Problems solved by technology

The traditional rolling device does not consider the straightness of the flange. If the straightness of the flange of the product is not good in the actual production process, it is usually repaired by experience. This method can improve the method to a certain extent. The straightness of the flange edge cannot directly and effectively control and adjust the straightness of the flange edge of the product
Moreover, the existing method increases the production cost, and also brings certain difficulties to on-site debugging, increases the equipment debugging time, and affects the production efficiency

Embodiment Construction

[0017] see figure 1 , the device of the present invention is located at the last pass of the rolling line of the product piece. While the rollers are rolling the product piece for the last time, the flange edge straightness adjustment mechanism provided will adjust the flange edges on both sides of the product piece. Carry out shaping. The device includes rollers 11 and two roller brackets 1 supporting the rollers, and also includes two sets of flanges that are respectively installed on the front and rear sides of the roller bracket 1 (the feed side and the discharge side of the product) through the mounting plate 3 Edge straightness adjustment mechanism. Two sets of flange straightness adjustment mechanisms respectively trim and shape the flanges on both sides of the product to ensure that the flanges on both sides of the roll-formed product meet the straightness requirements.

[0018] see figure 1 , figure 2 and image 3 , each set of flange straightness adjustment mec...

Abstract

The invention discloses a rolling device capable of ensuring straightness of flanged edges of a cold-rolled formed product. The rolling device comprises two sets of flanged edge straightness regulating mechanisms which are separately mounted at the front side and the rear side of a roller wheel bracket, wherein each flanged edge straightness regulating mechanism comprises a regulating frame, lead screws, slide blocks and trimming roller wheels, the four lead screws are mounted on the regulating frame in parallel, each lead screw is in screw-thread fit to the corresponding slide block, each slide block is fixedly connected with a roller wheel mounting plate, each roller wheel mounting plate is assembled with one trimming roller wheel, the four trimming roller wheels comprise two vertical-axis trimming roller wheels and two inclination-axis trimming roller wheels, which are arranged in a staggered mode in a charge and discharge direction of the product. With the adoption of the rolling device disclosed by the invention, flange edge trimming of the product can be completed on the basis of not increasing product forming passes, and each trimming roller wheel is independently regulated to realize effective control on the straightness of the flanged edges at the two sides of the product, so that straightness requirements of the flanged edges of the product are met.

Description

technical field [0001] The invention relates to a forming processing equipment, in particular to a rolling device capable of ensuring the straightness of flange edges of cold-formed products. Background technique [0002] Cold roll forming is a plastic processing process in which metal sheets such as coils and strips are plastically deformed in a cold state through multi-pass forming rolls arranged in sequence to make specific cross-section profiles. Various thin-walled, reasonable-shaped and complex-section profiles can be produced by cold-rolled forming technology. Cold-formed profiles are usually carried out on rolling mills. There are a wide variety of products produced by cold forming. Many product parts used in automobiles are processed by cold forming, such as open bumpers for automobiles, door sill parts and similar door sill parts. Many of the above-mentioned products have flanges, and the forming state of the flanges directly affects the appearance of the product...
