Cooling equipment for welding metal building materials

Abstract

The present invention relates to the technical field of welding equipment, and specifically discloses a cooling device for welding metal building materials. The cooling device for welding metal building materials achieves the purpose of cooling the workpiece and performing gas protection during welding. The heat dissipation device dissipates heat generated inside the welding device, thereby stabilizing the working state of the welding device and facilitating long-term work. The gas is introduced into the surface of the workpiece through the pipeline design of the heat dissipation device, thereby quickly cooling the welded workpiece. Since the heat is transferred through the surface of the welding device and the temperature is increased, the temperature difference between the gas temperature and the workpiece is reduced, thereby avoiding embrittlement of the workpiece due to excessive cooling. The heat dissipation device blows the workpiece surface in a targeted manner, thereby reducing the use of nitrogen compared to traditional gas protection methods. The fixing device self-locks and fixes the workpiece, thereby preventing welding errors caused by shaking of the workpiece during welding.

Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to a cooling device for welding metal building materials. Background Art

[0002] In the field of metal building material welding, the cooling process is a key link that determines the welding quality and structural performance. Traditional cooling technology mainly relies on passive methods such as natural cooling, water cooling or air cooling, and its limitations are becoming increasingly prominent. Although natural cooling is simple to operate, the cooling rate is uncontrollable, which can easily lead to thermal stress gradients between the welding area and the base material, thereby causing defects such as deformation and cracks. Especially in the welding of high-strength steel or aluminum alloys, slow cooling may induce brittle phase transformation. Although water cooling can accelerate cooling, sudden cooling can easily cause local embrittlement of the material, and the cooling uniformity is poor, making it difficult to adapt to complex weld geometries. There is also a waste of water resources and the risk of rust. Air cooling technology improves efficiency through forced convection, but uneven distribution of ambient temperature, humidity and airflow may lead to insufficient cooling stability, making it difficult to achieve precise temperature control.

[0003] Current welding equipment usually uses natural cooling or water cooling for cooling. Natural cooling is too slow, and water cooling can easily cause large temperature changes in the workpiece, leading to embrittlement of the material. Summary of the Invention

[0012] The present invention provides a cooling device for welding metal building materials. It has the following beneficial effects:

[0013] 1. The cooling device for welding metal building materials is provided with an introduction device. The introduction device drives vaporized nitrogen through a ventilation pipe into the interior of the heat dissipation housing, allowing the nitrogen to pass through the side of the welding device to cool the entire side of the welding device. The heat is transferred to the arc-shaped phase change box. The heat heats the liquid inside the arc-shaped phase change box, which is heated to gas. The gas is transferred to the side of the piston rod through the piston tube. The gas pressure pushes the piston rod along the inside of the piston tube, and the piston rod drives the restriction shell to move. The movement of the restriction shell compresses the spring of the spring slide, thereby increasing the relative area between the side of the restriction shell and the sealing plate, thereby increasing the gas flow rate, thereby accelerating the heat dissipation rate of a specific area on the side of the welding device, thereby helping to cool the side of the welding device. When the temperature in the specific area drops, the gas inside the arc-shaped phase change box turns back into liquid, and the spring of the spring slide releases the elastic force, driving the restriction shell to return to a closed state, thereby reducing the nitrogen flow rate in the specific area. At this time, the nitrogen flows to other areas with higher heat generation, thereby achieving different heat dissipation rates for different areas while keeping the overall flow rate unchanged. After cooling, the nitrogen is guided to provide gas protection for the workpiece surface.

