Description

Technical Field

[0001] This application relates to the technical field of strip pickling, and particularly to a backstop flange adapter for a round nut. Background Art

[0002] Currently, after strip steel is pickled in the cold line pickling area, the strip steel is passed through between two squeeze rolls. The two squeeze rolls cooperate to dry the strip steel and convey it. The squeeze roll is connected to a coupling through a flange adapter. The flange adapter is sleeved on the squeeze roll and is key-connected to the flange adapter.

[0003] The axial limit of the squeeze roll is very important. The squeeze roll uses a bearing, a positioning sleeve, and a backstop washer to cooperate to limit its own axial direction. Figure 1 The bearing is sleeved on the squeeze roll, the positioning sleeve is sleeved on the squeeze roll and abuts against the bearing for limiting the bearing. The backstop washer is a washer that uses the cooperation of a stop ear, an opening of a round nut, and a keyway of a shaft to prevent the round nut from loosening. The backstop washer is sleeved on the squeeze roll and abuts against the positioning sleeve to achieve the limit of the positioning sleeve.

[0004] However, it is found in the use process that due to frequent disassembly and assembly of the round nut, the locking effect is not good due to wear and other reasons, and the round nut is extremely likely to fall off, causing displacement of the positioning sleeve and the bearing, and axial movement of the squeeze roll, resulting in a fault stop, affecting production efficiency and product quality. Utility Model Content

[0005] In order to reduce the possibility of affecting production efficiency and product quality due to axial displacement of the squeeze roll, the present utility model provides a backstop flange adapter for a round nut.

[0006] The backstop flange adapter for a round nut provided by the present utility model adopts the following technical solutions:

[0007] A backstop flange adapter for a round nut includes a main body, a first end plate, and a second end plate. The main body is sleeved on the squeeze roll and is key-connected to the squeeze roll. The first end plate and the second end plate are sleeved on the main body. The first end plate is connected to the coupling, and a contact portion for abutting against the round nut is provided on the side wall of the second end plate.

[0008] By adopting the above technical solutions, during use, the main body is sleeved on the squeeze roll, and the contact portion of the second end plate abuts against the round nut to limit the round nut, reducing the possibility of the round nut having a reduced locking effect or falling off due to frequent disassembly and assembly, thereby reducing the possibility of the squeeze roll moving axially, improving the stability and production efficiency of the equipment, and ensuring product quality at the same time.

[0009] Preferably, a clamping groove is formed at one end of the main body close to the coupling. A fixing plate is arranged in the clamping groove. The fixing plate is threadedly connected with a screw, and the screw is threadedly connected with the squeezing roller, so as to fix the main body and the squeezing roller.

[0010] By adopting the above technical solution, the anti-backlash flange adapter and the squeezing roller are fixed by using the screw and the fixing plate, reducing the possibility of displacement between the anti-backlash flange adapter itself and the squeezing roller.

[0011] Preferably, the abutting portion includes a protruding portion arranged on the side wall of the second end plate. The protruding portion is close to the edge of the second end plate, and the protruding portion abuts against the round nut.

[0012] By adopting the above technical solution, when the round nut is installed, there may be a deviation in the installation position of the round nut, so that the side wall of the second end plate may directly abut against the shaft shoulder. Therefore, the protruding portion facilitates the abutment between the second end plate and the round nut.

[0013] Preferably, the thickness of the protruding portion is 2 mm.

[0014] By adopting the above technical solution, the protruding portion with a thickness of 2 mm ensures the abutting strength. If the thickness of the protruding portion is too large, it may affect the assembly of other components.

[0015] Preferably, a groove is formed on the side wall of the second end plate. The groove is located on one side of the protruding portion close to the main body.

[0016] By adopting the above technical solution, the design of the groove is to reduce the damage caused by stress when the side wall of the second end plate abuts against the shaft shoulder.

[0017] Preferably, the longitudinal section of the second end plate is in a circular ring shape.

[0018] By adopting the above technical solution, the circular ring-shaped second end plate can reduce the possibility of harm to the operator during the disassembly process.

[0019] Preferably, the outer diameter of the second end plate is 140 mm, and the thickness of the second end plate is 15 mm.

[0020] By adopting the above technical solution, it will not excessively increase the volume and weight of the entire anti-backlash flange adapter, and can ensure its effective abutting area with the round nut, reducing material waste and assembly difficulties.

[0021] Preferably, the first end plate and the second end plate are respectively located on both sides of the main body, and the main body, the first end plate and the second end plate are integrally formed.

[0022] By adopting the above technical solution, it is convenient for the processing of the first end plate, the second end plate and the main body, and enhances the overall structural strength and service life.

[0023] Preferably, the main body, the first end plate and the second end plate are all made of low alloy structural steel.

[0024] By adopting the above technical solution, low alloy structural steel has high strength, good plasticity, good weldability and corrosion resistance, meeting various usage requirements of the anti-backlash flange adapter.

