The conductive heating drilling device has the advantages that the first electrode and the second electrode are arranged in the longitudinal direction, a workpiece is clamped between the first electrode and the second electrode, conductivity is guaranteed, no electricity currents pass through a tool, and accordingly an electric arc phenomenon caused when a twist dill is used for drilling is avoided; drilling force is reduced by 1/3-1/2 than that of common drilling, drilling efficiency is improved, stability is high, quality of small holes obtained through drilling is good, and the drilling device has good market prospects.
Description
Technical field
The utility model relates to drill unit field, is specially a kind of conductive heater drill unit.
Background technology
High strength steel is due to the increasingly extensive application in special component of its incomparable superperformance.But if the high strength steels such as manganese steel are owing to having very high intensity, in the time of boring and machining, run into extremely formidable difficulty.Existing drill unit is in the time of the above-mentioned high strength steel of processing, and operating efficiency is extremely low, and drilling life of bit is very short, and processing cost is high; In otch or boring, also can exist in addition tear, the manufacturing deficiency such as burr, had a strong impact on the borehole accuracy of high strength steel, further restricted production efficiency and the crudy of high strength steel member.
Utility model content
The purpose of this utility model is the deficiency existing for the above prior art, provides a kind of simple in structure, and drilling efficiency is high, the conductive heater drill unit that drilling quality stability is high.
The utility model is achieved in that a kind of conductive heater drill unit, comprise workbench, drill bit, be installed on the first electrode and the second electrode on described workbench, between described the first electrode and the second electrode, it is workpiece installing space, described the first electrode is connected with power supply respectively with the second electrode, and described drill bit is installed on described the first electrode top.
Described the first electrode and the second electrode are copper material, to ensure electric conductivity.
Described the first electrode is that diameter is 1-3mm contact piece, and it is 1.8-2mm bullport that diameter is set in described contact piece.
Compared with prior art, the advantage the utlity model has is: adopt the first electrode setting up and down and the second electrode structure, workpiece clamp is between upper/lower electrode, for ensureing electric conductivity, material all adopts brass, and electric current, without cutter, produces arc phenomenon while avoiding like this fluted drill to pull out of hole; Drill thrust can realize than common drilling time reduces 1/3～1/2; Improved drilling efficiency, stability is high, and the aperture quality that drilling obtains is good, has good market prospects.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of conductive heater drill unit of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of conductive heater drill unit of the utility model is described in detail.
A kind of conductive heater drill unit, as shown in Figure 1, comprising workbench 5, drill bit 1, be installed on the first electrode 2 and the second electrode 4 on described workbench 5, is workpiece 6 installing spaces between described the first electrode 2 and the second electrode 4, and described the first electrode 2 is connected with power supply respectively with the second electrode 4.Described drill bit 1 is installed on described the first electrode 2 tops, conducts drilling for realizing.Wherein, described power supply can be inverter, the boundling effect of the electric current that can strengthen.Described drill bit 1 is carbide alloy (YG6A) fluted drill.And described the first electrode 2 and the second electrode 4 are copper material, to ensure electric conductivity.Between described workbench 5 and workpiece 6, felt pad 7 is set, at described workpiece 6 upper surfaces, described dynamometer 3 is set, described dynamometer 3 is connected with data collecting card by amplifier, and described data collecting card is connected with computer, for monitoring cutting pressure.Described the first electrode 2 and the second electrode 4 are installed in corresponding electrode tip holder.Described workpiece can corrosion resistant plate or the difficult to machine material such as potassium steel or normalizing 45# steel plate.Described the first electrode 2 is for diameter is 1-3mm contact piece, and it is 1.8-2mm bullport that diameter is set in described contact piece.
The utility model adopts described the first electrode 2 and the second electrode 4 structure setting up and down, electric current is without cutter, while avoiding like this fluted drill to pull out of hole, produce arc phenomenon, workpiece clamp is between described the first electrode 2 and the second electrode 4, the material of described the first electrode 2 and the second electrode 4 all adopts brass, ensures electric conductivity.
The utility model electric hot machining technology is a kind of typical complex machining process, it is in working angles, to utilize cutter and workpiece to form loop, pass to low-voltage, high-current, by the fuel factor of electric current make cutting region material be heated produce Joule heat soften, the essence of metal softening effect is that the rising of cutting temperature reduces metal hardness or Yield Strength of Metals reduces the variation that causes flow stress, and flow stress reduces along with the rising of temperature.Reduce the shearing drag of material, cutting is become smoothly, can obtain the surface roughness that is equivalent to grinding, and machined surface is without sclerosis or ruckbildung.The maximum feature of this method is: heating directly occurs in cutting deformation district, and the thermal efficiency is high, and energy consumption is little, heats up rapidly, little to workpiece material heat effect, compact conformation simultaneously, and temperature control is simple, is suitable for various cutting process.
Above-described embodiment is not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
