Description

Technical Field

[0001] The invention relates to the technical field of table top processing, and in particular to a hot bending processing method of a table top with an arc-shaped retaining edge and a table top manufactured by the method. Background Art

[0002] In recent years, ceramic rock slabs and other slabs have been widely used in surface decoration, bathroom, furniture countertops, furniture panels and other scenarios due to their large extension surface, strong texture plasticity and thin thickness.

[0003] In the existing application scenarios such as bathroom wash basins, cabinets, center islands, and bars, when people clean and wash the bathroom wash basins, water will inevitably splash onto the countertops and accumulate on the countertops, which requires frequent cleaning; or when using cabinets, center islands, and bars, items on the countertops are prone to fall to the ground if there is no edge guard on the outer periphery of the countertops, and cannot be repaired after being broken.

[0004] To this end, most existing countertop products usually have a rib designed on the outer periphery of the countertop. However, the existing countertop ribs and their processing still have the following defects:

[0005] 1. The existing retaining edge and countertop are usually split, that is, the retaining edge structure is glued and fixed to the outer periphery of the countertop by adhesive, or the retaining edge structure is locked and fixed to the outer periphery of the countertop by metal connecting fasteners, such as patent No. CN216920558U. The above-mentioned split water retaining structure is usually a right angle shape at the corner between the retaining edge and the countertop, leaving a rubber strip or a narrow gap, which is not convenient for cleaning and basically has a sanitary dead corner; and the design of metal accessories makes the overall countertop structure complicated, the installation is cumbersome, and the raw material cost and processing cost are high.

[0006] 2. A very small number of ribs are designed as one-piece with the countertop. The one-piece countertop ribs are usually made by pressure casting. Different specifications of pressure casting molds need to be customized according to the countertops of different specifications. The pressure casting mold is usually composed of at least two split upper and lower molds, such as patent number CN218091099U. However, the above solution can only solve the problem of hot bending and shaping of ceramic rock slabs with a specific large extension surface. However, there has been no good solution for the ceramic rock slab integrated basin, which has a small extension surface, a deep basin depth, and a partially sunken shape. The processing cost is extremely high, and it is not suitable for the processing and production of customized products with ribs set at specific locations such as single rib requirements.
