Description

Technical Field

[0001] This utility model relates to the field of steel component welding technology, and specifically to a steel component welding base with a cooling channel. Background Technology

[0002] A steel component welding base is a specialized tooling device used to support, position, and fix steel components. Its main function is to ensure that the components maintain correct geometric shape and dimensional accuracy during the welding process, while improving welding efficiency and quality. Common welding bases typically include a holding mechanism for positioning the steel components. After the steel components to be welded are aligned, the holding mechanism holds and positions them to facilitate welding operations. However, during the welding process, the high temperature of the electric arc causes the steel components to heat up, which is then conducted to the base. Prolonged operation can lead to localized thermal expansion of the base, and the high temperature can also easily burn welding operators.

[0003] Currently, steel component welding bases mostly use external spray cooling or natural heat dissipation cooling methods. Although these two methods can cool the base, spray cooling can easily cause the working environment to deteriorate, and the contact of water with the high-temperature base may cause a quenching effect, leading to local material embrittlement and reducing the service life of the base. Therefore, natural cooling is usually used to cool the base. However, natural cooling results in low heat dissipation efficiency of the base, thereby reducing the welding efficiency of steel components. Utility Model Content

[0029] Example

[0030] To address the technical problems in the background section, the following welded base for steel components with cooling channels is provided:

[0031] Combination Figures 1-7 As shown, the steel component welding base with cooling channel provided by this utility model includes a base 1, a lower base 11 fixedly installed on the top of the base 1, an upper base 12 fixedly installed on the top of the lower base 11 and sleeved on the outside, and channel grooves 2 with arc-shaped cross sections are opened on the opposite sides of the lower base 11 and the upper base 12. The two channel grooves 2 are symmetrically arranged, and copper pipes 3 are installed in the two channel grooves 2. The outer side wall of the copper pipes 3 is in contact with both the lower base 11 and the upper base 12. The two ends of the copper pipes 3 extend to the outer sides of the two ends of the lower base 11 respectively.

[0032] An air extraction assembly 4 is fixedly installed on the base 1 and on one side of the lower base 11 along its length. The air inlet end of the air extraction assembly 4 is connected to one end of the copper pipe 3. A filter assembly 5 is installed on the base 1 and on the other side of the lower base 11 along its length, and is connected to the other end of the copper pipe 3. The filter assembly 5 is used to filter dust in the air entering the copper pipe 3. A pressing mechanism 6 extending to the upper base 12 is installed on the base 1, which is used to press and position the steel components welded on the upper base 12.

[0033] In use, when welding steel components, an external gantry crane is used to hoist the steel components to be welded onto the upper base 12 for joint alignment. Then, the holding mechanism 6 holds and positions the steel components welded on the upper base 12. During welding, the steel components themselves heat up, transferring heat to the upper base 12, causing the upper base 12 to heat up. During this process, the air extraction component 4 draws air out of the copper pipe 3, while external air enters the copper pipe 3 through the other end, allowing air circulation within the copper pipe 3. Because the copper pipe 3 is in close contact with the upper base 12, heat from the upper base 12 is transferred to the copper pipe 3. The airflow within the copper pipe 3 helps to hold the steel components in place. The heat from the copper pipe 3 is carried away, achieving a heat dissipation effect on the copper pipe 3 and the upper base 12. This allows for simultaneous welding of the steel components and cooling of the upper base 12. The design of the air extraction component 4 and the copper pipe 3 replaces the natural heat dissipation cooling method of the base, accelerating the cooling of the base and improving heat dissipation efficiency, thereby improving the welding efficiency of the steel components. The design of the filter component 5 achieves a dust filtration effect in the air entering the copper pipe 3, effectively preventing dust from entering the copper pipe 3 and adhering to the inner wall of the copper pipe 3, thus affecting the airflow inside the copper pipe 3. At the same time, it facilitates contact between the air and the copper pipe 3, which is beneficial for heat dissipation.

