Abstract
The present invention relates to a technology for compressing or further compressing a rubber barrel according to a hydraulic principle. Due to technology limitation, the compression rate of the rubber barrel in the existing vibration isolator is generally less than 25%, and the vibration isolation effect and the sound attenuation effect are not ideal. The technology of the present invention is carried out in a working cylinder with a sealed cavity. An overflow valve in a hydraulic apparatus outside the sealed cavity regulates and controls the magnitude of hydraulic pressure. The technology for compressing rubber is completed by mechanical extrusion and auxiliary hydraulic pressure. The prepared rubber vibration isolator with a high compression rate of 25% to 65% can be widely used for the industries of railway vehicles, mining machinery, etc., effectively have vibration isolation effect and sound attenuation effect, enlarge application ranges and prolong service life.
Description
The invention relates to and use hydraulic principle and carry out and strengthens the relevant technology that rubber parts is pushed.
Rubber vibration isolator is widely used in industries such as railway locomotive, mining machinery, ordnance and is used for that power is reversed, vibration damper, plays vibration isolation and reduces the effect of noise.Tradition manufacture method commonly used is, the interlayer of inside and outside metal cylinder given processings (sandblast, go up adhesive) back implement the sulfuration of rubber is processed.Because after the sulfuration cooling, rubber is inner to produce bigger residual stress, has reduced Adhesion force, the vibration isolator of preparation (its rubber parts is not compressed), and the narrow and weak effect of using scope, life-span are short.Existing improving one's methods is now, adopt mechanical suit extrusion process, on the metal cylinder, the pressure outside that applies is by the guiding cover of metal cylinder and lower end tipping thereof in promptly being contained in the rubber sleeve after the sulfuration, rubber tube is pressed in the interlayer of inside and outside metal cylinder, makes vibration isolator.But when adopting the method, the pressure outside that applies delimits above one or the rubber barrel surpasses certain thickness, tend to because the shearing force that metalwork produces causes the distortion to rubber tube, even cracking, rubber tube moves down with external force, is difficult for making rubber tube to reach giving on the fixed position in interior metal cylinder, be difficult to meet or exceed rubber compressibility 25%, vibration isolator vibration isolation, the erasure effect of preparation are still undesirable, and have the shortcoming that working life is short, consumption is big, have limited it and have enlarged application area.The object of the present invention is to provide a kind of prior art also to fail the moulding technology of rubber compressibility between 25%～65% that reaches, produce more efficient useful tubular rubber vibration isolator.The vibration isolator that described technology is produced, owing to increased the frictional force of rubber tube in inside and outside metal cylinder interlayer, can more effectively bear the collision of axial force, radial force and universal joint power, improved vibration isolation erasure effect, effect to dither is better, has enlarged application area and has prolonged working life.
Description of drawings:
Fig. 1, Fig. 2, Fig. 3 are the main tool views before the technology, and Fig. 4 is the main tool component figure (being vibration isolator) after the technology.Fig. 5 implements tooling drawing of the present invention and hydraulic pressure installation figure.Said rubber compressibility is meant that the rubber tube decrement accounts for by the ratio of rubber tube thickness before pressing.As Fig. 2, shown in Figure 4, i.e. (h
O-h1)/(h
O) * 100%.
Working of an invention:
Manufacturing process of the present invention is carried out in the hydraulic cylinder of the closed chamber (10) of a band hydraulic pressure installation (16).Accessory-be subjected to gland (9), guiding clamping sleeve (5), guiding stuffing box gland (4), setting sleeve (7), housing pin (6) and hydraulic cylinder (8) etc. to help and quicken manufacturing process, main tool-outer metal cylinder (2), rubber tube (1), interior metal cylinder (3) are pressed after technology finishes and are combined into tubular rubber vibration isolator (Fig. 4).Between each member of closed chamber (10), all be equipped with rubber seal (11), (12), (13), (14), to play better sealing and pressurization.The pressure that adds (P) is applied pressure to by an ordinary press and is subjected to gland (9), after passing to the guiding stuffing box gland (4) of outer metal cylinder (2) and lower end thereof tipping, a formation closed chamber (10) between hydraulic cylinder (8) and setting sleeve (7), interior metal cylinder (3), rubber tube (1), guiding stuffing box gland (4).When pressure outside (P) overcame Volume Changes that frictional force between rubber tube (1) deformation force and rubber tube (1) and the interior metal cylinder (3) descends guiding stuffing box gland (4) to be risen greater than rubber tube (1) Volume Changes that compressive deformation rose, generation also increased hydraulic coupling gradually in the closed chamber (10).Along with the increase of rubber tube (1) deformation force and frictional force, the also corresponding increase of pressure outside (P) causes guiding stuffing box gland (4) and continues descendingly, and hydraulic coupling constantly raises.The effect of hydraulic coupling is, the pressure official post rubber tube (1) of itself and rubber tube (1) top interlayer is accelerated deformation and is entered inside and outside metal cylinder (3,2) interlayer, avoid guiding of the damage of the shearing force of stuffing box gland metal constructions such as (4) generation to rubber tube (1), along with guiding stuffing box gland (4) descends and the hydraulic coupling that increases gradually, hold and fixedly rubber tube (1) on the certain position of interior metal cylinder (3).Guiding stuffing box gland (4) reaches the pressurization that hydraulic coupling rose of the extruding of rubber tube (1) and generation and has increased decrement to rubber tube (1), has improved its compressibility.For avoiding guiding the destruction of stuffing box gland (4) the continuation hydraulic coupling that decline is increased rapidly, outside closed chamber (10), connect relief valve (15) control hydraulic coupling in the hydraulic pressure installation (16) to member.When hydraulic coupling surpasses certain value, relief valve (15) earial drainage, limit the peak of the interior hydraulic coupling of closed chamber (10), relief valve (15) institute definite value height, the interior hydraulic coupling of closed chamber (10) is appreciated fast, pressurization is obvious, and this press machine (pressure outside P source) piston cylinder area and the closed chamber (10) of acting on is when area ratio is big, and effect is more remarkable.Hydraulic pressure installation (16) has the function of drainage after fluid injection before technology, the technology, forms the Seal cage (10) and the favourable vibration isolator (Fig. 4) of taking and preparing of full of liquid.
The tubular rubber vibration isolator for preparing different compressibilitys is certain thicknessly pressed rubber tube to reach by choosing.
