The characteristic of angle sawing machine is rotary table, the fixture is fixed and the saw bow can rotate. This is good for time and material, but due to the rotation of the saw bow, the guide head moves away from the workpiece, and the span of the guide head of the saw bow increases, which causes vibration during cutting and affects the cutting accuracy. The larger the angle is, the farther the guide is not from the clamp. As the saw bow is close to the fixture when the saw bow rotates to the required angle, the large processing capacity is reduced. The cost is low, but the operator needs to rotate the workpiece manually. If the cutting workpiece is very long, the worktable also needs to move at the same time, which will increase more auxiliary time.

In the use of ordinary Angle sawing machine Because of the falling of the saw bow, the cutting will change continuously under the action of gravity, while the angle sawing machine will not encounter the above problems due to the design. Its constant feed force and linear cutting make the feed force lasting and the service life of the saw blade longer.

In addition to CNC sawing machine, all the workpieces need to be measured manually. Measuring on the angle sawing machine is more convenient than that on the ordinary sawing machine. The ordinary saw machine needs more time to stick the saw blade to the workpiece when measuring from the sawing machine. The fixture fixed on the angle sawing machine is the rear fixture, which is closer to the saw blade and convenient for measurement than the ordinary saw blade. The power of the sawing machine adopts high and low speed motors, which can meet the requirements of various materials and cross-section sawing.

Because the angle sawing machine is a little special, so I want to talk about the performance of angle sawing machine here.

1. The angle sawing machine has the function of rotating 0 ° to 45 ° and the whole machine can complete the oblique cutting of any angle between 0 ° and 45 ° when the workpiece does not move and the whole machine rotates. When the angle value is reached in the process of table rotation, the rotation is stopped. At this time, the braking device is used to brake to ensure the angle accuracy. The agreed rotation mode is driven by hydraulic motor and reducer, and the angle position is determined by the reading of magnetic ruler magnetic head, and the angle error is not more than ± 0.2 °. The hydraulic cylinder is used to lock the rotation positioning, and two positioning points are clamped.

2. Reasonable guide device of saw band can effectively prolong the service life of saw band. The guide device of movable saw blade and side pressing device move together, which has stable structure and flexible movement. The transmission parts are precisely balanced and corrected to reduce vibration. The unique hydraulic system design has a stable falling speed. During the sawing process, the saw belt will automatically lift a certain distance, and then cut again. This precision system can prevent abnormal damage of the saw blade and achieve the ideal sawing effect.

3. The band saw blade is tensioned by hydraulic pressure. The saw blade also maintains good tension force during rapid movement, which extends the service life of the saw blade. The user can adjust the pressure according to the size of the section steel. In addition, there is a detection device for the fracture of the saw blade. If the saw band breaks, the sawing machine will automatically shut down.

4. When sawing H-beam, the sequence of the inclined saw blade contacting the workpiece is as follows: one side wing plate → two side wing plate → web plate → two side wing plate → one side wing plate. It can automatically lift and re cut, and feed back through rotary encoder.

5. The main drive adopts high-power gear reducer with strong power and reliable performance. After precise balance correction, it runs stably and reliably. 6. In order to prevent the workpiece from tilting when pressing, the gantry of the main engine is equipped with an upper pressure cylinder to ensure that the workpiece is compacted with the lower datum plane when pressing the workpiece.

6. High efficiency and energy-saving PLC is used to design simple circuit to realize the automation of feeding, clamping and sawing process. The excellent space of electric box not only ensures the low failure rate of the machine, but also facilitates the maintenance and saves time.
