The content of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of Novel sheet metal part manufacturing process, the flow process is designed the blank dimension of vehicle right and left wind scooper sheet metal component, and on the premise of quality is not affected stock utilization is improved；Correspondence calculating is carried out to mold work parameter and device parameter, it is ensured that reasonable employment, it is to avoid cause energy waste；The layout of working site is adjusted, as far as possible can continuous productive process improving efficiency；The problems such as to stamping procedure by technological demonstration, the merging of sequencing and operation for operation, is adjusted or improves；It is adjusted to welding technique process, to reach energy-saving purpose；Greasy dirt, the corrosion produced during to work pieces process is processed leftover pieces from basic solution, is reached and is made the best use of everything.
The technical scheme is that：A kind of Novel sheet metal part manufacturing process, the technological process is related to the manufacturing process of vehicle right and left wind scooper sheet metal component and flow process, including following manufacturing process：
Operation 1, plate shearing machine for blanking；
Operation 2, mould scale material cuts punching；
Operation 3, mould molding；
Operation 4, mould bending；
Operation 5, mould separates punching；
Operation 6, butt resistance welding；
Operation 7, pickling, phosphatization；
Operation 8, electrostatic spraying；
Operation 9, entrucking warehouse-in.
To operation 1, the tolerance constraints of blank size are：± 0.25mm, the dwell time scope of operation 3 is：7-9 hours.
The vehicle right and left wind scooper sheet metal component of operation 8 is provided with aperture and corresponding bolt, and the diameter of the aperture control bolt of vehicle right and left wind scooper sheet metal component is adjusted in the margin of tolerance；Make bolt and aperture constrained each other, monolateral gap is between 0.05mm-0.1mm.
Existing process flow process operation is excessive；Utilization rate of equipment and installations is low；Inefficiency；Up and down procedure connection is not careful enough；
There is the operation erasing manual operation such as greasy dirt and clear welding slag, productive temp is uncoordinated to realizing continuous productive process.Leftover pieces are rationally utilized.Modifications and adaptations have been carried out to original technological process with deficiency for disadvantage mentioned above.Technological process after improvement improves material and facility utilization rate；Greatly improve operating efficiency and product percent of pass.Raw material parameter is designed, the equipment in process is designed, manufacturing procedure and technique are designed, reached good effect.
The present invention has the advantages that：
1) present invention greatly enhances material and facility utilization rate, utilization rate of raw materials brings up to 97%.
2）The present invention substantially increases operating efficiency, and whole work efficiency improves 85%.
3）The present invention substantially increases product percent of pass, and product percent of pass has reached 98.7%.
4）The present invention saves 63% in terms of manpower.
Specific embodiment
The present invention is designed for the processing technology of vehicle right and left wind scooper sheet metal component, and on the basis of original significant improvement, including following operation have been carried out：
Operation 1, plate shearing machine for blanking；
Operation 2, mould scale material cuts punching；
Operation 3, mould molding；
Operation 4, mould bending；
Operation 5, mould separates punching；
Operation 6, butt resistance welding；
Operation 7, pickling, phosphatization；
Operation 8, electrostatic spraying；
Operation 9, entrucking warehouse-in.
1）Adjustment and improvement aspect to material
（1）：Tolerance constraints are added to the plate shearing machine for blanking size of operation 1.（±0.25mm）, in the Measurement Allowance of product, Jing tests can reach requirement.
（2）：Because of the raising of the plate shearing machine for blanking dimensional accuracy of operation 1., the processing of mould scale material can be changed to the mould blanking of operation 2.,（Note：Blanking is to remove material method to blank material periphery and internal feature；Scale material is to borrow blank material periphery, only removes material to internal feature, thus can improve stock utilization）.Stock utilization brings up to 97% by original 51% after improvement.（3）：After to the processing of the mould scale material of operation 2., the material of the waste material that inside occurs, material is thick, and peripheral dimensions etc. are counted；In correspondence waste material feature find that vehicle right and left support can be produced.Because vehicle right and left wind scooper and Auto Instrument desk or so support is same automobile model, so material, quantity is unanimously.The material of Auto Instrument desk or so support need not get the raw materials ready after improvement；Material-saving 100%.
2）Adjustment and improvement aspect to equipment
（1）：The original production equipment of mould molding is YZ27-630 presses（Main motor current 44KW/h）；Use YZ27-400 presses（Main motor current 22KW/h）Angle of arrival rebound phenomenon during experiment, later on earth the dwell time produced qualified products to adjusted equipment；Energy saving 80% after adjustment.
（2）：Mould bending operation is original respectively in J31-315 closed single points（Main motor current 30KW/h）Production；Later the stamping press of two molds calculated respectively；Determine two original molds simultaneously in J36-630 closed double-points（Main motor current 55KW/h）Production.(note：J36-630 closed double-point work tops are big).Energy saving 83.3% after adjustment；Improve operating efficiency 88%.
3）Working site is adjusted and is improved
（1）：Originally product turnover employment is pushed and pulled a cart between last process and next procedure, is occurred laborious. and it is time-consuming. product easily overstocks the phenomenons such as deformation；Through the fixation planning to measurement and material area between equipment；The removable product carriage in inclined-plane is built between devices in decision；Solve problem above.Whole work efficiency improves 78.5% after adjustment；Product sequence turnover qualification rate reaches 100%；Substantially continuous productive process is realized.
4：Operation is adjusted and is improved
（1）：Be previously present erasing greasy dirt operation, belong to manual operation, and occur during plant equipment operation collaborative work work tempo it is uncoordinated the problems such as.By carrying out Analysis on Problems to wiping greasy dirt, it is found that greasy dirt prevents mould from occurring to product " scuffing " plus lubricating oil when being mould molding.Qualified products have been produced in the case of non lubricant oil using copper alloy CB-2H materials to the local for mould at scuffing occur by technological demonstration.Greasy dirt is wiped after adjustment can be without having reached the purpose of reduction operation, saving manpower 28%.
（2）In the past clear welding slag was also required to manual operation；Work is also comparatively laborious.Welding slag is positioned by original operation bolt position（Spot welding）Cause.Spot welding is dimensional accuracy between principal security bolt, because the diameter of bolt it is excessive with the bore clearance of product.Finally the diameter that the aperture of product compares bolt is adjusted in the margin of tolerance；Make bolt and aperture constrained each other（Monolateral gap ensures between 0.05mm---0.1mm）.Jing tests size qualification（Product tolerance be ± 0.5mm, actual maximum deviation 0.25mm -0.3mm）.Adjustment rear bolt position positioning（Spot welding）Can also omit with former clear welding slag；Reach reduction operation and saved the purpose of wlding solder flux, save manpower 35%.
After above-mentioned technological process, the present invention saves 63% in terms of manpower, and utilization rate of raw materials brings up to 97%, and whole work efficiency improves 85%, and product percent of pass has brought up to 98.7%, and energy saving increases benefit more than 2,600 ten thousand yuan in year more than 80 percent.
