Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a height-adjustable vacuum heat treatment tray. Background Art

[0002] The basic principle of heat treatment is to change the internal organization and properties of the material by controlling the heating, insulation and cooling process of the material. During the heating process, the atoms and molecules inside the material will gain energy, causing their motion state and speed to change. Insulation is to make the temperature distribution inside the material uniform and ensure the consistency of the heat treatment effect. The cooling process will rearrange the atoms and molecules inside the material and form a new organizational structure, thereby changing the performance of the material. When heat treating metals, trays are usually required to hold the metal.

[0003] When using a vacuum quenching furnace to heat treat molds of different specifications, the height of the tray cannot be adjusted. Due to the height differences of different molds, their distances from the air outlet of the quenching furnace are different, which in turn is affected by the uneven furnace temperature and the difference in wind speed at different positions in the furnace. The molds closer to the air outlet will be subject to stronger thermal shock and airflow, while the molds farther away will be relatively weaker. Such differential heat treatment and cooling conditions can easily lead to abnormal deformation of the mold during the heat treatment process. Utility Model Content

[0004] The utility model aims to solve the problem that when the above equipment is in use, the height of the tray cannot be adjusted, resulting in deformation of the mold due to uneven heating, and thus proposes a vacuum heat treatment tray with adjustable height.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a height-adjustable vacuum heat treatment tray, comprising four support ribs 1, each of which has a group of air holes 2 on its top, each of which has a frame 3 fixedly sleeved on its outer walls, each of which has a mounting plate 4 fixedly sleeved on its outer walls, and each of which has a group of columns 5 in contact with the outer walls of every two of the four support ribs 1.

[0026] The column 5 includes two groups of pillars 510, and the outer walls of the two groups of pillars 510 are fixedly installed with mounting seats 520, and the outer walls of the two mounting seats 520 are fixedly installed with a group of connecting pillars 530, and the outer walls of a group of connecting pillars 530 are fixedly installed with a reinforcing plate 540. The tops of two of the four mounting plates 4 are fixedly installed with a group of cylinders 1 6, and the bottoms of the other two of the four mounting plates 4 are fixedly installed with a group of cylinders 2 7. The outer walls of a group of cylinders 2 7 are movably inserted into the interior of the cylinder 1 6. A group of threaded holes 8 are provided on the top, a mounting groove 9 is provided on the top of the four mounting plates 4, a threaded hole 2 10 is provided on the bottom of the inner wall of the four groups of mounting grooves 9, a placement groove 11 is provided on the bottom of the four mounting plates 4, a placement groove 2 12 is provided on the bottom of the four mounting plates 4, a fixing bolt 13 is threadedly connected between the inner walls of every two of the four groups of threaded holes 8, a nut 14 is threadedly connected to the outer walls of the four groups of fixing bolts 13, and a connecting plate 15 is movably inserted between the inner walls of every two of the four groups of mounting grooves 9.

[0027] The frame 3 is sleeved on the outer wall of the supporting rib 1, which can enhance the stability and firmness of the supporting rib 1 structure. The mounting plate 4 is sleeved on the outside of the frame 3, which is convenient for the installation of related components. When adjusting the height of the tray, it is only necessary to first rotate and unscrew the nut 14 from the outer wall of the fixing bolt 13, and then remove the fixing bolt 13 from the threaded hole 8, so that the top tray can be removed and the column 5 on the bottom tray can be replaced. The heights of the column 5 are 100mm, 200mm and 400mm respectively. The height of the tray can be adjusted by replacing the columns 5 of different heights. The two groups of pillars 510 of the column 5 are respectively inserted into the inside of the two supporting ribs 1, and the two circular mounting seats 520 are respectively in contact with the supporting ribs 1, thereby supporting the top tray, connecting the column 530 and the reinforcing plate 5. 40 can reinforce the column 5 as a whole to prevent the column 5 from being damaged due to excessive pressure. After the column 5 is determined, the top tray can be placed on the top of the column 5. At this time, the cylinder 2 7 on the top tray will be inserted into the cylinder 1 6. The two cylinders cooperate with each other, which can not only prevent the tray from moving during use, but also facilitate the alignment of the upper and lower threaded holes 8. Finally, the worker can screw the fixing bolt 13 into the threaded hole 8 again through the placement groove 2 12, and put the nut 14 on the surface of the fixing bolt 13, which further enhances the structural stability and prevents the tray from loosening or falling apart during use. After the adjustment is completed, the mold can be placed on the surface of the tray for heat treatment. The tray height can be adjusted according to molds of different specifications to optimize the uniformity and effect of heat treatment and reduce the defective rate.

