As a more preferable embodiment of this embodiment, as shown in fig. 1 and 5, the device further includes a pressing device, the pressing device is used for further fitting reed sheets into the second chute 3 and shaping reed sheets so that reed sheets keep a bending radian consistent with the cutting edge of the finishing cutter 16 for finishing, specifically, the pressing device includes pressing rods 20, shaping wheels 21 and a connecting shaft 22, one end of each of the pressing rods 20 is hinged to both sides of the tool holder 15 through a hinge shaft, a compression spring is sleeved on the hinge shaft, the connecting shaft 22 is connected between the other ends of the two pressing rods 20, the shaping wheels 21 are sleeved on the connecting shaft 22, the pressing rods 20 tightly and movably fit the shaping wheels 21 into the second chute 3 through the action of the compression spring, and as an optimization, one of the pressing rods 20 is provided with a handle 24, the operator can conveniently lift the pressing wheel, before finish machining, the front end of the reed sheet is pressed under the shaping wheel 21, and then the second push block 8 pushes the reed sheet to move, so that the shaping wheel 21 shapes and presses the reed sheet from head to tail, and the reed sheet is contacted with the finish cutter 16 in a standard structural state and is cut.

Example 3:

in this embodiment, a method for using a reed forming machine includes the following steps:

the method comprises the following steps: roughly cutting, namely placing the split reed sheets in the first chute 2, driving the sliding plate 4 by the driving device and pushing the reed sheets to translate in the first chute 2 until the reed sheets are pushed to the position of the roughly cutting device for cutting, wherein most of the reed sheets are cut in one time and are useless, and the width size requirement is met;

step two: fine cutting, namely placing the roughly cut reed sheets in the second chute 3, driving the sliding plate 4 by the driving device and pushing the reed sheets to translate in the second chute 3 until the reed sheets are pushed to the position of the fine cutting device for cutting;

step three; and repeating fine cutting, cutting layer by layer and molding for multiple times until the size, the surface roughness and the shape of the reed sheet meet the acceptance requirements.

By adopting the method, the cutting mode of rough machining and repeated finish machining is adopted, the cutting allowance of subsequent finish cutting is reduced, the finish cutting consumption is saved, the layer-by-layer cutting is realized, the multiple forming is realized, the cutting precision is ensured, and the rejection rate is reduced.
