Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of suspension type workpiece air cooling equipment, this suspension type workpiece air cooling equipment is applicable to being combined into continuous print production line with miscellaneous equipment, and effectively can improve speed of cooling and the cooling uniformity energy of workpiece.
The technical scheme realizing above-mentioned purpose is: a kind of suspension type workpiece air cooling equipment, and comprise blowing blower fan and a cooling room, the front and back of this cooling room arranges workpiece inlet/outlet respectively; In described cooling room, blow box is arranged in pairs in left and right, and the inner side of each blow box connects the duct set that is distributed with spray orifice respectively; Described blowing blower fan assembling blowing pipeline, the air outlet of this blowing pipeline is connected with the lower end of described blow box; The top assembling air inducing case of described cooling room, the air outlet of this air inducing case connects induced pipe, the air outlet assembling air inducing blower fan of this induced pipe.
Further, described left and right blow box arranged in pairs is arranged before and after multipair in described cooling room.
Further, described blowing blower fan arranges multiple stage, and the blowing pipeline respectively described in assembling, the air outlet of each blowing pipeline connects with the lower end of corresponding blow box respectively.
The blowing blower fan of the present invention by assembling and the strong cyclic of air inducing blower fan formation cooling air, effectively can improve the speed of cooling of workpiece.
The present invention utilize the spray orifice on duct set make cooling air evenly at a high speed be injected on workpiece, make each point on workpiece fast, evenly, continuous print cooling.Infrared thermometer can be utilized to carry out multiple spot monitoring to the temperature of workpiece in the process of cooling, carry out the adjustment of whole air cooling system speed of cooling simultaneously by fan frequency conversion or electric air volume adjusting valve, make workpiece within the time of process stipulation, be cooled to the temperature set uniformly.
The present invention realizes subregion and cools by being arranged in coordinating of the blowing blower fan of the blow box in cooling room and assembling and control, not only can prevent from producing between them because disturbing the pressure drop and pressure inequality that cause, Discrete control can also be realized to the cooling of workpiece, make quality product and cost control obtain two-way lifting.
The present invention drives load beam, clincher boarding, suspender and the workpiece be suspended on below suspender to enter cooling room by the Stacking Type Hang Conveyer being arranged on cooling room top, drives entirety to leave cooling room after having cooled by transfer roller.Clincher boarding coordinates with gap, the top place of cooling room and makes, and realizes sealing.The present invention is connected into a production line by other device such as Stacking Type Hang Conveyer and process furnace, can continuous seepage, is conducive to enhancing productivity, quality product and output.

Embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described.
As accompanying drawing, this suspension type workpiece air cooling equipment comprises a cooling room 1, and this cooling room 1, in perpendicular rectangular box shape of putting, forms with high-quality shaped steel and Plate Welding.The front and back of cooling room 1 arranges workpiece and imports and exports and assemble workpiece inlet/outlet 9 respectively, and each workpiece inlet/outlet 9 assembles pneumatic or fluid pressure drive device respectively, realizes the opening and closing of workpiece inlet/outlet.Perpendicular the putting of the long strip shape blow box 2 of upper end closed is installed on cooling room 1 inside, and left and right is arranged in pairs, and as accompanying drawing embodiment, left and right blow box arranged in pairs 2 is arranged before and after multipair in cooling room 1.Duct set 8 is fixedly connected with being communicated with in blow box in the relative inner of each blow box 2.Duct set 8 adopts the round tube of closed at both ends, as Fig. 3, Fig. 4, circular air-out spray orifice is distributed with before duct set 8, duct set 8 and blow box 2 joint face are arranged and the rectangular opening be communicated with in blow box 2, this rectangular opening arrangement is conducive to the rigidity improving duct set 8, is also conducive to uniform air intake simultaneously.The height of each duct set 8 is slightly larger than the length of maximum workpiece.Blowing blower fan 4 adopts centrifugal blower, and blowing blower fan 4 assembles blowing pipeline 3, and the air outlet of this blowing pipeline 3 is divided into left and right two-way and the lower end of the blow box 2 arranged with left and right is respectively connected.As accompanying drawing embodiment, blowing blower fan 4 is applicable to arranging multiple stage, and assembles blowing pipeline 3 respectively, and the air outlet of each blowing pipeline 3 is communicated with the lower end of relative multiple blow boxs 2 respectively and connects, and is formed by the work-piece cools district of different blowing blower fan 4 air feeds.Every platform blowing blower fan 4 controls air feed separately, not only can prevent from producing between them because disturbing the pressure drop and pressure inequality that cause, can also realize Discrete control, make quality product and cost control obtain two-way lifting to the cooling of workpiece.The top assembling air inducing case 7 of cooling room 1, the blast inlet of this air inducing case 7 lower end is communicated with workpiece accommodating cavity, and the upper end air outlet of air inducing case 7 connects induced pipe 5, the air outlet assembling air inducing blower fan 6 of induced pipe 5.
The air quantity of the air inducing blower fan of this suspension type workpiece air cooling equipment is greater than the total blast volume of blowing blower fan, and the hot blast after exchange is discharged completely, improves work-piece cools efficiency.
After the assembling of this suspension type workpiece air cooling equipment, workpiece is driven by Stacking Type Hang Conveyer and enters in cooling room 1, and is stuck between two relative duct sets 8; When multipair duct set works simultaneously, the workpiece that each duct set 8 is just stopping one, after the cooling air provided by blowing blower fan 4 enters blow box 2 by blowing pipeline 3, enter duct set 8 by the blast inlet after duct set 8 all to press, the air outlet opening distributed above by duct set 8 more directly blows to workpiece at a high speed, makes workpiece carry out cooling fast, uniformly.Hot blast after carrying out heat exchange with workpiece is discharged into specified location by air inducing case 7, induced pipe 5, air inducing blower fan 6.
This suspension type workpiece air cooling equipment is specially adapted to the air-cooled technique of workpiece after the especially axle rod workpieces normalizing of medium-and-large-sized suspension type workpiece, tempering heat treated.This suspension type workpiece air cooling equipment can centering large suspension-type workpiece especially axle rod workpieces carry out fast, evenly, the air-cooled process of continuous print, make workpiece within the time of process stipulation, be cooled to the temperature set, make simultaneously workpiece axial direction due each point cooling evenly, for the homogeneity of the structure property especially hardness improving workpiece after thermal treatment provides guarantee.
