Problems solved by technology
[0005] This type of C-shaped and Z-shaped steel forming machine adopts a fixed template structure. When the mold needs to be changed, it can only be realized by replacing the wheel set. The mold changing procedure is cumbersome. It usually takes 10 to 12 hours for each mold change, and a large number of spare wheel sets are required. At the same time, frequent replacement and disassembly will affect the life and accuracy of the machine
[0006] like image 3 As shown, due to the interference of side A of the above-mentioned C-shaped steel forming machine, there is a distance K between the fulcrum P of the cold-formed forming force and the forming point M, and the bending distance K·Py is likely to occur during the forming process of the shaped steel, which affects the forming quality
In addition, in the production of C and Z-shaped steel, the thickness of the steel strip will be different according to the different specifications and raw material stiffness. The above-mentioned section steel forming machine can only meet the adjustment in the Y direction, so there is a loss of gap difference between the X and Y directions caused by the change of the thickness of the steel strip. , resulting in a change in force

Embodiment Construction
[0025] Such as Figure 4 Shown, the C-Z section steel forming machine of the present invention comprises frame 16, the carriage 17 that is placed on frame 16, this carriage 17 is provided with A road, B road, H road molding section (not shown in the figure), Respectively form the A side, B side, and H side of the section steel; a plurality of first forming combinations composed of the upper wheel 1, the forming wheel 2, and the power wheel 3 are symmetrically installed on the carriage 17 through the wheel frame group 15 left and right. In the forming section of A channel and B channel, and the attached electrical control system. The C-Z shaped steel forming machine of the present invention adopts a completely different design principle from the existing C and Z shaped steel forming machines, and changes sliding friction forming into rolling friction forming. The forming wheel 2 and the power wheel 3 are separately arranged in a split structure, an angle is formed between the ...

A C- or Z-shaped steel shaping machine is composed of machine frame, carriage plate, multiple the first shaping units consisting of upper wheel, shaping rollers and power wheel and symmetrically installed in the shaping segments of channels A and B on carriage plate, and multiple the second shaping units consisting of cantilever wheel, shaping wheel and power wheel and alternatively installed in the shaping segment of channel H on carriage plate.
Description
technical field [0001] The invention relates to a roll-type cold bending machine, in particular to a section steel forming machine suitable for producing C-shaped and Z-shaped steel purlins. Background technique [0002] C-type and Z-type cold-formed thin-walled steel purlins are suitable for carrying light roofs, such as profiled steel plates, various heat-insulating sandwich panels, asbestos roof panels and other lightweight material roofs, and flat or corrugated steel wall panels. figure 1 , 2 Shown are the cross-sectional views of C and Z-shaped steel, including sides H, B and A respectively. The production process of the product is that the steel strip (raw material) is cold-bent formed by several forming rolls. The product forming is a process of variable cross-section, which leads to the process of forming a steel strip with online variable cross-section and gradually rolling. While changing its arrangement, the amount of rolling is proportional to the internal stre...
