Description

Technical Field

[0001] The application discloses a shaping ring, and in particular relates to a shaping ring for semi-finished blanks. Background Art

[0002] For a type of semi-finished blank, it is usually necessary to cool and shape it after its initial forming so that the shape and size of the finished product meet the quality requirements, such as annular products such as sealing gasket blanks for electrolytic cells. In the prior art, the semi-finished blank to be cooled and shaped is generally sleeved on a shaping round tube for shaping. After cooling and shaping, the semi-finished blank is pressed out of the shaping round tube using a molding machine. However, for semi-finished blanks with larger sizes, since the semi-finished blank has a greater clamping force on the shaping round tube, the semi-finished blank is often damaged during the process of pressing the semi-finished blank out of the shaping round tube, and the shaping round tube is deformed. Utility Model Content

[0003] The purpose of the present application is to provide a shaping ring to prevent damage to a semi-finished blank during the shaping process, while improving the processing efficiency of shaping the semi-finished blank.

[0004] In order to achieve the above objectives, this application provides the following technical solutions:

[0005] A shaping ring is suitable for shaping a semi-finished blank, and the shaping ring comprises:

[0006] The ring body comprises at least two ring parts connected in sequence along its circumference, and two adjacent ring parts are detachably fixedly connected, wherein the circumferential length of at least one ring part is less than half of the circumferential length of the ring body.

[0007] When the shaping ring provided by the utility model is used, first, the at least two ring parts are fixedly connected end to end in sequence to form a ring body, and the semi-finished blank after the initial shaping is sleeved on the outside of the ring body, or in other words, the semi-finished blank after the initial shaping is sleeved on the side of the ring body away from the center of the circle. After the semi-finished blank sleeved on the ring body is cooled and shaped, one or more ring parts are driven to move radially toward the center of the shaping ring by manual or mechanical means, so that one or more ring parts are separated from the semi-finished blank sleeved on the ring body, thereby reducing the clamping force of the semi-finished blank on the shaping ring, and facilitating the removal of the semi-finished blank from the position where the ring parts are separated from the semi-finished blank. In addition, before cooling and shaping the next semi-finished blank, one or more ring parts are driven to move radially toward the direction away from the center of the shaping ring by manual or mechanical means, and then multiple ring parts are fixedly connected end to end in sequence to form a ring body.

[0008] As can be seen from the above, in the process of cooling and shaping the semi-finished blank using the shaping ring provided by the utility model, after the cooling and shaping is completed, one or more ring parts are driven to move toward the center of the circle by manual or mechanical means, thereby reducing the clamping force of the semi-finished blank on the shaping ring, and then the semi-finished blank can be directly taken out from the position where the ring parts are separated from the semi-finished blank, which is convenient for operation and improves processing efficiency. Compared with the prior art, which uses a molding machine to press the semi-finished blank from the shaping round tube, it can prevent damage to the semi-finished blank and reduce equipment costs.

[0009] In one implementation, the number of ring segments is three or more, so as to minimize the clamping force of the semi-finished blank on the shaping ring during demolding; further, the number of ring segments is an even number, and the even number of ring segments are symmetrically arranged in pairs about the center of the shaping ring, and the circumferential lengths of any two ring segments symmetrically arranged about the center of the shaping ring are equal, so as to ensure that the supporting force for the semi-finished blank sleeved on the ring body is more balanced, so as to prevent the semi-finished blank sleeved on the ring body from being subjected to uneven force and deformation.

[0010] In one implementation, the number of the ring segments can also be two. In this case, in order to achieve radial movement of the ring segments, the circumferential length of one of the ring segments needs to be smaller than the circumferential length of the other ring segment. After the semi-finished blank is shaped, the ring segment with a smaller circumferential length can be driven to move toward the center of the shaping ring first, and the semi-finished blank is partially separated from the shaping ring, thereby reducing the holding force of the semi-finished blank on the shaping ring, and then demoulding is performed manually or mechanically to separate the semi-finished blank from the other ring segment with a longer circumferential length.

[0011] In one implementation, flanges are provided at the ends of the ring segments, and the flanges of two adjacent ring segments are stacked and detachably fixedly connected. It is understandable that when the radial cross-section of the ring segments is thick enough, or the flanges of two adjacent ring segments are stacked with high precision and without gaps, the flanges of the two adjacent ring segments preferably have a guide portion to ensure that the adjacent ring segments can be stacked or separated in the radial direction. The guide portion can be composed of one or more guide surfaces, or can include an arcuate surface, which is not particularly limited here.

