How to distinguish quality during the operation safety of pipe bending machines at different stages
The fully automatic pipe bending machine is a multi-step programming function that can also achieve automatic operation, which can greatly help improve production efficiency. Because the hydraulic pipe bending machine adopts a steel plate welding structure, it can eliminate stress during vibration.
1： Downward motion, the ordinary downward fast closing motion generally adopts the free fall type, which generates motion through its own weight; However, the production of the mold is not like this, but uses a hydraulic cylinder rodless chamber to generate pressure, which allows the fast feed pipe bending machine to reach a speed of 250mm/s, making it more suitable for the production of stronger molds.
?? The fast forward motion starts from the top dead center and ends with a brief brake at the end, such as bending the sheet for a distance. The specific adjustment can be made according to different mold manufacturing requirements.
2： In a stationary state, the fully automatic pipe bending machine is in a stationary position with the upper bending beam at the top dead center. This state is to prevent uncontrolled downward movement and reduce safety risks.
3： Decompression, which involves reducing pressure in the rodless chamber of the pipe bending machine or starting after the holding time when the bottom dead center is reached, can further improve the accuracy of the workpiece. Both pressure maintaining and pressure reducing can be commanded and controlled through the proportional directional valve. Customize the running cycle time as needed. When pressure reduction is required, it can be minimized as much as possible, but the pressure reduction curve should not be too steep and should be as stable as possible.
How to distinguish the quality of pipe bending machines
1. The hardness of the mold base and mold is also the key to the normal use of the equipment in the future. When the hardness of the mold seat is lower than Rockwell HRC60 and the hardness of the mold is lower than Rockwell HRC50, it will affect the clamping quality of the rubber hose.
2. Measure the main parameters of the equipment: Leave the equipment in an idle state, touch each mold block with your hand, and there should be no shaking in the feel. Otherwise, it will be considered a non-conforming product.
3. Install the equipment into a mold, press a sample joint, and measure the clamping joint with a caliper or micrometer. The roundness and taper should be within 0.1mm, which is considered excellent.
