Description
Technical field
A kind of punching die is the utility model is related to, belongs to field of die equipment.
Background technology
The side-wall hole or groove in metal pipe material are usually needed in machining produces, if added using brill or milling
Work, its workload is big, and operating efficiency is low and dangerous.Using perforating die punch press process, productivity ratio, and product can be improved
Steady quality, it is safe.But current punching die has in punch process that mold shock-absorbing capacity is poor, and workpiece
It is easy to the shortcomings that red needle is fixed and causes to be not readily separated.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of shock-absorbing capacity is good, and workpiece is easy to mould separation
Punching die.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of punching die, including cope plate and lower template, the lower surface of the cope plate are provided with upper padding plate, it is described on
The lower surface of backing plate is provided with red needle fixed plate, and the upper end of red needle passes through the red needle fixed plate and top and the upper padding plate
Lower surface is connected, and the lower end of the red needle passes through backing plate, is connected between the red needle fixed plate and the backing plate by spring, institute
The upper surface for stating lower template is connected with lower mould location-plate, and punch-pin, the punch-pin are provided with the internal cavities of the lower mould location-plate
Lower surface be connected with the upper surface of the lower template.
The cavity structure passed through for guide pin bushing upper end is offered at left and right sides of the cope plate, is provided with and leads in the guide pin bushing
Xiang Zhu, the lead lower end pass through the lower template.
The spring is arranged to 2, is symmetrically distributed in the both sides of the red needle.
Contact surface between the mould location-plate and the punch-pin is stepped for two level.
Fixed between the cope plate, upper padding plate and red needle fixed plate by screw.
The number of the red needle is 2.
The beneficial effects of the utility model：A kind of punching die provided by the utility model, the lower end of red needle 3 pass through pad
Plate 11, it is connected between red needle fixed plate 4 and backing plate 11 by spring 5, buffering can be played a part of, mitigates mould to workpiece
Impact, in addition after die punching, the elongation of the spring that compresses before, drive backing plate, separate red needle and workpiece.
Brief description of the drawings
Fig. 1 is a kind of structural representation of punching die of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
As shown in figure 1, a kind of punching die, including cope plate 1 and lower template 8, the lower surface of cope plate 1 are provided with pad
Plate 2, the lower surface of institute's upper padding plate 2 are provided with red needle fixed plate 4, and the upper end of red needle 3 passes through red needle fixed plate 4 and top and upper pad
The lower surface of plate 2 is connected, and the lower end of red needle 3 passes through backing plate 11, is connected between red needle fixed plate 4 and backing plate 11 by spring 5, under
The upper surface of template 8 is connected with lower mould location-plate 6, and punch-pin 7, the lower surface of punch-pin 7 are provided with the internal cavities of lower mould location-plate 6
It is connected with the upper surface of lower template 8.
The left and right sides of cope plate 1 offers the cavity structure passed through for the upper end of guide pin bushing 10, and guiding is provided with guide pin bushing 10
Post 9, the lower end of lead 9 pass through lower template 8, and main purpose is to be accurately positioned.In addition, after guide pin bushing 10 wears, Ke Yigeng
The guide pin bushing renewed, improve the mold use life-span；
Spring 5 is arranged to 2, is symmetrically distributed in the both sides of red needle 3.
Contact surface between lower mould location-plate 6 and punch-pin 7 is stepped for two level, including two vertical planes and a level
Face, extension is provided with left and right sides of the bottom of punch-pin 7, and lower mould location-plate 6 offers the groove for accommodating extension, this mode
Fixed effect is preferable.
Fixed between cope plate 1, upper padding plate 2 and red needle fixed plate 4 by screw, between lower mould location-plate 6 and lower template 8
It can also be fixed by screw.
The number of red needle 3 could be arranged to multiple, realize multiple punchings while workpiece, preferably 2 here.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
