Description

Technical Field

[0001] This utility model belongs to the technical field of annular beveling equipment, and in particular relates to an annular beveling cutting device. Background Technology

[0002] In bridge construction in my country, connections between structures are necessary, including bolted connections and beveling welding. Plate butt joints are the most common, and the method of beveling is crucial. Linear beveling is typically done using semi-automatic beveling machines, while circular beveling is usually done manually with flame cutting. However, manual flame cutting results in poor beveling smoothness, inconsistent beveling size, high skill requirements for personnel, a large workload for repair welding and grinding, is time-consuming, and makes it difficult to guarantee the quality of the weld. This method is time-consuming and labor-intensive, produces poor beveling appearance, results in poor weld quality and a high rework rate, and cannot meet the needs and quality requirements of mass production of steel beams. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments:

[0018] refer to Figure 1-2As shown, this utility model provides a ring bevel cutting device, including: a frame 1, a motor 2 is arranged in the lower middle part of the frame 1, a reduction mechanism is arranged in the upper middle part of the frame 1, a drive wheel 3 is fixed at the output end of the motor 2, the drive wheel 3 is connected to the input end of the reduction mechanism through a first belt 4, a worktable 5 is fixed at the top of the frame 1, a support plate 6 is rotatably arranged at the center of the worktable 5, the support plate 6 is connected to the output end of the reduction mechanism through a rotating shaft 7, a workpiece 8 is detachably fixed at the top of the support plate 6, a semi-automatic cutting machine 9 is arranged on one side of the workpiece 8, and the semi-automatic cutting machine 9 is fixed on the worktable 5.

[0019] In a preferred embodiment, the reduction mechanism includes a first large disk 10, a second large disk 11, and a third large disk 12 rotatably mounted on a frame 1. A first small disk 13 and a second small disk 14 are fixed to the center of the first large disk 10 and the second large disk 11, respectively. The drive wheel 3 is connected to the first large disk 10 via a first belt 4. The first small disk 13 on the first large disk 10 is connected to the second large disk 11 via a second belt 15. The second small disk 14 on the second large disk 11 is connected to the third large disk 12 via a third belt 16. The top end of the third large disk 12 is connected to the rotating shaft 7. The diameter of the first large disk 10 is larger than the diameters of the drive wheel 3 and the first small disk 13; the diameter of the second large disk 11 is larger than the diameters of the first small disk 13 and the second small disk 14; and the diameter of the third large disk 12 is larger than the diameter of the second small disk 14. During operation, since the drive wheel 3 and the first large disc 10 are connected by the first belt 4, their linear velocities are the same. However, the diameter of the first large disc 10 is much larger than the diameter of the drive wheel 3, therefore, the angular velocity of the first large disc 10 is much smaller than the angular velocity of the drive wheel 3. Similarly, since the first small disc 13 is fixed at the center of the first large disc 10, their angular velocities are the same. However, the diameter of the first small disc 13 is much smaller than the diameter of the first large disc 10, therefore, the linear velocity of the first small disc 13 is much smaller than the linear velocity of the first large disc 10. Following this principle, the angular velocity of the third large disc 12 further decreases, thereby achieving a deceleration effect on the motor 2.

[0020] In a preferred embodiment, the height and cutting angle of the semi-automatic cutting machine 9 are both adjustable. The height of the semi-automatic cutting machine 9 can be adjusted according to the thickness of the workpiece 8, and the cutting angle can also be adjusted according to the required bevel angle of the workpiece 8. If the workpiece 8 is too thick, it can be preheated before cutting, and the speed should be adjusted promptly if damage occurs to prevent overheating.
