[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that all components in the technical solution of this application require the necessary additional facilities of water supply, oil supply, electricity supply and gas supply to be driven and / or controlled. If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.

[0031] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Depend on Figure 1-2 As shown, a motor rotor sheet blanking and feeding device is fixedly mounted on a punching machine and is adapted to a die fixedly mounted on the punching machine, comprising:

[0033] The rotary feeder is used to pick up sheet materials and rotor sheets, and includes a rocker arm and a first driver, which are transmission-connected to the rocker arm and the driver, and the first driver is transmission-connected to the punching machine, wherein the sheet material is circular and has a positioning hole in the center, so as to facilitate punching of the sleeve hole on the edge of the sheet material.

[0034] The material collecting assembly is used to collect the stamped rotor sheets, and includes a material collector, a first base 18 and a material stopper. The material collector is fixedly connected to the first base 18, the bottom end of the material stopper is fixedly connected to the first base 18, and the top end of the material stopper is adapted to the rocker arm.

[0035] The material pushing component is used to push the sheet material, and the material pushing component is adapted to the rocker arm;

[0036] The material stripping assembly is used to remove the sheet material picked up by the rocker arm, and comprises a material stripper, a second base and a second driver. The material stripper is transmission-connected to the second driver, and the second driver is respectively hinged to the second base and the punching machine.

[0037] Furthermore, the stamping machine includes a main motor, a flywheel, a clutch, a gear, a crankshaft, a connecting rod, a mounting body, an upper slider and a lower slider (the attached figure only shows the key components). It is one of the important machine tools used to form metal sheets. Its structure is existing technology and will not be repeated here.

[0038] Furthermore, the mold includes an upper mold and a lower mold, and the lower mold positions the sheet material through the center hole of the sheet material and its own positioning pins.

[0039] To further optimize the solution, Figure 3-4As shown, the rocker arm includes a crossbeam 1, the center of the crossbeam 1 is connected to the first driver in a transmission manner, and the two ends of the crossbeam 1 are respectively provided with mounting grooves 2, and a magnet 3 is slidably connected in the mounting groove 2, and the bottom surface of the magnet 3 is in sliding contact with an isolation plate 4, and the magnet 3 is a strong magnet, which can penetrate the isolation plate 4 to adsorb the sheet material to the bottom surface of the isolation plate 4, and the isolation plate 4 can facilitate the ejection assembly to push the sheet material down into the mold to prevent the magnet 3 from having too large an adsorption force, resulting in the inability to remove the material. The bottom surface of the isolation plate 4 is detachably connected to the sheet material, and the isolation plate 4 is fixedly connected to the bottom surface of the crossbeam 1, and the center of the magnet 3 is fixedly connected to a rotating shaft 5, and the top of the rotating shaft 5 is rotatably connected to a connecting rod 6, and one end of the connecting rod 6 is rotatably connected to an eccentric disk 7, and the eccentric disk 7 is connected to a first motor 8 in a transmission manner, and the first motor 8 is fixedly connected to the top surface of the crossbeam 1; the two ends of the top surface of the crossbeam 1 are respectively fixedly connected to magnetic support blocks 9, and the top surface of the support block 9 is used to support the rotor sheet after punching. The eccentric disk 7 is driven to rotate by the first motor 8, and a connecting rod 6 is fixedly connected to the top edge of the eccentric disk 7. One ends of the two connecting rods 6 are hinged to each other through a hinge seat, and the hinge seat is rotatably connected to the connecting rod 6. When the connecting rod 6 is driven to rotate by the eccentric disk 7, the two connecting rods 6 can be driven to move at the same time. The connecting rod 6 drives the rotating shaft 5 and the magnet 3 to slide in the mounting groove 2, so that when the magnet 3 is on the bottom surface of the isolation plate 4, the sheet material can be adsorbed on the isolation plate 4. When the magnet 3 is pushed to the other end of the isolation plate 4, the attraction of the magnet 3 to the sheet material can be reduced, so that it will fall due to its own gravity and enter the mold.

[0040] Furthermore, the time taken by the first motor 8 to rotate one circle is four times that of the driving shaft 11, so that the magnets 3 at both ends of the beam 1 can be synchronized with the stamping action of the mold to achieve linkage feeding. At the same time, the first motor 8 is a servo motor, and its start timing can be controlled by a PLC controller, and the PLC controller is connected to the control system of the stamping machine, so that the first motor 8 and the stamping machine can achieve synchronous operation.

[0041] Furthermore, an isolation groove adapted to the sheet material is provided on the bottom surface of the isolation plate 4. After the sheet material is adsorbed onto the isolation plate 4, it will contact the isolation plate 4 during the movement of the magnet 3, and then fall off the isolation plate 4 after the magnetic force of the magnet 3 disappears.

