Outer water blocking punching machine

The external water blocking punching machine is a commonly used mechanical equipment in the punching process, mainly used for cutting metal materials, with efficient and accurate cutting capabilities. It is a mechanical device that uses water pressure to spray water onto the workpiece for cutting, hence it is also known as a water cutting machine.

The working principle of the external water blocking punching cutting machine is to send water into the hydraulic system through a water pump, forming a high-pressure water flow, which is then sent to the cutting head and sprayed out through the nozzle of the cutting head. The cutting head is usually referred to as a "syringe" by physicists. The high-speed jet of water generates a huge impact force and high thermal energy when in contact with the workpiece, thereby cutting the workpiece into the desired shape.

The high-pressure water flow of the external water blocking punching machine can cut various materials, including metal, stone, ceramics, plastics, etc. Compared to traditional mechanical cutting methods, the outer water blocking punching machine has the following advantages:

1. High precision cutting: The water cutting machine can perform micro cutting under precise control, resulting in a smooth surface of the workpiece and smooth cutting lines. In cutting workpieces with high requirements for size, it has obvious advantages.

2. No thermal deformation: Due to the use of water flow for cutting, high temperatures will not be generated during the cutting process, greatly reducing the heat affected area of heat conduction to the workpiece. This can avoid deformation problems caused by high temperatures.

3. No cutting stress: During water cutting, there is no cutting stress, so it does not affect the material itself, reducing stress effects such as stretching and squeezing caused by cutting force, and maintaining the original properties of the material.

4. Multifunctional cutting: The external water blocking punching machine can not only cut various materials, but also perform complex shape cutting. By controlling the spray angle and speed of water flow, a water cutting machine can cut workpieces of different shapes such as flat, three-dimensional, and curved surfaces.

5. Environmental Protection and Energy Conservation: Compared to traditional cutting methods, the external water blocking punching machine is more environmentally friendly and energy-saving. Using high-pressure water flow for cutting does not require the use of chemical solvents and cutting fluids, and the energy consumption is relatively low.

Although the external water blocking punching machine has various advantages in the cutting process, there are also some limitations. Firstly, the cutting speed is relatively slow, especially when cutting materials with larger thicknesses, the cutting speed of the water cutting machine will further decrease.

In addition, water cutting machines also require higher cutting costs. Water pumps, high-pressure equipment, cutting heads, and other equipment are relatively expensive, and maintenance costs are also high. At the same time, after cutting for a period of time, due to severe wear and tear on the cutting head, it is necessary to replace the cutting head, further increasing the cutting cost.

Another issue is the environmental pollution caused by wastewater treatment. The wastewater generated during the high-pressure water flow cutting process needs to be treated with special equipment to ensure that it does not cause pollution to the environment.

In summary, the outer water blocking punching cutting machine is an efficient and accurate cutting equipment widely used in various fields, especially in areas with high requirements for cutting accuracy. With the progress of technology and continuous improvement of equipment technology, it is believed that the external water blocking punching machine will have a broader application field in the future. Meanwhile, for the performance improvement of water cutting machines
