10. A V-belt manufacturing method, characterized in that the V-belt slitting and chamfering device of claim 9 is used for manufacturing V-belts, and the method comprises the following steps:

presetting a cutter: the cutter feeding component II (43) pushes the barrel blank slitting cutter (41) to move along the Y direction, so that the distance between the chamfering cutter component (52) and the barrel blank slitting cutter (41) in the Y direction is a V-belt width;

(II) positioning a starting end: moving the cutter bracket (40) along the Y direction to align the chamfering cutter assembly (52) with one end of a blank (6), wherein the blank cutting cutter (41) is positioned at the inner side of the end;

(III) cutting and chamfering:

i, rotating the barrel blank; starting the V-belt forming roller, wherein the barrel blank (6) rotates along with the V-belt forming roller (2);

ii, slitting and chamfering: starting the barrel blank cutting tool (41), and pushing the barrel blank cutting tool (41) to approach the barrel blank (6) and cut the barrel blank (6) by a tool feeding component I (42) to form a cutting seam (60); simultaneously starting the chamfering tool assembly (52), pushing the chamfering tool assembly (52) to approach to the barrel blank (6) by a tool feeding member III (53), and chamfering and cutting the end face of the barrel blank (6);

iii, controlling the return stroke of the barrel blank slitting cutter (41) and the chamfering cutter assembly (52), and moving the cutter bracket (40) along the Y direction by a displacement of the width of the V belt;

iv, according to the method in the step ii, controlling the barrel blank slitting cutter (41) to slit the barrel blank (6), and simultaneously controlling the chamfering cutter assembly (52) to chamfer and cut the cutting surface corresponding to the cut-out cutting seam (60) cut in front;

and v, continuously slitting the barrel blank (6) according to the method in the steps iii and iv, and simultaneously chamfering and cutting the section corresponding to the kerf (60) until the slitting is completely finished.
