Description

Technical Field

[0001] This utility model is applied in the field of round bar processing and conveying technology, and in particular relates to a feeding and pressing device for a medium frequency furnace. Background Technology

[0002] When processing and rolling round bars, the bars need to be heated in an induction furnace, and then rolled by a rolling mill. Because round bars are long and thin and relatively soft, when the bars are conveyed to the induction furnace for heating and then rolled by the rolling mill, the unstable conveying of the bars can cause poor conveying and prevent them from accurately entering the induction furnace. When the ends of the bars enter the induction furnace for heating, the tail of the bars swings violently when it is bitten and rolled by the subsequent rolling mill, which can easily lead to uneven heating, bending, and affect product quality. Utility Model Content

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] refer to Figures 1-4 This utility model provides a feeding and pressing device for a medium-frequency furnace. A round bar conveying assembly is provided on the front side of the feeding end of the medium-frequency furnace 3. The round bar conveying assembly includes multiple conveying rollers 1 and a conveying roller frame 2. The conveying roller frame 2 consists of two parallel tracks. The multiple conveying rollers 1 are distributed along the length of the conveying roller frame and rotatably connected in the conveying roller frame 2. The multiple conveying rollers 1 are linked together, and the conveying of the round bars is realized by driving the multiple conveying rollers 1 to rotate through a drive motor.

[0029] refer to Figure 3 and Figure 4The pressing device is located at the end of the conveyor roller frame 2 near the medium frequency furnace 3, and includes a drive roller 4, a pressing roller 5, a lifting assembly 6, a sensor 7, and a control assembly 8.

[0030] refer to Figures 1-4 The drive roller 4 is rotatably connected to the conveyor roller frame 2 to support the round bar 9. This drive roller 4 is also linked with multiple conveyor rollers 1 and rotates under the action of a drive motor. An annular groove 10 for limiting the round bar 9 is provided along its circumference on the outer surface of the drive roller 4. When conveying the round bar 9, the round bar 9 is placed in this annular groove 10. Under the action of the annular groove 10, the conveying of the round bar 9 is not easily deviated, making it convenient to convey the round bar 9 to the feed port of the medium frequency furnace 3.

[0031] refer to Figure 3 and Figure 4 The pressure roller 5 is located above the drive roller 4, and the pressure roller 5 and the drive roller 4 work together to press and limit the round bar 9.

[0032] refer to Figure 3 and Figure 4 The lifting assembly 6 is mounted on the conveyor roller frame 2 to drive the pressure roller 5 to move longitudinally. The pressure roller 5 is rotatably connected to the lifting assembly 6. The lifting assembly 6 includes a support frame 61 mounted on the conveyor roller frame 2, a lifting cylinder 62 mounted on the support frame 61, and a pressure roller seat 63 mounted on the telescopic end of the lifting cylinder 62. The pressure roller 5 is rotatably connected to the pressure roller seat 63 via bearings. The support frame 61 is mounted on the conveyor roller frame 2 in a gate shape. The lifting cylinder 62 is inverted and fixed to the top of the support frame 61. The telescopic end of the lifting cylinder 62 slides through the transverse part of the support frame 61 and connects to the pressure roller seat 63. The pressure roller seat 63 is also gate-shaped. The two ends of the pressure roller 5 are rotatably connected to this pressure roller seat 63 via bearings.

[0033] refer to Figure 3 and Figure 4 The lifting assembly 6 also includes a guide member 64 for guiding the pressure roller 5. The guide member 64 includes guide blocks 641 disposed on both sides of the pressure roller seat 63 along its length and a connecting plate 642 connecting the two guide blocks 641. The two ends of the connecting plate 642 are respectively connected to the vertical part of the support frame 61. Limiting grooves 643 are provided on the opposite sides of the two guide blocks 641. The two vertical parts of the pressure roller seat 63 are slidably connected in the corresponding limiting grooves 643. When the lifting cylinder 62 drives the pressure roller 5 to move longitudinally, the limiting grooves 643 provide guidance, improving stability.

[0034] refer to Figure 3 and Figure 4A shock absorber 11 is provided on the upper end face of the pressure roller seat 63, and the telescopic end of the lifting cylinder 62 is connected to the shock absorber 11. Vibration is easily generated when conveying the round bar 9, which can easily damage the lifting cylinder 62. The shock absorber 11 absorbs the vibration, protecting the lifting cylinder 62 and preventing damage. The shock absorber 11 can be a damping spring shock absorber.

[0035] refer to Figure 3 and Figure 4 The connecting plate 642 is located directly below the lifting cylinder 62, and the connecting plate 642 is provided with a guide hole 12 for the extension and retraction end of the lifting cylinder 62 to pass through. This structure not only fixes the guide block 641, but also guides and limits the longitudinal movement of the extension and retraction end of the lifting cylinder 62, thereby improving the stability of the lifting cylinder 62 during operation.

[0036] refer to Figures 1-4 Sensor 7 is mounted on the conveyor roller frame 2 and located between the pressing device and the intermediate frequency furnace 3. The signal output terminal of sensor 7 and the signal receiving terminal of lifting component 6 are both connected to control component 8. Sensor 7 detects whether the round bar 9 has been conveyed to the feed inlet of intermediate frequency furnace 3. When detected, it transmits a signal to control component 8, which controls lifting cylinder 62 to work, thereby driving pressing roller 5 to move down. Under the action of pressing roller 5 and drive roller 4, pressing and limiting of round bar 9 is achieved. After the round bar enters the intermediate frequency furnace for heating, it is conveyed to the biting mouth of the rolling mill (the rolling mill is located on one side of the discharge port of intermediate frequency furnace, not shown in the figure). When the rolling mill rolls the heated round bar 9, under the action of the pressing device, the round bar 9 is not easy to swing, the conveying is relatively stable and convenient, and the heating of the round bar 9 by intermediate frequency furnace 3 is more uniform, improving quality.

[0037] refer to Figures 1-4 The conveyor roller frame 2 is located between the sensor 8 and the drive roller 4, and a conveyor roller 1 is set there. This conveyor roller 1 plays a supporting and guiding role, so that the end of the round bar 9 can enter the medium frequency furnace 3 accurately and smoothly. When the sensor 7 does not detect the round bar 9, the lifting cylinder 62 drives the pressure roller 5 to move upward under the action of the control component 8, so that the drive roller 4 can support and convey the round bar 9 to be processed later.

[0038] In summary, by setting this pressing component on the conveying assembly at the front of the induction furnace feed end, the round bar 9 can be limited and pressed, preventing it from swinging or tilting. This ensures more uniform heating of the round bar inside the induction furnace and improves its quality.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
