我厂生产的各类仪表的箱壳上有许多菱形散热孔。为此,我们设计制造了一付通用的冲菱形孔模具,配上机械、电气和气动的配合送料定位机构,实现了菱形散热孔的自动冲压。我们制造的通用冲菱形孔模,每冲次冲制两排,一排为九孔,一排为八孔。工件夹固在送料架上,送料架与负压气压筒的活塞杆相连,改变气压筒的进出气体方向来达到送料架往复动作的目的。级进距离由机械定位装置来保证,定位销由冲压行程触发微动开关控制继电器来抽拔。
I plant a variety of instruments produced on the box there are many diamond-shaped cooling holes. To this end, we have designed and manufactured a pair of common punched diamond-shaped hole tools, coupled with mechanical, electrical and pneumatic with the feed positioning mechanism to achieve a diamond-shaped cooling holes for automatic stamping. We create a common punched hole punch, punched two rows per stroke, a row of nine holes, a row of eight holes. The work piece is clamped on the feeding rack, the feeding rack is connected with the piston rod of the negative pressure barrel, and the direction of the gas in and out of the barrel is changed to achieve the purpose of the reciprocating action of the feeding rack. Progressive distance from the mechanical positioning device to ensure that the positioning pin by the stamping trip trigger micro switch control relay to pull.
