a combined lower tool apron of a slitting machine convenient to replace comprises a base, a main tool ring and a clamping ring; the base is arranged into a round cake, a shaft hole is formed in the center of the base, a positioning table is arranged on one side of the top end of the base, the positioning table is arranged in an annular shape around the shaft hole, a transverse groove surrounding the shaft hole is formed in the positioning table, a vertical groove is formed in the surface of the base perpendicular to the positioning table, and the notch of the vertical groove is perpendicular to the notch of the transverse groove; the positioning table is provided with a main cutter ring matched with the base, and a snap ring is arranged in the transverse groove in a snap-fit manner.

Furthermore, an annular bulge matched with the vertical groove is arranged on the main cutter ring.

Furthermore, the main cutter ring is arranged close to the transverse groove and matched with the outer diameter of the positioning table, and the part far away from one end is matched with the outer diameter of the base.

Further, the inner diameter of the clamping ring is matched with the inner diameter of the transverse groove, and the outer diameter of the clamping ring is arranged to the outer side groove edge of the vertical groove.

Furthermore, the main cutter ring is made of steel with hardness lower than that of the blade.

Further, the thickness of the base is set to a cumulative length of the base when the base is axially installed so that the main cutter ring can be fitted with the blades.

Furthermore, the combined method of the combined lower tool apron of the slitting machine convenient to replace and the replacement on the rotating shaft are as follows:

1) firstly, mounting a main cutter ring on a base;

2) tensioning the main cutter ring and the base;

3) clamping the clamping ring into the transverse groove;

4) mounting the combined lower tool apron on a rotating shaft, wherein the main tool ring is close to the right side during mounting, and the main tool ring on the first lower tool apron is matched with the rightmost blade for positioning;

5) sequentially mounting the lower tool apron on the rotating shaft;

6) when the tool is replaced, the lower tool apron is sequentially slid from left to right, and the rightmost lower tool apron is sequentially replaced;

7) the lower tool holder is replaced, the clamping ring is taken down, the worn main tool ring is replaced, and then the step 1) is restarted.

Compared with the prior art, the invention has the beneficial effects that:

through the use of this combination formula lower tool apron, when changing, only need sheathe the tool apron in the left side of pivot and can accomplish the change, the time of change is faster, has improved efficiency on the edgewise, simultaneously, the tool apron that gets off changed only need change main cutter ring can, very big reduction the waste of material, a main cutter ring is about 6 pieces of money, has saved 90% cost before than. Meanwhile, the main abrasion part is positioned as the main cutter ring by the design, so that the main abrasion part is convenient to replace while the cost is saved.
