720AB中频加热弯管机是我们引进的设备。该设备上装有防止椭圆的压辊及夹具。为了提高我国现有弯管设备产品的质量,可以在原有的设备基础上增设上述的压辊及夹具,便可达到减少椭圆、提高产品质量的目的。现将压辊及夹具介绍如下: 一、防止椭圆的压辊管子加热弯曲时,由于受力的关系,会减少有效管截面,形成椭圆,从而增加了流动阻力。为了防止椭圆的产生,可以在管子弯曲加热后,距其250mm左右的位置,在垂直方向上下给一个夹紧力,使管子产生逆椭圆。
720AB IF heating pipe bender is our introduction of equipment. The device is equipped with a roll and clamp to prevent oval. In order to improve the quality of our existing pipe bending equipment products, we can achieve the purpose of reducing the oval and improving the product quality by adding the above-mentioned pressure rollers and clamps on the basis of the original equipment. The pressure roller and fixture are introduced as follows: First, to prevent the oval roller heat pipe bending, due to the force relationship, will reduce the effective pipe cross-section, the formation of oval, thereby increasing the flow resistance. In order to prevent the generation of oval, you can bend the pipe heating, about 250mm away from its position, in the vertical direction to give a clamping force, so that the tube produces an inverse oval.
