Matters needing attention in elbow making: the diameter of tube billet must be smaller than the diameter of elbow, otherwise it will affect the wall thickness requirement of forming elbow.The deformation characteristics of the reason is due to the hot pushing elbow is according to the volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter of bend machine used by less than bend diameter, through the core module and control the deformation of the process, make the inner arc of the compressed metal flow, compensation to other parts of the thinned by expanding, resulting in wall thickness of the elbow.

Elbow push machine operation: after the tube blank is placed in the mold, the upper mold and the lower mold are combined to suppress the elbow, push down the push rod to make the mold, in order to prevent the elbow produced has the fold defect, the general pipe will inject liquid medium along the gap of the mold, that is, tap water.

The working principle of elbow pusher is as follows: press machine is used to press and form the elbow directly in the mold. Before stamping, the tube blank is placed on the lower die, the inner core and end die are loaded into the tube blank, the upper die moves downward and begins to be pressed, and the elbow is formed by the constraint of the outer die and the support of the inner die.The welding elbow rule is the method of pressing two pipe elbow half shell with mold and then welding into elbow. This method has many subsequent procedures, and the welding manufacturing technology of large thin-wall elbow is poor.        

Elbow push system of machine producing bend features: beautiful appearance, uniform wall thickness will be a lot of, meet the requirements of customers, improve the economic benefit, production method is simple in operation process, high production efficiency, low cost, high precision products, polishing, small amount of work workers labor intensity is not big, cutting loss, elbow machining allowance is small, product quality is good, but is expected to open complex shape.

The working principle of elbow machine: before the elbow machine begins to work, 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 and begins to be pressed, and the elbow is formed by the constraint of the outer die and the supporting action of the inner die.The elbow after pressing is still a semi-finished product, which needs subsequent processing. For example, push the elbow while it is hot, use the press to suppress the defect of the fold without deformation, and use the bevel machine to slope to the Angle required by the customer.Sometimes also need to execute the shot blasting process, clean up the dirt, etc., good elbow of the process delicate to very detailed.Aoguang machinery equipment Co., Ltd. is committed to providing customers with better and better services and elbow machine series products.Elbow machine is non-standard product of pipe fitting equipment, it does not have specific specifications, models and sizes, can be customized according to customer requirements, to meet the needs of customers diversity.