[0012] In one implementation, the flanges of two adjacent ring segments are fixed by screws, which facilitates the disassembly and assembly of the two adjacent ring segments. It is understandable that there may be no mechanical connection structure between the two adjacent ring segments, and the two adjacent ring segments can be tightly connected only by external forces such as compression, which is also a detachable fixed connection.

[0013] In one implementation, the outer wall of the ring body is a smooth circular ring to ensure the accuracy of the shaping of the semi-finished blank; and / or the radial cross-section of the ring body is a square or trapezoidal shape with a regular shape for easy processing and manufacturing; and / or the material of the outer ring wall of the ring body includes metal or plastic; and / or the radial width of the ring body is 10mm to 200mm to ensure the mechanical strength of the ring body while saving raw materials; and / or the axial height of the ring body is 50mm to 500mm; and / or the inner diameter of the ring body is 200mm to 3000mm; and / or the outer diameter of the ring body is 300mm to 3000mm to accommodate semi-finished blanks of different models.

[0014] In one implementation, the semi-finished product is a sealing gasket for an electrolytic cell. Of course, the shaping ring provided in the present application is suitable for shaping any annular semi-finished product.

[0015] In one implementation, it also includes a radial support member, which is arranged on the inner side of the ring split to support the ring split on the inner side of the ring body to prevent the ring split from being deformed due to the clamping force of the semi-finished blank, thereby affecting the shaping accuracy of the semi-finished blank.

[0016] In one implementation, the radial support member includes a support rod, which can support the inner side of the ring split to prevent the ring body from being deformed due to the clamping force of the semi-finished blank.

[0017] In one implementation, the radial support member also includes a radial drive member, which can drive the support rod to move radially along the ring body, so that after the semi-finished blank is formed, the support rod can be moved radially, thereby facilitating the movement of the ring split to separate the ring split from the semi-finished blank.

[0018] In one implementation, the radial drive member includes a threaded sleeve, the support rod includes a threaded rod, the first end of the threaded rod is threadedly connected to the threaded sleeve, and the second end of the threaded rod is fixedly connected, abutted or rotationally connected to the ring body. In this way, the threaded rod can not only support the ring body, but also, in the process of rotating the threaded sleeve or the threaded rod, the threaded rod can be moved radially along the ring body, and then the threaded rod drives the ring body to move radially, so that the threaded rod drives the ring body to approach the center of the ring body or move away from the center of the ring body.

[0019] In one implementation, the threaded sleeve is a bidirectional threaded sleeve, the first ends of two threaded rods extending along the same radial direction of the ring body are respectively threadedly connected to the two ends of the bidirectional threaded sleeve, and the second ends of the two threaded rods are respectively fixedly connected to two radially opposite ring parts. Such a configuration is simple in structure and is more convenient for simultaneously driving more than two threaded rods and ring parts to move radially at the same time.

[0020] In one implementation, there are multiple threaded sleeves, so that multiple threaded sleeves can be used to drive multiple threaded rods to move radially, and then the multiple threaded rods can drive multiple ring splits to move radially. After the multiple ring splits are separated from the semi-finished billet, it is easier to remove the semi-finished billet after cooling and shaping; and / or, at least two threaded sleeves are axially perpendicular to each other, so that two circumferentially adjacent ring splits can be driven to move radially, so that the two circumferentially adjacent ring splits are separated from the semi-finished billet at the same time, which is convenient for removing the semi-finished billet from the above-mentioned two adjacent ring split positions; and / or, there are four threaded rods, and the four threaded rods are distributed in a cross shape. The four threaded rods can respectively drive the four ring splits to move radially, so that the four ring splits move simultaneously in a direction close to the center of the ring body, and the semi-finished billet can be removed after it is relaxed.

[0021] In one implementation, the second end of the threaded rod is separately welded to the ring, threadedly connected, interference-fitted and / or clamped, so as to facilitate processing and manufacturing.

[0022] In one implementation, the ring body is provided with an insertion hole, and the second end of the threaded rod is rotatably inserted into the insertion hole;

[0023] An axial limiter is also provided between the second end of the threaded rod and the inner wall of the socket. The function of the axial limiter is to prevent the threaded rod from being separated from the socket. In this way, the threaded rod can be moved radially by directly rotating the threaded rod, which is simple and convenient to operate.

