Double-inclined-wedge lateral punching die and punching method

Abstract

The invention relates to the field of punching dies and aims at providing a double-inclined-wedge lateral punching die and a punching method. The double-inclined-wedge lateral punching die comprises a lower die plate, a concave die, a convex die, a lateral compression block, an upper die plate, an air blowing pipe and a convex die resetting mechanism and a lateral compression block resetting mechanism, a punching die seat and a compression seat are arranged at the upper end of the lower die plate, the concave die is provided with a cutting edge hole and fixedly connected with the upper end of the punching die seat, the convex die is connected with the upper end of the punching die seat through a first sliding rail and provided with a punching head at the right end, the lateral compression block is connected with the upper end of the compression seat through a second sliding rail, a first inclined wedge, an upper compression head and a second inclined wedge are arranged at the lower end of the upper die plate, a first upper slope and a second upper slope are arranged at the lower ends of opposite side faces of the first inclined wedge and the second inclined wedge respectively, the convex die and the lateral compression block are provided with a first lower slope and a second lower slope respectively, and at least two pairs of guiding column guiding sleeves are arranged between the upper die plate and the lower die plate. The double-inclined-wedge lateral punching die is convenient to fix, and falling waste during punching is easy to clean and does not influence processing of subsequent workpieces.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a double oblique wedge lateral punching die and a punching method. Background technique [0002] The structure of punching die can be understood from the utility model of a kind of punching die disclosed by Chinese Patent Announcement No. CN201175936Y; Figure 4 And attached Figure 5 As shown, the sunroof guide rail 24 has a main board 241 and a fixing bar 242 parallel to the main board 241. There are four through holes 243 on the fixing bar 242. Due to the special positions of the four through holes, it is difficult to process the sunroof. Guide rail workpieces are punched from top to bottom, which is inconvenient to hold, and it is difficult to remove the washed-out waste, which affects the subsequent processing of the workpiece; therefore, it is necessary to design a double-slope that is easy to hold, and the washed-out waste is easy to remove without affecting the subsequent pro...
