Cooling device for a suspension heat treatment conveyor line

Abstract

This utility model relates to the field of suspended heat treatment conveyor technology and discloses a cooling device for a suspended heat treatment conveyor, including a base and hooks for suspension. A cooling box is fixedly installed on the top of the base. This cooling device for a suspended heat treatment conveyor, through the setting of a control component, allows the output shaft of the motor to drive the threaded rod to rotate within the fixed frame. The moving plate can drive the fixed plate and hooks into the cooling box through the support plate and support rod. When the support block at the top of the support plate abuts against the surface of the fixed block, the support block can be moved downward under force. The fixed plate connected to the support plate surface through the support rod can drive the hook to move longitudinally. Since there are multiple sets of fixed blocks, the support blocks can abut against each other multiple times, so that the fixed plate and hooks can move longitudinally intermittently within the cooling box, making all-round contact with the cold air in each area, avoiding the fixed cooling area and causing uneven cooling.

Description

Technical Field

[0001] This utility model relates to the technical field of suspended heat treatment conveyor lines, specifically a cooling device for suspended heat treatment conveyor lines. Background Technology

[0002] Cooling devices for suspended heat treatment conveyor lines are used to cool workpieces suspended on the conveyor line, with the aim of ensuring that the workpieces meet the required performance and quality requirements after heat treatment.

[0003] In existing cooling devices for suspended heat treatment conveyor lines, the workpiece on the hook is usually in a stationary state and is constantly in a lateral movement state when cooling the workpiece. Therefore, the cooling area is fixed and uneven cooling is very likely to occur. To address this problem, we propose a cooling device for suspended heat treatment conveyor lines. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for a suspended heat treatment conveyor line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a suspended heat treatment conveyor line, comprising a base and hooks for suspension, a cooling box fixedly installed on the top of the base, cooling fins disposed inside the cooling box, a fixing frame fixedly installed on the inner wall of the cooling box, the hooks fixedly installed on the bottom of a fixing plate, and a control component disposed within the fixing frame, the control component comprising:

[0006] A support rod, one end of which is fixedly installed on the top of a fixed plate, and the other end of which is fixedly installed on the top of the support plate. A support block is fixedly installed on the top of the support plate.

[0007] The cooling component is used to cool the workpiece from all directions, so that the fixing plate and hook can move intermittently longitudinally in the cooling box, making full contact with the cold air in each area, avoiding the fixed cooling area and uneven cooling.

[0008] Preferably, the cooling component includes a spring, one end of which is fixedly installed on the top of the support plate, and the other end of which is fixedly installed on the inner wall of the movable plate. When the support plate is no longer under force, it can spring up under the action of the spring.

[0009] Preferably, the support plate passes through the movable plate and is slidably connected to the movable plate. The movable plate is in contact with the inner wall of the fixed frame. When the movable plate is subjected to force, it can slide along the inner wall of the fixed frame.

[0010] Preferably, a motor is fixedly installed on the side of the fixed frame, the output shaft of the motor is fixedly connected to a threaded rod, the threaded rod passes through the fixed frame and is rotatably connected to the fixed frame, the threaded rod passes through the movable plate and is threadedly connected to the movable plate, and when the output shaft of the motor drives the threaded rod to rotate within the fixed frame, the movable plate can be subjected to force to move laterally.

[0011] Preferably, a fixing block is fixedly installed on the front of the fixing frame. The fixing block is designed to allow the support block to move longitudinally when it comes into contact with the cut surface of the support block.

[0012] Preferably, a fixing rod is fixedly installed on the back of the fixing frame. The fixing rod has an L-shaped cross-section. When the fixing rod abuts against the surface of the movable block, the movable block can be folded.

[0013] Preferably, the side of the movable plate is hinged to the movable block, the side of the movable block is fixedly connected to one side of the torsion spring, and the other side of the torsion spring is fixedly installed on the side of the movable plate. When the movable block is no longer resisted, it can spring up from the side of the movable plate under the action of the torsion spring.

[0014] Compared with the prior art, this utility model provides a cooling device for a suspended heat treatment conveyor line, which has the following advantages:

[0015] 1. The cooling device for this suspended heat treatment conveyor line is equipped with a control component. When the output shaft of the motor drives the threaded rod to rotate within the fixed frame, the moving plate can drive the fixed plate and hook into the cooling box through the support plate and support rod. When the support block at the top of the support plate abuts against the surface of the fixed block, the support block can move downward under force. The fixed plate connected to the support rod through the surface of the support plate can drive the hook to move longitudinally. Since there are multiple sets of fixed blocks, the support blocks can abut against each other multiple times, so that the fixed plate and hook can move longitudinally intermittently within the cooling box, making full contact with the cold air in each area and avoiding the fixed cooling area, which would cause uneven cooling.

