The mold on the stainless steel pipe welding machine is one of the key equipment used to produce various types of welded pipes. The following is a comprehensive knowledge of welded pipe molds:
1. The purpose of welded pipe molds:
Welded pipe molds are mainly used to produce stainless steel profiles, copper, aluminum, iron profiles and high-frequency welded pipes. Its quality directly affects the quality and performance of the final product.
2. Working principle of welded pipe molds:
1. Forming stage: The steel strip is fed into the forming mold and rolled into a tube.
2. Welding stage: Welding is performed in the welding area, and argon arc welding or high-frequency welding can be used.
3. Shaping stage: The pipe is pressed into a standard size through a shaping mold.
4. Cutting stage: The pipe is coiled or cut to size to complete the product production.
3. Types of welded pipe molds:
1. Round pipe mold
2. Square pipe mold
3. Plum blossom pipe mold
4. Round head flat pipe mold
5. Elliptical pipe mold
6. Fan-shaped pipe mold
7. Octagonal pipe mold
8. Customized special-shaped stainless steel profile mold
4. Production process of welded pipe molds:
1. Cutting
2. Rough processing
3. Heat treatment (high temperature quenching and high temperature tempering)
4. Finishing
5. Nitriding
6. Finished product processing
5. Classification of welded pipe molds:
1. Horizontal mold: mold with shaft hole and keyway
2. Vertical mold: mold with bearing
6. Pipe specifications:
1. Round pipe: Φ5~Φ325, material is Cr12MoV/SKD11, hardness range is 61~65HRC.
2. Square tube: F10*10~F300*300, the material and hardness range are the same as those of round tubes.
3. Rectangular tube: F10*20~F120*60, the material and hardness range are the same as those of round tubes.
VII. Common specifications of welded pipe molds:
Common specifications include 40 machines, 50 machines and 60 machines, and specific specifications can be customized according to production needs.
VIII. Mold quality judgment criteria:
1. Use high-quality mold steel Cr12MoV/SKD11.
2. Adopt reasonable molding design principles.
3. After high-precision CNC machining and vacuum gas quenching and hardening treatment, the overall hardness of the mold reaches about HRC65°.
4. The pipe making effect is smooth and stable, the pipe making efficiency is high, and no strain or nail marks will be produced.
The above is the comprehensive knowledge of welded pipe molds, I hope it will be helpful to you!
