Problems solved by technology

The hollow pedal arm is stamped and welded to form a hollow tube. Compared with the solid pedal, the hollow pedal reduces the weight and production cost, but due to the welding stress, the strength of the pedal body is reduced, and there are potential safety hazards.

Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0030] A pedal arm manufacturing process, the specific manufacturing process steps are as follows:

[0031] (1) blanking: according to the size of the pedal arm 2, select steel plate blanking;

[0032] (2) Punching process: according to the arrangement of the blanks, use the blanking die to punch out the steel sheet blanks into a shape with a reasonable flanging size;

[0033] (3) Stamping forming: using a stamping die to stamp and form the blanked plate;

[0034] (4) Hemming process: fasten and bend the two formed single-side pedal arms 2 through the hemming machine.

[0035] like Figure 1 to Figure 10 As shown, a kind of automobile brake pedal using the pedal arm in the pedal arm manufacturing process includes a pedal b...

Abstract

The invention relates to the technical field of auto parts, specifically a pedal arm manufacturing process and an automobile brake pedal using the pedal arm. The specific manufacturing process steps are as follows: blanking: according to the size of the pedal arm, select steel plate blanking; Cutting processing: According to the arrangement of the blanks, use the blanking die to punch out the steel sheet blanks into a shape with a reasonable flanging size; Stamping forming: Use the stamping die to stamp the blanked plates; Hemming process: Fasten and bend the two formed one-sided pedal arms through the edge binding machine. Compared with the solid pedal arm, the invention reduces the weight. Compared with the welded hollow pedal arm, the hemmed hollow pedal arm reduces the welding process, increases the hemming process and reduces the cost. At the same time, the appearance of the hemmed hollow pedal arm is more beautiful than that of the welded hollow pedal arm. , no welding slag, weld burrs, and no welding stress, and its strength is much higher than that of welded hollow pedal arms.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a pedal arm manufacturing process and an automobile brake pedal using the pedal arm. Background technique [0002] As the main safety component of the car, the car brake pedal is mainly used for deceleration and parking. It is one of the five major controls of the car. The frequency of use is very high, so there are high requirements for its strength and safety performance. Traditional brake pedals in the market are mainly divided into solid pedal arms and hollow pedal arms. The hollow pedal arms are stamped and bent directly from thick steel plates. The hollow pedal arm is stamped and welded to form a hollow tube. Compared with the solid pedal, the hollow pedal reduces the weight and production cost, but the strength of the pedal body is reduced due to the welding stress, which poses a safety hazard. Contents of the invention [0003] In order to solve the above t...
