Abstract
The utility model relates to a hole flanging die for a sheet workpiece. The hole flanging die comprises a material discharging plate, a female die plate, a female die insert and a hole flanging punch, wherein the material discharging plate is arranged above the female die plate; a punch hole is formed in the material discharging plate; the hole flanging punch is inserted into the punch hole; the female die insert is arranged in the female die plate; a hole flanging cone is integrally connected with the bottom of the hole flanging punch and is a revolved body; the diameter of the hole flanging cone is gradually reduced from top to bottom; the generatrix of the hole flanging cone is convex; the bottom of the hole flanging cone is sharp; a scrap falling hole is formed in the female die insert; the diameter of the scrap falling hole is greater than that of the top of the hole flanging cone; and the scrap falling hole, the hole flanging cone and the hole flanging punch are coaxially arranged. By adoption of the hole flanging die, the quality of an end face subjected to hole flanging can be improved. Moreover, the hole flanging die is compact and reasonable in structure; and the working process is very easy and convenient.
Description
Technical field
The utility model relates to a kind of cold-punching mold, especially a kind of plate type part hole flanging mould.
Background technology
In prior art, general part is when carrying out hole flanging, and general way is a subpunch pre-punched hole on part; And then carry out hole flanging; The aspect ratio of hole flanging is lower like this, does not reach the size of appointment, and the end attenuation of hole flanging oral area is more serious; The edge easy of crack, the required precision that does not reach hole flanging.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of plate type part hole flanging mould that can improve hole flanging end face quality is provided.
According to the technical scheme that the utility model provides, said plate type part hole flanging mould comprises stripper, concave template, die mold insert and hole flanging drift; On concave template, be provided with stripper, on stripper, offer bore of the punch, in bore of the punch, be plugged with the hole flanging drift; In concave template, be provided with the die mold insert, the bottom of said hole flanging drift is connected with the hole flanging cone, and the hole flanging cone is a revolving body; The hole flanging cone is diameter from top to bottom and dwindles shape gradually; The pyramidal bus of hole flanging is an outer gibbosity, and the pyramidal bottom of hole flanging is a tip shape, on the die mold insert, offers the exfoliation hole; The diameter in exfoliation hole is greater than the diameter of hole flanging cone top ends, and the exfoliation hole, is coaxial setting with the hole flanging cone with the hole flanging drift.
The utility model can improve hole flanging end face quality when using, and the utility model compact conformation is reasonable, and the course of work is very easy.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, the utility model mainly is made up of with parts such as hole flanging drift 5, hole flanging cone 5.1 and binder springs 6 stripper 1, concave template 3, die mold insert 4, exfoliation hole 4.1.
This plate type part hole flanging mould comprises stripper 1, concave template 3, die mold insert 4 and hole flanging drift 5, on concave template 3, is provided with stripper 1; On stripper 1, offer bore of the punch, in bore of the punch, be plugged with hole flanging drift 5, in concave template 3, be provided with die mold insert 4; The bottom of said hole flanging drift 5 is connected with hole flanging cone 5.1; Hole flanging cone 5.1 is cone shape revolving body, and hole flanging cone 5.1 is diameter from top to bottom and dwindles shape gradually, and the bus of hole flanging cone 5.1 is an outer gibbosity; The bottom of hole flanging cone 5.1 is a tip shape; On die mold insert 4, offer exfoliation hole 4.1, the diameter in exfoliation hole 4.1 is greater than the diameter of hole flanging cone 5.1 top ends, and exfoliation hole 4.1, is coaxial setting with hole flanging cone 5.1 with hole flanging drift 5.
As shown in the figure, binder spring 6 is pushed down stripper 1, carries out binder then; Hole flanging drift 5 is descending, exposes outside the stripper 1, directly carries out hole flanging after part 2 contacts behind 5.1 pairs of pre-punched holes of the hole flanging cone of hole flanging drift 5 bottoms; Thereby recycle entire work process and steady.
