Abstract
The invention discloses a three-dimensional curved-surface uniaxial flexible forming device using a variable-curvature roller. The three-dimensional curved-surface uniaxial flexible forming device consists of a working roller, a rubber pad, a rubber pad driving mechanism, working roller adjustment mechanisms, a working roller driving mechanism and a fixing stander, wherein the working roller can adjust the curvature through bending, and can be bent through a plurality of adjustment mechanisms mounted on the working roller. The rubber pad driving mechanism is used for driving the rubber pad, so that the rubber pad can translate. The working roller driving mechanism is arranged at one end or both ends of the working roller. According to the equipment, continuous deformation of a three-dimensional curved surface can be realized; compared with a conventional whole mold forming mode, the three-dimensional curved-surface uniaxial flexible forming device has the advantages that design, manufacturing and mold testing are not required; compared with a conventional rolling and bending forming mode, the three-dimensional curved-surface uniaxial flexible forming device has the advantages that both a single-curvature part and a double-curvature part can be formed, and the cost is reduced.
Description
Technical field
The application is the single-axle flexible roll bending equipment for Plastic Forming, belongs to mechanical engineering field.
Background technology
At present, Sheet metal forming is an important branch of processing manufacturing industry, and the production for key components and parts provides guarantee, and the curved-surface piece of processing is obtained for extensive use at a lot of industrial circles.For large batch of curved-surface piece, it is possible to adopt die forming, but the construction cycle length of mould, production cost are high；Product for small lot or single-piece, it is necessary to consider the economy of its processing, adaptability and motility, and tradition roll bending forming technique is suitable only for shaping single degree and bus is the part of straight line, such as the part such as cylinder, cone.Therefore the new Three-dimensional Sheet Metal flexible forming of research and development is proposed an urgent demand.
Summary of the invention
The purpose of the application there is provided a kind of three-dimension curved surface single-axle flexible forming device using variable curvature roller, it is made up of working roll, rubber blanket, rubber blanket driving mechanism, working roll guiding mechanism, working roll driving mechanism and fixed frame, working roll is stiff shaft, or Bowden cable, Bowden cable is variable curvature working roll flexible, adjustable, is provided with several height adjustable working roll guiding mechanisms on the work rolls.Working roll only one of which, it is possible to be drive roll, it is also possible to be driven voller.The end of the adjusting rod on working roll guiding mechanism is provided with the opening bearing for regulating working roll curvature and support works roller, and opening bearing can swing with the Curvature varying of flexible working roller.Working roll driving mechanism can be arranged on the one or both ends of working roll.Rubber blanket and rubber blanket driving mechanism, be divided into upper and lower two parts, is rubber blanket above, is fixed on by rubber blanket on the rubber blanket driving mechanism being located below, and periphery fastens with fixing plate, and rubber blanket driving mechanism can pass through motor and drive chain and gear drive.
Traditional roll bending technology is combined by the application with the punching press advantage of elastic fluid (polyurethane rubber), multi-point flexibly forming technique, adopt elastic fluid to be coated on roller bearing or be placed in appearance frame and sheet material is carried out roll forming, it is acted on continuous print distributed load at the regional area of blank, realizes by means of the continuous moving of profiled surface He the textured surface being coated with elastic fluid.And adopt flexible Bowden cable as working roll, increase some control point on the work rolls to control its contour shape, it is achieved three-dimensional curve generation.
The application is described in detail as follows below in conjunction with accompanying drawing:

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Use the three-dimension curved surface single-axle flexible forming device of variable curvature roller as it is shown in figure 1, be made up of working roll 1, rubber blanket 2, rubber blanket driving mechanism 8, working roll guiding mechanism 3, working roll driving mechanism and fixed frame 5.
Working roll 1 material can be stiff shaft, it is possible to for Bowden cable, if stiff shaft can realize single-curvature part forming, if Bowden cable can realize three-dimension curved surface part forming, it arranges the working roll guiding mechanism 3 of several adjustable displacements.
Rubber blanket 2 and rubber blanket driving mechanism 8, it is divided into upper and lower two parts, above for rubber blanket (polyurethane rubber block can be adopted), rubber blanket 2 is fixed on the rubber blanket driving mechanism 8 being located below, periphery fastens with fixing plate, namely limit with appearance frame 9 around rubber blanket 2, as shown in Figure 4.Rubber blanket driving mechanism 8 is conventional drive mechanism, for instance driven chain and gear drive by motor.
Working roll guiding mechanism 3, one end is opening bearing 7, and opening bearing 7 coordinates with working roll 1.The other end can control to adjust the length of bar 6 by machinery or digital control scheme, to realize the free convergent-divergent of opening bearing 7 end movement, such as Fig. 2, Fig. 4.
Working roll driving mechanism can be arranged on the one or both ends of working roll 1.If working roll 1 material can arrange one end for stiff shaft and drive, the other end is detachable, shapes with the cylindrical component realizing closing and takes out.If working roll 1 is Bowden cable, two ends can be set and drive, to improve the stability of roll bending process.Working roll driving mechanism is conventional drive mechanism.As it is shown on figure 3, to profile surface part 4, according to required sheet material shape, manually or digital control system control working roll guiding mechanism 3, change the length of adjusting rod 6, make opening bearing 7 pull or suppress working roll 1 to make its flexural deformation.Compensator can be provided with in working roll 1 one or both ends so that it is the retractable when adjusting shape, can fix after adjusting shape, it is prevented that axial and circumferential produce relative displacement.Working roll 1 rotates under working roll driving mechanism effect, a certain amount of to rubber blanket 2 with pressing at present, rubber blanket 2 moves horizontally under rubber blanket driving mechanism 8 acts on, workpiece is made to produce to vertically move, the displacement produced due to adjusting rod 6 is different, workpiece is made to be subject to different longitudinal forces, thus realizing part curve generating.
The application adopts single shaft roll bending technology cushion to replace roller, and what rely on during work is the plane motion of cushion.From the way of contact of workpiece Yu cushion, single-axle flexible roll bending process is equivalent to circular arc and plane contact, and roll bending process contact area is bigger, and distributed load is more uniform, and forming process is also more steady.
