Description

Technical Field

[0001] The present invention relates to the technical field of brazing furnaces, and particularly to an ultra-long production equipment and process for the running belt of a brazing furnace. Background Art

[0002] At present, high-temperature brazing of large-area and heavy workpiece complex structural parts mainly uses vacuum brazing, but vacuum brazing has high costs and low efficiency; for a continuous atmosphere-protected mesh belt brazing furnace, a mesh belt needs to continuously run on a muffle tank. Since both the muffle tank and the mesh belt are made of 310S stainless steel, their load-bearing capacity at high temperatures is very poor, and it can only meet the batch brazing of small workpieces and is not suitable for brazing large-area heavy workpieces; moreover, for this continuous atmosphere-protected mesh belt brazing furnace suitable for small workpieces, the muffle tank and the stainless steel mesh belt need to be replaced once a year, and the cost of each replacement is more than 100,000 yuan, resulting in high maintenance costs.

[0003] The patent document with the patent number CN2016205140099 discloses a brazing furnace mesh belt, including a mesh belt. The mesh belt includes a number of latitudinal stringers and spiral mesh bars. Adjacent mesh bars respectively extend spirally in counterclockwise and clockwise directions, and the wave valleys on the mesh bars extending spirally in the counterclockwise direction and the wave peaks on the mesh bars extending spirally in the clockwise direction are alternately distributed on the stringers and are connected in series by the stringers; thus, the positions of each spiral bar are correctly positioned, so as to minimize the deformation and extension of the mesh belt.

[0004] However, in the actual use process, the inventor found that when the running belt of the brazing furnace in the above scheme is produced by traditional equipment, during the use process, sliding friction occurs between the mesh bars and the stringers, resulting in relatively serious wear, a short service life of the running belt, and high maintenance costs. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art. By providing an ultra-long production equipment for the running belt of a brazing furnace, it is possible to embed ball bearings at the inner bending points of the wavy stringers, so that the contact between the spiral mesh bars and the wavy stringers is changed from sliding friction to rolling friction, reducing the frictional force, increasing the service life of the running belt, saving the driving energy consumption of the running belt, and thus solving the technical problems of relatively serious wear, short service life, and high maintenance costs of the running belt of the brazing furnace produced by traditional equipment.

[0021] Preferably, a production process of a production device for an ultra-long brazing furnace running belt includes the following steps:

[0022] Step 1, the material-laying process: The spiral wire strips are laid flat and arranged crosswise on the carrier belt. The cross-gap between two adjacent spiral wire strips facilitates the penetration of the wavy string. The positioning component limits the spiral wire strips on the carrier belt, and the carrier belt intermittently conveys the spiral wire strips forward.

[0023] Step 2, the string-forming process: During the process of the string penetrating into the gap between two adjacent crossed spiral wire strips, the bending component processes the string into a wavy shape. The grooving component opens a groove at the inner bending part of the wavy string. The bead-inserting component first cleans the waste chips in the groove of the wavy string, and then sends the ball into the groove of the wavy string. The bead-sealing component bonds the iron ring at the opening of the groove of the wavy string to prevent the ball from detaching from the groove of the wavy string.

[0024] Step 3, the assembling process: After the wavy string completely penetrates into the gap between two adjacent spiral wire strips, the rubber roller mechanism drives the front spiral wire strip to move forward a specified distance together with the wavy string, so that the bending parts of two adjacent spiral wire strips are simultaneously in close contact with the balls at the bending parts of the wavy string, thereby positioning the distance between two adjacent wavy strings of the running belt and facilitating the installation of the chain.

[0025] Step 4, the edge-sealing process: After the distance between two wavy strings is positioned, the edge-sealing mechanism respectively installs the chain plates on the ends of two adjacent wavy strings from both sides to form a chain in sequence, and sinter the ends of the wavy strings to prevent the chain plates from detaching from the ends of the wavy strings, and produce an ultra-long brazing furnace running belt in sequence.

