Forming die for inhibiting bending springback of plate and forming method of forming die

Abstract

The invention provides a forming die for restraining bending springback of a plate and a forming method of the forming die. The forming die comprises a male die assembly, a female die assembly and a springback compensation assembly. The second guide sleeve is connected with the first end of the second guide column in a matched mode, and the second end of the second guide column penetrates through the second spring through the insulating rubber sleeve to be connected with the edge pressing plate. The fixed end of the sliding block guide rail is fixedly connected with the installation end of the female die fixing plate, the sliding end of the sliding block guide rail is connected with the lower end of the female die sliding block, an inclined guide column is arranged in the female die sliding block, the female die push plate is connected with the female die bottom through a fixing shaft, and electrode through holes are formed in the female die base plate, the female die fixing plate, the female die bottom and the female die push plate. The first end of the electrode sequentially penetrates through the first spring and the interior of the elastic block to be connected with the electrode through hole, and the second end of the electrode is connected with an external power source. By means of the springback compensation assembly, in the bending machining process, the forming defects caused by the bending springback phenomenon to the plate are reduced, secondary machining is reduced, the production process is automatic, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plate material processing bending deformation, in particular to a forming die for suppressing plate material bending springback and a forming method thereof. Background technique [0002] Sheet metal forming technology occupies a very important position in aviation, aerospace, automobile, weapon and other industries. Taking aircraft manufacturing as an example, according to statistics, the number of plate parts accounts for 50% of the total number of aircraft parts, and the number exceeds 10,000 in fighter jets, more than 40,000 in bombers, and 60,000 in large transport aircraft and mainline airliners. Many, processing man-hours account for 20% of the whole machine. It can be seen that the manufacturing of sheet metal parts has a huge impact on various manufacturing industries. Especially the bending forming of high-strength sheet metal is an important issue in the research of modern manufacturing indus...

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention provides a forming die and its forming method for suppressing the bending and springback of the sheet metal. The bending deformation of the sheet metal is relatively small through the die push plate and the die slide block in the springback compensation assembly. Large parts are compensated and suppressed for springback, and the springback angle is plastically strengthened by electroplastic strengthening components to alleviate the bending and springback phenomenon of the plate, thereby greatly reducing the forming defects caused by the bending springback phenomenon on the plate, and improving the overall quality of the production line. work efficiency
