[0019] The present utility model will now be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.

[0020] Please refer to Figures 1 - 5 , a cover-type furnace with a variable cavity moving mechanism, which includes a lifting furnace body 1 and a moving trolley 2 below the lifting furnace body 1. The moving trolley 2 can move horizontally below the lifting furnace body 1. A heat preservation board 4 is provided on the surface of the moving trolley 2, and a plurality of moving partitions 5 are vertically provided on the heat preservation board 4. When the moving trolley 2 is directly below the lifting furnace body 1, the moving partitions 5 divide the lifting furnace body 1, and a plurality of heating cavities are formed between every two adjacent moving partitions 5 and between the moving partitions 5 and the lifting furnace body 1. When in use, workpieces can be placed in any one of the heating cavities according to their volume.

[0021] In the solution of the present utility model, ear plates 11 extending outward are provided at the four corners of the lifting furnace body 1, and hydraulic rods 12 are connected below the ear plates 11. The four hydraulic rods 12 operate simultaneously to drive the lifting furnace body 1 to vertically lift and lower.

[0022] Wherein, two parallel trolley tracks 3 are provided below the lifting furnace body 1, and rollers 21 cooperating with the trolley tracks 3 are provided at the bottom of the moving trolley 2. The moving trolley 2 moves along the tracks through the rollers 21.

[0023] When in use, the workpiece to be heated is placed in any one or more heating cavities. Then, the hydraulic rods 12 are first started. At this time, the lifting furnace body 1 is raised by the hydraulic rods 12, and then the moving trolley 2 moves to directly below the lifting furnace body 1. Then the hydraulic rods 12 are started again to retract, causing the lifting furnace body 1 to descend and cover the periphery of the moving trolley 2. The heating elements in the lifting furnace body 1 can operate to heat the workpieces in the heating cavities.

[0024] After heating is completed, the hydraulic rods 12 are raised again, and then the moving trolley 2 is moved out, and the workpiece can be taken out. This process can shorten the time for the workpiece to enter and exit, avoid heat loss. At the same time, the horizontal movement of the moving partitions 5 can adjust the size of the heating cavity, and the workpiece can be placed in the applicable heating cavity according to requirements, increasing the applicable range.

[0025] In this embodiment, the heat preservation board 4 is fixed on the surface of the moving trolley 2 by bolts 41. An inverted T-shaped chute 42 is provided along the length direction of the heat preservation board 4. A slider cooperating with the T-shaped chute 42 is provided at the bottom of the moving partition 5, and the moving partition 5 can translate along the T-shaped chute 42.

[0026] On both sides of the movable partition 5, integral connecting blocks 51 are provided. Fixed bolts are provided on the connecting blocks 51. After the position of the movable partition 5 is determined, the fixed bolts are tightened and abutted against the surface of the heat preservation board 4, so as to prevent the movable partition 5 from shifting.

[0027] In this embodiment, the number of movable partitions 5 can be increased or decreased according to requirements, further improving the scope of application.

[0028] As a preferred solution, first heating elements 6 are respectively provided on both sides of the movable partition 5, and a plurality of groups of second heating elements 7 are provided on the inner top surface of the lifting furnace body 1. The second heating elements 7 correspond to the heating chambers one by one.

[0029] The first heating elements 6 on both sides of the movable partition 5 are independently arranged and can be started for heating separately or simultaneously; the plurality of groups of second heating elements 7 are also independently arranged and can be started for heating separately or simultaneously.

[0030] After the workpiece is placed in the heating chamber, the corresponding first heating element 6 and second heating element 7 operate, and other heating elements are turned off; thus, the workpiece is heated specifically, and the power consumption can be saved.

[0031] For example, please refer to again Figure 4 , Figure 4 There are two movable partitions 5 arranged in it. The two movable partitions 5 divide the lifting furnace body 1 into three heating chambers. After the workpiece is placed in one of the heating chambers, the corresponding first heating element 6 and second heating element 7 operate for heating, avoiding all heating elements from working and wasting electric energy.

[0032] In this embodiment, the first heating element and the second heating element are both traditional devices in the heating furnace and play the role of raising the temperature to heat the workpiece, and no more details will be described here.

[0033] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
