By adopting this technical solution, the beneficial effects of this invention are: it saves production time, reduces production costs, and produces products with higher quality, longer service life, and higher precision.

[0004] However, in the aforementioned prior art, after processing is completed, due to the high temperature inside the box-type resistance furnace, workers are prone to touching the inside of the box-type resistance furnace body when removing the workpiece, which can lead to injury. Utility Model Content

[0005] The purpose of this invention is to provide an isothermal normalizing heat treatment device, which solves the technical problem in the prior art that, after processing, due to the high temperature inside the box-type resistance furnace, workers are prone to touching the inside of the box-type resistance furnace body when removing the workpiece, resulting in injury.

[0006] To achieve the above objectives, this utility model employs an isothermal normalizing heat treatment device, comprising a movable frame, a resistance furnace body, and a placement mechanism. The placement mechanism includes a motor, a gear, a rack, a placement box, a transmission component, a connecting component, and a top arm. The resistance furnace body is mounted on the movable frame. The motor, the gear, and the placement box are respectively mounted on the resistance furnace body. The transmission component, the connecting component, and the top arm are respectively mounted on the placement box. The gear is fixedly connected to the output end of the motor. The rack is fixedly connected to the placement box and located at one end of the placement box. The connecting component is slidably connected to the transmission component and located at one end of the transmission component. The top arm is fixedly connected to the connecting component and located at one end of the connecting component.

[0007] The placement box includes a box body and two sliders. The two sliders are fixedly connected to the box body and are symmetrically arranged at one end of the box body.

[0008] The transmission component includes a wedge block, a spring, and a connecting rod. The spring is fixedly connected to the wedge block and located at one end of the wedge block, and the connecting rod is fixedly connected to the wedge block and located at one end of the wedge block.

One end of the connecting ring is fixedly connected to the top rod and is located at one end of the top rod. The other end of the connecting ring is rotatably connected to the connecting block and is located at one end of the connecting block.

[0011] This utility model discloses an isothermal normalizing heat treatment device. In practical use, the workpiece is placed in the placement box. The motor drives the gear to rotate, the gear drives the rack to move, and the rack drives the placement box to move, thereby moving the placement box into the resistance furnace body for processing. When the placement box moves into the resistance furnace body, the transmission component is squeezed by the resistance furnace body. The transmission component drives the connecting component to rotate, and the connecting frame drives the top arm to move downward. After processing, the motor drives the gear to rotate in the opposite direction, the gear drives the rack to move, and the rack drives the placement box to move out of the resistance furnace body. At this time, since the transmission component is no longer squeezed by the resistance furnace body, it moves out of the placement box, thereby driving the connecting component to rotate in the opposite direction. The connecting component drives the top arm to move upward, and the top arm pushes the workpiece out of the placement box. This method can effectively solve the problem that after processing, due to the high temperature inside the box-type resistance furnace body, workers are prone to touching the inside of the box-type resistance furnace body and getting injured when removing the workpiece.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] This utility model provides an isothermal normalizing heat treatment device, including a movable frame 101, a resistance furnace body 102, a motor 103, a gear 104, a rack 105, a box body 106, a slider 107, an inclined block 108, a spring 109, a connecting rod 110, a connecting block 111, a support rod 112, a bottom rod 113, a top rod 114, and a connecting ring 115. The aforementioned solution solves the problem that after processing, due to the high temperature inside the box-type resistance furnace body, workers are prone to touching the interior of the box-type resistance furnace body and getting injured when removing the workpiece.

