Currently, bar heat treatment equipment operates in a high-temperature environment and has a low degree of automation.

[0037] As attached Figure 1 -Attached Figure 5 As shown, the present invention provides a bar heat treatment device, comprising a heating device 1, a bar heating wheel 2, a material limiting plate I 3 and a cooling box 4;

[0038] The wheel wall of the bar heating wheel 2 is provided with a notch I201 for fitting the bar, and the material limiting plate I3 includes a semicircular section 301 provided on the lower side of the bar heating wheel 2 and a vertical section 302 provided on one side of the bar heating wheel 2. The wheel wall of the bar heating wheel 2 and the material limiting plate I3 are spaced in the same manner. When the notch I201 rotates to the material limiting plate I3, the material limiting plate I3 limits the notch I201, so that the bar 18 to be heat treated is always in the notch I201 and continues to rotate with the bar heating wheel 2.

[0039] The bottom of the bar heating wheel 2 and the bottom of the semicircular segment 301 are placed in the cooling box 4. At this time, when the notch I 201 rotates to the bottom of the semicircular segment 301, the notch I 201 and the bar to be heat-treated 18 in the notch I 201 will also enter the cooling box 4 for cooling;

[0040] The tangent area above the bar material 18 to be heat treated, the wall of the bar material heating wheel 2 and the vertical section 302 is the bar material heating zone 5, and the heating device 1 heats the bar material heating zone 5;

[0041] The bar heating wheel 2 rotates, and the bar to be heat treated 18 in the bar heating zone 5 is driven by the rotating wheel wall of the bar heating wheel 2 to rotate and is heated by the heating device 1. At this time, the heating device 1 continues to heat the bar to be heat treated 18, and the bar heating wheel 2 drives the bar to be heat treated 18 to rotate all the time, which can greatly ensure the heating uniformity of the bar to be heat treated 18 and ensure the heat treatment effect. Until the gap I 201 rotates to the bar heating zone 5, the bar to be heat treated 18 falls into the gap I 201 and enters the cooling box 4 for cooling under the limit of the semicircular segment 301. Under the continuous rotation of the gap I 201, the gap I 201 drives the bar to be heat treated 18 to move upward to the other side of the semicircular segment 301 and leaves the cooling box 4. Finally, when the gap I 201 rotates to the other end away from the semicircular segment 301, the gap I 201 loses its restraint, and the bar to be heat treated 18 falls out of the gap 21 by gravity and enters the next workstation.

[0042] The bar heat treatment device provided by the present invention can drive the bar 18 to be heat treated to rotate by the rotation of the bar heating wheel 2, thereby improving the uniformity of heating. At the same time, during the rotation process, the bar 18 to be heat treated can be driven to the cooling box 4 through the notch 21 for cooling and then leaving the cooling box 4, thereby realizing the heating and cooling heat treatment operations of the bar 18 to be heat treated. The entire rotation and conveying device of the bar 18 to be heat treated is the bar heating wheel 2. The overall structure is simple and does not require a conveying mechanism or a clamping mechanism to replace it, thereby realizing the automatic heating and cooling heat treatment operations of the bar 18 to be heat treated. In addition, when the bar 18 to be heat treated falls into the notch I 201, the bar heating zone 5 can immediately load a new bar 18 to be heat treated, thereby realizing continuous heating of the heating device 1 without stopping, avoiding the frequent start and stop of the heating device 1 to waste cold resources, and greatly improving the continuity and heat treatment efficiency of the heat treatment of multiple bar 18 to be heat treated.

[0043] In one embodiment, the bar heating wheel 2 can move back and forth toward the cooling box 4. In this embodiment, the semicircular segment 301 moves with the bar heating wheel 2, but does not rotate with the bar heating wheel 2. Specifically, the semicircular segment 301 is rotatably arranged on the rotating shaft of the bar heating wheel 2 through the mounting member 3011, but the mounting member 3011 is relatively stationary, but the rotating shaft of the bar heating wheel 2 continues to rotate. In addition, a guide plate 3012 is provided at the exit of the other end of the semicircular segment 301. When the guide plate 3012 rotates to leave the other end of the semicircular segment 301 in the notch Ⅰ201, the bar 18 to be heat treated will not fall into the cooling box 4, but will be guided to fall into the next workstation. When the bar heating wheel 2 can move back and forth toward the cooling box 4, the guide plate 3012 can be a telescopic plate, and one end is hinged to the other end of the semicircular segment 301, and the other end is hinged to the outer wall of the box opening of the cooling box 4. With this arrangement, the bar heating wheel 2 can move downward toward the cooling box 4, and the depth to which the bar heating wheel 2 enters the cooling box 4 can be adjusted. This allows the cooling time of the bar 18 to be heat-treated to be adjusted while maintaining a constant rotational speed of the bar heating wheel 2. This allows for adapting to different cooling requirements.

