Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and examples. It should be understood that the following examples are intended to facilitate the understanding of the present invention, and have no limiting effect on it.

[0044] In this example, if figure 1 and 2 As shown, the present invention adopts a horizontal gantry mobile double-spindle structure, including a gantry frame, a motion system and a plate turning and clamping platform. Among them, the gantry includes a base 1, an upper beam 2, and two A-shaped columns 3 placed between them. For the convenience of description, the length direction of the base 1 is defined as the X direction, the width direction as the Z direction, and the height direction as the Y direction. In the X direction, two A-shaped columns 3 are respectively located at both ends of the base 1 along the X direction. Preferably, the upper beam 2 adopts a variable cross-section design, so that ...

Abstract

The invention discloses a large-size, high-rigidity, double-sided progressive forming machine tool, which includes a gantry frame, a motion system, and a plate turning and clamping platform. The motion system includes two motion mechanisms arranged symmetrically with respect to the XY plane, and each motion mechanism includes an X axis movement assembly, Y-axis movement assembly and Z-axis movement assembly; the Z-axis movement assembly drives the forming tool to move along the Z direction; the Y-axis movement assembly drives the Z-axis movement assembly to move along the Y direction; the X-axis movement assembly drives the Y-axis movement assembly to move along the Z direction; X-direction movement; the blank clamping platform includes a movable frame for clamping the sheet and a fixed frame for fixing the movable frame, the bottom edge of the movable frame is rotatably connected with the bottom edge of the fixed frame, so that the movable frame can Flip around the bottom edge of the cage. The invention has the characteristics of high rigidity, large forming range, convenient clamping and variable initial sheet size. According to the invention, large-size sheets, thick sheets and high-strength sheets can be formed.

Description

technical field [0001] The invention belongs to the field of numerical control progressive forming, in particular to a large-size, high-rigidity double-sided progressive forming machine tool capable of forming large-size thick plates. Background technique [0002] Double-sided progressive forming is a kind of forming tool that uses two ball heads, which are located on both sides of the sheet, one for forming and the other for local support. Part forming technology. Since the double-sided incremental forming does not need molds at all, and the forming accuracy is relatively high, it is suitable for small batch and personalized manufacturing, and has a wide application prospect. However, unlike the most basic single-point incremental forming, double-sided incremental forming requires dedicated forming equipment. At present, in the research of double-sided incremental forming technology at home and abroad, the most widely used is the series or parallel robot, but due to the f...
