Description

Technical Field

[0001] This utility model belongs to the field of punching technology, and in particular relates to a punching fixture with positioning function. Background Technology

[0002] A connector generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals. The male and female terminals, when in contact, can transmit information or current, hence the name connector.

[0003] Drilling is a necessary step in connector housing production to form mounting holes, positioning holes, or heat dissipation holes. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. However, in the process of using existing stamping fixtures, the product is simply positioned by the groove structure of the carrier, which makes it easy for the material to shift due to operational reasons, resulting in stamping failure and affecting the product yield.

[0008] Furthermore, the guide groove is connected to the positioning groove, and the sliding plate is located on the side of the positioning groove.

[0009] Furthermore, the positioning groove contains a support member, which includes a support groove and a base plate. The support groove corresponds one-to-one with the stamping column and is fixed to the base plate. The support groove supports the product and prevents product deformation. At the same time, the support groove can collect the waste material from punching.

[0010] Furthermore, the depth of the positioning groove is equal to the sum of the height of the protrusion and the thickness of the base plate.

[0011] Furthermore, the end of the positioning post near the through hole is provided with a guide surface, and the guide surface gradually tilts towards the center of the positioning post along the direction in which the positioning post is inserted into the through hole.

[0012] Furthermore, the punching mechanism includes a punching cylinder that drives the punching column to press down. The punching cylinder is fixed to a fixed base, the fixed base is fixed to the carrier, and the push rod of the punching cylinder is connected to the punching plate.

[0013] Furthermore, the fixed base is provided with a guide sleeve, the stamping plate is connected to the guide rod, and the guide rod passes through the guide sleeve.

[0014] Furthermore, a limit block is installed on the upper surface of the carrier.

[0015] To elaborate further, the product is a connector, and when the plurality of protrusions are placed in the positioning groove, both ends of the connector are located above the carrier.

[0016] The beneficial effects of this utility model are at least as follows:

[0017] The positioning mechanism of this utility model includes a sliding plate, several positioning pins, and a positioning cylinder that drives the positioning pins to approach the product.
