In above-mentioned multifunction hydraulic revolved die, described thimble assembly comprised regulating shaft and the thimble head that is fixedly connected with regulating shaft one end.
In above-mentioned multifunction hydraulic revolved die, described thimble head adopted iron and steel or nylon or elastomeric material to make.
In above-mentioned multifunction hydraulic revolved die, described thimble assembly comprised the regulating shaft that adopts iron and steel to make.The regulating shaft of ferrous materials is in order to strengthen the intensity of regulating shaft.
In above-mentioned multifunction hydraulic revolved die, described demountable structure comprised the screw thread that is positioned at regulating shaft the other end, was threaded connection between described regulating shaft and connecting axle, was connected with locking nut on described regulating shaft.Regulating shaft can disassemble from connecting axle, changes the different regulating shaft of length to meet the demand of workpiece to be processed; Also can rotate regulating shaft and change the active length of self, then make regulating shaft relative with bearing block fixing with locking nut.
In above-mentioned multifunction hydraulic revolved die, described demountable structure comprised the Plug Division that is positioned at the regulating shaft other end, had spliced eye on described connecting axle, and described Plug Division and spliced eye are complementary.Regulating shaft directly inserts in the spliced eye of connecting axle, convenience quick for installation.
In above-mentioned multifunction hydraulic revolved die, described elastic construction comprised the bearing block between connecting axle and sleeve; One end of described bearing block penetrates sleeve, and described sleeve is provided with the limit journey part for restrictive axes bearing sliding stroke; Be provided with the spring that makes bearing block have outside tendency toward sliding in described sleeve; Be connected by bearing between described connecting axle and bearing block.Spring makes bearing block have downtrend, and connecting axle is connected with bearing block, and after connecting axle descends, drive thimble assembly and workpiece lean, and bearing block continues the decline rear spring and is squeezed, and workpiece can firmly be axially fixed.
In above-mentioned multifunction hydraulic revolved die, described elastic construction comprised the bearing block between connecting axle and sleeve; Be connected by bearing between described bearing block and sleeve; Described bearing sleeve is located on connecting axle, and described bearing block is provided with the limit journey part for restriction connecting axle sliding stroke; Be provided with the spring that makes connecting axle have outside tendency toward sliding in described bearing block.Spring makes connecting axle have downtrend, and connecting axle drive thimble assembly descends rear and workpiece leans, and connecting axle continues the decline rear spring and is squeezed, and workpiece can firmly be axially fixed.
Compared with prior art, this hydraulic swing die has the following advantages:
1. being connected to of push rod component and bearing block or connecting axle removably connects, easy installation and removal; Regulating shaft is threaded, and the rotation regulating shaft can be regulated the active length of self, changes the working range of thimble head, regulates more convenient.
2. bearing and roller use matched in clearance, and be more quick and convenient when changing different roller.
