Description
Technical field
The utility model relates to the processing method field of core print work zone, the system of processing of particularly a kind of divergent die patrix core print work zone.
Background technology
Along with the high speed development that China's economic is built, the improving constantly of living standards of the people, the building trade development of China rapidly, wherein especially the demand of aluminium section bar aspect building and ornament materials constantly increases, and brings the broad development of aluminium alloy extruded mould thus.
The hot extrusion divergent die generally is made up of upper die and lower die, alignment pin and attachment screw four parts.As shown in Figure 1, tap hole 11 and core print 12 are arranged on hot extrusion divergent die patrix 1.Wherein, tap hole 11 is passages that metal leads to the type hole, and core print 12 is the shape and size that are used for forming the section bar inner chamber.Core print 12 is generally square structure (rectangle or square), and the dimensional accuracy of core print work zone 121 and surface roughness directly influence the service life (friction of ingot casting and core print work zone was just little when the bright and clean more production in surface was pushed) of dimensional accuracy, surface smoothness and the mould of section bar endoporus.
During past fine finishining core print 12, if circle is concentric with cylindrical, just use lathe fine finishining, if decentraction or other are not squares, just with CNC milling machine or spark-erosion machine tool fine finishining, square (rectangle or square) just use cutter and tool grinding machine fine finishining, owing to square four faces that have, cutter and tool grinding machine once can only be processed a face, after first face processes, need with another face of reprocessing behind the dial gauge centering, process a square core print just need four times centering just can finish the processing of whole patrix core print.Particularly between the core print work zone perpendicularity, have only precision to satisfy by cutter and tool grinding machine self.
With core print work zone, cutter and tool grinding machine fine finishining side, because the precision of cutter and tool grinding machine self is not high, adding man-hour is again to process by four centerings, so long processing time, core print work zone after the processing is poor (four the angle out of plumb of form accuracy not only, shape is a parallelogram), and the perpendicularity of square core print work zone and die face is also poor.Sometimes in order to satisfy the size (section bar wall thickness) after upper and lower mould assembles, have only according to the counterdie shape and size and process patrix core print work zone.Above method is long processing time not only, and can not fine finishining such as Fig. 2, Fig. 3 and the described core print 12 with number of degrees of Fig. 4.

The utility model is placed on the divergent die patrix 1 that will process on the circular division workbench 6 by circular division workbench 6 being placed on the workbench 4 of horizontal milling machine again, milling cutter 2 is contained in the main shaft of horizontal milling machine again.Only need rotational circle index table 6 respective angles after processing one side, drive divergent die patrix 1 simultaneously and follow rotation, and then the processing another side, successively all faces are machined.The utility model only need rotate the angle that needs just can process all faces successively.The utility model processing core print work zone only needs 1/3rd of cutter and tool grinding machine process time, and the core print work zone surface roughness after the processing low (it is following to reach Ra0.8um), and (four angle error of perpendicularitys are less than 2 for the form accuracy height of core print work zone
/), core print work zone vertical with die face (20mm is high, and up-down error is no more than 0.01mm), the positional precision of core print work zone is also high, the core print of all right processing belt number of degrees.Jia Gong core print work zone in this way is used to produce the product fine of extruding, die life height.
In above-mentioned steps 3) in the described milling cutter 2 that is installed in the horizontal milling machine main shaft can be two, the distance between two milling cutters is greater than the distance between the relative two core print work zones on the core print.Reduce the number of times of slewing circle index table 6, two milling cutters 2 are set improve process velocity.Two milling cutters are set seem particularly important, for example core print 12 of the core print 12 of square structure, regular hexagon structure etc. at the core print 12 of symmetry.By be provided with two milling cutters make process the one side on the core print work zone time, need not slewing circle index table 6 at once, only need vertically move workbench 4, core print work zone on this core print work zone opposite face is contacted with another milling cutter, can directly process the core print work zone on this core print work zone opposite face, reduce the time of a slewing circle index table 6.
Wherein, step 3) is specially: two milling cutters 2 are contained in respectively on the knife bar of horizontal milling machine, again knife bar are packed in the main shaft of horizontal milling machine, and with the fastening described knife bar of pull bar screw rod.
Step 4) is specially:
41) the processing first core print work zone;
42) treat the first core print work zone completion of processing after, vertically move the workbench of horizontal milling machine, with another milling cutter processing core print work zone relative with the first core print work zone;
43) treat the core print work zone completion of processing relative with the first core print work zone after, slewing circle index table respective angles, this angle is the angle between the two adjacent core print work zones, processes the second core print work zone, each core print work zone completion of processing on core print.
In order further to optimize technique scheme, in step 2) and step 3) between also comprise step:
2a) be placed on centering on the core print work zone,, make the core print work zone parallel, move the set lever of circular division workbench 6 behind the centering, make circular division workbench 6 fixing with the workbench 4 of milling machine if the handle of error with regard to rotational circle index table 6 arranged with the dial gauge gauge outfit.Before processing core print work zone, carry out centering earlier and handle, can guarantee that the core print work zone that processes has enough precision.
After processing one side, vertically move the workbench 4 of horizontal milling machine, core print work zone with another milling cutter processing another side, and use the miking size, make core print work zone width size reach designing requirement after, only need rotational circle workbench dividing arm, circular table is revolved to be turn 90 degrees, drive mould simultaneously and follow rotation, processing other faces with same method then, so just finished the processing of a cubic core print.If not four directions or six sides etc., only the number of degrees that need rotation to need just can process all faces successively.
