Stainless steel elbow processing process
The use and processing of stainless steel elbows need to be carried out according to special processes. The selected welding process is used for welding to produce better quality stainless steel elbow products and provide users with better satisfaction and services. Steel Non-ferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, lead, zinc, brass, bronze and bearing alloys.
In addition, chromium, nickel, manganese, molybdenum, cobalt steel, vanadium, tungsten, titanium, etc. are also used in industry. These metals are mainly used for alloy additions. Due to the properties of the metal, tungsten, steel, titanium, molybdenum, etc. are mostly used in the production of Carbide for cutting tools.
Little knowledge in the production process of stainless steel elbow
The heating temperature is also a key factor in the production of stainless steel elbows. The original production also relied on the human eye to see when it is almost red, and then pull it up and press it. However, the human eye is sometimes not very good at controlling the temperature.
If the temperature is high, the elbow will not only shed a lot of oxide scale in the furnace, but also the thickness will be reduced, causing the appearance of the elbow to be poor. Secondly, the higher the temperature, the softer the elbow will be and there will be a little pressure when processing. Even the shape of the deformed elbow is not easy to control. It's okay if the temperature is a little lower, it's just a matter of increasing the pressure.
The production of stainless steel elbows can also be produced with the joint action of several equipments such as presses, base molds, upper pressure molds, and filling molds. The selection of the press is that the pressure is much greater than the force of the elbow deformation. The upper pressure mold and Base mold design
In view of the original process, the mold is also very poor. The length of the mold is much longer than the length of the elbow. The machining allowance of the stainless steel elbow is very important. The design of the filling mold is very important. Nowadays, the molds are made by CNC lathes, one thickness, one model, one mold. , when the elbow is stamped, the caliber and appearance are beautiful
But it turns out that this problem is not easy to solve. The original stainless steel elbow only has one caliber and one mold. The caliber of the elbow made without distinguishing the thickness is very bad. The current stainless steel elbow production is only for thick wall and alloy. For the sake of weight, it is not made of carbon steel.
Stainless steel elbow production process
If you want to make a long radius elbow, you need to choose a specific specification and specify the pipe material. The diameter expansion rate, after theoretical analysis, is usually between 33% and 35%, which can be calculated backwards. The general diameter expansion rate for a short radius of 219mm is 50%. After selecting the raw materials, cut the materials according to the elbow specifications, and then consider the radius of curvature.
For example, for a 90° elbow, the curvature should be used to calculate the length of material that can be used to produce a 90° elbow. It can be calculated through theoretical analysis, and the length is used as a fixed length for disconnection. Then the material is heated and pushed. You may have seen the push machine, but it is actually very easy.
