Description

Technical Field

[0001] This invention relates to the field of oven tube processing technology, specifically to an oven tube riveting processing device. Background Technology

[0002] During the processing of oven tubes, in order to ensure accurate matching and assembly with other components, the oven tubes need to be coiled and riveted to make their shape and size more regular, thereby improving production efficiency and product quality.

[0003] For example, the oven tube riveting equipment with announcement number CN216461287U uses riveting blocks and pushing blocks. Pipe clamps are placed at positions corresponding to the pushing blocks, and the upper and lower locking tabs of the pipe clamps align with the upper and lower rings of the oven tube. The first cylinder is then activated, using the pushing block to press the pipe clamps, thus riveting them onto the oven tube. This process facilitates the shaping of the oven tubes and makes them easier to use later. However, in actual use, when riveting oven tubes of different diameters, different sizes of fixing blocks must be used. Furthermore, the heat exchange area per unit volume directly affects the compactness and efficiency of the equipment due to the different pipe sizes. Adjusting the screw pitch allows for precise control of the heat exchange performance of pipes with different diameters. Therefore, the screw pitch varies between oven tubes of different diameters. To ensure the reliability of the riveted oven tubes, different sizes of pipe clamps are needed to fix them, and different sizes of pushing blocks must also be used. This makes it inconvenient to rivet oven tubes of different diameters and presents certain limitations in its use.

[0004] Therefore, we propose an oven tube riveting processing device to solve the problems mentioned above. Summary of the Invention

[0021] Preferably, a geared motor is fixedly installed at the top center of the workbench, and the output end of the geared motor passes through the workbench and is fixedly installed on a rotating plate. The top of the rotating plate is provided with three sliding grooves at equal intervals, and the bottom of the three movable seats is fixedly installed with a column block, and the column block is slidably connected to the sliding groove.

[0022] By adopting the above technical solution, the three movable seats can move simultaneously.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the oven tube riveting processing equipment enables the oven tube to be riveted adaptively according to the diameter of the oven tube when riveting and fixing it, and facilitates the fixing of tube clamps of different sizes, avoiding the need to change the riveting structure of different sizes, thus improving the overall application range. At the same time, after fixing oven tubes of different diameters, it is convenient to rivet pipes of different diameters when facing tube clamps of different sizes. After the oven tube is riveted and fixed, the fixing structure on the tube clamp can automatically loosen the tube clamp, without the need to disassemble the tube clamp again. The riveting strength of the oven tube can be tested after riveting, and any loosening of the oven tube riveting can be detected in time, thus improving the processing quality of the oven tube. 1. When riveting and positioning the oven tubes, the oven tubes are spirally coiled. The coiled oven tubes are supported and fixed using a fixing component. Then, during riveting, the oven tubes are placed inside the tube clamps, which position them. The geared motor is then activated to rotate the rotating plate. The rotation of the rotating plate, through the connection between the column block and the sliding groove, causes the three movable seats to move away simultaneously. This, in turn, moves the U-shaped frame via the support column. After the U-shaped frame moves, the arc-shaped plate abuts against the two coiled oven tubes. The U-shaped frame continues to move, allowing it to slide on the movable rod. During the movement of the U-shaped frame, the mounting plate can be moved by a steel wire rope. The mounting plate slides on the fixing rod and stretches the telescopic spring, causing the two positioning plates to approach and abut against the oven tube. This allows for further positioning of the oven tube. As the two positioning plates approach, the ball bearings on the L-shaped bracket abut against the slope of the tube clamp. This applies pressure to both ends of the tube clamp as the positioning plates move, causing the tube clamp to deform along the central fold. After deformation, the tube clamp can be riveted and positioned to hold the coiled oven tube in place. This allows for adaptive riveting of the oven tube according to its diameter and facilitates fixing tube clamps of different sizes, avoiding the need to replace riveting structures of different sizes and improving the overall usability. 2. When riveting the oven tubes, the movement of the U-shaped frame first causes the insert block to abut against the two oven tubes. As the U-shaped frame moves, the inclined sides of the insert block support the middle of the two oven tubes. After the insert block abuts, the U-shaped frame continues to move, causing it to slide on the sliding rod. As the U-shaped frame continues to move, it can drive the column rod to move via the support plate. During the movement of the column rod, the connecting rod rotates, thereby causing the mounting bracket to move closer to the movable rod, so that the rubber wheel abuts against the movable rod. Afterward, the U-shaped frame continues to move, and the connecting rod continues to rotate, causing the connecting plate to slide on the column rod and stretch the return spring. When the movable rod moves subsequently, it will drive the abutting rubber wheel to rotate counterclockwise. The ratchet can move the ratchet teeth. After the riveting is completed, the U-shaped frame returns to its original position. When the U-shaped frame returns to its original position, the insert block will not immediately leave. The oven tube and connecting rod will not rotate. If the movable rod resets, it will drive the ratchet to rotate clockwise. At this time, the ratchet prevents the rubber wheel from rotating. The rubber wheel and the movable rod are in close contact to position the movable rod, thus preventing the positioning plate from resetting. When the U-shaped frame resets and moves, the rubber pad on the positioning plate abuts against the oven tube. The U-shaped frame reset can apply tension to the riveted oven tube, allowing observation of whether the oven tube and the tube clamp have separated and deformed. As the U-shaped frame resets and moves further, the insert block separates from the oven tube, and then the rubber wheel resets under the support spring, no longer positioning the movable rod. The positioning plate can reset, allowing the riveting strength of the oven tube to be tested after riveting. If there is any looseness in the oven tube riveting, it can be detected in time, improving the processing quality of the oven tube. 3. When fixing the pipe clamp, move the two clamping plates away from each other, so that the positioning rod slides on the fixing block and the tension spring deforms. Then, place the pipe clamp inside the movable frame and release the clamping plates. Under the action of the tension spring, the two clamping plates come closer together to clamp and fix the pipe clamp. At the same time, the tension spring is in the stretched state, and the cone block is located in the middle fold of the pipe clamp. During the riveting process, the middle fold of the pipe clamp deforms and closes continuously. During the closing process, the fold of the pipe clamp can be pushed by the oblique side of the cone block to move, and then the clamping plate is driven away from the pipe clamp through the fixing plate. After the pipe clamp deforms during riveting, the fold closes, and the clamping plate is removed from the pipe clamp. Afterwards, it can be directly removed from the movable frame without disassembling the pipe clamp, which improves the convenience of operation. Attached Figure Description

