Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] The structure of the double-point different-plane vibration incremental forming device of the present invention is as follows: figure 1 As shown, it includes clamps 2 and the sheet material 3 to be formed fixed between the clamps 2. A forming tool head 4 is arranged on one side of the sheet material 3, and an auxiliary tool head 6 is arranged on the other side. The forming tool head 4 and the auxiliary tool head 6 are respectively connected with The main shaft vibrating device 5 is connected, such as figure 2 As shown, the two sets of main shaft vibrating devices 5 respectively include a transmission shaft 55 connected to the bracket 1, and a collector ring 54 is arranged on the transmission shaft 55. The generator 7 is connected with the vibration signal generator 8, the transmission shaft 55 is connected with the transducer 51 thro...

The invention discloses a double-point different-face vibration incremental forming device which comprises clamps and a to-be-formed plate fixed between the clamps. A forming tool head is arranged on one side of the plate, an auxiliary tool head is arranged on the other side of the plate, the forming tool head and the auxiliary tool head are connected with a spindle vibration device respectively, and the spindle vibration device is connected with an electric signal generator and a vibration signal generator respectively and fixed on a support. By the double-point different-face vibration incremental forming device, during plate processing, when one tool head forms the surface, the other tool head supports the plate on the undersurface, so that the problem of being prone to causing defects like accumulation, wrinkling and breaking when a plate deforming in two directions is processed in the prior art is solved, forming limitation of the plate is improved, and resilience in the process of plate forming is reduced; during processing, continuous processing is converted into pulse-type processing by combining characteristics of vibration, so that processing accuracy is high, and processing quality is improved. The double-point different-face vibration incremental forming device has excellent process effect.
Description
technical field [0001] The invention belongs to the technical field of incremental forming, and in particular relates to a double-point different-plane vibration incremental forming device. Background technique [0002] With the rapid development of modern industry, the demand for sheet metal formed parts is increasing, and its shape is becoming more and more complex, especially in the fields of aerospace, automobiles, ships, etc., sheet metal formed parts occupy a pivotal position. The forming method of traditional sheet metal parts generally uses matching molds. The mold forming method has wide applicability, high production efficiency, and is suitable for mass production. It has occupied a dominant position for many years. Large, the size of the parts is limited by the size of the equipment, the production requires repeated mold trials, and the mold material and mold processing costs are relatively high. Therefore, the mold forming method is difficult to meet the require...
