The technical scheme of the utility model is that:

a one-time assembly closed forming die for small traveling nut pieces comprises a die holder 1, an unloader 2, a material receiver 3, an upper die 4, a hinge curved rod mechanism 5, a position fixing plate 6, a positioning plate 7, a driving plate 8, a machine tool spindle 9, a die rod 10, a magnet 11, a self-locking nut 12 and a dust cap 13.

The discharger 2 is of a T-shaped structure, and the vertical end of the discharger is installed on the die holder 1. The positioning plate 7 is used for placing a self-locking nut 12 and a dustproof cap 13, and is fixed on the die holder 1 and positioned below the horizontal end of the discharger 2.

The machine tool spindle 9 is connected with the upper die 4, and the machine tool spindle 9 is coaxial with the positioning plate 7 and the die rod 10 in the upper die 4. The die rod 10 penetrates through the horizontal end of the discharger 2 and is aligned with the center of the positioning plate 7; the bottom of the mold rod 10 is provided with a magnet 11.

Two ends of the position fixing plate 6 are respectively connected with the hinge curved bar mechanism 5 and the die holder 1; the middle part of the hinge curved bar mechanism 5 is fixedly connected with the material receiver 3. And two ends of the driving plate 8 are respectively hinged with the upper die 4 and the hinge curved bar mechanism 5.

During working, the closed tire mold is assembled and debugged, the dustproof cap 13 is firstly placed in the positioning plate 7 and then the self-locking nut 12 is placed during processing, the mold rod 10 moves downwards under the driving of the machine tool spindle 9, and the dustproof cap 13 and the self-locking nut 12 are combined in the positioning plate 7; meanwhile, the upper die 4 drives the driving plate 8 to change the angles of all the rods of the hinge curved rod mechanism 5, and the material receiver 3 moves backwards; when the mold rod 10 is lifted, the workpiece combined by the self-locking nut 12 and the dust cap 13 is attracted by the magnet 11 and continuously ascends, the upper mold 4 drives the driving plate 8 to enable the hinge curved rod mechanism 5 to change the angle, the material receiver 3 advances, the workpiece contacts the discharger 2 and then descends and enters the material receiver 3 to complete a cycle, and two processes of punching and material returning are realized through one-time pressing.

The utility model has the advantages that: the utility model discloses a child mould carries out half braking work, is applicable to the nut in the nut that moves about in the production and processing and rapid Assembly between the dust cap, has replaced the manual assembly method of tradition, and save time and labour have improved product quality and efficiency.

Detailed Description

The following embodiments of the present invention will be further explained with reference to the accompanying drawings, but the present invention is not limited thereto.

As shown in fig. 1-3, a closed forming die for one-step assembly of small traveling nut pieces comprises a die holder 1, an unloader 2, a material receiver 3, an upper die 4, a hinge curved bar mechanism 5, a retaining plate 6, a positioning plate 7, a driving plate 8, a machine tool spindle 9, a die bar 10, a magnet 11, a self-locking nut 12 and a dust cap 13.

The discharger 2 is of a T-shaped structure, and the vertical end of the discharger is arranged on the die holder 1.
