Description

Technical Field

[0001] This utility model relates to the field of trolley furnace technology, specifically a heat treatment trolley furnace. Background Technology

[0002] The bogie hearth furnace is a national standard energy-saving periodic furnace, mainly used for heat treatment in various industrial fields.

[0003] Chinese Utility Model Announcement No. CN220977081U includes a heating furnace body, with a track installed at the bottom of the furnace body and a conveyor seat mounted on the track. Both ends of one side of the conveyor seat are connected to drive hydraulic cylinders. Heating elements are installed on the inner wall of the heating furnace body. A cooling zone is installed on one side of the track. A cold water tank is installed above the cooling zone, with pumps installed on both sides inside the cold water tank. A cooling nozzle is installed in the middle of the upper part of the cooling zone, and cold air blowers are installed on both sides below the cooling nozzle. A heat recovery box is installed on the outside of the exhaust channel. This trolley furnace for heat treatment of mechanical parts, compared with existing devices, can extract liquid from the cold water tank through pumps and pipelines and transport it to the cooling nozzle. The liquid is then sprayed onto the parts through the cooling nozzle for rapid cooling. Simultaneously, the cold air blowers achieve both cooling and drying effects.

[0004] The applicant discovered some shortcomings in the use of the patent: the nozzle only sprays water on the top of the workpiece, resulting in uneven cooling of the workpiece and poor cooling effect.

[0005] Therefore, this utility model designs a heat treatment trolley furnace to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a heat treatment trolley furnace to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment trolley furnace, comprising: a trolley, a gantry frame installed on one side of the trolley, a hydraulic cylinder installed on the top of the gantry frame, a connecting frame connected to the output end of the hydraulic cylinder, a servo motor installed on the connecting frame, the output end of the servo motor fixedly installed to the top of a water cylinder, the bottom of the water cylinder fixedly installed to the top of a cooling cylinder, a plurality of L-shaped water pipes connected to the outer wall of the cooling cylinder, the lower part of the L-shaped water pipes passing through the cooling cylinder and having a plurality of nozzles installed thereon, a plurality of air coolers provided on the cooling cylinder, and the servo motor driving the water cylinder to rotate 360 ​​degrees in both directions, which can prevent the wires connected to the air coolers and the flexible hoses connected to the water cylinder from getting tangled.

[0008] Preferably, the bottom of the cooling cylinder is provided with several rollers. The cooling cylinder covers the workpiece, so that the rollers contact the top of the trolley. The rotation of the cooling cylinder can make the rollers roll on the trolley, reducing friction.

[0009] Preferably, one end of the gantry frame is provided with a vertical groove, and a lead screw is rotatably installed in the vertical groove. A sliding plate is slidably installed on the outer wall of the lead screw through a thread. A cleaning brush is provided at the bottom of the sliding plate. When the cooled workpiece is removed and the trolley returns to the trolley furnace, the lead screw can be rotated to lower the sliding plate, causing the cleaning brush to contact the top of the trolley. In this way, when the trolley moves, the cleaning brush can clean the position where the workpiece is placed on the top of the trolley.

[0010] Preferably, the cleaning brush and the slide are movably installed via Velcro, which facilitates the replacement of the cleaning brush.

[0011] Preferably, a limiting groove is provided at the other end of the gantry frame, and a limiting rod is installed in the limiting groove. One end of the slide plate and the guide rod are slidably installed. The limiting rod can limit the slide plate.

[0012] Preferably, the surface of the cooling cylinder is provided with several circular holes. The circular holes can reduce the overall weight of the cooling cylinder, and the circular holes facilitate the flow of smoke generated when water is sprayed to cool the workpiece.

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

[0014] 1. This utility model uses a hydraulic cylinder to drive the cooling cylinder to descend, placing the workpiece inside the cooling cylinder. The top nozzle is tilted downwards to spray water onto the top of the workpiece, while the lower nozzles spray water onto the sides of the workpiece, resulting in a larger spraying range. At the same time, the servo motor can drive the cooling cylinder to rotate 360 ​​degrees in both directions, making the spraying of water onto the workpiece more uniform and the cooling effect better.

[0026] Working principle: After the workpiece heat treatment is completed, the trolley 1 moves, moving the workpiece placed on the trolley 1 to directly below the cooling cylinder 7. Then, the hydraulic cylinder 3 drives the connecting frame 4 to descend, causing the cooling cylinder 7 to descend and cover the workpiece. The servo motor 5 then drives the water cylinder 6 to rotate 360 ​​degrees in both directions, causing the cooling cylinder 7 to rotate 360 ​​degrees in both directions. One side of the water cylinder 6 is connected to a water source via a flexible hose, and water is sprayed from the nozzle 9 through the L-shaped water pipe 8 to cool the workpiece. Simultaneously, the air cooler 10 blows air onto the workpiece for further cooling.
