Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical processing, and particularly relates to a charging and discharging device for an intermediate frequency induction sintering furnace. Background Art

[0002] The intermediate frequency induction sintering furnace is a common sintering device, which is widely used in the sintering process of metal and non-metal materials. Through the principle of induction heating, the materials are heated above the melting point, so that the particles are sintered together to form a dense block structure. The intermediate frequency induction sintering furnace has the advantages of fast heating speed, low energy consumption, and environmental friendliness, so it is widely used in industrial production.

[0003] When processing metal bars such as tungsten and molybdenum with an intermediate frequency induction sintering furnace, the traditional loading and unloading method is manual transportation, which has a high labor intensity and low production efficiency. Therefore, with the development of mechanized industrial production, a method of using mechanical transmission for loading and unloading has been proposed.

[0004] For example, the patent with the publication number of CN117516179A provides an automatic feeding machine for round steel in an intermediate frequency furnace and its feeding method. A forklift is used to place a raw material box filled with material bars inside a support frame. At this time, the first cylinders on both sides are started to extend, so that the rollers on both sides abut against the back of the support frame. As the first cylinders extend, the support frame flips through the sleeve on the outer wall of the sleeve rod. When flipping, the baffle limits the upper end of the raw material box close to the outside, which can prevent the material bars from falling when the raw material box rotates to an inclined position, so that the material bars can be poured into the inside of the outer shell, thus eliminating the need for manual feeding of the material bars into the inside of the outer shell, increasing the feeding speed and reducing the working intensity of workers.

[0005] However, the existing intermediate frequency furnace loading and unloading equipment has the following problems: when using a conveyor belt and its similar structures to convey the bars, it is difficult to accurately control the amount of materials put into the furnace per single time or unit time; it is also easy to get the bars stuck with the conveying platform, resulting in the loss of the bars and even the shutdown of the equipment.

[0006] Therefore, there is an urgent need for a charging and discharging device for an intermediate frequency induction sintering furnace that is more convenient to control the feeding amount and has a more stable production effect. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the problems existing in the existing bar loading and unloading equipment for intermediate frequency furnaces, such as difficult control of the feeding amount, high equipment failure rate, and unstable production effect. This application provides a charging and discharging device for an intermediate frequency induction sintering furnace, which loads or unloads the bar materials into or from the intermediate frequency furnace by grasping, with precise operation, and can reduce the frequency of equipment failures affected by the bar materials.

[0008] The utility model is realized through the following technical solutions:

[0009] An intermediate frequency induction sintering furnace loading and unloading device is used for the furnace body of an intermediate frequency induction sintering furnace.

[0014] Preferably, the clamping mechanism includes a manipulator and a sensor arranged at the clamping end of the manipulator. The manipulator is movably connected to the end of the Z-axis rod.

[0015] Preferably, a rotating shaft is arranged at the end of the Z-axis rod. The rotating shaft can rotate coaxially with the Z-axis rod, and one end of the rotating shaft away from the Z-axis rod is movably connected to the manipulator.

[0016] Preferably, an adjusting rod is arranged at the end of the rotating shaft close to the manipulator. One end of the adjusting rod is rotatably connected to one end of the rotating shaft, and the other end of the adjusting rod is detachably connected to the manipulator.
