Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 2, Figure 4 shows, the rotary turnover panel bender of one of the present utility model, comprise cope match-plate pattern 211 and lower bolster 221, lower bolster 221 is provided with support tray 222 and a bending tray 223, cope match-plate pattern 211 is provided with the pressing plate 212 of a corresponding supporting bracket block 222 and the folded block 213 of corresponding bending tray 223 position, pressing plate 212 is connected to cope match-plate pattern 211 with some binder spring 211a, and folded block 213 is rotationally connected with cope match-plate pattern 211.In actual processing, workpiece 3 is first located in and supports on tray 222, it treats that dogleg section is suspended on above bending tray 223, in matched moulds process, cope match-plate pattern 211 is descending, pressing plate 212 workpiece pressing 3 is positioned at the part supported on tray 222, along with the continuation of cope match-plate pattern 211 is descending, workpiece 3 can compress by pressing plate 212 under the effect of binder spring 211a, then folded block 213 touches the overhanging portion of workpiece 5, folded block 213 attaches the overhanging portion of workpiece 3 by the rotation of self, it is made to complete under the active force of bending tray 223 around axle bending, in this process, folded block 213 produces bending moment by the active force being scattered in workpiece 3 surface, very large pressure can not be produced to workpiece 3 surface, avoid because pressure concentrates workpiece 3 surface caused to have the problem of impression, improve product appearance quality.
As shown in Figure 3, four leads 23 through pressing plate 212 are provided with between cope match-plate pattern 211 and lower bolster 221.When this bender matched moulds, pressing plate 212 vertically can move under the restriction of lead 23, and what such pressing plate 212 and support tray 222 can be just right clamps workpiece 3, prevents workpiece 3 from both, relative sliding occurring again and causing scratch.
As shown in Figure 2, Figure 4 shows, cope match-plate pattern 211 is provided with a fixed block 214, fixed block 214 comprises and is fixed on first 2141 of cope match-plate pattern 211 and be exposed to second 2142 of cope match-plate pattern 2142, second 2142 for cross section be the arc column structure of major arc, folded block 213 has the accepting groove (mark) of collecting second 2142.Folded block 213 is coordinated by with fixed block 214 second 2142 of accepting groove, such folded block 213 is only around the free degree that second 2142 axis rotates, in design, second 2142 axis are parallel with the bending edges 2231 on bending tray 223, such folded block 213 whole process can be attached at workpiece 5 surface by workpiece 5 Forging Process, prevents workpiece 5 from distorting.
As shown in Figure 2, Figure 4 shows, clamp a returning spring 211b between folded block 213 and cope match-plate pattern 211, returning spring 211b is positioned at the side of fixed block 214 near pressing plate 212.If folded block 213 is connected on fixed block 214 loosely, its centre-of gravity shift may cause folded block 213 corner to touch workpiece 3 prior to pressing plate 212, this can cause workpiece 3 to locate the problem on failure and folded block 213 scratch workpiece 3 surface, it can be made to be returned to the state of folding surface 2131 all positon higher than pressing plate 212 when die sinking by the returning spring 211b inside folded block 213, the binder action of pressing plate 212 and the flexing movement of folding surface 2131 are carried out in order.
As shown in Figure 2, Figure 4 shows, folded block 213 has folding surface 2131, and folding surface 2131 is provided with a mat surface layer 213a.Because workpiece 3 is for axle rotates with bending edges 2231, and folded block 213 rotates centered by second 2142 axis, so in actual punching course, folding surface 2131 and workpiece 3 surface still there will be relative sliding, this adds increased the scratch risk on workpiece 3 surface; Above relative sliding can be avoided the damage on workpiece 3 surface by a softer mat surface layer 213a, ensure that product appearance is without scratch.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
