the first compression wheel 576. A buffer rod 572 is slidably connected to the connecting block 56. A second spring 573 is located between the detection block 571 and the connecting block 56. When the moving plate 51 approaches the fixed platform 6, the connecting rod 5710 and the outer surface of the fixed platform 6 are in close contact. The anti-deviation mechanism 58 includes a detection rod 581. A slot 582 is provided at one end of the detection rod 581. A fixing ring 583 is fixedly installed on the outer surface of the detection rod 581. A second fixing block 584 is fixedly installed on the outer surface of the connecting block 56. A second alarm 585 is fixedly installed on the outer surface of the second fixing block 584. The outer surface of the second alarm 585 is provided with a second button 586. A storage rod 587 is fixedly installed on the outer surface of the second fixing block 584. A telescopic block 588 is slidably connected to the inner cavity of the storage rod 587. A retaining ball 589 is movably connected to the end of the telescopic block 588 away from the storage rod 587. A fourth spring 5810 is provided in the inner cavity of the storage rod 587. An adjusting rod 5811 is threadedly connected to the inner cavity of the telescopic block 588, which can be used to adjust the distance between the adjusting rod 5811 and the second button 586, thereby controlling the alarm spacing. The inner cavities of the fixing ring 583 and the connecting block 56 are slidably connected. A groove is provided at the end of the detection rod 581 away from the slot 582, and the retaining ball 589 engages with the groove. The second alarm 585 is electrically connected to the second button 586, and the second button... Pressing button 586 activates the second alarm 585, aligning the second button 586 with the adjusting rod 5811. The fourth spring 5810 is located between the second fixed block 584 and the telescopic block 588. When the moving plate 51 approaches the fixed platform 6, the insert rod 10 and the inner cavity of the detection rod 581 are engaged. During the welding of the two pipe fittings 8, the moving plate 51 approaches the fixed platform 6, causing the horizontal detection mechanism 57 on the connecting block 56 to contact the outer surface of the fixed platform 6. That is, the connecting rod 5710 contacts the outer surface of the fixed platform 6 and compresses the balance adjustment 579. At this time, the buffer rod 572 slides in the inner cavity of the connecting block 56 and compresses the second spring 573. The elastic force of the second spring 573 is used to buffer the impact generated during the contact process.Simultaneously, it ensures close contact between the connecting rod 5710 and the outer surface of the fixed platform 6. When the upper surface of the support plate 55 and the fixed platform 6 tilts, the fixed platform 6 exerts pressure on the connecting rod 5710, causing the balance adjuster 579 to tilt. The tilting of the balance adjuster 579 causes the balance block 577 to rotate within the inner cavity of the detection block 571. The rotation of the balance block 577 causes it to press against the first compression wheel 576, causing the elastic block 574 to slide within the inner cavity of the detection block 571 and press against the third spring 575. The third spring 575 is used to keep the first compression wheel 576 and the balance block 577 tightly connected. The close contact ensures that the balance block 577 remains balanced under no external force. However, when the fixed platform 6 and the support plate 55 tilt relative to each other, the balance block 577 rotates under external force, causing the angle of the first pointer 578 to deflect. That is, the scale line pointed to by the first pointer 578 changes, which allows for a more intuitive judgment that the support plate 55 is tilted relative to the outer surface of the fixed platform 6. This makes it impossible to guarantee that the pipe fittings 8 to be welded remain flush. In addition, when the moving plate 51 approaches the fixed platform 6, the inner cavities of the insertion rod 10 and the detection rod 581 engage to determine whether there is a positional deviation when the two pipe fittings 8 are connected. When a positional deviation occurs, the insertion rod 10 presses against the recessed area on the slot 582 side of the detection rod 581, causing the fixing ring 583 to shift within the inner cavity of the connecting block 56. This shift in the fixing ring 583 causes the detection rod 581 to shift, and the shift in the detection rod 581 causes its groove to press against the retaining ball 589. This causes the telescopic block 588 to slide within the inner cavity of the storage rod 587 and press against the fourth spring 5810. Simultaneously, the sliding of the telescopic block 588 causes the adjusting rod 5811 to press against the second button 586, triggering the second alarm 585 on the second fixing block 584 to sound. An alarm is triggered to alert staff that there is a deviation between the positioning component 5 and the fixed platform 6, indicating that the positioning of the two pipe fittings 8 is not precise enough. The positioning mechanism 53 detects whether the positioning of the moving plate 51 near the fixed platform 6 is accurate, the horizontal detection mechanism 57 detects whether the support plate 55 and the fixed platform 6 are tilted, and the anti-offset mechanism 58 determines whether there is an offset between the fixed platform 6 and the positioning component 5. The second alarm 585 and the first alarm 538 have different alarm sounds to facilitate identification of the problem and rapid maintenance, reducing the defect rate of the pipe fittings 8 welding and reducing subsequent maintenance pressure. Example 2:
[0040] Please see Figure 1 and Figure 11As shown, the clamping mechanism 7 includes a first connecting plate 71, a second motor 72 on the outer surface of the first connecting plate 71, a third threaded rod rotatably connected to the inner cavity of the first connecting plate 71, the output end of the second motor 72 and the third threaded rod being sleeved together, clamping arms 73 slidably connected to both sides of the first connecting plate 71, the clamping arms 73 and the third threaded rod being threaded together, and the two ends of the third threaded rod having opposite thread directions, clamping blocks 74 being fixedly installed at both ends of the clamping arms 73, and the pipe fitting 8 being clamped and fixed in the inner cavity of the clamping blocks 74. There are two clamping mechanisms 7, one of which is fixedly connected to the upper surface of the fixed platform 6, and the other is fixedly connected to the upper surface of the support plate 55. The operation of the second motor 72 drives the third threaded rod to rotate, thereby driving the clamping arm 73 to slide on the outer surface of the first connecting plate 71, so that the clamping blocks 74 clamp and fix the pipe fitting 8, which facilitates the welding of the pipe fitting 8.
