Description

Technical Field

[0001] The invention relates to the technical field of metal heat treatment, in particular to a heat treatment furnace for metal heat treatment which is convenient for taking out parts. Background Art

[0002] Heat treatment furnace refers to an electric furnace or fuel furnace used for heat treatment of furnace charge, which is mainly used to change the internal structure and performance of metal materials to meet the required process requirements. It is an indispensable equipment in the metal heat treatment process. Through heating, insulation and cooling processes, metal materials are heat treated to change their organizational structure and performance. According to the shape, size and heat treatment requirements of metal parts, choose the appropriate furnace type. Common furnace types include box furnace, pit furnace, trolley furnace, etc. These furnace types have their own characteristics. For example, box furnace is suitable for batch heat treatment of small metal parts, and pit furnace is often used for heat treatment of long shaft parts.

[0003] The patent document with Chinese patent authorization announcement number CN221501179U discloses a heat treatment furnace for metal heat treatment, including a furnace body, a mounting plate, a storage plate, a heating rod and a first driven pulley; the interior of the furnace body is divided into two heat treatment chambers by a partition plate, so that the area of ​​each heat treatment chamber becomes smaller, and multiple workpieces can be heat treated at the same time in each heat treatment chamber, which greatly improves the heat treatment efficiency. During the heat treatment process, the storage plate is continuously rotated under the action of a rotating motor to realize a full-range heat treatment process of multiple workpieces at one time, which greatly improves the heat treatment efficiency.

[0004] When in use, the above patent achieves all-round heat treatment of the workpiece by mounting the workpiece to be heat treated on the placement plate, controlling the servo motor to work, reversing the servo motor output shaft, placing the workpiece inside the furnace body, and rotating the motor to make the placement plate rotate continuously.

[0015] Preferably, an observation window is provided on one side of the furnace body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the sealing cover needs to be opened, the first motor is started, and the first motor drives the bidirectional screw to rotate. Since the bidirectional screw is threadedly connected to the moving block, as the bidirectional screw rotates, the moving block will move up and down along the bidirectional screw. The movement of the moving block will drive the angle of the hinged rod to change, thereby driving the sealing cover to move and realize the opening of the sealing cover. When the sealing cover needs to be closed, the first motor is started in the reverse direction, and the moving block will move in the reverse direction along the bidirectional screw until it moves to the initial position, thereby completing the closing of the sealing cover. Since the sealing cover is connected to the fixed plate, when the sealing cover is opened or closed, it will drive the fixed plate and the placement plate to move, thereby facilitating the placement and removal of metal workpieces.

[0017] 2. When the sealing cover is closed, the first gear is meshed with the rack to drive the second bevel gear to rotate. Since the second bevel gear is meshed with the first bevel gear, when the first bevel gear rotates, it will drive the threaded rod in the fixed column to rotate, and the rotation of the threaded rod will drive the movable plate to move. As the movable plate moves, the movable disk and the limit column move synchronously until the abutment part at one end of the limit column is completely inserted into the insertion groove on the placement plate, thereby fixing the metal workpiece and preventing the metal workpiece from falling off the placement plate.

[0018] 3. By starting the driving component, the driving component drives the third rotating rod and the rotating disk to rotate. As the rotating disk rotates, the pin begins to enter the fixed groove of the ratchet. Due to the special tooth structure of the ratchet, the movement of the pin in the fixed groove will drive the ratchet and the fourth rotating rod connected to the ratchet to rotate a certain angle. When the pin moves to the tooth gap of the ratchet, the ratchet will stop rotating due to the loss of driving force. At this time, the rotating disk and the pin continue to rotate until the pin enters the next fixed groove of the ratchet again, and the above process is repeated. In this way, the intermittent movement of the pin in the fixed groove of the ratchet is used to achieve intermittent rotation of the placement plate, so that the metal workpiece is subjected to uniform heat treatment, which greatly improves the heat treatment efficiency.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 to 10 As shown, the present invention provides a heat treatment furnace for metal heat treatment which is convenient for taking out parts, including a furnace body 1, a sealing cover 2 is arranged at the open end of the furnace body 1, a heating rod 4 is arranged on the inner wall of the furnace body 1, a fixing plate 5 is arranged on one side of the sealing cover 2, a placement plate 6 is arranged on the top of the fixing plate 5, opening and closing components 3 for controlling the opening or closing of the sealing cover 2 are arranged on both sides of the furnace body 1, a fixing component 7 for fixing the metal workpiece is also arranged on the top of the fixing plate 5, a linkage component 8 for ensuring coordinated movement between the two is arranged between the opening and closing component 3 and the fixing component 7, and an intermittent rotating component 9 for driving the placement plate 6 to rotate intermittently is also arranged on one side of the fixing plate 5.

