Stainless Steel Checkweigher/Check Weigher with High Accuracy

Stamping welding elbow, it is the same material with the tube sheet metal stamping die with a half block ring bend, and then the two half ring elbow for welding. Because of various pipe welding standards are different, usually by the group on the fixed semi-finished products of the factory, on-site construction according to the pipe weld level of welding, therefore, also known as the two halves of the welding elbow.Pipe installation of a commonly used in connection with the pipe, connecting the two nominal diameter of the same or different tubes, so that the pipe to make a certain angle turn.

Advantage

The stamping production efficiency is high, and the operation is convenient, easy to realize mechanization and automation, this is because the stamping die and stamping equipment is to rely on to complete the processing, ordinary press trips as per minute

Up to several tens of times, high-speed pressure to hundreds of times per minute or more, and every time the punch stroke may get a punch.

The stamping generally without cutting scrap generated, material consumption is less, and does not need to other heating equipment, so it is a kind of material saving, energy saving and processing, stamping parts of the cost is low.

The stamping process the size range is larger, more complex shape parts, such as a small clock stopwatch to auto longeron, covering parts, stamping cold material deformation hardening effect and punching strength and stiffness are higher.

The stamping die due to ensure the stamping part dimension and shape precision, and generally does not destroy the stamping parts of the surface quality, and die life is generally longer, so stamping quality stability and interchangeability good, has the characteristic of "identical".

The forming process of stamping elbow is complicated, and it needs to be welded according to different materials and uses, and is gradually formed under certain pressure. Stamping elbow molding need according to a certain process, strictly comply with the corresponding process, otherwise the production of stamping elbow will produce quality problems. According to the need, a circular ring shell can be cut into 90 6 degree elbow or 60 elbow or other specifications of the elbow, the process is applied to the

Any specification of large scale, with the diameter of the elbow and the diameter of the elbow is larger than that of the 1.5D, is an ideal method for the manufacture of large push bends.

This process molding method used in the production of different bends, in different areas to show good use value, so that the process in the production of different bends with good value reflected.

The advantages of the forming process of large stamping elbow are mainly shown in the following aspects:

Stamping elbow

One need not tube for raw materials, save the tube making equipment and the mold expense and can get arbitrary large diameter and wall thickness relatively thin push of elbow. The raw material of the punching elbow is special, and the raw material of the pipe blank is not needed to be added.

The stamping elbow blank is flat or developable surface, and thus a simple material, to ensure accuracy. Assembly welding is convenient, in the processing of easy control of raw materials, simple operation, no complicated process and welding and assembly is convenient.

Because of the above two reasons, can shorten the manufacturing cycle and the production cost is greatly reduced. Because no special equipment is needed, especially suitable for the field processing of large stamping elbow.

Material

Stamping elbow material is carbon steel, stainless steel, alloy steel and other materials. Carbon steel stamping elbow is cheap, the use of large. The alloy steel elbow is used in a special position on the.

Stainless steel stamping elbow is different from carbon steel elbow is the main material of different materials, the chemical composition will keep the elbow for a long time will not rust, is not easy to be corroded.

Stainless steel, stainless steel, corrosion resistance as the main characteristics, and the chromium content of at least 10.5%, the maximum carbon content of not more than 1.2% of the steel.

Stamping elbow thickness standard

After the arrival of the scene of the stamping elbow, the thickness of the stamping elbow while improving the process, the average thickness of the thick wall of the stamping elbow to seriously exceed the standard, need to be calculated according to the actual measurement.

In the process of calculation conducted among, wall thickness of the general accounting process, general pipeline equipment, general interface thrust and the thrust is qualified of, of course, docking pipeline whether or not to set up a reasonable. For pipeline calculation of punching elbow should stress strengthen coefficient and flexible coefficient, of course, re accounting check when, the consistency of calculating stress strengthen coefficient of pipe wall thickness, this by the weight of the elbow were reduced wall thickness is stamping elbow along the center line were carried out straight, ensure stamping elbow straight weight and stamping elbow weight, stamping elbow for stamping elbow weight conversion of wall thickness.