[0024] In one implementation, the radial drive member includes a linear motor and / or a telescopic cylinder, which has a simple structure, is easy to operate and has a low cost. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] See also Figure 1-Figure 4 The shaping ring provided in the embodiment of the present application can be used to shape any annular semi-finished blank, and is particularly suitable for shaping the inner diameter of a sealing gasket blank. The shaping ring includes a ring body. The ring body is in a circular shape as a whole, and the ring body includes a plurality of ring segments 1. The plurality of ring segments 1 are connected in sequence along the circumference of the ring body, that is, the plurality of ring segments 1 are connected end to end in sequence to form a ring body, wherein the circumferential length of at least one of the ring segments is less than one half of the circumferential length of the ring body. Two adjacent ring segments 1 are detachably fixedly connected, that is, two adjacent ring segments 1 can be fixedly connected or detachably separated.

[0040] When the shaping ring provided by the utility model is used, first, multiple ring segments 1 are fixedly connected end to end in sequence to form a ring body, and the semi-finished blank after preliminary shaping is sleeved on the outside of the ring body, or in other words, the semi-finished blank after preliminary shaping is sleeved on the side of the ring body away from its center. After the semi-finished blank sleeved on the ring body is cooled and shaped, one or more ring segments 1 are driven to move radially toward the center of the shaping ring by manual or mechanical means, so that one or more ring segments 1 are separated from the semi-finished blank sleeved on the ring body, thereby reducing the clamping force of the semi-finished blank on the shaping ring, and facilitating the removal of the semi-finished blank from the position where the ring segment 1 is separated from the semi-finished blank. In addition, before cooling and shaping the next semi-finished blank, one or more ring segments 1 are driven to move radially toward the direction away from the center of the shaping ring by manual or mechanical means, and then multiple ring segments 1 are fixedly connected end to end in sequence to form a ring body.

[0041] As can be seen from the above, in the process of cooling and shaping the semi-finished blank using the shaping ring provided by the utility model, after the cooling and shaping is completed, one or more ring parts 1 are driven to move toward the center of the circle by manual or mechanical means, and the semi-finished blank can be directly taken out from the position where the ring parts 1 are separated from the semi-finished blank, which is convenient for operation and improves processing efficiency. Compared with the prior art, in which the semi-finished blank is pressed out of the shaping round tube by a molding machine, damage to the semi-finished blank can be prevented and the equipment cost is reduced.

[0042] The number of the ring segments 1 is preferably more than three, so that the clamping force of the semi-finished blank on the shaping ring can be minimized during demoulding.

[0043] It should be noted that the number of ring segments can also be two. At this time, in order to realize radial movement of the ring segments, the circumferential length of one of the ring segments needs to be smaller than the circumferential length of the other ring segment. After the semi-finished blank is formed, the ring segment with a smaller circumferential length can be driven toward the center of the forming ring first, and the semi-finished blank is partially separated from the forming ring, thereby reducing the clamping force of the semi-finished blank on the forming ring, and then manual or hydraulic or other mechanical demolding methods are used to separate the semi-finished blank from the other ring segment with a longer circumferential length.

[0044] The circumferential lengths of the multiple ring segments 1 are equal, so that the clamping force of the semi-finished blanks borne by the multiple ring segments 1 is more balanced, and it is not easy to deform the entire ring body. Of course, the circumferential lengths of the multiple ring segments 1 can also be unequal, which is not limited here.

[0045] Preferably, the number of the ring segments 1 can be an even number greater than three, and the even number of ring segments are symmetrically arranged in pairs about the center of the shaping ring, and the circumferential lengths of any two ring segments 1 symmetrically arranged about the center of the shaping ring are equal. This arrangement ensures that the support force for the semi-finished blank sleeved on the ring body is more balanced, and prevents the semi-finished blank sleeved on the ring body from being unevenly stressed and deformed. Exemplarily, the number of the ring segments 1 can be four, six, etc. Of course, the number of the ring segments 1 can also be an odd number, such as three, five, etc.

[0046] In addition, in order to facilitate the fixed connection of two adjacent ring parts 1, flanges 1a may be provided at the ends of the ring parts 1, and the flanges 1a of the two adjacent ring parts 1 are stacked and detachably fixedly connected. That is, in the two adjacent ring parts 1, the flange 1a of one ring part 1 is located on the inner side or outer side of the flange 1a of the other ring part 1, so that the flanges 1a of the two adjacent ring parts 1 are stacked, ensuring that the outer side wall of the ring body is a smooth circular ring, and ensuring the precision of the semi-finished blank shaping.

