Description

Technical Field

[0001] This application relates to the field of bearing manufacturing, and more particularly to a bearing forging hole expansion support device. Background Technology

[0002] In the bearing production process, the raw materials need to be calcined at high temperature, then the raw materials are put into a forging machine to forge the inner hole. Finally, the bearing blank with the inner hole is expanded by a hole expansion device to form the outer ring of the bearing.

[0003] Specifically, hole-reaming devices such as Figure 1 As shown, the machine includes a machine body 1, on which a rolling roller 10 is rotatably mounted. The rolling roller 10 is used to place a bearing blank 102 with an inner hole. After the bearing blank 102 is rolled by the rolling roller 101 on the machine body 1, it forms the outer ring of the bearing. The rolling roller 10 is in a cantilever state. In order to prevent the rolling roller 10 from deforming, a rear support 104 is usually used to support the rolling roller 10.

[0004] The existing rolling roller 10 has defects in support. As the size and width of the processed parts increase, the rolling roller 10 is prone to breakage during the rolling process of the outer ring of the bearing, which greatly reduces the service life of the rolling roller 10 and reduces labor productivity.

[0005] Therefore, how to design a support device for a rolling mill that extends its service life has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] The self-aligning roller bearing is mounted on a support plate. The inner ring of the self-aligning roller bearing is equipped with a connecting seat. In the first state, the support plate is away from the rolling roller and the connecting seat is separated from the connecting head. In the second state, the support plate is close to the rolling roller and the connecting head is inserted into the connecting seat to support the rolling roller.

The positioning inner ring is inserted into the mounting hole, and the end wall of the self-aligning roller bearing outer ring abuts against the end wall of the positioning inner ring.

[0014] In one embodiment, a positioning ring groove is provided on the inner wall of the mounting hole, and a positioning snap ring is installed in the positioning ring groove. The side wall of the positioning snap ring abuts against the side wall of the outer ring of the self-aligning roller bearing.

[0015] In one embodiment, a connecting shaft is also included. The connecting shaft is fixedly installed on the machine body.

[0043] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] like Figure 2 As shown, the machine includes a machine body 1, on which a rolling roller 10 is rotatably connected. The rolling roller 10 supports a bearing blank 102 with an inner hole. A rolling wheel 101 is also installed on the machine body 1, which is mounted above the rolling roller 10. When the bearing blank 102 is enlarged, the position of the rolling wheel 101 is adjusted so that the outer wall of the rolling wheel 101 abuts against the bearing blank 102. As the rolling roller 10 rotates, it drives the bearing blank 102 to rotate. The rolling roller 10 squeezes the bearing blank 102, thereby enlarging the inner hole of the bearing blank 102, thus completing the enlargement process of the bearing blank 102.

[0045] Since the rolling roller 10 is in a cantilever state, as the width of the bearing blank 102 increases, the extrusion force on the rolling roller 10 increases, which can easily cause the rolling roller 10 to break. Therefore, it is necessary to strengthen the support strength of the rolling roller 10.

[0046] In this embodiment, as Figure 2 and Figure 3As shown, a support plate 2 is rotatably mounted on the machine body 1 via a connecting shaft 8. The machine body 1 also includes a drive component 5 that drives the support plate 2 to switch between a first state and a second state. A self-aligning roller bearing 3 is mounted on the support plate 2. A connecting seat 4 is mounted in the inner ring of the self-aligning roller bearing 3. The end of the rolling roller 10 away from the machine body is provided with a connecting head 103 that can be inserted into the connecting seat 4. Specifically, the projection of the axis of the connecting shaft 8 onto the rolling roller 10 is perpendicular to the axis of the rolling roller 10.

