No. 710,000 Int. Cl. BZlk /20 US. Cl. 76-4 6 Claims ABSTRACT OF THE DISCLOSURE A work table particularly adapted for use by tool makers when finishing dies and mating cooperating die halves in which the Work table includes a first support member having means to clamp one die half for mating with a second die half supported on an intermediate support member, which intermediate support member is reciprocable toward and away from first member by means of a machine screw whereby mating of the respective dies can be accurately and readily tried to facilitate hand finishing of the dies as well as providing a truck for readily transporting and storing finished dies.

Tool and die makers are particularly skilled in the production jigs, pressing and molding dies, etc., and although the preliminary work is accomplished by casting, milling, boring, etc., the final hand finishing of the dies, often up to .0001 of an inch, is a prolonged trial and error process.

Where male and female include complementary surfaces, the die maker must continually mate or try the die halves to determine high and low spots, wherein material must be removed. Many dies are relatively heavy and are diflicult to handle, and because the amount of time used in their production, special care must be taken to protect the dies while they are being finished, stored and transported, i.e., from tool room to the press on which they will be installed.

Primary objects of the present invention are to provide a novel die supporting work table, storing and transport truck in which a novel adjustable elevating structure is provided for an intermediate support member, in which a novel auxiliary support member can be installed in oriented relation to the intermediate support member and in which the respective support members include means for mounting mating die halves so that they can be readily tried during final finishing and which provide means for readily storing, transporting and installing finished dies.

These together with other and more specific objects and advantages of the invention will become apparent from a consideration of the following description when taken in conjunction with the accompanying drawing forming a part hereof, in which:

FIG. 1 is a perspective view with die halves supported on upper and intermediate support member;

FIG. 2 is a view similar to FIG. 1 with the die halves being moved toward mated relation;

FIG. 3 is a perspective view with the upper support member removed;

FIG. 4 is a vertical section taken substantially on the plane of line 44 of FIG. 5; and

FIG. 5 is a top plan view of FIG. 1.

Referring to the drawing in detail, the work table is indicated generally at see FIG. 3, and comprises a base or pedestal .12 produced by welding side and end frame elements 14 and 16, respectively, to form a rectangular frame. The frame elements preferably comprise angle elements and the side frame elements 14 include vertical flanges 18 and inwardly turned lower flanges 20. Secured to the outer surface of flanges 18 adjacent the corners of the frame are caster wheel assemblies indicated generally at 22. Extending transversely between the elements 14, at a medial portion thereof, are bracing angles 24, and integrally secured between the bracing angles 24 at the juncture of

flanges

18 and 20 are the lower ends of tubular guide elements 26.

Connected to the pedestal or base 12 is jack means indicated generally at 28. The jack means comprises an articulated link structure which is operatively connected to a suport member indicated generally at 30.

The support member includes a machined upper surface 32 for receiving thereon a first die half A. The support member 30 includes depending side and

end flanges

34 and 36, respectively, and conveniently includes a transverse handle 38 at one end. The support member 30 has secured at a medial portion, adjacent the side flanges 34, support brackets 40; see FIG. 4. The upper ends of guide rods 42 are secured in the brackets, and the lower ends of rods 42 are telescopically received in the tubular guide elements 26. The sleeves 26 and rods '42 in conjunction with the jack means 28 restrict the support member 30 in a vertical path of movement.

The jack means 28 comprises similar articulated link assemblies 44 at opposite sides of the table 10. Each assembly 44 comprises outermost upper and

lower links

46 and 48, respectively, which are respectively pivotally connected at 50 and 52 to opposite ends of

side flanges

46 and 48, respectively, which are respectively pivotally ends of the

side flanges

34 and 18 are ends of inner links 58 and 60. Extending transversely between terminal or inner ends of

links

46, 60 and 48, 58 are

force transmitting bars

62 and 64, respectively, which are pivotally connected to the inner ends of the respective links as indicated at 66 and 68. A first intermediate link 70 is pivotally connected at 66 at one end, and is pivotally connected at 72 to an intermediate portion of link 58. A second intermediate link 74 is pivotally connected at 68 at one end, and is pivotally connected at 76 to an intermediate portion of link 60. It will be noted that the

outer links

46 and 48 include outer flanges which rigidify and stabilize the jack means 28.

The pairs of

links

46, 48, 58, 60, 70, 74 are respectively retained in parallel relation by virtue of the pivotal connections with each other and the base 12 and support member 30. When force is applied between

bars

62, 64, the angular relationships between the links is changed, but the parallel relationships are maintained.

The

force transmitting bars

62 and 64 have extending through central portions thereof coaxial bores 78 and 80, respectively, the former being internally threaded; see FIG. 4. The threaded bore 78 will be a relatively fine machine thread so that extremely fine vertical adjustments of support 30 can be effected. A control shaft 82 is intermediately journaled in bore and includes a threaded portion 84 engaged in bore 78. The shaft 82 includes a terminal stop 86 to prevent accidental removal of the shaft 82 from the bore '78. Fixed on shaft 82 at opposite sides of bar 64 are abutment elements 88 and 90. Fixed to the other end of shaft 82 is a crank or operating handle 92.

Before describing additional structure, it will be understood that rotation of shaft 82 in one direction or the other will cause the

bars

62, 64 to move toward and away from, causing the

pivots

66, 68 to move toward each other, and force is transmitted through

intermediate links

70, 74 whereby the support member is adjusted in constrained horizontal movement relative to the base or pedestal.

The structure just described permits dies to be readily transported, i.e. to the machine on which it is to be installed, and vertical adjustment of the support member 30 permits the die to be oriented in coplanar relation with portions of a molding apparatus onto which the die will be moved, and/or the support 30 can be oriented to a convenient position permitting the tool maker to work on the dies.

The support member 30 has extending through the surface 32 transverse apertures 94 which are coaxial with apertures 96 in the flanges 20 of the side frame elements 14.

Removably received in apertures 94 are rods or legs 98 which include reduced diameter, lower portions 98 seated in the apertures 96. The legs 98 project a substantial distance above the support member 30 and include upper reduced diameter end portions 100 removably receiving thereon an upper support member indicated generally at 102. The support member comprises a rectangular frame having formed in

side frame elements

104 and 106 suitable apertures received on the portions 100 of legs 98. The frame 102 has extending between end frame elements 108 and 110 a pair of spaced brace elements 112 and 114 forming a slot 116 therebetween. The slot 116 accommodates therein suitable clamp elements or the like such as C-clamps 118 from which are suspended a second die half B.

As seen in FIGS. 1 and 2 the support member 30 can be adjusted in constrained relation with respect to support member 102. The member 30 is not only mounted in a fixed path of vertical travel by the cooperating sleeves and

rods

26, 42, and the jack means 28, but is also guided in movement by the legs 98 which project through apertures 94.

When the die half B is mounted on support member 102, the member 102 can be readily transferred and positioned on the legs 98. The die half B can be readily deposited and oriented on surface 32 of member 30, and the member 30 can be readily raised and positioned in mating relation with respect to the die half B. Likewise, the support 30 can be readily lowered to permit hand finishing of die A or B. Further, when transporting the dies A and B to an installation site, the dies can be positioned in mating relation to, and in prohibiting accidental dislodgement of, the dies off the truck.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is only limited as indicated in the appended claims.
