Description
Technical field
The present invention relates to metal-back dangerous material boring method.
Background technology
Inside is full of to the metal-back product of flammability hazard product, is the pressure changing of metal-back inside during the burning of test inflammable thing, needs to process through hole on housing.All adopt common bench drilling machine as drilling machine at present, use standard fluted drill, operated bore operation by manual site.When drill bit drills through housing wall, if can not feed-disabling at once, drill bit will charge into enclosure interior, the inflammable thing of its inside of drilling, drill bit is charged into enclosure interior and chip also can be caused to fall into inflammable thing, because cutting temperature is far above the burning-point of inflammable thing, drill bit is charged into housing or chip and is fallen into inflammable thing and all probably cause inflammable thing of igniting, and then explosion caused.Although also there is the safety measure adopting and install shoulder guard additional on drilling machine at present, owing to fundamentally not solving the problem that drill bit charges into enclosure interior, so cannot guarantee the safety of operating personnel, personal safety accident happens occasionally.The drilling safe of this series products has become problem demanding prompt solution in testing experiment.
Therefore, necessaryly a kind of metal-back dangerous material boring method is provided to solve above-mentioned technical problem.
Summary of the invention
Technical problem solved by the invention is to provide a kind of metal-back dangerous material boring method, and it can reduce blasts, even if meet accident blast, also can ensure the safety of operating personnel.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of metal-back dangerous material boring method, comprises the steps:
The first step: be in the fixture that is installed on boring main frame main shaft of the Thin board drilling bit of 180 ° by drift angle, metal-back dangerous material loaded in the fixture of boring main frame, and boring main frame is isolated be arranged in an explosion-proof cell;
Second step: operating personnel enter in a control room isolated with explosion-proof cell, and operate the control system in control room, this control system is connected with the boring main frame in described explosion-proof cell;
3rd step: while boring, detected in real time by described control system and record the axial force of drill bit;
4th step: according to the change of drill bit axial force, described control system judges whether metal-back is drilled through, when the axial force of drill bit sharply declines, described control system controls described drill bit and stops boring, and drill bit is retracted into zero-bit parking, completes drilling operating.
As the further improvement of the technical program, described control system comprises a controller, checkout gear and data storage device; Described checkout gear detects the axial force data of drill bit in the boring operational factor of main frame and boring procedure in real time, and is stored in described data storage device by the data detected; Described controller determines whether send to boring main frame the command signal stopping boring according to the drill bit shaft received to force data.
Compared with prior art, metal-back dangerous material boring method of the present invention, by the Real-Time Monitoring to drill bit axial force, whole boring procedure is controlled, when the axial force of holing is undergone mutation, stop the axial feed of drill bit and drill bit return zero-bit stopping, make boring more accurate, automaticity improves greatly, and in whole boring procedure, boring main frame and operating personnel are completely isolated, ensured the security of the personnel that hole.
Accompanying drawing explanation
Fig. 1 is the principle sketch of metal-back dangerous material boring method of the present invention.
Detailed description of the invention
Refer to shown in Fig. 1, the invention provides a kind of metal-back dangerous material boring method, its metal-back dangerous material hole-drilling system used comprises the boring main frame being positioned at antiknock indoor and the control system being positioned at control room.Described control system is connected with described boring main frame by connecting line, and controls the operation of this boring main frame.
Described boring main frame is isolated from the outside by antiknock room, and boring main frame is provided with a main shaft, is fixed on the drill bit on main shaft and is positioned on main shaft and clamps the fixture of described drill bit.The main shaft of described boring main frame rotates under the drive of motor, thus drives bit, makes drill bit and metal shell produce relative axial feed motion between the two, thus completes the drilling operating to metal shell.
In actual mechanical process, be divided into following steps:
The first step: be in the fixture that is installed on boring main frame main shaft of the Thin board drilling bit of 180 ° by drift angle, metal-back dangerous material loaded in the fixture of boring main frame; Employing drift angle is that the Thin board drilling bit of 180 ° can reduce the length that drill bit protrudes into metal shell,
Second step: operating personnel enter in the control room that isolates with main frame of holing, start drilling program;
3rd step: while starting boring, control system starts to detect in real time and records the axial force of drill bit;
4th step: according to the change of drill bit axial force, control system judges whether metal-back is drilled through, after drilling through, the axial force of drill bit sharply declines, now stops the axial feed of drill bit to run immediately, and drill bit is retracted into zero-bit parking, completes drilling operating;
5th step: operator enters antiknock indoor, takes out metal-back dangerous material, reinstalls next in fixture, and then holes from aforementioned second step, enter next circulation.
Described control system comprises a controller, checkout gear and data storage device.To hole described in described controller connection control main frame, described checkout gear is for detecting the axial force data of drill bit in the boring operational factor of main frame and boring procedure, and the data detected are stored in described data storage device, described controller judges duty and the bore state of boring main frame according to the data detected, and provide the command signal of adjustment, thus realize the control of antagonism shot room internal drilling main frame, such as, when detecting that the axial force of drill bit sharply declines, described control system stops the command signal of axial feed by sending, after boring main frame receives command signal, described drill bit will be retracted into zero-bit, complete boring procedure thus.
After having holed, operating personnel can enter antiknock indoor, take out metal-back dangerous material, and load metal-back dangerous material next hole to be drilled, thus carry out next round circulation.
In sum, metal-back dangerous material boring method of the present invention, when hole is drilled through, drill thrust can be undergone mutation (sharply declining), according to this jump signal, by the automatic feed-disabling of control system, substantially increase the security of boring procedure, and present invention employs isolating and protecting measure, drilling site and operating personnel are isolated, and can isolated operation be carried out, solve and drill through rear automatic stopping, drill bit protrudes into housing control etc., it can reduce blasts, even if meet accident blast, also can ensure the safety of operating personnel.
The above; it is only most preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; any those of ordinary skill in the art; do not departing under technical solution of the present invention ambit; utilize the method content of above-mentioned announcement to make many possible variations and modification to technical solution of the present invention, all belong to the scope of claims protection.
