Making process of wind-power blade main model

Abstract

The invention discloses a making process of a wind-power blade main model, which belongs to the technical field of wind-power blade molding. The process comprises the following steps of: 1) making a metal steel frame platform at the bottom; 2) laying a wood plate; 3) coating epoxy resin white carbon black filler on the surface of the wood plate, placing multiple EPS (Expandable Polystyrene) polystyrene solid foams according to the shape of the designed main model in a laminated way, and bonding and fixing the EPS polystyrene solid foams; 4) machining profiles of the EPS polystyrene solid foams; 5) pasting glass fiber reinforced plastic airtight layers on the machined profiles in the step 4); 6) detecting the vacuum degrees of the glass fiber reinforced plastic airtight layers; 7) uniformly spreading wood substituted epoxy resin layers on the surfaces of the glass fiber reinforced plastic airtight layers which satisfy the vacuum degree requirements, controlling the spreading thicknesses at about 15-35 mm and curing the wood substituted epoxy resin layers at normal temperature; and 8) machining the surfaces of the wood substituted epoxy resin layers; and then coating gel coat layers on the wood substituted epoxy resin layers and curing and molding the wood substituted epoxy resin layers to obtain the main model. The main model made by using the process disclosed by the invention has the advantages of high profile precision, easiness for construction operation, low making cost as well as contribution to promotion and application.

Description

technical field [0001] The invention relates to a manufacturing process of a master model, in particular to a manufacturing process of a wind power blade master model. It belongs to the technical field of wind power blade forming. Background technique [0002] The length of the main model of the wind power blade mold is more than 40 meters. There are two main production methods: the first method is to use the wooden section plate, that is, the main model of the blade is divided into multiple sections according to the length direction, and each Place the cross-section boards in order, lay wooden strips or boards on the cross-section boards, then paste the FRP airtight layer, and finally achieve the required mold master model by scraping the car putty; this production method is easy to operate, but The biggest defect is that the surface accuracy is not accurate, and at the same time, it cannot be produced in sections, which is not conducive to transportation. The second met...

Problems solved by technology

The processing profile of the second method is accurate, can be divided into sections, and is convenient for transportation, but the cost is relatively high, a large amount of steel is consumed, and there are many small square tubes of welded metal in the production process, which requires too high quality of employees. In addition, the production cycle is longer