[0027] Please see Figures 1-9 The present invention provides a technical solution: an oven tube riveting processing equipment, including a workbench 1 and a tube clamp 1011. Three support frames 101 are equidistantly installed on the top of the workbench 1, and electric push rods 102 are fixedly installed on the upper part of the interior of each of the three support frames 101. The tube clamp 1011 has a folded opening in the middle and slopes on both sides of the tube clamp 1011.

The three movable slots 103 are located inside the three support frames 101, and support rods 104 are symmetrically installed inside the three movable slots 103. Movable seats 105 are slidably connected to the outside of two support rods 104, and support columns 106 are fixedly installed on the top of the movable seats 105. Riveting assembly 2 is respectively set above the three support columns 106, and riveting assembly 2 includes U-shaped frame 201; U-shaped frame 201 is fixedly installed on the top of support column 106. A movable rod 202 is symmetrically slidably connected to one side of the inner side of the U-shaped frame 201. An arc plate 203 is fixedly installed at one end of each of the two movable rods 202, and an installation block 204 is fixedly installed at the other end of each of the two movable rods 202. Meanwhile, a connecting frame 205 is fixedly installed on one side of the installation block 204. The U-shaped frame 201 has symmetrical sliding connections of movable rods 206 on both sides inside. A positioning plate 2061 is fixedly installed on the end of the two movable rods 206 that is close to each other. A rubber pad is fixedly installed on the side of the two positioning plates 2061 that is close to each other. A mounting plate 207 is fixedly installed on one side of the two movable rods 206. A fixing rod 208 is symmetrically slidingly connected inside the mounting plate 207. One end of the fixing rod 208 is fixedly connected to the U-shaped frame 201. A telescopic spring 209 is sleeved on the outside of the two fixing rods 208 at one end of the mounting plate 207. The two ends of the telescopic spring 209 are fixedly connected to the fixing rod 208 and the mounting plate 207, respectively. A steel wire rope 210 is fixedly installed on the side of the mounting plate 207 near the U-shaped frame 201, and the end of the steel wire rope 210 away from the mounting plate 207 is fixedly connected to the connecting frame 205. Support blocks 211 are symmetrically installed on the side of the U-shaped frame 201 located on the fixed rod 208. At the same time, a guide wheel 212 is rotatably connected between the two support blocks 211, and the guide wheel 212 is rotatably connected to the steel wire rope 210. L-shaped brackets 227 are fixedly installed on the opposite sides of the positioning plate 2061, and top rods 228 are fixedly installed on the adjacent sides of the two L-shaped brackets 227, and ball bearings 229 are hinged to the adjacent ends of the two top rods 228. A geared motor 107 is fixedly installed at the top center of the workbench 1, and the output end of the geared motor 107 passes through the workbench 1 and is fixedly installed on a rotating plate 108. Three sliding grooves 109 are equidistantly opened on the top of the rotating plate 108. Meanwhile, a column block 110 is fixedly installed at the bottom of each of the three movable seats 105, and the column block 110 is slidably connected to the sliding groove 109.

