The invention discloses a connecting structure of a front forklift head tube and a lower steel bowl assembly and a manufacturing process, the connecting structure is composed of a front forklift head tube, a lower steel bowl, a lower bearing and a lower stopper, the front forklift head tube is connected with the lower steel bowl, the lower bearing is arranged in the lower steel bowl, the lower stopper is arranged below the lower bearing, the lower steel bowl comprises a tube head, a bearing seat and a step, and the step is connected with the lower steel bowl. The front fork head tube is characterized in that one end of the front fork head tube is provided with 1-N notches; 1-N outer convex blocks are arranged on the step of the lower steel bowl; two symmetrical inner convex blocks are arranged on the inner side of the round opening of the bearing seat of the lower steel bowl; the outer edge of the base plate of the lower stopper is provided with two symmetrical convex stopper pieces, and the notch, the outer convex block and the inner convex block are all completed through a stamping process, and the front fork vertical pipe and the lower steel bowl are in fixed connection in the plane position due to the fact that the outer convex block is completely inserted into the notch, and the plane displacement phenomenon cannot occur any more; the inner protruding block of the lower steel bowl and the protruding blocking piece of the lower blocking piece are located on the same plane, and the rotation direction of the front wheel can be limited within a certain rotation angle range.

    本发明公开了一种前叉车头管和下钢碗组件的连接结构和制造工艺,由前叉车头管、下钢碗、下轴承和下档组成,前叉车头管连接下钢碗,下钢碗内有下轴承,下轴承下面有下档,所述的下钢碗包括管头、轴承座和台阶,其特征在于:所述的前叉车头管的一端有1∽N个缺口;所述下钢碗的台阶上有1∽N个外凸块;下钢碗的轴承座圆口内侧有2个对称的内凸块;所述下档的底盘外边上有2个对称的凸档片,所述的缺口、外凸块、和内凸块都用冲压工艺完成的,有益效果是:所述的外凸块完全插入缺口内,使前叉立管与下钢碗在平面位置上实现死连接,不会再有平面位移现象的出现;所述的下钢碗的内凸块和下档的凸挡片,在同一平面上,可以限制前轮转动方向在一定转角范围。