[0047] It should be noted that the flanges at both ends of at least one ring segment are located inside the flanges of the adjacent ring segment to ensure that at least one ring segment can move toward the center of the circle. For example, the three adjacent ring segments 1 are the first ring segment 1, the second ring segment 1 and the third ring segment 1, and the flanges 1a at both ends of the second ring segment 1 are located inside the flanges 1a of the first ring segment 1 and the third ring segment 1 adjacent thereto. Then, the second ring segment 1 can first move toward the center of the circle, and then the first ring segment 1 and the third ring segment 1 can move toward the center of the circle.

[0048] In addition, when the radial cross-section of the ring segments is thick enough, or the flanges of two adjacent ring segments are stacked with high precision and without gaps, the flanges of the two adjacent ring segments preferably have guide portions to ensure that the adjacent ring segments can be stacked or separated radially. Figure 5Several embodiments of the guide portion are shown. The guide portion 1d can be composed of one or more guide surfaces, so that the ring segment 1b can be stacked or separated from another ring segment 1c in the radial direction. Of course, the guide portion can also include an arcuate surface, which is not particularly limited here.

[0049] In the above embodiment, the flanges 1a of two adjacent ring segments 1 can be fixed by screws 4, which is convenient for disassembly and assembly. Alternatively, the flanges 1a of two adjacent ring segments 1 can also be detachably fixed in other ways, such as by snap-fitting.

[0050] Of course, two adjacent ring segments 1 can also be connected by means of slots and protrusions, which is not limited here. Alternatively, the flanges 1a of the two adjacent ring segments 1 may not have a mechanical connection structure, and only rely on external forces such as compression to achieve a tight connection between the two adjacent ring segments, which also belongs to a detachable fixed connection.

[0051] In another specific embodiment, the radial cross section of the ring body is square or trapezoidal, and the regular shape is convenient for processing and manufacturing. And the outer ring wall of the ring body is a curved surface extending along the ring, which is convenient for the semi-finished product blank to be sleeved on the outer side of the ring body. Of course, the cross section of the ring body can also be triangular, etc., which is not limited here.

[0052] The ring body may be made of metal or plastic, wherein the metal may include cast iron, carbon steel, aluminum, aluminum alloy, copper and / or copper alloy, and the plastic may be a composite material. The above materials may be used as long as the outer ring strength of the ring body is ensured.

[0053] If the radial width of the ring body is small, its mechanical strength is low and may not be able to bear the clamping force of the semi-finished blank; if the radial width of the ring body is too large, it may lead to waste of raw materials. Therefore, the radial width of the ring body is set within a reasonable range of 10mm to 200mm to ensure the mechanical strength of the ring body while saving raw materials. Exemplarily, the radial width of the ring body is 10mm, 50mm, 80mm, 100mm, 120mm, 150mm, 180mm or 200mm.

[0054] The height of the ring body along the axial direction can be 50 mm to 500 mm, so that after the semi-finished product blank is sleeved on the outside of the ring body, it is not easy to deviate from the ring body along the axial direction. Exemplarily, the height of the ring body along the axial direction is 50 mm, 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm or 500 mm.

[0055] The inner diameter of the ring body is 200 mm to 3000 mm. It can be set according to actual conditions. For example, the inner diameter of the ring body is 200 mm, 500 mm, 800 mm, 1000 mm, 1200 mm, 1500 mm, 1800 mm, 2000 mm, 2200 mm, 2500 mm, 2800 mm or 3000 mm.

[0056] Considering that the models of the semi-finished blanks are different and the inner diameters of the semi-finished blanks are different, the outer diameter of the ring body can be set according to actual needs. The outer diameter of the ring body can be 300mm to 3000mm to adapt to different models of semi-finished blanks. Exemplarily, the outer diameter of the ring body is 300mm, 500mm, 800mm, 1000mm, 1200mm, 1500mm, 1800mm, 2000mm, 2200mm, 2500mm, 2800mm or 3000mm.

[0057] like Figure 1 As shown, the shaping ring may also include a radial support member, which is arranged on the inner side of the ring body to support the ring body 1 on the inner side of the ring body to prevent the ring body from being deformed due to the clamping force of the semi-finished blank, thereby affecting the shaping accuracy of the semi-finished blank. In this embodiment, each ring body may be connected to the radial support member, or some of the ring bodies may be connected to the radial support member, which is not limited here.

