[0015] The beneficial effects of the present invention are as follows: the present invention is a transformer core fully automatic shearing production equipment that assists in the close-laying stamping of plates and does not require the replacement of its bottom plate and mold, and its specific implementation is as follows:
[0016] The operator first places the sheet on the feeding bottom plate, and then starts the driving motor. The driving motor drives the top pressure rod to rotate, and further drives the pressure rod wheel to rotate. While the pressure rod wheel rotates, it drives the pressure rod protrusion to squeeze the flip rod toward the sheet, and at the same time drives the bevel frame on the trapezoidal punching block to squeeze the sheet onto the notch groove of the feeding bottom plate. At the same time, since the side projection of the bevel frame is a right-angled triangle, it cooperates with the notch groove to produce a scissors-like effect to complete the punching with a small expansion. When the bevel frame squeezes the sheet, it is easy to tilt. By setting the guide notch through the fixed buckle, it will not rotate when it descends, and this problem can be avoided.
[0017] After the punching is completed, the movable groove drives the flip rod to continue to abut against the pressure rod wheel until the pressure rod protrusion on the pressure rod wheel is separated from the flip rod, and the flip rack on the flip wheel engages with the meshing gear, so that the trapezoidal punching block flips, and the above process is repeated to achieve the dense punching of the plate, effectively solving the waste problem. At the same time, the feeding of the plate is completed by other machines or manually, which does not belong to the invention point of the present invention, so it will not be repeated;
[0018] In order to make up for the problem of partial gap when the bevel frame is passed into the notched groove, when the trapezoidal punching block rotates, it drives the pushing plate to touch the touch plate through the guide inclined plate, drives the movable block away from the end of the guide movable plate close to the feeding bottom plate, and further drives the limit rod to slide out of the arc groove. At the same time, since the limit rods on the relative movable blocks are connected through a group of selection grooves on a flip circular plate, when one of the movable blocks is away from the feeding bottom plate, the flip circular plate is driven to rotate, and the clamping gap between the selection groove and the arc groove drives the limit rod to move, and the relative movable block is close to the feeding bottom plate and passes the gap-filling block into its notched groove and the notch of the bevel frame accessories, thereby realizing the function of filling the notched groove and avoiding the occurrence of vacancies during the stamping process of the bevel frame, which leads to a discount in the stamping effect.
[0019] The equipment has a simple structure and effectively utilizes the flipping of the trapezoidal punching block to achieve the effect of densely paving and punching the trapezoidal plate. At the same time, there is no need to replace its base plate and mold. It has good practicality and economy, and is beneficial to the promotion and use of the equipment.

[0034] Furthermore, the notch shape of the notch groove 11 is a superimposed surface of a main projection of the bevel frame 14 and a main projection of the bevel frame 14 after rotation along the flip rod 131 .

When the pressure rod wheel 32 rotates, it drives the pressure rod protrusion 321 to squeeze the flip rod 131 towards the plate direction, and at the same time drives the bevel frame 14 on the trapezoidal punching block 13 to squeeze the plate onto the notch groove 11 of the feeding bottom plate 1. At the same time, since the side projection of the bevel frame 14 is a right triangle, it cooperates with the notch groove 11 to produce a scissors-like effect to complete the punching with a small expansion. When the bevel frame 14 squeezes the plate, it is easy to tilt. By setting the guide notch 132 through the fixing buckle 35, it will not rotate when it descends.
[0037] Advantageously, a driving motor 311 is further provided on the fixed bracket 12 , and the driving motor 311 drives the pressing rod 31 to rotate.

At the same time, since the limiting rod 442 on the relative movable block 44 is connected through a group of selection grooves 431 on the flip circular plate 43, when one of the movable blocks 44 is away from the feeding bottom plate 1, it drives the flip circular plate 43 to rotate, and the clamping gap between the selection groove 431 and the arc groove 451 drives the limiting rod 442 to move, and the relative movable block 44 approaches the feeding bottom plate 1 and passes the gap-filling block 441 into the gap of its notch groove 11 and the notch of the bevel frame 14 accessories, thereby realizing the function of compensating for the notch groove 11.
[0042] Working principle of the present invention:
[0043] After the operator places the sheet on the feeding bottom plate 1, the driving motor 311 is started. The driving motor 311 drives the top pressure rod 31 to rotate and further drives the pressure rod wheel 32 to rotate. While the pressure rod wheel 32 rotates, it drives the pressure rod protrusion 321 to squeeze the flip rod 131 towards the sheet, and at the same time drives the bevel frame 14 on the trapezoidal punching block 13 to squeeze the sheet onto the notch groove 11 of the feeding bottom plate 1. At the same time, since the side projection of the bevel frame 14 is a right triangle, it cooperates with the notch groove 11 to produce a scissors-like effect to complete the punching with a small expansion. When the bevel frame 14 squeezes the sheet, it is easy to tilt. By setting the guide notch 132 through the fixing buckle 35, it will not rotate when it descends, so this problem can be avoided.
[0044] After the punching is completed, the movable groove 121 drives the flip rod 131 to continue to abut against the pressure rod wheel 32 until the pressure rod protrusion 321 on the pressure rod wheel 32 is separated from the flip rod 131, and the flip rack 331 on the flip wheel 33 engages with the meshing gear 34, so that the trapezoidal punching block 13 is flipped, and the above process is repeated to achieve the dense punching of the plate, effectively solving the waste problem. At the same time, the feeding of the plate is completed by other machines or manually, which does not belong to the invention of the present invention, so it is not repeated;
[0045] The locking plate 412 is engaged with the locking member 414 and the locking member 422 is engaged with the locking member 423. The locking member 412 is engaged with the locking member 423 by the spring 462. The locking member 462 is engaged with the locking member 423 in a manner similar to that of the locking member 462.
