Description

Technical Field

[0001] The present application relates to the technical field of thick plate bending, and in particular to a thick plate bending structure. Background Art

[0002] Thick plate bending is an important process in the field of metal processing. It is mainly used to bend thicker metal plates according to specific angles and shapes. This process is widely used in the construction, shipbuilding, automobile, aviation, machinery and other industries to manufacture various structural parts and components.

[0003] There are two main ways to bend thick plates. One is to use an extended section as an auxiliary end, bend it into shape through a bending machine, and then cut it. The other is to mill the thick plate on the inside of the bend.

[0004] The use of the extended section as the auxiliary end is limited by the parts that are formed continuously in multiple passes. The secondary cutting causes deviations in the positioning dimensions, and the internal angle arc cannot be controlled to the minimum after bending. The method of milling the thick plate on the inner side of the bend has the phenomenon of bending tool clamping. The milling area of ​​the forming structure is relatively large, which is also limited by the parts that are formed continuously in multiple passes, resulting in double-sided transition milling. The above two thick plate bending methods result in poor bending effects and affect the forming efficiency of thick plate bending. Summary of the invention

[0005] In order to help solve the problem that the existing method of bending thick plates leads to poor bending effect and affects the forming efficiency of the thick plate bending, the present application provides a thick plate bending structure, which adopts the following technical solution: it includes a thick plate body, and a bending groove is opened on the thick plate body, and the bending groove is located on the inner side of the bending part of the thick plate body.

[0006] Through the above technical scheme, the setting of the bending groove is utilized to reduce the pressure required for bending the thick plate, and at the same time, it is convenient to lean on the stopper, which provides positioning, support and stabilization in the bending process, thereby ensuring the accuracy and consistency of the bending operation of the thick plate body, thereby improving the overall quality of the bending forming of the thick plate body. While having strong fastness, the thick plate body is easy to form in one time after being bent through the bending groove, thereby improving the forming efficiency of the thick plate bending.

[0007] In a specific possible implementation scheme, the bending groove includes a transition groove opened on the inner side of the bending part of the thick plate body, and an inclined groove is opened at the bottom of the transition groove.

[0008] Through the above technical scheme, by setting the transition groove and the inclined groove on the bending groove, the pressure provided by the bending machine when the thick plate body is bent can be reduced, thereby reducing the load of the bending machine, thereby improving the overall quality of the bending forming of the thick plate body. While the fastening is strong, the thick plate body is easy to form in one time after being bent through the bending groove, thereby improving the forming efficiency of the thick plate bending.

[0009] In a specific possible implementation manner, the groove bottom of the inclined groove is provided with a transition angle.

[0010] Through the above technical solution, the transition angle reduces the stress concentration of the inclined groove and improves the bending strength and torsional strength of the thick plate body.

[0011] In a specific possible implementation manner, the transition angle is a circular chamfer.

[0012] Through the above technical solution, the arc chamfer can eliminate sharp angles and disperse stress, thereby effectively improving the durability of the thick plate body.

[0013] In a specific implementation manner, the arc chamfer has an arc angle greater than 3 mm.

[0014] Through the above technical solution, the circular chamfer with a larger radius can more effectively eliminate sharp angles, disperse the stress over a larger area, further reduce the stress concentration phenomenon, thereby improving the durability of the thick plate body and significantly improving the bending strength and torsional strength of the thick plate body.

[0015] In a specific possible implementation manner, a bevel is provided at the notch of the transition groove.

[0016] Through the above technical solution, the bevel plays an avoidance role, reducing the possibility of interference between external equipment or tools and the thick plate body, making it easier for the thick plate body to be formed in one step after being bent through the bending groove, thereby improving the forming efficiency of the thick plate bending.

[0017] In a specific implementation manner, the width of the transition groove is not less than 3 times the thickness of the thick plate body.

[0018] In a specific possible implementation manner, the depth of the bending groove does not exceed half of the thickness of the thick plate body.

[0019] In a specific possible implementation manner, the thick plate body is made of metal material.

