Abstract
The utility model relates to a punching die for a clutch cover gear-rack hole, comprising an upper die frame, a lower die holder and a guide post which is connected with the upper die frame and the lower die holder. A convex die is arranged on the upper die frame, and a concave die is arranged on the lower die holder. The punching die for the clutch cover gear-rack hole is characterized in that the outer wall of the concave die is matched with a tight loop, and the blanking clearance is enlarged to 0. 8mm. The utility model can ensure the gear-rack hole of the clutch cover can be punched to form once in the punching die for the clutch cover gear-rack hole. The concave die can not be broken, and the intensity is high.
Description
(1) technical field: the utility model relates to machining mould class, particularly a kind of stamping die of clutch case rack bore of auto parts and components processing usefulness.
(2) background technology: the rack bore of CP structure clutch case is the drawing of branch two procedures in the prior art, main cause is that the die of mould has certain altitude, sidewall is thinner, once-forming, break easily in the existing mold processing, two procedures needs two molds like this, has increased manufacturing cost.
(3) summary of the invention: the purpose of this utility model is to overcome the crackly problem of existing mold, but a kind of stamping die of one-shot forming clutch case rack bore is provided.
Concrete scheme of the present utility model is the red tight loop of joining of die outer wall at existing clutch case rack bore stamping die, and strengthens the blade clearance and change and get 0.8mm (being 0.45-0.5mm originally).
The utility model intensity height simple in structure is difficult for breaking, and can guarantee a drawing of clutch case rack bore, reduces the mould number, has reduced operation, thereby has reduced manufacturing cost, and can increase the product size precision.
(4) description of drawings:
Accompanying drawing is a general structure front view of the present utility model.
Among the figure: 1-top mold frame, 2-punch, 3-guide pillar, 4-tight loop, 5-die shoe, 6-die.
(5) specific embodiment:
Referring to accompanying drawing, the utlity model has top mold frame 1 and die shoe 5, adopt guide pillar 3 to connect guiding top mold frame 1 and die shoe 5, punch 2 is housed on top mold frame 1, die 6 is housed on die shoe, and that adopts particularly that the 45# steel does a tight loop 4 and die 6 has promptly constituted the utility model red joining of outer wall.And the blade clearance is designed to 0.8mm.
Claims (1)
1. the stamping die of a clutch case rack bore includes top mold frame, die shoe, connects the guide pillar of top mold frame and die shoe, on top mold frame, adorn punch, die is housed on the die shoe, it is characterized in that being furnished with a tight loop in that the die outer wall is red, and the blade clearance is enlarged to 0.8mm.
