Description

Technical Field

[0001] The present invention relates to the technical field of welding machines, and particularly to a punching high-frequency welded pipe unit. Background Art

[0002] In the field of pipe processing, a punching high-frequency welded pipe unit is a key device for producing welded pipes with specific hole structures. With the continuous development of industrial technology, the quality and performance requirements for welded pipes are increasing day by day. Especially in some industries with strict requirements for pipe sealing, structural strength, and processing accuracy, such as the petrochemical, machinery manufacturing, and construction industries, the demand for high-quality welded pipe products continues to grow.

[0003] During the welding and punching process of traditional punching high-frequency welded pipe units, air bubbles will be generated at the welded holes. The existence of these air bubbles will seriously affect the quality of the surface of the welded holes, resulting in a reduction in the structural strength at the welded holes and a deterioration in sealing performance, making it impossible to meet some application scenarios with high quality requirements for welded pipes. Moreover, during the welding process of traditional equipment, the sealing treatment between the welded pipe and the welding component is not perfect enough, and air is likely to remain at the welded hole position, further exacerbating the risk of air bubble generation and making it difficult to ensure the stability of the quality of the welded holes.

A sliding rod is fixedly installed on the surface of the top plate close to the air permeable holes. A piston with a sealing function is slidably installed on the surface of the sliding rod. A spring is installed between the piston and the top plate.

[0006] As a preferred technical solution of the present invention, the air suction component includes an air pump installed at one end of one side of the bottom plate. An air plate is fixedly installed on the surface of the fixing plate. The output end of the air pump is communicated with the air plate. A connecting pipe is installed in a communicating manner between the air plate and the inner cavity of the annular plate.

[0007] As a preferred technical solution of the present invention, a sleeve plate is fixedly installed at the top end of the annular plate. A sealing collar with deformation rubber ability is installed at the top end of the sleeve plate, and the welding head of the welding component is inserted into the interior of the sealing collar.

[0008] As a preferred technical solution of the present invention, a filtering component is arranged inside the annular plate. The filtering component includes a filter box installed inside the annular plate. Activated crushed carbon is arranged inside the filter box. An air suction pipe for filtering gas is connected and installed between the inner cavities of the filter box and the sealing collar.

[0009] As a preferred technical solution of the present invention, a magnetic attraction pressing plate for adsorbing the pipe body is installed at the position where the annular plate is welded to the surface of the pipe body, and the magnetic attraction pressing plate is attached to the surface of the pipe body.

[0010] As a preferred technical solution of the present invention, longitudinal roller components are arranged at the top end of the base. A limiting mechanism with transverse roller components is arranged at the top end of the bottom plate. A limiting frame is installed at the top end of the bottom plate. The transverse roller components are installed on the surface of the limiting frame, and the pipe body is slidably installed between the longitudinal roller components and the transverse roller components.

[0011] As a preferred technical solution of the present invention, the longitudinal roller components include two roller bodies rotatably installed at the top end of the base, and the pipe body is inserted between the two roller bodies. Grooves are formed on the surface of the roller body close to the pipe body, and a cooling cavity filled with cooling water is formed inside the roller body.

[0012] As a preferred technical solution of the present invention, heating wires for preheating the pipe body are installed on the inner wall of the transverse roller components close to the pipe body. A spiral impeller is rotatably installed inside the transverse roller components, and a motor for driving the spiral impeller is installed inside the bottom plate.

A rotating shaft is rotatably installed between the two symmetrically arranged movable frames, and the roller body is installed on the surface of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. During the welding hole process of the present invention, the air pump exhausts the welding area through the annular plate. The vent holes provided near the welding hole position of the annular plate can effectively discharge the gas generated during welding, reducing the bubbles in the welding hole. At the same time, the piston in the sealing assembly can move within the vent hole under the action of the spring, sealing the welding hole position while exhausting gas, reducing air circulation, and minimizing the air residue at the welding hole position to the greatest extent, thereby ensuring the stable quality of the welding hole surface and meeting the application scenarios with high requirements for welding hole quality.

[0015] 2. By setting the transverse roller component and the longitudinal roller component, the present invention realizes the stability of the transverse and longitudinal movement of the pipe body. The stable pipe body transportation reduces the shaking and deviation during the punching process, improves the punching accuracy, reduces the unqualified rate of products caused by the instability of the pipe body, and avoids scratches and other damages on the surface of the pipe.

[0016] 3. The transverse roller component of the present invention is installed with heating wires near the inner wall of the pipe body, which can heat the surface of the transverse roller component, thereby realizing the preheating of the pipe body surface. The preheating treatment can avoid the thermal effect during subsequent punching and improve the punching quality. The cooling cavity filled with cooling water is arranged inside the roller body of the longitudinal roller component. When the punched pipe passes through the longitudinal roller component, the cooling water can cool the pipe body, avoiding the deformation of the pipe body caused by the continuous residual high temperature and ensuring the subsequent use performance and overall quality of the pipe body.