[0034] Combination Figures 1-7 As shown, the air extraction assembly 4 includes a mounting shell 42 fixedly installed on the top of the base 1 by a fixing plate 41. There is a gap between the bottom of the mounting shell 42 and the base 1, and the bottom of the mounting shell 42 is open. The end of the copper tube 3 is connected to the top of the mounting shell 42. An exhaust fan 43 is fixedly installed inside the mounting shell 42. Specifically, the air outlet of the exhaust fan 43 is located on one side of the open end of the mounting shell 42. When in use, the exhaust fan 43 is turned on, and the exhaust fan 43 works to draw the air out of the mounting shell 42, so that the air in the copper tube 3 can enter the mounting shell 42. The air from the outside enters the copper tube 3 through the filter assembly 5, thereby accelerating the air circulation inside the copper tube 3.

[0035] Combination Figures 1-7As shown, the filter assembly 5 includes a filter housing 51 fixedly installed on the top of the base 1. One side of the filter housing 51 is open, and the other end of the copper tube 3 is connected to the filter housing 51. The top of the filter housing 51 has a slot 52 that communicates with its interior. A filter plate 53 for sealing the interior of the filter housing 51 is inserted on the filter housing 51 and located in the slot 52. The filter plate 53 is a high-efficiency filter. When in use, when external air passes through the filter assembly 5 and enters the copper tube 3, the air enters the filter housing 51 through the open end of the filter housing 51 and then flows into the interior of the copper tube 3. During this process, the filter plate 53 filters the dust in the air, effectively preventing dust from entering the copper tube 3 and achieving the effect of filtering dust in the air. The design of inserting the filter plate 53 into the slot 52 facilitates the installation and removal of the filter plate 53, thereby facilitating the cleaning or replacement of the filter plate 53.

[0036] Combination Figures 1-7 As shown, the pressing mechanism 6 includes a fixed seat 61 installed on the top of the base 1 and located on one side of the width direction of the lower base 11. A base plate 62 is installed on the top of the fixed seat 61. Vertical telescopic rods 63 are symmetrically fixed on the top of the base plate 62. Connecting seats 64 are fixedly installed on the top of the two telescopic rods 63. An electric cylinder 65 is fixedly installed on the top of the base plate 62 and is connected to the connecting seat 64. A moving block 66 is slidably installed on the connecting seat 64 in the horizontal direction. A driving component 67 for driving the moving block 66 to slide is installed on the connecting seat 64. A vertical telescopic rod 68 is fixedly installed on the bottom of the moving block 66. A connecting block 69 is fixedly installed on the bottom of the telescopic rod 68. A connecting block 69 is fixedly installed on the bottom of the moving block 66. The device is equipped with an electric cylinder 661 that is fixedly connected to the connecting block 69. The bottom of the connecting block 69 is fitted with a pressure plate 691 that can contact the top of the upper base 12. In use, when the steel component to be welded is placed on the top of the upper base 12 and the welding operation is performed, the moving block 66 is made to slide horizontally on the connecting seat 64 by the drive component 67, which drives the pressure plate 691 to move above the steel component. At this time, the electric cylinder 65 is controlled to move the connecting seat 64 downward along the two telescopic rods 63, and the electric cylinder 661 is controlled to move the connecting block 69 downward along the telescopic rod 68, which drives the pressure plate 691 to move downward, so that the pressure plate 691 abuts against the top of the steel component to be welded, thereby achieving the effect of pressing and positioning the steel component to be welded.

[0037] Combination Figures 1-7As shown, the driving component 67 includes a threaded post 671 that is horizontally rotatably mounted on the connecting seat 64. The threaded post 671 is threadedly connected to the movable block 66. A motor 672 for driving the threaded post 671 to rotate is fixedly mounted on the connecting seat 64. In use, the motor 672 is turned on, and the output shaft of the motor 672 rotates, which drives the threaded post 671 to rotate on the connecting seat 64, thereby driving the movable block 66 to slide horizontally on the connecting seat 64, which is convenient for control.

