风管加工机械咬口机的技术要求!

发布时间:2020/03/12

1. 咬片厚度应在各种规格规定的范围内。如果小于更小厚度,在咬入过程中容易产生裂纹、起皱等缺陷。如果厚度大于厚度,由于板厚与平方成正比,弯曲力的明显增大会对成形辊造成异常损伤,使传动系统过载而发生故障。
1. The thickness of undercut shall be within the range specified by various specifications. If it is less than the minimum thickness, it is easy to produce cracks, wrinkles and other defects during the biting process. If the thickness is greater than the maximum thickness, because the thickness of the plate is proportional to the square, the obvious increase of bending force will cause abnormal damage to the forming roll, which will overload the transmission system and cause failure.
2. 咬口机的加工能力是根据普通钢板的加工而设计的,常用的普通钢板、镀锌钢板和塑料复合钢板具有良好的咬口成型性能。不锈钢板的强度应高于普通钢板,在使用不锈钢板咬之前,首先要做成形试验,以免使设备超负荷工作,造成过度磨损或机械事故。由于铝板塑性差,易开裂咬口成型,施工前也要做成型试验,同时,由于铝板缺乏弹性,铝板风道不能按键式咬口。
2. The processing capacity of the undercut machine is designed according to the processing of ordinary steel plate. The common ordinary steel plate, galvanized steel plate and plastic composite steel plate have good undercut forming performance. The strength of stainless steel plate shall be higher than that of ordinary steel plate. Before using stainless steel plate to bite, the forming test shall be carried out first to avoid overload of equipment and excessive wear or mechanical accident. Due to the poor plasticity of the aluminum plate, it is easy to crack and form the undercut. Before construction, it is also necessary to conduct the forming test. At the same time, due to the lack of elasticity of the aluminum plate, the aluminum plate air duct cannot be button type undercut.
3.板咬入部分的更小长度不小于300mm。否则,水平阻力引起的板咬太少接触板和成型辊的摩擦力大于喂食板,导致板成型辊之间的滑移和加速形成的磨损辊的一部分。
3. The minimum length of the bite part of the plate shall not be less than 300 mm. Otherwise, the friction between the forming roll and the plate caused by the horizontal resistance is greater than that of the feeding plate, which leads to the slippage between the forming rolls and the accelerated formation of a part of the wear roll.

4. 使用前,进给导轨的调试应严格按照设备的调试要求进行,调整到规定的位置和尺寸后将进给导轨固定。如果进给导轨的实际位置小于规定的位置尺寸,则咬口不成形。如果它的尺寸大于规定的位置尺寸,则咬入的尺寸是超差的,因为进给过宽,导致两块板不能咬入或浪费材料;当进给钢轨严重歪斜时,容易产生咬入宽度不均匀的偏差缺陷。
4. Before use, the feed guide rail shall be debugged in strict accordance with the debugging requirements of the equipment, and the feed guide rail shall be fixed after being adjusted to the specified position and size. If the actual position of the feed guide rail is less than the specified position size, the undercut will not be formed. If its size is larger than the specified position size, the bite size is out of tolerance, because the feed is too wide, resulting in two plates can not bite or waste materials; when the feed rail is seriously skewed, it is easy to produce deviation defects with uneven bite width.
5. 上、下成型辊径向预留间隙的调整,不仅要求适当的松紧,而且要一致。如果预留间隙太小,喂食困难,即使强行进入,咬痕开裂严重;如果间隙过大,则会导致在成形辊中出现不规则的咬形或卡瓦。使用不锈钢板或铝板咬口时,径向预留间隙应大于相同厚度的钢板间隙调整,否则会造成设备过载或咬口开裂现象
5. The adjustment of the radial reserved clearance of the upper and lower forming rollers requires not only proper tightness, but also consistency. If the reserved gap is too small, feeding is difficult, even if forced entry, the bite marks will crack seriously; if the gap is too large, irregular bite or slip will appear in the forming roll. When stainless steel plate or aluminum plate is used for undercut, the reserved radial clearance shall be greater than the clearance adjustment of steel plate with the same thickness, otherwise the equipment will be overloaded or the undercut will crack