[0017] 4. The present invention is provided with a sealing sleeve ring with the ability of deformable rubber at the top of the annular plate. When the welding head of the welding component is inserted therein, it can effectively seal between the welded pipe and the annular plate. This deformable sealing sleeve ring can be adaptively adjusted according to the gap between the welded pipe and the annular plate, making the exhaust process more stable, further reducing the air residue at the welding hole position, and providing a strong guarantee for the stability of the welding hole.

[0018] 5. The present invention is installed with a magnetic adsorption pressing plate at the welding position, which can adsorb the pipe body, increasing the stability of the pipe body during the welding and punching process. During welding and punching, the adsorption effect of the magnetic adsorption pressing plate on the pipe body can effectively reduce the deformation problem of the pipe body caused during the welding process, ensure the shape and dimensional accuracy of the pipe body during the processing, and improve the qualified rate and quality stability of the product.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-10 , the present invention provides a punching high-frequency welded pipe unit, including a base 1 and a pipe body 6. One side of the base 1 is provided with a bottom plate 5. The top of the bottom plate 5 is provided with an exhaust mechanism 8 with an annular plate 834. The top of the bottom plate 5 is fixedly installed with a fixing plate 81. A welding component 82 is installed in the middle of the fixing plate 81. The annular plate 834 is installed at a position of the fixing plate 81 close to the welding component 82, and the pipe body 6 is slidably installed inside the annular plate 834. One side of the bottom plate 5 is provided with a suction component 83, and the suction end of the suction component 83 is communicated with the annular plate 834.

[0023] Among them, the pipe body 6 is welded and punched through the welding component 82, and during the welding process, the gas at the welding position can be discharged through the air suction component 83 to ensure welding stability.

[0024] In the technical solution of the embodiment of the present application, a sealing component 837 is arranged inside the annular plate 834. The sealing component 837 includes a top plate 8371 installed on the inner wall of the annular plate 834. A plurality of air permeation holes 8375 for discharging welding air holes are opened at the position of the annular plate 834 close to the welding hole. A sliding rod 8372 is fixedly installed on the surface of the top plate 8371 close to the air permeation holes 8375. A piston 8374 with a sealing function is slidably installed on the surface of the sliding rod 8372. A spring 8373 is installed between the piston 8374 and the top plate 8371.

[0025] Among them, during the welding and punching process, welding air holes will generate gas, and the air permeation holes 8375 are opened at the position of the annular plate 834 close to the welding hole. At this time, by starting the air pump 831, the gas in the welding air holes can be discharged. In the sealing component 837, a spring 8373 is installed between the piston 8374 and the top plate 8371. The piston 8374 can slide on the surface of the sliding rod 8372. When exhaust is required, the gas pressure pushes the piston 8374 to move, and the gas is discharged. After the exhaust is completed, the elastic force of the spring 8373 makes the piston 8374 reset, seals the position of the welding hole, reduces air circulation, effectively discharges the gas in the welding air holes, and ensures the stability of the surface quality of the welding hole.

[0026] In some embodiments, the air suction component 83 includes an air pump 831 installed at one end of one side of the bottom plate 5. An air plate 832 is fixedly installed on the surface of the fixing plate 81. The output end of the air pump 831 is communicated with the air plate 832. A connecting pipe 833 is installed in a communicating manner between the air plate 832 and the inner cavity of the annular plate 834.

[0027] Among them, after the air pump 831 is started, the gas is extracted from its output end and transported to the air plate 832. The air plate 832 and the inner cavity of the annular plate 834 are communicated through the connecting pipe 833, so as to form a negative pressure in the inner cavity of the annular plate 834, enabling the gas generated at the welding position to smoothly enter the inner cavity of the annular plate 834 through the air permeation holes 8375, and then be discharged through the connecting pipe 833 and the air plate 832 to achieve effective exhaust.

[0028] In some embodiments, a sleeve plate 835 is fixedly installed at the top end of the annular plate 834. A sealing sleeve 836 with rubber deformation ability is installed at the top end of the sleeve plate 835, and the welding head of the welding component 82 is inserted into the inside of the sealing sleeve 836.

[0029] Among them, when the welding head of the welding component 82 is inserted inside the sealing ferrule 836, the sealing ferrule 836 can deform according to the gap between the welded pipe and the annular plate 834, closely fit between the two, fill the gap, thereby enhancing the sealing performance, ensuring the stability of the exhaust process, and reducing air residue.

