Description

Cut deal steekle mill coiler furnace pinch roll apparatus

Technical field

The utility model relates to the associated components of the cut deal steekle mill coiler furnace in the metallurgy industry, cut deal steekle mill coiler furnace pinch roll apparatus specifically.

Background technology

Cut deal steekle mill coiler furnace pinch roll is arranged in the outside of coiler furnace, but nestle up the coiler furnace drum device, its effect is to pierce in the process of coiler furnace rotary drum groove at hot steel band hot steel band head to be pinched in the rotary drum groove, and make to reach between pinch roll and rotary drum between milling train and pinch roll and set up certain force of strain, in addition, in rolling process, nip rolls plays the effect of a guiding.So Driven by Hydraulic Cylinder is all adopted in moving up and down of cut deal steekle mill coiler furnace pinch roll.Existing cut deal steekle mill coiler furnace pinch roll apparatus structure as shown in Figure 1, bottom pinch roll 2 is fastened on the framework 1 by bolt, top pinch roll 3 is fastened in the swing arm 4 by bolt, hydraulic cylinder 5 one ends link to each other with swing arm 4 by pin, the other end is fixed on the framework by the hydraulic cylinder gudgeon, swing arm 4 and framework 1 link to each other by pin, when last bottom pinch roll roll gap will strengthen, hydraulic cylinder 5 rodless cavity oil-feeds, top pinch roll 3 turns clockwise around pin together with swing arm 4, thereby realize that roll gap increases, same, when last bottom pinch roll roll gap will reduce, hydraulic cylinder 5 rod chamber oil-feeds, top pinch roll 3 is rotated counterclockwise around pin together with swing arm 4, thereby it is little to realize that roll gap increases, and the size of roll gap detects by the displacement transducer that is contained in hydraulic cylinder 5 rodless cavity back.There is following shortcoming in existing this cut deal steekle mill coiler furnace pinch roll apparatus: 1. displacement transducer is installed on hydraulic cylinder 5 rodless cavities, and the hydraulic cylinder rodless cavity is placed down, because of the hot rolling line inclement condition, there are many iron scales to be deposited in hydraulic cylinder gudgeon installation place, and hydraulic cylinder will be swung, thereby make displacement transducer often damage, around adding hydraulic cylinder miscellaneous equipment is arranged, the space is narrow and small, each change bit displacement sensor all will get off hydraulic cylinder changing and just can carry out, greatly influence nonscheduled down time, reduced equipment operation rate; 2. during hydraulic cylinder changing, must be the disassembling bolts at hydraulic cylinder gudgeon place, must remove the flange bolt at hydraulic cylinder oil-in place, but owing to miscellaneous equipment is arranged (as roller-way around the hydraulic cylinder, coiler furnace upright of frame and flipper guide), the space is narrow and small, and is quite unfavorable to maintenance, not only waste time and energy, and repair quality also can not get guaranteeing.This shows that existing cut deal steekle mill coiler furnace pinch roll apparatus haves much room for improvement.

Summary of the invention

Technical problem to be solved in the utility model is: the shortcoming at above prior art exists proposes a kind of consumption that reduces the hydraulic cylinder displacement transducer, overhaul of the equipments and the more rational cut deal steekle mill coiler furnace pinch roll apparatus of maintenance.

The technical scheme that the utility model solves above technical problem is:

Cut deal steekle mill coiler furnace pinch roll apparatus, comprise framework, bottom pinch roll, top pinch roll, swing arm, hydraulic cylinder and coiler furnace cruciform bracing, hydraulic cylinder one end is a rodless cavity, the other end is a rod chamber, hydraulic cylinder is provided with displacement transducer, the rodless cavity of hydraulic cylinder is connected with the coiler furnace cruciform bracing, and the rod chamber of hydraulic cylinder is connected with swing arm, and displacement transducer is located at the hydraulic cylinder top.

The rodless cavity end of hydraulic cylinder is connected with the coiler furnace cruciform bracing by hydraulic cylinder gudgeon, gudgeon gland and securing member, and the rod chamber end of hydraulic cylinder links to each other with swing arm by pin and securing member.

The utility model has the advantages that: displacement transducer is located at the hydraulic cylinder top, make the operating mode of hydraulic cylinder displacement transducer be greatly improved, can reduce the spare parts consumption amount of sensor, when changing the hydraulic cylinder displacement transducer, needn't disassemble hydraulic cylinder can carry out, can save the time of handling failure.The rodless cavity of hydraulic cylinder is connected with the coiler furnace cruciform bracing, and the rod chamber of hydraulic cylinder is connected with swing arm, makes the comparatively open up place of position of hydraulic cylinder, and the maintenance of equipment and maintenance time can reduce greatly, and repair quality also can be guaranteed simultaneously.

Description of drawings

Fig. 1 is existing cut deal steekle mill coiler furnace pinch roll apparatus structural representation.

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Embodiment one

The structure of present embodiment as shown in Figure 2, a kind of cut deal steekle mill coiler furnace pinch roll apparatus, comprise framework 1, bottom pinch roll 2, top pinch roll 3, swing arm 4, hydraulic cylinder 5 and coiler furnace cruciform bracing 6, bottom pinch roll 2 is fastened on the framework 1 by bolt, on pinch 3 rollers and be fastened in the swing arm 4 by bolt, have the coiler furnace cruciform bracing 6 of hole in the middle of hydraulic cylinder 5 passes, hydraulic cylinder 5 can be swung in this hole.The hydraulic cylinder gudgeon of the rodless cavity end of hydraulic cylinder 5 is fixed on the coiler furnace cruciform bracing 6 by gudgeon gland and securing member, and the rod chamber of hydraulic cylinder 5 links to each other with swing arm 4 by pin, and swing arm 4 and framework 1 link to each other by pin.When last bottom pinch roll roll gap will strengthen, hydraulic cylinder 5 rod chamber oil-feeds, top pinch roll 3 turns clockwise around pin together with swing arm 4, thereby realizes that roll gap increases.Equally, when last bottom pinch roll roll gap will reduce, hydraulic cylinder 5 rodless cavity oil-feeds, top pinch roll 3 is rotated counterclockwise around pin together with swing arm 4, thereby it is little to realize that roll gap increases, and the size of roll gap detects by the displacement transducer that is contained in hydraulic cylinder 5 rodless cavity back.

When the utility model is not implemented at tool, because hydraulic cylinder 5 is installed on the coiler furnace cruciform bracing 6, its rodless cavity up, the operating mode of hydraulic cylinder 5 displacement transducers is greatly improved, and can reduce the spare parts consumption amount of sensor, when changing hydraulic cylinder position 5 displacement sensors, needn't disassemble hydraulic cylinder 5 can carry out, can save the time of handling failure, hydraulic cylinder 5 be arranged in comparatively open place, top, the maintenance of equipment and maintenance time can reduce greatly, and repair quality also can be guaranteed simultaneously.

The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
