Embodiment Construction

[0019] figure 1 The profile shown includes a dovetail groove located at the lower part. Due to the difficulty of bending, the dovetail groove generally needs to be completed first in the cold bending forming process of the profile, and then other parts are bent.

[0020] figure 2 It shows the profile after dovetail groove processing, and divides the section of the profile into 12 entities, among which entities 3, 4, 7, and 8 are arcs of bending points, and entities 1, 2, 5, 6, 9, 10, 11, and 12 are On the plane, the top of the tank is composed of entities 1 and 2, entities 5 and 6 are the walls of the tank, entities 9 and 11 and entities 10 and 12 are the two sides of the tank, and are located on the same plane. The thickness of the profile is 1.5mm, and the distance between the top and side of the groove is the depth of the dovetail groove is 4.5mm. The profile contains two symmetrical 70° dovetail angles, namely the angle between entities 1 and 5, the angle between entitie...

Abstract

The invention discloses a method for cold-bending dovetail groove in fireproofing accurate steel materials or other metal materials, the materials comprise right angle grooves of which the steel strip longitudinal roller is bent to be in cap shape, and the top part and the lateral part of the groove is bent backwards to arc shape until the bend angle achieves the requirements of the dovetail angle according to the product requirement, the arc part of the top part and the lateral part of the groove is pressed and planished ; the invention also discloses the equipment suitable for the method, as the bent section of the steel plate is located at the radial face of the roller, therefore, the bent point can be exerted with sufficient forming pressure with ease, the arc of the bent point is small, the equipment is simplified, and the production is stable and the forming speed is fast.

Description

technical field [0001] The invention belongs to the technical field of profile roll forming, and in particular relates to a roll forming method and equipment for precision cold-formed dovetail grooves of fireproof steel profiles. Background technique [0002] Roll forming refers to the use of multiple pairs of rolls with a specific profile at room temperature to make the metal plate move in a straight line in the longitudinal direction while continuously bending it laterally until it is processed into a profile with a specific cross-sectional shape required by the user, without A sheet metal deep processing process that changes its thickness. [0003] figure 2 Shown is a cross-sectional view of a fire-resistant precision cold-formed steel profile with a dovetail groove at the bottom produced by roll forming technology. The profile contains a dovetail groove with a dovetail angle of less than 90°. The dovetail groove in the profile can be used not only as a slot for multi-p...
