Abstract
The invention provides a processing technology method for a hollow pedal rocker arm, wherein a steel pipe is taken as a raw material. The processing technology method is implemented through the following steps: (1) blanking: blanking with the steel pipe according to the size of the pedal rocker arm to form a pipe fitting; (2) expansion processing: using a piece of expansion equipment to process the steel pipe into a reducer; (3) flattening forming: flattening the reducer into a flat pipe; (4) bend forming: forming the flat pipe into a semi-finished product of the hollow pedal rocker arm in the length direction in a bending way; (5) press forming and drilling: forming the semi-finished product of the hollow pedal rocker arm in a press way, and then drilling to obtain the final hollow pedal rocker arm. According to the processing technology method, the steel pipe is creatively used for processing the pedal rocker arm to form the hollow pedal rocker arm; and compared with an existing pedal rocker arm, the weight of the hollow pedal rocker arm is reduced by at least 50%, so that the material consumption is greatly reduced, and the follow-up performance of the pedal rocker arm is improved.
Description
Technical field
The present invention relates to automobile brake clutch pedal assembly field, especially a kind of technological method for processing of hollow pedal rocking arm.
Background technology
The pedal rocking arm is the parts of automobile brake clutch pedal assembly.Present pedal rocking arm, employing be the thick steel plate manufacturing of millimeter, but product material consumption is large, product weight is large, in the total travel use procedure, servo-actuated property is poor cause insensitive, inertia destroys greatly large to the switch original paper, the large increase complete vehicle quality of weight, and product appearance is of poor quality simultaneously.
Summary of the invention
In order to realize the lightweight of pedal rocking arm, cutting down the consumption of raw materials improves the servo-actuated performance of pedal rocking arm, and the present invention proposes a kind of technological method for processing of hollow pedal rocking arm.
For this reason, the present invention by the following technical solutions: a kind of technological method for processing of hollow pedal rocking arm, the employing steel pipe is raw material, realizes by above step:
(1). blanking: according to the size of pedal rocking arm, use steel pipe blanking, become pipe fitting;
(2). swollen type processing: utilize swollen type equipment that steel pipe is processed into reducer pipe;
(3). press flat forming: reducer pipe is flattened, become flat tube;
(4). bending forming: along its length with the flat tube bending forming, become hollow pedal rocking arm semi-finished product;
(5). press shaping die and boring: behind hollow pedal rocking arm semi-finished product press shaping die, boring forms final hollow pedal rocking arm again.
Beneficial effect: the employing steel pipe of the present invention's innovation comes the machining pedal rocking arm, becomes hollow pedal rocking arm; Its weight is compared with existing pedal rocking arm, reduces at least 50%, has significantly reduced material consumption, has improved the servo-actuated performance of pedal rocking arm.
