Description

Technical Field

[0001] This invention relates to the field of welding technology for irregularly shaped pipe fittings, and particularly to a welding equipment and welding method for irregularly shaped pipe fittings. Background Technology

[0002] Welding, also known as fusion welding or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding achieves the joining purpose through the following three methods: 1. Fusion welding—Heating the workpieces to be joined causes localized melting to form a molten pool. After the molten pool cools and solidifies, the joint is formed. Filler material can be added if necessary. It is suitable for welding various metals and alloys and does not require pressure. 2. Pressure welding—Pressure must be applied to the workpieces during the welding process. It is suitable for various metal materials and some metal materials. 3. Brazing—Using a filler metal with a lower melting point than the base metal, the liquid filler metal wets the base metal, fills the joint gap, and diffuses with the base metal to achieve a connection. It is suitable for welding various materials, as well as different metals or dissimilar materials. Modern welding uses many energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can also be performed in various environments, such as outdoors, underwater, and in space. Welding can be dangerous to operators anywhere, so appropriate protective measures must be taken when welding. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation.

[0003] Currently, the welding of irregular-shaped pipe fittings is mostly done by manual docking. However, this method may result in deviations during manual docking, leading to substandard welding quality and rendering the irregular-shaped pipe fittings unusable. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a welding device and welding method for irregularly shaped pipe fittings. The method uses a support column and a fixed column, with the support column being fixed and the fixed column being movable, allowing for adjustment of the position and angle of the fixed column. The support column first fixes the irregularly shaped pipe fitting, and after fixation, the fixed column further fixes it. Therefore, regardless of the shape of the irregularly shaped pipe fitting, it can be fixed, facilitating welding and avoiding the inability to fix the irregularly shaped pipe fitting during welding. By mounting the welding head of the laser welding machine on a fixed ring and using an electric slide to drive the welding head to move around the inner circumference of the fixed ring, welding is completed in one rotation. This results in high welding efficiency and avoids welding difficulties caused by the shape of the irregularly shaped pipe.

[0005] The present invention also provides a welding device having the above-mentioned irregular pipe fitting, comprising: a base plate, a support seat movably connected to the upper surface of the base plate, a plurality of support columns movably connected to the upper surface of the support seat, a fixed column rotatably connected to the upper surface of the support seat, a fixed clamp fixedly connected to the upper surface of each support column and the fixed column, a movable clamp slidably connected to the upper surface of each support column and the fixed column, a top positioning device provided on the outer surface of each support column and the fixed column, the top positioning device being fixedly connected to the movable clamp, the plurality of support columns and the fixed column being connected by elastic elements, and a sliding connection on the support seat... The base plate is equipped with multiple baffles, which are movably connected to the support columns. A fixing device is installed on each baffle. A lifting device is slidably connected to the upper surface of the base plate. A telescopic device is fixedly connected to the upper surface of the lifting device. A laser welding machine is mounted on the telescopic device. A fixing ring is fixedly connected to the outer surface of the laser welding machine. The fixing ring has a cross-section that is only three-quarters the circumference of a circle. An electric slide is slidably connected to the outer surface of the fixing ring. The electric slide is fan-shaped, and its circumference is one-quarter the circumference of the fixing ring. The welding head of the laser welding machine is fixedly connected to the electric slide.

[0012] A welding method for irregularly shaped pipe fittings includes the following steps: S1. Take the irregular-shaped pipe fitting. The worker holds the irregular-shaped pipe fitting close to the fixed column so that the irregular-shaped pipe fitting fits against the outer surface of the fixed column. Then push the irregular-shaped pipe fitting so that it hits the blocking plate. S2. Press down on the movable clamp to fix the irregular pipe fitting. Then, connect the two irregular pipe fittings at the welding points. After the connection is completed, fix the irregular pipe fittings at the welding points using the fixing device.

Adjust the height of the telescopic device through the lifting device, and then adjust the position of the laser welding machine so that the part of the irregular pipe to be welded enters the inside of the fixed ring. The welding head of the laser welding machine moves with the electric slide table and completes the welding.

[0013] Compared with existing technologies, the welding equipment and method for this irregular pipe fitting utilizes a support column and a fixed column. The support column is fixed, while the fixed column is movable, allowing for adjustment of the position and angle of the fixed column. The support column first fixes the irregular pipe fitting, and after fixation, the fixed column further fixes it. Therefore, regardless of the shape of the irregular pipe fitting, it can be fixed, facilitating welding and avoiding the inability to fix the irregular pipe fitting during the welding process.
