[0021] like Figure 4-Figure 6 As shown, the flattening assembly includes a flattening plate 33 and an electric push rod 34; two front and rear flattening plates 33 are slidably connected to the fixed frame 13; two front and rear electric push rods 34 are installed on the fixed frame 13; the telescopic ends of the two electric push rods 34 are respectively fixed to a corresponding flattening plate 33; the four flattening plates 33 are all set to a wedge structure on one side facing the support column 3.

[0022] The punching working steps of the metal material processing punching machine for automatically collecting waste materials of the present invention are as follows.

[0023] The electric conveying roller group 15 conveys the metal sheet 5 between the punching head 21 and the support column 3 along the punching table 14. During this process, when the end of the metal sheet 5 moves between the two first punching knives 25 and the second punching knives 26, the electric conveying roller group 15 stops running, and the punching machine 2 first controls the punching head 21 to drive the telescopic punch 22, the hollow punching plate 24 and the cutting knife group to move downward, such as Figure 7 As shown, two first punching knives 25 cooperate with the punching table 14 to punch out two front and rear side cutting groove structures 50 in the left area of ​​the end of the metal sheet 5.

[0024] After the punching machine 2 first controls the punching head 21 to drive the telescopic punching head 22, the hollow punching plate 24 and the cutting knife group to move upward and reset, the electric conveying roller group 15 continues to convey the end of the metal sheet 5 to between the punching head 21 and the support column 3 along the punching table 14, and then the punching machine 2 first controls the punching head 21 to drive the telescopic punching head 22, the hollow punching plate 24 and the cutting knife group to move downward. At this time, the punching head 21 first drives the telescopic punching head 22 to press the end of the metal sheet 5 down on the support column 3, so that the telescopic punching head 22 is blocked by the support column 3 and no longer moves downward. At the same time, the punching head 21 drives the second punching knife 26 to cooperate with the punching table 14 to cut off the connection area of ​​the two side cutting groove structures 50 on the left side of the metal sheet 5, so that the end of the metal sheet 5 is cut out of a single piece of metal onto the support column 3, and the new end of the metal sheet 5 is located between the two first punching knives 25 Between the second punching knife 26, the two first punching knives 25 punch out two front and rear side cutting groove structures 50 in the left area of ​​the new end of the metal sheet 5, and then the punching head 21 that continues to move downward drives the hollow punching plate 24 to push the metal single sheet on the support column 3 to punch downward, and at the same time, the punching head 21 drives the return spring 23 to compress downward, so that the middle part of the metal single sheet is supported by the support column 3 and the metal material of the required shape is punched out, and the part of the metal single sheet that is not supported by the support column 3 is punched downward by the hollow punching plate 24 to obtain the outer ring waste, and when the hollow punching plate 24 continues to push the outer ring waste downward to pass through the front and rear third punching knives 31, the two third punching knives 31 respectively cut off the front connecting area and the rear connecting area of ​​the outer ring waste, so that the outer ring waste is cut to form two left and right waste sheets 51.

[0025] Afterwards, the punching head 21 drives the hollow punching plate 24 to continue to push the left and right waste pieces 51 to move downward, and at the same time, the electric push rods 34 on the front and rear sides respectively pull the corresponding flat pressing plates 33 away from each other in the front and rear directions, so that the flat pressing plates 33 will not block the left and right waste pieces 51 below, so that the hollow punching plate 24 can smoothly push the left and right waste pieces 51 downward onto the vertical carrying plates 45 in the two limiting rods 44, and the hollow punching plate 24 pushes the waste piece 51 to drive the vertical carrying plate 45 to move downward along the limiting rod 44, and at the same time, the vertical carrying plate 45 drives the supporting compression spring 46 to compress downward until the upper surface of the waste piece 51 is flush with the lower surface of the flat pressing plate 33. After that, the electric push rods 34 on the front and rear sides respectively push the corresponding flat pressing plates 33 to move and reset in the direction between the hollow punching plate 24 and the waste sheet 51. After the flat pressing plate 33 is inserted between the hollow punching plate 24 and the waste sheet 51 through the wedge structure, the punching machine 2 first controls the punching head 21 to drive the telescopic punching head 22, the hollow punching plate 24 and the cutting knife group to move upward and reset. At the same time, the compressed reset spring 23 pushes the punching head 21 to pop up downward. At this time, the flat pressing plate 33 presses the waste sheet 51 downward tightly against the vertical carrier plate 45, and the vertical carrier plate 45 is blocked by the flat pressing plate 33. The compressed supporting compression spring 46 will not bounce the vertical carrier plate 45 upward, thereby completing the loading of the waste sheet 51.