[0028] Example 1: As Figures 1-4 and Figures 7-9As shown, when riveting and positioning the oven tube, the oven tube is spirally coiled. The coiled oven tube is supported and fixed by the fixing component 3. Then, when riveting the oven tube, the oven tube is placed inside the tube clamp 1011. The tube clamp 1011 can position the oven tube. Then, the reduction motor 107 can be started to drive the rotating plate 108 to rotate. After the rotating plate 108 rotates, the connection between the column block 110 and the sliding groove 109 can drive the three movable seats 105 to move away simultaneously. Then, the support column 106 can drive the U-shaped frame 201 to move. After the U-shaped frame 201 moves, the arc plate 203 abuts against the two coiled oven tubes. Then the U-shaped frame 201 continues to move, so that the U-shaped frame 201 can slide on the movable rod 202. During the movement of the U-shaped frame 201, the mounting plate 207 can be pulled forward by the steel wire rope 210. The movement of the mounting plate 207 causes it to slide on the fixing rod 208 and stretch the telescopic spring 209, thereby bringing the two positioning plates 2061 closer together to abut against the oven tube. This allows for further positioning of the oven tube. As the two positioning plates 2061 approach each other, the ball bearings 229 on the L-shaped bracket 227 abut against the slope of the tube clamp 1011. This movement of the positioning plates 2061 applies pressure to both ends of the tube clamp 1011, causing it to deform along the central fold. After deformation, the tube clamp 1011 can be riveted and positioned to secure the coiled oven tube. This allows for adaptive riveting of the oven tube according to its diameter and facilitates the fixing of tube clamps 1011 of different sizes, avoiding the need to replace riveting structures of different sizes and improving the overall usability.

[0029] Inside the U-shaped frame 201, a sliding rod 214 is slidably connected between two movable rods 202. One end of the sliding rod 214 is fixedly installed with an insert block 213. Inside the U-shaped frame 201, a guide rod 215 is slidably connected to one side of the sliding rod 214. One end of the guide rod 215 is fixedly connected to the insert block 213. A movable plate 216 is fixedly installed at the end of the sliding rod 214 and the guide rod 215 away from the insert block 213. A support spring 217 is sleeved on the outer side of the sliding rod 214. Both ends of the support spring 217 are fixedly connected to the movable plate 216 and the U-shaped frame 201, respectively. Support plates 218 are symmetrically installed on both sides of the U-shaped frame 201 and the movable plate 216. Columns 219 are symmetrically slidably connected inside the two support plates 218, and connecting plates 222 are slidably connected to one side of the two columns 219. Mounting brackets 220 are fixedly installed at one end of the two columns 219, and rubber wheels 221 are rotatably connected inside the mounting brackets 220. Return springs 223 are sleeved on the outside of the two columns 219 on one side of the connecting plate 222, and the two ends of the return springs 223 are fixedly connected to the connecting plate 222 and the column 219, respectively. Connecting rods 224 are symmetrically hinged to the side of the movable plate 216 away from the U-shaped frame 201, and the ends of the two connecting rods 224 away from the movable plate 216 are hinged to the two connecting plates 222, respectively. Both ends of the rubber wheel 221 pass through the mounting bracket 220 via a pivot and are fixedly mounted with ratchet 226. The mounting bracket 220 is located on one side of each of the two ratchet 226 and is hinged with ratchet 225. The ratchet 225 engages with the ratchet 226, and a torsion spring is provided at the connection between the ratchet 225 and the mounting bracket 220.

