Description
Technical field
The utility model relates to a kind of mould, especially a kind of side plate punching die of U-shaped sheet metal component.
Background technology
The side blow hole of sheet metal component is generally adopted in automobile industry, and in the punching course, this situation occurs through regular meeting: the size tolerance requirements of the position in hole is very high on the target product.And the tolerance of the material of buying is according to the concerned countries standard, and particularly the hot rolled plate tolerance is 10% of a material thickness, and promptly material tolerances is far longer than the status requirement in hole! Go punching by conventional method, the product of making probably can form in batches to be scrapped.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, can improve the side plate punching die of the U-shaped sheet metal component of machining accuracy when a kind of the use is provided greatly.
The technical scheme that provides according to the utility model, the side plate punching die of described U-shaped sheet metal component, comprise cope match-plate pattern, backing plate, holding pad, die and lower bolster, lower surface at cope match-plate pattern is installed with backing plate, on holding pad, be installed with the discharging screw, the top ends of discharging screw has spacing outer step, offer jack on the discharging screw on the cope match-plate pattern, on the discharging screw, have in the jack spacing in step, step cooperates with spacing outer step in spacing, offering jack under the discharging screw on the backing plate, described discharging screw is upward through under the discharging screw and inserts behind the jack on the discharging screw in the jack; The holding pad support spring is installed on cope match-plate pattern, and described holding pad support spring and holding pad offset; The place, inside and outside two ends of corresponding die is plugged with the die limiting plate on lower bolster, offers the limiting plate slot at the inside and outside two ends of die, and described die limiting plate closely is plugged in the corresponding limiting plate slot; Place, inside and outside two ends at die is plugged with the workpiece limiting plate; Be plugged with the die support spring on lower bolster, the die support spring is described die jack-up, makes to have the gap between the upper surface of the lower surface of die and lower bolster.
The gap that has 1 ~ 2mm between the lower surface of described die and the upper surface of lower bolster.The left and right both ends of corresponding die are plugged with discharge plate on lower bolster.The left and right two ends of corresponding die are installed with the die steel bushing in die.
The utility model can improve machining accuracy in use greatly, and simple in structure.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the side plate punching die of this U-shaped sheet metal component, comprise cope match-plate pattern 1, backing plate 2, holding pad 3, die 4 and lower bolster 5, lower surface at cope match-plate pattern 1 is installed with backing plate 2, on holding pad 3, be installed with discharging screw 6, the top ends of discharging screw 6 has spacing outer step 6.1, offer jack 1.1 on the discharging screw on the cope match-plate pattern 1, on the discharging screw, have in the jack 1.1 spacing in step 1.2, step 1.2 cooperates with spacing outer step 6.1 in spacing, offering jack 2.1 under the discharging screw on the backing plate 2, described discharging screw 6 is upward through under the discharging screw jack 2.1 backs and inserts on the discharging screws in the jack 1.1; Holding pad support spring 7 is installed on cope match-plate pattern 1, and described holding pad support spring 7 offsets with holding pad 3; The place, inside and outside two ends of corresponding die 4 is plugged with die limiting plate 8 on lower bolster 5, offers the limiting plate slot at the inside and outside two ends of die 4, and described die limiting plate 8 closely is plugged in the corresponding limiting plate slot; Place, inside and outside two ends at die 4 is plugged with workpiece limiting plate 9; Be plugged with die support spring 10 on lower bolster 5, die support spring 10 is described die 4 jack-up, makes to have the gap between the upper surface of the lower surface of die 4 and lower bolster 5.
The gap that has 1 ~ 2mm between the upper surface of the lower surface of described die 4 and lower bolster 5.The left and right both ends of corresponding die 4 are plugged with discharge plate 11 on lower bolster 5.The left and right two ends of corresponding die 4 are installed with die steel bushing 12 in die 4.
The utility model is made die 4 unsteady, and it is by die support spring 10 jack-up, and the about 1 ~ 2mm(of the distance of emersion lower bolster 5 floats with die support spring 10 when punching press); Holding pad 3 is also made floating type, its pressured flitch support spring 7 jack-up; When cope match-plate pattern 1 moves downward, just be fitted on the holding pad 3 all the time with regard to workpiece 13 like this, datum level during punching just becomes the cover top surface of workpiece 13 like this, and punch 14 carries out punching from both sides to the side plate of U-shaped sheet metal component (being workpiece 13), thereby has guaranteed precision.
Die limiting plate 8 wherein is used for fixing and makes die 4 at four direction upper limit all around; Workpiece limiting plate 9 is used to make workpiece 4 at the inward-outward direction upper limit.
