如何为曼哈特（广东）数控有限公司制作折弯机

Making a bending machine requires some basic tools and materials, including steel plates, steel pipes, screws and nuts, manual jacks, hand saws or electric saws, hand drills, hand welding machines, etc. Here is a simple production step:
1. Cut two steel pipes according to the required size as the two pillars of the support frame. Generally speaking, these two steel pipes should be slightly longer than the metal sheet you need to bend.

2. Fix two steel pipes on the steel plate as the foundation for the bending area. Ensure that this foundation is solid and not easily movable.
3. Use a hand electric drill to drill holes on two steel pipes and fix them on the steel plate. These holes should match the screws and nuts you have prepared.
4. Install the manual jack on the top of the support frame. Ensure that the top of the jack is aligned with the bending area of the metal sheet.
5. Use a manual welding machine to connect the steel pipe and jack together. Ensure that the welding is firm and not easily loosened.
6. Install some clips on the bending area of the steel plate to help you firmly place the metal plate there.
Now, you can start using your homemade small bending machine. Place the metal sheet that needs to be bent on the support frame, adjust the height of the jack, and then fix the metal sheet on the bending area with a clip. Then, slowly turn the handle of the jack until the metal sheet folds into the desired shape.
By following the above steps, you should be able to create a simple and practical bending machine for bending small metal sheets. Of course, this process may require some hands-on ability and skills. If more complex bending machines are needed or if problems arise during the production process, it is recommended to seek the help of professionals.
