Technical Field

[0001] This utility model belongs to the field of billet cutting technology, and in particular relates to a billet cutting device. Background Technology

[0002] As the raw material for angle steel production, billet blanking is a key link connecting subsequent processes such as rolling and forging in the angle steel production process. Its degree of automation and operational stability directly affect the overall production efficiency and product quality.

[0003] Current mainstream billet unloading devices mostly rely on roller conveyors to transport billets, using simple cylinder-driven structures to complete the unloading action. However, they cannot unload the billets to the designated position.

[0004] The billet may shift during the cutting process, which not only increases the cost of manual adjustment, but may also cause collision damage to the billet. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a billet feeding device, which aims to solve the problem that the existing billet feeding device cannot feed the billet to the designated position and may cause collision damage to the billet.

[0006] The present invention adopts the following technical solution:

[0007] The billet unloading device includes a frame with a pair of front and rear roller conveyors on the frame. A row of fixed plates is provided on the side wall of the frame, and a rotating shaft is provided above the fixed plates. A lifting cylinder is rotatably mounted on the frame, and the drive shaft of the lifting cylinder is rotatably connected to the rotating shaft. Several L-shaped lifting plates are provided on the rotating shaft, and the lifting plates are located between adjacent rollers in the roller conveyors. A unloading mechanism is provided below the frame. The unloading mechanism includes a base frame with a rotating drum rotatably mounted on the base frame. Several straight arms are spaced apart on the rotating drum. A support plate is rotatably mounted at the front end of each straight arm. A pull rod is rotatably mounted on the base frame corresponding to the straight arm, and the end of the pull rod is rotatably connected to the tail of the support plate.

[0008] Furthermore, the frame is provided with short baffles between adjacent rollers in the roller conveyor, and the rotating shaft is provided with long baffles, with the long baffles and short baffles distributed on the left and right sides of the rollers.

[0009] Furthermore, the billet feeding device also includes a vertical frame, which is positioned directly opposite the end of the machine frame. The vertical frame has a base plate inside, a stop bar on the front, and a back plate on the back. A blocking plate is inserted between the stop bar and the back plate on the vertical frame, and the base plate supports the blocking plate. The back plate has a pair of fixing sleeves, and a pressure rod is inserted through the back of the fixing sleeve. The front end of the pressure rod has a pressure head, and the rear end is screwed with a limit nut. The rear part of the pressure head is located inside the fixing sleeve, and the pressure head presses against the blocking plate. A spring is provided on the pressure rod between the pressure head and the fixing sleeve.

[0010] Furthermore, the long baffle has an arc-shaped notch facing the roller.

[0011] Furthermore, the support plate has a support groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. This device achieves rapid and stable billet feeding through the coordinated operation of the lifting plate and the feeding mechanism. The lifting plate can quickly lift the billet from the roller conveyor, and the feeding mechanism drives the straight arm and support plate to move through the rotation of the drum, accurately placing the billet in the designated position, which greatly improves the feeding efficiency.

[0014] 2. The baffle plate in the upright frame, through the cooperation of springs, pressure rods and pressure heads, can ensure the stability of the baffle plate in the process of blocking the steel billet. The replacement of the baffle plate is convenient and helps to improve the maintenance efficiency of the device. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-2 As shown, the billet unloading device includes a frame 1, on which a pair of front and rear roller conveyors 2 are mounted. A row of fixed plates 3 is provided on the side wall of the frame 1. A rotating shaft 4 is provided above the fixed plates 3. A lifting cylinder 5 is rotatably mounted on the frame 1, and the drive shaft of the lifting cylinder 5 is rotatably connected to the rotating shaft 4. Several L-shaped lifting plates 6 are provided on the rotating shaft 4. The lifting plates 6 are located between adjacent rollers 2.1 in the roller conveyors 2. A unloading mechanism is provided below the frame 1. The unloading mechanism includes a base frame 7. A rotating drum 8 is rotatably mounted on the base frame 7. Several straight arms 9 are spaced apart on the rotating drum 8. A support plate 10 is rotatably mounted at the front end of the straight arm 9. A pull rod 11 is rotatably mounted on the base frame 7 corresponding to the straight arm. The end of the pull rod 11 is rotatably connected to the tail of the support plate 10.

[0022] As shown in the diagram, there is a gap between the front and rear roller conveyors, and there are three straight arms. The front and rear straight arms are positioned at the front and rear of the two roller conveyors, while the middle straight arm is positioned between the two roller conveyors to avoid interference with the straight arms during the material feeding process.

[0023] When using this device, the steel billet is placed on the roller conveyor, which moves the billet forward. When the billet reaches the designated position, the lifting cylinder starts working and drives the rotating shaft to rotate. The lifting plate on the rotating shaft then moves upward, lifting the billet off the roller conveyor and freeing it from the support of the roller conveyor.

[0024] Subsequently, the drum begins to rotate, causing the straight arm to rotate upwards, and the support plate rotates along with it. Because the support plate 10 has support grooves 12, it stably supports the steel billet during movement. Then, the straight arm rotates downwards in the opposite direction, and when the support plate moves to the designated unloading position, it smoothly places the steel billet, completing one unloading operation. Throughout the unloading process, the pull rod rotates with the movement of the straight arm, ensuring that the support plate remains at the appropriate angle to guarantee that the steel billet can be unloaded.

[0025] In this structure, combined Figure 1-2 The frame 1 has a short baffle 13 located between adjacent rollers in the roller conveyor 2, and the rotating shaft 4 has a long baffle 14. The long baffle 14 and the short baffle 13 are distributed on the left and right sides of the rollers. During the billet conveying process, the long baffle and the short baffle set on the left and right sides of the roller conveyor play a limiting and guiding role to prevent the billet from deviating.

[0026] In addition, the long baffle 14 has an arc-shaped notch 15 facing the roller. The arc-shaped notch on the long baffle can better adapt to the shape of the roller and play a role in avoiding the roller.

[0027] As a specific structure, such as Figure 3 The billet feeding device also includes a stand 16, which is positioned directly opposite the end of the frame 1. The stand 16 has a base plate 17 inside, a stop bar 18 on the front, and a back plate 19 on the back. A blocking plate 20 is inserted between the stop bar and the back plate on the stand 16, and the base plate 17 supports the blocking plate 20. The back plate 19 has a pair of fixing sleeves 21. A pressure rod 22 is inserted through the back of the fixing sleeve 21. The front end of the pressure rod 22 has a pressure head 23, and the rear end is screwed with a limit nut 24. The rear part of the pressure head 23 is located inside the fixing sleeve 21, and the pressure head 23 presses against the blocking plate. A spring 25 is provided on the pressure rod between the pressure head and the fixing sleeve.

[0028] When the billet is conveyed from the roller conveyor to the upright, the baffle plate acts as a stop and positioner to prevent the billet from moving forward. Under the elastic force of the spring, the pressure head can always keep the baffle plate firmly pressed down, ensuring the stability of the baffle plate in the process of stopping the billet, preventing the baffle plate from shifting due to the impact of the billet, and reducing the possibility of damage to the baffle plate.

[0029] Meanwhile, when it is necessary to replace the baffle plate, simply pull the pressure rod backward to move the pressure head away from the baffle plate, and the baffle plate can be removed from the stand. The operation is convenient and helps to improve the maintenance efficiency of the device.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