[0026] The beneficial effects of the present invention:

[0027] (1) In the present invention, through the cooperation of the forming mechanism and the assembling mechanism, on the one hand, it is possible to embed the balls at the inner bending positions of the wavy strips, so that the sliding friction between the assembled spiral strips and the wavy strips is improved to rolling friction, greatly reducing the wear caused by friction between the spiral strips and the wavy strips, increasing the service life of the running belt, reducing the maintenance cost of the brazing furnace. At the same time, the reduction of the friction force between the spiral strips and the wavy strips can also save the driving force for the operation of the running belt and reduce energy consumption. On the other hand, it can automatically and continuously assemble and produce the running belt, and the positioning and arrangement of the spiral strips are relatively neat, facilitating the penetration of the wavy strips into the gaps between adjacent two spiral strips, with precise and stable assembly.

[0028] (2) In the present invention, through the cooperation of the pushing component and the bending component, on the one hand, it can automatically process the straight strips into a wavy shape and horizontally push the wavy strips into the gaps between adjacent two spiral strips, facilitating the spiral strips to be wound around the inner bending positions of the wavy strips, with accurate positioning and reducing the deformation and extension of the spiral strips. On the other hand, during the process of bending the straight strips, it can open grooves at the inner bending positions of the wavy strips, facilitating the installation of balls at the inner bending positions of the wavy strips, with good structural linkage and high automation.

[0029] (3) In the present invention, through the cooperation of the bead-inserting component and the bead-sealing component, on the one hand, it can first clean the waste chips at the inner bending positions of the strips, facilitating the installation of the balls in the grooves at the inner bending positions of the strips, ensuring the smooth rolling of the balls in the grooves and increasing the firmness of the iron rings bonded to the inner bending positions of the strips. On the other hand, it can seal the balls in the grooves at the inner bending positions of the strips, preventing the balls from detaching from the grooves at the inner bending positions of the strips and ensuring the stability of the balls during operation.

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0054] Embodiment 1

[0055] As Figure 1-21 shown, a production device for an ultra-long brazing furnace running belt includes a transportation mechanism 2 arranged on a frame 1, a forming mechanism 3 arranged on the frame 1, an assembly mechanism 4 arranged on the frame 1, and an edge-sealing mechanism 5 arranged on the frame 1;

[0056] The forming mechanism 3 includes a pusher component 31 arranged on the frame 1, a bending component 32 arranged on the pusher component 31 and used for processing a string into a wavy shape, a drilling component 33 arranged on the bending component 32 and used for grooving at the inner bending part of the string, a bead-inserting component 34 arranged on the pusher component 31 and used for inserting beads into the grooves of the wavy string, and a bead-sealing component 35 arranged on the pusher component 31 and used for sealing the beads in the grooves of the string;

[0057] The transportation mechanism 2 intermittently conveys the flat and cross-arranged spiral wire meshes 6 forward. The pusher component 31 sequentially pushes single straight strings onto the spiral wire meshes 6 on the transportation mechanism 2. During the process of the string passing through the gap between two adjacent crossed spiral wire meshes 6, the bending component 32 processes the string into a wavy shape. The drilling component 33 grooves at the inner bending part of the wavy string 7. The bead-inserting component 34 inserts beads 8 into the grooves of the wavy string 7. The bead-sealing component 35 bonds an iron ring at the opening of the groove of the wavy string 7 to prevent the beads from detaching from the groove of the wavy string. After the wavy string passes through the gap between two adjacent spiral wire meshes, the assembly mechanism 4 drives the front spiral wire mesh to move forward a specified distance together with the wavy string, so that the bending parts of two adjacent spiral wire meshes 6 are simultaneously in close contact with the beads 8 at the bending parts of the wavy string 7, thereby positioning the distance between two wavy strings on the running belt. The edge-sealing mechanism 5 respectively installs chain plates 9 on the ends of two adjacent wavy strings from both sides to form a chain in sequence, thereby successively producing an ultra-long brazing furnace running belt;

[0058] There is rolling friction between the spiral wire mesh and the wavy string of the running belt, reducing the wear rate.

