  • the invention relates to a rear axle housing for motor 5 vehicles and especially for heavy vehicles or trucks and to the process and apparatus for the manufacture of these housings.
  • the conventional rear axle housing consists of an enlarged or bulged center section for housing the differential gear assembly and includes a pair of elongated sections laterally extending from opposite sides of the center section for housing the vehicle axle shafts.
  • these housings are manufactured by a variety of processes. Many of the small axle housings are manufactured in a single piece .of hammering and pressing in a forge die. As the vehicle size is increased however, the differential housing size also increases.
  • the large housings are usually fabricated by forging individual elements and then welding these elements into an integral housing.
  • Another object is to provide a rear axle housing fabricated by a forging process which requires less hammer force andthus allows the use of a smaller size forging press to accomplish the needed shaping.
  • a further object of the invention is to provide a forging process for producing rear axle housings wherein there is less material waste.
  • a still further object is to fabricate a housing for a vehicle rear axle wherein the individual parts can be fabricated from a rough billet to the semi-finished part in one forging heat operation.
  • Another object of this invention is to provide an economical forging process for a rear axle housing wherein the housing is fabricated by using open die shapes which are considerably more economical to use than the conventional three-dimensional dies.
  • the rear axle housing of this invention is characterized in that it consists of two halves which are welded together along the central longitudinal axis. The joining seam extends along the entire length of the axle housing. These forged halves have various wall thicknesses in the longitudinal direction depending upon the stress requirements of the housing.
  • the forging process utilized in this invention results in a semifinished flat blank of irregular external contours and varying thicknesses from which the finished housing half is formed.
  • the manufacturing process starts with a rough billet of square or round crosssection which has been heated to the limits of the forging temperature.
  • the billet is then stretched and rolled until the proper material distribution for the following forging process is obtained. This material distribution is designed so that the necessary thickness and shape of the finished product can be obtained with a minimum of waste.
  • the preformed billet is moved immediately to the forging dies where it is pressed and hammered in several successive steps into a semifinished flat forging blank.
  • This intermediate forging process first laterally displaces excess material by the use of a narrow tool along the entire length. Using progressively wider tools, the blank is widened to its finished dimension and then central lobes are formed for the differential housing portion. After cutting to the proper length, the semifinished blank is then roll-forged into the finished housing shape. All of this is accomplished in successive steps and in rapid progression so that only a single heating of the original billet is required during the entire forging and shaping process.
  • the semifinished flat blank is pressed and rolled into the finished form wherein the excess material along the welding seam and at the lobes is removed by a rough machining process.
  • the halves are then welded to form the. finished rear axle housing. It can be appreciated that in a horizontal longitudinal weld seam such as this, the bending stresses in the finished product are distributed across the parent material and are not concentrated in the welded joint.
  • the apparatus of this invention which is designed for flat forging of the preshaped billet incorporates a bottom and top die member.
  • the die impressions are wider at their surface than the width of the semifinished blank.
  • the semi-finished blank or the top die may be displaced rapidly and reliably across the bottom die tool to the various pressing or forging locations. All movement of the blank or top die across the die surfaces is accomplished by mechanical means which rapidly and reliably positions the blank or upper die in the correct position.
  • the entire process can be accomplished by the single heating of the original billet.
  • the blank can be moved across impressions in the bottom die face or the top die face can contain the impressions and be moved in steps across the stationary blank and bottom die.
  • FIGS. 1 through show the progressive shaping of a rear axle housing from the rough billet to the finished product when processed in accordance with this invention
  • FIG. 16 shows a top plan view in diagrammatic form of a machine of this invention having three forging locations for forming the preformed billet into the semifinished blank;
  • FIG. 17 shows a sectional view of the machine taken along the line XVlI-XVII of FIG. 16; I
  • FIG. 18 shows a partial sectional view taken along the line XVIIIXVIII of FIG. 16;
  • FIG. 19 shows a partial sectional view taken along the line XIX-XIX of FIG. 16;
  • FIG. shows a side sectional view of the machine taken along the line XXXX of FIG. 16;
  • FIG. 21 shows a side sectional view taken along the line XXI-XXI of FIG. 16;
  • FIG. 22 shows a sectional view in diagrammatic form taken along the line XXII-XXII of FIG. 20;
  • FIG. 23 shows a sectional view in diagrammatic form taken along the line XXIII-XXIII of FIG. 21.
