Description

Quickly-advancing slowly-returning elastic colloid buffer
Technical field
It is single compressible semifluid macromolecular material that the utility model relates to the elastic colloid of filling in buffer, the especially buffer of the positive revesal different damping of a kind of piston type value.
Background technique
Currently be used on the general industry production line or the damping device of machinery adopts pneumatic type mostly; air fluid formula; hydraulic type; full fluid formula etc. is used for absorbing the impact energy between machinery; with protection equipment and reduction noise; the buffer of choosing which kind of form depends on endergonic size; the size of stroke, the mechanical structures form is for above-mentioned buffer; because the difference of the resisting medium that adopts; the buffer structure more complicated of commonly using is used and is installed, inconvenient maintenance; because a point load is than many problems such as the easy infringements of macrostructure; current industrial development form is particular about the quality of product, reliability of products, the working life of product and maintainability; this improves design to the damping device of commonly using as early as possible with regard to requiring us, to satisfy current operation technique requirement to buffer.
Summary of the invention
Be to provide a kind of after buffer is subjected to impulsive load according to the described the purpose of this utility model of background technique; buffer capacity absorbs most of Impact energy rapidly; effectively protected equipment; slowly stably reply then; avoid spring and protected equipment, effectively reduce a kind of quickly-advancing slowly-returning elastic colloid buffer of noise.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of quickly-advancing slowly-returning elastic colloid buffer, mainly by receiver (1), hold ram (2), piston (3), elastic colloid (4) and seal arrangement (5) are formed, wherein, the elastic colloid (4) of in holding the inner chamber (22) of ram (2), packing into, piston (3) is connected with piston rod (31), pack among the inner chamber (22) that holds ram (2), be connected in aggregatesly with holding ram (2) cylinder cap (21), be provided with unidirectional current-limiting apparatus (32) along piston (3) circumferential location, unidirectional current-limiting apparatus (32) is opened during compression stroke, unidirectional current-limiting apparatus (32) is closed during recovery stroke, leaves the gap between piston (3) external diameter and the inner chamber (22).
Owing to adopted technique scheme to the utlity model has following advantage and effect:
1, the utility model has adopted a kind of single high viscosity that has, special chemical inertness, and good thermostability, the elastic colloid of compressible semifluid macromolecular material has reached high damping, and it is big to absorb energy, the tangible purpose of cushioning effect.
2, the utility model can bear bigger impulsive load, holds the F.F. of raming and goes out slowly, automatically replies after external load is cancelled, and need not to set up resilient mounting, has effectively protected equipment and has reduced noise.
3, the utility model reasonable in design is easy for installation, does not have aging and leakage phenomenon, long service life, and maintenance and repair are simple and easy.

Among the figure: the 1-receiver, the 11-threaded block, 12-flange holder, 2-hold rams, 21-cylinder cap, 22-inner chamber, 3-piston, 31-piston rod, the unidirectional current-limiting apparatus of 32-, 4-elastic colloid, 5-seal arrangement
Embodiment
Illustrate by Fig. 1, the utility model is mainly by receiver 1, hold and ram 2, piston 3, elastic colloid 4 and seal arrangement 5 are formed, wherein, the elastic colloid 4 of in holding 2 the inner chamber 22 of raming, packing into, piston 3 is connected with piston rod 31, packs into and hold among 2 the inner chamber 22 of raming, with cylinder cap 21 with hold ram 2 be connected in aggregates, be provided with unidirectional current-limiting apparatus 32 along piston 3 circumferential location, unidirectional current-limiting apparatus 32 is opened during compression stroke, and unidirectional current-limiting apparatus 32 is closed during recovery stroke, leaves the gap between piston 3 external diameters and the inner chamber 22.
As can be known, the elastic colloid 4 that the utility model uses is single high viscosity, has special chemical inertness, good thermostability, and compressible semifluid macromolecular material, functional.
Illustrate by Fig. 2, working condition of the present utility model, when the utility model is subjected to external impact load F, holding rams 2 moves with F power is equidirectional, the elastic colloid 4 of filling in the inner chamber 22 is compressed (compression stroke or positive stroke), segment fluid flow flows to the A district by the gap between the 32 unidirectional apertures of opening of the unidirectional current-limiting apparatus on the piston 3 and inner chamber 22 and piston 3 external diameters, elastic colloid 4 absorbs most of impact energy when piston 3 and inner chamber 22 relative movement, simultaneously elastic colloid 4 is compressed when positive stroke and produces dynamic counter-force, after its bump stops under himself dynamic counter-force effect, holding rams 2 begins to reply (recovery stroke or revesal), because dynamically the aperture of unidirectional current-limiting apparatus 32 has been closed in the effect of counter-force, this moment, fluid can not be by the aperture of unidirectional current-limiting apparatus 32, fluid can only be mobile to the B district lentamente by the gap between inner chamber 22 and piston 3 external diameters, makes that holding rams 2 is returned to reset condition at leisure.Be provided with seal arrangement 5 between piston rod 31 and the cylinder cap 21, to guarantee effective seal.
Fig. 3 A illustrates the flange mounting type 12 of receiver 1, in order to adapt to the needs that occasion is installed.
Fig. 3 B illustrates the screw thread mounting type 11 of receiver 1, in order to adapt to the concrete needs of installing.
