Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to an automatic feeding and unloading device for heat treatment equipment. Background Technology

[0002] When heat-treating metal components in a salt bath furnace, the metal components are typically automatically fed using an external moving assembly and an electric hoist. The moving assembly and electric hoist are then controlled to lower the metal components into the salt bath furnace for heating. Once heating is complete, the electric hoist lifts the heated metal components out of the furnace and, with the help of the moving assembly, transfers them to a quenching bath for quenching. Automatic unloading is possible after quenching. However, during the heat treatment process, salt residue adhering to the outer surface of the metal components falls off during the transfer from the furnace to the quenching bath, causing pollution to the working environment. Therefore, to address these issues, an automatic feeding and unloading device for heat treatment equipment is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic feeding and unloading device for heat treatment equipment includes a moving component. A sliding block of the moving component contacts a sleeve rod at its bottom. A support rod is slidably connected to the bottom inner side of the sleeve rod. A hook is fixedly connected to the bottom end of the support rod. A fixing block is fixedly connected to the bottom right side of the sleeve rod. An electric push rod is fixedly connected to the left side of the bottom inner side of the fixing block. A bracket is fixedly connected to the bottom end of the electric push rod and slidably connected to the fixing block. A rack is fixedly connected to the right end of the bracket. A gear is meshed with the outer side of the rack, and the gear is rotatably connected to the fixing block via a rotating shaft. A fixing rod is fixedly connected to the right end of the gear and contacts the fixing block. A collection box is contacted at the right end of the outer side of the fixing rod.

[0006] As a further improvement of this utility model, a fixing bolt is spirally connected to the top of the outer side of the sleeve rod, and the fixing bolt passes through the sleeve rod. The fixing bolt is spirally connected to the track slider of the moving component.

[0007] As a further improvement of this utility model, a threaded shaft is spirally connected to the top of the inner side of the support rod, and a motor is fixedly connected to the top of the threaded shaft, and the motor is fixedly connected to the sleeve rod.

[0008] As a further improvement of this utility model, control switches are provided on both the left and right sides of the top of the support rod, and the control switches are fixedly connected to the sleeve rod.

[0009] As a further improvement of this utility model, a spring is fixedly connected to the right end of the inner side of the collection box, and a locking block is fixedly connected to the other end of the spring. The locking block is slidably connected to the collection box, and the locking block is engaged with the fixing rod. A push block penetrating the collection box is fixedly connected to one end of the outer side of the locking block, and the push block is slidably connected to the collection box.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. An automatic feeding and unloading device for heat treatment equipment, comprising a threaded shaft, a support rod, an electric push rod, a rack, a gear, and a collection box, wherein during the heat treatment of metal components, after automatic feeding and heating of the metal components in a salt bath furnace, the threaded shaft is connected to the support rod by a control motor, and the heated metal components can be lifted out by a hook. Because the control switch at the top is triggered when the support rod moves upward, after the metal components are lifted out of the salt bath furnace, the external control mechanism will control the electric push rod to retract while the control motor automatically stops. At this time, the support is pulled by controlling the electric push rod to retract, which further drives the rack to mesh with the gear, thereby driving the collection box to rotate to the bottom of the heated metal components through the fixed rod. When the heated metal components are transferred to the quenching liquid pool for quenching by the moving component, the collection box can collect the fallen salt residue attached to the outside of the metal components, thereby avoiding pollution to the working environment.

[0012] 2. An automatic feeding and unloading device for heat treatment equipment, comprising a push block, a locking block, a spring, a collection box, and a fixing rod, wherein when there is a large amount of salt residue collected in the collection box, the push block pushes the locking block to compress the spring, further disengaging the locking block from the fixing rod, thereby allowing the collection box to be removed from the outside of the fixing rod, thus facilitating the cleaning of the collected salt residue.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figure 1-3 As shown, an automatic feeding and unloading device for heat treatment equipment includes a moving component 1. The bottom of the track slider of the moving component 1 contacts a sleeve rod 2. A support rod 4 is slidably connected to the bottom inner side of the sleeve rod 2. A hook 5 is fixedly connected to the bottom bottom of the support rod 4. A fixing block 9 is fixedly connected to the bottom right side of the sleeve rod 2. An electric push rod 10 is fixedly connected to the left side of the bottom inner side of the fixing block 9. A bracket 11 that is slidably connected to the bottom of the electric push rod 10 is fixedly connected to the bottom of the electric push rod 10. A rack 12 is fixedly connected to the right side of the bracket 11. A gear 13 is meshed with the outside of the rack 12, and the gear 13 is rotatably connected to the fixing block 9 through a rotating shaft. A fixing rod 14 that contacts the fixing block 9 is fixedly connected to the right side of the gear 13. A collection box 15 is contacted on the right side of the fixing rod 14.

