Description

Technical Field

[0001] The utility model relates to the technical field of alumina-magnesia-carbon bricks, and specifically, to a press for alumina-magnesia-carbon bricks. Background Art

[0002] Alumina-magnesia-carbon bricks are carbon-containing refractory materials mainly composed of Al2O3, MgO and C, containing 60% - 69% Al2O3, 7% - 14% MgO, and 5% - 12% C. It has good slag erosion resistance and thermal shock resistance, with a small amount of re-firing expansion. To improve its oxidation resistance, additives such as Si powder, Al powder, SiC powder or ferrosilicon powder can be appropriately added to the formulation. Using resin as the binder, it is formed under high pressure and can be used after being treated at 200 - 300°C without calcination. It is mainly used for the lining of large converters, ultra-high power electric furnace ladles and secondary refining furnace linings, etc.

The outer surface of the threaded rod 204 is threadedly connected with a threaded ring 202. The outer surface of the threaded ring 202 is fixedly connected with two movable plates 13. The upper surface of each movable plate 13 is fixedly connected with a push rod 206. The upper surface of the push rod 206 penetrates through the bottom shell 1 and extends into the die cavity 205. The upper surface of the push rod 206 is fixedly connected with a push plate 209. The upper surface of the bottom shell 1 is fixedly connected with two support columns 7. The upper surface of the support columns 7 is fixedly connected with a support plate 3. The upper surface of the support plate 3 is fixedly connected with a hydraulic push rod 5. The telescopic end of the hydraulic push rod 5 is fixedly connected with a punch 6.

[0026] Referring to Figure 4 , a through ring 14 is fixedly embedded in the bottom surface of the support plate 3. The telescopic end of the hydraulic push rod 5 penetrates through the through ring 14 and extends to the lower part of the support plate 3, which can effectively reduce the friction between the telescopic end of the hydraulic push rod 5 and the support plate 3 during the movement process, effectively avoid the wear of the telescopic end of the hydraulic push rod 5 caused by long-term use, and avoid affecting the normal use of the hydraulic push rod 5 in the later stage.

[0027] Referring to Figures 4 to 5 , two inclined plates 4 are fixedly connected to the outer surface of the hydraulic push rod 5. The bottom end of each inclined plate 4 is fixedly connected to the upper surface of the support plate 3, which can further fix the hydraulic push rod 5, improve the stability of the hydraulic push rod 5 during use, effectively avoid the shaking of the hydraulic push rod 5 during use, and thus avoid affecting the normal operation of the hydraulic push rod 5.

[0028] Referring to Figures 2 to 3 , a bearing 11 is fixedly connected to the inner top wall of the cavity 203. The top end of the threaded rod 204 is fixedly connected to the inner ring of the bearing 11, which can effectively prevent the top end of the threaded rod 204 from swinging due to centrifugal force, improve the stability of the threaded rod 204 during use, and thus avoid affecting the cooperation between the threaded rod 204 and the threaded ring 202.

[0029] Example 2

[0030] As Figures 2 to 3 shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a fixing ring 10 is fixedly connected to the outer surface of the servo motor 201, and the bottom surface of the fixing ring 10 is fixedly connected to the inner bottom wall of the cavity 203, further fixing the servo motor 201, improving the stability of the servo motor 201 during use, effectively avoiding the shaking of the servo motor 201 during use, and thus avoiding affecting the normal operation of the servo motor 201.

[0031] Referring Figures 2 to 3 , two sets of sliding rods 207 are fixedly connected to the inner bottom wall of the cavity 203. A sliding ring 208 is slidably connected to the outer surface of each sliding rod 207. One ends of the two sets of movable plates 13 away from the screw ring 202 are respectively fixedly connected to the outer surfaces of the two sets of sliding rings 208, which can effectively ensure the stability of the movable plates 13 during movement, effectively avoid the deviation and jamming of the movable plates 13 during movement, and thus avoid affecting the normal use of this press.

The tops of the two sets of push rods 206 respectively penetrate through the two through holes 12 and extend into the inside of the die cavity 205, which can effectively reduce the friction between the push rods 206 and the bottom shell 1, effectively avoid the wear on the outer surface of the push rods 206 caused by long-term use, and thus avoid affecting the subsequent normal use of the push rods 206.

[0033] Referring Figures 2 to 3 , a fixing plate 16 is fixedly connected to the back surface of the bottom shell 1, and a storage hopper 15 is fixedly connected to the upper surface of the fixing plate 16, which can store the tools for daily maintenance of the press, avoid the random placement of tools, and thus avoid the loss of tools.

[0034] Referring Figures 1 to 3 , a base 9 is fixedly connected to the bottom surface of the bottom shell 1, and an operation nameplate 8 is fixedly connected to the front surface of the base 9, which can effectively increase the contact area between the bottom surface of the bottom shell 1 and the ground, thereby improving the stability of this press during placement. At the same time, the operation method is engraved on the operation nameplate 8 to prevent the staff from operating according to the correct operation method after reading.

[0035] During use, the hydraulic push rod 5 pushes the punch 6 to perform pressure forming on the raw materials inside the female die groove 205. After the forming is completed, the hydraulic push rod 5 drives the punch 6 to reset. The servo motor 201 drives the threaded rod 204 to rotate, and the threaded rod 204 drives the threaded ring 202 to move on the threaded rod 204. The threaded rod 204 drives the two groups of movable plates 13 to move upward. The movable plates 13 push the push plate 209 through the push rod 206, and the push plate 209 pushes the bricks out of the female die groove 205. The staff can then remove the bricks. After that, the servo motor 201 rotates in reverse, causing the threaded rod 204 to drive the threaded ring 202 to move downward, and the push rod 206 drives the push plate 209 to reset. Then, the press performs the next forming operation.
