Abstract
The utility model discloses a kind of jumping-ups and bottom knockout to rush blind hole device, jumping-up can be carried out to forging simultaneously and rush blind hole operation, press ram including being mounted on press machine top, there is press bench below press ram, longitudinally disposed centre bore is equipped in the centre of press bench, being furnished in the centre bore can be along the low punch that centre bore up and down direction moves, the lower end of low punch is fixedly connected with the upper end of piston rod, it is fixedly connected with the lower end of the hydraulic cylinder of piston rod matching with the base of the press machine, hydraulic cylinder connects hydraulic control.Using the present apparatus can to compared with prior art, have the advantages that it is time saving and energy saving, improve working efficiency, without intermediate heating, save the energy.
Description
Technical field
The utility model relates to a kind of forging process device, especially a kind of jumping-up and bottom knockout rush blind hole device, mainly
Forging for bearing race is processed.
Background technique
Currently, then the forging processing of bearing race is placed on pressure that is, by the column blank heating of certain length including jumping-up
On machine worktable, the longitudinal center line of blank is had perpendicular to the upper plane of workbench using the formed punch punching press on press machine top
Certain temperature blank keeps its outer diameter thicker.It is transferred to next station after jumping-up, carries out rushing blind hole.Rushing blind hole later again will be non-porous
Part is cut off, and forms cricoid bearing race blank.For large-scale bearing race, it is moved to from a jumping-up station and rushes blind hole
Station is extremely difficult, time-consuming and laborious, its temperature is decreased obviously when blind hole station is rushed in arrival, causes to be not achieved and rush required by blind hole
Temperature, it is often necessary to additional heat.This mode not only time and effort consuming, working efficiency is low, and waste of energy.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, time saving and energy saving, the upsetting saved the energy, improve working efficiency
Thick and bottom knockout rushes blind hole device, overcome the deficiencies in the prior art.
The jumping-up and bottom knockout of the utility model rush blind hole device, the press ram including being mounted on press machine top,
There is press bench below press ram, be equipped with longitudinally disposed centre bore in the centre of press bench,
Being furnished in the centre bore can be along the low punch that centre bore up and down direction moves, the lower end of low punch and the upper end of piston rod
It is fixedly connected, is fixedly connected with the lower end of the hydraulic cylinder of piston rod matching with the base of the press machine, hydraulic cylinder connects hydraulic control
Mechanism processed.
The piston rod upper end is fixedly connected with the lower end of low punch by ring flange and bolt.
The jumping-up and bottom knockout of the utility model rush blind hole device, due to there is centre bore in the middle part of press bench,
In centre bore equipped with can the mobile low punch of up and down direction, be terminated under low punch driving low punch move up and down it is hydraulic
Cylinder when jumping-up, can be acted by hydraulic control driving hydraulic cylinder, made piston rod drive low punch mobile, made low punch
Blank after heating is placed on workbench to the position concordant with plane on workbench, utilizes press machine by upper end planar movement
Formed punch carries out punching press to blank, keeps blank diameter thicker, after jumping-up, in the state that blank temperature is kept, utilizes hydraulic control
Device driving hydraulic cylinder movement processed, moves up piston rod, low punch is punched out blank, can be under blank when low punch moves up
Punching press upwardly makes blank centre form blind hole.The jumping-up of blank passes through the present apparatus in a station with blind hole process is rushed
Upper disposable completion.Compared with prior art, it heated with time saving and energy saving, raising working efficiency, without centre, save the energy
Advantage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is the usage state diagram of the utility model.
Specific embodiment
As shown in Figure 1, 2: the jumping-up and bottom knockout of the utility model rush blind hole device, including being mounted on press machine top
There are press bench 4 in press ram 1, the lower section of press ram 1.
Longitudinally disposed centre bore is machined in the centre of press bench 4, being furnished in centre bore can be along center
The mobile low punch 3 of hole up and down direction.The lower end of low punch 3 is fixedly connected with the upper end of piston rod 5.Match with piston rod 5
The lower end of hydraulic cylinder 6 be fixedly connected with the base of press machine, hydraulic cylinder 6 connects hydraulic control.Hydraulic control can drive
Hydrodynamic cylinder pressure 6 acts, and by hydraulic cylinder 6 and drives 5 up and down direction of piston rod mobile, low punch 3 is therewith at the center of workbench 4
It is moved up and down in hole.
In order to facilitate disassembly, 5 upper end of piston rod can be fixedly connected with the lower end of low punch 3 by ring flange 7 and bolt 8.
The jumping-up and bottom knockout of the utility model rush blind hole device, due to having centre bore in the middle part of press bench 4,
In centre bore equipped with can the mobile low punch 3 of up and down direction, be terminated with the liquid that driving low punch 3 moves up and down under low punch 3
Cylinder pressure 6 when jumping-up, can be acted by hydraulic control driving hydraulic cylinder 6, make piston rod 5 drive low punch 3 mobile, under making
The upper end planar movement of the formed punch 3 extremely position concordant with plane on workbench 4, the blank 2 after heating is placed on workbench 4,
Punching press is carried out to blank 2 using press ram 1, keeps 2 diameter of blank thicker, after jumping-up, in the state that 2 temperature of blank is kept
Under, it is acted using hydraulic control device driving hydraulic cylinder 6, moves up piston rod 5, low punch 3 is punched out blank 2, undershoot
First 3 can make 2 centre of blank form blind hole (as shown in Figure 2) when moving up from the lower punching press upwardly of blank 2.The jumping-up of blank 2
By the present apparatus, the primary property on a station is completed with blind hole process is rushed.Compared with prior art, there is time saving and energy saving, raising
Working efficiency heats without centre, saves the advantages of energy.
