Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heating furnaces and relates to a feeding mechanism for heating furnaces. Background Technology
[0002] Feeding in heating furnaces typically involves automated feeding mechanisms to improve production efficiency and the accuracy of heat treatment. During the feeding process, heating furnaces often employ automated feeding mechanisms, such as feeders, to achieve rapid and accurate feeding of raw materials. This automated feeding method not only reduces manual intervention, lowers operational difficulty and labor intensity, but also improves feeding accuracy and production efficiency. For example, in medium-frequency forging heating furnaces, the automated control system can precisely control the heating process, including temperature and time, while the feeder is responsible for feeding the raw materials into the heating furnace on time and in the correct quantity, ensuring a seamless connection between the entire heating, heat treatment, and unloading process.
[0003] For example, CN221657897U discloses a feeding device for a forging heating furnace, comprising a base plate, an electric telescopic rod fixedly connected to the upper surface of the base plate, a fixed plate fixedly connected to the upper surface of the electric telescopic rod, a support leg fixedly connected to the upper surface of the base plate, a guide rail fixedly connected to the front surface of the support leg, and a second fixing member fixedly connected to the upper surface of the fixed plate. The side surface of the second fixing member has a first hole. With this structure, the device has a vertical lifting and tilting structure. The electric telescopic rod drives the fixed plate to rise along the guide rail. When it rises to the level of the heating furnace opening, a crank handle is rotated to move the threaded rod upwards. Under the action of the ball and the fourth fixing member, and the action of the first fixed shaft and the second fixing member, the conveying frame at one end of the threaded rod rises, allowing the material to slide towards the heating furnace under gravity and finally fall into the heating furnace.
[0004] When the above technical solution is used, although the conveyor frame at one end of the threaded rod is raised and the material slides towards the heating furnace under the action of gravity and finally falls into the heating furnace, the temperature inside the heating furnace is too high. When the heating furnace is turned on, the heat inside will form steam and escape from the furnace opening. When the feeding mechanism is above the heating furnace, the heat generated by the heating furnace will damage the feeding mechanism. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art. Due to the excessively high temperature inside the heating furnace, when the heating furnace is turned on, the heat inside will form steam that escapes from the furnace opening. When the feeding mechanism is above the heating furnace, the heat generated by the heating furnace will damage the feeding mechanism. Therefore, this utility model provides a feeding mechanism for the heating furnace.
[0006] This utility model includes a frame, a heating furnace is arranged in the inner cavity of the frame, a box cover is movably arranged on the upper part of the heating furnace, a driving component is arranged on the box cover, and a cooling component is arranged on the driving component.
[0007] The drive assembly includes a motor, a first lead screw is fixedly connected to the output shaft of the motor, the front side of the inner cavity of the box cover is threadedly connected to the first lead screw, a guide rod is slidably connected to the rear side of the inner cavity of the box cover, the two sides of the guide rod are fixedly connected to the inner wall of the frame respectively, and the left side of the first lead screw is movably connected to the inner wall of the frame through a rotating joint.
[0008] A drive gear is fixedly connected to the surface of the first lead screw, and a driven gear is meshed with the front side of the drive gear. A second lead screw is fixedly connected to the inner cavity of the driven gear, and the two sides of the second lead screw are movably connected to the inner wall of the frame through rotating pairs.
[0009] The cooling component includes a cooling ring, with fixed plates fixedly connected to its front and rear sides respectively. The inner cavity of one fixed plate is threadedly connected to a second lead screw, and the inner cavity of the other fixed plate is slidably connected to a limit rod. The two sides of the limit rod are fixedly connected to the inner cavity of the frame respectively. A spray nozzle is fixedly connected to the inner cavity of the cooling ring. A delivery pipe is fixedly connected to the front side of the cooling ring. A spray pump is connected to the lower part of the delivery pipe. A connecting pipe is fixedly connected to the rear side of the spray pump. A storage tank is connected to the front side of the connecting pipe.
[0010] The storage tank has a feed inlet at the top, and a connecting flange is fixedly connected to the surface of the feed inlet.
[0011] A limiting frame is fixedly connected to the left side of the heating furnace, and the upper part of the right side of the limiting frame is in contact with the cover.
[0012] The motor housing is fixedly connected to the frame, and an automatic feeding rack is provided on the left side of the heating furnace.
[0013] Working process or working principle: When it is necessary to feed materials into the heating furnace, the motor is started, which drives the first lead screw to rotate. The first lead screw then moves the cover to the side away from the heating furnace. When the first lead screw rotates, it drives the drive gear to rotate, which in turn drives the driven gear to rotate. When the driven gear rotates, it drives the second lead screw to rotate, which in turn drives the fixed plate to move. When the fixed plate moves, it drives the cooling ring to move to the top of the heating furnace and sprays high-pressure mist water to cool the heat emanating from the furnace opening. Then, the operator puts the material to be fed into the heating furnace into the upper part of the automatic feeding rack, which then transports the material into the heating furnace.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention can dissipate heat from the furnace opening when feeding materials into the heating furnace, thus preventing damage to the feeding rack due to high temperatures. Attached Figure Description
