The present embodiment is based on the first embodiment, and partitions the table panel 110, and the negative pressure suction effects in different working areas do not affect each other. When light soft materials such as pearl wool and the like are punched, pearl wool with different sizes is often required to be selected according to products and specific applications such as packaging sizes. When the light soft material such as pearl wool to be punched is small in size and cannot cover all the working area of the table top 110, that is, cannot cover all the first air exhaust holes 111, if a single air exhaust device is adopted, negative pressure cannot be formed due to air leakage of the first air exhaust holes 111, and then the pearl wool cannot be sucked. After a plurality of working areas are adopted, as long as the pearl cotton covers one of the working areas, the pearl cotton can be sucked, and therefore the pearl cotton is prevented from being taken up.

Third embodiment

As shown in fig. 14, the present embodiment has substantially the same structure as the first embodiment, except that: in the cutting die, the first position-limiting portion is a first position-limiting hole 216, and the second position-limiting portion is a second position-limiting hole 222, that is, the positioning plate 210 is provided with the first position-limiting hole 216, and the mounting plate 220 is provided with the second position-limiting hole 222. The first position-limiting hole 216 is aligned with the second position-limiting hole 222, and the position-limiting member 240 connects the first position-limiting hole 216 and the second position-limiting hole 222. For example, the first position-limiting hole 216 and the second position-limiting hole 222 may be tapered through holes with diameters decreasing from top to bottom, and the position-limiting member 240 may be a taper pin. For example, one of the first limiting hole 216 and the second limiting hole 222 may be a threaded hole, the other may be a through hole, and the limiting member 240 may be a threaded fastener such as a screw or a bolt, one end of which extends into the through hole and the other end of which is engaged with the threaded hole. For example, the first position-limiting hole 216 may be a through hole with a countersunk hole at the upper end, and the position-limiting member 240 may be a pin or a nail with a screw head, the screw head is engaged with the countersunk hole, and the pin or the nail passes through the through hole and extends into the second position-limiting hole 222. The second position-limiting hole 222 may be a through hole or a blind hole that does not communicate with the lower end surface of the mounting plate 220. Preferably, in the above-mentioned manner of engaging the first position-limiting hole 216, the second position-limiting hole 222 and the position-limiting member 240, the position-limiting member 240 does not lock the first position-limiting hole 216 and the second position-limiting hole 222 at the same time, for example, the position-limiting member 240 is connected or in contact with the first position-limiting hole 216, and without detaching the position-limiting member 240 from the first position-limiting hole 216, the mounting plate 220 may be moved down to disengage the second position-limiting hole 222 from the position-limiting member 240, so that the mounting plate 220 may be removed and replaced. For example, if the limiting member 240 is connected or in contact with the second limiting hole 222, the mounting plate 220 can be moved down to separate the first limiting hole 216 from the limiting member 240 without detaching the limiting member 240 from the second limiting hole 222, so that the mounting plate 220 can be removed and replaced. For another example, the limiting member 240 can be easily inserted into or removed from the first limiting hole 216 and the second limiting hole 222, and after the limiting member 240 is removed, the mounting plate 220 can be replaced.

In other embodiments of the present invention, the blanking die mounting structure may include a plurality of sets of corresponding first and second retention holes 216 and 222, each of which may be spaced apart from a centerline of the positioning member 210 differently to accommodate mounting members 220 of different sizes.

Fourth embodiment

As shown in fig. 15, in the structure for mounting a blanking die according to the present embodiment, the groove 215 is a T-shaped groove, and the T-shaped groove also serves to prevent the mounting member from falling. The grooves 215 extend in the left-right direction of the positioning plate and include a set of grooves disposed on both sides of the center line and a middle groove disposed on the center line. The mounting piece matched with the T-shaped groove can be provided with T-shaped convex blocks matched with the T-shaped grooves, and the number of the T-shaped convex blocks can be 3, and the T-shaped convex blocks are respectively matched with 3T-shaped grooves. The remaining structure is substantially the same as that of the first embodiment described above.

Fifth embodiment

As shown in fig. 16, this embodiment has substantially the same structure as the first embodiment described above, except that: the electromagnet 212 in the cutting die is connected above the positioning member 210, and magnetically attracts the mounting member 220 through the positioning member 210. For example, the electromagnet 212 may be screwed on the positioning member 210, an external screw may be connected to a lower end of the electromagnet 212, and a screw hole may be provided at an upper end of the positioning member 210 so as to connect the electromagnet 212. The electromagnet 212 is conveniently wired in this position. The positioning member 210 is no longer provided with a counter bore, and the positioning member 210 has a simpler structure. Wherein the positioning member 210 may be aluminum and the mounting member 220 may be iron. In other embodiments of the present invention, the electromagnet 212 may also be installed below the positioning element 210, i.e. between the lower end surface of the positioning element 210 and the upper end surface of the mounting element 220, as long as the electromagnet 212 is not prevented from magnetically attracting the mounting element 220.

Finally, it should be emphasized that the above-described embodiments are merely preferred examples of the invention, which is not intended to limit the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
