Abstract

The utility model belongs to the field of cold punching and forming mold, and particularly relates to a one-off inward side cutting jig. The one-off inward side cutting jig comprises an upper mold, a lower mold and an outer guide post for connecting the upper mold with the lower mold, wherein a product is located between the upper mold and the lower mold; the one-off inward side cutting jig is characterized by further comprising a side cutting knife and a waste knife both located at two sides between the upper mold and the lower mold respectively; the side cutting knife and the waste knife form an integral cutting body; the integral cutting body is connected to movable slotting tools. According to the jig, the slotting tools at two sides move transversely under the driving of stop pieces, the stop pieces also have a limiting function, the slotting tools drive the side cutting knife to move, the waste is a whole circle when the side cutting knife cuts off the waste inwards, the side cutting knife moves forwards in an interrupted manner at this moment, the waste knife cuts off the waste into multiple small sections, and the waste falls off from multiple blanking holes formed in corresponding places of a lower packing plate. The one-off inward side cutting jig has small positioning error and small tool marks of side cutting, and reduces the procedure of burring in the following process as the burrs point inwards.

Description

Once cut to the inside tool

Technical field

The utility model belongs to the cold-punching molding mould applications, is specifically related to a kind of tool of once cutting to the inside.

Background technology

When the outer Sales primary side of notebook product is cut on the market at present, can only cut laterally, the product waste material can't blanking when cut to the inside.

The utility model content

The purpose of this utility model is to overcome the problems referred to above, provide that the little side cut-grafting of a kind of position error tool marks are little, burr inwardly reduce after processing procedure burr removing operation once cut to the inside tool.

To achieve these goals, the technical scheme that the utility model adopts is: once cut to the inside tool, comprise upper die and lower die and the outer guiding post that is connected upper and lower mould, product is between upper die and lower die, it is characterized in that: the side cutting knife and the waste knife that also comprise both sides between upper die and lower die, it is whole that side cutting knife and waste knife form a cutting, and described cutting is whole to be connected with removable slotting tool.

The aforesaid tool of once cutting to the inside, described slotting tool is arranged at patrix and is connected with block, and block promotes slotting tool transverse shifting between upper and lower mould.

The aforesaid tool of once cutting to the inside, described patrix is provided with upper bolster, upper padding plate, train wheel bridge, upper de-plate from top to bottom, described counterdie is provided with male model, lower bolster, die shoe, bottom seat pad, bottom plate from top to bottom, and product is positioned between de-plate and male model.

The aforesaid tool of once cutting to the inside, the male model outside is stretched out at described product two ends, and the product two ends are whole near cutting, and cutting integral body is followed slotting tool transverse shifting between upper and lower mould, the side cutting knife is cut the whole circle waste material of product formation to the inside, and waste knife is cut into some sections by whole circle waste material.

The aforesaid tool of once cutting to the inside, described lower bolster is provided with some material-dropping holes corresponding to the cutting integral position.

The aforesaid tool of once cutting to the inside, be provided with screw in described patrix.

Tool of the present utility model, the both sides slotting tool promotes transverse shifting by block, block also plays position-limiting action, slotting tool promotes the side cutting knife and moves, and when the side cutting knife inwardly cuts waste material, waste material is a whole circle, at this moment the side cutting knife intermittently moves ahead, waste knife is cut into a plurality of segments by waste material, and a plurality of material-dropping holes have been opened in the lower bolster corresponding position, and waste material can fall.This once cuts tool to the inside, and the little side cut-grafting of position error tool marks are little, and burr inwardly reduce the work of rear processing procedure burr removing.

The accompanying drawing explanation

Fig. 1 is structure chart of the present utility model;

Wherein, 1 outer guiding post, 2 waste knifes, 3 screws, 4 slotting tools, 5 side cutting knifes, 6 upper bolsters, 7 upper padding plates, 8 train wheel bridges, de-plate on 9,10 male models, 11 lower bolsters, 12 die shoes, 13 bottom seat pads, 14 bottom plates, 15 blocks.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

According to Fig. 1, once cut to the inside tool, comprise upper die and lower die and the outer guiding post 1 that is connected upper and lower mould, product is between upper die and lower die, it is characterized in that: the side cutting knife 5 and the waste knife 2 that also comprise both sides between upper die and lower die, it is whole that side cutting knife 5 and waste knife 2 form a cutting, and described cutting is whole to be connected with removable slotting tool 4.

Slotting tool 4 is arranged at patrix and is connected with block 15, and block 15 promotes slotting tool 4 transverse shifting between upper and lower mould.

Patrix is provided with upper bolster 6, upper padding plate 7, train wheel bridge 8, upper de-plate 9 from top to bottom, and described counterdie is provided with male model 10, lower bolster 11, die shoe 12, bottom seat pad 13, bottom plate 14 from top to bottom, and product is positioned between de-plate 9 and male model 10.

Male model 10 outsides are stretched out at the product two ends, and the product two ends are whole near cutting, and cutting integral body is followed slotting tool 4 transverse shifting between upper and lower mould, and side cutting knife 5 is cut the whole circle waste material of product formation to the inside, and waste knife 2 is cut into some sections by whole circle waste material.

Lower bolster 11 is provided with some material-dropping holes corresponding to the cutting integral position.

Be provided with screw 3 in patrix.

Tool of the present utility model, both sides slotting tool 4 promotes transverse shifting by block 15, block 15 also plays position-limiting action, slotting tool 4 promotes side cutting knife 5 and moves, and when side cutting knife 5 inwardly cuts waste material, waste material is a whole circle, waste knife 2 is cut into a plurality of segments by waste material, at this moment side cutting knife 5 blank that intermittently moves ahead, a plurality of material-dropping holes have been opened in lower bolster 11 corresponding positions, and waste material can fall.This once cuts tool to the inside, and the little side cut-grafting of position error tool marks are little, and burr inwardly reduce the work of rear processing procedure burr removing.

Above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops on protection domain of the present utility model.
