Description

Novel underlying nonstandard wedge mechanism Technical Field The utility model relates to the technical field of stamping dies, in particular to a novel underlying nonstandard wedge mechanism. Background The development of the automobile industry is gradually growing, the application of the high-strength steel plate on the automobile body is wider and wider, the high-strength plate die is cold stamping process equipment which is rapidly developed in the manufacturing of electromechanical products in China, and the high-strength plate die is provided with shaping procedures due to the consideration of rebound of a finished piece, and the shaping is generally divided into positive shaping and side shaping, and the side shaping is completed through side shaping wedges. In actual production, for some parts with smaller volume, the complex molding requirement of a general automobile die structure is often required to be split into a plurality of procedures and a plurality of sets of dies to be completed, so that the production flow is long, the die is frequently switched, the problems of structural vibration, part abrasion and the like of the traditional die are easy to occur under the high-speed stamping working condition, the production beat is limited, the rejection rate is high, and the stamping cost is greatly increased. Disclosure of utility model The utility model aims to provide a novel underlying nonstandard wedge mechanism so as to solve the problems in the background art. In order to achieve the above purpose, the novel underlying non-standard wedge mechanism comprises an upper insert block and a lower driving block, wherein the upper insert block is arranged on an upper die, the lower driving block is arranged on a lower die, the contact surface of the upper insert block and the lower driving block is an inclined surface, the top end of the lower driving block is provided with a guide surface, a guide sliding seat is arranged on the guide surface, a forming sliding block is arranged at the top end of the guide sliding seat, a fixing plate is arranged at one end of the forming sliding block, which is far away from the guide sliding seat, a forming punch is arranged in the fixing plate, a second reset nitrogen spring is arranged at one side, which is far away from the upper insert block, of the bottom of the lower driving block, and a first reset nitrogen spring is arranged at one end, which is far away from the lower driving block, of the forming sliding block. As an improved technical scheme, the contact surface of the upper insert block and the lower drive block is 35-45 degrees. As an improved technical scheme, the guide sliding seat is internally provided with a guide sliding block, and the fixed plate is in sliding connection with the guide sliding seat through the guide sliding block. As an improved technical scheme, the forming punch is arranged on the fixed plate through a quick-release assembly. As an improved technical scheme, the elastic coefficients of the first return nitrogen spring and the second return nitrogen spring are adjustable. As an improved technical scheme, the contact surfaces of the upper insertion block and the lower driving block are provided with wear-resistant gaskets. After the technical scheme is adopted, the utility model has the beneficial effects that: According to the utility model, through the cooperation of the lower driving block and the forming sliding block, the vertical punching force transmitted by the upper inserting block is converted into the normal forming force, so that the forming sliding block can drive the forming punch to perform oblique forming action on the stamping part plate, the accuracy and consistency of the oblique forming of the stamping part plate are ensured, and then the quick and stable resetting action is realized through the second resetting nitrogen spring arranged on the lower driving block and the first resetting nitrogen spring arranged on the forming sliding block, so that the manual intervention is reduced, the automation degree is improved, the complex oblique forming can be completed by the whole equipment through single punching, the number of dies and the punching working procedure are effectively reduced, the production cost is reduced, and the method is suitable for batch production of complex parts in an automobile die.
