Description
Technical field
The present invention relates to a kind of processing technology, particularly relate to the processing technology of a kind of active installing plate being used in thermal vacuum test case.
Background technology
Seeing Figure of description 2 to accompanying drawing 4, shown structure is modular construction and the inner passage layout of active installing plate, existing active installing plate processing technology substantially:
1, welding red copper pipe on copper plate；
2, the workpiece after welding polishes, and is machined to the size needed；
3, follow-up parts weld, assemble, detection etc..
This processing mode has the disadvantage in that
1. welding rear surface deflection is big；
2. Surface Machining difficulty is high；
The most active installing plate main body be red copper be that soft metal, surface and bulk strength are low；
The most cold and hot deflection is big；
5. at the bottom of cost height, yield rate.
Summary of the invention
Because the drawbacks described above of prior art, active installing plate processing technology that the technical problem to be solved is to provide processing a kind of low cost, easy, that yield rate is high.
For achieving the above object, the invention provides a kind of active installing plate processing technology, comprise the steps:
S1: blanking, size cuts out the profile blank of active installing plate on stainless steel as desired；
S2: four sides smoothing, i.e. smooths side, left surface, right flank before and after the active installing plate blank after cutting；
S3: drilling deep hole, is fixed on the active installing plate after smoothing in frock, then uses deep hole rig to face right flank positive direction to the left and gets out through hole；
S4: bore fixing hole: towards bottom surface positive direction, the active installing plate after drilling deep hole is got out fixing hole at end face, and described fixing hole can not intersect with deep hole；
S5: install bracing frame, is fixed on active installing plate on bracing frame through fixing hole and support frame aperture with screw；
S6: weld out pipe and header, first choose diameter more than or equal to deep hole diameter go out pipe and header, the opening consistent with deep hole quantity is had on described header, then the one end going out pipe is welded on each deep hole be welded on header opening at left surface, the outlet of right flank, the other end that each goes out pipe the most again；
S7: high pressure and vacuum inspection leakage, carry out high pressure and vacuum leak hunting to the active installing plate after having welded out pipe and header；
S8: secondary operations, i.e. polishes to the end face of active installing plate；
Further, after smoothing, each plane parallelism reaches 0.5；
Further, in S1, when choosing stainless steel materials, the most at least to reserve the allowance of 2；
Further, in S3, should be to determine the position in hole on the basis of bottom surface during boring；
Further, the leak detection of S7 mesohigh uses bubble method or Special leakage detector leak detection, and vacuum leak hunting uses precision higher than 1*10-10Pa.m3The vacuum leak detector leak detection of/s, the leak rate of vacuum leak hunting should be less than 1*10-9Pa.m3/s；
Further, in S8, after end face polishing, its flatness reaches 0.05mm/20cm2, fineness reaches 0.8.
The invention has the beneficial effects as follows:
The most active installing plate material is stainless steel, and intensity is high, good processability；
The most active installing plate central bore increases as refrigerating medium runner, heat exchange area, improves heat transfer effect；
3. welding capacity is few, only welds fairlead at end face, and owing to have employed argon arc welding, active installing plate thermal deformation is little；
The complete rear secondary operations of the most active installing plate integral solder is convenient, can ensure its flatness and fineness very well；
5. stainless steel deflection in cold and hot change procedure is less than red copper, and therefore in the most cold and hot change procedure, the less property indices of deformation meets use requirement all the time.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
As shown in Figure 1 to Figure 3, a kind of active installing plate processing technology, including following procedure of processing:
S1: blanking, choose SUS304 corrosion resistant plate, according to the size of 600mm*800mm, the profile blank of active installing plate 1 in cutting out such as Fig. 3 on the SUS304 corrosion resistant plate that thickness is 16mm, selected corrosion resistant plate is at least than demand thickness thick 2, as reserved allowance；
S2: four sides smoothing, by side before and after the active installing plate 1 after S1 process, left surface 15, right flank 16 are smoothed, and after smoothing, each plane parallelism reaches 0.5；
S3: drilling deep hole, sees the active installing plate 1 after Fig. 3 will smooth and is fixed in frock, then uses deep hole rig face 15 to the left towards the deep hole 12 getting out 18 a diameter of 8mm in right flank 16 positive direction；Should be to determine the position of deep hole on the basis of bottom surface 14 during boring；
S4: bore fixing hole: by the active installing plate after drilling deep hole at its end face towards getting out the fixing hole 11 of needs in the positive direction of bottom surface, described fixing hole 11 can not intersect with deep hole 12；
S5: install bracing frame, i.e. through fixing hole 11 and support frame aperture, active installing plate 1 is fixed on bracing frame 2 with screw；
S6: weld out pipe and header, first the header 3 going out pipe 4 and a diameter of 22 that diameter is identical with deep hole diameter is chosen, the opening consistent with deep hole 12 quantity is had on described header 3, then the one end going out pipe 4 is welded on two outlets of each deep hole 12, and the other end that each goes out pipe 4 the most again is welded on the opening of header 3；
S7: high pressure and vacuum inspection leakage, be put into the active installing plate 1 having welded out pipe 4 and header 3 and carry out high pressure and vacuum leak hunting；High pressure leak detection uses bubble method or Special leakage detector leak detection, vacuum leak hunting employing precision higher than 1*10-10Pa.m3The vacuum leak detector leak detection of/s, the leak rate of vacuum leak hunting should be less than 1*10-9Pa.m3/s。
S8: secondary operations, polishes the end face 13 of active installing plate 1 as working face so that it is flatness reaches 0.05mm/20cm2, fineness reaches 0.8.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
