Description

Technical Field

[0001] The utility model relates to the technical field of color steel plate production equipment, in particular to a width-adjustable cold roll forming machine with good finished plate rolling effect. Background Art

[0002] The cold roll forming machine is one of the important equipment in the color steel composite plate production line. It is used to roll the color steel composite plate panels.

[0003] Existing width-adjustable roll forming machines use rollers mounted on cantilevered roller shafts to roll the steel plates on both sides. A bracket supports the center of the steel plate during rolling. During operation, the cantilevered roller shaft rotates, driving the rollers, which in turn continuously convey the steel plate forward. One side wall panel (mostly the left wall panel) is adjustable, allowing it to be moved left and right via the machine frame rails to accommodate steel plates of varying widths. In practice, these roll forming machines present the following challenges: 1) After the cantilevered roller shaft is installed, the shaft is loaded, causing the shaft head to tilt downward. This can lead to roller jitter during rolling, resulting in uneven final dimensions and uneven depth of the finished plate. 2) As the rollers roll the steel plates, lateral forces are generated from both sides, squeezing the steel plates inward. Because the bracket supports the steel plates from below, this can cause the center of the steel plate to arch upward, resulting in an uneven and defective surface.

[0004] Therefore, it is of great practical significance to develop a width-adjustable cold roll forming machine with good finished plate rolling effect. Utility Model Content

[0005] Since the prior art has the above-mentioned defects, the utility model provides a width-adjustable cold roll forming machine with good finished plate rolling effect, so as to solve the problem that the existing width-adjustable cold roll forming machine has poor finished plate rolling effect.

[0009] The width-adjustable cold roll forming machine of the utility model has a reasonable structural design. The design of upper and lower through-axles plus a lower pressure roller can avoid the phenomenon of arching in the middle of the steel plate; the cantilever roller shaft design is eliminated, the through-axle design has good roller operation stability, the finished plate rolling effect is good, and the application prospect is good.

A bracket 4 is also installed between the left wall panel 5 and the right wall panel 6. During operation, the roller 2 is mounted on the cantilever roller shaft 1 to roll both sides of the steel plate 3. The bracket 4 supports the middle part of the steel plate 3.

[0028] A width-adjustable cold roll forming machine comprises a drive motor, a left wall panel 5 and a right wall panel 6 arranged opposite to each other;

[0029] The working surface is provided with a frame guide rail 7 arranged along the direction from the left wall panel 5 to the right wall panel 6. The left wall panel 5 is slidably connected to the frame guide rail 7. An upper through shaft 8 and a lower through shaft 9 arranged up and down are provided between the left wall panel 5 and the right wall panel 6.

A left roller is installed on the lower sliding sleeve 13, and a right roller is installed on the other end of the lower through shaft 9. The left roller and the right roller are respectively provided. The rollers are respectively installed on both sides of the lower through shaft 9. One end of the lower through shaft 9 passes through the right wall panel 6 and is fitted with a transmission part I. The drive shaft of the drive motor is fitted with a transmission part II. The transmission chain is fitted on the transmission part I and the transmission part II. The middle parts of the upper through shaft 8 and the lower through shaft 9 are respectively provided with upper pressure rollers 10 and lower pressure rollers 11 that match each other (there are multiple groups of upper pressure rollers 10 and lower pressure rollers 11, and the multiple groups of upper pressure rollers 10 and lower pressure rollers 11 are respectively arranged on the upper through shaft 8 and the lower through shaft 9, and the positions and specifications of the upper pressure rollers 10 and lower pressure rollers 11 match).
