A CORPORATION OFDELA'WARE MANUFACTURE! or; SHEET METAL WARE 1 Y Application filed January 6, 1930. Serial No. 418,854.
This invention relates to the manufacture of sheet metal ware by spinning operations and more particularly the manufacture of lamp housings for automobiles. I
One of the objects of the present inven tion is to provide a novel method and apparatus for forming a relatively narrow and deep annular groove adjacentthe periphery of a parabaloidal lamp housing in order that it may interlock with an inwardly turned flange of the lamp door rim or lens bezel ring.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein apreferred embodiment of one form of thepresent invention is clearly shown. a
In the drawings: i Y Figs. 1,2 and 3 are orosssectional views ofa lamp housing-showing the various stages in the manufacture thereof according to the method embodying the presentinvention.
Fig. 4 is a plan view partly in longitudinal cross section showing the apparatus for performing the step shown in Fig.2.
Fig. 5 :is a fragmentary sectional View taken on the line 5-5 of Fig. 4.
Figs. 6 and 7 are fragmentary plan views, partly in longitudinal cross section, of apparatus for performing the step in the method shown in Fig. 3. These figures show the apparatus in two positions of operation. 1 1
According to the present invention the first step in the method consists of spinning into a parabaloidal sheetmetal blank shown in Fig. 1, a relatively wide and shallow annular groove 21 adjacent the peripheral edge 22 thereof. In order to formthe groove 21 into the relatively narrow and relatively deep 4 groove 23 shown in Fig. 3, the blank 20 is rotated while relative axial movement. is effected'betweenthe portions .ofthe housing blank located on opposite sides of the groove 21. This relative movement may be produced by holding the peripheral edge portion performing the step of the method in Fig. 2
comprises a base which supportsa power driven shaft 31 to which is attached a spinning head 32 having a groove 33 for shaping the groove 21 of the lamp housing blank. A
formin wheel 35 cooperates with the groove form the groove 21 in the blank 1 20. The wheel 35 is mounted on a frame 36, which is 'slidable along the base 30- in a direction at rightangles to the axis of the shaft 31. This motion of the frame 36 is effected by turning a handle 37which turns a screw 38 cooperating with a nut 39 to which the frame 36 is attached. a While being operated on, the received by a work holder 40 attachedto a shaft41 mounted in'a bearing 42 whichis parallel with the shaft 31.but which is out ofalignment with the shaft 31 by an amount corresponding to the difference in diameter:
of the groove 21 to be formed in the blank and the forming groove '33 of'the spinner head 32, the latter being made smaller-than the blank 20- in order that the blank 20 may be removed from the head 32-after the groove h providing for an orbital movementof the block 43 relative to the head 32 while the head blank Q20 is 32 rotates. This connection is provided by a pin 44 having a shank 45 attached by a pin 4:6. to the block 43, having a shoulder 47 which bears against the block 43, having a head portion. 48 extending through a hole 49 of larger diameter in the head43 and having a head50 larger in diameter than the hole 49 in order that the pin 44 maybe retained in position. The distance between the shoulder 47 and the head 50 is slightly greater than the distance between the surface 51 and the right hand end surface of the block 32 so that relative lateral movement between the head 32 and the block 43 may take place freely as the spinner head 32 rotates.
The bearing 42 is supported by a support 755' which may be secured adjustably in any desired manner to a sliding frame 56 guided for movement in a direction parallel tothe shaft 31. This frame 56 is moved by lever 57 pivoted at 58 upon the frame 30 and hav- 5 ing a slot 59 for receiving a pin 60 attached to the-frame 56,. a
By moving the lever 57 counter-clockwise as viewed in Fig. 4, the work holder .tOis
' retracted from the spinner head 32 in order w that a blank 20'inay'be placed thereon. 'Then the lever 57 is moved clockwise in order to clamp the blank 20'bet ween the. pressure block 43 and the work holder 40, as shown in Fig. 4. While the blank: is maintained in this position, the shaft 31 is rotated and the.
forming wheel 35 is caused to move into the groove 38"of the head 32 in order to spin the groove 21 into the blank The apparatus shown in Figs; 6 and 7 for 20 performing the step of the method shown in Fig. 3 resembles the apparatus shown in Fig. 4. The work holder and means for mov-' ing it axially,'.are substantially the sameas in the apparatus shown in Fig. 4 and will 5 not be described in detail; The'sameis true of the movable frame which moves a spinning wheel transversely ofthe axis of the work, and 'of the pressure block which clamps the work against the work holder. Therefore the parts of these devices whicharesimilar to those shown in Fig. 41 will be designated by the same reference numerals as. in Fig. 4, except that the afiix a is added; The
two apparatuses differparticularlywith re- '35 spect to the spinner head and the spinning wheel. .The spinner head comprisestwo telescopic ally engaging parts 61 and 62, the
former being attached to a drive shaft 63' and having 'aucylindrical recess 64 coaxial with the drive shaft 68 and receiving the cylindrical shank 65 of the part 62 which is provided-with the parabaloidal' surface 66 for engaging the work. Itwill be noted that the part 62 is urged by one or more springs 45.67 toward the right with respect to the part 61, this movement being limited by a stop screw 68 received by a slot 69 located longitudinally in the side of the cylindrical shank 65 ofthe part 62. The "part 62 is shaped to provide an annular plane ledge or shoulder 70, the width of which is substantially equal to the depth of the groove 23 to be provided, as shown in Fig. 3'; and is shaped to provide [a cylindrical ledge 71, the width of which is substantially equalto the width of the'bead 230 which isformed internally with respect to the blank 20 when forming the groove 23. Normally the distance between the plane annular ledge 70 andthe right hand end surface '72 of the part 61 is wide enough to receivethe bead21 awhich forms the groove 21 as shown in F ig. 2. The head 40a being retracted from the spinner head 62, the operator will place the part provided by the groove 21 upon the head 62, the bead 210 being received between the surfaces and 72 of part 62 and 61 respectively. Then'the' work holder 4011 will be moved against the work in order to clamp it between the holder 40a and the pressure block 43a as shown in Fig. 6. While the head 62' is rotating, the
axis of the head62 inorder to cause a relatively narrow annularflange 76 of the wheel 7 5'to enter thegroove 21 of the work. The thickness andwidthof this flange 76 correspondsfsubstantially with the depth and width of the groove 23 to be formed. D-uring the squeezing together or collapsing of the side walls of the bead 28a produced by forcing thespinner head member 62 from the position shown in Fig. 6 to that shown in Fig.7, theflange 76 of the spinner wheel tends to force the bead 23a'down against the annular flange of a bezel ring or similar device used for securing a lens to the front of the lamp housing.
While the form of embodimentof the present invent-ion as herein disclosed, constitutes apreferrefd form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
'What is'claimed isas follows:
1. Apparatus for forming a; relatively wide, shallow,- annular head of a metal shell into a bead defining a relatively narrow deep groove, comprising in combination, companion spinning' members, one. of which is a wheel having a flange shaped to provide the desired bead, and the other member provides a groove variable in width for receivingv said flanged wheel, said other member including two parts, one movable axially relative to the other in order to vary the width of the groove, yet being held in a fixed position to the other part while the metal shells are being interchanged.
2.
