Abstract

The invention belongs to the technical field of broach equipment, and particularly relates to a broach for a heat exchanging tube. The broach comprises a machining table, a tube clamp, an upper half ring, a lower half ring, springs, a linear motor, a rotating handle, a positioning device, a flexible push rod, a broach body, a channel and a broach head, wherein the tube clamp is arranged on the left of the upper side of the machining table and comprises the upper half ring, the lower half ring and the springs; the lower half ring is fixed on the machining table; two sides of the lower half ring are correspondingly connected with the upper half ring through the springs; the linear motor is fixed on the right of the upper side of the machining table; the rotating handle is arranged in the middle of the rear side of the linear motor; the positioning device is arranged on the upper side of the linear motor; the flexible push rod is arranged in the middle of the front side of the linear motor; and the front of the flexible push rod is in threaded connection with the broach body. The broach for the heat exchanging tube is high in cutting uniformity and high in cutting efficiency.

Description

technical field [0001] The invention belongs to the technical field of broach equipment, in particular to a broach used for heat exchange tubes. Background technique [0002] At present, the broach is a forming tool used for broaching. When the inner heat exchange tube of the air cooler of the offshore motor breaks, the heat exchange medium will flow into the flow channel through the hydrophobic groove on the outer heat exchange tube, so a broach is required The pipe wall of the outer heat exchange tube is cut into water-repellent grooves. The broach in the prior art includes a broach main body, and a plurality of cutter teeth are arranged on the broach main body, and a chip container is arranged between two adjacent cutter teeth. Groove, the main cutting edge of the cutter teeth is concave along the broaching direction, the broach body also includes a broaching base plate, a plurality of cutter teeth are arranged in one or more rows on the broaching base plate, and the broa...
