Description

Technical Field

[0001] This utility model belongs to the field of vacuum tempering furnace technology, specifically a vacuum tempering furnace with uniform heating. Background Technology

[0002] A vacuum tempering furnace is a device used for metal heat treatment. It is primarily used to temper metal parts in a vacuum environment to improve their mechanical properties. It uses a vacuum pump to remove air from the furnace, creating a low-oxygen or oxygen-free environment, reducing oxidation and contamination on the metal surface and protecting the surface quality of the parts. In traditional vacuum tempering furnaces, the items inside are often stationary, leading to uneven heating where some parts are overheated while others are underheated. This uneven heating can negatively impact the final performance of the finished product. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a vacuum tempering furnace with uniform heating, which solves the problem that in traditional vacuum tempering furnaces, the items inside are often stationary, which leads to some items being overheated and others underheated, resulting in uneven heating and easily affecting the final performance of the finished product.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a vacuum tempering furnace with uniform heating, comprising a base plate, two supports fixedly connected to the top of the base plate, a vacuum tempering furnace body fixedly connected to the top of the two supports, a cover plate provided on one side of the vacuum tempering furnace body, a motor fixedly connected to one side of the cover plate, a turntable fixedly connected to the output shaft of the motor through the cover plate, and a plurality of fixed clamping plates fixedly connected to one side of the turntable;

[0005] Several fixed plates are fixedly connected to one side of the turntable. Two movable rods are slidably connected to the fixed plates. A pull plate is fixedly connected to one end of each movable rod, and a movable clamping plate is fixedly connected to the other end of each movable rod. The movable clamping plate has an arc surface design and corresponds to the fixed clamping plate. A spring is sleeved on the movable rod.

[0006] As a further embodiment of this utility model: one end of the spring is fixedly connected to the movable clamping plate, and the other end of the spring is fixedly connected to the fixed plate.

[0007] As a further embodiment of this utility model: the vacuum tempering furnace body is provided with a number of sliding holes, which are evenly distributed on the vacuum tempering furnace body.

[0008] As a further embodiment of this utility model: a sliding rod is slidably connected inside the sliding hole, and one end of the sliding rod is fixed to the cover plate.

[0009] As a further embodiment of this utility model: the number of sliding rods is several, and the several sliding rods are evenly distributed on one side of the cover plate, and a vertical plate is fixedly connected to the top of the bottom plate.

[0010] As a further embodiment of this utility model: two electric push rods are fixedly connected to one side of the upright plate, and a connecting plate is fixedly connected to one end of each of the two electric push rods. The connecting plate is fixed to the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This uniformly heated vacuum tempering furnace, through the installation of a motor, springs, a movable clamping plate, and a fixed clamping plate, operates as follows: Activating the electric push rod moves the connecting plate, motor, cover plate, and slide rod to the right. The slide rod slides within the sliding hole, simultaneously supporting the cover plate to prevent it from falling off during sliding. The item to be heated is then placed between the fixed and movable clamping plates. When the item contacts the curved surface of the movable clamping plate, it pushes the plate away a certain distance, and the spring pressure secures the item. Activating the electric push rod then moves the connecting plate, motor, cover plate, and slide rod to the left until the item enters the vacuum tempering furnace body. Finally, activating the vacuum tempering furnace body and motor initiates the vacuum tempering process. The furnace body heats the items, and the motor drives the items to rotate, thus achieving uniform heating. After heating is complete and the items have cooled down, the electric push rod is activated, which moves the connecting plate, motor, cover plate, and slide rod to the right, allowing the items to be sent out of the vacuum reheating furnace body. At this time, pulling the pull plate moves the movable rod and the movable clamping plate away from the items, allowing the items to be removed. The reheating furnace uses spring pressure to fix the items, improving their stability. Moreover, it can rotate the items while heating them, allowing them to receive heat evenly from different angles and directions, thereby reducing the problem of local overheating or underheating. It can achieve uniform heating and improve the final performance of the finished product.

