Abstract
A kind of Bending Mould, comprise patrix (2) and the counterdie (4) of corresponding setting, described patrix (2) is provided with bending punching pin (6), described counterdie (4) is provided with the die cavity (7) matched with described bending punching pin (6), it is characterized in that: the sidewall of described die cavity (7) comprises cambered surface (10) and lower camber side (12), described upper cambered surface (10) is connected with lower camber side (12) by a roller that can rotate (8), described upper cambered surface (10) is a convex surface relative to bending punching pin (6), described lower camber side (12) is a concave surface relative to bending punching pin (6).The utility model has the advantage of long service life.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of Bending Mould.
Background technology
At present, die cutting die is generally made up of a punch and a die, multiple punch and multiple die also can be had to form, but can only complete a kind of blank operation in punch press one stroke.When External Shape is more complicated, just need to be made up of many secondary above single engineering die cutting dies, just can get a qualified product.This mould not only stability is not enough, and waste of manpower cost and machine cost.
Chinese patent Authorization Notice No. is CN203900258U, authorized announcement date is that the utility model patent on October 29th, 2014 discloses a kind of connection gasket cover continuous mould, comprise upper bolster, die shoe, and be arranged at upper bolster, the first punching die between die shoe, second punching die, three groups of cupping tools, punching die and rush salient point mould, described each group of mould comprises the patrix being connected to upper bolster and the counterdie being connected to die shoe respectively, patrix is corresponding with counterdie, patrix along with upper bolster to die shoe motion coordinate counterdie on die shoe respectively the material strip of paired pulses formula walking between each group of mould carry out operation.Although this utility model can with the connection gasket of speed of production production faster cover, can effectively reduce human cost and machine cost as seen, reduce the percent defective of product, visible have higher stability, but, find in Long-Time Service, the punching pin wearing and tearing when permanent use of this mould are very fast, especially bending punching pin, concrete bending punching pin can be subject to the reaction force of workpiece to it in the process of bending workpieces, larger active force is produced between the meeting of bending punching pin and the sidewall of die cavity under this reaction force, more unreasonable simultaneously again due to the design of die cavity side wall construction, therefore bending punching pin can be made to wear and tear very fast, thus reduce the whole mold use life-span.
Summary of the invention
Technical problem to be solved in the utility model is to provide longer Bending Mould in a kind of service life.
For solving the problem, the utility model provides a kind of Bending Mould, comprise the corresponding upper die and lower die arranged, described patrix is provided with bending punching pin, described counterdie is provided with the die cavity matched with described bending punching pin, the sidewall of described die cavity comprises cambered surface and lower camber side, and described upper cambered surface is connected with lower camber side by the roller that can rotate, described upper cambered surface is a convex surface relative to bending punching pin, and described lower camber side is a concave surface relative to bending punching pin.
Described bending punching pin is dismountable to be arranged on described patrix.
The radian of described upper cambered surface is greater than the radian of described lower camber side.
The arc length of described upper cambered surface is less than the arc length of described lower camber side.
The surface of described roller has elastic protective layer.
Described elastic protective layer is rubber layer.
Compared with prior art; the beneficial effects of the utility model are: because the utility model can make die cavity sidewall avoid contacting with bending punching pin; and bending punching pin straight down bending workpieces time tight and roller the contact of surface sliding; thus effectively can protect bending punching pin not by excessive friction; would not be worn and torn bending punching pin like this, thus the utility model can be made to have longer service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at the place of A shown in Fig. 1.
In figure: patrix 2, counterdie 4, bending punching pin 6, die cavity 7, roller 8, upper cambered surface 10, lower camber side 12.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of Bending Mould of the present utility model, comprise patrix 2 and the counterdie 4 of corresponding setting, dismountablely on patrix 2 be provided with bending punching pin 6, counterdie 4 is provided with the die cavity 7 matched with bending punching pin 6, special feature of the present utility model is: the sidewall of die cavity 7 comprises cambered surface 10 and lower camber side 12, wherein go up cambered surface 10 to be connected with lower camber side 12 by a roller that can rotate 8, go up cambered surface 10 relative to bending punching pin 6 is a convex surface simultaneously, lower camber side 12 is a concave surface relative to bending punching pin 6, the radian going up cambered surface 10 is more specifically greater than the radian of lower camber side 12, the arc length simultaneously going up cambered surface 10 is less than the arc length of described lower camber side (12), by this structural design, die cavity sidewall can be allowed to avoid contacting with bending punching pin 6, and bending punching pin 6 straight down bending workpieces time tight and roller 8 the contact of surface sliding, thus effectively can protect bending punching pin 6 not by excessive friction, would not be worn and torn bending punching pin 6 like this, thus the utility model can be made to have longer service life.
Actual use on the surface of roller 8, there is elastic protective layer, preferably this elastic protective layer be rubber layer, further can prevent bending punching pin 6 and roller 8 hard contact like this and the comparatively galling that causes.
