The lower plate 20 has a plurality of lower plate holes 22; the lower plate holes 22 are formed through the lower clamping plate 20 at the top and bottom and are concentric with the matching upper plate holes 12. In practice, the lower plate hole 22 may be a through hole or a screw hole.
The tightening bolts 30 have a tightening thread 32 on the outer peripheral sides of both ends, and extend through the upper and lower plate holes 12, 22, respectively, which are concentrically matched.
The tightening nuts 40 are screwed to the tightening threads 32 of the tightening bolts 30, and are pressed against the upper (lower) end surface of the upper (lower) clamping plate 10(20), and the distance and speed of the movement of the upper clamping plate 10 towards the lower clamping plate 20 direction are rapidly adjusted by the design (non-limiting) of the larger pitch (or the plurality of threads) of the tightening threads 32 of the tightening bolts 30. In practice, when the lower plate hole 22 is a screw hole (not shown), the fastening nut 40 corresponding to the screw lock can be omitted and directly screwed (not shown).
The nesting seat 50 has a lower flange 52 and a center post 54. The downward facing end surface of the lower flange 52 is locked in a default position on the lower clamping plate 20. The central pillar 54 is erected on the upper end surface of the lower flange 52, and the upper section of the central pillar passes through the pressing pillar 60 and one of the matched upper plate holes 12, and has a threaded section 542 on the outer peripheral side. In practice, the central column 54 provides the silicon steel sheet S1 for overlapping, and the pitch of the thread segment 542 is smaller than the tightening thread 32 of the tightening bolt 30 (without limitation of the present invention).
The compression leg 60 has an upper flange 62, a positioning leg 64 and a shaft opening 66. The upper flange 62 is locked at a default position on the downward end surface of the upper clamping plate 10. The positioning column 64 is vertically arranged on the downward end face of the upper flange 62. The axial hole 66 is formed through the compression leg 60 from the top to the bottom, and is concentric with the central leg 54 and one of the matching upper plate holes 12, so as to provide for the central leg 54 of the nesting seat 50 to extend through.
And the upper screw locking nut 70 is screwed on the outer peripheral side of the threaded section 542 of the central column 54 and presses against the upward end surface of the upper clamping plate 10, so that the distance and the speed of the upper clamping plate 10 and the locked pressing column 60 moving towards the lower clamping plate 20 are synchronously and finely adjusted.
The sleeves 34 are movably fitted around the outer peripheral sides of the tightening bolts 30 to limit the minimum distance between the upper and lower clamping plates 10, 20. In practice, the length of the sleeve 34 corresponds to the height of the core S to be formed.
The two opposite ends of the lifting lug 80 are respectively provided with a lug hole 82 and a lug thread 84; with the ear threads 84 engaging the threaded lock nut 70.
The washer 72 (prior art) is fitted around the outer periphery of the center post 54 and located between the upper clamp plate 10 and the lock nut 70. In practice, the gasket 72 may be a rigid gasket (e.g., made of metal) or a flexible gasket (e.g., made of plastic).

The upper clamping plate 10 is pressed by the pressing nut 40, and the displacement of the upper clamping plate 10 and the pressing column 60 locked thereon can be rapidly adjusted due to the larger pitch of the pressing threads 32 of the pressing bolt 30, so as to rapidly achieve the adjustment of the force of the pressing column 60 pressing against the silicon steel sheet S1.
The central pillar 54 (threaded section 542) is screwed by the screw nut 70, so as to further finely adjust the displacement of the upper clamping plate 10 and the pressing pillar 60 locked thereon, and finely adjust the force exerted by the pressing pillar 60 on the silicon steel sheet S1. The final compressed height of each silicon steel sheet S1 is limited by the length of the sleeve 34.
Thus, after the silicon steel sheets S1 are adhered to each other to form an iron core S, the operation is reversed to obtain the iron core S.
Referring to fig. 1 to 5, the lifting lugs 80 can be screwed with the screw nuts 70 to facilitate the mechanical lifting of the above-mentioned components, and the time for the silicon steel sheets S1 to stick in and out of the heating chamber H is accelerated.
