Description

Technical Field

[0001] This utility model relates to the field of water pipe clamping technology, and in particular to a clamping device for spray water pipes on the upper roll of a short-stress rolling mill. Background Technology

[0002] Short-stress rolling mills are widely used in the rolling of metals such as bars and wires due to their high rolling precision and large roll system rigidity. During the rolling process, cooling liquid is sprayed from water pipes to cool the upper rolls of the short-stress rolling mill in order to ensure the roll life and the quality of the rolled products.

[0003] The related technology includes a Chinese patent with authorization announcement number CN218014888U, which provides a universal water pipe bracket for rolling mills. It includes a crossbeam, a first bracket, and a second bracket. A crossbeam waist-shaped through hole is formed on the crossbeam, and a first through hole is formed on the first bracket. One end of a first bolt is slidably engaged with the crossbeam waist-shaped through hole and the first through hole, respectively. One end of the first bolt passes through the crossbeam waist-shaped through hole and the first through hole in sequence. A first nut is threadedly connected to the first bolt to lock the first bracket onto the crossbeam. A second nut is threadedly connected to the second bolt to lock the second bracket onto the first bracket. The second bracket is used for fixed connection with the water pipe. The first bolt is passed through the first through hole and the crossbeam waist-shaped through hole in sequence. Then, the first nut is screwed onto the rear end of the first bolt without keeping it tightened. The first bolt is slid along the length of the crossbeam waist-shaped through hole, which drives the first bracket to slide to a suitable position. Then, the first nut is tightened to fix the first bracket to the crossbeam. The second bolt is passed through the second waist-shaped through hole and the first waist-shaped through hole in sequence. When the distance between the tube body and the roll is adjusted to a suitable distance, the second bolt is tightened to fix the first bracket to the second bracket.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: the first bracket and the crossbeam are fixed by the first bolt and the first nut. Since the clamping force formed by the first bolt and the first nut is concentrated in a local area, the connection point between the first bracket and the crossbeam is prone to cracking and deformation under long-term load, which increases the risk of loosening of the connection between the first bracket and the crossbeam, thereby affecting the positioning accuracy of the sprinkler pipe. Utility Model Content

[0005] To reduce the risk of loosening of the connection between the first support and the crossbeam, and to minimize the decrease in the positioning accuracy of the spray water pipe, this application provides a clamping device for the spray water pipe of the upper roll of a short-stress rolling mill.

[0006] The clamping device for the spray water pipe on the upper roll of a short-stress rolling mill provided in this application adopts the following technical solution: A clamping device for a spray water pipe on the upper roll of a short-stress rolling mill includes a first bracket, a second bracket mounted on the first bracket, an upper support mounted on the first bracket, and a lower support mounted on the side of the upper support away from the first bracket. A first component and a second component are disposed between the upper support and the lower support. The first component is used to pre-fix the upper support and the lower support, and the second component is used to lock the upper support and the lower support. An upper through groove is formed on the side of the upper support facing the lower support, and the upper through groove penetrates both end walls of the upper support. A lower through groove is formed on the side of the lower support facing the upper support, and the lower through groove penetrates both end walls of the lower support. The upper through groove and the lower through groove are arranged opposite to each other.

[0007] By adopting the above technical solution, the first bracket is installed on the crossbeam, and the second bracket is connected to the spray pipe. Adjusting the relative positions of the first and second brackets achieves the effect of adjusting the relative position of the spray pipe and the upper roller. When installing the first bracket on the crossbeam, the upper support is positioned above the crossbeam, and the lower support is positioned below the crossbeam, so that the crossbeam is inserted into the oppositely positioned upper and lower through slots. Then, the upper and lower supports are pre-fixed using the first component. Afterward, the upper and lower supports move synchronously along the crossbeam, causing the first bracket to slide to a suitable position, so that the center arc of the spray pipe is aligned with the required position of the upper roller. Finally, the second component locks the upper and lower supports on the cooling center circle, clamping the crossbeam between them. The upper and lower supports wrap around the crossbeam, and the crossbeam and the first bracket form a large-area surface contact pressing structure through the upper and lower supports. The clamping force of the second component is distributed through the upper and lower supports on the contact area between the upper and lower supports and the crossbeam, replacing the point contact pressing structure between the crossbeam and the first bracket. This reduces the concentration of the connection strength between the crossbeam and the first bracket in a local area, reduces the risk of loosening of the connection between the first bracket and the crossbeam, and reduces the decrease in the positioning accuracy of the spray pipe.

