1. The Q345B square steel pipe has sufficient clearance and the internal tightness and looseness of the roll gap plan does not seem to be suitable.
2, too much oil in the car or excessive frequent brushing and mouthwashing, or poor brushing and mouthwashing is the part of Q345B square steel tube.
3, it is the raw material of Q345B square steel tube blank test that is too soft and low compressive strength in single pulse. The 16mn seamless square tube blank has very small specifications. The main feature of precision seamless steel tube is the raw material HID.
4, the rough and precise positioning is not stable, causing part of the raw materials to be hidden, and the occlusal surface of the teeth is not good, resulting in uneven feeding of materials on foot.
5 unsuitable stamping die orientation.
Using Q345B square steel pipe to wrinkle countermeasures: 1. Check the wrinkle situation, even when the wrinkle is caused in a part, the periphery is clearly lower than
Analysis of the causes of wrinkling of Q345B square steel pipes and preventive measures
Q345B square steel pipe wrinkles what is going on:
1, the Q345B square steel pipe has sufficient gaps and the internal tightness and looseness of the roll gap plan does not seem to be suitable.
2, too much car oil or too frequent tooth brushing and mouthwashing frequency, 16mn seamless square tube or poor tooth brushing and mouthwashing is the Q345B square steel tube part.
3, it is the raw material of Q345B square steel tube blank test that is too soft and low compressive strength in single pulse. The blank size is very small, and the raw material is HID.
4, the rough and precise positioning is not stable, causing part of the raw materials to be hidden, and the occlusal surface of the teeth is not good, resulting in uneven feeding of materials on foot. 5 The orientation of the stamping die that is not suitable.
Manipulate Q345B square steel tube wrinkle countermeasures:
1. Inquire about the wrinkle situation, even when the 16mn seamless square tube causes wrinkles in a part, the periphery is clearly lower than the clamping force, and the nip force gradually increases. The main feature of precision seamless steel pipe is that it can be used. When drawing cones and hemispherical prefabricated components should be lifted to increase the inner diameter of the above-mentioned side beams, the folds are used to draw the tendons to stretch the ground stress. It is difficult to choose the standard of loosening after tightening, so as to loosen after tightening.
2. For grease, oil brush work should be carried out in accordance with the standard system requirements to ensure that the oil and carbon brushes and the appropriate parts of the carbon brush oil, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn Square tube-Shandong Dingyu Metal Material Co., Ltd. to prevent wrinkles.
