Latest Patents

Jun Ohbu holds a patent for a method of making a cross joint between pipes. This improved method addresses the challenges of connecting different size pipes. The invention involves a punch, die, and a pressing machine. The punch is designed with a center rest for receiving a small pipe, a curved slot, and a curved surface for transforming the end of the small pipe. Under the actuation of the pressing machine, the end of the small pipe is transformed into an arcuate configuration that matches the inside curvature of a larger pipe. This process also forms a curved bead on the small pipe, ensuring that the distance from the resultant arcuate edge is consistent with the wall thickness of the large pipe. The innovative design allows for welding or brazing the small and large pipes together, resulting in a cross joint that does not protrude into the space of the larger pipe.