[0032] By operating the opening and closing component 3, the sealing cover 2 is opened, and the metal workpiece to be heat treated is placed on the placement plate 6. Subsequently, the opening and closing component 3 is operated again to close the sealing cover 2 to ensure the sealing inside the furnace body 1. When the sealing cover 2 is closed, the linkage component 8 drives the fixing component 7 to clamp and fix the metal workpiece to ensure that the workpiece will not fall off due to high temperature, vibration or rotation during the heat treatment process. Start the heating rod 4 to heat the inside of the furnace body 1 so that the workpiece gradually heats up to the predetermined heat treatment temperature. During the heating process, the intermittent rotating component 9 starts to work and drives the placement plate 6 to rotate intermittently, which helps the metal workpiece to be evenly heated in the furnace body 1 and improves the heat treatment effect. After the heat treatment is completed, the heating rod 4 is turned off, and the inside of the furnace body 1 is waited for to gradually cool down to a safe temperature. Operate the opening and closing component 3 to open the sealing cover 2. At this time, the linkage component 8 drives the fixing component 7 to release the metal workpiece, so that the treated metal workpiece can be easily removed from the placement plate 6.

[0033] See also Figures 1 to 4 As shown, the opening and closing assembly 3 includes a mounting frame 31, a bidirectional screw rod 32 and a first motor 33; the mounting frame 31 is arranged on both sides of the furnace body 1; the bidirectional screw rod 32 is vertically arranged on the inner side of the mounting frame 31; the first motor 33 is arranged on the top of the mounting frame 31, and the output end of the first motor 33 is connected to one end of the bidirectional screw rod 32, a moving block 34 is threadedly connected to the bidirectional screw rod 32, one side of the moving block 34 is hinged with a hinge rod 35, and the other end of the hinge rod 35 is hinged to one side of the sealing cover 2, a first sliding rod 36 is arranged on one side of the bidirectional screw rod 32 in the mounting frame 31, a slider 37 is slidably arranged on the first sliding rod 36, and one side of the slider 37 is connected to the moving block 34.

[0034] When the heat treatment furnace is not working, the sealing cover 2 is in a closed state, and the moving block 34 is in an initial position. When the sealing cover 2 needs to be opened, the first motor 33 is started, and the first motor 33 drives the bidirectional screw 32 to rotate. Since the bidirectional screw 32 is threadedly connected to the moving block 34, as the bidirectional screw 32 rotates, the moving block 34 will move up and down along the bidirectional screw 32. In this process, the slider 37 slides on the first slide bar 36, which plays a role in stabilizing the moving trajectory of the moving block 34. The movement of the moving block 34 will drive the angle of the hinge rod 35 to change, thereby driving the sealing cover 2 to move and realize the opening of the sealing cover 2. When the sealing cover 2 needs to be closed, the first motor 33 is started in the reverse direction, and the moving block 34 will move in the reverse direction along the bidirectional screw 32 until it moves to the initial position, thereby completing the closing of the sealing cover 2. And because the sealing cover 2 is connected to the fixed plate 5, when the sealing cover 2 is opened or closed, it will drive the fixed plate 5 and the placement plate 6 to move, thereby facilitating the placement and removal of metal workpieces.

