CZ channel machine is made by processing hot-rolled steel plates or strips into specific cross-sectional shapes through cold bending forming technology. It has the characteristics of standardized specifications and optimized cross-sections, and is widely used in steel structure engineering. Under the automatic control of the PLC system, CZ frame making machine can be made into two shapes: C-shaped and Z-shaped. The steel goes through multiple rolling processes to form efficiently and stably into C-type or Z-type. This system can not only accurately adjust the bending angle and arc, but also quickly switch production modes according to preset parameters, greatly improving production efficiency and product accuracy. Its specifications are highly standardized, with a material thickness of about 1.5-3mm and a width of about 200-600mm.
CZ purlin machine adopt a arch structure type, which can significantly enhance the stability of production equipment. The portal frame structure is built with C-shaped and Z-shaped steel, which can effectively disperse the vibration and pressure generated during equipment operation, reducing equipment shaking. Compared with non-portal frame structures, its anti-deformation ability is increased by more than 40%, ensuring the equipment remains stable during high-speed operation.Once the equipment runs stably, internal components are less likely to be misaligned. Combined with the precise control of the PLC system, this can minimize the dimensional error of steel profiles and greatly improve product accuracy.
In terms of production efficiency, the stable portal frame structure provides a basis for equipment speed-up. The average production speed of the equipment remains at about 25-40 meters per minute, which has greatly improved efficiency compared with other structures. In addition, the equipment can automatically adjust the production speed according to the thickness of the steel: when encountering thicker steel, it will automatically reduce the speed to ensure the forming quality; when encountering thinner steel, it will increase the speed to boost production capacity, meeting production needs of different scales.
In the feeding inlet ofCZ channel machine, besides using the "one-drag-one-press" method to prevent materials from jumping up and down, a leveling device is also used to flatten the materials.
In the production process of CZ frame making machine, the feeding inlet serves as the starting link for materials to enter the processing system. Its stability and material condition play a crucial role in the quality of the final product. To ensure the precise positioning and stable transportation of materials at the feeding inlet, and to prevent processing deviations and equipment failures caused by material jumping, the production process adopts a dual protect mechanism of "one-drag-one-press" collaborative control and a leveling device.
In the production process of CZ purlin machine, when materials enter the feeding inlet, to prevent them from jumping up and down, besides using the "one-drag-one-press" method for control, a special leveling device is also equipped to flatten the materials. Specifically, the "one-drag-one-press" forms two-way constraints during material transportation, effectively suppressing the vertical displacement of materials. The leveling device, by means of multiple sets of upper and lower interlaced leveling rolls, applies uniform pressure to the materials. Through repeated rolling, it eliminates uneven problems such as wavy bending and local bulges on the material surface, making the materials reach a flat state before entering subsequent processing procedures. The application of this dual measure can not only ensure the stability of material transportation but also improve the processing accuracy of materials, laying a good foundation for the subsequent forming, welding and other processes of CZ channel machine.
To prevent the material from twisting left and right when entering the feeding inlet, we specially designed edge-trimming wheels to keep the material in a flat state.
In the production process of CZ frame making machine, the stability of materials at the feeding inlet directly affects the accuracy of subsequent processes and product quality. To effectively solve problems such as material twisting and offset, we innovatively designed an edge-trimming wheel device, establishing a precise control line for material shape.
The edge-trimming wheel device is composed of edge-trimming wheels symmetrically arranged on both sides of the feeding inlet. Each edge-trimming wheel is made of high-strength alloy steel and processed by precise grinding to ensure zero damage to the material surface. According to the width and thickness of the material, the millimeter-level fine adjustment of the spacing between edge-trimming wheels can be realized through a high-precision screw adjustment mechanism, so as to accurately adapt to materials of different specifications. When the material enters the feeding inlet, the edge-trimming wheels on both sides simultaneously apply uniform and appropriate lateral pressure to the material edges. By using the principle of rolling friction, the material is firmly constrained on the preset conveying path.
Moreover, the edge-trimming wheel device also has a collaborative leveling function. The outer surface of the edge-trimming wheel is designed with a special arc profile. While restraining the position of the material, it can real-time trim minor wavy deformations, curled edges and other uneven phenomena on the material edges.
