Detailed Description

Referring to fig. 1, a small-size metal work piece quenching line, include material loading area 1, connect heating furnace 2, setting behind the material loading area 1 are in the quenching groove 3 and the material loading end that just are equipped with fluid of heating furnace 2 below submerge in quenching groove 3 and aim at the promotion guipure 4 of heating furnace 2 blanking mouth, the unloading end of promotion guipure 4 exceeds quenching groove 3 and blanking are to a continuous deoiling machine 5, continuous deoiling machine 5 is connected with blown down tank 51 and oil pipe 52, oil pipe 52 backward flow to quenching groove 3.

The utility model discloses a small-size metal work piece quenches line adopts continuous deoiling machine to degrease for small-size metal work piece, and small-size metal work piece is derived from the blown down tank after the deoiling, can put through toward the conveyer belt or the collecting box of packing behind the blown down tank, and the oil reflux that the play oil pipe came out with the centrifugation is in quenching the groove, makes the continuous surface treatment that the production line can realize small-size metal work piece, is favorable to reducing intensity of labour, practices thrift the human cost, improves machining efficiency.

Near heating furnace 2 blanking mouth, owing to have continuously by the small-size metal parts who has heated to fall down, quench groove 3 local temperature in this place and quench the groove 3 other local temperature and want to be higher, the utility model discloses make following improvement in this respect, the top of quenching groove 3 is striden and is equipped with support 61, be provided with agitator motor 6 on the support 61, be connected with stirring rake 62 on agitator motor 6's the output, stirring rake 62 floods in the fluid of quenching groove 3 and is located near heating furnace 2 blanking mouth. Under the stirring of the stirring paddle 62, the temperature of all parts of the quenching tank 3 can be rapidly balanced, and the temperature near the blanking port of the heating furnace 2 is ensured to be low enough to ensure the quenching effect.

The oil liquid contacted with the small metal parts may be consumed by the liquid medicine or be contaminated by a small amount of impurities, and the oil outlet pipe 52 flows to the outlet of the quenching tank 3 near the stirring paddle 62, so that the recovered oil liquid can be rapidly and uniformly mixed with the oil liquid in the quenching tank 3. In addition, when it is necessary to add a chemical solution to the quenching bath 3, the paddle 62 can diffuse the chemical solution uniformly.

The patent document with publication number "CN 205164974U" discloses a centrifugal deoiling machine capable of realizing continuous deoiling and applicable to the present invention as a continuous deoiling machine 5. And simultaneously, the utility model discloses the better continuous deoiling machine of performance is as follows also provided.

Referring to fig. 2, the continuous oil removing machine 5 includes a feeding funnel 53, a rotary barrel 54 disposed below the feeding funnel 53, an oil drum 55 disposed at the periphery of the rotary barrel 54, and a charging basket 56 disposed at the periphery of the oil drum 55, wherein the rotary barrel 54 is connected to a driving motor 57, the oil drum 55 is communicated with the oil outlet pipe 52 at the bottom, the bottom of the charging basket 56 is communicated with the discharge chute 51, a plurality of filtering holes penetrating through the inner and outer walls of the rotary barrel 54 are distributed on the rotary barrel 54, and the inner diameter of the rotary barrel 54 gradually increases from the bottom to the top. After the small metal parts fall into the rotary barrel 54 through the feeding hopper 53, under the high-speed centrifugation of the rotary barrel 54, oil liquid is thrown into the oil barrel 55 and then flows to the oil outlet pipe; the small metal parts are centrifuged in the rotating barrel 54 with a narrow lower part and a wide upper part, gradually move upwards, then fall out of the rotating barrel 54 into the charging barrel 56, and finally are discharged from the discharging groove.

The bottom of the charging bucket 56 is provided with an inclined plate 561, the inclined plate 561 is connected with the discharging groove 51, and all small metal parts slide to the discharging groove by the inclined plate 561.
