Technical Field

[0001] The utility model relates to the technical field of steel beam welding and forming, in particular to an adaptive seamless pressing device for steel beam welding and forming. Background Art

[0002] During the welding process of the steel beam, the flange and the web need to be assembled in the center, and then the connection seam between the flange and the web needs to be welded.

[0003] In order to ensure that the web and the wing plate are pressed together to reduce the contact gap between them, a clamping device is usually required to apply a certain amount of pressure to the web during welding assembly. For example, Chinese patent CN206998157U discloses a steel beam forming clamping device, including a movable crossbeam that can move up and down in the longitudinal direction, a pressure wheel mounting groove is provided on the movable crossbeam, a web pressure wheel is rotatably installed in the pressure wheel mounting groove, and the web pressure wheel is driven up and down by the movable crossbeam. The web pressure wheel is pressed on the assembled plate body to press the assembled web and wing plate to be welded. The clamping device has the following technical problems during use: the pressing contact surface between the web pressure wheel and the plate body is small. When the web or wing plate is irregular in size or warped, the contact gap between the web and the wing plate when pressed together is still large, thereby affecting the quality and efficiency of welding forming. Utility Model Content

[0006] As a preferred technical solution, a pressing force automatic adjustment mechanism is provided between the driven wheel and the mounting seat.

[0007] As a preferred technical solution, the mounting seat includes a main pressure wheel support plate and a main pressure wheel mounting ear, and the main pressure wheel is rotatably mounted on the main pressure wheel mounting ear.

[0008] As a preferred technical solution, the automatic adjustment mechanism of the pressing force includes a disc spring pressure plate, a disc spring support plate, a disc spring fixed shaft and a disc spring. The disc spring fixed shaft is installed between the disc spring pressure plate and the disc spring support plate. The disc spring is mounted on the disc spring fixed shaft. The disc spring pressure plate and the disc spring support plate are fixedly connected to the main pressure wheel support plate through disc spring pressing bolts.

[0009] As a preferred technical solution, a slave pressure wheel mounting ear is fixedly mounted on the lower portion of the disc spring support plate, and the slave pressure wheel is rotatably mounted on the slave pressure wheel mounting ear.

[0010] As a preferred technical solution, a reinforcing rib is fixedly provided on the main pressure wheel support plate.

[0011] Due to the adoption of the above technical solution, the utility model has at least the following beneficial effects:

[0012] (1) The multi-point arrangement of the main pressing wheel and the two front and rear secondary pressing wheels effectively increases the pressing contact surface between the pressing wheel and the plate body, thereby reducing the contact gap between the web and the wing plate during pressing, which is beneficial to improving the welding forming quality.

[0013] (2) The disc spring can automatically adjust the pressing force between the pressure wheel and the plate body, which can avoid the problem of conveying jam caused by excessive pressure on the plate body when the downward pressure is too large, which is beneficial to improving production stability.

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figure 1 As shown, the self-adaptive seamless pressing device for steel beam welding forming comprises a mounting seat 10, a main pressing wheel 20 is mounted in the middle of the mounting seat 10, and a secondary pressing wheel 30 is mounted at the front and rear ends of the mounting seat 10, respectively, and the secondary pressing wheel 30 and the main pressing wheel 20 are located on the same motion track. Figure 2 and Figure 3When in use, the device is fixedly connected to the movable crossbeam 40 on the assembly welding and straightening machine through the mounting seat 10. When T-shaped steel or H-shaped steel is assembled and welded, the multi-point setting of the main pressure wheel 20 and the front and rear two slave pressure wheels 30 can effectively increase the pressing contact surface between the pressure wheel and the plate body, thereby reducing the contact gap between the web 61 and the wing plate 62 when pressed, which is beneficial to improving the welding forming quality.

[0020] refer to Figure 1 In this embodiment, the mounting seat 10 includes a main pressure wheel support plate 11 and a main pressure wheel mounting ear 12. The main pressure wheel support plate 11 can be fixed to the moving cross beam 40 by bolts 14. Four reinforcing ribs 13 are fixedly arranged on the main pressure wheel support plate 11. After installation, the reinforcing ribs 13 are pressed against both sides of the moving cross beam 40 in pairs to improve the overall strength. The main pressure wheel 20 is rotatably mounted on the main pressure wheel mounting ear 12 through a rotating shaft and a bearing. During operation, a certain pressure is applied to the plate body through the main pressure wheel 20 to ensure that the web and the wing plate are kept relatively pressed against each other, thereby facilitating welding.

[0021] An automatic pressing force adjustment mechanism 50 is provided between the driven wheel 30 and the mounting seat 10. In this embodiment, the automatic pressing force adjustment mechanism 50 comprises a disc spring pressure plate 51, a disc spring support plate 52, a disc spring fixed shaft 53 and a disc spring 54, wherein the disc spring fixed shaft 53 is installed between the disc spring pressure plate 51 and the disc spring support plate 52, and the disc spring 54 is sleeved on the disc spring fixed shaft 53. The disc spring pressure plate 51 and the disc spring support plate 52 are fixedly connected to the main pressure wheel support plate 11 through disc spring pressing bolts 55, and a slave pressure wheel mounting ear 56 is fixedly installed at the lower part of the disc spring support plate 52, and the slave pressure wheel 30 is rotatably mounted on the slave pressure wheel mounting ear 56 through a rotating shaft and a bearing. In this way, after the disc spring 54 is compressed and deformed between the disc spring pressure plate 51 and the disc spring support plate 52, it will store a certain potential energy to provide a certain downward pressure to the slave pressure wheel 30; when the plate body is irregular in size or warped, the disc spring 54 can automatically adjust the pressing force between the slave pressure wheel and the plate body, thereby avoiding the problem of conveying jams caused by excessive pressure on the plate body, which is beneficial to improving production stability.

[0022] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
