Description
Technical field
The utility model relates to cable technical field, specially a kind of production line of mineral insulated cable.
Background technique
Mineral insulated cable be one kind using metallic copper as sheath, using inorganic mineral (usually magnesia powder) as
The mineral cable of insulating layer.Because being free of organic material in the composition of mineral insulated cable, the fusing point of sheath copper is in structure
1083 DEG C, the fusing point of magnesia powder is 2800 DEG C or so, thus this kind of cable can the fusing point close to copper at a temperature of continue
Normal power-up has excellent refractory ability.It is widely used in fire-fighting electrical power transmission system and place resistant to high temperature, such as
Skyscraper, megastore, petrochemical industry, airport etc..The fireproof cable that China uses at present domesticizes completely, still
Production equipment and mode are had nothing in common with each other.Exist in the prior art it is a kind of copper strips is curled into tubulose after, connect with argon arc welding welding
The production technology and relevant device of mouth.The advantages of this mode is the mineral insulated cable that can produce random length,
Intermediate connector is added between avoiding in the cable.But cable made from this mode is there are soldered, continuous drawing at
During product, it is easy to produce crackle, the insulating layer moisture absorption is caused to fail.Therefore, security reliability ratio is made not in this way
Upper seamless mineral insulated cable.Also have at present and obtains the production work of mineral insulated cable using seamless steel pipe continuous drawing
Skill, but the cable length produced is very short, some only has tens meters, is unable to satisfy the demand of most engineering designs.
Utility model content
The purpose of this utility model is to provide a kind of production lines of mineral insulated cable, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions: a kind of production of mineral insulated cable
Line, including the first vertical pulling machine, the second vertical pulling machine and plate drawing machine, the outlet roller-way of the first vertical pulling machine and the second vertical pulling machine outlet
Roller-way is arranged in parallel in the inlet side roller-way two sides of roller bottom furnace respectively, and the outlet roller-way side of roller bottom furnace is equipped with plate drawing machine.
The first vertical pulling machine and the second vertical pulling machine are respectively connected with shrinking machine.
The first vertical pulling machine is 30m vertical pulling machine, and the second vertical pulling machine is 70m vertical pulling machine.
As shown from the above technical solution, the utility model is by being respectively adopted two different vertical pulling machines to cable drawing,
It is applicable to the semi-finished product cable of different radii and pulling capacity, while the assembly method of cable makes technology stability more preferable, at
Product qualification rate is high, compared with previous single bracing wire production line, can effectively reduce equipment loss, improve productivity.
Detailed description of the invention
Fig. 1 is the utility model production line schematic diagram.
In figure: 1 shrinking machine, 2 first vertical pulling machines, 21 vertical pulling machine roller-ways, 3 second vertical pulling machines, 31 3 line machine drawing inlet side rollers
Road, 32 3 line machine drawing outlet roller-ways, 4 roller bottom furnaces, 41 roller bottom furnace inlet side roller-ways, 42 roller bottom furnace outlet roller-ways, 5 plate drawing machines, 51 weeks
Turn wire body roller-way, 6 shaft furnaces.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
A kind of production line of mineral insulated cable, including the first vertical pulling machine and the second vertical pulling machine, first vertical pulling
Machine and the second vertical pulling machine are respectively connected with shrinking machine, and the first vertical pulling machine is 30m vertical pulling machine, and the second vertical pulling machine is that 70m is straight
Machine drawing, the outlet roller-way of the first vertical pulling machine and the second vertical pulling machine outlet roller-way are arranged in parallel in the inlet side roller of roller bottom furnace respectively
The outlet roller-way side of road two sides, roller bottom furnace is equipped with plate drawing machine.
As shown in Figure 1, step 1, chooses the copper pipe, copper rod and porcelain knob for being applicable in specification, and use wine first in assembling process
Copper pipe and copper rod are wiped and are dried for use by essence, while porcelain knob being put into 150 DEG C of ovens and is toasted 2 hours, by porcelain knob after baking
Be fitted into copper pipe, and by copper rod insertion porcelain knob inner hole in, after the assembly is completed select wire-drawing die by clamping end with shrinking machine 1 into
Row tube reducing processing, to facilitate the first vertical pulling machine 2 to clamp；Step 2 gets out wire-drawing die, and gradually on the first vertical pulling machine 1
Drawing, the first vertical pulling machine 1 preferred 30m vertical pulling machine will be transmitted to roller bottom furnace inlet side through vertical pulling machine track 21 after the completion of drawing
On roller-way 41, and the parameter for setting roller bottom furnace 4 starts to anneal；Step 3, when cable length is more than the length of 30m vertical pulling machine
Afterwards, cable is transferred to the second vertical pulling machine 3 by three line machine drawing inlet side roller-ways 31 and carries out drawing, the preferred 70m of the second vertical pulling machine
Vertical pulling machine, the cable after drawing is transmitted on roller bottom furnace inlet side roller-way 41 by three line machine drawing outlet roller-ways 32, and sets roller
The parameter of bottom furnace 4 starts to anneal, and continues to carry out drawing next time on 70m vertical pulling machine after the completion of annealing, until meeting setting ruler
It is very little be transferred to disk draw until；Step 4 gets out wire-drawing die and is mounted on plate drawing machine 5, and by cable through roller bottom furnace outlet roller
Road 42 is transmitted on turnover wire body roller-way 51, is finally drawn, the cable after the completion of drawing is placed on machine frame, the passage by root disk
After the completion of drawing, cable being put into Jing Shi furnace 6 and is annealed, after the completion of annealing, continuation carries out drawing next time on plate drawing machine 5,
Continue to anneal after the completion of drawing, until cable is drawn to finished product outer diameter requirement.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
