The forming process of the stamping elbow is complicated, and it needs to be welded according to different materials and uses, and gradually formed under a certain pressure. The forming of the stamping elbow needs to be carried out according to a certain process, and the corresponding process is strictly followed, otherwise the quality of the stamping elbow produced will be produced. If required, a circular ring shell can be cut into 4 90 ° elbows or 6 60 ° elbows or other specifications of elbows. This process is suitable for making any elbow and elbow inner diameter ratio greater than 1.5D. Specifications Large stamping elbows are an ideal way to make large stamping elbows.
This process molding method is used in the production of different elbows and exhibits good use value in different fields, so that the process has a good value in different elbow production.
The advantages of the forming process of large punching elbows are mainly reflected in the following aspects:
(1) It is not necessary to use the tube blank as a raw material, which can save the cost of the pipe making equipment and the mold, and can obtain a stamping elbow of any large diameter and relatively thin wall thickness. The material of the stamping elbow is special, and it is not necessary to add the raw material of the tube blank, and it is easy to control during processing.
(2) The blank for processing the punching elbow is a flat plate or a developable curved surface, so the material is simple to cut, the precision is easy to ensure, the assembly and welding are convenient, the raw materials are easily controlled during processing, the operation is relatively simple, there is no complicated process, and the welding and assembly are convenient.
(3) Due to the above two reasons, the manufacturing cycle can be shortened and the production cost is greatly reduced. Because it does not require any special equipment, it is especially suitable for processing large punching elbows on site.
The material of the stamping elbow is made of carbon steel, stainless steel or alloy steel. The carbon steel stamping elbow is cheap and large in use. The elbow of alloy steel is used in a special position.
The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the steel grade of the pipe to be connected is the same.
Requirements for packaging: For small pipe fittings, such as export, you need to make a wooden box, about 1 cubic meter. The number of elbows in this box is about no more than one ton. The standard allows suits, that is, large sets, but total The weight generally cannot exceed 1 ton. For large pieces, a single package, like a 24″, must be a single package. The other is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer’s trademark. On the stamping elbow to be stamped with Packing list and other documents.
Any large-scale stamping elbow that produces a bend with a median diameter of elbow and an inner diameter of the elbow greater than 1.5D is an ideal way to make large stamping elbows. This process molding method is used in the production of different elbows and exhibits good use value in different fields, so that the process has a good value in different elbow production.
