a precession type heating furnace comprises a furnace body, wherein a feeding roller channel for feeding a wheel hub into the furnace is horizontally arranged at the top of the furnace body, a spiral roller channel for receiving the wheel hub from the feeding roller channel and spirally conveying the wheel hub to the bottom of the furnace body is arranged on the furnace body, and a discharging roller channel for receiving the wheel hub from the spiral roller channel and conveying the wheel hub out of the furnace is horizontally arranged at the bottom of the furnace body.
Furthermore, the spiral roller way comprises a plurality of roller rods which are spirally and uniformly arranged along the circumferential surface of the furnace body, the sectional area of a part of any roller rod extending into the furnace body is gradually reduced from outside to inside, the transmission part of any roller rod positioned outside the furnace body is fixed on the outer wall surface of the furnace body through a bearing seat and a support connecting piece, and the roller rods are driven by a chain.
Furthermore, the taper angle of the part of any roller extending into the furnace body is 2-4 degrees.
Further, the screw-in heating furnace further comprises a feeding lifting mechanism for lifting the hub and conveying the hub to the feeding roller way.
Further, the screw-in heating furnace further comprises a discharging robot for discharging the wheel hub on the discharging roller way and transferring to the next working procedure.
The beneficial effects of the utility model reside in that:
1) the utility model discloses reduced business turn over material door (top material loading roll table and bottom ejection of compact roll table respectively one), can reduce the influence (the temperature fluctuation is little) of opening the door to the furnace temperature, the energy can be saved, the wheel hub work piece can be heated by whole uniformly, is favorable to improving thermal treatment quality. Meanwhile, the hub workpiece is uniformly fed into the furnace through the feeding roller channel, all products are subjected to heat treatment in the same channel, and the performance consistency of all products can be ensured.
2) The utility model discloses a precession formula heating furnace is structurally more compact for traditional heating furnace, and area is little, and the fault rate is lower, and the reliability is higher, is favorable to reducing investment cost, improves enterprise competitiveness. The spiral roller way roller rod transmission mechanism is arranged outside the furnace body, and does not need to enter the furnace during maintenance, thereby being beneficial to reducing the time for troubleshooting and maintenance and ensuring the safety of personnel.

Detailed Description
The screw-type heating furnace of the present invention will be described in further detail with reference to the accompanying drawings and specific examples.
As shown in fig. 1 and 3, the precession type heating furnace comprises a furnace body, wherein a feeding roller way 3 for feeding a wheel hub 1 into the furnace is horizontally arranged at the top of the furnace body, a spiral roller way 4 for receiving the wheel hub 1 from the feeding roller way 3 and spirally conveying the wheel hub to the bottom of the furnace body is arranged on the furnace body, and a discharging roller way 5 for receiving the wheel hub 1 from the spiral roller way 4 and conveying the wheel hub out of the furnace is horizontally arranged at the bottom of the furnace body.
Specifically, the spiral roller table 4 includes a plurality of roller rods uniformly arranged along the circumferential surface of the furnace body in a spiral shape, and a partial sectional area of any roller rod extending into the furnace body is gradually reduced from outside to inside, in this embodiment, a partial taper angle of any roller rod extending into the furnace body is 2 ° to 4 °, see fig. 2. Any transmission part of the roller rod, which is positioned outside the furnace body, is fixed on the outer wall surface of the furnace body through a bearing seat and a bracket connecting piece, and the roller rod is transmitted through a chain (the mode of fixing through the bearing seat and the bracket connecting piece is the prior art).
In addition, the screw-in heating furnace further comprises a feeding lifting mechanism 2 for lifting and conveying the wheel hub 1 to the feeding roller way 3 and a discharging robot 6 for discharging the wheel hub 1 on the discharging roller way 5 and transferring to the next procedure (the feeding lifting mechanism 2 and the discharging robot 6 are both in the prior art).