[0038] Combination Figures 1-7 As shown, the fixed base 61 includes a fixed frame 611 fixedly installed on the top of the base 1. A vertically oriented rotating shaft 612 is rotatably mounted on the top of the fixed frame 611. The base plate 62 is fixedly connected to the top of the rotating shaft 612 and fits against the fixed frame 611. A second motor 613 is fixedly installed on the base 1. The output shaft of the second motor 613 is connected to the rotating shaft 612 through a bevel gear assembly 614. The bevel gear assembly 614 includes two meshing bevel gears. One bevel gear is coaxially fixedly connected to the rotating shaft 612, and the other bevel gear is... The output shaft of the second motor 613 is coaxially fixed. Through the special design of the fixed base 61, which includes a fixed frame 611, a rotating shaft 612, the second motor 613, and a bevel gear assembly 614, when in use, the second motor 613 is controlled to work. The output shaft of the second motor 613 rotates, which drives the rotating shaft 612 to rotate through the bevel gear assembly 614. This drives the base plate 62 to rotate, causing the connecting seat 64 to rotate around the rotating shaft 612 to the outside of the upper base 12. This achieves a clearance effect above the upper base 12, which facilitates the loading and unloading of steel components by an external gantry crane.

[0039] Combination Figures 1-7 As shown, the pressure plate 691 is hinged to the bottom of the connecting block 69. Specifically, the top middle position of the pressure plate 691 is hinged to the connecting block 69. Utilizing the unique design of the pressure plate 691 hinged to the bottom of the connecting block 69, when the top of the steel component to be welded after the top of the upper base 12 is aligned is not in a horizontal state, the pressure plate 691 moves downward and abuts against the top of the steel component to be welded. The pressure plate 691 rotates on the connecting block 69, increasing the contact area between the pressure plate 691 and the top of the steel component to be welded, thereby improving the pressure and positioning effect of the steel component to be welded.

[0040] Combination Figures 1-7 As shown, the cross-section of the channel groove 2 is serpentine. One end of the copper tube 3 is located on one side of the lower base 11 along its length, and the other end is located on the other side of the lower base 11 along its length. The serpentine cross-section of the channel groove 2 increases the contact surface between the upper base 12 and the copper tube 3, which helps to conduct the temperature on the upper base 12 to the copper tube 3, thus increasing the heat conduction effect from the upper base 12 to the copper tube 3. The air flowing inside the copper tube 3 carries away the temperature on the copper tube 3, thereby improving the heat dissipation effect on the upper base 12.

[0041] Working principle and usage process of this utility model:

[0042] When welding steel components, control motor 613 operates, causing connecting seat 64 to rotate around shaft 612 to the outside of upper base 12, making room above upper base 12. An external gantry crane can then lift the steel component onto upper base 12. After stacking and aligning the two steel components to be welded, control motor 613 causes connecting seat 64 to rotate around shaft 612 and reset. Control motor 672 is then activated, causing threaded column 671 to rotate on connecting seat 64. Moving block 66 slides horizontally on connecting seat 64, moving pressure plate 691 above the steel component. Through the cooperation of electric cylinder 65 and electric cylinder 661, pressure plate 691 moves downward, contacting the top of the steel component to be welded, thus pressing and positioning the component. During welding, the steel component's temperature rises, transferring heat to upper base 12, causing upper base 12 to heat up. The heat from upper base 12 is then transferred to copper pipe 3. During the process, the exhaust fan 43 is turned on, drawing air out of the mounting shell 42 and allowing air from the copper tube 3 to enter the mounting shell 42. External air flows through the filter plate 53 and filter shell 51 into the copper tube 3, allowing air circulation within the copper tube 3. This air circulation carries away heat from the copper tube 3, dissipating heat and achieving a cooling effect on the upper base 12. This allows for simultaneous welding of the steel components and cooling of the upper base 12, replacing the natural cooling method and accelerating cooling of the base, thus improving heat dissipation efficiency and welding efficiency. Furthermore, when external air passes through the filter plate 53 into the filter shell 51, the filter plate 53 filters dust from the air, effectively preventing dust from entering the copper tube 3 and adhering to its inner wall, thus affecting airflow. This also facilitates contact between the air and the copper tube 3, promoting heat dissipation.
