Description

Technical Field

[0001] The utility model relates to the technical field of metal bending, in particular to a metal plate bending machine which is convenient to operate. Background Art

[0002] Metal bending is a processing method in which a metal plate is placed on a mold and bent under the action of force. During the bending process, the metal plate first undergoes elastic deformation and then enters the plastic deformation stage. In the initial stage of plastic bending, the sheet metal is freely bent. Metal bending has many advantages, such as reducing labor costs, improving production flexibility, and improving production efficiency.

[0003] During the metal bending process, corresponding upper and lower dies are generally used for right-angle bending or rounded-corner bending according to the bending requirements of the metal plate. However, common bending machines can only complete single right-angle bending or rounded-corner bending. When it is necessary to change the bending effect, the operator needs to replace the upper and lower dies of the bending machine in sequence, which takes a long time and is not easy to operate. Therefore, a metal plate bending machine that is convenient to operate is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-speed pretreatment water treatment device to solve the problems raised in the above background art: during the metal bending process, corresponding upper and lower dies are generally used for right-angle bending or rounded-corner bending according to the bending requirements of the metal plate. However, common bending machines can only complete single right-angle bending or rounded-corner bending. When it is necessary to change the bending effect, the operator needs to replace the upper and lower dies of the bending machine in sequence, which takes a long time and is not easy to operate.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a metal plate bending machine that is convenient to operate, including an installation base plate. Between the two sides of the upper surface of the installation base plate, an installation top plate is fixedly connected through four lifting guide rods. At the center of the upper surface of the installation top plate, an electric hydraulic cylinder is fixedly installed. The output end of the electric hydraulic cylinder is fixedly connected with a bending component. The bending component is inserted and connected with the lifting guide rods in the opposite position. On one side of the upper surface of the installation base plate, a first material placing component is connected. On the other side of the upper surface of the installation base plate, a second material placing component is connected. Both the first material placing component and the second material placing component are located below the bending component.

[0006] Preferably, the bending component includes a propulsion connecting plate. The upper surface of the propulsion connecting plate is fixedly connected with the output end of the electric hydraulic cylinder. The lower surface of the propulsion connecting plate is connected with two propulsion cross plates through a plurality of positioning bolts. The propulsion cross plate close to the first material placing component is fixedly connected with a right-angle bending plate, and the propulsion cross plate close to the second material placing component is fixedly connected with a rounded-corner bending plate.

[0007] Preferably, the first material placement component includes two trapezoidal material placement plates, and first positioning blocks are fixedly connected to both ends of the two trapezoidal material placement plates.

[0008] Preferably, each first positioning block is threadedly connected to the mounting substrate through a first fastening bolt, and the right-angle bending plate is located between the two trapezoidal material placement plates.

[0009] Preferably, the second material placement component includes two cylindrical material placement plates, and the rounded-corner bending plate is located between the two cylindrical material placement plates.

There is no need to replace the upper and lower dies of the bending machine, avoiding the cumbersome process of replacing the upper and lower dies, and the operation is more convenient. It solves the problem that in the process of metal bending, generally corresponding upper and lower dies are used for right-angle bending or rounded-corner bending according to the bending requirements of the metal plate, while the common bending machine can only complete single right-angle bending or rounded-corner bending. When it is necessary to change the bending effect, the operator needs to replace the upper and lower dies of the bending machine in sequence, which takes a long time and is not easy to operate.

[0013] (2) This device can push the bending component downward through the provided electric hydraulic cylinder.
