Description
Technical field
The present invention relates to a kind of production method of detonator, concretely relates to a kind of high strength detonating tube production work
Skill.
Background technology
Current domestic high intensity production line pulling force generally exists（20-25）Between KG, mainly taken using three-layer co-extruded post-tensioning
To technology, but as the increase of stretching degree of orientation, molecules align regularity increase, longitudinal pulling force is caused to strengthen, lateral pull
Reduce.When lateral pull is too low, detonator is cracked during causing detonator propagation of explosion, venting of dust explosion occurs, phenomenon of miss-firing.
The equipment introduced from foreign countries mainly using outer layer technology during internal layer applies again is first drawn, make in applying again after interior formable layer,
Outer layer, using different materials different performance etc. to improve detonator intensity, and drawn according to each layer different proportion to adjust detonator
Power, but because material limits, pulling force upper limit expanded reach is limited.Meanwhile the detonator of the technique productions is general in use
It is larger all over stretcher strain, detonator fracture during use, detonator are easily caused because deforming abjection leads to not from detonator
Quick-fried detonator.
In addition, in the production process of existing detonator, dose is insufficient in the presence of one side or off-drug, stifled medicine or more occurs
The problem of medicine, cause directly to produce waste product or finished product in the too low phenomenon of actual use explosion velocity；On the other hand, due to cooling down, removing
Temperature control is improper during water so that and plastics shrink inconsistent in plasticizing process, cause that constancy is poor, caliber is uneven,
Phenomena such as so as to flat tube and elliptical tube occur.

4. high strength detonating tube production technology according to claim 1, it is characterised in that the primer Automatic Dosing system
System include medicine adding vehicle, drug storage cup, be arranged on primer it is temporary between and the lower medicine glass between and the rail that is run for the medicine adding vehicle
Road, the sensor being arranged on the lower medicine glass and control system.
5. high strength detonating tube production technology according to claim 4, it is characterised in that medicine glass dose sensor sense instantly
When should arrive lower medicine glass dose and reaching lower limit, signal is sent to control system, after control system receives signal, control medicine adding vehicle is along rail
Road is run, and the primer positioned at primer between temporary is transported under cross-head through medicine adding vehicle and the positioning of drug storage cup
Medicine glass, through 180 ° of rotation drug storage cups, primer is poured under extruder in medicine glass, realizes Automatic Dosing.
6. high strength detonating tube production technology according to claim 1, it is characterised in that four de-watering apparatus structure phases
Together, including along detonator lead the electromagnetic shaker that sets, support and it is arranged on support and is used to place the water removal of dehydrating material
Material rack and blow device.
7. high strength detonating tube production technology according to claim 6, it is characterised in that when being removed water, adopt first
The detonator come out from cooling pond is shaken with electromagnetic shaker, makes to be attached to effect of the globule on detonator in exciting force
Under come off, and the detonator to being come out from cooling device carries out further air cooling；Detonator is set to be placed through water removal material again
Frame is in contact with water removal material, the residual water droplet on erasing detonator surface；Finally utilize through dry, 0 ~ 25 DEG C of compressed air pair
Detonator after vibration is dehydrated is purged, and detonator is cooled down again.
8. high strength detonating tube production technology according to claim 1, it is characterised in that step（6）In, using dose and
Caliber laser detector is detected, compared with the detonator dose and diameter value that set whether off-drug or overproof, if going out
Existing off-drug or diameter are overproof, then dose and apparatus for detecting diameter alarm；When diameter is overproof, finely tune extruder extruded velocity or
Haulage gear hauling speed, detonator diameter is set to enter in standard value.
