Description

The multi-cylinder sychronisation of lamination conveyer
Technical field: the utility model belongs to the part of appliance of lamination conveyer in the rigid foam battenboard tinuous production.A kind of multi-cylinder sychronisation of lamination conveyer particularly.
Background technology: the lamination conveyer is that a kind of to be used to produce upper and lower surface layer be hard plate material, and the centre is flame-retardant polyurethane, polyisocyanurate, phenolic foam sandwich sheet, rigid foam battenboard tinuous production special equipment.The multi-cylinder sychronisation promptly guarantees the steadily device of several working cylinder synchronous operations of up-down of all upper strata press that make the lamination conveyer.Existing lamination conveyer multi-cylinder sychronisation all is the synchronization loop devices that adopt multi-stage diffluence valve or flow divider-combiner to be combined into.There is following deficiency in actual use in this synchronization loop device of prior art:
1, can only guarantee the speed synchronization that the piston in each working cylinder rises or descends, and the physical location that the piston in each working cylinder of being unrealized rises or descends is synchronous.Its reason is to form each single multi-stage diffluence valve or flow divider-combiner of synchronization loop device, at first, in manufacture process, exists standard to allow, actual each different tolerance grade; Secondly, it is poor that the sealing property of each single multi-stage diffluence valve or flow divider-combiner also certainly exists; In addition, each single multi-stage diffluence valve or flow divider-combiner certainly exist and amplify shunting oil mass error step by step when combination is used in synchronization loop in pairs.Above-mentioned reason has caused this synchronization loop device of prior art; The shunting difference that when actual motion, occurs can not ignore; Divide the pressure that flows into each working cylinder also therefore to certainly exist than big-difference with oily flow; Its actual result is the speed synchronization that causes multi-cylinder piston to rise or descend, and the piston in each working cylinder rises or the physical location of decline and asynchronous.This has just caused the stability decreases of upper strata press in uphill process or decline process that relies on several working cylinder synchronous operations to go up and down, and if things go on like this, must shorten the service life of lamination conveyer.
2, can only apply in the working cylinder synchronous operation that sum is an even number, be that the synchronous operation of working cylinder of odd number is just powerless to sum.Its reason is multi-stage diffluence valve or a flow divider-combiner number of forming synchronization loop device when being even number, could form effective device loop of moving.This is restricted with regard to the design length that causes the lamination conveyer, can't satisfy user's actual needs.
This shows that it is synchronous to study and design a kind of physical location that can realize that the piston in each working cylinder rises or descend, the multi-cylinder sychronisation of the unrestricted lamination conveyer of working cylinder number is necessary.
The utility model content: the purpose of the utility model is that to overcome prior art be not enough; Research and to design a kind of physical location that can realize that the piston in each working cylinder rises or descend synchronous, the multi-cylinder sychronisation of the unrestricted lamination conveyer of working cylinder number.
The technical scheme that realizes the utility model purpose is: a kind of multi-cylinder sychronisation of lamination conveyer; Comprise main oil pump; Drive the main motor of main oil pump; Supporting main oil pump is arranged at the total check valve on the working connection, main overflow valve, pressure display table, main solenoid valve; Be communicated in several working cylinders of main solenoid valve through main hydraulic control one-way valve, the working cylinder piston lower inner cavity is by on the working connection of auxiliary oil circuit before secondary check valve, secondary overflow valve, secondary magnetic valve are communicated in total check valve, it is characterized in that main solenoid valve is communicated in the main oil cylinder piston lower inner cavity through hydraulic control one-way valve synchronously; Every working cylinder piston cavity of resorption is communicated with a corresponding synchronized cylinder by synchronous oil circuit; Every synchronized cylinder with the master cylinder be the center arranged radially around master cylinder, the piston rod end of every synchronized cylinder and main oil cylinder piston boom end are linked on the same circular connecting plate by securing member.
The purpose of the utility model can also adopt following further technical measures to realize:
In described several the working cylinders, the number of elements of working cylinder is the concrete number of elements that 4-28 merely hits and chooses.The technique effect of this design is the requirement according to the user; The needs of lamination conveyer entire machine design; The number of elements of working cylinder not only can be chosen to be 4,6,8,10,12,14,16,18,20,22,24,26,28, also can be chosen to be 5,7,9,11,13,15,17,19,21,23,25,27.