[0044] In one embodiment, the upper end of the cooling box 4 is provided with an opening for the rod heating wheel 2 and the semicircular end 301 to enter and exit, and a static or flowing coolant is provided in the box, so that the heated rod 18 to be heat treated is immersed in the coolant for rapid cooling.

[0045] In one embodiment, the heating device 1 moves in coordination with the bar heating wheel 2, that is, when the bar heating wheel 2 moves back and forth toward the cooling box 4, the heating device 1 also moves in coordination so that it always acts on the bar heating zone 5 for heating. In this embodiment, when the bar 18 to be heat treated falls into the gap I 201, the bar heating zone 5 can immediately load a new bar 18 to be heat treated. At this time, even if the bar heating wheel 2 moves back and forth toward the cooling box 4, the heating device 1 can continue to heat the new bar 18 to be heat treated in the bar heating zone 5, so that the heating device 1 can achieve continuous heating without stopping, avoid frequent starting and stopping of the heating device 1 to waste cold resources, and greatly improve the continuity and efficiency of the heat treatment of multiple bar 18 to be heat treated.

[0046] In one embodiment, the bar heat treatment device further includes a tempering wheel 6, a material limiting plate II 7 and a tempering heating device 8;

[0047] The wheel wall of the tempering wheel 6 is provided with a notch II 601 for fitting the bar, and the material limiting plate II 7 is provided on one side of the tempering wheel 6. The tangent area above the bar 18 to be heat treated, the wheel wall of the tempering wheel 6 and the material limiting plate II 7 is the bar tempering zone 9, and the tempering heating device 8 heats the bar tempering zone 9.

[0048] The next station is the bar tempering zone 9, that is, after the heat treatment bar 18 is heated and cooled, the heat treatment bar 18 is heated again, which can realize the bar tempering operation, that is, quenching and high temperature tempering;

[0049] Specifically, the tempering wheel 6 rotates, and the bar 18 to be heat treated in the bar tempering zone 9 rotates on its own, driven by the rotating wheel wall of the tempering wheel 6, and is heated by the tempering heating device 8. This improves the uniformity of the tempering heating of the bar 18 to be heat treated. Until the gap II 601 rotates to the bar tempering zone 9, the bar 18 to be heat treated falls into the gap II 601. When the gap I 201 rotates away from the material retaining plate II 7, the bar 18 to be heat treated falls out of the gap II 601 to the discharge station due to gravity. In this embodiment, the tempering temperature and time can be controlled by controlling the speed of the tempering wheel 6 and the heating temperature of the tempering heating device 8. The tempering wheel 6 is driven by an independent rotary drive member II 16, preferably a motor. In the embodiment with the guide plate 3012, the guide plate 3012 and the material retaining plate II 7 are separated to form a bar movement channel.

[0050] In one embodiment, the bar heat treatment device further includes a loading wheel 10 and a loading chamber 11;

[0051] A material outlet 1101 is provided at the bottom of the loading chamber 11, and the wheel wall of the loading wheel 10 blocks the material outlet 1101. A notch III 1001 for fitting the bar is provided on the wheel wall of the loading wheel 10. When the wheel wall of the loading wheel 10 blocks the material outlet 1101, the bar 18 to be heat-treated in the loading chamber 11 remains stationary. After the notch III 1001 rotates into the loading chamber 11, a bar 18 to be heat-treated falls into the notch III 1001, and is then taken out of the loading chamber 11 when the notch III 1001 rotates to the outside of the material outlet 1101. The upper end of the vertical section 302 extends to one side of the material outlet 1101. At this time, when the notch III 1001 brings the bar 18 to be heat-treated out of the loading chamber 11, it is limited by the vertical section 302 and directly falls into the bar heating zone 5.

[0052] A plurality of bars 18 to be heat treated are stacked in the loading chamber 11. The loading wheel 10 rotates. When the gap III 1001 rotates from the material outlet 1101 to the vertical section 302, a bar 18 to be heat treated in the loading chamber 11 embedded in the gap III 1001 falls into the bar heating zone 5. In this way, the automatic loading of the bar 18 to be heat treated can be realized, simplifying the loading process.

[0053] In one embodiment, the loading wheel 10 and the bar heating wheel 2 rotate synchronously, thereby ensuring the coordinated loading and heating of the bar 18 to be heat-treated. After the notch I 201 of the bar heating wheel 2 receives a bar 18 to be heat-treated that has been heated, the loading wheel 10 then loads the bar 18 to be heat-treated in a loading cavity 11 into the bar heating zone 5, ensuring the continuous operation of the heating device 1 and improving the utilization rate of the heating device 1.

