Abstract
Description
Technical Field
[0001] The utility model relates to the field of bar processing equipment, in particular to a bar guide fine-tuning device. Background Art
[0002] The guide of the short stress rolling mill for bars is installed on the guide beam of the rolling mill. Its main function is to be installed before and after the roll pass to help the rolled piece enter and exit the roll pass accurately and stably in the predetermined direction and state during the rolling process of the bars. Before the short stress rolling mill is put into operation, the guide device and the roll pass are aligned by adjusting the threaded screw at the bottom of the guide beam. This method requires manual visual observation and centering adjustment. After the rolling mill is put into operation, the traditional adjustment method is still to adjust the guide beam screw, but visual observation is difficult at this time, the centering accuracy of the guide device cannot be guaranteed, and the stability of subsequent rolling passes is affected; especially in the bar slitting rolling, it is often necessary to adjust the pre-slitting pass guide alignment during rolling to directly control the shape of each wire after slitting. If the guide adjustment accuracy is poor, the quality of the finished product cannot be guaranteed, and the production failure rate increases.
[0003] To this end, we propose a guide fine-tuning device for short stress rolling mills to solve the above problems. Utility Model Content

[0006] Furthermore, one side of the guide box 6 abuts against the base 1 , and the other side of the guide box 6 abuts against the pressure plate 5 .
[0007] Furthermore, the fixing bolt 2 is provided with a locking nut 4 for fixing and locking, and an anti-skid washer 3 for preventing the locking nut 4 from loosening and sliding.
[0008] Furthermore, the half nut 8 is fixedly connected to the base 1 , and the half nut 8 and the adjusting screw 7 are meshed with each other.
[0009] Furthermore, both left and right ends of the adjusting screw 7 are provided with hexagonal adjusting knobs 7 - 1 .
[0010] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: on the basis of the rough adjustment of the threaded screw at the bottom of the guide beam before the rolling mill is put into operation, the guide fine-tuning device realizes further precise fine-tuning after the rolling mill is put into operation, which better ensures the stability of rolling and has a good effect on improving the quality of the finished products of the rolled parts.

[0016] See also Figure 1-Figure 3 As shown, the technical solution adopted in this specific embodiment is: it includes a base 1, a fine-tuning device cavity A is opened on the base 1, a pressure plate 5 is provided on one side of the inner cavity of the fine-tuning device cavity A, and the pressure plate 5 is bolted to the base 1 through a fixing bolt 2, and a guide box 6 is provided on the other side of the inner cavity of the fine-tuning device cavity A, an adjusting screw 7 is provided on the base 1 below the guide box 6, and a half nut 8 is provided between the adjusting screw 7 and the base 1.
[0017] More specifically, one side of the guide box 6 abuts against the base 1, and the other side of the guide box 6 abuts against the pressing plate 5. The pressing plate 5 and the base 1 prevent and fix the guide box 6 to prevent the guide box 6 from falling and loosening.
[0018] To be more specific, the fixing bolt 2 is provided with a locking nut 4 for fixing and locking, and an anti-skid washer 3 for preventing the locking nut 4 from loosening and sliding.
[0019] More specifically, the half nut 8 is fixedly connected to the base 1, and the half nut 8 is meshed with the adjusting screw 7. By arranging the half nut 8 on the base 1, the meshing effect of the half nut 8 and the adjusting screw 7 is utilized so that the adjusting screw 7 can adjust the position of the guide box 6.
[0020] More specifically, both left and right ends of the adjusting screw 7 are provided with hexagonal adjusting knobs 7-1, which are convenient for the staff to rotate and adjust the adjusting screw 7.
[0021] More specifically, a key is provided at the bottom of the base 1 to facilitate the connection between the base 1 and the rolling mill guide beam.
[0022] The working principle of the utility model is as follows: before the rolling mill is put into operation, the guide and guard fine-tuning device is installed on the guide and guard beam of the rolling mill, and is positioned with the guide and guard beam of the rolling mill by a key-keyway, and is locked and fixed by a locking buckle plate. The guide and guard box 6 is installed in the cavity A of the fine-tuning device, positioned by the keyway in the cavity A of the fine-tuning device, and is locked by the top thread. First, the guide and guard box 6 is roughly adjusted to the centering degree by the threaded screw at the bottom of the guide and guard beam, and the adjustment is assisted by manual visual observation. After the rolling mill is put into operation, the rolling worker determines the difference of each wire groove and the adjustment direction of the guide and guard by observing and measuring the process parameters such as the wire material type and the loop height after cutting. In combination with the results of various process parameters, the adjusting screw 7 is adjusted to achieve precise fine-tuning of the guide and guard centering degree, and then the pressure plate 5 is used to cooperate with the fixing bolt 2 for locking and fixing.
[0023] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