[0014] 2. The cooling equipment for welding metal building materials is provided with a side of a spring limit rod which is placed inside the air guide housing. The spring limit rod limits the nitrogen storage tank, and the nitrogen flows through the inner wall of the hollow fan. The first motor is started, and the driving shaft of the first motor drives the hollow fan to rotate, so that the nitrogen is accelerated and becomes gas. The nitrogen gradually heats up when passing through the surface of the welding device and reaches the inside of the down-pressure shell through the gas pipe. When welding is performed, the moving device drives the heat dissipation shell to descend, and the heat dissipation shell drives the down-pressure shell to stick to the surface of the workpiece, thereby fixing the workpiece, and the nitrogen enters the air inlet pipe and the inside of the down-pressure shell through the gas pipe, and is released from the air outlet. The positioning groove fixes the surface of the workpiece. The angle of the positioning groove has a certain limiting effect on workpieces of different shapes under the downward pressure of the first spring rod. The gas is released through the air outlet and flows along the surface of the workpiece. During welding, the welding position is directly and directionally protected by gas and the welding position is directly cooled after welding is completed. The gas protection and cooling of the welding position are realized, and the position is limited. At the same time, the gas reduces the temperature difference by cooling the welding device, thereby avoiding the embrittlement caused by excessive cooling speed of the workpiece surface, and reducing the probability of embrittlement compared with water cooling.

[0015] 3. This cooling equipment for welding metal building materials is equipped with a support base. The weight of the workpiece drives the support base to descend, which in turn drives the arc-shaped sliding ring downward. The downward movement of the arc-shaped sliding ring drives the connecting rod downward. The downward rotation of the connecting rod drives the clamping bracket downward, which in turn drives the clamping base plate downward. The downward rotation of the clamping base plate drives the second hydraulic rod downward to clamp and position the workpiece, thereby limiting the workpiece surface. Due to the weight of the workpiece and the different volumes of the first hydraulic sleeve and the second hydraulic rod, the workpiece is stably clamped on the surface of the support base. The L-shaped bracket at the movable end of the second hydraulic rod is adjusted to a certain angle, allowing the L-shaped bracket to adapt to workpiece surfaces of different shapes, thereby clamping workpieces of different shapes. When the workpiece is removed from the support base after welding, the support base is no longer subject to the weight of the workpiece, thereby releasing the hydraulic oil from the first hydraulic sleeve and the second hydraulic rod, thereby releasing the workpiece. This achieves the function of self-locking the workpiece during welding, which is beneficial for maintaining a stable state during welding and facilitating welding.

[0016] 4. The cooling equipment for welding metal building materials is provided with an adjusting bolt. The adjusting bolt is manually rotated, and the adjusting bolt rotates at the bottom of the adjusting frame, thereby driving the adjusting sleeve to rotate through the thread. The adjusting sleeve rises or falls on the side of the adjusting bolt, thereby changing the amount of descent of the movable end of the first hydraulic sleeve, so that the second hydraulic rod produces different deformation amounts, thereby clamping workpieces of different diameters, thereby performing self-locking clamping on workpieces of different diameters, thereby improving the versatility of the equipment.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 3 The present invention provides a technical solution: a cooling device for welding metal building materials, comprising a base plate bracket 1, a moving device 2 is fixedly connected to the top of the base plate bracket 1, a heat dissipation device 3 is fixedly connected to the side of the moving device 2, a welding device 4 is fixedly connected to the inner wall of the heat dissipation device 3, and a fixing device 5 is fixedly connected to the side of the moving device 2, and the fixing device 5 is arranged below the welding device 4.

[0028] The base plate bracket 1 supports the equipment as a whole, and the moving device 2 moves the heat dissipation device 3 in multiple directions to meet different welding requirements. The heat dissipation device 3 drives the welding device 4 to move. The heat dissipation device 3 dissipates the heat generated inside the welding device 4, thereby stabilizing the working state of the welding device 4 and facilitating long-term work. The gas is introduced into the surface of the workpiece through the pipeline design of the heat dissipation device 3. In addition to gas protection of the surface of the workpiece during welding, the heat of the workpiece surface can also be taken away by pneumatic means, thereby quickly cooling the welded workpiece. Moreover, since the heat is transferred through the surface of the welding device 4, the temperature rises, thereby reducing the temperature difference between the gas temperature and the workpiece, thereby avoiding embrittlement of the workpiece caused by excessive cooling. At the same time, the gas can blow away dust and welding slag when passing through the surface of the workpiece, thereby avoiding welding errors caused by untimely cleaning of impurities and welding slag. At the same time, the targeted blowing of the heat dissipation device 3 on the workpiece surface reduces the use of nitrogen compared to the traditional gas protection method, thereby reducing nitrogen consumption. The fixing device 5 self-locks the workpiece and uses the weight of the workpiece to self-lock the workpiece, thereby preventing welding errors caused by shaking of the workpiece during welding.

