[0013] Compared with the prior art, the present invention has the following advantages: 1. The steel is intermittently transported to the left, and the hydraulic cylinder is controlled to move the lifting seat, fixed column, sliding seat, punching head, flattening cylinder and pressing rod downward. The pressing rod presses the steel to prevent the steel from being displaced.

[0016] 4. The steel squeezes the limit end, causing the lifting rod to drop. When the punching hole of the steel is aligned with the limit end, the reset spring causes the lifting rod to rise, and the limit end passes through the punching hole of the steel. The limit end limits the steel to prevent the steel from shifting during the cutting process and improve the cutting accuracy. After the cutting is completed, the triangular block squeezes the contact end to cause the lifting rod to drop, and the limit end leaves the punching hole of the steel.

[0017] 5. By rotating the screw, the translation block, support plate, front side plate, roller, connecting rod, rotating rod 1 and rack 2 are moved forward.

The left side of the mounting frame 101 is fixedly connected to the second mounting frame 111, and the belt conveyor 112 is installed on the second mounting frame 111. The belt conveyor 112 is a prior art. The belt conveyor 112 includes two conveyor belts arranged at intervals. Two front-to-back symmetrical guide rods 113 are connected to the upper part of the second mounting frame 111. Two sliding guide rails 114 with opposite sliding directions are slidably connected between the two guide rods 113. The guide rails 114 are each provided with a slider 115 that slides back and forth, and the sliding guide rails 114 are each installed with a linear motor for driving the slider 115 to slide, and the slider 115 is each installed with a laser cutting head 116; the cutting mechanism also includes an electric push rod 117, a moving block 118 and a second rotating rod 119, the rear part of the second mounting frame 111 is bolted with the electric push rod 117, the telescopic rod of the electric push rod 117 is connected to the moving block 118, and the moving block 118 is rotatably connected to the middle part of the two sliding guide rails 114 by the second rotating rod 119; the cutting mechanism also includes a material guide plate 110, and the lower left side of the second mounting frame 111 is fixedly connected to the inclined material guide plate 110.

[0033] refer to Figure 8 and Figure 9 The automated manufacturing equipment for motor punching sheets also includes a lifting rod 121 and a triangular block 124. A lifting rod 121 that slides up and down is provided at the lower part of the second mounting frame 111. A return spring is connected between the lifting rod 121 and the second mounting frame 111. The front end of the lifting rod 121 has a limit end 122 with an inclined surface. The limit end 122 extends from between the two spaced conveyor belts. The rear end of the lifting rod 121 has a contact end 123. The right slider 115 is connected to a triangular block 124. When the triangular block 124 moves backward, the triangular block 124 will contact the contact end 123 to squeeze the lifting rod 121 down.

[0034] In this embodiment, the automated manufacturing equipment for motor punching sheets can be specifically used to manufacture motor punching sheets. The steel 60 is intermittently transported to the left by the external conveying equipment. The steel 60 passes through the placement plate 2, the support plate 105 and the belt conveyor 112 from right to left in turn, and the hydraulic cylinder is controlled to drive the lifting seat 3 to descend. The lifting seat 3 drives the fixed column 4, the sliding seat 5, the rack 1 51, the connecting block 52, the small gear 53, the large gear 54, the rack 2 55, the punching head 6, the hinged rod 7, the push cylinder 8, the connecting column 81 and the pressing rod 82 to move downward together. As the rack 2 55 descends, the rotating rod 1 58 will rotate, and the roller 57 will roll to the left in the long hole 59. When the pressing rod 82 contacts the surface of the steel 60, the pressing rod 82 stops moving downward. The pressing rod 82 presses the steel 60 to prevent the steel 60 from moving. When the flattening cylinder 8 contacts the surface of the steel 60, the flattening cylinder 8 stops moving downward, and the lifting seat 3, sliding seat 5, rack 1 51, connecting block 52, small gear 53, large gear 54, rack 2 55, punching head 6 and connecting column 81 continue to descend. The compression spring is compressed, and the descending lifting seat 3 drives the hinge rod 7 to rotate clockwise with the rotating shaft 70 as the axis. The elastic member 9 is deformed. Under the action of the elastic member 9, the flattening cylinder 8 rolls on the surface of the steel 60, and the flattening cylinder 8 flattens the steel 60. The punching head 6 that continues to descend punches the steel 60. During the stamping process, the flatness of the steel 60 is improved with the cooperation of the flattening cylinder 8 and the pressing rod 82, thereby improving the stamping effect.

