Description

Technical Field

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

[0002] A heat treatment furnace is a general term for industrial furnaces used to process metal workpieces. Cast parts cannot be used directly and need to be heat treated to achieve the required mechanical properties. Normal heat treatment cannot be separated from heat treatment furnaces.

[0003] In order to ensure the stability of casting parts during the drying process, existing heat treatment furnaces usually fix the casting parts in a certain way. However, the overall temperature of the metal workpieces after heat treatment is high, which can easily cause burns when handling the workpieces. To address this issue, we propose a heat treatment furnace with automatic drying function. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment furnace with an automatic drying function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment furnace with automatic drying function, comprising a furnace body, a heating resistance wire provided on the inner wall of the furnace body, a fixed frame fixedly installed on the inner wall of the furnace body, the surface of the fixed frame being in contact with the surface of a placement plate, a connecting plate fixedly installed on the surface of the placement plate, and a control component provided within the connecting plate and the placement plate to facilitate the operator's handling of workpieces. The control component includes: a fixed plate, the fixed plate being in contact with the surface of the placement plate, a movable rod fixedly installed at the bottom of the fixed plate, the movable rod penetrating the placement plate and slidably connected to the placement plate, a sliding plate fixedly installed at the bottom of the movable rod, the sliding plate penetrating a fixed disc and slidably connected to the fixed disc, the fixed disc being fixedly installed on the surface of the connecting plate, the surface of the fixed disc being rotatably connected to the surface of a circular plate, and an arc hole being provided on the surface of the circular plate, thereby facilitating the operator's handling of metal parts and avoiding the safety hazards caused by the operator manually releasing the fixation.

[0006] Preferably, the control component further includes a positioning element, which includes a protrusion fixedly mounted on the surface of the slide plate. The surface of the protrusion is in contact with the inner wall of the arc hole. When the protrusion is abutted, the slide plate can move laterally within the fixed plate.

[0007] Preferably, a rotating rod is fixedly installed on the surface of the circular plate. The rotating rod is rotatably connected to the bottom of the placement plate. The rotating rod passes through a gear and is fixedly connected to the gear. When the gear is subjected to force, it can drive the rotating rod and the circular plate to rotate on the surface of the fixed disk.

[0008] Preferably, the surface of the gear meshes with the rack, a pressure plate is fixedly installed on the surface of the rack, the pressure plate is penetrated by a crossbar and slidably connected to the crossbar, the crossbar is fixedly installed on the inner wall of the support frame, the support frame is fixedly installed on the inner wall of the connecting plate, and when the pressure plate is under force, it can make stable lateral movement on the surface of the crossbar.

[0009] Preferably, a pressure rod is fixedly installed on the surface of the pressure plate. The pressure rod passes through the support frame and is slidably connected to the support frame. The pressure rod also passes through the connecting plate and is slidably connected to the connecting plate. When the pressure rod is not in contact with anything, it will move laterally within the connecting plate.

[0010] Preferably, the inner wall of the support frame is fixedly connected to one end of the spring, and the other end of the spring is fixedly mounted on the surface of the pressure rod. When the pressure rod is no longer subjected to the opposing force, it will spring up under the support of the spring.

[0011] Preferably, a movable block is fixedly installed on the side of the placement plate. The movable block passes through the fixed frame and is slidably connected to the fixed frame. The movable block is penetrated by a threaded rod and is threadedly connected to the threaded rod. The threaded rod passes through the fixed frame and is rotatably connected to the fixed frame. The surface of the threaded rod is fixedly connected to the output shaft of the motor. The motor is fixedly installed on the surface of the furnace body. When the output shaft of the motor drives the threaded rod to rotate, the movable block can drive the placement plate to move laterally.

[0012] Compared with the prior art, the present invention provides a heat treatment furnace with automatic drying function, which has the following beneficial effects:

[0013] 1. This heat treatment furnace with automatic drying function is equipped with a control component. When the pressure rod no longer touches the inner wall of the furnace, the pressure rod will cause the pressure plate to spring up under the support of the spring. The rack fixed on the surface of the pressure plate will move on the surface of the gear under force. The gear will drive the rotating rod to rotate. When the rotating rod rotates, the circular plate fixed on the surface of the rotating rod can rotate synchronously on the surface of the fixed plate. When the circular plate rotates, the arc hole opened on the surface of the circular plate will touch the surface of the protrusion. When the protrusion is touched, the sliding plate fixed on the surface of the protrusion will drive the fixed plate to move to both sides of the placement plate through the moving rod. After the fixed plate is opened, it no longer fixes the metal parts, which makes it easier for the operator to take out the metal parts and avoids the safety hazards caused by the operator manually releasing the fixation.