[0042] A further optimized solution is that the first driver includes a mounting base 10, the mounting base 10 is fixedly connected to the table top of the punching machine, the side wall of the mounting base 10 passes through and is rotatably connected with a driving shaft 11, one end of the driving shaft 11 is fixedly connected with a first sprocket 12, the first sprocket 12 is connected to a second sprocket 14 through a chain 13, the second sprocket 14 is connected to one end of the crankshaft of the punching machine, and the chain 13 is respectively connected to the first sprocket 12 and the second sprocket 14, so that the first sprocket 12 and the second sprocket 14 can rotate synchronously without difference, thereby avoiding the angular difference caused by slipping of the belt drive. One end of the driving shaft 11 is fixedly connected to the first bevel gear 15, the first bevel gear 15 is meshingly connected to the second bevel gear 16, the second bevel gear 16 is fixedly connected to the vertical rod 17, the vertical rod 17 is fixedly connected to the cross beam 1, the vertical rod 17 is rotatably connected to the mounting base 10, the first bevel gear 15 and the second bevel gear 16 have the same diameter, so that the first sprocket 12 can synchronously drive the driving shaft 11, the first bevel gear 15, the second bevel gear 16 and the vertical rod 17 to rotate one circle when one rotation is made, so as to keep synchronization with the stamping action of the stamping.

[0043] Furthermore, the second sprocket 14 is fixedly connected to one end of the crankshaft of the punching machine. When the crankshaft is driven by the main motor to rotate, it can drive the second sprocket 14 to rotate. At the same time, the chain 13 will drive the first sprocket 12 to rotate under the drive of the second sprocket 14. The rotation of the first sprocket 12 can drive the drive shaft 11, the first bevel gear 15, the second bevel gear 16 and the vertical rod 17 to rotate, thereby realizing the rotation of the beam 1. At this time, the sheet materials or rotor sheets at both ends of the beam 1 can be driven for loading or unloading.

[0044] According to a further optimized solution, the diameter of the first sprocket 12 is four times that of the second sprocket 14, so that the punching machine can move up and down twice, and the crossbeam 1 can rotate one circle to complete two loading and unloading operations.

[0045] To further optimize the solution, Figure 5As shown, the material collector includes a slide plate 19, which is fixedly connected to the first base 18; a slide groove 20 is provided on the top surface of the slide plate 19, and the slide groove 20 is adapted to and in sliding contact with the rotor sheet. The slide plate 19 is arranged obliquely, and the top end of the slide plate 19 is arranged directly below the rotating support block 9, so that the rotor sheet can slide down smoothly along the slide groove 20. One end of the slide plate 19 is adapted to one end of the beam 1, and the other end surface of the slide plate 19 is rotatably connected to two buckets 21, which are symmetrical and close to each other. The ends of the two buckets 21 that are away from each other are hinged to the other end surface of the slide plate 19 through a hinge. Further, the hinge is a torque hinge, which can restore the closed state by itself after opening. It is a prior art and will not be described in detail here. The bottom surface of the bucket 21 is fixedly connected with a push column 22, and a push plate 23 is set against the push column 22. One end of the push plate 23 is transmission-connected with a telescopic member 24, and the telescopic member 24 is fixedly connected to the bottom surface of the slide plate 19. A material collection assembly is set just below the two buckets 21. By extending the telescopic member 24, the push plate 23 can push the push column 22 to slide to one side, and then the buckets 21 that fit each other are expanded, and the rotor sheet that slides into the bucket 21 can fall into the material collection assembly below the bucket 21.

[0046] Furthermore, the telescopic member 24 is a hydraulic cylinder or an electric cylinder, and preferably an electric cylinder is used, which is convenient for driving and controlling it using a PLC controller and reduces the control difficulty. This is a prior art and will not be described in detail here.

[0047] Further optimization scheme, the material stopper includes two material stopper rods 25, the top ends of the two material stopper rods 25 are fixedly connected with a fixing plate 26, and the fixing plate 26 is fixedly connected to the top surface of the first base 18; the material stopper rods 25 conflict with the side of the rotor sheet; the bottom surface of the material stopper rods 25 is higher than the top surface of the cross beam 1, so as to avoid interference between the cross beam 1 and the material stopper rods 25 when the cross beam 1 rotates. The distance between the two material stopper rods 25 is greater than the length of the support block 9, so that when the cross beam 1 drives the support block 9 to rotate, it can pass through the two material stopper rods 25, and the rotor sheet placed on the top surface of the support block 9 can be pushed down by the material stopper rods 25 and fall into the chute 20.

[0048] According to a further optimized solution, the material collection assembly includes a pin 27 and a tray 28. The pin 27 is fixedly installed at the center of the tray 28. The pin 27 is adapted to and in sliding contact with the center hole of the sheet material, so as to connect several sheets in series. A guide rod 29 is fixedly connected to the top surface of the tray 28, and the guide rod 29 is adapted to and slidably contacts the edge notch of the rotor sheet. A ball 30 is embedded in and rotatably connected to the top of the guide rod 29. When the rotor sheet is opened by the opened bucket 21, the rotor sheet will fall through the center hole of the rotor sheet and the adaptation of the ejector pin 27, and the rotor sheets will be connected in series. In order to align the edge notches of all the rotor sheets and achieve convenient subsequent processing, in order to prevent the rotor sheets from bouncing on the ejector pin 27 during the falling process, which makes it impossible to stack them together smoothly, the rotor sheets will come into contact with the ball 30 when the rotor sheets bounce. Because the ball 30 is rotatably connected to the guide rod 29, the rotor sheets will slide relative to the ball 30 due to the inclination until the ball 30 enters the notch at the edge of the rotor sheet, so that all the rotor sheets that enter the ejector pin 27 can be aligned and stacked up and down.