[0008] Preferably, both the inner walls of the upper and lower through grooves are provided with elastic layers.

[0009] By adopting the above technical solution, when the upper support and the lower support clamp the crossbeam, the elastic layer abuts against the upper support, the lower support and the crossbeam. The slight elastic deformation of the elastic pad compensates for the installation error during the clamping process. At the same time, the elastic layer increases the friction between the upper support, the lower support and the crossbeam, and improves the stability of the connection between the first bracket and the crossbeam.

[0010] Preferably, the first component includes a pin, a lower protrusion, and a set of upper protrusions. The upper protrusions are fixedly disposed on the side of the upper support away from the first bracket, and the lower protrusions are fixedly disposed on the side of the lower support facing the upper support. The lower protrusions are inserted between the upper protrusions, and the opposite surfaces of the upper protrusions abut against the end walls of the lower protrusions. The end walls of the upper protrusions are provided with an upper through hole, and the end walls of the lower protrusions are provided with a lower through hole. The upper through hole and the lower through hole are arranged opposite to each other. The pin passes through the upper through hole and the lower through hole. The inner wall of the upper through hole fits against the outer wall of the pin, and the inner wall of the lower through hole fits against the outer wall of the pin.

[0011] By adopting the above technical solution, when pre-fixing the upper support and the lower support, the upper through groove and the lower through groove are first set opposite to each other, then the lower protrusion is inserted between the upper protrusion, and then the pin is passed through the upper through hole and the lower through hole, thereby achieving the effect of pre-fixing the upper support and the lower support.

[0012] Preferably, a set of pin holes are formed through the side wall of the pin shaft, and cotter pins are inserted into the pin holes, with the upper protrusion located between the cotter pins.

[0013] By adopting the above technical solution, after the pin passes through the upper and lower through holes, the cotter pin passes through the pin hole, making it difficult for the pin to fall out of the upper and lower through holes.

[0014] Preferably, the second component includes a plurality of locking bolts and a plurality of locking nuts. The upper support has a plurality of upper threaded holes, and the lower support has a plurality of lower threaded holes. The upper threaded holes and the lower threaded holes are arranged opposite to each other. The locking bolts pass through the upper threaded holes and the lower threaded holes. The locking bolts and the locking nuts are threadedly connected. The end of the locking bolt abuts against the side of the upper support away from the lower support, and the locking nut abuts against the side of the lower support away from the upper support.

[0015] By adopting the above technical solution, when locking the upper support and the lower support, the locking bolt passes through the upper screw hole and the lower screw hole, and then the locking nut is tightened on the locking bolt, so that the end of the locking bolt abuts against the side of the upper support away from the lower support, and the locking nut abuts against the side of the lower support away from the upper support, thereby achieving the effect of locking the upper support and the lower support.

[0016] Preferably, a flat washer is fitted onto the locking bolt, and the flat washer abuts against the lower support and the locking nut.

[0017] By adopting the above technical solution, when the locking nut is tightened on the locking bolt, the flat washer abuts between the lower support and the locking nut, dispersing the pressure of the locking nut on the surface of the lower support and reducing the damage to the surface of the lower support.

[0018] Preferably, a plurality of first grooves are formed through the first bracket, a first slider is slidably disposed in the first groove, a first locking component is disposed between the first slider and the first bracket, the first locking component is used to fix the first slider, a second slider is rotatably disposed on the first slider, a second groove is formed through the second bracket, the second slider is slidably disposed in the second groove, a second locking component is disposed on the second bracket, the second locking component is used to fix the second slider.

