A modular guided keeper base, guided keeper assembly, and related method includes a modular guided keeper base that mounts to a die member. The guided keeper base has an integrated stop for guide pin retention. The guided keeper base can also accommodate a variety of bushings within the base. The guided keeper base is attached to a die member using a mounting flange(s). Mounting fasteners pass through the fastener holes in the mounting flanges and are anchored in the die member to securely retain the guided keeper assembly in place. A retainer ring is mounted in an associated groove in the base over the heads of the mounting fasteners to prevent unintentional unfastening of the fasteners from the die member.

A guide pin assembly includes a guide pin body that connects to a die component using retaining rings. The guide pin assembly has an upper and a lower retaining ring that permits the retention of the guide pin body in a hole in a component of a metal forming die, with each retaining ring contacting a surface of the die component. The guide pin body includes an opening to permit the temporary insertion of a device for positioning the guide pin body within the opening in the die member.

An LED growth light and method for providing light to plants incorporating a reflector housing, LED driver, and dimmable rows of LED chips on the LED growth light. The reflector housings couple to a wiring compartment that includes wiring coupled to each row of LED chips on each reflector housing. The LED driver is coupled to an exterior groove in between two adjacent reflector housings.

A pilot assembly having a shaped portion and a shaped fastener relief for attachment to a die. The pilot assembly includes a fastener with a shaped washer that engages the shaped fastener relief to permit installation and removal of the pilot from the die. The shaped portion of the pilot assembly helps to locate and center the stock down the pilot assembly toward the die.

Tapered transition pilot

An LED growth light and method for providing light to plants incorporating an LED arrangement, a growth light housing, and a power source. The LED arrangement includes LEDs arranged in individually powered columns to provide relatively uniform disbursement of the light to the plants. The housing includes an accessory rail to attach a variety of optional accessories and internal cooling fins to cool the housing to prevent damage to the power supply and/or to prevent overheating the plants. In addition, the housing includes a fan and end caps which permit the movement of air for the displacement of heat and reduce the intake of moisture or debris into the interior of the LED growth light.

A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

A tight space pilot, tight space pilot assembly, and related method includes a tight space pilot that can be installed into a die without fasteners, fastener apertures, or added blocks for mounting. The tight space pilot assembly includes ejectors that are retained by the pilot and a retaining ring that holds the tight space pilot in place in a die member.

Tight space pilot

A collar and shaft assembly utilizing a ring and a multi-stepped groove. The multi-stepped groove permits the ring to be compressed into one groove while the collar is being assembled and then to expand into a different groove that permits the ring to contact surfaces on both the collar and the shaft.

Collar and shaft assembly

A guided keeper assembly for metal forming dies includes a base having a mounting face and a fastener aperture to mount the base to an associated die shoe, as well as a central guide aperture. A guide pin having a central portion is closely received in the central guide aperture for precisely guiding reciprocal motion between the die pad and the die shoe. The guide pin has an enlarged head at one end which abuts the base to positively limit travel between the die shoe and the die pad, and a shoulder at an opposite end with an alignment mechanism that precisely locates the guide pin on the die pad. A fastener extends through the fastener aperture in the base to securely connect the same with the die shoe. Another fastener securely connects the second end of the guide pin with the die pad.