[0029] The heat dissipation device 3 includes a heat dissipation shell 301, the inner wall of the heat dissipation shell 301 is fixedly connected to a heat dissipation blade 302, the top of the heat dissipation blade 302 passes through and is fixedly connected to a ventilation pipe 303, the side of the ventilation pipe 303 is fixedly connected to a variable flow component 304, the top of the ventilation pipe 303 is connected to a gas introduction device 305, the bottom of the heat dissipation shell 301 is fixedly connected to the fixed end of the first spring rod 306, the movable end of the first spring rod 306 is fixedly connected to the downward pressure component 307, the bottom of the heat dissipation shell 301 is connected to an air supply pipe 308, and the end of the air supply pipe 308 away from the heat dissipation shell 301 is connected to the top of the downward pressure component 307.

[0030] The variable flow assembly 304 includes a fixed frame 3041, the inner wall of the fixed frame 3041 is fixedly connected to a first slide 3042, the top of the first slide 3042 is fixedly connected to a fixed plate 3043, the side of the fixed plate 3043 is fixedly connected to a spring slide 3044, the side of the fixed frame 3041 is sleeved and slidably connected to a limiting shell 3045, the inner wall of the fixed frame 3041 is fixedly connected to a sealing plate 3046 adapted to the limiting shell 3045, and the fixed frame 3041 is fixedly connected to the inner wall of the fixed frame 3041. The side of 041 is fixedly connected to a piston tube 3047, and the inner wall of the piston tube 3047 is slidably connected to a piston rod 3048. The piston rod 3048 passes through the side of the fixed frame 3041 and is fixedly connected to the side of the limiting shell 3045. The end of the piston tube 3047 away from the fixed frame 3041 is connected to an arc-shaped phase change box 3049. The side of the arc-shaped phase change box 3049 is fixedly connected to the side of the welding device 4, and the side of the fixed frame 3041 is connected to the side of the ventilation pipe 303.

[0031] The gas introduction device 305 is started, and the gas introduction device 305 drives the gasified nitrogen to enter the interior of the heat dissipation housing 301 through the ventilation pipe 303, so that the nitrogen passes through the side of the welding device 4, thereby cooling the side of the welding device 4 as a whole. A through hole is directly opened at the bottom of the ventilation pipe 303, so that the area of the welding device 4 with higher heat generation always maintains gas cooling. When different areas of the welding device 4 generate different amounts of heat, the heat is transferred to the arc-shaped phase change box 3049, and the heat heats the liquid inside the arc-shaped phase change box 3049. The heated liquid is converted into gas, and the gas is transferred to the side of the piston rod 3048 through the piston tube 3047. The higher the temperature, the higher the air pressure. The air pressure pushes the piston rod 3048 to move along the inside of the piston tube 3047, and the piston rod 3048 drives the limiting shell 3045 to move, and the limiting shell 304 5 moves along the first slide bar 3042, and the limiting housing 3045 moves to compress the spring of the spring slide bar 3044, thereby increasing the relative area between the side of the limiting housing 3045 and the sealing plate 3046, thereby increasing the gas flow rate, thereby accelerating the heat dissipation speed of the specific area on the side of the welding device 4, thereby helping to cool the side of the welding device 4. When the temperature of the specific area drops, the gas inside the arc-shaped phase change box 3049 turns back into liquid, and the spring of the spring slide bar 3044 releases the elastic force, driving the limiting housing 3045 to return to the closed state, thereby reducing the nitrogen flow in the specific area. At this time, the nitrogen flows to other areas with higher heat generation, so that different heat dissipation speeds are achieved in different areas while the overall flow rate remains unchanged. After cooling, the nitrogen gas is guided to provide gas protection for the workpiece surface.