[0020] In a specific possible implementation manner, the thick plate body is made of steel material.

[0021] To sum up, the present application has at least the following beneficial technical effects: the setting of the bending groove is utilized to reduce the pressure required for bending the thick plate, while facilitating the use of a stopper, which provides positioning, support and stabilization in the bending process, thereby ensuring the accuracy and consistency of the bending operation of the thick plate body, thereby improving the overall quality of the thick plate bending forming. While having strong fastening, the thick plate body is easy to form in one step after being bent through the bending groove, thereby improving the forming efficiency of the thick plate bending.

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses a thick plate bending structure.

[0027] Reference Figure 1 and Figure 2 The thick plate bending structure includes a thick plate body 1. The thick plate can be made of metal material. In the embodiment of the present application, the thick plate body 1 is made of steel material. When the steel thick plate body 1 is subjected to external force, plastic deformation will occur, that is, the shape will change without breaking or crushing, and it has high strength and good load-bearing capacity.

[0028] Reference Figure 1 and Figure 2 A bending groove 2 is provided at the center of the thick plate body 1, and the bending groove 2 is located inside the bending part of the thick plate body 1. The bending groove 2 includes a transition groove 3 provided inside the bending part of the thick plate body 1, and an inclined groove 4 is provided at the bottom of the transition groove 3. Therefore, by setting the transition groove 3 and the inclined groove 4 on the bending groove 2, the pressure provided by the bending machine when the thick plate body 1 is bent can be reduced, thereby reducing the load of the bending machine, thereby improving the overall quality of the bending forming of the thick plate body 1, and the thick plate body 1 is easy to form once after being bent through the bending groove 2, thereby improving the forming efficiency of the thick plate bending.

[0029] Reference Figure 1 and Figure 2 , the bottom of the inclined groove 4 is provided with a transition angle 5, and the transition angle 5 in the embodiment of the present application adopts a circular chamfer and the arc of the circular chamfer is greater than 3mm. Therefore, the transition angle 5 reduces the stress concentration of the inclined groove 4, improves the bending strength and torsional strength of the thick plate body 1, and the circular chamfer can eliminate sharp angles and disperse stress, thereby effectively improving the durability of the thick plate body 1. The circular chamfer with a larger radius can more effectively eliminate sharp angles, disperse stress over a larger area, further reduce stress concentration, thereby improving the durability of the thick plate body 1, significantly improving the bending strength and torsional strength of the thick plate body 1, and ensuring the rigidity and strength of the thick plate body 1 after bending.

[0030] Reference Figure 1 and Figure 2The transition groove 3 can be provided with an oblique opening at the notch according to actual conditions. The oblique opening plays a role of avoidance, reduces the possibility of interference between external equipment or cutting tools and the thick plate body 1, facilitates the one-time forming of the thick plate body 1 after being bent through the bending groove 2, effectively prevents the cutting tool from being clamped, and improves the forming efficiency of the thick plate bending.

[0031] Reference Figure 1 and Figure 2 In order to facilitate the bending of the thick plate body 1 while ensuring the connection strength at the bending point, the width of the transition groove 3 is not less than 3 times the thickness of the thick plate body 1, and the depth of the bending groove 2 is not more than half the thickness of the thick plate body 1.

[0032] The implementation principle of the embodiment of the present application is: utilizing the setting of the bending groove 2 to reduce the pressure required for bending the thick plate, while facilitating the backstop, which provides positioning, support and stabilization in the bending process, ensuring the accuracy and consistency of the bending operation of the thick plate body 1, thereby improving the overall quality of the bending and forming of the thick plate body 1. While having strong fastness, the thick plate body 1 is convenient for one-time forming after being bent through the bending groove 2, which can reduce the extrusion of the inner corners at the bending point of the thick plate body 1, thereby facilitating subsequent reverse folding and flattening. The bent part is completely flattened to fit closely with the plane of the thick plate body 1, and the gap between the two should be less than 0.2mm, thereby improving the forming efficiency and forming quality of the thick plate bending.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
