NOTCHING The process of preparing tube & pipe ends for all types of joints have been referred to as fish mouth, coping and notching. In this section we will illustrate the notching tooling and equipment used to produce basic 90º notches for heavy stick weld construction to precision angular cosmetic joints where one can braze or silver solder the joints.

H237DN-D Automatic Load, Hydraulic Double Tube End Notch This fully automatic system will accept our 237DNI inserts for notching tubing or pipe up to 2” Standard (2-3/8” OD X .154” wall). A hopper fed system, will notch both walls of both tube ends of a single tube each cycle. Along with standard 90º radius notches, custom configurations are possible. An operator will load a bundle of tubes into the hopper holding approximately 250 tubes. The tubes are then fed into a magazine for loading into the clamp station. Once in location the tube is clamped in position, the notching heads are shuttled in and then the notching heads cycle simultaneously completing the notching operation. Upon completion of this cycle, the tube is unclamped and discharged onto an inclined run off ramp. Customer is responsible for means of collecting notched tubes from ramp.

H237DN-D Auto Feed Double End Tube Notch This manual load/unload system will accept our 237DNI inserts for notching rounds, squares, rectangles and special shapes of tubing and pipe up to 2” standard (2-3/8” OD x .154” wall). The unit will notch both walls of both tube ends in a single cycle. Along with standard 90º radius notches, custom configurations are possible. The operator will manually load the tubes into a nesting area between the H237DN notching heads and depress the dual palm buttons to cycle the system. One head will move into position (approximately 4-1/2” – 5”) and cycle notching both ends of the tube. The notching head will now retract and the operator will manually remove the notched tube.