[0021] Example 2

[0022] like Figure 2 As shown, in order to solve the problem of inconvenience in installing the loading and unloading mechanism on the moving component 1, a fixing bolt 3 is spirally connected to the top of the outer side of the sleeve rod 2, and the fixing bolt 3 passes through the sleeve rod 2. The fixing bolt 3 is spirally connected to the track slider of the moving component 1. The sleeve rod 2 in the loading and unloading mechanism is fixed on the track slider of the moving component 1 by the fixing bolt 3, which makes it convenient to install the loading and unloading mechanism on the moving component 1.

[0023] Example 3

[0024] like Figure 2 As shown, in order to solve the problem of the inconvenience of the control device to automatically load and unload metal components, the inner top of the support rod 4 is spirally connected to a threaded shaft 6, and the top of the threaded shaft 6 is fixedly connected to a motor 7. The motor 7 is fixedly connected to the sleeve rod 2. By controlling the motor 7 to drive the threaded shaft 6 to spirally connect with the support rod 4, the support rod 4 is further controlled to drive the metal components to move up and down through the hook 5, which facilitates the control device to automatically load and unload metal components.

[0025] Example 4

[0026] like Figure 2 As shown, in order to solve the problem that it is inconvenient to control the electric push rod 10 to retract at the same time as the control motor 7 stops after the metal component is lifted, control switches 8 are provided on both the left and right sides of the top of the support rod 4, and the control switches 8 are fixedly connected to the sleeve rod 2. After the control motor 7 drives the threaded shaft 6 to be screwed to the support rod 4, and further lifts the metal component by the hook 5, the control switch 8 at the top is triggered by the support rod 4, which makes it convenient to control the electric push rod 10 to retract at the same time as the control motor 7 stops.

[0027] Example 5

[0028] like Figure 1-3 As shown, to address the issue of inconvenience in removing the collection box 15 for cleaning when there is a large amount of collected salt residue, a spring 16 is fixedly connected to the right inner side of the collection box 15. A locking block 17 is fixedly connected to the other end of the spring 16, and the locking block 17 is slidably connected to the collection box 15. The locking block 17 is engaged with the fixing rod 14. A push block 18 penetrating the collection box 15 is fixedly connected to one outer end of the locking block 17, and the push block 18 is slidably connected to the collection box 15. When there is a large amount of collected salt residue, the push block 18 pushes the locking block 17 to compress the spring 16, further disengaging the locking block 17 from the fixing rod 14, making it easier to remove the collection box 15 from the outside of the fixing rod 14 for cleaning the collected salt residue.

[0029] In this embodiment, when heat-treating the metal component, the metal component is first hung on the hook 5. Then, the external control mechanism controls the motor 7 to drive the threaded shaft 6 to connect with the support rod 4. At this time, the support rod 4 will control the metal component to descend into the salt bath furnace for heating as it moves down inside the sleeve rod 2, thus achieving automatic feeding. After automatic feeding, when the metal component is heated in the salt bath furnace, the motor 7 drives the threaded shaft 6 to reverse and connect with the support rod 4. The heated metal component can then be lifted out by the hook 5. Because the control switch 8 at the top will be triggered after the support rod 4 moves up, the external control mechanism will also control the electric push rod 10 to retract automatically while controlling the motor 7 to stop automatically. At this time, the support 11 is pulled by controlling the electric push rod 10 to retract, which further drives the rack 12 to mesh with the gear 13. This drives the collection box 15 to rotate 90 degrees through the fixed rod 14 and then rotates to the bottom of the heated metal component. The moving component 1 is then controlled to move. When the heated metal component is transferred to the quenching liquid pool for quenching, the salt residue attached to the outside of the metal component can be collected by the collection box 15 to avoid pollution of the working environment. After the heated metal component is moved to the top of the quenching liquid pool, the motor 7 is controlled to rotate forward to control the support rod 4 to move down. When the control switch 8 is no longer triggered, the electric push rod 10 will extend and reset to reset the collection box 15. Then the heated metal component will be lowered into the quenching liquid pool for quenching. When the quenching is completed and the metal component is lifted out of the quenching liquid pool, the control moving component 1 moves the heat-treated metal component to the designated position, and the control device lowers the metal component to the designated position for automatic unloading. During the use of the device, when there is a lot of salt residue collected in the collection box 15, the push block 18 pushes the locking block 17 to compress the spring 16, further disengaging the locking block 17 from the fixing rod 14. The collection box 15 can then be removed from the outside of the fixing rod 14 to clean the collected salt residue.
