The appearance of the national standard elbow is beautiful by using the push machine
The forming process of making 90 ° GB elbow is a process of making a push-making machine, a core die and a heating device with commonly used elbow, so that the billet on the mold moves forward under the push of the push-making machine, and is heated during the movement, expanding the diameter and bending.The deformation characteristic of hot push elbow is that the diameter of tube billet is determined according to the law that the volume of metal material is unchanged before and after plastic deformation, and the diameter of tube billet is larger than that of elbow. The billet is controlled through the core mold, and the deformation process of the billet makes the inner arc of the compressed metal flow compensated to other parts that are thinned due to diameter expansion.Thus an elbow with uniform wall thickness is obtained.Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of stainless steel elbow of some specifications.
The heating method of forming process has medium frequency or high frequency induction heating ring, flame heating and reflection heating, which heating method is used to determine the main forming product requirements and energy situation.
The above is the production method of 90 degree elbow, so it is a common pipe fitting to make 90 degree elbow in our daily life.For example, water pipes, oil pipes and other gas and liquid carrying lumens are often connected at the corner by a 90 degree elbow.The 90 degree bend is a very important connection item, because of its convenience, wide use and low price by the customer favor.A good 90 degrees national standard elbow can ensure that the goods transported at the corner of the stable through the leak, but also can bring a certain beauty.This is closely related to its production process.
What is the difference between 1.5D elbow and 1D elbow
1.5D elbow refers to the bending radius of the elbow is 1.5D, which is 1.5 times the diameter of the bending object required.In piping systems, an elbow is a pipe fitting that changes the direction of the pipe.The elbow is divided into angles, and the elbow is the pipe fitting to cha
