Specific embodiment
Prolong accurately to control the enamel thickness of cutting of enamel pipe fitting to improve the corrosion resistance of enamel pipe fitting
Its long service life, the embodiment of the invention provides a kind of enamel cutting tools for enamel pipe fitting.It is of the invention to make
Purposes, technical schemes and advantages are clearer, and invention is further described in detail by the following examples.
As shown in Figure 1, the enamel inner container 2 of water heater usually enamel pipe fitting 1 of the connection one for being connect with exterior line,
The end side that enamel pipe fitting 1 is connect with enamel inner container 2 has stepped inner walls, and stepped inner walls include annular flat face 11 and and ring
The hole wall portion 12 that shape planar portions 11 connect.
In the prior art, when covering processing to enamel pipe fitting progress porcelain, the enamel thickness at stepped inner walls is difficult to control,
Enamel is blocked up, will lead to assembly difficulty, and enamel is excessively thin, then easily leak occurs because corrosion is pierced by.
As shown in Figures 1 to 4, the enamel cutting tool 3 for enamel pipe fitting 1 that one embodiment of the invention provides, is warded off
The end side that porcelain tube connector 1 is connect with enamel inner container 2 have stepped inner walls, stepped inner walls include annular flat face 11 and with annular
The hole wall portion 12 of 11, plane connections, enamel cutting tool 3 include sequentially connected turning handle 31, limiting section 32,33 and of positioning column
Cutting portion 34, in which:
Limiting section 32 can be limited in the end of enamel pipe fitting 1, and positioning column 33 and the inner tube wall of enamel pipe fitting 1 are coaxial
Positioning assembly, cutting portion 34 include the first bite 341 suited with facial 11 phases of annular flat and suit with 12 phase of hole wall portion
The second bite 342.
The application method of the above embodiment of the present invention enamel cutting tool 3 are as follows:
Enamel cutting tool 3 is inserted into enamel pipe fitting 1, limiting section 32 is made to be limited in the end of enamel pipe fitting 1, it is fixed
The inner tube wall of position column 33 and enamel pipe fitting 1 coaxially positions assembly, at this time the planar annular of the first bite 341 and stepped inner walls
11 phase of portion suits, and 12 phase of hole wall portion of the second bite 342 and stepped inner walls suits；
The turning handle 31 of enamel cutting tool 3 is rotated, the first bite 341 is to the annular flat faces 11 of stepped inner walls at this time
Enamel is cut, and the second bite 342 cuts the enamel of the hole wall portion 12 of stepped inner walls, when enamel cutting tool 3
When idle running, show that enamel thickness is adjusted to ideal thickness, enamel cutting tool 3 can be taken out from enamel pipe fitting 1.
The enamel of 1 stepped inner walls of enamel pipe fitting is cut using the enamel cutting tool 3 of the above embodiment of the present invention
When cutting, with the rotation of enamel cutting tool 3, the first bite 341 carries out the enamel of the annular flat face 11 of stepped inner walls
Cutting, the second bite 342 cuts the enamel of the hole wall portion 12 of stepped inner walls, since limiting section 32 is limited in enamel pipe
The inner tube wall of the end of connector 1, positioning column 33 and enamel pipe fitting 1 coaxially positions assembly, therefore the insertion of enamel cutting tool 3
Depth is constant and rotates always around same rotation axis, so as to accurately control the thickness of cutting of enamel, after making cutting
Enamel consistency of thickness.
As shown in Figure 3 and Figure 4, in the preferred embodiment, it the first bite 341 at least two and is positioning
End side of the column 33 far from limiting section 32 is uniformly distributed in circumferential.Using the design, the enamel of aforementioned toroidal planar portions 11 can be made
It uniformly and is rapidly cut, and the stress of enamel cutting tool 3 is also more uniform, to be conducive to extend service life.
Further, the first bite 341 uses triangle cutter tip, and the cutting edge 34a of triangle cutter tip is along fixed
Position column 33 radially extends.Triangle cutter tip stabilized structure, hardness is higher, is unlikely to deform, so as to further extend
The service life of enamel cutting tool 3.
As shown in figure 4, the second bite 342 be along positioning column 33 the blade being arranged radially, blade include respectively with it is preceding
State two cutting edges 34b, 34c that wall portion 12 phase in hole suits.When enamel cutting tool 3 rotates, two cutting edges 34b, 34c are same
When device to hole wall portion 12 cut, stock-removing efficiency is higher, and the second bite 342 also can uniform stressed, so as into
The service life of one step extension enamel cutting tool 3.In addition, blade design is in long ligule, there is guiding role, cut convenient for enamel
Cutting knife tool 3 is inserted into enamel pipe fitting 1 and stretches out hole wall portion 12, reduces the collision to 3 inner wall of enamel pipe fitting.
The specific constructive form of turning handle 31 is unlimited, such as cross-sectional shape can be designed as round, rectangular, triangle or six
Side shape, etc..In addition, turning handle 31 may be designed in other shapes convenient for rotation process.
For the ease of rotation process turning handle 31, it is preferred that turning handle 31 has coarse non skid matting.As shown in figure 3, at one
In alternative embodiment, 31 surface of turning handle has annular knurl 311.In the other alternative embodiment of the present invention, turning handle surface can also be with
With rubber sleeve, to play the antiskid effect for increasing friction.
When the first bite 341 is using triangle cutter tip, preferably, turning handle 31, limiting section 32,33 and of positioning column
First bite 341 is structure as a whole, and structural strength is higher, can further extend the service life of enamel cutting tool 3, and
And cost of manufacture is also relatively low.
As shown in figure 5, enamel cutting tool 3 may also include for driving turning handle 31 in alternative embodiment of the invention
The driving device 4 of rotation, driving device 4 can be using hand drills etc., in this way, manpower can be saved, stock-removing efficiency is higher.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
