Embodiment Construction

[0012] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0013] The profile bending processing method of the present embodiment is as follows: figure 1 , figure 2 , image 3 , Figure 4 As shown, taking the profile material 6005A-T4 as an example, the profile section is trapezoidal, which is an irregular profile, and it is difficult to roll and bend. The specific implementation includes the following steps: first, process the shape of the trapezoidal inner cavity of the profile 2 according to the needs, and then make a trapezoidal plug 4 that matches the inner cavity of the profile 2, so that the plug 4 can just be inserted into the profile 2; secondly, the trapezoidal plug 4 4. Fix one end of the screw 6, stuff it into the profile 2, place it at the arc starting poin...

Abstract

The invention relates to a processing method for section bar roll bending. Forming devices required by the processing method include a stretch bender and a packing block. The forming method comprises the following steps that firstly, the packing block of which the shape is consistent with that of an inner cavity is manufactured according to the shape of the inner cavity of a workpiece to be processed, the packing block is fixed on one end of a screw rod, and the other end of the screw rod is fixed on a right arm of the stretch bender; secondly, the packing block is packed into the inner cavity of the workpiece and is put in the arcing position of the workpiece, and the workpiece is fixed below a top block; finally, a rotating shaft is rotated anticlockwise, so that a left arm of the stretch bender is rotated anticlockwise to drive the workpiece to perform roll bending deformation on a roll bending die, so that the workpiece to be processed is bent and formed, and the packing block is in the bending position all the time. Compared with the prior art, the processing method has the following characteristics that workpieces with different cavities can be processed, the workpieces can be uniformly stressed, and the processed workpieces have high precision in respects of section incision, workpiece depression, twisting, wrinkling and the like.

Description

technical field [0001] The invention relates to the technical field of profile processing, in particular to a profile rolling and bending processing method. Background technique [0002] At present, bending forming technology is one of the important processing methods in the manufacturing sectors of aerospace, automobile, chemical industry, shipbuilding and other fields, and occupies a very important position in the machinery manufacturing industry. Among them, stretch bending and roll bending are the two main process methods of bending forming technology. Roll bending is a process method of bending plates or profiles through rotating rollers. In the past, roll bending machines were used to achieve the shape of profiles. Roll forming. Compared with rolling bending, stretch bending is less effective in terms of workpiece force uniformity, workpiece cross-section incision, workpiece depression, twisting, etc. However, during rolling processing, the workpiece is easy to wrinkl...