  • each half of the rear axle housing 1 of'this invention originates from a rough billet 2.
  • the rough billet 2 after being brought to forging temperature is rolled and stretched to the preformed billet shape 3 shown in FIG. 2.
  • the preformed billet 3 is designed for optimum material distribution for subsequent forging operations.
  • the billet 3 isthen straightened and aligned and positioned within a forging press. In three forging operations or steps, the preformed billet is shaped into a flat blank, shown in stages 4 and 5, and then to the semifinished flat blank 6.'
  • the first two steps are accomplished with a relatively narrow top die surface in conjunction with a flat bottom die impression so that the portions of the preshaped billet 3 corresponding to the lateral portions 4a and 5a of the subsequent housing half are pressed to their final dimensions.
  • the remaining portions 4b and 5b of the blank are left incomplete.
  • the FIGS. 4, 5, 6, 7 and 8 show in detail the external shaping of the flat blank (stages 4 and 5) in the first two operations.
  • the enlarged central portion la of the housing for the differential gear assembly is formed.
  • the external shape of this portion of the blank 6 has four lobes 7 in a central portion 6a.
  • the central portion 6a is slightly upset or deformed while the pressing or forging operation forms the lobes 7 and the burr 8.
  • the waste material due to the burr 8 is held to a minimum.
  • FIGS. 12 and 13 the rear axle housing half is shaped and forged from the final semi-finished blank 6.
  • FIGS. 14 and 15 show a rear axle housing fabricated from the housing halves of FIG. 12 and welded together in a horizontal plane.
  • the weld seams 11 are shown extending in a longitudinal direction and lying in a horizontal plane through the longitudinal axis. As can be seen, this seam lies in an area wherein the stresses are minimal with respect to the bending moments applied to the housing during use.
  • the forging press 12 for the intermediate forging steps is composed of a bottom tool 9 having a plane or profiled surface on which the preformed billet 3 is positioned.
  • the bottom tool or die 9 may be a multi-part die or a single surface having multiple die profile or impression locations such as the three press-forming locations 13, 14 and 15 having central, parallel longitudinal axes.
  • the top die 10 works in conjunction with the press locations 13, 14, 15 forming the preformed billet 3 into the flat semifinished blank 6.
  • a conveyor device 16 moves the preformed billet 3 into an aligning device 18 where the billet is straightened for the subsequent forming operations.
  • the aligned billet is then positioned in the forging position 13 and then from this position to the subsequent positions 14 and 15.
  • the blank 6 is then moved from the forging press by a pusher device 61.
  • a conveying device 16 which can be in the form of an endless belt receives the preformed billet 3 and moves the billet to the aligning device 18.
  • This device has jaws 19 arranged on levers 20 mounted for pivotal movement about the shaft 21.
  • the elongated jaws 19 are shaped to align with the enlarged sections and the straight sections of the preformed billet and are moved together by a hydraulic cylinder assembly 22.
  • the levers 20 are connected together by a cross-beam frame 23, 24. The subsequent rotating and squeezing of the preformed billet 3 between the jaws l9 properly aligns and straightens the billet for the subsequent forging operations.
  • the straightened billet 3 is moved by the conveyor 16 toward the bottom die 9 and is pushed onto the surface of the die 9 by the pushin device 25.
  • This device 25 is aligned laterally with the first forge forming location 13.
  • the pushing-in device 25 is mounted for pivotal movement about the. shaft 26 and is pivoted downwardly so that the rod 27 and the guide element 30 can engage the end of the preformed billet 3.
  • the guide rod 27 is extended by the pistoncylinder unit 29.