[0054] In this embodiment, the bar heat treatment device also includes a rotary drive mechanism 12, a feeding wheel mounting frame 13 and a bar heating wheel mounting frame 14, the rotary drive mechanism 12 includes a rotary drive member I1201, a driving wheel 1202 that rotates with the rotary drive member I1201, and a driven wheel 1203 that meshes with the driving wheel 1202, the bar heating wheel mounting frame 14 is hingedly arranged on one side of the feeding wheel mounting frame 13, the feeding wheel 10 is arranged on the feeding wheel mounting frame 13 and is connected to the shaft of the driving wheel 1202, and the bar heating wheel 2 is arranged on The bar heating wheel mounting frame 14 is connected to the driven wheel 1203 through a flat eccentric coupling 1024. With this arrangement, the rotating drive component I1201 can drive the active wheel 1202 and the driven wheel 1203 to rotate synchronously, thereby driving the loading wheel 10 and the bar heating wheel 2 to rotate synchronously. At the same time, the bar heating wheel 2 can rotate around the hinge, thereby realizing reciprocating movement toward the cooling box 4. The rotating drive component I1201 preferably adopts a motor, which can reduce the number of rotating drive components I1201 and ensure that the loading wheel 10 and the bar heating wheel 2 rotate synchronously.

[0055] In one embodiment, the feeding wheel mounting frame 13 and the bar heating wheel mounting frame 14 are provided with a telescopic mechanism 17 at one end away from the hinge. The telescopic mechanism 17 preferably adopts a cylinder or a hydraulic cylinder. One end of the telescopic mechanism 17 is hinged to the feeding wheel mounting frame 13, and the other end is hinged to the bar heating wheel mounting frame 14. The telescopic mechanism 17 is extended and retracted to drive the bar heating wheel mounting frame 14 and the bar heating wheel 2 to rotate.

[0056] In one embodiment, the heating device 1 includes a rotating mounting frame 101 rotatably arranged on the bar heating wheel mounting frame 14, a flamethrower 102 arranged on the rotating mounting frame 101, and an angle adjustment rod 103 hinged to the rotating mounting frame 101 and the feeding wheel mounting frame 13. The angle adjustment rod 103 is preferably a telescopic rod. Through the extension and retraction of the angle adjustment rod 103, the angle adjustment rod 103 can make the flamethrower 102 always spray fire toward the bar heating zone 5. In this embodiment, the flamethrower 102 can move with the bar heating wheel 2, so that when the bar heating wheel 2 moves toward the cooling box 4, the flamethrower 102 always sprays fire on the bar heating zone 5.

[0057] In one embodiment, the bar heat treatment device also includes a vertical mounting plate 15, the rotary drive mechanism 12, the loading wheel mounting frame 13 and the bar heating wheel mounting frame 14 are arranged on one side of the vertical mounting plate 15, and the loading wheel 10, the loading chamber 11, the heating device 1, the bar heating wheel 2, the material limiting plate I3 and the cooling box 4 are arranged on the other side of the vertical mounting plate 15. In the embodiment with the tempering wheel 6, the material limiting plate II7 and the tempering heating device 8, the tempering wheel 6, the material limiting plate II7 and the tempering heating device 8 are also arranged on this side of the vertical mounting plate 15.

[0058] The present invention also provides a bar heat treatment method, using the above-mentioned bar heat treatment device, comprising the following steps:

[0059] A plurality of bars 18 to be heat-treated are stacked in the loading chamber 11. The loading wheel 10 rotates, and when the notch III 1001 rotates from the material outlet 1101 to the vertical section 302, a bar 18 to be heat-treated in the loading chamber 11 is embedded in the notch III 1001 and falls into the bar heating zone 5.

[0060] The bar heating wheel 2 rotates, and the bar 18 to be heat treated in the bar heating zone 5 rotates driven by the rotating wheel wall of the bar heating wheel 2 and is heated by the heating device 1 until the gap I 201 rotates to the bar heating zone 5, and the bar 18 to be heat treated falls into the gap I 201 and enters the cooling box 4 for cooling under the limit of the semicircular segment 301. When the gap I 201 rotates to leave the other end of the semicircular segment 301, the bar 18 to be heat treated falls out of the gap 21 by gravity and enters the next workstation.

[0061] When the next station is bar tempering zone 9;

[0062] The tempering wheel 6 rotates, and the bar to be heat treated 18 in the bar tempering zone 9 rotates driven by the rotating wheel wall of the tempering wheel 6 and is heated by the tempering heating device 8 until the gap II 601 rotates to the bar tempering zone 9, and the bar to be heat treated 18 falls into the gap II 601. When the gap I 201 rotates to leave the material limiting plate II 7, the bar to be heat treated 18 falls out of the gap II 601 to the discharge station by gravity.

[0063] The present application can automatically realize the loading, heating, cooling, heating, and unloading operations of the bar material 18 to be heat treated, thereby automatically performing the tempering treatment of the bar material, thereby eliminating manual loading and unloading.
