Description

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for processing support frames. Background Technology

[0002] The term "hydraulic cylinder safety support" actually refers to a special type of support device that plays a safety role in hydraulic systems. It can be understood as the "safety officer" of the hydraulic system—unnoticed most of the time, but immediately stepping in to prevent heavy objects from falling or equipment from overturning, ensuring the safety of personnel and equipment should the hydraulic system fail or an accident occur.

[0003] However, in practical applications, some unresolved issues remain. The following are some common problems with welding equipment used in support frame processing: Safety supports typically require high precision in fitting (such as shaft-hole fits and sleeve sliding fits). Welding deformation can directly cause moving parts to jam, rendering the safety function ineffective. Furthermore, arc welding generates a large heating zone, leading to increased workpiece deformation, affecting the production of safety supports, and increasing their cost. Summary of the Invention

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention, which provides a welding device for processing support frames, particularly suitable for the automated welding of precision support frames such as safety brackets that are sensitive to welding heat and easily deformed. The welding device for processing support frames includes a base 1, a support platform 2, a main unit 3, a telescopic component 4, a welding torch 5, a feed component 6, a rotary belt 7, and a transmission component 8. Through an integrated hydraulic drive system, the device simultaneously drives the rotary belt 7 within the feed component 6 while controlling the welding torch 5 to perform welding. This achieves automatic feeding of the workpiece (safety bracket) and instant cooling of the welding area, effectively solving the problem of workpiece deformation caused by welding heat input and improving the processing accuracy and yield of safety brackets.

[0031] Specifically, the base 1 is fixedly mounted on the welding station, providing stable support for the entire device. The top of the base 1 has a working groove for accommodating and positioning the workpiece to be processed.

[0032] The working groove is rotatably connected with a baffle for abutting the workpiece, and a spring that can rebound is also provided at the rotating shaft. When the safety bracket is placed in the working groove, the baffle abuts the safety bracket to achieve the effect of centering the workpiece.

[0033] Support platform 2, which is bolted into the working groove, is used to place and support workpieces such as security brackets. The height of support platform 2 can be adjusted according to the size of the workpiece to ensure accurate welding position.

[0034] To reduce resistance during workpiece feeding, rollers are installed on the top of the support platform 2. In order to reduce maintenance costs, the rollers should be installed on both sides of the weld of the safety bracket.

[0035] The main unit 3 is fixed to the top of the base 1 by a column and has an integrated hydraulic control system that provides power to the various actuators of the device.

[0036] Telescopic components 4 are located on both sides of the bottom of the main unit 3 and are arranged symmetrically from left to right. Telescopic components 4 can move up and down under hydraulic drive.

[0037] The welding torch 5 is connected between two telescopic components 4 and moves synchronously with the raising and lowering of the telescopic components 4. The welding torch 5 is used to weld workpieces using methods such as gas shielded welding or argon arc welding.

[0038] The feed component 6 is fixed to the bottom of the telescopic component 4 and moves up and down together with the telescopic component 4. The feed component 6 is equipped with a rotary belt 7 that can rotate.

[0039] The rotary belt 7, located within the feed component 6, is used to contact the workpiece surface during the welding process. The rotation of the rotary belt 7 automatically feeds the workpiece along the welding direction, and it also has heat conduction and dissipation functions, enabling immediate cooling of the welding area.

[0040] The transmission component 8, which is connected to one side of the feed component 6, is used to receive hydraulic oil from the telescopic component 4 and convert hydraulic energy into mechanical energy to drive the rotary belt 7 to move.

[0041] The telescopic component 4, transmission component 8, and rotary belt 7 are sequentially connected via conduits to form a closed hydraulic channel for driving the rotary belt 7. This design utilizes the same hydraulic source to automatically trigger and drive the workpiece feeding and cooling system while driving the welding torch 5 to press down and contact the workpiece. This achieves coordinated linkage of the three major functions of welding, feeding, and cooling, eliminating the need for additional independent drive sources and control units. The structure is compact and the control is precise.

