Description

Technical Field

[0001] The utility model relates to the technical field of equipment for steel plate bending processing, and particularly relates to a steel plate bending device convenient for adjusting the bending angle. Background Technique

[0002] Steel plate bending is a metal processing technology. By applying pressure on a bending machine, the steel plate undergoes elastic deformation and plastic deformation, thus forming the required bending shape. This processing method does not require welding, but directly changes the form of the steel plate through mechanical force. The bending angle can be achieved by adjusting the upper and lower dies of the bending machine, and the specific operation steps of bending include marking the bending line on the designed steel plate, placing the steel plate on the lower die, applying pressure through the upper die, and finally ensuring that the bending angle meets the design requirements through a measuring tool.

[0003] In the utility model patent named "A Steel Plate Bending Device with Adjustable Bending Angle" (application number 202123418459.8), it is proposed that "the utility model relates to the technical field of steel plate bending devices, and particularly to a steel plate bending device with adjustable bending angle, including a base. A rotating groove is opened at the bottom of the base, a support frame is arranged on the top of the base, a top plate is arranged on the top of the support frame, a bending mechanism is arranged at the center of the bottom of the top plate, an adjusting mechanism is arranged in the rotating groove, and fixing mechanisms are symmetrically arranged at positions near the left and right sides of the top of the base. The two fixing mechanisms respectively include support plates. Rotating plates are respectively arranged on the surfaces of the two support plates close to the base, and rotating mechanisms are respectively arranged on the surfaces of the rotating plates far from the base; for this steel plate bending device with adjustable bending angle, by setting the fixing mechanism, the device can conveniently fix steel plates of different thicknesses, improving the work efficiency of the user. By setting the adjusting mechanism and the rotating mechanism, the device can conveniently adjust the bending angle of the steel plate according to the needs of the user, improving the work efficiency of the user." However, this utility model patent has the following problems:

[0004] 1. In this application, the threaded rod is controlled by a turntable. Such a treatment method is not good because the fixation of the turntable is not considered, so the fixation effect of the device on the steel plate cannot be guaranteed, and the best treatment effect cannot be achieved;

[0005] 2. In this application, it is not considered that the exposed threaded rod is easy to collide with the steel plate and cause damage, affecting the quality of the steel plate and the service life of the device;

[0006] 3. In this application, the structure for leveling and aligning the steel plate is not considered, resulting in inaccurate bending positions of the device and affecting the product quality. Content of the Utility Model

[0031] Working principle description:

[0032] The basic function of this device is the same as that of the utility model patent named A Steel Plate Bending Device with Adjustable Bending Angle (Application No. 202123418459.8). The device fixes the steel plate through the fixing structure 4, adjusts through the adjusting structure 3 and the rotating structure 5, and bends the steel plate through the bending member 2; It should be noted that first, the steel plate is placed on the lower clamp 7.
