Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a trolley-type resistance furnace. Background Technology

[0002] Car-type resistance furnaces are typically used for processing large parts. In order to improve the physical properties of the product during the processing of large parts, the material needs to be heated to a sufficient temperature and be heated evenly during the heat treatment process.

[0003] According to a public notice of a trolley-type resistance furnace (Announcement No.: CN218994047U), in the above application, after the furnace door is closed, the external power supply of the drive motor is first turned on. The output end of the drive motor rotates, causing the left placement frame to rotate. The left placement frame causes the clamping plate to rotate, so that the other end of the clamping plate is placed on the right placement frame. Then the rotating door cover is put on, so that the pad clamps the clamping plate. Then the rotating door is fixed with screws. Then the external power supply of the hydraulic cylinder is turned on. The output end of the hydraulic cylinder pushes the clamping plate forward. The clamping plate pushes the furnace door, clamping the furnace door and the resistance furnace box.

[0004] However, in actual use, the above-mentioned equipment becomes difficult to open after the furnace door is opened due to excessive pressure from the clamping plates after the high temperature inside the furnace is generated. In view of this, we propose a trolley-type resistance furnace. Utility Model Content

[0005] The purpose of this invention is to provide a bogie-type resistance furnace to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trolley-type resistance furnace, comprising a furnace body, an installation plate inside the furnace body, an installation frame fixedly connected to the side of the furnace body, a slide rail fixedly connected to the side of the furnace body, a track formed on the upper surface of the installation plate, a transmission wheel fixedly connected to the upper surface of the installation frame, a winding device fixedly connected to the side of the installation plate, a connecting line fixedly connected to the output end of the winding device, a door fixedly connected to the end of the connecting line, a placement plate provided on the upper surface of the track, and a limit component provided on the upper surface of the placement plate, the limit component including:

[0007] The mounting component is fixedly connected to the upper surface of the placement plate. The top of the inner wall of the mounting component has a movable groove, and a spring is fixedly connected to the side of the inner wall of the mounting component.

[0008] A top block is fixedly connected to the end of a spring. A large threaded rod is fixedly connected to the top of the top block. A nut is threaded onto the outer surface of the large threaded rod. A fixing block is fixedly connected to the side of the door body.

[0009] Preferably, the size of the top block is adapted to the size of the mounting component, the top block is disposed inside the mounting component, and the side of the top block is arc-shaped, which allows the top block to better limit the door body.

[0010] Preferably, the center of the fixing block corresponds to the center of the door body, and the fixing block is located on the side of the door body near the bottom, so that the fixing block can be better installed on the side of the door body.

[0011] Preferably, the size of the large threaded rod is adapted to the size of the movable groove, and the large threaded rod is disposed inside the movable groove, which allows the large threaded rod to move inside the movable groove.

[0012] Preferably, the slide rail side is provided with an auxiliary component, the auxiliary component includes a fixing member, the fixing member is fixedly connected to the slide rail side, the bottom of the fixing member is fixedly connected to a motor, the output end of the motor is fixedly connected to a small threaded rod, the outer surface of the small threaded rod is threaded with a movable block, and the door side is fixedly connected to a limit member.

[0014] Preferably, the position of the limiting member corresponds to the position of the fixing member, and the limiting member is L-shaped.

[0015] Compared with the prior art, this utility model provides a bogie-type electric resistance furnace, which has the following beneficial effects:

[0016] 1. To prevent the door from being difficult to open after processing, the material is placed on the upper surface of the placement plate of this trolley-type resistance furnace. The moving device inside the placement plate moves the plate, placing it inside the furnace body. At this time, the winding device is activated, causing the connecting line to move and the door to move downward inside the slide rail. The bottom of the door contacts the upper surface of the placement plate, and the bottom of the door presses against the top block, causing the top block compression spring to contract. This allows the side of the top block to contact the door, and the outer surface of the side of the top block to contact the outer surface of the fixing block. The spring force pushes the top block to compress and limit the door, improving the seal between the door and the furnace body. Then, the nut is rotated so that the bottom of the nut contacts the upper surface of the mounting part, thus limiting the top block and allowing it to better compress the door.

