Embodiment nine:
The present embodiment is a kind of thread rolling method using above-mentioned thread rolling machine.
Thread rolling processing is a kind of supermatic super large batch mass production method.Due to being a large amount of production of super large batch,
Therefore, it is desirable to which artificial interference production process can be reduced to the greatest extent, automation is realized as far as possible in other words.Automated production not only needs certainly
The processing of dynamicization, it is also necessary to the detection of automation, to guarantee the quality of product.Thread rolling processing, which is that a kind of consistency is extraordinary, to be added
Work mode can generally guarantee processing quality.Although the consistency of thread rolling production is good, it also will appear some special feelings
Condition causes the appearance of defect ware.Such as: workpiece enters processing stations (causing random tooth), has special-shaped workpiece mixed with incorrect
Enter (diameter increases or reduces), two workpiece while entering processing stations (feeding unit malfunction), workpiece material itself not
Uniformly etc., it can all generate workpiece quality variation unexpected in process.In these emergency events, if screw plate not by
Injury, then processing can also continue, if screw plate is destroyed, it is necessary to shutdown maintenance.There are also a kind of most commonly seen feelings
Condition is abrasion of the screw plate after long-play, needs replacing screw plate.But it is needed replacing when how long is operation, this is completely
By sampling Detection and experience.For a long time, no effective on-line checking mode is processed in thread rolling, can not be in process
In each workpiece is detected at any time, to reach the boundary of complete quality control.The reason of generating this situation has two: first is that
Since the process time that single workpiece is processed in thread rolling is too short, general only zero point several seconds, however, the detection to screw thread, even
Most fast artificial visual detection, also at least needs several seconds time.From detection time, each workpiece is examined online
It surveys almost impossible.Second is that thread measurement is a kind of relative complex detection process, detection screw thread is needed using a variety of different
How instrument carries out quick on-line checking, and which type of detection mode to carry out on-line checking using, is all in the industry
Problem.Existing mode can only inspect more demanding product by random samples, i.e., carry out sample evaluation to the product of a batch, obtain
The quality evaluation of only this collection of product arrived.This detection mode produces the good processing method of this consistency to thread rolling, also
It is good, it is generally also helpless but if there is individual substandard products in batch.In view of this how to be carried out during thread rolling
Line detects automatically, is a very difficult problem, the method that do not cope in the industry for many years to control the quality of thread rolling.
Even now in the spring tide of electromechanical, also without proposing effective method.
The present embodiment is a kind of thread rolling online test method.The basic ideas of the method are: being examined using pressure sensor
Thread rolling pressure is surveyed, pressure anomaly occurs and then alerts or shut down.Or the degree of wear of screw plate is judged by detecting pressure change,
To replace screw plate in due course.
The present embodiment takes full advantage of the good advantage of thread rolling production process consistency, and detection screw plate is suffered by the process
The pressure arrived illustrates that production process is normal if pressure is uniform, changes in case of pressure anomaly, then is warned by shutting down
It accuses, so that operative employee tests and repairs.Pressure detecting is very common detection means, display and record pressure data,
And it is all very mature control mode that control, which is shut down,.The utility model utilizes these mature technologies, cleverly applies and is rubbing with the hands
In yarn quality control, solve the problems, such as on-line checking in thread rolling production, being controlled damage, at the same to
When, in what situations replacement screw plate have specific index, i.e. pressure index, make replace screw plate have more section
Foundation.More ironically, by this pressure detecting, the batch work generated because replacing screw plate can also be controlled
The quality difference problem of part, this be also it is long-term in industry since insurmountable problem.
Specific step is as follows for the method:
(1) the step of installation and adjustment screw plate: fixed screw plate is inserted into the translot of vertical adjusting bracket, passes through translot tune
The lateral position of screw plate is determined in solidating, while the vertical position of screw plate is adjusted by dovetail wedge and dovetail groove, makes fixed thread rolling
The position cooperation of plate and sliding screw plate, twists out qualified workpiece.
