Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further detail, and provides detailed description of the invention.
As it is shown in figure 1, this utility model one automobile hub bearing lightening hole punching die, it is applied to the forging stamping-out of lightening hole on automobile two three generations's hub bearing blank, reduces manufacturing procedure, reduce processing cost, improves the core competitiveness of enterprise.
nullConcrete structure includes product die 1 and upper mold 2，Product is positioned on product die 1，Upper mold includes upper mold gland 3、With upper mold gland 3 with the use of upper mold locking gear 4、Knock-out mechanism、Punch mechanism、Detent mechanism、Cooling body，Detent mechanism includes flange locating piece 5、Upper mold adapter 6，Flange locating piece 5 is fixing with upper mold adapter 6 to be connected，Punch mechanism includes pierce punch 7、Upper punch headgear 8，The lower end of pierce punch 7 sequentially passes through upper mold adapter 6 and flange locating piece 5，The upper end of pierce punch 7 extend in upper punch headgear 8，Knock-out mechanism includes upper mold pull bar 9、Upper mold knockout rod 10、Unloading block 11 and discharge arm 12，The lower end of discharge arm 12 touches with unloading block 11，The lower end of upper mold pull bar 9 is fixing with upper mold adapter 6 to be connected，The upper end of upper mold pull bar 9 extend into interior and with upper mold knockout rod 10 the lower end of upper punch headgear 8 and touches，Cooling body includes plunger cooling pipe 13，It is provided with inlet channel on upper mold gland 3，The upper end of plunger cooling pipe 13 is connected with inlet channel，The water stream channel connected with plunger cooling pipe 13 lower end it is provided with on upper mold adapter 6 and flange locating piece 5.For realizing guiding and reducing friction, drift gasket ring 14, drift guide pad 15, ram block 16 is set gradually from top to bottom in upper punch headgear 8, in the upper end of upper punch headgear 8, knockout rod guide pad 17 is set, being provided with upper mold cushion block 18 between this knockout rod guide pad 17 and unloading block 11, upper mold knockout rod 10 sequentially passes through knockout rod and guides 17 pieces and upper mold cushion block 18.Wherein, between top and the top of upper mold cushion block 18 of upper mold knockout rod 10, leave space, for realizing the fixing of product, prevent deformation of products, product die 1 arranges flange limiting device 19.
