Detailed Description

The utility model provides a die positioning device, which comprises a base 1, wherein a die fixing area is arranged at the center of the base 1. The base 1 may be a rectangular metal base, and the base 1 needs to be fixed on a workbench of the punch press, so that a positioning hole 13 is formed in the base 1, and a fixing bolt is mounted on the positioning hole to fix the base 1 on the workbench of the punch press. The die fixing area is positioned in the center of the base 1, the die fixing area can be a round hole, and the die seat is arranged on the round hole.

The base 1 is provided with a transverse groove 2 in the X direction and a longitudinal groove 3 in the Y direction and a mounting groove 4; the transverse grooves 2 and the longitudinal grooves 3 are arranged vertically. The mold base is also generally rectangular and then a mold 16 is placed over the mold base. The transverse grooves 2 and the longitudinal grooves 3 are perpendicular to each other, and can abut against the rectangular die holder from two directions, so that the position of the die holder is determined, and when the position of the die holder is determined, the mounting position of the die mounted on the die holder is also naturally determined.

In order to be able to determine the position of the mould base, the transverse slot 2 and the longitudinal slot 3 of the utility model are provided with linear mechanisms 5; the push rod of the linear mechanism 5 is provided with a limiting block 6, namely the limiting block 6 can directly prop against the die seat to realize position determination. The linear mechanism 5 generally has a memory function, and multiple groups of data can be set, wherein each group of data comprises the moving displacement of the telescopic rods of the two linear mechanisms 5, namely, the final position of the limiting block 6 is controlled by controlling the working condition of a motor. Therefore, the linear mechanism 5 sets a plurality of sets of data, each set of data including the position of the stopper 6 in the X direction and the position of the stopper 6 in the Y direction, so that each set can form the mounting position of one die holder. Therefore, the utility model can set the installation position parameter of each die seat on the control panel of the linear mechanism 5 in advance, when a certain die seat needs to be replaced, the corresponding parameter of the die seat is directly selected, so that the limiting blocks 6 reach the corresponding positions, then the die seat is contacted with the two limiting blocks 6, and then the pneumatic clamp 8 is started to clamp the die seat.

The transverse groove 2, the longitudinal groove 3 and the mounting groove 4 are inverted T-shaped grooves, and the lower part of the limiting block 6 is provided with a guide part 7 matched with the inverted T-shaped grooves. The guide part of the utility model not only has the guiding function, but also can ensure that the stopper 6 and the like can move in the groove more smoothly, and has the limiting and fixing functions. For example, the guide part at the lower part of the limiting block 6 is in an inverted T shape and can be embedded into an inverted T-shaped groove, so that the limiting block 6 cannot be separated from the groove, and the limiting effect is realized. Meanwhile, the guiding part of the pneumatic clamp 8 can also prevent the pneumatic clamp 8 from slipping from the mounting groove 4, and the pneumatic clamp 8 can adjust the position in the horizontal direction, so that the pneumatic clamp 8 can be suitable for mould bases 15 with different sizes, but cannot move in the vertical direction, and the pneumatic clamp 8 is stably mounted in the mounting groove 4.