[0019] By adopting the above technical solution, when adjusting the concentricity of the spray pipe and the upper roller, the first slider is first moved to a suitable position along the first slide groove, and then the first locking component is used to fix the first slider so that the spray pipe and the upper roller are concentric, achieving the effect of equidistant distance between each nozzle on the spray pipe and the upper roller. When adjusting the distance between the spray pipe and the upper roller, the second bracket and the second slider are first moved relative to each other, and then the second locking component is used to fix the second slider, achieving the effect of adjusting the distance between the spray pipe and the upper roller.

[0020] Preferably, the first locking assembly includes a first screw and a set of first nuts. The first screw is fixedly disposed in the first slide groove and passes through the first slider. The first slider is slidably connected to the first screw. The first nuts are threadedly connected to the first screw, and the opposite surface of the first nuts is used to abut against the end wall of the first slider.

[0021] By adopting the above technical solution, when the first slider is fixed in the first groove, the first nut is rotated so that the opposite surface of the first nut abuts against the end wall of the first slider.

[0022] Preferably, the second locking assembly includes a second screw and a plurality of second nuts. The second screw is fixedly disposed in the second slide groove and passes through the second slider. The second slider is slidably connected to the second screw. The second nuts are threadedly connected to the second screw, and the opposite surfaces of the second nuts are used to abut against the end wall of the second slider.

[0023] By adopting the above technical solution, when the second block is fixed in the second slide groove, the second nut is rotated so that the opposite surface of the second nut abuts against the end wall of the second slider.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a first bracket, a second bracket, an upper support, a lower support, a first component, a second component, an upper through groove, and a lower through groove, the upper and lower supports wrap around the crossbeam. The crossbeam and the first bracket form a large-area surface contact pressing structure through the upper and lower supports. The clamping force of the second component is distributed through the upper and lower supports on the contact area between the upper and lower supports and the crossbeam, replacing the point contact pressing structure between the crossbeam and the first bracket. This reduces the concentration of the connection strength between the crossbeam and the first bracket in a local area, reduces the risk of loosening of the connection between the first bracket and the crossbeam, and reduces the decrease in the positioning accuracy of the spray pipe. 2. By setting pins, lower protrusions, upper protrusions, upper through holes, and lower through holes, the upper and lower supports are pre-fixed. 3. By setting locking bolts, locking nuts, upper screw holes, and lower screw holes, the upper support and lower support can be locked together. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a clamping device for the spray water pipe of the upper roll of a short-stress rolling mill. (Refer to...) Figures 1 to 3The system includes a first support 1, on which a second support 2 is mounted. An upper support 3 is welded to the first support 1, and a lower support 4 is mounted on the side of the upper support 3 away from the first support 1. An upper through groove 31 is formed on the side of the upper support 3 facing the lower support 4, penetrating both end walls of the upper support 3; a lower through groove 41 is formed on the side of the lower support 4 facing the upper support 3, penetrating both end walls of the lower support 4. The upper through groove 31 and the lower through groove 41 are positioned opposite each other, and both inner walls are covered with an elastic layer 7 of rubber. A first component 5 and a second component 6 are installed between the upper support 3 and the lower support 4. The first component 5 is used to pre-fix the upper support 3 and the lower support 4, and the second component 6 is used to lock the upper support 3 and the lower support 4. The first support 1 is mounted on a crossbeam, and the second support 2 is connected to a spray pipe. By adjusting the relative positions of the first support 1 and the second support 2, the relative position of the spray pipe and the upper roller can be adjusted. When installing the first bracket 1 onto the crossbeam, the upper support 3 is positioned above the crossbeam, and the lower support 4 is positioned below the crossbeam, so that the crossbeam is inserted into the oppositely arranged upper through groove 31 and lower through groove 41. Then, the upper support 3 and lower support 4 are pre-fixed using the first component 5. Next, the upper support 3 and lower support 4 are moved synchronously along the crossbeam, causing the first bracket 1 to slide to a suitable position, so that the center arc of the spray pipe is aligned with the center circle of the upper roller that needs cooling. Finally, the second component 6 is used to lock the upper support 3 and lower support 4, clamping the crossbeam between them, with the elastic layer 7 abutting between the upper support 3, lower support 4, and the crossbeam. The slight elastic deformation of the elastic pad compensates for installation errors during clamping, while the elastic layer 7 increases the friction between the upper support 3, lower support 4, and the crossbeam, improving the stability of the connection between the first bracket 1 and the crossbeam. The upper support 3 and the lower support 4 wrap around the crossbeam. The crossbeam and the first bracket 1 form a large-area surface contact pressing structure through the upper support 3 and the lower support 4. The clamping force of the second component 6 will be distributed through the upper support 3 and the lower support 4 on the contact area between the upper support 3 and the lower support 4 and the crossbeam, replacing the point contact pressing structure between the crossbeam and the first bracket 1. This reduces the situation where the connection strength between the crossbeam and the first bracket 1 is concentrated in a local area, reduces the risk of loosening of the connection between the first bracket 1 and the crossbeam, and reduces the decrease in the positioning accuracy of the spray pipe.