[0025] In summary, the present utility model has the following beneficial effects:

[0026] During use, the main body is sleeved on the squeezing roller, and the abutting portion of the second end plate abuts against the round nut to limit the round nut, reducing the possibility of the round nut having a reduced locking effect or falling off due to frequent disassembly and assembly, thereby reducing the possibility of the squeezing roller moving axially, improving the stability and production efficiency of the equipment, and ensuring product quality at the same time.

[0032] The following further describes the present utility model in detail with reference to the drawings.

[0033] An anti-backlash flange adapter for a round nut, referring to Figure 2 and Figure 3 , includes a main body 2, a first end plate 3 and a second end plate 4. The main body 2 is sleeved on the squeezing roller and is key-connected to the squeezing roller. The first end plate 3 and the second end plate 4 are sleeved on the main body 2. The first end plate 3 is connected to the coupling, and the side wall of the second end plate 4 is provided with an abutting portion that abuts against the round nut.

[0034] During use, the main body 2 is sleeved on the squeezing roller, and the abutting portion of the second end plate 4 abuts against the round nut to limit the round nut, reducing the possibility that the locking effect of the round nut is reduced or the nut falls off due to frequent disassembly and assembly, thereby reducing the possibility of the squeezing roller moving axially, improving the stability and production efficiency of the equipment, and ensuring the product quality at the same time.

[0035] Refer to Figure 3 , the main body 2 is a cylindrical barrel, and the main body 2 matches the shaft of the squeezing roller. Both the first end plate 3 and the second end plate 4 are plate-shaped bodies with an annular longitudinal section. The first end plate 3 and the second end plate 4 are respectively located on both sides of the main body 2, and the main body 2, the first end plate 3 and the second end plate 4 are integrally formed, which is convenient for the processing of the first end plate 3, the second end plate 4 and the main body 2, and enhances the overall structural strength and service life.

[0036] Refer to Figure 3 , the main body 2, the first end plate 3 and the second end plate 4 are all made of low-alloy structural steel. Low-alloy structural steel has high strength, good plasticity, good weldability and corrosion resistance, meeting the various usage requirements of the anti-retreat flange coupling.

[0037] Refer to Figure 2 , a clamping groove 21 is formed on the side wall of the main body 2 away from the round nut, and the length of the clamping groove 21 is greater than the inner diameter of the main body 2. A fixing plate 22 is arranged in the clamping groove 21, and the fixing plate 22 matches the clamping groove 21. The fixing plate 22 is threadedly connected with a screw, and the screw passes through the fixing plate 22 and is threadedly connected with the extrusion roller, realizing the fixation of the fixing plate 22 and the extrusion roller.

[0038] Refer to Figure 3 , a plurality of through holes 31 are formed on the side wall of the first end plate 3 away from the second end plate 4, and the plurality of through holes 31 are equidistantly distributed along the circumferential direction of the first end plate 3. It is fixed to the coupling through the plurality of through holes 31.

[0039] Refer to Figure 3 , the outer diameter of the second end plate 4 is 140 mm and the thickness is 15 mm.

[0040] Refer to Figure 3 , the abutting portion includes a convex portion 41, the thickness of the convex portion 41 is 2 mm, and the width is 7.13 mm. The convex portion is annular, and the outer diameter of the convex portion is the same as the outer diameter of the second end plate 4.

[0041] When installing the round nut, there is a deviation in the installation position of the round nut, so that the side wall of the second end plate 4 directly abuts against the shaft shoulder or there is a distance between the side wall and the shaft shoulder. Therefore, the convex portion facilitates the abutment of the second end plate 4 against the round nut. Even if the side wall of the second end plate 4 directly abuts against the shaft shoulder and there is a distance between the convex portion 41 and the round nut, the moving space of the round nut is very small, reducing the possibility of axial movement of the squeezing roller, and further reducing the possibility of affecting the production efficiency and product quality due to the axial displacement of the squeezing roller.

[0042] Referring to Figure 3 , a groove 42 is formed in the side wall of the second end plate 4 close to the nut, and the groove 42 is annular. The depth of the groove 42 is 3 mm and the width is 7.87 mm.

[0043] The working principle of this application is as follows: During use, the main body 2, the first end plate 3 and the second end plate 4 are sleeved on the squeezing roller, the main body 2 is key-connected to the squeezing roller, the fixing plate 22 is placed in the card slot 21, and screws are used to pass through the fixing plate 22 and the squeezing roller to fix the fixing plate 22 and the squeezing roller, thereby fixing the position of the anti-rotation flange coupling. The convex portion 41 of the second end plate 4 limits the round nut, reducing the possibility of axial movement of the squeezing roller, and further reducing the possibility of affecting the production efficiency and product quality due to the axial displacement of the squeezing roller.

[0044] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
