Abstract
The utility model provides a wave pipe processing apparatus and is mainly composed of a liquid pressing mechanism and a multiple station flexible mould tool. The mould tool is formed by stacking a plurality of circular ring sub-mould plates with grooves arranged on the inner walls of the mould plates. The one time forming of a plurality of wave nodes can be achieved. The wall thickness is uniform and the wave shape is uniform. The wave pipe processing apparatus has the advantages of high quality, simple equipment, easy control, low cost and low processing cost.
Description
The utility model belongs to mechanical field, relates to a kind of bellows processing unit (plant) of bellow-type expansion joint.
Bellow-type expansion joint mainly is made up of bellows, joint design and annex.The wherein processing of bellows has three kinds of methods both at home and abroad usually, i.e. spinning method, hydraulic method and spinning liquid combination method, and usefulness is the first two kind at most.Spinning method control system complexity, cost an arm and a leg.Because spinning process medium wave wall part is thinned, the emersion wave wall is burnt sometimes, and spinning produces additional stress, so product is unreliable, easily causes to break during use to cause damage.Hydraulic method is a fixed mould, and cylindrical shell is in next ripple one rolling land moulding piecemeal (seeing Fig. 5-1) of ton water hydraulic press effect.When compacting second ripple, though first ripple is molded but still stressed, this just causes down ripple, and the waveform inequality also influences product quality.
The purpose of this utility model is to provide a kind of bellows processing unit (plant), can be shaped, be easy to control by once many ripples, improves the quality of products.
The utility model is achieved through the following technical solutions: mainly form the bellows processing unit (plant) by hydraulic mechanism and mould.Hydraulic mechanism comprises column, connects top board, way station and the workbench of column, and vertically is installed on the hydraulic cylinder between top board and the way station.Mould is the multistation flexible mould, and by the reeded circular subtemplate of polylith inwall stacking composition, adjacent subtemplate closure just in time constitutes a node.Have locating hole on the subtemplate, in order to be serially connected on the sliding axle.
The utility model is described in further detail below in conjunction with an embodiment of the present utility model.
Fig. 1 is an embodiment of the present utility model.Fig. 2, Fig. 3 are respectively the schematic diagrames that mould 2 is in initial station and termination station.Column 1, workbench 4, top board 7, way station 8 are pieced together system by shaped steel, and hydraulic cylinder 6 is 4 groups of hydraulic jacks.In the two-terminal template 21 of mould 2, the 2n groove opposite is arranged respectively, the groove of 2 symmetries is respectively arranged in all the other dynatron templates.The crest of proper corresponding each node of bellows in maximum gauge place of each groove, the trough of the proper corresponding bellows in minimum diameter place of groove.All subtemplates are by 2 guide rods, 9 location, and subtemplate can slide up and down along guide rod 9.
During this equipment of use, processed ripple tube core tube material 3 and mould 2 are positioned on the workbench 4.Adjust mould 2 to initial station.Have a distance between each subtemplate this moment, and the interior corresponding ripple tube core tube length of this segment distance is the length of a wave spread just.Add interior pressure by interior pressure capstan 5.This moment, core tube material began distortion, because each section deflection is consistent, the distance between each subtemplate keeps equating in whole process.Pressure is passed through oil cylinder 6 along core tube material axial pressure after reaching certain value in (consulting Fig. 4), progressively is forced into the termination station, and bellows is a completion of processing.
When the utility model was pressed in initial station adds, each ripple deflection was consistent, progressively all was in same operating mode to stopping station from initial station, thereby each wave-wave shape unanimity, and wall thickness is even, and the attenuate amount is very little.The utility model adopts market universal product hydraulic jack, and simple in structure, assembling, control all are easy to, and cost and product processing charges reduce greatly than known technology.
