Abstract
The utility model discloses a two-way oil pressure buffer. The piston of the two-way oil pressure buffer is provided with an axial small hole which controls the speed of oil liquids which flow from one chamber to the other chamber, and stable buffering for stopping is realized. Two ends of the piston are separately provided with a piston rod; two-way buffering for stopping can be realized. The utility model has the advantages that the structure is simple, the buffering for stopping can be stably and reliably realized, and the seal is reliable. Sealing elements are arranged between the joint surfaces between the body of the oil cylinder and a cylinder cover, and the hole of cylinder cover and the piston rods.
Description
The utility model relates to a kind of oil buffer, is particularly useful for the bidirectional buffering stop of plastic cement slide fastener Jet forming machine chain belt holder.
The left and right sides of the chain belt holder of used plastic cement slide fastener Jet forming machine respectively is provided with a buffering retainer; When the chain belt holder when side is mobile, relies on the corresponding block that is provided with on its left side (or right) buffering retainer and the frame to realize buffering stop to the left side of frame (or right); The buffering retainer is driven by cylinder; Its shortcoming is that buffering stop is uneven steady, and the steam in the cylinder can't be got rid of fully in addition, often has water leakage, and makes humid environment, influences work.
The purpose of this utility model is to design a kind of two-way oil buffer for overcoming above-mentioned deficiency, and its piston is provided with axial aperture, and the axial aperture of fluid on piston cushioned stop stably; Be equipped with seal between cylinder body and cylinder cap, cylinder head bore and piston rod, sealing is reliable.
The utility model content, the piston both sides of two-way oil buffer respectively are provided with piston rod, and piston is provided with axial aperture, in the annular groove on the cylindrical of piston piston ring is housed; One in two piston rods is provided with axial hole, and it and inclined hole are formed oil filler point, and cushion pad is equipped with in the end of piston rod, and the end of cylinder body and cylinder cap are provided with O-ring seals therebetween by being threaded; The hole and the piston rod of cylinder cap match, and are provided with oil sealing therebetween.
The utility model advantage, the piston of two-way oil buffer is provided with axial aperture, when the chain strap clamp moves left, left block on the piston rod of bidirectional buffer left end and the frame bumps against, the axial aperture of the fluid of right cavity of cylinder on piston flows to the left chamber of oil cylinder, thereby make the chain belt holder be cushioned stop stably, two piston rods about piston of the present utility model is provided with have replaced existing two buffering retainers.
Description of drawings:
Fig. 1 is the utility model front view (analysing and observe)
Fig. 2 is for now using the buffering retainer schematic diagram of plastic cement slide fastener Jet forming machine
The utility model embodiment, the both sides of the piston 9 of two-way oil buffer respectively are provided with piston rod 11, and piston 9 is provided with axial aperture 13, and piston ring 7 is housed in the annular groove on the cylindrical of piston 9, one in two piston rods 11 is provided with axial hole 14, and it and inclined hole are formed oil filler point; Cushion pad 1 is equipped with in the end of piston rod 11, and cylinder body 6 ends and cylinder cap 3 are provided with O-ring seals 5 therebetween by being threaded, and the hole of cylinder cap 3 and piston rod 11 match, and are provided with oil sealing 4 therebetween; Two-way oil buffer is installed in the hole of centre of chain belt clipping base 8 of plastic cement slide fastener ejaculator, two ends are spacing by gland 10, the axial hole outer end of doing the piston rod 11 of axial hole is a stepped hole, steel ball 15 wherein is housed and is with externally threaded gland 2, the outer end also is installed with rubber buffer 1, when irritating oil, take off cushion pad 1, gland 2 and steel ball 15, fluid is through axial hole 14, inclined hole 12 flows to the right chamber of two-way oil buffer oil cylinder, after fluid is filled with, the steel ball 15 of packing into successively, screw gland 2 fluid closely is enclosed in the oil cylinder, and then load onto cushion pad 1.