[0042] Among these options, using phenyl silicone oil (such as Wacker AP500 or IOTABJ200) is currently the most direct and reliable solution for hydraulic fluid. It possesses the fundamental qualities of a hydraulic fluid—suitable viscosity, chemical inertness, and low compressibility—enabling reliable pressure transmission. Simultaneously, it can also be used as a heat transfer oil, effectively absorbing and transferring heat within the system to meet thermal conductivity requirements.

[0043] The hydraulic control system, welding torch 5 and its related circuit connections mentioned above are existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0044] Example 2, refer to Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, the telescopic component 4 includes a sleeve 41 and a sliding rod 42. The sleeve 41 is fixedly connected to the bottom of the main unit 3; an oil inlet pipe 9 is connected to the top of the sleeve 41 for introducing high-pressure hydraulic oil. The sliding rod 42 is slidably connected inside the sleeve 41 and can move axially along the sleeve 41 under hydraulic drive; the bottom of the sliding rod 42 extends out of the sleeve 41 and is fixedly connected to the feed component 6 to drive the feed component 6 and the welding torch 5 to rise and fall. A mounting bracket 10 for mounting the welding torch 5 is fixedly connected to the bottom side wall of the sliding rod 42.

[0046] The top of the slide rod 42 has a groove 11, which is a blind hole. The bottom of the outer wall of the slide rod 42 has an oil outlet 12 communicating with the groove 11. The bottom of the groove 11 is connected by a spring to a valve core 13 for blocking the oil outlet 12. Initially, the valve core 13 is positioned above the groove 11 under the action of the spring, blocking the oil outlet 12 and preventing hydraulic oil from flowing out.

[0047] A circular groove 14 is provided on the top of the valve core 13 to receive hydraulic oil from the inlet pipe 9. A through groove 15, communicating with the circular groove 14, is provided on the bottom side wall of the valve core 13 corresponding to the oil outlet 12. When the valve core 13 is subjected to sufficient hydraulic pressure to overcome the spring force and move downward, the through groove 15 is aligned with the oil outlet 12, thereby opening the oil circuit and allowing hydraulic oil to flow into the subsequent transmission component 8. This design constitutes a pressure-triggered automatic oil circuit switch, ensuring that the feeding and cooling functions are activated only after the welding torch 5 is pressed down and the workpiece is clamped, thus ensuring the correct timing of the welding process.

[0048] The transmission component 8 includes a cylinder body 81, a rotor 82, and blades 83. The cylinder body 81 is fixedly connected to one side of the feed component 6; the side wall of the cylinder body 81 has an oil inlet 16 and an oil outlet 17 sequentially formed from top to bottom, with the oil outlet 12 connected to the oil inlet 16 via a pipeline. The rotor 82 is eccentrically positioned inside the cylinder body 81 near the oil inlet 16, forming a crescent-shaped working chamber with variable volume. Multiple slots 18 are spaced apart on the circumferential side of the rotor 82; the blades 83 are slidably connected within the slots 18 by springs, maintaining tight contact with the inner wall of the cylinder body 81 at all times.

[0049] When hydraulic oil enters the cylinder 81 through inlet 16, the pressurized oil pushes the vanes 83. Due to the eccentric arrangement of the rotor 82, the volume between each vane 83 changes, thereby driving the rotor 82 to rotate. This process converts the pressure energy of the hydraulic oil into the rotational mechanical energy of the rotor 82. The hydraulic oil flowing around the rotor 82 is finally discharged from outlet 17 and enters the next cycle.

[0050] Example 3, referring to Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the feed component 6 includes a housing 61 and a support block 62. The housing 61, fixedly connected to the slide rod 42, serves as the support frame for the entire feed assembly. The support block 62, fixedly connected inside the housing 61, is a stationary component. A rotating belt 7, which can rotate around the outer wall of the support block 62, is fitted around its outer wall. A notch is provided at the bottom of the support block 62 to form a cooling chamber 19 for containing cooling medium between the support block 62 and the inner wall of the rotating belt 7. Oil inlets 20 and 21, respectively, communicating with the cooling chamber 19, are provided on both sides of the support block 62. Oil inlet 20 communicates with oil outlet 17 of the transmission component 8 to receive hydraulic oil that has completed its driving operation; oil outlet 21 returns the hydraulic oil that has absorbed heat to the hydraulic system for cooling and circulation via the return pipe 28.

