Description

Technical Field

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

[0002] "Cutting" refers to the process of using tools or energy to separate or break objects under the action of force. It is widely used in many fields such as industrial manufacturing, construction, and processing.

[0003] Circular cutting equipment is a type of mechanical equipment that uses circular cutting components to cut objects.

[0004] The existing ring cutting equipment has the following shortcomings:

[0005] In the current technology, most ring cutting machines have a relatively complex structure, are difficult to manufacture, have limited load capacity, and have high overall power, resulting in low production efficiency and increased energy consumption costs. There is an urgent need to optimize the structural design to improve the practicality and economy of the equipment. Utility Model Content

[0006] This invention maximizes the overall drive efficiency, thereby solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a ring-shaped cutting device, comprising a main support, a rotary support, and a radial feed mechanism. The main support consists of a base, a linear movement mechanism, a drive mechanism, and a gravity balance system. The drive mechanism consists of a rack, a first reducer, a gear, and a first servo motor. The rack is fixed to the base with bolts. The first reducer is fixed to the linear movement mechanism. The gear is fixed to the output shaft of the first reducer and meshes with the rack. The first servo motor is installed at the input end of the first reducer. After the speed is reduced and the torque is increased by the first reducer, the gear is driven to move linearly along the rack. The direction of movement of the gear along the rack is parallel to the direction of movement of the linear movement mechanism along the base. Through the above components, the ring cutting can be more easily controlled.

[0008] Preferably, the base is fixed to the equipment site through multiple mounting holes on the bottom surface, and the linear moving mechanism is fixed to the vertical mounting surface of the base with bolts and can move linearly in the vertical direction. The base is fixed through multiple mounting holes, which enhances the overall structural stability of the equipment.

[0009] Preferably, the gravity balancing system is generally a nitrogen balancing cylinder, with one end fixed to the base and the other end fixed to the linear moving mechanism. When the linear moving mechanism moves downward, the gravity balancing system can generate upward pressure, reducing the driving torque of the drive mechanism and thus reducing the system power. The gravity balancing system can also be replaced by cylindrical springs, mold springs, hydraulic balancing cylinders, etc., depending on the actual structure, providing a variety of alternatives (such as springs and hydraulic cylinders). It can be flexibly selected according to the equipment structure and cost requirements, improving design compatibility.

[0010] Preferably, the rotary support consists of a mounting platform, a rotary bearing, a feed mechanism mounting plate, and a rotary drive. The mounting platform is fixed to the linear moving mechanism by bolts. The inner ring of the rotary bearing is fixed to the mounting platform, and the outer ring has gears. The feed mechanism mounting plate is fixed to the outer ring of the rotary bearing and can rotate with the outer ring of the rotary bearing. The inner ring of the rotary bearing is fixed to the mounting platform, and the outer ring directly drives the mounting plate to move, reducing transmission links and improving transmission efficiency and reliability.

[0011] Preferably, the slewing drive consists of a second reducer, a drive gear, and a second servo motor. The second reducer is fixed on the mounting platform, the drive gear is fixed at the output end of the second reducer and meshes with the outer ring gear of the slewing bearing, and the second servo motor is fixed at the input end of the second reducer. After the second reducer reduces speed and increases torque, it drives the drive gear to rotate, thereby driving the slewing bearing to rotate. The second servo motor, in conjunction with the second reducer, achieves high-precision speed regulation, ensuring that the rotation angle and speed of the slewing bearing are controllable.

[0012] Preferably, the radial feed mechanism consists of a feed mechanism, a third reducer, a third servo motor, a synchronous pulley pair, and a cutting assembly. The feed mechanism is fixed on a feed mechanism mounting plate, the third reducer is fixed on the feed mechanism, the third servo motor is mounted on the input end of the third reducer, and the output end of the third reducer is connected to the input end of the feed mechanism via a synchronous pulley pair. The feed mechanism is driven by the third servo motor through the third reducer and the synchronous pulley pair, thereby achieving precise movement of the cutting assembly along the radial direction of the slewing bearing.