[0035] See also Figure 4As shown, sliding seats 12 are further provided on both sides of the furnace body 1 , and sliding blocks 11 are provided on both sides of the sealing cover 2 , and the sliding blocks 11 are slidably provided in the sliding seats 12 .

[0036] When the sealing cover 2 moves, the sealing cover 2 drives the sliding block 11 to slide in the sliding seat 12, so that the sealing cover 2 can be opened and closed smoothly and reliably.

[0037] See also Figure 6 and Figure 7 As shown, the linkage assembly 8 includes a column 81 and a rack 85; the column 81 is arranged on the fixed plate 5 on one side of the placement plate 6, and a first rotating rod 82 is horizontally arranged on the column 81, a second bevel gear 83 is arranged at one end of the first rotating rod 82, and a first gear 84 is arranged at the other end of the first rotating rod 82; the rack 85 is arranged on the inner wall of the furnace body 1.

[0038] When the sealing cover 2 is closed, the fixing plate 5 will be driven to move toward the inside of the furnace body 1. The movement of the fixing plate 5 will drive the column 81 to move. When the column 81 enters the furnace body 1, the first gear 84 will mesh with the rack 85 on the inner wall of the furnace body 1. As the fixing plate 5 gradually moves, the first gear 84 gradually rotates. The rotation of the first gear 84 drives the first rotating rod 82 to rotate, and the first rotating rod 82 drives the second bevel gear 83 to rotate, thereby providing a power source for the fixing component 7.

[0039] See also Figure 5 and Figure 6 As shown, the fixing assembly 7 includes a fixing column 71; the fixing column 71 is arranged on one side of the column 81, and a threaded rod 72 is vertically arranged in the fixing column 71, and a movable plate 73 is threadedly connected to the threaded rod 72, and a movable disk 74 is rotatably arranged at the bottom of the movable plate 73, and a limiting column 75 is arranged at the bottom of the movable disk 74, and an abutment portion is arranged at one end of the limiting column 75, and a plug-in groove that can be plugged with the abutment portion is arranged on the placement plate 6, one end of the threaded rod 72 passes through one end of the column 81 and extends outward, and a first bevel gear 76 is arranged at the extended end of the threaded rod 72, and the first bevel gear 76 is meshed with the second bevel gear 83.

[0040] When the sealing cover 2 is closed, the first gear 84 is meshed with the rack 85 to drive the second bevel gear 83 to rotate. Since the second bevel gear 83 is meshed with the first bevel gear 76, when the first bevel gear 76 rotates, the threaded rod 72 in the fixed column 71 will be driven to rotate. The rotation of the threaded rod 72 drives the movable plate 73 to move. As the movable plate 73 moves, the movable plate 74 and the limiting column 75 move synchronously until the abutment at one end of the limiting column 75 is completely inserted into the plug-in slot on the placement plate 6, thereby fixing the metal workpiece and preventing the metal workpiece from falling off the placement plate 6. When the sealing cover 2 is opened, the first gear 84 will rotate in the opposite direction by meshing with the rack 85, thereby driving the second bevel gear 83 to rotate in the opposite direction. By the reverse rotation of the second bevel gear 83, the threaded rod 72 is driven to drive the movable plate 73 to move upward, thereby releasing the fixation of the metal workpiece. In addition, the length of the rack 85 is precisely designed to be a length that can drive the abutment to be fully and accurately inserted into the plug-in slot.

[0041] See also Figure 6 As shown, extension frames 77 are provided on both sides of the fixed column 71 , a second slide bar 78 is vertically provided in the extension frame 77 , an extension plate 79 is slidably provided on the second slide bar 78 , and one end of the extension plate 79 is connected to the movable plate 74 .

[0042] When the rotation of the threaded rod 72 drives the moving plate 73 to move, the moving plate 73 will slide on the second sliding rod 78 through the extension plates 79 on both sides, so that the moving plate 73 is more stable when moving.

