Description

Technical Field

[0001] The present application relates to the technical field of disassembly tools, and in particular to a disassembly tool for a sealing structure of a support roller of a cold rolling mill. Background Art

[0002] The rolling mill is a device that realizes the metal rolling process. The rolling mill is equipped with support rolls to support the working rolls or intermediate rolls to prevent the working rolls from bending and deforming, which may affect the output and quality of the plates and strips. Figure 3-5 As shown, the end of the support roller 18 is installed in the bearing seat 13 through the bearing 14. The bearing seat 13 is fixed on the rolling mill body. A sealing structure 15 is arranged between the end of the support roller 18 and the bearing seat 13. The sealing structure 15 is a large-sized external metal skeleton seal. The sealing structure 15 consists of an inner seal 16 and an outer seal 17 to prevent the external emulsion medium from entering the thin oil lubrication system of the support roller bearing.

[0003] In order to prevent the oil in the thin oil lubrication system of the support roller bearing from deteriorating, the support roller seal needs to be replaced regularly. Since the outer seal is in contact with a large amount of emulsion, while the inner seal is in contact with less emulsion and has better working conditions than the outer seal, the service life of the outer seal is much shorter than that of the inner seal. Therefore, when the inner seal is intact, only the outer seal needs to be replaced to reduce losses.

[0004] At present, the knocking disassembly method is usually used for disassembly of the support roller seal. The disadvantages of knocking disassembly are high labor intensity, low disassembly efficiency, potential safety hazards of injury, and easy deformation and damage of the outer seal and the inner seal, resulting in economic losses. Summary of the invention

[0005] The purpose of the embodiment of the present application is to provide a disassembly tool for the sealing structure of the support roller of a cold rolling mill, so as to reduce the labor intensity of operators, improve the disassembly efficiency of the support roller sealing structure, and achieve protective disassembly of the sealing structure accurately and without damage.

[0006] The present application embodiment provides a disassembly tool for a cold rolling mill support roller sealing structure, which adopts the following technical solution:

[0007] A disassembly tool for a cold rolling mill support roller sealing structure comprises a lever, a support structure and a connecting structure, wherein the support structure is arranged on the lever, the connecting structure comprises an adjusting member and a connecting member, the adjusting member passes through the lever, and the connecting member is installed on the adjusting member.

[0008] Preferably, the connecting member is configured as a claw hook.

[0009] Preferably, the adjusting member is configured as an adjusting screw.

[0010] Preferably, a first knob is provided at one end of the adjusting member away from the connecting member.

[0011] Preferably, a threaded sleeve is provided inside the lever, and the adjusting member passes through the threaded sleeve.

[0012] Preferably, the supporting structure comprises a sliding member, a locking member and a supporting member, the sliding member is slidably mounted on the lever, and the locking member and the supporting member are respectively arranged at two ends of the sliding member.

[0013] Preferably, the locking member is configured as a locking bolt.

[0014] Preferably, a second knob is provided at one end of the locking member away from the sliding member.

[0015] Preferably, one end of the support member away from the sliding member has a smooth arc surface.

[0016] Preferably, a handle is provided at the end of the lever.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] The present application sets a lever, a supporting structure and a connecting structure. When the sealing structure of the support roller of the cold rolling mill is disassembled, based on the lever principle, the outer seal is clamped by the connecting structure and the supporting structure is pressed against the bearing seat. Then, the outer seal can be pried out easily and conveniently under the action of the lever, thereby reducing the labor intensity of the operator and improving the disassembly efficiency of the sealing structure. After the outer seal is pried out, both the inner seal and the outer seal are intact, thereby realizing protective disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
