Abstract

The utility model relates to a molding device of metal spiral corrugated pipes. The molding device comprises a first chuck and a second chuck, positions of the first chuck and the second chuck are opposite, a relative sliding stroke is arranged between the first chuck and the second chuck, the first chuck is driven by a rotation driving device to rotate, and one or more than one control point bosses are arranged on the first chuck. In the molding device of the metal spiral corrugated pipes, service life of a pipe blank in a turn-knob process is 5 times longer than that in a traditional process when bending use or a bend test is carried out on products after working procedures such as annealing is completed. The molding device is not limited by one or a plurality of arcing screws, can complete needed requirements by changing the control point bosses according to requirements, is high in degree of automation and simple in die changing and adjustment, and can meet process requirements for arcing turn-knobs with different pipe diameters.

Description

A kind of metallic spiral corrugated pipe forming apparatus
Technical field
The utility model 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 embossing cutters 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 the mechanical presses moulding, wall thickness deviation according to pipe can't guarantee the process uniformity such as formed product process pitch, the degree of depth, radian 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 finished.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 three or more routlette of the factors such as situation large or the pipe decentraction in pipe surface can't disposablely be finished pipe surface of the work is carried out the processing of straight line back and forth movement, need at least twice or repeatedly finish, three or more routlette needs easy to wear are constantly adjusted the mechanical compaction degree of depth and are guaranteed homogeneity of product.
The utility model content
Primary and foremost purpose of the present utility model is to provide a kind of metallic spiral corrugated pipe forming apparatus, and concrete scheme of the present utility model is as follows:
A kind of metallic spiral corrugated pipe forming apparatus comprises the first chuck and the second chuck that the position is relative, has the relative sliding stroke between described the first chuck and described the second chuck; Described the first chuck is subjected to rotating driving device to drive rotation, and described the first chuck is provided with the system point boss more than 1 or 1.
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.
The metallic spiral corrugated pipe forming apparatus that the utility model provides, 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 the product at place carries out the bending use or bend test will be higher than the service life of traditional handicraft more than 5 times after the operations such as workpiece annealing are finished; And this device is not subjected to the constraint of one or more starting the arc spirals, can finish necessary requirement to changing system point boss as requested; Automaticity height, die change, adjustment are simple.Can finish different tube diameters starting the arc turn-knob technological requirement.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment system point boss structure schematic diagram.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment:
A kind of metallic spiral corrugated pipe forming apparatus, comprise frame 1, platform in frame 1 is provided with the first relative chuck 2 of position and the second chuck 3, the first chuck 2 also is connected with a servomotor 4, makes described the first chuck 2 be subjected to rotating driving device to drive rotation with servomotor 4 as rotating driving device; And the first chuck 2 and the second chuck 3 are located at respectively on the slide rail, and by propulsion cylinder 5 drivings, 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 used for clamping pipe two ends, wherein the first chuck 2 is provided with a shrinkage pool, radially be provided with one or more than one projections in the shrinkage pool, form system point boss 21, system point boss 21 is three in the present embodiment.
When metallic spiral corrugated pipe moulding begins, pipe is placed between the first chuck 2 and the second chuck 3, an end of pipe stretches in the shrinkage pool of the first chuck 2, and system point boss 21 is conflicted respectively and at the 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 present embodiment is not being repeated.Start after pipe is fixing servomotor 4, the first chucks 2 with pipe around axle veer turn-knob, the starting the arc end of pipe has a system point boss 21, is equivalent to pipe according to the extension of metal and length characteristics and stretches and extend, 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 be one or more, also can determine spacing between the helical corrugation by the position of adjusting a system 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, passes the second chuck 3 starting the end of servomotor 4 money with 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 the turn-knob process is not crooked, and guarantee that the 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 this moment system point boss 21 and the first chuck, and be provided with in advance through hole in the adaptation position of pipe after one end of pipe stretches into the shrinkage pool of the first chuck 2, are made in the through hole that a boss 21 stretches into pipe this end are 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.Continuous automatic production by above-mentioned improvement project implement device.
