Abstract
A kind of drive plate heat-treatment processing process, belongs to automobile clutch field.The object of the present invention is to provide a kind of elder generation is quenched, rear punching, increase blanking punching centre bore and the drive plate heat-treatment processing process of tempering smoothing two procedures.The process step of the invention is：Preceding cleaning, rear cleaning, tempering for the first time, high tempering, is transferred to punching press at heating quenching, rushes all holes, heat treatment destressing tempering.Present invention process is simple, easily operated, do over again reprocessing once there is unqualified can smooth again of flatness, significantly reduces rejection rate.
Description
Technical field
The invention belongs to automobile clutch fields.
Background technology
Drive plate in automobile clutch is the critical component in entire clutch, it directly affects the performance of clutch,
The existing treatment process for drive plate be usually first it is quenched after be tempered, this processing technology by very big required precision, once
It machines and substandard product occurs, can only just scrap can not be reprocessed, and cause a large amount of rejection rate, and waste is very big.
Invention content
The object of the present invention is to provide a kind of elder generation is quenched, rear punching, increase blanking punching centre bore and tempering smoothing twice work
The drive plate heat-treatment processing process of sequence.
The process step of the invention is：
A, preceding cleaning：Drive plate is worn material feeding rod to hang on rack, is cleaned 20 minutes；
B, heating-quenching：By cleaned drive plate rack, Sealing furnace station is transferred to, sets heating temperature 810~830
DEG C, 920 DEG C of charging temperature, carbon potential 0.6 ± 0.05%, 10 minutes heating times, soaking time 10 minutes quench oil temperature 110
It~130 DEG C, quenches 15 minutes, leaching oil 15 minutes, 100~300Pa of furnace pressure；
C, rear cleaning：Cleaning machine is transferred to after the completion of quenching to be cleaned, and is cleaned 20 minutes；
D, it is tempered for the first time：Drive plate after cleaning is transferred to tempering removal quenching stress, furnace temperature 200 in tempering furnace
~230 DEG C；
E, high tempering：Neatly packed penetrate of drive plate is tempered in pressure tire, with from weight tire pressure reality, hangs in the tempering of well formula
Stove high temperature is tempered, 570~640 DEG C of temperature, keeps the temperature 5 hours, is opened fire door and is cooled down in stove；Less than 50 DEG C are cooled to go out
Stove, workpiece are dismantled when being cooled to room temperature from weight tire；
F, punching press is transferred to, rushes all holes；
G, heat treatment destressing tempering：Neatly packed penetrate of drive plate is tempered in pressure tire, with from weight tire pressure reality, is hung in
Well formula tempering furnace high temperature is tempered, 400~450 DEG C of temperature, keeps the temperature 3 hours, is opened fire door and is cooled down in stove；It is cooled to 50
It comes out of the stove below DEG C, workpiece is dismantled when being cooled to room temperature from weight tire.
Present invention process is simple, easily operated, do over again reprocessing once there is unqualified can smooth again of flatness,
Significantly reduce rejection rate.
Specific embodiment
The process step of the invention is：
A, preceding cleaning：Drive plate is worn material feeding rod to hang on rack, is cleaned 20 minutes；
B, heating-quenching：By cleaned drive plate rack, Sealing furnace station is transferred to, sets heating temperature 810~830
DEG C, 920 DEG C of charging temperature, carbon potential 0.6 ± 0.05%, 10 minutes heating times, soaking time 10 minutes quench oil temperature 110
It~130 DEG C, quenches 15 minutes, leaching oil 15 minutes, 100~300Pa of furnace pressure；
C, rear cleaning：Cleaning machine is transferred to after the completion of quenching to be cleaned, and is cleaned 20 minutes；
D, it is tempered for the first time：Drive plate after cleaning is transferred to tempering removal quenching stress, furnace temperature 200 in tempering furnace
~230 DEG C；
E, high tempering：Neatly packed penetrate of drive plate is tempered in pressure tire, with from weight tire pressure reality, hangs in the tempering of well formula
Stove high temperature is tempered, 570~640 DEG C of temperature, keeps the temperature 5 hours, is opened fire door and is cooled down in stove；Less than 50 DEG C are cooled to go out
Stove, workpiece are dismantled when being cooled to room temperature from weight tire；
F, punching press is transferred to, rushes all holes；
G, heat treatment destressing tempering：Neatly packed penetrate of drive plate is tempered in pressure tire, with from weight tire pressure reality, is hung in
Well formula tempering furnace high temperature is tempered, 400~450 DEG C of temperature, keeps the temperature 3 hours, is opened fire door and is cooled down in stove；It is cooled to 50
It comes out of the stove below DEG C, workpiece is dismantled when being cooled to room temperature from weight tire.
The present invention will be described in detail below：
After the blanking punched punching (slot) of the present invention, after heat treatment carries out quenched processing, return punching press and gone out position degree
It is required that hole position, finally tempering heat treatment smooth.