[0013] Preferably, the cutting assembly comprises a housing, a cutting motor, a spiral bevel gear pair, and a cutting shaft. The housing is fixed to the output plate of the feed mechanism and can move radially along the slewing bearing under the action of the linear guide rail pair built into the feed mechanism. The cutting motor and the cutting shaft are respectively fixed at both ends of the housing to form a sealed structure. The pinion of the spiral bevel gear pair is mounted on the cutting motor, and the gear is mounted on the cutting shaft. The cutting motor drives the cutting shaft to rotate after speed reduction and torque amplification through the spiral bevel gear pair. The cutting motor and the cutting shaft are fixed at both ends of the housing to form a sealed structure, preventing dust and material debris from entering the interior, protecting the transmission components, and improving the durability of the equipment.

[0014] Preferably, since the spiral bevel gear pair is a right-angle transmission, the rotation direction of the cutting shaft is parallel to the movement direction of the rotary support, thereby realizing that the rotation direction of the cutting shaft is parallel to the material discharge direction in vertical production, realizing the cutting of materials, which can adapt to the continuous material discharge in vertical production scenarios, without the need for complex motion interpolation calculations (such as truss systems), simplifying the design of the control system and reducing the difficulty of debugging.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, each transmission part adopts a speed reduction and torque increase mechanism, which reduces the overall power while ensuring the output torque. By adopting a gravity balance mechanism, the load caused by gravity is further reduced, thereby maximizing the overall driving efficiency of the machine.

[0017] 2. In this utility model, due to the use of a slewing bearing, the material can be cut without affecting the continuous production of the material. Moreover, unlike common truss systems, which require complex motion interpolation calculations when performing ring processing, ring cutting can be more easily controlled.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figures 1-7This utility model provides a technical solution: a ring cutting device, including a main support 1, a rotary support 2, and a radial feed mechanism 3. The main support 1 consists of a base 11, a linear movement mechanism 12, a drive mechanism 13, and a gravity balance system 14. The drive mechanism 13 consists of a rack 131, a first reducer 132, a gear 133, and a first servo motor 134. The rack 131 is fixed to the base 11 by bolts. The first reducer 132 is fixed to the linear movement mechanism 12. The gear 133 is fixed on the output shaft of the first reducer 132 and meshes with the rack 131. The first servo motor 134 is installed at the input end of the first reducer 132. After the speed is reduced and the torque is increased by the first reducer 132, the gear 133 is driven to move linearly along the rack 131. The direction of movement of the gear 133 along the rack 131 is parallel to the direction of movement of the linear movement mechanism 12 along the base 11. Through the above components, the motion control of the ring cutting can be made simpler.

[0029] like Figure 2 As shown, the base 11 is fixed to the equipment site through multiple mounting holes on the bottom surface. The linear moving mechanism 12 is fixed to the vertical mounting surface of the base 11 by bolts and can move linearly in the vertical direction. The base 11 is fixed through multiple mounting holes to enhance the overall structural stability of the equipment.

[0030] like Figure 2 As shown, the gravity balancing system 14 is generally a nitrogen balancing cylinder, with one end fixed to the base 11 and the other end fixed to the linear moving mechanism 12. When the linear moving mechanism 12 moves downward, the gravity balancing system 14 can generate upward pressure, reducing the driving torque of the drive mechanism 13, thereby reducing the system power. The gravity balancing system 14 can also be replaced by cylindrical springs, mold springs, hydraulic balancing cylinders, etc., depending on the actual structure, providing a variety of alternatives (such as springs and hydraulic cylinders). It can be flexibly selected according to the equipment structure and cost requirements, improving design compatibility.

[0031] like Figure 3 As shown, the rotary support 2 consists of a mounting platform 21, a rotary bearing 22, a feed mechanism mounting plate 23, and a rotary drive 24. The mounting platform 21 is fixed to the linear moving mechanism 12 by bolts. The inner ring of the rotary bearing 22 is fixed to the mounting platform 21, and the outer ring has a gear 133. The feed mechanism mounting plate 23 is fixed to the outer ring of the rotary bearing 22 and can rotate with the outer ring of the rotary bearing 22. The inner ring of the rotary bearing 22 is fixed to the mounting platform 21, and the outer ring directly drives the mounting plate to move, reducing transmission links and improving transmission efficiency and reliability.

