Abstract
The utility model relates to a copper bush lubricating structure for a presser balance cylinder, which is a special component of a slider of a balance presser, and pertains to the presser technological field. The copper bush lubricating structure comprises a balance cylinder body, a piston inside the balance cylinder body and a piston rod one end of which connects with the piston, the other end of the piston rod passes through a bottom cover and a sealing ring arranged in the bottom cover; a bearing block provided with a copper bush in the inner cavity is sleeved with a piston rod part under the bottom cover, and an oil supply hole and an oil return hole are arranged on the bearing block and the copper bush. The copper bush lubricating structure can connect with a lubricating system of machine tools, thus cycle lubrication is formed, thereby greatly improving the lubrication sufficiency of the copper bush, and improving the lubrication situation of the copper bush; the utility model is simple and reasonable and is helpful for processing, assembly, and maintenance; the utility model is beneficial to improve the service life of spindle sleeves, thereby enhancing the overall performance of the presser, having strong practicability and obvious economic benefits.
Description
Technical field
The utility model relates to a kind of copper bush of press balance cylinder lubricating structure, and the compensating cylinder piston rod pumps in its copper sheathing, is the special-purpose member of balance pressure machine slide block, belongs to the press technologies field.
Background technique
Slide block in the press machine pumping from the upper dead center to the lower dead centre except that the guide rail of need control circuit, power and setting, also needs the compensating cylinder in the slide block to come balance slide block and patrix weight, avoids the additional impact in the working procedure.Copper sheathing in the existing compensating cylinder is arranged in the lower cover of compensating cylinder, piston rod passes the copper sheathing in lower cover and the lower cover, seal ring also is set in the lower cover above copper sheathing, former design is to allow lubricant oil be penetrated in the copper sheathing along the piston rod outer wall copper sheathing is lubricated, but owing to there is seal ring to seal gas above the copper sheathing, in piston rod movement process repeatedly up and down, in fact lubricant oil be difficult to enter in the copper sheathing.Brought and in movement process, sent abnormal sound easily, killed, situation such as copper sheathing wearing and tearing too early, shortcoming such as cause that compensating cylinder is lacked working life, and influenced the overall performance of press machine.
Summary of the invention
The purpose of this utility model is to kill, send when moving situation such as abnormal sound, cause deficiencies such as compensating cylinder working life is short at what the insufficient lubrication that existing balance cylinder copper bush exists because of structural factor brought, provide not only to help processing, but also help improving lubrication state, thereby help improving a kind of copper bush of press balance cylinder lubricating structure of compensating cylinder working life and press machine overall performance.
The purpose of this utility model is achieved through the following technical solutions, a kind of copper bush of press balance cylinder lubricating structure, comprise balance cylinder block, piston in the balance cylinder block and an end connect the piston rod of piston, the other end of piston rod passes lower cover and is arranged on seal ring in the lower cover, the piston rod portion under the lower cover that it is characterized in that is nested with the bearing support that inner chamber has copper sheathing, and bearing support is connected through fastening piece with lower cover, and oil inlet hole and spill port are set on bearing support and the copper sheathing.
The connecting part of bearing support and lower cover is provided with corresponding ladder.
In the bearing support under the copper sheathing ring groove is set, inserts oil sealing in the ring groove.
Some roads axial oil groove is set on the copper sheathing endoporus.
The utility model is the improvement to existing copper bush of press balance cylinder lubricating structure, with the bearing support combination of original copper sheathing and setting; And oil inlet hole and spill port be set on bearing support and copper sheathing; Can link to each other with the lubrication system of lathe, form circulating lubrication.Improved the adequacy of copper bush lubrication greatly, improved the lubrication state of copper sheathing, the utility model is simple and reasonable, helps processing, assembling, maintenance; Help improving the working life of axle sleeve, thereby improved the overall performance of press machine, have very strong practicability and tangible economic benefit.
Description of drawings
Fig. 1 is the utility model partial structurtes schematic representation:
Among the figure, 1 oil sealing, 2 bearing supports, 3 copper sheathings, 4 oil grooves, 5 piston rods, 6 lower covers, 7 balance cylinder blocks, 8 oil inlet holes, 9 spill ports.
Embodiment
Further specify the utility model with example in conjunction with the accompanying drawings, the utility model is by balance cylinder block 7, piston, bearing support 2, copper sheathing 3 and piston rod 5 constitute, bearing support 2 is fixed on the lower cover 6 of balance cylinder block 7, bearing support 2 is provided with corresponding ladder with the connecting part of lower cover 6, bearing support 2 is fastened on the compensating cylinder lower cover 6 by screw, copper sheathing 3 is fixed in the endoporus of bearing support 2 by Cock screw, the below, inside of copper sheathing 3 lower shaft bearings 2 is provided with seal groove, seal groove is built-in with oil sealing 1, and bearing support 2 is provided with oil inlet hole 8 with copper sheathing 3, spill port 9, lubricant oil enters copper sheathing 3 from the oil inlet hole 8 of bearing support 2 and is stored in the oil groove 4, flow out from the spill port 9 of copper sheathing 3 again after having expired, form circulating lubrication through bearing support 2.
