Push the machine

The working principle of the cold-push elbow pushing machine: put the tube billet into the outer die. After the upper and lower dies are closed, under the axial push of the push rod, the tube billet moves along the clearance reserved by the inner and outer die to complete the forming process.In order to prevent the bending phenomenon after forming, the gap between the inner and outer die is filled with water and liquid.The elbow probably needs to be finished after it is formed. Shot peening treatment is to remove the iron scale on the inside and outside surface of the elbow. The second is to carry out groove treatment to make it easy to weld and then carry out sand blasting.The sequence of sand blasting and groove is decided according to customer demand. The brightness of sand blasting and groove is higher, and the brightness is lower on the contrary.Then make steel word, packaging and other procedures can be put into storage and factory.Cold pushing elbow pushing machine has the following advantages that other pushing machines do not have:

Cold push elbow machine has the following advantages: cold extrusion process pushed out of the elbow shape elegant, size error rate is small, so stainless steel elbow manufacturing more use cold push elbow push machine this automatic process technology products.Aocheng mechanical equipment Co., LTD. Not only sells and custom-made elbow and elbow production of mechanical equipment, mainly cold push elbow machine, medium frequency induction heating elbow machine (the main power for hydraulic cylinder).Customers can choose according to their own needs.If you need stainless steel elbow, please select cold push elbow press.If required for carbon steel or alloy steel elbow, it is an intermediate frequency push machine elbow.We sell to domestic and foreign customers with high quality products, relatively high cost performance reputation, buyback customers have trust in our company and product quality, welcome new and old customers to order a series of pipe fittings and mechanical equipment of our company.Cold - push elbow machine low cost, high cost performance.

Cold push elbow machine

Cold push elbow machine in the forming of the outer arc in the state of tension, no other parts of the excess metal compensation, so the wall thickness of the outer arc about 10% thin.However, because it is suitable for single piece production and low cost, cold push elbow machine process is mostly used for small batch, thick wall elbow manufacturing.

The working principle of the cold push elbow machine is: the specific working process of the cold push elbow machine is to use a special elbow forming machine to put the tube blank into the outer die. After the upper and lower dies are closed, under the push of the push rod, the tube blank moves along the clearance reserved by the inner die and the outer die to complete the forming process.The elbow made by the cold extrusion process of internal and external die is beautiful in appearance, uniform in wall thickness and small in size deviation, so the stainless steel elbow, especially the stainless steel elbow formed by thin wall, is mostly made by this process.The precision of the inner and outer mold used in this process is high.The wall thickness deviation of the tube billet is also demanding.

Cold push elbow machine is usually used in petroleum, chemical industry, electric power, Marine, military industry, aerospace, high-speed rail and other industries engineering pipe elbow manufacturing.

The cold push elbow machine is to make the elbow stretch and bend into shape after the steel tube is cold extruded.In order to prevent the defects such as creasing or reducing wall thickness during the clearance movement of the pipe billet during the cold extrusion process, two points should be paid attention to: first, the length of the blanking steel pipe material should be greater than the length of the customized elbow.Second, add tap water in the interstitial motion process to prevent bending.
