The thick-wall titanium welded pipe forming machine comprises a primary forming section (4), a fine forming section (5) and a setting section (6). The thick-wall titanium welded pipe forming machine is characterized in that the primary forming section (4) is formed by four forming plain-barrelled roll racks (1) and three guiding vertical roll racks (2) which are alternately arranged; the fine forming section (5) is formed by at least three forming plain-barrelled roll racks (1) and at least three guiding vertical roll racks (2) which are alternately arranged; the setting section (6) is formed by arranging at least two guiding plain-barrelled roll racks (3). The thick-wall titanium welded pipe forming machine is simple in structure; through trial production, a cold-rolled titanium strip coil is directly made into a thick-wall titanium welded pipe with the outer diameter of 15-20mm, the wall thickness of 1.5-2.0mm and the wall thickness-to-outer diameter ratio more than or equal to 10%; the titanium welded pipe is uniform in the wall thickness and outer diameter, dimensional accuracy is higher than that of a seamless pipe, mechanical properties of the titanium welded pipe can be at the level of a seamless titanium pipe in the same specification, and technical requirements of the titanium welded pipe are met.
Description
Technical field
The utility model relates to a kind of titanium welding pipe forming machine, and a kind of thick-walled titanium welded tube forming machine specifically particularly relates to the thick-walled titanium welded tube forming machine of a kind of wall footpath ratio >=10 ﹪.
Background technology
The titanium pipe has the special performances such as specific strength is high, corrosion resistance is strong, long service life, and security of operation is stable.Due to titanium in wet chlorine medium and seawater, there is extremely excellent corrosion resistance, even also maintain good corrosion resistance in the seawater polluted, therefore, the titanium pipe is widely used in the equipment such as heat exchanger that the industries such as electric power, chemical industry, seawater utilization and ocean engineering, Aero-Space are relevant, condenser, evaporimeter.
Titanium Guan Yinqi manufacture craft and pipe shape difference used are divided into welding titanium pipe and the large class of seamless titanium tube two.The seamless pipe production technology is: the operation such as circular pipe blank heats, bores a hole, takes the lead, annealing, pickling, oiling, multi-pass cold-drawn (cold rolling), heat treatment, aligning, scale, flaw detection, water pressure test.And process for producing welded pipe is: operations such as uncoiling, shearing end weldering, storing, cleaning, moulding, welding, pre-sizing, online annealing, smart sizing, eddy current inspection, laser diameter measurement, cutting, ultrasonic examination, air seal tests.
For the titanium pipe of wall footpath ratio≤8 ﹪, due to moulding and the welding than being easier to, generally adopt process for producing welded pipe.And, to the titanium pipe of wall footpath ratio >=10 ﹪, because the titanium mechanical property is special, particularly yield tensile ratio is high, in forming process resilience large, forming machine comprises that shaped flat roller frame, guiding standing roller frame, arranging of guide flat roller frame form material impact to it.Each frame spacing is long, and resilience is abundant, and plastic deformation is insufficient, and cause apparatus for production line huge, extend long; Each frame spacing is too short, though can suppress largely its bounce-back, operating space is little, and the roll change difficulty strengthens.So, adopt at present the seamless pipe production technology.But, there are pickling, degreasing process in the seamless pipe production technology, not environmental protection of production process, and wall thickness deviation is large, concentricity is poor, and Product Precision is difficult to control.
Summary of the invention
The purpose of this utility model is to provide a kind of thick-walled titanium welded tube forming machine of processing wall footpath ratio >=10 ﹪.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of thick-walled titanium welded tube forming machine, it comprises pre-profiling section, precisive shaped section, typing section, and described pre-profiling section is alternately arranged and formed by 4 shaped flat roller frames and 3 guiding standing roller frames; Described precisive shaped section is alternately arranged and is formed by least 3 shaped flat roller frames and at least 3 guiding standing roller frames; Described typing section is arranged and is formed by least 2 guide flat roller frames.
For avoiding the scuffing of roll wear and titanium tube-surface, the shaped flat roller frame in the utility model precisive shaped section and the top roll of guide flat roller frame are the combination roller of copper alloy and steel alloy.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, through trial production, directly making external diameter by the cold rolled titanium roll coil of strip is that 15 ㎜～20 ㎜, wall thickness are 1.5 ㎜～2.0 ㎜, and the thick-walled titanium welded tube of wall footpath ratio >=10 ﹪, its wall thickness of titanium welding pipe, external diameter are even, dimensional accuracy is better than seamless pipe, and its mechanical property can reach same specification seamless titanium tube level, and meets the specification requirement of ASTM B338 and GB/T 3625 standard titanium welding pipes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of thick-walled titanium welded tube forming machine, it comprises pre-profiling section 4, precisive shaped section 5, typing section 6, described pre-profiling section 4 is alternately arranged and is formed by 4 shaped flat roller frames 1 and 3 guiding standing roller frames 2; Described precisive shaped section 5 is alternately arranged and is formed by least 3 shaped flat roller frames 1 and at least 3 guiding standing roller frames 2; Described typing section 6 is arranged and is formed by least 2 guide flat roller frames 3.
For avoiding the scuffing of roll wear and titanium tube-surface, the shaped flat roller frame 1 in the utility model precisive shaped section 5 and the top roll of guide flat roller frame 3 are the combination roller of copper alloy and steel alloy.
During the utility model application, at first adopt the both arms uncoiler, the titanium band of rolling is evenly launched, clean.The titanium band is processed through the forming machine roll bending formation, moulding adopts W recurvation bending molding process again, i.e. titanium belt edge part forward bending, and the mid portion back-flexing, obtain the nearly circular pipe blank that band edge fits tightly.W recurvation bending molding process has increased the crooked arc length in marginal portion, makes edge deformation abundant, and pipe difference in height in forming process is less, and the relative extension in edge is greatly reduced, and difference has been dwindled in the bulge of having avoided the edge longitudinal elongation to cause simultaneously.The present embodiment adopts 1,6 guiding standing roller frames 2 of 7 shaped flat roller frames and 4 guide flat roller frames 3, front 4 shaped flat roller frames 1 and 3 guiding standing roller frames 2 are alternately arranged and are formed pre-profiling section 4, the the 5th to the 7th shaped flat roller frame 1 and 3 guiding standing roller frames 2 are alternately arranged and are formed 5,4 guide flat roller frames of precisive shaped section, 3 composition typing sections 6.Adopt plasma weldering and the combination of argon tungsten-arc welding rush-harvesting and rush-planting during welding, plasma gun is front, and tungsten argon arc welding gun is rear.Finally by pre-sizing, online annealing, smart sizing, detection, packing.
It is that 15 ㎜～20 ㎜, wall thickness are 1.5 ㎜～2.0 ㎜ that the utility model can directly be made external diameter by the cold rolled titanium roll coil of strip, and the thick-walled titanium welded tube of wall footpath ratio >=10 ﹪, its wall thickness of titanium welding pipe, external diameter are even, dimensional accuracy is better than seamless pipe, its mechanical property can reach same specification seamless titanium tube level, and meets the specification requirement of ASTM B338 and GB/T 3625 standard titanium welding pipes.