[0030] In some embodiments, a filtering assembly 839 is provided inside the annular plate 834. The filtering assembly 839 includes a filter box 8392 installed inside the annular plate 834. Activated crushed carbon is provided inside the filter box 8392. An air suction pipe 8391 for filtering gas is connected and installed between the inner cavities of the filter box 8392 and the sealing ferrule 836.

[0031] Among them, the air suction pipe 8391 connects the inner cavities of the filter box 8392 and the sealing ferrule 836. When the gas enters the filter box 8392 from the inner cavity of the sealing ferrule 836 through the air suction pipe 8391, the activated crushed carbon has an adsorption effect, can adsorb harmful substances in the gas, filter the gas, and then discharge the filtered gas, achieving the purpose of environmental protection and equipment protection.

[0032] In some embodiments, a magnetic pressing plate 838 for adsorbing the pipe body 6 is installed at the welding position on the surface of the annular plate 834 close to the pipe body 6, and the magnetic pressing plate 838 fits on the surface of the pipe body 6.

[0033] Among them, a magnetic pressing plate 838 is installed at the welding position on the surface of the annular plate 834 close to the pipe body 6. The magnetic pressing plate 838 has magnetism and can adsorb the pipe body 6, so that the pipe body 6 remains stable during the welding and punching process, avoiding the pipe body 6 from shaking or deforming due to the external force during the welding process, thereby improving the dimensional accuracy and quality stability of the product.

[0034] In some embodiments, a longitudinal roller component 4 is provided at the top end of the base 1, a limiting mechanism 7 with a transverse roller component 73 is provided at the top end of the bottom plate 5, a limiting frame 71 is installed at the top end of the bottom plate 5, the transverse roller component 73 is installed on the surface of the limiting frame 71, and the pipe body 6 is slidably installed between the longitudinal roller component 4 and the transverse roller component 73.

[0035] Among them, the pipe body 6 is slidably installed between the longitudinal roller component 4 and the transverse roller component 73. The longitudinal roller component 4 and the transverse roller component 73 respectively limit and support the pipe body 6 longitudinally and transversely, so that the pipe body 6 remains stable during the movement, ensuring the accuracy of the welding and punching position.

[0036] In some embodiments, the longitudinal roller component 4 includes two roller bodies 42 rotatably installed at the top end of the base 1, and the pipe body 6 is inserted between the two roller bodies 42. A groove 41 is provided on the surface of the roller body 42 close to the pipe body 6, and a cooling cavity 44 filled with cooling water is provided inside the roller body 42.

[0037] Among them, the longitudinal roller component 4 includes two roller bodies 42 rotatably mounted on the top end of the base 1. The pipe body 6 is inserted between the two roller bodies 42. A groove 41 is formed on the surface of the roller body 42 close to the pipe body 6, which can limit the pipe body 6 to prevent the pipe body 6 from shifting. A cooling cavity 44 filled with cooling water is formed inside the roller body 42. When the punched pipe body 6 passes through the roller body 42, the cooling water can absorb the heat on the pipe body 6 to cool the pipe body 6 and prevent the pipe body 6 from deforming due to high temperature.

[0038] In some embodiments, a heating wire 74 for preheating the pipe body 6 is installed on the inner wall of the transverse roller component 73 close to the pipe body 6. A spiral impeller 72 is rotatably installed inside the transverse roller component 73, and a motor for driving the spiral impeller 72 is installed inside the bottom plate 5.

[0039] Among them, a heating wire 74 is installed on the inner wall of the transverse roller component 73 close to the pipe body 6. After the heating wire 74 is powered on, it generates heat to heat the surface of the transverse roller component 73, and then preheats the surface of the pipe body 6, reducing the thermal effect generated due to excessive temperature change during subsequent welding holes and improving the punching quality. A spiral impeller 72 is rotatably installed inside the transverse roller component 73, and a motor for driving the spiral impeller 72 is installed inside the bottom plate 5. The motor drives the spiral impeller 72 to rotate, and through the spiral impeller 72, the heat flow inside the transverse roller component 73 can be dissipated more evenly, ensuring the stable preheating effect on the surface of the pipe body 6 and improving the welding hole quality.

[0040] In some embodiments, two support frames 2 are fixedly installed on the top end of the base 1. Two moving frames 3 for adjusting the angle are slidably installed inside the support frames 2. A rotating shaft 43 is rotatably installed between the two symmetrically arranged moving frames 3, and the roller body 42 is installed on the surface of the rotating shaft 43.

[0041] Among them, by moving the position of the moving frame 3 inside the support frame 2, the rotating shaft 43 and the roller body 42 can be driven to move, thereby adjusting the angle of the roller body 42, enabling the device to adapt to the processing of pipe bodies 6 with different diameters and different shapes, and improving the versatility and flexibility of the device.

[0042] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
