Abstract
The utility model discloses a boring device which comprises a tool bit fixing fixture, tool bits arranged on the tool bit fixing fixture and a gripping head connected with the tool bit fixing fixture. Studies show that the mica insulation material is high-temperature resistant but softer, so the boring device can be used to break the mica insulation layer at the periphery of a heating copper rod to enable the whole heating copper rod to drop off. When in use, the boring device is used in combination with an electric drill, the gripping head is clamped on the electric drill, and the tool bits rotate under the drive of the electric drill to drill the mica insulation layer at the periphery of the heating copper rod so as to enable the whole heating copper rod to drop off eventually. Due to the adoption of the boring device, the time for replacing the heating copper rod is greatly shortened, labor and time are saved, and the uptime rate of oil press equipment is improved.

Technical field
The application relates to the machining equipment technical field, particularly relates to a kind of hole making drill.
Background technology
In the extrusion process of production of hydraulic press, utilize special-purpose heater that the extruding ingot casting is heated, so that the temperature of described ingot casting is in certain temperature range, described heater is specially the series connection of many heating copper rods and constitutes, make the copper rod heating for described heating copper rod feeds low-voltage and high-current, need temperature thereby the heating recipient reaches production.But, owing to big electric current passes through the heating copper rod for a long time, the electricity that causes heating copper rod is ablated seriously, and then causes that heating copper rod net sectional area reduces, in the course of time indivedual copper rods cause indivedual heating copper rods to be blown just because of sectional area reduces to cause the conductive capability variation under the big function of current.Again because of electric ablation stratum disjunction around the long-term energising copper rod forms relatively closely firm packed layer with the mica material that insulate around the copper rod, the copper rod that wants to take off damage in this case is very difficult.
Take off the traditional method that damages copper rod and be and utilize diameter to make the target drill of a plurality of different lengths for the 30mm drill bit, the copper rod that blows is carried out drilling cuttings, this method efficient that wastes time and energy is extremely low, has a strong impact on the rate of starting of hydraulic press.
The utility model content
For solving the problems of the technologies described above, the embodiment of the present application provides a kind of hole making drill, and to improve the speed of changing the heating copper rod on the hydraulic press, technical scheme is as follows:
A kind of hole making drill comprises: the cutter head stationary fixture;
Be arranged on a plurality of cutter heads on the described cutter head stationary fixture;
Be arranged on the described cutter head stationary fixture chuck away from described cutter head.
Preferably, described cutter head stationary fixture is a seamless steel pipe, and this seamless steel pipe one end evenly is provided with a plurality of openings that are used for fixing described cutter head.
Preferably, described a plurality of cutter heads evenly are arranged on the opening of described cutter head stationary fixture, and have predeterminable range between the center line of adjacent tool tips center line and its corresponding opening.
Preferably, the diameter of the end that described chuck is connected with described cutter head stationary fixture and this cutter head stationary fixture diameter are complementary, and other end diameter is 13mm, and the central lines of the center line of this chuck and described cutter head stationary fixture.
Preferably, described chuck is welded on the described cutter head stationary fixture.
Preferably, the number of described cutter head is 6.
Preferably, described cutter head is a carbide bit.
Preferably, described cutter head is welded on the described cutter head stationary fixture.
The technical scheme that is provided by above the embodiment of the present application as seen, described hole making drill comprises the cutter head stationary fixture, is arranged on the cutter head on this cutter head stationary fixture, and the chuck that is connected with described cutter head stationary fixture, the inventor finds after deliberation, though mica insulator is high temperature resistant, material is softer, therefore, utilize this hole making drill to destroy heating copper rod mica insulation layer on every side, thereby whole heating copper rod come off.During concrete the use, the supporting use of this hole making drill and electric drill, described chuck is clamped on the electric drill, cutter head rotates under the drive of electric drill, thereby the insulation mica layer around the heating copper rod is rotated drilling cuttings finally makes whole heating copper rod come off, use this hole making drill can shorten the time of changing copper rod greatly, save manpower and time, improved the rate of starting of hydraulic press equipment.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, the accompanying drawing that describes below only is some embodiment that put down in writing among the application, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of facing of a kind of hole making drill of the embodiment of the present application;
Fig. 2 is the side-looking structural representation of a kind of hole making drill of the embodiment of the present application.
The specific embodiment
In order to make those skilled in the art person understand technical scheme among the application better, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
Referring to Fig. 1 and Fig. 2, Fig. 1 provides a kind of structural representation of facing of hole making drill for the embodiment of the present application, and Fig. 2 provides a kind of side-looking structural representation of hole making drill for the embodiment of the present application, and this hole making drill mainly comprises: cutter head stationary fixture 1, cutter head 2, chuck 3.
One end of described cutter head stationary fixture 1 evenly is provided with a plurality of cutter heads 2, and the other end is provided with chuck 3.
Preferably, described cutter head stationary fixture 1 can be a seamless steel pipe, and the end on the described seamless steel pipe is provided with equally distributed a plurality of opening.Cutter head 2 can be selected carbide bit for use, a plurality of cutter heads misplace respectively and are fixed on described opening part, it is the adjacent tool tips default distance that on the center line of described opening part, staggers, so that the rotary cutting diameter is greater than the diameter of described cutter head stationary fixture 1, thus the rotational resistance when reducing rotary cutting.During concrete enforcement, cutter head 2 can be welded on the opening part of cutter head stationary fixture.
The quantity of described cutter head stationary fixture 1 upper shed and cutter head 2 is 6, and described 6 openings are symmetrically distributed on the circumference of cutter head stationary fixture.Can certainly be other more than two quantity, the application limit this.