[0013] 2. This uniformly heated vacuum tempering furnace, through the installation of a sliding rod, sliding hole, and electric push rod, allows for the following operation: After the item is fixed, the electric push rod is activated, moving the connecting plate, motor, cover plate, and sliding rod to the left, feeding the item into the furnace body. The furnace body and motor then heat the item. After heating and cooling, the electric push rod is activated again, moving the connecting plate, motor, cover plate, and sliding rod to the right, feeding the item out of the furnace body. The electric push rod enables the cover plate and item to move left and right to feed and remove the item, facilitating loading and unloading. Furthermore, the sliding rod, within the sliding hole, supports the cover plate during movement, preventing it from falling and improving stability. The sliding rod also guides and limits the cover plate's movement, enhancing its smoothness and precision. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a vacuum tempering furnace with uniform heating, including a base plate 1, two supports 3 are fixedly connected to the top of the base plate 1, and a vacuum tempering furnace body 4 is fixedly connected to the top of the two supports 3. A cover plate 5 is provided on one side of the vacuum tempering furnace body 4, and a plurality of sliding holes 9 are opened on the vacuum tempering furnace body 4, and the plurality of sliding holes 9 are evenly distributed on the vacuum tempering furnace body 4.

[0021] A motor 6 is fixedly connected to one side of the cover plate 5. The output shaft of the motor 6 passes through the cover plate 5 and is fixedly connected to a turntable 11. Several fixed clamping plates 12 are fixedly connected to one side of the turntable 11, and several fixed plates 15 are fixedly connected to one side of the turntable 11. A sliding rod 10 is slidably connected inside the sliding hole 9. Because of the sliding rod 10, when the cover plate 5 moves, the sliding rod 10 slides inside the sliding hole 9. The sliding rod 10 plays a supporting role for the cover plate 5, so that the cover plate 5 will not fall off while sliding, thus improving the stability of the cover plate 5. Moreover, the sliding rod 10 plays a limiting and guiding role for the cover plate 5, thus improving the smoothness and accuracy of the movement of the cover plate 5. One end of the sliding rod 10 is fixed to the cover plate 5.

[0022] Two movable rods 13 are slidably connected to the fixed plate 15. Because of these movable rods 13, when the movable clamping plate 16 moves, the movable rods 13 slide on the fixed plate 15, thus limiting and guiding the movement of the movable clamping plate 16 and improving its stability. A pull plate 14 is fixedly connected to one end of each of the two movable rods 13. Pulling the pull plate 14 facilitates the movement of the movable rods 13 and the movable clamping plate 16, moving the movable clamping plate 16 away from the object, thereby facilitating the removal of the object and improving operation. For ease of use, the other end of the two movable rods 13 is fixedly connected to a movable clamping plate 16. The movable clamping plate 16 has an arc-shaped design. When the object comes into contact with the arc surface of the movable clamping plate 16, it will push the movable clamping plate 16 away a certain distance, so that the object can be fixed by the spring 17, thus improving the ease of operation. The movable clamping plate 16 corresponds to the fixed clamping plate 12. Two electric push rods 8 are fixedly connected to one side of the upright plate 2. One end of the two electric push rods 8 is fixedly connected to a connecting plate 7, and the connecting plate 7 is fixed to the motor 6.

[0023] A spring 17 is sleeved on the movable rod 13. One end of the spring 17 is fixedly connected to the movable clamping plate 16, and the other end of the spring 17 is fixedly connected to the fixed plate 15. There are several sliding rods 10, which are evenly distributed on one side of the cover plate 5. A vertical plate 2 is fixedly connected to the top of the bottom plate 1.

[0024] The working principle of this utility model is as follows:

[0025] When in use, start the electric push rod 8 to drive the connecting plate 7, motor 6, cover plate 5 and slide rod 10 to move to the right. The slide rod 10 will slide inside the sliding hole 9. At the same time, the slide rod 10 supports the cover plate 5 so that the cover plate 5 will not fall off while sliding. At this time, place the item to be heated between the fixed clamping plate 12 and the movable clamping plate 16. When the item comes into contact with the arc surface of the movable clamping plate 16, it will push the movable clamping plate 16 away a certain distance and fix the item by the pressure of the spring 17.

[0026] At this point, the electric push rod 8 is activated, causing the connecting plate 7, motor 6, cover plate 5, and slide rod 10 to move to the left until the item enters the vacuum tempering furnace body 4. The vacuum tempering furnace body 4 and motor 6 are then activated, and the vacuum tempering furnace body 4 heats the item. The motor 6 drives the item to rotate, thus achieving uniform heating. After heating is complete and the item has cooled down, the electric push rod 8 is activated, causing the connecting plate 7, motor 6, cover plate 5, and slide rod 10 to move to the right, allowing the item to be sent out of the vacuum tempering furnace body 4. At this point, the pull plate 14 is pulled, causing the movable rod 13 and movable clamping plate 16 to move away from the item, allowing the item to be removed.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
