How to choose the working table length and tonnage of the pipe bending machine correctly?

In order to select the bender with the lowest tonnage specification, it is best to plan for a bending radius greater than the thickness of the material, and use the free bending method as much as possible. When the bending radius is large, it is often based on the premise of not affecting the quality of the finished part and its future use. The selection of the pipe bending machine will not only affect the bending effect of the material, but also affect the actual production cost of the equipment. Once the selection is inappropriate, it may increase the cost. Therefore, when choosing a pipe bending machine, it is necessary to consider various factors.

First of all, it is worth noting that each part of the pipe bending machine should try to choose the model with the shortest working table and the smallest tonnage under the premise of meeting the processing tasks. At the same time, it is necessary to carefully consider the material grade and the maximum processing thickness and length. If most of the work is low carbon steel with a thickness of 16 and a maximum length of 3m, the free bending force need not be greater than 50 tons. Under the same load, the probability of deflection of the 10-foot machine table and slider will be greatly increased. This means that shorter machines require fewer shim adjustments to produce qualified parts and reduce shim The film adjustment shortens the preparation time. Assuming the thickest material is 1/4 inch, a 10-foot free bend requires a 200-ton pipe bender, while a bottomed die bend requires at least 600 tons. If most of the work pieces are 5 feet or shorter, the tonnage is almost halved, which greatly reduces the purchase cost. It can be seen that the length of the parts is very important to determine the specifications of the machine.
