| The overall introduction of elbow machine and push machine
Application: seamless steel pipe, straight seam welded steel pipe and spiral welded steel pipe.
1, the elbow specification range is: outside diameter: Φ25mm ~ Φ1420mm;Wall thickness: 5mm ~ 120mm;(Design and manufacture the equipment in stages)
2. Angle: 22.5°, 45°, 90°, 135° and any Angle required by users;
3. The radius of curvature of the elbow is 1D ~ 2.5D
4, according to the need to push a variety of curvature radius of the bending steel pipe, also known as the unequal diameter bend pipe.
Unit 2, elbow push system structure: equipment frame rails and the main cylinder and the plate, activities before pushing plate, plate, feeding device, intermediate frequency coil adjustment device (intermediate frequency heating coil, bend mold, mold rod), intermediate frequency power supply heating equipment, electrical control system, hydraulic control system, work station (touch screen), cooling water circulation system, etc.
3. Auxiliary equipment of elbow pushing machine: hydraulic press (elbow shaping and whole mouth use), elbow shaping mold, elbow whole mouth mold, elbow beveling machine, steel pipe sawing machine, high-temperature lubricant (graphite) spraying equipment on the inner wall of steel pipe.
The medium frequency push-making machine is the traditional product of the pipeline equipment factory. It is mainly used for the production of various diameter and wall thickness elbow pipe fittings with curvature radius of 1 ~ 2.5D.With the development of deep processing technology of steel pipe, the product has been improved in all directions.The equipment has integrated ultra-short stress line cone die diameter expansion, digital control medium frequency induction heating, the application of no back pressure energy consumption hydraulic transmission and other technologies.All gate opening and closing adopt solenoid reversing valve, realize the double control of gate site and operation table, at the same time increase the raw material steel pipe hydraulic clamp and other automatic operation technologies, and combined with the factory's hot pipe expanding machine technology, the corresponding production of four cylinder extra-large and extra-thick elbow pipe pushing machine and other hydraulic pushing equipment.After the equipment is equipped with the intelligent thermostatic control system of medium frequency power supply heating, it can realize the operation and control of multiple devices by one person, energy saving and environmental protection, safe operation and other functions.
The advantages and production process of hot push elbow machine
Hot push elbow technology that is the advantage of medium frequency heating elbow machine: hot push elbow wall thickness unchanged.
According to the expansion and flow laws of metal materials, the translation of the bending neutral layer to the outer arc and the non-plastic deformation of the outer arc of the elbow are realized by the theoretical calculation and the medium frequency induction heating pushing process, so that the wall thickness of the elbow is not thinned during the bending process.Namely, after bending the elbow, the wall thickness of the outer belly and the inner belly is uniform, which avoids the uneven wall thickness phenomenon of the inner side thickening and the outer side thinning during the deformation of the traditional bending process.Intermediate frequency bend machine belong to the non-standard products, there is no specific limit specifications, can according to customers' special requirements directly, Mr Cheng machinery co., LTD. Not only the production of bend machine, intermediate frequency bend machine drive system, and intermediate frequency pipe bending machine, cold extrusion machine, cold drawing tee thermoforming pipe-expanding machine and other mechanical equipment, equipment can meet the domestic and foreign market demand.
