Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipes, and more specifically relates to a splash-proof protective cover for a welding machine. Background Art

[0002] Currently, most factories use automatic welding machines when producing straight seam welded pipes. The automatic welding machine is equipped with a movable welding cantilever with a connecting block on the welding cantilever. The welding gun is installed on the connecting block. During operation, the welding cantilever drives the welding gun through the connecting block to weld the pipe. During the welding process, spatter generated by the welding often falls on both sides of the weld groove and adheres to the welded pipe. These spatters are firmly bonded to the welded pipe and are not only difficult to clean, but also have a significant impact on the coupling of the subsequent ultrasonic (UT) automatic detection probe, resulting in probe coupling alarms and the inability to perform continuous UT automatic flaw detection.

In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0024] See also Figures 1 to 3The present invention now provides a welding machine anti-splash protective cover. The anti-splash protective cover comprises a connecting frame 1, with baffles 2 symmetrically disposed on either side of the connecting frame 1. A protective space 100 is defined between the two baffles 2 and the connecting frame 1. The connecting frame 1 is connected to a connecting block 500 of the welding machine, and a welding gun 400 is placed within the protective space 100. The lower edges of the two baffles 2 are positioned close to each other, forming a clearance gap 200 corresponding to a welding groove 301. The lower ends of the two baffles 2 contact the welding pipe 300, and the welding gun 400 passes through the clearance gap 200 to weld the welding groove 301.

[0025] Compared with the prior art, the utility model provides a welding machine splash protection cover. During welding operation, the welding gun 400 is located in the protective space 100 formed by the connecting frame 1 and the baffle 2, so that the splashes generated during the welding operation will be blocked by the baffle 2 when splashing toward the two sides of the welding groove 301, thereby preventing the splashes from falling on the welding pipe 300, thereby solving the problem of spatters adhering to the welding pipe 300.

[0026] In some embodiments, see Figures 1 to 3 The above-mentioned connecting frame 1 includes a connecting frame 11 and a connecting ring 12, wherein the connecting ring 12 is located directly above the connecting frame 11, and a plurality of connecting rods 13 are provided between the connecting ring 12 and the connecting frame 11. In this embodiment, the number of connecting rods 13 is four, and the four connecting rods 13 are evenly distributed around the circumference of the connecting ring 12. The connecting rods 13 are welded to the connecting frame 11 and the connecting ring 12. A connecting hole 121 is provided on the connecting ring 12, and the connecting ring 12 can be bolted to the connecting block 500 of the welding cantilever by means of the connecting hole 121, so that the welding cantilever can drive the welding machine anti-splash protective cover provided by the new model to move along with the welding gun 400. In this embodiment, the connecting frame 11 includes two first rod bodies 111 arranged symmetrically on the left and right, and a second rod body 112 is connected between the opposite ends of the two first rod bodies 111. The connecting rod 13 is connected to the second rod body 112, and the guard plate is connected to the first rod body 111.

[0027] In some embodiments, the guard plate is hingedly connected to the first rod body 111. Specifically, a pin shaft 113 is provided at both ends of the first rod body 111. The pin shaft 113 is coaxial with the first rod body 111, and the diameter of the pin shaft 113 is smaller than the diameter of the first rod body 111. A connecting arm 21 is provided on the inner wall of the guard plate corresponding to the pin shaft 113. The end of the connecting arm 21 close to the guard plate is provided with a connecting piece 211 welded and fixed. The connecting piece 211 is attached to the guard plate and bolted to the guard plate. A transverse through hole is provided at the end of the connecting arm 21 away from the guard plate. With the help of the transverse through hole, the connecting arm 21 can be mounted on the pin shaft 113 on the same side. In this embodiment, the diameter of the transverse through hole is slightly larger than the diameter of the pin shaft 113, so that the connecting arm 21 can rotate in the vertical plane around the pin shaft 113. In application, the guard plate can be driven to rotate around the first rod body 111 by rotating the connecting arm 21, so that the distance between the lower edges of the two guard plates can be adjusted, that is, the size of the clearance gap 200 can be adjusted, so that the welding machine anti-splash protective cover provided by the new model can still be applicable after the width of the welding groove 301 changes.

[0028] In this embodiment, a locking component for limiting the rotation of the baffle 2 is provided on the connecting frame 1. Specifically, the locking component is a locking nut 5 threadedly connected to the pin 113. The locking nut 5 is located on the side of the connecting arm 21 away from the first rod 111. By rotating the locking nut 5 to move it toward the first rod 111 and pressing the connecting arm 21, the connecting arm 21 can be fastened between the locking nut 5 and the first rod 111, thereby limiting the rotation of the connecting arm 21. When it is necessary to rotate the connecting arm 21, the locking nut 5 is rotated in the opposite direction to move the locking nut 5 toward the side away from the first rod 111 and away from the connecting arm 21. This releases the fastening of the connecting arm 21, allowing the connecting arm 21 to rotate freely.

[0029] In some embodiments, an anti-slip structure is provided on the end surfaces of the connecting arm 21 and the first rod body 111 that are close to each other. In this embodiment, the anti-slip structure is a rough surface provided on the connecting arm 21 and the first rod body 111. The two rough surfaces are arranged opposite to each other. When the connecting arm 21 is tightened, the two rough surfaces are in contact, and the friction force generated between the two rough surfaces can limit the rotation of the connecting arm 21.

[0030] In some embodiments, a fire-resistant insulating component 3 is coated on the lower edge of the baffle 2. Optionally, the fire-resistant insulating component 3 is asbestos. In actual applications, the baffle 2 is a galvanized metal plate. The asbestos is fixed to the baffle 2 by rivets. During welding, the asbestos contacts the welding pipe 300, and the welding pipe 300 is isolated from the baffle 2 by the asbestos, thereby avoiding the occurrence of an arc between the baffle 2 and the welding pipe 300.

[0031] In some embodiments, a plurality of ridges 4 are provided on the inner side wall of the baffle 2 in the direction in which the clearance gap 200 extends. The plurality of ridges 4 are distributed in the lower half of the baffle 2 and are spaced apart from each other. The height of the ridges 4 is 2-3 mm. In application, some spatters falling on the baffle 2 will slide down along the inner side wall of the baffle 2 into the welding groove 301 after cooling. In this embodiment, by providing the ridges 4, the sliding spatters are blocked, thereby preventing the spatters from sliding into the welding groove 301.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