[0043] See also Figures 8 to 10 As shown, the intermittent rotating component 9 includes a fourth rotating rod 911; the placing plate 6 is arranged on the top of the fixed plate 5 through a rotating shaft, one end of the rotating shaft passes through one end of the fixed plate 5 and extends outward, the fourth rotating rod 911 is arranged at the extended end of the rotating shaft, and a ratchet 912 is arranged at one end of the fourth rotating rod 911, and a third rotating rod 96 is arranged on one side of the fourth rotating rod 911 at the bottom of the fixed plate 5, and a rotating disk 98 is arranged at one end of the third rotating rod 96. A driving component for driving the rotating disk 98 to rotate is also provided on the third rotating rod 96, and a plug post 99 is provided at the bottom of the rotating disk 98, and a fixed groove for the plug post 99 to move is provided on the ratchet 912.

[0044] When it is necessary to drive the placement plate 6 to rotate intermittently, the driving component starts to work, driving the third rotating rod 96 and the rotating disk 98 to rotate. As the rotating disk 98 rotates, the pin 99 begins to enter the fixed groove of the ratchet 912. Due to the special tooth structure of the ratchet 912, the movement of the pin 99 in the fixed groove will drive the ratchet 912 and the fourth rotating rod 911 connected to the ratchet 912 to rotate at a certain angle. When the pin 99 moves to the tooth gap of the ratchet 912, the ratchet 912 will stop rotating due to the loss of driving force. At this time, the rotating disk 98 and the pin 99 continue to rotate until the pin 99 enters the next fixed groove of the ratchet 912 again, and the above process is repeated. In this way, the intermittent rotation of the placement plate 6 is achieved by the intermittent movement of the pin 99 in the fixed groove of the ratchet 912. Thereby, the metal workpiece is subjected to uniform heat treatment, which greatly improves the heat treatment efficiency.

[0045] See also Figures 8 to 10 As shown, the driving component includes a fixed block 91; the fixed block 91 is arranged on one side of the fixed plate 5, and a second rotating rod 92 is rotatably arranged in the fixed block 91, and a connecting plate 93 is arranged on one side of the sealing cover 2 and located on the top of the fixed plate 5, and a second motor 94 is arranged on the top of the connecting plate 93, and the output end of the second motor 94 is connected to one end of the second rotating rod 92, a first synchronous wheel 95 is arranged on the second rotating rod 92, and a second synchronous wheel 97 is arranged on the third rotating rod 96, and a synchronous belt 910 is sleeved on the first synchronous wheel 95 and the second synchronous wheel 97.

[0046] By starting the second motor 94, the output end of the second motor 94 drives the second rotating rod 92 to rotate. Since the first synchronous wheel 95 is arranged on the second rotating rod 92, the first synchronous wheel 95 will also rotate with the rotation of the second rotating rod 92. With the rotation of the first synchronous wheel 95, the synchronous belt 910 sleeved on the first synchronous wheel 95 and the second synchronous wheel 97 starts to drive, so that the second synchronous wheel 97 rotates with the transmission of the synchronous belt 910, and the rotation of the second synchronous wheel 97 drives the third rotating rod 96 to rotate, thereby achieving the effect of driving the third rotating rod 96 and the rotating disk 98 to rotate.

[0047] See also Fig.10 As shown, the side wall of the connecting plate 93 is in contact with the inner wall of the furnace body 1 .

[0048] The close contact between the connecting plate 93 and the inner wall of the furnace body 1 effectively reduces the space inside the furnace body 1 , so that the heating rod 4 can transfer heat to the inside of the furnace body 1 more efficiently, thereby accelerating the increase in the temperature inside the furnace body 1 .

[0049] See also Figure 1 As shown, an observation window 10 is provided on one side of the furnace body 1 .

[0050] The arrangement of the observation window 10 facilitates observation by operators.

