Technical Field

[0001] This utility model relates to the technical field of two-roll cold rolling mills, specifically a two-roll cold rolling mill with a limiting mechanism. Background Technology

[0002] Two-roll cold rolling mills are cold rolling equipment consisting of two rolls. They are mainly used for the plastic deformation processing of metal materials and are also known as two-roll mills. They are divided into two types: reversible and irreversible. Reversible mills include primary rolling mills, rail beam rolling mills, and medium and heavy plate rolling mills, while irreversible mills include billet continuous rolling mills, lap-rolled thin plate rolling mills, etc. The maximum roll diameter is 1500 mm, the roll length is 3500 mm, and the rolling speed is 3 to 7 m / s.

[0003] However, when the two-roll cold rolling mill is in operation, in order to align the center of the raw material with the center of the upper and lower pressure rollers, it is often necessary to replace the pads of different thicknesses at the feed port, which is cumbersome and time-consuming. Therefore, it does not meet the existing requirements. In response, we have proposed a two-roll cold rolling mill with a limiting mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a two-roll cold rolling mill with a limiting mechanism to solve the problem mentioned in the background art that when the two-roll cold rolling mill is working, it is often necessary to replace the pads of different thicknesses at the material outlet in order to align the center of the raw material with the center of the upper and lower pressure rollers, which is cumbersome and time-consuming.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1 to 4 As shown, a two-roll cold rolling mill with a limiting mechanism includes an equipment housing 1. An operation panel 2 is fixed to the side of the equipment housing 1. A maintenance cover 4 is also installed on the side of the equipment housing 1. Both the front and rear faces of the equipment housing 1 are provided with material inlets 3. The material inlets 3 on the front face of the equipment housing 1 are provided with receiving grooves 5 at both the top and bottom. An adjustable electric telescopic rod 6 is fixed inside the receiving groove 5. The two adjustable electric telescopic rods 6 are symmetrically positioned vertically. A limiting support plate 7 is fixed to the movable end of the adjustable electric telescopic rod 6. Limiting guide plates 8 are slidably installed at both ends of the limiting support plate 7. Multiple guide rods 10 are rotatably installed at the bottom of the limiting support plate 7. The guide rods 10 are linearly arrayed along the width direction of the limiting support plate 7. The height of the limiting support plate 7 is adjusted by adjusting the electric telescopic rods 6, so that the two limiting support plates 7 clamp and limit the raw material sheet entering the material inlet 3.

[0016] One end of the limiting guide plate 8 is slidably inserted into the limiting support plate 7 and the end is bent in an L shape. A threaded sleeve 15 is fixedly embedded in this end of the limiting guide plate 8. An adjusting motor 12 is fixed inside the limiting support plate 7. A venting groove is opened at the bottom of the limiting support plate 7. The venting groove is located above and below the adjusting motor 12, and the length of the venting groove is less than the length of the adjusting motor 12. This is used to dissipate heat from the adjusting motor 12 during operation, so as to prevent the adjusting motor 12 from malfunctioning or being damaged due to untimely heat dissipation.

[0017] An adjusting gear 13 is fixed to the output shaft end of the adjusting motor 12. A lead screw gear 14 is meshed on one side of the adjusting gear 13. A double-ended lead screw 11 is fixed through the axis of the lead screw gear 14. The end of the double-ended lead screw 11 passes through a threaded sleeve 15 and is driven by the threaded sleeve 15. The double-ended lead screw 11 is rotatably connected to the limiting support plate 7 through roller bearings. The two threaded sleeves 15 are moved relative to each other or towards each other by adjusting the motor 12 and the double-ended lead screw 11, thereby adjusting the position of the limiting guide plate 8.

[0018] The end of the limiting guide plate 8 located outside the limiting support plate 7 is bent downwards, and the inner surface of the bent end is inlaid with contact balls 9. The bent end of the limiting guide plate 8 located outside the limiting support plate 7 is arc-shaped, and this end of the limiting guide plate 8 outputs downwards. The contact balls 9 at the end of the limiting guide plate 8 contact the side of the raw material plate to laterally limit the conveying raw material plate.

[0019] Working principle: When rolling raw material sheets using a two-roll cold rolling mill, the thickness of the raw material sheet is first input into the control terminal of the two-roll cold rolling mill. Then, the control terminal calculates the distance that the two limit support plates 7 need to be adjusted based on the thickness of the raw material sheet and the distance between the upper and lower pressure rollers of the two-roll cold rolling mill. After the adjustment distance is calculated, the electric telescopic rod 6 is energized and drives the limit support plates 7 to move until the limit support plates 7 have moved the distance calculated by the control terminal. At this time, the distance between the upper and lower adjacent guide rods 10 is the thickness of the raw material sheet. The raw material sheet is fed between the two limit support plates 7. At the same time, the motor 12 is energized and started, and drives the double-headed lead screw 11 to rotate through the adjusting gear 13 and the lead screw gear 14. This causes the double-headed lead screw 11 to drive the limit guide plate 8 to retract into the limit support plate 7 through the threaded sleeve 15 until the outer ends of the two limit guide plates 8 are in contact with the side of the raw material sheet, thus completing the lateral limit of the raw material sheet. No manual replacement of the pads is required, shortening the operation time.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
