The operation principle of utility model is summarized as follows:
The axle housing of such card 4 × 2 vehicle drive axle is to be processed into by the thick hot rolled plate of 6.0mm is stamped, Just can be used for the processing of shaving die after molding procedure:
The first step, this utility model mould is arranged on single-point enclosed steam-operating 1600T forcing press, and by control valve 17 Connect with the compressed air interface of lathe.
Second step, as shown in Fig. 2 the axle housing cut after long operation is cut long part 14 be placed on the upper of trimming retainer plate 18 Surface and the right edge of trimming punch assembly 9,10,11,12 right side trimming inner ring locating piece 20, and make axle housing cut long part Rear and front end end face is placed between two pieces trimming locating piece 19 inner face;By cutting, the axle housing after a line operation is monolateral to be cut Part is placed on the upper surface of trimming retainer plate 18 and a left side for trimming punch assembly 9,10,11,12 left side trimming inner ring locating piece 20 Side, and so that the rear and front end end face of the monolateral cut piece of axle housing is placed between two pieces trimming locating piece 19 inner face.
3rd step, opens the control valve of control valve 17, makes four trimming clampings on left and right sides trimming retainer plate 18 Cylinder 15 piston head simultaneous ejection simultaneously, and the axle housing of the left and right sides is cut in long part and the monolateral cut piece of axle housing Type face is in close contact formation axle housing trimming positioning with the outer mold surface of trimming inner ring locating piece 20.
4th step, starts that long part 14 cut by forcing press to axle housing and the monolateral cut piece of axle housing carries out punch process, machine Work platformses, the first trim die assembly 5, the second trim die assembly 6, the 3rd trim die assembly 7 and the 4th trimming on bed Die assembly 8 moves downward, and in the process, trim die fixed seat 4 is contacted with upperpush rod 24 and continues to move downward, trimming Retainer plate 18 and axle housing cut long part 14 and the monolateral cut piece of axle housing will with bearing spring 28 because compression produce elastic force with It to move downward together.Meanwhile, described first to fourth group of trim die assembly 5,6,7,8 cuts long part with axle housing Synchronously contact with the monolateral cut piece of axle housing and continue to move downward, trimming interfix device and axle housing cut long part and bridge The monolateral cut piece of shell body will move downward with it because compression produces elastic force together with connecting rod stage clip 22, work on lathe Till platform runs to bottom dead centre.
Axle housing cuts long part and the monolateral cut piece of axle housing in first to fourth group of trim die assembly 5,6,7,8 and One to the 4th group of trimming punch assembly 9,10,11,12 collectively constitutes in the trimming die cavity on two articles of sides of axle housing and completes trimming, reaches To two ends end dehisce width 70.2 mm in the range of φ 75.3 mm, flange face φ 250 broad in the middle, flatness 0.9 mm, in Anaplasia cross-sectional length 390.5 mm, inner chamber radius R89.3 mm, R15.2 mm, inner chamber and profile wall thickness 22.8 mm, through cutting Bian Hou, the structure of workpiece is as shown in Figure 3, Figure 4.
5th step, work platformses and part of the upper die return upwards on lathe, bearing spring 28 and connecting rod stage clip 22 can be synchronous Release release elastic force makes trimming retainer plate 18, trimming interfix device and the bilateral cut piece of axle housing and axle housing is monolateral cuts Part moves upwardly together until the bilateral cut piece of axle housing and the monolateral cut piece of axle housing and first to fourth group of trimming punch group Till part 9,10,11,12 upper surface departs from.
6th step, the control valve of control valve of closing 17, make four trimming clampings on left and right sides trimming retainer plate 18 The leading section of cylinder 15 synchronized callback simultaneously, can make in the bilateral cut piece of axle housing and the monolateral cut piece of axle housing of the left and right sides Type face is separated with the outer mold surface of trimming inner ring locating piece 20.
Tailing after trimming is first put in ash can with handss by the 7th step, then by trimming retainer plate 18 upper surface The bilateral cut piece of axle housing in left side is taken out and is loaded in body feed tank, then by the axle housing on the right side of trimming retainer plate 18 upper surface Monolateral cut piece is placed on upper surface and trimming punch assembly 9,10,11, the 12 left side trimming inner ring locating piece of trimming retainer plate 18 20 left side, and make the monolateral cut piece of axle housing rear and front end end face be placed on two pieces trimming locating piece 19 inner face it Between, then by the axle housing cut after long operation cut long part be placed on the upper surface of trimming retainer plate 18 and trimming punch assembly 9, 10th, the right edge of 11,12 right side trimming inner ring locating pieces 20, and make the rear and front end end face that axle housing cuts long part be placed on two Between part trimming locating piece 19 inner face.
Repeat the above steps, cyclic process.
Axle housing cuts long part 14, the monolateral cut piece of axle housing is according to the difference machining state name of axle housing blank , also can be collectively referred to as axle housing blank, the bilateral cut piece of axle housing is the finished parts of the present embodiment.
Axle housing overall dimensions using this utility model Mold Making are stable, two ends end dehisce φ 75.3 mm, in Between width 70.2 mm in the range of large flange face φ 250, flatness 0.9 mm, middle variable cross-section length 390.5 mm, inner chamber half Footpath R89.3 mm, R15.2 mm, inner chamber and profile wall thickness 22.8 mm, the concordance of monnolithic case is regular, sustainable stable Guarantee that the overall dimensions of axle housing reach the design requirement of product drawing.Also product is improved while improve product quality Energy, its blank trimming of axle housing trimming operation of card 4 × 2 vehicle drive axle and discharging process are very smooth and steady Fixed.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalents made using this utility model description and accompanying drawing content or the technical field being directly or indirectly used in correlation, All include in the same manner in scope of patent protection of the present utility model.
