Abstract
The utility model relates to a taper cutting device of a wind-driven tower sector steel cylinder, which is also applied to the cutting of other sector plate tapers. The taper cutting device is composed of a cutting machine and a floor gauge bar, and is characterized in that the floor gauge bar is provided with guide wheels for the travel of the cutting machine. Compared with the prior art, the utility model has the advantages that the taper cutting device is simple and easy to realize, the taper cutting is precise, the precision is high, and the effect is good; the taper quality fully accords with the standard precision technology requirement, and the work efficiency is greatly enhanced.
Description
Technical field
The utility model relates to a kind of wind power generation stepped fan-shaped steel plate tube groove cut-off apparatus, also is applicable to other fanning strip groove cutting.
Background technology
When making wind power tower drum, the tens of rice of tower tube height overall, by being formed by connecting by the high-strength bolt flange between the multistage tower tube, each section tower tube is made up of the truncated cone-shaped shell ring of different-thickness, as shown in Figure 1.The tower barrel structure belongs to an end to be fixed, and an end is mast structure freely, requires opposing moment of flexure ability strong.The perpendicularity of each section shell ring, flatness precision, weldquality class requirement height.
The tower tube resolves into each section truncated cone-shaped shell ring as shown in Figure 2, is sector structure by middle footpath unfolding and cutting, and as shown in Figure 3, A, B, C, D face list shovel 30 ° of grooves around requiring.
Shell ring gas cutting technical parameter: (1) flatness 1mm; (2) vertical height 1mm; (3) machined surface perpendicularity＜0.5mm; (4) machined surface surface roughness ▽ 12.5.
Conventional cutting method is: a kind of is large-scale multi-axis numerical control cutting equipment, though efficient and precision are good, it costs an arm and a leg, and popularization and application is relatively poor.Another kind method is to lay radius to launch the identical arc track of radius with steel plate, cuts with semi auto cutting machine.The shortcoming that this kind method exists is:
(1) arc radius of track is difficult to satisfy the needs of cutting radius.
(2) the cutting track extends repeatedly, does not guarantee the continuity of cutting.
(3) inefficiency does not satisfy the requirement of cutting accuracy.
Summary of the invention
The wind power tower drum fan-shaped steel plate groove cut-off apparatus that the purpose of this utility model provides a kind of cutting accuracy height, cutting machine is not wandered off.
For achieving the above object, the utility model is by the following technical solutions:
Wind power tower drum fan-shaped steel plate groove cut-off apparatus, comprise cutting machine, gauge bar, on the ground gauge bar, be provided with the directive wheel of cutting machine walking.
Compared with prior art, the utility model has the advantages that: simple, cost is low, and the groove cutting is accurate, and the precision height is effective.
Description of drawings
Fig. 1 is the structural representation of wind power tower drum.
Fig. 2 is the structural representation of truncated cone-shaped shell ring.
Fig. 3 is fan-shaped baiting structure figure.
Fig. 4 is the structure chart of wind power tower drum groove cut-off apparatus.
The specific embodiment
See Fig. 4, wind power tower drum fan-shaped steel plate groove cut-off apparatus, this device is that existing cutting machine running part is reequiped, make it to produce in the process of walking side force, and be equipped with guider, make it stable operation on segmental arc, its structure connects ground gauge bar 2 by semi auto cutting machine 1 and forms, for guaranteeing cutting accuracy and cutting effect, one 6302 bearing is installed, on the ground of semi auto cutting machine 1 gauge bar 2 as the directive wheel 3 of cutting machine walking.Directive wheel 3 drives semi auto cutting machine and carries out the groove cutting along the arc incision face walking of sector structure steel plate 4.The cutting effect of groove is very good, and the groove quality meets the precision techniques requirement of standard fully, has improved operating efficiency greatly.
Claims (1)
1, wind power tower drum fan-shaped steel plate groove cut-off apparatus, comprise cutting machine, gauge bar, it is characterized in that, on the ground gauge bar, be provided with the directive wheel of cutting machine walking.
