Description
Technical field
The utility model relates to automobile diel field, is specifically related to a kind of automobile diel two-in-one with deburring of drawing, and is mainly used in accessories such as processing punching press automobile box spare.
Background technology
Present stamping parts of automobile, general all adopt draw earlier, the deburring mode of production of single mold of shaping again.All there are a lot of drawbacks from design, processing, die debugging in this mode of production to punching production, Sheet Metal Forming Technology complexity, mold materials waste are seriously, the processing cumulative errors are big, the pincers worker debugging work load is heavy, particularly need repeatedly die change in the punching production, increase the generation of jig frequency expense and security incident, had a strong impact on stamping production efficiency.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model is to propose a kind of automobile diel two-in-one with deburring of drawing, it can realize that a mold finishes the function of two molds, enhances productivity, thereby has realized the maximization of benefit.
The utility model is the technical scheme that its purpose of realization is taked: a kind ofly draw the automobile diel two-in-one with deburring, comprise die shoe, upper bolster, draw punch, draw die and draw blank holder, the described punch that draws is fixed on the die shoe, set installing plate on the described die shoe, described lower installation board is enclosed within and draws on the punch, and by drawing punch as guiding, establish first and second on the described lower installation board and draw blank holder and lower spring, described first draws blank holder is fixed on the lower installation board, is with second outside it and draws blank holder; Set firmly upper mounting plate on the described upper bolster, establish first and second on the described upper mounting plate and draw die and upper spring, wherein second draw die and be fixed on the upper mounting plate, first draws die draws die as guiding with second.
Described first draws blank holder is used as the deburring punch when deburring, described second draws blank holder is used as the deburring stripper when deburring, and described first draws die is used as the deburring holding pad when deburring, and described second draws die simultaneously also as the deburring die.
Described lower spring and upper spring are nitrogen spring.
The beneficial effects of the utility model:Realized that a mold finishes the function of two molds, saved die making shop merchant's production cost, and solved that the mould that runs into changes the outfit slowly, production efficiency is low, stamping products is of low quality and problem such as security incident is many in punching production, whole punching course is can be more quick, safety, high efficiency, the high-quality production of carrying out stamping parts, thereby has improved ram efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the utility model drawing die working state schematic representation;
Fig. 2 is the utility model trimming die working state schematic representation.
The specific embodiment
Present embodiment is an example with the automotive oil tank flap, and its product depth is about 100mm, and drawing and the two-in-one mould structure of deburring of accessories such as all the other similar automobile box spares can be with reference to this example.
As shown in Figure 1, 2, the utility model comprises die shoe 1, upper bolster 2, draws punch 3, draws die and draws blank holder, draws punch 3 and is fixed on the die shoe 1.Set installing plate 10 on the die shoe 1, lower installation board 10 is enclosed within and draws on the punch 3, and by drawing punch 3 as guiding.Establish first and second on the lower installation board 10 and draw blank holder 4,5 and lower spring 8.First draws blank holder 4 is fixed on the lower installation board 10, is with second outside it and draws blank holder 5; Set firmly upper mounting plate 11 on the described upper bolster 2, establish first and second on the described upper mounting plate 11 and draw die 6,7 and upper spring 9, wherein second draw die 7 and be fixed on the upper mounting plate 11, first draws die 6 draws die 7 as guiding with second.First draws blank holder 4 also is used as the deburring punch when deburring, described second draws blank holder 5 also is used as the deburring stripper when deburring, described first draws die 6 also is used as the deburring holding pad when deburring, described second draws die 7 also is used as the deburring die when deburring.Lower spring 8 and upper spring 9 all adopt nitrogen spring.
The whole punching course that the utility model draws with the two-in-one automobile diel of deburring can resolve into two parts:
1. drawing process: second draws blank holder 5 under the effect of lower spring 8, deburring stroke of jack-up, make second to draw blank holder 5 and first and draw blank holder 4 and draw punch 3 profiles and coincide, first draws die 6 under the effect of upper spring 9, deburring stroke of jack-up, make first to draw die 6 and second and draw die 7 profiles and coincide, then under the effect of lathe air cushion, the lathe push rod withstands on the lower installation board 10, make two to draw blank holder and reach and draw stroke, two draw die and push down plate, and the lathe upper table surface is descending, finishes drawing process;
2. after deburring process, mould were finished and drawn, second drew die as the deburring die, and second draws blank holder as the deburring stripper, and the deburring die is pushed down the deburring stripper, continued a descending deburring stroke under the effect of lathe upper table surface, finished the deburring process; After deburring was finished, the lathe upper table surface was up, and the lathe push rod falls in the lathe following table, under the effect of upper and lower nitrogen spring, finished the discharging of plate, drew this moment, the technology content of deburring is all over;
In the deburring process, upper and lower nitrogen spring is compressed, and deburring is a pier death situation attitude when finishing.
Above-mentioned only is embodiment of the present utility model, and to one skilled in the art, the utility model has multiple change and variation.Allly within invention thought of the present utility model and principle, make any modification, be equal to replacement, improve etc., all should be included within the protection domain of the present utility model.
