In order to ensure that the gap between the upper mold and the lower mold is within a reasonable range, multiple hook-type tensioning devices are usually used to tighten the upper mold and the lower mold, such as figure 1 and figure 2 As shown, the tensioning device includes a hook 3 and a stop rod 2, usually the hook 3 is arranged on the lower die 4, and the stop rod 2 is arranged on the upper die 1, and the hook 3 on the lower die 4 is in the tensioning process. Under the action of the oil cylinder 5, the limit rod 2 is hooked, and multiple hooks 3 are required to be tightened at the same time; Asynchronous phenomena are prone to occur, which on the one hand will lead to low manufacturing quality of the blades, and on the other hand, it is easy to cause damage to molds, oil cylinders 5 and other components, reducing the service life of these components

The invention provides a control system for a blade turning die and a tensioning device with the control system for the blade turning die. The control system for the blade turning die comprises an oil supply unit, a reversing valve, an oil tank and a plurality of oil cylinders, wherein the oil supply unit is connected with the reversing valve; pressure of hydraulic oil output by the oil supply unit is adjustable; and the reversing valve is connected with a plurality of oil cylinders and is used for controlling motion of the oil cylinders. Compared with the prior art, the control system for the blade turning die has the advantages that a hook type tensioning device can steadily and synchronously move during tensioning of an upper die and a lower die, and components such as the blade turning die and the oil cylinders can be stressed uniformly and have relatively small dynamic load; therefore, the control system for the blade turning die is favorable for improvement of the manufacturing quality of a blade; and moreover, the service life of relevant components in the blade turning die and the control system can be prolonged.
Description
technical field [0001] The invention relates to mechanical manufacturing technology, in particular to a control system for a blade turning mold. In addition, a tensioning device with a control system of the blade overturning mold is also proposed. Background technique [0002] At present, molds are used in the production process of spare parts for many mechanical products. Therefore, in the production process of these spare parts, whether the mold is used reasonably has a very important impact on the production quality and production cost of these spare parts; taking the production of blades of wind power generators as an example, due to the irregular shape of the blade turning mold, The blade turning mold usually includes an upper mold and a lower mold. When closing the mold, the gap between the upper mold and the lower mold should not exceed 4mm, and the mold closing process should be smooth and synchronous, otherwise the shape and performance of the blade will be adverse...
