Description

Technical Field

[0001] This utility model relates to the field of brick production equipment technology, specifically to a silicon carbide wear-resistant and erosion-resistant brick pressing and molding device. Background Technology

[0002] Silicon carbide wear-resistant and erosion-resistant bricks are high-performance refractory materials made primarily from silicon carbide. They possess a variety of excellent properties and are widely used in multiple industrial fields. In the production process of silicon carbide wear-resistant and erosion-resistant bricks, pressing and molding is a crucial step, and traditional brick pressing and molding equipment often has many problems.

[0003] On the one hand, during the pressing process, due to the unreasonable structural design of the pressing device, the pressure applied to the brick blank is uneven, which will cause uneven density of the brick blank and internal defects are easy to occur, thus affecting the quality of silicon carbide wear-resistant and corrosion-resistant bricks, reducing their wear resistance and corrosion resistance, and failing to meet the requirements of use under some special working conditions, such as the lining of industrial kilns in high temperature and strong corrosion environments.

[0004] On the other hand, in the process of transferring brick blanks after molding, traditional equipment lacks an efficient and convenient transfer method. It often requires manual and complicated operations to remove and transfer the brick blanks from the molding mold. This is not only inefficient, but also easy to damage the brick blanks during the operation, increasing production costs and product defect rate. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a silicon carbide wear-resistant and corrosion-resistant brick pressing and molding device.

[0006] The technical solution of this utility model is: a silicon carbide wear-resistant and corrosion-resistant brick pressing and molding device, including an operating table, a pressing unit disposed on the side wall of the operating table, and a transfer molding unit disposed on the operating table;

[0007] The pressing unit includes a mounting frame, a pressing horizontal plate located at the bottom end of the mounting frame via a hydraulic cylinder, and a plurality of extrusion blocks located at the bottom end of the pressing horizontal plate.

[0008] The transfer molding unit includes a mounting vertical rod driven by a rotary motor, multiple connecting horizontal rods arranged circumferentially on the outer wall of the mounting vertical rod, multiple receiving plates connected one-to-one with the free ends of each of the connecting horizontal rods, and a transfer plate snapped onto the receiving plate and having an extrusion molding groove inside that corresponds one-to-one with the extrusion block. A first annular sliding groove is provided on the operating table and located around the connecting horizontal rods. A first sliding reinforcing block is provided at the bottom of each receiving plate and is slidably connected to the first annular sliding groove.

[0009] Furthermore, the mounting frame has an auxiliary reinforcing frame with an open bottom end, the pressing cross plate is located inside the auxiliary reinforcing frame, and both ends of the pressing cross plate can slide up and down along the inner wall of the auxiliary reinforcing frame.

[0010] Explanation: When the hydraulic cylinder drives the pressing plate to move up and down and squeeze the brick blank in the extrusion forming groove, the left and right ends of the pressing plate are limited by the auxiliary reinforcing frame, so that it moves up and down accurately in the vertical direction, improves the uniform distribution of pressure applied by the extrusion block to the brick blank, thereby improving the density uniformity of the brick blank and reducing internal defects of the brick blank caused by uneven pressure.

[0011] Furthermore, a reinforcing connecting rod is provided between two adjacent connecting crossbars, and a second sliding reinforcing block is provided at the bottom end of each reinforcing connecting rod. A second annular sliding groove is provided on the operating table, and each of the second sliding reinforcing blocks is slidably connected to the second annular sliding groove.

[0012] Explanation: When the extrusion block extrudes the brick blank, the vertical rod is rotated by a rotary motor. When the transfer plate is directly below the pressing plate, the pressing plate is moved downward by a hydraulic cylinder. Due to the pressure applied to the brick blank by the extrusion block, in order to ensure the stability of the receiving plate on the remaining connecting rods, a reinforcing connecting rod is set between two adjacent connecting rods. This forms a more stable frame structure between the connecting rods, providing a more stable support foundation for the receiving plate. During rotation, the second sliding reinforcing block at the bottom of the reinforcing connecting rod slides in the corresponding second annular sliding groove to provide a support point, which can better resist the deformation and shaking caused by the pressure applied by the extrusion block.

