Description

A kind of bending die locating piece assembly
Technical field
This utility model relates to dieparts, refers in particular to the locating piece assembly positioning workpiece 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. Accompanying drawing 1 show middle hinge gasket piece, and this part is typical chevron, workpiece shapes, relatively simple for structure, and symmetrical, it is common that produce in enormous quantities, and this part mainly has Blanking Shaping and bending twice manufacturing procedure. In bending process, it is easy to occur that pressurized central point offsets, affect the form and dimensional precision of workpiece.
Utility model content
This utility model is in order that overcome the deficiencies in the prior art and propose the bending die locating piece assembly of a kind of registration.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of bending die locating piece assembly, including 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, this utility model compared with prior art has the advantage that
Bending die locating piece assembly of the present utility model, is arranged on bending die, it is possible to be placed on die accurately by workpiece, thus ensureing the accurate of centre-of-pressure position, being effectively increased shaping and the dimensional accuracy of workpiece, improve the qualification rate of product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of locating piece assembly of the present utility model;
Accompanying drawing 2 is that the A-A of locating piece assembly of the present utility model 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 drawings and the specific embodiments, the utility model is described in further detail.
Bending die locating piece modular construction of the present utility model is such as shown in accompanying drawing 1,2, including 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 is that the outline according to workpiece to be processed designs; 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 will not wear and tear.
The bending die of this utility model scheme locating piece assembly, being arranged on bending die, effect is to ensure that workpiece is placed on die accurately, thus ensureing the accurate of centre-of-pressure position, it is effectively increased shaping and the dimensional accuracy of workpiece, improves the qualification rate of product.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation. The technical scheme that all employing equivalents or equivalence are replaced and formed, all falls within this utility model rights protection scope.
