A manual press brake, also known as a manual bending machine, is a device that utilizes manual force to bend metal pipes or other materials. This equipment is primarily used to bend straight pipes into desired angles and shapes, suitable for various applications such as small-scale production, repair work, and on-site installations. Manual press brakes have a simple structure, low cost, and are easy to operate and maintain.
Equipment functionality: Functions and application range of manual press brakes
The main function of a manual press brake is to bend pipes to specified angles using mechanical levers or screw devices. The specific functions include:
- Bending operation: Bending the pipe to the desired shape by manually applying force.
- Angle adjustment: Setting and controlling the bending angle by adjusting the mechanical device.
- Handling various materials: Capable of processing various metal materials such as steel, stainless steel, aluminum, and copper.
Manual press brakes are suitable for handling pipes of various thicknesses and diameters, but they are generally more suitable for bending thin-walled and small-diameter pipes.
Operation method: Operating steps of manual press brakes
The operation method of a manual press brake is relatively simple but requires some skill and experience. The following are the basic operating steps:
1. Preparation: Place the pipe to be bent on the bending die of the press brake and secure it.
2. Angle adjustment: Set the desired bending angle, usually achieved by adjusting the scale or angle adjustment device on the press brake.
3. Apply force: Apply force manually using the lever or screw device to initiate the bending operation.
4. Complete the bend: Continue applying force until the pipe reaches the preset bending angle, ensuring even and precise bending.
5. Remove the pipe: Release the fixation and remove the bent pipe.
Technical principle: Working principle and mechanical structure of manual press brakes
The working principle of a manual press brake is based on the lever principle or screw principle, using manual force to bend the pipe. Its mechanical structure typically includes the following parts:
- Bending die: Used to secure the pipe and provide the bending curve.
- Lever or screw device: Used to apply and control bending force, usually operated manually.
- Fixation device: Used to secure the pipe, ensuring it does not shift during the bending process.
Compared to hydraulic press brakes and CNC press brakes, manual press brakes have a simple structure, low cost, but require more manual operation. They are suitable for small-scale and simple bending tasks.
Application scenarios: Practical applications of manual press brakes
Manual press brakes have widespread applications in various industrial and manufacturing fields, including:
- Small-scale production: Suitable for small-batch and customized bending tasks, such as small factories and handcraft workshops.
- Repair work: Used for equipment and pipeline system maintenance and replacement, especially in cases where on-site operation is required.
- On-site installations: Suitable for temporary bending needs at construction sites and pipeline installation projects.
The portability and ease of operation of manual press brakes make them ideal tools for on-site operations and emergency repairs.