[0051] When the heat treatment furnace is not working, the sealing cover 2 is in a closed state, and the moving block 34 is in an initial position. When the sealing cover 2 needs to be opened, the first motor 33 is started, and the first motor 33 drives the bidirectional screw 32 to rotate. Since the bidirectional screw 32 is threadedly connected to the moving block 34, as the bidirectional screw 32 rotates, the moving block 34 will move up and down along the bidirectional screw 32. In this process, the slider 37 slides on the first slide bar 36, which plays a role in stabilizing the moving trajectory of the moving block 34. The movement of the moving block 34 will drive the angle of the hinged rod 35 to change, thereby driving the sealing cover 2 to move and realize the opening of the sealing cover 2. When the sealing cover 2 is opened, the metal workpiece to be heat treated is placed on the placement plate 6, and the first motor 33 is started in reverse, and the moving block 34 will move in the reverse direction along the bidirectional screw 32 until it moves to the initial position, thereby completing the closing of the sealing cover 2. When the sealing cover 2 is closed, the fixed plate 5 will be driven to move inside the furnace body 1. Since the movement of the fixed plate 5 will drive the column 81 to move, when the column 81 enters the furnace body 1, the first gear 84 will mesh with the rack 85 on the inner wall of the furnace body 1. As the fixed plate 5 gradually moves, the first gear 84 gradually rotates. Through the rotation of the first gear 84, the first rotating rod 82 is driven to rotate, and the first rotating rod 82 drives the second bevel gear 83 to rotate. Since the second bevel gear 83 is engaged with the first bevel gear 76, when the first bevel gear 76 rotates, it will drive the threaded rod 72 in the fixed column 71 to rotate. The rotation of the threaded rod 72 drives the moving plate 73 to move. As the moving plate 73 moves, the moving plate 74 and the limiting column 75 move synchronously until the abutment at one end of the limiting column 75 is completely inserted into the plug-in slot on the placement plate 6, thereby fixing the metal workpiece and preventing the metal workpiece from falling off the placement plate 6. The heating rod 4 is started to heat the inside of the furnace body 1 so that the workpiece is gradually heated to a predetermined heat treatment temperature. During the heating process, the second motor 94 is started, and the output end of the second motor 94 drives the second rotating rod 92 to rotate. Since the first synchronous wheel 95 is arranged on the second rotating rod 92, the first synchronous wheel 95 will also rotate with the rotation of the second rotating rod 92. With the rotation of the first synchronous wheel 95, the synchronous belt 910 sleeved on the first synchronous wheel 95 and the second synchronous wheel 97 starts to drive, so that the second synchronous wheel 97 rotates with the transmission of the synchronous belt 910. Through the rotation of the second synchronous wheel 97, the third rotating rod 96 is driven to rotate, thereby achieving the effect of driving the third rotating rod 96 and the rotating disk 98 to rotate. With the rotation of the rotating disk 98, the plug 99 begins to enter the fixed groove of the ratchet 912. Due to the special tooth structure of the ratchet 912, the movement of the plug 99 in the fixed groove will drive the ratchet 912 and the fourth rotating rod 911 connected to the ratchet 912 to rotate at a certain angle. When the pin 99 moves to the tooth gap of the ratchet 912, the ratchet 912 will stop rotating due to the loss of driving force.At this time, the rotating disk 98 and the plug 99 continue to rotate until the plug 99 enters the next fixed groove of the ratchet 912 again, and the above process is repeated. In this way, the intermittent rotation of the placement plate 6 is achieved through the intermittent movement of the plug 99 in the fixed groove of the ratchet 912. As a result, the metal workpiece is subjected to uniform heat treatment, which greatly improves the efficiency of the heat treatment. After the heat treatment is completed, the heating rod 4 is turned off, and the inside of the furnace body 1 is gradually cooled to a safe temperature, and the first motor 33 is started to open the sealing cover 2. When the sealing cover 2 is opened, the first gear 84 will rotate in the opposite direction by meshing with the rack 85, thereby driving the second bevel gear 83 to rotate in the opposite direction. Through the reverse rotation of the second bevel gear 83, the threaded rod 72 is driven to drive the movable plate 73 to move upward, thereby releasing the fixation of the metal workpiece.

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
