Abstract
The utility model relates to a bi-directional hydraulic system for a wooden board splicing machine which is used for making wooden fibre boards under the heating and pressurizing condition, comprising a device for providing power source, a bidirectional hydraulic controller and a horizontal and a vertical pressurizing actuation devices. The utility model has the advantages of simple structure, easy operation, easy maintenance, big pressure and high work efficiency. As the wooden board splicing machines with the bi-directional hydraulic system can ensure the quality requirements of various gluing pressurization technologies, the utility model can satisfy the general requirements of the forest areas and the wood-processing factories of China to the hydraulic wooden board splicing machines.
Description
The utility model is about make the hydraulic system that jigsaw machines such as wood fibre plate are used under the pressurized conditions that is heated.
Make the jigsaw machine of wood fibre plate at present by the pressurization of being heated, its hydraulic system generally is the unidirectional hydraulic structure of the down pressurization or the pressurization that makes progress.This only different hydraulic structure on arranging is used for wooden jigsaw machine and has then often limited the kind development of processing wooden jigsaw.For example produce a kind of hardwood parquet flooring, the hydraulic structure of the various wooden jigsaw machine that uses just can't realize workpiece is carried out simultaneously the gluing technique requirement of level and vertical pressurization at present.
The purpose of this utility model is exactly to provide a kind of various gluing techniques that satisfy wooden jigsaw machine to add the bidirectional hydraulic system of pressure request, easy operating simple in structure maintenance at the problems referred to above.
The utility model is achieved in that fuel tank continues into the power source generator by filter and variable vane pump; Variable vane pump output and through the pressure oil of one-way valve, the bidirectional hydraulic control gear that supply is made of hand-operated direction valve and Pilot operated check valve; What move under the effect of bidirectional hydraulic control gear is by formed level of oil cylinder and pressure head and vertical pressurization actuating device.
Independent mutually by means of this pressurization device, as to be independent of each other hydraulic system, no matter that a kind of wooden jigsaw machine can both be suitable for; Owing to the power source unification provides, and adopt manually control, get final product smooth operation as long as Operation and Maintenance person possesses just shallow hydraulic transmission knowledge; Because of bidirection press can reach 20 tons respectively, therefore be used for the quality requirement that wooden jigsaw machine can guarantee all kinds of gummed pressing technologies on the other hand, satisfy China forest zone and each wood-working factory generally needs hydraulic puzzle machine.
The concrete device details and the working condition of this model utility are provided by following embodiment and accompanying drawing thereof.
Fig. 1: the bidirectional hydraulic system diagram of representing an embodiment of the present utility model.
Fig. 2: represent the stereochemical structure sketch that same embodiment's pressurization actuating device (31,32) fixedly links.
As shown in Figure 1, the bidirectional hydraulic system is made of with vertical pressurization actuating device (31,32) power source generator (4), bidirectional hydraulic control gear (10,28) and level.Power source generator (4) forms by fuel tank (2) and filter (3) are common based on variable vane pump (1), and its variable vane pump (1) direct connection has motor (5).Working oil in the fuel tank (2) is No. 20 machinery oil or a pressure oil, and through 100～200 purpose filter screens, the oil temperature generally should be below 55 ℃ during work when packing into.Behind motor (5) switch that starts variable vane pump (1), the pressure oil of variable vane pump (1) output can be supplied with bidirectional hydraulic control gear (10,28) through one-way valve (6).Be provided with the middle pressurized overflow valve (30) of protection variable vane pump (1) in the ingress of one-way valve (6); Be provided with pressure gauge (8) and pressure meter switch (7) in the outlet port of one-way valve (6).In before the work pressure of pressurized overflow valve (30) should be adjusted to pressure limiting pressure 63 kgfs that are lower than variable vane pump (1)/centimetre
2By opening pressure meter switch (7), pressure gauge (8) then indicate whether be lower than pressure limiting pressure 63 kgfs/centimetre
2In 3～5 minutes starting stage of start running, can reflect the running operating mode of variable vane pump (1) by middle pressurized overflow valve (30), if any phenomenons such as obstruction, then shutdown such as cleans at work; As work well, then can drop into normal use.Bidirectional hydraulic control gear (10,28) is made up of hand-operated direction valve (9,29) and Pilot operated check valve (11,27); Level then is made up of oil cylinder (15,16,23,25) and pressure head (19,20) with vertical pressurization actuating device (31,32).After coming into operation, at first vertically pressurization: promptly operate hand-operated direction valve (9), pressure oil enters the no bar epicoele (14,17) of oil cylinder (15,16) through hand-operated direction valve (9) and Pilot operated check valve (11), positive pressure head (19) is vertically depressed action and moderately is pressed on the processing object, and be in meta with hand-operated direction valve (9) this moment.Next carries out level and advances: promptly operate hand-operated direction valve (29), pressure oil enters the no bar of oil cylinder (23,25) through hand-operated direction valve (29) and Pilot operated check valve (27), tail chamber (22,26), after side pressure head (20) is made level and is advanced action to make processing object reach certain pressure, further operation of vertical pressurization oil cylinder (15,16) pressurization again.Variable vane pump (1) pressurize can further be started this moment by this bidirectional hydraulic system; Also can make hand-operated direction valve (9,29) be in meta and stop variable vane pump (1) pressurize in short-term.After the pressurization object is shaped, then can carry out the complete machine unloading.Hand-operated direction valve (29) pressure oil this moment of elder generation's operant level pressurization enters from the rod chamber (21,24) of cross cylinder (23,25), when input pressure reaches when being enough to breakdown Pilot operated check valve (27), rodless cavity (22, the 26) pressure oil of cross cylinder (23,25) flows back to fuel tank (2) through Pilot operated check valve (27) from hand-operated direction valve (29), the flat position of returning of side pressure head (20).Then can finish unloading by the aforesaid operations order to vertical oil cylinder (15,16).On vertical pressurization actuating device (32), be furnished with unidirectional sequence equilibrium valve (12), can prevent the decline accident generation of vertical oil cylinder (15,16) when unloading or after the unloading.Unidirectional sequence equilibrium valve (12) makes the input pressure of hydraulic fluid port enter rod chamber (13,18) and when being enough to open Pilot operated check valve (11), rodless cavity (14, the 17) pressure oil of its oil cylinder (15,16) promptly flows back to fuel tank from Pilot operated check valve (11) through hand-operated direction valve (9), positive pressure head (19) rising return.
Fig. 2: pressurization actuating device (31,32) is that crossbeam (33), bottom are worktable (35) by top, and the frame of the whole shaped as frame structure that is connect by four pillars (36) is fixed.Crossbeam (33) is equipped with the oil cylinder (15,16) of two vertical pressurizations, positive pressure head (19) is the rectangle stressed plate, two oil cylinders (15,16) are mechanically linked into an integrated entity, and so vertical pressurization device (32) just can be carried out compressing of Vertical direction and unclamp program under hydraulic pressure.Two oil cylinders (23,25) of level are fixed on the side seat (34) of horizontal plane of worktable (35), side pressure head (20) also is a rectangle stressed plate, mechanically link together with two oil cylinders (23,25) of level, but compressing of executive level direction unclamped program under hydraulic pressure.There is the bearing carrier board (37) of a correspondence on the line of action opposite of its side pressure head (20), in order to bear horizontal impacting force.
