The specific embodiment
Existing embodiment with reference to accompanying drawing narration inventing type.
Like Fig. 1, shown in 3; A kind of Lifting Device; Comprise the device frame that constitutes by base plate 10 and top board 20; Be provided with telescopic material jacking mechanism 40 between base plate 10 and the top board 20, thimble 41 terminations that constitute material jacking mechanism 40 are in and extend top board 20 outsides and be the top and stretch two kinds of location status that position and retraction are the retraction position.Through an easy material jacking mechanism 40 is set between base plate 10 and top board 20; Thimble 41 terminations of material jacking mechanism 40 extend top board 20 outsides and are when stretch on the top and can stamping parts in top board 20 upper die be ejected; Use expensive cylinder top materials device that stamping parts in the mould is carried out liftout thereby replaced, the production cost of plate in reducing.
The adjustable bindiny mechanism of spacing 30 is set between described base plate 10 and the top board 20.Described material jacking mechanism 40 comprises the thimble 41 of shoring stamping parts, and described thimble 41 bottoms are connected to orders about thimble 41 and do the top and stretch the elastic component of motion.Through the elastic component that thimble 41 bottoms are provided with, elastic component is compressed the back and promotes thimble 41 and pass top board 20 and shore the stamping parts in its upper die.Compression that elastic component can be repeated or stretching, thereby the liftout when satisfying serialization and producing.When concrete operations; Can be according to the tightness degree of stamping parts clamping in mould; Spacing through bindiny mechanism 30 regulates between base plate 10 and the top board 20 ejects getting stamping parts in the mould in order to the decrement that increases or reduce elastic component, to obtain optimized effect.
Described bindiny mechanism 30 is made up of bolt 31; The bolt head of bolt 31 is arranged in the counterbore on the base plate 10; The thread segment 311 of bolt 31 is arranged in the connecting hole of offering on the top board 20 22, and the two ends of this connecting hole 22 are respectively equipped with nut 313,314 and are connected with this thread segment 311.Be provided with the pipe 312 of regulating top board 20 and base plate 10 spacings between described nut 313 and the connecting hole 22, pipe 312 is coated on the periphery wall of thread segment 311.Through bolt 31 top board 20 and base plate 10 are connected as a single entity; The elastic component that is installed in like this between top board 20 and the base plate 10 could well be compressed; After the elastic component compression finishes, will promote to push up 41 to the direction motion near top board 20, thimble 41 upper ends are passed top board 20 and are shored the stamping parts in the mould.When concrete operations, can regulate the spacing between top board 20 and the base plate 10 through the height that changes pipe 312, satisfy different demands of producing.
Described elastic component is a spring 42, and spring 42 lower ends are socketed on the axis of guide 43 and are resisted against on the upper face of base plate 10, and the lower end of the described axis of guide 43 is provided with a protuberance, and said base plate 10 middle parts are provided with the jack 11 that is complementary with protuberance.The upper end of spring 42 is set in the lower end of thimble 41 and is resisted against on the scene-affinity end face of thimble 41 stage casings setting.The axis of guide 43 and base plate 10 constitutes and is fixedly connected, and being connected of spring 42 and base plate 10 not only is convenient in the setting of the axis of guide 43, and the direction of motion of spring 42 is limited, make spring 42 at every turn the directions of motion of promotion thimbles 41 be consistent.
Described thimble 41 is a step axle shape; Its stage casing is larger-size scene-affinity; Last hypomere is respectively the less axle body of diameter; The upper end of spring 42 is set in the lower end of thimble 41 and is resisted against the scene-affinity that thimble 41 stage casings are provided with, and described top board 20 middle parts have the pilot hole 21 that is complementary with thimble 41 upper ends, and the upper end of thimble 41 can be free to slide in pilot hole 21 and thimble 41 can be shored the stamping parts in top board 20 upper die in its top when sliding into peak.The pilot hole of offering through the vestibule and top board 20 middle parts on thimble 41 lower ends and spring 42 tops 21 carries out clamping, and further the direction of motion to spring 42 and thimble 41 limits, and guarantees stability, the reliability of Lifting Device.
Described thimble 41 tops are connected to posterior limiting 412.Through on thimble 41 tops one protuberance 411 being set, described elastic layer 411 is connected on the protuberance 411.Thimble 41 is made up of rigid material, through the damage that elastic layer 412 avoids thimble 41 stamping parts to be caused when the liftout is set.
Described top board 20 is the identical circular plate bodys of two block sizes with base plate 10, and said bolt 31 is provided with four, is evenly arranged in the side face scope of top board 20 and base plate 10 plate faces.Counterbore shape connecting hole 22,12 through being provided with respectively with top board 20 and base plate 10 cooperatively interacts, and base plate 10, top board 20 and elastic component are connected as a single entity.Through top board 20 and base plate 10 are arranged to toroidal, practice thrift sheet material, reduce production cost.Whole machine balancing when equally distributed bolt 31 can keep Lifting Device to place.
In conjunction with Fig. 1,2,3; Earlier the bolt that configures 31 is connected with base plate 10 when mounted; The axis of guide 43 is connected in the base plate 10 middle part jacks 11, the lower end of spring 42 is socketed on the lead 43 again, is plugged on the lower end of thimble 41 upper end of spring 42 then; At last top board 20 is socketed in the upper end of the end of thread and the thimble 41 of bolt 31, the cooperation through bolt 31 and nut 314 is connected as a single entity base plate 10, top board 20, bindiny mechanism 30, material jacking mechanism 40.In use with the material jacking mechanism assembly be installed in diel under, mould moves downward and promotes top board 20 compression material jacking mechanisms 40, the springs 42 in the material jacking mechanism 40 are compressed; Thereby storage elasticity potential energy; When diel with after top board 20 separates, the elastic potential energy that spring 42 stores will discharge, and promotes thimble 41 and moves upward; The punching press plate in the mould will be shored in the upper end of thimble 41; After liftout finished, next mould can promote top board 20 compression material jacking mechanism 40, so repeatable operation again again.The present invention is simple in structure, easy to operate, maintenance is easy, the production cost of plate in can effectively reducing.
