Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
As shown in fig. 2 to 5, the repairing method for the guide wheel provided by the present invention includes the following steps: the guide wheel 1 is ground in an area to be repaired, and a wear-resistant material is additionally arranged on the ground area to be repaired, wherein the wear-resistant material is a wear-resistant welding material or a wear-resistant plate. The repairing method for the guide wheel 1 provided by the invention can repair the worn area of the guide wheel 1, so that the repaired guide wheel 1 can be normally used, the frequency of replacing a new guide wheel by a user is reduced, and the cost is reduced.
Wherein, wear-resisting material is wear-resisting welding material, that is to say after polishing the wearing and tearing region of leading wheel 1, and usable wear-resisting welding rod or wear-resisting welding wire carry out build-up welding to the region of polishing and handle, make the thickness increase of the regional that leads wheel 1 corresponds, make its ability normal use. The wear-resistant material is a wear-resistant plate, which means that after a wear area of the guide wheel 1 is polished, a plate, such as the wear-resistant plate 2, can be welded on the polished area, so that the thickness of the area corresponding to the guide wheel 1 is increased, and the guide wheel can be normally used. The repair method is described in detail below.
As shown in fig. 2, in order to obtain the guide wheel 1 with the wheel shoulder 11 in a worn state (fig. 1a and 1b are schematic views when the wheel shoulder 11 is not worn), the method for repairing the guide wheel in the present embodiment specifically includes the following steps:
s1: grinding a wheel shoulder 11 to be repaired of the guide wheel 1 along the circumferential direction of the guide wheel 1;
s2: the annular wear-resistant ring 3 is sleeved on the ground wheel shoulder 11 to connect the annular wear-resistant ring 3 and the guide wheel 1.
In the above step S1, for convenience of operation, as shown in fig. 2, the circumferential side surface in a worn state on the shoulder 11 to be repaired may be machined into a cylindrical surface along the circumferential direction of the guide wheel 1 using a lathe; in the above step S2, the annular wear ring 3 and the guide wheel 1 are preferably welded.
Obviously, in order to avoid significant relative movement between the annular wear-resistant ring 3 and the wheel shoulder 11 during use or to increase the friction between the annular wear-resistant ring 3 and the wheel shoulder 11, it is preferable in this embodiment that the annular wear-resistant ring 3 and the wheel shoulder 11 to be ground are in interference fit. It should be noted that, in the manufacturing process of the annular wear-resistant ring 3, when the tolerance of the interference fit between the annular wear-resistant ring 3 and the polished wheel shoulder 11 is too large (that is, the diameter of the inner wall 33 of the annular wear-resistant ring 3 is too small), the inner wall 33 of the annular wear-resistant ring 3 can be machined by using a lathe, so that the diameter of the inner wall 33 of the annular wear-resistant ring 3 is increased, the tolerance of the interference fit between the annular wear-resistant ring 3 and the polished wheel shoulder 11 is further reduced, and the annular wear-resistant ring 3 can be sleeved on the polished wheel shoulder 11.
The annular wear-resistant ring 3 and the guide wheel 1 can be extruded by a press machine, so that the annular wear-resistant ring 3 is sleeved on the wheel shoulder 11 of the guide wheel 1 after being polished. When a press machine is not used, the annular wear-resistant ring 3 can be heated firstly, so that the heated diameter of the annular wear-resistant ring 3 is increased, and then the annular wear-resistant ring 3 is sleeved on the wheel shoulder 11 of the guide wheel 1.
As shown in fig. 4, in order to facilitate welding of the annular wear-resistant ring 3 to the guide wheel 1, it is preferable that one end of the annular wear-resistant ring 3 is provided with a first welding bevel 31, and the other end of the annular wear-resistant ring 3 is provided with a second welding bevel 32.
As shown in fig. 2 to 5, in the present embodiment, a preferable method for processing the annular wear-resistant ring 3 is further provided, which specifically includes the following steps:
a1: selecting a wear-resisting plate 2 with a corresponding thickness according to the diameter of a standard wheel shoulder, and processing two end faces of the wear-resisting plate 2 in the length direction into two inclined planes 21 which are parallel to each other;
a2: winding the wear plate 2 along the length direction of the wear plate 2 to form a circular ring, and welding the two inclined planes 21 together to form the annular wear ring 3;
a3: a first welding bevel 31 is processed at one end of the annular wear-resistant ring 3, and a second welding bevel 32 is processed at the other end of the annular wear-resistant ring 3.
In the step a1, the standard shoulder diameter is: the diameter of the shoulder 11 of the guide wheel 1 is shown in fig. 1 when the shoulder 11 is not worn.
The manufacturing process of the annular wear-resistant ring 3 is as follows: assuming a standard shoulder diameter of 400mm, the thickness of the wear plate 2 includes a variety of thickness specifications, 10mm, 11mm, 12mm, etc. During use of the guide wheel 1, the shoulder 11 wears down so that the diameter of the shoulder 11 decreases. At this time, the wear surface of the shoulder 11 (the circumferential side surface of the shoulder 11) is machined into a cylindrical surface by a lathe, and the diameter of the machined shoulder 11 is assumed to be 380 mm. A wear plate 2 with a thickness of 10mm should be selected according to the standard wheel shoulder diameter (400mm), and the wear plate 2 is made into an annular wear ring 3 to be sleeved on the machined wheel shoulder 11, so that the diameter of the wheel shoulder 11 of the repaired guide wheel 1 is close to the standard wheel shoulder diameter.
Preferably, the first welding groove 31 in the present embodiment has a tapered structure, and the first welding groove 31 extends from an end face of one end of the annular wear-resistant ring 3 to the inner wall 33 of the annular wear-resistant ring 3. The second welding bevel 32 is of a conical structure, and the second welding bevel 32 extends from the circumferential side of the annular wear-resistant ring 3 to an inner wall 33 at the other end of the annular wear-resistant ring 3. The first welding groove 31 and the second welding groove 32 have the same orientation.
When in use, the second welding bevel 32 is close to the boss 12 of the guide wheel 1, and the annular wear-resistant ring 3 is connected with the guide wheel 1 in a welding way through the two welding bevels.
Obviously, in order to restore the guide wheel 1 to a normal use state, the worn region of the wheel shoulder 11 of the guide wheel 1 may be ground, and then the ground region of the wheel shoulder 11 of the guide wheel 1 may be subjected to a surfacing treatment using a wear-resistant welding rod or a wear-resistant welding wire, so that the diameter of the region corresponding to the wheel shoulder 11 is increased.
The invention also provides a guide wheel which is repaired by the guide wheel repairing method recorded in the scheme.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