[0014] 2. This heat treatment furnace with automatic drying function is equipped with positioning components. The output shaft of the motor drives the threaded rod to rotate within the fixed frame. The moving block is forced to slide the placement plate inside the furnace. When the placement plate is removed from the furnace, it is convenient for operators to take out the metal parts, avoiding the safety hazards caused by manually reaching into the high-temperature furnace.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a heat treatment furnace with automatic drying function, including a furnace body 1, a heating resistance wire 2 provided on the inner wall of the furnace body 1, a fixing frame 3 fixedly installed on the inner wall of the furnace body 1, the surface of the fixing frame 3 being in contact with the surface of the placement plate 4, a connecting plate 5 fixedly installed on the surface of the placement plate 4, and a control component 6 provided inside the connecting plate 5 and the placement plate 4 to facilitate the operator to pick up the workpiece. The control component 6 includes: a fixing plate 61, the fixing plate 61 being in contact with the surface of the placement plate 4, and a moving rod 62 fixedly installed at the bottom of the fixing plate 61, the moving rod 62 passing through the placement plate 4 and slidably connected to the placement plate 4. A sliding plate 63 is fixedly installed at the bottom of the moving rod 62. The sliding plate 63 passes through the fixed plate 64 and is slidably connected to the fixed plate 64. The fixed plate 64 is fixedly installed on the surface of the connecting plate 5. The surface of the fixed plate 64 is rotatably connected to the surface of the circular plate 65. An arc hole 66 is opened on the surface of the circular plate 65. The starting motor 6711 drives the threaded rod 6710 to rotate, so that the placement plate 4 is moved out of the furnace body 1. After it is moved out, when the pressure rod 677 is no longer resisted, the two sets of fixed plates 61 no longer fix the metal parts, so that the operator can easily take the metal parts and avoid the safety hazards caused by the operator manually releasing the fixation.

[0021] The control assembly 6 also includes a positioning element 67, which includes a protrusion 671. The protrusion 671 is fixedly installed on the surface of the slide plate 63, and the surface of the protrusion 671 is in contact with the inner wall of the arc hole 66. When the protrusion 671 is abutted, the slide plate 63 can move laterally within the fixed plate 64. A rotating rod 672 is fixedly installed on the surface of the circular plate 65. The rotating rod 672 is rotatably connected to the bottom of the placement plate 4. The rotating rod 672 passes through the gear 673 and is fixedly connected to the gear 673. When the gear 673 is subjected to force, it can drive the rotating rod 672 and the circular plate 65 to rotate on the surface of the fixed plate 64. The surface of gear 673 meshes with rack 670. A pressure plate 674 is fixedly mounted on the surface of rack 670. The pressure plate 674 is penetrated by a crossbar 675 and slidably connected to the crossbar 675. The crossbar 675 is fixedly mounted on the inner wall of support frame 676, which is fixedly mounted on the inner wall of connecting plate 5. When pressure plate 674 is under force, it can move laterally on the surface of crossbar 675. A pressure rod 677 is fixedly mounted on the surface of pressure plate 674. The pressure rod 677 penetrates the support frame 676 and is slidably connected to it. The pressure rod 677 also penetrates the connecting plate 5 and is slidably connected to it. When pressure rod 677 is not under resistance, it will move laterally within connecting plate 5. One end of spring 678 is fixedly connected to the inner wall of support frame 676. The other end of spring 678 is fixedly mounted on the surface of pressure rod 677. When pressure rod 677 is no longer under resistance, it will spring up under the support of spring 678. A movable block 679 is fixedly installed on the side of the placement plate 4. The movable block 679 passes through the fixed frame 3 and is slidably connected to the fixed frame 3. The movable block 679 is passed through by a threaded rod 6710 and is threadedly connected to the threaded rod 6710. The threaded rod 6710 passes through the fixed frame 3 and is rotatably connected to the fixed frame 3. The surface of the threaded rod 6710 is fixedly connected to the output shaft of the motor 6711. The motor 6711 is fixedly installed on the surface of the furnace body 1. When the output shaft of the motor 6711 drives the threaded rod 6710 to rotate, the movable block 679 can drive the placement plate 4 to move laterally.

[0022] In this invention, when it is necessary to dry the cast parts, the motor 6711 on the surface of the furnace body 1 is started. The output shaft of the motor 6711 drives the threaded rod 6710 to rotate within the fixed frame 3. When the threaded rod 6710 rotates, the moving block 679 can move the placement plate 4 out of the furnace body 1. After it is moved out, the pressure rod 677 loses its squeezing force and springs up under the support of the spring 678. Then the fixed plate 61 moves to both sides of the placement plate 4 and is in an open state. Subsequently, the operator places the metal parts on the plate. Placed on the surface of the placement plate 4, after placement, the motor 6711 is started to drive the threaded rod 6710 to reverse, so the moving block 679 can drive the placement plate 4 and the connecting plate 5 to move into the furnace body 1. When the pressure rod 677 in the connecting plate 5 is abutted against the inner wall of the furnace body 1, the pressure rod 677 will slide within the connecting plate 5 under force. The pressure plate 674 fixed to the surface of the pressure rod 677 will move laterally on the surface of the crossbar 675 under force. When the pressure plate 674 moves, the rack 670 fixed to the surface of the pressure plate 674 can move on the surface of the gear 673. When the surface slides, the gear 673 can be driven by force to rotate the rotating rod 672. When the rotating rod 672 rotates, the circular plate 65 fixed on the surface of the rotating rod 672 can rotate synchronously on the surface of the fixed plate 64. When the circular plate 65 rotates, the arc hole 66 opened on the surface of the circular plate 65 will abut against the surface of the protrusion 671. When the protrusion 671 is abutted, the sliding plate 63 fixed on the surface of the protrusion 671 will drive the fixed plate 61 to move towards the center area of ​​the placement plate 4 through the moving rod 62. The retracted fixed plate 61 fixes the metal parts. To ensure the stability of the metal parts during drying, the machine door is closed after fixing, and the heating resistance wire 2 inside the furnace body 1 is activated to heat the metal parts. After heating, the motor 6711 is started to drive the threaded rod 6710 to rotate, so that the placement plate 4 is moved out of the furnace body 1. After it is moved out, when the pressure rod 677 is no longer pressed, the two sets of fixing plates 61 no longer fix the metal parts, which makes it easier for the operator to take the metal parts and avoids the safety hazards caused by the operator manually releasing the fixing.

[0023] 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.
