The nut comprises a head flange and a rod part connected with the head flange, wherein a pluralityof linear straight teeth are arranged on the rod part, the brake caliper connecting nut is provided with an inner hole penetrating through the head flange and the rod part in the axis direction, thedevice comprises a first die, a second die, a fourth die, a fifth die and a sixth die, and straight teeth of the nut can be formed on the rod part of the nut through the sixth die. The scheme has theadvantages of improving the production efficiency and precision, reducing the material cost and the like.

Description

technical field [0001] The invention relates to the technical field of cold heading dies, in particular to a brake caliper connecting nut, a preparation device and a preparation method thereof. Background technique [0002] The brake caliper connection nut is a nut used on the brake system of the car, which is installed on the brake caliper and used to fix the caliper on the brake frame to ensure that the caliper is firmly fixed on the car. The common preparation method of the existing brake caliper connecting nut is: first cold heading the wire rod into a semi-finished product, the semi-finished product includes a solid rod part and a head connected thereto, and then knurling the solid rod part to form a tooth part. This method has the following disadvantages: [0003] 1. The tooth part is formed by knurling, the size of the tooth part is unstable, the precision is poor, the processing time is long, and the efficiency is low. [0004] 2. The rod is a solid structure, whic...
