| Push machine includes a cold push machine
The cold push machine comprises a frame, a working table, a side working table, a hydraulic press, a fuel tank, an electrical box and a control board, and a forming mold, a lifting device and a stripping device.The frame is an integral frame structure.The oil press comprises a vertical oil press arranged vertically between the column and a horizontal oil press arranged horizontally between the middle section of the column.The motor of the hydraulic press is arranged on the upper part of the machine.In the upper part of the machine, a large flow low pressure pump group is added to connect the vertical pressing oil cylinder to make the oil cylinder move quickly.The electrical box and control panel control the operation of the machine through the computer microcomputer.The utility model reduces the noise, and the arrangement of the components is more compact and reasonable.
The cold push machine itself belongs to non-standard products, so there is no specific specifications and models, we can directly customize the cold push machine according to customer requirements.We can do both the diameter of the elbow from 21mm-630mm and the thickness of the wall from 3mm-30mm.The main characteristic of the cold push machine is its low cost.All pipe fitting enterprises need to purchase cold push machine or push machine, which needs to be customized in advance. Our company needs 60 days to make the equipment, so the push machine should be prepared for reservation in advance.
The forming process of making 90 ° GB elbow is a process of using special elbow making machine, core die and heating device to make the billet on the mold move forward under the push of the machine, and be heated during the movement, expand diameter and bend forming.The deformation characteristic of hot push elbow is that the diameter of tube billet is determined according to the law that the volume of metal material is unchanged before and after plastic deformation, and the diameter of tube billet is larger than that of elbow. The billet is controlled through the core mold, and the deformation process of the billet makes the inner arc of the compressed metal flow compensated to other parts that are thinned due to diameter expansion.Thus an elbow with uniform wall thickness is obtained.Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of stainless steel elbow of some specifications.
The heating method of forming process has medium frequency or high frequency induction heating ring, flame heating and reflection heating, which heating method is used to determine the main forming product requirements and energy situation.
The above is the production method of 90 degree elbow, so it is a common pipe fitting to make 90 degree elbow in our daily life.For example, water pipes, oil pipes and other gas and liquid carrying lumens are often connected at the corner by a 90 degree elbow.The 90 degree bend is a very important connection item, because of its convenience, wide use and low price by the customer favor.A good 90 degrees national standard elbow can not only ensure that the goods transported at the corner through the safety of the leak, but also can bring a certain beauty.This is closely related to its production process.
