Description

Technical Field

[0001] The utility model belongs to the technical field of heating furnace feeding, in particular to a horizontally advancing feeding structure of a square embryo heating furnace. Background Art

[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the temperature required for rolling or forging. Heating furnaces are used in many industries, including petroleum, chemical engineering, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals.

[0003] Medium-frequency heating furnaces for billets play a vital role in hot rolling production lines due to their simple operation, compact footprint, and high efficiency. To facilitate transport, some production lines utilize inclined rollers, allowing the billets to slide downward under their own weight. This method requires no power source, boasts a simple structure, consumes no energy, and is convenient and fast. However, after heating in the heating furnace, the billets must be positioned in an upright position to facilitate grasping by a robotic arm at the rear end and forwarding to the next process. This requires a mechanism to transition the billets from tilted transport to upright placement, and the device designed in this paper addresses this issue. Summary of the Invention

DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1 to 3As shown, the utility model is a horizontal push feeding structure of a square blank heating furnace, comprising a chain plate conveyor 3, a pushing mechanism 1 and a detection mechanism 2; the end of the chain plate conveyor 3 is provided with a horizontal push position, and a feeding position is provided next to the horizontal push position near the feeding port of the heating furnace; the pushing mechanism 1 comprises a horizontal push cylinder 11 provided on one side of the horizontal push position, and a feeding cylinder 12 provided on one side of the feeding position, the telescopic rod of the horizontal push cylinder 11 is horizontally aligned with the horizontal push position, and is used to push the square blank 4 at the horizontal push position to the feeding position, and the feeding cylinder 12 is provided on the other side of the feeding position. The telescopic rod is aligned with the feed port of the heating furnace, and is used to push the square blank 4 at the feed position into the heating furnace; the push cylinder 11 and the feed cylinder 12 are both controlled by a controller; the detection mechanism 2 includes a transmission material detector 21 arranged near the push position, and a push material detector 22 arranged near the feed position. The transmission material detector 21 and the push material detector 22 are both connected to the controller circuit, and are used for controlling the push cylinder 11 and the feed cylinder 12 to work when signals of the square blank 4 reaching the push position and the feed position are detected respectively.

[0018] In the above technical solution, the square blank 4 is transferred to the chain conveyor 3 through the inclined roller transmission roller. The square blank 4 becomes a straightened square blank due to its own gravity and is transferred to the end of the chain conveyor 3 by the chain conveyor 3. The transmission material detector 21 detects the square blank 4 and transmits a signal to the controller. The controller controls the push cylinder 11 to push the straightened square blank 4 to the front end of the feed cylinder 12. The push material detector 22 detects the square blank 4 and transmits a signal to the controller. The feed cylinder 12 is then controlled by the controller program to work, and the straightened square blank 4 is pushed into the heating furnace to start heating, and then this cycle is repeated. When the material at the outlet of the heating furnace is out of the heating furnace, it stops on the discharge platform, which is convenient for the subsequent robotic arm to clamp the straightened square blank 4 and put it into the next process.

[0019] Further, such as Figure 1 As shown, baffles are provided on both sides of the chain conveyor 3 to form a channel for conveying the square embryos 4 on the chain conveyor 3. The height of the baffles should be no less than half of the height of the square embryos 4 when they are placed flat to ensure that the square embryos 4 do not fall outside the chain conveyor 3.

[0020] Further, such as Figure 1 and Figure 2 As shown, a stopper 5 is provided at the end of the chain conveyor 3. Since the square blank 4 is transferred to the chain conveyor 3 via a sloped roller conveyor, the square blank 4 has a large mass when sliding down, so the inertia is large. The setting of the stopper 5 can block the square blank 4 at the horizontal push position.

[0021] Further, such as Figure 1As shown, a baffle 6 is provided on one side of the feed position. When the push cylinder 11 pushes the square embryo 4 to the feed position, the baffle 6 limits the square embryo 4 to the feed position, so that the square embryo 4 is aligned with the feed port of the heating furnace.

[0022] Further, such as Figures 1 to 3 As shown, a pad 7 for supporting the square embryo 4 is provided on the feeding position. The upper surface of the pad 7 should be slightly higher than the lower edge of the feeding port of the heating furnace so that the square embryo 4 can be smoothly pushed into the heating furnace.

[0023] Further, such as Figure 1 As shown, the pushing mechanism 1, the detecting mechanism 2 and the chain conveyor 3 are all fixed on the same base, and the base must be able to bear the horizontal pushing feeding structure of the square blank heating furnace and the pressure of no less than three square blanks 4.

[0024] In a preferred embodiment, the stopper 5 is made of wood, because wood has high strength and good toughness, can well block the square embryo 4, and will not cause the square embryo 4 to deform. At the same time, wood is less expensive.

[0025] In summary, the present invention uses a detection device to transmit a signal that the embryo is in position to a controller, and then uses the controller to control the operation of the cylinder to achieve the change in the direction of the embryo from tilted transmission to straight placement, which provides convenience for the lower work and saves manpower.

[0026] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
