Edge cutting knife device and fin mold provided with edge cutting knife device

Abstract

The invention discloses an edge cutting knife device and a fin mold provided with the edge cutting knife device. The edge cutting knife device comprises a knife rest, an upper edge cutting knife, an lower edge cutting knife and a resetting mechanism, wherein the knife rest is provided with blanking holes and air holes; a lower blade is arranged at the upper end of the lower edge cutting knife; the upper edge cutting knife is mounted on the knife rest in an upward and downward moving manner and positioned above the lower edge cutting knife; a main upper blade is arranged at the lower end of the upper edge cutting knife and matched with the lower blade for cutting a waste material; an auxiliary upper blade is arranged at the lower end of the upper edge cutting knife; a middle edge cutting knife is mounted on the knife rest; and a middle blade is arranged at the upper end of the middle edge cutting knife and matched with the auxiliary upper blade for cutting the waste material short. The edge cutting knife device has the functions of cutting off the waste material and cutting the longer waste material into two short sections; the problem that the edge cutting waste material is blocked due to the fact that the edge cutting waste material is too long is solved; the waste material recovering condition is improved; the normal production of a fin is ensured; and the unnecessary shutdown rectification is reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a side cutter device and a fin mold with the side cutter device. Background technique [0002] At present, the function of the fin edge cutter device is to cut and arrange the two edges of the fins, that is, to cut off excess waste materials along the feeding direction of the fins, and to regulate the width of the fin parts. The existing side cutter device is mainly composed of a knife seat, an upper knife for side cutting, a lower knife for side cutting, and a reset mechanism. On the knife seat and above the blanking hole, the upper end of the side cutting knife has a lower blade, and the side cutting upper knife can be moved up and down on the knife seat and is located at the edge of the side cutting knife. Above, the lower end of the edge cutter upper knife has an upper blade, the upper blade cooperates with the lower blade to cut off waste, an air channel is arranged on the edge cutter upper knife,...