[0030] Example 2: Figures 2-3 and Figures 5-6As shown, during the riveting of the oven tubes, the movement of the U-shaped frame 201 first causes the insert 213 to abut against the two oven tubes. As the U-shaped frame 201 moves, the inclined sides of the insert 213 support the middle of the two oven tubes. After the insert 213 abuts, the U-shaped frame 201 continues to move, causing it to slide on the sliding rod 214. As the U-shaped frame 201 continues to move, it can drive the column rod 219 to move via the support plate 218. During the movement of the column rod 219, the connecting rod 224 rotates, thereby... The mounting bracket 220 is moved closer to the movable rod 202, causing the rubber wheel 221 to abut against the movable rod 202. Then, the U-shaped bracket 201 continues to move, and the connecting rod 224 continues to rotate, causing the connecting plate 222 to slide on the column rod 219 and stretch the return spring 223. Furthermore, when the movable rod 202 moves subsequently, it causes the abutting rubber wheel 221 to rotate counterclockwise. The ratchet 226 can engage the ratchet 225. After riveting is completed, the U-shaped bracket 201 is reset. When the U-shaped bracket 201 resets, due to… The insert 213 will not immediately disengage from the oven tube, and the connecting rod 224 will not rotate. If the movable rod 202 resets, it will drive the ratchet 226 to rotate clockwise. At this time, the ratchet 225 can prevent the rubber wheel 221 from rotating. The rubber wheel 221 is in close contact with the movable rod 202 to position the movable rod 202, thus preventing the positioning plate 2061 from resetting. When the U-shaped frame 201 resets and moves, the rubber pad on the positioning plate 2061 abuts against the oven tube. The resetting of the U-shaped frame 201 can adjust the riveted oven tube. By applying tension, it can be observed whether there is any separation or deformation between the oven tube and the tube clamp 1011. As the U-shaped frame 201 moves further during reset, the insert block 213 separates from the oven tube. Then, under the support spring 217, the rubber wheel 221 resets and no longer positions the movable rod 202. The positioning plate 2061 can be reset, so that the riveting strength of the oven tube can be tested after riveting. If there is any looseness in the oven tube riveting, it can be detected in time, thus improving the processing quality of the oven tube.

[0031] Fixed component 3 is installed on one side of the output end of electric push rod 102; The fixing component 3 includes a movable frame 301 fixedly installed at the movable end of the electric push rod 102, and a pipe clamp 1011 is located inside the movable frame 301. Two sets of fixing blocks 302 are symmetrically installed on both sides of the pipe clamp 1011 inside the movable frame 301. Positioning rods 303 are slidably connected inside each of the two fixing blocks 302 on each side. A clamping plate 304 is fixedly installed at one end of each of the two positioning rods 303. A tension spring 305 is sleeved on the outside of each of the two positioning rods 303 on one side of the fixing block 302. The two ends of the tension spring 305 are fixedly connected to the fixing block 302 and the positioning rod 303 respectively. The tension spring 305 is in a stretched state. Fixing plates 306 are fixedly installed inside the two clamping plates 304 that are far apart. Conical blocks 307 are fixedly installed on the side of the two fixing plates 306 that are close together. The two conical blocks 307 are located inside the fold of the pipe clamp 1011.

[0032] Example 3: Figure 1 and Figure 8 As shown, when fixing the pipe clamp 1011, the two clamping plates 304 are moved away from each other, causing the positioning rod 303 to slide on the fixing block 302 and the tension spring 305 to deform. Then, the pipe clamp 1011 is placed inside the movable frame 301 and the clamping plates 304 are released. Under the action of the tension spring 305, the two clamping plates 304 move closer together to clamp and fix the pipe clamp 1011. At the same time, the tension spring 305 is in a stretched state, and the cone block 307 is located in the middle fold of the pipe clamp 1011. During the riveting process, the fold in the middle of the pipe clamp 1011 deforms and closes continuously. During the closing process, the fold of the pipe clamp 1011 can be pushed by the oblique side of the cone block 307 to move, and then the clamping plate 304 is driven away from the pipe clamp 1011 through the fixing plate 306. After the pipe clamp 1011 is riveted and deformed, the fold closes, and the clamping plate 304 is removed from the pipe clamp 1011. Subsequently, the movable frame 301 can be directly removed without disassembling the pipe clamp 1011, which improves the convenience of operation.

