Description
Technical field
The utility model is related to a kind of automotive drum type braking piece production mould, and in particular to one kind need not be re-worked, pressure
Brake block die of the system with rivet hole.
Background technology
At present, automotive drum type braking piece is compressing and drilling mainly has following two modes：1：Tub circulates mould, main
If the raw material input die cavity that will be weighed up, then suppresses plus dividing plate, slice is circulated.There is compressing size uneven,
Dividing plate depanning takes piece, and the temperature difference is increased.The pressure maintaining period time is difficult to ensure that, causes interiors of products loose, unstable properties.2:Identity
And point chamber lifting mould, technique need it is preforming in advance after, cold base is put into die cavity, secondary hot pressing shaping is present preforming
Need raw material mobility high, be molded uneven, increase pre-forming device and cost of labor.The compressing pattern of both the above with
Afterwards, it is required for processing the rivet hole for needing on brake block in Special drilling equipment, secondary positioning, because outside brake block
Shape size is uneven, and the hole for coming outbreak out, size is unstable.In the brake block and brake shoe riveting process in later stage, it is difficult to wear riveting
Nail, and leaving gap causes the hidden danger that brake block is broken.And rig investment is big, and drill bit is lost and cost of labor accounting
Example is very big, and boring procedure produces dust polluting environment, increases raw material input cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of band rivet hole that can go out riveted holes with direct pressing
Brake block die.
The technical scheme that the utility model is used is：A kind of brake block die with rivet hole, it includes mutually fastening
Upper die plate and lower mode cavity, be arranged on upper die plate buckling surface seaming chuck, be arranged on seaming chuck in the middle of fixed guide pillar with
And middle fixed guide pillar two ends are arranged on for suppressing the activity core pulling guide pillar of rivet hole, it is provided with the seaming chuck and is led
Post holes, the activity core pulling guide pillar is arranged in guide pillar hole, and brake block ejection cylinder is further fixedly arranged on seaming chuck.
The voussoir for adjusting activity core pulling guide pillar position is provided with above activity core pulling guide pillar described in the utility model.
The utility model is provided with draw-in groove in the upper end of the guide pillar hole, and extension spring is provided with draw-in groove, the extension spring
One end is fixedly connected with the upper end of activity core pulling guide pillar, and the other end of extension spring is fixedly connected with draw-in groove, and the voussoir is taken out with activity
The upper end position of core guide pillar is corresponding.
Good effect of the present utility model is：The activity core pulling for being directly provided for suppressing riveted holes on seaming chuck is led
Bar, can be directly produced out the brake block with riveted holes, it is not necessary to additionally put into raw material, and the cost of raw material is greatly reduced.
And activity core pulling guide rod is movable to be arranged in guide rod hole, reasonable in design using mechanical structure, and simple to operate, practicality is high.
When needing to separate brake block, activity core pulling guide rod is retracted and is disengaged with brake block, is reduced brake block and is separated resistance, is conducive to
Brake block is separated.The position of activity core pulling guide rod can be adjusted according to the thickness of brake block simultaneously, only need to adjust voussoir i.e.
Position adjustments are capable of achieving, it is convenient and swift.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model upper die plate structural representation；
Fig. 3 is the utility model seaming chuck structural representation.
In the accompanying drawings, fixed guide pillar, 4- activity core pullings guide pillar, 5- voussoirs, 6- stop in the middle of 1- upper die plates, 2- seaming chucks, 3-
Car piece ejection cylinder, 7- lower mode cavities, 8- extension springs, 9- guide pillar holes.
Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, the utility model includes the upper die plate 1 for mutually fastening and lower mode cavity 7, is arranged on upper die plate 1
Seaming chuck 2 on buckling surface, be arranged on seaming chuck 2 in the middle of fixed guide pillar 3 and be arranged on the middle fixed two ends of guide pillar 3 and use
In the activity core pulling guide pillar 4 for suppressing rivet hole, guide pillar hole 9, the activity core pulling guide pillar 4 are provided with the seaming chuck 2
It is arranged in guide pillar hole 9, brake block ejection cylinder 6 is further fixedly arranged on seaming chuck 2.
The top of the activity core pulling guide pillar 4 is provided with the voussoir 5 for adjusting the position of activity core pulling guide pillar 4, the wedge
Block 5 is corresponding with the upper end position of activity core pulling guide pillar 4.The upper end of the guide pillar hole 9 is provided with draw-in groove, is set in draw-in groove
The one end for having extension spring 8, the extension spring 8 is fixedly connected with the upper end of activity core pulling guide pillar 4, and the other end and the draw-in groove of extension spring 8 are fixed
Connection.
Raw material when in use, are put into lower mode cavity 7 by the utility model, and forcing press drives the descending applying pressure of seaming chuck 2,
Promote voussoir 5 to move downward simultaneously and activity core pulling guide pillar 4 ejected into seaming chuck 2, after pressurize formed product, seaming chuck 2 is lifted,
In the presence of extension spring 8, the return of voussoir 5, the brake block after the retraction seaming chuck 2 of activity core pulling guide pillar 4, with casting departs from,
Riveted holes are formed, the fixed drive of guide pillar 4 in centre proposes product, and brake block ejects cylinder 6 and brake block is ejected into lead fixed with centre
Post 4 is separated.
The utility model increase activity core pulling guide pillar 4 on mould, directly can produce in production on brake block
Riveted holes, the punching work gone after eliminating, it is not necessary to additionally put into raw material, can effectively reduce equipment investment and it is artificial into
This, while the product size produced is stable, production qualification rate is high, and production cost is greatly reduced.
