Specific implementation manners
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0025] Please refer to Figure 1 , the present utility model discloses a bevel pipe parallel sealing and welding tooling, including a bottom plate 100, a first fixing block 200 and a second fixing block 300. Among them, the bottom plate 100 is a rectangular horizontal plate for horizontally installing the first fixing block 200 and the second fixing block 300 thereon.
[0026] Please refer to Figure 2 , the first fixing block 200 is a square block installed on the upper surface of the bottom plate 100. A first semi-circular groove 201 extending to both ends is opened along the length direction of the first fixing block 200 at the center of the upper side of the first fixing block 200. The second fixing block 300 is also installed on the upper surface of the bottom plate 100 and is arranged in parallel and spaced corresponding to the first fixing block 200; a second semi-circular groove 301 coaxial with the axis of the first semi-circular groove 201 is opened along the length direction of the second fixing block 300 at the center of the upper side of the second fixing block 300, and a U-shaped groove 303 is also opened on the upper side of the second fixing block 300. Among them, one end of the second semi-circular groove 301 close to the first fixing block 200 extends to the end of the second fixing block 300, and the other end extends to the top of the U-shaped groove 303.
[0027] Please refer to Figures 3-4, the bottom surface of the U-shaped groove 303 is perpendicular to its two side surfaces. A first triangular block 400 is non-fixedly installed in the U-shaped groove 303. The two right-angled sides of the first triangular block 400 are in contact with the bottom surface of the U-shaped groove 303 and the inner wall of one side close to the second semi-circular groove 301. An inclined groove 401 collinear with the axis of the second semi-circular groove 301 is provided on its upper side. The inclined groove 401, the second semi-circular groove 301, and the first semi-circular groove 201 have the same radius, and the three form a continuous inclined pipe placement groove. The inclined end of the inclined pipe is placed in the inclined groove 401, and the inclined degree of the inclined surface of the first triangular block 400 is the same as that of the inclined pipe. Therefore, when the inclined end of the inclined pipe is placed in the inclined groove 401, its inclined end is consistent with the inclination of the inclined groove 401.
[0028] It should be noted that the pipe diameters of the first semi-circular groove 201, the second semi-circular groove 301, and the inclined groove 401 are determined according to the pipe diameter of the inclined pipe to be welded, and are the same as the pipe diameter of the inclined pipe to be welded to ensure that the inclined pipe just fits into the groove; according to different pipe diameters of the inclined pipe to be welded, different sizes can be determined, and the specific sizes are determined according to actual needs.
[0029] At the same time, according to different inclined degrees of the inclined pipe, the inclined surface of the first triangular block 400 can be set to the corresponding inclined degree. When the inclined degree of the inclined pipe is different, only the first triangular block 400 with an inclined surface having the corresponding inclined degree needs to be replaced. Therefore, it can be applied to inclined pipes with different inclined degrees.
[0030] A second triangular block 500 is non-fixedly arranged on the upper side of the first triangular block 400. The inclined surface of the second triangular block 500 is in contact with the inclined surface of the first triangular block 400. Therefore, when the second triangular block 500 is correspondingly placed on the first triangular block 400, its inclined surface just presses the inclined pipe, and makes the inclined surface of the inclined pipe in contact with the inclined surfaces of the first triangular block 400 and the second triangular block 500. At this time, the inclined opening of the inclined pipe is facing directly upwards, so that the inclined pipe maintains a horizontal state with the inclined opening upwards.
[0031] A fixing mechanism is arranged on the upper side of the second semi-circular groove 301 for fixing the inclined pipe to the second semi-circular groove 301. The fixing mechanism includes a pressing block 600. A third semi-circular groove 601 corresponding to the second semi-circular groove 301 is provided on the lower side of the pressing block 600. The third semi-circular groove 601 and the second semi-circular groove 301 enclose a circular channel for accommodating the inclined pipe; first screw holes 302 are respectively provided at the four corners on the upper side of the second fixing block 300, and second screw holes 602 corresponding to the plurality of first screw holes 302 are provided on the pressing block 600. Fixing bolts 700 with matching threads are inserted through the corresponding first screw holes 302 and second screw holes 602. When the inclined pipe is located in the second semi-circular groove 301, the pressing block 600 can be fixed to the second fixing block 300 through the fixing bolts 700 to realize the fixation of the inclined pipe.
[0032] The bottom plate 100, the first fixing block 200, the second fixing block 300, the first triangular block 400, the second triangular block 500, and the pressing block 600 are all made of high-strength, high-temperature resistant, and corrosion-resistant graphite or stainless steel materials, having sufficient stability and heat resistance, being able to resist the high temperature generated during the welding process, and having a long service life.
[0033] The working principle of the present utility model:
[0034] During use, first place the beveled tube in the corresponding second semi-circular groove 202, the second semi-circular groove 301, and the beveled groove 401, such that the bevel of the beveled tube is located in the beveled groove 401 and the bevel is kept horizontally upward, and try to fit with the inclined surface of the beveled groove 401; then press the inclined surface of the second triangular block 500 against the inclined surface of the first triangular block 400, and make the second triangular block 500 fit with the first triangular block 400 when observing from the side, so as to ensure that the beveled tube fits with the inclined surfaces of the first triangular block 400 and the second triangular block 500, ensuring that the beveled tube is in the state where the bevel is horizontally upward at this time. Subsequently, cover the pressing block 600 on the upper side of the second fixing block 300, such that the third semi-circular groove 601 corresponds to the second semi-circular groove 301, thereby surrounding the beveled tube, and making the second screw hole 602 correspond to the first screw hole 302 one by one. Then insert the fixing bolt 700 into the corresponding second screw hole 602 and the first screw hole 302 to fix the pressing block 600 on the second fixing block 300, achieving the fixation with the inclined tube. Then the welding work can be carried out. At this time, the inclined tube is in a fixed state and will not loosen, which is beneficial to the progress of the welding work.
