(1)钳口夹持质量对5052铝板拉伸品质起着决定性的作用，钳口的均匀夹持使板材纵向每一个单元都被拉伸到等量长度，从而实现均匀拉伸，起到了对板材的矫直作用。
(1) The clamping quality of the jaw plays a decisive role in the tensile quality of 5052 aluminum plate. The uniform clamping of the jaw makes each unit of the plate be stretched to the same length in the longitudinal direction, so as to realize the uniform stretching and straighten the plate.
(2)拉伸机机架的刚度与预变形补偿的影响：由于板材拉伸机的两个拉力缸  等量安置在两侧，对于横截面越大的板材，在拉伸过程中机架产生的变形也越大。因此，拉伸机机架应保持更大的刚度，设计与制造中应考虑机架预变形偿，以克服和补偿拉伸过程中机架产生的变形。
(2) Influence of frame stiffness and pre deformation compensation: because the two tension cylinders of the plate drawing machine are equally placed on both sides, the larger the cross section of the plate, the greater the deformation of the frame during the drawing process. Therefore, the frame of the drawing machine should maintain greater stiffness, and the pre deformation compensation of the frame should be considered in the design and manufacture, so as to overcome and compensate the deformation of the frame during the drawing process.

(3)拉伸前5052铝板板材尺寸的不规则性和应力分布的不均匀性，拉伸过程中有效地控制平稳的速度，使各个变形单元得以充分均匀地变形，是满足均匀拉伸的重要
(3) Before drawing, the size of 5052 aluminum plate is irregular and the stress distribution is non-uniform. In the drawing process, it is important to control the smooth speed effectively so that each deformation unit can deform fully and evenly
(4)实践证明，长度相对小一些，宽度相对大一些的板材，其横向展平效果  条件之一要好得多。生产中应选择宽、长比大一些的工艺方案。
(4) Practice has proved that the transverse flattening effect of plates with relatively small length and large width is much better. In the production, the process plan with larger ratio of width to length should be selected.
(5)对淬火后变形较大的板材，应利用辊式矫直机初步矫平，而后在拉伸机上进行终的精矫平。
(5) For the plate with large deformation after quenching, the roller straightener should be used for preliminary leveling, and then the final fine leveling should be carried out on the drawing machine.
(6)由于拉伸机的主要作用是消除板材的残余应力，以纵向小变形量的塑性  变形过程为主，因而对纵向有更好的矫直作用，对横向平直度的改善能力非常有限。
(6) Because the main function of the drawing machine is to eliminate the residual stress of the plate, the plastic deformation process with small longitudinal deformation is the main process, so it has a better straightening effect on the longitudinal direction, and its ability to improve the transverse flatness is very limited.
