Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a furnace discharge device. Background Technology

[0002] To improve the quality of steel section rolling, round steel is used as the billet and heated inside an electric heating furnace. The heating temperature is uniform, and the rolled surface quality is good. After heating, the round steel needs to be transported from the electric heating furnace to the subsequent processing steps through the coordinated operation of the track frame and guide plate.

[0003] In actual production, when round steel bars detach from the track frame and fall into the guide plate, their own weight and the gravitational potential energy generated by the falling height create a continuous and strong impact on the surface of the guide plate. Under long-term, high-frequency production operations, this impact will inevitably lead to problems such as dents, deformation, and even damage to the guide plate, seriously affecting the normal operation and service life of the equipment. Currently, some existing post-furnace discharge devices use thickened guide plates to enhance their impact resistance. Increasing the thickness of the guide plate can indeed improve its ability to withstand the impact of round steel bars to a certain extent, ensuring that the guide plate is not easily damaged during use. However, thickening the guide plate means consuming more raw materials. Furthermore, during processing and manufacturing, the increased plate thickness also increases the processing difficulty and technological requirements, directly leading to a significant increase in manufacturing costs and increasing the production cost burden on enterprises. Therefore, this application provides a post-furnace discharge device to meet this need. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a furnace discharge device to solve the problem that the existing furnace discharge device has increased processing difficulty and process requirements, and increased manufacturing cost due to the thickening of the guide plate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A furnace discharge device includes a track frame installed at the discharge end of an electric heating furnace, a guide plate being snapped onto the end of the track frame away from the electric heating furnace, and a conveying roller conveyor being installed on the end of the guide plate away from the track frame; and a protection component for protecting the guide plate, the protection component being connected to the guide plate.

[0007] Optionally, the protective component includes a protective plate, which is slidably connected to the bottom of the guide plate, and a telescopic rod is fixedly connected to the bottom of the protective plate.

[0008] Optionally, both sides of the protective plate are fixedly connected with flanges, and a weakening groove is provided on the top of the flanges.

[0009] Optionally, the thickness of the flange is less than the thickness of the protection plate, and the flange is sleeved on both sides of the guide plate.

[0010] Optionally, the middle part of the guide plate is concave downward, and the cross section is V-shaped, and the guide plate is an arc plate as a whole.

[0011] Optionally, the top profile of the protection plate matches the bottom profile of the guide plate.

[0012] Optionally, the guide plate is fixedly connected with a clamping plate at the bottom near one end of the track frame, and the clamping plate is internally provided with a weakened groove.

[0013] Optionally, the clamping plate is internally provided with a clamping groove at the connecting position with the track frame.

[0014] Optionally, the track frame is rotatably connected with a roller at the top, and the roller is V-shaped.

[0015] Optionally, the guide plate and the protection plate are both stamping-formed iron plates.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting the protection assembly, the protection plate is designed with a small flange thickness and a weakened groove, and through simple extrusion operation, the flange is expanded outward to complete the clamping with the guide plate, which is convenient and fast to install. At the same time, the protection plate can be flexibly moved according to the round steel drop point. When the round steel falls on the surface of the guide plate, the protection plate can effectively buffer the impact force of the round steel, avoid the guide plate from being damaged due to long-term bearing of the impact of the round steel, such as concave, prolong the service life of the guide plate, reduce the equipment maintenance and replacement frequency, reduce the equipment operation cost. At the same time, the guide plate and the protection plate are both stamping-formed iron plates, the manufacturing process is simple, the cost is low, the telescopic rod can not only fix the position of the protection plate, but also can additionally support the guide plate, further enhance the bearing capacity and stability of the guide plate, improve the reliability of the whole device, and ensure the normal operation of the equipment under long-time and high-intensity working condition.

[0018] By incorporating a guide plate with a concave central section and a V-shaped cross-section, the round steel bars are precisely positioned to prevent tilting as they move along the guide plate surface, ensuring accurate and stable transport. The guide plate itself is arc-shaped, connecting to the track frame at one end and located at the feed inlet of the conveyor rollers at the other. This ingenious arc design facilitates the reversal of the round steel bars, allowing them to smoothly enter the conveyor rollers and preventing blockages or falls due to directional deviations. Simultaneously, the V-shaped rollers on the track frame effectively restrict the movement of the round steel bars, preventing them from falling due to tilting during forward transport driven by the motor. This ensures the safety and stability of the round steel transport, improves material conveying efficiency, reduces downtime and cleaning time caused by fallen round steel bars, and guarantees the continuity of the production process.

