Abstract
The utility model discloses a drawing die for compensating the thicknesses of walls of parts, which relates to cold stamping drawing dies. The problem that the thickness of a wall of a transitional joint between a cylinder and the bottom of a part can be reduced easily during drawing is solved. The drawing die comprises a male die and a female die, wherein the female die matches with the male die, and a part withdrawing rod is mounted in the female die. The drawing die is characterized in that an expanded table of the male die is mounted on a die holder, a press plate and a support plate are sleeved on the male die, the press plate is connected with the die holder by a screw, an elastic component is mounted at the bottom of the die holder, an ejector rod is positioned between the support plate and the elastic component by the aid of the press plate and the die holder, and a positioning expanded table used for holding parts is arranged on an upper plane of the support plate. By the aid of the drawing die, the technical requirement that the thickness of the wall, which is located at a positioned easiest to be thinned by drawing, of a part is larger than 0.75t is met, and accordingly the quality of products is guaranteed.
Description
Technical field
The utility model relates to cold stamping, particularly the drawing die of flanged pin cylindrical member in the drawing.
Background technology
A kind of mould structure of wide flange deep drawn drawing part normally is made up of parts such as die, punch, positioning sleeve, pressing plate, push rod, die holders.Its operation principle is: be enclosed within part on the positioning sleeve, the die oral area comes downwards to fillet place, punch top and starts working, and the die oral area contacts with the part flange is an impulse stroke up to continuing to come downwards to.In the impulse stroke; Cylinder and bottom transition connecting portion bear the radially effect of tension and tangential stress always; And receive the pressure and the flecition of punch-nose angle; This part material attenuation is the most serious, especially walks to when contacting with the part flange in drawing process concave die orifice portion, draws thin or drawing crack the most easily.After can not satisfying the part stretching, the wall thickness of cylinder and bottom transition connecting portion is greater than 0.75 times the specification requirement of former plate t.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of drawing die that compensates the part wall thickness is provided, and part cylinder and bottom transition connecting portion wall thickness draw thin problem easily in the solution drawing process.
The technical scheme of the utility model:
A kind of drawing die that compensates the part wall thickness; Comprise: the punch that is connected with die holder; Cooperate with said punch, in the die that moves back the part bar is housed, it is characterized in that: the expansion platform of said punch is installed in the die holder, suit pressing plate and support plate on said punch; Said pressing plate and said die holder screw attachment; Elastomeric element is equipped with in said die holder bottom, and push rod sees through said pressing plate and die holder between said support plate and said elastomeric element, and the plane is provided with the location expansion platform of placing part on the said support plate.
Said elastomeric element can be rubber or spring.
The utility model compared with prior art owing to elastomeric element is housed, in drawing process in die holder bottom; Support plate is under the effect of elastomeric element; Can play supporting role to the tensile force that forms on the part, thereby reduce the part tension, the minimum wall thickness (MINI W.) place is compensated.Therefore, the utility model can satisfy part in the specification requirement of the wall thickness that draws thin place the most easily greater than 0.75t, thereby has guaranteed the quality of product.
Description of drawings
Fig. 1 is the utility model structural representation.
The utility model is done through most preferred embodiment below in conjunction with accompanying drawing and to be further described.
The specific embodiment
As shown in Figure 1, a kind of drawing die that compensates the part wall thickness is by elastomeric element 1, die holder 2, push rod 3, pressing plate 4, support plate 5, punch 6, die 7, move back major parts such as part bar 8 and form.Wherein be equipped with in the die 7 and move back part bar 8 and form patrix jointly with cope match-plate pattern; The expansion platform 6-1 of punch 6 is in die holder 2, and support plate 5, pressing plate 4 are enclosed within on the punch 6, and support plate 5 is positioned on the pressing plate 4; Pressing plate 4 and die holder 2 screw attachment; Elastomeric element 1 is equipped with in die holder 2 bottoms, and push rod 3 sees through pressing plate 4 and die holder 2 is formed counterdie between support plate 5 and elastomeric element 1, and support plate 5 can be moved up and down by the effect of part and elastomeric element 1.Elastomeric element 1 elastic construction that can be rubber, spring etc. have impetus to push rod 3 and support plate 5.The plane is provided with the location expansion platform 5-1 of part 9 on the support plate 5.
In drawing process, part 9 is shaped in the gap between die 7 and punch 6, and the tensile force that forms on the part when 5 pairs of dies of support plate 7 are descending plays supporting role, thereby reduces the part tension, makes the minimum wall thickness (MINI W.) place reach the effect of compensation.The compression of elastomeric element 1 and precompressed amount are adjustable.
The operation principle of the utility model:
Get part 9 and be enclosed within on the punch 6, the part flange is put into the expansion platform 5-1 of support plate 5, locates; Start lathe; Along with slide block down, die 7 lower surfaces and part bottom contact, and pushing away part 9, support plate 5 and push rod 3, to overcome the resistance continuation of elastomeric element 1 descending; Part 9 contacts with punch 6 tops, and die 7 begins the part on the support plate 59 is stretched.In this course, the part radially tension act on the elastomeric element 1 through support plate 5, push rod 3 by part wall portion and flange.When slide block down to die 7 lower surfaces contacted with the flange of part 9, it is maximum that the relative compression amount of elastomeric element 1 reaches, and the radially tension of part critical section obtains the maximum negative compensation, and part 9 relative strains dwindle.During backhaul, up along with slide block, part 9, is being withdrawed from from die 7 under the effect of lathe filling device by moving back part bar 8 during near top dead-centre from punch 6 or at slide block under the effect of elastomeric element 1 by support plate 5, push rod 3.
Claims (2)
1. drawing die that compensates the part wall thickness; Comprise: the punch (6) that is connected with die holder (2); Cooperate with said punch (6), in the die (7) that moves back part bar (8) is housed, it is characterized in that: the expansion platform (6-1) of said punch (6) is installed in the die holder (2), goes up suit pressing plate (4) and support plate (5) at said punch (6); Said pressing plate (4) and said die holder (2) screw attachment; Elastomeric element (1) is equipped with in said die holder (2) bottom, and push rod (3) sees through said pressing plate (4) and die holder (2) is positioned between said support plate (5) and the said elastomeric element (1), and said support plate (5) is gone up the plane and is provided with the location expansion platform (5-1) of placing part (9).
