Embodiment Construction

[0017] The steps of the present invention are:

[0018] (1) Prepare 65Mn steel strip in spheroidizing annealed state, width 226mm, thickness 0.80mm, hardness 100-130HV 30 .

[0019] (2) Stamping processing flat material, using conventional stamping method for material processing, the process is punching - punching groove - punching center hole - blanking; the place that is different from the original process is the last sequence of blanking No molding of the integral corrugated sheet is required. The blanking will be described in detail below.

[0020] (3) Overall corrugated sheet quenching:

[0021] a. Loading and cleaning: Put the punched workpieces on the load beam evenly at intervals of 500 pieces per furnace to ensure that the blanking direction of the workpieces is in the same direction, put the loaded beams on the heating fixture, and use a conveying vehicle Send the heating jig full of workpieces to the cleaning station, open the front door of the washing machine, ...

Abstract

The invention relates to an overall waveform piece machining technology for an automobile clutch, and belongs to the technical field of clutch machining. The overall waveform piece machining technology comprises the steps that a 65 Mn steel belt in the spheroidizing annealing state is prepared, and procedures including punching, necking, center hole punching and blanking are carried out; overall waveform piece quenching is carried out, wherein feeding washing, quenching and post washing are carried out; and tempering leveling, tempering molding and anti-rusting treatment are carried out. The overall waveform piece machining technology has the beneficial effects that eight waveforms are formed on a circumference of an overall waveform piece, and the mold height can meet the requirement forcoincidence. Compared with an overall waveform piece machined through original technology by means of axial compression endurance tests, the fatigue decrement is reduced.

Description

technical field [0001] The invention belongs to the technical field of clutch processing. Background technique [0002] One of the functions of the clutch is to ensure the smooth start of the car. During the coupling process of the clutch, the wave plate plays the role of axial vibration reduction, and the wave plate is divided into two types in structure, integral type and split type. The corrugated sheet is mainly subjected to alternating loads, impact loads, and shear stresses, so it is easy to produce fatigue attenuation and cause the car to start shaking. The material used for the corrugated sheet is 65Mn, which requires high elastic limit, yield strength and fatigue strength. [0003] At present, the processing technology of the overall corrugated sheet is punching - punching groove - punching center hole - blanking forming - heat treatment tempering - rust prevention, the raw material is heat treatment steel strip, width 226mm, thickness 0.8mm, hardness 440-485 HV 3...