[0035] Reference Figures 1 to 4The first component 5 includes a pin 51, a lower protrusion 52, and a set of upper protrusions 53. The upper protrusions 53 are mounted on the side of the upper support 3 away from the first bracket 1, and the lower protrusions 52 are mounted on the side of the lower support 4 facing the upper support 3. The lower protrusions 52 are inserted between the upper protrusions 53, with the opposite surfaces of the upper protrusions 53 abutting against the end walls of the lower protrusions 52. An upper through hole 531 is formed through the end wall of the upper protrusions 53, and a lower through hole 521 is formed through the end wall of the lower protrusions 52; the upper through holes 531 and 521 are opposite to each other. The pin 51 passes through the upper through hole 531 and the lower through hole 521; the inner wall of the upper through hole 531 fits against the outer wall of the pin 51, and the inner wall of the lower through hole 521 fits against the outer wall of the pin 51. A set of pin holes 511 are formed through the side wall of the pin 51, and cotter pins 512 are inserted into the pin holes 511; the upper protrusions 53 are located between the cotter pins 512. When pre-fixing the upper support 3 and the lower support 4, first align the upper through groove 31 and the lower through groove 41, then insert the lower protrusion 52 between the upper protrusions 53, and then pass the pin 51 through the upper through hole 531 and the lower through hole 521, thereby achieving the effect of pre-fixing the upper support 3 and the lower support 4. After the pin 51 passes through the upper through hole 531 and the lower through hole 521, pass the cotter pin 512 through the pin hole 511 to prevent the pin 51 from easily falling out of the upper through hole 531 and the lower through hole 521.

[0036] Reference Figures 1 to 5 The second component 6 includes several locking bolts 61 and several locking nuts 62. Several upper threaded holes 63 are formed through the upper support 3, and several lower threaded holes 64 are formed through the lower support 4, with the upper threaded holes 63 and lower threaded holes 64 positioned opposite each other. The locking bolts 61 pass through the upper threaded holes 63 and lower threaded holes 64, and are threadedly connected to the locking nuts 62. The end of the locking bolt 61 abuts against the side of the upper support 3 away from the lower support 4, and the locking nut 62 abuts against the side of the lower support 4 away from the upper support 3 with a flat washer 65, which is fitted onto the locking bolt 61. To lock the upper support 3 and lower support 4, the locking bolt 61 is passed through the upper threaded holes 63 and lower threaded holes 64, and then the locking nuts 62 are tightened onto the locking bolt 61. The end of the locking bolt 61 abuts against the side of the upper support 3 away from the lower support 4, and the flat washer 65 abuts between the lower support 4 and the locking nut 62, thus achieving the locking effect between the upper support 3 and the lower support 4. The flat washer 65 distributes the pressure of the locking nut 62 on the surface of the lower support 4, reducing the possibility of damage to the surface of the lower support 4.

