Description

Technical Field

[0001] The utility model belongs to the technical field of strip steel bending auxiliary equipment, in particular to a strip steel bending cooling device. Background Art

[0002] During various processing processes, strip steel may bend or twist due to external forces, temperature changes and the growth and decline of internal forces. These deformations often appear as wave bends in the vertical plane and sickle bends in the horizontal plane. Therefore, copper-plated strip steel needs to be straightened and bent before coiling, so strip steel bending equipment came into being, such as a copper-plated strip steel bending and straightening machine disclosed in the patent document with publication number CN117862273A.

[0003] Since the bending and straightening of strip steel is a deformation process, the deformed metal structure is constantly changing during the deformation process; therefore, due to the influence of the heating effect during plastic deformation, the temperature of the strip steel will rise to a certain extent to form a deformation temperature during the bending and straightening process; in order to prevent the deformation temperature from affecting the strip steel being bent through metal heat conduction, and at the same time avoid the high-temperature strip steel from being tightened due to thermal expansion and contraction after coiling, causing the steel coil to easily collapse and cause safety hazards, it is necessary to cool the strip steel after bending and straightening.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0027] A strip bending and cooling device comprises: a frame 1 and a drawing shaft 3; the frame 1 is a gantry structure, with a bearing seat 2 fixed on each side of the frame 1, and a drawing shaft 3 with a shaft structure can be plugged in and out and rotatably matched in the bearing seat 2; a floating frame 6 is arranged above the drawing shaft 3, and the main body of the floating frame 6 is two groups of long plate structures, and the two groups of long plate structures are vertically connected and fixed by two groups of roller seat plates 61 with plate-like structures, and at least one group of sliding seats 5 are respectively arranged at both ends of the side of the floating frame 6 close to the frame 1, and the sliding seats 5 are slidably matched on a vertical slide rail 4, and the slide rail 4 is fixed on the frame 1, and a floating roller 9 is rotatably matched between the two groups of roller seat plates 61 by bearings, and a plurality of nozzles 7 are directly or indirectly arranged on the floating frame 6.

[0028] In order to facilitate the removal of the strip steel coil 10 after it is formed, and to facilitate the connection of the pulling shaft 3 to the rotating power source, the length of the pulling shaft 3 is greater than the maximum width of the two bearing seats 2, so that the pulling shaft 3 protrudes to the outside of the bearing seat 2 on one side to form a power extension end 31.

[0029] In order to facilitate the adjustment of the position of the nozzle 7, the floating frame 6 is indirectly connected to the nozzle through a nozzle adjustment mechanism 8, and the nozzle adjustment mechanism 8 includes: a first pulley 81, a second pulley 82, a connecting belt 83, and a holder 84; the two groups of long plate structures of the floating frame 6 are each rotatably matched with the first pulley 81 and the second pulley 82, and the first pulley 81 and the second pulley 82 are connected by a connecting belt 83 for transmission, and the lower part of the connecting belt 83 is in a horizontal state, and a plurality of holders 84 are fixed at the horizontal part below the connecting belt 83, and the nozzle 7 is fixed on the holder 84, and the nozzle of the nozzle 7 is vertically downward.

[0030] In order to offset the spray reaction forces of the nozzles 7 when the nozzles 7 are working and prevent the nozzles 7 from being deflected due to the spray reaction forces, the holder 84 is a symmetrical structure, and the two groups of nozzles 7 on the holder 84 are symmetrically arranged on the symmetric plane of the holder 84.

[0031] In order to relatively fix the holder 84 below the connecting belt 83 , a threaded hole is provided at the center of the holder, and a fastening bolt 89 is screwed into the threaded hole. After the fastening bolt 89 is tightened, the holder 84 is fixed to the connecting belt 83 .

[0032] In order to improve the floating accuracy of the floating roller 9 , the floating roller 9 is located directly above the drawing shaft 3 .

[0033] In order to uniformly adjust the horizontal positions of all the nozzles 7, the nozzle adjustment mechanism 8 also includes: a rocker arm 87; a straight hole with a prismatic structure is provided at the center of the second pulley 82 to form a socket 86, and a prismatic rod 88 is fixed on the rocker arm 87, and the rod 88 can be inserted into the socket 86.

