Description
ADJUSTABLE LENGTH PUNCH ASSEMBLY Field of the Invention
The present invention relates generally to metal working tools. More particularly, the present invention relates to punch assemblies used in punch presses. Background of the Invention.
Sheet metal may be economically fabricated into a wider range of useful products including chassis for appliances and electrical devices. Turret-type punch presses have found wide use in fabricating sheet metal. Turret-type punch presses employ an upper, generally cylindrical turret which holds a series of punch tools spaced circumferentially around its periphery, and a second, lower turret holding a series of dies circumferentially spaced about that turret's periphery, each turret being rotatable about a vertical axis to bring an appropriate punch and die pair into vertical alignment at a work station. By appropriately rotating the two turrets, an operator can bring a number of punches and dies sequentially into alignment at the work station to perform a series of sequential and different punching operations on a work piece. Repeated use of a punch assembly in a punch press operation results in the natural dulling and wear of the punch tip. Once the tip has become dull, the effectiveness of the punch assembly is reduced and the punch tip must be sharpened. Sharpening may be accomplished by grinding the end of the punch tip, and this results in shoitenmg the length of the punch. The length of the punch may then be adjusted to compensate for the ground-off portion.
The longitudinal axis of the punch assembly is typically placed in coaxial alignment with the axis of the ram. The ram of the punch press then strikes the punch with great force on it's impact surface. Summary of the Invention
The present invention relates generally to metal working tools. More particularly, the present invention relates to punch assemblies used in punch presses. An adjustable length punch assembly in accordance with the present invention may be used with a punch press including a tool holder adapted to receive the punch assembly and a ram adapted to move longitudinally along a ram axis. An adjustable length punch assembly in accordance with the present invention advantageously includes a punch body assembly disposed in threading engagement with a drive body assembly
having a surface adapted to be struck by the ram of the punch press. The length of the punch assembly may be adjusted by the rotating of one body relative to the other body. The adjustable length punch assembly advantageously includes a lock mechanism for selectively preventing rotation of the punch body assembly relative to the drive body assembly. The lock mechanism advantageously features a lock shaft coupled to one of the bodies and a lock key slidingly coupled to the other of the bodies such that the lock key slides along a lock key path.

The following detailed description should be read with reference to the drawings, in which like elements in different drawings are numbered identically. The drawings, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of the invention. Examples of constructions, materials, dimensions, and manufacturing processes are provided for selected elements. All other elements employ that which is known to those of skill in the field of the invention. Those skilled in the art will recognize that many of the examples provided have suitable alternatives that can be utilized. Figure 1 is a cross sectional view of a punch set assembly 100 in accordance with an exemplary embodiment of the present invention. Punch set assembly 100 includes a sleeve 104 and an adjustable length punch assembly 102 that is slidingly
disposed within sleeve 104. Punch set assembly 100 may be used in a punch press including a tool holder 108 adapted to receive sleeve 104 and a ram 120 adapted to move longitudinally along a ram axis 122.
In the embodiment of figure 1, adjustable length punch assembly 102 includes a punch body assembly 124 disposed in threading engagement with a drive body assembly 126 having a striking surface 128 adapted to be struck by ram 120 of the punch press. The length of adjustable length punch assembly 102 may be adjusted by rotating of punch body assembly 124 and drive body assembly 126 relative to one another. Punch body assembly 124 comprises a punch blade 130, a male threaded member 132, and a lock shaft 134. As shown in figure 1, male threaded member 132 is attached to punch blade 130 by a relatively large cap screw 136 threaded axially into a threaded bore of punch blade 130. Also as shown in figure 1, lock shaft 134 is attached to male threaded member 132 with a plurality of pins 138 and a retaining ring.
Drive body assembly 126 of figure 1 comprises a drive cap 144 and a female threaded member 146. In the embodiment of figure 1, drive cap 144 is attached to female threaded member 146 by a plurality of cap screws 140, one of which is shown if figure 1. In figure 1 it may be appreciated that female threaded member 146 of drive body assembly 126 is disposed in threading contact with male threaded member 132 of punch body assembly 124.