[0017] 2. In order to make the door of this trolley-type resistance furnace easier to open, after the furnace body finishes processing the items, the winding device retracts, causing the connecting line to pull the door body upward. At the same time, the motor starts, causing the small threaded rod to rotate. This allows the movable block to move inside the L-shaped fixing part, thereby pushing the limiting part and moving the door body upward. This allows the door body to open more easily, so that the heat inside the resistance furnace body can be better dissipated, and the door body can be opened more conveniently.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a trolley-type resistance furnace, including a furnace body 1, an installation plate 2 inside the furnace body 1, an installation frame 4 fixedly connected to the side of the furnace body 1, a slide rail 9 fixedly connected to the side of the furnace body 1, a track 3 opened on the upper surface of the installation plate 2, a transmission wheel 5 fixedly connected to the upper surface of the installation frame 4, a winding device 8 fixedly connected to the side of the installation plate 2, a connecting line 6 fixedly connected to the output end of the winding device 8, a door 7 fixedly connected to the end of the connecting line 6, a placement plate 10 provided on the upper surface of the track 3, a limit component 11 provided on the upper surface of the placement plate 10, the limit component 11 including an installation part 1101, a movable groove 1102, a spring 1103, a top block 1104, a large threaded rod 1105, a nut 1106, and a fixing block 1107.

[0024] In this embodiment of the utility model, the mounting member 1101 is fixedly connected to the upper surface of the placement plate 10. A movable groove 1102 is provided at the top of the inner wall of the mounting member 1101. A spring 1103 is fixedly connected to the side of the inner wall of the mounting member 1101. A top block 1104 is fixedly connected to the end of the spring 1103. The size of the top block 1104 is adapted to the size of the mounting member 1101. The top block 1104 is disposed inside the mounting member 1101. The side of the top block 1104 is arc-shaped, which allows the top block 1104 to better limit the door 7. A large screw is fixedly connected to the top of the top block 1104. The threaded rod 1105 is adapted to the size of the movable groove 1102. The threaded rod 1105 is set inside the movable groove 1102, which allows the threaded rod 1105 to move inside the movable groove 1102. The outer surface of the threaded rod 1105 is threaded with a nut 1106. A fixing block 1107 is fixedly connected to the side of the door body 7. The center of the fixing block 1107 corresponds to the center of the door body 7. The fixing block 1107 is located on the side of the door body 7 near the bottom, which allows the fixing block 1107 to be better installed on the side of the door body 7.

[0025] Meanwhile, an auxiliary component 12 is provided on the side of the slide rail 9. The auxiliary component 12 includes a fixing member 1201, which is fixedly connected to the side of the slide rail 9. A motor 1202 is fixedly connected to the bottom of the fixing member 1201. A small threaded rod 1203 is fixedly connected to the output end of the motor 1202. A movable block 1204 is threadedly connected to the outer surface of the small threaded rod 1203. The size of the movable block 1204 is adapted to the size of the fixing member 1201. The movable block 1204 is located inside the fixing member 1201. A limiting member 1205 is fixedly connected to the side of the door body 7. The position of the limiting member 1205 is relative to the fixing member 1201. Corresponding to the position, the limiting member 1205 is set in an L-shape. After the resistance furnace body 1 finishes processing the items, the winding device 8 retracts, causing the connecting line 6 to pull the door 7 upward. At the same time, the motor 1202 starts, causing the small threaded rod 1203 to rotate. This allows the movable block 1204 to move inside the L-shaped fixing member 1201, thereby pushing the limiting member 1205 to move the door 7 upward. This allows the door 7 to open more easily, allowing the heat inside the resistance furnace body 1 to dissipate better, and also making it easier to open the door 7.

[0026] In this invention, during use, the material is placed on the upper surface of the placement plate 10, and the moving device inside the placement plate 10 moves, placing the placement plate 10 inside the resistance furnace body 1. At this time, the winding device 8 is activated, causing the connecting line 6 to move, thereby moving the door 7 downward inside the slide rail 9, so that the bottom of the door 7 contacts the upper surface of the placement plate 10. Simultaneously, the bottom of the door 7 presses against the top block 1104, causing the top block 1104 to compress the spring 1103, thus allowing the material to... The side of the top block 1104 contacts the door body 7, and the outer surface of the side of the top block 1104 contacts the outer surface of the fixing block 1107. This allows the elastic force of the spring 1103 to push the top block 1104 to compress and limit the door body 7, thus improving the sealing between the door body 7 and the resistance furnace body 1. Then, the nut 1106 is rotated so that the bottom of the nut 1106 contacts the upper surface of the mounting part 1101, thereby limiting the top block 1104 and allowing the top block 1104 to better compress the door body 7.

[0027] Furthermore, after the resistance furnace body 1 finishes processing the items, the winding device 8 retracts, causing the connecting line 6 to pull the door 7 upward. At the same time, the motor 1202 starts, causing the small threaded rod 1203 to rotate. This allows the movable block 1204 to move inside the L-shaped fixing member 1201, thereby pushing the limiting member 1205 to move the door 7 upward. This allows the door 7 to open more easily, allowing the heat inside the resistance furnace body 1 to dissipate better, and also making it easier to open the door 7.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
