Description
Technical field
It the utility model is related to Stamping Die Technology field, and in particular to a kind of drawing trimming die.
Background technology
Trimming Die is device more commonly used in parts machining, and it is mainly by between deburring punch-pin and deburring cavity plate
Cooperation, cut off parts blank on a part, and then complete deburring shaping.
Trimming Die generally comprises the primary structures such as upper die and lower die, holding pad, edge iron, waste knife.Its course of work is big
Cause includes：Plate is put into lower mould, upper mould moves downward.Period material pressing core first touches plate, until upper mould edge contacts
To plate, i.e. binder process.Then, upper mould continues to move downward, and until cutting lower mould about 2~5mm, being acted on by edge iron will
One week waste material cut-out of technique supplement.Upper mould continues to move downward 3mm or so, waste knife work, by border waste material cutting section.
However, the waste knife of prior art is annular in shape in course of work deburring waste material, punch-pin periphery is remained in.When keeping this state without
Method is cleared up from mould.
Therefore, in view of the above-mentioned problems, the utility model proposes a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of registration, ensures deburring quality, while waste material excludes conveniently, to avoid
The drawing trimming die for the damage that waste material has to mould.
The utility model is achieved through the following technical solutions：
A kind of drawing trimming die, including upper die and lower die, the upper mould include upper bolster, cavity plate and die shank, the lower mould
Including die shoe, punch-pin and punch retainer, the upper bolster lower end is provided with cavity plate, and upper bolster upper end is provided with die shank, described recessed
Angled slide block is provided between mould, the angled slide block is connected with the knock-pin on upper bolster, and the die shoe upper end is provided with
Punch retainer, the punch retainer upper end are provided with punch-pin, and the punch-pin is engaged with cavity plate, are provided with and lead on the punch-pin
To block, the guide pad is engaged with angled slide block, and the punch-pin is surrounded by several waste material cutting cubes, waste material cutting cube upper end
For v-shaped structure.
Further, the number of waste material cutter is at least 2.
Further, the lugs position of the cavity plate close to product is provided with R angles.
Further, designed between the cavity plate and punch-pin using zero clearance.
The beneficial effects of the utility model are：The utility model proposes trimming die it is rational in infrastructure, can be accurately positioned, energy
Effectively ensure the precision of Product processing, ensure that the quality of deburring, meanwhile, it is convenient by the special construction of waste material cutting cube
Processing to waste material, avoid waste material has damage to mould.
