  • Patent number: 6925916
    Abstract: A press for forming a workpiece with a tooling set includes an actuator assembly carrying a movable half or punch of the tooling set and having a two phase operation. In the first phase the actuator provides relatively low force in moving the punch to an intermediate position in close proximity to the workpiece. A sensor detects the position of the punch, and when the punch reaches the intermediate position provides a continue signal. The second phase of actuator operation is conditioned on occurrence of the continue signal, and uses normal high force to press the movable tooling half against the workpiece to complete the operation. The low force first phase allows obstructions of any kind to stop movement of the punch during the first phase before high force applied to the actuator may cause damage or injury to the obstruction. In a preferred embodiment the actuator assembly has hydraulic operation.

    Abstract: A process for cold forging a metal fastener such as a self-clinching standoff includes a punch and die set at the final head trimming station which produces the shear burr only on the underside of the fastener head where it is not visible after installation. At this station, a fastener blank having a tubular barrel and a temporarily formed circular head is placed into a bore of the punch with a barrel of the fastener residing in the bore with the underside of the circular head abutting an end face of the punch. The forging apparatus then moves the die toward the top side of the fastener until a polygonal cutting edge of the die shears metal from around the edges of the circular head of the fastener blank. Movement of the die stops when the cutting edge lies beyond the underside of the head of the fastener. At this point, a knock-out pin which is reciprocal within the bore of the punch forceably ejects the fastener through a passage in the die to a point beyond an opposite side of the die.

    Abstract: A punch tool including a punch driver and a punch element. The punch element can include a punch secured to a punch holder, with the punch holder and punch slidably disposed within a punch guide. The effective length of the punch tool can be increased by rotating the punch driver about threads relative to the punch element. The punch tool includes a latch mechanism for preventing rotation of the punch driver relative to the punch element when the latch is in a locked position, but allowing such rotation when the latch is in an unlocked position, thereby controlling unwanted free rotation of the punch driver relative to the remainder of the punch tool. During punching operation, the punch driver, punch holder, and punch are forced slidably relative to the outer punch guide. When a length adjustment is desired, the punch driver can be rotated relative to the punch, punch holder, and punch guide, which typically do not rotate. A locking disk can be rotatably secured to the punch driver.

  • Patent number: 6772667
    Abstract: Cast metal parts are created for use in making machinery. When these parts are formed, unwanted material remains in the openings of the parts. This material, called flash, must be removed. In the method of the present invention, the cast parts are placed on a platen of a trim press that has multi-part punches attached thereto that are configured to self-align with the openings in the cast part and operative to evenly remove the flash. The invention also relates to a punch that initially breaks through the flash with a stationary punch that removes a majority of the flash inside the opening of the cast part. Next, a moving or self-centering punch self-aligns to the opening in the cast part and operates to remove the remaining flash. The inventive punch may also include a mounting base for attachment of the multi-part punches to the plate or platen of the press.

  • Patent number: 6739244
    Abstract: A punch/emboss tool is provided that accepts interchangeable insert sets. A punch insert set consists of one punch and one die that cooperate to punch out a particular design in sheet material, such as paper. Similarly, an emboss insert set consists of one emboss die and one emboss die counter that cooperate to emboss a particular design. Once loaded in the tool, one half of the insert set is fixed relative to the tool. The other half is slidably aligned to the first half by a non-circular bore. The sheet material is inserted into a slit in the tool, between the two cooperating inserts. An actuating lever presses on the sliding half of the insert set with some mechanical advantage to the user. When a user presses the actuating lever, the two halves of the aligned insert set cooperate to form a punched or embossed design on the sheet material.