[0035] Then control the hydraulic cylinder to drive the lifting seat 3 to rise and reset, driving the fixed column 4, sliding seat 5, rack 1 51, connecting block 52, small gear 53, large gear 54, rack 2 55, punching head 6, hinged rod 7, flattening cylinder 8, connecting column 81 and pressing rod 82 to rise and reset. The pressing rod 82 and the flattening cylinder 8 are separated from the steel 60, the compression spring and elastic member 9 are restored, and the hinged rod 7 rotates counterclockwise around the rotating shaft 70 as the axis to reset.

[0036] The steel 60 is transported further to the left, the rear side plate 104 contacts the rear side of the steel 60, and the front side plate 106 contacts the front side of the steel 60, thereby limiting the steel 60 in the front and rear directions through the rear side plate 104 and the front side plate 106, and controlling the linear drive to drive the lifting column 102 to descend, driving the positioning pin 103 to descend, and the positioning pin 103 presses the steel 60, and the positioning pin 103 prevents the steel 60 from moving during the stamping process, and controlling the linear motor to drive the two sliders 115 to move backward, driving the laser cutting head 116 to move backward, and at the same time controlling the two laser cutting heads 116 to cut the steel 60, and then controlling the belt conveyor 112 to transport the cut steel forward, and the waste generated by the cutting falls and is discharged along the guide plate 110.

[0037] When the cutting width needs to be adjusted, the electric push rod 117 is controlled to drive the moving block 118 to translate in the front-to-back direction, and the two sliding guide rails 114 are driven to move away from or closer to each other in the left-to-right direction under the transmission of the rotating rod 119. The slider 115 and the laser cutting head 116 move in the left-to-right direction along with the sliding guide rail 114, so that the distance between the two laser cutting heads 116 in the left-to-right direction can be adjusted.

[0038] When the steel 60 moving to the left contacts the limit end 122, the steel 60 squeezes the limit end 122 under the action of gravity, causing the lifting rod 121 to descend and the return spring to deform. When the punching hole of the steel 60 is aligned with the limit end 122, the return spring recovers, causing the lifting rod 121 to rise and reset, and the limit end 122 passes through the punching hole of the steel 60, thereby limiting the steel 60 through the limit end 122, preventing the steel 60 from shifting during the cutting process and improving the cutting accuracy; the backward sliding block 115 drives the triangular block 124 to move backward. When the cutting is completed, the triangular block 124 will contact the contact end 123. The triangular block 124 squeezes the contact end 123 through the inclined surface, causing the lifting rod 121 to descend, the return spring deforms, and the limit end 122 leaves the punching hole of the steel 60. The belt conveyor 112 can transport the cut steel forward.

[0039] When a steel material 60 with a larger width needs to be stamped, the screw 108 is manually rotated, and the translation block 107 slides forward under the action of the threaded connection, driving the support plate 105 and the front side plate 106 to move forward, so that the distance between the front side plate 106 and the rear side plate 104 adapts to the width of the steel material 60. At the same time, the front side plate 106 drives the roller 57, the connecting rod 56, the rotating rod 1 58 and the rack 2 55 to move forward. Under the meshing action, the rack 2 55 rotates the large gear 54, and the large gear 54 drives The small gear 53 rotates, and the rotating small gear 53 causes the rack 1 51 to move forward, and the sliding seat 5 and the punch head 6 move forward with the rack 1 51. Since the number of teeth of the small gear 53 is half of the number of teeth of the large gear 54, the forward movement distance of the rack 1 51 is half of the forward movement distance of the rack 2 55, and the forward movement distance of the punch head 6 is half of the forward movement distance of the front side plate 106, so that the position of the punch head 6 can be synchronously moved to the center of the steel 60. The adjustment is automated and highly synchronous, so that steel 60 with a larger width can be punched.
