The utility model relates to a high-frequency quenching mechanism of a helical hobbing cutter of a mower. The high-frequency quenching mechanism comprises a quenching machine tool, wherein a central frame which can move up and down is arranged on the quenching machine tool; a guide wheel shaft is fixed between an upper thimble and a lower thimble of the central frame; the hobbing cutter is sleeved on the guide wheel shaft; an inductor is coupled on a hobbing cutter mouth of the hobbing cutter; a magnetizer is embedded on the outer diameter of the inductor; a water spraying ring is arranged below the inductor; a nozzle of the water spraying ring is arranged opposite to a cutting head; a guide wheel is fixed on the quenching machine tool; and the guide wheel is coupled with a blade of the hobbing cutter. The high-frequency quenching mechanism disclosed by the utility model has the beneficial effects that: a high-frequency vortex skin effect is good; concentrated cooling can be carried out, so that the hardness of high-frequency quenching of the hobbing cutter is uniform; and quality and stability of the hobbing cutter are improved.
Description
Technical field
The utility model relates to a kind of mower spiral hobbing cutter high-frequency quenching mechanism.
Background technology
The mower hobboing cutter is made up of knife rest and blade, and global shape is a cylinder type, and blade is welded on the cylinder shaped as frame knife rest, and blade shapes must be " S " type, and blade material is an alloy spring steel, and thickness has only 3mm, and the integral quenching distortion is difficult to control, and toughness is relatively poor.Therefore, must adopt integral solder moulding hobboing cutter, the edge of a knife adopts high-frequency induction quenching, just can reach request for utilization.
High-frequency quenching starts high-frequency current and can heat cooling normally with inductor block and hobboing cutter coupling, reaches the quenching purpose.Because the limitation of blade thickness, and knife rest is the empty frame of shaped as frame, and frequency eddy current surface action is difficult to form, and can not reach induction heating, and conventional inductor block spiracle disperses, and can not concentrate cooling, so can't reach induction hardened effect.
Summary of the invention
The purpose of the utility model is to provide the mower spiral hobbing cutter high-frequency quenching mechanism that a kind of quenching effect is good, improved hobboing cutter quality and stability.
The utility model is realized through following technical scheme:
Mower spiral hobbing cutter high-frequency quenching mechanism comprises quenching machine, and steady rest moving up and down is installed on the said quenching machine; Said steady rest be fixed with guide wheel shaft up and down between the thimble; Be set with hobboing cutter on the said guide wheel shaft, it is characterized in that: be coupled with inductor block on the hobboing cutter mouth of said hobboing cutter, be inlaid with magnetizer on the external diameter of said inductor block; The below of said inductor block is equipped with water spray ring, and the nozzle subtend cutter head of said water spray ring is provided with; Be fixed with guide deflection sheave on the said quenching machine, the blade coupling of said guide deflection sheave and hobboing cutter.
Further, said inductor block is the inductor block of two circle tandem types, and it comprises last circle that is used for preheating and the following circle that is used to heat.
Further, said magnetizer is arranged on the external diameter of inductor block apart from size by branches such as hobboing cutter blades.
When the utility model uses, earlier hobboing cutter is installed on the steady rest of high-frequency quenching machine, fixes with thimble up and down; Guide deflection sheave is fixed on the lathe bed; Guide deflection sheave withstands hobboing cutter " S " type blade, and follow rest moves up and down, thereby hobboing cutter is slowly rotated with the guiding crop rotation; Move down hobboing cutter again after normal, inductor block is installed; For strengthening surface action, inlay magnetizer at branches such as inductor block external diameter one side and hobboing cutter blades apart from size, with the enhance induction effect; When the unlatching quenching machine moved up and down, the hobboing cutter mouth of hobboing cutter and the magnetizer position of inductor block remained couple state at this moment; Water spray ring also will be installed with inductor block synchronously, and nozzle subtend cutter head makes it concentrate the water spray cooling; Can open high frequency electric source after the installation, ordering parameter can carry out hardening step, makes its hobboing cutter high-frequency quenching even hardness, and depth of hardening zone meets technical requirements fully.
The beneficial effect of the utility model: high frequency frequency eddy current surface action is good, can concentrate cooling, makes the even hardness of hobboing cutter high-frequency quenching, has improved the quality and the stability of hobboing cutter.
