Description

Technical Field

[0001] This utility model relates to the field of plasma beveling machine technology, specifically a plasma beveling machine for thin-walled pipe fittings. Background Technology

[0002] A plasma beveling machine is a specialized piece of equipment that uses the thermal energy of a plasma arc to bevele metal sheets, pipes, and other materials. It rapidly melts and blows away the metal using a high-temperature plasma arc, creating the desired bevel shape on the workpiece edge, preparing it for subsequent welding processes.

[0003] In existing plasma beveling technology, the processing equipment is not convenient for circling the round pipe, resulting in low overall processing efficiency. Therefore, an improved plasma beveling machine for thin-walled pipes is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a plasma beveling machine for thin-walled pipe fittings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plasma beveling machine for thin-walled pipe fittings, comprising a base plate, a processing mechanism for beveling is provided on one side of the upper end of the base plate, the processing mechanism comprising a support plate, a worm gear reducer, a rotating component, an extension component, a fixed ring, a rotating component, and a spray gun head. The support plate is fixedly provided on one side of the upper end of the base plate, the worm gear reducer is fixedly provided on the upper end of the support plate, the rotating component is provided in the middle of the surface of the worm gear reducer, the extension component is fixedly provided on the outer side of the rotating component, the fixed ring is fixedly provided on one side of the surface of the extension component, the rotating component is movably arranged inside the fixed ring through a bearing, and the spray gun head is movably inserted into one side of the surface of the rotating component.

[0006] Preferably, an electric motor is fixedly installed on one side of the worm gear reducer. The power output shaft of the electric motor is connected to the rotating component through the worm gear reducer. The electric motor drives the worm gear reducer to rotate, thereby driving the rotating component and all components on the surface of the rotating component to rotate together.

[0007] Preferably, the outer surface of the fixing ring is provided with a first locking screw by means of a thread, which can be used to press the rotating part to fix the angle of the rotating part.

[0008] Preferably, the surface of the rotating part is provided with a second locking screw by means of a thread, and tightening the second locking screw can fix the position of the spray gun head.

[0009] Preferably, the surface of the fixing ring is provided with scale lines, which can be used to easily determine the tilt angle of the spray gun head driven by the position of the rotating component.

[0010] Preferably, a clamping vise is fixedly installed on one side of the support plate at the upper end of the base plate, which can be used to fix the pipe to be processed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. As the spray gun head completes 360° circumferential processing along the outer circumference of the pipe fitting, the end face of the pipe fitting will naturally form a bevel (groove) that meets the requirements of the welding process. Thus, this device can be used for processing pipe fittings.

[0012] 2. This utility model's spray gun head features a wide range of tilt angle adjustment capabilities, and its distance adjustment from the fitting is convenient. Specifically, the tilt angle can be adjusted by rotating the rotating component; the tilt angle of the spray gun head can be accurately determined using the scale markings, and then secured with the first locking screw. Distance adjustment is even more flexible; simply pull the spray gun head out, and after adjusting to the target distance, tighten the second locking screw to secure the spray gun head. This design allows the device to easily adjust the angle of the processed bevel according to actual needs, thus significantly improving its applicability. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution: a plasma beveling machine for thin-walled pipe fittings, including a base plate 1. A processing mechanism for beveling is provided on one side of the upper end of the base plate 1. The processing mechanism includes a support plate 2, a worm gear reducer 3, a rotating component 4, an extension component 5, a fixing ring 6, a rotating component 7, and a spray gun head 8. The support plate 2 is fixedly provided on one side of the upper end of the base plate 1. The worm gear reducer 3 is fixedly provided on the upper end of the support plate 2. The rotating component 4 is provided in the middle of the surface of the worm gear reducer 3. The extension component 5 is fixedly provided on the outer side of the rotating component 4. The fixing ring 6 is fixedly provided on one side of the surface of the extension component 5. The rotating component 7 is movably provided inside the fixing ring 6 through a bearing. The spray gun head 8 is movably inserted into one side of the surface of the rotating component 7.

[0017] A motor 9 is fixedly installed on one side of the surface of the worm gear reducer 3. The power output shaft end of the motor 9 is connected to the rotating part 7 through the worm gear reducer 3. The motor 9 drives the worm gear reducer 3 to rotate, thereby driving the rotating part 4 and all the components on the surface of the rotating part 4 to rotate together. The outer surface of the fixed ring 6 is provided with a first locking screw 10 by a threaded engagement. The first locking screw 10 can be used to press the rotating part 7 to fix the angle of the rotating part 7. The rotating part 7 has a second locking screw 11 screwed into it by a thread. Tightening the second locking screw 11 can fix the position of the spray gun head 8. The fixed ring 6 has a scale line 12 on its surface. The scale line 12 can be used to easily determine the tilt angle of the spray gun head 8 driven by the position of the rotating part 7. A clamping vise 13 is fixedly installed on one side of the support plate 2 at the upper end of the base plate 1. The clamping vise 13 can be used to fix the pipe to be processed. Working Principle: This device adjusts the angle between the spray gun head 8 and the pipe fitting to create a specific processing angle. The spray gun head 8 then sprays a high-temperature plasma arc at a downward angle, rapidly heating and melting the surface of the pipe fitting. Simultaneously, a high-speed airflow is blown out, precisely stripping away the molten layer from the pipe fitting surface. As the spray gun head 8 completes a 360° circumferential process around the outer circumference of the pipe fitting, a bevel (groove) naturally forms on the end face of the pipe fitting, meeting the welding process requirements. This bevel design significantly improves the process adaptability of subsequent butt welding. By increasing the weld contact area and optimizing the penetration depth distribution, it effectively enhances the mechanical properties and durability of the weld joint, ultimately achieving a systematic improvement in the welding quality of the pipe fitting joint. Meanwhile, the spray gun head 8 of this device has a wide range of tilt angle adjustment function, and its distance adjustment from the fitting is convenient. Specifically, the tilt angle can be adjusted by rotating the rotating part 7. Combined with the scale markings, the tilt of the spray gun head 8 can be accurately determined, and then it can be tightened with the first locking screw 10. The distance adjustment is even more flexible. Simply pull the spray gun head 8 out, and after adjusting it to the target distance, only the second locking screw 11 needs to be tightened to fix the spray gun head 8. This design allows the device to easily adjust the bevel angle of the processing bevel according to actual needs, thereby significantly improving its applicability.
