Description
本發明是關於一種沖壓模組，特別是關於一種沖壓模組的故障偵測裝置及其偵測方法。The invention relates to a stamping module, in particular to a fault detecting device for a stamping module and a detecting method thereof.
沖壓製程是藉由一沖壓模具重擊材料，以對材料裁切、彎曲或塑造成所需之形狀，但由於沖壓製程中使用者較難直接以肉眼觀察沖壓模具的使用狀況，一般會以定期保養的方式來避免沖壓模具在沖壓過程中發生故障，因此，習知之沖壓製程並不易即時地在發生故障的當下得知故障已經發生，進而立即進行故障排除，造成沖壓過程中材料成形瑕疵，例如在製程中沖頭斷裂時，製程仍會不停的產出不良品，而降低了製程的良率，更甚至致使整體沖壓模具損壞。The stamping process is to punch the material by a stamping die to cut, bend or shape the material into a desired shape. However, it is difficult for the user to directly observe the use condition of the stamping die directly by the naked eye in the stamping process. Maintenance method to avoid the failure of the stamping die during the stamping process. Therefore, the conventional stamping process is not easy to immediately know that the fault has occurred in the event of a fault, and immediately eliminate the fault, resulting in material forming during the stamping process, for example When the punch breaks during the process, the process will continue to produce defective products, which will reduce the yield of the process and even cause damage to the overall stamping die.
此外，若該沖壓模具為連續模，且其中一道次之沖頭在沖壓製程中發生斷裂時，斷裂的沖頭可能掉入其他道次的模穴中，造成其他道次之沖頭因干涉而損壞。又或是其中一道次之沖頭斷裂時，使得材料在該道次所應產生的沖壓形狀並未產生，導致在下一道次中被沖壓之材料無法向外流動，進而造成沖頭的負荷過高，而再次地發生沖頭的斷裂。In addition, if the stamping die is a continuous die, and one of the punches breaks during the stamping process, the broken punch may fall into the other cavity, causing the punch of the other passes to interfere. damage. Or when one of the punches breaks, the stamping shape that the material should produce in the pass does not occur, resulting in the material being punched in the next pass cannot flow outward, which causes the load of the punch to be too high. And the break of the punch occurs again.

請參閱第1及3圖，於步驟14中該控制模組330接收該故障偵測裝置300輸出之該偵測訊號，且該控制模組330根據該偵測訊號判斷該沖壓模具200是否發生故障。其中，該沖頭220在沖壓過程中若有確實地沖擊該料帶400，該偵測器310所偵測到該偵測訊號的峰值會超過一設定值，該設定值小於該正常峰值(請參閱第7圖)，因此，在本實施例中，該控制模組330接收該偵測器310輸出之該偵測訊號後，是根據該偵測訊號的峰值是否超過該設定值判斷該沖壓模具200是否發生故障。 Referring to FIG. 1 and FIG. 3, the control module 330 receives the detection signal outputted by the fault detection device 300 in step 14, and the control module 330 determines whether the stamping die 200 is faulty according to the detection signal. . Wherein, if the punch 220 positively impacts the strip 400 during the stamping process, the detector 310 detects that the peak value of the detection signal exceeds a set value, and the set value is less than the normal peak value (please Referring to FIG. 7 , therefore, in the embodiment, after receiving the detection signal output by the detector 310 , the control module 330 determines whether the stamping die is determined according to whether the peak value of the detecting signal exceeds the set value. 200 has failed.
相對地，於步驟14中若該該控制模組330接收該偵測器310輸出之該偵測訊號的峰值並未超過該設定值時，則可能代表該沖頭220在沖壓過程中並未確實地沖擊該料帶400，更甚至代表該沖頭220於前一次的沖擊中斷裂，而導致此次的沖壓中該沖頭220並未沖擊該料帶400，因此，該控制模組330判斷該沖壓模具200發生故障，且該控制模組330發出一故障訊號至驅動該沖壓模具200之沖床，以停止該沖壓模具200之沖壓加工，避免產生後續的問題。 In contrast, if the control module 330 receives the peak value of the detection signal output by the detector 310 in step 14 and does not exceed the set value, it may represent that the punch 220 is not in the process of punching. Impacting the strip 400, and even representing the punch 220 breaking during the previous impact, the punch 220 does not impact the strip 400 during the stamping, so the control module 330 determines that The stamping die 200 fails, and the control module 330 sends a fault signal to the punch that drives the stamping die 200 to stop the stamping process of the stamping die 200, thereby avoiding subsequent problems.
請參閱第8圖，第8圖顯示該沖壓模具200對該料帶400進行沖壓加工而沖頭故障時，相對沖床曲柄角度，該偵測器310所測得之偵測訊號(聲壓訊號)。當沖頭220發生故障時(因超過沖頭本身材料極限強度而斷裂)，該沖頭220沖擊該料帶400所產的生聲波或振波的峰值一定會大於正常沖壓時所產生的該正常峰值(第8圖虛線部份所示之偵測訊號)。因此，於另一種實施方式中，步驟14之該控制模組330是根據該偵測訊號的峰值是否超過一設定值判斷該沖壓模具200是否發生故障，該設定值大於該正常峰值。當該控制模組330接收該偵測器310輸出之該偵測訊號超過該設定值，該控制模組330判斷該沖壓模具200發生故障，且該控制模組330發出一故障訊號至驅動該沖壓模具200之沖床，以停止該沖壓模具200之沖壓加工，避免產生後續的問題。 Please refer to FIG. 8. FIG. 8 is a view showing the detection signal (sound pressure signal) measured by the detector 310 when the punching tool 200 performs press processing on the tape 400 and the punch is faulty. . When the punch 220 fails (because it exceeds the ultimate strength of the material of the punch itself), the peak of the acoustic wave or vibration generated by the punch 220 impacting the strip 400 must be greater than the normal generated during normal stamping. Peak (detection signal shown in the dotted line in Figure 8). Therefore, in another embodiment, the control module 330 of the step 14 determines whether the stamping die 200 has a fault according to whether the peak value of the detecting signal exceeds a set value, and the set value is greater than the normal peak value. When the control module 330 receives the detection signal output by the detector 310 exceeding the set value, the control module 330 determines that the stamping die 200 is faulty, and the control module 330 sends a fault signal to drive the stamping. The punch of the die 200 is used to stop the stamping process of the stamping die 200 to avoid subsequent problems.
