It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0034] In one aspect, an embodiment of the present application provides a clamping device installed on a splitting shearing machine, the clamping device comprising: a support 1, the support 1 being used for fixed connection with a fixed side of the splitting shearing machine and being used for sliding connection with a moving side 3 of the splitting shearing machine; at least one clamping assembly 2, the clamping assembly 2 being used for being placed between inlet clamping rollers and outlet clamping rollers of the splitting shearing machine and being installed on the support 1, the clamping assembly 2 comprising two clamping pieces 21, the two clamping pieces 21 being arranged in an upper and lower interval and being used for approaching or moving away from each other to limit the wide and thick plate on the fixed side.

[0035] It should be noted that, as shown in Figure 1 the upper and lower interval arrangement is an interval arrangement along the Z axis direction.

[0036] It should be noted that, as shown in Figure 1As shown, the splitting shear machine is divided into a moving side 3 and a fixed side, the rack of the moving side 3 can reciprocate relative to the fixed side along the width direction of the wide-thick plate, that is, the Y-axis direction, so as to adjust the position of the lower shear table 5 on the rack of the moving side 3, and realize the splitting of the wide-thick plate into different widths; and the rack of the moving side 3 is composed of an inlet side upper rack body 31, an inlet side lower rack body 32, an outlet side upper rack body 33, an outlet side lower rack body 34 and a lifting roller table 35, wherein the inlet side upper rack body 31 and the inlet side lower rack body 32 are arranged in an upper and lower interval to form an entrance of the wide-thick plate, the outlet side upper rack body 33 and the outlet side lower rack body 34 are arranged in an upper and lower interval to form an exit of the wide-thick plate, the wide-thick plate enters the rack of the moving side 3 from the entrance, is clamped by the entrance clamping roller, and is moved out of the rack of the moving side 3 by the exit, is clamped by the exit clamping roller, and is finally output, and when the wide-thick plate is split, the lifting roller table 35 can move up and down, the upper shear blade on the rack of the moving side 3 can move up and down, and when the wide-thick plate is split, the upper shear blade moves down and cooperates with the lifting roller table 35 to limit and support the moving side wide-thick plate during splitting, so that the moving side wide-thick plate is basically stable during splitting. However, only the fixed roller table 4 is arranged below the fixed side wide-thick plate, and the fixed roller table 4 can only support the bottom wall of the fixed side wide-thick plate at a fixed position, so that the fixed side wide-thick plate is prone to swing during splitting, causing the cut to bend, and even forming a step, thereby seriously affecting the shearing quality of the wide-thick plate.

[0037] Therefore, as Figure 1 shown, in the present embodiment, a support 1 is provided as a support structure of the clamping device, the support 1 can be fixedly connected with the fixed side of the splitting shear machine, so as to ensure the installation stability of the support 1, and the support 1 can also be slidingly connected with the moving side 3 of the splitting shear machine, so that part of the support 1 can be placed at the moving side 3, making the structure of the splitting shear machine more compact, and when the moving side 3 slides relative to the fixed side, the moving side 3 can support the support 1, so that the support 1 can remain stable when the moving side 3 moves. On this basis, a clamping assembly 2 is further arranged between the entrance clamping roller and the exit clamping roller of the splitting shear machine, the clamping assembly 2 is installed on the support 1, which not only ensures the stability of the clamping assembly 2, but also enables the fixed side wide-thick plate to pass through the clamping assembly 2, and the clamping assembly 2 is composed of two clamping pieces 21 arranged in an upper and lower interval, the two clamping pieces 21 can move close to or away from each other, when the fixed side wide-thick plate passes through the clamping assembly 2, the fixed side wide-thick plate can pass between the two clamping pieces 21, at this time, the two clamping pieces 21 can move close to each other and fit the top wall and the bottom wall of the wide-thick plate respectively, so as to limit the fixed side wide-thick plate during splitting, avoid the fixed side wide-thick plate from swinging during splitting, improve the stability of the fixed side wide-thick plate during splitting, and further improve the shearing quality of the wide-thick plate.

