Cylinder flange material jacking mechanism
Technical field
The utility model belongs to automobile die auxiliary equipment field, especially relates to cylinder flange material jacking mechanism.
Background technology
Main mechanical type flange backing-out punch and two kinds of modes of H type lifting jack used in existing technology.Wherein mechanical type flange backing-out punch exist fix actuation time, motion process determines by patrix completely, with the defect such as cylinder type flange backing mechanism can not exist simultaneously.The defects such as H type lifting jack, exists structure space large, easily rotates during work, and liftout is unstable.
Summary of the invention
Problem to be solved in the utility model is to provide cylinder flange material jacking mechanism, is especially applicable to the flange of the larger product of automobile and ejects work.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Cylinder flange material jacking mechanism, comprising: die ontology, cylinder, cylinder mounting flange, installing plate, die pad, and described cylinder is fixed on described cylinder mounting flange; The base of described cylinder mounting flange is fixed on described die ontology; The piston end surface of described cylinder is fixed on described installing plate lower surface; Described installing plate upper surface arranges described die pad.
Further, also comprise anti-bull stick, guide pin bushing, pressing plate, described guide pin bushing is arranged in the guide pin bushing installing hole of described die ontology; The fixed part of described pressing plate is fixed on the upper surface of described die ontology, and compressed part presses down the outward flange upper surface of described guide pin bushing; Described anti-bull stick is arranged in described guide pin bushing, and its upper surface is fixedly connected with the lower surface of described installing plate, under the drive of described installing plate, moves up and down.
Further, also wrap liftout portion, described liftout portion is arranged on described die pad front end, and described liftout portion shape is identical with the product shape that will eject.
Further, several slotted holes and two pin-and-holes are set on described die pad, by bolt, are connected with described installing plate with pin.
Further, described cylinder piston rod cross section is rhombus.
The advantage the utlity model has with good effect is: provide a kind of structure relative simple, compact, rationally, cost is low, can conveniently apply to the material jacking mechanism in automobile die flange liftout field.Independent agency is not subject to the impact of patrix motion, can control in real time liftout work, thereby can exist with cylinder type flange backing mechanism simultaneously by cylinder, the convenient product that takes out.

The specific embodiment
As shown in Figure 1, 2, the utility model cylinder flange material jacking mechanism comprises: die ontology 9, cylinder 7, cylinder mounting flange 6, installing plate 2, die pad 1, and described cylinder 7 is fixed on described cylinder mounting flange 6; The base of described cylinder mounting flange 6 is fixed on described die ontology 9; The piston end surface of described cylinder 7 is fixed on described installing plate 2 lower surfaces; Described installing plate 2 upper surfaces arrange described die pad 1.Also comprise anti-bull stick 3, guide pin bushing 4, pressing plate 5, described guide pin bushing 4 is arranged in the guide pin bushing installing hole of described die ontology 9; The fixed part of described pressing plate 5 is fixed on the upper surface of described die ontology 9, and compressed part presses down the outward flange upper surface of described guide pin bushing 4; Described anti-bull stick 3 is arranged in described guide pin bushing 4, and its upper surface is fixedly connected with the lower surface of described installing plate 2, under the drive of described installing plate 2, moves up and down.Also wrap liftout portion 11, described liftout portion 11 is arranged on described die pad 1 front end, and described liftout portion 11 shapes are identical with the product shape that will eject.Several slotted holes and two pin-and-holes are set on described die pad 1, by bolt, are connected with described installing plate 2 with pin.Described cylinder 7 piston rod cross sections are rhombus.
The course of work of this example: after product flange end-of-job, on any one time point after the rollback of part of the upper die.Open cylinder flange material jacking mechanism, Compressed Gas enters cylinder 7 by cylinder connector 8, and the piston rod on cylinder 7 drives on installing plate 2 and moves.On move past anti-bull stick 3 in journey and move with installing plate 2 one is the same, and under the guide effect of guide pin bushing 4, keep the stable of motion.In anti-bull stick 3 and piston rod common guarantee, moving past installing plate 2 in journey does not have position to rotate.Die pad 1 is mounted in the promotion of plate 2 and moves, and the liftout portion 11 of front end contacts and complete ejection process with the part that needs on product to eject after arriving liftout position.The position profile with ejected of the shape design of liftout portion 11 is consistent guarantees that in ejection process, this part of product is stressed evenly, completes smoothly ejection process.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
