Abstract
The utility model discloses a protection device capable of preventing induction soft belt during quenching of a camshaft and aims at providing the protection device which is stable in quality and can effectively prevent the induction soft belt. The protection device comprises a protection water sleeve which is arranged below a quenching inductor, the protection water sleeve is connected with a cooling water tank through a water pipe and a water pump; and the cooling water tank is communicated with a cooling medium pond through a water inlet pipe. When the protection device is used, a power line of the water pump is connected with a heating system in an electric appliance control cabinet in the quenching process. When the camshaft ascends to a preset position, the heating instruction of the inductor is started to heat a cam in an induction way, the water pump is started simultaneously, the medium water is sprayed out through the protection water sleeve from a water spray hole, and the temperature of the quenched cam below is prevented from rising; and when a heating procedure stops, the protection water sleeve simultaneously stops spraying water. At the moment, a cooling instruction of the inductor is started, and the heated cam is cooled and quenched, so that the induction soft belt of the cam at the lower part can be avoided while the cam is heated.
Description
Technical field
The utility model relates to the protector in a kind of camshaft machining process, relates in particular to when the camshaft induction quenching, prevents the protector of the soft band of induction.
Background technology
Soft band is a kind of defect mode common in the induction quenching; Camshaft induction quenching order generally is to carry out one by one successively from top to bottom; If the gap between two cams too hour; Quenched below causing easily during to the top one grade of cam heating edge of cam receives Influence of Temperature and makes its decrease of hardness, promptly forms the soft band of induction.
The mode that soft band is responded in traditional prevention mainly is that the adjacent position of having quenched of device preventing through increasing magnetic field shielding is by induction heating.If but two quenching cam positions be separated by when very near, it is very limited that the mode effect of soft band is responded in this prevention, is difficult to guarantee quality of stability.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve provides the protector of the soft band of a kind of camshaft quenching prevention induction, and its steady quality can effectively prevent to respond to the generation of soft band.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of camshaft quenches and prevents the protector of the soft band of induction; Comprise the protection water jacket of being located at the quenching inducer below, said protection water jacket is connected with a cooling water tank with water pump through water pipe.
Further, said cooling water tank is connected with a heat-eliminating medium pond through a water inlet pipe.
Further, said cooling water tank upper side wall is provided with posticum.
Further, said water inlet pipe is provided with valve.
Further, said posticum is connected with the heat-eliminating medium pond through water pipe.
In the time of use, the heating system in the electric control cabinet in the supply lead of above-mentioned water pump and the quenching process is connected.When camshaft rises to the predetermined position; Inductor block heating instruction starts carries out induction heating to cam; Starting mode of pump in the while water tank, WATER AS FLOW MEDIUM, raises with the cam temperature of quenching below preventing by the oblique ejection down of spiracle through the protection water jacket; When heating schedule stopped, the protection water jacket stopped water spray simultaneously.This moment, inductor block cooling instruction started, and the heating cam is sprayed cold quenching, and cam is responded to the formation of soft band below so just when the heating cam, effectively preventing.
Compared with prior art, the utlity model has following beneficial effect: this protector can with the heating of inductor block instruction effect simultaneously, cooling performance is obvious, steady quality is reliable, and heat-eliminating medium is convenient to recycle, and is very convenient and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, protection water jacket, 2, water tank, 3, water pump, 4, water inlet pipe, 5, posticum, 6, valve, 7, inductor block.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
Referring to Fig. 1; A kind of camshaft quenches and prevents the protector of the soft band of induction, comprises protection water jacket 1, and this protection water jacket 1 is waited in use through bolt and is connected quenching inducer 7 belows; Said protection water jacket 1 is connected with a cooling water tank 2 with water pump 3 through water pipe; Said cooling water tank 2 also is connected with a heat-eliminating medium pond through a water inlet pipe 4, and said water inlet pipe 4 is provided with valve 6, guarantees the supply of heat-eliminating medium; Said cooling water tank 2 upper side walls are provided with posticum 5, posticum 5 usefulness cross current to the heat-eliminating medium pond, unnecessary like this heat-eliminating medium can be back to the heat-eliminating medium pond.
In the time of use, the heating system in the electric control cabinet in the supply lead of water pump 3 and the quenching process is connected.
