In the past 30 years, the machine tool technology has been developed greatly in the world. The development of CNC machine tool technology has shown a variety of characteristics. The main trends of high-end CNC V-bevel cutting machine are high precision, high speed, multi-axis, high reliability, multi-functional composite, reconfigurable, low energy consumption, environmental protection and intelligence.   1. The global market development and changes With the development of industrial production and the continuous progress of technology, the low-end routers in the sheet metal industry can no longer meet the demand. The middle and high-end CNC router will occupy the mainstream of market demand. German machinery has always been the leading country in the global industry. In the past, countries would import advanced  high-end CNC machine  tools from Germany. However, we should not ignore the growing mid-range technology sector. Today, more and more emerging industrial countr...

  For these smaller threads, they are typically rolled on flat die machines. These flat die machines are of conventional design and have little to no calibration adjustment. In addition, the matching process must be done by a skilled operator, and because they are continuous cycle machines, the operator must place the part in the machine at the correct point in time to successfully roll the threads. To solve these problems, some manufacturers have tried rolling small bolts on cylindrical two-die machines, which are easier to set up because the dies, once matched, remain matched throughout the rolling cycle. With constant matching and single-cycle capability, operators can roll good threads without special timing points to bring the blank into the rolling position. The two cylindrical die configuration eliminates matching and blank introduction problems and allows the use of larger dies, but neither of these two-die machines has a vertical rolling axis, making it easier to feed when...

The shortage of aerospace quality fasteners is causing production delays for new aircraft programs and highlighting the need for new and better production processes.   The shortage of aerospace-quality fasteners led to production delays for the new aircraft program and highlighted the need for new and better production processes. As a result, we applied our expertise to determine how to improve the way threads roll on them. For thread diameters of 3/8" and larger, rolling is typically done in rolling machines with three cylindrical dies. These machines have been the preferred choice for cylindrical die rolling because they use a fixed vertical rolling axis and the dies are driven uniformly to roll the centerline, eliminating the need for work support inserts. In addition, the vertical rolling axis provides a stable blank loading position. However, the maximum die diameter that can be used in a three-cylinder die configuration without die collision is only about five times the diam...

Hydraulic Plate rolls are most advance version which used in current industries because of Its features,technology and versatality of different shape making by plate bending. Where as Mechanical   rolling machines   are typically less advance but Economical solution for the small fabricator and Startup fabrication industry. Both machines are manufactured as per Different requirement of maximum plate thickness to be bent and width of that plate. Commonly 2000 mm , 2500 mm, 3000 mm width are available in the Steel plates in the market. Hydraulic Rolling machines are capable to bend more higher thickness easily compare to mechanical motorized machines. Mechanical machines are majorly used in site work, mobile fabrication plants or pipe line projects or refinery projects for maintainence purpose. Hydraulic plate rolling machine is easy to operate with less manual effort which results good productivity with minimum waste of plate ends.   Our Plate Rolling M...

3 Rolling machine rolling process Obtain material The material must be confirmed in accordance with the drawings and process requirements, and the surface of the material should not have obvious defects. Material quality and specifications should comply with relevant national standards and industry standards.   Delineate the boundary When expanding, the barrel diameter must be the same as the actual diameter of the end shell, and the barrel material diameter should be calculated according to the middle diameter of the barrel. The direction of the unfolded length should be the same as that of the rolled steel, and the limit position is 45°. The alignment should be reasonable, making full use of the edge material and improving the utilization rate of steel. When welding multiple sections of the cylinder, the welding seam should be properly configured according to the technical requirements of the equipment assembly welding. End shell butt welds, cylindrical shell section longitudinal...

Rolling machine , also called rounding machine and roller machine, is a general forming equipment for rolling metal plates into cylindrical, conical and curved shapes. According to the principle of three-point forming circle, the relative position change and rotational movement of working rollers make the metal sheet produce continuous plastic deformation, so as to obtain the workpiece of predetermined shape. It is widely used in boiler, shipbuilding, petroleum, chemical, metal structure and machinery manufacturing industries. As shown in the figure below, the three-roller plate rolling machine usually takes two lower rollers as the active rollers, which can realize forward and reverse rotation. One upper roller is the driven roller, which can move up and down vertically.   When rolling the sheet metal, the plate is placed between the upper and lower rollers, and the plate can be bent into an arc or closed circle through the three cutting points exposed on the sheet metal by the th...