  • the fork-like guide element 30 which consists of the lateral jaws 31 grips the end of the preformed billet 3 and guides it in the longitudinal axis into proper position on the bottom die 9.
  • An adjustable stop 32 is positioned at the end of the forging position 13 to properly limit the longitudinal movement of the billet 3.
  • the stop 32 is guided in the retaining means 33 and may be pivoted out of position by the pivotal attachment 34.
  • Transverse displacement of the preformed billet 3 across the surface of the bottom die 9 is effected by means of a push strip 35.
  • the strip 35 has an outer extending edge which is profiled to correspond to the general contours of the preformed billet 3 and the flat blank stages 4, 5.
  • the strip 35 is connected to a pair of extendable guide rods 37 which are mounted in pivot means 38.
  • the guide rods 37 are designed as pistoncylinder units.
  • the pivot means 38 is secured to a mounting pedestal 39 attached to the side of the forge press 12.
  • stop rods 41 are hingedly attached to the back edge of the strip 35 and serve for limiting the stroke of the strip35.
  • adjustable stop screws 42 Arranged on the rods 41 are adjustable stop screws 42 adapted to abut against a stationary stop 43.
  • the flat blank 4 is moved to the first step position.
  • the adjustable stop screw 42 thus limits the stroke of the strip 35 to properly position the flat blank 4.
  • the push strip 35 is then withdrawn prior to the forging operation.
  • the flat blank 4 is again transversely moved across the bottom die 9 by the push strip 35.
  • the piston cylinder units 44 have rollers 46 attached to the top of the push elements 45.
  • the rods 41 are elevated so that the adjustable stop screws 42 can no longer engage the stationary stop 43.
  • the strip 35 can be extended so that the blank 4 can be moved to the second press-forming location 14.
  • a second pair of stop limiting rods 48 is hingedly attached to the back edge of the push strip 35.
  • These rods 48 also include adjustable stop screws 47 which are adjusted to limit the movement of the push rod 35 to accurately position the blank 4 at the second forging location 14.
  • the stop screws47 impinge against the stationary stop 43.
  • the pressed flat blank 5 is moved to the third forge forming location 15.
  • the stop arms 48 are pivoted upwardly by the extending cylinders 50 so that the stop screws 47 will also pass over the stationary stop 43.
  • a fixed stop 51 and a pivoted stop 52 are provided to limit the trans-.
  • the pivoted stop 52 is adapted to be moved by the piston cylinder unit 53 and is mounted on the bracket 55 by the shaft 54. This pivoted stop 52 is necessary in order that the final flat blank 6, which has completed the third forming operation 15, may be extracted and moved in the direction of the arrow 56. The stop 52 impinges against the projecting lobe 7 and the burr 8 to effect this movement.
  • a lift-out or extraction device 57 is provided at the end of the flat die position 15.
  • This device consists of a lever 58 'which is .pivoted about the shaft 59.
  • the free end of the lever 58 is moved by a piston cylinder unit 60.
  • the end of the semifinished blank 6 is lifted above the surface of the bottom tool 9 so that the pushout device 61 with its projecting nose 65 can extend under and engage the bottom surface of the end of the blank 6.
  • the guide rod 62 of the pushout device 61 is formed in a square cross-section to prevent rotation.
  • the sides of the guide rod 62 are guided by rollers 63 and 64.
  • guide rollers 63 and 64 are mounted on the frame 66.
  • One roller 64 is mounted on the rocker arm 67 which is pivotal about the shaft 68 and biased upwardly by the spring 69.
  • the pair of rollers 63, 64 may be driven by any means such as a motor to extend and retract the push rod 62.
  • the blank 6 thus is moved longitudinally across the bottom die 9 and outwardly in the direction of the arrow 56 to the final forging and shaping operation.
  • the lobes 7 and the .burr 8 provide a projecting sliding surface so that the blank 6 can be'moved across the forging die impression.
  • the top die can contain a series of die impressions and be stepped across the stationary flat blank resting on the bottom die 9.
