Description

Technical Field

[0001] This invention belongs to the field of mixed-wire welding machine technology, specifically a mixed-wire welding machine inlet clamping mechanism. Background Technology

[0002] In continuous production lines for metal strips, mixed-line welding machines are key equipment for achieving efficient butt welding of strips of different specifications and materials. The performance of its inlet clamping mechanism directly affects the welding quality and the stability of the production line. The core function of this mechanism is to precisely position and secure the strip head through symmetrically arranged clamping components during the strip threading and welding preparation stages, ensuring the alignment of the strips during butt welding and providing a reliable clamping foundation for subsequent welding processes.

[0003] During daily use, especially during the threading process, deviation of the strip direction can scratch the drive rod of the hydraulic cylinder. When the drive rod retracts into the hydraulic cylinder, it damages the shaft seal, causing oil leakage from the hydraulic cylinder and creating a safety hazard. Therefore, the cylinder rod and shaft seal need to be replaced once a quarter. The consumption of spare parts is large, resulting in equipment failure downtime and affecting the production line output.

[0004] It is necessary to prevent the strip steel from scratching the drive rod on the hydraulic cylinder, thereby preventing damage to the shaft seal when the drive rod retracts into the hydraulic cylinder. An extension rod is installed to prevent the strip steel from scratching the drive rod, thus avoiding damage to the drive rod. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides an inlet clamping mechanism for a mixed-wire welding machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an inlet clamping mechanism for a mixed-wire welding machine, comprising a hydraulic cylinder, a positioning sleeve installed at the bottom end of the hydraulic cylinder, a mounting base fixed at the bottom end of the positioning sleeve, an upper clamp fixed to the outside of the mounting base, a protective mechanism installed at the bottom end of the hydraulic cylinder, a base provided at the bottom end of the protective mechanism, a lower clamp fixed to the outside of the base, an oiling mechanism installed at the top end of the base, and a disassembly and assembly mechanism installed on the outside of the base; The protective mechanism includes a drive rod, an extension rod, and a thrust bearing. The drive rod is fixed to the extension end of the hydraulic cylinder. An extension rod is welded to the bottom end of the drive rod. A thrust bearing is fixed to the outside of the extension rod.

The support rod is fixed to the top of the base. An oil reservoir is sleeved on the outside of the support rod. An oil-impregnated felt is connected to the outside of the oil reservoir. A limit magnetic block is provided on the outside of the oil-impregnated felt.

[0007] Preferably, there are two sets of drive rods and extension rods, which are symmetrically distributed about the central axis of the base. The inner ring of the thrust bearing is fixed with an extension rod, and the outer ring of the thrust bearing is fixed with a protective disc. There are two sets of thrust bearings, which are symmetrically distributed about the central axis of the extension rods.

[0008] Preferably, a first return spring is fixed to the outside of the support rod, a recycling groove is provided at the top of the base, a conveying pump is fixed at the top of the base, a first conveying pipe is connected to the bottom of the conveying pump, and a second conveying pipe is connected to the top of the conveying pump.

[0009] Preferably, there are two sets of support rods, which are symmetrically distributed about the central axis of the base. The inner wall of the oil storage cylinder is attached to the outer wall of the support rod. The oil storage cylinder and the support rod are rotatably connected. The outer surface of the oil-impregnated felt is in contact with the protective disc.

[0010] Preferably, four sets of limiting magnetic blocks are provided, the limiting magnetic blocks are arranged in an array, the inner wall of the oil storage cylinder is made of iron material, and the limiting magnetic blocks and the inner wall of the oil storage cylinder are magnetically connected.

[0011] Preferably, the bottom end of the first reset spring is fixed with an oil storage cylinder, the first reset spring is used to squeeze the first reset spring and keep it in a rotating tendency, the bottom end of the recycling tank is provided with an inclined surface, and the output end of the first conveying pipe is connected to the oil storage cylinder.

[0012] Preferably, the disassembly and assembly mechanism includes a protective cover, a guide groove, and a limiting hole. The protective cover is movably connected to the outside of the base. One end of the protective cover has a guide groove, and the outside of the protective cover has a limiting hole. A limiting rod is movably connected inside the base. One end of the limiting rod is fixed with a trigger head, and a second return spring is installed on the outside of the limiting rod. The protective cover is precisely aligned with the base through the guide groove to avoid positional deviation during installation. The limiting rod automatically engages with the limiting hole under the action of the second return spring, and fixation can be completed without additional tools.

[0013] Preferably, the protective cover is provided in two sets, the protective cover is symmetrically distributed about the central axis of the base, the outer wall of the protective cover is attached to the inner wall of the base, the protective cover and the base are slidably connected, and the guide groove is an inclined surface.

