| Elbow machine main production of materials and types
Elbow machine is the traditional product of Aocheng Mechanical Equipment Factory. It is mainly used to produce all kinds of elbows of 1D ~ 2.5D.
With the technical development of the elbow forming machine, the elbow machine has been improved in all directions.At present, the production of elbow machine in our factory has integrated ultra-short stress line and cone die diameter expanding technology.Digital control medium frequency induction heating technology;No back pressure, low energy consumption of hydraulic transmission technology in one.
A number of operation mechanization innovations have been realized, such as the hydraulic opening and closing of the push plate gate, the hydraulic clamping of the raw material steel pipe, etc., and combined with the new patent of our two-step advance pipe making machine innovation and expansion, we have developed new products such as the four-cylinder medium frequency elbow machine and so on.
The composition of the elbow machine equipment;Main engine, hydraulic pump station, operation table, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjusting frame, reactor
The raw material of the elbow push machine is seamless steel pipe, welded steel pipe and rolled steel pipe.
The product specification range of the elbow is: diameter 21-1620mm, wall thickness 3-120mm, the length of the material steel pipe 3-24m, elbow pushing machine mold (core), heating coil, ordered by the user alone.The elbow pushing machine is made by the user alone.Elbow push machine low price, quality assurance, high production efficiency.We can debug and customize according to customer's requirements.
Elbow push machine is divided into hot push and cold push
Hot push elbow push-making machine is to put the pre-cut pipe section on the horn core head, and heat it to the austenite area. Through the thrust exerted at the back of the pipe section, the pipe section receives eccentric diameter expansion and bending deformation, and is processed into an elbow with enlarged diameter and unchanged wall thickness.When the flame is heated, the temperature of the tube billet in the setting section is also very high, generally above 70° C, so that the setting section needs to be longer to prevent other deformation of the elbow. For the mandrel itself, in the bending process, the temperature of each section of the mandrel in the heating furnace is very high, and the anti-deformation gravity of the tube billet acts on the mandrel.The mandrel may be straightened or broken when working for a long time under high temperature stress, so the medium frequency induction heating is used.Elbow push machine itself belongs to non-standard products, so there is no specific specifications and models, we can directly customize according to customer requirements
Elbow diameter from 21mm to 1620mm, wall thickness from 3mm to 120mm we can do
Elbow push machine is mainly used for carbon steel and alloy steel elbow forming, if the product you need is stainless steel elbow, please choose cold push elbow machine
Stamping forming: Stamping forming elbow is the earliest forming process used in mass production of seamless elbow, which has been replaced by hot pushing or other forming processes in the production of elbow in common specifications, but in some specifications of elbow due to less production, too thick or too thin wall thickness.The product is still in use when there are special requirements.The stamping of the elbow is made of tube billet equal to the outside diameter of the elbow, which is directly pressed into shape in the die by a press.Before stamping, the tube billet is placed on the lower die, the inner core and end die are loaded into the tube billet, the upper die moves downward to suppress, and the elbow is formed through the constraint of the outer die and the supporting effect of the inner die.
Compared with the hot push process, the appearance quality of the elbow produced by the press elbow push-making machine is inferior to the former;The outer arc of the stamping elbow is in a stretching state when forming, and there is no excess metal in other parts to compensate, so the wall thickness at the outer arc is about 10% thinner.However, because it is suitable for single production and low cost, stamping elbow technology is mostly used in the manufacture of small batch and thick wall elbow.
Stamping elbow is divided into cold stamping and hot stamping, usually according to the material properties and equipment capacity to choose cold stamping or hot stamping.
