Description

Precision adjusting device for pinch roll

Technical Field

The utility model relates to a metal plate and strip production facility technical field specifically is pinch roll precision adjustment devices.

Background

At present, in a strip steel production processing line in the metallurgical industry, pinch rolls are very important equipment and are generally used in pairs and are divided into an upper pinch roll and a lower pinch roll, the lower pinch roll is fixed like , the upper pinch roll tightly presses a roll gap between the two rolls by the thrust of an air cylinder or a hydraulic cylinder so as to drive a metal strip to be fed in a specified direction, and the position precision of the two sides of the lower pinch roll plays a key role in judging whether the metal strip deviates in the pinching process.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide types of pinch roll precision adjusting devices so as to conveniently, quickly and effectively adjust the precision of the pinch roll.

In order to achieve the purpose, the adjusting device of the utility model is arranged between the frame and the bearing seat on both sides of the lower pinch roll, the base of the adjusting device is fixed with the frame through a screw , the wear-resistant plate is connected with the bearing seat through a screw II, the screw rod which is pushed against the bottom of the wear-resistant plate is in threaded connection with the base, the middle part of the screw rod is marked with a scale mark, and the screw rod is locked on the base through a round nut after the precision of the pinch roll is adjusted.

The head of the screw is an outer hexagon, the circumference is equally divided into 100 parts by the scale mark marked in the middle, and the rest parts are external threads with the thread pitch of 2 mm; the center of the base is an internal thread with the thread pitch of 2mm, and is in threaded connection with the screw rod.

The utility model discloses the sign scale mark at screw rod middle part divides 100 with the pitch 2mm of external screw thread partition, the outer hexagonal of rotatory screw rod head, check scale marks are rotated, screw rod axial displacement 0.02mm, according to the difference in height of pinch roll both sides down, just can adjust the position accuracy of pinch roll down, then with round nut locking screw rod the roll diameter reduces after pinch roll coping down, can calculate the check number that the scale mark corresponds according to the coping of roll diameter, rotatory outer hexagonal, just can send the roll gap position between pinch roll and the lower pinch roll in the quick adjustment to and send.

Compared with the prior art, the utility model, the most obvious characteristics are the rotatory screw rod jacking bearing frame of accessible, realize adjusting the position accuracy of pinch roll both sides down, and the graduation scale mark on the screw rod makes the adjustment volume readable, controllable, accurate, compact structure, and the adjustment method is simple high-efficient.

Drawings

Fig. 1 is a schematic structure diagram of the utility model.

Fig. 2 is a schematic view of the present invention.

Fig. 3 is a partial schematic view of fig. 2.

In the figure, the rolling mill comprises an upper pinch roll 1, a lower pinch roll 2, a bearing seat 3, a screw rod 4, a round nut 5, a base 6, a screw 7, a screw , an abrasion-resistant plate 8, a screw II 10, a scale mark 11, a frame 12, an external thread 13, an internal thread 14, an external hexagon 15, a roll diameter 16 and a rolling line.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses an adjusting device arranges in between frame 11 and the bearing frame 3 of pinch roll 2 both sides down, adjusting device's base 6 is fixed with screw 7 and frame 11 and is played, and wear-resisting plate 8 is connected with bearing frame 3 with two 9 screws, and the top is at screw rod 4 and the base 6 threaded connection of wear-resisting plate 8 bottom, and the middle part of screw rod 4 marks scale mark 10, after the pinch roll precision adjustment, locks screw rod 4 on base 6 with round nut 5.

The head of the screw rod 4 is an outer hexagon 14, the circumference is equally divided into 100 parts by a scale mark 10 marked in the middle, and the rest part is an external thread 12 with the thread pitch of 2 mm; the center of the base 6 is provided with an internal thread 13 with the thread pitch of 2mm, and the internal thread is in threaded connection with the screw rod 4.

During adjustment, the outer hexagon 14 at the head of the screw rod 4 is rotated, -grid scale marks 10 are rotated, the screw rod 4 moves axially by 0.02mm, the position accuracy of the lower pinch roll 2 can be adjusted according to the height difference of two sides of the lower pinch roll 2, and then the screw rod 4 is locked by the round nut 5.

If the roll diameter 15 is reduced after the lower pinch roll 2 is ground, the lattice number corresponding to the scale mark 10 can be calculated according to the grinding amount of the roll diameter 15 of the lower pinch roll 2, and the roll gap position between the upper pinch roll 1 and the lower pinch roll 2 can be quickly adjusted to be equal to the rolling line 16 by rotating the outer hexagon 14.
