Description

Technical Field

[0001] This invention belongs to the field of multi-roller straightening technology for multi-specification metal sheets, and specifically relates to the design of a roller straightening machine with a replaceable integrated motor-driven roller system assembly. Background Technology

[0002] Currently, the variety and specifications of metal sheet and strip are diverse both domestically and internationally, with a trend towards extremely wide, thin, and high-strength products. Older roller straighteners typically consist of a single transmission structure with one or two roller systems. However, for straightening newer sheet materials such as high-strength products, older straighteners suffer from insufficient power and unsuitable roller systems. Adding multiple roller systems is limited by the fixed output shaft distance of the transmission mechanism, and the roller system replacement process requires cumbersome shaft alignment. Therefore, these older straighteners can only produce metal sheets within the thickness range of older equipment, and cannot produce metal sheets and strips exceeding this range. This severely restricts enterprise development, forcing companies to increase the variety of equipment to improve their product specifications and production capacity, resulting in significant resource waste and investment costs. Summary of the Invention

[0003] The purpose of this invention is to provide a roller straightener with a replaceable integrated motor-driven roller assembly, enabling the retrofitting of old straightener equipment to meet the power requirements of new specifications of metal sheets such as ultra-thin and high-strength sheets, as well as the roller diameter requirements of various specifications. The coupling position holding device maintains the coupling position when the old straightener's roller system is pulled out, allowing for quick installation of the original roller system and avoiding the cumbersome connection work of the coupling shaft. Furthermore, the integrated motor-driven roller assembly allows for precise design of the roller diameter and motor power according to the specifications of the metal sheet or strip being produced, without affecting the working capacity of the old straightener, minimizing energy consumption, and effectively solving the problem of aligning the shaft head of the working roller with the corresponding shaft sleeve when replacing the straightening roller system in old straightener equipment, thus improving the roller changing efficiency and working range of the straightener.

[0004] The implementation of this invention is shown in Figure 1. It includes: I. Roll changing mechanism (1. Roll changing motor and transmission chain, 2. Guide rail, 3. Roll system connection device); II. Integrated motor-driven roller system assembly (4. Bearing plate, 5. Guide pulley, 6. Reducer and gear distribution box, 7. New power motor, 8.

Old straightener roller system (16. Old lower roller box, 17. Old lower roller box, 18. Old lower roller box, 19 ... The invention comprises: 18 working rolls, 19 old upper working rolls; IV movable crossbeams (20 movable crossbeams); V pressing and balancing system (21 balance bar, 22 pressing hydraulic cylinder); VI prestressed frame (23 hydraulic nut, 24 column); VII connecting shaft position holding device (25 connecting shaft fixing device); VIII old straightening machine transmission mechanism (26 old universal joint shaft, 27 old gear distribution box, 28 reduction gearbox, 29 old power motor); IX roller system positioning mechanism (including 30 spring positioning pin, 31 hydraulic support cylinder). The invention is characterized by: ① By mounting the new roller system (32) and the reducer and gear distribution box (6) on the bearing plate (4) to form a whole, the new roller system (32) and the reducer and gear distribution box (6) are connected by a new cross universal joint (8) for power transmission. The new power motor (7) is located on the reducer and gear distribution box (6), forming a roller system assembly with interchangeable roller system integrated motor drive.

[0005] ② The replaceable roller system integrated with the motor drive roller assembly II can be precisely designed to meet the roller diameter and power motor requirements for producing extremely thin, high-strength metal sheets, maximizing energy utilization. It can also be completely removed without affecting the straightening performance of the old straightening machine.

[0006] ③ The connecting shaft position and posture holding device VII can be used to remove the old straightener roller system III and install the replaceable roller system integrated motor drive roller system assembly II without changing the position and posture, thereby improving the installation speed of the old straightener III.

[0007] The advantages and positive effects of this invention are that it facilitates the transformation of old roller straighteners, meets the power requirements of new specifications of metal sheets such as ultra-thin and high-strength sheets, and meets the requirements of roller diameters of various specifications. Among them, the connecting shaft position holding device can maintain the position of the coupling when the old straightener roller system is pulled out, which can quickly install the original roller system and avoid the tedious alignment work of connecting the coupling shaft. Moreover, the integrated motor-driven roller system assembly can accurately design the roller diameter and motor power according to the specifications of the metal sheet and strip to be produced, so as to minimize energy consumption. At the same time, this invention does not affect the capacity of the original equipment, improves the working capacity and roller changing speed of the straightener, saves energy, and improves production efficiency.

[0031] As shown in Figures 1 and 2, the hydraulic support cylinder 31 first lifts up, restoring the spring positioning pin to its original position. The roller system connecting device 3 in the roller changing mechanism I then detaches from the old straightener roller system III. The connecting shaft fixing device 25 in the connecting shaft position holding device VII fixes the old universal joint connecting shaft 26 in its original position. Then, the roller changing mechanism I pushes the integrated motor drive roller system assembly II into the roller straightener, realizing the replacement of the new power and the new roller system. This meets the requirements for producing new specifications of metal sheets such as ultra-thin and high-strength rollers. After use, to replace the old straightener roller system, simply pull out the integrated motor drive roller system assembly II in the roller changing mechanism I and then push the old straightener roller system III in. Due to the function of the connecting shaft position holding device VII and the connecting shaft fixing device 25, the position remains unchanged, avoiding the tedious work of connecting shaft alignment and effectively improving production efficiency.
