    • PURPOSE:To improve the efficiency and safety of press work, by providing locator pins that conform with the reference hole of a work on the outer frame of an upper die and providing the fitting hole to the outer frame of a lower die and detaching the work by a member that interlocks with the upper die when the upper die comes to the limit of ascent. CONSTITUTION:Two locator pins 70 having conical tips 70a that conform with the reference hole 3 of work 2 are protruded downward on the outer frame 7a of an upper die 7, and fitting holes 71 of the pins 70 are provided on the outer frame 6a of a lower die 6. By this way, accurate press work is made possible even when there are some errors in accuracy of automatic feeding of the work. At the time of press work, remaining part 2' of the blanked work lowers by a length S from the upper face of the inner die 6b together with the outer frame of the lower die 6. Even when the upper die 7 goes up, the outer frame 6a does not go up. When a slide 5a arrives at the limit of ascent the outer frame 6a is pulled up through an outer frame pulling up bar 77 and a lever 78, and the work 2 is detached from the inner frame 6b. A blanked dial plate 1 is dropped from the upper die 7 and blown off by jetted air.
    • 目的:提高冲压加工的效率和安全性,通过提供符合上模外框上工件参考孔的定位销,并向下模的外框提供装配孔,并分离工件 当上模达到上限时,通过与上模相互锁定的构件。 构成:具有与工件2的基准孔3一致的锥形尖端70a的两个定位销70在上模7的外框架7a上向下突出,并且销70的装配孔71设置在外框架6a的外框架6a上 通过这种方式,即使当工件的自动进给的准确性存在一些误差时,也能够进行精确的冲压加工。 在冲压加工时,冲切加工的剩余部分2'与下模6的外框一起从内模6b的上表面下降长度S.即使上模7上升, 外框6a不上升。 当滑块5a达到上升极限时,外框架6a通过外框架拉杆77和杆78被拉起,并且工件2从内框架6b脱离。 冲裁的表盘1从上模具7下落并被喷射空气吹出。

    • PURPOSE:To execute easily and quckly notching and positioning operations of a plate material to be worked, by providing a positioning mechanism of the plate material to be worked, which consists of Y-axis and X-axis positioning mechanisms. CONSTITUTION:An X-axis moving block 3 is fixed, and positioning of a plate material to be worked 27 in the X-axis direction is executed. A Y-axis gauge unit 1 is moved to the designated size in the Y-axis direction of a plate material to be worked 37, and the Y-axis gauge unit 1 is fixed by turning a Y-axis clamp handle 25. An air cylinder 24 is operated by a dog 26 and a limit switch 27, a pair of Y-axis gauge plates 22 are closed in the X-axis direction along a Y-axis gauge plate supporting pin 21, and positioning in the Y-axis direction of the plate material to be worked 37 is executed. Thereafter, when the upper face of a punch 6 is pressed by the lower face of a ram of a press mechanism in a state that the side of the plate material 37 is butted to an X-axis gauge plate and the Y-axis gauge plate 22, the edge moves downward, and notching is executed in accordance with the designated size of X and Y axes of the plate material 37.
    • 目的:通过提供由Y轴和X轴定位机构组成的待加工板材的定位机构,执行待加工的板材的轻松,紧凑的切口和定位操作。 构成:X轴移动块3被固定,并且执行待加工的板材27在X轴方向上的定位。 Y轴测量单元1沿着待加工板材的Y轴方向移动到指定尺寸,Y轴测量单元1通过转动Y轴夹持手柄25而固定。空气 气缸24由狗26和限位开关27操作,一对Y轴测量板22沿着Y轴测量板支撑销21沿X轴方向封闭,并且在Y轴方向 执行待加工的板材37。 此后,当板材37的一侧与X轴测量板对接的状态下,冲压机构的压头的下表面被按压时,冲压机构的上表面被按压, 如图22所示,边缘向下移动,根据板材37的X轴和Y轴的指定尺寸执行切口。
