Description

Technical Field

[0001] The utility model relates to the technical field of metal ring processing, in particular to a metal ring processing shaping tool. Background Art

[0002] The sealing ring is a component of an electric motor, which is widely used in mechanical production and life. A metal ring is provided on the outer circumference of the sealing ring. There are many structural types of metal rings, including ordinary rings and rings with grooves on the outer surface. The metal ring is made of rolled strip metal material. Due to the increase in market demand for metal rings, mass production is required.

[0003] When processing the metal ring, the existing processing method is to clamp the metal ring with a machine tool for turning. Due to the structure of the metal ring itself and the characteristics of the material, the metal ring has a certain elasticity, which makes it easy for the size of the metal ring to have a certain deviation after processing, which can easily lead to unqualified products and inconvenience for users. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a metal ring processing and shaping tooling, which solves the problem that the existing processing method is to clamp the metal ring on a machine tool for turning processing. Due to the structure of the metal ring itself and the characteristics of the material, the metal ring has a certain elasticity, which makes it easy for the metal ring size to have a certain deviation after processing, which can easily lead to unqualified products and inconvenience for users.

[0005] The utility model provides the following technical solution: a metal ring processing and shaping tool, comprising a core mold body, a mold sleeve is arranged on the outer side of the bottom end of the core mold body, a plurality of guide holes are evenly arranged on the mold sleeve, guide shafts are inserted in the guide holes, a bottom slot is opened on the side of the bottom end of the core mold body, a push rod is inserted in the bottom slot, and a metal ring body is arranged in the core mold body.

[0006] Preferred technical solution 1: The core body is composed of eight identical modules.

[0007] Preferred technical solution 2: the inner wall of the mold sleeve is inclined, and the side wall of the mold core body is inclined to match the mold sleeve.

[0008] Preferred technical solution three: the guide hole is inclined to match the guide shaft, and the end of the guide shaft is in conflict with the outer side wall of the mold core body.

[0009] This solution can make the guide shaft more accurate when limiting the position against the side wall of the mold core body.

[0010] Preferred technical solution four: the push rod is in a T-shape for easy insertion into the bottom slot.

[0011] This solution enables the push rod to push and pull the mold core body more evenly when it is driven by the power provided by the external cylinder or hydraulic cylinder.

[0012] Preferred technical solution five: the outer side of the metal ring body is in conflict with the inner side wall of the mold core body.

[0013] This solution enables the mold core body to more stably clamp against the outer side of the metal ring body when being pushed or pulled by the push rod.

[0014] Compared with the prior art, the utility model provides a metal ring processing and shaping tool, which has the following beneficial effects:

[0015] (1) The utility model is provided with a mold core body, a mold sleeve, a guide shaft and a push rod, wherein the push rod can push the mold core body upward to expand and pull it downward to tighten through the cylinder connected thereto, so that the metal ring placed in the mold core body can be better limited and clamped. Compared with the clamping processing of a traditional lathe, the device can make the processed metal ring have higher dimensional accuracy and smaller deformation, improve the qualified rate, reduce the production cost, and has a wider range of applications and is more convenient for users.

[0022] See also Figure 1-4

[0023] Embodiment 1: A metal ring processing and shaping tool comprises a core mold body 1, a mold sleeve 2 is arranged on the outer side of the bottom end of the core mold body 1, a plurality of guide holes 3 are evenly arranged on the mold sleeve 2, a guide shaft 4 is inserted in the guide hole 3, a bottom slot 5 is opened on the side of the bottom end of the core mold body 1, a push rod 6 is inserted in the bottom slot 5, and a metal ring body 7 is arranged in the core mold body 1.

[0024] The core body 1 is composed of eight identical modules.

[0025] The inner wall of the mold sleeve 2 is inclined, and the side wall of the mold core body 1 is inclined to match the mold sleeve 2.

[0026] Embodiment 2: The difference between this embodiment and embodiment 1 is that the guide hole 3 is inclined to match the guide shaft 4, and the end of the guide shaft 4 is in conflict with the outer side wall of the mold core body 1.

[0027] Embodiment 3: The difference between this embodiment and embodiment 1 is that the push rod 6 is in a T-shape for easy insertion into the bottom slot 5 .

[0028] Embodiment 4: The difference between this embodiment and embodiment 1 is that, the outer side of the metal ring body 7 is in conflict with the inner side wall of the mold core body 1 .

[0029] In this embodiment, since the existing processing method is to clamp the metal ring with a machine tool for turning processing, the metal ring has a certain elasticity due to the structure of the metal ring itself and the characteristics of the material, which makes it easy for the size of the metal ring to have a certain deviation after processing, which can easily lead to unqualified products and inconvenience for users.

[0030] In summary, in a specific implementation, since the device is composed of a core body 1, a mold sleeve 2, a guide shaft 4 and a push rod 6, and the core body 1 is divided into 8 parts, and the bottom end of the push rod 6 can be connected to a cylinder or a hydraulic cylinder, and then the cylinder or the hydraulic cylinder provides power to the push rod 6, when the push rod 6 moves upward, the core body 1 will move upward and evenly separate to the surroundings under the thrust of the push rod 6 and the guidance of the mold sleeve 2 and the guide shaft 4, so that the metal ring body 7 is placed in the middle of the core body 1.

[0031] When the push rod 6 is pulled downward by the air cylinder or the hydraulic cylinder, the core body 1 moves downward and tightens inward under the pulling force of the push rod 6 and the guidance of the mold sleeve 2 and the guide shaft 4, which squeezes the inserted metal ring body 7 and holds it for a period of time, reducing the rebound of the metal ring body 7. The mold sleeve 2 limits the core body 1, thereby effectively resisting and clamping the metal ring body 7 placed in the core body 1.

[0032] Through this device, the axial force of the cylinder or hydraulic cylinder can be converted into radial force. The conical inclination angle of the core body 1 and the mold sleeve 2 can proportionally reduce the axial stroke to 7:1, that is, the push rod 6 moves 7mm, and the core body 1 is tightened inward by only 1mm, thereby achieving precise control of the radial stroke of the core body 1, thereby controlling the extrusion amount of the metal ring body 7. This device can produce metal rings of various specifications, from 3 inches to 24 inches, covering a wide range, high versatility, and reducing the number of tooling.
