Abstract
The invention discloses a locating block assembly for a bending die. The locating block assembly comprises a left locating block and a right locating block which are in bilateral symmetry. The locating blocks are in U shapes, and U-shaped openings of the two locating blocks are opposite. Each locating block is provided with a screw hole and two locating pin holes. The two locating pin holes in each locating block are symmetric in position. A guide arc is arranged at the upper end of the U-shaped portion of each locating block. According to the locating block assembly, the shape of the locating blocks is designed according to the appearance of a workpiece to be machined, the precise position of the pressure center is guaranteed, and the forming quality of the workpiece is effectively improved.
Description
Technical field
The present invention relates to dieparts, refer in particular to the locating piece assembly of positioning workpieces on a kind of bending die.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved the Sheet Metal Forming Technology method of certain angle, definite shape workpiece.Attachedly Figure 1 shows that middle hinge gasket piece, this part is typical V-arrangement part, workpiece shapes, relatively simple for structure, and symmetrical, and normally produce in enormous quantities, this part mainly contains Blanking Shaping and bending twice manufacturing procedure.In bending process, easily occur that pressurized central point offsets, affect the form and dimensional precision of workpiece.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the bending die locating piece assembly proposing a kind of registration.
Technical solution of the present invention is achieved in that a kind of bending die locating piece assembly, comprises two pieces of symmetrical locating pieces; Described locating piece is U-shaped, and the U-shaped opening of two pieces of locating pieces is relative; Described each locating piece offers a screw hole and two alignment pin nail; So the positional symmetry of two alignment pin nail.
Preferably, the upper end of the U-shaped portion position of described each locating piece is provided with guiding circular arc.
Preferably, the circular arc that described guiding circular arc is convex, and tangent with the vertical edges of U-shaped portion position.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Bending die locating piece assembly of the present invention, is arranged on bending die, workpiece can be placed on die accurately, thus ensures the accurate of centre-of-pressure position, effectively improves shaping and the dimensional accuracy of workpiece, improves the qualification rate of product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Attachedly Figure 1 shows that middle hinge gasket piece;
Accompanying drawing 2 is the structural representation of locating piece assembly of the present invention;
Accompanying drawing 3 is that the A-A of locating piece assembly of the present invention is to sectional view;
Wherein: 1, locating piece; 2, screw hole; 3, pin hole; 4, guiding circular arc.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is the finished product structure schematic diagram of the middle hinge gasket piece needing processing, and the knuckle of its finished work-piece is 90 °.
Bending die locating piece modular construction of the present invention, as shown in accompanying drawing 2,3, comprises two pieces of symmetrical locating pieces 1; Described locating piece 1 is U-shaped, and the U-shaped opening of two pieces of locating pieces 1 is relative; Described locating piece 1 designs according to the outline of workpiece to be processed; Described each locating piece 1 offers a screw hole 2 and two alignment pin nail 3; So the positional symmetry of two alignment pin nail; The upper end of the U-shaped portion position of described each locating piece is provided with guiding circular arc 4, and the circular arc that described guiding circular arc 4 is convex, and tangent with the vertical edges of U-shaped portion position, and the design of guiding circular arc 4 is to make workpiece put into the convenient and edge of work that can not wear and tear.
The bending die locating piece assembly of the present invention program, is arranged on bending die, and effect is to ensure that workpiece is placed on die accurately, thus ensures the accurate of centre-of-pressure position, effectively improves shaping and the dimensional accuracy of workpiece, improves the qualification rate of product.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
