90 degrees gb bend manufacturer's production

90 degrees gb bend manufacturer's production process  

The forming process of making 90 degrees gb elbow is to use common elbow to make push machine, core die and heating device, so that the blank set on the mold moves forward under the push of the push machine, and is heated in the movement, expanding and bending forming process.  The deformation characteristics of hot push elbow are determined according to the law of constant volume of metal material before and after plastic deformation, the diameter of the tube is larger than the diameter of the elbow, and the blank is controlled by the core mold. The deformation process of the blank makes the metal flow compressed by the inner arc, and compensates to the other parts of the thinning due to the expansion of the diameter.  The bend with uniform wall thickness is obtained.  Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, suitable for mass production, so it has become the main forming method of carbon steel, alloy steel elbow, and also used in the forming of some specifications of stainless steel elbow.  

The heating mode of forming process has medium frequency or high frequency induction heating ring, flame heating and reflection heating, which heating mode of the main forming product requirements and energy conditions.  

The above is the production method of 90 degree elbow, so making 90 degree elbow is a common pipe fitting in our daily life.  For example, water pipes, tubing and other cavities carrying gas and liquid are often connected at the corner with a 90 degree elbow.  90 degree elbow is an extremely important connection item, because its convenience, wide use and low price are satisfied by customers.  A good 90 degree gb elbow can not only ensure the transportation of goods at the corner of the safe passage do not know to leak, but also can bring a certain beauty.  This is inseparable from its production technology.
