The manufacturing method is high in working efficiency and applicable to large workpieces with curved hydraulic stretching bolts, and all hydraulic stretching fasteners can be fastened once.
Description
Technical field
The present invention relates to Machining Technology field, relate in particular to a kind of manufacture method of shaped form hydraulic channel.
Background technology
For narrow space and heavy load vibrating machine fastening, adopt hydraulic tensile bolt be one preferably fastening method.The operation principle of hydraulic tensile bolt utilizes hydraulic jack directly to apply external force to bolt, make the bolt of the power that is applied in its elastic deformation (stretching), after bolt is stretched, locking nut is tightened onto on the relevant position of bolt tension length, then makes bolt produce elastic deformation (contraction) by hydraulic cylinder release and reach firm object.Hydraulic cylinder is positioned at the position of bolt axis, for carrying out axial tension to bolt, realizes the amount of tension that bolt needs.And this amount of tension of bolt determines the clamping force needed for bolted just.After hydraulic tensile bolt is pressurizeed by hydraulic coupling, bolt is stretched, and fastening nut and faying face are close to simultaneously.Thus the axial deformation of bolt is locked.
Existing hydraulic tensile bolt assembly method mainly contains two kinds; One is the single hydraulic tensile bolt of assembling, as valve seat and the valve gap of the input and output material valve on Large-scale High-Pressure membrane pump, can only one one assembling hydraulic tensile bolt, the workpiece that the method i.e. applicable hydraulic tensile bolt difformity applied widely is arranged, but operating efficiency is low; Two is by the disposable fastening all hydraulic tensile bolt of linear hydraulic channel, and the method adopts the mode of boring to produce linear hydraulic channel, once fastening all hydraulic tensile bolt, as; The valve seat of the input and output material valve on minitype high voltage membrane pump and valve gap, first on valve gap, get out linear hydraulic channel, then once fastening all hydraulic tensile bolt, although work efficiency improves greatly, but drill bit is straight and limited length, cause linear hydraulic channel not long, hydraulic tensile bolt can only be applicable to and be arranged as linear and be small-sized workpiece.For large-scale, hydraulic tensile bolt is arranged as curved workpiece (as ring flange), just cannot realize once assembling all hydraulic tensile bolt, thus the utilization of hydraulic fastening is restricted greatly.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of operating efficiency provided is high, can realize once fastening all hydraulic tensioning securing members, be applicable to large-scale, hydraulic tensile bolt is arranged as the manufacture method of the shaped form hydraulic channel of curved workpiece.
The manufacture method of a kind of shaped form hydraulic channel of the present invention, comprises the following steps:
(1) hydraulic pressure foundation trench processing; Workpiece blank processes hydraulic pressure foundation trench;
(2) sunken cord: pre-buried nonmetallic materials in groove;
(3) weld: adopt built-up welding to close the foundation trench of pre-buried nonmetallic materials, be welded to workpiece blank original-shape;
(4) welding stress is eliminated; Built-up welding is conventional insulation annealing elimination welding stress after closing;
(5) processing work: the shape and the size that process workpiece by design, get out required bolt hole, cut off welding stress;
(6) hydraulic channel is formed; In bolt hole, nonmetallic materials pre-buried in hydraulic pressure foundation trench are removed, forming curves shape hydraulic channel after boring.
The manufacture method of above-mentioned a kind of shaped form hydraulic channel, wherein: nonmetallic materials at high temperature volume energy reduce.
The manufacture method of above-mentioned a kind of shaped form hydraulic channel, wherein: nonmetallic materials are asbestos.
The manufacture method of above-mentioned a kind of shaped form hydraulic channel, wherein: shaped form hydraulic channel also can be long linear.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: the present invention processes hydraulic pressure foundation trench on the position workpiece blank arranging hydraulic tensile bolt, adopt the mode of sunkening cord that nonmetallic materials are embedded in bottom land, the mode of built-up welding is adopted at nonmetallic materials upper surface, foundation trench is closed in blank original-shape, eliminates welding stress with the original performance of restorer.Then required workpiece shapes is processed into; get out required bolt hole and both meet design needs; also radial stress can be cut off again to eliminate welding stress; removed the nonmetallic materials reducing (as: particle or Powdered) through welding high temperature lower volume of pre-reason by this hole simultaneously; to form hydraulic channel, this hydraulic channel can be shaped form also can be long linear.The present invention is not by the restriction of bolt arrangement shape, and can realize once fastening all hydraulic tensile bolt, operating efficiency is high, is applicable to large-scale, and hydraulic tensile bolt is arranged as the workpiece of curve or long straight shape, thus applied widely.
