Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal pressure processing, in particular to a hole-type cooling water pipe and a guide and guard adjustment combined device. Background Art
[0002] In the hot rolling production line of metal pressure processing, in order to obtain the required product shape, a hole system of a certain shape will be engraved on the roll of the rolling mill. During the steel rolling process, the hot rolled piece contacts the groove on the roll, which increases the temperature at the groove. Since the surface metal at the groove is in direct contact with the hot rolled piece, its temperature is higher than that of the internal metal. Therefore, the expansion of the surface metal of the groove due to heat is greater than that of the internal metal, so the internal metal produces compressive stress on the surface metal; when the groove cools, the temperature of the surface metal of the groove is lower than that of the internal metal, and the contraction of the surface metal is greater than that of the internal metal, so the internal metal produces tensile stress on the surface metal. The above-mentioned repeated alternating thermal stress is the root cause of fatigue cracks in the roll. The fatigue crack is a stress concentration area, which is easy to cause roll breakage and block falling, and the groove on the roll is cast from expensive alloy materials. In order to reduce fatigue cracks caused by thermal fatigue, cooling water must be used to take away the heat obtained by the roller from the rolled piece, thereby reducing the temperature rise of the roller and the expansion of the surface metal to reduce fatigue cracks. The cooling of the annular water pipe is more accurate and concentrated, and the effect is better, but its installation is more complicated. Generally, the water pipe needs to be welded to the support above the beam when in use. When the hole type is changed, it must be gas cut and re-welded to change the position. Frequent replacement has a short service life of the water pipe, which is very easy to damage, and the installation and replacement time is long. In the prior art, there is also a method of directly installing the annular water pipe on the guide beam through a mounting frame, but this method also requires the position of the mounting frame to be adjusted separately according to the replaced roller. It is very necessary to design a time-saving and labor-saving device for online replacement. Utility Model Content

The annular water pipe 2 is connected to the water pipe joint 3, and the annular water pipe 2 is connected to the mounting frame. The crossbeam 6 is installed on the guide beam of the rolling mill, and a sliding groove 9 is provided on the crossbeam 6. The threaded sleeve 5 is slidably connected to the sliding groove 9. The pressure rod 4 passes through the threaded sleeve 5 and is threadedly connected to the threaded sleeve 5. The mounting frame is set between the upper end of the threaded sleeve 5 and the crossbeam 6. The mounting frame can slide along the threaded sleeve 5. The lower end of the threaded sleeve 5 is provided with threads, and the nut 7 presses the mounting frame between the threaded sleeve 5 and the crossbeam 6.
[0025] Example 2
[0026] This embodiment is based on embodiment 1, and its further specific scheme is:
[0027] The inner wall of the threaded sleeve 5 is provided with an internal thread, and the outer wall of the pressure rod 4 is provided with an external thread.
[0028] The rolling mill guide beam is the prior art. A crossbeam 6 is installed above the guide beam. A sliding groove 9 is provided in the middle of the crossbeam 6 along the length direction. The sliding groove 9 is a long hole. The length of the long hole is slightly smaller than the length of the crossbeam 6. The purpose is to match the position of the guide 8 as much as possible. The annular water pipe 2 is arc-shaped, and the length of the arc is 1 / 4 to 1 / 3 of the circumference of the groove of the roller pass. A plurality of nozzles are evenly distributed at the bottom of the annular water pipe 2, and the nozzles are connected to the inside of the annular water pipe 2.
[0029] like Figure 2 As shown, the top of the threaded sleeve 5 is provided with an annular protrusion, the upper outer wall of the threaded sleeve 5 is a smooth surface, the lower outer wall of the threaded sleeve 5 is provided with an external thread, the nut 7 is connected with the external thread, and the mounting frame is provided with an adjustment hole 10, the upper end of the threaded sleeve 5 passes through the adjustment hole 10 of the mounting frame and can slide along the adjustment hole 10, and the mounting frame is placed below the annular protrusion of the threaded sleeve 5. The height of the smooth surface of the upper outer wall of the threaded sleeve 5 is less than the thickness of the mounting frame plus the crossbeam 6. The adjustment hole 10 is also a long hole.
[0030] Usage process:
[0031] During installation, first place the mounting frame of the annular water pipe 2 above the crossbeam 6, with the length direction of the adjustment hole 10 of the mounting frame perpendicular to the length direction of the sliding groove 9 of the crossbeam 6, and then sequentially pass the threaded sleeve 5 through the adjustment hole 10 and the sliding groove 9, at which point the annular raised bottom surface of the threaded sleeve 5 contacts the top surface of the mounting frame, and then tighten the thread at the lower end of the threaded sleeve 5 to complete the preliminary installation. Then, according to the position of the roller pass, adjust the distance between the annular water pipe 2 and the pass, tighten the nut 7, install the guide, adjust the position of the threaded sleeve 5, further tighten the nut 7, and then adjust the pressure rod 4 to fix the guide 8.
[0032] After adjusting and replacing the roll hole profile, the position of the roll position is adjusted on the rolling mill guide beam to make the guide and the roll hole profile position correspond. Since the center line of the mounting frame of the annular water pipe 2 corresponds to the center line of the pressure rod 4, when the position of the threaded sleeve 5 is adjusted to be located on the center line of the guide 8, the annular water pipe 2 can be made to correspond to the hole profile position of the new roll. The distance between the annular water pipe 2 and the roll hole profile can be adjusted by adjusting the position of the mounting frame as needed. At this time, the nut 7 is tightened first, and then the pressure rod 4 is tightened to fix the guide. The technical solution of the utility model can simultaneously adjust the center line of the annular water pipe 2 to correspond to the center line of the new roll hole profile while adjusting the clamping device, reducing the adjustment of the single annular water pipe 2 along the length direction of the crossbeam 6. It is only necessary to adjust the distance between the annular water pipe 2 and the roll hole profile.
