Stainless Steel Pipe Elbow Forming Steps And Required Equipment
What are the steps for forming stainless steel pipe elbows? Here, I will explain it to you in detail:
1. The production of Stainless Steel Weld Elbow can only be produced with the joint effect of several equipment such as presses, base molds, upper pressure molds, and filling molds. The selection of presses is that the pressure must be greater than the force of elbow deformation. The design of the upper pressure mold and the base mold is very important. Because the original technology is very advanced, the mold is also very inexpensive. The length of the mold must be greater than the length of the elbow. The processing allowance of the stainless steel elbow, the design of the filling mold is very important. Now the molds are made by CNC lathes, one thickness, one model, and one mold. The elbow is beautiful in caliber and appearance during stamping, but this problem is not easy to solve. The original stainless steel elbow is one caliber and one mold, regardless of thickness. The caliber of the elbow made in this way is very poor. The production of stainless steel elbows now is mainly for thick walls and alloys, not carbon steel.
2. The heating temperature is also an important factor in the production of elbows. The original production was based on the naked eye. When it was almost red, it was directly pulled out for processing. However, it is sometimes difficult for the naked eye to grasp the temperature. If the temperature is high, the elbow will not only fall a lot of oxide skin in the furnace, but also the thickness will decrease, resulting in a poor appearance of the elbow. In addition, the higher the temperature, the softer the elbow will be. When processing, a little pressure will deform the shape of the elbow, and it is also difficult to control. It is okay to have a slightly lower temperature, but it is a matter of increasing pressure.
3. Later stage: The elbow has passed the test, and the general shape has come out. It also needs to be plated, the mouth of the car is polished, etc. This is a delicate job, and the appearance of the elbow depends on this.
