Translational rolling mechanism

Abstract

The invention relates to a translational rolling mechanism. The translational rolling mechanism comprises a rack, a rolling shaft and a contact compression roller; a rolling shaft support is arranged on a horizontal rail in a mode of being capable of moving back and forth, and is provided with an oil cylinder capable of pushing the rolling shaft support to move back and forth; a contact compression roller support is arranged on the rack in a mode of being capable of moving back and forth, and is provided with an air cylinder which applies pushing force on the contact compression roller support, and the piston rod of the air cylinder is connected with the contact compression roller support; and the translational rolling mechanism also comprises a central control processor, a sensing air cylinder piston rod or a linear displacement sensor for the displacement of the contact compression roller support, wherein the linear displacement sensor is connected to the central control processor, the central control processor is connected with the drive circuit of the oil cylinder, and the central control processor controls the oil cylinder to operate according to the signal of the linear displacement sensor. The invention ensures that the pressure between a finished scroll and the contact compression roller is stable; the transmission path and clipped corner for a rolled material to entering into a finished roll remain unchanged all the time; and the rolling quality is ensured, thus the translational rolling mechanism is suitable for high-grade rolled material rolling, large-diameter rolled material rolling and high-speed rolling.

Description

technical field [0001] The invention belongs to a mechanism for winding coiled materials, in particular to a translational rolling mechanism. Background technique [0002] With the development of coiled products, people have higher and higher requirements for the quality of coiling. On the other hand, more and more coils hope to realize the large-diameter, high-speed, and large-width winding process, but the larger the diameter of the coil, the higher the speed, and the larger the width, the more difficult the winding quality control. [0003] In the prior art, there are the following four types of winding mechanisms for center winding: [0004] The first type of winding mechanism such as figure 1 As shown, the characteristics of this mechanism are that the positions of the guide roller 12 and the winding shaft 2 are fixed during the winding process, and the center distance of the coil 11 from the guide roller 12 to the winding shaft 2 remains unchanged; the first mechani...

[0004] The first type of winding mechanism such as figure 1 As shown, the characteristics of this mechanism are that the positions of the guide roller 12 and the winding shaft 2 are fixed during the winding process, and the center distance of the coil 11 from the guide roller 12 to the winding shaft 2 remains unchanged; the first mechanism is insufficient Yes: As the diameter of the finished roll increases, the transmission path between the guide roller 12 and the tangent point of the finished roll will evolve from the initial position AC to the final position BC, that is, the distance and tangent angle of the transmission path will change, resulting in The tension distribution of the coil is very uneven, and the winding quality is difficult to guarantee

Compared with the first three winding mechanisms, the winding quality of the above fourth winding mechanism has been improved, but there are still deficiencies, for example, the pressure between the finished roll 11 and the touch roller 3 cannot be kept constant; this is because, The pressure P between the finished roll and the touch roller mainly comes from the thrust of the cylinder 4, and P=F-f, where P represents the pressure between the finished roll and the touch roller, F represents the thrust of the cylinder, and f represents the winding shaft support 21 and Friction between the horizontal rails 22; due to the continuous increase in the diameter of the finished roll and the weight of the finished roll 11 during the winding process, the friction force f between the winding shaft support and the horizontal rail is constantly changing; in addition, As mentioned above, when large-diameter winding is performed, the stroke of the piston rod of the cylinder is large, and the volume of the pressure chamber inside the cylinder also changes greatly. The pressure P between the roll and the touch roller is constantly changing, which affects the winding quality
