Description
Technical field
The utility model relates to a kind of cutting machine device, especially relates to a kind of to producing the isostructural improvement of cutting machine gas expansion shaft device of aluminium foil.
Background technology
Generally in the manufacture of metallic materials such as known production aluminium foil, often need use gas expansion shaft again in the cutting machine and do the volume of metal coiled strip material such as aluminium foil and send operation.Chinese patent discloses a kind of gas expansion shaft, and (Granted publication number: CN 2928801Y), it comprises an axostylus axostyle, is hollow form; One charging portion is located in this axostylus axostyle; A most linkage part are located at the position that this charging portion is close to this axostylus axostyle, and an end of this linkage part is to protrude outside this axostylus axostyle; A most curved tabs, be located between these two ends, axostylus axostyle surface, and this curved tabs is that an end that protrudes this axostylus axostyle with this linkage part respectively joins along the axial middle position of this axostylus axostyle, one side of the axially parallel of this curved tabs and this axostylus axostyle is convexly equipped with a salient, be respectively equipped with a notch part between the adjacent salient of this curved tabs in office two, and this curved tabs then is respectively equipped with another notch part with the side in addition of the axially parallel of this axostylus axostyle in the position of relative this salient, this curved tabs then is respectively equipped with another salient with the side in addition of the axially parallel of this axostylus axostyle in the position of relative this notch part, this salient inserts respectively in this another notch part, and this notch part is pegged graft for this another salient respectively, this curved tabs is before the unaerated still of this charging portion, the top of this salient and another salient lays respectively at the bottom near this notch part and another notch part, and after this charging portion inflation, this linkage part promotes this curved tabs respectively, makes the top of this salient and another salient lay respectively at the position near the top of this notch part and another notch part; This linkage part comprises: guide card in most, be located between these charging portion two ends in relative this curved tabs central position of its surface periphery, should in guide card before this charging portion unaerated be and this interior spindle wall spacing of being separated by, and guide card is after the inflation of this charging portion in this, and guide card is to move to position near this interior spindle wall to this interior spindle wall in this; Most catch bars are formed, and an end of this catch bar is provided in a side of the one side of this inner guide plate in the face of this axostylus axostyle, and this catch bar in addition end be to protrude respectively outside this axostylus axostyle, and be connected together mutually with a relative curved tabs respectively.But the structure of this gas expansion shaft is comparatively complicated, manufacturing cost is higher, and other present gas expansion shaft is because when inflation harmomegathus, can cause serious off-centre between gas expansion shaft and the sleeve pipe, maximum can reach 1.6mm, and therefore can cause also can be seriously eccentric when cutting the aluminium foil product, cause tension fluctuation very big, the aluminium foil band is neglected pine and is neglected tightly, and gas expansion shaft is beated very big, causes problems such as serious, the frequent broken belt of product staggered floor, gas expansion shaft distortion, bearing life shortening.
The utility model content
The utility model technical issues that need to address provide a kind of cutting machine gas expansion shaft device, it mainly is that to solve the structure of existing in prior technology gas expansion shaft comparatively complicated, manufacturing cost is higher, and other present gas expansion shaft is because when inflation harmomegathus, can cause between gas expansion shaft and the sleeve pipe serious eccentric, therefore can cause also can be seriously eccentric when cutting the aluminium foil product, cause tension fluctuation very big, the aluminium foil band is neglected pine and is neglected tight, gas expansion shaft is beated very big, causes the technical matters of serious, the frequent broken belt of product staggered floor, gas expansion shaft distortion, bearing life shortening etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
Cutting machine gas expansion shaft device of the present utility model, comprise gas expansion shaft, the gas expansion shaft two ends are provided with joint, gas expansion shaft is socketed with sleeve pipe outward, it is characterized in that having some elongated slots on the described gas expansion shaft, be embedded with the harmomegathus key in the elongated slot, gas expansion shaft inside is provided with the air bag that connects the harmomegathus key, leave the gap between sleeve pipe and the gas expansion shaft, total gap L is 0.55～0.65mm.Sleeve pipe can be aluminum casing, gas expansion shaft is when inflation dress harmomegathus, it can produce off-centre, be contacting with sleeve pipe more at least of gas expansion shaft, maximum clearance between gas expansion shaft and the sleeve pipe can be 0.55～0.65mm, and the best can be 0.6mm, can reduce the offset of gas expansion shaft like this, can improve the speed of cutting, improve the output and the quality of product.After being full of gas in the air bag, the harmomegathus key that can promote to be embedded in the elongated slot moves up and down, thereby plays the effect of harmomegathus.The shape of harmomegathus key and the shape of elongated slot are complementary.
As preferably, the external diameter of described gas expansion shaft is 75.55～75.65mm.Because general sleeve pipe is outsourcing, its internal diameter is constant, therefore the external diameter of former gas expansion shaft is brought up to 75.55～75.65mm from 74.6mm, can effectively reduce
As preferably, the described harmomegathus key that is positioned at the gas expansion shaft two ends respectively is 2; The harmomegathus key that is positioned at the gas expansion shaft middle part is the multi-turn setting, and every circle harmomegathus key is 4.
Therefore, the utlity model has the external diameter that has increased gas expansion shaft, thereby dwindled the offset after the sleeve pipe harmomegathus, reduced the probability of cutting staggered floor and broken belt, prevent the gas expansion shaft distortion, increased the life-span of bearing, improve the speed of cutting, characteristics such as output that product is cut and quality are all higher, and be simple and reasonable for structure.