[0033] Working principle: When using this oven tube riveting processing equipment, firstly, according to... Figures 1-9As shown, when riveting and positioning the oven tubes, the oven tubes are spirally coiled. The coiled oven tubes are supported and fixed by the fixing component 3. Then, when riveting the oven tubes, the oven tubes are placed inside the tube clamp 1011. The tube clamp 1011 can position the oven tubes. Then, the reduction motor 107 can be started to drive the rotating plate 108 to rotate. After the rotating plate 108 rotates, the connection between the column block 110 and the sliding groove 109 can drive the three movable seats 105 to move away simultaneously. Then, the support column 106 can drive the U-shaped frame 201 to move. After the U-shaped frame 201 moves, the arc plate 203 abuts against the two coiled oven tubes. Then the U-shaped frame 201 continues to move, so that the U-shaped frame 201 can... The movable rod 202 slides, and the U-shaped frame 201 moves by pulling the mounting plate 207 through the steel wire rope 210. This causes the mounting plate 207 to slide on the fixed rod 208 and stretch the telescopic spring 209, thereby bringing the two positioning plates 2061 closer together and abutting against the oven tube. This allows for further positioning of the oven tube. At the same time, the ball bearings 229 on the L-shaped frame 227 abut against the slope of the tube clamp 1011. As the positioning plates 2061 move, pressure is applied to both ends of the tube clamp 1011, causing the tube clamp 1011 to deform along the middle fold. After the tube clamp 1011 deforms, it can be riveted and positioned to hold the coiled oven tube in place. When riveting the oven tubes, the movement of the U-shaped frame 201 first causes the insert block 213 to abut against the two oven tubes. As the U-shaped frame 201 moves, the two inclined sides of the insert block 213 support the middle of the two oven tubes. After the insert block 213 abuts, the U-shaped frame 201 continues to move, causing it to slide on the sliding rod 214. As the U-shaped frame 201 continues to move, it can drive the column rod 219 to move via the support plate 218. During the movement of the column rod 219, the connecting rod 224 rotates, thereby causing the mounting bracket 220 to move closer to the movable rod 202, so that the rubber wheel 221 abuts against the movable rod 202. Afterward, the U-shaped frame 201 continues to move, and the connecting rod 224 continues to rotate. This allows the connecting plate 222 to slide on the column rod 219 and stretch the return spring 223. When the subsequent movable rod 202 moves, it drives the abutting rubber wheel 221 to rotate counterclockwise. The ratchet 226 can engage the ratchet 225. After riveting, the U-shaped frame 201 is reset. When the U-shaped frame 201 resets, since the insert block 213 will not immediately leave the oven tube, the connecting rod 224 will not rotate. If the movable rod 202 resets, it will drive the ratchet 226 to rotate clockwise. At this time, the ratchet 225 prevents the rubber wheel 221 from rotating. The rubber wheel 221 and the movable rod 202 are tightly pressed together to position the movable rod 202, thus preventing the positioning plate 2061 from resetting. When the U-shaped frame 201 resets and moves, the rubber pad on the positioning plate 2061 abuts against the oven tube. The reset of the U-shaped frame 201 applies tension to the riveted oven tube, allowing observation of whether the oven tube and the tube clamp 1011 have detached and deformed. As the reset distance of the U-shaped frame 201 increases, the insert block 213 detaches from the oven tube, causing the rubber wheel 221 to reset under the support spring 217, thus no longer positioning the movable rod 202. The positioning plate 2061 can then reset. When fixing the tube clamp 1011, the two clamping plates 304 are moved away from each other, causing the positioning rod 303 to slide on the fixing block 302 and deforming the tension spring 305. Then, the tube clamp is... 1011 is placed inside the movable frame 301 and the clamping plate 304 is released. Under the action of the tension spring 305, the two clamping plates 304 approach each other to clamp and fix the pipe clamp 1011. At the same time, the tension spring 305 is in the tension state. The cone block 307 is located in the middle fold of the pipe clamp 1011. During the riveting process, the middle fold of the pipe clamp 1011 deforms and closes continuously. During the closing process, the fold of the pipe clamp 1011 can be pushed by the oblique side of the cone block 307 to move, and then the clamping plate 304 is driven away from the pipe clamp 1011 through the fixing plate 306. After the pipe clamp 1011 is riveted and deformed, the fold closes, and the clamping plate 304 leaves the pipe clamp 1011. It can then be directly removed from the movable frame 301.
