Steel plate flattening device

Abstract

The invention provides a steel plate flattening device which comprises a base, a frame body, and a preliminary pressing roll device, a guide roll device, a roller device and a forming roll device that are sequentially arranged along the length direction of the base, wherein the preliminary pressing roll device comprises a lower preliminary pressing roll and a height-adjustable upper preliminary pressing roll correspondingly arranged above the lower preliminary pressing roll; the guide roll device comprises two height-adjustable guide rolls that are correspondingly arranged; and the distance between the two guide rolls can be adjusted; the roller device comprises an adjusting mechanism, a lower roller group fixedly mounted at the frame body, and an upper roller group above the lower roller group; the adjusting mechanism is arranged at the upper end of the frame body; the upper roller group is fixedly mounted on the adjusting mechanism; and the forming roll device comprises a lower forming roll and a height-adjustable upper forming roll correspondingly arranged above the lower forming roll. After an iron sheet is flattened twice, the flatness before processing is reached completely; and the iron sheet is limited by the guide rolls in a flattening process, so that no deviation occurs. After the flattening, preliminary forming processing is carried out by the upper forming roll and the lower forming roll, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of flattening devices, in particular to a flattening device for steel plates. Background technique [0002] In the manufacturing process of bicycles, it is often necessary to purchase iron sheet raw materials and then process them. Generally, iron sheet raw materials are rolled, so after unwinding, due to long-term winding, the unrolled iron sheet itself has The radian cannot be flattened naturally. In this way, it is difficult to control the shape during processing or slicing, which can easily lead to uneven length, which will affect the subsequent process. Therefore, it is necessary to flatten the iron sheet after unwinding to ensure slicing. accurate. Contents of the invention [0003] The problem to be solved by the present invention is to provide a flattening device for steel sheets, which can conveniently and efficiently flatten iron sheets, and can also perform primary forming processing. [0004] In order ...
