4th step, start forcing press to axle housing profiled member 19, axle housing cuts long part and the monolateral cut piece of axle housing carries out punch process, work platforms on lathe, cut long punch 15, first trim die assembly 5, second trim die assembly 6, 3rd trim die assembly 7 and the 4th trim die assembly 8 move downward, in the process, cut long unloading block 17 to contact then with axle housing profiled member 19 at first then move upward, trim die is fixed seat 4 and is contacted with upperpush rod 33 and continue to move downward subsequently, trimming retainer plate 27 cuts long part and the monolateral cut piece of axle housing with axle housing will be with bearing spring 37 because compression produces elastic force along with moving downward together with it.Meanwhile, described first to fourth group of trim die assembly 5, 6, 7, 8 cut long part and the monolateral cut piece of axle housing synchronizes contact and continue to move downward with axle housing, trimming interfix device cuts long part and the monolateral cut piece of axle housing with axle housing will be with connecting rod stage clip 31 because compression produces elastic force along with moving downward together with it, until work platforms runs to bottom dead centre on lathe, the axle housing profiled member 19 long punch 15 of cutting in rear and front end is made to complete to cut length with the elongated intracavity of cutting cutting the axle housing profiled member 19 two ends end face that long die 21 collectively constitutes, reach to cut length 1360.4 mm, dehisce end, two ends φ 75.3 Width 70.4 mm in the range of mm, flange face φ 250 broad in the middle, flatness 1.2 mm, middle variable cross-section length 390.5 mm, after cutting length, the structure of workpiece is as shown in Figure 4, Figure 5;Simultaneously, axle housing cuts long part and the monolateral cut piece of axle housing at first to fourth group of trim die assembly 5, 6, 7, 8 and first to fourth group of trimming punch assembly 9, 10, 11, trimming is completed in the 12 trimming die cavities collectively constituting two limits of axle housing, reach to cut length 1360.4 mm, dehisce end, two ends φ 75.3 mm, width 70.2 mm in the range of flange face φ 250 broad in the middle, flatness 0.9 mm, middle variable cross-section length 390.5 mm, inner chamber radius R89.3 mm, R15.2 mm, inner chamber and profile wall thickness 22.8 mm, after cutting long trimming, the structure of workpiece such as Fig. 6, shown in Fig. 7.
5th step, work platforms and part of the upper die upwards return on lathe, cut long discharging spring 16 to discharge elastic force and make to cut long unloading block 17 and axle housing is cut long part shoot down the elongated intracavity portion of cutting and the upper surface cutting long locating piece 20 cutting long die 21, bearing spring 37 and connecting rod stage clip 31 can make trimming retainer plate 27 by synchronous release release elastic force, trimming interfix device and the bilateral cut piece of axle housing and the monolateral cut piece of axle housing move 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 assembly 9, 10, 11, till 12 upper surfaces depart from.
6th step, the control valve of control valve of closing 26, making four trimmings on left and right sides trimming retainer plate 27 clamp the leading section synchronized callback simultaneously of cylinders 24, in can making the bilateral cut piece of the axle housing cut piece monolateral with axle housing of the left and right sides, profile separates with the outer mold surface of trimming inner ring locating piece 29.
null7th step,Ash can put into by tailing after first cutting length and trimming with hands,Then the bilateral cut piece of axle housing on the left of trimming retainer plate 27 upper surface is taken out and load in body feed tank,Then the monolateral cut piece of axle housing on the right side of trimming retainer plate 27 upper surface is placed on upper surface and the trimming punch assembly 9 of trimming retainer plate 27、10、11、The left side of trimming inner ring locating piece 29 on the left of in the of 12,And two ends end face is placed between two pieces trimming locating piece 28 inner face before and after making the monolateral cut piece of axle housing,Axle housing after cutting long operation again is cut long part and is placed on upper surface and the trimming punch assembly 9 of trimming retainer plate 27、10、11、The right edge of trimming inner ring locating piece 29 on the right side of in the of 12,And two ends end face is placed between two pieces trimming locating piece 28 inner face before and after making axle housing cut long part,Finally the axle housing profiled member 19 after molding procedure is placed on two pieces and cuts the elongated intracavity portion of cutting of long die 21 and two pieces cuts the upper surface of long locating piece 20.
Repeat the above steps, cyclic process.
Axle housing profiled member 19, axle housing cut long part, the monolateral cut piece of axle housing is named according to axle housing blank difference machining state, it is possible to being referred to as axle housing blank, the bilateral cut piece of axle housing is the finished parts of the present embodiment.
The automobile drive axle housing body using the present invention cut axle housing overall dimensions that long trimming multi-station mold makes stable cutting length 1360.4 mm, φ 75.3 is dehisced in end, two ends Width 70.2 mm, flatness 0.9 mm, middle variable cross-section length 390.5 mm, inner chamber radius R89.3 mm, R15.2 mm, inner chamber and profile wall thickness 22.8 mm in the range of mm, flange face φ 250 broad in the middle, the concordance of monnolithic case is regular, and the sustainable stable overall dimensions guaranteeing axle housing reaches the design requirement of product drawing.Also improving production capacity improving while product quality, the axle housing of card 4 × 2 vehicle drive axle cuts long and long and trimming cut by its blank of trimming operation and discharging process is the most smooth and easy and stable.Single products split run production capacity is promoted to 1350 by 630, and split run production capacity improves 114.3%.
