Description
Technical field
The present invention relates to auto parts production technical fields, and more specifically more particularly to a kind of auto parts and components rush
Pressure method.
Background technology
Punching press is that depended on pressure machine and mold apply external force to plank, band, tubing and proximate matter etc., is allowed to generate plastic deformation
Or separation, to obtain the stamping parts of required shape and size.The blank of punching press is mainly the steel plate and steel band of hot rolling and cold rolling.
In global steel, 60~70% be plank, and finished product is made by punching press in wherein most.Especially in automotive field, vapour
Vehicle body, chassis, fuel tank, the radiator fin of vehicle, the drum of boiler, the shell of container, motor, electric appliance iron core silicon-steel sheet etc. all need
Want punch process.But often occur this kind of complex-shaped workpiece of some problems, especially cooling fin in carrying out punching course,
It carries out usual when stamping procedure
Stamping equipment will carry out Multi-step forming to punch die, this allows for the phenomenon that die wear is serious, and blade is easily passivated, makes
Generate a large amount of burrs at workpiece after punching press, and the generation of burr can cause workpiece when deform process due to generation stress concentration and
Cracking, can also influence subsequent welding procedure, while big burr also easily scratches operator, and there are security risks, for this purpose, we
It is proposed a kind of process for stamping of auto parts and components.
Invention content
The purpose of the present invention is to solve disadvantage existing in the prior art, and a kind of auto parts and components for proposing rush
Pressure method reduces the welding procedure of the more efficient multiple-printed-panel for circuit board mode and connector of product rejection rate.
To achieve the above object, the present invention provides the following technical solutions：A kind of process for stamping of auto parts and components, including such as
Lower step：
S1, selection：Different plank blanks, plank is used to have according to different auto parts and components：Aluminum alloy plate materials and clad steel
Plank；
S2, prepare mold：Upper mold and lower mold are checked before carrying out punching press, record diel inner wall abrasion feelings
Condition, and replace wear more serious upper mold and lower mold in time, then the position of upper mold and lower mold is adjusted, and fixed upper mold
Tool and lower mold complete the preparation of upper mold and lower mold；
S3, stamping equipment is checked：Stamping equipment is checked before carrying out punching press, checks edge wear situation, and by upper mold
Tool is fixed with punch rod, and lower mold is fixed with punching machine；
S4, mold oil supply：It is uniformly dripped by the upper mold of diel and lower mold separation, and along the lower mould side wall of diel
Add lubricating oil, then starts stamping equipment, the upper mold of diel and the unloaded punching press of lower mold progress are primary, observe stamping die
Tool inner surface whether smoothen lubricating oil, if lubricating oil smear uniformly if complete diel give oil processing, if range estimation smear not
It is primary that the uniform then upper mold of diel and lower mold carry out unloaded punching press again, if lubricating oil still smears unevenness after unloaded twice
It is even, then lubricating oil is dropped evenly again in lower mould side wall, then carry out unloaded punching press, until lubricating oil is smeared uniformly；
S5, punching press：Blank is positioned over bottom mold surface, adjusts drawing velocity and punching stroke, starts stamping equipment and is rushed
Press process, upper mold and lower mold are combined closely 20~40s of holding, then cavity plate and punch-pin are detached, then by stamped workpieces
From lower mold ejection and it is detected；
S6, detection：The workpiece of taking-up is detected, whether detection surface keeps preferable quality, the whether smooth light of appearance
It is sliding.
Preferably, the structural strength of mold is improved, die surface cure process is improved, increases the service life of mold.
Preferably, lubricating oil includes the raw material of following parts by weight：82 parts of base oil, 3 parts of nano tungsten carbide, two sulphur of nanometer
Change 4 parts of molybdenum powder, 2 parts of carbon black, 1 part of quinazoline corrosion inhibiter, 0 .3 parts of flow point improver, 2 parts of dispersant.
Preferably, when giving oil processing, the operation for carrying out that lubricating oil is added dropwise, and follow-up profit are needed after often running unloaded punching press twice
The dropwise addition volume of lubricating oil is that the 10%~25% of volume is added dropwise for the first time.
The technique effect and advantage of the present invention：
1, so that stamping equipment and the performance of diel stabilization, avoid plant issue from generating stamping procedure in punching course
It influences；Can both have been reduced the frictional resistance that diel generates in punching course to oil processing to diel, simultaneously
Polishing scratch tiny in diel can be smoothed, enhance the wear-resisting property of diel, can also be subsequent workpiece blanking
Process provides advantage.
2, using lubricating oil to increase the wear-resisting property and dispersion performance of mold, and lubricating oil is made to be dispersed in punching press
Mould inner surface reduces wear rate, reduces the generation of workpiece surface burr, improves the safety of punching course.
