In the invention, the first stop block 14 and the second stop block 15 are required to be installed on site of a user, and the positioning welding is firm after the positions are adjusted.
According to the technical characteristics of the report, the use method is further described by combining the actual operation working conditions:
after the rolling is carried out for a period of time in practice, the guide rule pushing plate rotates due to uneven wear degree of the stress surface, or after the guide rule pushing plate clamps rolled pieces, the roller way is operated by mistake, and the stress condition is as follows:
1. when (1) forward rolling, the push plate 4 of the front guide rule 1 (the rear guide rule 2) of the rolling mill clamps the rolled piece 3, but the roller way rotates due to misoperation, so that the rolled piece 3 tends to move forwards (from left to right), and the push plate 4 clamps the rolled piece 3 to work in a load mode.
(2) The push plate 4 of the front guide rule 1 (the rear guide rule 2) of the rolling mill has uneven wear degree of the stress surface, so that the opening degree size: inlet side > outlet side.
In the two working states, the acting force F of the push plate 4 on the rolled piece 3 is perpendicular to the rolled piece 3 and is obliquely directed to the center line of the roller way; correspondingly, the reaction force F 'of the rolled piece 3 to the push plate 4 is perpendicular to the rolled piece 3 and obliquely deviates from the center line of the roller way, so that a component force Fr' along the horizontal direction is generated.
Due to the existence of the horizontal component force Fr', the T-head foundation bolts 10 distributed on the guide base 8 generate a rotation trend. Along the moving direction (from left to right) of the rolled piece and the right side of the inlet direction, T-shaped head foundation bolts 10 distributed on the guide rule base 8 are in right-handed rotation; the left side of the inlet direction, T-shaped head foundation bolts 10 distributed on the guide rule base 8 are left-handed.
2. When (1) back rolling, the push plate 4 of the rear guide rule 2 (the front guide rule 1) of the rolling mill clamps the rolled piece 3, but the roller way rotates due to misoperation, so that the rolled piece 3 tends to move backwards (from right to left), and the push plate 4 clamps the rolled piece 3 to work in a load mode.
(2) The push plate 4 of the rear guide 2 (front guide 1) of the rolling mill has uneven wear degree of the stress surface, so that the opening degree size: the outlet side > the inlet side.
In the two working states, the acting force F of the push plate 4 on the rolled piece 3 is perpendicular to the rolled piece 3 and is obliquely directed to the center line of the roller way; correspondingly, the reaction force F' of the rolled piece 3 to the push plate 4 is perpendicular to the rolled piece 3 and obliquely deviates from the center line of the roller way, so as to generate a component force F along the horizontal direction L ′。
Due to the levelComponent force F L The presence of' causes a tendency for the T-head anchor bolts 10 distributed on the guide base 8 to rotate. T-shaped head anchor bolts 10 distributed on the guide base 8 are left-handed along the moving direction (from right to left) of the rolled piece and the left side of the outlet direction; on the right side of the outlet direction, T-shaped head foundation bolts 10 distributed on the guide rule base 8 are in right rotation.
When the push plate 4 is worn or the roller way is rotated by misoperation, a horizontal component force Fr' (or F) is generated during clamping the rolled piece L ') the T-shaped head foundation bolt 10 generates a rotation trend and has poor shock resistance, thereby causing the nut to rotate loose and the guide base 8 to be unstable.
Aiming at the working states, an impact-resistant guide base 8 is designed to solve the practical problems, and the technical characteristics are as follows:
according to the stress analysis of the T-shaped head foundation bolt 10, the rotation trend of the T-shaped head foundation bolt 10 in an abnormal working state is mastered, the single rotation direction arrangement mode of the original T-shaped head foundation bolt 10 is broken, the threads of the T-shaped head foundation bolt 10 are arranged in a left rotation mode and a right rotation mode, and the T-shaped head foundation bolt is arranged at intervals along the guide base 8.
According to the arrangement form, even if the stress surface of the push plate 4 is worn or the roller way rotates due to misoperation and other extreme conditions occur, 50% of T-shaped head foundation bolts 10 always work normally to fix the guide base 8, so that the technical problems of loosening of nut rotation, instability of the guide base 8 and the like under abnormal conditions can be effectively solved, and the shock resistance of the guide base is improved.
3. The guide base is convenient to install, is designed into an integral type, and is cast by concrete for the foundation bolt to enhance stability, but later disassembly difficulty is high, the concrete needs to be chiseled destructively, and maintenance and inspection time is long.
Aiming at the problems of high difficulty in disassembling foundation bolts, long maintenance and inspection time consumption and the like, the guide rule base 8 capable of being replaced quickly is designed and has the technical characteristics that:
the box body 9 and the guide base 8 are designed into separate types, so that the box body is convenient to hoist; the T-shaped head foundation bolts 10 are adopted between the box body 9 and the guide base 8, so that destructive dismantling of a concrete structure is avoided, dismounting time is saved conveniently, and maintenance and inspection efficiency is improved.