[0038] It should be noted that, in the present embodiment, as Figure 1 and Figure 2As shown, the bracket 1 is composed of a support column 11 and a guide beam 12, wherein one end of the support column 11 is fixedly connected with the fixed side, and the other end is fixedly connected with the guide beam 12, the guide beam 12 is used for mounting the clamping assembly 2, and the mounting stability of the clamping assembly 2 is ensured, and the two side walls of the guide beam 12 along the moving direction of the wide and thick plate, that is, the Y-axis direction are respectively slidably connected with the inner walls of the inlet side upper frame body 31 and the outlet side upper frame body 33, and the stability of the bracket 1 relative to the moving side 3 is ensured.

[0039] It should be noted that, as Figure 3 shown, a stopper is arranged on the side wall of the horizontal plate of the guide beam 12, and when the clamping piece 21 moves towards the horizontal plate, the stopper can abut against the clamping piece 21, and the movement limit of the clamping piece 21 towards the horizontal plate is limited, wherein the surface shapes of the upper and lower two side walls of the stopper are matched with the movement path of the central axis of the clamping piece 21, so as to support the clamping piece 21 when the clamping piece 21 moves, and the stopper is connected with the vertical plate of the guide beam 12, so as to form an integral whole with the guide beam 12, and the structural stability is ensured.

[0040] It should be noted that, as Figure 2 shown, in the embodiment, two clamping assemblies 2 are arranged, and the two clamping assemblies 2 are arranged at intervals along the moving direction of the wide and thick plate, so as to further improve the limiting effect on the fixed side wide and thick plate by clamping the fixed side wide and thick plate at multiple points, and avoid the swing of the fixed side wide and thick plate when being split.

[0041] Optionally, the clamping assembly 2 further comprises a rocker arm 22 and a telescopic driving piece 23, the middle segments of the two rocker arms 22 arranged above and below are respectively connected with the clamping piece 21, one end of the rocker arm 22 is hinged with the bracket 1, and the other ends of the telescopic driving piece 23 are respectively hinged with the other ends of the two rocker arms 22 arranged above and below.

[0042] In order to ensure the stability of the two clamping pieces 21 moving close to each other or moving away from each other, as Figure 1 and Figure 2As shown, in the embodiment, the clamping assembly 2 is further provided with a rocker arm 22 and a telescopic driving member 23, wherein the middle section of the rocker arm 22 is connected with the side wall of the clamping piece 21, one end of the rocker arm 22 is hinged with the support 1, and the other ends of the telescopic driving member 23 are hinged with the other ends of the upper and lower rocker arms 22, respectively. In this way, when the telescopic driving member 23 is extended or shortened, the rocker arm 22 can rotate around the hinge with the support 1, so as to swing upward or downward, thereby driving the clamping piece 21 to move upward or downward, and realizing the mutual approaching or moving away of the clamping pieces 21. The end of the telescopic driving member 23 is hinged with the end of the rocker arm 22, and the rocker arm 22 and the telescopic driving member 23 relatively rotate while the rocker arm 22 swings, so that the telescopic driving member 23, the upper and lower rocker arms 22 and the support 1 form a four-bar linkage structure, the structure change of the four-bar linkage is realized by the extension and contraction of the telescopic driving member 23, the structural stability is relatively high, and the motion stability of the clamping piece 21 is improved.

[0043] It should be noted that, in the embodiment, as Figure 2 shown, the guide beam 12 of the support 1 is in an I-shaped structure, which is composed of vertical plates and a horizontal plate. The two vertically arranged vertical plates are slidably connected with the moving side 3, and the horizontal plate is located between the two vertical plates. The two ends of the horizontal plate are connected with the vertical plates, respectively. The two clamping pieces 21 and the two rocker arms 22 are located on the upper and lower sides of the horizontal plate, respectively. The rocker arm 22 is hinged with the vertical plate. The horizontal plate is provided with a strip-shaped hole, and the telescopic driving member 23 passes through the strip-shaped hole. When the telescopic driving member 23 is extended or shortened, the distance between the telescopic driving member 23 and the vertical plate changes due to the swinging of the rocker arm 22. The strip-shaped hole allows the telescopic driving member 23 to slide, so as to ensure the normal swinging of the rocker arm 22, and further ensure the stability of the upward and downward movement of the clamping piece 21. In addition, in order to ensure the structural stability of the guide beam 12, a diagonal bracing plate is arranged between the vertical plate and the horizontal plate, and a rib plate extending along the length direction is arranged on the horizontal plate.

