Description

A kind of punching die

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of punching die.

Background technology

Punching die is low because of cost, and constant product quality can be processed the part of multiple performance, state, is subject in recent years applying more and more widely.Existing punching die is usually by piercing punch, the compositions such as die, but existing punching die is when converted products, piercing punch and die need to be separated, then product is installed on piercing punch, then with piercing punch and die to connecting, carry out punching, whole process relatively wastes time and energy, and is unfavorable for enhancing productivity.

The utility model content

The utility model has overcome the deficiencies in the prior art, provide a kind of simple in structure, lay the punching die that processed product is quick, production efficiency is high.

For achieving the above object, the technical solution adopted in the utility model is: a kind of punching die, comprise die shoe and upper bolster, described die shoe is provided with die, the described die shoe of described upper bolster subtend is provided with piercing punch, described piercing punch is provided with drift, it is characterized in that: be provided with some support columns between described die shoe and upper bolster, described upper bolster one end is connected with described support column pivotable.

In preferred embodiment of the utility model, comprise that further described support column one end is provided with horizontal circular hole, described upper bolster one end is provided with the through hole that runs through described upper bolster and with described circular hole, be communicated with.

In preferred embodiment of the utility model, comprise that further the both sides of described upper bolster one end are provided with the breach that holds described support column.

In preferred embodiment of the utility model, comprise that further described upper bolster is square, be provided with four support columns between described die shoe and described upper bolster.

In preferred embodiment of the utility model, comprise that further described breach is provided with fillet with the sidewall that described support column contacts.

In preferred embodiment of the utility model, comprise that further described four support columns fix by steady pin and described die shoe.

In preferred embodiment of the utility model, comprise that further the described upper bolster other end and described support column removably connect.

In preferred embodiment of the utility model, comprise that further the described upper bolster other end and described support column junction are provided with counterbore, described upper bolster and described support column are bolted.

The utility model has solved the defect that exists in the background technology, and the upper bolster of punching die of the present utility model adopts the design of upset, while laying processed product, more quick, improved production efficiency.

The specific embodiment

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1 to Figure 3, a kind of punching die, comprise die shoe 10 and upper bolster 20, and die shoe 10 is provided with die 30, and die 30 can be screwed on die shoe 10, fixes a blanking die on die 30, makes the punching again of the first blanking of this mould; Upper bolster 20 subtend die shoes 10 are provided with piercing punch 40, one stripper is installed on piercing punch 40, stripper can be connected by screw in upper bolster 20, also can be between upper bolster 20 and stripper elastic elements, spring element has certain pre compressed magnitude, is used for providing stripping force; Piercing punch 40 is provided with drift 41, drift 41 can be connected on guide pillar 42 by slide block, make drift 41 punching press downwards, and upwards return, specifically can open a window 25 on upper bolster 40, by control cabinet 80 control cylinders, the cylinder arm of cylinder is connected on slide block, drives drift 41 and moves back and forth; For convenience of processed product is placed on piercing punch 40, between die shoe 10 and upper bolster 20, some support columns 50 are set, upper bolster 20 1 ends are connected with two support column 50 pivotables wherein, upper bolster 20 can be overturn with respect to die shoe 10.

upper bolster 20 in the utility model is square, 50, four support columns of four support columns 50 can be set fixing with die shoe 10 by steady pin 60 on four angles of upper bolster 20 between die shoe 10, one end of upper bolster 20 with support 50 connected mode, specifically an end of two support columns 50 arranges horizontal circular hole 51 therein, the through hole 21 that runs through upper bolster 20 and with circular hole 51, be communicated with in an end setting of upper bolster 20, insert rotating shaft between circular hole 51 and through hole 21, can realize that upper bolster 20 is with respect to die shoe 10 upsets, while laying processed product, directly with under upper bolster 20 upsets, processed product is placed on piercing punch 40, again upper bolster 20 is fallen, the other end and support column 50 junctions at upper bolster 20 arrange counterbore 24, upper bolster 20 is connected with support column 50 by bolt 70, can realize the other end of upper bolster 20 and removably connecting of support column 50.Lay processed product by this kind mode, rapid and convenient, with respect to traditional product mode of putting, production efficiency is improved greatly.

For design for aesthetic, the breach 22 that hold support column 50 can be set in the both sides of upper bolster 20 1 ends, on breach 22 and sidewall that support column 50 contacts, fillet 23 is set, more smooth and easy while making upper bolster 20 overturn transition.

The upper bolster of punching die of the present utility model adopts the design of upset, while laying processed product, more quick, improved production efficiency.

Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine technical scope according to the claim scope.
