Hot pushing elbow machine molding technology
Push heat bend molding process is to accept special machine, core die elbow push system and heating device, make on the mould of billet in pushing forward activity, under the impetus of the machine is heated in the activity, hole diameter and bending forming process.Credentials of metal material is hot push bend deformation characteristics before and after plastic deformation volume stability of discipline determine the pipe diameter, the acceptance of the pipe diameter less than bend diameter, through the core module and control the deformation of the course, make the inner arc of the compressed metal activity, compensation to other parts of the thinned by expanding, thickness and the symmetry of the elbow.
Hot pushing elbow machine molding process with shape regards, symmetrical for homework, wall thickness is suitable for the characteristics of mass production, and thus become an important forming method of carbon steel, alloy steel elbow, and also applied in some of the specifications of the stainless steel elbow forming.Forming process of the heating method is intermediate frequency or high frequency heating (heating can be multiple times or lap), flame heating and reverberatory furnace heating, accept all kinds of heating methods depending on forming the product requirements and energy environment decision. |
