Embodiment Construction

[0042] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0043] Such as figure 1 As shown, it is the top cover of the outdoor machine in the embodiment of the present invention, which is characterized by a rectangular drawn part with closed surroundings. figure 2 It is a cross-sectional view of the product, as shown in the figure, the bending of the inner buckle is designed for this product. To complete the bending at this place, it is necessary to bend the workpiece at the transition angle first, and then complete the final bending. The specific bending process is as follows: image 3 shown. When bending transition corners, it is a typical side bend. The lateral bending device of the present invention is used for the lateral bending. The lateral bending device of the present invention wil...

Abstract

The lateral bending device of the present invention relates to a bending device, and its purpose is to provide a lateral bending device in which both the bending die and the bending punch can move horizontally, the bending negative angle is large, and the mold can be demolded smoothly. device. It includes an upper mold, a lower mold, and a lateral bending mechanism. The lateral bending mechanism includes an upper mold wedge, a slider and a lateral die; one end of the slider is fixed with a lateral punch, and the other end is fixed with a push block; The slider can slide along the lower mold by connecting with the first elastic reset mechanism; the lateral die can slide along the slider by connecting with the second elastic reset mechanism; one end of the lateral die cooperates with the lateral punch to In bending, the other end and the push block form a gap; in the split state, there is a gap between the lateral punch and the inner surface of the workpiece side; in the closed state, the upper die wedge is inserted into the gap, so that the slider Sliding drives the lateral punch to abut against the side of the workpiece, and makes the lateral die move in the opposite direction of sliding relative to the slider, and cooperates with the lateral punch to bend the side of the workpiece.

Description

technical field [0001] The invention relates to a bending device, in particular to a lateral bending device. Background technique [0002] The top cover of the outdoor unit of the air conditioner is a rectangular drawn part closed all around. In order to ensure the contact strength between the top cover and the front panel of the outdoor unit of the air conditioner and prevent the top cover from collapsing under pressure, the top cover of the outdoor unit of the air conditioner is designed to be inward. bend. To process an inwardly bent shape, side bending is required. The bending die moves laterally and horizontally to fold the sheet side to the inside of the rectangular part. At this time, the sheet will wrap the punch located inside the rectangular top cover, and the product cannot be taken out when the mold is opened. [0003] In addition, a bending die is disclosed in the Chinese patent "A sheet metal bending die" (publication number CN203972634U). The bending die ca...