[0059] It should be noted that the spiral wire mesh 6 is a pre-processed finished product and can be directly used in this embodiment.

[0060] In this embodiment, by cooperating with the setting of the forming mechanism 3 and the assembling mechanism 4, on the one hand, the ball bearings can be embedded in the inner bend of the wavy string 7, so that the contact sliding friction between the assembled spiral mesh strips and the wavy string strips is improved to rolling friction, which greatly reduces the wear caused by friction between the spiral mesh strips and the wavy string strips, improves the service life of the running belt, and reduces the maintenance cost of the brazing furnace. At the same time, the friction between the spiral mesh strips and the wavy string strips is reduced, which can also save the driving force of the running belt and reduce energy consumption; on the other hand, the running belt can be automatically and continuously assembled and produced, and the positioning and arrangement of the spiral mesh strips are relatively neat, which facilitates the wavy string strips to penetrate into the gap between two adjacent spiral mesh strips, and the assembly is precise and stable.

[0061] In detail, first, the spiral mesh strips 6 are laid flat and cross-arranged on the carrier belt 212, and the cross gap between two adjacent spiral mesh strips facilitates the insertion of the wavy string strips 7. The positioning component 22 limits the spiral mesh strips on the carrier belt 212, and the carrier belt 212 carries the spiral mesh strips and transports them forward intermittently; then, in the process of the string strips inserting into the gap between two adjacent crossed spiral mesh strips, the bending component 32 processes the string strips into a wavy shape, the drilling groove component 33 grooves the inner bend of the wavy string strips, the bead embedding component 34 first cleans the waste chips in the groove of the wavy string strips, and then sends the balls 8 into the groove of the wavy string strips, and the bead sealing component 35 bonds the iron ring to the opening of the groove of the wavy string strips to prevent the balls from falling off the wavy The groove of the wavy string; then, after the wavy string is completely inserted into the gap between two adjacent spiral mesh strips, the rubber roller 42 drives a spiral mesh strip in front to move forward a specified distance with the wavy string, so that the bending parts of the two adjacent spiral mesh strips are in close contact with the balls at the bending parts of the wavy string strips at the same time, thereby positioning the spacing between the two adjacent wavy strings of the running belt, which is convenient for installing the chain; then, after the spacing between the two wavy strings is positioned, the edge sealing mechanism 5 installs the chain plates 9 on the ends of the two adjacent wavy strings from both sides to form a chain in sequence, and sinters the ends of the wavy strings to prevent the chain plates from detaching from the ends of the wavy strings, thereby producing ultra-long brazing furnace running belts in sequence.

[0062] Preferably, the spiral mesh strip 6 can also be formed by spirally forming a flat wire.

[0063] Further, if Figure 4-9 As shown, the transport mechanism 2 includes a carrying assembly 21 disposed on the frame 1 and a positioning assembly 22 disposed on the carrying assembly 21;

[0064] The carrying assembly 21 includes two sets of driving rollers 211 arranged on the frame 1, a carrying belt 212 arranged between the two driving rollers 211, and a first stepping motor 213 arranged on the frame 1;

[0065] The positioning component 22 includes a number of lifting rods 221 arranged in rows along the driving direction of the conveyor belt 212, penetrating through the conveyor belt 212 and used to limit the position of the spiral wire strip 6, a connecting plate 222 arranged between the lower ends of the single row of lifting rods 221, a first elastic member 223 arranged between the connecting plate 222 and the bottom of the conveyor belt 212, extension rods 224 arranged at both ends of the connecting plate 222, two groups of limiting tracks 225 symmetrically arranged on the frame 1 and used to drive the extension rods 224 to drive the lifting rods 221 to descend, and a number of leveling rollers 226 arranged on the frame 1 and used to flatten the spiral wire strip on the conveyor belt 212.

