Abstract
The invention discloses a one-time forging mold for a bicycle bearing. An upper die fixed seat is fixedly arranged on a punch pole of a punching machine; a lower die fixed seat is fixedly arranged on a working table of the punching machine; an upper die consists of an upper die core, an upper die core sleeve, a pressing column and an upper die fixing ring; the upper die core is plugged in the upper die core sleeve; the pressing column presses the upper die core; the upper die fixing ring presses the upper die core sleeve and is fixedly arranged on the upper die fixed seat through screws; the lower die consists of a lower die core, a lower die core sleeve, a lower die core inner sleeve and a lower die core outer sleeve; the lower die core is plugged in the lower die core sleeve; the lower die core sleeve is plugged in the lower die core inner sleeve; the lower die core inner sleeve is plugged in the lower die core outer sleeve; a guide sleeve presses the lower die core outer sleeve and is fixedly arranged on the lower die fixed seat through guide sleeve screws; and the internal diameter of the guide sleeve is slightly greater than the external diameter of the front part of the upper die core sleeve of the upper die. The one-time forging mold can guarantee that no eccentric phenomenon is caused to the upper die core and the lower die core, so that the quality of the formed bicycle bearing is guaranteed.
Description
Technical field:
The present invention relates to the bicycle hub production technical field, a used forging mold when forging more specifically to a kind of bicycle hub.
Background technology:
Existing bicycle hub generally adopts forging mold and secondary forging mold forging molding in process of production, and forging mold mainly is to see shown in Figure 1 at the floral disc A(that workpiece forges colored hub).Its weak point is: an existing forging mold is in the punch ram process, and upper mold core and lower mold core are easily eccentric, cause the bicycle hub that forms out to become substandard products.
Summary of the invention:
Purpose of the present invention is exactly the deficiency at prior art, and provides a kind of bicycle hub a forging mold, and it can guarantee that upper mold core and lower mold core do not produce eccentric phenomena, thereby guarantees the quality of the bicycle hub that forms out.
Technology solution of the present invention is as follows:
Forging mold of bicycle hub, comprise model fixing seat, upper die and lower die and following model fixing seat, last model fixing seat is fixed on the jumper bar of punch press, following model fixing seat is fixed on the workbench of punch press, patrix is made up of upper mold core, patrix core retainer plate, compression leg and patrix retainer plate, the upper mold core sleeve is in the patrix core retainer plate, and compression leg is being pressed upper mold core, and the patrix retainer plate is being pressed the patrix core retainer plate and is being fixed on the model fixing seat by screw;
Counterdie is made up of cover and lower mold core overcoat in lower mold core, counterdie core retainer plate, the lower mold core, the lower mold core sleeve is in the counterdie core retainer plate, during counterdie core retainer plate sleeve overlaps in lower mold core, the cover sleeve is in the lower mold core overcoat in the lower mold core, the guiding casing pressure the lower mold core overcoat and is fixed on down on the model fixing seat by the fairlead screw, and the internal diameter of fairlead is slightly larger than the external diameter of front portion of the patrix core retainer plate of patrix.
Described fairlead screw sleeve is in the default hole of fairlead and lower mold core overcoat.
Beneficial effect of the present invention is:
It can guarantee that upper mold core and lower mold core do not produce eccentric phenomena, thereby guarantees the quality of the bicycle hub that forms out.
Description of drawings:
Fig. 1 is the structural representation of existing cycle hub
Fig. 2 is structural representation of the present invention
Fig. 3 is the decomposing schematic representation of analysing and observe of the present invention
Fig. 4 is perspective exploded view of the present invention
Among the figure: 1, go up model fixing seat; 2, patrix; 3, fairlead; 4, counterdie; 5, following model fixing seat; 6, workpiece; 7, folder workpiece cover; 8, fairlead screw.
The specific embodiment:
Embodiment: see shown in Fig. 2 to 4, forging mold of bicycle hub, comprise model fixing seat 1, patrix 2, counterdie 4 and following model fixing seat 5, last model fixing seat 1 is fixed on the jumper bar of punch press, following model fixing seat 5 is fixed on the workbench of punch press, patrix 2 is made up of upper mold core 21, patrix core retainer plate 22, compression leg 23 and patrix retainer plate 24, upper mold core 21 sleeves are in patrix core retainer plate 22, compression leg 23 is being pressed upper mold core 21, and patrix retainer plate 24 is being pressed patrix core retainer plate 22 and is being fixed on the model fixing seat 1 by screw;
Counterdie 4 is made up of cover 43 and lower mold core overcoat 44 in lower mold core 41, counterdie core retainer plate 42, the lower mold core, lower mold core 41 sleeves are in counterdie core retainer plate 42, counterdie core retainer plate 42 sleeves overlap in 43 in lower mold core, cover 43 sleeves are in lower mold core overcoat 44 in the lower mold core, fairlead 3 is being pressed lower mold core overcoat 44 and is being fixed on down on the model fixing seat 5 by fairlead screw 8, and the internal diameter of fairlead 3 is slightly larger than the external diameter of front portion of the patrix core retainer plate 22 of patrix 2.
Described fairlead screw 8 sleeves are in the default hole of fairlead 3 and lower mold core overcoat 44.
Operation principle: see shown in Fig. 2 to 4, workpiece 6 is placed in the folder workpiece cover 7 and places on the counterdie 4, patrix 2 is to be fixed on the jumper bar of art then, patrix 2 cooperates the last floral disc that stamps out cycle hub with counterdie 4, when punching press, allow patrix core retainer plate 22 go to cooperate with counterdie 4 along fairlead 3, can avoid upper mold core 21 and lower mold core 41 different axial lines like this, thereby the bicycle hub of avoiding producing becomes substandard products because concentricity is bad.
