Description

Improved generation scratch prevention pendulum block mould

Technical Field

The utility model belongs to the technical field of die equipment, and particularly relates to an improved anti-scratch swing block die.

Background

The patch capacitor metal bracket is made of iron-nickel alloy, and is produced by pre-tinning a material strip, cleaning, stamping, cleaning, and packaging and delivering. At present, when producing, the area of contact of the pendulum block and the slotting tool of the existing mould is only small, so that the slotting tool is worn very fast, a larger gap is easy to generate, the bending angle is unstable, the stress point of the pendulum block is far away from the forming position, the forming force is insufficient, and the bending angle of the pendulum block is greatly influenced by the fluctuation of the bottom dead center of the punch. The angle deviation is 3 degrees, and the product requires a bending angle tolerance of 0 to-2 degrees, so that the yield of the product is lower in mass production, the iron-nickel alloy pre-tinning material belt is high in price, and the profit of the product is far from expectations. For this reason, a "high-stability and long-life pendulum block mold" of patent No. ZL201822193992.0 is proposed.

However, in the process of using the die for a long time in my name, other defects of the die are found, such as: the slotting tool is assembled on the upper clamping plate and fixed by the screw and the pressing plate, the swinging block base is assembled on the stripper plate and is precisely limited by the hanging table to prevent the swinging block from moving up and down, and the swinging block is connected with the swinging block base through a hinge and is limited by the front and back movement of the cavity hole of the template. 2. When the sliding block descends to drive the upper die of the die to move downwards to remove the material plate to contact the lower die plate, the swing block base compresses materials, the upper die continues to descend to contact the swing block to push the swing block to swing towards the middle, the materials are pushed to bend to the lower dead point of the sliding block, after bending is completed, the sliding block of the punching machine drives the upper die to ascend, the slotting tool ascends to leave the swing block, and the problem that the angle of a product is unstable due to the fact that the slotting tool is not in place caused by the drift of the lower dead point of the punching machine easily occurs in the mode.
