S30: the first mold 110 and the second mold 120 are controlled to separate, and the material member 160 is forced by the first elastic member 112 to pass through the material belt 150 and separate from the material belt 150 again.
Specifically, referring to fig. 10 to 12, the first mold 110 and the second mold 120 are controlled to apply opposite forces to the tape 150, the mold plate 122 is compressed by the force of the separating plate 111, the supporting member 121 applies a force F to the tape 150 until the material 160 is separated from the tape 150 and presses the first elastic member 112, at this time, the first elastic member 112 has a force F' opposite to the force F to the material 160, so as to ensure that when the first mold 110 and the second mold 120 are separated, the material 160 passes through and separates from the tape 150 again in the opposite direction, so that burrs on the periphery of the material 160 are applied with opposite forces to the burrs separated from the tape.
According to the invention, the burr-free stamping method is applied to the burr-free stamping equipment 100, and the first die 110 and the second die 120 are controlled to move to apply opposite acting force to the material piece 160, so that the burrs on the periphery of the material piece 160 are stressed and reduced or even eliminated, and the burr-free material piece 160 is formed.
In addition, compared with the mode of grinding and polishing for removing burrs of the material part 160, the method can avoid generating chips, broken slag and the like generated in the grinding and polishing process, and reduce the damage to the environment.
Further, based on the above steps, referring to fig. 1 and 3, the burr-free punching apparatus 100 further includes a second elastic member 130, the second elastic member 130 is protruded on the supporting member 121, and the burr-free punching method further includes the following steps:

6. A burr-free punching method according to any one of claims 2 to 5, characterized in that the burr-free punching method further comprises the steps of:
controlling the first die and the second die to separate, wherein the material piece is subjected to the acting force of the first elastic piece, passes through the material belt and is separated from the material belt again;
and controlling the waste material separated from the material belt to be far away from the material part.
7. The burr-free pressing method according to any one of claims 2 to 5, further comprising the steps of:
controlling a moving distance L1 of the first mold and a moving distance L2 of the second mold;
and controlling the moving speed of the first die and the second die to enable the first die and the second die to simultaneously generate opposite acting forces on the material belt.
8. The burr-free pressing method according to any one of claims 2 to 5, further comprising the steps of:
fixing the first mold;
placing a strip of material adjacent to the first mold;
and controlling the second die to move towards the first die, so that the second die and the first die apply opposite acting force to the material belt, and the material piece is separated from the material belt by the acting force of the supporting piece and extrudes the first elastic piece.
9. A burr-free punching method according to any one of claims 2 to 5, characterized in that the burr-free punching method further comprises the steps of:
placing a tape between the first mold and the second mold;
the first die is controlled to apply opposite acting force to the material belt at the starting time T1 and the second die applies opposite acting force to the material belt after the starting time T1 +/-T2, and the material piece is separated from the material belt by the acting force of the supporting piece and extrudes the first elastic piece.
10. A burr-free punching method according to any one of claims 2 to 5, characterized in that the burr-free punching method further comprises the steps of:
and controlling the first die and the second die to separate the material belt according to a separation sequence O1, so that the material part is subjected to the acting force of the first elastic part, passes through the material belt and is separated from the material belt again.
