What are the requirements for raw materials for cold heading machines?

1. The chemical composition and mechanical properties of the raw materials for cold heading of the cold heading machine should meet the relevant standards of the multi-station automatic cold heading machine. To 2. The raw materials must be spheroidized and annealed, and the metallographic structure of the material is spherical pearlite grade 4-6. To 3. The hardness of raw materials, in order to reduce the tendency of material cracking as much as possible, and to improve the service life of the mold, it is also required that the cold drawn material have the lowest possible hardness to improve plasticity. Yupu cold heading machining indicates that the hardness of raw materials is generally required to be HB110~170 (HRB62-88). To 4. The full-inch accuracy of cold drawn materials should generally be determined according to the specific requirements of the product and the process conditions. Generally speaking, the multi-station cold heading machine has lower requirements for reduced diameter and forced dimensional accuracy. To 5. The surface quality of cold drawn materials requires that the lubricating film is dull and dark, and the surface must not have defects such as scratches, folds, cracks, napping, rust, oxide skin, and pits and pits. To 6. It is required that the total thickness of the decarburized layer in the radial direction of the cold drawn material does not exceed 1-1.5% of the diameter of the raw material (the specific situation depends on the requirements of each manufacturer). To 7. In order to ensure the cutting quality during cold forming, the cold drawn material is required to have a harder surface and a softer core. To 8. Cold-drawn materials should be subjected to a cold upsetting test. Yupu cold-heading machine processing means that the cold-heading machine also requires the material to be less sensitive to cold work hardening, the better, in order to reduce the deformation resistance due to cold work hardening during the deformation process Increase.

A brief introduction to butt welding elbow

The shape of the elbow is the same as the normal seamless elbow or straight seam elbow. It is also divided into 90° butt welding elbow, 45° butt welding elbow, 180° butt welding elbow, etc., this kind of butt welding elbow The cost of the head is low, and it is suitable for large-diameter elbows. For example, the size of 600 or more can be butt-welded. And there is a special implementation standard for butt-welded elbows that is the national standard 13401-97. This standard gives The specific dimensions of the butt-welded elbow and its welding method are presented, which is a useful document.

Stainless steel flange model specifications and usage matters

There are one-piece, two-piece, three-piece, etc. stainless steel flanges. At present, three-piece stainless steel flanged ball valves are more commonly used. The size ranges from 0.5 to 2 inches. The valve body is processed with an ISO 5211 standard Perform structural installation according to the mouth. The valve is a full-bore ball valve, and the handle can be locked at the switch position. The pressure end of the stainless steel flanged ball valve has high temperature resistant and easy to connect FKM sealing parts. The good stainless steel ball and stem allow it to be widely used in industrial engineering.
