Abstract
The utility model relates to a double-end metal helical corrugated tube molding device which comprises two opposite chucks. A relative sliding stroke is arranged between the two chucks. The chucks are driven to rotate trough a rotation driving device. One or more point controlling bosses are arranged on the chucks, and can retract along the axial direction. According to the double-end metal helical corrugated tube molding device, after annealing and other processes are carried out on a tube blank of a turn-knob technique, bent use or a bending test is carried out on a product, and service life is over 5 times longer than that of a product manufactured by a traditional technique. The double-end metal helical corrugated molding device is not constrained by one or more arcing screws, the point controlling bosses can be replaced according to the demand to achieve needed requirements. The double-end metal helical corrugated tube molding device is high in automation degree. A mold can be replaced and adjusted easily. Arching turn-knob technique requirements of different pipe diameters can be achieved.
Description
Technical field
The present invention relates to the metallic spiral corrugated pipe forming apparatus of a kind of double end.
Background technology
Helical bellows is to be widely used in the various conduit couplings that utilize high temperature that pipeline carries or Low Temperature Liquid, gas such as steam power plant, oil transportation, hot gas, refrigeration supply, its general metal material that adopts is made, the shaped device of the metallic spiral corrugated pipe of existing double end, by embossing cutters such as hobboing cutter or rollers, at pipe two end surfaces rotary press modellings.For product, spinning is directly by routlette, outer surface of tube blank to be carried out the mechanical presses moulding, can't guarantee the process uniformity such as formed product process pitch, the degree of depth, radian according to the wall thickness deviation of pipe in process, simultaneously outer surface of tube blank is carried out mechanical presses formed metal surfaces grain size and metallographic structure changes, therefore the product at place carries out bending use or bend test and can't reach the requirement number of times and will rupture or ftracture after the operations such as annealing are completed.And the shaped device of existing metallic spiral corrugated pipe is by three or more routlette, the processing of straight line back and forth movement to be carried out on the pipe surface, stressed large or three or more routlette of the factors such as the situation pipe decentraction in pipe surface can't disposablely be completed pipe surface of the work is carried out the processing of straight line back and forth movement, need at least twice or repeatedly complete, three or more routlette needs easy to wear are constantly adjusted the mechanical compaction degree of depth and are guaranteed homogeneity of product.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of double end metallic spiral corrugated pipe forming apparatus, and concrete scheme of the present invention is as follows:
The metallic spiral corrugated pipe forming apparatus of a kind of double end comprises two chucks that the position is relative, has the relative sliding stroke between two described chucks; Described chuck is subjected to rotating driving device to drive rotation, and described chuck is provided with the system point boss more than 1 or 1, and described system point boss can stretch vertically.
Preferably, also comprise plug, described plug is between two described chucks.
Preferably, described system point boss can stretch vertically.
Preferably, also comprise feeding device, the output of described feeding device is between two described chucks.
Metallic spiral corrugated pipe forming apparatus provided by the invention, the pipe starting the arc end of turn-knob technique has system point boss, inside has the standard forming plug to guarantee, be equivalent to the pipe extension that stretches according to the extension characteristics of metal, do not change surface of the work and not do not change tubing metal surface grain size and metallographic structure in process, therefore after the operations such as workpiece annealing are completed the product at place carry out bending use or bend test will be higher than service life of traditional handicraft more than 5 times; And this device is not subjected to the constraint of one or more starting the arc spirals, can complete necessary requirement to changing system point boss as requested; Automaticity is high, die change, adjustment are simple.Can complete different tube diameters starting the arc turn-knob technological requirement.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, does not consist of to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is embodiment of the present invention structural representation;
Fig. 2 is embodiment of the present invention system point boss structure schematic diagram.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment:
A kind of metallic spiral corrugated pipe forming apparatus, comprise frame 1, be provided with the first relative chuck 2 of position and the second chuck 3 on the platform of frame 1, the first chuck 2 is connected with a servomotor 4, make described the first chuck 2 be subjected to rotating driving device to drive rotation with servomotor 4 as rotating driving device, the second chuck 3 rotates as rotating driving device with servomotor equally; And the first chuck 2 and the second chuck 3 are located at respectively on slide rail, and drive by propulsion cylinder 5, make between described the first chuck 2 and described the second chuck 3 and have the relative sliding stroke, the first chuck 2 and the second chuck 3 are for clamping pipe two ends, wherein the first chuck 2 and the second chuck 3 are respectively equipped with a shrinkage pool, radially be provided with one or more than one projections in shrinkage pool, form system point boss 21, in the present embodiment, system point boss 21 is three.
When metallic spiral corrugated pipe moulding begins, pipe is placed between the first chuck 2 and the second chuck 3, the two ends of pipe are stretched into respectively in the shrinkage pool of the first chuck 2 and the second chuck 3, and system point boss 21 is conflicted respectively and at the pipe outer wall, this end fixed; By the spacing of adjusting the first chuck 2 and the second chuck 3, pipe is fixed.Start servomotor after pipe is fixing, with pipe turn-knob in the other direction, the starting the arc end of pipe has a system point boss 21 respectively for the first chuck 2 and the second chuck 3, is equivalent to pipe according to the extension of metal and length characteristics and stretches and extend, and pipe forms helical corrugation.Make the corresponding rotating cycle of servomotor adjustment equal the number of turns of spiral; And the quantity of system point boss 21 determines the quantity of parallel helical corrugation, when the quantity of system point boss 21 is one or more, also can determine spacing between helical corrugation by the position of adjustment system point boss 21.
