6 Claims. (01. 101-4) This invention relates to machines for stamping or marking articles with characters, letters or the like. I
The principal object of the invention is to provide an improved machine for marking bolts, studs and the like which is easy to operate. and readily adaptable to a wide variety of lengths and sizes of studs with a minimum of time-consuming adjustments.
Another object of the invention is to provide a stud stamping machine which will uniformly mark the studs notwithstanding substantial variations in the actual dimensions of studs of the same general size.
Another object of the invention is to provide an improved marking machine which can be easily adjusted to mark bolts, studs and the like with characters or letters at either end or at both ends.
Another object is to provide a strong, sturdy machine of inexpensive and simple design which will operate indefinitely without breakdown or repairs. v
A preferred embodiment of the invention is shown in the accompanying drawings in which:
Figure 1 is a side plan view of the machine;
Fig. 2 is a front plan view of the machine;
Fig. 3 is a top plan view of the machine;
Fig. 4 is a horizontal sectional view of the ma chine taken on line 4--4 of Figure 1;
Fig. 5 is a vertical section taken on a central plane passing forwardly and rearwardly through the machine;
Fig. dis a detailed sectional view showing the die and mandrel in the mid-course of the stamping action; and
Fig. '7 is a view similar to Fig. 6 showing the die and mandrel in the completed stamping position.
The machine, in general, comprises a circular horizontal table assembly I mounted on a base 2, a plurality of fixtures or bushings 3 circularly arranged on table assembly I and disposed vertically to receive studs 4 or the like and carry them for marking between a set of dies, and power means coordinated to operate the table assembly I and the dies to stamp either or both ends of the studs 4 as each passes therebetween.
The base 2 may consist simply of a metal frame 5 having a stationary mounting base 8 and braces 1 to hold the frame 5 upright and impart strength and rigidity to the frame.
The table assembly I comprises a circular metal plate or table 8 of suitable thicknes fitted with holes 9 to receive fixtures such as bushings 3 in which the studs are carried for marking.
The holes 9 are circularly arranged about the center of the table near its periphery, and are equally spaced circumferentially of the table. The number of holes 9 should correspond with the number of bushings 3 used and the number of studs 4 to be marked with each rotation of the table 8. In the drawings twelve holes and an equal number of bushings 3 are shown mounted in the table 8 of assembly I.
Four detent balls Ill circularly arranged about and near the center of table 8 are fitted in holes ll drilled in table 8 and extend slightly beneath the table 8. Springs I2 within holes ll position the balls l0 and are themselves secured within the holes H by plugs 13 fitted in the top of the table 8.
The table 8 is rotatively mounted so that it is supported by the four detent balls I0 which ride on the indexing table 14 and engage the ball detent seats IS in the table [4. The indexing table I4 is circular, of the same diameter as table 8, and rests upon the mounting bracket [8 extending forwardly of base 2 and bolted to the frame 5.
A pin I! having a flange I8 at its upper end extends through the centers of tables 8 and I4 and is secured in a socket [9 in the table mounting bracket 18. The flange i8 secures table 8 and maintains the detent balls H! :in contact with table l4 and the ball detent seats [5. The lower end of pin I1 is secured in the socket l9 by means of set screws 28 which permit the easy removal of the table assembly.
The bushings 3 are cylindrical, hollow-cored lengths of metal and are seated in the holes 9 of the table 8 to receive the studs 4 to be carried thereabout for marking. The bushings 3 should slide fit in the holes 9 and the studs 4 fit loosely within the cores of the bushings 3. As the table 8 rotates, the studs 4 should rest on end and slide around upon the upper surface of the indexing table l4.
The bushings 3 need only be long enough to properly hold the studs 4 upright for marking and should not be any longer than necessary for passing between the dies. The article after being marked can be easily lifted from the bushings and removed by dropping the same through a hole in plate l4 beneath one or more subsequent index positions for the articles, as shown in dotted lines in Fig. 3.
When setting up the machine for marking studs of a certain size, a complete set of bushings having cores for that particular diameter is placed in the set of holes 9 in table 8. Since bushings of a particular size may be employed for marking 3 studs of various lengths within limits, studs of the same diameter but of various lengths within those limits will requireno change of bushings.
The bushings 3, upon rotation of table 8, carry the studs 4 for marking between the upper and lower dies 2| and 22. The dies are mounted in alignment with the bushing 23 and stud 24 which are positioned closest to the frame 5 of the base 2 by the ball detent seats I5.
