The threaded portion intensity of liquid storage dryer housing；Delivery outlet is provided with the tube wall of described screen pack installation portion, described is dry
Input hole is provided with the tube wall of drying prescription holding part.
The manufacturing process of the liquid storage dryer housing, is characterized in that, described manufacturing process is comprised the following steps：
The first step, backward extrusion intercepts the circular metal bar of certain length, using bar hydraulic press to the metal bar
One end is extruded, and extruding cephalic par has portable protective gaps with extruding external mold mold cavity bottoms, and Jing extrudes to form one end by protective layer envelope
The tubular body of mouth, tubulose intracoelomic cavity is step circles counterbore, and counterbore bottom section diameter is less than sealing ring installation portion internal diameter, reserves follow-up machine
The length summation of allowance, counterbore bottom section and protective layer is equal to internal thread part, sealing ring installation portion, screen pack installation portion and mistake
The length summation of filter screen spacing preiection, counterbore epimere diameter is equal to the internal diameter of drier holding part；
Second step, in-car screw thread datum hole, according to the path and length dimension of internal thread part, using lathe turning protection is got through
Simultaneously turning completes internal thread datum hole to layer；
3rd step, car sealing ring installation portion and screen pack installation portion, according to the internal diameter and length of sealing ring installation portion and
The internal diameter and length equidimension of screen pack installation portion, using turning of lathe sealing ring installation portion, screen pack installation portion are completed,
Screen pack spacing preiection is formed between screen pack installation portion and drier holding part；
4th step, in-car threaded portion completes internal thread part according to the dimensional requirement turning of internal thread；
5th step, pacifies respectively according to the aperture size of input hole and delivery outlet in the tube wall and screen pack of drier holding part
Input hole and delivery outlet are made on the tube wall in dress portion；
6th step, the plug that manufacture coordinates with internal thread part.
Following beneficial effect can be reached using the present invention：Mainly made using metal bar and by backward extrusion technology and stored up
The housing blank of liquid drier, it is possible to produce the different body of each section of wall thickness, such that it is able to increased internal thread part is arranged
Body wall thickness, while reducing other parts housing wall thickness as far as possible in claimed range, improves the internal thread for installing plug
The intensity of section, while material-saving is used, reduces material cost.
