Description

Technical Field

[0001] The utility model relates to the technical field of hardware terminal processing, in particular to a positioning device for hardware terminal workpieces. Background Art

[0002] Hardware terminals are needed when connecting home appliance accessories. When the hardware terminals are produced and formed, they need to be bent, stretched, spun and other processes to finally complete the production of the hardware terminals. When bending the hardware terminals, bending molds are needed.

[0003] Most of the existing bending dies are of opposing type, which are formed by two dies being pressed and bent together. When bending, the collision of the dies will cause the dies to shift in position. At the same time, the collision will easily shift the unprocessed hardware, thereby reducing the bending quality and production quality of the hardware terminals.

[0004] Prior art CN214184913U is a terminal forming precision mold that sets the upper mold and the lower mold to be embedded. When bending the hardware terminal, the lower mold is embedded in the upper mold. The lower mold is fixed and positioned by the positioning slider, positioning column, positioning slot and positioning hole to prevent the position displacement caused by the collision between the lower mold and the upper mold. At the same time, under the action of the fixing block and the fixing slot, the end of the hardware terminal is clamped in the fixing slot to prevent the vibration caused by the collision between the lower mold and the upper mold from causing the hardware terminal to shift. The hardware terminal is firmly fixed in the lower mold, thereby solving the above technical problems. However, the above device is not suitable for hardware terminals of different models and has low applicability; therefore, it does not meet the existing needs. In this regard, we propose a positioning device for hardware terminal workpieces. Utility Model Content
