Abstract

A pipe joint cold heading forming blank according to the invention is characterized in that the blank is composed of: small head (1), mounting boss (2), middle section (3), raised ring (4), tail end (5), Small channel (6) and large channel (7), the small head (1), outer hexagonal shape (2), middle section (3), raised ring (4) and tail end (5) are cold-headed into one On the whole, the small head (1) is made into a conical shape with a small top and a big bottom, and the outer circle of the upper end of the small head (1) is chamfered, and the outer circle of the lower end of the tail (5) is also chamfered. The technical purpose of the invention is to solve the technical deficiencies in the background technology. The improved blank has a smaller volume. While saving a lot of man-hours, the metal consumption can be reduced by 10% to 30%. Moreover, the product has high dimensional accuracy and smooth surface finish. Well, the production efficiency is high, which greatly improves the work efficiency and increases the economic income of employees.

Description

Technical field: [0001] The invention belongs to the field of pipe joint blanks, in particular to a pipe joint cold heading forming blank.