[0044] It should be noted that, in the embodiment, the telescopic driving member 23 is a hydraulic cylinder.

[0045] Optionally, the clamping assembly 2 further comprises a limiting frame 24, which is installed on the support 1, and the two clamping pieces 21 pass through the limiting frame 24.

[0046] In order to ensure the clamping stability of the clamping piece 21, as Figure 3As shown, the clamping assembly 2 is also provided with a limiting frame 24, the limiting frame 24 is installed on the support 1, and the two clamping pieces 21 pass through the limiting frame 24, so that when the clamping pieces 21 are close to each other or away from each other, the inner wall of the limiting frame 24 can limit the clamping pieces 21, avoiding the dislocation of the clamping pieces 21, and when the clamping pieces 21 are attached to the fixed side wide thick plate and are cut, the fixed side wide thick plate has a tendency to swing up and down, and the force generated by the tendency tends to move the clamping pieces 21 towards the limiting frame 24, at this time, the limiting frame 24 can limit the clamping pieces 21, thereby ensuring the stability of the limiting of the fixed side wide thick plate.

[0047] It should be noted that, as Figure 3 shown, the limiting frame 24 is composed of two horizontal limiting blocks and two vertical limiting columns, the two horizontal limiting blocks are respectively located on the upper and lower sides of the horizontal plate of the guide beam 12, the vertical limiting column can pass through the horizontal plate, and the two ends are respectively connected with the two horizontal limiting blocks, the two clamping pieces 21 are located between the two vertical limiting columns and between the upper and lower horizontal limiting blocks and the horizontal plate.

[0048] Optionally, the clamping assembly 2 further comprises an elastic member 25, the elastic member 25 is arranged in the vertical direction, and the two ends of the elastic member 25 are respectively connected with the limiting frame 24 and the clamping piece 21.

[0049] It should be noted that, as Figure 3 shown, the vertical direction is the Z-axis direction.

[0050] In order to offset the force of the fixed side wide thick plate during cutting, in the embodiment, as Figure 3 shown, the clamping assembly 2 is also provided with an elastic member 25, the elastic member 25 is arranged in the vertical direction, and the two ends of the elastic member 25 are respectively connected with the limiting frame 24 and the clamping piece 21, so that when the force of the fixed side wide thick plate acts on the clamping piece 21, the clamping piece 21 transmits the force to the elastic member 25, and the elastic member 25 gives the clamping piece 21 an opposite force after being subjected to the force, thereby ensuring the stability of the limiting of the fixed side wide thick plate by the clamping piece 21. Moreover, the elastic member 25 has a compression limit, which can also limit the movement limit of the clamping piece 21.

[0051] It should be noted that, in the embodiment, the elastic member 25 is a disc spring.

[0052] It should be noted that, in the embodiment, the elastic member 25 is installed only on the horizontal limiting block on the lower side of the horizontal plate of the limiting frame 24, and the limit of the downward movement of the clamping piece 21 located below is limited, while the limit of the upward movement of the upper clamping piece 21 is limited by the horizontal limiting block on the upper side of the horizontal plate.

[0053] Optionally, the clamping assembly 2 further comprises an adjusting seat 26, and the side wall of the clamping piece 21 is provided with a connecting block 211, the connecting block 211 is hinged to the adjusting seat 26, and the adjusting seat 26 is obliquely installed on the support 1, so that the two ends of the two clamping pieces 21 for limiting the fixed side wide plate are close to each other.

[0054] Specifically, the two ends of the two clamping pieces 21 for limiting the fixed side wide plate are close to each other, that is, the two ends of the two clamping pieces 21 for clamping and limiting are relatively close.

