Description

Technical Field

[0001] The utility model relates to the technical field of laminated wood board processing equipment, in particular to a hot pressing device for producing electrical worker laminated wood boards. Background Technique

[0002] In the prior art, the insulating laminate is simply called the laminate. The insulating laminate is an integral body formed by laminating and hot pressing two or more layers of fibers or fabrics impregnated with resin. It can be in the shape of a board, a tube, a rod or other shapes. Laminated products can be processed into various insulating and structural parts, and are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment. Many transformer manufacturers at home and abroad have increasingly used electrical worker laminated wood materials in transformers to replace insulating materials such as epoxy glass cloth boards, epoxy cardboard boards, and laminated insulating cardboard boards, and are used to make insulating structural parts such as transformer insulating supports, coiled short coils, upper and lower yoke insulations, lead brackets, and upper and lower pad foot blocks. It has the advantages of moderate specific gravity, high mechanical strength, convenient vacuum drying, and easy machining. Its dielectric constant is close to that of transformer oil, and the insulation coordination is reasonable, and it can be used in transformer oil at 105°C for a long time. At present, during the production of electrical workers, multiple board layers need to be pressed together, and glue needs to be applied between the board layers during the pressing process. However, during the pressing process, the laminated wood board may shift, resulting in poor hot pressing effect. Moreover, the hot pressing structure usually directly abuts against the laminated wood board and does not have a buffer structure, resulting in easy rigid collision during the hot pressing process, causing damage to the laminated wood board and affecting its hot pressing effect.

[0003] The Chinese utility model patent with the application number 202221362495.9 discloses a hot pressing device for electrical worker laminated wood boards, including a frame, a base fixedly arranged on the frame, and an extrusion member fixedly connected to the frame. The extrusion member is arranged above the base. Two opposite side walls of the base are fixedly connected with first scraping plates, and the first scraping plates are arranged obliquely. The end of the first scraping plate close to the base is lower than the end of the first scraping plate far from the base. However, the structure of this hot pressing device for electrical worker laminated wood boards is relatively complex. It vertically squeezes and positions the laminated wood board through a vertically arranged cylinder, and cannot horizontally limit the laminated wood board. Moreover, its hot pressing structure directly abuts against the laminated wood board and does not have a buffer structure, resulting in easy rigid collision during the hot pressing process, causing damage to the laminated wood board and affecting its hot pressing effect.
