[0016] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0017] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", etc. indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0018] As shown in Figs. 1 to 3 The utility model provides a disc shears intermediate joist, the disc shears intermediate joist is located at the center of disc shears frame, the disc sheares intermediate joist includes upright post frame 1 and the middle section supporting plate 2 set on the upper end surface of upright post frame 1, the upright post frame 1 is installed on the moving beam below the disc shears, the middle section supporting plate 2 is uniformly provided with a plurality of supporting wheels 3 on the upper end surface along the advancing direction of steel plate, the front and rear ends of the middle section supporting plate 2 are provided with the shearing front roller way supporting plate 4 and the shearing rear roller way supporting plate 5 respectively, the shearing front roller way supporting plate 4 and the shearing rear roller way supporting plate 5 are respectively connected with the roller way at the front and rear ends of the disc shears. Specifically, the distance between the butt joint end of the shearing front roller way supporting plate 4 and the front end roller way of the disc shears is less than or equal to 80mm; the distance between the butt joint end of the shearing rear roller way supporting plate 5 and the rear end roller way of the disc shears is less than or equal to 80mm.

[0019] Further, the shearing front roller way supporting plate 4 and the shearing rear roller way supporting plate 5 are both inclinedly arranged, and the included angle between the shearing front roller way supporting plate 4 and the shearing rear roller way supporting plate 5 and the middle section supporting plate 2 is an obtuse angle. The inclinedly arranged shearing front roller way supporting plate 4 and shearing rear roller way supporting plate 5 can better guide the steel plate to enter and leave the disc shears stably. This design helps to reduce the shaking and deviation of the steel plate during shearing, ensures that the steel plate can be sheared along the predetermined path, and thus improves the shearing precision and stability. Specifically, the butt joint end of the shearing front roller way supporting plate 4 is 80mm lower than the elevation of the front roller way of the disc shears. The shearing front roller way supporting plate 4 provides a gradually rising transmission path for the steel plate. This design reduces the impact of the head of the steel plate on the disc shears intermediate joist, making it more stable to enter the shearing area. The butt joint end of the shearing rear roller way supporting plate 5 is 50mm lower than the elevation of the rear roller way of the disc shears. The design of the shearing rear roller way supporting plate 5 provides a gentle descending channel for the steel plate, so that the steel plate can enter the shearing rear roller way stably after leaving the disc shears. This design helps to reduce the shaking or jolting of the steel plate after entering the shearing rear roller way, improving the shearing quality.

[0020] Further, the pre-cutting roller table support plate 4 and the post-cutting roller table support plate 5 are respectively welded with the middle section support plate 2, and the lower end surface of the post-cutting roller table support plate 5 is supported on the roller base 7 through the stand column 6. The connection between the pre-cutting roller table support plate 4, the post-cutting roller table support plate 5 and the middle section support plate 2 is firm and reliable. The design makes the whole support beam structure more stable when bearing the weight of the steel plate and the shearing force, and is not easy to deform or loosen.

[0021] When the intermediate support beam of the disc shear is installed, the intermediate support beam of the disc shear is hoisted to the middle of the disc shear frame, placed on the moving beam below the disc shear and aligned with the bolt eye. When the shearing width of the disc shear is adjusted, the disc shear frame and the moving beam below the disc shear are driven through the lead screw, and the moving distance of the moving beam is just half of the moving distance of the frame. The intermediate support beam of the disc shear is ensured to be located in the middle position of the disc shear frame.

[0022] When the steel plate is sheared, the edge of the steel plate is sheared by the disc shear blade, and the steel plate is in a stressed state. The pressure of the steel plate on the middle section support plate 2 will be higher than the gravity of the steel plate due to the shearing deformation. The carrier wheels 3 arranged on the middle section support plate 2 effectively support the steel plate and make the movement of the steel plate more smooth. After the steel plate is sheared, it is moved to the post-cutting roller table through the middle section support plate 2, and the head of the steel plate is borrowed to the post-cutting roller table support plate 5. The elevation of the post-cutting roller table support plate 5 is close to the elevation of the post roller, so the steel plate can smoothly enter the roller and solve the problem of the head being stuck in the gap between the middle section support plate 2 and the roller.

[0023] Thanks to the above technical scheme, the steel plate can maintain a flat and stable state during shearing operation, and a comprehensive and balanced support system is provided for the steel plate, thereby effectively avoiding the deformation or warping of the steel plate during shearing.

[0024] A plurality of carrier wheels 3 are evenly arranged on the middle section support plate 2 along the advancing direction of the steel plate, which can flexibly adapt to steel plates of different widths and thicknesses, and ensure that the steel plate always maintains a flat state during shearing; the pre-cutting roller table support plate 4 and the post-cutting roller table support plate 5 are respectively connected with the rollers at the front and rear ends of the disc shear, so that the steel plate can smoothly enter and leave the disc shear, avoiding the shearing quality problems caused by the shaking or jumping of the steel plate.

[0025] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
