Description
本發明係與沖床的平衡器有關，特別是指一種具自動調整平衡器的沖床。The invention relates to a balancer for a press, and in particular to a press with an automatic adjustment balancer.
參閱圖1所示，為現有一種具平衡器的沖床10，包含：機座11、一可上下往復移動地設置於該機座11之滑塊組12、一曲軸13、一連接該曲軸13與該滑塊組12的連桿14、及一動力連接該曲軸13的的驅動單元(圖上未示)。藉由該驅動單元帶動該曲軸13轉動，即可驅使該滑塊組12帶動該模具15上下往復移動進而對料件進行沖壓作業。Referring to FIG. 1 , there is a conventional press 10 with a balancer, comprising: a base 11 , a slider set 12 disposed on the base 11 and reciprocally movable, a crankshaft 13 , and a crankshaft 13 connected thereto. The connecting rod 14 of the slider set 12 and a driving unit (not shown) for electrically connecting the crankshaft 13. By driving the crankshaft 13 to rotate by the driving unit, the slider group 12 can be driven to move the mold 15 up and down to perform the pressing operation on the material.
一般而言，該連桿14上側設有橫向的通孔141，曲軸13穿過通孔141與連桿14轉動連接，為了減小摩擦力，連桿14的通孔141的孔壁上設有合銅16，連桿14通過合銅16與曲軸13接觸，由於滑塊組12等的重量關係，曲軸13與合銅16的下側的接觸面會存在一定的間隙，當有負載作用時，該間隙向下方移動而發生振動或雜音，為了避免上述情況，以及使滑塊組12、模具15、連桿14及曲軸13的重量平衡、使其運動平穩、圓滑，沖床還設有兩個平衡器17，兩個平衡器17分別設於機座11的左右兩側，常用的平衡器17為油壓缸或者氣壓缸，兩個平衡器17的桿體171的分別與滑塊組12的上側連接，通過平衡器17的拉力來克服滑塊組12、模具15、連桿14及負載的重力，使曲軸13與合銅16接觸平穩。Generally, the upper side of the connecting rod 14 is provided with a lateral through hole 141, and the crankshaft 13 is rotatably connected to the connecting rod 14 through the through hole 141. To reduce the frictional force, the through hole 141 of the connecting rod 14 is provided on the hole wall. The copper 16 and the connecting rod 14 are in contact with the crankshaft 13 by the copper joint 16. Due to the weight relationship of the slider group 12 and the like, there is a certain gap between the crankshaft 13 and the lower side of the copper alloy 16, and when there is a load, The gap moves downward to generate vibration or noise. In order to avoid the above situation, and to balance the weight of the slider group 12, the mold 15, the connecting rod 14 and the crankshaft 13, and to make the movement smooth and smooth, the press is also provided with two balances. The two balancers 17 are respectively disposed on the left and right sides of the base 11, and the common balancer 17 is a hydraulic cylinder or a pneumatic cylinder. The rods 171 of the two balancers 17 are respectively opposite to the upper side of the slider group 12. The connection, by the pulling force of the balancer 17, overcomes the gravity of the slider group 12, the mold 15, the connecting rod 14 and the load, so that the crankshaft 13 and the copper 16 are in smooth contact.
此外，沖床一般還設有沖床顯示幕(圖上未示)，用於顯示、設定沖床的各項運行參數，但這種沖床還存在以下不足之處：沖床調試人員是根據設計者提供的理論值估算滑塊組12、模具15、連桿14及曲軸13的重量來設定平衡器17的輸出，甚至有時候僅僅根據個人經驗及滑塊組12的運動情況自行設定調整平衡器17的輸出，理論估算的重量往往與實際有較大出入，而不同調試人員的個人經驗不同，往往設定值差別較大，而且更換模具15時，可能忘記要重新調整平衡器17的輸出或者由於經驗有限無法正確調整，上述幾種情況均可能會導致平衡器17的輸出設定不準確，會使合銅16與曲軸13的連接處局部強度負荷過重，使合銅16易磨耗；使合銅16與曲軸13局部間隙過小，導致發熱，甚至咬死現象；局部發熱會產生額外的能量消耗，使主電機的輸入功率不足，影響沖壓產品的精度。In addition, the punching machine usually has a punching screen (not shown) for displaying and setting various operating parameters of the punching machine, but the punching machine also has the following deficiencies: the punching machine is based on the theory provided by the designer. The values of the slider group 12, the mold 15, the link 14, and the crankshaft 13 are estimated to set the output of the balancer 17, and sometimes the output of the balancer 17 is set by itself based solely on personal experience and the movement of the slider group 12. The theoretically estimated weight tends to be different from the actual one, and the personal experience of different commissioning personnel is different. The setting value is often different, and when the mold 15 is replaced, it may be forgotten to readjust the output of the balancer 17 or it may not be correct due to limited experience. Adjustment, the above several conditions may lead to inaccurate output setting of the balancer 17, which will make the local strength load at the junction of the copper 16 and the crankshaft 13 too heavy, so that the copper 16 is easy to wear; the copper 16 and the crankshaft 13 are partially The gap is too small, resulting in heat and even seizure; local heating will generate additional energy consumption, making the input power of the main motor insufficient, affecting the stamping product Accuracy.

