Problems solved by technology

[0005] There are many defects and deficiencies in the numerically controlled thermal progressive forming device adopted in the above-mentioned technical solution: On the one hand, during the processing of the magnesium alloy sheet metal, an external heat source needs to be used to heat the sheet blank, and the composition of the heating device is complicated; Very cumbersome and the effect is difficult to guarantee
In fact, this kind of lubrication method that manually brushes the lubricant on the board ingredients cannot effectively control the thickness of the lubricant film, and it is difficult to control the thickness of the lubricant according to the thickness of the board to be processed. The specific temperature (value) of each part is adjusted accordingly
In short, its actual lubrication effect cannot be effectively guaranteed
Moreover, once the lubricating oil is applied unevenly, there will be friction between the forming tool head and the plate blank with constant dry / wet changes and disorderly changes. Therefore, it is easy to cause scratches on the surface of the formed part and affect its surface processing quality; Moreover, since the temperature of the magnesium alloy surface cannot be reasonably controlled according to the temperature required by the processing technology during the working process of the processing tool head, this will inevitably affect the processing accuracy of the magnesium alloy sheet, reduce the quality level of the finished product, and even cause an increase in the scrap rate , which further affects the processing and manufacturing costs
[0007] Furthermore, this manual way of adding lubricating oil has low operating efficiency. During the processing, the operator's repeated operation of brushing lubricant will cause an increase in labor intensity, and second, direct contact with the lubricating oil agent for a long time , nor take advantage of the physical health of the operator

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] like figure 1 , figure 2 As shown, the rotary progressive forming device for magnesium alloy sheet metal tools of the present invention includes a frame and a forming tool head, and is characterized in that a lubricating oil spraying device is also arranged on the frame, and the lubricating oil spraying device is externally connected to the controller ; In the progressive forming process, the above-mentioned lubricating oil injection device is under the control of the controller 5, spraying lubricating oil towards the working end around the forming tool head, and forming a bubble-like oil film on the magnesium alloy plate blank.

[0035] The distance between the outlet end of the lubricating oil injection device and the working end of the forming tool head is greater than the radius of the bubble-like oil film.

[0036] The above-mentioned lubricating oil i...

Abstract

The invention discloses a tool rotating incremental forming device for a magnesium alloy sheet. The tool rotating incremental forming device for the magnesium alloy sheet comprises a rack and a forming tool head. The tool rotating incremental forming device for the magnesium alloy sheet is characterized in that the rack is further provided with a lubricating oil injecting device, and the lubricating oil injecting device is connected with a controller in an external mode; during the incremental forming process, and under the control of the controller, the lubricating oil injecting device injects lubricating oil to the periphery of the working end which surrounds the forming tool head, and a bubble-like oil film is formed on a magnesium alloy sheet blank. The tool rotating incremental forming device further controls the lubricating oil to reasonably mix and blend with air, and according to the temperature rising condition of a forming region, automatic control is automatically carried out on a lubricating oil injection time, an injection volume and a rate. The tool rotating incremental forming device for the magnesium alloy sheet has the advantages that the structure is simple, the layout is compact, during the incremental forming process, the lubrication on a working face is more scientific and reasonable, the improvement on the quality of incremental forming processing can be effectively promoted, the pollution on an operating environment is lowered, and the waste of the lubricating oil is reduced.

Description

technical field [0001] The invention relates to a progressive forming device, in particular to a rotary progressive forming device for magnesium alloy sheet metal tools. Background technique [0002] Magnesium alloy is the lightest metal structural material in engineering applications, and has the advantages of high specific strength, good electrical and thermal conductivity, electromagnetic shielding, and shock absorption. [0003] NC incremental forming technology is a rapid prototyping technology that uses sheet metal as the processing object. It has the advantages of moldless forming and short design and manufacturing time. [0004] Chinese patent application CN10134781013B discloses a numerically controlled thermal progressive forming method for magnesium alloy sheet metal and its heating device. The lubrication technology used in the processing process is to apply lubricant on the sheet blank, and resistance heating and heat radiation are required. Combined with adjus...
