Abstract: A split thread die device is disclosed. The device is comprised of a first half and a second half that can be secured to each other around a damaged area of threads of a fastener. The device can then be turned to re-thread the damaged threads. In addition, a top surface of each half is comprised of an opening that extends to the inside surface of each half. The opening allows a cutting lubricant to easily flow from the top surface of each half and onto the threads of the fastener contacting the inside surfaces.

Abstract: A repairing tool for an electric wire threading head for pressing and squeezing a drawing-in wire of the electric wire includes a first holding part, a second holding part opposite to the first holding part, and two positioning bolts for fastening the first holding part and the second holding part. A first half screw hole and a second half screw hole are protrudingly formed on the first holding part and the second holding part to form a complete screw hole. The drawing-in wire is pressed and squeezed through the positive rotation or reverse rotation of the repairing tool to form an external screw thread part and increase a screw thread area, and the surface of the external screw thread part is applied with instant dry adhesive and rotated into a pulling head, so that the drawing-in wire is closely adhered to the pulling head and tensile strength is improved.

Abstract: The disclosure relates to a die stock comprising: an annular holder having a plurality of receiving grooves; a plurality of cutting inserts; and one fixture per cutting insert for axially fixing the respective cutting insert in one of the plurality of receiving grooves. The plurality of receiving grooves are provided on an inner periphery of the annular holder and run in an axial direction parallel to a central longitudinal axis of the annular holder. Each of the plurality of receiving grooves has a receiving groove profile for receiving one of the plurality of cutting inserts. Each cutting insert is received within a respective one of the receiving grooves and comprises at least one cutting edge that is arranged on a cutting surface that faces toward the central longitudinal axis of the annular holder, wherein each cutting insert comprises a holding profile that is arranged on a holding surface opposite the cutting surface. The receiving groove profiles of the receiving grooves and the holding profiles of the cutting inserts interact with each other in such a way that a cutting insert, when inserted into its receiving groove, is guided in the axial direction parallel to the central longitudinal axis of the annular holder and, in the fully inserted state, is clamped in a radial direction perpendicular to the central longitudinal axis of the annular holder.
Abstract translation: 本公开涉及一种模具坯料，其包括：具有多个接收槽的环形保持器; 多个切削刀片; 和每个切削刀片的一个夹具，用于将相应的切削刀片轴向固定在多个接收槽中的一个中。 多个接收槽设置在环形保持器的内周上，并且沿与环形保持器的中心纵向轴线平行的轴向延伸。 多个接收槽中的每一个具有用于容纳多个切削刀片中的一个的接收槽轮廓。 每个切削刀片被容纳在相应的一个接收槽内，并且包括布置在面向环形保持器的中心纵向轴线的切割表面上的至少一个切削刃，其中每个切削刀片包括保持轮廓，该保持轮廓布置 在与切割面相对的保持面上。 接收槽的接收槽轮廓和切削刀片的保持轮廓彼此相互作用，使得当插入到其接收槽中时，切削刀片在平行于中心纵向轴线的轴向方向上被引导 并且在完全插入状态下，在垂直于环形保持器的中心纵向轴线的径向方向上被夹紧。