[0014] Preferably, two sets of limiting holes are provided, and the limiting holes are symmetrically distributed about the central axis of the protective cover. The limiting rod and the base are slidably connected, and two sets of limiting rods are provided, and the limiting rods are symmetrically distributed about the central axis of the base.

[0015] Preferably, the trigger head is hemispherical, and the second reset spring is used to compress the limiting rod and keep it moving inward.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of a drive rod, an extension rod, and a thrust bearing, enables the device to prevent the strip from shifting beyond its height by installing an extension rod at the bottom of the drive rod. This avoids the strip scratching the drive rod. Furthermore, by installing a thrust bearing and a protective disc on the outside of the extension rod, when the strip deviates and impacts the protective disc, the disc rotates in the same direction as the strip, changing sliding friction into rolling friction and significantly reducing the scratching force on the extension rod. This achieves the purpose of facilitating the protection of the drive rod by the device.

[0017] This invention, through the combination of a support rod, an oil reservoir, and an oil-impregnated felt, enables the device to fill the oil reservoir with lubricating oil and then apply the lubricating oil to the protective disc via the oil-impregnated felt. This results in an oil film on the surface of the protective disc, which serves to prevent rust and reduce scratches. When the protective disc is rotated by the strip steel, it comes into contact with the oil-impregnated felt, thus completing the oiling process. A first return spring provides a restoring force to the oil reservoir, ensuring that the oil-impregnated felt remains in contact with the protective disc, thereby improving the oiling efficiency and ultimately enhancing the wear resistance of the protective disc.

[0018] This invention, through the combination of a protective cover, guide groove, and limiting hole, enables the device to slide the protective cover into the base. As the protective cover slides towards the base, the guide groove contacts the trigger head, and the guide groove presses against the trigger head and the limiting rod, causing the limiting rod to move outward. After the limiting rod and the trigger head are aligned with the limiting hole, the restoring force of the second reset spring resets the limiting rod, allowing it to insert into the limiting hole. This, in turn, limits the protective cover, enabling it to protect the oil reservoir and prevent dust and impurities from entering its interior. This achieves the purpose of facilitating dust prevention and protection of the oil reservoir. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, the present invention provides an inlet clamping mechanism for a mixed-wire welding machine. A positioning sleeve 2 is installed at the bottom end of the hydraulic cylinder 1, and a mounting base 3 is fixed at the bottom end of the positioning sleeve 2. An upper clamp 4 is fixed to the outside of the mounting base 3. A protective mechanism 5 is installed at the bottom end of the hydraulic cylinder 1, and a base 6 is provided at the bottom end of the protective mechanism 5. A lower clamp 7 is fixed to the outside of the base 6. An oiling mechanism 8 is installed at the top end of the base 6, and a disassembly and assembly mechanism 9 is installed on the outside of the base 6.

[0023] like Figures 1 to 6 As shown, the protective mechanism 5 includes a drive rod 501, an extension rod 502, and a thrust bearing 503. The drive rod 501 is fixed to the extension end of the hydraulic cylinder 1. The extension rod 502 is welded to the bottom end of the drive rod 501. The thrust bearing 503 is fixed to the outside of the extension rod 502. The protective disc 504 is fixed to the outside of the thrust bearing 503. There are two sets of drive rods 501 and extension rods 502. The drive rods 501 and extension rods 502 are symmetrically distributed about the central axis of the base 6. The extension rod 502 is fixed to the inner ring of the thrust bearing 503. The protective disc 504 is fixed to the outer ring of the thrust bearing 503. There are two sets of thrust bearings 503. The thrust bearings 503 are symmetrically distributed about the central axis of the extension rod 502.

[0024] The above solution employs the following: By installing an extension rod 502 at the bottom of the drive rod 501, the height of the strip when its position deviates will not exceed the height of the extension rod 502, thus preventing the strip from scratching the drive rod 501. Furthermore, by installing a thrust bearing 503 and a protective disc 504 on the outside of the extension rod 502, when the strip deviates and impacts the protective disc 504, the protective disc 504 will rotate in the direction of contact with the strip, changing sliding friction into rolling friction, significantly reducing the scratching force on the extension rod 502. Simultaneously, the edges of the protective disc 504 are rounded to prevent the strip from getting stuck. In addition, the two sets of symmetrically distributed drive rods 501 and extension rods 502 can form double protection from both sides of the strip, further reducing the probability of the strip contacting the drive rod 501 when it deviates. The two sets of thrust bearings 503 symmetrically distributed about the central axis of the extension rod 502 can make the protective disc 504 more stable during rotation, reducing swaying caused by uneven force.

