[0040] See also Figure 1 As shown, the present embodiment provides a method for producing a right-angle elbow guide vane, comprising the following steps: preparing a connecting plate 500 and a blade 600 in a guide vane 600 according to the caliber size of the right-angle elbow; performing a zinc layer removal treatment on both ends of the blade 600 and the connecting plate 500; performing an arc pressing treatment on the blade 600, and performing a flanging treatment on the two side edges of the connecting plate 500, so that the connecting plate 500 has a connecting groove for accommodating the blade 600; placing the connecting plate 500 and the blade 600 in a welding production mold for welding, and temporarily setting a positioning pad 400 between two adjacent blades 600; after each blade 600 is welded, the welding point is polished clean, and after all welding is completed, the guide vane 600 is sent as a whole to the anti-corrosion area, and the damaged galvanized part is painted.

[0041] Specifically, the connecting plate 500 and the blade 600 in the guide vane 600 are prepared, and then the two ends of the blade 600 and the connecting plate 500 are treated to remove the zinc layer, and then the two connecting plates 500 are installed in the positioning grooves of the welding production mold, and then the blade 600 is placed in the connecting groove of the connecting plate 500, and a plurality of positioning pads 400 are placed under the blade 600 to ensure the flatness of the blade 600, and then the blade 600 and the connecting plate 500 are welded. After the welding is completed, the weld of this blade 600 is polished, and then a plurality of positioning pads 400 are placed above the blade 600, and then the second blade 600 is placed on the plurality of positioning pads 400, and the second blade 600 and the connecting plate 500 are welded. Through such an arrangement, the spacing between adjacent blades 600 can be guaranteed, and at the same time, the straightness of the blade 600 after welding can be guaranteed. After all the welding is completed, the guide vane 600 is sent to the anti-corrosion area as a whole, and the damaged galvanized part is painted.

[0042] The curvature of the blade 600 is 90 degrees, and the blade 600 can be produced by using a press-bending forming device to ensure the straightness of the blade 600.

[0043] The two sides of the connecting plate 500 are each flanged by 13 mm. In addition, those skilled in the art can adjust the flange size of the connecting plate 500 according to actual needs, which is not described here.

[0044] The spacing distance between two adjacent blades 600 is 38±1 mm. By setting the positioning pad 400, the spacing accuracy between two adjacent blades 600 is controlled within 38±1 mm, thereby ensuring the overall use effect of the guide blade 600.

[0045] The blade 600 and the connecting plate 500 are welded by double-sealed welding.

[0046] Among them, the current of the two-way welding is set between 110-120A, the voltage is set between 12-18V, and the welding speed is set between 7-18cm / min. For example, the current of the two-way welding is set to 110A, the voltage is set to 12V, and the welding speed is set to 7cm / min, or the current of the two-way welding is set to 120A, the voltage is set to 12V, and the welding speed is set to 7cm / min, or the current of the two-way welding is set to 115A, the voltage is set to 15V, and the welding speed is set to 18cm / min, or the current of the two-way welding is set to 120A, the voltage is set to 18V, and the welding speed is set to 18cm / min.

For example, the repair thickness of the damaged galvanized layer is 50 um, or the repair thickness of the damaged galvanized layer is 70 um, or the repair thickness of the damaged galvanized layer is 90 um, or the repair thickness of the damaged galvanized layer is 100 um.

[0048] See also Figure 1 As shown, this embodiment provides a welding production mold for a right-angle elbow guide blade production method, including: a fixed bracket 100, a movable bracket 200 and a slide seat 300; both ends of the fixed bracket 100 are connected to the slide seat 300, and the slide seat 300 is perpendicular to the fixed bracket 100; both ends of the movable bracket 200 can be slidably arranged in the slide seat 300, and the fixed bracket 100 and the movable bracket 200 have positioning grooves for positioning the connecting plate 500.

[0049] The method for producing the right-angle elbow guide vane further includes a positioning pad 400, which is placed between two adjacent blades 600 so that the distance between the two adjacent blades 600 is controlled within a set range.

[0050] The slideway seat 300 is provided with a locking member 310 for locking the movable bracket 200. The locking member 310 can be made of angle steel.

[0051] Specifically, one side of the welding production mold is a fixed bracket 100, and the other side is a movable bracket 200. Both brackets have positioning grooves for positioning the connecting plates 500. During the welding process, the staff inserts the two connecting plates 500 into the positioning grooves of the fixed bracket 100 and the movable bracket 200 respectively, and then puts the blade 600 between the two connecting plates 500. Then, the movable bracket 200 is moved and positioned on the slide seat 300 according to the length of the blade 600, so that the two connecting plates 500 can be tightly abutted against the blade 600. After the positioning is completed, the movable bracket 200 and the slide seat are locked by using the locking member 310. 300 is fixed to prevent the mobile bracket 200 from shifting, and then a plurality of positioning pads 400 are placed under the blade 600, one side of the positioning pad 400 is in contact with the blade 600, and the other side is in contact with the slide seat 300, so as to complete the positioning of the first blade 600, and then the connection between the first blade 600 and the connecting plate 500 is spot welded, and then full welded, and after welding, the welding slag is polished and cleaned, and then the positioning pad 400 is moved to the first blade 600, and then the second blade 600 is placed for welding, and so on, until all the blades 600 are welded to the connecting plate 500. Through such a setting, the relative position of the blade 600 and the connecting plate 500 after welding can be controlled to ensure the straightness of the blade 600 and the gap between adjacent blades 600.

[0052] Wherein, positioning slot plates 110 are disposed on both the fixed bracket 100 and the movable bracket 200 , and a plurality of positioning slot plates 110 cooperate to form a positioning slot.
