Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a tool for processing the riser of a liner of a ball mill. Background Art

[0002] Ball mill liners are protective plates for the mill's cylinder and inlet and outlet ports. They primarily protect the cylinder from direct impact and abrasion from the grinding media and material, thereby extending its service life. Different liner designs can also adjust the motion of the grinding media within each chamber of the mill. Because the motion of the grinding media significantly influences grinding efficiency, adjusting the liner shape can alter the motion of the media to better suit the grinding process, thereby improving grinding efficiency, increasing output, and reducing metal consumption. Furthermore, ball mill liners offer high wear and impact resistance, as well as high strength and toughness. They can withstand significant impacts and maintain their surface shape over time, ensuring stable mill operation. These characteristics make ball mill liners crucial in industrial production.

[0003] In existing technology, ball mill liners weigh approximately 45-55 kg due to installation constraints. The riser diameter of the ball mill liner, installed during the casting process, is approximately 180-200 mm. Manual hammering to remove the riser requires repeated striking, making it difficult to break, a time-consuming and labor-intensive process. Using an air hammer to strike the riser deforms the ball mill liner and makes it difficult to clamp. The combined weight of the ball mill liner and riser is less than 120 kg, making it easy for the liner to be knocked off and damage the casting. Utility Model Content

[0004] (1) Technical issues to be resolved

[0005] The utility model provides a tool for processing the riser of a liner of a ball mill, aiming to solve the problem that the process of removing the riser of the liner of the ball mill is time-consuming and labor-intensive.

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0024] This embodiment provides a tool for processing the riser of the liner of a ball mill, such as Figure 1 As shown, it includes a tool body 1 and a crowbar 2. The tool body 1 is provided with a contoured groove 11 that matches the shape of the liner 3. The contoured groove 11 is open at the top and can accommodate and retain the liner 3. The bottom of each contoured groove 11 is provided with a prying groove 12, and the rear side wall is provided with a first notch 13 that runs through the front and back. The prying groove 12 is connected to the first notch 13, and the first notch 13 is located above the prying groove 12. The crowbar 2 can be inserted into the prying groove 12 and move along the first notch 13 in the vertical direction. The upward prying of the crowbar 2 can pry the liner 3 out of the contoured groove 11 after the riser 4 is knocked off.

[0025] Specifically, in this embodiment, the tool body 1 has two contoured grooves 11, but the number can be more. The shape of the contoured groove 11 is designed and manufactured based on the outer contour of the liner 3. During the design and manufacturing process, a certain gap must be ensured between the inner wall of the contoured groove 11 and the liner 3. This gap allows the liner 3 to be placed more conveniently in the contoured groove 11.

[0026] It should be noted that a riser refers to a cavity within a mold specifically designed to hold molten metal, and also refers to the metal filled within that cavity. It is a supplementary portion added to the top or side of a casting to prevent defects. In this example, riser 4 is located above liner 3. During the workpiece processing, riser 4 needs to be removed. In this embodiment, this is done by hammering with an air hammer.

[0027] The above-described embodiment can achieve the following technical effects: the contoured groove 11 on the tool body 1 in this embodiment is designed and manufactured to imitate the outer shape of the liner 3, which can effectively limit and clamp the liner. (It should be noted here that the mass of the liner 3 in this embodiment is approximately 45 kg, and the combined mass of the liner 3 and the riser 4 is less than 100 kg. The liner 3 can easily be knocked away or damaged. When the tool body 1 is added, the total weight can reach more than 600 kg, and the air hammer will not knock the liner 3 away during the impact. This saves time and effort and improves production efficiency).

[0028] Reference Figure 1 In this embodiment, a second notch 14 is further provided on the tool body 1 , and the second notch 14 is connected to the profiling groove 11 and corresponds to the inner runner when the liner 3 is located in the profiling groove 11 .

[0029] It should be noted here that the ingrowth is the last section of the channel for liquid metal to enter the mold cavity in the mold, and is also an important part of the pouring system. The ingrowth can control the speed and direction of the molten metal filling the mold, ensuring that the molten metal enters the mold cavity smoothly. Through the design of the ingrowth, the temperature of each part of the mold can be adjusted, thereby affecting the solidification order of the casting. The ingrowth of the liner 3 in this embodiment is located on the side of the liner 3, and only preliminary processing is performed before the riser 4 is removed by impact. Some residual parts of the ingrowth after knocking out still remain on the liner 3. The second notch 14 in this embodiment is for placing or accommodating this part of the residual part of the ingrowth.

[0030] Reference Figure 1 In this embodiment, a third notch 15 is further provided on the tool body 1 and runs through the tool body 1 from top to bottom. The third notch 15 is located opposite to the first notch 13 and communicates with the contoured groove 11 .

[0031] Specifically, the third notch 15 is mainly used to help the operator to better place the lining plate 3 into the contoured groove 11 or pry the lining plate 3 out of the contoured groove 11 .

[0032] Furthermore, the third notch 15 in this embodiment cuts the bottom of the contoured groove 11 to form a first positioning surface 16 and a second positioning surface 17. The first positioning surface 16 corresponds to the first positioning portion 31 on the lining plate 3, and the second positioning surface 17 corresponds to the second positioning portion 32 on the lining plate 3.

[0033] In this embodiment, the structural rectangular rough positioning on the lining plate 3 is utilized to make the clamping and unloading of the lining plate 3 more convenient, and at the same time can prevent the lining plate 3 from squeezing the operator's hand.

[0034] Reference Figure 1In this embodiment, the prying groove 12 is semicircular, not generally, and can also be square or other shapes. The notch edge of the prying groove 12 is tangent to the side wall of the first notch 13. It ensures that the crowbar 2 can swing up and down smoothly.

[0035] Reference Figure 1 In this embodiment, the crowbar 2 is in the shape of a round rod, and its diameter is 1 / 3-1 / 2 of the diameter of the crowbar slot 12, preferably 1 / 2.

[0036] In this embodiment, each tooling body 1 has at least two contoured grooves 11. A gap of 3-8 mm, preferably 5 mm, is provided between the inner wall of each contoured groove 11 and the liner 3 located therein. This gap facilitates loading and unloading of the liner 3. Furthermore, when the air hammer strikes the riser 4, a slight displacement occurs between the liner 3 and the sidewalls of the contoured groove 11, facilitating breakage of the riser 4.

[0037] In this embodiment, the height of the first notch 13 in the vertical direction is equal to the height of the liner 3, and the weight of the tooling body 1 is 10-15 times the weight of the liner 3. The specific multiple needs to be comprehensively referenced to the impulse of the air hammer and the mass of the riser 4.

[0038] In this embodiment, rounded corners are set at the edges of the profiling groove 11, the prying groove 12 and the first groove 13. These rounded corners can be used to protect the liner and the operator. Anti-slip grooves are set on the upper surface of the bottom of the profiling groove 11 to reduce the sliding of the liner 3 in the profiling groove 11.

[0039] In this embodiment, the bottom of the tool body 1 can also be fixed to the impact workbench through a connecting piece, which can make it more stable when the air hammer strikes.