[0058] Wherein, the radial support member may include a support rod, and the support rod may be fixedly connected, abutted or rotationally connected to the ring body 1. Specifically, the support rod contacts the inner side of the ring body 1 so that the support rod supports the ring body 1 from the inner side. The support rod and the inner side of the ring body 1 may only abut against each other, or the support rod and the inner side of the ring body 1 may also be fixedly connected by welding, threaded connection, interference fit and / or clamping. Of course, the support rod may also be rotationally connected to the ring body 1, the support rod may rotate around its own axis relative to the ring body 1, and the support rod supports the ring body 1 from the radial direction.

[0059] Furthermore, the radial support member also includes a radial drive member, which can drive the support rod to move radially along the ring body. Specifically, the radial drive member can drive the support rod to move in a direction close to the center of the ring body, and the radial drive member can also drive the support rod to move in a direction away from the center of the ring body. When the support rod is fixedly connected or rotationally connected to the ring split, the radial drive member can drive the support rod and the ring split 1 to move radially together; when the support rod abuts the ring split, the radial drive member drives the support rod to move in a direction close to the center of the ring body, and then the support rod is separated from the ring split 1, thereby separating the ring split 1 from the semi-finished blank, which is convenient for removing the semi-finished blank.

[0060] like Figure 1As shown, the radial drive member may include a threaded sleeve 3, and the support rod may include a threaded rod 2. The first end of the threaded rod 2 is threadedly connected to the threaded sleeve 3, that is, the first end of the threaded rod 2 and the threaded sleeve 3 can rotate relative to each other. The length direction of the threaded rod 2 is arranged along the radial direction of the ring body. The second end of the threaded rod 2 is fixedly connected to the ring body 1. In this arrangement, the threaded rod 2 can not only support the ring body 1, but also in the process of rotating the threaded sleeve 3, the threaded rod 2 can be moved radially along the ring body, and then the threaded rod 2 drives the ring body 1 to move radially, so that the threaded rod 2 drives the ring body 1 to move close to the center of the ring body or away from the center of the ring body. In this embodiment, the second end of the threaded rod 2 and the ring body 1 can be fixed together by welding, threaded connection, interference fit and / or clamping, which is convenient for processing and manufacturing.

[0061] Alternatively, the second end of the threaded rod 2 is rotatably connected to the ring body 1. In this embodiment, the threaded rod 2 can rotate around its own axis relative to the ring body 1, so that the threaded rod 2 can not only support the ring body 1, but also during the rotation of the threaded rod 2, the threaded rod 2 can also rotate while moving radially along the ring body, and then the threaded rod 2 drives the ring body 1 to move radially, so that the threaded rod 2 can drive the ring body 1 to approach the center of the ring body or move away from the center of the ring body, and the ring body 1 does not rotate with the threaded rod 2 but only moves radially with the threaded rod 2. In this embodiment, the ring body 1 can be provided with a socket, and the second end of the threaded rod 2 can be rotatably inserted into the socket, and an axial limiter is also provided between the second end of the threaded rod 2 and the inner wall of the socket. The function of the axial limiter is to prevent the threaded rod 2 from detaching from the socket. Specifically, the axial limiter can include an annular protrusion 2a and an annular groove, such as Figure 6 As shown, an annular protrusion 2a can be provided on the threaded rod 2 and an annular groove can be provided on the inner wall of the jack, or an annular groove can be provided on the threaded rod 2 and an annular protrusion 2a can be provided on the inner wall of the jack. The annular protrusion 2a is located inside the annular groove so that the threaded rod 2 can rotate relative to the ring body 1 without being separated from the jack. Alternatively, the second end of the threaded rod 2 can also be connected to the ring body 1 by a pin shaft, and it is only necessary to ensure that the threaded rod 2 can rotate relative to the ring body 1 and drive the ring body 1 to move radially.

[0062] Alternatively, the second end of the threaded rod 2 may only abut against the ring body 1, that is, the second end of the threaded rod 2 only contacts the ring body 1 without being fixedly connected or rotationally connected, so that the threaded rod 2 supports the ring body 1 to prevent the ring body 1 from displacement and deformation.

