Description
Technical field
The present invention relates to hydraulic press technical field, more particularly to a kind of punch structure of hydraulic forging press.
Background technology
With the rapid development of forging industry, the tonnage demand of the forging for hydraulic forging press is increasing, product
Required precision also more and more higher, for forging such as flanges, it is desirable to punching after base.It is special in ring forging hydraulic machine punch structure
It is not the 16 faces guiding hydraulic forging press hydraulic press for the requirement of big unbalance loading, punching precision and punching difficulty are higher, therefore, if
A kind of punch structure that disclosure satisfy that 16 faces guiding hydraulic forging press hydraulic press of meter exploitation seems it is particularly important.
The content of the invention
The technical problem to be solved in the present invention is：A kind of punch structure of hydraulic forging press is provided；The one kind forges hydraulic pressure
The punch structure of machine installs corresponding drift using quick change punch structure on slider of hydraulic press so that hydraulic forging press is special
When forging ring, for forging punching, and dnockout frame is set so that forging separates with drift after punching, reaches to forging
The purpose of punching.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
A kind of punch structure of hydraulic forging press, is comprised at least：
Slider of hydraulic press (1)；
The locking cylinder (2) of horizontal extension；
Flexible dnockout oil cylinder (3) vertically；
The drift (5) being placed on hydraulic press anvil block；
The locking drift (4) being installed on locking cylinder (2)；
And the knockout plate (6) of separation workpiece；Wherein：
The knockout plate (6) is installed on the piston-rod lower end of dnockout oil cylinder (3)；The shell and liquid of the locking cylinder (2)
Press slide (1) is fixedly connected；The shell of the dnockout oil cylinder (3) is fixedly connected with slider of hydraulic press (1).
Further：The hydraulic forging press is that 16 faces are oriented to hydraulic forging press hydraulic press.
The present invention has the advantages and positive effects of：
By using above-mentioned technical proposal, the patent utilization is arranged on the fixation drift on sliding block, improves punching forgings
Precision, and the fast quick-detach of hydraulic cylinder is utilized, all free forging process such as hydraulic forging press pulling are not influenceed, overcome traditional ring
Forging hydraulic machine can not carry out the defects of forged shaft such as pulling, core axial hole machining of flat-die forging.
The drift of the patent is directly installed on sliding block, and forging is punched out using hydraulic press active force, therefore the knot
Structure can use the face guide frame of free forging hydraulic machine 16, improve the use range of hydraulic press, meet hydraulic forging press pair
The requirement of unbalance loading operating mode.
Brief description of the drawings
Fig. 1 is the structure chart of the preferred embodiment of the present invention；
Wherein：1st, slider of hydraulic press；2nd, locking cylinder；3rd, dnockout oil cylinder；4th, drift is locked；5th, drift；6th, knockout plate.
Embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following examples, and coordinate accompanying drawing
Describe in detail as follows：
Referring to Fig. 1, a kind of punch structure of hydraulic forging press, including：
Slider of hydraulic press 1；
The locking cylinder 2 of horizontal extension；
Flexible dnockout oil cylinder 3 vertically；
The drift 5 being placed on hydraulic press anvil block；
The locking drift 4 being installed on locking cylinder 2；
And the knockout plate 6 of separation workpiece；Wherein：
The knockout plate 6 is installed on the piston-rod lower end of dnockout oil cylinder 3；The shell of the locking cylinder 2 is slided with hydraulic press
Block 1 is fixedly connected；The shell of the dnockout oil cylinder 3 is fixedly connected with slider of hydraulic press 1.
In above preferred embodiment：The hydraulic forging press is that 16 faces are oriented to hydraulic forging press hydraulic press.
In above preferred embodiment：After drift 5 is placed on hydraulic press anvil block, slider of hydraulic press 1 comes downwards to suitable position
Postpone, after drift 5 cooperates with locking drift 4, drive drift drift to position drift by locking cylinder 2, and be fixed on liquid
On press slide 1.Now hydraulic press is worked, and with the descending of slider of hydraulic press 1, forging is punched out.After punching, with liquid
Press slide 1 it is up, dnockout hydraulic cylinder 3 drives the enforcement workpiece of knockout plate 6 time to be separated with the whole stamping punch 5, reaches punching
Effect.
Embodiments of the invention are described in detail above, but the content is only presently preferred embodiments of the present invention,
It is not to be regarded as the practical range for limiting the present invention.Any changes and modifications in accordance with the scope of the present application,
All should still it belong within the patent covering scope of the present invention.
