[0026] Through the cooperation of the conveying device 5 and the laminating device 6, the processing device can be adjusted according to the three-phase sheets of different specifications and sizes, thereby improving the applicability of the processing device. At the same time, the three-phase sheets after stamping and cutting are transported and preliminarily positioned by the conveying device 5, and then the three-phase sheets are accurately positioned by the laminating device 6, so that multiple three-phase sheets are stacked on each other to form an iron core, and the iron core is loaded on the forming mold 7, thereby achieving the effect of automatically stacking silicon steel sheets to prepare the iron core, avoiding the problems of high labor intensity and low efficiency of the previous manual or semi-automatic laminating method, greatly improving the processing efficiency and reducing the labor intensity.

[0027] The conveying device 5 is placed at an angle, and its end close to the discharge port of the stamping equipment 3 is the highest point. The conveying device 5 includes a V-shaped spring piece 8, the V-shaped spring piece 8 is placed with its opening facing upward, and its two side walls at the top are respectively fixedly connected with a bottom rod 9, and the top wall of the bottom rod 9 is fixedly connected with a side plate 10.

The adjusting device includes a threaded rod 12, the rod bodies of the threaded rod 12 are respectively penetrated and slidably connected to the middle parts of the rod bodies of the two bottom rods 9, the threaded ends of the threaded rod 12 are threadedly connected with a nut 13, one side of the nut 13 is rotatably connected to one of the side walls of the bottom rod 9, the outer side wall of the nut 13 is sleeved and fixedly connected with a gear 14, the tooth end of the gear 14 is meshedly connected with a gear 2 15, the rotating shaft end of the gear 2 15 is rotatably connected to the side wall of the bottom rod 9, and the gear 2 15 is driven to rotate by a motor 16.

[0028] The specifications of the silicon steel three-phase sheet are pre-processed according to the needs, and the nut 13 is driven to rotate by the motor 16, and the elastic force of the V-shaped spring 8 is cooperated to adjust the distance between the two bottom rods 9, so that the slide rail structure formed by the two side plates 10 corresponds to the two grooves of the three-phase sheet, and a certain margin is left between the two, so that the three-phase sheet can slide on the slide rail structure formed by the two side plates 10; the silicon steel sheets on the reel device 4 are quantitatively input into the stamping device 3 under the action of the feeding device 2 to be stamped and cut to form a sheet-shaped three-phase sheet. The stamped and cut three-phase sheet is pushed by the subsequent silicon steel sheets and falls onto the conveying device 5. Because it is placed at an angle, the three-phase sheet slides to the stacking device 6 under the action of gravity.

[0029] The stacking device 6 includes a bottom rod 17, one end of which is rotatably connected to the lowest end of the bottom rod 19, and a side panel 18 is fixedly connected to the top of the bottom rod 17. An expandable expansion device is provided on the outer side wall of the top of the side panel 18. When the expansion device is closed with the side panel 18, a slide rail structure corresponding to the side panel 10 is formed. A gantry 19 is provided on the outside of the slide rail structure, and an electric push rod 20 is provided at the center of the upper crossbeam of the gantry 19. The output end of the electric push rod 20 is rotatably connected to the rotating shaft at the top of the stacking plate 21. A slide rod 22 is symmetrically penetrated and slidably connected to the middle part of the rod body of the two bottom rods 17. The slide rod 22 is connected to the workbench 1 through an elastic telescopic rod 23, so that the side panel 18 is flush with the side panel 10. The expansion device includes a support plate 24, a side wall of the support plate 24 is fixedly connected with a sliding column 25, the sliding column 25 is inserted into and slidably connected in the plate body of the side plate 18, a spring 26 is sleeved on the outer wall of the sliding column 25, an electromagnetic adsorption module 27 is embedded in and fixedly connected in the plate body of the side plate 18, an iron plate 28 corresponding to the electromagnetic adsorption module 27 is embedded in and fixedly connected in the plate body of the support plate 24, when the electromagnetic adsorption module 27 is powered on, the iron plate 28 is adsorbed and the support plate 24 is fitted with the side plate 18, when the electromagnetic adsorption module 27 is powered off, the force of adsorbing the iron plate 28 is eliminated, and the support plate 24 is separated from the side plate 18 under the action of the spring 26. The side plate 218 is provided with a baffle plate 29 at one end away from the conveying device 5. The baffle plate 29 is connected to the side plate 218 through a torsion spring. In normal state, the baffle plate 29 is perpendicular to the upper surface of the side plate 218 to prevent the three-phase sheet on the side plate 218 from sliding off. When the force on the baffle plate 29 exceeds the set value of the torsion spring, the baffle plate 29 is parallel to the side plate 218, so that the three-phase sheet on the side plate 218 passes over the baffle plate 29. The stacking plate 21 includes an adsorption plate 2101 and a pressing plate 2102, one end of which is perpendicular to each other and fixedly connected. The adsorption plate 2101 is provided with an electromagnetic adsorption module 2103. When it is powered on, the adsorption plate 2101 generates magnetic attraction to the multiple three-phase sheets.

[0030] The bottom bar 2 17 is connected to the bottom bar 1 9 so that it changes synchronously with the adjustment of the bottom bar 1 9, so that the two side plates 2 18 are flush with the two side plates 10 respectively, and the three-phase sheet can slide onto the side plate 2 18 and finally be blocked by the baffle 29. When the number of three-phase sheets on the side plate 2 18 reaches the preset requirement, the stamping is stopped and the electromagnetic adsorption module 1 27 is powered off. Then, under the action of the spring 26, the support plate 24 is separated from the side plate 2 18, so that the margin between the three-phase sheet and the side plate 2 18 is filled, and then the three-phase sheet is aligned and positioned in one direction. At this time, the electric push rod 20 drives the stacking plate 21 to move downward. The pressing plate 2102 first contacts the top of the three-phase photo, and then the adsorption plate 2101 contacts the side wall of the outermost three-phase photo and continues to move downward. The pressing plate 2102 presses the top of the three-phase photo, so that the three-phase photo is aligned and positioned in another direction. At the same time, the electromagnetic adsorption module 2 2103 in the adsorption plate 2101 is started to adsorb all the three-phase photos. The electric push rod 20 continues to move downward, causing the elastic telescopic rod 23 to contract, and finally the stacked three-phase photos are in a vertical state. Under the action of the downward pressure, the baffle 29 is parallel to the side plate 2 18, so that the stacked three-phase photos are moved out of the stacking device 6.

[0031] The forming mold 7 includes a base 701 , which is disposed below the lamination device 6 . A plurality of limiting grooves 702 of different sizes are layered in the base 701 , and each limiting groove 702 corresponds to an iron core base 703 of a certain specification.

[0032] Under the action of electromagnetic adsorption module 2103, the stacked three-phase sheets are adsorbed and aligned, and continue to descend so that the holes on the three-phase sheets are inserted into the corresponding limit rods on the core base 703 until all the three-phase sheets are completely inserted, that is, the step of automatically stacking the three-phase sheets to form the core is completed. The setting of multiple limit slots 702 of different sizes allows the base 701 to be used to position core bases 703 of different specifications.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