[0013] Furthermore, the receiving plate has a plurality of insertion holes evenly distributed circumferentially along the upper edge, and the transfer plate has insertion posts corresponding to each insertion hole at its bottom end.

[0014] Note: The insertion pins at the bottom of the transfer plate are inserted into the corresponding insertion holes at the top of the receiving plate, which facilitates installation. After the extrusion block finishes extruding the brick blank, the transfer plate is removed by an external robotic arm, thereby achieving the purpose of transferring the brick blank and realizing efficient transfer of the brick blank, further improving production efficiency.

[0015] Furthermore, the outer wall of the transfer tray is fitted with a fixed outer sleeve, and the fixed outer sleeve and the bottom end of the transfer tray form an installation cavity. Each extrusion molding groove has a top plate at its bottom end. The installation cavity is equipped with a horizontal lifting plate driven by a micro electric telescopic rod. The horizontal lifting plate is equipped with multiple connecting columns that penetrate into the extrusion molding groove and are connected to the bottom ends of each top plate one by one.

[0016] Explanation: To facilitate the ejection of the extruded brick blanks, a micro electric telescopic rod drives a horizontal lifting plate to move upward within the installation cavity. The corresponding top plate and the brick blank located at the top of the top plate are then ejected via connecting columns. This reduces manual intervention and improves the continuity and stability of production.

[0017] The beneficial effects of this utility model are:

[0018] In use, the silicon carbide wear-resistant and corrosion-resistant brick pressing and molding device of this utility model uses a rotary motor to drive the mounting vertical rod to rotate, causing the transfer disks located in various positions to rotate sequentially to the lower end of the pressing horizontal plate. The extrusion blocks then extrude the brick blanks. After the extrusion blocks have finished extruding the brick blanks, the external robotic arm can easily remove the transfer disks, thereby achieving the purpose of transferring the brick blanks and realizing efficient transfer of brick blanks, further improving production efficiency. During the transfer process, the first sliding reinforcement block at the bottom of each transfer disk slides in the first annular sliding groove, which can better resist the deformation and shaking caused by the pressure applied by the extrusion blocks. The second sliding reinforcement block at the bottom of the reinforcing connecting rod slides in the corresponding second annular sliding groove to provide a support point, further enhancing the stability of the equipment during operation.

Detailed Implementation

[0024] Example 1: As Figure 1 ,2 As shown in Figures 1 and 3, a silicon carbide wear-resistant and corrosion-resistant brick pressing and molding device includes an operating table 1, a pressing unit 2 disposed on the side wall of the operating table 1, and a transfer molding unit 3 disposed on the operating table 1.

[0025] The pressing unit 2 includes a mounting frame 20, a pressing horizontal plate 22 located at the bottom of the mounting frame 20 via a hydraulic cylinder 21, and nine extrusion blocks 23 located at the bottom of the pressing horizontal plate 22. The hydraulic cylinder 21 adopts existing technology, such as an existing piston hydraulic cylinder.

[0026] The transfer molding unit 3 includes a mounting vertical rod 31 driven by a rotary motor 30, four connecting horizontal rods 32 arranged circumferentially on the outer wall of the mounting vertical rod 31, four receiving plates 33 connected one-to-one with the free ends of each connecting horizontal rod 32, and a transfer plate 34 snapped onto the receiving plate 33 and having an extrusion molding groove 340 inside that corresponds one-to-one with the extrusion block 23. A first annular sliding groove 10 is provided on the operating table 1 and located around the connecting horizontal rods 32. A first sliding reinforcing block 330 is provided at the bottom of each receiving plate 33 and is slidably connected to the first annular sliding groove 10. The rotary motor 30 adopts existing technology, such as a Z-series DC motor.

[0027] The mounting frame 20 has an auxiliary reinforcing frame 24 with an open bottom end. The pressing plate 22 is located inside the auxiliary reinforcing frame 24, and both ends of the pressing plate 22 can slide up and down along the inner wall of the auxiliary reinforcing frame 24. When the hydraulic cylinder 21 drives the pressing plate 22 to move up and down and press the brick blank in the extrusion forming groove 340, the auxiliary reinforcing frame 24 limits the left and right ends of the pressing plate 22, so that it moves up and down accurately in the vertical direction, improves the uniform distribution of the pressure applied by the extrusion block 23 to the brick blank, thereby improving the density uniformity of the brick blank and reducing internal defects of the brick blank caused by uneven pressure.

