Advantageously, the machine body box 11 is provided with a recovery cavity 59 positioned on the lower side of the discharge port 60, the recovery cavity 59 is opened upwards, and the recovery cavity 59 can be used for receiving the water flow flowing downwards, so that waste is prevented.

The alarm system of the stamping die comprises the following working procedures:

fixing the processing plate 16 on the upper side of the supporting push rod 15, starting the supporting push rod 15, pulling the processing plate 16 to move downwards, abutting the processing plate 16 against the detection box 30, driving the contraction box 24 to move downwards, compressing the supporting spring 23, driving the rotation shaft 22 to move downwards, driving the rotation shaft 22 to rotate through the screw transmission principle due to the action of the sliding pin 21 and the spiral chute 20, thereby driving the rotation disc 26 to rotate, driving the symmetrical detection boxes 30 to approach each other due to the action of the oval chute 27, compressing the processing plate 16 into the contraction groove 17 by the detection box 30 contracting into the transmission cavity 25, stably placing the processing plate 16 on the upper side of the supporting table 14, performing stamping processing on the processing plate 16 by using the processing press machine 13, and starting the supporting push rod 15 to push the processing plate 16 upwards after the processing plate 16 is processed, the contraction box 24 is popped up under the action of the supporting spring 23, each part is reset, the detection box 30 moves along the lower side end face of the processed plate 16, whether burrs are on the lower side end face of the processed plate 16 can be detected by the burr detector 32, if the burrs are on the lower side end face of the processed plate 16, the first push rod 33 and the driving motor 38 are started, after the first push rod 33 is started, the blocking plate 34 can be driven to slide upwards, the blocking plate 34 does not block the sliding plate 37, the sliding plate 37 can slide upwards under the action of the force storage spring 36, so that the second grinding disc 41 and the first grinding disc 45 are driven to be in contact with the surface of a workpiece to be processed, meanwhile, the driving motor 38 is started, the first transmission shaft 39 can be driven to rotate, the first straight gear 40 is driven to rotate, and the second straight gear 42 can be driven to rotate by itself while rotating around the first straight gear 40 by the planetary gear transmission principle, thereby driving the second transmission shaft 43 to rotate around the first transmission shaft 39 and simultaneously rotating itself, i.e. the first grinding disc 45 and the second grinding disc 41 rotate with the second transmission shaft 43 and the first transmission shaft 39 respectively, so that the first grinding disc 45 and the second grinding disc 41 can be used for grinding the burr parts on the workpiece, meanwhile, when the sliding plate 37 slides upwards, the vertical rack 48 can be driven to slide upwards, the third spur gear 50 can be driven to rotate by the meshing transmission principle, thereby the third transmission shaft 51 can be driven to rotate, the fourth transmission shaft 52 can be driven to rotate by the gear pair transmission principle, the fifth transmission shaft 53 can be driven to rotate by the belt transmission principle, thereby the cam 54 can be driven to rotate, the abutting plate 55 can be driven to slide left and right by the cam transmission principle, thereby the copper gong 57 can be knocked by the knocking hammer 56, and then the sound can be generated, reminding an operator that deburring work is being carried out;

whether foreign matters exist in the discharging hole 60 or not can be detected through the object sensor 76, for example, if an operator stretches a hand into the discharging hole 60, if the operator stretches the hand into the discharging hole 60 during working, the driving push rod 64 is started, the water pushing plate 65 can be driven to slide downwards, the driving rod 66 is driven to slide downwards, and the fixing plate 72 slides downwards along with the driving rod, due to the action of the horizontal sliding groove 73, the rotating shaft 71 can be driven to rotate around the sixth transmission shaft 69, namely, the reciprocating disc 70 rotates, so that the sixth transmission shaft 69 is driven to rotate, through the gear transmission principle, the seventh transmission shaft 74 can be driven to rotate, so that the fan blades 75 are driven to rotate, downward wind power can be generated, the wind power is blown to the alarm whistle 77, an alarm sound is given, the operator is reminded to retract the hand, and meanwhile, when the driving push rod 64 drives the water pushing plate 65 to move downwards, water in the water pushing plate 65 can be utilized to enable water in the water storage cavity 63 to flow into the discharging hole 60 through the lower opening of the water spraying pipeline 67 after passing through the pressure valve 68 And a protective water curtain is formed so as to warn an operator to retract hands.

It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
