Description
Technical field
The present invention relates to the fine blanking die quick change construction of a kind of aerofluxus slab flange, it is applicable to produce material to be 3 be, 4 be the engine exhaust slab flange of rustless steel and ordinary carbon steel, it is also suitable all kinds of steel, copper material, the precise punching die of aluminium thin plate and multi-station transfer die punching press, is particularly suitable for engine exhaust slab flange punching press.
Background technology
Thick Plate Fine strategically important place is sought to the euphotic belt forming higher proportion, therefore the requirement of mould is higher, simultaneously that the maintenance of mould is more frequent, when design, punch is larger in size, can be reused by reconditioning punch after abrasion in use, production cost can be significantly reduced；And the mode that tradition uses bolt fixing needs two people when die change, and mould replacing time is longer；The quick die change technology grown up in developed country uses also gradually more and more at home, its die change speed can reach second level, but this technology is mainly overseas-funded enterprise or joint venture to be used, for avoiding the trouble of intellectual property, exploitation is suitable for our company and produces actual product, it is proposed that a kind of new structure.
Summary of the invention
The present invention seeks to convex model fixing seat condition and the fine blanking die quick change construction of a kind of aerofluxus slab flange is provided, upper mounted plate has groove, convex model fixing seat has upper and lower two grooves, it is respectively mounted lower jacking block and upper holder block, lower jacking block is connected by elastic lever connecting pin and lever, lever connects with upper holder block again, and lever has variable two fulcrum pin, when upper holder block needs to compress, to be in the arm of force of upper holder block side short for lever, when upper holder block needs to exit, when punch being ejected simultaneously, the arm of force that lever is in upper holder block side is long, concrete structure is by convex model fixing seat, upper holder block, lower jacking block, floating rod, return spring and lever resilient attachment pins structure division composition.
For achieving the above object, the present invention adopts following technical measures:
A kind of fine blanking die quick change construction of aerofluxus slab flange, it is characterized in that floating rod has two variable fulcrums, when clamping, to be in the arm of force of upper holder block side short for floating rod, when upper holder block needs to exit, when punch being ejected simultaneously, the arm of force that lever is in upper holder block side is long, so a people can complete when installation and removal, and mould replacing time is shorter.
The method is specific as follows:
1) installation of convex model fixing seat: on convex model fixing seat 3, design has bolt hole 16, use the fixing seat 3 of screw solid punch in the upper mounted plate bolt hole 6 of upper mounted plate 1, lever second fulcrum pin 22 of floating rod 15 is pressed into lever the first fulcrum pin-and-hole 18 simultaneously, installs return spring 17, upper holder block 4, lower jacking block 5, lever pressing plate 13 and lever connecting pin 20:
2) Fast Installation: upper holder block 4 has upper holder block taper seat 10, punch 2 upper-end contact is to upper holder block taper seat 10 when mounted, upper holder block 4 under return spring 17 and upper holder block taper seat 10 combined effect away from punch 2, when punch 2 upcoming contact is to the lower jacking block taper seat 11 of lower jacking block 5, lower jacking block 5 is away from punch 2, the transfer route of power presses punch 2 → lever connecting pin 20 → floating rod, 15 → brute spring, 26 → upper holder block, 4 → clamping plane, 25 → punch shoulder 9, complete upper holder block 4 to be pressed on punch 2 punch shoulder 9, complete Fast Installation；
