[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a flip forming mold, including a mold body 1 and an upper mold plate 5 located above the mold body 1, a floating body 2 for placing a workpiece is arranged between the mold body 1 and the upper mold plate 5, a groove is arranged on the top of the mold body 1, and a slide groove for vertical sliding limit of the floating body 2 is opened in the groove, an elastic part for elastically supporting the floating body 2 is arranged in the slide groove, and a floating part for assisting the upper mold plate 5 to cooperate with the floating body 2 to complete two bending molding of the workpiece at one time when the upper mold plate 5 is pressed down is arranged in the top groove of the mold body 1.
[0024] The elastic part includes a nitrogen spring 8, which is fixedly embedded in the slide groove of the mold body 1, and the floating body 2 is fixed to the output end of the nitrogen spring 8. The nitrogen spring 8 is a prior art, which mainly elastically supports the floating body 2 by filling high-pressure nitrogen in the cylinder and continuously using the reaction force of the nitrogen as a spring.
[0025] The floating part includes a flip plate 3 and a tension spring 10 symmetrically distributed on both sides of the floating body 2. A connecting plate 4 is welded on the end face of the mold body 1. Two hexagon socket head screws 6 are penetrated through the connecting plate 4. The two hexagon socket head screws 6 are respectively threadedly connected to the two flip plates 3. The hexagon socket head screws 6 and the connecting plate 4 are clearance-matched. The template 5 is driven by the hydraulic lever to move vertically downward to apply pressure to the workpiece. The workpiece is subjected to the downward pressure of the upper template 5 and the reaction of the floating body 2 and the flip plate 3, and is bent once. In the process of the floating body 2 moving downward, the top shoulders of the floating body 2 exert pressure on the bottom feet of the flip plate 3, so that the flip plates 3 on both sides are flipped toward the floating body 2, and then the workpiece is bent for a second time under the downward pressure of the upper template 5 and the extrusion of the floating body 2 and the flip plates 3 on both sides.
[0026] like Figure 1 and Figure 4 As shown, the outer sides of the mold body 1 and the flip plate 3 are fixed with hanging rings 9. Figure 4 The upper end of the middle tension spring 10 and the outer lifting ring 9 of the flip plate 3 are in a detached state. In fact, the two ends of the tension spring 10 are respectively hooked on the mold body 1 and the lifting ring 9 of the flip plate 3. The upper mold plate 5 moves vertically upward under the drive of the hydraulic lever, and the floating body 2 pushes the workpiece up under the elastic action of the bottom nitrogen spring 8. At the same time, the flip plates 3 on both sides are flipped outwards under the action of the tension spring 10, so that the formed workpiece can be separated from the groove of the mold body 1.
[0027] Two hexagon socket head shoulder screws 7 are symmetrically arranged on both sides of the bottom of the floating body 2. The two hexagon socket head shoulder screws 7 penetrate the mold body 1 from top to bottom and are threadedly connected to the floating body 2 in the slide groove. The hexagon socket head shoulder screws 7 are clearance-matched with the floating body 2 to limit the up and down floating of the floating body 2 and ensure the movement stability of the floating body 2.
[0028] The working principle and use process of the utility model are as follows: when in use, the workpiece to be processed is placed on the floating body 2 in the groove, and the upper template 5 is driven by the hydraulic lever to move vertically downward to apply pressure to the workpiece. The workpiece is subjected to the downward pressure of the upper template 5 and the reaction of the floating body 2 and the flip plate 3 to perform a bending. When the floating body 2 moves downward, the top shoulders of the floating body 2 exert pressure on the bottom legs of the flip plate 3, so that the flip plates 3 on both sides are flipped toward the floating body 2, and then the workpiece is bent for a second time under the downward pressure of the upper template 5 and the extrusion of the floating body 2 and the flip plates 3 on both sides, thereby realizing the processing procedure of completing two bending and forming of the workpiece at one time;
[0029] When the molding is completed, the upper mold plate 5 moves vertically upward driven by the hydraulic lever, and the floating body 2 pushes the workpiece up under the elastic action of the bottom nitrogen spring 8. At the same time, the flip plates 3 on both sides flip outward under the action of the tension spring 10, so that the molded workpiece can be separated from the groove of the mold body 1.