[0052] Chains 22 are provided on both sides of the rotary belt 7, and sprockets 23 are engaged on both sides of the chains 22. One sprocket 23 is fixedly connected to the rotor 82 of the transmission component 8 via a connecting shaft. When the rotor 82 rotates, it drives the sprocket 23 to rotate through the connecting shaft, and the sprocket 23 in turn drives the chain 22 and the entire rotary belt 7 to rotate on the support block 62. The bottom surface of the rotary belt 7 contacts the surface of the workpiece placed on the support table 2, and the workpiece is driven to feed linearly along the welding direction by friction.

[0053] Example 4, refer to Figures 5-7 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0054] Specifically, the rotating belt 7 has multiple heat-conducting blocks 24 spaced along its circumference that contact the cooling cavity 19. The heat-conducting blocks 24 are made of a metal material with excellent thermal conductivity (such as copper or aluminum alloy). One side is embedded in the rotating belt 7 and contacts the medium inside the cooling cavity 19, while the other side contacts the workpiece. Flexible sealing strips 25 are fixedly connected to the inner wall of the rotating belt 7 on both sides of the heat-conducting blocks 24. The sealing strips 25 slide and seal against the outer wall of the support block 62, preventing hydraulic oil leakage from the cooling cavity 19 and ensuring that the hydraulic oil must flow over the surface of the heat-conducting blocks 24 to flow from the inlet 20 to the outlet 21, thus guaranteeing heat exchange efficiency.

[0055] The width of the heat-conducting block 24 gradually decreases from the inside to the outside, making its cross-section an isosceles trapezoid. Heat-conducting plates 26, which can slide along the inclined plane of the trapezoid, are slidably connected to both sides of the heat-conducting block 24. Spring tabs 27 are fixedly connected between the sidewalls of the heat-conducting plates 26 and the rotating belt 7. In the initial state, the heat-conducting plates 26 partially extend beyond the side of the heat-conducting block 24 under the action of the spring tabs 27.

[0056] When the rotating belt 7 moves and brings the heat-conducting block 24 into contact with the workpiece, the heat-conducting plates 26 on both sides are forced to slide inward along the trapezoidal slope under the contact pressure, compressing the spring 27. At this time, the bottom surfaces of the heat-conducting block 24 and the two heat-conducting plates 26 together form a flat and continuous contact surface, greatly expanding the actual contact area with the workpiece, thereby significantly improving the efficiency of heat absorption from the workpiece (welding heat-affected zone). When the heat-conducting block 24 continues to move with the rotating belt 7 and separates from the workpiece, the contact pressure disappears, the spring 27 resets, and pushes the heat-conducting plate 26 to slide out along the slope again, returning to the initial state. Because the heat-conducting block 24 is trapezoidal, the gap between two adjacent heat-conducting blocks 24 will increase after the heat-conducting plate 26 resets, which can effectively prevent the heat-conducting plates 26 from interfering with each other or getting stuck at the rotation and bending parts of the rotating belt 7, ensuring the smooth operation of the rotating belt 7.

[0057] Example 5, refer to Figures 3-5 This is the fifth embodiment of the present invention, which is based on the previous four embodiments.

[0058] Specifically, oil outlet 12 (from the slide rod 42 of the telescopic component 4) and oil outlet 17 (from the cylinder 81 of the transmission component 8) are respectively connected to the corresponding oil inlet 16 (transmission component 8) and oil inlet 20 (cooling chamber 19 of the feed component 6) through pipelines. Oil outlet 21 (the liquid outlet of the cooling chamber 19) is fixedly connected to a return oil pipe 28, and the end of the return oil pipe 28 is connected to the hydraulic oil tank in the main unit 3, forming a complete oil circuit circulation: hydraulic pump → telescopic component 4 → transmission component 8 → cooling chamber 19 → return oil tank.

