穿條機穿出來的料彎曲的原因主要包括以下幾個方面：

　　The reasons for the bending of the material produced by the threading machine mainly include the following aspects:

　　輥輪調整不當：穿條機上的輥輪是鋁材彎曲的主要原因之一。如果輥輪的位置和角度調整不正確，會導致鋁材在擠壓過程中產生彎曲。解決方法是調整輥輪的高度和角度，確保其與鋁材的彎曲方向相反，從而產生反作用力，減少彎曲。

　　Improper adjustment of rollers: The rollers on the threading machine are one of the main causes of aluminum bending. If the position and angle of the roller are not adjusted correctly, it will cause the aluminum material to bend during the extrusion process. The solution is to adjust the height and angle of the roller to ensure that it is opposite to the bending direction of the aluminum material, thereby generating a reactive force and reducing bending.

　　導軌安裝不正確：導軌在穿條機中起到引導鋁材運動的作用。如果導軌的安裝位置或角度不正確，鋁材無法順利通過，容易發生彎曲。解決方法是將導軌調整到與鋁材的彎曲方向垂直，并調整到恰當的高度，使之與輥輪協同作用，減少彎曲。

　　Incorrect installation of guide rail: The guide rail plays a role in guiding the movement of aluminum material in the threading machine. If the installation position or angle of the guide rail is incorrect, the aluminum material cannot pass smoothly and is prone to bending. The solution is to adjust the guide rail to be perpendicular to the bending direction of the aluminum material and to the appropriate height, so that it cooperates with the roller to reduce bending.

　　送料裝置調整不當：送料裝置的調整也會影響鋁材的彎曲情況。如果送料裝置的高度或位置不正確，會導致鋁材在穿條機上位置不當，從而引起彎曲。解決方法是調整送料裝置的高度和位置，使之與導軌和輥輪的作用協同起來，減少彎曲。

　　Improper adjustment of the feeding device: The adjustment of the feeding device can also affect the bending of the aluminum material. If the height or position of the feeding device is incorrect, it can cause the aluminum material to be improperly positioned on the threading machine, resulting in bending. The solution is to adjust the height and position of the feeding device so that it works in conjunction with the guide rails and rollers to reduce bending.

　　預防和解決穿條機穿出來的料彎曲問題的方法包括：

　　The methods to prevent and solve the problem of material bending caused by the threading machine include:

　　確保擠出機全線的同心度和水平度，每次更換模具時都應對擠出機、口模、定型模、水箱等的同心度和水平度進行校正。

　　Ensure the concentricity and levelness of the entire extruder line, and calibrate the concentricity and levelness of the extruder, die, shaping die, water tank, etc. every time the mold is replaced.

　　調整定型模的冷卻系統，加大型材承受拉伸應力一側的冷卻水量。

　　Adjust the cooling system of the shaping mold and increase the amount of cooling water on the side of the profile that bears tensile stress.

　　采用機械偏移中心的方法調整，即一邊生產一邊調整定型模中間的定位螺栓，依據型材彎曲方向進行反向微量調整。

　　Using the method of mechanical offset center adjustment, that is, adjusting the positioning bolts in the middle of the shaping mold while producing, and making reverse micro adjustments according to the bending direction of the profile.
