It includes：Compression is stifled, top is stifled, gasket, pipe plug opening, and top is stifled to be passed to compression by packing torque by the cooperation of pipe plug opening connection screw thread and block up,
Compression is stifled to realize sealing, therefore the sealing surface one and sealing surface two of pipe plug opening between pipe plug opening sealing surface using gasket flexible deformation
Carry entire Twin-plug sealing structure.
Compared with monofilament bridging structure, Twin-plug structure pipe plug opening is relative complex, to process 2 sealing surfaces, usual Twin-plug
Structure pipe plug opening procedure of processing includes：Bottom outlet processing, thread Pilot hole processing, bottom outlet reaming, sealing surface processing, sealing surface are blocked up in compression
The process of chamfering, pipe plug opening outer chamfered, a pipe plug opening will at least replace No. six cutters, and each air cooler bobbin carriage is extremely
A pipe plug openings up to a hundred are processed less, if according to said method manufacturing, the process-cycle will be grown, and by multiple replacement, adjustment cutter, meeting
Cutter tolerance itself is brought into processing, through fit tolerance between cumulative limit influence silk plug pore size, reduces product qualification rate, shadow
Ring the sealing effect of pipe plug opening.
Invention content
To solve the above-mentioned problems, the purpose of this utility model is to provide one kind for processing Twin-plug sealing structure silk
The compound tool of plug-hole.
What the purpose of this utility model was realized in：A kind of composite cutter for processing Twin-plug sealing structure pipe plug opening
The different location of tool, including cutter hub and seven blades, the cutter hub is provided with seven insert grooves, is fixedly mounted in each insert groove
There is blade, respectively in the setting of the position of each blade there are one corresponding coolant drain mouth, the cutter hub internal axis is set
It is equipped with the hopper for coolant flow, the cutter hub bottom is provided with inlet, and the inlet is connected to the hopper,
Coolant liquid is entered by inlet in cutter, is sent to seven coolant drain mouths via hopper, to each corresponding knife
Piece is cooled down, and the first chip space, the second chip space and third chip space, the second blade, third are provided on the cutter hub
Generated scrap is discharged by the first chip space at work for blade, fourth blade and the 5th blade, and the 7th blade is working
When generated scrap be discharged by the second chip space, the first blade and the 6th blade at work caused by scrap pass through the
Three chip spaces are discharged.
5 ° of knife swing angles are formed between second blade as described above, third blade and fourth blade.
5 ° of knife swing angles are formed between first blade and the 6th blade as described above.
Compared with prior art, the effect and benefit of the utility model are：The compound tool of the utility model, both reduced
It replaces, debug cutter and programming time, and reduce the cutter null time, substantially increase production efficiency, knife is formed between blade
Swing angle forms certain chip space, is cut so that blade is disconnected, prevents iron from cutting and twines knife to Cutting Tool Damage, since size is integrated, it is only necessary to right
One tool dimension tolerance is controlled, and pipe plug opening machining accuracy is improved, and ensure that the sealing effect of pipe plug opening.

Embodiment 1
In conjunction with shown in Fig. 1-4, a kind of compound tool for processing Twin-plug sealing structure pipe plug opening, including 8 He of cutter hub
The different location of seven blade 1-7, the cutter hub 8 are provided with seven insert grooves, and installation is screwed in each insert groove
There is blade, respectively in the setting of the position of each blade there are one corresponding coolant drain mouth, 8 internal axis of the cutter hub is set
It is equipped with the hopper 10 for coolant flow, 8 bottom of the cutter hub is provided with inlet 9, the inlet 9 and the hopper
10 connections, coolant liquid are entered in cutter by inlet 9, are sent to seven coolant drain mouths, to each via hopper 10
Corresponding blade is cooled down, and the first chip space 12, the second chip space 13 and third chip space are provided on the cutter hub 8
14, generated scrap passes through the first chip space at work for the second blade 2, third blade 3, fourth blade 4 and the 5th blade 5
12 discharges, generated scrap is discharged the 7th blade 7 by the second chip space 13 at work, the first blade 1 and the 6th blade 6
Generated scrap is discharged by third chip space 14 at work.
5 ° of knife swing angles are formed between the second blade 2, third blade 3 and fourth blade 4 described in the present embodiment.
The first blade 1 described in the present embodiment and 5 ° of knife swing angles of formation between the 6th blade 6.
The utility model is in use：The present apparatus and operating parts are fixed first, the first blade 1 and the second blade 2
