Description
Technical field
The invention belongs to stamping technology field.
Background technology
Stamping machine is that, by motor-driven flywheel, and by clutch, travelling gear drives the toggle to make cunning
Block moves up and down, and drives drawing die to steel plate forming.It is so-called it is double acting be exactly that finger pressure machine has two sliding blocks, be divided into inner slide
And outer slide, the punch-pin or cavity plate of inner slide driven mold, the blank holder on outer slide driven mold, in stretching, blank holder is first
Steel plate edge is pushed down in first action, and inner slide is reoperated and stretched.
The staking punch of general stamping machine is driven by hydraulic jack at present, general hydraulic jack be all by
Piston and cylinder body are constituted.Piston is acted under fluid pressure effect, is replied under fluid pressure or external force effect, so as to realize
The staking punch of stamping machine is moved up and down, and press work is carried out to workpiece, but general in piston Recovery Process, and piston is needed
Liquid in oil cylinder is discharged, when spill port is smaller or during oil return circuit more long, piston can be replied under the obstruction of liquid in oil cylinder
Speed is slow, cause piston can not Quick-return in place, cause the press work of whole stamping machine slowly, cause
The stamping forming efficiency reduction of workpiece, while when press work is carried out, workpiece surface can generate heat, if can not cool down in time,
The organization of inside workpiece can be caused to change, causing the quality of workpiece punching press reduces.
The content of the invention
It is an object of the invention to provide a kind of hydraulic jack for punching press, ram efficiency can be accelerated, improve punching press
Workpiece quality.
In order to achieve the above object, base case of the invention provides a kind of hydraulic jack for punching press, including cylinder body,
Cylinder body is provided with oil inlet and oil-out, and piston is provided with cylinder body, and piston one end is connected with First piston bar, and First piston bar is remote
Return mechanism is provided with from one end of piston, the piston other end is provided with drive rod, one end that drive rod is located at outside cylinder body is provided with the
One tooth bar, the first tooth bar is engaged with first gear, and the side of first gear is coaxially connected with second gear, and second gear is engaged with
Second tooth bar, the second tooth bar bottom is connected with the staking punch for punching press；Also include cooling cylinder, cooling cylinder is relative with drive rod,
Cooling cylinder side is provided with water inlet, and water inlet is provided with the first check valve；The opposite side of cooling cylinder is provided with delivery port, on delivery port
The second check valve is provided with, sparge pipe is connected with the second check valve, sparge pipe alignment stamped workpieces are provided with collection below stamped workpieces
Tank, is provided with suction pump in water leg, suction pump is connected with drinking-water pipe, and drinking-water pipe is connected with cooling away from one end of suction pump
Pond, cooling bay is provided with return duct, and return duct is connected with water inlet.
The principle of this base case is：When using, hydraulic pressure is subject to hydraulic oil, piston is poured in cylinder body by oil inlet
The thrust of oil starts movement, drive rod is moved in cooling cylinder, drives the first tooth bar to move together, first gear and the
One tooth bar is engaged, and drives second gear coaxially to be rotated, so as to drive the second tooth bar to move up and down, staking punch is started repeatedly
Press work is carried out to workpiece.
Drive shaft is gradually goed deep into inside cooling cylinder, while extruding the coolant in cooling cylinder, coolant is arranged from delivery port
Go out, coolant flows into sparge pipe, then from sparge pipe outflow, is sprinkling upon on workpiece, workpiece is cooled down, because workpiece is in punching press
Can be red-hot in journey, particularly need cooling in time during profound fire, therefore coolant after use can become awfully hot, then cool down
Liquid flows into water leg, and coolant is drawn back into cooling bay again by suction pump, and coolant recovers original temperature again.
After piston completes once extruding work, hydraulic oil is suctioned out into return mechanism simultaneously from oil-out and drives piston reset,
Drive rod is driven to be gradually backed out being produced in cooling cylinder, cooling cylinder negative pressure so as to coolant is passed through into return duct while piston reset
Again suck back cooling cylinder, be easy to it is next during recycle.
The beneficial effect of this base case is：In this programme in piston reset, piston is not only due to no longer receiving
Realize automatically reseting to the extruding of hydraulic oil, while be also that can accelerate piston reset in the presence of return mechanism, so that
Connecting cylinder can be promoted constantly to move back and forth, driving staking punch to move up and down carries out punching press to workpiece, improves punching press
The suction capactity of suction coolant in frequency and cooling cylinder, while punching press coordinates interval to implement with water spray, improves the punching press of workpiece
Quality.
Scheme two：Scheme is preferred based on this, and the cylinder body is provided with for stopping the fixed single of first piston axle offset
Unit.
Because the cylinder in the present apparatus is using horizontally disposed, then during long-term use, First piston bar is very
Easily there is skew, cause the air of outside to enter cylinder interior, cylinder interior is polluted, therefore fixed cell can have
The kinematic accuracy of the guarantee First piston bar of effect, is not in any skew.
Scheme three：This is preferred for scheme two, and the fixed cell includes being slidably connected at the support block of inboard wall of cylinder block, and
First piston bar surface fixed cover is enclosed within, support bar, support bar and fixed cover static connection are provided between fixed cover and support block.
Fixed cover it is possible to prevente effectively from First piston bar caused during long-term use abrasion, not only avoid first
There is skew in piston rod, can also improve the service life of First piston bar.
Scheme four：This is preferred for scheme three, and the cooling bay bottom is provided with magnetic sheet.
Due in punching course, it is likely that the waste material of iron filings etc can be produced at punching press, when coolant impact workpiece enters
During row cooling, coolant can mix with useless cutting, if not carrying out any treatment to such useless cutting, suck back cooling again like this
Cylinder, useless cutting just very likely is bonded on the wall of cooling cylinder, when drive rod is moved in cooling cylinder, can most probably damage driving
Bar.
Most of stamping parts is ferrous metal part simultaneously, therefore such useless cutting mixes with coolant, together into cold
But pond, the iron filings in cooling bay can just be adsorbed by magnetic sheet, and then reach the purpose of scrap iron removing.
Scheme five：This is preferred for scheme four, and the magnetic sheet is detachably connected in cooling bay.
Iron filings are attracted after magnetic sheet, you can take out magnetic sheet, iron filings are scraped and is reclaimed.
Scheme six：This is preferred for scheme five, and the return mechanism includes sliding block, is connected with crank on sliding block, crank with
First piston bar is connected.
Band movable slider movement when crank is rotated, crank is rotated one week, realizes that sliding block is constantly moved back and forth, and then driving the
One piston rod resets in time.