[0034] In order to facilitate the unified regulation of the horizontal positions of the nozzles 7 on both sides of the floating frame 6, the two groups of first pulleys 81 or the two groups of second pulleys 82 are coaxially fixed with a transmission rod 85 of a rod-shaped structure.

[0035] Brief description of the usage process:

[0036] When in use, the pull-out shaft 3 is inserted into the two sets of bearing seats 2, and a hose is used to connect all the nozzles 7 to a high-pressure airflow or a high-pressure cold airflow, such as Figure 1As shown, the strip that has just been bent is passed under the nozzle 7 and wrapped around the drawing shaft 3, and the high-pressure airflow or high-pressure cold airflow connected to the nozzle 7 on the side close to the strip feeding direction is turned on. The turned-on nozzle 7 blows air downward to perform "air cooling" on the strip passing under it, thereby cooling the bent strip.

[0037] When the drawing shaft 3 is wound with a certain amount of strip steel, a strip steel coil 10 is formed. Then, the high-pressure airflow or high-pressure cold airflow connected to the nozzle 7 on the side away from the strip steel feeding direction is turned on to perform double cooling of the strip steel. Because the outer diameter of the strip steel coil 10 gradually increases as the strip steel is wound, if the position of the nozzle 7 does not follow the change of the outer diameter of the strip steel coil 10, the gradually thickened strip steel coil 10 will block the nozzle 7, resulting in "poor air cooling effect"; so at this time, if Figure 4 As shown, the floating roller 9 and the top of the strip steel coil 10 are tangent to each other, so that as the winding diameter of the strip steel coil 10 increases, the floating roller 9 will rise along with the increasing diameter of the strip steel coil 10, and then the roller seat plate 61 that rotates with the floating roller 9 will also rise, and then the roller seat plate 61 will drive the floating frame 6, the nozzle 7, and the nozzle adjustment mechanism 8 to rise as a whole. Through the establishment of the slide rail 4 and the slide seat 5, when the floating frame 6 rises, it will only rise along the slide rail 4 through the slide seat 5, preventing the position of the floating roller 9 from shifting so that it is always located directly above the highest point of the strip steel coil 10. Based on the above principle, the spraying distance of the nozzle 7 relative to the feed strip steel is maintained at a certain distance, preventing the gradually thickening strip steel coil 10 from clogging the nozzle 7 and affecting the air cooling effect.

[0038] After cooling is completed, a transfer support mechanism for the steel strip coil 10 is set under the steel strip coil 10, and then the pulling shaft 3 is pulled out from the bearing seat 2, so that the cooled steel strip coil 10 can be transferred and stored through the transfer support mechanism, and then the pulling shaft 3 is reinserted into the bearing seat 2 to carry out the winding and cooling work of the next group of strip steel after bending.

[0039] When the winding power is insufficient, a coupling can be used to connect the power extension end 31 of the pulling shaft 3 to an external rotating power source to assist the winding operation of the strip steel coil 10 .

[0040] When the position of the nozzle 7 needs to be adjusted according to the width of the strip steel coil 10, loosen all the fastening bolts 89 on the holder 84, and then adaptably adjust the distribution and spacing of the nozzle 7 on the connecting belt 83 according to the width of the strip steel coil 10. After the adjustment, re-lock all the fastening bolts 89.

[0041] When the horizontal position of the nozzle 7 needs to be uniformly adjusted, the insertion rod 88 on the rocker arm 87 is inserted into the socket 86, and the rocker arm 87 is rotated. The rocker arm 87 drives the second pulley 82 to rotate through the insertion rod 88 and the socket 86, and the second pulley 82 drives the connecting belt 83 to rotate, and then the holder 84 and the nozzle 7 on the connecting belt 83 are driven to move uniformly. The first pulley 81 and the second pulley 82 on the other side of the floating frame 6 are synchronously rotated by the transmission rod 85, and the holder 84 and the nozzle 7 on the connecting belt 83 thereon are also driven to move uniformly.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