[0026] After that, continue to follow the above steps to punch out metal materials of the required shape at various parts of the metal sheet 5, and use the same steps to successively load the waste sheets 51 on the left and right sides onto the vertical carrier plates 45 in the left and right limit rods 44, and use the flat pressing plate 33 to press the waste sheets 51 stacked on the vertical carrier plates 45 together, so as to automatically complete the orderly collection and stacking of the waste sheets 51.

[0027] When the operator observes that the waste pieces 51 in the limit rod 44 are filled, the operator shuts down the punching machine 2 and the punching table 14 to put them in a resting state. At this time, the vertical carrier plate 45 is pressed down by the stacked waste pieces 51 to be close to the support block 43. Thereafter, the two movable carrier mechanisms respectively drive the two vertical carrier plates 45 and the filled waste pieces 51 to move away from each other in the left and right directions, respectively, so that the waste pieces 51 leave the support column 3, and the flat pressing plate 33 keeps pressing the first waste piece 51 above the vertical carrier plate 45, so that the vertical carrier plate 45 remains in a downward pressed state. The operator uses the cable tie machine handheld to tie two circles of cable tie rings 52 between all the waste pieces 51 stacked on the same vertical carrier plate 45 using the cable ties in the cable tie machine, thereby completing the bundling of all the stacked waste pieces 51, so that the operator can take out all the bundled waste pieces 51 from the limiting rod 44 at one time, and after all the waste pieces 51 are bundled together, it is convenient for them to be carried and stacked, and the stacked waste pieces 51 are cut into fragments without hollow structures, so that the stacked waste pieces 51 can be placed tightly, greatly reducing the occupation of site space.

[0028] Example 2 On the basis of Example 1, Figure 1-Figure 6 As shown, a recessed structure 4501 is respectively provided on the front side and the rear side of the upper surface of the two vertical carrier plates 45 of this embodiment; a punching protrusion 32 is respectively fixedly connected to the left side and the right side of the two third punching knives 31 .

[0029] When the hollow stamping plate 24 pushes the outer ring waste of the metal sheet 5 downward through the third punching knife 31, the third punching knife 31 cuts the outer ring waste of the metal sheet 5 into two left and right waste sheets 51. At the same time, the opposite sides of the two waste sheets 51 will pass through four punching protrusions 32, and the four punching protrusions 32 will respectively punch out two groove structures 510 on the opposite sides of the two waste sheets 51.

