[0025] As Figures 1-5 shown, a bushing structure of a wire drawing machine includes a wire drawing machine 1, which is divided into a power box body part 1-1 and a water tank box body part 1-2. The power box body part 1-1 and the water tank box body part 1-2 form two working intervals through a partition plate. The power box body part 1-1 of the wire drawing machine 1 is installed with a bushing structure 2 in a detachable manner. The bushing structures 2 are arranged at intervals. The bushing structure 2 includes a bushing 2-1 and a shaft rod 2-2 rotatably connected to the bushing 2-1.
[0026] A flange connection is adopted between the power box body part 1-1 of the wire drawing machine 1 and the bushing structure 2 and is fixed by bolts.
[0027] The shaft rod 2-2 is installed in the bushing 2-1 through bearings arranged at both ends of the bushing structure 2.
[0028] An oil seal end 3 is arranged at the end part of the bushing structure 2, and a waterproof structure 4 is detachably connected to the outside of the oil seal end 3.
[0029] The above-mentioned waterproof seal is realized by the oil seal end 3 and the waterproof structure 4. When the shaft rod is in a rotating state, the waterproof structure 4 is detachably connected to the outside of the oil seal end 3 and is connected to the shaft rod 2-2 and rotates simultaneously with the shaft rod 2-2. The waterproof structure 4 prevents water from entering the oil seal, and the water flow near the oil seal end is thrown away by the rotation of the waterproof structure 4.
[0030] For the convenience of detachable installation in the use state, the bushing structure 2 installed on the power box body part 1-1 of the wire drawing machine 1 is connected to the partition plate on the wire drawing machine 1 by bolts.
[0031] For the convenience in the use state, by arranging a shaft plate 5 to prevent the proximal bearing from being corroded after water enters the oil seal, a circular shaft plate 5 is installed near the bearing at the oil seal end, and the shaft plate 5 is connected to the shaft rod 2-2.
[0032] The above-mentioned shaft plate 5 is connected to the shaft rod. When the shaft rod is in a rotating state, the shaft plate 5 rotates accordingly, and the water near the shaft plate 5 will be thrown away by the shaft plate 5.
[0033] A water hole 6 is arranged on the circumferential surface of the shaft sleeve structure 2, and the water hole 6 extends to communicate with the gap between the oil seal end 3 and the bearing.
[0034] When the shaft plate rotates, the water hitting the shaft plate will flow out through the water holes 6 after being shaken off, without affecting the bearing.
[0035] For the convenience of use, a detachable waterproof cover structure is provided on the shaft rod to prevent water in the water tank body part 1-2 from entering the interior of the bearing through the oil seal end when the wire drawing machine is working. The waterproof structure 4 is a hollow cover structure, and a gap is left between the waterproof structure 4 and the oil seal end 3.
[0036] In order to facilitate the use, the waterproof structure is limited by setting a limiting step 7 to ensure the clearance between the waterproof structure 4 and the oil seal end 3. The limiting step 7 is set on the shaft 2-2 near the oil seal end 3, and the waterproof structure 4 is sleeved on the shaft 2-2 and contacts the limiting step 7.
[0037] The outer end of the waterproof structure 4 is fixed to the shaft rod 2-2 by means of a nut.
[0038] The wire drawing machine of the utility model removes the middle bearing box and directly installs the shaft sleeve structure in the wire drawing machine, thereby solving the problem of inaccurate concentricity between bearings and preventing water from entering the shaft sleeve, thereby increasing the service life, reducing production costs by multiples, and reducing maintenance costs.
[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode is divided into only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
