The air inlet of each heating area is communicated with the air outlet of an undependent heating wind machine, and the air outlet of each heating area is communicated with the air inlet of the heating wind machine. Temperature sensors are pre-embedded in the first female mould and the second female mould. The temperature sensors and the heating wind machine are connected with the power source and a temperature control device.
Description
Technical field
The utility model relates to a kind of making mould of production process of the MW class pneumatic equipment blades made of being made by fiberglass, especially a kind of MW class pneumatic equipment blades made former with heater.
Background technology
In traditional leaf production process, what heating system adopted is to blow hot-air along the airfoil surface of spreading layer or blade with high-power air blast in the process of the shop of blade layer, curing, regelate to realize.The defective of this heating system maximum is exactly a blade in the process of shop layer, curing, regelate, and it is inhomogeneous to be heated, and understands the intensity and the air dynamic behaviour that directly influence blade.Simultaneously owing to being open space, so the thermal loss of hot-air also is very big.
Summary of the invention
The technical problems to be solved in the utility model is: new heating means in a kind of pneumatic equipment blades made manufacturing process are provided, overcome that the improper blade that brings of heating means is heated inhomogeneous in the existing pneumatic equipment blades made manufacturing process in the process of shop layer, curing, regelate, the intensity and the air dynamic behaviour of blade have been influenced, and the thermal loss of hot-air is very big, the deficiency of work under bad environment.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of MW class pneumatic equipment blades made former with heater, former has first former and second former of mutual closure, first former and second former all comprise the mould that is concave shape and the support frame of supporting mould, described first former and second former have respectively and are resolved at least three independently heating regions continuously, and each heating region is equipped with air inlet and air outlet; The air inlet of each heating region communicates with the air outlet of the heating blower of a platform independent, air outlet communicates with the air inlet of this heating blower, and described heating blower is connected with power supply and temperature control equipment.
In order better to control the heating-up temperature of mould, be embedded with temperature sensor in described first former and the second former die body, temperature sensor is connected with power supply and temperature control equipment.
In order to make mould be heated soon, be heated evenly, described first former and the second former die body are embedded with heat-conducting piece,
In particular, described heat-conducting piece is an aluminium matter honeycomb, and the cellular areola of heat-conducting piece communicates with heating blower.
The beneficial effects of the utility model are that leaf production mould of the present utility model has changed traditional heating system, can make blade can realize uniform heating at different thickness places, has improved the performance of product; Simultaneously, reduced heat loss, saved the energy, improved operating efficiency, improved working environment, shortened the production cycle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. formers among the figure, 2. support frame, 3. heating region, 4. heating blower, 5. power supply and temperature control equipment, 6. temperature sensor, 7. heat-conducting piece.
The specific embodiment
The structure in the cross section, one place of first former of the present utility model as shown in Figure 1, because the primary structure of second former and first former is similar, do not repeat to draw, first former comprises the mould that is concave shape and the support frame 2 of supporting mould, first former has and is resolved at least three independently heating regions 3 continuously, because accompanying drawing 1 is the structure in cross section, a surperficial place, so this figure reaction is place's cross section structure of one of them heating region 3, heating region 3 is provided with air inlet and air outlet; The air inlet of a heating region 3 communicates with the air outlet of the heating blower 4 of a platform independent, air outlet communicates with the air inlet of this heating blower 4, and heating blower 4 is connected with power supply and temperature control equipment 5; Be embedded with temperature sensor 6 in the first former die body, temperature sensor 6 is connected with power supply and temperature control equipment 5; Be embedded with heat-conducting piece 7 at the first former die body; Heat-conducting piece 7 is an aluminium matter honeycomb, and the cellular areola of heat-conducting piece 7 communicates with heating blower.
Operation principle of the present utility model is such: the heating region 3 of sending into former 1 after heating blower 4 heats cold wind, be diffused into the surface of former 1 mould uniformly by the heat-conducting piece 7 of the aluminium matter honeycomb on the former 1, temperature sensor is pre-buried surface to former 1 when making former 1, temperature sensor 6 will record signal and be transported to power supply and temperature control equipment 5, regulate the rotating speed of heating blower 4 by power supply and temperature control equipment 5, in the process of spreading layer and curing, regelate, can be heated uniformly thereby reach whole blade.Whole former comprises that the temperature of each heating region 3 of first former and second former is by 5 controls of a power supply and temperature control equipment, the heating blower 4 of each heating region 3 is realized in parallel and chain, when the firing equipment of one of them heating region 3 broke down, the heating blower 4 of other heating region 3 can help it to finish the heating of this heating region 3.
Below temperature control requirement of the present utility model is further introduced again:
One, the maximum hot blast temperature of Yun Xuing is 90 ℃;
Two, mould should solidify 15 hours at least at 50 ℃, and observed temperature rise/reduce to 10 ℃/hour.
Three, in order to carry out regelate, mold temperature rises to 80 ℃, heat at least 10 hours, and observe temperature rise/reduce to 10 ℃/hour.
When four, regulating the needed temperature of mould, each heating region temperature realizes synchronous ascending, descending, heating-up temperature error range ± 3 ℃, and temperature controlling party mask has memory function, and the temperature sampling measuring intervals of TIME is about 10 minutes.
The main innovate point of this MW class pneumatic equipment blades made former heating system is:
One, mold heated is adopted the split type mode of heating of subregion, so just can make the heating of blade more even.
Two, adopt enclosed heat cycles.As shown in Figure 1, the air inlet of mould connects the air outlet of heater, the give a dinner for a visitor from afar air inlet of machine of the air outlet of mould.Can reduce the loss of heat like this.
Three, pre-buried temperature sensor is controlled the rotating speed of blower fan by switch board, by modes such as shutdown insulations, makes the homogeneous heating of whole blade.