Described several working cylinders that are communicated in main solenoid valve through main hydraulic control one-way valve are meant: be communicated in inner chamber on the piston of several working cylinders of main solenoid valve.Described synchronous oil circuit is communicated with in the corresponding synchronized cylinder, and synchronously oil circuit both had been communicated in inner chamber on the piston of synchronized cylinder, also is communicated in the piston lower inner cavity of synchronized cylinder.The tailpiece of the piston rod of described several working cylinders all is fixed on the upper strata press body of lamination conveyer.The technique effect of above-mentioned three designs is in the course of the work, when main oil pump inputs to master cylinder with hydraulic oil, promotes connecting plate and drive synchronized cylinder to promote, and the piston of synchronized cylinder is failed oil and is pressed onto working cylinder at this moment, and the piston rod of working cylinder is promoted.Because the tailpiece of the piston rod of working cylinder is fixed on the press body of upper strata; Thereby the ascending motion of completion upper strata press; When the master cylinder off-load, hydraulic oil gets into the working cylinder epicoele, and working cylinder is descended; Hydraulic oil in the working cylinder cavity of resorption is back to synchronized cylinder and drives connecting plate and the decline of main oil cylinder piston bar, returns to original position.
The described synchronized cylinder that is the center arranged radially with the master cylinder around master cylinder, be adopt only single, or 2 or 3 synchronized cylinders shared same piston rod that superposes up and down, its end and main oil cylinder piston boom end are linked in same circular connecting plate by securing member.The technique effect of this design is under the constant prerequisite of result of use, makes compact conformation between master cylinder, synchronized cylinder, the connecting plate as much as possible, reduces manufacturing cost.
The multi-cylinder sychronisation of the lamination conveyer that the utility model enforcement obtains through on probation, has compared with prior art shown following beneficial effect:
1, realizes that piston rising in each working cylinder or the physical location that descends are synchronous.Adopt each synchronized cylinder piston rod to be fixed as one through the piston rod of connecting plate and master cylinder; Use a master cylinder to force to drive piston rising corresponding to several synchronized cylinders of several working cylinders; Because every working cylinder piston cavity of resorption is communicated with a corresponding synchronized cylinder by synchronous oil circuit; And the rising of the piston of every synchronized cylinder will be pressed into hydraulic oil the piston lower inner cavity of a corresponding synchronized cylinder through synchronous oil circuit; Force the piston physical location of synchronized cylinder to rise synchronously, the tailpiece of the piston rod owing to described several working cylinders all is fixed on the upper strata press body of lamination conveyer again, thereby has obtained the effect that upper strata press body rises thereupon.After the ascending motion of accomplishing the upper strata press; When the master cylinder off-load, hydraulic oil gets into inner chamber on each working cylinder piston through synchronous hydraulic control one-way valve-main hydraulic control one-way valve, and working cylinder piston is descended; The hydraulic oil of working cylinder piston lower inner cavity is back to inner chamber on the synchronized cylinder piston; So force working cylinder piston to descend, force drive main oil cylinder piston bar to descend through driving connecting plate, return to the home position before rising.Whole multi-cylinder sychronisation does not adopt the multi-stage diffluence valve or the flow divider-combiner of prior art; Also just avoided because of the piston physical location of each synchronized cylinder that the tolerance grade of each multi-stage diffluence valve or flow divider-combiner is different, sealing property difference causes asynchronous; The equipment damage of further having avoided upper strata press uphill process instability to cause has compared with prior art also just played the beneficial effect that prolongs the service life of lamination conveyer.
2, the working cylinder number is not restricted because of the operation of multi-cylinder sychronisation.The multi-cylinder sychronisation that prior art adopts multi-stage diffluence valve or flow divider-combiner to be combined into because of the operation of flow divider or flow divider-combiner must be to satisfy the condition that the working cylinder number is an even number, is that the synchronous operation of working cylinder of odd number is just powerless to sum.And every synchronized cylinder of the utility model employing is that the center arranged radially is around master cylinder with the master cylinder; The piston rod end of every synchronized cylinder and main oil cylinder piston boom end are linked in same technical scheme on the circular connecting plate by securing member, need not obviously in the enforcement to consider that the working cylinder number is the problem of even number.As long as the user has demand,, can select the 4-28 that comprises odd number arbitrary concrete cylinder number of merely hitting according to the needs of lamination conveyer entire machine design; In addition, be to be connected between synchronized cylinder and the working cylinder through synchronous oil circuit, as long as the user has demand, according to the needs of lamination conveyer entire machine design, the high-pressure oil pipe that can select Len req for use is as oil circuit synchronously.This just makes and adopts the lamination conveyer of the multi-cylinder sychronisation that the utility model implements to obtain to satisfy user's needs better; Improved the market competitiveness of complete machine, obtained the coml success more easily than the lamination conveyer that still adopts prior art multi-cylinder sychronisation.
