Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel billet processing technology, and in particular to a steel billet cutting and anti-bending material support device. Background Technology
[0002] Under conventional roller conveyor conditions, when steel billets are directly placed on the roller conveyor for flame cutting, the large thickness of the billets, uneven heating, and thermal expansion and contraction can easily lead to uneven cut surfaces. Especially towards the end of the cutting process, the remaining uncut portion is prone to local tearing or "cutting" due to stress release or thermal deformation, resulting in poor cross-sectional quality and large geometric deviations, which in turn affect subsequent rolling processes and yield. Therefore, a steel billet anti-bending support device is provided. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a billet cutting anti-bending material support device, which significantly improves the cross-sectional quality of flame cutting, making it flatter and more vertical. This reduces the amount of head and tail trimming required during subsequent rolling processes due to poor end quality, thereby increasing steel utilization, reducing production costs, meeting the process requirements of efficient and high-quality production, and overcoming the shortcomings of existing technologies.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A billet cutting anti-bending material support device includes a base plate and a hydraulic cylinder base. An installation groove is provided at the top of one end of the hydraulic cylinder base, and a rotating mechanism is installed in the installation groove. A column is fixed to the top of each of the two base plates, and a bearing seat is installed above each of the two columns. A main shaft is rotatably mounted on each of the two bearing seats via bearings. Two first cranks are symmetrically fixed to the outer wall of the main shaft. Stops are fixed to both ends of the two first cranks. A side plate is fixed to one side of the middle portion of each of the two first cranks, and a clamping mechanism is provided on the two side plates.
[0006] As a further embodiment of this utility model: the rotating mechanism includes a first hydraulic cylinder rotatably installed in the mounting groove, a fixed sleeve is fixed in the middle of the main shaft, two second cranks are fixed on the outer wall of the fixed sleeve, and the ends of the two second cranks away from the fixed sleeve are rotatably connected to one end of the first hydraulic cylinder through pins.
[0007] As a further improvement of this utility model, the two first cranks are located on both sides of the fixed sleeve.
[0008] As a further improvement of this utility model: support plates are welded to the top of both columns, and the bearing seat is connected to the support plates by bolts.
[0009] As a further embodiment of this utility model: the clamping mechanism includes a second hydraulic cylinder fixed on the side plate, and one end of the second hydraulic cylinder is connected to a clamping plate.
[0010] As a further improvement of this utility model: the two first cranks are of the same size, and the tops of the two first cranks are on the same horizontal plane.
[0011] As a further improvement of this utility model, mounting holes are provided at the four corners of the hydraulic cylinder base and the two seat plates.
[0012] The beneficial effects of this utility model are as follows:
[0013] It significantly improves the cross-sectional quality of flame cutting, making it flatter and more vertical, reducing the amount of head and tail trimming required in subsequent rolling processes due to poor end quality, thereby increasing steel utilization, reducing production costs, and meeting the process requirements of efficient and high-quality production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, referring to Figure 1-4A steel billet cutting anti-bending material support device includes a base plate 1 and a hydraulic cylinder base 5. One end of the hydraulic cylinder base 5 has an installation groove 6 at its top. A rotating mechanism is installed at the installation groove 6. The top of each of the two base plates 1 is fixed with a column 2. A bearing seat 9 is installed above each of the two columns 2. A main shaft 7 is rotatably mounted on the two bearing seats 9 through bearings. Two first cranks 8 are symmetrically fixed on the outer wall of the main shaft 7. A stop block 11 is fixed at both the front and rear ends of the two first cranks 8. A side plate 13 is fixed on one side of the middle of each of the two first cranks 8. A clamping mechanism is provided on the two side plates 13.
[0021] The rotating mechanism includes a first hydraulic cylinder 4 rotatably installed in the mounting groove 6, a fixed sleeve 10 fixed in the middle of the main shaft 7, two second cranks 3 fixed on the outer wall of the fixed sleeve 10, and the ends of the two second cranks 3 away from the fixed sleeve 10 being rotatably connected to one end of the first hydraulic cylinder 4 through pins.
[0022] The two first cranks 8 are located on both sides of the fixed sleeve 10.
[0023] Support plates 12 are welded to the top of both columns 2, and bearing seats 9 are connected to support plates 12 by bolts, which facilitates the installation and disassembly of spindle 7.
[0024] The clamping mechanism includes a second hydraulic cylinder 14 fixed on the side plate 13, and one end of the second hydraulic cylinder 14 is connected to a clamping plate 15.
[0025] The two first cranks 8 are the same size, and the tops of the two first cranks 8 are on the same horizontal plane.
[0026] The two seat plates 1 and the hydraulic cylinder base 5 are fixed to the installation position, so that the two first cranks 8 are located between two adjacent conveying rollers. When the steel billet moves above the two first cranks 8 on the conveying roller of the roller table, the first hydraulic cylinder 4 is extended and retracted by the external control switch, and then the two second cranks 3 rotate around the main shaft 7, thereby driving the main shaft 7 to rotate as a whole, and finally making the two first cranks 8 swing around the main shaft 7 at a certain angle to realize the action of lifting and lowering the steel billet.
[0027] After the billet is lifted and detached from the roller conveyor surface, the stops 11 at both ends of the two first cranks 8 limit the billet's movement. External control switches control the two second hydraulic cylinders 14 to push the two clamping plates 15 closer together, holding the billet in place and restricting its horizontal movement, further ensuring positional stability during the lifting process. At this point, the billet is firmly pressed against the upper ends of the two first cranks 8 under its own weight, forming a rigid support structure that effectively resists vibrations or forward / backward movement generated during cutting, thereby improving the stability of the cutting operation. This significantly enhances the cross-sectional quality of the flame cut, making it flatter and more vertical, reducing the amount of trimming required in subsequent rolling processes due to poor end quality, thus improving steel utilization, reducing production costs, and meeting the process requirements of efficient and high-quality production.
[0028] Example 2 is an optimization based on Example 1, specifically:
[0029] Mounting holes are provided at the four corners of the hydraulic cylinder base 5 and the two seat plates 1, and bolts are used to easily fix the hydraulic cylinder base 5 and the two seat plates 1 to the installation position through the mounting holes.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
