Technology of stamping elbow production

Stamping elbow is the earliest production process of elbow. At present, this process only aims at the production of elbow with large thickness, high pressure, hard material and limited drawing.Here I would like to introduce to you the technical essentials and matters needing attention of stamping elbow production.

Stamping elbow production has the press, the base mould, embossed on the mould, and filling mold equipment can produce, under the function of the choice of the press must be pressure is greater than the strength of the bend deformation, the pressure of the mold base and mold design, due to the original after the process is, it was not an precision mold, the mold length must be greater than the length of the bend guarantee the machining allowance of stamping elbow, filling mould design is more important now are made of CNC lathe mold a thickness of a type a mold guarantee bend when punching diameter and appearance is beautiful but it is not good to solve the problem,Original stamping elbow is a diameter a mold, regardless of the thickness of that promise to bend diameter is very bad, now of the stamping elbow alloy production is only in view of the thick wall and not to give priority to dozen of the carbon steel.

Heating temperature is stamping elbow an important factor of production, the original production is visible to watch almost burned directly pull out, but sometimes the human eye is very bad to grasp the temperature, high temperature, especially if the elbow is not only in the furnace will drop a lot of leather and the thickness of the oxide will lead to the elbow outlook is bad also is the lower temperature, the higher the elbow more soft processing time able to bend a little pressure on deformation control are in bad shape.A slightly lower temperature is nothing but a higher pressure.

It is the later shaping: after pressing, the general appearance of the stamping elbow has come out, and it still needs to be finished, such as disc mouth, car mouth grinding, etc. This is a fine work, the appearance of the stamping elbow depends on this.
