Mining in stone deposits formed over hundreds of millions of years, the texture is hard and the color is bright. Because of its elegant and simple decorative effect, it has no pollution to the environment, no radiation to the human body, and is widely developed in horizontal joints and cracks. Because it is subjected to wind erosion, it forms a mushroom with a small base and a large mushroom shape on the upper part. Especially in horizontal layers, soft and hard rocks are more likely to develop into wind-eroded mushrooms. The reason for its formation is that the airflow from a certain height is less, the abrasive effect is weak, and the airflow near the ground has a large amount of sand, and the abrasive effect is strong, so the lower part is abraded more and more fine, thereby forming a mushroom stone. .
If the center of gravity of the rock at the top of the wind-eroded mushroom is inconsistent with the rock at the base, the upper rock is liable to fall. The large rock that falls down is unstable on the ground. When the wind blows, it sways with the wind, called the wind or rock. It is used for decoration and decoration of various building walls and floors of hotels, hotels, villas, gardens, etc.
The formation of many topography in arid regions, such as the formation of mushroom stones, is similar to the erosion process of flowing water. Everyone has experienced the wind and sand weather, especially in the northern regions. This phenomenon is more common. In dry areas, due to the wind and sand near the ground. More, the abrasive force is stronger, so that the rock forms a large top, and the small mushroom shape at the bottom is called "wind erosion mushroom". The airflow containing a lot of sand particles forms sand dunes when the wind speed decreases. Sand dunes can be buried in the village. She, roads, pastures, bring sand damage.
Cold extrusion is a manufacturing process in which a metal or alloy is forced through a die to create a desired shape or form. This process is typically performed at room temperature, hence the name "cold" extrusion.
A cold extrusion Hydraulic Tool is a specialized tool used to perform cold extrusion processes. It typically consists of a hydraulic press or machine that applies high pressure to force the metal or alloy through the die. The tool may also include additional components such as a die holder, die set, and ejector system.
The hydraulic system of the tool provides the necessary force to deform the metal or alloy and shape it according to the die's specifications. The pressure is applied gradually and evenly to ensure a uniform extrusion without causing any damage to the material.
Cold extrusion hydraulic tools are commonly used in various industries such as automotive, aerospace, and construction. They are used to produce complex shapes and components with high precision and strength. Some examples of products made using cold extrusion include shafts, tubes, rods, and various structural components.
Overall, cold extrusion hydraulic tools are essential in the manufacturing process of many metal and alloy products, providing a cost-effective and efficient method of producing high-quality components.