[0066] It should be noted that a strip-shaped groove for avoiding the connecting plate 222 of the positioning component 22 is longitudinally formed on the circumferential side of the driving roller 211 to ensure that the driving roller 211 can stably drive the conveyor belt 212;

[0067] In this embodiment, through the arranged transportation mechanism 2, on the one hand, it can neatly arrange and position the spiral wire strip 6, facilitating the wave-shaped strip to penetrate into the gap between two adjacent spiral wire strips. On the other hand, it can intermittently drive the spiral wire strip 6 to move forward to ensure that a complete running belt can be continuously and automatically assembled.

[0068] Specifically, first, the spiral wire strip 6 is manually or mechanically placed on the conveyor belt 212 in sequence, so that the spiral wire strips 6 are laid flat and cross-arranged in sequence, and the position of each spiral wire strip 6 is limited by the lifting rod 221. During the process that the conveyor belt 212 drives the spiral wire strip 6 to move forward intermittently, the leveling roller 226 flattens the spiral wire strip 6. When the gap between two adjacent spiral wire strips 6 advances to the position of the forming channel 316, the conveyor belt 212 stops running. After the wave-shaped strip is completely penetrated into the gap between the two spiral wire strips 6 by the pushing component 31, the conveyor belt 212 continues to drive the spiral wire strip 6 to move forward. When the extension rod 224 passes through the position of the limiting track 225, the limiting track 225 drives the extension rod 224 to drive the connecting plate 222 and the lifting rod 221 to descend, so that the lifting rod 221 disengages from the spiral wire strip 6, facilitating the horizontal movement of the spiral wire strip 6 in front and facilitating the work of the assembling mechanism 4.

[0069] Furthermore, as Figure 4-15As shown in the figure, the pushing component 31 includes a cross plate 311 arranged on the frame 1, a first material cylinder 312 arranged on the cross plate 311 and internally filled with a straight strip, a material receiving strip seat 313 arranged on one side surface of the cross plate 311 and located directly below the first material cylinder 312, a first hydraulic component 314 arranged on the outer wall of the first material cylinder 312 through a bracket, a pushing strip 315 arranged on the output shaft of the first hydraulic component 314, a forming channel 316 arranged on the other side surface of the cross plate 311 for forming a wavy strip, and a circular channel 317 arranged on the side surface of the cross plate 311 for connecting the forming channel 316 and the material receiving strip seat 313;

[0070] The bending component 32 includes a frame 321 arranged at the bottom of the forming channel 316, a bidirectional threaded rod 322 horizontally rotatably arranged on the frame 321, two groups of symmetrically arranged moving blocks 323 threadedly arranged on the bidirectional threaded rod 322, side plates 324 arranged on the moving blocks 323, a U-shaped bending frame 325 penetratingly arranged on the side plates 324, a second elastic member 326 arranged between the end of the U-shaped bending frame 325 and the side plates 324, two groups of bending openings 327 respectively arranged on both side surfaces of the forming channel 316 and adapted to the U-shaped bending frame 325, and a second stepping motor 328 arranged on the frame 321 for driving the bidirectional threaded rod 322;

[0071] The drilling groove component 33 includes a drill rod 331 rotatably arranged on the side plate 324, an avoidance hole 332 arranged on the U-shaped bending frame 325 for the drill rod 331 to pass through, and a third stepping motor 333 arranged on the side plate 324 for driving the drill rod 331.

[0072] It is worth mentioning that the elastic force of the second elastic member 326 is greater than the bending force of the straight strip, ensuring that the U-shaped bending frame 325 can bend the straight strip. After the straight strip is bent, the second elastic member 326 is stretched and deformed, and then the drilling groove component 33 works;

[0073] In this embodiment, through the cooperation of the pushing component 31 and the bending component 32, on the one hand, it can automatically process the straight strip into a wavy shape and horizontally push the wavy strip into the gap between two adjacent spiral wire strips, which is convenient for the spiral wire strip to be wound around the inner bending part of the wavy strip, with accurate positioning and reduced deformation and extension of the spiral wire strip; on the other hand, it can open a groove at the inner bending part of the wavy strip during the process of bending the straight strip, which is convenient for installing balls at the inner bending part of the wavy strip, with good structural linkage and high automation.

