Abstract
The utility model relates to a processing die of a straight fluted dual-head drill. The die comprises an upper template and a lower template which are oppositely arranged, wherein a die cavity is formed between the upper template and the lower template; an upper positioning block positioned in the upper template and a lower positioning block positioned in the lower template are respectively arranged on the upper part and the lower part of the middle part of the die cavity; the upper positioning block is supported by an upper spring arranged in the upper die cavity; and the lower positioning block is supported by a lower spring arranged in the lower die cavity. The straight fluted dual-head drill can be molded at one time by the die provided by the utility model, so the production efficiency is greatly improved, and the consistency and the interchangeability of the product are high.
Description
Technical field
The utility model relates to the processing mold of straight trough twin tip drill, belongs to cutter processing equipment technical field.
Background technology
The processing mode of existing straight trough twin tip drill is generally intermittenceization processing, i.e. first in the processing double end, and framework other end then, this form processing working (machining) efficiency is low, and because twice processing, the uniformity at two is difficult to effectively guaranteed.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of processing mold that makes the straight trough twin tip drill of the disposable machine-shaping of straight trough twin tip drill.
The technical scheme of the utility model employing is for this reason: the utility model comprises corresponding cope match-plate pattern and lower bolster; Form die cavity between cope match-plate pattern and the lower bolster; The upper and lower at die cavity middle part is respectively equipped with last locating piece that is in the cope match-plate pattern and the following locating piece that is in the lower bolster; Last locating piece is supported by the upper spring that is arranged in the upper cavity, and following locating piece is supported by the lower spring that is arranged in the lower mode cavity.
The utility model has the advantages that: the mould of the utility model can make the disposable forging molding of straight trough twin tip drill, has not only increased substantially production efficiency, and good product consistency, interchangeability are good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is that cope match-plate pattern, 2 is that lower bolster, 3 is that upper spring, 4 is that last locating piece, 5 is that die cavity, 6 is a locating piece under lower spring, 7 is among the figure.
The specific embodiment
The utility model comprises corresponding cope match-plate pattern 1 and lower bolster 2; Form die cavity 5 between cope match-plate pattern 1 and the lower bolster 2; The upper and lower at die cavity 5 middle parts is respectively equipped with the last locating piece and 4 that is in the cope match-plate pattern 1 and is in the following locating piece 7 in the lower bolster 2; Last locating piece 4 is supported by the upper spring 3 that is arranged in the upper cavity, and following locating piece 4 is supported by the lower spring 6 that is arranged in the lower mode cavity.
The two ends, middle part of the utility model die cavity are that two semicircles carry out matched moulds, and positive middle part is a part of not wanting sex change for one section, and we are designed to locating piece 4, following locating piece 7 to this part; Last locating piece 4, down locating piece 7 to close part just be prefabricated blank diameter, when cope match-plate pattern 1, when lower bolster 2 lifts, last locating piece 4, locating piece 7 can be under spring action down; Stretch out a distance that configures; Blanking in the time of can carrying out when lifting to terminal point when cope match-plate pattern 1, lower bolster 2 matched moulds, at first is to go up locating piece 4, following locating piece 7 under the effect of spring; Workpiece pressing; Make the forging and pressing correct position at two ends, forging goes out to be with shaping blank, and the correct grinding cylindrical puts the first edge on a knife or a pair of scissors and just accomplished the production and processing of straight trough twin tip drill after corase grind cylindrical, heat treatment then.