As mentioned previously, the length of adjustable length punch assembly 102 may be adjusted by rotating of punch body assembly 124 and drive body assembly 126 relative to one another. In the embodiment of figure 1, adjustable length punch assembly 102 includes a lock mechanism 150 for selectively preventing rotation of punch body assembly 124 relative to drive body assembly 126. Lock mechanism 150 of figure 1 comprises lock shaft 134 of punch body assembly 124 and a lock key 148 that slidingly engages drive cap 144 of drive body assembly 126 such that lock key 148 slides along a lock key path 152. In the embodiment of figure 1, the path taken by lock key 148 is defined in part by a guiding surface 154 of drive cap 144 of drive body assembly 126. In figure 1 it may be appreciated that, lock key path 152 is disposed at an angle A relative to a
longitudinal axis 156 of adjustable length punch assembly 102. In figure 1 it may also be appreciated that lock key path 152 is disposed at an angle B relative to ram axis 122 of ram 120 when adjustable length punch assembly 102 is received by tool holder 108. In a preferred embodiment, adjustable length punch assembly 102 and ram 120 are disposed in a generally coaxial relationship during punching.
In the embodiment of figure 1, angle A between lock key path and longitudinal axis 156 and angle B between lock key path 152 and ram axis 122 are both right angles. Embodiments of the present invention are possible in which, angle A and angle B are acute angles or obtuse angles. In the embodiment of figure 1 it may be noted that, lock key path 152 is generally parallel to striking surface 128 of drive body assembly 126.
Lock shaft 134 preferably has a first axial degree of freedom relative to lock key 148. In the embodiment of figure 1, lock shaft 134 is free to move along longitudinal axis 156 reative to lock key 148. This axial degree of freedom allows adjustments to be made in the length of adjustable length punch assembly 102.
Punch set assembly 100 also includes a spring assembly 158 comprising a plurality of belleville washers 160. A first end of spring assembly 158 is seated against drive cap 144 of drive body assembly 126. A second end of spring assembly 158 is seated against a spring support ring 162. Spring support ring 162 is in turn seated against a ledge 164 of sleeve 104.
During a punching operation, ram 120 strikes downwardly on striking surface 128 of drive body assembly 126 compressing spring assembly 158 and urging adjustable length punch assembly 102 downwardly until punch blade 130 protrudes below a lower face 166 of a stripper plate 168 of punch set assembly 100. The protruding punch blade 130 passes through a workpiece (not shown) to punch an item out of the workpiece having the desired shape. Punch set assembly 100 may be adaptable to a variety of punch blade shapes and matching stripper plates depending upon the shape desire to be removed from the workpiece.
Ram 120 may then be retracted, releasing the compressive force on the spring assembly 158. The spring assembly 158 then may act to draw punch blade 130 upward. When punch blade 130 is retracted upwardly through stripper plate 168 its sides may engage the workpiece which often sticks to the retreating punch blade 130.
Stripper plate 168 may engage the top face of the workpiece to assist in separating it from punch blade 130.
Repeated use of a punch blade in a punch press operation results in the natural dulling and wear of the punch blade. Once the punch blade has become dull, the effectiveness of the punch assembly is reduced and the punch blade must be sharpened. Sharpening may be accomplished by grinding the end of the punch tip, and this results in shortening the length of the punch blade. The length of the punch assembly may then be adjusted to compensate for the ground-off portion of the punch blade. Generally, when sharpening of punch blade 130 is desired, the operator removes punch blade 130 from punch set assembly 100, for example by loosening large cap screw 136. Punch blade 130 may then be sharpened or replaced. After replacing or sharpening punch blade 130, appropriate changes in the overall length of adjustable length punch assembly 102 may be made by rotating punch body assembly 124 and drive body assembly 126 with respect to one another. Lock key 148 of lock mechanism 150 selectively engages lock shaft 134 to prevent inadvertent changes in the length of adjustable length punch assembly 102. The likelihood that changes in length will occur due to the force of ram 120 striking adjustable length punch assembly 102 is reduced when lock key path 152 of lock key 148 is disposed at an angle to ram axis 122.
