Description

The piston structure of metal extrusion press oil hydraulic cylinder improves

Technical field

The piston structure that the utility model relates to a kind of metal extrusion press oil hydraulic cylinder improves, especially refer to a kind of as its piston of high tension oil hydraulic cylinder that reclaims scrap metal extruding usefulness, this piston is had disassemble maintenance and the advantage of installing easily, but and make the piston ring monolithic element do to damage replacement, reach the effect that maintenance cost is more saved.

Background technique

General employed Bottle ﹠ Can class packaging container in daily life, have that much have can recycling, and because of callable metal species Bottle ﹠ Can when being used as rubbish and being dropped, cause waste can't burn into the cause of ashes easily, and metal matter waste can not be decomposed by soil microorganism, buries processing so the metal species waste of class is not suitable as.Add present tellurian fossil energy exhaustion, thus reclaim waste hardware class rubbish in addition fusion to make new product again be the general practice.

For the waste hardware series products after reclaiming, general processing mode is all to be utilized metal extrusion press that the waste hardware series products is concentrated earlier afterwards to be pressed into specific square bulk, the carrying out that makes work such as making things convenient for the preceding transportation of smelting furnace fusion, storage.And mainly be provided with cylinder sleeve in the structure of metal extrusion press, primary component such as piston ring and piston rod, and be respectively equipped with oil inlet hole and oil outlet on the front end and back end of cylinder sleeve, make and to utilize the direction of high-voltage oil liquid conversion oil-feed and be the flexible effect that extruding causes piston rod, the oil pressure pressure of this type of metal extrusion press is essential to be set greatly, most metal can extruding in bulk could be combined into closely knit piece ingot shape volume, also very big because of the oil pressure pressure poundage that uses, therefore the spare part of piston often is the element that weares and teares easily, in case causing damage, must keep in repair in piston ring, whole piston ring conventional construction is the structure of single integral body, so it is higher to change the required expense cost of new parts.And the rubber ring on the piston is to be linked in the chase of piston only, rubber ring desires to be inserted in the work in combination that chase is a difficulty, because of the circle of rubber ring footpath bigger, ring wall is also very thick, the hardness of rubber ring is also higher, then need effort in the extreme so rubber ring will be inserted in chase, so, then can have high combination and disassemble convenience if piston ring can be made knockdownly.

Summary of the invention

Main purpose of the present utility model is to provide a kind of piston structure of metal extrusion press oil hydraulic cylinder to improve, and has to reach the easy effect of maintain and replace to often bearing easy rubber ring and the piston ring that damages of high-voltage oil liquid.

Secondary objective of the present utility model is to provide a kind of piston structure of metal extrusion press oil hydraulic cylinder to improve, and can allow piston ring become multiple combined-type, as the opinion with maintenance cost, can reach the principle that maintenance cost is more saved.

For reaching above-mentioned purpose, the piston structure of the utility model oil hydraulic cylinder improves, and is provided with a cylinder sleeve, a compound piston ring, two-piston bar, two oil seal rings, the common formation of a loam cake and axle sleeve group institute.It is characterized in that: be filled into piston ring, piston rod, oil seal ring, loam cake and axle sleeve group in the inside groove of cylinder sleeve respectively, wherein piston ring is the combined type structure and includes first ring plate, two rubber rings, second ring plate and the 3rd ring plate.First ring plate and the 3rd ring plate one ora terminalis are provided with less external diameter, and second ring plate is connected between first and third ring plate, make two rubber rings by clamping in less external diameter, each ring plate is provided with perforation, makes piston rod pass after the perforation on each ring plate with spiral shell spare locking combination.

Other characteristics of the present utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..
