这种结构的模具在使用中企口角钢起到增加刚性、提高强度、增强合口密封的作用。因此,其制作的好坏,直接影响到模具的使用寿命。 有些厂家在制造中采用单根角钢压制成型,这 样,角钢容易变形,造成企口角钢不能与简壁贴紧, 影响桩模质量,影响生产效率。 本人根据几年来我厂生产的经验,介绍一种压制企口角钢的方法,供同行参考。 在压制前先将角钢钻塞焊孔,钻好后,将上下两片角钢点焊在一起,然后放在压模（见图）中用压机 进行压制。压模的圆弧直径要比实际直径小些（约 20mm）,以便回弹。这样,基本上就能一次成型。既节省了工时,提高了工效,同时又保证了桩模质量。这会给厂家带来很好的经济效益。这种结构的模具在使用中企口角钢起到增加刚性、提高强度、增强合口密封的作用。因此,其制作的好坏,直接影响到模具的使用寿命。 有些厂家在制造中采用单根角钢压制成型,这样,角钢容易变形,造成企口角钢不能与筒壁贴紧,影响桩模质量,影响生产效率。 本人根据几年来我厂生产经验,介绍一种压制企口角钢的方法,供同行参考。 在压制前先将角钢钻塞焊孔,钻好后,将上下两片角钢点焊在一起,然后放在压模（见图）中用压机进行压制。压模的圆弧直径要比实际直径小些（约20mm）
The structure of the mold in the use of angle steel to play to increase rigidity, increase strength, enhance joint sealing effect. Therefore, the quality of its production directly affects the service life of the mold. Some manufacturers use a single angle steel for forming in the manufacturing process. In this way, the angle steel is easily deformed, resulting in that the angle steel cannot be tightly attached to the simple wall, affecting the quality of the pile mold and affecting the production efficiency. Based on my factory’s production experience over the past few years, I introduced a method of suppressing Qikou angle steel for reference by peers. Before the pressing, the angle steel is drilled and the hole is drilled. After drilling, the two upper and lower angles are spot-welded and then pressed in a die (see figure). The diameter of the circular arc of the die is smaller (about 20mm) than the actual diameter in order to rebound. In this way, it is basically possible to mold once. It not only saves man-hours and improves work efficiency, but also ensures the quality of the pile and die. This will bring great economic benefits to the manufacturers.

Some manufacturers use a single angle steel in the production of the press molding, so that the angle steel is easily deformed, resulting in the angle of the enterprise can not be tight with the cylinder wall, affecting the quality of the pile, affecting the production efficiency. Based on my factory’s production experience over the past few years, I introduced a method for suppressing the angle steel of Qikou for reference by peers. Before the pressing, the angle steel drill plugs are used to weld the holes. After drilling, two upper and lower angles of steel are spot welded together and then pressed in a die (see figure). The arc diameter of the die is smaller than the actual diameter (about 20mm)
