Abstract
The invention relates to a processing method of an automobile desiccant shell, which adopts a round pure aluminum (L2) blank with the nominal size of 9mm and the nominal diameter of 90mm, and completes the forming and manufacturing of a desiccant shell part at one time by adopting a cold extrusion forming process method at normal temperature. The method has the advantages of simple production process, high production rate, high product appearance quality and high dimensional precision, and solves the problems of the production of the desiccant shell parts by a steel plate cold stamping method and a die casting method.
Description
Technical field: the invention belongs to field of machining, relate to a kind of processing method of automobile drier housing part.
Background technology: the drier housing is one of car dryer assembly part.Its function is mainly used in the drier that holds FA humidity.This part product drawing technology is at first by external introduction.Domesticly belong to blank producing this part technical elements.Adopt steel plate cold stamping method and pressure casting method to manufacture experimently this part once, all can't reach the designing requirement of product drawing.Subject matter is as follows: steel plate cold stamping method manufacturing process complexity, and steel plate materials is overweight, can't satisfy the designing requirement of product drawing; Pressure casting method part presentation quality is relatively poor, and the housing wall thickness is overproof.
Summary of the invention: the present invention produces the existing problem of drier housing part for solving steel plate cold stamping method and pressure casting method, a kind of processing method of automobile drier housing has been proposed, promptly adopting the thickness nominal dimension is 9mm, nominal diameter is circular fine aluminium (L2) the plate blank of 90mm, adopts the cold extrusion technology method once to finish the shaping manufacturing of drier housing part at normal temperatures.This method production technology is simple, productivity ratio height, product appearance quality and dimensional accuracy height.Reached the designing requirement of product drawing.
Description of drawings: Fig. 1 is drier housing part figure;
Fig. 2 is a drier housing part cold-extrusion shaping schematic diagram;
Fig. 3 is a drier housing part cold-extrusion shaping mould punch physical dimension parameter schematic diagram;
Fig. 4 is a drier housing part cold-extrusion shaping mould die physical dimension parameter schematic diagram;
Fig. 5 is big fillet crack blanking method and a blanking die physical dimension parameter schematic diagram continuously.
Specific embodiments: as shown in Figure 1 and Figure 2, the processing method of automobile drier housing of the present invention, be to be Φ 90mm with nominal diameter, the thickness nominal dimension is the circular fine aluminium blank 3 of 9mm, put into the die cavity of Extruding die 4, adopt the backward extrusion method once to finish the shaping of housing part 1 with punch 2.The circular extrusion blank that uses, available thickness nominal dimension are fine aluminium (L2) plate of 9mm, by big fillet continuously the method for crack stamping-out obtain, as shown in Figure 5.The lubricated of blank can adopt oxidation processes to add the stearic acid zinc powder and finish, and wherein the oxidation processing technique process is as follows:
At first alkali cleaning: after in the aqueous slkali of the sodium hydroxid of 50～60 ℃ 50～60 grams per liters, cleaning 3～5 minutes successively through the via flow hot water wash, the cold wash of flowing; Saponification then: in 50～70 ℃ 150～200 grams per liter industry fertilizer soap solutions, soaked the pool 10～20 minutes; Final drying: dry under 80～130 ℃ temperature, till parching.
Drier housing part manufacturing process comprised for two steps: earlier by big fillet continuously the method for crack stamping-out to obtain nominal diameter be Φ 90mm, the thickness nominal dimension is the circular plate blank of 9mm; Then blank is put into the Extruding die die cavity, adopted the cold extrusion technology method to be shaped at normal temperatures.Wherein big fillet is the crack blanking die continuously, and as shown in Figure 5, the physical dimension parameter of punch 5 is φ 90
-0.12 -0.1, the physical dimension parameter of die 6 is φ 90
-0.15 -0.1, fillet is R10; The cold-extrusion shaping mould, as shown in Figure 3, the physical dimension parameter of punch 2 is φ 87.6
± 0.015, as shown in Figure 4, the physical dimension parameter of die 4 is φ 90
0 + 0.05
Adopt the inventive method to make the drier housing part, production technology is simple, productivity ratio height, product appearance quality and dimensional accuracy height.
