It has the characteristics of general fibers and can be processed into various papers, tapes, cords, felts and blankets, etc. It also has the properties of high temperature resistance, corrosion resistance and oxidation resistance that ordinary fibers do not have, overcoming the brittleness of general refractory materials. At the same time, it has a very significant energy-saving effect. As a refractory thermal insulation material, it has been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.

[0003] The refractory fiber composite insulation board is formed by pressing refractory fiber and log materials. The refractory fiber composite insulation board needs to be pressed and shaped during the production process. However, when the pressing block presses the board, the board is prone to sliding and offsetting, thereby reducing the pressing effect of the refractory fiber composite insulation board. At the same time, in actual production, there will be different production requirements for thickness. However, the existing pressing device is not convenient for adaptive adjustment and is not practical.

[0004] Therefore, it is necessary to propose a pressing structure for producing an integral refractory fiber composite insulation board to solve the above problems. Utility Model Content

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1-Figure 4 A press-fit structure for producing an integral refractory fiber composite insulation board comprises a support frame 1 and a base 2 arranged on the upper side of the middle of the support frame 1, the base 2 is fixedly connected to the support frame 1, a hydraulic cylinder 4 is arranged inside the upper plate of the support frame 1, a pressing plate 5 is arranged below the hydraulic cylinder 4, a workbench 3 is fixedly installed on the top of the base 2, and positioning components 6 are arranged around the workbench 3;

[0023] The positioning assembly 6 includes an adjusting screw rod 61 movably penetrating the inside of the base 2, and both ends of the adjusting screw rod 61 extend to the inside of the side wall of the support frame 1. One end of the adjusting screw rod 61 is connected to a motor 62, and the motor 62 is fixed to the outside of the support frame 1. The outer walls of both ends of the adjusting screw rod 61 are respectively sleeved with movable blocks 63, and a limiting plate 64 is installed on the top of the movable block 63. A connecting rod 65 is connected to the outer side wall of the movable block 63. Two connecting rods 65 are symmetrically arranged. A slider 66 is rotatably arranged at one end of the connecting rod 65 away from the movable block 63. The connecting rod 65 is arranged at the bottom end of the slider 66. A guide rod 67 is movably penetrated inside the slider 66. The guide rod 67 is arranged parallel to the adjusting screw rod 61, and the guide rod 67 The two ends are installed inside the support frame 1, a moving plate 68 is arranged above the slider 66, and a limit plate 64 is arranged above the side of the moving plate 68 close to the workbench 3. The lower end of the hydraulic cylinder 4 is connected to the hydraulic telescopic rod 41, and the lower end of the hydraulic telescopic rod 41 is connected to the pressing plate 5. The pressing plate 5 is vertically arranged with the hydraulic telescopic rod 41. The hydraulic cylinder 4 controls the hydraulic telescopic rod 41 to move downward, pushing the pressing plate 5 to extrude the composite plate. The threads on the outer walls of the two ends of the adjusting screw rod 61 are in a positive and negative tooth structure, and the end thereof extending through and extending to the outside of the side wall of the support frame 1 is fixedly connected with a motor 62, so that when the motor 62 controls the rotation of the adjusting screw rod 61, the movable blocks 63 at the two ends of the adjusting screw rod 61 move relative to each other, thereby limiting the raw material and preventing it from sliding. The end of the connecting rod 65 away from the movable block 63 is arranged below the slider 66 through a screw 651, so that the connecting rod 65 can rotate around the screw 651, and the slider 66 is driven to move by the connecting rod 65. The top of the slider 66 is fixedly connected with a protrusion 661, and the inside of the movable plate 68 is penetrated by a movable groove 681. There are two movable grooves 681 symmetrically arranged, and the movable grooves 681 are in an inclined state. The distance between the two movable grooves 681 near the end of the workbench 3 is relatively large. The protrusion 661 is penetrated inside the movable groove 681, and the upper end of the protrusion 661 extends to the top of the movable groove 681. A column 69 is arranged on the side of the top of the movable plate 68 near the workbench 3. The upper end of the column 69 is connected to the limit plate 64. 6 moves to drive the protrusion 661 to move in the movable groove 681, so that the movable plate 68 moves forward and backward, thereby clamping the raw material. The limiting plate 64 includes a fixed plate 641 arranged on the top of the movable block 63 and the column 69. The interior of the fixed plate 641 is hollow. A return spring 642 is arranged inside the fixed plate 641. Multiple groups of return springs 642 can be arranged. The upper end of the return spring 642 is connected to the movable plate 643. The lower end of the movable plate 643 is slidably arranged inside the fixed plate 641. The movable plate 643 can be retracted into the fixed plate 641 under the compression of the pressing plate 5, without affecting the pressing of the pressing plate 5 on the raw material. At the same time, it is suitable for raw materials of various sizes to avoid the situation where the raw material is thick and the limiting plate 64 cannot limit the raw material.

[0024] Working principle: first, place the raw material to be pressed on the workbench 3, and control the rotation of the adjusting screw 61 through the motor 62. Because the threads on the outer walls of the two ends of the adjusting screw 61 are in a positive and negative tooth structure, the two ends of the adjusting screw 61 rotate in opposite directions, so that the movable block 63 moves in opposite directions and performs a centering movement, driving the limit plates 64 on the movable block 63 to approach the left and right sides of the raw material until the limit plates 64 are close to the raw material and fix the left and right sides of the raw material. At the same time, when the movable block 63 moves, it will drive the connecting rod 65 to push the slider 66 to move toward the middle on the guide rod 67, so that the two sliders 66 move relative to each other, and the protrusion 661 on the slider 66 moves obliquely in the movable groove 681, driving the movable plate 68 to approach the workbench 3. At this time, the limit plates 64 on the movable plate 68 approach and abut the front and back sides of the raw material, so as to limit the raw material around and prevent the raw material from sliding on the workbench 3. The hydraulic cylinder 4 controls the hydraulic telescopic rod 41 to push the pressing plate 5 downward, and the pressing plate 5 squeezes the raw material downward for pressing.
