Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pin cutting, in particular to a tool for cutting pins of externally expanded pins. Background Art
[0002] In order to adapt to different installation and fixing methods, the pins of the optical receiving and transmitting device need to be bent, such as bending into an L-shaped structure, or bending into an outward-expanding folded structure. After bending, the pins need to be cut to ensure that the ends of the pins are flush, so as to facilitate the welding of the pins. At present, when cutting the pins of the outward-expanding folded structure, in order to avoid affecting the structure of the pins, they are cut one by one, but this cutting method is inefficient. Utility Model Content
[0003] The utility model provides a tool for cutting pins of externally expanded pins, so as to solve the deficiencies of the above-mentioned prior art and the problem of low efficiency of the current method of cutting pins one by one, and has strong practicality.

[0005] A tool for cutting outward-expanding pins includes a base plate, a vertical plate is mounted on the base plate, a rotating cylinder is mounted on the vertical plate, a rotating disc is arranged at the rotating end of the rotating cylinder, a pair of convex plates are arranged on the outer periphery of the rotating disc, a connecting plate is hinged on the convex plate, a plurality of vertical rods are mounted on the base plate, a middle block is mounted on the vertical rod, two pairs of through holes are provided on the middle block, avoidance grooves are respectively provided at the upper and lower ends of the middle block, a movable plate is provided at the upper and lower ends of the vertical rod, a convex portion is provided on the movable plate, a connecting shaft is provided on the convex portion, the other end of the connecting plate is rotatably arranged on the connecting shaft, a cutter is provided on the inner wall of the movable plate, the inner side end of the cutter is a blade-shaped structure, and the cutter is directly opposite to the avoidance groove. Among them, the pins with an outward-expanding bending structure can be inserted into the middle block, and then the pins are constrained and limited to prevent the pins from being deformed during the cutting process. At the same time, a two-way cutting method is adopted during the cutting process, and this cutting method can improve the cutting efficiency.
[0006] Furthermore, a pair of notches are provided on the middle block, and the notches are connected to the through holes. The notches are provided to facilitate the dropping and discharge of the pins.
[0007] Furthermore, an arc plate is provided at the upper end of the notch, and the arc plate can prevent the cut pins from flying upwards.
[0008] Furthermore, a baffle is provided at the end of the arc-shaped plate to prevent the pins from flying outwards.
[0009] Furthermore, an overhanging block is provided on the outer wall of the middle block, and a pair of V-shaped plates are hinged at both ends of the overhanging block, one end of the V-shaped plate is provided with a side pressure plate, and the other end of the side pressure plate is provided with a card plate. A spring is installed on the outer wall of the overhanging block, and the other side of the spring acts on the V-shaped plate. The light receiving and transmitting device is positioned by the side pressure plate and the card plate to prevent the light receiving and transmitting device from moving during the cutting process, which may affect the cutting accuracy.
[0010] The advantages of the above technical solution are:
[0011] The utility model facilitates the cutting operation of the outward-expanded folded structure pins. During the cutting process, the cutting operation can be performed on each pin at the same time, thereby improving the cutting efficiency. The pins can also be constrained and limited, thereby avoiding problems such as deformation of the pins. BRIEF DESCRIPTION OF THE DRAWINGS
