Description
Technical field
The utility model relates to the device for cutting pipe or Pipe Cutting, espespecially a kind of nozzle equating tooling.
Background technique
When refrigeration pipeline connects at present, line end is cut using cutter, and nozzle end can will appear necking in various degree
Phenomenon.Engineering is in practice, it is desirable that line end is straight, cannot there is necking.Existing solution is flared using dedicated pipeline
Tool is flared line end, eliminates necking.But in actual use, flaring tool itself not can guarantee after amendment necking outside pipeline
Diameter remains unchanged.Flaring process fully relies on operator using strength size, and due to not having tooling guarantee, pipeline is eliminating necking
While, outer diameter can also expand, and outer diameter is greater than actual requirement size, not be available.It needs to cut again, then again to pipe
Road endgame correction, wastes time, and wastes material, influences project progress.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of nozzle equating toolings.Cooperation flaring
Tool is flared line end, eliminates necking, guarantees pipeline while eliminating necking, outer diameter will not expand.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of nozzle equating tooling is provided, it is special
Sign is: including working base and several nozzle trimming heads being mounted on working base, the nozzle trimming head has the two-section frustum of a cone
Inner hole, the coning angle of the first frustum of a cone inner hole are 420±20, the coning angle of the second frustum of a cone inner hole is 20±0.20。
The nozzle trimming head is in open circles frustum structure, and the cone angle of outer circle frustum is 140±20。
The beneficial effects of the utility model are: cooperation flaring tool is flared line end, necking is eliminated, guarantees that pipeline exists
While eliminating necking, outer diameter will not expand.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.

In figure: 1 being nozzle trimming head, 11 be the first frustum of a cone inner hole, 12 be the second frustum of a cone inner hole, 2 be working base, 3
It is flaring tool for workpiece tube (pipe to be modified), 4.
Specific embodiment
Referring to Fig. 1 Fig. 2, a kind of nozzle equating tooling of the utility model, it is characterised in that: including working base 2 and be mounted on
Several nozzle trimming heads 1 on working base 2, referring to Fig. 3, the nozzle trimming head 1 has a two-section frustum of a cone inner hole 11,12, and first
The coning angle of frustum of a cone inner hole 11 is 420±20,Optimum value is 420(frustum of a cone inner hole shown in Fig. 3 is equivalent to when actual measurement
11 bus and the supplementary angle of baseline angle are 1120), the coning angle of the second frustum of a cone inner hole 12 is 20±0.20Optimum value is 20
(supplementary angle of bus and baseline angle that frustum of a cone inner hole 12 shown in Fig. 3 is equivalent to when actual measurement is 910).
In the embodiments of the present invention:
The nozzle trimming head 1 is in open circles frustum structure, and the cone angle of outer circle frustum is 140±20, optimum value 140It is (real
Border is equivalent to frustum of a cone outer cone bus shown in Fig. 3 and the supplementary angle of baseline angle when measuring be 970).
The diameter at butt end B of first frustum of a cone inner hole 11 is greater than the outer diameter of workpiece tube 3, to facilitate the insertion of workpiece tube 3；The
Top diameter (diameter at butt end of the second frustum of a cone inner hole 12) C of one frustum of a cone inner hole 11 is slightly larger than the outer diameter of workpiece tube 3,
Workpiece tube 3 is filled in largest extension diameter range perhaps, and the top diameter D of the second frustum of a cone inner hole 12 is equal to the outer of workpiece tube 3
Diameter.Make workpiece tube 3 in tube expansion tool makeover process, outer wall is expanded in controllable range.1 outer circle wimble structure of nozzle trimming head
It is fixed on nozzle trimming head 1 conveniently in working base 2, replacement easy to disassemble.
The alloy that the hardness of nozzle trimming head 1 is higher than workpiece tube 3 makes, and reaching can support intensity when pipeline tube expansion to want
It asks.
Referring to fig. 4, the pipe section figure before amendment, the end 31 of pipeline is with the presence of necking.
When use:
Referring to Fig. 6, workpiece tube 3 is inserted into from 11 major part of the first frustum of a cone inner hole of nozzle trimming head 1, in place after, will be flared
Tool 4 is inserted into from 1 second frustum of a cone inner hole of nozzle trimming head, 12 microcephaly, is close to workpiece pipe end, carries out and complete to manage according to conventional
Mouth equating.
Referring to Fig. 7,3 outer wall of workpiece tube is tightly fitted on the inner wall of nozzle trimming head 1, and necking amendment is completed
Referring to Fig. 5, revised 3 sectional view of workpiece tube, pipeline is straight, and necking is eliminated.
In the embodiments of the present invention, nozzle trimming head 1 shares 5, corresponding copper pipe nominal size 6.35,
9.52,12.7,15.9,19.1, it is embedded in working base 2.
The size of corresponding A, B, C, D are as shown in the table under above-mentioned size.
