Description
Technical field
The utility model relates to a kind of mould, specifically a kind of nest hole forming, punching die of wheel rim.
Background technology
The same industry generally adopts double end hydraulic pressure nest hole special equipment to wheel rim nest hole forming and punching processing at present, but this equipment price is high-spirited expensive, complicated operation, and working (machining) efficiency is low.And equipment is in use in case damage not only maintenance cost height, and maintenance complicacy.
Summary of the invention
The utility model provides wheel rim nest hole, punching die a kind of with low cost, simple to operate in order to overcome the deficiency of prior art.
To achieve these goals, the utility model has designed a kind of nest hole forming, punching die, it is characterized in that: comprise that upper shuttering reaches formwork down, be provided with match plate up and down between the formwork, and the inner chamber that forms; Be provided with the die shank that exposes in the said upper shuttering, offer through hole in the die shank; Be provided with the department's tube that exposes in the following formwork, department tube top is provided with corresponding convexity with the lower shell bottom and cooperates; Be provided with the bulb forming convax mould in the said department tube, the bulb forming convax mould first half exposes to department's tube, and the termination at bulb forming convax mould top contacts with die shank, and head bottom part is that interior arc structure and bulb forming convax mould main body are carried out excessively; Be provided with elastomeric element between the upper surface of said department tube and the match plate, and end one side of elastomeric element is that the external arc structure cooperates with the interior arc structure of bulb forming convax mould head bottom part; Also be provided with slide block in the said chamber; Slide block is in a zigzag, and an end passes in the through hole of die shank; The outside of the other end connects towards pin;, and fix through another elastomeric element and the base in the following formwork greater than diameter towards the diameter of pin termination, in the said department's tube that exposes towards the other end insertion of pin towards the pin head bottom part towards the pin main body.
Described nest hole forming, punching die also comprise a bulb molding concave die that is used to cooperate the moulding of bulb forming convax mould.
Described elastomeric element and another elastomeric element are excellent power glue.
The utility model is compared with prior art, can on common punch press, once accomplish the nest hole forming and the punching processing of wheel rim, not only mould simple in structure, versatility is wide, and uses punching apparatus to drive Mould Machining, its working (machining) efficiency is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the rim structure figure after employing the utility model Mould Machining.
Fig. 3 is the side view of Fig. 2.
Referring to Fig. 1 to Fig. 3,1 is upper shuttering; 2 are following formwork; 3 is match plate; 4 is die shank; 6 is through hole; 7 are department's tube; 8 is the bulb forming convax mould; 9 is interior circular arc; 10 is external arc; 11 is slide block; 12 is towards pin; 13 is base; 14 is the bulb molding concave die; 15,16 is excellent power glue; 17 is chamber; 18 wheel rims; 19 is the nest hole; 20 is the hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises that upper shuttering 1 reaches formwork 2 down, is provided with match plate 3 up and down between the formwork, and the inner chamber 17 that forms.Wherein be provided with the die shank 4 that exposes in the upper shuttering 1, offer through hole 6 in the die shank 4; Be provided with the department's tube 7 that exposes in the following formwork 2, department tube 7 tops are provided with corresponding convexity with lower shell 2 bottoms and cooperate.Be provided with bulb forming convax mould 8 in the department tube 7, bulb forming convax mould 8 first halves expose to department's tube 7, and the termination at bulb forming convax mould 8 tops contacts with die shank 4, and head bottom part is that interior circular arc 9 structures and bulb forming convax mould main body are carried out excessively; Be provided with excellent power glue 15 between the upper surface of said department tube 7 and the match plate 3, and end one side of excellent power glue 15 is that external arc 10 structures cooperate with the interior arc structure of bulb forming convax mould 8 head bottom part; Also be provided with slide block 11 in the said chamber 17; Slide block 11 is in a zigzag, and an end passes in the through hole 6 of die shank 4; The outside of the other end connects towards pin 12;, and fixing through another excellent power glue 16 towards the diameter of pin 12 terminations with the bases 13 in the following formwork 2 towards the pin head bottom part greater than diameter towards the pin main body, in the department's tube 7 that exposes towards the other end insertion of pin 12.
During mold work; Earlier bulb molding concave die 14 is placed the inner surface of wheel rim; Die shank 4 is moved downward, department's tube 7 is pressed onto wheel rim 18 back stop motions again, and bulb forming convax mould 8 continues down motion; Department tube 7 compresses wheel rim 18, and bulb forming convax mould 8 is forming nest hole 19 on wheel rim 18 under the cooperation of bulb molding concave die 14.When 8 stop motions of bulb forming convax mould, under the effect of excellent power glue 15, make it return; At this moment punch press is made bar and is driven slide block 11 and make towards pin 12 and move downward; Form hole 20 towards pin 12 punching on the nest hole 19 of wheel rim 18; Accomplish after the punchings return under another excellent power glue 16 effects towards pin 12, thereby once accomplish nest hole forming and punching processing.