[0016] 2. The cooling device for this suspended heat treatment conveyor line is equipped with cooling components. When the output shaft of the motor drives the threaded rod to rotate, the moving plate moves along the inner wall of the fixed frame. During the movement of the moving plate, the fixing rods fixed to the side of the fixed frame will abut against the surface of the movable block. When the movable block is abutted, it can be folded under the action of the torsion spring. Similarly, there are multiple sets of fixing rods, so multiple abutments can be made, thereby buffering the moving speed of the moving plate and preventing the workpiece on the hook from being incompletely cooled due to excessive moving speed.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a cooling device for a suspended heat treatment conveyor line, including a base 1 and a hook 6 for suspension. A cooling box 2 is fixedly installed on the top of the base 1. Cooling plates 3 are installed inside the cooling box 2. A fixing frame 4 is fixedly installed on the inner wall of the cooling box 2. The hook 6 is fixedly installed on the bottom of a fixing plate 5. A control component 7 is installed inside the fixing frame 4. The control component 7 includes: a support rod 71, a support plate 72, a support block 73, and a cooling component 74. When the support block 73 at the top of the support plate 72 abuts against the surface of the fixing block 745, the cut surface of the support block 73 can be abutted and move downward under force. The surface of the support plate 72 can drive the hook 6 to move longitudinally through the fixing plate 5 connected by the support rod 71. Since there are multiple sets of fixing blocks 745, the support block 73 can be abutted multiple times, so that the fixing plate 5 and the hook 6 can move longitudinally intermittently in the cooling box 2, so as to make full contact with the cold air in each area and avoid the cooling area being fixed, which would cause uneven cooling.

[0024] The cooling component 74 includes a spring 741. One end of the spring 741 is fixedly mounted on the top of the support plate 72, and the other end is fixedly mounted on the inner wall of the movable plate 742. When the support plate 72 is no longer under force, it can spring up under the action of the spring 741. The support plate 72 passes through the movable plate 742 and is slidably connected to the movable plate 742. The movable plate 742 is in contact with the inner wall of the fixed frame 4. When the movable plate 742 is under force, it can slide along the inner wall of the fixed frame 4. A motor 744 is fixedly mounted on the side of the fixed frame 4. The output shaft of the motor 744 is fixedly connected to a threaded rod 743. The threaded rod 743 passes through the fixed frame 4 and is rotatably connected to the fixed frame 4. The threaded rod 743 passes through the movable plate 742 and is threadedly connected to the movable plate 742. When the output shaft of the motor 744 drives the threaded rod 743 to rotate within the fixed frame 4, the movable plate 742 can be subjected to force and move laterally. A fixing block 745 is fixedly installed on the front of the fixed frame 4. The fixing block 745 is configured to allow the support block 73 to move longitudinally when it comes into contact with the cross-section of the support block 73. A fixing rod 746 is fixedly installed on the back of the fixed frame 4. The cross-section of the fixing rod 746 is L-shaped. When the fixing rod 746 comes into contact with the surface of the movable block 747, the movable block 747 can be folded. The side of the movable plate 742 is hinged to the movable block 747. The side of the movable block 747 is fixedly connected to one side of the torsion spring 748. The other side of the torsion spring 748 is fixedly installed on the side of the movable plate 742. When the movable block 747 is no longer in contact with the torsion spring 748, it can spring up from the side of the movable plate 742.

[0025] In this invention, during use, the workpiece is suspended on the surface of the hook 6. After suspension, the motor 744 on the side of the fixed frame 4 is started. The output shaft of the motor 744 drives the threaded rod 743 to rotate within the fixed frame 4. When the threaded rod 743 rotates, the moving plate 742 can slide along the inner wall of the fixed frame 4 under force. During the movement of the moving plate 742, the fixing rod 746 fixed to the side of the fixed frame 4 will abut against the surface of the movable block 747. When the movable block 747 is abutted, it can be folded under the action of the torsion spring 748. Similarly, multiple sets of fixing rods 746 are provided, so multiple abutments can occur, thereby buffering the moving speed of the moving plate 742, allowing the workpiece on the hook 6 to enter the cooling box 2. When using the cooling plate 3 for cooling, to avoid incomplete cooling due to excessive movement speed, when the moving plate 742 drives the fixed plate 5 and hook 6 into the cooling box 2 via the support plate 72 and the support rod 71, when the support block 73 at the top of the support plate 72 abuts against the surface of the fixed block 745, the cut surface of the support block 73 can be moved downward under force. The fixed plate 5 connected to the support plate 72 via the support rod 71 can drive the hook 6 to move longitudinally. Since there are multiple sets of fixed blocks 745, the support block 73 can be abutted multiple times, so that the fixed plate 5 and hook 6 can move longitudinally intermittently in the cooling box 2, making full contact with the cold air in each area, avoiding the fixed cooling area and causing uneven cooling.

[0026] 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.
