Abstract
The invention relates to a combined die for forming a tee joint and a machining process of the combined die. The die comprises a flaring punch die and a forming punch die. The flaring punch die comprises a first base and a first punch connected to the front end of the base, wherein the front end of the first punch is arc-shaped, and a spherical body is disposed inside the first punch. The forming punch die comprises a second base and a second punch connected to the front end of the second base, wherein the second punch is formed by two punching bodies with arc-shaped front ends, and a columnar punching body is disposed between the two punching bodies. The combined die is obtained through flaring and forming. The combined die is simple in structure, low in production cost, high in forming precision and high in yield, production processes are shortened, and production efficiency is increased. The machining process is short in cycle, high in efficiency, low in difficulty, and suitable for most enterprises.
Description
Technical field
The present invention relates to a kind of mould and processing technology thereof, relate in particular to a kind of three-way forming assembling die and processing technology thereof.
Background technology
Mini three links generally adopt red copper or brass tube through multiple particular manufacturing craft, on punch press, to carry out that the multiple working procedures such as enlarging, flattening, moulding, punching bud complete, and its mould investment is large, and the manufacturing cycle is long, complex procedures, and precision is difficult to guarantee the defects such as uniformity.
Summary of the invention
The present invention provides a kind of simple in structure, easy to process, three-way forming assembling die and processing technology thereof that machining accuracy is high in order to overcome the above problems.
Technical scheme of the present invention is: described mould comprises enlarging plunger chip die and forming punching head mould, described enlarging plunger chip die comprises pedestal one and is connected to the drift one of pedestal one front end, described drift one front end is circular-arc, and drift one inside is provided with spherical; Described forming punching head mould comprises pedestal two and is connected to the drift two of pedestal two front ends, and described drift two is that the circular-arc body that rushes forms by two front ends, and two are rushed and between body, are provided with column and rush body.
The technical scheme of the inventive method is: comprise the steps:
1) adopt brass pipe to be fixed on punch press;
2) adopt enlarging plunger chip die to carry out expanding to brass pipe, enlarging is divided into twice to be carried out, until the mouth of pipe is smooth;
3) adopt forming punching head mould to carry out contour machining procedure to above-mentioned brass pipe, drift feed speed is controlled at 30-50mm/min, and repeatedly processing, until the qualified moulding of tubing.
The present invention is simple in structure, production cost is low, shortens production link, enhances productivity, and formed product precision is high, and product percent of pass is high.
This processing technology process-cycle is short, working (machining) efficiency improves, difficulty of processing is lower, is suitable for the production and processing of most of enterprise.
