Detailed description of the invention
To schematically disclose multiple embodiments of the application below, as clearly stated, the details in many practices will be explained in the following description. It should be appreciated, however, that the details in these practices is not applied to limit the application. It is to say, in the some embodiments of the application, the details in these practices is non-essential. Additionally, for the purpose of simplification is graphic, some known usual structures and assembly will illustrate it in the drawings in the way of simply illustrative.
About used herein it " ＂, " the 2nd ＂ etc., not especially censure the meaning of order or cis-position, are also not used to limit the application, and it is only used to distinguish the assembly or operation that describe with constructed term.
Referring to Fig. 1 a and 1b, it is the schematic diagram of solenoid housing assembly 1 of the application one embodiment; As shown in the figure, the application provides the production technology of the clutch coil housing unit of a kind of automobile air conditioner compressor, the solenoid housing assembly 1 of clutch includes solenoid housing part 10 and coverplate parts 11, and the solenoid housing assembly 1 producing clutch needs first to produce respectively coil housing part 10 and coverplate parts 11. Seeing also Fig. 2 and Fig. 3, it is the schematic diagram of housing tablet 101 produced by the flow sheet of solenoid housing part 10 of the application one embodiment and step S11; As shown in the figure, in this production technology first talking about open-wire line circle housing part 10, it first carries out step S10, first obtains the hot rolled steel plate of thickness 4mm, and the steel plate for meeting following process can be cut out by cutter, the banding steel plate into width 120mm first cut out by steel plate by the application. Now performs step S11, the hot rolled steel plate through cutting out carries out Blanking, produces a housing tablet 101, and its middle shell tablet 101 is round convex, and has outer surface 101a and inner surface 101b. The thin easy stretching of thickness of hot rolled steel plate, blanking scope is little also illustrates that the hot rolled steel plate forming housing tablet 101 makes consumption few, by stretching the surface area of extension housing tablet 101, make the size of housing tablet 101 reach to produce coil housing part 10 and reach to save the purpose of material.
Consult Fig. 4-7 more in the lump, its be the application one embodiment step S12 produced by the schematic diagram of the schematic diagram of housing tablet produced by the schematic diagram of housing tablet, step S16 produced by the schematic diagram of housing tablet, step S14 and solenoid housing profiled member; As it can be seen, perform step S12, housing tablet 101 is punched out processing, and is centrally formed the first perforation 102 in housing tablet 101. Now performs step S13, and the housing tablet 101 carrying out above-mentioned steps is carried out phosphatization, and it can form phosphating coat in the outer surface 101a and inner surface 101b of housing tablet 101, reaches the purpose of protective housing tablet 101. Perform step S14 again, be positioned at the inner peripheral of first perforation 102 of the inner surface 101b of housing tablet 101 by punch press processing, and form it into the first chamfering 103.Now performs step S15, housing tablet 101 carries out punch process, and forms ring-shaped groove 104 in the outer surface 101a of housing tablet 101. Then step S16 is performed, processing housing tablet 101 also makes it be shaped to solenoid housing profiled member 105, the molding mode of the application makes by hydraulic press, housing tablet 101 to be pressed, compressing pressure is between 15MPa and 20MPa, it is prevented that the inner bottom surface of solenoid housing profiled member 105 is uneven. Before performing step S16, prior to housing tablet 101 is formed the first perforation 102, it is prevented that when housing tablet 101 is pressed, housing tablet 101 produces excessive beating; So form the first chamfering 103 in the inner peripheral of the first perforation 102 again, it is prevented that when housing tablet 101 is pressed, housing tablet 101 is by pressure break; In addition form ring-shaped groove 104 in the outer surface 101a of housing tablet 101 again, increase the ductility of housing tablet 101, it is to avoid repressed molding and the height of solenoid housing profiled member 105 that obtains meets the size producing coil housing part 10. Solenoid housing profiled member 105 has toroid ring recess 1051, and the opening 1052 of the first perforation 102 and toroid ring recess 1051 is positioned at same one end, and namely the first perforation 102 is positioned at the top 105a of solenoid housing profiled member 105.
Perform step S17 again, by the top 105a of lathe lapping solenoid housing profiled member 105, make the top 105a of solenoid housing profiled member 105 smooth. Consult Fig. 8 a-10 in the lump, its be the application one embodiment step S18 produced by the schematic diagram of the schematic diagram of solenoid housing profiled member 105 produced by the schematic diagram of solenoid housing profiled member 105, step S19 and solenoid housing part 10; As shown in the figure, now performs step S18, the bottom 105b of solenoid housing profiled member 105 is carried out punch process, and forming multiple second perforation 1053 and at least one boss 1054 in the bottom 105b of solenoid housing profiled member 105, boss 1054 protrudes from the 105b surface, bottom of solenoid housing profiled member 105. Then step S19 is performed, multiple second perforation 1053 of solenoid housing profiled member 105 are carried out Drilling operation, and forming counterbore 1055 in each second perforation 1053, counterbore 1055 is positioned at toroid ring recess 1051, and its diameter is more than the diameter of the second perforation 1053. Finally performing step S20, the outboard peripheries of multiple second perforation 1053 being pointed to solenoid housing profiled member 105 carries out hair down CIJIA work, makes the outboard peripheries of each the second perforation 1053 form the second chamfering 1056. Solenoid housing part 10 is produced through above-mentioned steps.
Continuing and the production technology of coverplate parts 11 is described, refer to Figure 11, it is the flow sheet of coverplate parts of the application one embodiment; As it can be seen, first carry out step S21, obtaining thickness is the cold-rolled steel sheet of 2mm, and it can be cut out as banding steel plate by plate shearing machine. Now performs step S22, steel plate carries out blanking processing, produces a cover plate tablet. Then step S23 is performed, cover plate tablet is carried out punch process, and it is shaped to coverplate parts 11, as shown in Fig. 1 a and Fig. 1 b, coverplate parts 11 has boss 111, multiple solder joint 112 and opening 113, boss 111 is positioned at the center of coverplate parts 11, and multiple solder joints 112 are positioned at boss 111 around, and opening 113 is positioned at the side of boss 111.
After solenoid housing part 10 and coverplate parts 11 have produced, now illustrates the production technology of clutch coil housing unit 1, refers to Figure 12, and it is the flow sheet of clutch coil housing unit of the application one embodiment;As shown in the figure, first carry out step S30, being welded coil housing part 10 and coverplate parts 11 by multiple solder joints 112 of coverplate parts 11, produce solenoid housing assembly 1, wherein multiple second perforation 1053 of solenoid housing part 10 and boss 1054 are positioned at the opening 113 of coverplate parts 11. Now performs step S31, multiple solder joints 112 of solenoid housing assembly 1 are carried out punch process, plurality of solder joint 112 is the weld of coverplate parts 11 and solenoid housing part 10, when performing step S31, the surface of multiple solder joints 112 of solenoid housing assembly 1 can be made to remain smooth. Then perform step S32, solenoid housing assembly 1 carried out punch process, and in solenoid housing assembly 1 coverplate parts 11 be centrally formed hole 12, as shown in Figure 1a, finally perform step S33, remove the burr of solenoid housing assembly 1, complete the production of solenoid housing assembly 1. Above-mentioned steps S31 to step S33 is the procedure of processing to solenoid housing assembly 1 produced after welding.
