The utility model discloses a cooling assembly for thread machining of a pen container, which comprises a thread machining mechanism, an outer cover is arranged in the thread machining mechanism, a cooling assembly is arranged on the outer cover, the cooling assembly comprises a cooling seat and an adjusting part, a mounting area is formed in the middle of the adjusting part, the cooling seat is arranged in the mounting area, and a fixing part is arranged on the cooling seat. A threaded hole is formed in the middle of the fixing part, a bolt is arranged in the threaded hole, a through hole is formed in the cooling seat, the adjusting part is arranged in the through hole, and the bolt is rotated to push the adjusting part in the through hole. According to the cooling assembly for thread machining of the pen container, the adjusting part can be extruded by rotating the bolt, so that a hose for conveying cooling liquid is pressed through the adjusting part, the hose is stressed to deform, the inner diameter of the hose is reduced, the drainage speed of the cooling liquid is reduced, and a tapping tool is convenient to cool and lubricate; and the use amount of cooling liquid is saved, and adjustment is convenient.

The application relates to a light-weight concrete insulation board and a preparation method thereof, and belongs to the technical field of building insulation boards. The light-weight concrete insulation board is mainly prepared from the following components: cementing material 350-400 parts by weight, light-weight aggregate 71-81.5 parts by weight, additive 10-17.5 parts by weight, foaming agent 1.5-2.0 parts by weight, reinforcing fiber 0.8-1.2 parts by weight, silica sol 2-3 parts by weight and water 160-200 parts by weight. The light-weight concrete insulation board provided by the application can significantly improve the insulation performance on the basis of guaranteeing mechanical properties such as compressive strength, and can guarantee the anti-freezing performance of the insulation board under low-temperature conditions.
