Abstract
The invention relates to a quenching furnace which can be used for timely cleaning unqualified workpieces in a quenching process. The quenching furnace comprises a furnace body with a hearth, a circulating mesh belt which is arranged in the hearth and conveys the workpieces from the rear end of the hearth to the front end of the hearth, and a blanking channel which is formed below the front end part of the circulating mesh belt and is communicated with a quenching groove, wherein a cleaning groove which is used for collecting workpieces falling from the circulating mesh belt is also formed below the front end part of the circulating mesh belt; the cleaning groove is positioned behind the blanking channel and is tightly props against the blanking channel; and a workpiece cleaning port is formed on a side wall of a furnace body of the quenching furnace and corresponds to the cleaning groove. According to the quenching furnace, the unqualified workpieces can be timely prevented from dropping into the quenching groove at the beginning of the production so as to enable the unqualified workpieces not to be mixed with normal workpieces in the production process in the prior art, so that the reject ratio of subsequent workpieces is reduced, and the output quality of the whole workpiece is improved.
Description
Technical field
The invention belongs to the HTFX field, particularly relate to a kind of quenching furnance.
Background technology
Workpiece needs in the quenching burner hearth, be heated to 850 ℃ when quenching, and workpiece runs to circulation guipure front end and breaks away from from guipure in burner hearth, falls in the quenching tank through blanking channel, rises and accomplishes quenching process through the quenching tank raising legs; When transmitting on the circulation guipure of workpiece in burner hearth; There are a small amount of workpiece and guipure bonding; Can not in time drop in the quenching tank, quenching furnance of the prior art can overstock the place, slit between guipure and blanking channel with the workpiece that can not in time drop in the quenching tank; Be under the overstocked workpiece temperature at place, slit between guipure and the blanking channel and be reduced to quenching temperature, will produce hardness and wear resistance raw material not up to standard after dropping in the oil-quenching tank; For the demanding workpiece of quality product, the condemnation factor of ppt appears immediately, and also serious quality problems can be produced, even economic disputes such as claim can be caused.
Summary of the invention
The purpose of this invention is to provide a kind of can the defective workpiece that does not in time fall into blanking channel the separation with normal workpiece, and be convenient to clear up the quenching furnance of defective workpiece in the quenching process.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of quenching furnance, it comprises body of heater with burner hearth, be arranged in the described burner hearth and by the circulation guipure of the rear end forward end transmission workpiece of described burner hearth, the blanking channel that is arranged on described circulation guipure leading section below and is connected with quenching tank; Be used to collect the cleaning groove of workpiece of dropping on the described circulation guipure also being provided with below the described circulation guipure leading section; Described cleaning groove is positioned at described blanking channel rear; And near described blanking channel; On described quenching furnance sidewall of the furnace body, offer the workpiece clean-up port, described workpiece clean-up port is corresponding with the position of described cleaning groove.
In the preferred version, bottom-up the extending back gradually of the top part rear surface of described blanking channel forms the workpiece baffle plate.
In the preferred version; Described body of heater front portion is provided with first rotor wheel; Described body of heater rear portion is provided with second rotor wheel; Described circulation guipure is stretched on described first rotor wheel and described second rotor wheel, and on horizontal plane, the distance that the upper end of described workpiece baffle plate overlaps with the projection of described first rotor wheel is that described first rotor wheel rotates the half the of diameter.
In the preferred version, described cleaning groove extends to an other side from described burner hearth one side, and the length that described cleaning groove groove width is extended in the horizontal direction is the sesqui that described first rotor wheel rotates diameter.
In the preferred version, be provided with door at described sidewall of the furnace body, described door covers on described workpiece clean-up port.
Principle of work of the present invention is:
After heating up, workpiece gets into blanking channel through the circulation guipure in the quenching furnance burner hearth; Fall in the quenching tank at last; Wherein a small amount of and circulation guipure adherent workpiece is taken back again to be got in the burner hearth; And drop in the cleaning groove, the staff can regularly open the workpiece cleaning door and defective workpiece is taken out from the workpiece clean-up port scrap.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
The present invention is through being provided with the cleaning groove, and the feasible and a small amount of workpiece of guipure adherent can not overstock the place, slit between guipure and blanking channel, and directly drops in the cleaning groove; Therefore defective in process of production workpiece in time initially just can separate with normal workpiece and reclaim in generation, reduces the product fraction defective.
Description of drawings
Accompanying drawing 1 is the structural representation at quenching furnance discharge port of the prior art place;
Accompanying drawing 2 is the structural representation at quenching furnance discharge port of the present invention place;
In the above accompanying drawing: 1, body of heater; 11, burner hearth; 2, blanking channel; 21, workpiece baffle plate; 3, circulation guipure; 4, quenching tank; 5, cleaning groove; 6, workpiece clean-up port; 7, first rotor wheel.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described that (this specification sheets described " length direction " is meant in the accompanying drawing 2 perpendicular to the inside direction of paper; This specification sheets described " the place ahead " is meant the right side in the accompanying drawing 2; " rear " is meant the left side in the accompanying drawing 2, and this specification sheets described " top ", " below " and the upper and lower shown in the accompanying drawing 2 are to identical):
Quenching furnance of the present invention is as shown in Figure 2, and it comprises body of heater 1 with burner hearth 11, be arranged in the described burner hearth 11 and by the circulation guipure 3 of the rear end forward end transmission workpiece of described burner hearth 11, the blanking channel 2 that is arranged on described circulation guipure 3 leading sections below and is connected with quenching tank 4.Described body of heater 1 front portion is provided with first rotor wheel 7; Described body of heater 1 rear portion is provided with the second rotor wheel (not shown); Described circulation guipure 3 is stretched on described first rotor wheel 7 and the described second rotor wheel (not shown), and bottom-up the extending back gradually of the top part rear surface of described blanking channel 2 forms workpiece baffle plate 21.On horizontal plane, the distance that the upper end of described workpiece baffle plate 21 overlaps with the projection of described first rotor wheel 7 is that described first rotor wheel 7 rotates the half the of diameter.The benefit of doing like this is to guarantee a large amount of workpiece abundant blanking when temperature does not descend.
