Description

Technical Field

[0001] This utility model relates to the field of high alumina brick shaping technology, specifically to a pressure shaping machine for irregularly shaped high alumina bricks. Background Technology

[0002] High-alumina shaped bricks, also known as high-alumina bricks or irregularly shaped high-alumina bricks, are a special type of refractory material mainly used for furnace linings in industrial kilns. Their main component is alumina, typically exceeding 48%, and can even reach over 90% (in which case they are called corundum bricks). Furthermore, due to the presence of thermally conductive materials such as mullite and corundum crystals within the high-alumina bricks, they exhibit excellent thermal conductivity; their refractoriness can reach 1750-1790℃, far exceeding that of clay bricks and semi-silica bricks.

[0003] High-alumina shaped bricks have a wide range of applications in industrial fields, such as metallurgy, building materials, environmental protection, power, and glass, and are especially suitable for use in high-temperature environments of 1250-1500℃. The preparation of shaped high-alumina bricks typically requires vibration molding using a hydraulic press or manual tamping. Due to their complex shapes (such as multiple concave corners, grooves, or weights exceeding 100Kg), ordinary friction presses cannot be used. To improve production efficiency, pressure molding machines need to have the function of applying pressure molds to concave corners and grooves, allowing for adjustment and switching when producing bricks of different complex shapes and specifications. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pressure molding machine for irregularly shaped high-alumina bricks.

[0005] The technical solution of this utility model is: a pressure molding machine for irregular high-alumina bricks, including a base, a top plate, and an electric telescopic rod for connecting the base and the top plate, wherein the top plate is provided with a mold cavity;

[0006] The mold cavity has at least one set of adjustment components, each set of adjustment components has at least two rectangular mold slots, each rectangular mold slot has a recessed groove on one side wall, and an auxiliary adjustment block is slidably sealed in the recessed groove. The mold cavity is also provided with a drive mechanism that can simultaneously or individually drive each of the auxiliary adjustment blocks in each set of adjustment components to extend and retract.

[0007] Note: The above settings can control each irregular high-alumina brick separately. By adjusting the driving device of each brick, the position of the irregular functional block can be adjusted, thereby realizing the adjustment of the auxiliary shaping block at different depths and realizing the preparation of irregular bricks with different shapes and structures.

[0008] Furthermore, the auxiliary shaping block includes a non-circular block with an arc-shaped, trapezoidal, or rectangular cross-section and a worm gear axially engaged with the non-circular block;

[0009] Note: The above structural design can adjust the axial position of the worm by limiting the worm, thereby driving the irregular functional block to adjust to different positions; in order to realize the reset of the worm when it is not driven, a spring is provided between the worm and the irregular functional block.

[0010] Furthermore, the driving mechanism includes a groove horizontally disposed on the mold cavity, multiple shafts disposed within the groove and located on the same axis, a worm gear that is limited and engaged between two adjacent shafts, multiple tension springs disposed between the worm gear and the shaft, a lever for disengaging the worm gear from the worm, and a motor for synchronously driving the rotation of each shaft; each of the two end faces of the worm gear is provided with a spring-extendable polygonal limiting block at its center, and adjacent shafts are provided with polygonal limiting grooves corresponding to the positions of the polygonal limiting blocks on their contact surfaces with the worm gear; the worm gear meshes with the worm.

[0011] Note: The above settings allow for adjustment of the worm gear position using a lever during the adjustment of the irregularly shaped functional block position, making the engagement between the worm gear and the shaft controllable. It can drive the extension and retraction of each auxiliary shaping block individually or synchronously according to the requirements of the irregularly shaped high-alumina brick, thereby improving the preparation efficiency of irregularly shaped high-alumina bricks.

[0012] Furthermore, a limiting piece is provided at the end of the worm gear;

[0013] Note: The limiting plate is used to prevent the worm gear from disengaging from the worm.

[0014] Furthermore, the base has an opening on one side, and a pull-out cavity that can be slidably provided at the opening to place the irregular high-alumina brick;

[0015] Note: The above settings enable quick handling of the prepared irregularly shaped high-alumina bricks, avoiding damage to the bricks during the handling process.

[0016] The beneficial effects of this utility model are: this utility model realizes the function of simultaneously or individually driving each auxiliary shaping block in each shaping component to extend and retract through the driving structure, which meets different usage needs, can realize the preparation of irregular bricks with different shapes and structures, and can be adjusted and switched when producing bricks with different complex shapes and specifications, so that the preparation efficiency of irregular high alumina bricks is higher.

Detailed Implementation

[0026] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0027] Example 1: As Figure 1 , Figure 2 The illustrated high-alumina brick pressure molding machine includes a base 1, a top plate 2, and an electric telescopic rod 3 for connecting the base 1 and the top plate 2. The top plate 2 is provided with a mold cavity 21.

