subject: Know The Use Of Hydraulic Shear And Profile Roll In The Mechanical Workshop [print this page] Different types of shearing machine are present in the market. And, they have different contribution in separate shearing work. By the means of shearing, any metal plate can be removed at a high level of pressure.
Most common types of shearing machines are:
Punching machines
Blanking machines
Punching machines are used to make small discs. Whereas, blanking machines are used to produce small metal items like, washers. Also, we can find out many distinctions between direct tool machines and shear machines. In case of direct tool machine, it comes with a single or multiple tools, which can remove cuttings from the block or metal sheet. When we want any specific dimension, this kind of tool is used on the metal until it can give out certain result.
Shear machine helps any cutting edge of the tool, so that it can discard the metal from the plate. Next, with the application of extreme pressure, tool cuts the metal from the plate. And then, the metal plate is squeezed only once by this tool.
Further, we can see the presence of two more categories of shear machine and they are:
Hydraulic shear
Mechanical shear
When we are expecting quick cutting, accurate and scoring of metal sheets, then hydraulic shear is found to be the one. This kind of shear is more efficient for factories, where high volumes of metal fabrication take place. Hydraulic shears are more appropriate for those workshops where there is a need for serious intense pressure. When we use these shears in the workshop, we get the benefits like, low maintenance and quick, quiet and continual usage. These shearing machines occupy less space than mechanical shear machines. But, both of them produce the same amount of pressure.
In this discussion, we will also give brief details about roll forming process, which is helpful to shape and fabricate metallic parts and profiles. The main objective of this roll forming technique is to change a metal strip or straight simple profile blanks into any desired shape. And, the entire process is done with the help of roller die assemblies.
Almost all kinds of profile shapes are required in mechanical construction activities. Different types of profile roll machines are used for bending profiles, tubes, or shapes into coils, circles or large arcs, with the use of variety of materials. Companies specializing in profile roll machines are also adopting CNC controlled machines these days due to the advancement of technologies.
