Description

Technical Field

[0001] The utility model relates to the field of transformer production, in particular to a silicon steel sheet shearing device. Background Art

[0002] The announcement number is CN216881946U. Two silicon steel sheets are input from the upper and lower sides of the first partition plate, and are moved to the other side by the conveyor wheel to pass through the upper and lower sides of the second partition plate. The fixed hydraulic column presses the two silicon steel sheets, and the upper cutting hydraulic column presses the cutter downward through the pressure cutting plate and passes through the second pressure plate to cut the silicon steel sheet on the second partition plate. At the same time, the pressure cutting plate below drives the cutter to move upward through the pressure cutting plate and passes through the second pressure plate to cut the silicon steel sheet below the second partition plate, and then two silicon steel sheets can be cut out at one time.

[0003] In the above patent, the entire silicon steel sheet passes through horizontally. When shearing and forming the silicon steel sheet in this way, if the sheared silicon steel sheet gets stuck or is not completely sent out of the shearing position, the silicon steel sheet sheared last time will interfere with the silicon steel sheet to be sheared next time. At the same time, if the waste at the shearing position is not completely sent out, it will affect the shearing quality of the entire silicon steel sheet. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] like Figure 1-Figure 8 As shown, a silicon steel sheet shearing device includes a frame 1, a feeding mechanism 3 for pushing silicon steel sheets downward is arranged on both sides of the frame 1, two symmetrical arc plates 6 are arranged on the lower side of the frame 1, and also includes a shearing mechanism 4 for shearing and forming the silicon steel sheets and a pushing mechanism 5 for pushing the shearing mechanism 4 to act;

[0032] In this embodiment: the shearing mechanism 4 includes a locking nut 42, the locking nut 42 is fixed at the positions on both sides of the frame 1, the locking nut 42 is connected to the adjusting screw 41 by threading, and a forming plate 43 is fixed at one end of the adjusting screw 41 extending into the frame 1, and a punching plate 44 is provided on the side of the forming plate 43 away from the adjusting screw 41, and an air hole for adsorbing the sheared silicon steel sheet is opened inside the punching plate 44, and a vacuum generator 45 is fixed at the lower end of the air hole of the punching plate 44, and the adjusting screw 41 is rotated inside the locking nut 42 to adjust the distance between the forming plate 43 and the punching plate 44, and the vacuum generator 45 on the punching plate 44 generates suction in its air hole, so as to adsorb and fix the sheared silicon steel sheet;

[0033] In this embodiment, the pushing mechanism 5 includes a connecting seat 51, two symmetrically arranged connecting rods 52 are hinged on the lower side of the connecting seat 51, and a pushing frame 53 is hinged at the lower end of the connecting rod 52. One end of the pushing frame 53 is fixed to the side of the punching and shearing plate 44, and a return spring 54 is arranged at the end of the two pushing frames 53 close to each other. Limiting wheels 55 are arranged on the upper and lower sides of the pushing frames 53, and a limiting shaft 8 for supporting the limiting wheel 55 is arranged at the center position of the limiting wheel 55. A first sliding rod for supporting the return spring 54 is fixed at the end of the two pushing frames 53 close to each other. The upper and lower sides of the pushing frames 53 are provided with a plurality of sliding rods for facilitating the limiting wheel 55 to move freely. An internal rolling groove, sliding grooves are provided on the front and rear sides of the frame 1 to facilitate the horizontal movement of the first sliding rod of the pushing frame 53. A hydraulic rod 2 is fixed on the top of the frame 1 to push the connecting seat 51 downward. A collecting groove 7 is provided on the front side of the frame 1 to facilitate the collection of the sheared silicon steel sheets. The connecting seat 51 is pushed downward by the telescopic part of the hydraulic rod 2. The lower ends of the two connecting rods 52 are opened outward by the downward movement of the connecting seat 51. The corresponding pushing frame 53 is pushed outward by the opened two connecting rods 52, and then the punching plate 44 at the end of the pushing frame 53 cooperates with the forming plate 43 to shear the silicon steel sheets.

[0034] In this embodiment: the feeding mechanism 3 includes two feeding racks 31, and the two feeding racks 31 are symmetrically arranged on the inclined planes on both sides of the frame 1. A feeding roller 32 is rotatably connected inside the feeding rack 31, and a feeding motor 33 for driving the feeding roller 32 to rotate is fixed to the front side of the feeding rack 31. A silicon steel sheet coil 34 is arranged on the upper side of the feeding rack 31, and a positioning ring is provided on the outer side of the feeding roller 32 to prevent the silicon steel sheet coil 34 from axial deviation during the unwinding process. The silicon steel sheet coil 34 is pressed on the feeding roller 32, and then when the feeding motor 33 drives the feeding roller 32 to rotate, the silicon steel sheet coil 34 rotates synchronously in the opposite direction, and then the silicon steel coil on the outer side of the silicon steel sheet coil 34 is unwound.

[0035] Working principle: When in use, first place a whole roll of silicon steel sheet coil 34 on the feeding rack 31, press the silicon steel sheet coil 34 on the feeding roller 32, and clamp the front and rear sides of the silicon steel sheet coil 34 through the positioning ring on the feeding roller 32, so as to prevent the silicon steel sheet coil 34 from moving axially during the unwinding process, thereby causing the silicon steel sheet to deviate from between the forming plate 43 and the punching plate 44;

[0036] When the silicon steel sheet is located between the forming plate 43 and the punching plate 44, the adjusting screw 41 is rotated to allow it to be screwed into the locking nut 42, and then the forming plate 43 is pushed to fit the side of the silicon steel sheet by the adjusting screw 41. Then, the telescopic part of the hydraulic rod 2 pushes the connecting seat 51 to move downward, and the lower ends of the two connecting rods 52 are opened outward by the downward movement of the connecting seat 51. The corresponding push frame 53 is pushed outward by the opened two connecting rods 52, and then the punching plate 44 at the end of the push frame 53 cooperates with the forming plate 43 to shear the silicon steel sheet. In this process, the limiting wheel 55 rolls in the groove of the push frame 53, and then the friction is reduced when the push frame 53 is pushed by the connecting rod 52.

[0037] After the forming plate 43 and the punching and shearing plate 44 finish shearing the silicon steel sheet, the vacuum generator 45 is ventilated and generates suction in the pores of the punching and shearing plate 44, and then the sheared silicon steel sheet is adsorbed, and then the sheared silicon steel sheet waste falls below it. During this process, the telescopic part of the hydraulic rod 2 drives the connecting seat 51 to move upward, and the lower end of the connecting rod 52 begins to gather under the contraction action of the reset spring 54, and then the punching and shearing plate 44 with the silicon steel sheet adsorbed is connected to the push frame 53 to pull back. When the silicon steel sheet on the punching and shearing plate 44 moves with it to the upper side of the arc plate 6, the vacuum generator 45 stops supplying air, and then the pores on the punching and shearing plate 44 no longer generate suction, and the silicon steel sheet slides from the punching and shearing plate 44 to the arc plate 6, and is introduced into the collecting tank 7 through the arc plate 6 for collection.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
