Problems solved by technology

The method of using molds for mass production will be limited, and the existing production methods of small sample parts such as: laser thermal stress forming, laser stamping forming, CNC forming hammer progressive forming, shot peening forming, multi-point forming, electromagnetic forming , NC incremental forming, etc. have shortcomings, and it is difficult to meet the requirements of production. It has become an urgent need in the field of plate parts production to develop a new technology and new equipment for plate processing suitable for rapid prototyping of small sample parts.

Embodiment 1

[0011] Embodiment 1: It is the processing of the plate in free state.

[0012] In this embodiment, a 1.5 mm thick copper plate is used. as attached figure 1 shown. The copper plate 1 is fixed around by the fixing device 2, and the middle is in a suspended state. The copper plate 1 and the fixing device 2 are fed together with the worktable at a certain speed and according to a predetermined path. The high-pressure water jet 3 acts on the surface of the copper plate, and the copper plate is deformed by the pressure of the water jet. The pressure and flow of the water jet can be adjusted to control the deformation of the copper plate perpendicular to the direction of the water jet. Cooperating with the movement of the worktable, the copper plate is processed into the desired shape. The working parameters adopted in this embodiment are: the working pressure of the high-pressure water jet is 35 MPa, the flow rate of the high-pressure water jet is 60 L / min, and the diameter of ...

Embodiment 2

[0013] Embodiment 2: for the processing of the plate when there is a half mold.

[0014] In this embodiment, a 1.0 mm thick steel plate is used. The surroundings of the steel plate are fixed with a blanking device, and the support mold half is placed under the steel plate, and the steel plate and the half-mold follow the workbench to move along the predetermined path at the same time, see the attached image 3 shown. The high-pressure water jet acts on the steel plate, and gradually presses the steel plate to the half-mold until the steel plate is close to the half-mold, and finally, the shape of the half-mold is the shape of the steel plate. The working parameters adopted in this embodiment are: the working pressure of the high-pressure water jet is 40 MPa, the flow rate of the high-pressure water jet is 60 L / min, and the diameter of the nozzle is Φ1.0 mm. See attached parts after processing Figure 4 shown.

Abstract

The invention relates to a water-jet asymptotic forming method of plates, which is the method for processing and forming the plates by utilizing high-pressure water jet and belongs to the mechanical engineering field. The invention can solve the forming problem of plates with small batch and multiple varieties and is characterized in that the high-pressure water jet with large flow is adopted and the high-pressure water jet, the pressure and the flow rate as well as the flow of which can be controlled is jetted to the surfaces of the plates through a nozzle of an injection device to form the plates; the plates are fixed on a working table and move along a preset deformation path under the control of a digital control device; the injection device moves up and down along the vertical direction so as to adjust the working range of the high-pressure water jet. Plates of arbitrary shapes can be formed by adopting the method.

Description

technical field [0001] The water-jet asymptotic forming of sheet metal is a set of methods for forming sheet metal by high-pressure water jet, which belongs to the field of mechanical engineering. Background technique [0002] Plate parts have the structural characteristics of thin shells. Because of their light weight, material saving, and smooth geometric shapes, they are widely used in civilian products, military products, and modern high-tech products, and their demand is gradually increasing. However, due to the rapid changes in the market environment, consumers' needs are becoming more subject-oriented, individualized and diversified, the speed of product replacement is accelerating, and customized production methods are gradually formed. The method of using molds for mass production will be limited, and the existing production methods of small sample parts such as: laser thermal stress forming, laser stamping forming, CNC forming hammer progressive forming, shot peeni...
