Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and in particular to a quenching device for machining high wear-resistant metal casting gear rings. Background Technology

[0002] In the field of metal processing, gear ring quenching is a key process for improving the hardness and wear resistance of gear rings, playing a vital role in ensuring the mechanical properties and service life of gear rings. Traditional gear ring quenching equipment has many limitations in structural design and operation procedures, especially in the workpiece transfer process after heating, which heavily relies on manual operation by personnel.

[0003] After the gear ring has finished heating in the heating coil, due to the lack of an automated unloading and transfer mechanism, operators have to use tools such as clamps or hooks to remove the hot gear ring from the heating area and move it above the quenching tank. They then carefully place it into the quenching tank for cooling and quenching. During this process, operators face the risk of burns from the high temperature, as the gear ring is extremely hot immediately after heating. Even with protective gear, prolonged close contact with the hot workpiece can easily cause burns. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-4 As shown, the present invention proposes a quenching device for processing high wear-resistant metal casting gear rings, which mainly consists of a mounting table 1, a high-frequency heating host 4, a heating coil 40, a workpiece placement assembly 5, an inclined ramp 10, a mounting table 2, a quenching pool 3, and an automatic feeding assembly 6. The various parts cooperate with each other to complete the quenching process of the gear ring.

[0022] First, the mounting table 1 serves as the basic support structure for the entire device. A high-frequency heating host 4 is firmly installed on one side of its top. The heating coil 40 precisely set on the high-frequency heating host 4 is used to efficiently heat the gear ring. The carefully designed descending groove 11 on the mounting table 1 provides crucial space for subsequent operations. The workpiece placement component 5 at the bottom of the descending groove 11 plays an important role in connecting the upper and lower parts.

[0023] The telescopic cylinder 50 in the workpiece placement assembly 5 is stably set at the bottom of the mounting table 1 and directly below the lowering groove 11. The telescopic rod of the telescopic cylinder 50 can smoothly pass through the mounting table 1 and extend into the lowering groove 11. The placement top plate 51 set at the top of its telescopic rod is on the same central axis as the heating coil 40, which ensures the stability and accurate positioning of the gear ring during the lifting process. The central rod 52 set at the top of the placement top plate 51 further plays a role in positioning and supporting the gear ring, preventing the gear ring from shifting during the heating process.

[0024] A pair of support handles 12 are symmetrically arranged on one side of the mounting table 1. The two support handles 12 are also symmetrically arranged on both sides of the ramp 10, which effectively fixes and supports the ramp 10.

[0025] The automatic feeding assembly 6 is a key component for realizing the automatic transfer of the gear ring from the heating zone to the quenching zone. The rotating shaft 60 is flexibly and movable between the two support shanks 12 via a pair of bearing seats 61. The slide plate 62 tightly installed on the rotating shaft 60 has baffles 63 symmetrically arranged on both sides of its top, which can effectively prevent the gear ring from sliding off the sides of the slide plate 62 during the downward movement. The connecting plates 64 symmetrically arranged on both sides of the top of the slide plate 62 form a tight connection structure with the subsequent telescopic cylinder 68.

[0026] In the automatic feeding assembly 6, a pair of first connectors 66 are firmly set on the top of the mounting table 2 and are located below the two connecting plates 64 respectively. The telescopic cylinder 68 is flexibly installed on the first connector 66. The second connector 67 on the top of its telescopic rod is movably connected to the connecting plate 64. Through the telescopic movement of the telescopic cylinder 68, the tilt angle of the slide plate 62 can be controlled, thereby realizing the automatic feeding of the gear ring.

[0027] In addition, the through groove 65 opened on the slide plate 62 is carefully designed to be wider than the diameter of the top plate 51, ensuring that the top plate 51 can pass smoothly through the through groove 65 during the lifting and lowering process without interfering with the slide plate 62. The drain valve pipe 30 set on one side of the quenching pool 3 facilitates the discharge and replacement of the liquid after quenching, ensuring the continuous operation of quenching.

[0028] In the operation process of the equipment, firstly, start the telescopic cylinder 50 to push out the telescopic rod. When the telescopic rod smoothly lifts the placement top plate 51 and ensures that the placement top plate 51 passes smoothly through the through groove 65, immediately stop the telescopic cylinder 50. At this time, the operator carefully places the toothed ring that needs to be quenched onto the placement top plate 51. During the placement process, it is necessary to ensure that the toothed ring is stable and located in the center of the placement top plate 51 to prevent positional deviation in subsequent operations.

[0029] Next, the telescopic cylinder 50 is activated again, so that it slowly and evenly lifts the gear ring upward to the inner center area of ​​the heating coil 40, ensuring that the gear ring can be completely surrounded by the heating coil 40, thereby achieving uniform heating.

[0030] Then, the high-frequency heating host 4 is started, and the gear ring is heated quickly and efficiently through the heating coil 40. During the heating process, the heating host needs to accurately control the heating power and time according to the material, size and quenching temperature of the gear ring, to ensure the uniformity and stability of the gear ring heating and avoid local overheating or underheating.

[0031] After the heating process is completed, the telescopic cylinder 50 slowly retracts the telescopic rod, and the placement top plate 51 will gradually descend as the telescopic rod retracts. When the placement top plate 51 has completely passed through the through groove 65, the heated toothed ring will stay on the slide plate 62. At this time, the toothed ring should be at the starting end of the slide plate 62 and remain stationary.

[0032] Next, the two telescopic cylinders 68 are activated simultaneously and retract their telescopic rods. Since one side of the slide plate 62 is connected to the two telescopic cylinders 68, the activation will cause the slide plate 62 to rotate around the pivot 60. Therefore, when the telescopic cylinder 68 retracts its telescopic rod, this side of the slide plate 62 will rotate downwards. During the rotation, when a pre-set specific angle is reached, the heated gear ring will slide rapidly downwards along the inclined surface of the slide plate 62 under the action of gravity, and finally fall accurately into the quenching pool 3 for rapid cooling and quenching treatment, thus completing the entire gear ring quenching process.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
