Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1 to fig. 3, wherein fig. 1 is a schematic structural diagram of a punching die for reducing punching strain according to a preferred embodiment of the present invention; FIG. 2 is a schematic cross-sectional view of the molding assembly of FIG. 1; fig. 3 is a schematic view of a disassembled structure of the punching assembly shown in fig. 1. The utility model provides a reduce cut-out press that punches a hole and strain, including bottom plate 1 and roof 6, the top of bottom plate 1 is fixedly connected with becomes frame 2 and stand 4 respectively, and the quantity of stand 4 is four, the outer wall of four stands 4 all overlaps and is equipped with first spring 5, the internally mounted of roof 6 has punching assembly 7, the sliding sleeve 8 has all been run through to the inside of roof 6 and the both sides that are located punching assembly 7, the internally mounted of shaping frame 2 has forming assembly 3, forming assembly 3 is including seting up in the inside blanking hole 31 and the counter bore 32 of shaping frame 2, the inside of counter bore 32 is embedded to have snap ring 33, the top fixedly connected with shaping ring 34 of snap ring 33, mounting hole 35 has been seted up to the inner wall of counter bore 32, the internally mounted of mounting hole 35 has second spring 36, the outer end fixedly connected with bayonet lock 37 of second spring 36.

The mounting hole 35, the second spring 36 and the detent 37 are distributed in a perfect mirror image about the left side of the blanking hole 31. Pressing on snap ring 33 causes detent 37 to control compression of second spring 36, and when snap ring 33 is fully seated within counterbore 32, detent 37 springs back to force snap ring 33 into position.

The snap ring 33 and the forming ring 34 are made of high carbon steel respectively, and the cross section of the forming ring 34 is of a pointed cone structure. Steerable punching press post 72 extrusion panel beating when roof 6 descends to make panel beating and shaping ring 34 accomplish the extrusion, such design is compared in the upper and lower mould design of traditional plain noodles structure, and shaping ring 34 and its special construction of high carbon steel material can make at first the snap-apart when punching press the panel beating, thereby can prevent that the aperture from causing too much strain.

The inside sliding connection of shaping frame 2 has collecting box 10, and the inside of four sliding sleeves 8 is embedded to have a plurality of sliding pins 9.

Punching press subassembly 7 is including installing in the inside card post 71 of roof 6, and the bottom fixedly connected with punching press post 72 of card post 71, and locating hole 73 and linking groove 74 have been seted up to the inside of roof 6, and the inside of linking groove 74 is embedded to have a limiting plate 75, and the inside threaded connection of limiting plate 75 has positioning bolt 76. It is necessary to slide the stopper plate 75 from the engaging groove 74 to the top of the catch 71 and then the user inserts the set bolt 76 and rotates so that the stopper plate 75 is stably positioned with respect to the catch 71.

The section of the clamping column 71 is a conical structure, the sliding pins 9 are made of graphite materials, and the sliding pins 9 are distributed in an annular mode at equal intervals relative to the axes of the four sliding sleeves 8. When the sliding sleeve 8 and the upright post 4 slide in a contact manner, the sliding pin 9 can constantly keep lubricating with the upright post 4, and jamming can be effectively prevented.

The utility model provides a pair of reduce cut-out press that punches a hole and strain's theory of operation as follows:
