Abstract
The utility model discloses a kind of easily location stamping die backing plate, comprise the backing plate body of rectangle, be provided with the pit of reverse frustoconic in the middle part of described backing plate body, be provided with drift installing hole in pit bottom.The utility model structure is simple, reasonable in design, drift accurate positioning, effectively can ensure the uniformity at punch-center and mold center, press center, raising punching precision.
Description
Technical field
The utility model belongs to Stamping Die Technology field, particularly relates to a kind of diel backing plate.
Background technology
In recent years, along with punching automation line applying in Ge great automobile main frame maker, improve stamping production efficiency to a great extent.Punching production mode is changed to automation mode by manual mode.The robot line of domestic main flow is as COMAU, ABB, KUKA etc., and because flexibility is higher, running orbit point coordinates alterability is large, very high in punching automation initial stage applicability.Along with the production lot of main engine plants' punching press strengthens, production efficiency also wants corresponding raising, and the SPM of robot line only has 5 ~ 10 times, can not meet development trend, and therefore original robot automation's line has started to change to high-speed line.The generation of high-speed line, fundamentally changes the inefficient state of robot line, but also has higher requirement to the structure of mould aspects such as () uniformity at such as height of packing compact, mold center and press center simultaneously.
In punching die structure, the drift of cope match-plate pattern needs through backing plate and stretches out a part.Therefore, punch-center how is improved and mold center, press center uniformity become the direction that these those skilled in the art make great efforts.
Utility model content
The purpose of this utility model is just to provide a kind of easily location stamping die backing plate, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of easily location stamping die backing plate, comprises the backing plate body of rectangle, it is characterized in that: the pit being provided with reverse frustoconic in the middle part of described backing plate body, is provided with drift installing hole in pit bottom.
As a kind of preferred structure of the present utility model, described pit depth is 1/2nd of backing plate body thickness.
As a kind of preferred structure of the present utility model, there is positioning boss at described pit bottom center.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design, drift accurate positioning, effectively can ensure the uniformity at punch-center and mold center, press center, raising punching precision.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is the A-A sectional view in Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As depicted in figs. 1 and 2, a kind of easily location stamping die backing plate, comprises the backing plate body 1 of rectangle, is provided with the pit 2 of reverse frustoconic, is provided with drift installing hole 3 bottom pit 2 in the middle part of described backing plate body 1.
Described pit 2 degree of depth is 1/2nd of backing plate body 1 thickness.
In order to improve positioning precision further, there is positioning boss 4 in described pit 2 bottom centre.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
