Background technology
At present, in the strip-mill strip industry, traditional reel breathing cylinder apparatus version can clearly reflect in figure one.Being connected by piston rod (1.2), core bar (1.4) internal and external threads between reel and the breathing oil cylinder connects, adapter sleeve (1.3) and hollow main shaft (1.1) close by the bolt handle, adapter sleeve (1.3) is connected with bolt with cylinder body (1.5) simultaneously, and end cap (1.6) and swivel coupling (1.7) also pass through bolts assemblies with cylinder body (1.5).When the in-oil cylinder sealing ring of breathing need be changed, we need fix cylinder body (1.5) earlier end cap (1.6), swivel coupling (1.7) are laid down earlier, unclamping handle between adapter sleeve (1.3) and cylinder body (1.5) closes bolt (1.11) and draws back between the two distance, take off trip bolt (1.10), the dish movable reel, piston rod (1.2) and core bar (1.4) are thrown off, dismantle again nut (1.8), baffle plate (1.9), cylinder body (1.5) is unloaded, the sealing ring that could more renew this moment, as shown in Figure 1.Traditional reel breathing cylinder apparatus shortcoming shows: from whole unloading process, when the in-oil cylinder sealing ring of breathing need be changed, the independent dismounting of breathing oil cylinder is not got off, and each part of breathing oil cylinder all needs to pull down, this has not only strengthened labor strength, and increased maintenance time, thereby reduced the efficient of factory.
Summary of the invention
For overcoming the problem that above-mentioned conventional apparatus exists, the invention provides a kind of method and device of fast quick-detach reel breathing oil cylinder ,Can effectively reduce labor strength, save maintenance time, increase work efficiency.
For achieving the above object, the present invention takes following technical scheme:
A kind of device of fast quick-detach reel breathing oil cylinder, comprise: readily removable coupling head, readily removable separation sleeve, the two ends of described readily removable coupling head are stuck on piston rod and the core bar, the described pad that the end is provided with adjustment that is connected that is stuck in interior piston rod of readily removable coupling head and core bar; The two ends of described readily removable separation sleeve are fixed together by bolt and flange, cylinder head respectively.
The device of described a kind of fast quick-detach reel breathing oil cylinder, readily removable separation sleeve is made up of half separation sleeve a, half separation sleeve b, described half separation sleeve a and half separation sleeve b constitute separation sleeve by bolted, and the two ends of separation sleeve are fixed together by bolt and flange, cylinder head respectively.
The device of described a kind of fast quick-detach reel breathing oil cylinder, readily removable coupling head is made up of half coupling head a, half coupling head b, and described half coupling head a, half coupling head b constitute the coupling head of piston rod and core bar by bolted.
A kind of method of fast quick-detach reel breathing oil cylinder, the half separation sleeve a that at first dismantles, half separation sleeve b, the half coupling head a that dismantles again, half coupling head b just can throw off breathing oil cylinder and hollow main shaft, core bar fully, then the breathing oil cylinder are keeped in repair.
Owing to take aforesaid technical scheme, the present invention produces following superiority:
The present invention dismantles breathing oil cylinder only need dismantle half separation sleeve a, half separation sleeve b and half coupling head a, half coupling head b, breathing oil cylinder and hollow main shaft, core bar are thrown off fully, it is fast and convenient that the present invention dismantles the breathing oil cylinder, and keep in repair very convenient, the present invention can effectively reduce labor strength, save maintenance time, increases work efficiency.
