[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the first embodiment of a roller changing fixture for a hot rolling production line of bar and wire materials provided by this utility model; Figure 2 for Figure 1 The diagram shows the working state structure. Figure 3 for Figure 1 The diagram shows a top view of the upper base plate structure. Figure 4 for Figure 1 The diagram shows a top view of the lower base plate. A roller changing fixture for a clamping machine in a hot rolling production line for bar and wire materials includes: a lower base plate 1;

[0029] Upper base plate 3, which is disposed on top of lower base plate 1;

[0030] Two connectors 2 are respectively disposed at both ends between the lower base plate 1 and the upper base plate 3, for connecting the lower base plate 1 and the upper base plate 3;

[0031] The limiting bolt 6 is threadedly connected to the inside of the upper base plate 3. The bottom of the limiting bolt 6 is provided with a jack housing 8, and the inside of the jack housing 8 is provided with a jack inner column 7.

[0032] The bottom of the connector 2 is threaded to the inside of the lower base plate 1, and the top of the connector 2 penetrates the bottom of the upper base plate 3 and extends to the top.

[0033] A gasket 4 is fitted on the outer side of the connector 2, and a nut 5 is threaded onto the outer side of the connector 2.

[0034] The gasket 4 is disposed on the top of the upper base plate 3, and the nut 5 is disposed on the top of the gasket 4.

[0035] The bottom plate 1 serves as the basic support component of the entire tooling. In practical applications, its size and shape are specially designed according to the end size and shape of the tensioning sleeve of the clamping machine. It is usually made of high-strength, lightweight alloy material, which can ensure sufficient strength to bear the pressure during the entire roller changing process, while reducing the overall weight of the tooling and making it convenient for operators to handle and install. Its internal hole design is precisely matched with the outer platform of the tensioning sleeve to ensure a tight fit during installation and achieve a stable connection.

[0036] The upper base plate 3 is also made of high-strength alloy;

[0037] The connector 2 is a double-threaded rod. When in use, the bottom of the connector 2 is threaded into the inside of the lower base plate 1, and the top of the connector 2 penetrates the bottom of the upper base plate 3 and extends to the top, where it is threadedly connected to the nut 5.

[0038] The bottom of the limit bolt 6 is equipped with a jack housing 8, which provides a stable installation position and protection for the jack. When selecting a jack, considering the actual needs of the pinch conveyor for changing rollers, a disc jack with a working pressure of 10MPa, a stroke greater than 30mm, and a small outer diameter is selected. This type of jack has the characteristics of small size, high pressure, and suitable stroke, which can meet the thrust requirements when disassembling the pinch roller. At the same time, it is also equipped with a pressure-pressurizing and pressure-releasing mechanism to facilitate the operator to control the working status of the jack. The jack inner column 7 set inside the jack housing 8 is the key component for realizing the disassembly of the pinch roller.

[0039] The working principle of the roll changing fixture for the pinch machine in a hot rolling production line for bar and wire provided by this utility model is as follows:

[0040] Please see Figure 2 When disassembling the tensioning sleeve, firstly, according to the size of the tensioning sleeve, fit the lower base plate 1 onto the end of the tensioning sleeve and rotate it so that its inner hole overlaps and is fixed with the outer platform of the tensioning sleeve. Next, place the hydraulic jack (select a disc jack with a working pressure of 10MPa, a stroke greater than 30mm, and a small outer diameter, and equipped with a pressure-pressurizing and pressure-releasing mechanism) between the shaft head and the limit bolt 6, level and fix it. Then, by continuously pressing, the inner column 7 of the jack pushes the shaft head, which in turn pushes the roller changing fixture to move outward from the shaft head, driving the tensioning sleeve and the clamping roller to move outward, thereby realizing the disassembly of the clamping roller. During the installation and use of the fixture, the connecting piece 2 is threaded to the lower base plate 1 at the bottom and passes through the upper base plate 3 at the top, and is equipped with a washer 4 and a nut 5 to ensure the stability of the connection between the upper and lower base plates. The limit bolt 6 provides stable support and positioning for the jack.

[0041] Compared with related technologies, the roller changing fixture for a pinch feeder in a hot rolling production line for bar and wire provided by this utility model has the following advantages:

[0042] The lower base plate 1, connecting piece 2, upper base plate 3, limiting bolt 6, jack inner column 7, and jack outer shell 8 work together to form a more reasonable and easier-to-install and operate tool compared to traditional roller changing tools. At the same time, the overall tool is lighter, which effectively improves the changing efficiency of the pinch rollers, reduces the labor intensity of operators, and solves the problems of heavy weight, complicated operation, low efficiency, and poor safety and reliability of traditional pinch machine roller changing tools.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides a roller changing fixture for a pinch conveyor in a hot rolling production line for bar and wire, the second embodiment of this application proposes another roller changing fixture for a pinch conveyor in a hot rolling production line for bar and wire. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the difference in the second embodiment of this application regarding the roller changing fixture for a clamping machine in a hot rolling production line for bar and wire materials is that the roller changing fixture for a clamping machine in a hot rolling production line for bar and wire materials further includes an adjusting screw 91. The adjusting screw 91 is threaded to the bottom of the connecting member 2, and the adjusting screw 91 also passes through the interior of the lower base plate 1. A sliding cavity 91 is provided inside the adjusting screw 91, and an elastic member 92 is provided on the inner side of the sliding cavity 91. Limiting plates 93 are fixedly installed at both ends of the elastic member 92, and a snap-fit ​​member 94 is fixedly installed on one side of the limiting plate 93.

[0046] The snap-fit ​​component 94 is slidably connected to the inside of the side of the adjusting screw 91.

[0047] The top of the snap-fit ​​member 94 is located at the bottom of the lower base plate 1.

[0048] When installing with a base plate 1 of different thicknesses, if the top of the snap-fit ​​94 is a certain distance from the bottom of the base plate 1, the user can rotate the adjusting screw 9 so that the top of the adjusting screw 9 is threaded into the bottom of the connector 2, thereby making the top of the snap-fit ​​94 contact the bottom of the connector 2.

[0049] The working principle of the roll changing fixture for the pinch machine in a hot rolling production line for bar and wire provided by this utility model is as follows:

[0050] When it is necessary to disassemble the tensioning sleeve of different sizes, the user can replace the different lower base plate 1 to cooperate with the tensioning sleeve. When replacing the lower base plate 1, the user can push the two snap-fit ​​pieces 94 towards the middle, thereby driving the two limiting plates 93 to move towards the middle, thereby squeezing the elastic member 92 and storing the snap-fit ​​pieces 94 into the inner side of the slide cavity 91. Then, the connecting piece 2 can be moved upward to disassemble the connecting piece 2 and the lower base plate 1.

[0051] When it is necessary to install the connector 2 and the lower base plate 1, simply align the bottom of the adjusting screw 9 with the hole on the lower base plate 1 and pass the adjusting screw 9 through the hole. At this time, the snap-fit ​​94 will pop out and snap into the bottom of the lower base plate 1, thereby achieving the function of installing the connector 2 and the lower base plate 1.

[0052] Compared with related technologies, the roller changing fixture for a pinch feeder in a hot rolling production line for bar and wire provided by this utility model has the following advantages:

[0053] By adjusting the screw 9, the sliding cavity 91, the elastic element 92, the limiting plate 93, and the snap-fit ​​element 94, the connection between the connector 2 and the lower base plate 1 can be disassembled and installed by simply pressing the snap-fit ​​element 94 and popping it out. This makes the operation convenient and quick, increasing the installation efficiency.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
