Description

Technical Field

[0001] The invention relates to the technical field of steam curing mat frames, in particular to a steam curing mat frame which can be freely adjusted according to temperature changes. Background Art

[0002] Existing steam curing pads are generally fixed structures and lack the ability to adapt to temperature changes. During the high-temperature steam curing stage in the autoclave, the temperature will quickly rise to 195°C and then quickly drop back to room temperature. Since these pads cannot adapt to temperature changes, they have the following major disadvantages:

[0003] Deformation caused by thermal expansion and contraction: Under high temperature, the cushion frame cannot adapt to the expansion of the material due to its lack of elasticity, which eventually leads to deformation of the cushion frame. This deformation not only affects its supporting capacity during the steaming process, but may also lead to reduced production efficiency.

[0004] Increased physical damage: When the fixed pad is cooled quickly, the unrelieved shrinkage pressure will cause increased structural stress and increase the risk of physical damage, thus affecting the service life and safety of the equipment.

The adjusting rod 3 is threadedly connected to the first threaded hole 11 and the second threaded hole respectively.

[0050] This embodiment also includes a third supporting structure 18 and a fourth supporting structure 19, which are arranged in parallel. The third supporting structure 18 and the fourth supporting structure 19 are both located between the first pad 1 and the second pad 2. The adjusting rod 3 passes through the third supporting structure 18 and the fourth supporting structure 19, and the adjusting rod 3 is threadedly connected to the third supporting structure 18 and the fourth supporting structure 19 respectively. The third supporting structure 18 is connected to the first pad 1, and there is a gap between the third supporting structure 18 and the second pad 2. The fourth supporting structure 19 is connected to the second pad 2, and there is a gap between the fourth supporting structure 19 and the first pad 1.

[0051] In this embodiment, the third supporting structure 18 and the fourth supporting structure 19 have the same structure. The third supporting structure 18 and the fourth supporting structure 19 both include a second bottom plate 20, a third web 21, a fourth web 22, a third wing plate 23 and a fourth wing plate 24. The third web 21 and the fourth web 22 extend from both ends of the second bottom plate 20 in the same direction, and the third web 21 and the fourth web 22 are both perpendicular to the second bottom plate 20. The end of the third web 21 away from the second bottom plate 20 extends the third wing plate 23 in the direction from the third web 21 to the fourth web 22. The fourth web 22 is away from the second bottom plate 20. A fourth wing plate 24 extends from one end of the plate 20 in the direction from the fourth web 22 to the third web 21. The third wing plate 23 and the fourth wing plate 24 are parallel to the second bottom plate 20, and there is a gap between the third wing plate 23 and the fourth wing plate 24.

The third wing plate 23 and the fourth wing plate 24 of the fourth supporting structure 19 are connected to the second pad 2, and there is a gap between the second bottom plate 20 of the fourth supporting structure 19 and the first pad 1. When thermal expansion and contraction or extrusion occurs, the third supporting structure 18 and the fourth supporting structure 19 can absorb deformation and reduce the impact of temperature changes and extrusion on the first pad 1 and the second pad 2.

[0052] In this embodiment, a third threaded hole 25 is opened on the third web 21 and the fourth web 22 of the third supporting structure 18, and a fourth threaded hole is opened on the third web 21 and the fourth web 22 of the fourth supporting structure 19, and the adjusting rod 3 is threadedly connected to the third threaded hole 25 and the fourth threaded hole respectively.

[0053] In this embodiment, the third supporting structure 18 and the fourth supporting structure 19 are arranged alternately, and the third supporting structure 18 and the fourth supporting structure 19 are arranged parallel to the first supporting structure 4 .

[0054] In this embodiment, the first support structure 4 and the third support structure 18 are alternately arranged, and the second support structure 5 and the fourth support structure 19 are alternately arranged. For example, between the first pad 1 and the second pad 2, the first support structure 4, the second support structure 5, the third support structure 18 and the fourth support structure 19 can be arranged as follows: the first support structure 4-the second support structure 5-the third support structure 18-the fourth support structure 19 structure-the first support structure 4-the second support structure 5-the third support structure 18-the fourth support structure 19 structure...

[0056] In this embodiment, both the Ω-shaped first supporting structure 4 and the second supporting structure 5 and the C-shaped third supporting structure 18 and the fourth supporting structure 19 are used, so that the overall structure has high strength, can effectively support the first pad 1 and the second pad 2, and can reduce the impact on the first pad 1 and the second pad 2 when the temperature changes and is subjected to external forces.

[0057] This embodiment also includes a first reinforcement structure 26 and a second reinforcement structure 27, which are angle steels.

The second reinforcement structure 27 is used for welding with the second pad 2, and there is a gap between the second reinforcement structure 27 and the first pad 1.

[0058] All structures of this embodiment are made of steel structure. When this embodiment enters the autoclave curing stage, the temperature in the autoclave will change from room temperature to 195 degrees and then to room temperature within 12 hours. The large temperature change will cause the object to expand and contract. When this embodiment is used at high temperature, the adjustment rod 3 extends, driving the first support structure 4, the second support structure 5, the third support structure 18 and the fourth support structure 19 to expand, and then driving the first pad 1 and the second pad 2 to expand. When the temperature drops, the adjustment rod 3 shrinks, and also drives the first support structure 4, the second support structure 5, the third support structure 18 and the fourth support structure 19 to shrink, and then drives the first pad 1 and the second pad 2 to shrink, that is, the adjustment rod 3 can release the expansion at high temperature, and the release amount can be recovered by adjusting the adjustment rod 3 during the cooling and shrinking process, thereby reducing the physical damage to the curing pad frame and extending the service life. In addition, if there is a curved part on the surface of the first pad 1 and the second pad 2, after the adjustment rod 3 is removed, the first pad 1 and the second pad 2 can be separated, which is convenient for repairing the curved part of the first pad 1 or the second pad 2.

[0059] The unique retractable structure formed by the adjusting rod 3, the first supporting structure 4, the second supporting structure 5, the third supporting structure 18 and the fourth supporting structure 19 in this embodiment can automatically adapt to temperature changes, effectively solve the problem of thermal expansion and contraction of materials in high temperature environments, and ensure the stability of the steam curing process. In this embodiment, the adjusting rod 3 is used to accurately control the telescopic range of the steam curing pad, allowing flexible adjustment during thermal expansion and cooling contraction, thereby reducing physical damage caused by temperature changes. In this embodiment, the service life is significantly extended, the frequency of maintenance and replacement is reduced, and the operating cost is reduced by reducing the impact of temperature changes on the steam curing pad. This embodiment is not limited to the fiber cement industry, and is also applicable to other industrial scenarios that need to withstand high temperatures and temperature fluctuations, increasing the market application value. This embodiment optimizes the entire steam curing process by improving the reliability and stability of the equipment, and ultimately improves production efficiency and product quality, so that the equipment can continue to operate stably under high temperature conditions. In the design of this embodiment, the selection of materials and structures takes into account the anti-fatigue performance under long-term high temperature use, and is more suitable for long-term industrial applications. The overall design of this embodiment takes into account the mechanical properties under high temperature environments, ensuring that the steam curing pad has good bearing capacity and stability in high temperature and variable working environments.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes.