[0047] With the above settings, in the first state as follows Figure 2 As shown, at this time, the support plate 2 is in an inclined state, the self-aligning roller bearing 3 is away from the rolling mill 10, the connecting seat 4 is disengaged from the connecting head 103, and the bearing blank 102 can be installed on the rolling mill 10 through the gap between the connecting seat 4 and the connecting head 103; when the driving component 5 pushes the support plate 2 to the second state, as shown... Figure 3 As shown, the support plate 2 is in a vertical position at this time, and the connector 103 is inserted into the connector 4. At this time, the connector 4 can be used to support the end of the rolling roller 10 through the connector 103, thereby strengthening the support capacity of the rolling roller 10.

[0048] It is worth noting here that, as Figure 4 and Figure 5 As shown, the connector 103 is provided with a connecting conical surface, and the inner hole of the connector 4 is adapted to the connecting conical surface, so as to facilitate the insertion of the connector 103 into the connector 4.

[0049] During the process of the support plate 2 flipping from the first state to the second state, as the connecting head 103 contacts the connecting seat 4, the inner ring of the self-aligning roller bearing 3 and the outer ring of the self-aligning roller bearing 3 rotate relative to each other, thereby adjusting the angle of the connecting seat 4 and making it easier to insert the connecting head 103 into the inner hole of the connecting seat 4.

[0050] In order to achieve the installation of the self-aligning roller bearing 3, in this embodiment, as follows: Figure 4 and Figure 5 As shown, the support plate 2 is provided with mounting holes 21. In the second state, the axis of the mounting holes 21 coincides with the axis of the rolling roller 10, and the self-aligning roller bearing 3 is installed in the mounting holes 21.

[0051] To restrict the movement of the self-aligning roller bearing 3, a dust cover 6 is also included. The dust cover 6 is fixed to the support plate 2 by positioning screws and seals the mounting hole 21. The dust cover 6 is located on the side of the support plate 2 away from the rolling roller 10. The dust cover 6 is also provided with a positioning inner ring 61, which is inserted into the mounting hole 21. The end wall of the positioning inner ring 61 abuts against the end wall of the outer ring of the self-aligning roller bearing 3, thereby axially positioning the self-aligning roller bearing 3.

[0052] The inner wall of the mounting hole 21 is also provided with a positioning ring groove 211. A positioning snap ring 7 is installed in the positioning ring groove 211. The positioning snap ring 7 is located between the self-aligning roller bearing 3 and the rolling roller 10. The side wall of the positioning snap ring 7 abuts against the side wall of the self-aligning roller bearing 3, further restricting the self-aligning roller bearing 3 from moving axially.

[0053] It is worth noting that the dust cover 6 is designed to prevent the oxide scale that falls off during the rolling of the bearing blank 102 from entering the mounting hole 21, thus enabling the self-aligning roller bearing 3 to operate stably.

[0054] Specifically, such as Figure 6 , Figure 7 and Figure 8 As shown, a fixing plate 9 is also fixedly installed on the body 1, wherein the connecting shaft 8 is fixedly installed on the fixing plate 9, and a connecting block 22 is also fixedly installed on the support plate 2, wherein a copper sleeve 23 is installed on the connecting block 22, and the copper sleeve 23 is sleeved on the connecting shaft 8 and rotatably connected to the connecting shaft 8.

[0055] To reduce friction between the connecting shaft 8 and the copper sleeve 23, in this embodiment, such as Figure 8 and Figure 9 As shown, the end wall of the connecting shaft 8 is provided with an oil inlet 81, and also includes an oil inlet channel 82 connected to the oil inlet 81. The oil outlet of the oil inlet channel 82 is connected to the peripheral wall of the connecting shaft 8, and the oil inlet 81 is connected to external lubricating oil. At this time, the lubricating oil sprayed from the oil inlet channel 82 can enter the gap between the connecting shaft 8 and the copper sleeve 23, thereby extending the service life of the copper sleeve 23 and the connecting shaft 8.

[0056] The driving component 5 includes a driving cylinder 51, which is rotatably connected to the fixed plate 9. A connecting support 24 is fixedly provided on the support plate 2, and the cylinder rod of the driving cylinder 51 is rotatably connected to the connecting support 24.
