Abstract
The invention relates to an auxiliary device for molding a large-diameter and thin-walled cylinder, wherein an arc-shaped bracket is fixed with a bottom plate by an inclined strut, and a roller wheel which protrudes outside the inner arc surface of the arc-shaped bracket is fixed on the inner arc surface of the arc-shaped bracket. The auxiliary device is simple in structure; the problems that a roll-out end sinks and is not a round due to poor rigidity when the large-diameter and thin-walled cylinder is molded can be solved, so that the molding of the large-diameter and thin-walled cylinder is time-saving, labor-saving and safer.
Description
Technical field
The invention belongs to plate forming servicing unit, particularly a kind of forming auxiliary device of large diameter thin wall cylindrical shell.
Background technology
In recent years, along with the adjustment of China's energy resource structure, natural gas becomes one of China's main energy sources gradually, along with " enforcement of the engineering such as West-east Gas, " extra large gas logs in ", " Russia's gas south is sent "; energy proportion shared by natural gas is by increasing; the use of natural gas is very universal, along with the expansion gradually of natural gas user amount, will increase as the natural gas storing supplemented of gas ductwork conveying, the demand of transporting equipment thereupon.LNG is cheap relative to CNG vehicle transportation cost, and bicycle freight volume is large, becomes the main flow of highway transportation, and for realizing maximum filling weight, turns to design concept with large volume, light weight.But after lightweight, due to the thin poor rigidity of the large wall of diameter, just improve manufacture difficulty, on condition that an external force is not applied, the rigidity by self when cylindrical shell is shaping is difficult to into garden, assists, there is security risk by people.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the body formed servicing unit of a kind of large-diameter thin-wall cylinder, its structure is simple, efficiently solve large-diameter thin-wall cylinder body formed time because poor rigidity rolls out, end sinks, the problem of not Cheng Yuan, make the shaping of large diameter thin wall cylindrical shell, save time, laborsaving, economize people, safer.
The present invention solves the technical scheme that its technical problem takes: arc-shaped bracket is fixed by diagonal brace and base plate, the intrados of arc-shaped bracket is fixed with the roller protruding arc-shaped bracket intrados.
The present invention is not only easy for installation, flexible operation, steadily, long service life, safe and reliable, stressed good, not fragile face peripherally again, little at this auxiliary lower body formed resistance of large-diameter thin-wall cylinder, laborsaving, people from province, meet the body formed requirement of large-diameter thin-wall cylinder, decrease the auxiliary of manpower, reduce cost, avoid security risk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is the A place enlarged drawing in Fig. 2 of the present invention;
Fig. 4 is using state schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, arc-shaped bracket 1 is fixed by diagonal brace 3 and base plate 5, the intrados of arc-shaped bracket 1 is fixed with the roller 2 protruding arc-shaped bracket 1 intrados.
Described arc-shaped bracket 1 and the structure of diagonal brace 3 are fixed with two covers on base plate 5, and two inner room connectors 12 are reinforced.
Described roller 2 is fixed on axle 7 by deep groove ball bearing 8, shaft end ring 9, and axle 7 two ends are processed into arc, are fixed on arc-shaped bracket 1 by pressing plate 10.Prevent axle 7 from rotating, roller 2 axial float, guarantees even running.As shown in Figure 3.
Described arc-shaped bracket 1 there is gap, fixed axis 7 on gap.Easy installation and removal.
The two ends of described base plate 5 curve left and right alice 6,4 upwards.Not fragile ground.
Described arc-shaped bracket 1 inside radius 15-30mm larger than cylindrical shell outer radius.
During use, the present invention is placed in plate roller 11 other.As shown in Figure 4.
