Description
Technical field
The present invention relates to knuckle manufacturing technology field, more particularly to a kind of steering knuckle forging round steel flexibility blankers
Skill.
Background technology
Round steel is a kind of common forging quality steel material, such as a variety of auto-parts of spindle, steering arm.Forging includes
Open type forging, closed-die forging, by taking knuckle as an example, are forged using open type in the prior art, since overlap is more, stock utilization
Generally 85%~88%, using closed-die forging, stock utilization can generally be increased to 95%, even higher.But it is producing
It is found in practice, either open type forging or closed-die forging, if carrying out blanking, meeting according to forged material utilization rate theoretical value
Product fraction defective is caused to be promoted, i.e. portioned product fills that type is not full, and forging is defective, leads to product rejection, is asked to solve this
Topic, can generally increase the cutting length of forging, and expand mold cavity volume in production practices, although solving product, to fill type not full
The problem of, but stock utilization is reduction of, and increase the workload of following process.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to and provide a kind of steering knuckle forging round steel flexibility blankers
Skill, by flexible blanking, adverse effect caused by reducing round steel diameter fluctuation improves stock utilization, after reducing
The workload of continuous processing.
The technical solution adopted by the present invention to solve the technical problems is：A kind of steering knuckle forging round steel flexibility blankers
Skill, the quality for measuring knuckle finished product are M, the quality N of round steel bar according to needed for calculating forged material utilization rate theoretical value,
The volume V of round steel bar according to needed for calculating the density of round steel bar, then using sawing machine blanking, during blanking, with round steel to
Preceding movement measures the diameter of several positions of round steel along its length, length when billet quality is calculated as N, according to this
The 100.8%~102% of length carries out blanking.
Preferably, when measuring the diameter of round steel, the continuous diameter for measuring round steel or the diameter every 2cm measurement round steel.
Preferably, two groups are measured during the diameter for measuring round steel, second group of measurement angle is rotated for first group of measurement angle
90°。
Preferably, the quality of bar is detected after blanking, removal quality is less than the bar of N × 100.5%.
The beneficial effects of the invention are as follows：A kind of steering knuckle forging round steel flexibility technology for blanking, measure first knuckle into
The quality of product is M, the quality N of round steel bar according to needed for calculating forged material utilization rate theoretical value, according to the close of round steel bar
Degree calculate needed for round steel bar volume V, then using sawing machine blanking, during blanking, as round steel moves forward, along its length
The diameter of several positions of round steel is measured, length when billet quality is calculated as N, according to the 100.8%~102% of the length
Blanking is carried out, avoids in the prior art according to regular length blanking, causes part bar former due to the fluctuation of round steel diameter
Material is insufficient generation substandard products, for the present invention according to the diameter change flexibility blanking of round steel, it is unfavorable caused by round steel diameter fluctuation to reduce
It influences, so as to reserved less allowance, reduces waste of material, improve stock utilization, reduce follow-up add
The workload of work.
Specific embodiment
With reference to specific embodiment, the present invention is described in further detail, is not the practical range the present invention
Limited to this.
The steering knuckle forging round steel flexibility technology for blanking of the present embodiment, the quality for measuring knuckle finished product first are M, according to
The quality N of round steel bar needed for the calculating of forged material utilization rate theoretical value.Quality N is the benchmark that blanking of the present invention determines size,
Here forged material utilization rate theoretical value refers to, according to technical conditions and level of processing, is removed in forging machining process
Amount of metal is minimum, forging when flash it is minimum in the case of stock utilization.Then according to needed for calculating the density of round steel bar
The volume V of round steel bar, then using sawing machine blanking, during blanking, as round steel moves forward, if measuring round steel along its length
The diameter of dry position, length when billet quality is calculated as N carry out blanking according to the 100.8%~102% of the length,
It avoids in the prior art according to regular length blanking, part bar insufficient raw material generation is caused due to the fluctuation of round steel diameter
Substandard products, the diameter change flexibility blanking of the invention according to round steel reduce adverse effect caused by round steel diameter fluctuation, so as to
With reserved less allowance, reduce waste of material, improve stock utilization, reduce the workload of following process.
By taking the round steel of a diameter of 110mm as an example, according to national standard GB702-86, diameter deviation that round steel diameter allows for ±
1.2mm, deviation are more than 1%, when the raw material of buying meet the standard, lead to weight due to the fluctuation of diameter（Or volume）It is inclined
Difference can exceed that 2%, to overcome the deviation, will seriously affect the workload of stock utilization, yields, following process.
Process according to the invention, the error of quality of materials can be controlled within 1% during knuckle blanking, forging process
Middle stock utilization can reach 98.5%, and yields reaches 99%, be greatly improved compared to 95% before.
Further, when measuring the diameter of round steel, the continuous diameter for measuring round steel or the diameter every 2cm measurement round steel.
Further, two groups are measured during the diameter for measuring round steel, second group of measurement angle is revolved for first group of measurement angle
Turn 90 °, so as to more accurately measure the variation of round steel diameter, using two groups of data as the foundation of calculating sectional area after average.
Further, the quality of bar is detected after blanking, removal quality is less than the bar of N × 100.5%, in screening out
The defective bar in portion.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than the present invention is protected
The limitation of range is protected, although being explained in detail with reference to preferred embodiment to the present invention, those of ordinary skill in the art should
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
