High-pressure water jet plate incremental forming and cutting device

Abstract

The invention discloses a high-pressure water jet plate incremental forming and cutting device, which comprises a five shaft forming unit, a plate material fixture, a lower support mold, a trough, a base, an ultrahigh pressure water pump and a high pressure water nozzle, wherein the five shaft forming unit is mounted above the base; the plate material fixture is mounted in the trough; the lower support mold is mounted in the plate material fixture and is connected with the trough; the trough is fixed on the base; and the high pressure water nozzle is mounted at the tail end of the forming armof the five shaft forming unit and is connected with the ultrahigh pressure water pump through a high pressure pipe. In the utility model, the powerful impact force of water jet is used for carrying out incremental forming on the plate; moreover, the fine features of the plate can be formed and cut by controlling the pressure of the water jet and the thickness of the water jet; and the forming efficiency and quality are far higher than the forming efficiency and quality of the current incremental forming method. Besides, the incremental forming way does not need lubricant and does not cause pollution to the environment, thus being a clean plate forming way.

Description

technical field [0001] The invention relates to a device in the technical field of plate processing, in particular to a high-pressure water jet plate progressive forming and cutting device. Background technique [0002] Metal sheets are widely used in aviation, aerospace, automobile, shipbuilding and other manufacturing industries. The traditional sheet metal stamping forming method is suitable for mass production and processing, but for small batches, multi-variety and sample trial production processing, a new technology has emerged in recent years. A method for incremental forming of sheet metal. This method does not need to make a special stamping die for the product, has the characteristics of flexible processing methods, high forming limit, and low processing cost, and is especially suitable for the processing and production of small batches of metal sheets. [0003] The current incremental forming method mainly transmits the forming force through the hard contact betw...