[0074] Specifically, when the gap between two adjacent spiral wire rods 6 advances to the position at the end of the forming channel 316, the carrier belt 212 stops operating. The first cartridge 312 drops a straight strip onto the receiving strip seat 313. The first hydraulic component 314 drives the pushing strip 315 to push the straight strip on the receiving strip seat 313 into the circular channel 317 of the cross plate 311. The straight strip enters the forming channel 316 from the circular channel 317. The pushing strip 315 pushes the straight strip to intermittently advance a specified distance. The second stepping motor 328 drives two moving blocks 323 to move towards the forming channel 316 through the bidirectional threaded rod 322, so that two U-shaped bending frames 325 respectively pass through the bending openings 327 and enter the interior of the forming channel 316. The U-shaped bending frames 325 bend the straight strip, and press the bent part of the strip against the inner side wall of the forming channel 316. Then, the bidirectional threaded rod 322 continues to drive the moving blocks 323 and the side plates 324 to move towards the forming channel 316, so that the side plates 324 and the U-shaped bending frames 325 move relatively, stretching the second elastic member 326 to deform, so that the end of the drill rod 331 passes through the avoidance hole 332 of the U-shaped bending frame 325 and abuts against the inner bent part of the strip. The third stepping motor 333 drives the drill rod 331 to groove the inner bent part of the strip. Finally, the second stepping motor 328 drives the U-shaped bending frame 325 and the drill rod 331 to move away from the forming channel 316 for resetting, waiting for the next use.

[0075] Further, as Figure 10-18 shown, the bead-inserting assembly 34 includes two groups of synchronizing rods 341 respectively arranged on the moving blocks 323, two groups of air bags 342 arranged on the side of the frame through ear plates, jet nozzles arranged on the air bags 342, pressing plates 343 arranged on the synchronizing rods 341 through L-shaped support rods, two groups of dust removal ports 344 respectively opened on both side surfaces of the forming channel 316, two groups of second cartridges 345 arranged on the side of the forming channel through ear plates and filled with balls inside, a feeding channel 346 arranged at the lower port of the second cartridge 345, mounting blocks 347 arranged on the synchronizing rods 341 and slidably matched with the frame 321, vacuum suction pipes 348 arranged on the mounting blocks 347, vacuum generators arranged on the mounting blocks 347, and two groups of bead-inserting ports 349 respectively opened on both side surfaces of the forming channel 316. The vacuum suction pipe 348 can suck the balls in the feeding channel 346 and send the balls from the bead-inserting port 349 into the groove at the inner bent part of the strip;

[0076] The bead sealing assembly 35 includes two groups of third barrels 351 with iron rings installed on the side of the forming channel through ear plates, a pushing channel 352 arranged at the lower end of the third barrel 351, a glue coating roller 353 embedded and rotatably arranged on the side wall of the third barrel 351, a glue filling barrel 354 arranged on the outer wall of the third barrel 351, a synchronization block 355 arranged on the synchronization rod 341 and slidingly matched with the frame 321, a push rod 356 arranged on the synchronization block 355 and adapted to the pushing channel 352, an electromagnet block 357 arranged at the end of the push rod 356, and two groups of bead sealing openings 358 respectively opened on both sides of the forming channel 316. The electromagnet block 357 is magnetic when energized and can absorb the iron ring in the pushing channel 352 and send the iron ring from the bead sealing opening 358 to the groove opening at the inner bending of the string. The electromagnet block 357 loses its magnetism after power is turned off, and the push rod 356 resets the electromagnet block 357 with it.