[0049] A further optimized solution is that the material stripper includes a material stripper plate 31, one end of which is rotatably connected to a material stripper wheel 32, and the material stripper wheel 32 is in sliding connection and contact with the top surface of the sheet material entering the mold; the side surface of the material stripper plate 31 is transmission connected to the second driver. When one end of the beam 1 carries the sheet material into the mold, the magnetic force of the magnet 3 gradually weakens, and the sheet material contacts the material stripper wheel 32, and the bottom end of the material stripper wheel 32 is lower than the horizontal height of the sheet material, one end of the sheet material can be pressed down to fall off the isolation plate 4, and enter the positioning pin of the lower mold to realize self-positioning of the sheet material, which is convenient for the upper mold to perform blanking.

[0050] Further optimization scheme, the second driver includes a drive frame 33, a first vertical rod 34 and a second vertical rod 35, the drive frame 33 is fixedly connected to the lower slider of the punching machine, one end of the first vertical rod 34 and one end of the second vertical rod 35 are respectively hinged to the drive frame 33, the other end of the first vertical rod 34 and the other end of the second vertical rod 35 are respectively hinged to the side of the stripper plate 31, the middle of the first vertical rod 34 is hinged with a third vertical rod 36, one end of the third vertical rod 36 is hinged to the upper slider of the punching machine. The downward movement of the upper slider of the punching machine will push the third vertical rod 36 to move, the third vertical rod 36 pushes the first vertical rod 34 to move, and then pushes the stripper plate 31 to move toward the side away from the punching machine, and finally drives the stripper to exit the mold to avoid interference with the movement of the mold.

[0051] Furthermore, a plurality of through holes are opened on the side of the first vertical rod 34, and bolts are rotatably connected in the through holes. The first vertical rod 34 is rotatably connected to the third vertical rod 36 through the through holes and the bolts. By adjusting the position of the rotational connection between the third vertical rod 36 and the first vertical rod 34, the force arm of the third vertical rod 36 driving the first vertical rod 34 can be adjusted, thereby adjusting the speed of the ejector exiting and entering the mold.

[0052] To further optimize the solution, Figure 6 As shown, the ejection assembly includes a barrel 37, a top plate 38 is provided on the bottom surface of the inner cavity of the barrel 37, a first screw 39 is fixedly connected to the center of the top plate 38, the bottom end of the first screw 39 passes through the bottom surface of the barrel 37 and is transmission-connected to a reducer 40, the reducer 40 is fixedly and transmission-connected to a second motor 41, and a first sliding guide plate 42 is fixedly connected to one side of the reducer 40; a screw ring 43 is fixedly connected to the bottom surface of the barrel 37, the screw ring 43 is sleeved on the outside of the first screw 39 and is threadedly connected to the first screw 39; the first screw 39 is hollow, and an oil cylinder 46 is fixedly connected to the bottom surface of the barrel 37, two sliding guide grooves 47 are provided on the inner cavity side wall of the oil cylinder 46, the first sliding guide plate 42 is slidably connected to the two sliding guide grooves 47, and the oil cylinder 46 is filled with lubricating oil; a plurality of hollow holes are respectively provided on the top plate 38 and the bottom surface of the inner cavity of the barrel 37. The second motor 41 drives the reducer 40 to accurately output and drive the first screw 39 to rotate a certain angle, so as to push all the sheets set in the barrel 37 to rise to a certain height, until the bottom surface of the sheet at the top is flush with the top surface of the barrel 37, thereby reducing the resistance of the magnet 3 to adsorb the sheet. When the beam 1 drives the isolation plate 4 to move to the top of the sheet, the sheet will be adsorbed to the isolation plate 4 due to the magnetic force of the magnet 3, so that the sheet can be picked up.

[0053] When the first screw 39 rotates, it will be screwed with the screw ring 43 to achieve the first screw 39 to move up a certain distance, thereby driving the reducer 40 and the second motor 41 to move up synchronously along the guide groove 47. At the same time, the rotation of the second motor 41 will drive the oil in the oil cylinder 46 to stir, and infiltrate the sheet material in the barrel 37. When the sheet material is being punched, the punching pressure can be reduced, and the heat can also be dissipated from the punching edge of the mold, thereby improving the molding quality and the life of the mold.

[0054] Furthermore, the reducer 40 can reduce the rotation speed of the second motor 41, increase the output torque, and facilitate the control of the output angle. The second motor 41 is a servo motor, which can accurately control the ejection height of the sheet metal under the PLC controller. This is a prior art and will not be described in detail here.

[0055] Furthermore, the oil can enter the barrel 37 through the hollow and hollow holes of the first screw 39 to achieve infiltration of the sheet material.

[0056] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