The ball detent seats l5 should be of sufiicient number and so arranged that, after eachof the.
successive rotational movements provided table 8, the balls in will enter corresponding seats 1 5 and secure the table 8 in position where a correspond.-
The upper die 2| is mount'ed'a substantial dis-' 4 mounted on shaft 4| and connected to pawl .36 and air valve 35 by the connecting rods 42 and 43, respectively.
The shaft 4| is mounted behind the frame 5 of base 2 and opposite table assembly I and is driven by an electric motor 44 through the pulley drive 45, clutch 46 and gear box 41.
The connecting rods 42 and 43 each have a slidable bearing 48 secured by stop nuts 49 which permit selective adjustment of their lengths. Rod 42 extends through an aperture 50 in frame 5 of base 2 to connect crank 39 with pawl 36. Rod 43 connects crank 40 with the air valve 35.
' Cranks 39 and '40 are adjusted relatively on shaft 4| sothat just after pawl 35 has engaged and rotated tablefl, the air valve 35 is moved to The lower die 22 is carried beneath table 8 and In stamping, the die 22 moves versure of the dies 2| and 22 upon the stud then 7 effects the marking of the stud 24.
The body of die 22 is cylindrical for inserting the diethrough hole 26 in the indexing table I4 and removably seating the die on mandrel 2?.
Mandrel 2'? is slidably mounted beneath the indexing table M on the supporting bracket {5. In the drawings the mandrel 2! has a cylindrical shape and slides within the hole 28 drilled in bracket i6 and in alignment with hole 28 in the indexing table i l.
The lower die 22 is moved upward and downward for stamping by the air or hydraulic cylinder 29 mounted on the rear of the frame 5. The plunger rod of the air cylinder 29 is connected to the mandrel 2'i by lever 3| and link .32. Lever 3| is pivotally mounted on the bracket support I5 at one end, extends through the aperture 33 in frame 4 and is connected to plunger rod 35 at its other end. Link 32 connects the mandrel 21 with lever 3|.
The cylinder 29 is operated by compressed air through pipe 34 and two-way valve 35 from a source not shown. The cylinder 29 may be either of two-way operation or of one-way operation against a spring, and should be of suifioient capacity to effect the required stamping;
The rotational movement of table 8 is effected by pawl 35 slidably supported on the frame 5 by any suitable means such as the slide rod 31 and engaging the notches 38 in the circumference of table 8. The slide rod 31 is mounted on frame 5 alongside the table 3. The notches 3B are evenly spaced about the circumference of table and should correspond with the holes 9 of table 8 so that with each reciprocal movement ofpawl 35 the table 8 is moved from one ball detent position to the next and successive articles are'positioned between the dies 2| and 22 for stamping.
The intermittent rotation of table '8 by pawl 36 and the intermediate stamping actions of the air cylinder actuated by air valve 35 are effected and also coordinated by two cranks 39 and 40 the position for actuating the air cylinder 29 to effect the stamping of a stud, and while pawl 36 returns to the original position air valve 35 is moved to effect retraction of the lower die 22 prior to the next forward movement of pawl 36.
If desired, the machine may be equipped with an air or hydraulic cylinder efiecting the stamping only, While the retraction of the die is effected by spring means not shown in the drawings.
The operation of the machine proceeds at a rapid rate and requires split-second timing. Any adjustments which may be required are easily made simply by adjusting the relative positions of the cranks 39 and 40 on shaft 4| and. adjusting the rods 42 and 43 by means of stop nuts 49. The rate of operation is changed without interfering with the above adjustments by simply changing the speed of rotation of shaft 4|.
The'stamping action of the air cylinder provides a uniform impact of the dies on the work and ensures impressions made therein of the desired depth notwithstanding substantial variations in the size of the work.
Adjustmentsfor marking studs or bolts of a different size are easily made. The lower die may be removed simply by lifting it from the mandrel. The upper die is accessibly mounted for easy replacement'above the rotational table. The bushings are replaced simply by liftingthem from the table'and seating others of the required size within'the holes.
A widevariety of articles other than bolts or studs and of different shapes and sizes within limits'may be marked-simply by providing suitable bushings .or fixtures therefor for carrying the articles.
Either the upper or lower die may beblank Where only one marking isdesired.
Only one operator is needed to feed the machine by dropping the articles into the bushings on oneiside ofthetable and the marked articlesare automatically dropped through the table as theyare carried to the-other side of the table. The table is set forwardly of the machine and is fully accessible for easeof operation.
