Description

Technical Field

[0001] The utility model relates to the technical field of quenching devices, in particular to a novel quenching oil tank. Background Art

[0002] Quenching is a heat treatment process in which a metal material is heated to a certain temperature, held at that temperature for a period of time, and then rapidly cooled at a rate greater than the critical cooling rate, with the goal of enhancing the mechanical properties of the metal material. Currently, a new type of quenching oil tank, a roller-type, muffle-free mesh belt resistance furnace with patent number 201521112892.0, is used. Operators first place the spring in a material frame, hoist it onto the quenching oil tank using a crane, and then directly place the material frame into the quenching oil tank when the temperature is suitable. However, due to the high temperature, it is very difficult for workers to fix the hoist, resulting in low efficiency. Furthermore, the oil cannot always be placed in a completely horizontal and smooth manner when entering the oil tank. Sometimes, each surface of the spring is heated unevenly, which cannot meet the requirements of some high-demand springs, such as 50CrVA steel springs. This can cause deformation and cracking, uneven quenching hardness, and difficult to control the internal metallographic structure, seriously affecting the mechanical properties of the spring.

[0003] Therefore, the existing technology has the disadvantages of troublesome installation and hoisting, low efficiency, and low quality of produced springs. Utility Model Content

[0004] In view of the above problems, the utility model designs a new type of quenching oil tank, which has the advantages of uniform and controllable heating, enabling the spring to enter the oil horizontally, and effectively reducing the labor intensity of workers.

[0006] The material receiving platform includes a platform, and a guide plate with adjustable spacing is provided on the upper side of the platform. The guide plate can adjust the spacing according to the size of the spring. A plurality of positioning mounting holes are provided on the lower side of the platform, and a movable adjustable mounting rod is installed on one of the positioning mounting holes. Different positioning mounting holes can realize the gear adjustment of the inclination angle of the material receiving platform. According to the size and weight of the spring, the gear adjustment can realize that the spring can roll freely onto the rotating material tray.

[0007] The temperature measuring device and the material door are electrically connected through signals. When the temperature measured by the temperature measuring device reaches a preset temperature, the material door opens; when the temperature measured by the temperature measuring device is higher than the preset temperature, the material door closes.

[0008] The lifting and conveying mesh belt is provided with a spacer section to facilitate the conveying of the spring in the oil tank to the next process operating table.

[0009] A hair dryer is provided on the upper side of the third conveyor belt portion, which can quickly dry the excess quenching oil on the spring.

[0010] The upper end of the third conveyor belt portion is provided with a protective cover, which has the functions of preventing dust and fire.

[0011] The utility model arranges the lifting conveyor belt into three sections. The downward-inclined first conveyor belt section is responsible for slowly and steadily feeding the spring into the quenching tank. The horizontally arranged second conveyor belt section is responsible for controlling the time the spring stays in the quenching tank. The upward-inclined third conveyor belt section is responsible for transporting the spring to the next process.

[0012] Furthermore, a rotating material tray is provided at the upper end of the first conveyor belt portion of the lifting conveyor mesh belt, and the springs are delivered to the first conveyor belt portion through the rotating material tray, so that the springs will not be stacked together, and at the same time, it is ensured that the springs can be completely horizontally and smoothly put into the oil;

[0013] Furthermore, an inclined receiving platform is provided. By adjusting the inclination height of the guide plate and the receiving platform according to the size and weight of the springs, the springs can roll freely onto the rotating material tray, which is very economical and convenient and reduces the labor intensity of workers.

[0014] Furthermore, the temperature measuring device and the material gate are electrically connected via a signal to achieve target oil inlet temperature control and improve the quality of the produced springs.

[0015] In summary, the utility model has the advantages of uniform and controllable heating, enabling the spring to enter the oil horizontally, and effectively reducing the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
