Abstract

The invention discloses a forming method of a pure nickel tee. The forming method is characterized by comprising the steps that a, a raw material is selected and used, a tubular blank with a length greater than the depth of an upsetting hole and the diameter same as the upsetting hole is used as the raw material; b, solid particles that can deform with pressure are injected into the tubular blankin the step a; c, the tubular blank injected with river sand in the step b is put into a forming mold for upsetting, that is, the diameter of the point, being subjected to upsetting, of the tubular blank is increased, so that the cross section of the tubular blank is in a "T" shape; and d, the tubular blank after upsetting in the step c is put into a mold cavity of the forming mold for forming, and a tee pipe is formed.

Example Embodiment

[0014] The invention provides a kind of forming method of pure nickel tee, the steps are as follows: a, select
[0015] Using the raw material, the tubular blank whose length is greater than the depth of the upset hole and whose diameter is the same as the upset hole is used as the raw material; b, injecting the solid particles deformable with pressure into the tubular blank of step a; c, the step b Put the rod-shaped billet injected with river sand into the forming mold to implement pier thickening, that is, the diameter of the upsetting part of the tubular billet increases, so that the cross-section of the tubular billet is in a "T" shape; d, the thickened tubular billet completed in step c The blank is put into the cavity of the molding die for shaping to form a tee pipe. By adding solid particles that can be deformed with pressure for pressure transmission to the raw material (tubular billet), the solid particles can on the one hand reach the pressure required for product deformation during molding, and on the other hand can act on the tubular billet during the extrusion process. It can play a supporting role, so as to ensure that the tee pipe will not wrinkle during processing, ensure the processing quality of the tee pipe, prevent waste products, not only improve processing efficiency, but also avoid production costs caused by waste products. The solid particles are preferably river sand, because the river sand is easy to collect, low in price, and has good fluidity and support in the tubular blank.
[0016] In order to further improve the oxidation resistance and corrosion resistance of the present invention, an anti-oxidation layer is coated on the surface of the tee pipe. The anti-oxidation layer is preferably a boron oxide layer.
