Description
Technical field
The locking positioning mechanism of using when the utility model relates to a kind of upper/lower die matched moulds, locking and detent mechanism for especially a kind of megawatt wind-power blade mould.
Background technology
Along with day by day closing on of the tradition energy depletion timetables such as coal, oil, natural gas, the development and utilization of wind energy more and more obtains people's attention, has become one of project of the tool business promotion prospect of energy field, and development at home and abroad at present rapidly.Present stage, the electric power of China formed, and wind-power electricity generation only accounts for 1% left and right, and the development and utilization of wind-force still has very large space, and almost each province has at the Wind Power Project of building or planning to build.According to foreign media, for the roof that replaces " freedom tower " of 1776 feet high that World Trade Organization's Shuangzi high building of collapsing in " 911 " attack of terrorism designs also will arrange wind-driven generator, wind-power electricity generation in the popular degree of the world today as can be seen here.Business Communications Company Inc.'s prediction, in the several years, large scale wind power machine market, the world will be with the rate increase of year 20% left and right from now on, and the rate of rise of China may be faster.
Need the corresponding mould product owing to manufacturing the large-scale composite material blade, the production technology general flow of large-scale blade is the good upper die and lower die of first die casting, then by structure glue, carries out bonding and bound edge enhancing inside and outside carrying out between the matched moulds seam.Easily produce dislocation in upper and lower mould matched moulds process, and due to the weight of upper die mold self, the weight that comprises former shell, steelframe and product, often easily make hydraulic turnover mechanism produce distortion, mould is occurred laterally or dislocation longitudinally, according to statistics, because the mould matched moulds is not in place, produce product rejection rate about 5% left and right, blade need to be repaired again, the situation of scrapping even occurs.Therefore in matched moulds, need mould itself to possess the mechanism of location and locking, guarantee that mould carries out matched moulds according to the size positions of design, guarantee that the blade product design meets the needs of design, guarantee that blade product matched moulds clearance control is in the manufacturing technique requirent scope.Along with the MW class blade is done larger and larger, the maximum blade of current domestic making surpasses 60m, and it is especially important that the location of mould and locking device seem.
As shown in Figure 1, existing mold-locked frock is to adopt airbag 2a and C type card 1a that upper die mold flange 3a and counterdie die flanging 4a are locked, function singleness operation inconvenience, need manual one blocks, waste time and energy, and, due to manually-operated, have no idea to guarantee that each C type card 1a locks together, manual operation is random large, causes quality accident because the blade mold matched moulds is not in place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, locking and detent mechanism for a kind of megawatt wind-power blade mould is provided, solve locking and orientation problem in the upper and lower mould matched moulds of mould process simple, convenient, efficiently, can, according to the matched moulds size positions of design, make the accurate matched moulds of upper die and lower die.
The technical scheme provided according to the utility model, locking and detent mechanism for described megawatt wind-power blade mould is characterized in that: comprise the contiguous block that is arranged on mold flange girder steel lower surface and the connection box that is arranged on bed die flange girder steel upper surface; The patrix ear handle is set on described contiguous block, and the two ends of patrix ear handle stretch out in the both side surface of contiguous block; In described connection box, hydraulic cylinder is installed, the piston rod of hydraulic cylinder is connected with connecting rod, and the two ends of connecting rod arrange respectively connector; Lower end and the connecting rod of described connector are fixed, and the middle part of connector arranges rotating shaft, and connector can be rotated centered by rotating shaft, and the upper end of connector is hook-shaped for what match with the patrix ear handle; Lower surface at described contiguous block arranges the patrix plush copper, the counterdie groove matched with the patrix plush copper in the upper surface setting of connecting rod.
Bottom at described connector arranges spring, and an end of spring withstands connector, and the other end of spring is fixed on connection box.
Described rotating shaft is arranged in the elongate slots on connector.
The utlity model has following advantage: (1) solves the problem of large-scale megawatt blade mold matched moulds locking and location simple, convenient, efficiently; (2) large-scale MW class length of blade is large, and matched moulds locking and anchor point are many, adopt locking described in the utility model and detent mechanism can automatically realize producing the mould matched moulds, do not need manually to remove to swing C type card and block one by one, save a large amount of manpowers, and reliable and stable; (3) the utility model is being realized matched moulds when location, and the location that can realize three directions laterally, vertically and the matched moulds thickness direction, has guaranteed that the profile of blade meets the requirement of design, and can control structure glue thick, has ensured product matched moulds quality.
The accompanying drawing explanation
The structural representation that Fig. 1 is mold-locked frock in prior art.
Fig. 2 is structural representation of the present utility model.
