Abstract
The invention discloses a novel balance cylinder circulating lubrication system of a pressing machine. An air source is communicated with an air reservoir through a stop valve; two air channel pipelines are connected to the inside of the air reservoir, and one of the air channel pipelines is a trunk path which is connected with an atomized lubricator first after being guided out from the air reservoir; an air path is divided into two paths after coming out of the atomized lubricator, and one path leads to other pneumatic components of the pressing machine, while the other path is connected with a one-way valve; the mounting direction of the one-way valve satisfies that a back pressure relation can be formed between the one-way valve and balance cylinders; the pipeline coming out of the one-way valve is divided into three branches which are communicated with two balance cylinders respectively, while another balance cylinder is connected with a control one-way valve; the mounting direction of the control one-way valve satisfies that a back pressure relation can be formed between the control one-way valve and the balance cylinders connected with the control one-way valve; and a control pipeline of the control one-way valve is communicated with air inlets and air outlets of two balance cylinders. After the control one-way valve is connected with the two balance cylinders, the other end of the control one-way valve is connected with the air reservoir through a corresponding pipeline.
Description
Technical field
The present invention relates to a kind of balance cylinder circulating lubrication system of pressing machine, particularly a kind of novel balance cylinder circulating lubrication system of pressing machine.Belong to the press technical field.
Background technology
Compensating cylinder is the critical function parts in the forcing press, the effect that it played mainly contains two aspects: it plays the effect to the moving component buffering on the one hand, avoid interconnecting between the moving component owing to there is the gap, impact at the volley, and because noise that this impact brought, to the damage of moving component.On the other hand, it plays safety effect, it can misfunctioning of brake, control system take place unusual in, hinder slide block and quicken to glide, and because the security incident that this unusual downslide brought.Because the important function that in forcing press work, played of compensating cylinder, so, in, the high speed equal pressure machine large-scale, accurate, compensating cylinder is installed generally at some.Structurally, compensating cylinder is equivalent to a single-acting cylinder, is equivalent to gas spring on operation principle, at work, all the time feed the compressed air of fixation pressure in the pressure chamber of cylinder, the piston rod of cylinder is fixedlyed connected with slide block, and piston synchronously moves with slide block.
In the real work of forcing press, the phenomenon that compensating cylinder usually leaks gas, thereby its function is seriously influenced, analyze the main cause discovery that balance is leaked gas easily, compensating cylinder except frequent motion cause ring wear between cylinder body and the piston cause the former of gas leakage thereby, the structural defective of the air-channel system of compensating cylinder, and because the insufficient lubrication that brings of this defective also is to cause ring wear between cylinder body and the piston to cause the major reason of gas leakage.The defective of this structure is: the compressed air in the feeding compensating cylinder can't be implemented in the whole air-channel system and circulate, so, being installed in the lubricating oil that oil sprayer provided in the air-channel system is difficult in the whole gas circuit and circulates, thereby, also just can not realize effectively lubricating, even can cause the lubricating oil wretched insufficiency of the moving component that has moving component.
Summary of the invention
The objective of the invention is to: a kind of novel balance cylinder circulating lubrication system of pressing machine is provided, this balance cylinder circulating lubrication system of pressing machine, compressed air can form shuttling movement in whole air-channel system, with the lubricating oil that oil sprayer provided in the air-channel system, bring compensating cylinder by the circulation gas circuit, make compensating cylinder realize good lubricating, overcoming compressed air in the existing compensating cylinder can't be implemented in the whole air-channel system and circulate, the lubricating oil that oil sprayer provided in the air-channel system is difficult in the whole gas circuit and circulates, can not realize effectively lubricating, cause the lubricating oil wretched insufficiency of moving component moving component, the compensating cylinder moving component is easy to wearing and tearing, the defective of compensating cylinder cisco unity malfunction.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of novel balance cylinder circulating lubrication system of pressing machine, it is made up of source of the gas, stop valve, gas receiver, oil sprayer, other pneumatic element of forcing press, compensating cylinder, control check valve, check valve.Source of the gas communicates with gas receiver by stop valve, from gas receiver, pick out two gas circuit pipelines, wherein one the tunnel is trunk roads, prime minister and oil sprayer joined after it was drawn from gas receiver, after gas circuit is come out from oil sprayer, be divided into two-way, one the tunnel leads to other pneumatic element of forcing press, other one the tunnel links to each other with check valve, the installation direction of check valve is: can form the back pressure relation between it and the compensating cylinder, tell 3 branch roads from the pipeline that check valve comes out, 3 each branch road communicate with two compensating cylinders respectively, another links to each other with the control check valve, and the installation direction of control check valve is: can form the back pressure relation between the compensating cylinder that it and its link, the control piper of control check valve is connected with the air inlet/outlet of two compensating cylinders.After controlling check valve and two compensating cylinders linking to each other, an other end links to each other with gas receiver by corresponding pipeline.
Its operation principle is: during the work of forcing press pneumatic element, air-flow flows in trunk roads, thereby the oil in the oil sprayer is sent in the trunk roads by certain amount, wherein a part flows to other pneumatic element of forcing press, the check valve of leading up in addition enters cylinder, forcing press is when work, because slide block spurs the compensating cylinder piston rod of cylinder downwards forcibly, so, the pressure of equilibrium,transient cylinder air inlet is a bit larger tham the pressure in the gas receiver, at this moment check valve oppositely ends, and the control check valve since the pressure of control end greater than the pressure in the gas receiver, so control the check valve conducting this moment, form the circulation of air-flow, and when the compensating cylinder piston moves upward, just in time opposite at an instantaneous check valve with the path of control check valve, at this moment, also form of short duration gas circuit circulation, so under these two kinds of situations, lubricating oil also circulates with air-flow.
Beneficial effect: a kind of novel balance cylinder circulating lubrication system of pressing machine, this balance cylinder circulating lubrication system of pressing machine, because compressed air can form shuttling movement in whole air-channel system, can be with the lubricating oil that oil sprayer provided in the air-channel system, bring compensating cylinder by the circulation gas circuit, make compensating cylinder realize good lubricating, overcoming compressed air in the existing compensating cylinder can't be implemented in the whole air-channel system and circulate, the lubricating oil that oil sprayer provided in the air-channel system is difficult in the whole gas circuit and circulates, can realize effectively lubricating, cause the lubricating oil wretched insufficiency of moving component moving component, the compensating cylinder moving component is easy to wearing and tearing, the defective of compensating cylinder cisco unity malfunction.
