T-branch pipe forming die and T-branch pipe forming manufacturing method

Abstract

The invention discloses a T-branch pipe forming die and a T-branch pipe forming method. The T-branch pipe forming die comprises an upper die and a lower die. Semicircular T-branch pipe grooves which are used for containing a T-branch pipe are symmetrically formed in the upper die and the lower die, an upsetting hole; a flattening platform and a clamping press groove are further formed in the lower die, the axis of the upsetting hole is arranged in the vertical direction, the surface of the flattening platform is arranged in the horizontal direction, and the clamping press groove is symmetrically arranged in the upper die and the lower die. The T-branch pipe forming method corresponding to the T-branch pipe forming die mainly comprises an upsetting step, a flattening step, a clamping press step, a forming step and other steps. When the T-branch pipe forming die and the T-branch pipe forming method are used, the cost and labor can be saved; due to the fact that forming is finished at one time, quality of T-branch pipe products and production efficiency are improved.

Description

technical field [0001] The invention relates to a tee pipe forming die and a forming processing method thereof. Background technique [0002] Tee pipe is a kind of pipe connector, which is mainly used in important branches of main pipes, and its application is very extensive. However, due to the special shape of the three-way pipe, it faces many difficulties in processing. In the current technology, for larger tees, the billet is generally produced by free forging, and then formed by die forging. However, this method has the following disadvantages: 1. Reheating is required, energy consumption is large, production efficiency is low, and production cycle is long; 2. Material utilization rate is low, and free forging blanks need to increase material burning loss by 3-5% , the billet precision is low, and the material cost will increase by at least 5%; 3. The quality of the billet produced by free forging is low, and it generally needs to be polished to increase the labor cos...

However, this method has the following disadvantages: 1. Reheating is required, energy consumption is large, production efficiency is low, and production cycle is long; 2. Material utilization rate is low, and free forging blanks need to increase material burning loss by 3-5% , the billet precision is low, and the material cost will increase by at least 5%; 3. The quality of the billet produced by free forging is low, and it generally needs to be polished to increase the labor cost of die forging; 4. After the billet is released by free forging, direct die forging production, oxidation The skin is difficult to remove, and the surface quality of the forging is low; 5. The blanking weight is large and the cost is high