[0025] like Figures 1 to 7 As shown, the oiling mechanism 8 includes a support rod 801, an oil reservoir 802, and an oil-impregnated felt 803. The support rod 801 is fixed to the top of the base 6. The oil reservoir 802 is sleeved on the outside of the support rod 801. The oil-impregnated felt 803 is connected to the outside of the oil reservoir 802. There are two sets of support rods 801. The support rods 801 are symmetrically distributed about the central axis of the base 6. The inner wall of the oil reservoir 802 is attached to the outer wall of the support rod 801. The oil reservoir 802 and the support rod 801 are rotatably connected. The outside of the oil-impregnated felt 803 is connected to the protective disc 504.

[0026] like Figures 1 to 7 As shown, the oil-impregnated felt 803 is provided with limiting magnetic blocks 804 on its exterior. There are four sets of limiting magnetic blocks 804, which are arranged in an array. The inner wall of the oil storage cylinder 802 is made of iron. The limiting magnetic blocks 804 and the inner wall of the oil storage cylinder 802 are magnetically connected. The support rod 801 is fixed with a first return spring 805 on its exterior. The top of the base 6 is provided with a recycling trough 806. The top of the base 6 is fixed with a delivery pump 807. The bottom of the delivery pump 807 is connected to a first delivery pipe 808. The top of the delivery pump 807 is connected to a second delivery pipe 809. The bottom of the first return spring 805 is fixed with the oil storage cylinder 802. The first return spring 805 is used to squeeze the first return spring 805 and keep it rotating. The bottom of the recycling trough 806 is provided with an inclined surface. The output end of the first delivery pipe 808 is connected to the oil storage cylinder 802.

[0027] The above solution involves filling the oil reservoir 802 with lubricating oil and then using an oil-impregnated felt 803 to draw the oil and apply it to the protective disc 504. This creates an oil film on the surface of the protective disc 504, preventing rust and reducing scratches. When the protective disc 504 rotates due to the steel strip, it contacts the oil-impregnated felt 803, thus completing the oiling process. A first return spring 805 provides a restoring force to the oil reservoir 802, ensuring that the oil-impregnated felt 803 remains in contact with the protective disc 504, thereby improving the oiling efficiency. To improve efficiency, when the oil-impregnated felt 803 needs replacement after long-term use, the limiting magnetic block 804 is removed, and the oil-impregnated felt 803 is replaced. The limiting magnetic block 804 and the oil storage cylinder 802 are then used to magnetically fix the oil-impregnated felt 803 back in place. Furthermore, by setting up a recovery tank 806, when the oil-impregnated felt 803 applies lubricating oil to the protective disc 504, excess lubricating oil flows into the recovery tank 806 and then to the bottom of the first conveying pipe 808. The recovery tank 806... When excessive lubricating oil is collected, the delivery pump 807 is activated, and the collected lubricating oil is recovered into the oil reservoir 802 through the first delivery pipe 808 and the second delivery pipe 809. Furthermore, four sets of arrayed limiting magnetic blocks 804 can fix the oil-impregnated felt 803 from multiple angles, ensuring the stability of its connection with the oil reservoir 802 and preventing displacement when the protective disc 504 rotates, thus ensuring the continuity of the oiling process. The design of the oil reservoir 802 rotating with the support rod 801 allows the oil reservoir 802 to move with the protective disc 504. Slightly adjusting the rotation direction of 04 allows for better contact between the oil-soaked felt 803 and the protective disc 504, improving the uniformity of oil application. The sloping design at the bottom of the recovery tank 806 guides excess lubricating oil to flow quickly to the bottom of the first conveying pipe 808, reducing lubricating oil residue in the recovery tank 806. The circulation system composed of the conveying pump 807, the first conveying pipe 808, and the second conveying pipe 809 enables the reuse of lubricating oil, reducing the cost of lubricating oil consumption and avoiding environmental pollution caused by lubricating oil waste.

[0028] like Figures 1 to 8 As shown, the disassembly and assembly mechanism 9 includes a protective cover 901, a guide groove 902, and a limiting hole 903. The protective cover 901 is movably connected to the outside of the base 6. One end of the protective cover 901 is provided with a guide groove 902. There are two sets of protective covers 901. The protective covers 901 are symmetrically distributed about the central axis of the base 6. The outer wall of the protective cover 901 is attached to the inner wall of the base 6. The protective cover 901 and the base 6 are slidably connected. The guide groove 902 is an inclined surface.