[0033] like Figures 1 to 5As shown, an embodiment of this utility model provides a furnace discharge device, including a track frame 2 installed at the discharge end of an electric heating furnace 1. The electric heating furnace 1 is a prior art device used for heating round steel. A guide plate 4 is snapped onto the end of the track frame 2 away from the electric heating furnace 1, and a conveying roller 6 is installed on the end of the guide plate 4 away from the track frame 2. A protective component is also included, which is used to protect the guide plate 4. The protective component is connected to the guide plate 4. By setting the protective component, the protective plate 5 utilizes a design with a small flange thickness and a weakening groove. Through a simple extrusion operation, the flange expands outward to complete the snapping with the guide plate 4, making installation convenient and quick. At the same time, the protective plate 5 can flexibly move its position according to the landing point of the round steel. When the round steel falls onto the surface of the guide plate 4, the protective plate 5 can effectively buffer the impact force of the round steel, preventing the guide plate 4 from being damaged such as dents due to long-term impact from the round steel, extending the service life of the guide plate 4, reducing the frequency of equipment maintenance and replacement, and reducing equipment operating costs. In addition, both the guide plate 4 and the protective plate 5 are stamped iron plates, with simple manufacturing processes and low costs.

[0034] like Figure 1 and Figure 2 As shown, the protective assembly includes a protective plate 5, which is slidably connected to the bottom of the guide plate 4. A telescopic rod 501 is fixedly connected to the bottom of the protective plate 5. The telescopic rod 501 is existing technology and will not be described in detail here. Both sides of the protective plate 5 are fixedly connected with flanges, and the top of the flanges has a weakening groove. The thickness of the flanges is less than the thickness of the protective plate 5. The flanges are sleeved on both sides of the guide plate 4. In use, the protective plate 5 is first placed at the bottom of the guide plate 4. Then, one side of the flange is first clamped to one end of the guide plate 4. The protective plate 5 is then pressed upward. Due to the lower thickness of the flange, it will expand outward, and the other end will also clamp the guide plate 4. At this time, the protective plate 5 can be moved to the corresponding position according to the landing point of the round steel to ensure that the round steel will not cause a dent to the guide plate 4 when it lands on the surface of the guide plate 4. Then, the position of the protective plate 5 is fixed by the telescopic rod 501, which also provides support for the guide plate 4. The middle part of the guide plate 4 is recessed downwards, and the cross section is "V" shaped to ensure that the round steel does not tilt when it is on the surface of the guide plate 4. The guide plate 4 is an arc plate as a whole, with one end connected to the track frame 2 and the other end at the feed inlet of the conveyor roller 6, which makes it easy to turn the round steel so that it can smoothly enter the conveyor roller 6. The top contour of the protective plate 5 matches the bottom contour of the guide plate 4. Both the guide plate 4 and the protective plate 5 are stamped iron plates, which are simple to manufacture and have low cost.

[0035] like Figures 3 to 5As shown, a snap-fit ​​plate 401 is fixedly connected to the bottom of the guide plate 4 near the bottom of the track frame 2. The snap-fit ​​plate 401 has a weakening groove inside. A slot is provided at the connection position between the snap-fit ​​plate 401 and the track frame 2. The snap-fit ​​plate 401 snaps into the slot. When installing the guide plate 4, the snap-fit ​​plate 401 can be aligned with the slot and pressed down. The snap-fit ​​plate 401 will be recessed inward due to the weakening groove, thus entering the slot and completing the fixation. Rollers 3 are rotatably connected to the top of the track frame 2. Both the track frame 2 and the rollers 3 are existing technologies. Multiple sets of rollers 3 are evenly arranged on the roller frame. One end of the roller 3 is connected to a sprocket. The sprocket is connected to the motor through a chain. The roller 3 rotates with the motor through the chain. The roller 3 is V-shaped, so that the round steel will not fall due to tilting during the conveying process. After heating, the round steel is pushed onto the roller 3 and conveyed forward to the guide plate 4 under the drive of the motor.

[0036] The workflow of the technical solution provided by this utility model is as follows:

[0037] In use, first align the locking plate 401 of the guide plate 4 near the track frame 2 with the slot, and press down on the guide plate 4. The locking plate 401 will be recessed inward due to the weakening groove, thus entering the slot and completing the fixation. Then, place the protective plate 5 at the bottom of the guide plate 4, first locking one side of the flange onto one end of the guide plate 4, and then pressing the protective plate 5 upward. Due to the low thickness of the flange, it will expand outward, thus locking the other end of the guide plate 4. At this time, the protective plate 5 can be flexibly moved to the corresponding appropriate position according to the actual landing point of the round steel. The purpose of doing this is to ensure the round steel is properly secured. When the steel falls onto the surface of the guide plate 4, the protective plate 5 acts as a buffer and protector, preventing the impact of the round steel from causing damage such as dents to the guide plate 4, thereby extending the service life of the guide plate 4. The position of the protective plate 5 can be fixed by the telescopic rod 501, which also supports the guide plate 4. The round steel is heated by the electric heating furnace 1. After heating, the round steel is pushed onto the roller 3 and conveyed forward to the guide plate 4 under the drive of the motor. Since the roller 3 is V-shaped, the round steel will not fall due to tilting during the conveying process. The round steel smoothly enters the conveying roller 6 through the guide plate 4.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
