Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.

As shown in fig. 1 to 15, the steel-plastic composite control arm comprises a stamped sheet metal body 2 and a body 2 injection-molded part 6 for reducing weight, and further comprises a first shaft sleeve 1, a second shaft sleeve 3, a third shaft sleeve 5 and a central plastic hole 4 which are respectively welded at three end parts and a central point of the sheet metal body 2, wherein the injection-molded part 6 is provided with a plurality of groups of reinforcing ribs 7 which are connected with each other.

As shown in fig. 12, the body 2 is provided with a protrusion 21 engaged with the injection molding member 6 and a semicircular ring 22 engaged with the first sleeve 1, the second sleeve 3 and the third sleeve 5.

The injection-molded part 6 is provided with a concave ring 61 which is matched with the bulge 21 and a clamping claw 62 which is matched with the central plastic hole 4.

The concave ring 61 is arranged at the joint of the reinforcing ribs 7 on the injection molding part 6.

The utility model combines the stamping, welding and injection molding; welding the stamped sheet metal part body 2 with the first shaft sleeve 1, the second shaft sleeve 3, the third shaft sleeve 5 and the central plastic hole 4, and then placing the welded sheet metal part body into an injection molding die cavity for injection molding; sheet metal material: SPFH780, stock thickness: 1.2 mm; shaft sleeve material: 20 #; plastic material: PA6/GF50, thickness: 2.5 mm.

As shown in fig. 7, on one end face of the reinforcing rib 7, the injection-molded part 6 is fastened to the central plastic hole 4 of the body 2 by means of a catch 62.

Because the phase transformation coefficients of the plastic and the steel are different by one grade, the reliability of the connection of the plastic and the steel is very important, and the reliability of the connection is enhanced by the bowl-shaped connection, the I-shaped matching and the punching and edge covering structural design between the body 2 and the injection molding part 6.

As shown in fig. 11, the joint of the body 2 and the injection molding part 6 is in an i-shaped fit, and the body 2 is clamped on the injection molding part 6.
