Abstract

The utility model discloses a die rotary cutting mechanism. The mechanism successively comprises an upper die base, an upper pad, an upper clamp plate, a backstop plate, a stripper plate, a lower die plate, a lower pad and a lower die base. The mechanism further comprises a fixing plate, a plurality of fixing blocks, a plurality of movable blocks, and a plurality of cutter edges. The upper ends of the plurality of fixing blocks are fixedly disposed at the periphery of the fixing plate. The lower ends of the plurality of fixing blocks are disposed at the periphery of the movable block. Cooperated sliding rails are disposed between the plurality of fixing blocks and the movable blocks. The plurality of cutter edges are fixed to the movable block. The mechanism further comprises a spring and a first push rod. The upper end of the first push rod is abutted against the spring and disposed in the upper die base. The lower end of the first push rod slidingly passes through the upper pad and the upper clamp plate, and the end surface of the first push rod is fixed to the fixing plate. The die rotary cutting mechanism utilizes pure mechanical principles, is low in cost, and overcomes the defect that the conventional mechanism needs a secondary processing for generation. The mechanism is concise in structure and convenient in replacement, and needs no maintenance of professional personnel. A cut end surface is flat with an accurate height tolerance.

Description

Mould rotary cutting mechanism

Technical field

The utility model relates to a kind of rotary cutting mechanism, relates in particular to a kind of mould rotary cutting mechanism.

Background technology

At die industry, the product needed of processing is carried out leftover pieces excision, after when excision generally needs product stripping, adopts mechanical or manual mode again, inefficiency not only, and cut section out-of-flatness.

Summary of the invention

In order to overcome above-mentioned defect, the utility model provides a kind of mould rotary cutting mechanism, and after mould molding, carry out leftover pieces and cut, operation reduction, section is smooth.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of mould rotary cutting mechanism, comprise the upper bolster setting gradually, upper padding plate, train wheel bridge, baffle plate, stripper plate, lower bolster, lower bolster and die shoe, and fixed head, several fixed blocks, movable block and several edges of a knife, several fixed block upper ends are fixed at respectively described fixed head surrounding, several fixed block lower ends lay respectively at described movable block surrounding, between several fixed blocks and movable block, be provided with the sliding rail cooperatively interacting, several edges of a knife are individually fixed on described movable block, separately be provided with spring and the first push rod, this first push rod upper end pushes against this spring and is placed in described upper bolster, and this first push rod lower end is slidably set in described upper padding plate and train wheel bridge and its end face is fixed on described fixed head.

As preferred version of the present utility model, on described fixed block, be provided with double wedge, on described movable block, be provided with recessed tooth, this double wedge forms described sliding rail along this recessed tooth slippage.

As preferred version of the present utility model, treat that cropping of products is positioned on rocker piece, this rocker piece slides and is arranged on described lower bolster, and this rocker piece below is provided with the second push rod for this rocker piece of jacking.

The beneficial effects of the utility model are: this mould rotary cutting mechanism utilizes the relative motion structure of movable block and fixed block to realize the driving of the edge of a knife, belongs to pure theory of mechanics, more reliable and more stable with respect to cylinder or servo motor, and cost is lower; Changed the general layout that tradition needs secondary operations just can produce; Simple for structure, after long-term use after attrition, can self-changeable, it is convenient to change, and does not need professional to maintain, change; End face after cutting is smooth, and height tolerance is accurate.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1;

Fig. 3 is fixed block described in the utility model and movable block position relationship schematic diagram.

By reference to the accompanying drawings, make the following instructions:

1---upper bolster 2---upper padding plate

3---train wheel bridge 4---stop plate

5---stripper plate 6---lower bolster

7---lower bolster 8---die shoe

9---fixed head 10---fixed block

11---movable block 12---edge of a knife

13---sliding rail 14---spring

15---first push rod 16---product

17---rocker piece 18---second push rod

131---double wedge 132---recessed tooth

The specific embodiment

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.

As Figure 1-3, a kind of mould rotary cutting mechanism, comprise the upper bolster 1, upper padding plate 2, train wheel bridge 3, baffle plate 4, stripper plate 5, lower bolster 6, lower bolster 7 and the die shoe 8 that set gradually, and fixed head 9, several fixed blocks 10, movable block 11 and several edges of a knife 12, several fixed block upper ends are fixed at respectively described fixed head surrounding, several fixed block lower ends lay respectively at described movable block surrounding, between several fixed blocks and movable block, be provided with the sliding rail 13 cooperatively interacting, several edges of a knife are individually fixed on described movable block; Separately be provided with spring 14 and the first push rod 15, this first push rod upper end pushes against this spring and is placed in described upper bolster, and this first push rod lower end is slidably set in described upper padding plate and train wheel bridge and its end face is fixed on described fixed head.

On described fixed block, be provided with double wedge 131, be provided with recessed tooth 132 on described movable block, this double wedge forms described sliding rail 13 along this recessed tooth slippage.

Treat that cropping of products 16 is positioned on rocker piece 17, this rocker piece slides and is arranged on described lower bolster, and this rocker piece below is provided with the second push rod 18 for this rocker piece of jacking.

During work, by the first push rod, promoting fixed head moves, fixed head is when motion, because making movable block, the sliding rail arranging between fixed block and movable block moves along this sliding rail, thereby the edge of a knife being fixed on this movable block is moved, and then make the material generation deformation of processing, squeeze off effect, because the edge of a knife arranges, form annular, therefore can make the edge of a knife form clockwise ring cutting along product surrounding along the sliding rail of design.
