Abstract
The invention relates to a punching and flanging die, which comprises an upper die, a lower die and a punch fixed on the upper die, wherein the punch comprises a column body and a head part connected with the column body; the head part comprises a cylindrical flanging section connected with the column body and a punching section positioned below the flanging section; the diameter of the flanging section is less than that of the column body; the diameter of the connection part between the punching section and the flanging section is less than that of the flanging section; the lower die is provided with a punched hole; the diameter of the punched hole is less than that of the column body of the punch and more than that of the flanging section; a sleeve and an elastic member are arranged in the punched hole; one end of the elastic member is fixedly connected with the bottom of the punched hole; the other end of the elastic member is fixedly connected with the sleeve; and the inside diameter of the sleeve is basically equal to the diameter of the connection part between the punching section and the flanging section. The punching and flanging die disclosed by the invention is capable of punching, discharging wastes and flanging at one time.
Description
Technical field
The present invention relates to the piercing and flanging mould, especially a kind of mould that is used for steel-sheet, can accomplishes punching and flange work a step.
Background technology
The flange hole is a common structure during sheet metal uses, and there are two kinds of ways in common flange hole in the industry.A kind of is the subpunch aperture, and then flange, and the shortcoming of this technology is to divide two work steps to accomplish, and efficient is low.Another kind of way is all to accomplish at same work step towards aperture and flange, but because technological problems often causes waste material when punching press, not come off fully, and waste material may be stayed on the part, also possibly drop on the mould, causes the bad or mould damage of part.
Summary of the invention
The object of the present invention is to provide an a kind of step to accomplish the piercing and flanging mould of punching, flange and the work of discharge waste material.
A kind of piercing and flanging mould, it comprises upper die and lower die and is fixed on the drift on the patrix.Said drift comprises shaft and the head that links to each other with shaft, and said head comprises cylindric flange section that links to each other with shaft and the punching section that is positioned at flange section below.The diameter of said flange section is less than the diameter of shaft, and the diameter of the part that said punching section links to each other with the flange section is less than the diameter of flange section.Have punching on the said counterdie, the diameter of said punching is established sleeve and elastic component less than the diameter of the shaft of said drift and greater than the diameter of flange section in the said punching.Said elastic component one end is fixedly connected with the punching bottom, and the other end is fixedly connected with sleeve; The internal diameter of said sleeve equals the diameter of the part that said punching section links to each other with the flange section basically.
In a preferred embodiment, said elastic component is a spring.
In a preferred embodiment, said punching section is cylindric.
In a preferred embodiment, said punching section is coniform.
Piercing and flanging mould of the present invention punching section is at work dashed a hole earlier on workpiece; Move downward then and stretch in the sleeve, accomplish the waste material work of discharging, this moment, the flange section pressed sleeve also to move downward; The work of completion flange, sleeve can reset under the effect of elastic component after drift resets.So, can accomplish the work of punching, discharge waste material and flange a step.
Description of drawings
Fig. 1 is first kind of working state figure of the piercing and flanging mould of an embodiment.
Fig. 2 is second kind of working state figure of the piercing and flanging mould of an embodiment.
The specific embodiment
To combine specific embodiment and accompanying drawing that piercing and flanging mould of the present invention is described in further detail below.
Fig. 1 shows the part-structure of piercing and flanging mould among the embodiment and the profile of a workpiece to be processed 800.This piercing and flanging mould mainly comprises the patrix (not shown), is fixed on drift 10 and counterdie 20 on the patrix.
Have punching 21 on the counterdie 20.The diameter of punching 21 is less than the diameter of shaft 11 and greater than the diameter of flange section 121.Establish sleeve 22 and elastic component 23 in the punching 21.Elastic component 23 1 ends are fixedly connected with punching 21 bottoms, and the other end is fixedly connected with an end of sleeve 22.Sleeve 22 is the cylindric of middle part perforate, the flush of its upper surface and counterdie 20, and its internal diameter equals the diameter of punching section 122 basically.
In the present embodiment, elastic component 23 is a spring.Among other embodiment, elastic component 23 can be shell fragment or inflatable elastic rubber blanket.
In the work, workpiece 800 lies in the upper surface of counterdie 20, and drift 10 impacts workpiece 800 downwards, and punching section 122 is gone out the hole that a diameter equals punching section 122 external diameters on workpiece, and punching section then 122 moves downward and stretches in the sleeve 22.In the moment of punching section 122 entering sleeves 22, the edge of punching section 122 is scissor with the inward flange cooperation of sleeve 22 cuts the waste material that still links to each other with workpiece on the workpiece 800, falls in the sleeve 22, accomplishes the waste material work of discharging.Then, flange section 121 is pressing sleeve 22 and elastic component 23 to move downward, and the position with the bore edges of workpiece 800 presses down simultaneously, accomplishes flange work.Thereby the work of disposable completion punching, discharge waste material and flange.After drift 10 resetted, sleeve 22 resetted under the effect of elastic component 23, got into punching next time and flange work.So, can one the step accomplish punching, discharge the work of waste material and flange, waste materials in stamping has just broken away from workpiece fully, can not cause the damage of the bad or mould of workpiece.
Though the description of this invention combines above specific embodiment to carry out,, those skilled in the art that can carry out many replacements, modification and variation according to above-mentioned content, be conspicuous.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
