Description

A kind of rotary Bending Mould of turnover panel

Technical field

This utility model relates to a kind of mould, particularly to a kind of rotary Bending Mould of turnover panel.

Background technology

Two strong points of the die of Bending Mould of the prior art, make arc-shaped, when bending, Workpiece slides on two circular arc fulcrums.As it is shown in figure 1, the wrap direction of this pattern is when bending, Point slides at surface of the work, easily causes workpiece surface damage, forms cut.

In view of drawbacks described above, this utility model creator obtains this reality through research and practice for a long time Use new technique scheme.

Utility model content

The purpose of this utility model is, it is provided that a kind of rotary Bending Mould of turnover panel, to overcome above-mentioned skill Art defect.

For achieving the above object, the technical solution adopted in the utility model is, it is provided that a kind of turnover panel rotates Formula Bending Mould, including a die socket and a punch, wherein, described die socket and punch are installed in one On workbench, the recess of described die socket is corresponding with the projection of described punch, and is positioned at same straight line On, described die socket can move left and right on described workbench, and described punch is fixed on described workbench On；The indent of described die socket is symmetrical arranged a rotation semiaxis, in the most symmetrical, described rotation Semiaxis is nested at the circular hole of described die socket；Arranging a turnover panel on described rotation semiaxis, its one end is fixed On described rotation semiaxis, the other end is free end, can rotate freely around described rotation semiaxis, and with institute The recess inner side plane stating die socket is at an angle.

Preferably, the diameter of described rotation semiaxis is slightly less than the Circularhole diameter of described die socket.

Preferably, described turnover panel is a L-shaped stalloy.

The beneficial effects of the utility model are compared with the prior art: this utility model Bending Mould is by former The point cantact wrap direction come between die socket with workpiece makes the wrap direction that face contacts into, decreases workpiece The cut on surface, improves the quality of workpiece.

Accompanying drawing explanation

Fig. 1 is the structural representation of Bending Mould in prior art.

Fig. 2 is the structural representation of the rotary Bending Mould of this utility model turnover panel.

Detailed description of the invention

Below in conjunction with accompanying drawing, to this utility model, above-mentioned and other technical characteristic and advantage are made in more detail Explanation.

Referring to shown in Fig. 2, a kind of rotary Bending Mould of turnover panel, it includes that a die socket 1 and is convex Mould 2, wherein, described die socket 1 and punch 2 are installed on a workbench 3, described die socket 1 Recess is corresponding with the projection of described punch 2, and is located on the same line, and described die socket 1 can be Move left and right on described workbench 3, and described punch 2 is fixed on described workbench 3；Described die The indent of seat 1 is symmetrical arranged a rotation semiaxis 4, and in the most symmetrical, described rotation semiaxis 4 is nested At the circular hole of described die socket 1, and the diameter of described rotation semiaxis 4 is slightly less than described die socket 1 Circularhole diameter, uses interference fit, prevents between the most described rotation semiaxis 4 and described die socket 1 circular hole Described rotation semiaxis 4 comes off from described die socket 1；One turnover panel 5, institute are set on described rotation semiaxis 4 Stating turnover panel 5 is a L-shaped stalloy, and its one end is fixed on described rotation semiaxis 4, and the other end is freely End, can rotate freely around described rotation semiaxis 4, and is one with the recess inner side plane of described die socket 1 Fixed angle, when the free end stress of described turnover panel 5, described turnover panel 5 is at described rotation semiaxis 4 The lower deflection of effect.

The operation principle of described Bending Mould is: first the workpiece needing bending abuts against described die socket 1 Front end, then move described die socket 1, by it near described punch 2, until workpiece and described punch 2 phases are touched, and the surface of workpiece is touched with described turnover panel 5 phase and slided on described turnover panel 5 simultaneously so that Described turnover panel 5 deflects under the effect of described rotation semiaxis 4, and last workpiece bending and molding then moves Described die socket 1, away from described punch 2, and mode manually makes described turnover panel 5 return to Original state.

Point cantact wrap direction between original die socket 1 and workpiece is made into by this utility model Bending Mould The wrap direction of face contact, decreases the cut of surface of the work, improves the quality of workpiece.

The foregoing is only preferred embodiment of the present utility model, be only explanation for this utility model Property, and nonrestrictive.Those skilled in the art should be appreciated that in this utility model claim institute It can be carried out many changes in the spirit and scope limited, amendment, even equivalence, will fall into this practicality In novel protection domain.

Claims (3)

1. the rotary Bending Mould of turnover panel, it is characterised in that include a die socket and a punch, its In, described die socket and punch are installed on a workbench, the recess of described die socket and described punch Projection corresponding, and be located on the same line, described die socket can move to right described workbench is upper left Move, and described punch is fixed on described workbench；The indent of described die socket is symmetrical arranged a rotation Semiaxis, in the most symmetrical, described rotation semiaxis is nested at the circular hole of described die socket；Described rotation Turning and arrange a turnover panel on semiaxis, its one end is fixed on described rotation semiaxis, and the other end is free end, can Rotate freely around described rotation semiaxis, and at an angle with the recess inner side plane of described die socket.
