Classification and composition of hydraulic bending machine
The bending machine is divided into manual bending machine, hydraulic bending machine, CNC bending machine. By synchronous mode, the hydraulic bending machine can be divided into: torsion axis synchronization, machine liquid synchronization, and electro-hydraulic synchronization. According to movement pattern, hydraulic bending machine can be divided into: upper acting and under-acting. It is constituted by the bracket, table and the clamping plate, the table is placed on the stent, the table is made by the base and the platen, the base is connected by a hinge and the clamping plate; the base is composed by the seat shell, the coil and the cover plate; the coil is placed in the seat shell depression, depression at the top is covered with a lid.
Carefully consider before paying for the bending machine
The wire is energized by the coil, which generates gravity to the platen after being energized, in order to achieve the clamping of the sheet between the platen and the base. As a result of using the electromagnetic force holding, the platen can be made into a variety of workpieces requirements, which can also process the workpiece with side wall.
can meet the needs of a variety of workpieces by replacing the bending machine dies! The operation is also very simple. Prior to the payment, it is best for the prospective buyers to start carefully considering what to buy from the end use of the machine, the known scratch variable the machine may occur, and the parts bending radius aspects.
Consider the parts that you want to produce
The first important matter worthy of consideration is the parts that you want to produce; the point is to buy a machine which can complete processing tasks, has the shortest bench and minimum tonnage. Carefully consider the material grades, the largest processing thickness and length. If most of the work thickness is 16 gauge, the maximum length of low carbon steel is 10 feet, and then the free bending force does not have to be more than 50 tons. However, if engaged in a lot of the bottomed die forming, you should probably consider a 150-tonnage hydraulic press brake.
Material grade is important
Material grade is also a key factor. Compared with low carbon steel, stainless steel load requirement generally increases to about 50%, while most grades of soft aluminum reduces about 50%. At any time, you can get the machine tonnage table from the bending machine manufacturer, the table shows the tonnage per foot length in different thickness estimates and different materials.
Carefully consider bending accuracy requirements
Bending accuracy requirements are factors that need to be carefully considered, and it is this factor decides whether you need to consider a CNC bending machine or manual bending machine. If the accuracy requirement is ± 1 ° bend and cannot be changed, you must focus on the CNC machine. CNC bending machine slider repeat accuracy is ± 0.0004 inches, you must use the accuracy and good mold to form a precise angle. Manual bending machine slider repeat accuracy is ± 0.002 inches, and it will generally produce a deviation of ± 2 to 3 ° under suitable mold conditions. In addition, CNC bending machine prepares for rapid mold loading; when you need to bend a lot of small quantities of parts, this is an unquestionable consider reason.
