Latest Patents

Laird's latest patents include a header machine and a tubing expander. The header machine is designed for drilling specified hole patterns in pipes and cutting them to a specified length for use in heat transfer products. This machine features hold clamps for securely holding the pipe during processing and feed clamps for guiding the pipe through the machine. The feed carriage, driven by a stepper motor, allows for precise movement of the pipe to various drilling positions. Additionally, the machine includes a spud drill, a connection drill, a circular saw, and provisions for creating double circuit patterns of spud holes. All movements are computer-controlled, with parameters entered by the operator.

The tubing expander is a mechanical device designed for expanding tubing used in heat transfer products. It consists of elongated rods with enlargements for insertion into the tubing. These rods are supported on a carriage that moves along a frame, driven by a hydraulic motor. Clamping jaws hold the ends of the tubing securely during the expansion process. The design allows for flexibility in the number of rods and supports used, accommodating various tube configurations. A programmable logic controller manages the motion of the carriage during operation.