[0055] In order to improve the service life of the clamping device, in the embodiment, as shown in the figure, Figure 3 the clamping assembly 2 is further provided with an adjusting seat 26, the adjusting seat 26 is installed on the support 1, the adjusting seat 26 is hinged to the connecting block 211 on the side wall of the clamping piece 21, so that the connecting block 211 swings relative to the adjusting seat 26 when the clamping piece 21 moves up and down, further improving the movement stability of the clamping piece 21. On this basis, the adjusting seat 26 is obliquely installed on the support 1, so that the clamping piece 21 is driven to be inclined by the connecting block 211, so that the two clamping pieces 21 are close to each other at one end of the moving side 3. After the fixed side wide plate is fitted with the clamping piece 21, the fixed side wide plate will generate a reverse force on the clamping piece 21 when it is split, so that the two clamping pieces 21 are away from each other at one end of the moving side 3. Due to the oblique arrangement of the adjusting seat 26, the clamping piece 21 is inclined in advance, so that the pre-tilt of the clamping piece 21 and the tilt caused by the reaction force of the fixed side wide plate are offset, so that the clamping piece 21 remains in a horizontal state, which not only ensures the limiting effect of the fixed side wide plate, but also avoids the structural deformation caused by the reaction force of the fixed side wide plate, and improves the service life of the clamping device.

[0056] It should be noted that, as shown in Figure 3 and Figure 4 the adjusting seat 26 is installed on the inner wall of the vertical plate, in order to ensure the inclination of the adjusting seat 26, a wedge key 261 is further provided, the wedge key 261 is fixed on the inner wall of the vertical plate of the guide beam 12 and provides an inclined supporting surface, and the adjusting seat 26 is supported on the wedge key 261, so that the wedge key 261 provides vertical support for the obliquely arranged adjusting seat 26, ensuring the installation stability of the adjusting seat 26.

[0057] Optionally, the clamping piece 21 is a cylindrical structure, and the circumferential surface of the cylindrical structure is used to fit with the upper end surface or the lower end surface of the wide plate.

[0058] In order to ensure the stable movement of the fixed side wide plate, as shown in Figure 2 and Figure 3As shown, the clamping piece 21 is provided in a cylindrical structure, wherein when the clamping piece 21 limits the fixed side wide plate, the circumferential surface of the cylindrical structure can be in close contact with the upper end surface or the lower end surface of the wide plate, so as to ensure that the clamping piece 21 limits the fixed side wide plate, and at the same time, the contact area between the clamping piece 21 and the fixed side wide plate is reduced, so as to reduce the friction force suffered by the fixed side wide plate during movement, and ensure the stable movement of the fixed side wide plate.

[0059] Optionally, the clamping piece 21 comprises a moving column 212 and a clamping column 213, the moving column 212 and the clamping column 213 are coaxially arranged, the moving column 212 is connected with the rocker arm 22, and the clamping column 213 is rotatably installed at the end of the moving column 212, and the circumferential surface of the clamping column 213 is used to be in close contact with the upper end surface or the lower end surface of the wide plate.

[0060] In order to further ensure the stable movement of the fixed side wide plate, as shown in Figure 2 and Figure 3 , the clamping piece 21 is composed of the coaxially arranged moving column 212 and clamping column 213, wherein the moving column 212 is connected with the rocker arm 22, and the clamping column 213 is rotatably installed at the end of the moving column 212, and the circumferential surface of the clamping column 213 can be in close contact with the upper end surface or the lower end surface of the wide plate when the clamping piece 21 limits the fixed side wide plate. By such arrangement, the friction mode between the fixed side wide plate and the clamping piece 21 during movement can be changed from sliding friction to rolling friction through the rotation of the clamping column 213, the friction force suffered by the fixed side wide plate during movement is further reduced, and the stable movement of the fixed side wide plate is ensured.

[0061] It should be noted that in the embodiment, the clamping piece 21 is a guide roller.

[0062] Optionally, the clamping device further comprises a guide groove 6, the guide groove 6 is arranged on the moving side 3, and the support 1 is provided with a wheel 121 which is arranged in the guide groove 6.

When the support 1 and the moving side 3 move relatively, the wheel 121 rolls along the guide groove 6, which not only ensures the direction stability of the relative sliding between the moving side 3 and the support 1, but also reduces the friction force between the moving side 3 and the support 1 during relative sliding in the form of rolling friction, thereby improving the stability.

[0064] It should be noted that, in the embodiment, as shown in Figure 3 and Figure 5 The guide groove 6 extends along the moving direction of the moving side 3 and is arranged on the inlet side upper frame body 31 and the outlet side upper frame body 33, and the wheel 121 is installed on the two vertical plates of the guide beam 12 of the support 1.
