Why choose double - layer color steel tile machine?

To meet in the limited area of the need of forming the two section, can quickly transform product, double mill (double caigang watts forming machine, double integration equipment) was designed and manufactured, the double caigang watts molding machine is between the high or low frame transformation, produce a kind of color steel plate installed on the lower frame of contour, producing a roll of another kind of plate installed in high above the frame, the production line has a decoiler, a cutting press, if the color plate feeding the lower roll, forming a plate type (e.g., bungalows with the beatles and pack), such as material feeding top roller, and forming another section (layers).In order to adapt to the two layers of the product, the cutting die also has two layers of height, the final product processing equipment behind the cutting die should be able to adjust up and down, to adapt to the two kinds of plate outlet height.Double layer color steel tile forming machine, the emergence of this equipment, greatly save space, the time to replace two kinds of plate also becomes shorter, also improve the production rate, but at the same time, because of the relatively crowded, it is difficult to install the auxiliary roller frame, difficult to adjust and check the molding condition.Introduction of advantages and disadvantages of cantilever binding machine (press machine)?The shaft of the cantilever binding machine is only supported on one side, so it is sometimes called the overhanging binding machine or shaft end mill.The cantilever binding machine that produces the locking edge of the plate is popular in the plate metal forming factory for a long time.Cantilever binding machine low cost, machine is not complex, less debugging, cantilever binding machine bending more and more popular.Advantages of cantilever binding machine: 1. Relatively low cost.2. It has the ability to shape the edges of any width plate. Disadvantages: 1. A single adjusting screw makes it difficult to set the required roller clearance. 2. The main material of color steel plate house and steel structure roof plate is the import press color steel equipment manufacture, the inner clip high strength foam plate or color steel press plate, has the characteristics of long life, corrosion resistance.

1.Color steel machine is mainly ordinary or light, due to the section size are relatively high, relatively narrow, so the moment of inertia of the two main sleeve section difference is large.Therefore, it can only be used directly in the plane of its web bending member or to form a lattice force member.It is not suitable for axial compression members or bending members perpendicular to web plane, so it has a great limitation in its application scope.

2, color steel is a high-efficiency and economical cutting surface profiles (other cold-formed thin-wall steel, pressed steel plate, etc.), due to the reasonable shape of the section, they can make the steel more efficient, improve the capacity of cutting.Different from the ordinary type is the h-shaped steel wing embroidery has been widened, and the inner and outer surfaces are usually parallel, so that it can be easy to use high strength screw laurel and other components.Its dimensions constitute a reasonable series, model complete, easy to design and choose.The rolling of cagl equipment is different from that of ordinary I-steel with only one set of horizontal rollers. Because of its wide width and no slope (or very small slope), it is necessary to add a set of vertical rollers for rolling at the same time.Therefore, its rolling process and equipment are more complex than ordinary rolling mill. China's national standard "Hot rolled H-beam Size, Shape, Weight and Allowable Deviation" (GB11L263-89) divides H-beam into three types of narrow flange, wide flange and steel pile, whose codes are HZ, HK and HU respectively.Narrow wings are suitable for beam or flexural members, while wide flange color steel equipment and H-shaped steel pile are suitable for axial compression members or flexural members.

Improvement of C beam machine:

Section steel equipment is a set of roll can produce a variety of specifications of c-type purlin finished single-roll forming unit.This kind of equipment mainly consists of passive loading rack, leveling device, punching device, cutting device after forming, hydraulic station, computer control system and so on. The machine adopts automatic flying saw to punch holes, easy to operate and so on. Process flow: the strip is sent from the tail of the equipment, and then pressed into C-shaped steel by various rollers and sent out from the head. In the traditional process, after the c-section steel is pressed and molded, it needs to be manually cut off at fixed length, and then transported to the punching equipment to punch holes according to the size required by the customer, so the production cannot be continuous and the efficiency is not high. Through the gradual improvement of the production process, the automatic control of the whole process was finally realized, which greatly improved the production efficiency and increased the technical content and added value of the customer's equipment. The improvement process is accomplished in three steps.The first step is improved by adding the length measuring device and the flying saw. When the pressing length reaches the set length, the flying saw will automatically cut off the profile. The second step is improved by adding a hydraulic punching equipment for punching edge holes, punching four holes at the same time, and cutting them off from the middle with flying saw, thus forming two side holes for each head and tail of two adjacent sections of C-beam steel.The third step is to add a hole punching device. In the process of strip pressing, a hole can be punched out according to the spacing set by the user, and the maximum hole can be punched 16 holes.In the fourth step, according to the requirement of the new C-section steel to punch double holes in the middle of the profile, the 4-hole punch mould of the side hole is changed to the 2-hole mould, and the program of punching the side hole is modified, so that the side hole punch equipment can punch double holes in the middle, and the hole distance is set by the user, and the maximum is 8 groups of double holes.In this way C steel machine can meet the needs of the market.The difference between C-beam and Z-beam purlins A and Z-beam purlins are better overall than C-beam purlins because the inertia distance in the weak axis direction is larger than similar C-beam purlins.B. Because of the tight lap at the joints, the lap becomes a continuous purlin, while the C type purlin can only be counted as a simple span purlin. C and Z purlins are smaller than C purlins, which can save material and reduce cost. However, installation and transportation are more complicated than C-shaped purlins. D, C steel machine is generally suitable for gentle roofing;Z-beam steel is suitable for roofing with gradient greater than 1/4.

2. Selection of C beam machine and Z beam machine 。A -general roof load is large, c-type purlin calculation is difficult or calculated results need to choose the super C-type purlin, consider using Z-type purlin.B. In areas with large basic wind pressure, the purlin is often controlled by the wind suction at this time. At this time, if c-type purlin is difficult to calculate, z-type purlin can also be selected.