[0077] It is worth mentioning that the side of the iron ring can fit tightly with the inner bend of the string, ensuring that the iron ring can be bonded to the inner bend of the string;

[0078] It should be noted that the iron ring is installed upright in the third barrel 351, and the glue on the glue roller 353 is an inorganic high temperature resistant glue to ensure the stability of the iron ring bonding;

[0079] In this embodiment, by cooperating with the bead embedding assembly 34 and the bead sealing assembly 35, on the one hand, the waste chips at the inner bend of the string strip can be cleaned first, so that the ball can be installed in the groove at the inner bend of the string strip conveniently, thereby ensuring the smoothness of the rolling of the ball in the groove and improving the firmness of the iron ring bonded to the inner bend of the string strip; on the other hand, the ball can be sealed in the groove at the inner bend of the string strip to prevent the ball from escaping from the groove at the inner bend of the string strip, thereby ensuring the stability of the ball operation.

[0080] Specifically, after the bending component 32 and the grooving component 33 complete their work, the first hydraulic component 314 drives the push bar 315 to continue pushing the linear string forward by a specified distance. When the bending component 32 works again, the bidirectional threaded rod 322 drives the moving block 323 to move towards the forming channel 316. The moving block 323 drives the pressing disc 343, the mounting block 347, and the synchronous block 355 to also move towards the forming channel 316 through the synchronous rod 341, causing the pressing disc 343 to squeeze the airbag 342. The jet nozzle blows air through the dust removal port 344 to clean the waste chips at the bent part inside the string. At the same time, the mounting block 347 drives the vacuum suction pipe 348 to push the balls in the feeding channel 346 from the bead embedding port 349 into the groove at the bent part inside the string. At the same time, the iron rings in the third cartridge 351 are smeared with glue by the glue applicator roller 353 and then fall into the feeding channel 352. The synchronous block 355 drives the push rod 356 and the electromagnet block 357 to send the iron rings in the feeding channel 352 from the bead sealing port 358 to the opening of the groove at the bent part inside the string, so that the iron rings are bonded to the opening of the groove at the bent part inside the string, thus sealing the balls in the groove at the bent part inside the string. Finally, the bidirectional threaded rod 322 drives the bead sealing component 35 and the bead embedding component to reset for the next use.

[0081] Furthermore, as Figure 4 and Figure 19-20 shown, the assembling mechanism 4 includes a rubber roller 42 rotatably arranged on the frame 1 through two sets of vertical plates 41 and a fourth stepping motor arranged on one of the vertical plates 41 and used to drive the rubber roller 42.

[0082] It is worth mentioning that, as Figure 20 shown, the wavy string 7 penetrates into the gap between two adjacent spiral-shaped mesh strips 6. During the process of the rubber roller 42 driving the previous spiral-shaped mesh strip 6 to slide forward, the previous spiral-shaped mesh strip 6 forces the spiral-shaped mesh strip 6 before it to slide forward.

[0083] In this embodiment, by setting the assembling mechanism 4, the gap between two adjacent spiral-shaped mesh strips 6 can be reduced, so that two adjacent spiral-shaped mesh strips 6 are coiled at the bent part of the wavy string 7. The bent parts of the two spiral-shaped mesh strips 6 are in close contact with the balls 8 at the bent part of the wavy string 7 at the same time, thereby positioning the distance between two wavy strings on the running belt.

[0084] Specifically, after the wavy string bar 7 is completely inserted into the gap between two adjacent spiral wire bars 6, the carrier belt 212 carries the spiral wire bars 6 and the wavy string bar 7 forward by a specified distance, so that the positioning assembly 22 loses the limit on the previous spiral wire bar 6. After the previous spiral wire bar 6 moves to the position below the rubber roller 42, the carrier belt 212 stops operating. The fourth stepping motor drives the rubber roller 42 to rotate, and the rubber roller 42 drives the previous spiral wire bar 6 to slide forward and drives the wavy string bar 7 to slide forward by a certain distance, thereby reducing the gap between two adjacent spiral wire bars 6, so that the two adjacent spiral wire bars 6 are coiled around the bent portion of the wavy string bar 7. The bent portions of the two spiral wire bars 6 are in close contact with the balls 8 at the bent portion of the wavy string bar 7 at the same time, thereby positioning the position of the wavy string bar and making the wavy string bar located at the position of the edge sealing mechanism 5.