[0028] The mold cavity 21 has 3 sets of shaping components. Each set of shaping components has 3 rectangular mold slots 211. Each rectangular mold slot 211 has a recessed groove 212 on one side wall. An auxiliary shaping block 213 is slidably sealed in the recessed groove 212. The mold cavity 21 is also provided with a drive mechanism 214 that can simultaneously or individually drive each auxiliary shaping block 213 in each set of shaping components to extend and retract.

[0029] In this embodiment, the drive mechanism 214 adopts a commercially available drive motor. The drive motor is electrically connected to each of the auxiliary shaping blocks 213 and is used to drive the auxiliary shaping blocks 213 to move to the target position. The cross-section of the irregular block 2131 is arc-shaped.

[0030] The working principle of this embodiment is as follows: the driving mechanism 214 drives each auxiliary shaping block 213 to slide along the sink 212 to the corresponding target position. The driving mechanism 214 is turned off. At this time, the raw material of the irregular high alumina brick is placed into the base 1. Then, the electric telescopic rod 3 is adjusted to make the top plate 2 move downward, and the mold cavity 21 fixedly connected to the top plate 2 moves downward. The raw material is shaped and compacted according to the structure composed of the rectangular mold groove 211 and the auxiliary shaping block 213 in the mold cavity 21.

[0031] Example 2: Unlike Example 1, as follows Figures 3-7 As shown, the auxiliary shaping block 213 includes a shaped block 2131 with an arc-shaped cross section and a worm gear 2132 that is axially engaged with the shaped block 2131;

[0032] The drive mechanism 214 includes a groove 210 horizontally disposed on the mold cavity 21, four shafts 2141 disposed in the groove 210 and located on the same axis, a worm gear 2142 limited and engaged between two adjacent shafts 2141, six tension springs 2143 disposed between the worm gear 2142 and the shaft 2141, a lever 2144 for actuating the worm gear 2142 and the worm 2132, and a motor for synchronously driving the shafts 2141 to rotate; each end face of the worm gear 2142 is provided with a spring-extendable polygonal limiting block 2145 at the center of both sides, and a polygonal limiting groove 2146 corresponding to the position of the polygonal limiting block 2145 is provided on the contact surface between the adjacent shafts 2141 and the worm gear 2142; the worm gear 2142 meshes with the worm 2132 for transmission; a limiting piece is provided at the end of the worm 2132.

[0033] It should be noted that the lever 2144 actuates the flange on the end face of the worm gear 2142, the shaft 2141 has a collar, and one side of the tension spring 2143 contacts the collar; in this embodiment, the polygonal limiting block 2145 is a triangular prism; a second spring is provided between the worm 2132 and the irregular block 2131 for the reset of the worm 2132; the polygonal limiting block 2145 is connected to the center of the worm gear 2142 by a spring rod; it can achieve a rigid connection with the worm gear 2142 and the shaft 2141;

[0034] The working principle of this embodiment is basically the same as that of embodiment 1, except that: the worker determines the auxiliary adjustment block 213 that needs to be slidable according to the shape requirements of the irregular high-alumina brick structure, and then uses the lever 2144 to disengage the worm gear 2142 corresponding to the auxiliary adjustment block 213 that does not need adjustment, so that the worm gear 2142 is separated from the worm 2132. At this time, the polygonal limiting block 2145 and the polygonal limiting groove 2146 also disengage under the action of spring extension and contraction. The disengaged worm gear 2142 can be reset by the restoring force of the tension spring 2143 after adjustment. At this time, the motor is turned on to drive the various shafts 2141 that have not disengaged to rotate, which can synchronously drive the worm gear 2142 to rotate. Under the meshing transmission action of the worm gear 2142 and the worm 2132, the worm 2132 is driven to move axially, thereby realizing the efficient adjustment of the position of the irregular block 2131. After the brick making is completed, the motor reverses, and the worm 2132 is reset to the initial state under the joint action of the second spring and the worm gear 2142. The above settings can make the shaping efficiency higher.

[0035] Example 3: Unlike Example 2, the cross-section of the irregular block 2131 is trapezoidal.

[0036] Example 4: Unlike Example 2, the cross-section of the irregular block 2131 is rectangular.

[0037] Example 5: Unlike Example 2, as follows Figure 8 As shown, the base 1 has an opening on one side, and a pull-out cavity 11 that can hold irregularly shaped high-alumina bricks is slidably provided at the opening;

[0038] The working principle of this embodiment is basically the same as that of embodiment 2. The difference is that the above setting can facilitate the opening of the pull-out cavity 11 after the irregular high alumina brick is prepared, so as to take out the irregular high alumina brick and avoid damage to the brick during the handling process.
