Description

Technical Field

[0001] The utility model belongs to the technical field of wire drawing die processing, and in particular relates to a wire drawing die inner hole grinding device. Background Art

[0002] The wire drawing die is a die through which the metal wire passes, so that it gradually changes from thick to thin and reaches the size people need. This special die is the wire drawing die. The common wire drawing die uses natural diamond as raw material, so it has strong wear resistance and long service life.

[0003] When processing the wire drawing die, it is necessary to first grind a tapered groove in the center of the die, and then use laser to punch out drawing holes of different specifications at the bottom of the tapered groove according to customer requirements. Since the inner wall of the drawing hole punched by the laser is relatively rough, the wire drawing die cannot be put into use directly, so it is also necessary to polish the drawing hole and the inner wall of the wire drawing die. When polishing the inner hole of the wire drawing die, the existing polishing device places the wire drawing die in the polishing device and drives the wire drawing die to rotate, and at the same time places the grinding rod in the inner hole of the wire drawing die for grinding. During grinding, since the contact between the grinding rod and the wire drawing die hole is linear contact, the grinding rod is severely worn at the contact line where it is in contact with the inner wall of the wire drawing die hole for grinding, while other parts that are not in contact with the inner wall of the wire drawing die hole are still as good as new. This not only reduces the service life of the grinding rod, but also wastes the material for preparing the grinding rod. Utility Model Content

[0080] It also includes a sliding mechanism 3, which includes a pair of sliding rods 31 arranged on the support frame 1, a slider seat 33 slidingly sleeved on the pair of sliding rods 31, a sliding assembly 34 arranged on the slider seat 33, and a fixing mechanism 39 arranged on the slider seat 33 and tightly against the sliding rods 31, and the grinding rod clamping mechanism is rotatably installed on the sliding assembly 34.

[0081] It also includes a reset mechanism 5, which includes a first connecting column 51 arranged on the grinding rod clamping mechanism, a second connecting column 52 arranged on the slider seat 33, and a reset spring 53 arranged between the first connecting column 51 and the second connecting column 52.

[0082] Based on Example 5, this Example 9 provides a more preferred structure of the reset mechanism 5, specifically: it also includes a reset mechanism 5, the reset mechanism 5 includes a first connecting column 51 arranged on the grinding rod clamping mechanism, a second connecting column 52 arranged on the slider seat 33, and a reset spring 53 arranged between the first connecting column 51 and the second connecting column 52.

[0083] The reset mechanism 5 of the utility model can make the grinding rod 7 always in contact with the hole wall of the inner hole of the wire drawing die during grinding. Specifically, the first connecting column 51 is arranged on the mounting plate 41, and the second connecting column 52 is arranged on the slider seat 33. The first connecting column 51 and the second connecting column 52 are connected by the reset spring 53. When the grinding rod 7 is grinding the inner hole of the wire drawing die, when the mounting plate 41 rotates along the axis of the assembly shaft 412, the second connecting column 52 rotates with the mounting plate 41 so that the reset spring 53 is deformed. At the same time, when the grinding rod 7 is placed in the inner hole of the wire drawing die, the grinding rod 7 is under the action of the force generated by the deformation of the reset spring 53, so that the grinding rod 7 is always in contact with the hole wall of the inner hole of the wire drawing die, which can facilitate the grinding of the hole wall of the inner hole of the wire drawing die.

The grinding rod 7 is located in the wire drawing die and the two rotate in opposite directions.

[0086] It also includes a sliding mechanism 3, which includes a pair of sliding rods 31 arranged on the support frame 1, a slider seat 33 slidingly sleeved on the pair of sliding rods 31, a sliding assembly 34 arranged on the slider seat 33, and a fixing mechanism 39 arranged on the slider seat 33 and tightly against the sliding rods 31, and the grinding rod clamping mechanism is rotatably installed on the sliding assembly 34.

[0087] The wire drawing die clamping mechanism comprises a first motor 6 arranged on a support frame 1, and a three-jaw chuck 2 arranged on a driving shaft of the first motor 6, and the wire drawing die is clamped in the three-jaw chuck 2;

[0088] The fixing mechanism 39 includes a threaded hole 391 formed on the slider seat 33 , and a fastening bolt 392 threadedly connected in the threaded hole 391 and tightly abutting against the corresponding sliding rod 31 .

[0089] This embodiment 10 provides a more preferred structure of the wire drawing die clamping mechanism based on the embodiment 5, specifically: the wire drawing die clamping mechanism includes a first motor 6 arranged on the support frame 1, and a three-jaw chuck 2 arranged on the driving shaft of the first motor 6, and the wire drawing die is clamped in the three-jaw chuck 2;

[0090] The fixing mechanism 39 includes a threaded hole 391 formed on the slider seat 33 , and a fastening bolt 392 threadedly connected in the threaded hole 391 and tightly abutting against the corresponding sliding rod 31 .

[0091] The first motor 6 of the utility model is installed on the support frame 1, and a three-jaw chuck 2 is arranged on the driving shaft of the first motor 6. The wire drawing die is clamped by the three-jaw chuck 2 and the three-jaw chuck 2 is rotated under the drive of the first motor 6. The three-jaw chuck 2 drives the wire drawing die to rotate, so that the wire drawing die can be polished easily.

[0092] The fixing mechanism 39 of the utility model includes a threaded hole 391 opened on the slider seat 33, and a fastening bolt 392 threadedly connected to the threaded hole 391 and tightly abutted against the corresponding sliding rod 31. Specifically, the fastening bolt 392 can facilitate the fixing of the slider seat 33, thereby facilitating the adjustment of the position of the slider seat 33.

[0093] The working principle of this utility model:

[0094] When in use, first clamp the wire drawing die in the three-jaw chuck 2, adjust the distance between the slider seat 33 and the three-jaw chuck 2, and rotate the mounting plate 41 at the same time, so that the grinding rod 7 can pass through the inner hole of the wire drawing die. At the same time, the mounting plate 41 causes the reset spring 53 to deform when rotating, so that the grinding rod 7 contacts the wall of the inner hole of the wire drawing die. By adjusting the distance of the sliding block 387 in the turntable 382, ​​the grinding rod 7 will not fall off from the inner hole of the wire drawing die during the reciprocating movement. Rotate the fixing mechanism 39 to fix the slider seat 33 on the sliding rod 31, and start the second The motor 381, the second motor 381, the third motor 45, and the first motor 6 drive the three-jaw chuck 2 to rotate, and the third motor 45 drives the driving pulley 46. The driving pulley 46 drives the driven pulley 47 to rotate through the belt 48, thereby driving the drill clamp 43 and the grinding rod 7 to rotate, and the rotation direction of the second motor 381 is opposite to the rotation direction of the first motor 6. At the same time, the second motor 381 drives the transmission rod 385 to move through the rotating shaft 384, thereby pushing the sliding plate 37 to reciprocate along the slide rail 35, thereby realizing the grinding of the inner hole of the wire drawing die.

[0095] The first motor 6, the second motor 381, the third motor 45, the three-jaw chuck 2, and the drill clamp 43 used in the utility model are all existing equipment and can be directly purchased and used on the market. Therefore, the circuit, structure and control principle of the first motor 6, the second motor 381, the third motor 45, the three-jaw chuck 2, and the drill clamp 43 are not described here in detail.
