Description
Technical field
The present invention relates to a kind of auto parts and components production method, the production method belongs to technology field, specially automobile zero
Part production field.
Background technology
Automobile is widely used a kind of vehicles in the modern life, and it is changing our life, in order that automobile
Attractive in appearance, safety obtains purpose, and the parts application of flanging and restriking is more universal, and the method that auto parts and components make all is by many
Mold is produced, and typically sawing --- drawing ----multistep mould pressing mold shaping (needs many pre- pressing molds of set and final pressure
Mould) step such as --- die punching --- mould trimming.Because the making of precision die is more complicated, early stage more needs the long period to discuss
The dimensional parameters of mould are changed, the manufacturing cycle is long, high cost, high using Object Selection, changes dumb (even if parts locally
There is small change in size, mould originally is also no longer applicable, it is necessary to prepare again), this directly results in auto parts and components life
The product cycle is long, high cost and the complicated operation of multistep are caused percent defective rising, poor product quality.
For case above, this case proposes a kind of production method of auto parts and components, complicated technology is simplified, and avoid
The making processing of many set complicated dies, shortens the production cycle, reduces production cost, improves lumber recovery and product performance.
The content of the invention
A kind of auto parts and components production method, wherein auto parts and components production method includes：
Laser blanking：By raw material sawing it is appropriate size, shape using laser cutting machine.Laser cutting has efficiency
High, sheet deformation amount is small, without tool wear, noise is small, cutting material species is more, cutting route change is flexible the advantages of.
Drawing die N one-step formings：The position of stretching is needed to walk drawing and forming by N blank with drawing die, N is >=1
Natural number.Drawing die makes simple, cycle is short, low cost, and can be according to the characteristic of different materials, part stretcher strain amount
Deng flexibly change N values, and mould is equally applicable in the case that parts locally size occurs small change.Conversely, also dependent on
The stretching die cavity of mould is flexibly changed in the change of parts locally size.
Cutting：The semicircle cutting removal of the convex born of the same parents end after by stretching.
Simple die returns pier：The convex born of the same parents part after semicircle will be cut off to carry out upset in pier mould is returned, and makes stretching position
Highly diminish, wall thickness increases, this process is also the process for changing stretching position mechanics performance.
Cutting hole and side：Cut out the hole on part, remove unnecessary side.
Simple forming mould compression molding：The workpiece that will process part shape using simple forming mould puts mould into
Final molding in tool, easy mould makes simple, and cycle is short low cost, modification is flexible, for the automobile for needing bending
Part fixed effect is preferable and conveniently holds bending angle, can be held well for bending angle, produces in batches.
In auto parts and components production method, it is preferred that the laser blanking step is included on raw material and sets under flat board
Stockline, one or more location holes；Setting flat board lower stockline can reduce the generation of waste material, set location hole lifting cutting process
Accuracy, security, reduce blanking cutting there is the probability of waste material.
In auto parts and components production method, it is preferred that the multi-step tension shaping is all complete in same drawing die
Into.Heating for multiple times, repeatedly more mold exchange are avoided in multi-step tension shaping, is shortened the production cycle and is reduced energy waste；One mould
The drawing die of multi-cavity can not only produce different drawn products, and the identical products different for material plasticity are needed according to material
When increasing or decreasing stretching step time, can still be operated in same drawing die, without re-working mould.
In auto parts and components production method, it is preferred that cut using grinding machine in the end semicircle step of the convex born of the same parents of cutting
Cut or sander hand sand, it is necessary to produce in batches, cut half circular diameter it is big when can be cut using grinding machine, produce as a trial first, cut
Benefit, to reduce production cost, can be realized using sander hand sand when cutting small diameter or less output.
In auto parts and components production method, it is preferred that described time pier step is provided with one or more time pier in special
Returning in pier mould or returning for die cavity is completed in the shared multifunctional mold of pier, multi-step tension.The situation that mold work space meets
Under, can will return pier die cavity and be arranged in same mould with multi-step tension die cavity, so can both save mold design, processing
Cost, can remove heating, the energy of more mold exchange and time repeatedly from again, further reduce production cost, accelerate manufacturing schedule；
When conditions above is unsatisfactory for, pier particular manufacturing craft can be also made back.Certain Special back pier mould and share back pier, drawing die
Returning pier die cavity can have multiple, and pier is returned with the multistep for returning pier or identical product for meeting different product.
In auto parts and components production method, it is preferred that the special time pier mould also sets in addition to die cavity in time pier mould
There is die cavity in the mould close with final simple forming mould.For the parts of final difficult shaping, can be set in pier mould is returned
The die cavity close with final simple forming mould is put, makes part during Hui Dun while being carried out to other hardly possible shaping positions pre-
Shaping, is that last simple forming mould compression molding is laid the groundwork, the appearance profile of more preferable retaining element, improves lumber recovery,
Simultaneously because need to be molded position has reached the use combination property for more optimizing by repeatedly deformation.
In auto parts and components production method, it is preferred that using two dimension or three-dimensional laser in the cutting hole and side step
Cutting.Laser cutting route changes flexible, and efficiency high, heat affecting is small, and sheet deformation amount is small, and without tool wear, noise is small, cutting
Material category is more.For shape close to plane, cutting route it is simple when using Two Dimension Laser-Cutting can meet require；For shape
Shape structure, cutting route complicated three-dimensional parts or dimension precision requirement important spare part higher, can use three-dimensional laser
Cutting, improves cutting accuracy and efficiency.
In auto parts and components production method, it is preferred that stop one after mould closure during the final compression molding
Divide mould again after the section time.Die sinking immediately can cause that elastic part occurs in the big position of resistance of deformation occurs after mould closure
Elastic recovery, the final profile size of part deviates requirement, and a period of time of pressurizeing is continued after mould mold closing, can reduce elasticity time
It is multiple, preferably part is shaped, prevent material from the retraction produced after elastic deformation occurring.
In auto parts and components production method, it is preferred that the drawing die and the simple forming mould of final compression molding
Tool is all disposably completed by CNC milling machine, linear cutter, returns that pier mould is cut using CNC milling machine, line, numerically controlled lathe coordinates
Complete.
In auto parts and components production method, it is preferred that 1 or many is provided with the mould used in the production method
Individual liftout attachment.Deeper for part stretching die cavity, the larger parts of skin-friction force occur difficulty after being molded in a mold
With the phenomenon of the demoulding, the extension of production cycle can be caused or after demoulding so that material deformation is scrapped, so according to part shape
The features such as size can be in a mold in mold design appropriate location one or more liftout attachments are set, it is ensured that in mould
The workpiece of shaping can the smoothly demoulding.
