| The process of pushing the machine to produce the elbow
Push system machine push system process is a process of expanding with bending, behind the support, the feeding pipe segment into the mandrel, behind a arch frame will be fixed mandrel, there is a car in the middle, some car through hydraulic transmission, some through mechanical transmission that is, screw transmission, and then forward the car.The trolley pushes the pipe forward along the new version, and the mandlet goes forward. There is an induction ring on the outside of the new version. Heate the pipe, and then the trolley pushes the pipe down to finish the processing of one.A die is actually a press and requires a set of dies.Two semicircular arcs, one above and one below.After the outside diameter reached the size requirements of the finished product, the wall thickness is controlled by the wall thickness of the incoming material.The wall thickness tolerances of the elbow and pipe are the same and should not change normally during the pushing process.
When the production of elbow to choose the specified steel pipe.Through theoretical calculation, the general diameter expansion rate is between 33%-35%, and pushed back.Short radius 219mm general diameter expansion rate is 50% after the selection of raw materials, according to the specifications of the elbow, considering the radius of curvature such as: 90 degrees of elbow, through the curvature can be calculated under the long material processing 90 degrees of elbow, can be calculated through theoretical calculation, and then the length of the length as the ruler to cut off, and finally the material is hot push system.Push machine you may have seen, the actual horizontal simple, it is a horn - shaped core head or mandrel.
Elbow machine is the main equipment for the production of elbow, with a history of nearly ten years.With the development of deep processing technology in our factory, the product has been improved in all directions.At present, elbow machine manufacturers produce elbow machine is heating technology.Elbow products for the production of raw steel pipe: seamless steel pipe, welded steel pipe and coil steel pipe.The equipment can produce elbow product specifications range: outer diameter wall thickness 5-120,1 inch -60 inch, Angle: 22.5 degrees 45 degrees 90 degrees 135 degrees, etc. Can be customized according to customer requirements.
The elbow machine has realized the hydraulic opening and closing of the push plate gate, the hydraulic clamping of the raw material steel pipe and other operating machinery, and combined with the new patent of the innovation and expansion of the company's two-step push machine, developed the four-cylinder elbow push machine and other products.
The outer diameter and wall thickness of the elbow are produced according to the needs of users. The power of medium frequency heating power supply, thrust stroke of the cylinder and the number of cylinders are configured.The elbow machine is composed of the following components: the main machine of the elbow pushing machine, the hydraulic pump station, the motor control cabinet, the intermediate frequency power supply, the compensation electric fusion device, the cable, the intermediate frequency coil adjusting frame, the reactor.
