What are the key points to pay attention to during the installation of pipe bending machine components?

The pipe bending machine industry has provided increasing technical support for the manufacturing industry. According to statistics, pipe bending machines are distributed according to the sales direction of the manufacturing sector, with sheet metal accounting for 35%, automobiles accounting for 34%, aviation industry accounting for 12%, and others accounting for 19%. Good quality pipe bending machine molds can also attract users. For users, high-quality and affordable products have always been the goal of buyers, and good products can improve the work efficiency of enterprises, which means saving processing costs and improving economic benefits. So what are the key points to pay attention to when installing the components of the pipe bending machine? The pipe bending machine manufacturer tells you:

1、 Spring back control of the pipe bending machine - the spring back is very strong when the core rod is not used. This should be considered when selecting the bending mold. Depending on the bending radius, rebound can cause the pipe to recover by 2 to 10 degrees, and may also increase the bending radius of the pipe. The smaller the bending radius, the smaller the rebound. The influence of the position and pressure of the rebound compression mold. This method produces different radii for the same bending die. Moreover, the position of the core rod can cause significant rebound, reducing the bending angle and possibly increasing the radius. When the radius increases, the core rod should be pushed forward (towards the tangent point). There is no ready-made formula for adjusting the settings of the core rod. Obviously, when the rebound angle is greater than 3 degrees, the core rod is too far back and the bending radius of the pipe will be greater than the bending die.

2、 The core rod of the bending machine is too far forward - there are several consequences of the core rod being too far forward. There will be a protrusion at the end of the tangent point on the outer side of the bend, and a depression at the beginning of the tangent point on the inner side of the bend. These deformations are exemplified on a pipe. However, due to differences in the shape and bending radius of the core rod, it does not always occur simultaneously. Feel free to use plug-in core rods, and the length of the clamping mold should be at least 3 times the diameter of the pipe.

3、 The core rod of the bending machine is too far back - the core rod is slightly forward, and there are no wrinkles at the front, but it begins to develop at the back of the cutting point. The position of the core rod is still not sufficiently forward to generate the necessary pressure on the inside and shrink the material. When the bent pipe is removed from the bending machine mold, there will be a large crease. So it is necessary to push the core rod further until the material is not squeezed between the core rod and the bending die.

4、 Picking up pump, also known as rising pump or returning pump, is usually due to the inability of the steel ball of the oil outlet valve to reset normally. The acting rod can be extended to make the plunger pump under pressure. When there is pressure on the handle seat, a few taps with a hammer can reset the valve ball.

5、 The insufficient oil suction of the large and small pumps is caused by the presence of garbage or insufficient oil on the filter mesh inside the filter. Unscrew the bent pipe mold parts, clean the mesh with gasoline, and top up with oil.

6、 The top of the top rod leaks oil, mainly due to damage to the sealing ring at the top of the piston rod, which can be replaced by 14 × 2.4 O-ring, this should be sufficient.

7、 The crack in the installation hole of the mold is usually caused by lateral load when the mold is released, such as the position of the bent workpiece not being aligned when it is bent again. It is possible to check whether the positions of the two support wheels are symmetrical, apply oil to the joint between the support wheel and the workpiece, and align the position of the second bending.
