Abstract
The invention discloses a pre-pressure oil cylinder positioning device used in fast-growing wood recombined bamboo-wood forming equipment, and relates to wood processing hydraulic equipment. The pre-pressure oil cylinder positioning device comprises a plurality of hydraulic oil cylinders, a pressing plate, an oil cylinder positioning device and a hydraulic system, wherein the plurality of hydraulic oil cylinders adopt identical structures, are arranged in the same height, are respectively provided with lower piston rods and upper piston rods; limiting cushion blocks are arranged at the tops of cylinder covers; limiting adjusting screw nuts are arranged at the upper ends of the upper piston rods; the distances between the upper surfaces of the limiting cushion blocks and the lower surfaces of the limiting screw nuts are equal. The pre-pressure oil cylinder positioning device has the benefits that due to the mechanical limiting and positioning device, when the upper piston rod adjusting screw nut on one hydraulic oil cylinder is in contact with the lower cushion block of the hydraulic oil cylinder, the oil cylinder stops pressing downwards and is kept be in a pressure retention state, and other oil cylinders continuously press downwards when oil is filled. When the adjusting screw nuts of all oil cylinders are in contact with the lower cushion blocks of the oil cylinders, the plurality of oil cylinders stop pressurizing and are in a 'continuous pressure and equal level' state, so that the pressing plate is in a horizontal state finally, compressed recombined wood is formed in equal thickness, the equal-density pressing quality is approached, the technical requirements are met, and the quality is good.
Description
Technical field:
The present invention relates to timber processing hydraulic technical equipment, particularly fast-growing woods Scrimber equal thickness gives the positioner of press forming device.
Background technology:
In the compressing process of fast-growing woods Scrimber.Because charging process can not accomplish that die cavity is feeded how many completely equal everywhere, so, adopt during horizontal pressure foot compacting and can not realize isodensity compacting., when feeding equilibrium as far as possible, be then realize product to suppress close to isodensity, make the effective way of the reality of requisite quality by the compacting of oil cylinder equal thickness.Take equal thickness to suppress when must accomplish that pressing plate is pressed onto a fixing limit height and locate stopping, to guarantee the consistency of thickness of forming material under die cavity clip plate.Crush board is pressed onto the spacing location of certain position, can take the method for photoelectric position limit, namely arranges photosignal generation device in equipment appropriate location, and when generation or the shading light signal of telecommunication, its hydraulic system quits work at once, reaches spacing, locates.But there is obvious defect in the method, its reason, one is that particularly each oil cylinder is noted, return line operating mode can not be definitely balanced because of hydraulic system, two is between piston and cylinder wall, between piston rod and cylinder cap, its seal degree, to produce hermetic resistance variant etc., all can cause producing piston rod, platen travel distance may be variant, thus cause final pressing plate not to be level, can slightly tilt.Such as take 3 hydraulic jack work systems, reason is analyzed because of above, each oil cylinder piston throw of lever there will be difference, if now first a certain photosignal generation device close at first has signal to export, then whole hydraulic system will quit work at once, and namely pressing plate keeps state this moment to stop, and now pressing plate not may be in level, and inclination may be there is, so, then necessarily thickness is not etc. for the compressing material of institute.So, take photoelectric position limit, locate the object not reaching equal thickness compacting.
Summary of the invention:
The object of the present invention is to provide a kind ofly gives compressing cylinder positioner for fast-growing woods Recombined bamboo wood former, employing mechanical position limitation is located, ensure final pressing plate level, realize equal thickness compacting, thus close to realizing isodensity compacting, not only appearance and size can be ensured but also substantially can ensure molded product density quality.
Technology contents of the present invention is, a kind of for fast-growing woods Recombined bamboo wood former give compressing cylinder positioner, comprise hydraulic jack, be loaded on the pressing plate of oil cylinder piston bottom, oil cylinder positioner and hydraulic system.Described positioner, comprises and is provided with multiple hydraulic jack, and multiple hydraulic jack structure is identical, and rational height is identical; Multiple hydraulic jack has upper piston rod, each hydraulic jack upper piston rod equal diameters; The cylinder cap top of multiple hydraulic jack is provided with limiting cushion block, and upper piston rod is provided with spacing adjusting nut through cylinder cap and its upper end of limiting cushion block, and each limiting cushion block upper surface is equal with the spacing of each stop nut lower surface.
The beneficial effect that the present invention produces:
The present invention takes mechanical position limitation, positioner, it comprises multiple hydraulic jack, there is upper piston rod and lower piston rod respectively, its cylinder cap top is provided with limiting cushion block, upper piston rod is provided with spacing adjusting nut through cylinder cap and its upper end of limiting cushion block, each limiting cushion block upper surface is equal with the spacing of each stop nut lower surface, and set its thickness of each limiting cushion block is equal.When a certain hydraulic jack upper piston rod adjusting nut contacts with its lower cushion block, namely this oil cylinder will stop oiling pressing down, place's packing state.Continuation oiling then presses down by other oil cylinder, when all its adjusting nuts of multiple oil cylinder all contact with its lower cushion block, multiple oil cylinder all stops pressing down work, so " continuous pressure is matched ", pressing plate is finally just in level, shaping by compression Scrimber equal thickness under it, reach technical requirement, quality is good.
Accompanying drawing illustrates:
The main apparent structure schematic diagram of accompanying drawing 1 the present invention
Detailed description of the invention:
Below in conjunction with Figure of description, according to provided a kind of detailed description of the invention, inventive principle is described further.
This gives compressing cylinder positioner for fast-growing woods Recombined bamboo wood former, comprises hydraulic jack 1, is loaded on the pressing plate 10 of cylinder piston rod bottom, oil cylinder positioner and hydraulic system.Hydraulic jack is provided with multiple, and the present embodiment is provided with 3, and 3 hydraulic jack structures are identical, and rational height is consistent.3 hydraulic jacks have upper piston rod 2 and lower piston rod 3 respectively.The cylinder cap top of hydraulic jack is provided with limiting cushion block 8, and upper piston rod 2 is provided with spacing adjusting nut 9 through cylinder cap and its upper end of limiting cushion block.Each limiting cushion block upper surface is equal with the spacing of each stop nut lower surface.
In present embodiment, its its thickness of each limiting cushion block is equal.
In above-mentioned embodiment, piston respectively has sealpiston-ring 7, and cylinder cap has sealing ring 18.
Its hydraulic system of the present invention comprises hydraulic elementary circuits, is made up of fuel tank, oil pump 13, check valve 14, overflow valve 15, three position four-way directional control valve 12 and oil pipe etc.The upper oil hole 5 of 3 hydraulic jacks connects four-way 16 through oil pipe, and the three position four-way directional control valve P of four-way 16 UNICOM hydraulic system passes in and out oilhole.Under 3 hydraulic jacks, oilhole 6 connects four-way 17 through oil pipe, 0 turnover oilhole of the three position four-way directional control valve of four-way 17 connecting fluid pressing system.
Before compacting, first should regulate positioning height, namely when pressing plate place level, regulate the distance between cushion block 8 and adjusting nut 9, make the cushion block upper surface of 3 oil cylinders equal with the distance between nut lower surface, and adjusting nut is locked.
