Description

Technical Field

[0001] This utility model relates to the field of checker brick forming mold technology, and in particular to an anti-clogging checker brick punch. Background Technology

[0002] Checker bricks are a special type of refractory brick commonly used in the regenerators of industrial furnaces (such as blast furnaces, glass kilns, and coke ovens). They are named for their "grid" structure, which is characterized by regularly arranged holes or channels. The interior is honeycomb-like or grid-like with dense longitudinal channels, increasing the heat exchange area. The porosity (pore ratio) is high, usually above 50%, to optimize heat storage efficiency. They are typically made of high-temperature resistant and corrosion-resistant refractory materials, such as clay, high-alumina, magnesia, or silica materials. In the regenerator, they alternately absorb heat from waste gas and then transfer the heat to the incoming cold air or fuel gas, improving fuel utilization.

[0003] The checkered bricks are mostly hexagonal in shape, with 7, 19, or 37 circular or irregularly shaped channels evenly distributed in a triangular stacking pattern inside. In the mold, these channels are filled by the mold core, and the mold cover plate is connected to the punch. The mold core is inserted and the blank is pressed down to achieve the shape. Some existing mold punches are made by drilling corresponding circular holes from a solid round steel piece. Because the channels are deep and closed, they are difficult to clean, easily accumulate blanks and become blocked, thus jamming the mold core and damaging the mold. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of some existing mold punches, which are made by drilling corresponding round holes from a solid round steel. Due to the deep and closed channels, they are inconvenient to clean and easily accumulate blanks and block the mold core, thereby jamming the mold core and damaging the mold. This utility model provides a blockage-proof checker brick punch.

[0005] The purpose of this utility model is achieved through the following technical solution: a blockage-proof grid brick punch, including an upper cover, a lower cover, and a triangular top post assembly, which are connected as a whole. The upper cover and the lower cover are parallel to each other, and the triangular top post assembly is located between the upper cover and the lower cover. The longitudinal center line of the triangular top post assembly is perpendicular to the inner end face of the upper cover and the lower cover. There are two application scenarios for this punch: when making the upper punch, the outer end face of the upper cover is connected to the mold cover plate, and the lower cover is connected to a pressure source; when making the lower punch, the outer end face of the upper cover is connected to the mold base plate, and the lower cover is connected to a top force source.

[0006] A further technical solution is that the outer contour of the upper cover is adapted to the inner contour of the mold cavity, the outer contour dimension of the upper cover is smaller than the dimension of the mold cavity, the internal hole system of the upper cover is adapted to the distribution of the mold core, and the internal hole system dimension of the upper cover is larger than the diameter of the mold core.

[0007] A further technical solution is that the outer contour of the lower cover is adapted to the pressure source or top force source, and when used as a lower punch, the internal hole system of the lower cover is adapted to the distribution of the mold core, and the size is larger than the diameter of the mold core.

[0008] A further technical solution is that the triangular top column assembly is composed of several individual units, each of which has a cross-section of a triangular shape composed of three fins. The included angle between the three fins is 120°, and its external contour shape is adapted to the shape of the mold core, with gaps left between adjacent units.

[0009] A further technical solution is that the pressure source is installed under the press beam; the top force source is installed on the press base; and the mold cavity is installed on the worktable. Both are located between the press beam and the press base, and the press beam and the press base are connected by the press column.

[0010] The utility model has the following advantages: The present utility model is composed of an upper cover, a triangular top post and a lower cover. The triangular top post is designed with triangular shape to have good support strength. It makes maximum use of the triangular area between the holes of the grid brick, increases the effective diameter of the top post, and greatly improves the rigidity and durability of the top post. In addition, there are gaps between multiple sets of triangular top posts. For blanks that leak into the gaps, they can be cleaned in time by high-pressure gas or mechanical means through the gaps, thereby achieving the purpose of preventing blockage.