(2) the step of preprocessing: vertical clamping screw is adjusted, makes pressure sensor by pretightning force.Use a collection of material
Uniform workpiece carries out thread rolling processing, adjusts thread rolling machine and screw plate reaches quality standards, what record each reached quality standards
The pressure value of workpiece in process, and calculate pressure mean value.
When the use of perpendicular wedge and vertical slot being dovetail wedge and dovetail groove, then the clamping screw of dovetail groove can be directly adjusted, is utilized
The tilt angle of dovetail realizes uniform pretightning force, makes pressure sensor in the state of no tonnage, and also output is certain
Pressure value, ambient noise can be eliminated with this, improve measurement accuracy and quality.
Preprocessing in this step, can also be without, and is directly entered process.The purpose of preprocessing is to machine
The understanding of the state of bed itself and screw plate carries out the pressure during thread rolling in the case where same thread rolling machine and screw plate
The detection of force value accumulates data, realizes precise measurement or artificial intelligent measuring.
(3) the step of setting pressure limit: the upper and lower bound of variation range above and below setting pressure mean value adds as normal
The foundation of work.
The setting of range of pressure values, the setting of threshold value is extremely important in other words, should reach the purpose of control quality, again
Prevent erroneous judgement, therefore, when control pressurer system is relatively simple, can should be larger with threshold range, if it is artificial intelligence
It can be then arranged using multiple threshold values when judgement, this processing situation is judged and provides different processing.
(4): there is pressure anomaly suddenly in process in the step of processing, is more than upper pressure limit or lower limit, illustrates
Now processing is abnormal then to shut down.Or after processing operation after a period of time, pressure is gradually decrease to low pressure limit, illustrates screw plate
Abrasion is then shut down.
In thread rolling processing, it is simply direct shutdown that exception, which occurs, in the pressure value that screw plate is subject to a variety of to be handled,
It is more slightly more complex, the workpiece of pressure anomaly is separately exported and alarmed, if subsequent workpiece is all pressure anomaly, just
It shuts down and maintains to alert.Increasingly complex, multiple pressure value threshold values can be used, various pressure conditions are located respectively
Reason illustrates processing exception occur if pressure is reduced or increased suddenly, if pressure is gradually reduced, illustrates that screw plate is worn, when
Screw plate will be replaced after reaching a certain level.
If judged using database and artificial intelligence, more complicated control, such as pressure change can be carried out
Curve, pressure value size carry out workpiece, material of various models etc. and carry out judgement and different processing.
Embodiment ten:
The present embodiment is the improvement of embodiment nine, is the refinement for the step of embodiment nine is about processing.Described in the present embodiment
Processing the step of in, pressure be more than the upper limit or lower limit when, the part of pressure anomaly is separated, while alerting and continuing under processing
One workpiece is shut down if pressure continues exception, continues machine process if pressure anomaly disappears, but retain alarm.
Occur pressure anomaly suddenly in process, is more than upper pressure limit or lower limit, illustrates that processing exception occur then stops
Machine, or the abnormal workpiece of processing is separately exported and alarmed, but continues process, if subsequent tonnage value
Recovery normally then continues to process, but if cannot restore normal, then needs to shut down and alert.
It is that after processing operation after a period of time, pressure is gradually decrease to low pressure limit there are also a kind of situation, illustrates thread rolling
Plate abrasion, which is then shut down, is maintained or replaced screw plate.
Finally it should be noted that being merely intended for describing the technical solutions of the present application, but not for limiting the present application above, although referring to compared with
The utility model is described in detail in good arrangement, those skilled in the art should understand that, it can be to this reality
With novel technical solution (such as the citation form and mounting means of the citation form of thread rolling machine, screw plate, step it is successive suitable
Sequence etc.) it is modified or replaced equivalently, without departing from the spirit and scope of the technical scheme of the present invention.
