Operation 3, mould molding;
Operation 4, mould bending;
Operation 5, mould is separated punching;
Operation 6, butt resistance welding;
Operation 7, pickling, phosphatization;
Operation 8, electrostatic spraying;
Operation 9, entrucking is put in storage.
To operation 1, the tolerance constraints of blank size is: ± 0.25mm, and the dwell time scope of operation 3 is: 7-9 hour.
Operation 8 vehicle right and left wind scooper sheet metal component is 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; Allow 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; Upper and lower procedure connection is careful not; There is manual operation such as operation erasing greasy dirt and clear welding slag etc., productive temp is inharmonious to realizing continuous productive process.Appropriate application is not carried out to leftover pieces.With not enough for above shortcoming original technological process is improved and adjusted.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, reach good effect.
The present invention has following beneficial effect:
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 manpower.
Detailed description of the invention
The processing technology that the present invention is directed to vehicle right and left wind scooper sheet metal component designs, and significant improvement has been carried out on original basis, comprises following operation:
Operation 1, plate shearing machine for blanking;
Operation 2, punching cut by mould scale material;
Operation 3, mould molding;
Operation 4, mould bending;
Operation 5, mould is separated punching;
Operation 6, butt resistance welding;
Operation 7, pickling, phosphatization;
Operation 8, electrostatic spraying;
Operation 9, entrucking is put in storage.
1) to adjustment and the improvement aspect of material
(1): tolerance constraints (± 0.25mm) is added to operation 1. plate shearing machine for blanking size, in the Measurement Allowance of product, can requirement be reached after tested.
(2): because of the raising of operation 1. plate shearing machine for blanking dimensional accuracy, the processing of mould scale material can be changed into operation 2. mould blanking, (note: blanking removes material method to blank material periphery and internal feature; Blank material periphery used by scale material, only removes material to internal feature, thus can improve stock utilization).After improving, stock utilization brings up to 97% by original 51%.(3): after the processing of operation 2. mould scale material, the material of the inner waste material occurred, expect thick, peripheral dimensions etc. are added up; Find when corresponding waste material feature to produce vehicle right and left support.Because vehicle right and left wind scooper and Auto Instrument desk left and right support are same automobile model, so material, quantity is unanimously.After improving, the material of Auto Instrument desk left and right support does not need to get the raw materials ready; Save material 100%.
2) to 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), through adjustment equipment, the dwell time produced qualified products on earth afterwards; Economize energy 80% after adjustment.
(2): mould bending operation was produced at J31-315 closed single point (main motor current 30KW/h) originally respectively; Respectively the stamping press of two molds was calculated afterwards; Determine two original molds to produce at J36-630 closed double-point (main motor current 55KW/h) simultaneously.(note: J36-630 closed double-point work top is large).Economize energy 83.3% after adjustment; Increase work efficiency 88%.
3) to working site adjustment and improvement
(1): originally between last process and next procedure, product turnover employment is tried hard to recommend and pulled a cart, and occurs effort. time-consuming. product easily overstocks the phenomenons such as distortion; Through the fixation planning to measurement and material district between equipment; Determine to build the removable product carriage in inclined-plane between devices; Solve above problem.After adjustment, whole work efficiency improves 78.5%; Product sequence turnover qualification rate reaches 100%; Substantially continuous productive process is achieved.
4: to operation adjustment and improvement
: there is in the past erasing greasy dirt operation, and belonged to manual operation, and during the collaborative work of plant equipment operation, occur the problems such as work tempo is inharmonious (1).By carrying out Analysis on Problems to erasing greasy dirt, when finding that greasy dirt is mould molding, prevent mould from occurring product " scuffing " apply oil.By technological demonstration to occurring that the local of scuffing place mould adopts copper alloy CB-2H material, under unlubricated oil condition, qualified products are produced.Adjustment after erasing greasy dirt can, reach reduction operation object, save manpower 28%.
(2) clear welding slag also needs manual operation in the past; Work also more loaded down with trivial details.Welding slag locates (spot welding) by original operation bolt position to cause.Spot welding is dimensional accuracy between principal security bolt, because the bore clearance of the diameter of bolt and product is excessive.Finally the diameter of the aperture of product contrast bolt is adjusted in the margin of tolerance; Allow bolt and aperture (monolateral gap ensure 0.05mm---0.1mm between) constrained each other.Through experiment size qualification (product tolerance is ± 0.5mm, actual maximum deviation 0.25mm-0.3mm).After adjustment, bolt position location (spot welding) and former clear welding slag also can omit; Reach the object of reduction operation and saving wlding solder flux, save manpower 35%.
After adopting above-mentioned technological process, the present invention saves 63% in 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 economize energy, more than 80 percent, increases benefit more than 2,600 ten thousand yuan year.
