Problems solved by technology

[0004] At present, there are different degrees of warpage in densely porous panels stamped and formed by using thin metal plates in any way, especially the warping of the edge straight plates that have not been pressed, because the positioning and installation of these straight plate parts will cause seams during use. It is not strict, which affects the use effect; and the existence of blind hole bosses makes it impossible to use the plate rolling machine to press, which limits the application of dense blind hole plates

Embodiment Construction

[0020] The invention provides an arc rolling device for a dense blind hole plate, such as figure 1 As shown, it is composed of three rollers, which are driving roller 1, driven pressing wheel 4 and guiding pressing wheel 6 respectively. Below the dynamic compression wheel 4, three rollers are arranged in the shape of "product"; the three rollers are respectively equipped with a blind hole plate limiter 7, and the extrusion surface of the driven compression wheel 4 is groove-shaped, and the two The end extrusion surface is higher than the extrusion surface of the middle section, and the height difference is the protruding height of the blind hole. Among the groove-shaped extrusion surfaces of the driven pinch wheel 4, the extrusion surface of the concave part is a rubber surface. like figure 2 As shown, the driving roller 1 , the driven pressing wheel 4 and the guiding pressing wheel 6 are respectively connected to the support wall 10 through the supporting shaft 9 of the pr...

Abstract

The invention provides an arcuation device for a dense blind hole plate, which is composed of three rollers, i.e. a driving roller, a driven pinch roller and a guiding pinch roller, and is characterized in that the driving roller and the guiding pinch roller are parallel to each other and are arranged below the driven pinch roller; the three rollers are arranged in a delta shape and provided with dense blind hole plate limiting platforms; an extrusion surface of the driven pinch roller is in a groove shape; the extrusion surfaces at the two ends of the roller are higher than the extrusion surfaces at the middle section of the roller; and the height difference is the protruding height of a dense blind hole. The arcuation device can achieve stretching and trimming of a dense blind hole part and a metal straight plate part simultaneously in the rolling process, and a warped edge straight plate part is pressed to be flat to obtain the circular arc meeting requirements and ensuring installation of a flat installation surface. The arcuation device is simple in structure, easy and simple in operation and suitable for popularization, and the finish product quality is high.

Description

[0001] technical field [0002] The invention discloses an arc curling device, in particular for trimming the deformed portion of a blind hole boss pressed by a dense blind hole plate, and pressing the warped edge straight plate smoothly, belonging to the field of mechanical processing. [0003] Background technique [0004] At present, there are different degrees of warpage in densely porous panels stamped and formed by using thin metal plates in any way, especially the warping of the edge straight plates that have not been pressed, because the positioning and installation of these straight plate parts will cause seams during use. It is not strict, which affects the use effect; and the existence of blind hole bosses makes it impossible to use the plate rolling machine to press, which limits the application of dense blind hole plates. [0005] Contents of the invention [0006] In order to solve the above-mentioned problems in the prior art, the present invention provide...
