Description

A steel plate bending device for safes Technical Field

[0001] This utility model relates to the field of safe processing technology, and in particular to a safe steel plate bending device. Background Technology

[0002] The safe's enclosure must be manufactured using steel plates. During the processing of the steel plates, they are bent into shape. However, due to the inherent metal stress of the steel plates, they spring back at a certain angle after bending, resulting in low processing accuracy and affecting subsequent processing. Furthermore, the springback angle varies depending on the thickness and material of the steel plates. A single bending and stamping method is not suitable for various processing methods. Therefore, we propose a steel plate bending device for safes. Summary of the Invention

[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Referring to Figures 1-4, a steel plate bending device for a safe includes a workbench, a fixed plate 3, a support plate 12, a limiting plate 6, a positioning plate 7, a pressure plate 10, a hydraulic cylinder 9, and a fixed seat 8. The workbench is composed of a bearing plate 1 and columns 2. The lower end of the bearing plate 1 has longitudinally arranged columns 2. One end of the bearing plate 1 has a pressure plate 10, and the lower end of the pressure plate 10 has a hydraulic cylinder 9. The lower end of the hydraulic cylinder 9 has a fixed seat 8. One end of the upper end of the bearing plate 1 has a fixed plate 3. The end of the fixed plate 3 facing the pressure plate 10 has a support plate 12. The support plate 12 has a positioning plate 7, which is hinged to the end of the support plate 12. A limiting plate 6 is provided between the positioning plate 7 and the fixed plate 3. The limiting plate 6 is located above the support plate 12 and is used to adjust the angle between the positioning plate 7 and the fixed plate 3. The angle can be adjusted according to the steel plate of different thicknesses and materials to facilitate processing.

[0019] The pressure plate 10 is hinged to the bearing plate 1. At least one hydraulic cylinder 9 is provided on the lower end face of the pressure plate 10. The upper piston rod of the hydraulic cylinder 9 is hinged to the lower end face of the pressure plate 10. The lower end of the hydraulic cylinder 9 is hinged to the fixed seat 8. The hydraulic cylinder 9 extends to fold the pressure plate 10 upward, thereby bending the steel plate.

[0020] The fixed plate 3 has connecting rods 5 symmetrically distributed on both sides. The upper end of the connecting rod 5 is rotatably connected to the side of the fixed plate 3, and the lower end of the connecting rod 5 is rotatably connected to the side of the bearing plate 1. The fixed plate 3 has a handle 4 at the end away from the positioning plate 7. Pressing down the handle 4 will press the fixed plate 3 down onto the upper surface of the steel plate to fix the steel plate. The lower end face of the fixed plate 3 is provided with an anti-slip pad. The anti-slip pad of the fixed plate 3 prevents the steel plate from moving laterally when it is bent, thereby increasing the stability of the steel plate.

[0021] The limiting plate 6 is slidably connected to the fixed plate 3. The limiting plate 6 is provided with a longitudinally arranged adjusting bolt 11. The adjusting bolt 11 passes through the limiting plate 6 and is threadedly connected to the limiting plate 6. The lower end of the adjusting bolt 11 is rotatably connected to the upper end face of the support plate 12. Rotating the adjusting bolt 11 causes the limiting plate 6 to move vertically up and down along the fixed plate 3.

[0022] The limiting plate 6 has an inclined surface at one end facing the positioning plate 7. The lower end of the inclined surface of the limiting plate 6 extends toward the fixing plate 3 with a handle 4. A T-shaped rod 13 is provided on the inclined surface of the limiting plate 6.

[0023] The positioning plate 7 has an inclined surface on the side facing the limiting plate 6 that is adapted to the limiting plate 6. A T-shaped groove 14 is provided on the inclined surface of the positioning plate 7. The groove 14 is parallel to the inclined surface of the positioning plate 7. A T-shaped rod 13 is set in the groove 14 and slides up and down in the groove 14. When the limiting plate 6 moves upward, the T-shaped rod 13 slides upward in the groove 14. The T-shaped rod 13 pulls the upper end of the positioning plate 7 toward the fixing plate 3 and pulls the upper end of the other side of the positioning plate 7 toward the fixing plate 3. The angle of the positioning plate 7 is adjusted so that the upward bending angle of the steel plate is greater than 90°, giving the steel plate a certain springback angle, which is convenient for bending the steel plate. The height of the limiting plate 6 is adjusted to adjust the angle of the positioning plate 7, which is convenient for adapting to the thickness and material of the steel plate.

[0024] The steel plate bending device for a safe described in this embodiment involves laying a steel plate flat on a support plate 1, with the end of the steel plate passing through the gap between the support plate 1 and the fixing plate 3 and lying flat above the pressure plate 10. The length of the steel plate laid above the pressure plate 10 is determined according to processing requirements. Then, the angle of the positioning plate 7 is adjusted, and the adjusting bolt 11 is rotated to allow the limiting plate 6 to move vertically up and down along the fixing plate 3. When the limiting plate 6 moves upward, the T-shaped rod 13 slides upward within the sliding groove 14, pulling the upper end of the positioning plate 7 towards the fixing plate 3, and also pulling the upper end of the other side of the positioning plate 7 towards the fixing plate 3. The angle of the positioning plate 7 is not adjusted, so that the upward bending angle of the steel plate is greater than 90°, giving the steel plate a certain springback angle, which facilitates the bending process of the steel plate. The height of the limiting plate 6 is adjusted to adjust the angle of the positioning plate 7, which is convenient to adapt to the thickness and material of the steel plate. Then, the handle 4 is pressed down to press the fixing plate 3 down onto the surface of the steel plate to fix the steel plate. The lower end face of the fixing plate 3 is provided with an anti-slip pad. The anti-slip pad of the fixing plate 3 prevents the steel plate from moving laterally when bending, increasing the stability of the steel plate. The hydraulic cylinder 9 is activated. The hydraulic cylinder 9 extends and flips the pressure plate 10 upward, thereby bending the steel plate.

Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