[0032] like Figure 3As shown, the rotary drive 24 consists of a second reducer 241, a drive gear 242, and a second servo motor 243. The second reducer 241 is fixed on the mounting platform 21, the drive gear 242 is fixed at the output end of the second reducer 241 and meshes with the outer ring gear of the slewing bearing 22, and the second servo motor 243 is fixed at the input end of the second reducer 241. After the second reducer 241 reduces speed and increases torque, the drive gear 242 rotates, thereby driving the slewing bearing 22 to rotate. The second servo motor 243, in conjunction with the second reducer 241, achieves high-precision speed regulation, ensuring that the rotation angle and speed of the slewing bearing 22 are controllable.

[0033] like Figure 5 As shown, the radial feed mechanism 3 consists of a feed mechanism 31, a third reducer 32, a third servo motor 33, a synchronous pulley pair 34, and a cutting assembly 35. The feed mechanism 31 is fixed on the feed mechanism mounting plate 23, the third reducer 32 is fixed on the feed mechanism 31, the third servo motor 33 is installed at the input end of the third reducer 32, and the output end of the third reducer 32 is connected to the input end of the feed mechanism 31 through the synchronous pulley pair 34. The third servo motor 33 drives the feed mechanism 31 through the third reducer 32 and the synchronous pulley pair 34, thereby realizing the precise radial movement of the cutting assembly 35 along the slewing bearing 22.

[0034] like Figure 5 and Figure 6 As shown, the cutting assembly 35 consists of a housing 351, a cutting motor 352, a bevel gear pair 353, and a cutting shaft 354. The housing 351 is fixed to the output plate of the upper feed mechanism 31 and can move radially along the slewing bearing 22 under the action of the lead screw linear guide pair built into the feed mechanism 31. The cutting motor 352 and the cutting shaft 354 are respectively fixed at both ends of the housing 351 to form a sealed structure. The pinion of the bevel gear pair 353 is mounted on the cutting motor 352, and the gear is mounted on the cutting shaft 354. The cutting motor 352 drives the cutting shaft 354 to rotate after the bevel gear pair 353 reduces speed and increases torque. The cutting motor 352 and the cutting shaft 354 are fixed at both ends of the housing 351 to form a sealed structure, preventing dust and material debris from entering the interior, protecting the transmission components, and improving the durability of the equipment.

[0035] like Figure 7 As shown, since the spiral bevel gear pair 353 is a right-angle transmission, the rotation direction of the cutting shaft 354 is parallel to the movement direction of the rotary support 2, thereby realizing that the rotation direction of the cutting shaft 354 is parallel to the material discharge direction in vertical production, realizing the cutting of materials. It can adapt to the continuous discharge of materials in vertical production scenarios, without the need for complex motion interpolation calculations (such as truss systems), simplifying the design of the control system and reducing the difficulty of debugging.

[0036] The operating method and working principle of this device are as follows: During operation, the first servo motor 134 drives the gear 133 to move linearly along the rack 131 on the base 11 via the first reducer 132, thereby driving the linear movement mechanism 12 to move vertically along the base 11. At the same time, the gravity balance system 14, such as the nitrogen balance cylinder, generates upward pressure, reducing the driving torque of the drive mechanism 13. In the rotary support 2, the second servo motor 243 drives the gear 242 via the second reducer 241, thereby reducing the speed and torque of the outer ring of the rotary support 22. The feed mechanism mounting plate 23 is rotated, and the radial feed mechanism 3 is driven by the third servo motor 33 through the third reducer 32 and the synchronous belt pulley pair 34 to drive the feed mechanism 31, so that the cutting assembly 35 moves radially along the slewing support 22. The cutting motor 352 drives the cutting shaft 354 to rotate through the spiral bevel gear pair 353 to reduce speed and increase torque. Because the spiral bevel gear pair 353 is a right-angle transmission, the rotation direction of the cutting shaft 354 is parallel to the movement direction of the slewing support 2 and parallel to the material discharge direction, thereby realizing the ring cutting of the material.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