[0023] In this specific embodiment, the resistance furnace body 102 is mounted on the movable frame 101. The motor 103, the gear 104, and the placement box are respectively mounted on the resistance furnace body 102. The transmission component, the connecting component, and the top arm are respectively mounted on the placement box. The gear 104 is fixedly connected to the output end of the motor 103. The rack 105 is fixedly connected to the placement box and located at one end of the placement box. The connecting component is slidably connected to the transmission component and located at one end of the transmission component. The top arm is fixedly connected to the connecting component and located at one end of the connecting component. The movable frame 101 and the resistance furnace body 102 are provided by existing technology. When a workpiece is placed in the placement box, the motor 103 drives the gear 104 to rotate, the gear 104 drives the rack 105 to move, and the rack 105 drives the placement box to move, thereby moving the placement box. The workpiece is processed inside the resistance furnace body 102. When the placement box moves into the resistance furnace body 102, the transmission component is squeezed by the resistance furnace body 102. The transmission component drives the connecting component to rotate, and the connecting frame drives the top arm to move downward. After processing, the motor 103 drives the gear 104 to rotate in the opposite direction. The gear 104 drives the rack 105 to move, and the rack 105 drives the placement box to move out of the resistance furnace body 102. At this time, since the transmission component is no longer squeezed by the resistance furnace body 102, it moves out of the placement box, thereby driving the connecting component to rotate in the opposite direction. The connecting component drives the top arm to move upward, and the top arm pushes the workpiece out of the placement box. This solves the problem that after processing, due to the high temperature inside the box-type resistance furnace body, workers are prone to touching the inside of the box-type resistance furnace body and getting injured when taking out the workpiece.

[0024] Two sliders 107 are fixedly connected to the housing 106 and are symmetrically arranged at one end of the housing 106. The two sliders 107 are mounted on the housing 106.

[0025] Secondly, the spring 109 is fixedly connected to the inclined block 108 and located at one end of the inclined block 108. The connecting rod 110 is fixedly connected to the inclined block 108 and located at one end of the inclined block 108. The inclined block 108 compresses the spring 109 and drives the connecting rod 110 to move.

[0026] Meanwhile, the connecting block 111 is rotatably connected to the connecting rod 110 and is located at one end of the connecting rod 110. The support rod 112 is rotatably connected to the connecting block 111 and is located at one end of the connecting block 111. The connecting rod 110 drives the connecting block 111 to rotate around the connecting rod 110 as a fulcrum.

[0027] In addition, the top rod 114 is slidably connected to the bottom rod 113 and is located at one end of the bottom rod 113. One end of the connecting ring 115 is fixedly connected to the top rod 114 and is located at one end of the top rod 114. The other end of the connecting ring 115 is rotatably connected to the connecting block 111 and is located at one end of the connecting block 111. The connecting block 111 drives the connecting ring 115 to move, and the connecting ring 115 drives the top rod 114 to move on the bottom rod 113.

[0028] In the isothermal normalizing heat treatment apparatus of this embodiment, during specific use, the workpiece is placed in the placement box. The motor 103 drives the gear 104 to rotate, the gear 104 drives the rack 105 to move, and the rack 105 drives the box body 106 to move on the resistance furnace body 102 via the two sliders 107, thereby moving the workpiece into the resistance furnace body 102 for processing. When the box body 106 enters the resistance furnace body 102, the inclined block 108 is squeezed and moved by the resistance furnace body 102. The inclined block 108 squeezes the spring 109 and drives the connecting rod 110 to move. The connecting rod 110 drives the connecting block 111 to rotate around the connecting rod 110 as a fulcrum. The connecting block drives the connecting ring 115 to move, and the connecting ring 115 drives the top rod 114 on the bottom rod. After the workpiece moves downwards from 113 and is processed, the motor 103 drives the gear 104 to rotate in the opposite direction. The gear 104 drives the rack 105 to move, and the rack 105 drives the housing 106 to move out of the resistance furnace body 102. At this time, since the inclined block 108 is not squeezed, the spring 109 resets the inclined block 108, so that the inclined block 108 drives the connecting block 111 to rotate in the opposite direction through the connecting rod 110. The connecting block 111 drives the connecting ring 115 to move, and the connecting ring 115 drives the top rod 114 to move upwards on the bottom rod 113. The top rod 114 pushes the workpiece out of the housing 106. This solves the problem that after processing, due to the high temperature inside the box-type resistance furnace body, workers are prone to touching the inside of the box-type resistance furnace body and getting injured when taking out the workpiece.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