[0028] A reinforcing connecting rod 320 is provided between two adjacent connecting crossbars 32. Each reinforcing connecting rod 320 has a second sliding reinforcing block 321 at its bottom end. The operating table 1 is provided with a second annular sliding groove 11. Each second sliding reinforcing block 321 is slidably connected to the second annular sliding groove 11. Due to the pressure applied to the brick blank by the extrusion block 23, in order to ensure the stability of the installation of the receiving plate 33 on the remaining connecting crossbars 32, a reinforcing connecting rod 320 is provided between two adjacent connecting crossbars 32. This forms a more stable frame structure between the connecting crossbars 32, providing a more stable support foundation for the receiving plate 33. During rotation, the second sliding reinforcing block 321 at the bottom end of the reinforcing connecting rod 320 slides in the corresponding second annular sliding groove 11 to provide a support point, which can better resist the deformation and shaking caused by the pressure applied by the extrusion block 23.

[0029] like Figure 3 ,4 As shown, the receiving plate 33 has 12 insertion holes 331 evenly arranged circumferentially along the upper edge of the receiving plate 33, and the bottom of the transfer plate 34 has insertion posts 341 corresponding to the insertion holes 331. The insertion posts 341 at the bottom of the transfer plate 34 are inserted into the insertion holes 331 at the upper end of the receiving plate 33, which facilitates installation. After the extrusion block 23 finishes extruding the brick blank, the transfer plate 34 is removed by an external robotic arm, thereby achieving the purpose of transferring the brick blank and realizing the efficient transfer of the brick blank, further improving production efficiency.

[0030] The outer wall of the transfer plate 34 is fitted with a fixed outer sleeve 35, and the fixed outer sleeve 35 and the bottom end of the transfer plate 34 form an installation cavity 350. Each extrusion forming groove 340 has a top plate 342 placed at its bottom end. The installation cavity 350 is equipped with a horizontal lifting plate 352 driven by a micro electric telescopic rod 351. The horizontal lifting plate 352 has nine connecting columns 353 that penetrate into the extrusion forming groove 340 and are connected to the bottom ends of each top plate 342. In order to facilitate the ejection of the extruded brick blank, the horizontal lifting plate 352 is driven by the micro electric telescopic rod 351 to move upward in the installation cavity 350, and the corresponding top plate 342 and the brick blank located on the top plate 342 are ejected through the connecting columns 353. This reduces manual intervention and improves the continuity and stability of production. The micro electric telescopic rod 351 adopts existing technology, such as the HB-DJ806 micro electric telescopic rod.

[0031] The method of using the silicon carbide wear-resistant and corrosion-resistant brick pressing and molding device according to this embodiment includes the following steps:

[0032] S1. Place brick blanks into the extrusion forming grooves 340 on each transfer plate 34. Drive the mounting rod 31 to rotate by the rotary motor 30. When one of the transfer plates 34 is located directly below the pressing horizontal plate 22, drive the pressing horizontal plate 22 to move up and down by the hydraulic cylinder 21 and extrude the brick blanks in the extrusion forming grooves 340 to form brick blanks. During the above movement, the first sliding reinforcement block 330 slides in the first annular sliding groove 10, thereby providing a support point for the bottom of each transfer plate 34.

[0033] S2. After extrusion, the vertical rod 31 is driven to continue rotating by the rotary motor 30, so that the second transfer plate 34 is located at the lower end of the pressing plate 22. The hydraulic cylinder 21 is used to drive the pressing plate 22 to move up and down and extrude the brick blank in the extrusion forming groove 340 to form a brick blank.

[0034] S3. After the brick blanks in each transfer plate 34 are compressed into brick blanks, the transfer plate 34 is removed by an external robotic arm. Then, the horizontal lifting plate 352 is driven to move upward in the installation cavity 350 by the micro electric telescopic rod 351, and the corresponding top plate 342 and the brick blanks located on the top plate 342 are pushed out by each connecting column 353, and then subsequent processing is carried out.
