Abstract

The invention relates to a metal helical bellows forming device which comprises a first chuck and a second chuck, wherein the position of the first chuck and the position of the second chuck are opposite to each other. A relative sliding travel is arranged between the first chuck and the second chuck. The first chuck rotates under the driving of a rotation driving device, and the first chuck is provided with one or more critical control point bosses. According to the metal helical bellows forming device, after annealing and other procedures are completed on tube blanks of a twisting process, the products are used for bending or bending tests, and the service life can be more than five times of that of a traditional process. The metal helical bellows forming device is free of constraint of one or more arc striking spirals, and the critical control point bosses can be replaced according to requirements to complete needs. The metal helical bellows forming device is high in automation degree, simple in model replacement and adjustment, and capable of meeting technological requirements of arc striking and twisting of tubes with different diameters.

Description

A kind of metallic spiral corrugated pipe forming apparatus
Technical field
The present invention relates to a kind of metallic spiral corrugated pipe forming apparatus.
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 existing metallic spiral corrugated pipe, by routlettes such as hobboing cutter or rollers, at pipe surface rotary press modelling.For product, spinning is directly by routlette, outer surface of tube blank to be carried out to mechanical presses moulding, according to the wall thickness deviation of pipe, cannot in process, guarantee the process uniformity such as formed product process pitch, the degree of depth, radian, outer surface of tube blank is carried out to mechanical presses formed metal surfaces grain size and metallographic structure changes, therefore after the operations such as annealing complete, the product at place carries out bending use or bend test and cannot reach requirement number of times and will rupture or ftracture simultaneously.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 is carried out in pipe surface, stressed three or more routlette of the factors such as situation large or pipe decentraction in pipe surface cannot disposablely complete pipe surface of the work is carried out to 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 metallic spiral corrugated pipe forming apparatus, and concrete scheme of the present invention is as follows:
A pipe forming apparatus, comprises the first chuck and the second chuck that position is relative, between described the first chuck and described the second chuck, has relative sliding stroke; Described the first chuck is subject to rotating driving device to drive rotation, and described the first chuck is provided with 1 or 1 above system point boss.
Preferably, also comprise plug, described plug is between described the first chuck and described the second chuck.
Preferably, described system point boss can stretch vertically.
Preferably, also comprise feeding device, the output of described feeding device is between described the first chuck and described the second chuck.
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 standard forming plug to guarantee, according to the extension feature of metal, be equivalent to the pipe extension that stretches, in process, do not change surface of the work and not do not change tubing metal surface grain size and metallographic structure, therefore after the operations such as workpiece annealing complete, the product at place carries out bending use or bend test by the service life higher than traditional handicraft more than 5 times; And this device is not subject to the constraint of one or more starting the arc spirals, can to changing system point boss, complete necessary requirement as requested; Automaticity is high, die change, adjustment are simple.Can complete different tube diameters starting the arc turn-knob technological requirement.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms the application's a part, does not form inappropriate limitation 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
Below in conjunction with accompanying drawing and specific embodiment, describe the present invention in detail, in this illustrative examples of the present invention and explanation, be used for explaining the present invention, but not as a limitation of the invention.
Embodiment:
A kind of metallic spiral corrugated pipe forming apparatus, comprise frame 1, on the platform of frame 1, be provided with the first relative chuck 2 of position and the second chuck 3, the first chuck 2 is also connected with a servomotor 4, and the servomotor 4 of usining makes described the first chuck 2 be subject to rotating driving device to drive rotation as rotating driving device; And the first chuck 2 and the second chuck 3 are located at respectively on slide rail, and drive by propulsion cylinder 5, make to there is relative sliding stroke between described the first chuck 2 and described the second chuck 3, the first chuck 2 and the second chuck 3 are for clamping pipe two ends, wherein the first chuck 2 is provided with a shrinkage pool, in shrinkage pool, be radially provided with one or more than one projections, form system point boss 21, in the present embodiment, system point boss 21 is three.
When metallic spiral corrugated pipe moulding starts, pipe is placed between the first chuck 2 and the second chuck 3, one end of pipe is stretched in the shrinkage pool of the first chuck 2, and system point boss 21 is conflicted respectively and at pipe outer wall, this end fixed; By adjusting the spacing of the first chuck 2 and the second chuck 3, the pipe other end is fixing with the second chuck 3, and the fixing of the second chuck 3 can adopt various ways, and the present embodiment is not being repeated.After pipe is fixing, start servomotor 4, the first chucks 2 by pipe around axle veer turn-knob, the starting the arc end of pipe has a system point boss 21, is equivalent to pipe stretches and extend according to the extension of metal and length feature, pipe forms helical corrugation.Make servomotor 4 adjust the number of turns that corresponding rotating cycle equals 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 the spacing between helical corrugation by the position of adjustment system point boss 21.
Improvement as above-described embodiment scheme, also comprise plug 6, described plug 6 is located at slide rail top and is advanced by cylinder 5, at startup servomotor 4 money, the second chuck 3 is passed in one end of plug 6, makes plug 6 between described the first chuck 2 and described the second chuck 3.By above-mentioned improvement project, guarantee that pipe integral body in turn-knob process is not crooked, and guarantee that pipe internal diameter is consistent, avoid stopping up.
As the improvement of above-described embodiment scheme, described system point boss 21 can stretch vertically.2 one-tenths split-type design of system point boss 21 and the first chuck now, and be provided with in advance through hole in the adaptation position of pipe, one end of pipe is stretched into after the shrinkage pool of the first chuck 2, makes to put in the through hole that boss 21 stretches into pipe this end is fixed.
As the improvement of above-described embodiment scheme, also comprise feeding device 7, the output of described feeding device 7 is between described the first chuck 2 and described the second chuck 3.By the continuous automatic production of above-mentioned improvement project implement device.