複參閱圖2所示，令該滑塊組22下端面設置有一具有第一重量的第一模具27，且令該驅動單元26帶動該曲軸24轉動時所產生的電流值為一電流標準值時，此時，該平衡單元30的桿體32在一第一位置，且當該平衡單元30的桿體32在第一位置時，令各該平衡單元30的拉力得以克服滑塊組22、第一模具27、連桿23及負載的重力，使曲軸24與合銅25接觸呈最為平穩的狀態。 Referring to FIG. 2, the lower end surface of the slider group 22 is provided with a first mold 27 having a first weight, and when the driving unit 26 drives the crankshaft 24 to rotate, the current value generated is a current standard value. At this time, the rod body 32 of the balance unit 30 is in a first position, and when the rod body 32 of the balance unit 30 is in the first position, the tension of each balance unit 30 is overcome by the slider group 22, The gravity of a mold 27, the connecting rod 23 and the load causes the crankshaft 24 to contact the copper 25 in the most stable state.
參閱圖3所示，當該滑塊組22下端面替換設置成第二模具28時，該第二模具28的第二重量與該第一模具27的第一重量不同，本實施例中以該第二模具28的第二重量大於(或小於)該第一模具27的第一重量為例，因此各該平衡單元30的桿體32下降(或上升)在第二位置(在此圖3故意誇示此第二位置，以容易了解)，同時，因該第二模具28的重量大於該第一模具27的重量，因此該驅動單元26帶動該曲軸24轉動時所產生的電流值為一電流異常值，此時，該壓力控制單元50接收到該電流異常值時，參閱圖4所示，該壓力控制單元50則控制該氣壓管路40內的壓力，使該平衡單元30的桿體32由第二位置上升(或下降)至第一位置，並保持在該第一位置處，藉以讓該曲軸24與合銅25的接觸效果保持在最佳最為平穩的狀態，達到沖床處於最佳工作狀態的目的。 As shown in FIG. 3, when the lower end surface of the slider group 22 is replaced by the second mold 28, the second weight of the second mold 28 is different from the first weight of the first mold 27, which is used in this embodiment. The second weight of the second mold 28 is greater than (or less than) the first weight of the first mold 27 as an example, so that the rods 32 of each of the balance units 30 are lowered (or raised) in the second position (in this case, FIG. 3 intentionally The second position is exaggerated for easy understanding. Meanwhile, since the weight of the second mold 28 is greater than the weight of the first mold 27, the current value generated when the driving unit 26 drives the crankshaft 24 to rotate is abnormal. The value, at this time, when the pressure control unit 50 receives the current abnormal value, referring to FIG. 4, the pressure control unit 50 controls the pressure in the air pressure line 40, so that the rod body 32 of the balancing unit 30 is The second position is raised (or lowered) to the first position and maintained at the first position, so that the contact effect between the crankshaft 24 and the copper 25 is maintained in an optimal and smooth state, and the punch is in an optimal working state. the goal of.
值得說明的是，該壓力控制單元50控制該氣壓管路40內的壓力，使該平衡單元30的桿體32由第二位置上升(或下降)至第一位置的位移量，主要是根據該驅動單元26帶動該曲軸24轉動時所產生的電流異常值與電流標準值之間的數值差異所決定。 It should be noted that the pressure control unit 50 controls the pressure in the air pressure line 40 to increase (or decrease) the displacement of the rod 32 of the balance unit 30 from the second position to the first position, mainly according to the The driving unit 26 drives the difference in value between the current abnormal value generated when the crankshaft 24 rotates and the current standard value.
綜上所述，本發明主要係由該驅動單元搭配該壓力控制單元，使得當該平衡單元的桿體在該第二位置時，該驅動單元能夠控制該氣壓管路內的壓力，使該平衡單元的桿體保持在該第一位置，讓該曲軸與合銅的接觸效果最佳最為平穩，達到沖床處於最佳工作狀態的目的，而上述實施例及圖式僅為本發明之較佳實施例而已，當不能以之限定本發明實施之範圍，舉凡依本發明申請專利範圍所作之均等變化與修飾，皆應屬本發明專利涵蓋之範圍內。In summary, the present invention mainly uses the driving unit to match the pressure control unit, so that when the rod body of the balancing unit is in the second position, the driving unit can control the pressure in the air pressure pipeline to make the balance. The rod body of the unit is maintained in the first position, so that the contact effect between the crankshaft and the copper is optimal and the smoothest, and the punching machine is in an optimal working state, and the above embodiments and drawings are only preferred embodiments of the present invention.
