Description

Technical Field

[0002] The long tube rolling forming machine, a type of plate rolling machine, is mainly used for rolling and forming long tubes. It's a device that uses work rollers to bend and shape sheet metal, producing cylindrical, conical, and other shapes. It's a very important processing equipment. The working principle of a plate rolling machine is that external forces such as hydraulic pressure and mechanical force cause the work rollers to move, thereby bending or rolling the sheet metal into shape. Depending on the rotation and position changes of the work rollers, elliptical, arc-shaped, and cylindrical parts can be produced.

[0027] like Figure 4 As shown, the discharge side support 4 includes a fixed base 401, a pressure frame 402, and a tilting cylinder 403. The bottom of the fixed base 401 is connected to the chassis 1. One side of the pressure frame 402 is rotatably connected to one side of the top of the fixed base 401 via a rotating shaft 406. A second pin cylinder 404 is provided on the other side of the top of the fixed base 401.

[0028] like Figure 5 As shown, the roller support device 5 includes a fourth hydraulic cylinder 501 and rollers 502. The bottom of the fourth hydraulic cylinder 501 is connected to the chassis 1. The piston rod of the fourth hydraulic cylinder 501 is equipped with two rollers 502 through the mounting bracket. The lower roller 9 is supported on the rollers 502. Because it is a slender tube, the lower roller 9 is relatively long. The support of the rollers 502 greatly improves the support of the lower roller 9, thereby ensuring the stability of the lower roller 9.

[0029] Working Method and Operating Principle: During installation, a groove can be cut in the ground, and the chassis 1 is installed in the groove. This allows for the installation of a conveying device on one side of the groove, facilitating the loading of metal sheets. First, the metal sheet is horizontally fed into the chassis 1 via the support of the feeding frame 25, resting on the lower roller 9 and below the upper roller 8. Then, the lower roller 9 is raised and lowered by the second hydraulic cylinder 18, while the side rollers 13 on both sides are moved by the side cylinders 21. This clamps the sheet between the upper roller 8, lower roller 9, and side rollers 13. The winding diameter of the sheet is controlled by the coordination of four rollers: one upper roller 8, one lower roller 9, and two side rollers 13. The first motor 17 and the second motor 24 are started. The first motor 17 drives the upper roller 8 to rotate, and the second motor 24 drives the lower roller 9 to rotate, thus winding the sheet into shape. During the forming process, the first hydraulic cylinder 16 inside the pressure beam 6 drives each set of pressure rollers 7 to press against the upper surface of the coil tube, reducing the amount of reverse deformation compensation on both sides of the upper roller 8, satisfying the rolling process requirements, and ensuring the stable performance of the upper roller 8. After the tube is formed, the piston rod of the first hydraulic cylinder 16 retracts, the pressure roller 7 rises and disengages from the tube, the piston rod of the first pin cylinder 15 retracts, causing the piston rod of the first pin cylinder 15 to disengage from the extension frame 14, the piston rod of the tilting cylinder 403 of the discharge side bracket 4 retracts, causing the pressure frame 402 to rotate around the rotating shaft 406, opening the pressure frame 402, activating the pushing cylinder 11, the piston rod of the pushing cylinder 11 moves outward, and pushes the tube along the upper roller 8 outward through the push plate 12 until the outer end of the tube is supported on the V-shaped roller 28, and the V-shaped roller 28 is driven by the third motor 29 to drive the tube outward. This utility model has a reasonable structure. A pressure beam 6 is set at the top, and multiple first hydraulic cylinders 16 are set at the bottom of the pressure beam 6. Each first hydraulic cylinder 16 is equipped with two pressure rollers 7 through a mounting frame. During the forming process, the pressure rollers 7 press against the upper surface of the rolled tube to reduce the amount of reverse deformation compensation on both sides of the upper roller 8, which meets the requirements of the rolling process and ensures the stable performance of the upper roller 8. Moreover, the height of each group of pressure rollers 7 is controlled by the first hydraulic cylinder 16 to avoid different stress conditions at each pressure roller 7 due to mechanical structure precision issues. A pusher cylinder 11 is set between the upright frame 2 and the fixed support 3 on the chassis 1. The discharge side support 4 is an openable structure. Through the cooperation of the pusher cylinder 11 and the push plate 12, the rolled tube can be easily discharged, saving labor costs and improving efficiency. Several support roller devices 5 are also set on the upper surface of the chassis 1. The lower roller 9 is supported on the support rollers 502 of the support roller devices 5, thereby ensuring the support and stability of the lower roller 9.

[0030] Each hydraulic cylinder and oil cylinder is connected to the hydraulic station through a valve, thereby achieving control.

[0031] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0032] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
