Abstract
The utility model relates to a high-frequency straight welded pipe production line which has the technical characteristics that the production line is composed of an uncoiler, a leveler, a steel plate shearer, a butt welding machine, a spiral loop machine, an FFX forming unit, a high-frequency welding machine, a flaw detector, a heat treatment device, a sizing mill, a length-fixing cutting device, a pipe-end flat head chamfering machine and a hydrostatic testing machine which are sequentially connected with one another by a transmission device. In the high-frequency straight welded pipe production line, the design is reasonable, the online flaw detector and the intermediate-frequency induction heat treatment device are additionally arranged, a welded pipe after being welded at high-frequency is detected on line so as to screen qualified products for the next procedure, and heat treatment is carried out on the welded pipe through the intermediate-frequency induction heat treatment device, therefore, the quality of the product is ensured, the controlling function on the product quality is realized, the finished product ratio is improved, and the high-frequency straight welded pipe production line can be widely applied to the field of the high-frequency straight welded pipe.
Description
Technical field
The utility model belongs to the ERW field, especially a kind of high-frequency straight welded pipe production line.
Background technology
ERW is the strip steel band of certain specification to be rolled into the pipe shape and with the vertical masonry joint steel pipe that is welded through the high-frequency welding unit.Because ERW has characteristics such as hardness height, smooth surface; Therefore obtained using widely; The industrial field that before some, belongs to seamless steel pipe like vehicle transmission pipe, boiler pressure pipe, petroleum casing pipe, oily vapour carrier pipe etc., is replaced by ERW gradually.Problems such as existing ERW exists difficult quality to control in process of production, yield rate is low.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of and can guarantee product quality and the high high-frequency straight welded pipe production line of yield rate.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of high-frequency straight welded pipe production line is connected and composed through transmitting device by uncoiler, level(l)ing machine, plate shearing machine, butt welding machine, spiral loop machine, FFX shaping machine set, high-frequency welder, defectoscope, annealing device, sizing mill, scale cutter sweep, pipe end plain-end chamfering machine and hydrostatic testing machine successively.
And described defectoscope is a supersonic detector.
And described annealing device is the Medium frequency induction annealing device.
The advantage and the good effect of the utility model are:
The utility model is reasonable in design; Through increasing online carrying out flaw detection appearance and Medium frequency induction annealing device, the welded tube of high-frequency welding is carried out online detection get into next process, and welded tube is heat-treated through the Medium frequency induction annealing device to filter out qualified product; Guaranteed the quality of product; Thereby realized the controllable quality function has been improved yield rate, can be widely used in the high-frequency straight seam welded pipe field.
Description of drawings
Fig. 1 is the connection sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of high-frequency straight welded pipe production line; As shown in Figure 1; Connect and compose successively by uncoiler, level(l)ing machine, plate shearing machine, butt welding machine, spiral loop machine, FFX shaping machine set, high-frequency welder, supersonic detector, Medium frequency induction annealing device, sizing mill, scale cutter sweep, pipe end plain-end chamfering machine and hydrostatic testing machine, be connected through transmitting device between each equipment.The innovation part of this patent is behind high-frequency welder, to add a supersonic detector and Medium frequency induction annealing device; Can detect the welding tube quality after high-frequency welder welds automatically through supersonic detector; Screen for defective welded tube, guaranteed the quality of product, welded tube is carried out the heat treatment of online weld seam through the Medium frequency induction annealing device; With the mechanical performance of improving welded tube and eliminate residual stress, thereby strengthen the rigidity of ERW.
The course of work of the utility model is: the steel band of rolling is smoothed processing by level(l)ing machine after the uncoiler uncoiling; Plate shearing machine trims processing; Butt welding machine will carry out butt welding to be handled; The spiral loop machine carries out spiral loop to be handled; The FFX shaping machine set is carried out the bend pipe moulding to steel band; High-frequency welder welds the steel band interface; The supersonic detector butt welded seam carries out carrying out flaw detection; The Medium frequency induction annealing device is heat-treated welded tube; Sizing mill carries out the sizing screens; The scale cut goes out to meet the ERW of size; The ERW two ends of pipe end plain-end chamfering machine after to cutting are led rib and hydrostatic testing machine and ERW is carried out water pressure test detection are obtained final high-frequency straight seam welded pipe.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the specific embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
