What matters should be paid attention to in the introduction and operation of hydraulic bending machine

Hydraulic bending machine includes bracket, worktable and clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate. The base is connected with the clamping plate by hinges. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When used, the coil is connected by the wire
  In the bending process of the bending machine, there is no pressure between the upper die and the lower die. The required bending angle is obtained by adjusting the depth of the die opening.   This bending method is called bending clearance. Deep into the lower die die, the bending angle of the bender is small, the larger, and vice versa. Because of elastic materials, the advantage of bending clearance is that when bending controls springback and over bending, you can use fewer moulds to achieve a variety of angles, processing and less pressure. Normally, in order to obtain the best bending effect, the ratio of material thickness T to V-shaped opening width of V-shaped lower die is based on T:1:8V:
  The following points should be paid attention to in the operation of hydraulic bender:
  1. In this process, the pressure weakness automatically stops falling, while the pressure or the process of a large increase slows down, and can not fall or rise.
  2. Automatic stop when pressure; increase is normal, not rapid decline, but the normal pressure of the product.
  3. When high and low pressure products. Sometimes it's half normal, sometimes it's half abnormal. But when the relationship is normal, the two sides are abnormal. The normal and abnormal middle of the two sides.