[0085] Further, as Figure 4 and Figure 19-21 shown, the edge sealing mechanism 5 includes two sets of slideways 51 symmetrically arranged on the frame 1 and used for limiting the chain plates 9, a transfer channel 52 communicated with the side of the slideway 51, a fourth cartridge 53 arranged on the transfer channel 52 and containing chain plates inside, a second hydraulic member 54 arranged at the end of the transfer channel 52, an L-shaped push plate 55 arranged at the output end of the second hydraulic member 54, a melting groove 56 opened on the L-shaped push plate 55 and used for sintering the end of the wavy string bar, and an electric heating plate arranged inside the melting groove 56.

[0086] It should be noted that the melting groove 56 can melt the end of the wavy string bar and make the end of the wavy string bar have knots to prevent the chain plate 9 from detaching from the end of the wavy string bar;

[0087] It is worth mentioning that there is only one melting groove 56 on the L-shaped push plate 55. After two chain plates 9 are both installed at one end of the wavy string bar, the melting groove 56 on the L-shaped push plate 55 sinter the end of the wavy string bar. When only one chain plate 9 is installed at the end of the wavy string bar, it is not sintered, and it is sintered after another chain plate 9 is installed;

[0088] In this embodiment, by setting the edge sealing mechanism 5, the distance between two adjacent wavy string bars can be limited, the flatness of the running belt can be ensured, and the chain plates 9 can be assembled into a chain to facilitate the operation of the running belt.

[0089] Specifically, after the assembling mechanism 4 drives the wavy string bar to the position of the edge sealing mechanism 5, the second hydraulic member 54 pushes the chain plate 9 in the transfer channel 52 into the slideway 51 through the L-shaped push plate 55, so that the chain plate 9 is installed between the end of the wavy string bar and the end of the previous wavy string bar. At the same time, the melting groove 56 on the L-shaped push plate 55 sinters the end of the previous wavy string bar.

[0090] Preferably, the chains on each side of the running belt can also be double-stranded to increase strength, that is, the edge-sealing mechanism 5 pushes two chain plates 9 each time and installs them at one end of two adjacent wavy strings.

[0091] Embodiment 2

[0092] As Figure 1-22 shown, a production process of a production equipment for an ultra-long brazing furnace running belt includes the following steps:

[0093] Step 1, feeding process: The spiral wire strips 6 are laid flat and arranged crosswise on the carrier belt 212. The cross gaps between two adjacent spiral wire strips facilitate the penetration of the wavy strings 7. The positioning assembly 22 limits the spiral wire strips on the carrier belt 212, and the carrier belt 212 intermittently conveys the spiral wire strips forward.

[0094] Step 2, string forming process: During the process of the string penetrating into the gaps between two adjacent crossed spiral wire strips, the bending assembly 32 processes the string into a wavy shape. The grooving assembly 33 opens grooves at the inner bending parts of the wavy string. The bead-inserting assembly 34 first cleans the waste chips in the grooves of the wavy string, and then sends the balls 8 into the grooves of the wavy string. The bead-sealing assembly 35 bonds the iron rings at the openings of the grooves of the wavy string to prevent the balls from detaching from the grooves of the wavy string.

[0095] Step 3, assembling process: After the wavy string completely penetrates into the gaps between two adjacent spiral wire strips, the rubber roller 42 drives a spiral wire strip in front to move forward a specified distance together with the wavy string, so that the bending parts of two adjacent spiral wire strips are simultaneously in close contact with the balls at the bending parts of the wavy string, thereby positioning the distance between two adjacent wavy strings of the running belt and facilitating the installation of the chain.

[0096] Step 4, edge-sealing process: After the distance between two wavy strings is positioned, the edge-sealing mechanism 5 installs the chain plates 9 on the ends of two adjacent wavy strings from both sides in sequence to form a chain, and sinters the ends of the wavy strings to prevent the chain plates from detaching from the ends of the wavy strings, thereby producing an ultra-long brazing furnace running belt in sequence.
