Description

Technical Field

[0001] The utility model relates to the bending of connector terminals, in particular to a PIN bending machine. Background Art

[0002] In the prior art, the terminals are generally bent using a punching head of a punching mechanism. However, when the punching head punches the terminal, the instantaneous force is large, which can easily damage the coating on the terminal surface and affect the terminal performance.

[0003] In the prior art, there is also a method of bending the terminal by flipping the bending plate 90°, such as patents: CN201620749806.5 A connector terminal bending device and CN202110276574.1 A connector terminal rapid bending device. The structures are relatively complex, and it is difficult to ensure the stability of the connector during bending, resulting in poor bending effect. Utility Model Content

[0004] The utility model provides a PIN bending machine, aiming to solve the above problems.

[0005] A PIN bending machine, which includes a frame, a material base, and a bending plate, the material base is installed on the frame, and the bending plate is installed on the frame and located in front of the material base; a connector is placed on the material base, and its terminals fall on the end of the bending plate, and the bending plate flips backward 90° to bend the terminals of the connector; the PIN bending machine also includes a pressing block, the frame is fixedly connected to a column, and a slide is installed on the column, and the slide is connected to a driving mechanism A, and the driving mechanism A drives the slide to move up and down, and the pressing block is fixedly connected to the slide and moves up and down with the slide, and the pressing block is located above the material base; when the bending plate flips backward 90° to bend the terminals of the connector, the pressing block presses on the connector; the material base has two protrusions, and the two protrusions are located on the rear side of the connector placed on the material base, which are higher than the connector placed on the material base; when the pressing block presses on the connector, it also presses on the two protrusions.

[0006] The above technical solution is further refined as follows: a groove is provided on the material holder, which is an open groove running through both sides of the material holder, and two side blocks are provided therein; a connector is placed on the material holder, which is clamped between the two side blocks and the lower protrusion is embedded in the groove, effectively positioning the connector.

[0007] To further refine the above technology, the driving mechanism A is a cylinder.

[0008] The above technical solution is further refined. A turning frame is installed on the frame, and the turning frame is connected to the driving mechanism B. The driving mechanism B drives the turning frame to turn backward 90°. The bending plate is fixedly connected to the turning frame and turns backward 90° together with the turning frame; the column is located behind the turning frame, and a limiting block is fixedly connected to it. The limiting block extends forward for a section, constituting a 90° backward turning limit for the turning frame.

[0009] To further refine the above technical solution, the driving mechanism B is composed of a cylinder connected with a gear and a rack.

[0010] The above technical solution is further refined. The end of the bending plate is provided with a tooth groove for accommodating the terminal of the connector, and the tooth groove has a large opening and a small bottom.

[0011] The above technical solution is further refined. A support block supporting the end of the bending plate is fixedly connected to the material holder; the bending plate is suspended in the air and supported by the support block, which can effectively prevent its deformation.

[0012] The advantages of the present invention are reasonable design and simple structure. It adopts the design of a pressure block. When bending the connector terminal, the pressure block presses the connector and the two protrusions on the material seat. The pressure applied by the pressure block is dispersed to the two protrusions on the connector and the material seat (the force-bearing surfaces of the two protrusions on the material seat are on the upper side and the force-bearing surface of the connector is on the lower side). It can avoid damage to the connector due to excessive pressure and can effectively improve the stability of the connector. BRIEF DESCRIPTION OF THE DRAWINGS