[0041] Please see Figure 8 and Figure 9As shown, the dust collection assembly 9 includes a collection box 91, with baffles 92 fixedly installed on both sides of the collection box 91. A limit rod 93 is fixedly installed on the inner wall of the collection box 91. A floating frame 94 is slidably connected to the inner cavity of the collection box 91. Dust-blocking strips 95 are evenly arranged on the inner wall of the floating frame 94, with rounded upper ends to facilitate debris falling into the inner cavity of the collection box 91. A pull-out long plate can be opened on the bottom side of the collection box 91 to facilitate the collection of debris from the inner wall of the collection box 91. A shaking mechanism 96 is provided on both sides of the collection box 91, along with a rod 10 and... The outer surface of the collection box 91 is fixedly connected to the shaking mechanism 96, which includes a connecting frame 961. The connecting frame 961 is fixedly connected to the lower surface of the support plate 55. A second extrusion wheel 962 is rotatably connected to the end of the connecting frame 961 away from the support plate 55. A second connecting plate 963 is slidably connected to the outer surface of the limiting rod 93. The second connecting plate 963 is fixedly connected to the floating frame 94, and the second connecting plate 963 is slidably connected to the collection box 91. A protrusion 964 is fixedly installed on the lower surface of the second connecting plate 963. The top end of the second extrusion wheel 962 is located at the second... The lower surface of the connecting plate 963 is attached to and higher than the bottom end of the protrusion 964, moving the junction of the pipe 8 directly above the collection box 91. During welding of the pipe 8 connection, the baffle plate 92 blocks the generated debris, causing it to fall into the collection box 91. The dust baffle 95 on the floating frame 94 further blocks the debris, preventing it from being stirred up and causing secondary pollution. The shaking mechanism 96 shakes the accumulated debris from the dust baffle 95 between the collection box 91 and the dust baffle 95. That is, during the movement of the positioning component 5, the support... The support plate 55 moves, which in turn moves the connecting frame 961. The movement of the connecting frame 961 causes the second extrusion wheel 962 to extrude pressure on the protrusion 964, causing the second connecting plate 963 to slide on the outer surface of the limiting rod 93. The sliding of the second connecting plate 963 causes the floating frame 94 to slide in the inner cavity of the collection box 91. Thus, when the support plate 55 moves, the second extrusion wheel 962 continuously drives the floating frame 94 to vibrate in the inner cavity of the collection box 91, so that the debris on the dust baffle 95 falls into the bottom of the collection box 91 as soon as possible for centralized collection.
[0042] In summary, when welding pipe fittings 8, the two pipe fittings 8 to be welded are clamped and fixed by clamping mechanism 7. At this time, the operation of the first motor 2 drives the second threaded rod to rotate, causing the positioning component 5 to slide on the outer surface of the base 1, thereby making the ends of the two pipe fittings 8 come into close contact and weld. Cylinder 4 is used to detect whether the positioning component 5 has moved into place, thereby ensuring the accurate positioning of the positioning component 5. The fixing table 6 is used to support one of the clamping mechanisms 7. The positioning component 5 can adjust the height and angle of the other clamping mechanism 7 to ensure that the two pipe fittings 8 can be accurately connected. At the same time, the insertion rod 10 and the positioning component... The 5-clamping mechanism can detect whether the positioning component 5 and the fixed platform 6 are accurately positioned, thereby avoiding unevenness during the welding of the pipe fitting 8. The dust collection component 9 is used to collect the debris generated during welding and can prevent the debris from accumulating and being stirred up again to contaminate the equipment. The operation of the first motor 2 drives the second threaded rod to rotate. The first motor 2 can be a stepper motor to ensure the accuracy of the movement of the moving plate 51, so that the first slider 52 slides in the inner cavity of the base 1 and drives the moving plate 51 to slide on the base 1, so that the two ends of the pipe fitting 8 are in close contact. At the same time, the working piston rod of the cylinder 4 moves, and the movement of the piston rod drives the... The moving positioning wheel 59 presses against the positioning mechanism 53 to check whether the moving plate 51 has moved into place. The adjusting mechanism 54 is used to adjust the height and angle of the support plate 55 to ensure that the upper surface of the support plate 55 and the fixed platform 6 are flush. The horizontal detection mechanism 57 on the connecting block 56 is used to determine whether the support plate 55 and the fixed platform 6 are parallel, that is, to determine whether the pipe 8 is tilted. The anti-deviation mechanism 58 is used to detect whether the support plate 55 and the fixed platform 6 are deviated and to issue an alarm when deviation occurs. There are two clamping mechanisms 7, one of which is fixedly connected to the upper surface of the fixed platform 6, and the other is fixed to the upper surface of the support plate 55. The pipe fitting 8 is fixedly connected to the surface. The operation of the second motor 72 drives the third threaded rod to rotate, thereby causing the clamping arm 73 to slide on the outer surface of the first connecting plate 71, so that the clamping block 74 clamps and fixes the pipe fitting 8, and moves the junction of the pipe fitting 8 to the top of the collection box 91. When welding the connection of the pipe fitting 8, the baffle plate 92 is used to block the generated debris, so that the debris falls into the collection box 91 and is blocked by the dust baffle strip 95 on the floating frame 94 to prevent the debris from being blown up and causing secondary pollution. The shaking mechanism 96 is used to shake the debris accumulated on the dust baffle strip 95 and collect it between the collection box 91 and the dust baffle strip 95.