[0063] In the above embodiments, Figure 3 and Figure 4As shown, the threaded sleeve 3 can be a bidirectional threaded sleeve, and the first ends of the two threaded rods 2 extending along the same radial direction of the ring body are respectively threadedly connected to the two ends of the bidirectional threaded sleeve, and the second ends of the two threaded rods 2 are respectively fixedly connected to the two ring segments 1 arranged symmetrically about the center of the shaping ring. Specifically, the first ends of the two threaded rods 2 with the same extension direction are respectively threadedly connected to the two ends of the same bidirectional threaded sleeve, and in the process of rotating the bidirectional threaded sleeve, the two threaded rods 2 simultaneously move in the direction close to the center of the ring body, so as to drive the ring segment 1 connected to the two threaded rods 2 to move in the direction close to the center of the ring body and separate from the semi-finished blank. In the process of rotating the bidirectional threaded sleeve in the opposite direction, the two threaded rods 2 simultaneously move in the direction away from the center of the ring body, so as to drive the ring segment 1 connected to the two threaded rods 2 to move in the direction away from the center of the ring body, so that multiple ring segments 1 can be connected end to end. Such a configuration has a simple structure and is more convenient for simultaneously supporting two ring segments 1 and simultaneously driving more than two threaded rods 2 and ring segments 1 to move radially.

[0064] In a preferred embodiment, the number of threaded sleeves 3 is multiple, so that the multiple threaded sleeves 3 can be used to drive the multiple threaded rods 2 to move radially, and then the multiple threaded rods 2 drive the multiple ring segments 1 to move radially. After the multiple ring segments 1 are separated from the semi-finished blank, it is more convenient to remove the semi-finished blank after cooling and shaping. Exemplarily, the number of threaded sleeves 3 can be two, three, four or more, and of course, the number of threaded sleeves 3 can also be only one.

[0065] Specifically, at least two threaded sleeves 3 can be axially perpendicular to each other, that is, at least two threaded rods 2 can be perpendicular to each other. The two threaded rods 2 that are perpendicular to each other can simultaneously support two circumferentially adjacent ring segments 1, and can also drive the two circumferentially adjacent ring segments 1 to move radially, so that the two circumferentially adjacent ring segments 1 are separated from the semi-finished blank at the same time, making it easy to remove the semi-finished blank from the above-mentioned two adjacent ring segments 1. Of course, the angle between the axial directions of any two threaded sleeves 3 can also be an acute angle, for example, the angle between the axial directions of any two threaded sleeves 3 can be 30° or 45°, which is not limited here.

[0066] like Figure 1 and Figure 2 As shown, the number of threaded rods 2 is four, and the four threaded rods 2 are distributed in a cross shape. In this embodiment, the number of ring segments 1 is four, and the lengths of the four ring segments 1 along the circumferential direction are equal, that is, the ring body is divided into four equal parts. The four threaded rods 2 can support the four ring segments 1 respectively. And the four ring segments 1 can be driven to move radially respectively, so that the four ring segments 1 move toward the center of the ring body at the same time, and the semi-finished blank can be removed after being relaxed. Of course, the four threaded rods 2 can be arranged arbitrarily in other ways, which is not limited here.

[0067] According to actual needs, the length of the threaded rod 2 is 300 mm to 3000 mm. Considering that the models of the semi-finished blanks are different and the inner diameters of the semi-finished blanks are different, the length of the threaded rod 2 can be set according to actual needs. Exemplarily, the length of the threaded rod 2 can be 300 mm, 500 mm, 800 mm, 1000 mm, 1200 mm, 1500 mm, 1800 mm, 2000 mm, 2200 mm, 2500 mm, 2800 mm or 3000 mm.

[0068] In addition, if the threaded rod 2 is too thin, the mechanical strength may be low and cannot support the clamping force of the semi-finished blank on the ring body. If the threaded rod 2 is too thick, it may lead to waste of raw materials. Therefore, the cross-sectional area of ​​the threaded rod 2 is set at 5mm 2 ~100mm 2 The cross-sectional area of ​​the threaded rod 2 is within a reasonable range to ensure the mechanical strength of the threaded rod 2 and reduce the manufacturing cost. 2 , 10mm 2 , 20mm 2 , 30mm 2 , 40mm 2 , 50mm 2 、60mm 2 、70mm 2 、80mm 2 、90mm 2 or 100mm 2 wait.

[0069] In another embodiment, the radial driving member may include a linear motor, a telescopic cylinder, etc. Specifically, the linear motor and the telescopic cylinder may be used to drive the ring body 1 to move radially, and the telescopic direction of the linear motor and the telescopic cylinder may be arranged along the radial direction of the ring body. Such an arrangement has a simple structure, is easy to operate, and has a low cost.
