Summary of the invention
The technical problem to be solved by the present invention is to be directed to the status of the prior art, a kind of glass tube cutting method is provided, is adopted
With new glass tube cutting method, have easy to operate, cutting cost is low.
The technical scheme of the invention to solve the technical problem is: a kind of glass tube cutting method, feature exist
In, comprising the following steps:
Step S1 pours into cooling liquid in container；
Glass tube to be cut is inserted into container by step S2, and the upper surface of cooling liquid is wrapped in glass tube side wall,
Cooling liquid upper surface and glass tube side wall intersection are formed at cutting trace；
Step S3 instills conduction oil above cooling liquid in container, stands a period of time, and the density of conduction oil is less than cold
But liquid, conduction oil uniformly diffuse to form one layer of oil film in cooling liquid upper surface, and conduction oil covering is cut at trace；
Step S4, by the oil film of the heat-conducting metal insertion conduction oil of heating, oil film is heated quickly, and the heat of oil film passes
It being handed at the cutting trace of glass tube, temperature of the glass tube at cutting trace rises rapidly, meanwhile, in the intracorporal glass of coolant liquid
Glass pipe lower temperature is lower, and glass tube generates concentrated stress at cutting trace, and under the effect of expanding with heat and contract with cold, glass tube is being cut
It is broken at trace.
Preferably, the cooling liquid is water.
Preferably, the conduction oil is edible oil.
As an improvement, in the step S2, before cooling liquid is inserted into glass tube lower end, in the lower end of glass tube
A pouring weight is hung, by the way that pouring weight is arranged, when generating concentrated stress at the cutting trace of glass tube, glass tube is by pouring weight one
The active force pulled down, consequently facilitating glass tube is broken at cutting trace.
It improves again, in the step S2, glass tube is inserted into an inclined manner in coolant liquid body, in this way, cooling liquid
The cutting trace of formation is ellipse, and it is inclined for finally making the notch of glass tube.
It improves again, the outside of the container is vertically provided with a column, and sliding is provided with bracket on column, rotates on bracket
It is provided with a support plate, scale is provided in support plate, the collet for clamping glass tube is provided in support plate.In installation glass
Bracket is moved up when glass pipe, moves down bracket after being installed, glass tube lower end and cooling liquid upper surface contact, rotation
Support plate changes the tilt angle of glass tube, obtains the angular cut of differing tilt angles.
Compared with the prior art, the advantages of the present invention are as follows: the present invention is lower than cooling liquid using the density of conduction oil, makes
It obtains conduction oil to float on cooling liquid, while under the oil film action of conduction oil itself, so that in the upper surface of cooling liquid
The oil film of one layer of uniform ground is formed, and since conduction oil and cooling liquid are liquid conditions, is inserted into coolant liquid in glass tube
After body, the oil film of conduction oil is formed on the side wall of glass tube at cutting trace, and then is heated to conduction oil, in glass
It is located at the cutting trace contacted with oil film on glass pipe and forms high temperature, and is formed in the section that glass tube is contacted with cooling liquid low
Temperature, therefore concentrated stress is formd at the cutting trace of glass tube, under the effect of gravity, glass tube is in cutting trace for glass tube lower end
It is broken at mark, to realize the cutting of glass tube.Meanwhile in further embodiment, by changing inclining for glass tube
Rake angle can also obtain inclined notch.Therefore the present invention has the characteristics that easy to operate, while the present invention is cut in glass tube
A small amount of material and easy device are pertained only to during cutting, thus greatly reduces cutting cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of glass pipe cutting device in the embodiment of the present invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Such as Fig. 1, glass pipe cutting device in this implementation, including container 1, cooling liquid 2, conduction oil 3, heat-conducting metal 4,
Column 5, bracket 6, support plate 7 and collet.
Wherein, cooling liquid 2 and conduction oil 3 are placed in container 1, and conduction oil 3 floats on cooling 2 top of liquid, it is preferable that cold
But liquid 2 is water, and conduction oil 3 is edible oil, and column 5 is vertically arranged to the outside of container 1, bracket 6 be slideably positioned in column 5 it
On, support plate 7 is rotatably dispose on bracket 6, and scale is provided in support plate 7, is provided in support plate 7 for clamping glass
The collet of pipe 8.
Glass tube cutting method of the invention, comprising the following steps:
Step S1 pours into cooling liquid 2 in container 1；
Glass tube 8 to be cut is inserted into container 1 by step S2, and the upper surface of cooling liquid 2 is wrapped in glass tube 8
Side wall, cooling 2 upper surface of liquid and 8 side wall intersection of glass tube are formed at cutting trace；
Step S3 instills conduction oil 3 above cooling liquid 2 in container 1, stands a period of time, and the density of conduction oil 3 is small
In cooling liquid 2, conduction oil 3 uniformly diffuses to form one layer of oil film, the covering cutting trace of conduction oil 3 in cooling 2 upper surface of liquid
Place, wherein the time of standing is 1~3 minute；
The heat-conducting metal 4 of heating is inserted into the oil film of conduction oil 3 by step S4, and oil film is heated quickly, the heat of oil film
It being transferred at the cutting trace of glass tube 8, temperature of the glass tube 8 at cutting trace rises rapidly, meanwhile, in cooling liquid 2
Interior 8 lower temperature of glass tube is lower, and glass tube 8 generates concentrated stress, under the effect of expanding with heat and contract with cold, glass at cutting trace
Pipe 8 is broken at cutting trace.
Further, in step s 2, before cooling liquid 2 is inserted into 8 lower end of glass tube, in the lower end of glass tube 8
A pouring weight 9 is hung, by the way that pouring weight 9 is arranged, when generating concentrated stress at the cutting trace of glass tube 8, glass tube 8 is by pouring weight
9 one active forces pulled down, consequently facilitating glass tube 8 is broken at cutting trace.
Further, in step s 2, glass tube 8 is inserted into an inclined manner in cooling liquid 2, in this way, coolant liquid
The cutting trace that body 2 is formed is ellipse, and it is inclined for finally making the notch of glass tube 8.Specifically, in installation glass tube 8
When bracket 6 is moved up, bracket 6 is moved down after being installed, 8 lower end of glass tube and the contact of cooling 2 upper surface of liquid, rotation
Turn support plate 7, changes the tilt angle of glass tube 8, obtain the angular cut of differing tilt angles.
To sum up, the present invention is lower than cooling liquid 2 using the density of conduction oil 3 so that conduction oil 3 float on cooling liquid 2 it
On, while under the oil film action of conduction oil 3 itself, so that forming the oil of one layer of uniform ground in the upper surface of cooling liquid 2
Film, but since conduction oil 3 and cooling liquid 2 are liquid conditions, after glass tube 8 is inserted into cooling liquid 2, the oil of conduction oil 3
Film is formed on the side wall of glass tube 8 at cutting trace, and then is heated to conduction oil 3, be located on glass tube 8 with
High temperature is formed at the cutting trace of oil film contact, and forms low temperature in the section that glass tube 8 is contacted with cooling liquid, therefore in glass
Concentrated stress is formd at the cutting trace of pipe 8, under the effect of gravity, glass tube 8 occurs 8 lower end of glass tube at cutting trace
Fracture, so that the cutting of glass tube 8 is realized, in addition, when needing to obtain the glass tube 8 of angular cutouts, it only need to be by glass tube 8
Cooling liquid 2 is inserted by heeling condition.Therefore the present invention has the characteristics that easy to operate, while the present invention is cut in glass tube 8
A small amount of material and easy device are pertained only to during cutting, thus greatly reduces cutting cost.
