Description

Technical Field

[0001] This utility model relates to the technical field of steel structure production tools and equipment, and in particular to a device for beveling the end face of angle steel workpieces. Background Technology

[0002] In the production of large steel structure columns, the sides of many workpieces' steel plates require reinforcement and support using small trusses. These trusses are often constructed by diagonally assembling and welding angle steel bars. Therefore, the production process necessitates cutting a large number of angle steel bars with beveled ends. During production, a long angle steel bar is first cut into short strips, and then beveled ends are cut at both ends of these strips using a cutting machine. This makes it easier to assemble and weld the beveled ends of the angle steel bars with the corresponding steel plates. However, in the actual production of angle steel bars, the angle of the beveled ends varies for different steel components; for example, some are 45 degrees, some 47 degrees, and some 60 degrees. Traditional cutting devices (usually small hand-operated cutting machines) are not ideal for different angles and have low production efficiency. Therefore, designing a more efficient and stable cutting device is essential. Utility Model Content

[0003] The purpose of this invention is to provide a device for beveling the end face of angle steel workpieces, which greatly improves the efficiency and stability of beveling angle steel workpieces by combining an existing hand-operated cutting machine with a corresponding structure.

[0004] The specific solution of this utility model is as follows: a device for beveling the end face of angle steel workpieces, comprising a worktable with several supporting feet at the bottom, a circular arc groove on the worktable, and corner scale lines on the edge of the circular arc groove; a rotating shaft is located at the center of the circular arc groove, and a rotating support plate is rotatably connected to the rotating shaft, one end of the rotating support plate being rotatably connected to the rotating shaft, and the other end of the rotating support plate extending to the circular arc groove; during operation, the end of the rotating support plate extending to the circular arc groove is secured to the circular arc groove by fastening bolts and nuts. For fixing the slot, the rotating support plate is also equipped with two sets of parallel clamping blocks. Each set of clamping blocks has a vertical insertion port in the middle for inserting angle steel workpieces. A hand-operated cutting machine is also provided on the side of the worktable opposite to the arc slot. The cutting blade of the hand-operated cutting machine is offset from the center of the arc slot. Two cutting anvils are provided below the cutting blade of the hand-operated cutting machine, with a gap between the two cutting anvils for the cutting blade to cut down. The upper end face of the clamping block is at the same height as the upper end face of the cutting anvil.

[0005] Furthermore, the rotating pallet described in this utility model is made of a steel plate that is straight in the middle and bent at 90 degrees at both ends.

[0006] Furthermore, in this invention, the two cutting anvils are arranged parallel to the plane of the cutting blade, and during operation, angle steel plates are placed on the cutting anvils.

[0007] Furthermore, the workbench in this invention is made of a circular steel plate, the center of which coincides with the center of the arc-shaped groove.

[0020] See Figure 1 , Figure 2This utility model relates to a device for beveling the end face of angle steel workpieces. It comprises a worktable 1 with several supporting feet 16 at its bottom. A circular arc groove 11 is provided on the worktable, penetrating the surface of the worktable. An angle scale line 12 is provided on the edge of the arc groove, used for adjusting the rotation angle of the rotating support plate. Furthermore, the worktable is made of a circular steel plate, the center of which coincides with the center of the arc groove. A rotating shaft 9 is located at the center of the arc groove, and a rotating support plate 10 is rotatably connected to the rotating shaft. Further, the rotating support plate is made of a steel plate that is straight in the middle and bent at 90-degree Z-shapes at both ends. One end is rotatably connected to the rotating shaft, and the other end of the rotating support plate extends to the arc-shaped slot. During operation, the end of the rotating support plate extending to the arc-shaped slot is fixed to the arc-shaped slot by fastening bolts 14 and nuts 15. The rotating support plate is also provided with two sets of parallel clamping blocks 13. Each set of clamping blocks has a vertical insertion port in the middle for inserting angle steel workpieces. A hand-operated cutting machine is also provided on the side of the worktable opposite to the arc-shaped slot. The cutting blade of the hand-operated cutting machine is offset from the center of the arc-shaped slot. Two cutting anvils 8 are provided below the cutting blade of the hand-operated cutting machine, with a gap between the two cutting anvils for the cutting blade to cut downwards. The upper end face of the clamping block is at the same height as the upper end face of the cutting anvil. Furthermore, in this utility model, the two cutting anvils are arranged parallel to the plane of the cutting blade. During operation, angle steel plates are placed on the cutting anvils. Furthermore, in this invention, a vertically arranged baffle 2 is provided at the rear of the hand-operated cutting machine to block cutting debris. Furthermore, the hand-operated cutting machine in this invention includes a retractable support 5, on which a cutting motor 3, an output shaft, a cutting blade 7, a handle 4, and a cutting cover 6 placed on the cutting blade are mounted.

[0021] The aforementioned hand-operated cutting machine is actually an existing technology, and its types and structures are relatively simple and common, so we will not go into details here.

[0022] Before use, the position of the hand-operated cutting machine should be planned in advance during installation. The placement position should be slightly off from the center of the rotating shaft. This design makes it easier for the front end of the angle steel bar to smoothly abut against the cutting board during use. In addition, the design of the rotation scale line is as follows: the vertical center is the zero angle scale line, and then the rotation angle lines are rotated to both sides.

[0023] This utility model serves as a practical tool, and its use is carried out as follows:

[0024] like Figure 3As shown, before cutting, first adjust the rotation angle of the rotating pallet as needed: loosen the nut, rotate the pallet to the required angle position according to the turning scale line, then tighten the nut to fix the rotating pallet, and then insert one side wing plate of the angle steel strip 17 into the vertical insertion hole opened in the middle of the two clamping blocks for limiting, while pushing the front end of the angle steel strip forward until the front end of the angle steel strip abuts the cutting anvil. The operator holds the angle steel strip while pressing down the hand-operated cutting machine to cut the corresponding beveled opening at the end of the angle steel strip.

[0025] The above process can also be completed by two people working together, with one person operating the hand-operated cutting machine and the other person operating the angle steel strip. This would be faster and more efficient.

[0026] Because the cutting angle and position of the hand-operated cutting machine's blade are fixed during the design phase, and the cutting anvil's position is also predetermined, the rotating tray and its angle steel strip are aligned and adjusted synchronously to maintain a straight line. Figure 3 As shown by the dotted line, as long as the initial angle of the rotating pallet is adjusted, the angle of the bevel cut of each angle steel strip will be constant. Cutting a large number of angle steel strips only requires repeating the operation.

[0027] This invention utilizes a rotating support plate with angular scale lines along the edge of a circular arc groove to quickly adjust the cutting angle of angle steel bars placed on it. This adjustment allows for precise control of the actual tilt angle, enabling operators to monitor the cutting tilt of the angle steel bar end face in real time. Each adjustment allows for a continuous and stable cutting angle for a batch of angle steel bars, enabling large-scale production with only repetitive actions, significantly improving production efficiency. As a completely independently designed and manufactured processing tool, this invention boasts low production costs, simple and flexible operation, and significant practical and promotional value.
