Description

Technical Field

[0001] The invention relates to the technical field of operation and maintenance of a rolled steel plate straightener, and in particular to a roller changing and connecting device for a straightener roller system. Background Art

[0002] On a steel rolling production line, the straightening machine is a crucial piece of equipment. With the accelerating pace of production, its usage is increasing. After a certain period of use, the straightening rollers become severely worn, necessitating replacement and repair of the roller system to ensure effective straightening of the steel plate. Each roller system replacement takes time, and the production line is shut down during the roll change. Therefore, reducing roll change time means improving productivity. Currently, roll system connection methods for roll change generally use pins. Pins are manually inserted from top to bottom into the pin holes of the roll change trolley and the roll system. Once the trolley and roll system are connected, the roll system is pulled out and pushed in. This entire process requires manual back-and-forth alignment of the pin holes before inserting the pins. This reduces roll change efficiency, takes a long time, and poses safety risks. Summary of the Invention

[0003] In view of the problem that current technology requires manual installation of roller changing connecting pins, which is time-consuming and labor-intensive, the purpose of the present invention is to provide a roller changing connecting device for a straightening machine roller system, so as to shorten the roller changing time, improve production efficiency and enhance the safety factor of the operation.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a straightening machine roller system roller changing connection device, including guide connection devices respectively installed on the roller system end and the roller changing trolley end, the guide connection devices are respectively provided with guide pins and guide holes for centering in the horizontal direction, and a semi-cylindrical mounting groove and a semi-cylindrical connecting block located in the mounting groove are respectively provided in the middle of the guide pin, and a cylinder for driving the semi-cylindrical connecting block to rotate is respectively provided on the roller system end and the roller changing trolley end, and the transverse centering guide pin is symmetrically designed, and one is provided on the roller changing trolley and one is provided on the roller system. The cylinder is controlled by an electromagnetic valve and connected to the roller changing operation screen for remote operation.

[0005] This invention provides an automatic roller connection device for straightening machine roll replacement, enabling a human-free connection process that is quick and convenient. It boasts safe and reliable operation, a high degree of automation, low labor intensity, and easy maintenance, significantly improving roll replacement efficiency. The invention is applicable to all hot straightening machine roll replacement operations, and the automated connection technology is readily applicable. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a schematic diagram of the separation state structure of the present invention; Figure 2 It is a schematic diagram of the connection state structure of the present invention. Implementation Method

[0007] A roller changing and connecting device for a straightening machine roller system, such as Figure 1 、 2 As shown, it includes guide connecting devices respectively installed on the roll system end 4 and the roll changing trolley end 7, and the guide connecting devices are respectively provided with guide pins 2 and guide holes 1 for centering in the transverse direction. A semi-cylindrical mounting groove 6 and a semi-cylindrical connecting block 5 located in the mounting groove are respectively provided in the middle of the guide pin 2. Cylinders 3 for driving the semi-cylindrical connecting block to rotate are respectively provided on the roll system end 4 and the roll changing trolley end 7. The transverse centering guide pins 2 are symmetrically designed, and one is provided on the roll changing trolley and one is provided on the roll system. The cylinders are controlled by solenoid valves and connected to the roll changing operation screen for remote operation.

[0008] The roller-changing trolley's guide pins 2 have tapered ends at one end to facilitate insertion into the guide holes 1, while the other ends are fixed to the roller-changing trolley and roller system, respectively. The guide pins 2 are mounted horizontally, eliminating the need for manual insertion of the pins. When preparing to change rollers, the air cylinder 3 is extended to rotate the semi-cylindrical connecting block 5 to a horizontal position. The roller-changing trolley is then pushed forward, inserting the guide pins on the roller-changing trolley into the guide holes on the roller system. Simultaneously, the guide pins 2 on the roller system are also inserted into the guide holes 1 on the roller-changing trolley. Once the guide pins 2 on both sides have been inserted into the guide holes, the air cylinder 3 is actuated again, rotating the semi-cylindrical connecting block 5 to a certain angle, securing it completely within the connecting block mounting slot 6.
