Description

Technical Field

[0001] The utility model belongs to the technical field of bending tooling, and particularly relates to a bending tooling for a board-end connector. Background Technique

[0002] Generally, a board-end connector is used for making electrical connection between two circuits, and is mostly divided into a board and a wire-end connector. In order to ensure that the board and the wire-end connector can be firmly fixed and not fall off after being connected, a bending tooling is required during the processing of the board-end connector to perform a bending operation on the pins on the board-end connector.

[0003] After retrieval, the patent publication number CN214321594U discloses a rectifier bridge pin bending device. The rectifier bridge pin bending device of the utility model, by arranging a lower pressing roller tangent to the top surface on the base, enables the pins to be bent flexibly and gently under the extrusion of the upper pressing roller of the pressing die and the lower pressing roller of the base, avoiding damage or destruction to the pin plating layer during the bending process, ensuring that the appearance of the pins after bending is regular and the strength is reliable; at the same time, because the stress at the pin bending part is evenly dispersed and the vibration is small during the bending process, the chip inside the rectifier bridge can be ensured to be safe, and the operation reliability of the rectifier bridge is improved. On the other hand, the utility model also considers the problem of bending error caused by the flipping of the rectifier bridge body during the bending process, and arranges a limit pressing plate for position constraint of the rectifier bridge to ensure the precise control of the pin bending angle.

[0004] When the existing bending tooling for board-end connectors is actually used, generally only the pins on one board-end connector can be bent, and this bending method has poor efficiency and is not easy to bend different models of board-end connectors. Therefore, we propose a bending tooling for board-end connectors to solve the existing problems. Content of the Utility Model

[0016] By means of the above technical solutions, the present utility model provides a bending tooling for a board-end connector, which has at least the following beneficial effects:

[0017] 1. Through the cooperation of a series of structures in the present utility model, when the staff performs a bending operation on the board-end connector, after placing multiple board-end connectors into the board-end connector placement grooves on the board-end connector placement plate and making the pins on the board-end connector located at the top of the bending table, the staff starts the hydraulic telescopic rod. The telescopic movement of the hydraulic telescopic rod will drive the moving plate to move in the X-axis direction. The movement of the moving plate in the X-axis direction will indirectly drive the bending table to move in the X-axis direction. After the staff makes the bending table in a certain position, the staff starts the electric push rod. The telescopic movement of the electric push rod will indirectly drive the fixed clamping plate and the bending upper roller to move in the Y-axis direction. When the staff makes the electric push rod drive the fixed clamping plate and the bending upper roller to move downward, the fixed clamping plate first contacts the pins on the board-end connector and fixes and clamps the pins. When the bending upper roller continues to move downward, it will bend the pins. Thus, the present utility model can simultaneously perform bending operations on the pins of multiple board-end connectors, improving the bending efficiency.

[0018] 2. Through the cooperation of structures such as the board-end connector placement plate, the fixed clamping plate, and the first mounting seat in the present utility model, since the fixed hanging ear is fixedly connected to the first mounting seat through the fastening bolt, the staff can replace the board-end connector placement plate to realize the bending operation on the pins of different models of board-end connectors, facilitating the staff to perform bending operations on the pins of different models of board-end connectors.

[0019] 3. Through the cooperation of structures such as the hydraulic telescopic rod, the moving plate, the slider, and the slide rail in the present utility model, when the hydraulic telescopic rod is started, the telescopic movement of the hydraulic telescopic rod will drive the moving plate to move in the X-axis direction. The movement of the moving plate in the X-axis direction will indirectly drive the bending table to move in the X-axis direction. The staff makes the bending table move to the position where the pins on the board-end connector need to be bent, thus facilitating the staff to perform bending operations at different positions of the pins on the board-end connector, further facilitating the staff to perform bending operations on the pins of the board-end connector, and having strong practicability.