The top of the downward pressure shell 3071 is fixedly connected to the movable end of the first spring rod 306, and the top of the air inlet pipe 3074 is connected to the bottom of the air supply pipe 308.

[0034] The nitrogen storage tank is placed into the interior of the air guide housing 3051 through the side of the spring limiting rod 3057. The spring limiting rod 3057 limits the nitrogen storage tank. The nitrogen flows through the inner wall of the hollow fan 3053, and the first motor 3052 is started. The driving shaft of the first motor 3052 drives the hollow fan 3053 to rotate, so that the nitrogen is accelerated to generate gas. During the process of heating and gasification, the gas passes through the vent hole 3055 to reach the inner wall of the ventilation pipe 303 and passes through the interior of the heat dissipation housing 301 to cool the surface of the welding device 4. The nitrogen gradually heats up after passing through the surface of the welding device 4, and reaches the interior of the lower pressure shell 3071 through the gas pipe 308. When welding is performed, the moving device 2 drives the heat dissipation housing 30 1 descends, the heat dissipation housing 301 drives the first spring rod 306 downward, and the first spring rod 306 drives the downward pressure housing 3071 to adhere to the surface of the workpiece, thereby fixing the workpiece. Nitrogen enters the air supply pipe 308 into the air inlet pipe 3074 and then into the interior of the downward pressure housing 3071, and is released from the air outlet 3073. The positioning groove 3072 fixes the surface of the workpiece. The angle of the positioning groove 3072 has a certain limiting effect on workpieces of different shapes under the downward pressure of the first spring rod 306. The gas is released through the air outlet 3073 and flows along the surface of the workpiece, directly and directional gas protection is provided to the welding position during welding, and the welding position is directly cooled after welding is completed. Gas protection and cooling of the welding position are achieved, and position limiting is provided. At the same time, the gas reduces the temperature difference through cooling of the welding device 4, thereby preventing the workpiece surface from cooling too quickly and causing embrittlement, and reducing the probability of embrittlement compared to water cooling.

[0035] See also Figure 1-Figure 7The present invention provides a technical solution: the fixing device 5 includes a fixing frame 501, the bottom of the fixing frame 501 is slidably connected to a linear slide 502 through a slide bar, the top of the fixing frame 501 is slidably connected to a support base 503, the top of the inner wall of the support base 503 is fixedly connected to the movable end of a first hydraulic sleeve 504, the fixed end of the first hydraulic sleeve 504 is fixedly connected to the top of the inner wall of the fixing frame 501, the side of the support base 503 is fixedly connected to an arc-shaped sliding ring 505, the inner wall of the arc-shaped sliding ring 505 is slidably connected to a connecting rod 506 through a rotating shaft, the side of the connecting rod 506 is fixedly connected to a clamping bracket 507, the top of the clamping bracket 507 is fixedly connected to a clamping assembly 508, the bottom of the first hydraulic sleeve 504 is slidably connected to an adjustment assembly 509, and the side of the linear slide 502 is fixedly connected to the inner wall of the moving device 2.