[0030] When the operator observes that the waste pieces 51 in the limit rod 44 are filled, the operator shuts down the punching machine 2 and the punching table 14 to put them in a rest state. At this time, the vertical carrier plate 45 is pressed down by the stacked waste pieces 51 to be close to the support block 43, and the groove structures 510 of all the waste pieces 51 stacked on the same vertical carrier plate 45 are aligned in the vertical direction. Thereafter, the two moving platform mechanisms respectively drive the two vertical carrier plates 45 and the filled waste pieces 51 to move away from each other in the left and right directions, respectively, so that the waste pieces 51 leave the support column 3, and the flat pressing plate 33 keeps pressing the first waste piece 51 above the vertical carrier plate 45, so that The vertical carrier plate 45 is kept in a downward pressed state, and then the operator holds the cable tie machine and pulls out the cable tie in the cable tie machine, and passes the pulled cable tie end through the lower surface of the first waste piece 51 on the bottom layer through the recessed structure 4501 of the vertical carrier plate 45, and then pulls the cable tie end upward and inserts it into the groove structure 510 of each waste piece 51, and then passes the cable tie end around the upper surface of the first waste piece 51 on the top layer and pulls it back into the cable tie machine, so that the cable tie end is allowed to circle around all the stacked waste pieces 51 and return to the cable tie machine, and finally the cable tie machine tightens the circle of cable tie wrapped around the stacked waste pieces 51 and melts it to form a cable tie loop 52, as shown in FIG. Fig. 9 As shown, a tie ring 52 is respectively tied in the front groove structure 510 and the rear groove structure 510 of all the stacked waste pieces 51 according to the same steps to complete the bundling of all the waste pieces 51 on the vertical carrier plate 45, so that the operator can take out all the bundled waste pieces 51 from the limiting rod 44 at one time, and after all the waste pieces 51 are bundled together, they are convenient for transportation and stacking.

[0031] Example 3 On the basis of Example 2, Figure 1-Figure 6As shown, the mobile platform mechanism of this embodiment includes an electric bidirectional threaded screw 41, a transverse moving slider 42, an electric slider 47 and an insertion rod 48; two front and rear electric bidirectional threaded screws 41 are rotatably connected to the base frame 11; two transverse moving sliders 42 that are symmetrical to each other are slidably connected to the base frame 11; the left side threads of the two electric bidirectional threaded screws 41 are jointly screwed to the left side transverse moving slider 42; the right side threads of the two electric bidirectional threaded screws 41 are jointly screwed to the right side transverse moving slider 42; two support blocks 43 are respectively slidably connected to the two transverse moving sliders 42; each of the two transverse moving sliders 42 slides An electric slider 47 is connected; the two electric sliders 47 are respectively fixed to the two support blocks 43; the front sides of the two transverse movable sliders 42 are each fixed to an insertion rod 48; the two vertical carrier plates 45 are respectively provided with a socket structure 4502 corresponding to the two insertion rods 48; the parts where the two support blocks 43 are connected to the support compression springs 46 are installed with pressure sensors, and one end of the support compression spring 46 connected to the support block 43 is fixed to the sensing component of the pressure sensor, and the pressure sensor on the support block 43 identifies the compression elastic force from the support compression spring 46, determines the compression degree of the support compression spring 46, and thereby knows the current filling amount of the waste sheet 51 in the limit rod 44.

[0032] When the pressure sensor on the support block 43 identifies that the waste pieces 51 in the limit rod 44 are full by judging the compression degree of the support pressure spring 46, the pressure sensor on the support block 43 feeds back to the control cabinet 12 through the circuit system to automatically shut down the punching machine 2 and the punching table 14, so that the punching machine 2 and the punching table 14 are in a rest state. At this time, the vertical carrier 45 is pressed down by the stacked waste pieces 51 to be close to the support block 43, and the socket structure 4502 of the vertical carrier 45 is aligned with the insertion rod 48 on the same side at the same height. After that, the two electric bidirectional threaded screws 41 synchronously drive the left and right horizontal moving sliders 42 to move away from each other in the left and right directions respectively, and the flat pressure plate 33 keeps pressing the first waste piece 51 above the vertical carrier 45, so that the vertical carrier 45 remains in a downward pressed state to prevent the compressed support pressure spring 46 from pushing the vertical carrier 45 to bounce the waste piece 51 upward. Figure 8 As shown, until the waste pieces 51 on the two vertical carriers 45 are away from the support column 3, the electric slider 47 drives the support block 43 and the vertical carrier 45 to move forward, and at the same time, the insertion rod 48 is inserted into the vertical carrier 45. The insertion rod 48 replaces the flat pressing plate 33 to keep the vertical carrier 45 in a downward pressed state, allowing the vertical carrier 45 to drive the stacked waste pieces 51 to move forward, so that the operator can bundle and take out the stacked waste pieces 51.