[0029] like Figures 1 to 8As shown, the protective cover 901 has a limiting hole 903 on its exterior, and the base 6 has a limiting rod 904 movably connected inside. There are two sets of limiting holes 903, which are symmetrically distributed about the central axis of the protective cover 901. The limiting rod 904 and the base 6 are slidably connected. There are two sets of limiting rods 904, which are symmetrically distributed about the central axis of the base 6. One end of the limiting rod 904 is fixed with a trigger head 905. A second return spring 906 is installed on the exterior of the limiting rod 904. The trigger head 905 is hemispherical. The second return spring 906 is used to squeeze the limiting rod 904 and keep it moving inward.

[0030] The above solution involves sliding the protective cover 901 into the interior of the base 6. As the protective cover 901 slides towards the base 6, the guide groove 902 contacts the trigger head 905, and the guide groove 902 presses against the trigger head 905 and the limiting rod 904, causing the limiting rod 904 to move outward. After the limiting rod 904 and the trigger head 905 are aligned with the limiting hole 903, the restoring force of the second return spring 906 resets the limiting rod 904, allowing it to insert into the limiting hole 903. This, in turn, limits the protective cover 901, enabling it to protect the oil reservoir 802. To prevent dust and impurities from entering the oil reservoir 802, when the protective cover 901 needs to be removed to replenish the lubricating oil inside the oil reservoir 802, the limiting rod 904 is pulled to disengage from the limiting hole 903. Since there are two sets of limiting rods 904, two people are required to remove one set of protective cover 901. This not only ensures the stable installation of the protective cover 901, but also forms a safety interlock logic through the "two-person operation mechanism". When it is necessary to remove the protective cover 901, two people must pull the limiting rod 904 at the same time, and only one person can interactively remove the protective cover 901. This design avoids the randomness of single-person operation.

[0031] The working principle and usage process of this invention are as follows: By setting an extension rod 502 at the bottom end of the drive rod 501, the height of the strip when its position deviates will not exceed the height of the extension rod 502, thereby preventing the strip from scratching the drive rod 501. Furthermore, by installing a thrust bearing 503 and a protective disc 504 on the outside of the extension rod 502, when the strip deviates and impacts the protective disc 504, the protective disc 504 will rotate in the contact direction of the strip, changing sliding friction into rolling friction, significantly reducing the scratching force on the extension rod 502. Simultaneously, the edges of the protective disc 504 are rounded to prevent the strip from getting stuck. Lubricating oil is filled inside the oil reservoir 802, and the lubricating oil is absorbed and applied to the protective disc 504 through the oil-impregnated felt 803, ensuring the surface of the protective disc 504 is protected. The protective disc 504 is coated with an oil film, which serves to prevent rust and reduce scratches. When the protective disc 504 is rotated by the strip steel, it comes into contact with the oil-impregnated felt 803, thus completing the oiling process. A first return spring 805 provides a restoring force to the oil reservoir 802, ensuring that the oil-impregnated felt 803 remains in contact with the protective disc 504, thereby improving oiling efficiency. When the oil-impregnated felt 803 needs replacement after long-term use, the limiting magnetic block 804 is removed, and the oil-impregnated felt 803 is replaced. The magnetic properties of the limiting magnetic block 804 and the inside of the oil reservoir 802 then re-fix the oil-impregnated felt 803, allowing for replacement. A recovery trough 806 ensures that when the oil-impregnated felt 803 applies lubricating oil to the protective disc 504... Excess lubricating oil flows into the recovery tank 806 and to the bottom of the first conveying pipe 808. When too much lubricating oil is collected in the recovery tank 806, the conveying pump 807 is activated, and the collected lubricating oil is recovered into the oil storage tank 802 through the first conveying pipe 808 and the second conveying pipe 809. By sliding the protective cover 901 to the inside of the base 6, when the protective cover 901 slides towards the base 6, the guide groove 902 contacts the trigger head 905, and the guide groove 902 presses the trigger head 905 and the limiting rod 904, causing the limiting rod 904 to move outward. After the positions of the limiting rod 904 and the trigger head 905 are aligned with the limiting hole 903, the restoring force of the second return spring 906 resets the limiting rod 904, so that the limiting rod 904... 4. Insert the limit rod 904 into the limiting hole 903, thereby limiting the protective cover 901. This allows the protective cover 901 to protect the oil reservoir 802, preventing dust and impurities from entering. When it is necessary to remove the protective cover 901 to replenish the lubricating oil inside the oil reservoir 802, pull the limiting rod 904 to disengage it from the limiting hole 903. Since there are two sets of limiting rods 904, two people are required to remove one set of protective covers 901. This not only ensures the stable installation of the protective cover 901 but also forms a safety interlock logic through a "two-person operation mechanism." When it is necessary to remove the protective cover 901, both people must pull the limiting rod 904 simultaneously, and only one person can interactively remove the protective cover 901.This design avoids the randomness of single-person operation.
