In the present embodiment, guiding Zhi Gao mechanism is located at Zhi Gao district, and at least one group of corresponding setting of guiding Zhi Gao mechanism is beaten below plate 217 with the first counterdie, and at least one group of guiding Zhi Gao mechanism correspondence setting is beaten below plate 235 with the 2nd counterdie. The screw thread end of interior hexagonal screw 276 is fixed on the first counterdie and breaks plate 217 and/or the 2nd counterdie breaks plate 235, sleeve on it 274 breaks plate 217 through the first counterdie and/or the 2nd counterdie breaks plate 235 at the lower face supporting lower die holder 254, and the return spring 272 on it rest against the first counterdie and breaks plate 217 and/or the 2nd counterdie breaks plate 235.

During use, workpiece 50 is carried out the first step stretching by the first upper trimming die 15 and first lower punch part, the Stamping Area that workpiece 50 after the first step stretching is displaced between the 2nd upper trimming die 16 and the 2nd undershoot module, carries out the 2nd step by the 2nd upper trimming die 16 and the 2nd undershoot module to this workpiece 50 and stretches.

It is specially, the Stamping Area that straight aluminium workpiece 50 is placed between the first upper trimming die 15 and first lower punch part, and it is positioned on first lower punch 211. Upper mould piece presses down, and first, Stamping Area is squeezed, and T-shaped de-material pin 134 falls, and is supported on first lower punch 211 by de-material through hole 2135. Then, buffer zone 42 is squeezed, and de-material spring 132 and patrix spring 11 compress, buffer zone 42 Stepwize Shrink, until upper mold holder 185 is bonded to each other with the de-backboard 187 of patrix, then, the first upper trimming die 15 protrudes out to Stamping Area, and supports workpiece 50. Owing to material removing mechanism supports first lower punch 211, therefore, first lower punch 211 promotes the first counterdie spring 219 to press down, and makes bar 215 by the first counterdie and the first counterdie is broken plate 217 and pressed down return spring 272. First upper trimming die 15 and the coupling docking of first lower punch part, upper mould piece continues to fall, and presses down the first bearing ring 213. Until upper mould piece and lower module fit tightly, complete to close mould, complete the first step and stretch, workpiece 50 forms disk like.

Then, die sinking again, upper mould piece is moved, due to supporting of material removing mechanism, first lower punch 211 time-delay reset, time-delay reset effectively avoid Stamping Area to expand before the upper top of first lower punch 211 and the workpiece 50 that causes the first step to stretch produces extra deformation. So, Stamping Area and buffer zone 42 are first expanded, and patrix spring 11 resets, and the first upper trimming die 15 is reduced in the first through hole of patrix material discharging plate 189. Have the prerequisite in enough spaces in Stamping Area under, material removing mechanism just departs from first lower punch 211, first lower punch 211 is after losing pressing force, under the return spring 272 of guiding Zhi Gao mechanism and the lifting force effect of the first counterdie spring 219, first lower punch 211 moves, promotes and the workpiece 50 on it moves.

While realizing the first step stretching, the workpiece 50 that another is also completed the first step stretching by the 2nd upper trimming die 16 and the 2nd undershoot module carries out the 2nd step stretching, it is specially, complete the Stamping Area that the workpiece 50 of the first step stretching is placed between the 2nd upper trimming die 16 and the 2nd undershoot module, and it is positioned on the 2nd bearing ring 232 of the 2nd undershoot module. Upper mould piece presses down, and first, Stamping Area is squeezed, then the 2nd upper trimming die 16 and the coupling docking of the 2nd undershoot module, and the 2nd upper trimming die 16 supports the 2nd lower punch 231 by this workpiece 50, and location female ring 162 supports the 2nd bearing ring 232 by this workpiece 50. Upper mould piece continues to fall, and in the 2nd through hole of the 2nd upper trimming die 16 by compression the 2nd upper trimming die spring 164 indentation patrix material discharging plate 189, and then extrudes buffer zone 42 by the de-backboard 187 of contact patrix. In buffer zone 42 extruded while, the 2nd upper trimming die 16 promotes the 2nd bearing ring 232 and the 2nd lower punch 231 downward. 2nd bearing ring 232 is made bar 234 by the 2nd counterdie and is compressed the return spring 272 that the 2nd counterdie beats under plate 235 and compress, and in addition, the 2nd counterdie spring 236 also compresses, and is compressed to the limit, and location female ring 162 and location subring 233 agree with mutually, complete to close mould. Completing the first step to stretch, workpiece 50 forms loudspeaker lid.

Then, die sinking again, upper mould piece is moved, and each parts reset, and the 2nd upper trimming die 16 departs from workpiece 50.

Compared with prior art, material removing mechanism of the present utility model and non-the fixing of upper die holder are rigidly connected, but elastic movable supports, namely, in the process resetted after punching press, material removing mechanism also can not rise with upper die holder immediately, but after producing enough floating spaces between the first upper trimming die and first lower punch, material removing mechanism is just separated with first lower punch, thus before effectively avoiding Stamping Area to expand the upper top of first lower punch and the workpiece that causes the first step to stretch produces extra deformation. So, material removing mechanism makes the design of first lower punch time-delay reset, effectively guarantees that the apparent size precision of workpiece is in standard range.

The loudspeaker lid quality better that its punching press obtains, precision height, outward appearance reaches the requirement of client, substantially without mould trace without drawing scratch, right alignment, within profile tolerance reaches customer requirement 0.2MM, planeness reaches within customer requirement 0.1MM substantially, minimum size tolerance reaches �� 0.05MM, and after stretching, material thickness variation controls within 0.03MM.

The utility model is not limited to above-mentioned enforcement mode, if various change of the present utility model or modification are not departed from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model also is intended to comprise these change and modification.
