Abstract

PURPOSE:To provide an inexpensive and highly reliable titled apparatus by using an apparatus consisting od synchronized cylinders accompanied by kicker cylinders for accurately synchronizing rolling-down-cylinders which open and close forming rolls. CONSTITUTION:A rolling work is started in a closed state of forming rolls 1 and 1'; an working oil enclosed in a chamber (a) of each cylinder of the rolls is set to a low pressure by each relief valve 16. And when a material to be worked passes through the rolls 1 and 1', a high pressure is produced by the hydraulic oil enclosed to chamber (a). When the roll 1 is required to open rapidly while rolling, the pressure of a hydraulic pressure source is sent to a chamber (c) of a synchronizing cylinder 3 to move a piston by energizing solenoids B and E, thereby an oil in a chamber (d) is sent to chambers (b) of the rolling down cylinders 2 to actuate the roll 1 to the roll opening direction. At the same time, the oil in the chambers (a) is discharged to the side of a tank by energization solenoid valve 14. While the roll is stopped in an opened state, solenoids B and C are energized by a kicker cylinder 4 connected to the cylinder 3 to move a prston of the cylinder 3 further to the right side. Further, as a controlling of the rolls 1 and 1' is made to actuate bisymmetrically, the device at the right side in the figure is actuated in the same manner.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is based on a pressure
This relates to an I tension device.

In order to improve the yield of cast iron products made from fMk-rolled steel, improvements have recently been made to the specific gravity method. As one method, a method has been proposed in which the pressure fI shape in one direction is controlled by rapidly changing the pressure in the width direction of the sheet in the middle of the zero pressure.

The purpose of the present invention is to use a synchronized cylinder with a Kiraka cylinder as a high cylinder cylinder type device for opening and closing a long roll, and to provide a low-cost, small-sized crushing device. .

Figure 1 shows the hydraulic circuit of the present invention.

1.1' is a right pair of openwork rolls that press 4 parts of the material aC (pressure shield plate). 2.2' is a cylinder for the lower part of the arc-shaped roll, and it connects the forming roll 1.
Apply the required pressure to pressure 4 at 1'.

The J41 lever for press-smoking the material is fixed in position by driving this hydraulic/smoking rod with a screw feeder 4 using a screw feeder. (Not shown in this diagram) Good. ) A length with a pressure of 1 is not required because it is produced by the manufacturing scale of the pressure-blocking A product, so a special work of 44) is not required.

3.3' is 1'P m k of the reduction cylinder 2.2'
It is a 1st key cylinder that makes FJ A.

Figure 2 shows the resistance of Roll A.

The circuit diagram in FIG. 71 shows the cone closed and the rolling width set by a cylinder feeding device (not shown).

Since the dovetail roll operates on the left and right sides of the dtlAIi end, and is composed of circuits that perform the same fiber opening, only the ridge dilJ will be explained using the diagram.

The illustrated state JdA is the work of P2 figure, 3 and 3 figure in roll 1 man.
It is Nino in the original drawing, and at this time, cylinder 2's a storm and V'
) Low pressure oil set at -7ff16 is sealed. The rolling industry is I: A night, and the sword material is rolled.
, "l', the hydraulic oil in chamber a becomes pulp 13.
14, high pressure is generated as a pressure blocking reaction force. (15 is 41 V leaf that prevents high pressure: ff) Rolling shop [one piece that opens Pic roll i4 rapidly) V nodes B and E are dmm magnetic core, hydraulic source pressure is synchronized in 6.9τ ways / When υ1 is inserted into cylinder 3's cd and moved to 1st w4 cylinder piston 1t, the d imaginary oil passes through square 8, enters b4 of pressure 7 cylinder 2, and q-ru l is moved in the opening direction. The oil of e am to be operated is 14 4-sho lIJjJw&
By doing so, it is discharged to the field in the evening.

In the same A V ') cylinder, the working chambers are connected like a rock and the areas of the working chambers are made equal, so that the b of each reduction cylinder of the roll is equal. The amount of oil entering i1 is completely imaginary and decreases so that both rolls move φ- in perfect synchronization. (Picture 2-
The amount discharged from this -threat jλ and the amount flowing into chamber b are equal. Low AI close engagement is solenoid A
If υk uJJ + m, the hydraulic pressure is exceeded and υIL is applied to dJ, and the oil of Cλ enters ag and operates the roll in the opening direction, but the working surface of chamber a is the same as that of chamber b. 1
Because it is larger than tJR, the piston of one tuned cylinder is 4
In the case of Ji and close, the closing stroke of the roll becomes smaller when the roll moves to the bottom.
