Description

Technical Field

[0001] The present application relates to the technical field of high-frequency heating welding, and in particular to a high-frequency induction welding device for welded pipes. Background Art

[0002] Welded steel pipe refers to a steel pipe with a seam on the surface that is made by bending steel strips or steel plates into round, square and other shapes and then welding them. The blank used for welded steel pipes is steel plates or strip steel.

[0003] The existing patent (publication number: CN216858577U) discloses a high-frequency induction welding device suitable for steel pipe processing, including a main body and a clamping block, a control panel is installed on the front of the main body, wherein the front of the main body is connected with a connecting port, the end of the connecting port is fixedly connected with a clamping plate, the side of the connecting port is connected with a threaded sleeve, the end face of the threaded sleeve is fixedly connected with an extrusion ring, the inside of the connecting port is connected with a heating tube, and the front of the main body is fixedly connected with a fixing seat. The high-frequency induction welding device suitable for steel pipe processing places the steel pipe between the heating tube and the clamping block, and the motor can drive the bidirectional threaded rod to rotate when it is working. When the bidirectional threaded rod rotates, it can drive the sliding block to slide the thread. When the sliding block slides, it can slide toward each other through the sliding groove. When the sliding block slides, it can drive the connecting rod and the clamping block to move. When the clamping block moves, it can clamp and fix the steel pipe, which is convenient for clamping and fixing the steel pipe when welding.

[0004] However, during the welding process of the above device, the initial temperature of the steel strip changes after extrusion during the high-frequency heating process, which causes the shape of the steel pipe after welding to change easily during the uncooling process, causing the size of the steel pipe to change, and the required accuracy cannot be achieved, resulting in material waste. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a high-frequency induction welding device for welded pipes, which has the advantages of anti-deformation, etc., and solves the problem that during the welding process, the initial temperature of the steel strip changes after extrusion during the high-frequency heating process, which causes the shape of the steel pipe after welding to change easily during the uncooling process, causing the size of the steel pipe to change, and the required accuracy cannot be achieved, resulting in material waste.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a high-frequency induction welding device for welded pipes, comprising a work frame, wherein two rotating shafts are rotatably connected inside the work frame, and the lower ends of the two rotating shafts are fixedly connected to column gears, the upper end of the work frame is fixedly connected to a high-frequency heating machine mounting frame, the upper end of the work frame close to the high-frequency heating machine mounting frame is fixedly connected to a gantry mounting frame, the gantry mounting frame is fixedly connected to a fixed frame inside, the lower end of the fixed frame is fixedly connected to a fixed column, and the end of the work frame away from the high-frequency heating machine mounting frame is fixedly connected to two fixed plates.

[0007] The upper ends of the two fixed plates are fixedly connected to an outer anti-deformation wheel mounting frame, and a plurality of outer anti-deformation wheels are rotatably connected inside the outer anti-deformation wheel mounting frame. A fixed column fixedly connected to the lower end of the fixed frame extends into the inner part of the outer anti-deformation wheel mounting frame, and a plurality of inner anti-deformation wheel mounting frames are respectively fixedly connected to positions corresponding to the plurality of outer anti-deformation wheels. The plurality of inner anti-deformation wheel mounting frames are all rotatably connected inside thereof.

[0008] Through the above scheme, a plurality of inner anti-deformation wheel mounting frames are fixedly connected to the outside of the fixed column, the inner anti-deformation wheels are rotatably connected to the inner anti-deformation wheel mounting frames, and at the same time, two fixed plates are fixedly connected to the upper end of the workbench, and then an outer anti-deformation wheel mounting frame is fixedly arranged on the upper end of the fixed plate, and a plurality of outer anti-deformation wheels are rotatably connected to the positions corresponding to the inner anti-deformation wheels inside the outer anti-deformation wheel mounting frame. During use, when the welded steel pipe reaches the air strike between the inner anti-deformation wheel and the outer anti-deformation wheel, the nozzle is started to cool down the welded steel pipe. At the same time, the inner anti-deformation wheel and the outer anti-deformation wheel cooperate with each other to constrain the shape of the steel pipe, thereby preventing the steel pipe from changing in shape during the cooling process, causing the steel pipe size to change, failing to achieve the required accuracy, and causing material waste.

[0009] Furthermore, a high-frequency heater is fixedly connected to the upper end of the high-frequency heater mounting frame, and a heating coil is fixedly connected to the surface of the high-frequency heater.

[0010] Through the above scheme, the heating coil and the high-frequency heating machine can be used together to heat the steel pipe so that the steel pipe can be further processed later.

[0011] Furthermore, a water pipe fixing frame is fixedly connected to one end of the working frame close to a fixing plate fixedly connected to the upper end of the working frame.

[0012] Through the above solution, the water pipe fixing frame is used to fix the water pipe used to cool the steel pipe.

[0013] Furthermore, a water pipe is fixedly connected to the upper end of the water pipe fixing frame fixedly connected between the working frames, and a plurality of nozzles are fixedly connected to the surface of the water pipe.

[0014] Through the above scheme, the water pipe is connected to the cooling water source, and then the processed steel pipe can be cooled through the nozzle.

[0015] Furthermore, the upper ends of the two rotating shafts are fixedly connected with extrusion wheels.

[0016] Through the above scheme, the gap between the two extrusion wheels is smaller than the diameter of the unprocessed steel pipe, and the steel pipe can be extruded during processing, so that the gap between the steel pipes being processed disappears.

[0017] Furthermore, the two column gears are meshed with each other.

[0018] According to the above solution, when one of the two column gears rotates, the other column gear will rotate in the opposite direction because the two column gears are meshed with each other.

[0019] Furthermore, a motor mounting frame is fixedly connected to the lower end of the working frame, and a motor is fixedly connected inside the motor mounting frame.

[0020] Through the above solution, the motor fixedly arranged inside the motor mounting frame is used to provide power to the bevel gear.

[0021] Furthermore, a bevel gear is fixedly connected to the output end of the motor, and the bevel gear is meshed with the driven gear.

[0022] According to the above scheme, when the motor is started, it will drive the bevel gear to rotate, and the bevel gear is meshed with the driven gear, so the bevel gear will drive the driven gear to rotate and thus drive one of the two column gears to rotate synchronously.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The high-frequency induction welding device for welding pipes has a plurality of inner anti-deformation wheel mounting frames fixedly connected to the outside of a fixed column, an inner anti-deformation wheel is rotatably connected to the inside of the inner anti-deformation wheel mounting frames, and two fixed plates are fixedly connected to the upper end of a workbench. An outer anti-deformation wheel mounting frame is fixedly arranged on the upper end of the fixed plate, and a plurality of outer anti-deformation wheels are rotatably connected to the positions corresponding to the inner anti-deformation wheels inside the outer anti-deformation wheel mounting frame. During use, when the welded steel pipe reaches the airspace between the inner anti-deformation wheel and the outer anti-deformation wheel, a nozzle is started to cool the welded steel pipe. At the same time, the inner anti-deformation wheel and the outer anti-deformation wheel cooperate with each other to constrain the shape of the steel pipe, thereby preventing the steel pipe from changing in shape during the cooling process, causing the steel pipe size to change, failing to achieve the required accuracy, and causing material waste.
