Shaping tool die

Abstract

A shaping tool die for shaping components from sheet material includes two matching shaping tool die halves, each shaping tool die half having a plurality of spaced plate die shapes, each die shape having a rotatable curved surface mated with a curved recess in the free end of a base mounting plate such that each plate die shape is separately adjustable relative to a mated mounting plate. A position fixing plate is associated with each plate die shape and base mounting plate combination to adjustably fix the position of the plate die shape relative to the base mounting plate in a desired position. A base member is provided for receiving the base mounting plates for each tool die half, and at least one clamp plate member threaded through corresponding base mounting plates of each die half and removably fixed to a corresponding base member is provided to fix the base mounting plates in place.

DETAILED DESCRIPTION

(9) The following description details one or more exemplary embodiments illustrating the present invention. It should be noted that the detailed descriptions are intended by way of example only and are not intended to limit the scope of the invention in any respect. It will be further understood that the embodiments of the invention can be modified by those skilled in the art while remaining in keeping with the inventive concepts.

(10) FIG. 1 is a perspective view showing assembled upper and lower shaping tool die halves 10 and 12, respectively. Each shaping tool die half includes an identical opposed base plate 14 which includes a series of front and rear slots as at 16 and 18, which are designed to hold tabs of upper base mounting plates 20 and lower base mounting plates 22 in position and secure top to bottom alignment using upper base mounting plate member tabs 26 and lower base mounting plate member tabs 28, as best shown in FIGS. 5A and 6. The upper and lower base mounting plates are further secured by front and rear clamp plates as at 30 and 32 in FIG. 1, which are shaped bars that entered the length of the disc and engage openings in all of the die base mounting plates 20 and 22 through openings 34 and 36 in the upper tool half and 38 and 40 in the lower tool half. The clamp plates are bolted to the respective base plates 14 thereby fixing the upper and lower base mounting plates in place.

(11) As best seen in FIGS. 5A, 5B and 6, each upper shaping tool half includes an associated upper plate die shape which nests in a corresponding upper base mounting plate member 20 and is able to rotate with respect to the mounting plate as the interface is a circle segment. In the same manner, each lower shaping tool half includes an associated lower plate die shape 52 which nests in a corresponding lower base mounting plate 22 and is able to rotate in the same manner. As shown in FIG. 6, the position of the upper die plate shapes 50 and the lower die plate shapes 52, once adjusted, are fixed in place by plates 54 and 56 which may be bolted between openings 58 in series in upper base mounting plates 20 and openings 60 in upper plate die shapes 50. The lower plate die shapes are fixed in place in the same manner using openings 62 and 64.

(12) The detailed description shows a particular die shape bend but it will be appreciated that the die shape can vary to any configuration and the radius of the associated die plates and mounting plates may also vary depending on the size and desired formed shape of the part or work piece formed. Also, adjacent die shapes may have different rotational positions to add a twist or different curvature. Also, the series of die shapes are shown in an arcuate or fan-shaped pattern, however, the shape may be straight or in some other configuration.

(13) FIGS. 3 and 4 show front and rear elevational views of spaced upper and lower shaping tool die halves of the embodiment of FIG. 1.

(14) It will be appreciated that the shaping tool of the invention may be made out of any of various materials including steel, plastic, wood or any other durable material depending on the forces needed to shape the corresponding work piece involved. The concept of bolting the parts together gives the assembly a great deal of adjustability and the freedom to replace or remove any individual die plates. This clearly is not possible with common welded structures and also avoids the possibility of parts being warped from the heat of the welding process.

(15) This invention has been described herein in considerable detail in order to comply with the patent statutes and to provide those skilled in the art with the information needed to apply the novel principles and to construct and use embodiments of the example as required. However, it is to be understood that the invention can be carried out by specifically different devices and that various modifications can be accomplished without departing from the scope of the invention itself.
