Abstract
The utility model discloses a kind of bending cutter, entirety is a cuboid, and lower end is the prominent shape of point, and top is provided with draw-in groove, and two side lower parts of described bending cutter are respectively provided with a rectangular indentation, and described rectangular indentation lower end is apart from bending cutter bottom from being no more than 10mm.The opening at its two ends, left and right, can be good at hiding the crimp of moulding of two places, completes smoothly the 3rd place's crimp, is conveniently used for making triangle part.
Description
Technical field
The utility model relates to machine-building die industry, is specifically related to a kind of bending cutter.
Background technology
Existing universal cutter be mainly used to be shaped straight flange, 90 ° or obtuse angle degree, in the time making many crimps, acute angle degree as leg-of-mutton part, as part in accompanying drawing 1, tend to occur to wipe touch, in the time of bending, when reaching after certain angle, the crimp of both sides can be encountered cutter and cannot be out of shape again, thereby can not get predetermined angle.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of convenience for making the bending cutter of triangle part.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of bending cutter, entirety is a cuboid, and lower end is the prominent shape of point, and top is provided with draw-in groove, and two side lower parts of described bending cutter are respectively provided with a rectangular indentation, and described rectangular indentation lower end is no more than 10 mm apart from bending cutter bottom.
As the further optimization of such scheme, the long 30mm of described rectangular indentation, wide 20mm.
As the further optimization of such scheme, described rectangular indentation bottom is stepped, to increase the hardness of bending cutter.
The beneficial effects of the utility model main manifestations is: use cutter of the present utility model, after two crimps of bending, in the time of the 3rd limit of processing, owing to having designed the opening at two ends, left and right, can be good at hiding the crimp of moulding of two places, complete smoothly the 3rd place's crimp, reach product requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the triangle part described in the utility model.
Fig. 2 is the side structure schematic diagram of bending cutter of the prior art.
Fig. 3 is the structural representation of the utility model one embodiment.
Wherein 1 is lower end, and 2 is first draw-in grooves, and 3 is second draw-in grooves, and 4 is first breach, the 5th, and first step, the 6th, bottom, the 7th, second step, 8 is second breach.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is done to more specific detail.
As shown in Figures 2 and 3, a kind of bending cutter, entirety is a cuboid, lower end 1 is the prominent shape of point, top is provided with the first draw-in groove 2 and the second draw-in groove 3, two side lower parts of described bending cutter are respectively provided with a rectangular indentation, are respectively the first breach 4 and the second breach 8, and described rectangular indentation lower end is no more than 10 mm apart from bending cutter bottom 6, the long 30mm of described the first breach and the second breach, wide 20mm, described rectangular indentation bottom is stepped, is respectively first step 5 and second step 7.
In actual applications, can carry out corresponding correction to tool dimension according to the height of the length of part and crimp, will ensure can be not too short because of tool length simultaneously yet, and cause defects such as " bulges " that cutter punching press causes, to the processing of opening part arc transition, alleviate as much as possible the adverse effects such as the gouge to part.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.