[0036] The clamping assembly 508 includes a clamping base plate 5081, the top of the clamping base plate 5081 is fixedly connected to a hydraulic storage box 5082, the side of the hydraulic storage box 5082 is connected to a connecting pipe 5083, the end of the connecting pipe 5083 away from the hydraulic storage box 5082 is connected to the fixed end of the second hydraulic rod 5084, the movable end of the second hydraulic rod 5084 passes through the top of the clamping base plate 5081 and is slidably connected to the clamping base plate 5081, the side of the movable end of the second hydraulic rod 5084 is rotatably connected to the limiting frame 5085 through a rotating shaft, the bottom of the limiting frame 5085 is fixedly connected to an L-shaped bracket 5086, the bottom of the hydraulic storage box 5082 is connected to a liquid inlet pipe 5087, the end of the liquid inlet pipe 5087 away from the hydraulic storage box 5082 is connected to the fixed end side of the first hydraulic sleeve 504, and the side of the clamping base plate 5081 is fixedly connected to the top of the clamping bracket 507.

[0037] When the workpiece is placed on the top of the support base 503, the weight of the workpiece drives the support base 503 to descend, and the descent of the support base 503 drives the arc-shaped sliding ring 505 to move downward, and the downward movement of the arc-shaped sliding ring 505 drives the connecting rod 506 to rotate downward, and the downward rotation of the connecting rod 506 drives the clamping bracket 507 to rotate downward, driving the clamping base plate 5081 to rotate downward, and the downward rotation of the clamping base plate 5081 drives the second hydraulic rod 5084 to move downward to clamp and position the workpiece. When the support base 503 descends, the support base 503 drives the movable end of the first hydraulic sleeve 504 to descend, thereby compressing the inside of the fixed end of the first hydraulic sleeve 504. The hydraulic oil inside the first hydraulic sleeve 504 is compressed, enters the interior of the hydraulic storage box 5082 along the liquid inlet pipe 5087, and enters the second hydraulic rod 5084 through the connecting pipe 5083, thereby driving The movable end of the second hydraulic rod 5084 moves, driving the limit frame 5085 downward, thereby driving the L-shaped bracket 5086 to contact the surface of the workpiece, thereby limiting the workpiece surface. Due to the weight of the workpiece and the different volumes of the first hydraulic sleeve 504 and the second hydraulic rod 5084, the workpiece is stably clamped on the surface of the support base 503. The L-shaped bracket 5086 is adjusted at a certain angle at the movable end of the second hydraulic rod 5084, allowing it to adapt to workpiece surfaces of different shapes, thereby clamping workpieces of different shapes. When the workpiece is removed from the support base after welding, the support base 503 is no longer subject to the weight of the workpiece, thereby releasing the hydraulic oil from the interior of the first hydraulic sleeve 504 and the second hydraulic rod 5084, thereby releasing the workpiece. This achieves the function of self-locking the workpiece during welding, which is beneficial for maintaining a stable state during welding and facilitating welding.

[0038] See also Figures 1-8 The present invention provides a technical solution: the adjustment component 509 includes an adjustment frame 5091, the bottom of the adjustment frame 5091 is penetrated and rotatably connected with an adjustment bolt 5092, the part of the adjustment bolt 5092 located above the adjustment frame 5091 is threadedly connected with an adjustment screw sleeve, the top of the adjustment screw sleeve 5093 is fixedly connected with a hydraulic piston 5094, the hydraulic piston 5094 extends into the fixed end of the first hydraulic sleeve 504 and is slidably connected to the inner wall of the fixed end of the first hydraulic sleeve 504, and the top of the adjustment frame 5091 is fixedly connected to the bottom of the fixed frame 501.

[0039] When the diameter of the workpiece is different and the L-shaped bracket 5086 loses its self-locking function on the workpiece, the adjusting bolt 5092 is manually rotated, and the adjusting bolt 5092 rotates at the bottom of the adjusting frame 5091, thereby driving the adjusting screw sleeve 5093 to rotate through the thread, and the adjusting screw sleeve 5093 rises or falls on the side of the adjusting bolt 5092, thereby changing the amount of descent of the movable end of the first hydraulic sleeve 504, so that the second hydraulic rod 5084 produces different deformation amounts, thereby clamping workpieces of different diameter sizes, thereby performing self-locking clamping on workpieces of different diameter sizes, thereby improving the versatility of the equipment.
