Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal bending and forming technology, specifically to a reversing structure for a plate rolling machine. Background Technology
[0002] Plate rolling machines are indispensable equipment in the metal bending and forming industry. They can form parts of various shapes, such as cylindrical and conical parts, making them a crucial type of plate rolling forming equipment. The inverted body is one of the core components of the plate rolling machine's mechanical parts. To complete the bending, rolling, and unloading of the sheet metal, it requires a support point connected to the other end of the upper roller. Currently, the inverted body uses the method shown in the attached diagram of the instruction manual. Figure 1 The overall structure shown works in conjunction with other components to complete the relevant actions. During the opening, closing, and operation of the inverter, the inner bore surface of the inverter and the outer shaft surface of the upper roller bearing seat experience varying degrees of wear, resulting in high maintenance costs and long replacement cycles. At the same time, the structure effectively solves the problem of processing costs. Utility Model Content
[0003] The purpose of this utility model is to provide a reversing body structure for a plate rolling machine, in order to solve the problem mentioned in the background art that the inner hole surface of the reversing body and the outer shaft surface of the upper roller bearing seat are worn to varying degrees, resulting in high maintenance costs and long replacement cycles.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a reversing body structure for a plate rolling machine, comprising an outer body, an upper sphere, a sphere, and a lower sphere, characterized in that: the upper sphere and the lower sphere are fixedly connected to the outer body by screws; the inner surfaces of the upper sphere and the lower sphere are provided with inner spherical surfaces; the outer surface of the sphere is provided with an outer spherical surface, which cooperates with the inner spherical surfaces of the upper sphere and the lower sphere to form a rotational constraint; simultaneously, guide plates are provided on the left and right sides of the sphere to guide the reversing body to meet the upper roller and prevent relative rotation between the upper roller's copper sleeve and the sphere;
[0005] The tilting side of the tilting body is equipped with a baffle to limit the rotation angle of the ball; the lower end hole of the tilting body is connected to the oil cylinder through a pin, driving the tilting body to make an arc motion around the fixed point of the frame.
[0006] Preferably, the combined structure of the upper sphere, the sphere and the lower sphere is a spherical bearing type.
[0007] Preferably, the baffle is fixed to the outer body by screws and limits the rotation angle of the sphere.
[0008] The working process of this utility model is as follows:
[0009] In the process of the inverted body and the upper roller closing together, the inverted body moves in an arc around a fixed point on the machine frame. The baffle restricts the rotation angle of the ball due to its own weight, which facilitates the closing with the upper roller. The guide plate guides the upper roller to close with the inverted body and at the same time prevents wear on the outer diameter of the upper roller bearing seat. During the bending and forming process of the sheet metal, the flat structure provided on the inner circular surface of the ball prevents the bearing seat from rotating and causing the bearing to "creep" and at the same time prevents the inner circular surface of the ball from being ground.
[0010] The beneficial effects of this utility model are as follows:
[0011] (1) In this utility model, the upper sphere and the lower sphere are connected by the inner sphere and the outer sphere to form a joint bearing motion mechanism, thereby realizing the rotation constraint of the sphere, facilitating the connection between the head body and the upper roller, reducing wear, and extending service life.
[0012] (2) The present invention has a guide plate and a flat structure on the spherical surface inside the ball, which effectively prevents the bearing seat from rotating and causing the bearing to "creep" phenomenon, while preventing the inner spherical surface of the ball from being ground and improving the mating accuracy.
[0013] (3) The modular design of each component of this utility model facilitates replacement and maintenance, and solves the problems of high processing and manufacturing costs, high maintenance costs and long replacement cycles. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.
[0019] like Figure 1The diagram shows a reversing body structure for a plate rolling machine, comprising an outer body 1, an upper sphere 2, a sphere 3, and a lower sphere 5. The upper sphere 2 and the lower sphere 5 are fixedly connected to the outer body 1 by screws. The inner surfaces of the upper sphere 2 and the lower sphere 5 are provided with inner spherical surfaces. The outer surface of the sphere 3 is provided with an outer spherical surface, which cooperates with the inner spherical surfaces of the upper sphere 2 and the lower sphere 5 to form a rotational constraint. The combined structure of the upper sphere 2, the sphere 3, and the lower sphere 5 is a spherical bearing type. Meanwhile, guide plates 6 are provided on the left and right sides of the sphere 3 to guide the reversing body to meet the upper roller and prevent relative rotation between the upper roller's copper sleeve and the sphere 3. A baffle 4 is provided on the reversing side of the reversing body. The baffle 4 is fixed to the outer body 1 by screws and limits the rotation angle of the sphere 3. The lower end hole of the reversing body is connected to a hydraulic cylinder through a pin, driving the reversing body to perform an arc motion around the fixed point of the machine frame.
[0020] The working process of this utility model is as follows:
[0021] In the process of the inverted body and the upper roller closing together, the inverted body moves in an arc around a fixed point on the machine frame. The baffle 4 restricts the rotation angle of the ball 3 due to its own weight, which facilitates the closing with the upper roller. The guide plate 6 guides the upper roller to close with the inverted body and at the same time prevents wear on the outer diameter of the upper roller bearing seat. During the bending and forming process of the sheet metal, the flat structure provided on the inner circular surface of the ball 3 is used to prevent the bearing seat from rotating and causing the bearing to "creep" phenomenon, while preventing the inner circular surface of the ball 3 from being ground.
[0022] In this invention, the upper and lower spheres are connected by the inner spherical surface and the outer spherical surface of the sphere to form a joint bearing-type motion mechanism, thereby achieving rotational constraint of the spheres, facilitating the mating of the inverted body and the upper roller, and reducing wear. At the same time, a guide plate and a flat structure are provided on the inner spherical surface of the sphere, which effectively prevents the bearing seat from rotating and causing the bearing to "creep" phenomenon, while also preventing the inner spherical surface of the sphere from being ground and improving the mating accuracy.
[0023] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, based on the technical teachings provided by this utility model and as common knowledge in the mechanical field, other equivalent modifications and improvements can be made, and these should also be considered within the scope of protection of this utility model.
