Abstract
The utility model discloses an activity is dashed for cold -heading mould, include: the die shell, the die shell is hollow structure be provided with the die core in the die shell, reciprocating motion can be to the die core in the die shell, the die in -core is provided with one and dashes the stick the below that dashes the stick is provided with an independent fundamental mode thimble, the axle center that dashes the stick with the axle center of fundamental mode thimble is located same straight line, be provided with the spring in the top of die core, the die shell. In this way, the utility model discloses can solve the problem of blank axis unstability.
Description
Technical field
This utility model relates to cold-heading field, particularly relates to a kind of movable punching for cold upsetting die of car。
Background technology
When cold-heading deformation shapes, when the upsetting ratio of product, (S=L/D is compared in upsetting, L represents head formation length, D represents the diameter of wire rod) more than 3 time, blank is easy for producing to be similar to the buckling of strut buckling, in addition the section of blank can not be substantially flat, is just subject to the interference of a component force being perpendicular to axis, exacerbates buckling trend during such jumping-up。It is uncontrolled that will to develop into vertical bending folded, form waste product, especially because metal is distributed irregular in impression, part impression cannot be full of and in another part impression metal too much to die joint flow, cause the sharply increase of plastic force, produce bigger unbalance loading, mold damage and equipment, time serious can vexed car, to produce very harmful, should make great efforts to prevent。
Utility model content
This utility model is mainly solving the technical problems that provide a kind of movable punching for cold upsetting die of car, it is possible to the problem solving blank axis unstability。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of movable punching for cold upsetting die of car, including: punch die shell, described punch die shell is hollow structure, it is provided with die center in described punch die shell, described die center can move reciprocatingly in punch die shell, a punching rod it is provided with in described die center, described punching rod be arranged below an independent main mould thimble, the described axle center of punching rod is positioned at same straight line with the axle center of described main mould thimble, is provided with spring in the top of described die center, punch die shell。
Preferably, above described punching rod, in spring, it is provided with cushion block。
Preferably, described punching is excellent and is used for placing blank between main mould thimble, and described blank is positioned on main mould thimble。
The beneficial effects of the utility model are: this utility model carries out jumping-up by mobilizable die center, blank can be kept away and exempt from axis unstability, and have that technique is simple, adapt to the advantages such as wide, stock utilization is high, die life is higher, productivity ratio is higher, production cost is relatively low。
Accompanying drawing explanation
Fig. 1 is this utility model structural representation for movable punching one preferred embodiment of cold upsetting die of car；
Fig. 2 is the structural representation that another state is rushed in the shown activity for cold upsetting die of car；
In accompanying drawing, the labelling of each parts is as follows: 1, spring, and 2, cushion block, 3, punch die shell, 4, punching rod, 5, die center, 6, main mould thimble, 7, blank。
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining。
Referring to Fig. 1 and Fig. 2, this utility model embodiment includes:
A kind of movable punching for cold upsetting die of car, including: punch die shell 3, described punch die shell 3 is hollow structure, it is provided with die center 5 in described punch die shell 3, described die center 5 can move reciprocatingly in punch die shell 3, is provided with a punching rod 4 in described die center 5, described punching rod 4 be arranged below an independent main mould thimble 6, the described punching rod axle center of 4 is positioned at same straight line with the axle center of described main mould thimble 6, is provided with spring 1 in the top of described die center 5, punch die shell 3。
As it is shown in figure 1, when blank 7 enters die center, rush rod 4 and main mould thimble 6 extrusion billet 7, die center 5 moves upward, and finally blank 7 shapes as in figure 2。
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model。
