Description

Technical Field

[0001] This utility model relates to the technical field of quenching furnace equipment, specifically a quenching furnace that is easy to feed. Background Technology

[0002] A quenching furnace is a furnace used to heat workpieces before quenching. Quenching involves placing the workpiece in the furnace and heating it to a quenching temperature above the critical point and holding it for a period of time. Then, the workpiece is quickly removed from the furnace and placed into a quenching liquid for quenching. The heat source of the furnace can be electricity or fuel, and the temperature can be measured by thermocouples. For furnaces using electricity or gas or liquid fuel, the temperature can be automatically controlled and regulated by instruments.

[0003] For example, patent document CN 218710662 U discloses a convenient aluminum alloy quenching furnace, which relates to the field of aluminum alloy quenching. The furnace is fixedly mounted on a placement plate, and a feed port is provided on the front side of the furnace. The placement plate is fixedly mounted on the furnace below the feed port. A motor is installed on the drive gear, and the drive gear locks the workpiece onto the transmission chain through a latch, thus facilitating the feeding of the workpiece. A driven gear is provided on the side of the furnace near the placement plate, and a drive gear is provided on the side of the furnace away from the driven gear. A transmission chain is provided between the drive gear and the driven gear. A pressure plate frame is fixedly mounted on the upper side of the transmission chain near the placement plate, and a latch is provided on the upper side of the pressure plate frame. A rope winding block installed on the device rod winds the moving rope into the rope winding groove, causing the moving rope to drive the closing cover plate to move in the feed port, thus opening and closing the feed port.

[0004] However, in actual use, due to its own structural limitations, this structure can only adopt a semi-open conveyor type quenching furnace for convenient feeding. In actual use, it is impossible to perform more stable switching and positioning of quenching workpieces for loading and unloading. At the same time, the equipment cannot perform more uniform and comprehensive heating of quenching workpieces in the furnace, which cannot meet the daily use needs. Therefore, it is urgent to design a quenching furnace that is convenient for feeding to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quenching furnace that facilitates feeding, in order to solve the problem mentioned in the background art that, due to the limitations of its own structure, the existing structure of the quenching furnace often only adopts a semi-open conveyor type for convenient feeding. In actual use, it is impossible to perform more stable switching and positioning of quenching workpieces for loading and unloading. At the same time, the equipment cannot perform more uniform and comprehensive heating of quenching workpieces in the furnace, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quenching furnace for convenient feeding, comprising a furnace body, wherein a pull-out side seat is fixedly connected to both sides of the furnace body, a pull-out plate is movably connected to the side of the pull-out side seat, a top frame is fixedly connected to the top of the furnace body, and a suction fan unit is provided on the surface of the top frame;

[0007] A limiting ring seat is fixedly connected to both ends of the furnace body. A pull-out bracket is movably connected inside the limiting ring seat, and docking seats are fixedly connected to both ends of the pull-out bracket.

[0008] Preferably, a sealing plug is provided between the two sets of docking seats, and a material support groove is provided on the surface of the pull-out bracket.

[0009] Preferably, a central plate is fixedly connected to the center of the pull-out bracket, and a sealing ring is fitted on the outer surface of the central plate.

[0010] Preferably, suction frames are fixedly connected to both sides of the bottom of the top frame, and suction mesh grooves are provided on the sides of the suction frames.

[0011] Preferably, air guide frames are provided on both sides of the suction unit, and air concentrators are fixedly connected between the air guide frames.

[0012] Preferably, a heating unit is provided on the inner wall of the pull plate, and a hot air hood is fixedly connected to the inner wall of the heating unit.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This convenient quenching furnace, through its furnace body, limiting ring seat, pull-out bracket, docking seat, sealing plug, material support groove, center plate, and sealing ring sleeve, allows for rapid switching of workpieces for loading and unloading within the furnace. In actual use, the operator first places the two sets of workpieces to be quenched into the material support grooves on both sides of the pull-out bracket. Then, the pull-out bracket is moved back and forth across both ends of the furnace body via the docking seats, allowing for rapid switching of the two sets of quenched workpieces within the furnace body. Simultaneously, the center plate between the pull-out brackets acts as a separator, and the sealing ring sleeve on the outer surface of the center plate, in conjunction with the sealing plug between the docking seats, ensures a seal at both ends of the furnace body, guaranteeing the airtightness of the quenching heating process within the furnace, demonstrating the practicality of the equipment design.

[0015] This conveniently fed quenching furnace, through its set of pull-out side seats, pull-out plates, top frame, suction fan unit, suction frame, suction mesh groove, air guide frame, air concentrator, heating unit, and hot air hood, further improves the overall performance of the equipment. During daily use, the operator can start the suction fan unit in the center of the top frame, which draws air from the suction mesh grooves on both sides of the bottom of the top frame. The air is then collected by the air guide frame and gathered at the air concentrator, providing uniform hot air heating to the surface of the quenched workpiece inside the furnace. At the same time, the pull-out plate on the side of the pull-out side seat, through the heating unit and hot air hood on the inner wall, heats the workpiece for inspection and also works with the top frame to circulate the hot airflow, greatly improving the uniformity of heating the workpiece inside the furnace and demonstrating the practicality of the equipment design.

[0025] Working Principle: During operation, the operator first places the two sets of workpieces requiring quenching into the material trays 10 on both sides of the pull-out bracket 7. Then, the pull-out bracket 7 is moved back and forth between the two ends of the furnace body 1 via the connecting seats 8. This allows for rapid loading and unloading of the two sets of quenched workpieces within the furnace body 1. Simultaneously, the center plate 11 between the pull-out brackets 7 acts as a separator. The sealing ring 12 fitted on the outer surface of the center plate 11, in conjunction with the sealing plug 9 between the connecting seats 8, ensures a seal at both ends of the furnace body 1, guaranteeing the airtightness of the quenching heating process within the furnace body 1. In daily use, the operator can start the suction fan unit 5 in the center of the top frame 4, so that it can draw air from the suction mesh grooves 14 of the suction frames 13 on both sides of the bottom of the top frame 4, and then collect the air through the guide frame 15 to the air concentrator 16, so as to uniformly heat the surface of the quenched workpiece inside the furnace body 1. At the same time, the pull plate 3 on the side of the pull seat 2 can be pulled through the heating unit 17 and the hot air hood 18 on the inner wall to heat the workpiece for inspection. At the same time, it can also cooperate with the top frame 4 to perform hot air circulation heating, which greatly improves the uniformity of the equipment heating of the workpiece inside the furnace body 1. The above is the complete working principle of this utility model.
