DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In addition, if a detailed description of a known technology is not necessary for illustrating the features of the present invention, it will be omitted. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] See also Figure 1 — Figure 6 A cracking device for a circular ring part 3 comprises a cracking tool 1, a cracking rod 2 and a circular ring part 3, wherein the cracking tool 1 comprises a first tool 101 and a second tool 102, wherein the first tool 101 and the second tool 102 are combined to form a stepped circular ring shape, which is divided into a first step section 107, a second step section 108, a third step section 109 and a fourth step section 110. After the combination state, the inner wall of the circular ring part 3 is sleeved on the outer side of the first step section 107, and the inner side of the circular ring part 3 is symmetrically provided with an open groove 301, so that the circular ring part 3 can be quickly cracked and separated at the position of the open groove 301, and a through hole running through the entire cracking tool 1 is opened at the center position of the circle after the first tool 101 and the second tool 102 are combined, and the through hole cooperates with the cracking rod 2, so that the cracking rod 2 can slide in the through hole, and the upper end opening of the through hole is larger than the lower end opening, and is in an inverted trapezoidal shape, so that the outer diameter of the cracking tool 1 can be adjusted according to different inner diameters of the circular ring.

[0022] The upper end of the cracking tool 1 is sleeved in the circular ring part 3, and the thrust released from the cracking tool 1 to the outside is used to separate the circular ring part 3. The cracking pull rod 2 passes through the cracking tool 1, is centered and vertically installed in the cracking tool 1, and the cracking pull rod 2 is a special-shaped structure. The upper end of the cracking pull rod 2 is an inverted trapezoidal structure, which cooperates with the upper end of the through hole in the cracking pull rod 2. The lower end of the cracking pull rod 2 is a T-shaped structure to provide power connection. The middle position of the cracking pull rod 2 has a uniform shape and is installed in the cracking tool 1 and slides inside it. The lower end of the cracking tool 1, that is, the fourth step 110, is installed on the lower end of the first fixed surface 7 for supporting the cracking tool 1. A second fixed surface 7 is symmetrically installed below the first fixed surface 7. The fixed surface 8 is used to install the oil cylinder 4, and the oil cylinder 4 is the driving force of the cracking rod 2. The telescopic end of the oil cylinder 4 passes through the second fixed surface 8 and cooperates with the lower end of the cracking rod 2. When the piston rod of the oil cylinder 4 is retracted, its connecting end tightens the cracking rod 2, so that the cracking rod 2 moves downward in the cracking tool 1, thereby driving the first tool 101 and the second tool 102 to separate to both sides. The annular part 3 is symmetrically installed with a clamping auxiliary device, that is, a clamping tool 5. The side of the clamping tool 5 away from the part is installed with a clamping oil cylinder 6 that cooperates with the clamping tool 5, so as to prevent the cracked parts from splashing during the cracking process and prevent the parts from excessive deformation during the cracking process.

[0023] The first tooling 101 and the second tooling 102 are symmetrically provided with an air inlet 105 and an oil inlet 106 for internal cooling and lubrication of the tooling. An air blowing port 104 is provided on the upper end surface of the first step section 107. The air blowing port 104 is close to the edge of the first tooling 101 and the second tooling 102, so as to remove fine iron shavings produced during the cracking process, thereby further improving the cracking quality.

[0024] The fourth step section 110 is symmetrically provided with an internal oil lubrication channel 103 that runs through the first step section 107, the second step section 108, and the third step section 109. The cracking rod 2 is mainly affected by friction during sliding, so a grease channel, namely the oil lubrication channel 103, is designed thereon, and the grease is directly transported from the outside to the friction surface, thereby enabling the cracking rod 2 to slide smoothly in the through hole.

[0025] The entire action is driven by a closed hydraulic system, which is environmentally friendly and consumes little energy.

[0026] It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0027] See also Figure 1 The working principle of the utility model is as follows: first, the cracking tool 1 and the piston rod of the oil cylinder 4 are installed, and the inner side of the cracking part is symmetrically cut with an open groove 301, the first tool 101 and the second tool 102 are merged together, and the cracking part is sleeved on the outer side of the first step section 107 of the cracking tool 1, and the oil cylinder 4 is driven to make the piston rod of the oil cylinder 4 inward, and the cracking pull rod 2 in the cracking tool 1 is pulled. The cracking pull rod 2 moves downward under the drive of the oil cylinder 4, thereby driving the two cracking tools 1 to separate to both sides until the annular part 3 is gradually split apart, thereby completing the part cracking. The structure is simple, easy to operate, has good stability, convenient maintenance, low manufacturing cost, high cracking efficiency, and a closed working environment at the same time, avoiding secondary pollution and harm to personnel, solving the troubles of the staff and increasing production efficiency. The oil cylinder and the like are all general standard parts or parts known to those skilled in the art, and their structures and principles are all known to the technicians through technical manuals or conventional experimental methods.

[0028] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
