The utility model relates to the technical field of small-sized rolled iron core manufacturing, in particular to a small-sized rectangular iron core centering and full-cutting device.
Background
The small rectangular roll iron core is centered and completely cut into two C-shaped iron cores with the same shape to form a small CD-shaped iron core, and the small CD-shaped iron core is widely applied to power transformers in sound systems, communication equipment and electrical control systems. The full cutting in the small rectangular iron core pair is an intermediate process step in the process of manufacturing the small CD-shaped iron core, and needs to be installed in an insulating sheath in the next assembly process step. The size range of the small rectangular iron core is 18-80 mm of the length of the inner ring, 10-30 mm of the width of the inner ring, 5-15 mm of the height and 5-20 mm of the thickness. The rectangular core described below refers to a small rectangular roll core of this size range. Because the insulating sheath used in the later process is formed by die pressing with the same specification and size, the length difference of the outer rings of the two C-shaped iron cores which are completely cut from the rectangular iron core pair is required to be less than or equal to 1MM, which is equivalent to the distance F between the nominal central line OO 'of the rectangular iron core and the actual cutting central line MM' to be less than or equal to 0.5MM, namely F is less than or equal to 0.5MM, and the reference is shown in figure 1.
The existing rectangular iron core centering and full cutting device for the specification and the size comprises a linear guide rail movement mechanism, a grinding wheel cutting machine, a cutting clamp and a cutting die assembly, and is shown in fig. 2 to 4. The cutting clamp 2 mainly comprises a frame 2-4, a nut 2-5, a 2 nd screw rod 2-6, a pressure plate 2-1 and a positioning groove 2-1-1 arranged in the center of the pressure plate, a guide rod 2-3 and a linear bearing 2-2, and is used for positioning and clamping a cutting die assembly 11. The cutting die assembly 11 consists of a 1 st cutting die 11-1, a 2 nd cutting die 11-2, a fixed column 11-3, a pressure plate 11-4 and a 1 st screw rod 11-5 which are of an integrated structure, the 1 st cutting die 11-1 is provided with a 1 st positioning block 11-1-1 and a 1 st cutting groove 11-1-2, the 2 nd cutting die 11-2 is provided with a 2 nd cutting groove 11-2-2 and a positioning surface 11-2-1, two stacked rectangular iron cores 1 are sleeved in the 2 nd cutting die 11-2, the width surfaces of the same side of the inner ring of the rectangular iron cores are closely contacted and connected with the positioning surface 11-2-1 of the 2 nd cutting die through a 1 st screw 11-5 and a pressing plate 11-4, and the cutting die assembly 11 is matched, positioned and contacted and connected with the positioning groove 2-1-1 of the pressing plate of the cutting clamp 2 through the 1 st positioning block 11-1-1.
The mounting, positioning and fixing mode of the rectangular iron core and the 1 st cutting die adopts single-side positioning and fixing, namely, one side width surface of the inner ring of the rectangular iron core is used as a reference positioning surface, and the position of a cutting groove in the cutting die is calculated and designed according to the size of the long edge of the inner ring of the rectangular iron core, so that the structure has the following defects:
(1) because the rectangular iron core is formed by winding the core mould, the external dimension of the core mould directly determines the dimension of the inner ring of the iron core, however, the external dimension of the core mould is influenced by the processing precision, the production batch and the abrasion generated in the working process, so that the length dimension of the inner ring of the iron core is different, and the existing cutting mould is positioned by one width side surface of the inner ring of the iron core, the F value of the inner ring of the iron core after being cut in a centering way is larger than 0.5mm, and the rectangular iron core becomes an unqualified product.
(2) The next procedure requires that two half iron cores cut from the center are respectively arranged in insulating sheaths with the same specification, so the distance F between two central lines is less than or equal to 0.5mm, because the cutting die is positioned by one width side surface of the inner ring of the rectangular iron core, and the detection is carried out by the length difference of the outer rings of the two half iron cores, and meanwhile, the deviation of the actual cutting central line of the rectangular iron core is influenced by the lamination thickness dimension error of the rectangular iron core.
(3) Because the cutting die is used for simultaneously cutting two rectangular iron cores once, when the length sizes of the two rectangular iron cores are greatly different, the width side surface of the inner ring of each rectangular iron core is used as a positioning reference, so that the common central line of the two rectangular iron cores cannot be found during cutting, the deviation of the two cut half iron cores to the nominal central line is large, and the two half iron cores become unqualified products. If the length tolerance of the inner rings of the rectangular iron cores is A +/-B = A +/-0.5 mm, when the width sides of the inner rings of the two rectangular iron cores are aligned, the maximum deviation between the nominal center lines of the two rectangular iron cores is 0.5 mm.
The above factors can cause the distance F between the nominal central line of the fully-cut rectangular iron core in the single-side positioning die set and the actual cutting central line to be more than 0.5 mm.