[0037] Reference Figures 1 to 7A first bracket 1 has several first sliding grooves 11 extending through it, and a first slider 12 is slidably disposed within each of the first sliding grooves 11. A first locking assembly 8 is installed between the first slider 12 and the first bracket 1, and the first locking assembly 8 is used to fix the first slider 12. The first locking assembly 8 includes a first screw 81 and a set of first nuts 82. The first screw 81 is installed in the first sliding groove 11, and the first screw 81 extends through the first slider 12, with the first slider 12 slidably connected to the first screw 81. The first nuts 82 are threaded onto the first screw 81, and their opposite surfaces abut against the end wall of the first slider 12. A second slider 22 is rotatably disposed on the first slider 12, and a second sliding groove 21 extends through it on the second bracket 2, with the second slider 22 slidably disposed within the second sliding groove 21. A second locking assembly 9 is installed on the second bracket 2, and the second locking assembly 9 is used to fix the second slider 22. The second locking assembly 9 includes a second screw 91 and several second nuts 92. The second screw 91 is installed in the second slide groove 21, and the second screw 91 passes through the second slider 22, which is slidably connected to the second screw 91. The second nut 92 is threadedly connected to the second screw 91, and the opposite surface of the second nut 92 abuts against the end wall of the second slider 22. When adjusting the concentricity of the spray pipe and the upper roller, the first slider 12 is first moved along the first slide groove 11 to a suitable position, and then the first nut 82 is rotated so that the opposite surface of the first nut 82 abuts against the end wall of the first slider 12, thereby fixing the first slider 12 and making the spray pipe concentric with the upper roller, achieving the effect of equidistant distance between each nozzle on the spray pipe and the upper roller. When adjusting the distance between the spray pipe and the upper roller, the second bracket 2 and the second slider 22 are first moved relative to each other, and then the second nut 92 is rotated so that the opposite surface of the second nut 92 abuts against the end wall of the second slider 22, fixing the second slider 22 in the second slide groove 21, thereby adjusting the distance between the spray pipe and the upper roller.

[0038] The implementation principle of the clamping device for the spray water pipe of the upper roll of a short-stress rolling mill according to an embodiment of this application is as follows: When the first support 1 is installed on the crossbeam, the upper support 3 is placed above the crossbeam and the lower support 4 is placed below the crossbeam, so that the crossbeam is inserted into the oppositely arranged upper through groove 31 and lower through groove 41. Then, the lower protrusion 52 is inserted between the upper protrusion 53, and then the pin 51 is passed through the upper through hole 531 and the lower through hole 521, thereby achieving the effect of pre-fixing the upper support 3 and the lower support 4. After the pin 51 passes through the upper through hole 531 and the lower through hole 521, the cotter pin 512 is passed through the pin hole 511, so that the pin 51 is not easy to fall out of the upper through hole 531 and the lower through hole 521. After the upper support 3 and the lower support 4 are pre-fixed, the upper support 3 and the lower support 4 move synchronously along the crossbeam, driving the first support 1 to slide to a suitable position, so that the central arc of the spray water pipe is aligned with the central circle of the upper roll that needs to be cooled. Finally, the upper support 3 and the lower support 4 are locked together by locking bolts 61 and locking nuts 62, clamping the crossbeam between them. When adjusting the concentricity of the spray pipe and the upper roller, first move the first slider 12 along the first slide groove 11 to a suitable position, then rotate the first nut 82 so that the opposite surface of the first nut 82 abuts against the end wall of the first slider 12, thus fixing the first slider 12 and making the spray pipe concentric with the upper roller, achieving the effect of equidistant spray nozzles on the spray pipe from the upper roller. When adjusting the distance between the spray pipe and the upper roller, first move the second bracket 2 and the second slider 22 relative to each other, then rotate the second nut 92 so that the opposite surface of the second nut 92 abuts against the end wall of the second slider 22, fixing the second slider 22 in the second slide groove 21, thus adjusting the distance between the spray pipe and the upper roller. Because the upper support 3 and lower support 4 enclose the crossbeam, the crossbeam and the first bracket 1 form a large-area surface contact and pressing structure through the upper support 3 and lower support 4. The clamping force of the second component 6 is distributed across the contact area between the upper support 3 and lower support 4 and the crossbeam, replacing the point contact pressing structure between the crossbeam and the first bracket 1. This reduces the concentration of the connection strength between the crossbeam and the first bracket 1 in a localized area, lowering the risk of loosening of the connection between the first bracket 1 and the crossbeam, and reducing the possibility of decreased positioning accuracy of the sprinkler pipe.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
