| The form and working principle of cold push elbow machine
Cold push elbow machine is used for the formation of elbow, the main power is hydraulic cylinder, there are two forms, ball type and mandrel type.
Working principle of cold push elbow machine: under normal temperature, the special hydraulic press is used to press the pipe blank into the mold of bending cavity, and the method of pushing and forming pipe elbow is divided into the production method of elbow with and without core according to the forming process.
Steel tube bending, under the condition of without mandrel, the cross-sectional or elliptical deformation can occur in a large or small, pipe deformation zone, the lateral materials by tangential tensile and elongation, the inside of the material by tangential compression and shortening, outside wall thinning, rupture, inside wall thickening, wrinkling and cross section distortion, and the springback after unloading and its control, pipe bending forming is difficult to effectively solve the technical problems.
Cold push elbow machine is mainly used for stainless steel elbow forming, if the product you need is carbon steel or alloy steel elbow, it is recommended that you choose medium frequency elbow machine.
Stainless steel elbow machine is the main equipment to produce stainless steel pipe fittings
Stainless steel elbow machine is mainly suitable for stainless steel elbow pipe fittings, push into 90 - degree bend of special equipment, forming method for side ejector push straight in the main die bending on the mandrel, and equipped with automatic peeling device will bend peeling off from the mandrel, electrical system adopts PLC control, hydraulic system adopts cartridge valve, convenient maintenance, simple operation, high production efficiency.
The overall structure of stainless steel elbow machine: host, hydraulic station, electric control cabinet, limit device four parts.
The elbow released by the stainless steel elbow machine is relatively uniform. The thickness of the outer wall of the elbow is the same as that of the pipe billet. The thinning of the inner wall is the largest, and the middle is gradually transferred.
Elbow determines the shape of elbow when use the lateral metal than the inside of the metal to bear a greater impact, and the core rod extrusion bending method made of stainless steel elbow mechanism elbow at its point of deformation happens to conform to the terms of the use of the elbow, the mechanical device has simple structure, low cost, unloading, convenient and simple clamping, high production efficiency, product quality meet the production requirements.Our company not only produces stainless steel elbow machine, but also produces tee machine, press machine, pipe expanding machine, beveling machine, pipe bending machine, and mould for the above pipe fittings and equipment.Welcome new and old users call.
