How to improve the service life of the cable?
1. Low-level repeated construction In recent years, the wire and cable industry has paid insufficient attention to the adjustment of product structure, and the contradiction of product structure is still outstanding. High-level products can not meet the needs. For example, from a broad perspective, China's bare wire production accounts for nearly one-fifth, and developed countries only account for one-tenth. In bare wires, overhead wires and ordinary steel-cored aluminum strands account for the vast majority.
2. The economic benefits are low. There are more than 700 loss-making enterprises in the whole industry, and the loss is up to 1/4. The sales income and tax rate of the industry was 11.7% in 1991 and decreased to 5% in 1995. As the benefits have been declining year after year, the number of loss-making enterprises has increased, the funds in the industry are generally tight, and the asset-liability ratio is as high as 70%.
3. The scale has grown too fast. The overall capacity of the wire and cable industry is more than double that of demand. The predicted demand for all major products in 2000 is less than the production capacity.
During the use process, the local bending radius of the shearer cable is much smaller than the bending radius of the cable specified by the standard. The cable is frequently subjected to the combination of two kinds of stresses such as excessive bending and stretching, and the control core conductor is far away. It is much smaller than the conductor cross section of the main core of the cable, resulting in the core of the control core.
1. Increase the softness of the coal mining machine cable;
2. Increase the relative slip of the control core;
3. Increase the strength of the cable conductor of the coal mining machine;
4. The conductor is changed from the original bundled structure to the regular stranding, so that its bending property can be increased, and then the steel wire is woven outside the conductor to increase its strength;
5. The control core can be mixed with tinned copper wire and steel wire, which is also a good method.
CNC Rebar Bending Machine, GF20CNC, GF25CNC Automatic Rebar Stirrup Bending Machine belongs to this type of machine.
This model control by foot pedal, and worker press the two foot pedal with 90 degree / 135 degree to control the bending angle.
1. Convenient use: perfect safety performance, standard angle, fast speed, light and
handy.
2. Easy Operation: one man can operate it once switch on the power.
3. Convenient of range adjustment: for GF20 model, just need to shift induced magnet.
for GF20 CNC and GF25CNC model, just need to press the button on operation panel
4. We adopt two foot pedals: 90°and 135°, angle adjustment freely.
5. Fast Speed: rotate speed is 20-25 times/min (GF20), 25-30 times/min(GF25).
