A progressive forming tool with automatic lubrication function

Abstract

The invention relates to an incremental forming tool with an automatic lubrication function. The progressing forming tool with the automatic lubrication function comprises a gripping handle, an oil tank, a sealed bearing, a forming tool head, a gas pipe and a pressure controller; the forming tool head is mountedon a main shaft of an incremental forming machine tool, the upper end of the forming tool head penetrates through the oil tank, and the oil tank is connected with a fixed part of the incremental forming machine tool by connecting with the gripping handle; the sealed bearing is installedat the joint of the oil tank and the forming tool head, an oil groove is formed inside the forming tool head, an outlet of the oil groove is formed in the lower end of the forming tool head, and an inlet of the oil groove is connected with the oil tank. Compared with the prior art, the incremental forming tool with the automatic lubrication function has the advantages that automatic lubrication of the tool head and the sheet processing position during incremental forming is achieved,special lubricating oil adding equipment is no longer required, precise control over lubricating oil quantity inthe forming process is realized only by adjusting an input air pressure value,thus surface quality and processing efficiency of an incrementally-formed machined workpiece are improved, the labor costislowered, and the working environment is improved.

Description

technical field [0001] The invention relates to a tooling design for metal material plastic forming technology, in particular to a progressive forming tool with automatic lubrication function. Background technique [0002] Sheet metal numerical control incremental forming technology is a new type of flexible processing forming technology, which organically combines the concept of rapid prototyping and sheet metal plastic forming technology, and can be called the "3D printing" technology in the field of sheet metal forming. This technology does not need to use a mold or only needs a simple mold. The trajectory planning is performed in advance according to the three-dimensional model of the part to be formed. The general tool head finally obtains the required part under the control of the generated trajectory. During the forming process, the tool head moves in a rotating or non-rotating manner. Since the tool head is in sliding friction contact with the workpiece, it needs to ...

Problems solved by technology

However, if the amount of lubricating oil on the workpiece processing surface is too much, the temperature rise efficiency will be greatly reduced, and it will be difficult to reach the target temperature in the end.
