Description
Technical field
The present invention relates to a kind of balance cylinder copper bush lubrication sealing device, particularly a kind of novel balance cylinder copper bush lubrication sealing device.Belong to the press technologies field.
Background technique
Compensating cylinder in the press machine is to be used for balance slide block and patrix weight, avoids the additional impact in the working procedure.Copper sheathing in existing compensating cylinder is arranged in the compensating cylinder loam cake, piston rod passes the copper sheathing in loam cake and the loam cake, seal ring also is set in the loam cake 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, copper sheathing grinds situations such as an ancient egg-shaped, holed wind instrument too early, causes shortcomings such as compensating cylinder working life is short, and influenced the overall performance of press machine.In addition, the seal ring that is used for sealing between piston rod and the loam cake is arranged in the middle of the loam cake, must remove loam cake fully in case an ancient egg-shaped, holed wind instrument is bad, so the installation replacing is also cumbersome.
Summary of the invention
The objective of the invention is to kill, send when moving situation such as abnormal sound because of what the insufficient lubrication that exists brought at existing balance cylinder copper bush, cause deficiencies such as compensating cylinder weak point in working life, provide and not only help processing, but also help improving lubrication state, and change seal ring easily, thereby help improving a kind of novel balance cylinder copper bush lubrication sealing device of compensating cylinder working life and press machine overall performance.
The objective of the invention is to be achieved through the following technical solutions, a kind of novel balance cylinder copper bush seal arrangement, comprise the piston rod that a piston in the balance cylinder block, balance cylinder block and an end connect piston, the other end of piston rod passes loam cake and is arranged on seal ring in the loam cake, it is characterized in that the piston rod portion that covers is nested with the bearing support that inner chamber has copper sheathing, bearing support is connected through fastening piece with loam cake, oil inlet hole and spill port are set on bearing support and the copper sheathing, the seal ring of packed-piston bar and loam cake effect has been installed between bearing support and loam cake.The connecting part of bearing support and loam cake is provided with corresponding ladder, and wherein the seal ring of packed-piston bar and loam cake just is arranged in the 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.
Beneficial effect: the present invention 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 present invention is simple and reasonable, is used in processing, assembling, maintenance; Help improving the physical life of axle sleeve, thereby improved the overall performance of press machine, have very strong practicability and tangible economic benefit.The seal ring of packed-piston bar and loam cake is arranged in the shoulder hole, so the bearing support of only need dismantling is with regard to replaceable maintenance, so installation and maintenance are convenient.
