Product Description JinJiang Stable Technical MFG Co.Ltd was a company which focus on the cold forming by press and stamping production process.The stamping metal part can apply to a lot of area ,such as motor part as mounting bracket ,starter bracket ,oil pump bracket ,water pump bracket ,Alternator Mounting Bracket , Muffler Exhaust Mounting Bracket,Starter Brace Bracket,Motor Mount Engine Bracket etc ....All the metal stamping part was made by the stamping ,pressing ,press brake ,laser cutting machine ,polishing machine .Let`s start the journey of metal stamping part within JinJiang Stable Technical MFG Co.Ltd 1.Raw material steel sheet coil incoming testWe would like to show you step by step about how the stamping metal bracket such as Brake pedal,Accelerator pedal,Cylinder Block Stiffener Plate being produced in our company Every single of metal bracket was made by steel sheet plate,So the first step of the production was the raw material inspection ,we do the inspection of Brake pedal,Accelerator pedal steel sheet plate by chemical composition,Mechanical properties,Every steel sheet had its Tensile strength, yield strength, elongation,every different of the coil had different Mechanical properties,The key of the press deep drawing for the Brake pedal,Accelerator pedal was the elongation,we always use the raw material with elongation over 25%,Hereby in China we called this type of raw material as DC06.2.Decoiling for the steel coilThe raw material steel sheet was bring into warehouse by the coil ,to make the transport for raw material much more convenience,the steel company always use steel coil shipped to the customer with Material certificate.So when we got the raw material from steel company ,the first thing was testing and the next step was decoiling for the steel coil.Material certificate and unloading the steel coil at the warehouse3.Stamping workshop for starter bracket,oil pump ,water pump metal bracket Brake pedal,Accelerator pedal drawing Normally the metal steel stamping part start by the laser cutting machine ,but we perfect to show you how what was the stamping punghing production process first The key of the stamping metal part was also use the stamping dies mold install on the stamping punching machine ,then we put the raw material inside the die use the location pin or place on the dies.So anyway we need the die for the metal steel stamping part let me show some of the part we make before Engine oil pan oil level sensor bracket ,Steering bar ,Car undercarriage beam ,Oil filter ,Engine block support plateTO MAKE THE STAMPING STEEL BRACKET DUST COVER AND UNDERCARRIAGE CORSS BEAM IT WAS SIMILAR LIKE THE ENGINE OIL PAN 4.Engine oil sump Stamping mold production Setup- get data from the steel stampin oil sumpWhen we got a project for a rear engine oil sump for truck or for car ,the first step was set up a project team ,we call it as APQP ,Stable Technical MFG always follow the TS 16949 ,IATF 16949 is an international standard for automotive management systems that is a widely adopted and standardized quality management system.The core team typically consists of representatives from different functions, such as engineering, quality, manufacturing, purchasing, sales, and customer service.The key functions for engineering was design the drawing for oil pan ,then the mold ,how to make it ,how to control the tolerance.To get the data from the engine oil sump ,there was two way ,the most easy one was by 3D scanning ,we take the equipment from creamform (Portable, metrology-grade 3D scanners accuracy, resolution, reliability and fast data acquisition). 4.1 Stamping press mold design After we got the data from the scanner by stl format we will import it into the Design X ,Solidwork ,UG ,transfer it to 3D mold.Then we get the 2D drawing for production .The 2D drawing was contain the size ,shape ,tolerance ,raw material inside and we sent to the customer for approved 4.2 The simulation of the oil pan deep drawing production process To get the stp file input for simulation ,there were two ways:1.get the 2D file from customer ,2,reverse the engineering .After the engine oil sump mold was completed design ,we need to go though the simulation for the engine oil pan as deep drawing production process.We save the 3D from the UG and output as stp file ,then we input the stp file into the just stamping simulation software to review if the pan was crack during the drawing processThe purpose of the simulation was short the leadtime for development and save the cost for customer when design the oil pan or oil sumpThe red area of the simulation result as above for the engine oil pan was there was a big chance to crack ,the blue area mean the oil pan will be short of raw material ,so when we can decide the blanking size for the oil pan before we input the real production 4.3 Oil pan deep drawing mold production by casting and CNC machine The first step to production the engine oil pan mold was the casting production process ,normally it was by the sand casting for the mold frame and support ,usually a stamping mold was combine by two part ,core steel mold for the shap of the oil pan and the frame to support on the press stamping machine To get the core for the rear oil sump we take the fast way by the CNC machine then go ahead with the polishing process by hand so that surface of the mold didnot make too much scratch of the truck oil sump ,then we assemble the core and the frame together to go ahead with trail production of the oil pan sample .4.3 CMM inspectionfor the critical dimension of the pan Whatever is the inspection gauge or the oil pan mold we need to go though the CMM inspection before we put into production The critical dimension need to go though the CMM test to get the tolerance for the oil pan mold we design Every oil pan had tolerance ,the best way to keep the tolerance as much more strictly than the drawing call out ,so once the steel spring back it was still under the tolerance requirement .For the first sample of the oil pan we also need it to go thought by CMM for all the bolts holes.then we get the inspection report to save for the future use It was a procedure require by quality control system 16949.5. Trial production for engine oil pan The reason why we need to go though trail production was to test the mold if it can go though well production .To check all the critical dimension under the control,to get the oil pan so that we can go though test by CMM for the engine oil pan bolts holes and leaking test .The workshop for drawing press stamping the engine oil pan The oil pan need a lot of space to save for storage .So we use a lot of steel frame crate to storage the engine oil pan and oil sump for truck and carMost of the oil pan and oil sump need about 5 production process for the stamping and pressing ,so we need a lot of space to made the transfer during different production process.6. Welding for the reinforcement and baffleThere were two kinds of the place for engine oil pan need to be apply for the spot welding :baffle and reinforcement ,because baffle just need to attach on the oil pan without too much strength so we use the spot welidng insted of the shield welding Most of the engine oil pan had the baffle and some kinds of the engine oil sump need reinforcement To made them attch on the oil pan ,the shield welding was not the best choice so we adopt the spot welding machine ,some of them called it as resistance welding.The reason why we used the robot spot welding machine for the oil sump was because we didnot need to turn the oil pan up and down to do the resistance welding for baffle and reinforcement.6. Shield welding for the extra package of the oil pan Some of the engine block need more lubrication oil because it need high horsepower performed,so they may need extra lubrication oil to storage inside the oil pan .Some of the engine block due to the space limit and need to make it as different type so we cant make the press drawing once a time it also need the extra package .To make the main oil pan and the storage oil package well attachment as one piece so we need to use shield welding also some of us called it as CO2 welding .The most advantage of the shield welding was it can seal from the oil to leak outside.The shield welding was the main reason why we need to do the leaking test after all production process was done and before the surfacement such as like the power coating or ElectrophoresisThe stamping part on the press machine and stamping punching machine The shield welding machine for cross beam after assemble on the welding gaugeWhen we want to welding a lot of part together It was much more convenience to use the welding robot plus the welding fixture .It was similar like the fool-proof incase lead the quality issue by missing the welding or the welding to wrong place ,so we use the welding robot to improve the PPM for our customer.
