AI Technical Summary

Problems solved by technology

[0002] Most of the existing plate cutting is carried out by CNC punching machine and roller shearing machine, but the size of CNC punching machine is relatively large, and it is difficult to move it once it is installed
At the same time, the precision of the mold in the CNC punching machine is high. When there is a problem with the punching edge, it is necessary to disassemble and repair the CNC punching machine, which is not only troublesome but also time-consuming.
[0003] The current rolling shears use two cylindrical rollers with equal diameters up and down. The hobs are fixed on the rollers. Through the relative rotation of the two rollers, the hobs on the rollers cut the plate, and the two rollers When the wheel rotates relative to each other for a long time, it will generate a certain centrifugal force, which will cause burrs, flashes, plastic deformation, etc.
At the same time, when the hob is shearing, the position of each cut is the same, and long-term shearing will leave a shear gap on the roller, which will increase the gap between the hob blades, resulting in Plastic deformation occurs, so that the steel strip is not easy to cut

Example Embodiment

[0028] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0029] figure 1 , figure 2 , image 3 with Figure 4 Shows a new type of rolling shear provided by the present invention, including an eccentric roller 3 and a roller 4 arranged up and down, the eccentric roller 3 and the roller 4 are installed on the mounting frame 2, and the mounting frame 2 is installed on the base 1 The eccentric roller 3 and the roller 4 are arranged to rotate towards each other; the eccentric roller 3 is provided with a notch 31, and the blade 12 is fixedly installed at the notch 31. The relative rotation of the eccentric roller 3 and the roller 4 can guide the plate Moving forward, and when the blade 12 and the roller 4 on the eccentric roller 3 rotate to the cutting position, the blade 12 directly cuts the steel strip, and the device cuts the plate with a thickness of 10 mm or more.

Abstract

The invention discloses a novel slitting roller and relates to a shearing device. The slitting roller comprises an eccentric roller and a roller wheel, wherein the eccentric roller and the roller wheel are arranged up and down and rotate oppositely; the eccentric roller is provided with a gap, and a blade is fixedly mounted at the gap. According to the novel slitting roller, shearing inertia of the eccentric roller can be effectively utilized to improve the shearing effect and passing ability of plates; meanwhile, in the plate shearing process, shearing of the plates is assisted by the eccentric roller and self-gravity, so that the shearing effect is better, and the service life of the roller wheel is prolonged; besides, the novel slitting roller is small in size and convenient to move and install.
