Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of automotive oil tank end socket lid closing in shaping and punching mould, as shown in Figure 1, comprise counterdie, patrix and movable awl mouthful mould 4, a movable awl mouthful mould 4 is a circulus, a movable awl mouthful mould 4 is positioned in the middle of counterdie and the patrix; Counterdie includes lower bolster 1, is installed with down die-cushion 2 and end opening mould 3 above the lower bolster 1, and end opening mould 3 is a circulus, and following die-cushion 2 is positioned at end opening mould 3, and movable awl mouthful mould 4 is corresponding about in the of 3 with the end opening mould; Patrix includes cope match-plate pattern 13, is installed with closing in backing plate 12 below the cope match-plate pattern 13, is installed with shaped opening mould 11 below the closing in backing plate 12, and shaped opening mould 11, closing in backing plate 12 are corresponding about in the of 4 with movable awl mouthful mould; Connection cushion cover 16 is installed in the middle of the cope match-plate pattern 13, is installed with cylinder 18 above the connection cushion cover 16, the piston-rod lower end of cylinder 18 is installed with conical rod 9, and conical rod 9 lower ends are installed with nose cone 5; Below the connection cushion cover 16 template is installed and connects dish 10; Template connects dish and is installed with dovetail template 8 below 10; Have slide block template 7 on the dovetail template 8; Slidely connect dovetail slide block 6 on the slide block template 7, dovetail slide block 6 is corresponding with nose cone 5, and dovetail slide block 6 is a back taper with the contact-making surface of nose cone 5; Between dovetail template 8 and the cope match-plate pattern 13 spring is installed.Be installed with spring screw mandrel 15 on the said dovetail template 8; Spring screw mandrel 15 passes from said spring; Be installed with spring flange cover 14 on the said cope match-plate pattern 13, the upper end of said spring withstands in the spring flange cover 14, and spring screw mandrel 15 upper ends are passed in the middle of spring flange cover 14.Connecing dish 17 through cylinder above the said connection cushion cover 16 links to each other with said cylinder 18.Be fixedly connected with alignment pin 19 above the said movable awl mouthful mould 4, said movable awl mouthful mould 4 lateral surfaces are fixedly connected with mould 20, and movable awl mouthful mould 4, alignment pin 19 and mould are structure as a whole 20.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
The utility model is the disposable stamping die of automotive oil tank end socket lid closing in, mainly utilizes the shrinkage expansion effect of inner die (being the dovetail slide block), can utilize inner die to reach the effect that closes up and be shaped, and can realize that again workpiece closing in back is conveniently stripped.Specific operation process is: a manual operation activity awl mouthful mould at first, with alignment pin and manipulating cylinder again after the shaped opening mould cooperates, first extrusion workpiece closing in taper dimensions; And then a mouthful mould is bored in activity take away, utilize the shaped opening mould, after inner die extruding expansion; Press down through the piston rod of cylinder and to reach the closing in size; Again inner die is shunk, make the workpiece demoulding after, accomplish the closing in forming process.
The utility model is to be closed up by traditional single circular fuel tank end socket lid lathe rolling to change disposable mould punching press closing in into; The fuel tank end socket lid end face that former punching press is become tubular has increased big R arc; The process mould is improved to step suit end socket lid by tubular end socket lid after carrying out disposable extruding closing in.End socket cup shape external diameter after the improvement is identical with the oil box outside dimension; Closing in step place outside dimension is identical with the oil box internal diameter size; The closing in step part is installed to cooperate with the oil box internal diameter and is formed good location and sealing effectiveness, changes welding then over to, has created good condition to welding sequence.
The basic at present flanging flanging process that adopts of automotive oil tank end socket sealing tech; The circular fuel tank of indivedual minorities adopts rolling techniques make use closing in lathe to close up; Utilize technique for rolling closing in diameter dimension error bigger, great majority did not reach the precision that is sealed and matched when casing and end cap were equipped.Simultaneously, adopt the rotation technique for rolling can only produce circular fuel tank, can not produce D shape, rectangle or special-shaped fuel tank such as square.Use the fuel tank end socket lid of the utility model press forming, its measure of precision has improved than traditional technique for rolling, and end socket lid shaping qualification rate improves more than 20%.Simultaneously traditional lathe closing in technique for rolling can only the circular fuel tank end socket lid of rolling, and the utility model only need change fetal membrane just can suppress successful D shape, rectangle, multiple obform body fuel tank end socket lid such as square.Utilize the utility model that multiple special-shaped fuel tank is improved to by the flanging crimping sealing process of original backwardness and can reach the purpose of automatic solder up after the closing in suit cooperates, thereby make model change, improved the sealing property of fuel tank.
The utility model is different from conventional press forming die, and all the internal diameter size with product is identical because conventional its loose tool diameter dimension of press forming die is general, but the utility model is different; If the design size of inner die is directly identical with the internal diameter size of product; Product just can't be deviate from through the back inner die that closes up, for this reason must the improvement loose tool, and also this loose tool need possess and can shrink and expansible technical functionality; Size after loose tool opens must be identical with the internal diameter size of product; Size after size after loose tool shrinks must close up less than product so just can help loose tool and after punching press, deviate from, otherwise can't reach the purpose of the workpiece demoulding after the punching press.The utility model is divided into 8 equal portions to inner die (being the dovetail slide block); And be provided with advance and retreat slideway (being the slide block template); After utilizing nose cone through the cylinder pressure extruding dovetail slide block is opened, reach closing in internal diameter requirement size, and then utilize spring thrust that the dovetail slide block is shunk; Be less than the size after the closing in, final mould is accomplished in stamped workpieces and loose tool deviate from smoothly after closing up.
After the succeeding in developing of this technology, solved the difficult problem that routine techniques can't close up, its scale error of product workpiece of utilizing this technological punching press has improved product percent of pass less than specification requirement.Simultaneously, this technology has also replaced the rolling technology of single lathe closing in round piece, and the utility model helps the multiple special-shaped fuel tank end socket lid of compacting closing in, helps the various special-shaped fuel tank products of Development and Production.
The utility model is applicable to four column pressure machines, increases
high 400mm thick walled steel tube in the time of fixedly around the cope match-plate pattern as backing plate.
