Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] like Figure 1 to Figure 5 As shown, a bending machine can be used to simultaneously bend multiple workpieces stacked from bottom to top, including a frame 1, on which there are sequentially arranged along the feeding direction of the workpieces into the bending machine. The first bending mechanism 2 that can bend the rear section of the workpiece, the second bending mechanism 3 that can bend the front section of the workpiece, and the workpiece positioning mechanism 4 that can position the workpiece before bending, such as Figure 16 to Figure 24 As shown, the workpiece positioning mechanism 4 is used to position multiple workpieces stacked from bottom to top before simultaneous bending. The positioning retaining surfaces 41 , each workpiece leans against different positioning retaining surfaces 41 to realize the positioning ...

The invention relates to a workpiece moving-out mechanism of a bending mechanism. The workpiece moving-out mechanism comprises a moving-out fixing frame, a moving-out sliding frame, a moving-out ascending and descending frame, a first clamp arm, a second clamp arm, a slide moving driving mechanism of the moving-out sliding frame, a slide moving guide mechanism of the moving-out sliding frame, an ascending and descending mechanism of the moving-out ascending and descending frame, an ascending and descending guide mechanism of the moving-out ascending and descending frame, a first clamp arm slide moving driving mechanism, a first clamp arm slide moving guide mechanism, a second clamp arm slide moving driving mechanism and a second clamp arm slide moving guide mechanism, wherein the first clamp arm slide moving driving mechanism drives the first clamp arm to slide and move along the first clamp arm slide moving guide mechanism so that the first clamp arm approaches to or leaves far away from the second clamp arm, and the second clamp arm clamp arm slide moving guide mechanism drives the second clamp arm to slide and move along the second clamp arm slide moving guide mechanism so that the second clamp arm approaches to or leaves far away from the first clamp arm. The workpiece moving-out mechanism of the bending mechanism disclosed by the invention has the advantages that the structure is simple, a bent workpiece is clamped through the first clamp arm and the second clamp arm, and in addition, the bent workpiece is output along the longitudinal direction, and the operation is convenient.
Description
technical field [0001] The present invention relates to a bending machine, in particular to a workpiece carrying-out mechanism of the bending machine for carrying out a bent workpiece. Background technique [0002] As a compact heat exchanger, the tube-fin heat exchanger has a wide range of applications in the refrigeration industry. The forming process of the heat exchanger mainly includes the following three forming processes: tube bending forming (forming U-shaped tubes), mechanical expanding tube forming (realizing tube-fin connection), tube bundle bending forming (forming L-shaped or U-shaped or G-shaped Heat Exchanger). Tube bundle bending is one of the key processes in heat exchanger forming, which has an important impact on the performance of heat exchangers. [0003] When the tube bundle is bent and formed, the heat exchanger is first transported to the specified position, so that the part to be bent is close to the bending die (roller) with a predetermined bendin...
