Description
Technical Field
[0001] The utility model discloses a frame structure of a lifting and swinging cutting machine, belonging to the technical field of wire cutting equipment. Background Art
[0002] In the field of mechanical manufacturing, especially when it comes to precision machining and high-load application environments, the integrity, strength, rigidity and stress distribution of castings are crucial. Although traditional welded structures can meet certain basic requirements, they have obvious limitations. The local high temperature generated during welding will cause thermal deformation, which will not only affect the dimensional accuracy of the components, but may also induce residual stress inside the material and increase the risk of fatigue cracks, thereby weakening the long-term stability and reliability of the equipment. These inherent defects may shorten the fatigue life of the equipment and increase the possibility of failure.
[0003] In addition, since stress concentration points are easily formed at welding joints, the welded structure performs poorly when facing impact or vibration, and has poor shock absorption ability. Traditional welding is large in size and difficult to carry and transport, and it is difficult to ensure the high precision requirements of the coaxiality of each roller mounting hole and the parallelism of the wire mesh. This is a major challenge for mechanical systems that require high consistency. Utility Model Content

[0029] The roller upper right frame 3 is located on the opposite side of the roller upper left frame 2 and is arranged on the upper right part of the roller lower frame 1. Roller mounting holes 101 are provided above the front end and the rear end of the roller upper right frame 3. A threading hole 301 is provided at the upper right corner of the right side of the roller upper right frame 3. A plurality of lifting through holes 302 are provided at the upper end of the roller upper right frame 3. The left side and the lower end of the roller upper right frame 3 are both open designs, that is, there is no solid baffle or other closed structure.
[0030] In order to transport separately and reduce weight, the upper left roller frame 2 and the upper right roller frame 3 are connected to the lower roller frame 1 by a detachable connection method. The detachable connection method allows the upper left roller frame 2 and the upper right roller frame 3 to be separated from the lower roller frame 1 when needed, which is convenient for transportation and maintenance.
[0031] In order to provide a convenient connection and disassembly method, the detachable connection method is one of a bolt connection, a snap connection, a pin connection or a spring clip connection, and the connection method allows disassembly without using tools or using only simple tools.
[0032] For standardized production, the roller lower frame 1, the roller upper left frame 2 and the roller upper right frame 3 are all rectangular frames.
[0033] In order to ensure the symmetry and integration of the frame, the roller disassembly and hoisting holes 202 of the roller upper left frame 2 are arranged in sequence and the intervals are kept consistent.
[0034] In order to adapt to different components, the radius of the sealing hole 201 of the upper left frame 2 of the roller is smaller than the first through hole 104 on the lower roller frame 1, and the sealing hole 201 and the first through hole 104 both extend in a cross shape to form casting process reinforcement ribs.

The diagonal lines in the square frame structure intersect, and a circular through hole is reserved at the center point of the intersection to meet specific functional and assembly requirements.
[0036] In order to meet specific functional and assembly requirements, a cross-shaped square frame structure is provided at the upper end of the rotary positioning installation position 103, and a circular through hole is reserved at the center position of the cross-shaped square frame structure.

Similarly, install the rollers in the roller mounting holes 101 in the roller upper right frame 3 and the roller upper left frame 2. The various through holes on the frame structure can be used to install cutting machines, lifting mechanisms, actuators and other related components according to different needs. The frame structure adopts split casting and is processed as a whole after assembly, which can ensure that the mounting holes of each roller are processed synchronously at one time, with higher coaxiality. The four roller mounting holes of the roller lower frame are processed and formed at one time, which ensures the coaxiality of each roller mounting hole and the parallelism of the wire network. The present application ensures the overall processing accuracy while reducing weight and split cabinet transportation.
[0040] In addition to adapting to the assembly of different equipment, the present application is provided with a variety of different through holes to take into account the stress distribution when the frame structure is bearing load. The present application effectively disperses the stress of the frame structure when bearing load by optimizing the shape and distribution of the through holes, thereby improving the overall stability of the system, reducing the risk of fatigue cracks, and further improving the performance of the frame structure when facing impact or vibration, and can effectively absorb and disperse the energy brought by external impact, reducing damage to the structure.
