[Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. Referring to Figs. 5 and 6, the preferred embodiment of the new screw head forming mold 2 is for forming a screw hole 41 from a screw head of a screw 4. The screw head forming die 2 includes a cylindrical punching body 21 whose bottom end surface has a concave arc shape, and a punch unit 22 protrudingly disposed on the bottom end surface of the punching body 21. The punch unit 22 has punch columns 221 standing upright on the bottom end surface of the punching body 21 and having a substantially square cross-sectional area, and is arranged on the peripheral surface of four punch columns 221 at equal angular intervals and along the punch column 22丨 The wing blocks 222 extending in the length direction, four spiked wings 223 which are alternately arranged between the four wing blocks 222 and whose top edges are connected to the bottom end face of the stamping body 21, and two are respectively symmetrical from the top of the two wing blocks 222 to the top. The ribs 224 extending horizontally and outwardly away from the punching column 221 and top, bottom, and bottom of the main body 21 are punched. Each wing block is an approximately right-angled triangle, that is, the top edge of the wing & 222 is the bottom end face of the punching body, and its outer edge is diagonally inward from the outside of the top edge and away from the bottom end face of the punching body 21. Extend downward to the bottom end of the punching post 221. The length of each of the spike wings 223 is about one-half of the length of the punching post 221, which is M266994. With the square pillar-shaped Chonggui 221 as the transfer center, the two ribs 224 are extended outwardly and arranged in a zigzag shape, the four-winged cymbals 222 and the four protruding spine wings 223 are respectively extended outwardly and arranged in a cross-shaped manner. The four-wing block is arranged in a rice-shaped shape in cooperation with the four-barbed thorn wing 223 of the child.

The screw and 4 can be universally used _-shaped screwdriver + sub-shaped screwdriver, square-shaped screwdriver and m-shaped screwdriver. Therefore, the screw head The forming mold 2 can really play out in actual use. 1. The formed screw 4 can be used in a variety of ways with various screwdrivers (such as ·······················), and the use is convenient ·· —Using the four-wing block 222 and the four-spike thorn wings 223 to arrange a composite geometric shape of a cross shape and a m-shape, with the punch 221 being a square shape, and the two ribs 224 being arranged in a line shape, so as to be formed by stamping The result: the wire 4 can be universally used for-type, cross, square and m-shaped screwdrivers. 'Screw 4 and screwdrivers are very easy to use and match.' It is also helpful to improve the cooperation of the screw 4 locks. Industry smoothness, improving conventional screw head forming dies The screw 3 formed by 1 is only used for flat, cross and square screwdrivers (see picture !, 2), or another well-known M-shaped screw master forming mold 5. The formed screw 7 can only be used for M-shaped screws. Type screwdriver use (see Figure 3 4) 'Both of them lack this problem in terms of convenience. M266994 2 · Effective in saving molding costs: Furthermore, the four-wing block 222, the four-spike wing 223 and the two ribs are used. 224 uses the punch 221 as the center and is arranged in a composite geometric shape of a letter shape, a cross shape, a square shape and a m shape, and the screw 4 having the composite shape screw hole 41 can be universally used by punching. Slotted screwdrivers, square and square-shaped screwdrivers are used. In this way, it only costs an early molding cost, which is relatively low in manufacturing costs. It effectively improves the screw head forming mold i (see Figure 丨), meters. Shaped screw head forming molds 5 (see Figure 2), and even straight-shaped screw head forming molds, etc., must be separately molded separately to form different shapes of screw holes 3 1 and 71, and 3 7 , Not only the use of screws 3, 7 and screwdrivers is not easy to use ' This problem is relatively expensive for mold making. 3 • Convenient for applying torque: In addition, with a square punch 221 as the center, the four-wing block 222 is relatively located at four right angles to the punch 221, and the four The spiked wings are screws 4 located on the four sides of the a-pillar 221 and punched with a compound square hole and a screw hole 41 in the shape of a m-shaped hole. This is used to provide a meter-shaped screw When the driver is put on and used, the contact area between the M-shaped screwdriver and the screw * is increased, the degree of closeness between the two is further improved, and the range of the torque is spread, which helps to apply force and relatively improves the convenience of torque application. The new screw head forming mold 2 uses the four-wing block 222, the phase-protruding barb wing 223 and the two ribs 224 to arrange in a composite geometric shape of a figure-shaped, a ten-shaped, a square and a m-shaped, thereby stamping. Forming M266994, the screw 4 with the compound-shaped screw hole 41 can be universally used for flat, cross, square and metric screwdrivers. The use of the screw 4 and screwdriver is very convenient. And more helpful to mention Operating said lock screw 4 smoothness' it can indeed achieve the purpose of the present novel. However, the above are only the preferred embodiments of the new model.
