Said push rod comprises corresponding upper ejector pin and lower push rod, and lower push rod is fixed on down and ejects on the crossbeam; The movable floor of upper ejector pin top and hot pressing die is structure as a whole, and upper ejector pin is the T type, and T type end is stuck in the dies cavity after being stretched into by mold bottom, and T type end end face is parallel with the bottom surface of dies cavity.
The described a kind of demoulding ejecting mechanism that is used on the vertical hydraulic press of the utility model utilizes follower to be connected with drift, not influencing under the descending prerequisite with punching course of drift, accomplishes the knockout course to workpiece through the up drive push rod of drift; Its result has broken away from before the dependence of hydraulic press bottom demoulding oil jar, has reduced cost of investment; Reduce energy resource consumption, improved knockout course and demoulding quality, not only convenient later maintenance; Handling good, adjustability is high, and ejection stroke can be decided, ejecting force is controlled; Eject process stabilization, reliable, improved production efficiency greatly, guaranteed the processing needs of many products.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The central idea of the utility model is: lift in the process at the hydraulic press drift, the demoulding that utilizes follower drive push rod to accomplish the punch forming product ejects process, the demoulding and drift is lifted simultaneously accomplish, and simplifies knockout course, guarantees demoulding reliability.
Do further description below in conjunction with 1 pair of the utility model of accompanying drawing:
The described a kind of demoulding ejecting mechanism that is used on the vertical hydraulic press of the utility model comprises a follower and a push rod.Follower comprises pull bar 9, slide block 7, guide rail 3, ejects crossbeam 1, lower locking nut 4, upper locking nut 8 and push rod setscrew nut 6 down.Slide block 7 is a blocks, is fixed on the jumper bar of hydraulic press drift 10, and moves along with the stroke of drift 10 is upper and lower.Guide rail 3 is fixed on the inboard of hydraulic press two ends column, matches with guide rail 3 in slide block 7 two ends.Pull bar 9 is a cylinder; Pull bar 9 is symmetrically distributed in hydraulic press drift 10 both sides and passes slide block 7 and hydraulic press workbench 5 respectively; Workbench 5 is fixed on hydraulic press two heel posts; Pull bar 9 axially with axially the paralleling of hydraulic press drift 10, the pull bar shaft can upper and lower slip in slide block 7 and hydraulic press workbench 5.Be fixed mandril; Under also being connected with between the bottom of two pull bars 9, eject crossbeam 1; For adjusting down the axial height that ejects crossbeam 1; On the pull bar 9 that ejects crossbeam 1 upper and lower end down, also be connected with lower locking nut 4 respectively, can make down the position that ejects crossbeam 1 upper and lower mobile through rotation lower locking nut 4.Receive the influence of drift 10 strokes and workpiece length; For guaranteeing that servomechanism process and push rod eject process reliably, effectively; Also be connected with upper locking nut 8 on pull bar 9 tops; Upper locking nut 8 bottom surfaces directly contact with slide block 7 tops when drift 10 is up, thereby can drive pull bar 9 and eject crossbeam 1 lifting down.And be to reduce pull bar 9 stroke descending with ejecting crossbeam 1 down, on the pull bar 9 between slide block 7 and the workbench 5, also be connected with push rod setscrew nut 6, through contacting of push rod setscrew nut 6 bottom surfaces and workbench 5 end faces, it is descending to limit pull bar 9.Push rod comprises separate and corresponding upper ejector pin 12 and lower push rod 2 two parts, and lower push rod 2 is fixed on down and ejects on the crossbeam 1, along with under eject the upper and lower together motion of crossbeam 1.Upper ejector pin 12 is a T type structure; Its position relative fixed; The T type end of upper ejector pin 12 is stuck in dies cavity after being stretched into by mould 11 bottoms, and parallels with the bottom surface of dies cavity, and T type end end face supports the bottom surface as the part of mould 11 and directly contacts with the bottom of workpiece to be punched.
Certainly, according to the difference of processing work, upper ejector pin 12 can directly not contact with workpiece to be punched yet; But the intracavity bottom of hot pressing die is made movable floor; Upper ejector pin 12 directly contacts with the bottom surface of movable floor when ejecting, thereby accomplishes the process that ejects of stamped workpieces.
During actual the use; At first according to the position of height adjustment upper locking nut 8, lower locking nut 4 and the push rod setscrew nut 6 of workpiece to be processed; Make down the upper and lower stroke that ejects crossbeam 1 and lower push rod 2 can not influence the installation and the process of workpiece, and can guarantee that stamped workpieces ejects smoothly.Detailed process is: when drift 10 is descending, and the influence of tension member 9 self gravitations, the bottom surface of upper locking nut 8 directly contacts with slide block 7 end faces, and drift 10 drives slide blocks 7 along guide rail 3 when descending, and pull bar 9 is also along with drift 10 is descending together.When the bottom surface of push rod setscrew nut 6 contacted with workbench 5 end faces, 6 pairs of pull bars of push rod setscrew nut 9 produced supporting role, and pull bar 9 stops descending, and at this moment, drift 10 continues descending along guide rail 3 and pull bar shaft, accomplishes the punching course to workpiece in the mould 11.When drift 10 is up; Along with the lifting of slide block 7, slide block 7 end faces can contact with the bottom surface of upper locking nut 8 once more, thereby it is up to drive pull bar 9; What be fixed on pull bar 9 bottoms ejects crossbeam 1 and lower push rod 2 is up down; Lower push rod 2 push card are lifted at the upper ejector pin 12 of dies cavity, and the T type end of upper ejector pin 12 is accomplished the demoulding of stamped workpieces and ejected a punching press---and knockout course is accomplished.So far, the vertical hydraulic press demoulding has been broken away from before the dependence of bottom oil cylinder, has simplified knockout course, has guaranteed demoulding quality.
