Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing dies, in particular to a non-destructive correction device for wire drawing dies. Background Art

[0002] In metal pressure processing, the tool that forces metal to pass through the die under the action of external force, compresses the metal cross-sectional area, and obtains the required cross-sectional shape and size is called a wire drawing die. The wire drawing die makes the metal wire from thick to thin, gradually reaching the size people need, and is widely used in various industries and fields.

[0003] The existing wire drawing dies have the following main drawbacks during use: when producing and processing thin metal wires, due to the deviation between the axis of the wire drawing die and the direction of the tangent of the wire drawing wheel, the metal wire is unevenly stressed in the die, and the thin metal wire at the die outlet will bend and twist, resulting in wavy bends in the finished product. In severe cases, the finished metal wire will twist and curl, resulting in quality defects or even scrapping of the finished metal wire. Therefore, a correction device for the wire drawing die is urgently needed. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0028] The connecting plate 110 is circular, and the guide tube 120 is fixed on one side of the connecting plate 110 . At the same time, the axis of the guide tube 120 coincides with the direction of the tangent of the drawing wheel, which facilitates the subsequent correction and positioning of the drawing die body 170 .

[0029] Three through holes 111 are formed in an annular array on the connecting plate 110. The transmission member 130 includes a threaded rod 131 rotatably mounted on the inner wall of the through hole 111 and with the end thereof extending out of the connecting plate 110, and a first bevel gear 132 fixed on the end of the threaded rod 131. The first bevel gear 132 is meshed with a bevel gear ring 150. At the same time, an annular groove 113 is formed on the outer side of the connecting plate 110. The bevel gear ring 150 is rotatably engaged in the annular groove 113 to ensure the stability of the bevel gear ring 150 during rotation. In addition, the clamping block 140 is used to clamp and position the wire drawing die body 170. The clamping block 140 is T-shaped, with one end slidably engaged in the through hole 111 and the other end extending out of the through hole 111. 0 is provided with a threaded hole 141, and the threaded rod 131 passes through the threaded hole 141, and the threaded rod 131 is meshed with the threaded hole 141, so that when the bevel gear ring 150 rotates, the three first bevel gears 132 can be synchronously driven to rotate, and the rotation of the first bevel gear 132 drives the threaded rod 131 to rotate, and the threaded rod 131 rotates in the threaded hole 141 of the clamping block 140, driving the clamping block 140 to move, and the three clamping blocks 140 move synchronously toward the center to clamp and center the wire drawing die main body 170, ensuring that the axis of the wire drawing die main body 170 and the axis of the guide tube 120 are located on the same line, and can be applicable to the wire drawing die main body 170 of different diameters, further increasing the practical performance.