[0059] In use, the security bracket workpiece to be welded is accurately placed on the support platform 2 in the working groove of the base 1 and its position is adjusted. Then, the hydraulic system is started, and high-pressure hydraulic oil is injected into the sleeve 41 of the telescopic component 4 through the oil inlet pipe 9.

[0060] The hydraulic oil first pushes the piston inside the sleeve 41 downward, thereby driving the slide rod 42, welding torch 5, feed piece 6 and rotary belt 7 to descend as a whole. When the heat-conducting block 24 at the bottom of the rotary belt 7 contacts the surface of the safety bracket and applies a certain clamping force, the welding torch 5 also descends to the preset welding height.

[0061] At this point, because the rotary belt 7 is blocked by the workpiece, the feed piece 6 cannot continue to descend, causing the hydraulic pressure inside the sleeve 41 to continuously increase. The increased hydraulic pressure acts on the circular groove 14 at the top of the valve core 13, pushing the valve core 13 to slide down in the slide groove 11 against the spring force. When the valve core 13 moves down to the point where the through groove 15 aligns with the oil outlet 12, the oil circuit is opened. High-pressure hydraulic oil then continuously enters the oil inlet 16 of the transmission piece 8 through the oil outlet 12 and the pipeline.

[0062] After the hydraulic oil enters the cylinder 81, it pushes the vanes 83, which in turn drives the eccentrically mounted rotor 82 to rotate. The rotor 82 drives the sprocket 23, which is fixed to it, to rotate via the connecting shaft. The sprocket 23 drives the chain 22 and the entire rotary belt 7 to begin rotating. The friction between the rotary belt 7 and the workpiece surface drives the safety bracket to feed at a constant speed along the welding direction, thus achieving a coordinated operation of welding and automatic feeding simultaneously.

[0063] Meanwhile, the hydraulic oil that completes the driving operation flows out from the oil outlet 17 of the transmission component 8, enters the oil inlet 20 of the feed component 6 through the pipeline, and flows into the cooling chamber 19. Inside the cooling chamber 19, the hydraulic oil comes into full contact with the heat-conducting blocks 24 embedded in the inner wall of the rotating belt 7, efficiently carrying away the heat absorbed by the heat-conducting blocks 24 from the workpiece welding area. The hydraulic oil that has absorbed heat finally flows back to the oil tank of the main unit 3 from the oil outlet 21 through the return pipe 28, and re-enters the circulation after cooling.

[0064] During the movement of the rotating belt 7, when the heat-conducting block 24 moves with the rotating belt 7 to the position of contact with the workpiece, under the action of contact pressure, the heat-conducting plates 26 on both sides of the heat-conducting block 24 are pressed and slide inward along the trapezoidal inclined plane. Their bottom surfaces are flush with the bottom surfaces of the heat-conducting block 24, forming a flat and enlarged contact surface, which greatly increases the contact area with the workpiece, thereby significantly improving the heat dissipation effect on the welding heat-affected zone, effectively suppressing the local overheating and thermal stress caused by welding heat, and fundamentally avoiding welding deformation of the safety support. As the rotating belt 7 continues to move, when the heat-conducting block 24 separates from the workpiece, the contact pressure disappears, and the heat-conducting plates 26 are pushed back and slide out along the inclined plane by the spring plate 27. Due to the isosceles trapezoidal design of the heat-conducting block 24, the gap between adjacent heat-conducting blocks 24 increases after resetting, ensuring that the heat-conducting plates 26 will not collide with each other when passing around the end sprocket 23 of the rotating belt 7, ensuring the smooth rotation and long-term stable operation of the rotating belt 7.

[0065] Throughout the welding process, the welding torch 5 achieves continuous and automated welding operations. After welding is completed, the hydraulic system is depressurized, the slide bar 42 rises under the action of the return spring, driving the welding torch 5 and the feed piece 6 to reset. The valve core 13 re-seals the oil outlet 12 under the action of the spring, and the device stops operating, waiting for the next cycle. Through the above design, this device highly integrates the functions of workpiece clamping, welding, feeding, and forced cooling, achieving precise coordination of multiple processes with a single hydraulic system, significantly improving the welding quality and production efficiency of precision support frames such as safety brackets.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
