Problems solved by technology
[0002] Usually, in the process of producing the air cushion table at the cold end of the glass production line, because the main body of the air cushion table is welded by thin-walled rectangular tubes, there are many welds, and they are all concentrated on one side of the rectangular tube, and the air cushion table will appear after welding. The upper plane is bent and deformed, and the maximum deformation can reach 20mm. The design requires that the flatness of the air cushion table must be controlled within the range of 0-2mm. The middle part of the thin-walled rectangular tube is baked with flame, and then the baked part is cooled with water, so that the thin-walled rectangular tube cools and shrinks to the opposite side, thereby correcting the plane. This method has the disadvantage that the amount of correction deformation is not easy to control, and the thin-walled rectangular tube shrinks unevenly. , the flatness after correction is poor, and the correction work requires a lot of experience and repeated corrections, which takes a long time

Embodiment Construction
[0018] Referring to the accompanying drawings, a process for calibrating an air cushion table with pressure, water and fire, the specific steps are as follows:
[0019] (1), prepare to first take two air cushion tables A and B to be calibrated, prepare two jacks 1 and four wire rope sets 2;
[0020] (2) Preloading Place the air cushion table B horizontally, the air cushion table A is inverted and correspondingly located directly above B, and the jacks 1 are respectively placed on the upper end surface of the middle part of the small thin-walled rectangular tube 4 at the two outer ends of the large rectangular tube 3 of the air cushion table B, The protruding ends of the ejector rods of the jack 1 are pushed against the lower end surfaces of the small thin-walled rectangular tubes 4 of the inverted air cushion table A, and at the same time, the ends of the corresponding upper and lower small thin-walled rectangular tubes 4 are connected together with wire ropes. Then place the ...

The invention discloses a process for correcting air table by pressure, water and fire. The process includes the particular steps: preparing, prepressing, heating, baking and then cooling small thin-walled rectangular tubes by cooling water to reach the room temperature to finish first-step correction; correcting other small thin-walled rectangular tubes of the air table sequentially by preparing, prepressing, heating, baking and then cooling the other small thin-walled rectangular tubes; removing a steel wire rope sleeve to observe planeness of upper planes of the rectangular tubes after correcting all the rectangular tubes; and continuing correcting the rectangular tubes again or repeatedly in similar modes if the planeness of the upper planes does not meet requirements until correcting the planeness. By the pressure, the water and the fire, the upper plane of the air table is smoothly corrected by reasonably applying pressure, correctly selecting bending points, heating and fast cooling, design requirements are met, and the process is reliable.
Description
technical field [0001] The invention relates to a manufacturing process of an air cushion table at the cold end of a glass production line, and belongs to the field of glass machinery. In particular, it relates to a technique for calibrating an air cushion table with pressure, water and fire. Background technique [0002] Usually, in the process of producing the air cushion table at the cold end of the glass production line, because the main body of the air cushion table is welded by thin-walled rectangular tubes, there are many welds, and they are all concentrated on one side of the rectangular tube, and the air cushion table will appear after welding. The upper plane is bent and deformed, and the maximum deformation can reach 20mm. The design requires that the flatness of the air cushion table must be controlled within the range of 0-2mm. The middle part of the thin-walled rectangular tube is baked with flame, and then the baked part is cooled with water, so that the thin...