[0028] like Figure 2-Figure 5As shown, a group of threaded holes 8 are provided on the tops of the four mounting plates 4, a group of mounting grooves 9 are provided on the tops of the four mounting plates 4, threaded holes 2 10 are provided on the bottoms of the inner walls of the four groups of mounting grooves 9, a placement groove 11 is provided on the bottoms of the four mounting plates 4, a placement groove 2 12 is provided on the bottoms of the four mounting plates 4, a fixing bolt 13 is threadedly connected between the inner walls of every two of the four groups of threaded holes 8, a nut 14 is threadedly connected to the outer walls of the four groups of fixing bolts 13, a connecting plate 15 is movably inserted between the inner walls of every two of the four groups of mounting grooves 9, a group of threaded holes 3 16 are provided on the tops of the four connecting plates 15, the inner walls of the four groups of threaded holes 3 16 are threadedly connected to the fixing bolts 2 17, the inner walls of the four groups of threaded holes 2 10 are threadedly connected to the outer walls of the fixing bolts 2 17, and the outer walls of the four groups of fixing bolts 2 17 are threadedly connected to the nuts 2 18.

[0029] When workers need to splice pallets, they can make the mounting plates 4 of the pallets fit tightly together so that the mounting grooves 9 are aligned with each other, and then they can insert the connecting plate 15 between the inner walls of the two mounting grooves 9. Finally, they only need to rotate the fixing bolts 17 into the inner walls of the threaded holes 10 and 16 opened on the tops of the connecting plate 15 and the mounting plate 4 to complete the connection between the left and right pallets. Users can flexibly combine and adjust the size and shape of the pallets according to actual needs, adapt to molds of different sizes and shapes, and avoid waste caused by purchasing too many pallets.

[0030] Working principle: When the height of the vacuum heat treatment tray needs to be adjusted, just rotate and unscrew the nut 14 from the outer wall of the fixing bolt 2 17, and then remove the fixing bolt 2 17 from the threaded hole 18 to remove the top tray. At this time, the column 5 on the bottom tray can be replaced according to needs. The column 5 provides three different heights of 100mm, 200mm and 400mm. By selecting columns 5 of different heights, the height of the tray can be adjusted. The two mounting seats 520 of the column 5 are in close contact with the supporting rib 1 to provide a stable support for the top tray. At the same time, the connecting column 530 and the reinforcement plate 540 reinforce the column 5 as a whole to ensure that even when subjected to greater pressure, the column 5 can remain stable and not easily damaged. After the column 5 is determined, only the top tray needs to be placed on the top of the column 5. At this time, the top The cylinder 2 7 on the pallet will naturally insert into the cylinder 1 6, and the two cooperate with each other, which not only effectively prevents the movement of the pallet during use, but also facilitates the alignment of the upper and lower threaded holes 8. Subsequently, the worker screws the fixing bolt 13 into the threaded hole 8 again through the placement groove 2 12, and puts the nut 14 on the surface of the fixing bolt 13. After the adjustment, the mold can be placed on the surface of the pallet for heat treatment. When the worker needs to splice the pallet to accommodate a larger or special-shaped mold, it is only necessary to make the mounting plate 4 of the pallet fit tightly, ensure that the mounting grooves 9 are aligned with each other, and then insert the connecting plate 15 between the inner walls of the two mounting grooves 9. Finally, the fixing bolt 2 17 is rotated and screwed into the inner walls of the threaded hole 2 10 and the threaded hole 3 16 opened on the top of the connecting plate 15 and the mounting plate 4, so that the two pallets can be easily connected.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
