Abstract
The utility model provides a rounding type expanding mould for manufacturing radial annular metal bellows, mainly comprising a mould seat, a lower mould plate, an upper mould cover and fan-shaped mould plates. Guide keys are fixed in a slide-groove of the fan-shaped mould plates, which are fixed with the mould seat through bolts, and shovel-shaped mould plates are uniformly distributed at a circumference formed between the fan-shaped mould plates. When the radial annular bellows are expanded to the extent that the external diameter of the radial annular bellows is equal to the required external diameter, the shovel-shaped mould plate fills an arc vacancy generated by the fan-shaped mould plates on the circumference surface to make the circumference of the bellows form a continuously smooth round. The utility model effectively solves stress concentration generated by multi corner angles at the circumference and reduces the waste product rate of the product.
Description
The utility model relates to a kind of rounding type expanding die, particularly a kind of manufacturing annular radial metal bellows rounding type expanding die.
At present, in the metal bellows manufacturing industry, mould therefor is made up of die holder, fan-shaped template, lower bolster, upper mould cover, cone, mandrel etc.Wherein, the fan-shaped template inner conical surface cooperates with cone, and cone moves and makes many outside slippage bulgings of fan-shaped template during work, so that reach the bellows bulging to required diameter.Like this, on annular radial bellows inner periphery, the multi-section circular arc room appears, these circular arc rooms are not because of directly being contacted linearly section by fan-shaped template, circular arc junction on straightway and inner periphery forms corner angle, produces stress and concentrates, and has shortened bellows service life, crackle can occur when serious, the bellows of making can not be used.
The purpose of this utility model is to provide a kind of annular radial bellows expanding die, it can be easily at the bellows bulging during to the needs external diameter, make the bellows inner circumferential surface form smooth full circle continuously, the stress that has solved the many places corner angle generation that occurs on its inner periphery is effectively concentrated.
The utility model is achieved in that all installs a shovel shape template between each fan-shaped template of mould, this shovel shape template is in all processes of bellows diameter bulging, all the time promote the outside slippage of fan-shaped template, when bulging arrives the required external diameter of bellows, shovel shape template is filled up the circular arc room that fan-shaped template produces on circumferential surface, make bellows form a complete circle.
The utility model only needs to have increased shovel shape template on original device, and is reasonable in design, simple in structure, solved the stress that produces on the bellows circumference and concentrated, and reduced the percent defective of this product.
Fig. 1 is a front view of the present utility model.
Fig. 2 is Figure 1A-A rotation profile.
Fig. 3 is the schematic diagram in the utility model bulging process.
Fig. 4, Fig. 5 are shovel shape template views.
Fig. 1 is as the Figure of abstract of present specification.
With reference to Fig. 1, this mould comprises that die holder (1), lower bolster (2), upper mould cover (10), fan-shaped template (3), feather key (4) are fixed in the chute of fan-shaped template (3), and they are connected by bolt (5) and die holder (1).Shovel shape template (11) in the mould is concentric with the O of this mold center point with fan-shaped template (3), and shovel shape template (11) is evenly distributed on the circumference of being formed between each fan-shaped template (3).Cone (6) outer conical surface cooperates with the internal conical surface of shovel shape template (11), fan-shaped template (3), mandrel (7) penetrates by the cone centre bore, one end is by locking nut (8) locking, and the other end is connected with hydraulic cylinder (not drawing among the figure) with die holder (1).The rubber bar (9) that resets is enclosed within on the step cylindrical of being made up of fan-shaped template (3) and shovel shape template (11).The cone angle that inclined-plane, shovel shape template shown in Figure 5 (11) front end both sides forms is 30 °～80 °.
With reference to Fig. 2, Fig. 3, during operation, cylinder force F is along direction shown in the arrow F1, mandrel (7) drives cone (6) and moves, at first with the shovel shape template (11) of cone (6) cone match, the inclined-plane, both sides that its inclined-plane, front end both sides progressively promotes fan-shaped template (3) increases external diameter, when bulging arrives required bellows diameter, the inner conical surface of fan-shaped template (3) all contacts with the male cone (strobilus masculinus) of cone (6), at this moment, fan-shaped template (3) has been formed a complete circle with shovel shape template (11); After finishing bulging, hydraulic cylinder resets, and directed force F is along direction shown in the F2, and mandrel (7) drives cone (6) and resets, and under the effect of rubber bar (9) that reset, shovel shape template (11) is at first return, and then drives fan-shaped template (3) and returns, and action is finished.
Claims (2)
1, a kind of rounding type expanding die, it mainly is made up of die holder (1), lower bolster (2), upper mould cover (10), fan-shaped template (3), feather key (4) is fixed in the chute of fan-shaped template (3), they are connected by bolt (5) and die holder (1), it is characterized in that it has shovel shape template (11) and is evenly distributed on the circumference of being formed between each fan-shaped template (3).
2, mould according to claim 1, it is characterized in that shoveling the cone angle that inclined-plane, shape template (11) front end both sides forms is 30 °～80 °.
