Description

A kind of bending structure
Technical field
The utility model relates to die device technical field, especially a kind of bending structure.
Background technology
At present, when flexing movement is carried out to product, usual employing Mould operation, and the precision required by most of product that market is done is more and more higher, especially, in bending, the structure that bending and molding process is generally that die is fixed, punch and material lift block move downward, is easy to make the unstable or distortion of material strip in material lift, make when bending the surface of product leave scar, affect the qualification rate of product.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of bending structure, thus facilitates bending, protection material strip.
The technical scheme that the utility model adopts is as follows:
A kind of bending structure, comprise upper die component and lower mold assemblies, the structure of described upper die component is: comprise upper bolster, punch retainer is installed by convex mould pad in described upper bolster bottom, described punch retainer is fixed with punch, described upper bolster is fixed with push rod by securing member, and described push rod abuts with punch top through convex mould pad; The structure of described lower mold assemblies is: comprise die shoe, described die shoe installs die block by die backing plate, stripper is arranged at described die block top, described die block installs die, the side of described die has the first arc groove, the die block being positioned at die one end is provided with slide block, the side of described slide block has the second arc groove, be horizontally installed with lever between described slide block and die, the two ends of described lever coordinate with the first arc groove and the second arc groove respectively; Described punch retainer is provided with by securing member and makes bar, described bar of beating abuts with slide block through stripper.
Its further technical scheme is:
Described stripper has slot to make way.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, rationally, in use, can not need material lift, the feeding of its maximized guarantee product is smooth and easy, and can beat at a high speed, the machining accuracy of product have also been obtained very large raising simultaneously.
The utility model is mainly used in the mould of the product requiring the high speed stamping not doing material lift, utilize lever principle, by arm of force transmitting forces, die is made to do the motion of upwards lifting along with playing the downward motion of bar, punch first pushes down material strip under the effect of push rod, what continue along with punch retainer moves downward and finally kills material strip, and the motionless and bending of the process implementation product of die lifting of punch, this ensure that deformation of products is minimum in Forging Process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, upper bolster; 2, push rod; 3, convex mould pad; 4, punch retainer; 5, punch; 6, stripper; 7, die block; 8, die backing plate; 9, die shoe; 10, slide block; 11, lever; 12, die; 13, bar is made.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the bending structure of the present embodiment, comprise upper die component and lower mold assemblies, the structure of upper die component is: comprise upper bolster 1, punch retainer 4 is installed by convex mould pad 3 in upper bolster 1 bottom, punch retainer 4 is fixed with punch 5, upper bolster 1 is fixed with push rod 2 by securing member, push rod 2 abuts with punch 5 top through convex mould pad 3; The structure of lower mold assemblies is: comprise die shoe 9, die shoe 9 installs die block 7 by die backing plate 8, stripper 6 is arranged at die block 7 top, die block 7 is installed die 12, the side of die 12 has the first arc groove, the die block 7 being positioned at die 12 one end is provided with slide block 10, the side of slide block 10 has the second arc groove, be horizontally installed with lever 11 between slide block 10 and die 12, the two ends of lever 11 coordinate with the first arc groove and the second arc groove respectively; Punch retainer 4 is provided with by securing member and makes bar 13, make bar 13 and abut with slide block 10 through stripper 6.
Stripper 6 has slot to make way.
In actual use procedure, complete operation in the following way:
When patrix moves downward, punch 5 first pushes down material strip under the effect of push rod 2, along with lasting the moving downward of punch retainer 4 finally kills material strip, make bar 13 along with punch retainer 4 promotion slide block 10 downwards, slide block 10 makes lever 11 rotate counterclockwise, thus drive die 12 to do the motion of upwards lifting, such a construction ensures material strip is in one plane substantially, the amplitude of material lift is very little, it is very low that slot to make way on stripper 6 also can be opened, each bending material strip is very little relative to moving of punch-die, improves the precision of bending, also substantially increases punching speed.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
