[0001] The utility model relates to the technical field of vacuum heat treatment furnaces, in particular to a vacuum heat treatment furnace which is convenient for feeding and discharging materials. Background Art

[0002] Vacuum heat treatment is a comprehensive technology that combines vacuum technology and heat treatment. It means that all or part of the heat treatment process is carried out under vacuum. The vacuum heat treatment furnace has high thermal efficiency, can achieve rapid heating and cooling, can achieve no oxidation, no decarburization, no carburization, can remove scales on the surface of the workpiece, and has the functions of degreasing and degassing, so as to achieve the effect of surface brightness and purification. When heat treating the material, the material needs to be sent into the furnace first.

[0003] At present, when heat treating materials, most of them are placed in the furnace body in sequence, and then heat treated. After the treatment is completed, the materials are taken out of the furnace body in sequence, and then the next batch of materials can be heat treated. Taking out and putting in the workpieces in sequence is time-consuming, which reduces the processing efficiency of the workpieces. In addition, some furnaces are relatively high, making it inconvenient to place the workpieces. Utility Model Content

[0025] See also Figure 1-6 As shown, a vacuum heat treatment furnace which is convenient for loading and unloading materials comprises a furnace body 1, and also comprises: a bracket 2 arranged on the outside of the furnace body 1, a moving groove 3 for placing materials is arranged on the outside of the bracket 2, a moving rod 4 is arranged on the outside of the bracket 2, a connecting block 5 is arranged on the outside of the moving rod 4, a push rod 6 for moving the moving groove 3 to a specified position is arranged on the outside of the connecting block 5; a transmission assembly 7 for transmitting the moving rod 4 is arranged on the outside of the moving rod 4; a moving plate 12 arranged at the bottom of the bracket 2 and equipped with moving wheels, a hydraulic rod 13 is arranged on the outside of the moving plate 12, and a piston rod of the hydraulic rod 13 is provided with a support plate 14.

[0026] refer to Figure 2 and Figure 6 As shown, the transmission assembly 7 includes a motor 701 disposed on the outside of the bracket 2, a gear 702 is disposed at the output end of the motor 701, the gear 702 is fixedly connected to the moving rod 4, and a toothed plate 703 meshing with the gear 702 is disposed on the outside of the bracket 2; a limiting block 11 is fixedly connected to the outside of the motor 701, and the limiting block 11 slides inside the bracket 2. The motor 701 is limited inside a hole groove preset on the bracket 2 by the limiting block 11, and the gear 702 is driven by the motor 701 to move on the toothed plate 703, and the gear 702 drives the moving rod 4 to move synchronously.

[0027] refer to Figure 2 and Figure 3 As shown, a hanging ring 8 is provided on the outer side of the connecting block 5, and a fixing column 9 is fixedly connected to the outer side of the movable groove 3. When the movable groove 3 is moved out of the furnace body 1, the hanging ring 8 is hung on the fixing column 9, and the movable groove 3 can be pulled to move.

[0028] refer to Figure 6 As shown, the outer side of the bracket 2 is fixedly connected with a vertical plate 10, and a slide groove is provided inside the vertical plate 10 for the moving rod 4 to slide. The vertical plate 10 is provided with a slide groove, and a pulley is installed at the position of the moving rod 4 inside the slide groove. The pulley rolls inside the slide groove to reduce the friction force of the moving rod 4 when moving, so as to facilitate the movement of the moving rod 4.

When the movable groove 3 moves, the roller 16 at the bottom thereof rolls, reducing the friction between the bottom of the movable groove 3 and the contact object, making it easier for the movable groove 3 to move, and using the hanging rod 15 to conveniently hang the object to be processed.

[0030] Working principle: When moving the material to the furnace body 1 for processing, first place the material in the moving groove 3, then place the moving groove 3 on the bracket 2, and then move the bracket 2 to the entrance of the furnace body 1. At this time, the motor 701 drives the gear 702 to move on the tooth plate 703, and the gear 702 drives the moving rod 4 to move synchronously. The moving rod 4 drives the connecting block 5 and the push rod 6 to move until the moving groove 3 is completely pushed into the furnace body 1. When the material is heated and needs to be moved out, at this time, since the moving groove 3 is pushed into the furnace body 1, the moving rod 4 is located at the furnace mouth, and the hanging ring 8 is hung on the fixed column 9 on the moving groove 3. , and then control the motor 701 to reverse, so that the moving rod 4 drives the hanging ring 8 to move outward, thereby moving the mobile trough 3 out of the furnace body 1, and use the lifting equipment to move the mobile trough 3 from the bracket 2. If continuous feeding is required, another mobile trough 3 can be installed on the support plate 14, and the material is pre-loaded inside. After the mobile trough 3 on the bracket 2 is removed, the mobile plate 12 is moved to the side of the bracket 2, and the hydraulic rod 13 is turned on to drive the support plate 14 and the mobile trough 3 to rise to the same level as the upper part of the bracket 2, and then the mobile trough 3 is pushed onto the bracket 2, and then the push rod 6 is used to push the mobile trough 3 into the furnace body 1. The material change connection is faster and time is saved.
