The present invention has overcome the deficiencies in the prior art, has proposed a kind of vehicle right and left wind scooper sheet metal component manufacturing process flow, and this flow process designs the blank dimension of vehicle right and left wind scooper sheet metal component, improves stock utilization under the prerequisite that does not influence quality; Mold work parameter and device parameter are carried out correspondence calculating, guarantee rationally to use, avoid causing energy waste; Layout to the working site is adjusted, and the energy continuous productive process is to raise the efficiency as far as possible; Stamping procedure by technological demonstration, is adjusted or improved at the sequencing of operation and the problems such as merging of operation; The welding technique process is adjusted, to reach energy-saving and cost-reducing purpose; Workpiece is added the greasy dirt that produces man-hour, corrosion from basic solution, leftover pieces are handled, reach and make the best use of everything.
Technical scheme of the present invention is: a kind of vehicle right and left wind scooper sheet metal component manufacturing process flow, and described technological process relates to the manufacturing process and the flow process of vehicle right and left wind scooper sheet metal component, comprises following manufacturing process:
Operation 1, the plate shearing machine blanking;
Operation 2, mould scale material is cut and is dashed;
Operation 3, mould molding;
Operation 4, the mould bending;
Operation 5, the mold separation punching;
Operation 6, butt resistance welding;
Operation 7, pickling, phosphatization;
Operation 8, electrostatic spraying;
Operation 9, the entrucking warehouse-in.
To operation 1, the tolerance of blank size is constrained to: ± 0.25mm, the dwell time scope of operation 3 is: 7-9 hour.
Operation 8 vehicle right and left wind scooper sheet metal components are provided with aperture and corresponding bolt, and the diameter of the aperture contrast 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 technological process operation is too much; Utilization rate of equipment and installations is low; Inefficiency; Procedure connection is careful inadequately up and down; Exist operation to wipe manual operations such as greasy dirt and clear welding slag, productive temp is inharmonious to realizing continuous productive process.Leftover pieces are rationally utilized.Original technological process is improved and adjusts with not enough at above shortcoming.Technological process after the improvement has improved the material and facility utilization rate; Operating efficiency and product percent of pass have greatly been improved.The raw material parameter is designed, the equipment in the process is designed, manufacturing procedure and technology are designed, reached good effect.
The present invention has following beneficial effect:
1) the present invention has greatly improved the material and facility utilization rate, and utilization rate of raw materials brings up to 97%.
2) the present invention has improved operating efficiency greatly, and whole work efficiency improves 85%.
3) the present invention has improved product percent of pass greatly, and product percent of pass has reached 98.7%.
4) the present invention saves 63% aspect manpower.
The specific embodiment
The processing technology that the present invention is directed to vehicle right and left wind scooper sheet metal component designs, and has carried out significant improvement on original basis, comprises following operation:
Operation 1, the plate shearing machine blanking;
Operation 2, mould scale material is cut and is dashed;
Operation 3, mould molding;
Operation 4, the mould bending;
Operation 5, the mold separation punching;
Operation 6, butt resistance welding;
Operation 7, pickling, phosphatization;
Operation 8, electrostatic spraying;
Operation 9, the entrucking warehouse-in.
1) to the adjustment and the improvement aspect of material
(1): to operation 1. plate shearing machine blank sizes add the tolerance constraint (± 0.25mm), in the Measurement Allowance of product, can reach requirement after tested.
(2): because of the raising of operation 1. plate shearing machine blank size precision, can change the processing of mould scale material into to operation 2. mould blankings, (annotate: blanking is that blank material periphery and internal feature are removed the material method; The scale material is to use blank material periphery, only internal feature is removed material, thereby can improve stock utilization).Improve the back stock utilization and bring up to 97% by original 51%.(3): to after the operation 2. mould scale material processing, the material of the inner waste material that occurs is expected thickly, and peripheral dimensions etc. are added up; When corresponding waste material feature, find to produce the vehicle right and left support.Because of vehicle right and left wind scooper and Auto Instrument desk left and right sides support are same automobile model, so material, quantity is unanimity.The material that improves the Auto Instrument desk left and right sides, back support does not need to get the raw materials ready; Save material 100%.
2) to the adjustment and the improvement aspect of equipment
(1): the original production equipment of mould molding is YZ27-630 press (main motor current 44KW/h); Angle of arrival rebound phenomenon when testing with YZ27-400 press (main motor current 22KW/h), the dwell time was produced qualified products on earth through adjustment equipment afterwards; Adjust back energy savings 80%.
(2): mould bending operation was produced at J31-315 enclosed single-point (main motor current 30KW/h) respectively originally; Respectively the stamping press of two molds was calculated afterwards; Decision is produced two original molds simultaneously at J36-630 enclosed two point (main motor current 55KW/h).(annotate: J36-630 enclosed two point work top is big).Adjust back energy savings 83.3%; Increase work efficiency 88%.
3) working site is adjusted and improved
(1): originally product turnover personnel selection is tried hard to recommend and is pulled a cart the appearance effort between last process and the next procedure. and time-consuming. product easily overstocks phenomenons such as distortion; Through fixation planning to measurement and material district between the equipment; The removable product carriage in inclined-plane is built in decision between equipment; Solved above problem.Adjust the back whole work efficiency and improve 78.5%; Product sequence turnover qualification rate reaches 100%; Substantially realized continuous productive process.
4: to operation adjustment and improvement
(1): existed in the past and wipe the greasy dirt operation, and occurred problems such as work tempo is inharmonious when belonging to manual operation and the collaborative work of plant equipment operation.By carrying out the problem analysis, find to prevent that mould from occurring product " scuffing " apply oil when greasy dirt is mould molding to wiping greasy dirt.By technological demonstration copper alloy CB-2H material is adopted in the part that scuffing place mould occurs, under unlubricated oil condition, produced qualified products.Wipe after the adjustment greasy dirt can, reached the purpose of reduction operation, save manpower 28%.
(2) clear welding slag also needs manual operation before; It is also more loaded down with trivial details to work.Welding slag is to be caused by original operation bolt position location (spot welding).Spot welding is dimensional accuracy between the principal security bolt, because of the bore clearance of the diameter of bolt and product excessive.At last the diameter of the aperture of product contrast bolt is adjusted in the margin of tolerance; Allow bolt and aperture (monolateral gap guarantee 0.05mm---0.1mm between) constrained each other.Through experiment size qualified (the product tolerance is ± 0.5mm actual maximum deviation 0.25mm-0.3mm).Adjusting bolt position location, back (spot welding) and former clear welding slag also can omit; The purpose that has reached the reduction operation and saved the wlding solder flux is saved manpower 35%.
After adopting above-mentioned technological process, the present invention saves 63% aspect manpower, and utilization rate of raw materials brings up to 97%, whole work efficiency improves 85%, product percent of pass has brought up to 98.7%, and energy savings is more than 80 percent, and year increases benefit more than 2,600 ten thousand yuan.
