Detailed Implementation

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Embodiment 1 of this utility model, as follows: Figure 1 and Figure 2 As shown, a straightening frame 2 is connected to the side of the control console 1. The mold box 3 is fixed to the control console 1 via a support flange 34. A T-shaped rod is provided on the top of the support flange. The T-shaped rod is sleeved on the mold box shaft and locked with screws to adjust the height of the mold box for easy alignment. The mold box 3 has a first mold cavity 31, a second mold cavity 32, and a third mold cavity 33 respectively. A replaceable drawing die assembly 4 is installed in the first mold cavity 31. A chip breaker assembly 5 is installed in the second mold cavity 32. A guide mold base 6 is installed on the side of the third mold cavity 33 near the straightening frame 2. A guide mold is installed at the center of the guide mold base. The drawing die assembly 4, the chip breaker assembly 5, and the guide die base 6 are coaxially mounted. A through hole with a coaxial arrangement is provided on the partition plate between two adjacent die cavities. A drive motor 7 is installed on the side of the die box 3. Different product processing functions can be achieved by different combinations of the drawing die and the peeling die located in the first die cavity. In the combination of the drawing die and the peeling die, the chip breaker is used to remove iron filings from the surface of the steel wire. In the combination of the double drawing die, the chip breaker is used to stir the drawing powder to prevent the formation of gaps during the drawing process, which would lead to poor lubrication and defects on the surface of the steel wire.

[0020] The drawing die assembly 4 includes a front flange 41 mounted on the first die cavity 31. A locking screw 42 is mounted on the center of the front flange 41 outside the first die cavity 31. A drawing die mechanism is connected to the side of the front flange 41 away from the locking screw 42. The drawing die mechanism includes a drawing die body 43 connected to the front flange 41. A spare die 45 is connected to the drawing die body 43 through a positioning sleeve 44. The steel wire enters the drawing die mechanism from the center of the locking screw and completes the corresponding processing according to the combination form in the drawing die mechanism.

[0021] The positioning sleeve 44 has a through hole in the center to connect the drawing die body 43 and the spare die 45. The positioning sleeve 44 has a waist-shaped groove on its circumference. The first die cavity 31 is filled with drawing powder or drawing oil to facilitate the drawing powder or drawing oil to pass through the positioning sleeve and contact the steel wire.

[0022] The bottom of the second mold cavity 32 is provided with a chip discharge port 321, and a cover plate can be detachably installed on the chip discharge port 321. It can be detached and installed according to different usage conditions, which is flexible and convenient.

[0023] The chip breaker assembly 5 includes a square bearing seat 51 fixed on a partition plate between the second mold cavity 32 and the third mold cavity 33. A chip breaker spindle 52 passing through the partition plate is installed in the square bearing seat 51. A driven sprocket 53 is installed on the surface of the chip breaker spindle 52 in the third mold cavity 33. A drive sprocket 71 is installed at the output end of the drive motor 7. The drive motor 7 and the chip breaker spindle 52 are driven by a chain. The chip breaker spindle 52 is connected to the chip breaker body 54 in the second mold cavity 32. The drive motor drives the chip breaker spindle to rotate.

[0024] The chip breaker body 54 includes a cutter arm 541 fixed on the chip breaker spindle 52. The cutter arm 541 has an inclined mounting groove. The chip breaker 542 is installed in the mounting groove and fixed by a pressure block 543. The tip of the chip breaker 542 faces the center of the spare die 45, which can adjust the chip breaker and the outlet of the spare die to a suitable position.

[0025] In this embodiment, the spare die 45 is a drawing die, which forms a double drawing die combination structure with the drawing die body. The chip discharge port at the bottom of the second die cavity is closed. Drawing powder is filled in the first die cavity and the second die cavity. At this time, the chip breaker rotates in the drawing powder in the second die cavity, which acts as a drawing powder agitator and better assists in the drawing and forming of the steel wire.

[0026] In another preferred embodiment of this invention, the first mold cavity is filled with drawing oil, which further improves the wire drawing effect compared to drawing powder.

[0027] The difference between Embodiment 2 and Embodiment 1 is that the spare die is a peeling die, which forms a drawing and peeling assembly with the drawing die body. The first die cavity is filled with drawing powder. After the steel wire passes through the peeling die, the chip breaker cleans the iron filings on the surface of the steel wire, and the iron filings are cleaned from the chip discharge port from time to time.
