Abstract
The utility model relates to an intermediate frequency heat treatment equipment for drill collar and drill rod type oil drill tools, which comprises at least inductor group which is composed of three segments of concentric inductors, a conveyance device of workpiece to be treated, and an AC contactors to connected with all inductors. Two connection methods are used between inductors and AC contactor, the first method is that firstly prior several inductors are connected in parallel connection and then other later inductors are connected in series. The second method is that all inductors are connected in series. In the first method, as parallel connection is adopted, impedance is reduced and power is increased, so it is suitable for heating when quenching, in the second method, impedance is large and power is low, so it is suitable for heating when tempering, the utility model adopts a group of inductors to meet the requirement of tempering and quenching for different power. Moreover the utility model has the advantages of simple structure and convenient adjustment.
Description
Technical field
The utility model belongs to the Equipment for Heating Processing of stock class workpiece, the modified Equipment for Heating Processing of intermediate frequency of specifically a kind of drill collar, extra-weight drillpipe class oil drilling tools.
Background technology
The drill collar in the oil drilling tools and the thermal treatment of extra-weight drillpipe are except that adopting conventional resistance furnace heating, also
Have and adopt line-frequency induction to heat, and the frequency fixing of line-frequency induction heating can't be regulated, so be difficult to satisfy simultaneously of the different requirements of different size workpiece Heating temperature or depth of penetration heating.Drill collar and extra-weight drillpipe belong to stock class workpiece, existing stock class workpiece carries out induction quenching and two cover induction heaters are often adopted in the tempered modifier treatment, promptly, the heating of quenching of an induction heater, another carries out the tempering heating, just adopted two induction heaters to quench respectively and tempering as the disclosed sucker rod medium frequency induction hardening of Chinese patent CN2556208 tempering unit, this makes use of momentum and must want two cover intermediate frequency power supplies, not only increase the investment of equipment, and caused the complexity of structure.
The induction heating of stock class workpiece adopts the heating of more piece inductor block mostly, and existing heating unit with more piece inductor block is that one inductor block is simply come on the line basically, and each inductor block all has the installation frame of oneself, is separated from each other.So when changing the specifications vary of inductor block or heated parts, it is consuming time not only to consume the worker, and the adjustment difficulty of the height of center of inductor block and concentricity is bigger.
Summary of the invention
Problem to be solved in the utility model is to overcome above-mentioned existing in prior technology deficiency, provide a kind of easy to adjust, and adopt one group of inductor block just can satisfy simultaneously to quench in modified and tempering adds the drill collar of heat request, the modified Equipment for Heating Processing of intermediate frequency of extra-weight drillpipe class oil drilling tools.
The technical scheme that addresses the above problem is: the modified Equipment for Heating Processing of intermediate frequency of the drill collar that is provided, extra-weight drillpipe class oil drilling tools has at least the inductor block group be made up of the inductor blocks of three joint concentric arrangement and the e Foerderanlage of processed workpiece, special feature of the present utility model is: be provided with the alternating current contactor group that is connected with each inductor block, each inductor block and alternating current contactor group have two kinds of connection state, are connected in series with remaining inductor block of back after several inductor blocks that first kind of connection state is the front are connected in parallel again; Second kind of connection state is that whole inductor blocks are connected in series.Because the part inductor block has adopted parallel connection, and impedance reduces, power increases in first kind of connection state, so the heating when being used to quench; The impedance of second kind of connection state is big, and power is lower, so the heating when being used for tempering.
Quench and the tempering two states in order further to adapt to, each inductor block can also adopt the structure that becomes pitch of turn, that is: the coil turn of the inductor block that is connected in parallel when first kind of connection state is apart from the coil turn distance less than all the other inductor blocks.
Generally speaking, above-mentioned inductor block can be three or six, can certainly be four or five, but is preferably three or six.
When above-mentioned inductor block is three, after being connected in parallel, two inductor blocks that first kind of connection state is the front are connected in series with an inductor block of back again.
When above-mentioned inductor block is six, after being connected in parallel, four inductor blocks that first kind of connection state is the front are connected in series with two inductor blocks of back again.
In order to adapt to the variation of specification of workpieces, above-mentioned each inductor block preferably is installed on the support, and this support is inserted on former and later two gantry frames, is provided with the hoisting appliance of support between this support and the gantry frame.So not only can change inductor block easily, and just can adjust the height of center of inductor block by hoisting appliance easily.
In order to guarantee workpiece uniform motion vertically, guarantee the even heating of workpiece, the e Foerderanlage of above-mentioned processed workpiece can be the rollgang when comprising the heating of being made up of a plurality of V-arrangement rotation rollers, a V-arrangement rotation roller is set at least, the axis and the throughput direction oblique of rotation roller between wherein per two inductor blocks.
Compared with prior art, the utility model changes heating power by the annexation that changes each inductor block, and is not only simple in structure, and maintenance, easy to adjust; Add heat request owing to adopt one group of inductor block just can satisfy modified middle quenching simultaneously with tempering, so greatly reduce production cost and energy consumption.
