[0028] Example: Figure 1-9 As shown, the high-precision crusher adapted to the high-speed punching machine is arranged at the output end of the punching machine, and is used for cutting waste. The length direction of the waste is defined as the front-to-back direction. The high-precision crusher adapted to the high-speed punching machine comprises a machine base 1, the machine base 1 has a crushing channel 101 and two cutters 102, the crushing channel 101 extends forward and backward for the waste to move along it, the cutter 102 is arranged on one side of the crushing channel 101 and has a blade 103, the blade 103 extends up and down, the two cutters 102 are arranged opposite to each other up and down, the two cutters 102 can approach or move away from each other in the up and down direction, and the two cutters 102 cooperate to cut the waste when they are close to each other in the up and down direction.

[0029] When the high-precision crusher adapted to the high-speed punch press is used to punch waste, the steps are as follows: the waste is inserted into the crushing channel 101 and moves along the crushing channel 101. When the waste moves between the two cutters 102, the two cutters 102 are close to each other in the extension direction of the blade 103 to cut the waste.

[0030] In summary, the present embodiment provides a high-precision shredder adapted to a high-speed punch press to solve the problems that the angle formed by the cutting direction of the blade of the existing punch shredder and the length direction of the waste is less than 90°, the blade length is much greater than the width of the waste, the cutter is long and occupies a large volume. The shredder is mainly configured by configuring a shredding channel 101 extending forward and backward and a cutter 102 on one side of the shredding channel 101. The cutter 102 has a blade 103 extending upward and downward. The cutter 102 moves in the upward and downward directions to cut the waste, so that the cutting direction of the blade 103 is perpendicular to the length direction of the waste (the direction of waste conveying), thereby effectively shortening the length of the cutter 102, thereby reducing the volume and weight of the shredder.

[0031] In the embodiment of the present invention, the up and down direction is defined as the vertical direction.

[0032] In the embodiment of the present invention, the cutter 102 may be made of, but is not limited to, molybdenum-vanadium steel. The cutter 102 made of molybdenum-vanadium steel has the advantages of high structural strength and good cutting effect.

The above arrangement enables the high-precision crusher adapted to the high-speed punch press to have a good cutting effect by configuring two front-to-back opposite left-to-right staggered cutting knife groups 106 on the base 1.

[0034] In the embodiment of the present invention, one of the two cutter groups 106 is defined as a front cutter group 107, and the other cutter group 106 is defined as a rear cutter group 108. The front cutter group 107 has two front cutters 109 facing each other up and down, and the front cutter 109 has a front blade 110 extending up and down.

The supporting portion 104 extends left and right, and the blade portion 105 extends from the supporting portion 104 toward the other cutter 102. The blade portion 105 has a front blade 110 extending up and down. The above arrangement enables the two front cutters 109 to have a good cutting effect when they cooperate to cut waste materials by configuring the two front blades 110 to be alternately spaced left and right or located on the same vertical plane. At the same time, by configuring the cutter 102 to include a support portion 104 extending left and right and a blade portion 105 extending from the support portion 104 toward the other cutter 102, the blade portion 105 has good structural strength and is not easily retracted due to long-term stamping.

[0035] In the embodiment of the present invention, the rear knife group 108 has two rear cutters 111 opposite to each other up and down, and the rear cutters 111 have rear blades 112 extending up and down. The orthographic projections of the two rear cutters 111 in the vertical direction partially overlap. Among the two rear cutters 111, one rear cutter 111 has a base 117 and a sliding portion 118, and the rear blade 112 is arranged on one side of the base 117 adjacent to the sliding portion 118. The base 117 is fixed on the machine base 1, and the sliding portion 118 is slidably connected to the base 117 and driven by the other rear cutter 111 to move in a direction away from the other rear cutter 111. An elastic member (not shown in the figure) is provided between the base 117 and the sliding portion 118, and the sliding portion 118 is driven by the elastic member to move in the direction of the other rear cutter 111, and the elastic member is a spring. The above arrangement enables the two rear cutters 111 to have a good cutting effect when cooperating to cut off the waste by configuring the two rear cutters 111 to be opposite to each other up and down and with their orthographic projections partially overlapping in the vertical direction.

[0036] In the embodiment of the present invention, the base 117 has a positioning hole (not shown in the figure), and the end of the sliding portion 118 facing away from the other rear cutter 111 is plugged into the positioning hole.
